     At present, An analytical equipment available in the market for detecting the substance content of various liquids, such as breast milk and milk, is mainly a large-scale testing equipment, the price of the large-scale testing equipment is high, the operation of the large-scale testing equipment is complicated, and special training is further required for operators. The above-mentioned testing equipment is mainly concentrated in hospitals or testing institutions, to provide substance content testing for those people in need. Therefore, some liquid need to be tested in the hospitals or the special testing institutions, the process is time-consuming and laborious, and for those people with testing requirements, regular testing is restricted. For liquid such as breast milk and milk that require frequent testing, it is particularly important to monitor the substance content regularly. Therefore, the inventor notices that providing an analyzer which is portable, compact, easy to operate, and can be used at home to detect the substance content of liquids, such as the breast milk, is of great significance. 
     A lab-on-a-chip refers to a technology that integrates or basically integrates basic operating units such as sample preparation, biological and chemical reactions, and separation detection into a chip, for example, with several square centimeters, for completing different biological or chemical reaction processes and analyzing products of above processes. The signal generated in the chip requires to be detected, and at present, the most commonly used detection methods include laser-induced fluorescence, mass spectrometry, ultraviolet, chemiluminescence, etc. 
     At least one embodiment of the present disclosure provides an analyzer and a detection system. The analyzer includes a first shell, a chip placement structure, and at least one detector unit. The chip placement structure is arranged in the first shell and is configured to place the detection chip, and the detection chip has at least one detection area. The at least one detector unit is arranged in the first shell, and the at least one detector unit is configured to detect one or more detection areas of the detection chip in the case where the detection chip is placed on the chip placement structure. 
     Because the detector module of the analyzer includes at least one detector unit, the analyzer can detect a plurality of detection areas of the detection chip during the detection process by the at least one detector unit, so that the contents of various substances in the liquid to be detected in the detection chip is detected. 
     Hereinafter, an analyzer and a detection system provided by one or more embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. 
     For example, in some examples,  FIG. 1A  is a schematic diagram of an analyzer provided by at least one embodiment of the present disclosure. As shown in  FIG. 1A , the analyzer  1100  includes a first shell  1110 , a second shell  1160 , and a chip placement structure  1120 . 
     The chip placement structure  1120  is located in the first shell  1110 , and is configured to place a detection chip  1200 . The first shell  1110  and the second shell  1160  can be opened and closed at a side, which is convenient for users to place and retrieve the detection chip  1200 , and avoid the interference of external light to the detection of the detection chip in the case where the analyzer  1100  is working. The analyzer  1100  further includes a detector unit, and the detector unit is located under the chip placement structure  1120  in the first shell  1110  to detect the substance content of the liquid to be detected in the detection chip  1200  placed on the chip placement structure  1120 . In the process of using, after preparing the detection chip  1200  containing a test sample, by user first opens the first shell  1110  and the second shell  1160 , places the detection chip  1200  on the chip placement structure  1120 , and then closes the first shell  1110  and the second shell  1160 . The analyzer  1100  can detect the substance content of the liquid to be detected in the detection chip  1200 , and after that the detection is completed, detection results are output. Finally the user can open the first shell  1110  and the second shell  1160  again, and take out the detection chip  1200 . 
     For example, in some examples, the chip placement structure  1120  is a lower “concave” accommodating space formed in the first shell  1110  from an opening (for example, a circular opening  1301   a  of the first shielding plate  1301  in  FIG. 2 ) in the upper surface of the first shell  1110  (for example, formed by a surface of the first shielding plate  1301  in  FIG. 2 ). For example, a cross section of the accommodating space is substantially in a circular shape. It should be noted that, the cross section can also be other shapes, such as a rectangular shape, an oval shape, etc. For example, as shown in  FIG. 2 , the chip placement structure  1120  is a space composed of the opening  1301   a  of the first shielding plate  1301 , an inner sidewall of the light splitter disk  1141 , and an upper surface (as shown in  FIG. 6A ) of a separator component  1150  (as shown in  FIG. 4A ). It should be noted that, the structure of the first shielding plate  1301 , the light splitter disk  1141 , and the separator component  1150  will be described in detail in the following. 
     For example, in other embodiments, the second shell  1160  of the analyzer  1100  can be removed, for example, the upper surface of the first shell  1110  is made into a plane that can shield light, an opening is arranged at a side surface of the first shell  1110 , and the opening is communicated with the chip placement structure  1120 . An object stage can be added on the chip placement structure  1120 , the object stage can be ejected from the opening of the chip placement structure  1120  to place the detection chip  1200  on the object stage, and then the object stage is pushed into the chip placement structure  1120  to detect the detection chip  1200 . It should be noted that, an operation of the object stage can be chosen to be a drawer type, and ambient light is shielded in the case where the detection chip  1200  is detected. The embodiments of the present disclosure is not limited by the shape and the structure of the second shell  1160 . 
     For example, in other embodiments, the chip placement structure  1120  can also be configured as a plurality of cross beams erected on the opening  1301   a  of the first shielding plate  1301 , and the detection chip  1200  can be directly placed on the beams. In addition, the beams can also be made of transparent material, or the positions of the beams are staggered from the detection areas of the detection chip  1200 . For another example, a plurality of fulcrums may be arranged at the side wall of the chip placement structure  1120 , the detection chip  1200  is arranged with a plurality of notches on the lower surface corresponding to the positions of the plurality of fulcrums. In the case where the detection chip  1200  is placed on the chip placement structure  1120 , the plurality of fulcrums cooperate with the notches of the detection chip  1200  to stably place the detection chip  1200 . For another example, a clamping mechanism may be arranged at the side wall of the chip placement structure  1120 , the detection chip  1200  is stably placed in the chip placement structure  1120  by the clamping mechanism. For another example, the chip placement structure  1120  may also include a platform that can be raised and lowered to put the detection chip  1200  on the platform for detection. A carrying portion of the platform may include a transparent structure, or a light-transmitting structure (for example, a light through hole) is arranged in a portion corresponding to the detection areas of the detection chip  1200 . It should be noted that, the detection chip  1200  in the present disclosure refers to a chip configured to integrate or substantially integrate of basic operating units such as sample preparation, biological and chemical reactions, and separation detection into a piece of, for example, several square centimeters. For example, the detection chip  1200  may include a microfluidic chip, which is configured to detect the substance content of the liquid to be detected. 
     For example, in some examples,  FIG. 1B  is another schematic diagram of the analyzer provided by at least one embodiment of the present disclosure. As shown in  FIG. 1B , the first shell  1110  includes a first supporter portion  1111  and a second supporter portion  1112 . For example, the first supporter portion  1111  and the second supporter portion  1112  are arranged symmetrically with respect to a center line of the first shell  1110 . The first supporter portion  1111  and the second supporter portion  1112  are arranged at the bottom of the first shell  1110 , and for example, include supporting surfaces respectively. In this way, in the case where the analyzer is placed on the supporting surfaces, a stable support for the first shell  1110  on a plane is provided, and the first shell  1110  is prevented from tilting to cause a relative positional relationship between the internal structures of the analyzer  1100  to shift. 
       FIG. 2  is a structural schematic diagram of a lower portion of the analyzer provided by at least one embodiment of the present disclosure;  FIG. 3  is a schematic diagram of a partial structure of a lower portion of the analyzer provided by at least one embodiment of the present disclosure;  FIG. 4A  is a structural schematic diagram of a detector module and an optical path component of the analyzer provided by at least one embodiment of the disclosure. 
     As shown in  FIG. 2 ,  FIG. 3 , and  FIG. 4A , the lower portion of the analyzer  1100  includes a first shell  1110  and a chip placement structure  1120 . The detection chip  1200  includes a plurality of detection areas, and the detailed structure of the detection chip  1200  can refer to  FIG. 12A ,  FIG. 12B , and  FIG. 12C  described in the following. In the examples in the figures, the chip placement structure  1120  provides a chamber for accommodating and supporting the detection chip  1200  and the chamber has substantially the same cross-sectional shape as the detection chip  1200 . For example, a circular chamber is shown in the figures, the chip placement structure  1120  may also include a clamping structure to fix the inserted detection chip. For example, the clamping structure includes a limiter block, which is not limited in the embodiments of the present disclosure. 
     The lower portion of the analyzer  1100  further includes a detector unit for detecting the inserted detection chip  1200 . The detector unit may include of various types, for example, including but not limited to photoelectric detector units. The detector unit is arranged in the first shell  1110 . In the following descriptions, the photoelectric detector units are taken as an example for description. As shown in  FIG. 4A , the detector unit includes at least one photoelectric detector units. The photoelectric detector unit may include of various types, for example, including but not limited to photoelectric detector units  1131 . These photoelectric detector units  1131  are configured to detect the plurality of detection areas of the detection chip  1200  in the case where the detection chip  1200  is placed on the chip placement structure  1120 , and specific exemplary descriptions are as follows. For example, a notch can be arranged in a circumferential direction of the detection chip  1200 , and the shape of the notch is the same as the shape of the limiter block of the chip placement structure  1120 , so that in the case where the detection chip  1200  is placed on the chip placement structure  1120 , the notch of the detection chip  1200  is sleeved at the limiter block, and the detection areas of the detection chip  1200  and the photoelectric detector units  1131  are aligned in a direction perpendicular to the photoelectric detector units  1131 , thereby allowing the user to place the detection chip  1200  on the chip placement structure  1120  more conveniently and accurately. The embodiments of the present disclosure may also adopt other alignment methods. For example, positioning marks or positioning springs are arranged on the chip placement structure  1120  to align with the detection chip  1200 . The embodiments of the present disclosure are not limited to this. 
     In some embodiments, an outer surface of the first shell  1110  is approximately in a semi-spherical shape, the chip placement structure  1120  is located in the first shell  1110  close to the upper side of the first shell  1110  to facilitate the insertion of the detection chip. The chip placement structure  1120  includes a first shielding plate  1301 , the first shielding plate  1301  is connected with the upper side of the first shell  1110 , for example, by a method of snap connection, or a method of screw connection. An opening  1301   a  is arranged at a center of the first shielding plate  1301  to form a space for placing the detection chip  1200  in the first shell  1110  to provide an accommodation chamber. The first shielding plate  1301  can shield other stray light outside the first shell  1110  to avoid interference of other light rays on the detection result. For example, the accommodation chamber of the chip placement structure  1120  is in a cylindrical shape to match the shape of the detection chip  1200 . The chip placement structure may also have other shapes, such as a quadrilateral shape, a polygonal shape, etc., which are not limited in the embodiments of the present disclosure. 
     For example, in other examples, the first shell  1110  may also have other shapes, such as a rectangular parallelepiped, etc., which are not limited in the embodiments of the present disclosure. 
     As shown in  FIG. 4A , the lower portion of the analyzer  1100  further includes a detection circuit board  1302 , the detection circuit board  1302  is arranged under the chip placement structure  1120  in the first shell  1110 . The detector unit is arranged on the detection circuit board  1302  and corresponds to the detection chip  1200  in an axial direction of the first shell  1110 . The detector unit includes a plurality of photoelectric detector units  1131 , the plurality of photoelectric detector units  1131  respectively correspond to the plurality of detection areas of the detection chip in the axial direction of the first shell  1110 . 
     For example, as shown in  FIG. 4A , a plurality of photoelectric detector units  1131  are evenly arranged on a same circumference to respectively detect the plurality of detection areas of the detection chip  1200 , for example, to detect the plurality of detection areas of the detection chip  1200  at the same time, or to detect the plurality of detection areas of the detection chip  1200  in a certain order, so that the contents of various substances in the liquid to be detected in the detection chip  1200  are detected. With the structure design that the plurality of photoelectric detector units  1131  are evenly arranged on the same circumference, the crosstalk of light can avoid in different photoelectric detector units, and the accuracy of optical detection can be realized. 
     It should be noted that, the plurality of detection areas of the detection chip  1200  are arranged on the same circumference, the plurality of corresponding photoelectric detector units  1131  are evenly arranged on the same circumference. In the case where the plurality of detection areas of the detection chip  1200  are arranged on the same circumference, and in the case where a sample is injected from the center of the detection chip  1200 , sample injection distances of the plurality of detection areas are the same, so that uniform sample injection can be achieved. 
     For example, in other embodiments, the plurality of photoelectric detector units  1131  can also be evenly arranged on vertices of a regular polygonal shape, so that the sample injection distances of the plurality of detection areas of the corresponding detection chip are the same. Of course, without considering the sample injection distances of the detection areas of the detection chip, the plurality of photoelectric detector units  1131  can also be arranged in various shapes, for example, can be arranged in a row, or a matrix, etc. The embodiments of the present disclosure is not limited to the arrangement of the plurality of photoelectric detector units  1131 . 
     For example, in some examples, each of the plurality of photoelectric detector units  1131  includes at least one light-emitter element and at least one photoelectric sensor device. In an example as shown in  FIG. 4A , the plurality of photoelectric detector units  1131  respectively includes two photoelectric light-emitter elements  1132  and a photoelectric sensor device  1133 . The two photoelectric light-emitter elements  1132  (for example, are symmetrical) are located at two sides of the photoelectric sensor device  1133 . For example, a distance between two adjacent photoelectric light-emitter elements  1132  located in different photoelectric detector units  1131  is greater than a distance between the photoelectric light-emitter element  1132  and the photoelectric sensor device  1133  in a same photoelectric detector unit  1131 , so that interference of light signals between different photoelectric detector units  1131  is avoided. The arrangement of two photoelectric light-emitter elements  1132  and one photoelectric sensor device  1133  can ensure that the light emitted by the light-emitter elements  1132  is evenly incident on the detection areas of the detection chip  1200 , and the arrangement can also increase the intensity of the incident light provided by the two light-emitter elements  1132  and the intensity of the reflected light after being reflected by the detection chip  1200 , and then the detection stability of the analyzer is improved. 
     For example, the distance between two adjacent light-emitter elements  1132  in different photoelectric detector units  1131 , for example, a linear distance between centers of two adjacent light-emitter elements  1132  ranges from 5 mm to 8 mm. For another example, in  FIG. 4A , the linear distance between the centers of two adjacent light-emitter elements  1132  is about 6 mm. For example, in the same photoelectric detector unit  1131 , a linear distance between a center of one of the two light-emitter elements  1132  and a center of the photoelectric sensor device  1133  ranges from 2.5 mm to 4 mm. For another example, in  FIG. 4A , the linear distance between the center of one of the two light-emitter elements  1132  and the center of the photoelectric sensor device  1133  is about 3 mm. For example, the distance between the centers of two adjacent photoelectric detector units  1131  on the circumference ranges from 10 mm to 15 mm. For another example, in  FIG. 4A , the distance between the centers of two adjacent photoelectric detector units  1131  on the circumference is 12.5 mm. It should be noted that, the word “about” means that the value can be varied within, for example, ±15% of the value. 
     For example, in some examples, as shown in  FIG. 4A , for example, the number of the plurality of photoelectric detector units  1131  is six. For another example, the number of the photoelectric detector units  1131  can also be two, three, four, five, seven, etc., the number is determined according to the number of detection areas of the detection chip  1200 , and the embodiments of the present disclosure are not limited by the number of the plurality of photoelectric detector units  1131 . 
     For example, in other examples, the plurality of photoelectric detector unit  1131  respectively may also include a photoelectric sensor device  1133  and a light-emitter element  1132 , and the detection of the liquid to be detected in the detection area of the detection chip  1200  can also be realized. Alternatively, the photoelectric detector unit  1131  may also include a plurality of photoelectric sensor devices  1133  and a plurality of light-emitter elements  1132 , the plurality of photoelectric sensor devices  1133  can detect different substances in the liquid to be detected. The embodiments of the present disclosure are not limited by the number of the light-emitter elements  1132  and the number of the photoelectric sensor devices  1133 . 
     For example, the arrangements of the plurality of the photoelectric sensor devices  1133  and the plurality of the light-emitter elements  1132  of the photoelectric detector unit  1131  can be flexibly changed according to the requirements of the detection index of the liquid to be detected of the detection chip  1200 . For example, the plurality of the light-emitter elements  1132  surround the photoelectric sensor device  1133  in a manner of providing the moon with stars, or the plurality of the light-emitter elements  1132  are arranged in two rows at both sides of the photoelectric sensor device  1133 . 
       FIG. 5A  is a schematic diagram of a detection principle of the analyzer provided by at least one embodiment of the present disclosure. As shown in  FIG. 5A , the light-emitter elements  1132  are configured to generate light signals, a specific intensity light (incident light) emitted by the light-emitter elements  1132  is transmitted to the chip placement structure  1120  to reach the detection chip  1200  placed on the chip placement structure  1120 , and then the light reflected by the detection areas (the detection sample in the detection chip  1200 ) of the detection chip  1200  is received by the photoelectric sensor device  1133 . The photoelectric sensor device  1133  will receive light signals (reflected light), and convert the light signals into electrical signals. According to the electrical signals, the intensity of the light signals received by the photoelectric sensor device  1133  can be obtained. 
     For example, in other examples, the light-emitter element  1132  may also be arranged as one light-emitter element  1132 , that is, the light emitted by the one light-emitter element  1132  illuminates the detection areas of the detection chip  1200  as incident light. The detection principle of the embodiment of the present disclosure is not limited by the number of the light-emitter elements  1132 . 
     An absorbance value of the liquid to be detected is calculated according to the following formula:

                   =

                       I 
                     
                   
                 
               
               
                 
                   (

                   ) 
                 
               
             
           
         
       
     
     In the above formula, I 0  is intensity of incident light of the detection chip, I is intensity of reflected light of the detection chip, and A is an absorbance value. The content of the specific substance in the liquid to be detected has a linear relationship with the absorbance value. The incident light of a certain wavelength is incident on the detection areas of the detection chip  1200 , the liquid to be detected in the detection areas partially absorbs the light and then reflects the light, and the intensity of light absorbed has a linear relationship with the substance content of the liquid to be detected in a detection areas. After receiving the reflected light through the photoelectric sensor device  1133 , an electrical signal are obtained, and the intensity of the reflected light can be obtained according to the magnitude of the electrical signal. The intensity of the reflected light and the intensity of the incident light are used to obtain the absorbance value by the formula (1). 
     For example, in some examples, the light-emitter elements  1132  and the photoelectric sensor device  1133  of the analyzer  1100  need to be calibrated to ensure the stability of the light source of the analyzer  1100 . A standard gray scale plate is configured to calibrate the light emitted by the light-emitter elements  1132  of the analyzer  1100 . The standard gray scale plate is placed on the chip placement structure, and the absorbance value of the standard gray scale plate to the incident light of the light-emitter elements is a known standard absorbance value. The absorbance value obtained, after that the analyzer  1100  detects the standard gray scale plate, is compared with the standard absorbance value, and the light emitted by the light-emitter elements  1132  of the analyzer  1100  is calibrated according to a comparison result. 
     For example, a liquid with a known substance type and a known content can be used as a calibration test sample, after the analyzer  1100  detects the absorbance value of the calibration test sample, the coordinate points of the absorbance value A and the content C of the substance is obtained as shown in  FIG. 5B , for example, at points D 1 , D 2 , D 3 , D 4  and D 5 , and there is a linear relationship between the absorbance value A and the substance content C. After performing a linear fitting based on the above five points, a standard curve of the absorbance value A and the substance content C is obtained. It should be noted that, the five points in  FIG. 5B  are just an example, a variety of test samples can be used to obtain multiple points to obtain a standard curve, the embodiments of the present disclosure are not limited to the specific process of obtaining the standard curve. 
     For example, in some examples, according to the absorbance value obtained by detecting the liquid to be detected by the analyzer, the absorbance value is brought into the standard curve of absorbance value A and substance content C as shown in  FIG. 5B , and the content of the substance corresponding to the absorbance value of the liquid to be detected can be obtained. By separately detecting the liquid to be detected in the plurality of the detection areas of the detection chip  1200 , the contents of various substances in the liquid to be detected are obtained. 
     For example, in some examples, the light-emitter elements  1132  include light-emitting diodes (LEDs), the photoelectric sensor devices  1133  include photo-diodes (PDs), such as silicon photo-diodes. The light-emitting diodes can emit light of specific wavelengths (for example, infrared light, red light, green light, etc.), the light-emitting diode of specific wavelengths can be selected according to the type of the substance to be detected. The wavelengths of light emitted by the light-emitting diodes located in different photoelectric detector units  1131  are different, so that detecting various substances can be realized by using the plurality of the photoelectric detector units  1131 . For example, a photoelectric detector unit  1131  can select light-emitter elements that emit light with a wavelength of 630 nm, which is configured to detect the content of lactose and the content of fat in the liquid to be tested. A maximum absorption peak of light with a wavelength of 630 nm can be obtained, so that the photoelectric detector unit  1131  obtains the maximum receiving efficiency, thereby improving the accuracy of detection. For example, the photoelectric detector unit  1131  can also select light-emitter elements that emit light with a wavelength of 660 nm to detect the content of calcium and the content of protein in the liquid to be detected, and the maximum absorption peak of light with the wavelength of 660 nm can be obtained, so that the photoelectric detector unit  1131  obtains the maximum receiving efficiency, thereby improving the accuracy of detection. The photoelectric detector unit  1131  can also select light-emitter elements that emit light with a wavelength of 585 nm to detect the content of zinc in the liquid to be detected, and a maximum absorption peak of light with the wavelength of 585 nm can be obtained, so that the photoelectric detector unit  1131  obtains the maximum receiving efficiency, thereby improving the accuracy of detection. Therefore, the photoelectric sensor device  1133  of the photoelectric detector unit  1131  of the analyzer provided by the embodiments of the present disclosure can generate at least 5 detection signals (for example, corresponding to lactose, fat, zinc, calcium, and protein, respectively). 
     For example, in other embodiments, according to different reagents used in the detection areas of the detection chip  1200 , different wavelengths of light can be selected to detect various substances in the liquid to be detected. For example, in some examples, the lower portion of the analyzer  1100  further includes an optical path component, the optical path component is arranged in the first shell  1110  between the chip placement structure  1120  and the detector unit, and is configured to transmit the light emitted by at least one light-emitter element  1132  to the chip placement structure  1120 , and to transmit the light reflected from the detection chip  1200  placed on the chip placement structure  1120  to at least one photoelectric sensor device  1133 . The optical path component can avoid the interference of light signals between different photoelectric detector units  1131 , so that the reliability of the detection results is ensured. 
     For example, in some examples, as shown in  FIG. 4A  and  FIG. 6A , the optical path component includes a light splitter disk  1141 , which is arranged on the detector unit. The light splitter disk  1141  includes at least one group of light through holes  1142 , the at least one group of light through holes  1142  are evenly arranged on the same circumference of the light splitter disk  1141 , and correspond to a plurality of photoelectric detector units  1131  in a direction along an axis of the first shell  1110  respectively. 
     For example, in the present example, as shown in  FIG. 6A , for example, the number of groups of light through holes  1142  is six. For another example, the number of groups of the light through holes  1142  may also be two, three, four, five, seven, etc., which corresponds to the number of the photoelectric detector units  1131 . The embodiments of the present disclosure are not limited to the number of groups of the light through holes  1142 . 
     For example, in some examples, each group of light through holes  1142  includes at least one light-emitting through hole and at least one light-reflecting through hole, the at least one light-emitting through hole allows the light emitted by the light-emitter element  1132  of the corresponding photoelectric detector unit  1131  to pass through, the at least one light-reflecting through hole allows the light reflected from the detection chip  1200  placed on the chip placement structure  1120  to pass through so as to transmit to the photoelectric sensor device  1133  of the corresponding photoelectric detector unit  1131 . As shown in  FIG. 6A , each group of light through holes  1142  includes two light-emitting through holes  1143  and one light-reflecting through hole  1144 . The two light-emitting through holes  1143  are located at both sides of the light-reflecting through hole  1144 , the light-emitting through holes  1143  correspond to the light-emitter elements  1132  in the photoelectric detector unit  1131 , and the light-reflecting through hole  1144  corresponds to the photoelectric sensor device  1133  in the photoelectric detector unit  1131 . The light emitted by the light-emitter elements  1132  passes through the light-emitting through holes  1143  and then is incident on the chip placement structure  1120 , the light reflected from the detection chip  1200  placed on the chip placement structure  1120  passes through the light-reflecting through hole  1144  and then is received by the photoelectric sensor device  1133 . The arrangement of the light splitter disk  1141  can avoid the interference of light signals between different photoelectric detector units  1131 , so that the reliability of the detection results is ensured. 
     For example, in some examples, as shown in  FIG. 6B , the side wall of each of the light-emitting through holes  1143  of each group of light through holes  1142  is an inclined surface, the opening of each of the light-emitting through holes  1143  on the side facing away from the photoelectric detector units  1131  is larger than the opening of each the light-emitting through holes  1143  at the side close to the photoelectric detector units  1131 , so that the irradiation area of the light emitted by the light-emitter elements  1132  on the detection chip  1200  can be increased. An angle between the side wall of each of the light-emitting through holes  1143  and an X direction (perpendicular to the axial direction of the light splitter disk  1141 ) is a. The value range of the included angle α is, for example, from about 130 degrees to about 140 degrees, for another example, the value of the included angle α is about 135 degrees, so that the incident light passing through the light-emitting through holes  1143  is emitted along the inclined surface of the long side of the light-emitting through holes  1143 , the light can be better concentrated in the detection areas of the detection chip  1200 , and a divergence of the incident light is reduced. 
     For example, the side wall of the light-reflecting through hole  1144  of each group of light through holes  1142  is an inclined surface, the opening of the light-reflecting through hole  1144  on the side facing away from the photoelectric detector units  1131  is larger than the opening of the light-reflecting through hole  1144  at the side close to the photoelectric detector units  1131 , so that the interference between the light emitted by the light-emitter elements  1132  and the light reflected from the detection chip  1200  placed on the chip placement structure  1120  can be avoided. The angle between the side wall of the light-reflecting through hole  1144  and the X direction (perpendicular to the axial direction of the light splitter disk  1141 ) is β. The value range of the included angle β is, for example, from about 115 degrees to 125 degrees, for another example, the value of the included angle β is about 120 degrees. It should be noted that, the word “about” means that the value can be varied within, for example, ±15% of the value. 
     For example, in some examples, the light-emitting through holes  1143  include, for example, rectangular holes as shown in  FIG. 6A . The size range of the opening of each of the light-emitting through holes  1143  at the side close to the photoelectric detector units  1131  in a circumferential direction and a radial direction is, for example, from about 0.8 mm to 1 mm. For another example, the size of each of the light-emitting through holes  1143  in both the circumferential direction and the radial direction is, for example, about 0.8 mm. The light-reflecting through hole  1144  include, for example, a circular hole as shown in  FIG. 6A , and the value range of the diameter of the light-reflecting through hole  1144  is, for example, from about 0.8 mm to about 1 mm. For another example, the size of the opening of the light-reflecting through hole  1144  at the side close to the photoelectric detector unit  1131  in the circumferential direction, for example, is about 0.8 mm. It should be noted that, the word “about” means that the value can be varied within, for example, ±15% of the value. For another example, both the size of the light-emitting through holes  1143  and a diameter of the light reflecting through hole  1144  can be selected to be slightly larger than 1 mm according to the requirements of processing, so long as there is no optical crosstalk between two adjacent group of light through holes  1142 . The embodiments of the present disclosure is not limited by the specific size of the light-emitting through holes  1143  and the light reflecting through hole  1144 . 
     For example, in some examples, as shown in  FIG. 6A , the value range of a long side of the light-emitting through hole  1143  is, for example, from about 3.5 mm to about 4.5 mm, for another example, the value of the long side of the light-emitting through hole  1143  is about 4 mm. The value range of a short side of the light-emitting through hole  1143  is, for example, from about 3 mm to about 3.4 mm, for another example, the value of the short side of the light-emitting through hole  1143  is about 3.2 mm. It should be noted that, the word “about” means that the value can be varied within, for example, ±15% of the value. The light-emitting through holes  1143  include rectangular holes, so that the incident light passing through the light-emitting through holes  1143  is emitted along the inclined surfaces of the long side of the light-emitting through hole  1143 , the light can be better concentrated in the detection areas of the detection chip  1200 , and the divergence of the incident light is reduced. 
       FIG. 6C  is another cross-sectional schematic diagram of a group of light through holes of a light splitter disk provided by at least one embodiment of the present disclosure along the section line E-F in  FIG. 6A . As shown in  FIG. 6C , the light-reflecting through hole  1144  includes a first reflecting through sub-hole  1144   b  close to the first side of the light splitter disk  1141  (a lower side in the figure, that is, the side where the incident light enters), and a second reflecting through sub-hole  1144   a  close to the second side of the light splitter disk  1141  (the upper side in the figure, that is, the side where the reflected light is reflected). For example, the diameter of the first reflecting through sub-hole  1144   b  is smaller than the diameter of the second reflecting through sub-hole  1144   a , so that the light emitted from the light-emitting through holes  1143  can be shielded from entering the light-emitting through holes, and causing detection errors is avoided. 
     For example, the size range of the diameter of the first reflecting through sub-hole  1144   b  is, for example, from about 0.8 mm to about 1.2 mm. For another example, the size of the diameter of the first reflecting through sub-hole  1144   b  is, for example, about 1 mm. For example, the size range of the diameter of the second reflecting through sub-hole  1144   a  is, for example, from about 1.4 mm to about 1.8 mm. For another example, the size of the diameter of the second reflecting through sub-hole  1144   a  is, for example, about 1.6 mm. It should be noted that, the word “about” means that the value can be varied within, for example, ±15% of the value. Thus, the light emitted from the light-emitting through holes  1143  can be shielded from entering the light-emitting through holes, and causing detection errors is avoided, under this case, the reflected light entering the first reflecting through sub-hole  1144   b  is not reflected. 
     For another example, as shown in  FIG. 6C , an upper surface (for example, the surface close to the second side) of the light splitter disk  1141  includes at least one protrusion  1144   c . The protrusion  1144   c  protrudes obliquely from the side of the two light-emitting through holes  1143  close to the light-reflecting through hole  1144  to the second side in the direction close to the light-reflecting through hole  1144 . The first reflecting through sub-hole  1144   b  is located in the protrusion  1144   c , so that the light emitted from the light-emitting through holes  1143  can be shielded from entering the light-emitting through holes, and causing detection errors is avoided. 
     For another example, as shown in  FIG. 6C , the protrusion  1144   c  is in an annular shape, the protrusion  1144   c  surrounds the first reflecting through sub-hole  1144   b . The light emitted from the light-emitting through holes  1143  can be shielded from entering the light-emitting through holes, and causing detection errors is avoided. 
     For example, as shown in  FIG. 6C , the value range of the slope angle α of the protrusion  1144   c  is, for example, from about 130° to about 140°, for another example, the value of the slope angle α of the protrusion  1144   c  is, for example, about 135°. For example, the value range of the height of the protrusion  1144   c  protruding from the light-emitting through holes  1143  is, for example, from about 0.4 mm to about 0.6 mm, for another example, the height of the protrusion  1144   c  protruding from the light-emitting through holes  1143  is, for example, about 0.5 mm. For example, it should be noted that the word “about” means that the value can vary within, for example, ±15% of the value. Therefore, the inclined surface provided by the protrusion  1144   c  can shield the light emitted from the light-emitting through holes  1143  for the first reflecting through sub-hole  1144   b.    
     For example, in other examples, the shapes of the light-emitting through holes  1143  can also include a triangle shape, a circle shape, and a polygonal shape, etc., the shape of the light-reflecting through hole  1144  can also include a rectangle shape, a triangle shape, and a polygonal shape, etc., and the embodiments of the present disclosure is not limited by the shapes of the light-emitting through holes  1143  and the shape of the light-reflecting through hole  1144 . 
     For example, in some examples, the light splitter disk  1141  further includes at least one second positioning hole. As shown in  FIG. 6A , the light splitter disk  1141  includes three second positioning holes  1145 , which are evenly distributed on a same circumference. The number of the second positioning holes  1145  may also be two, four, etc., which is not limited in the embodiments of the present disclosure. As shown in  FIG. 4A , first positioning holes  1303  of the detection circuit board  1302  are provided at a positions of the detection circuit board  1302  opposite to the second positioning holes  1145  of the light splitter disk  1141 . The first positioning holes  1303  of the detection circuit board  1302  and the second positioning holes  1145  are configured to install and position of both the light splitter disk  1141  and the detection circuit board  1302 , so that the photoelectric detector units  1131  corresponds to the light through holes  1142 . 
     For example, in some examples, as shown in  FIG. 3  and  FIG. 6A , the light splitter disk  1141  further includes a limiter block  1146 , and the limiter block  1146  is arranged at the edge of the light splitter disk  1141 . The limiter block  1146  extends into the chip placement structure  1120  to match the shape of the detection chip  1200 . In the case where the detection chip  1200  is placed in the chip placement structure  1120 , the position of the detection chip  1200  is fixed, so that the plurality of detection areas of the detection chip  1200  correspond to the light through holes  1142  of the light splitter disk  1141  and the photoelectric detector units  1131  respectively. 
     For example, in other examples, the limiter block  1146  may also be arranged on other structures of the analyzer  1100 , such as the first shielding plate  1301 . For another example, the limiter block  1146  can also be replaced with other structures that can achieve alignment with the detection chip  1200 , which is not limited in the embodiments of the present disclosure. 
     For example, in other embodiments, the limiter block  1146  can also be replaced by a positioning pin or a positioning hole, and a corresponding matching structure is arranged on the detection chip  1200 . 
     For example, in some examples, as shown in  FIG. 4A , the lower portion of the analyzer  1100  further includes a separator component  1150 , such as, a partition plate, which is located in the first shell  1110  and is arranged between the optical path component and the chip placement structure  1120 . That is, the separator component  1150  is located above the optical path component and below the chip placement structure  1120 . The separator component  1150  includes a light-transmitter portion  1151 , which is configured to allow the light emitted by the light-emitter elements  1132  of the photoelectric detector units  1131  and the light reflected from the detection chip  1200  placed on the chip placement structure  1120  to pass through. The detection chip  1120  is located above the separator component  1150 , and the separator component  1150  is configured to prevent the penetration of the liquid to be detected in the detection areas of the detection chip  1120 . For example, the separator component  1150  can also provide protection functions for the optical path components arranged below. In other examples, the separator component  1150  arranged at the lower portion of the analyzer  1100  can be disassembled for easy replacement. 
     For example, in some examples, as shown in  FIG. 4A , the light-transmitter portion  1151  of the separator component  1150  includes at least one transparent window  1152 , which respectively corresponds to the plurality of photoelectric detector units  1131 , and respectively allows the light emitted from the at least one light-emitter element  1132  of the corresponding photoelectric detector unit  1131  and the light reflected from the detection chip  1200  placed on the chip placement structure  1120  to the at least one photoelectric sensor device  1133  of the corresponding photoelectric detector unit  1131  to pass through. 
     For example, in the example, as shown in  FIG. 4A , the number of the group of the transparent windows  1152  is, for example, six. For another example, the number of the group of the transparent windows  1152  can also be two, three, four, five, seven, etc., which corresponds to the number of the group of the light through holes  1142 . The embodiments of the present disclosure is not limited by the number of the group of the transparent windows  1152 . 
     For example, in some examples, as shown in  FIG. 4A  and  FIG. 4B , each of the transparent windows  1152  includes a first through hole  1153 , a first groove  1154 , and a transparent sheet  1155 . The diameter of the first through hole  1153  is smaller than the diameter of the first groove  1154 , the first groove  1154  is located at a side of the separator component  1150  close to the chip placement structure  1120 , and the first groove  1154  is configured to place the transparent sheet  1155 . The transparent sheet  1155  is placed in the first groove  1154 , which allows the light emitted by the two light-emitter elements  1132  of the corresponding photoelectric detector unit  1131  and the light reflected from the detection chip  1200  placed on the chip placement structure  1120  to the photoelectric sensor device  1133  of the corresponding photoelectric detector unit  1131  to pass through. 
     For example, the value range of the diameter of the transparent sheet  1155  is, for example, from about 5.5 mm to about 7 mm, for another example, the value of the diameter of the transparent sheet  1155  is, for example, about 6.3 mm. For example, the value range of the thickness of the transparent sheet  1155  is, for example, from about 0.3 mm to about 0.7 mm, for another example, the thickness of the transparent sheet  1155  is, for example, about 0.5 mm. The smaller the thickness of the transparent sheet  1155 , the better the light transmission, which is not limited in the present disclosure. For example, the value range of the diameter of the first through hole  1153  is, for example, from about 3 mm to about 3.8 mm, for another example, the value of the diameter of the first through hole  1153  is, for example, about 3.4 mm. It should be noted that, the word “about” means that the value can be varied within, for example, ±15% of the value. Therefore, the value of the diameter of the first through hole  1153  can allow the light incident from the light-emitting through holes  1143  on both sides of the light-reflecting through hole  1144  better converge in the detection areas of the detection chip  1200 , so that the divergence of incident light is reduced, and the detection accuracy is improved. 
     For example, in some examples, the transparent sheet  1155  may include a glass sheet or a transparent acrylic sheet, etc. 
     For example, in other examples, the light-transmitter portion  1151  may also be other light-transmitting structures, for example, a structure formed by a light-transmitting hole and the transparent sheet  1155 , or a structure formed by removing the transparent sheet  1155  in the transparent window  1152 . The embodiments of the present disclosure are not limited by the specific structure of the light-transmitter portion  1151 . 
     For example, in other examples, the separator component  1150  may also be an overall transparent structure without arranging the transparent window  1152 . For example, the separator component  1150  is made of transparent material, so that the separator component  1150  may allow the light emitted by the light-emitter elements  1132  of the photoelectric detector unit  1131  and the light reflected from the detection chip  1200  placed on the chip placement structure  1120  to the photoelectric sensor device  1133  of the corresponding photoelectric detector unit  1131  to pass through, and leakage of the liquid to be detected in the detection chip  1200  is prevent. The embodiments of the present disclosure are not limited to this. 
     In some other examples, the separator component  1150  may not be included, transparent windows are provided on the light through holes of the light splitter disk  1141 , under this case, the light splitter disk  1141  can also prevent the penetration of the liquid to be detected in the detection areas of the detection chip  1120 . 
     For example, in some examples, as shown in  FIG. 4A , the separator component  1150  further includes a plurality of positioning columns  1156 , which are arranged on a side of the separator component  1150  close to the light splitter disk  1141 . For another example, the separator component  1150  includes three positioning columns  1156 , the three positioning columns  1156  correspond to the positioning holes  1145  of the light splitter disk  1141  and the positioning holes  1303  of the detection circuit board  1302 . In addition, the positioning columns  1156  of the separator component  1150  are installed in the positioning holes  1145  of the light splitter disk  1141  and the positioning holes  1303  of the detection circuit board  1302 , so that the separator component  1150 , the light splitter disk  1141  and the detection circuit board  1302  are fixed, and the light-transmitter portion  1151  of the separator component  1150 , the light through hole  1142  of the light splitter disk  1141 , and the photoelectric detector unit  1131  correspond with each other in an axial direction of the first shell  1110 . 
     For example, in other examples, the second positioning holes  1145  are arranged at the separator component  1150 , the positioning columns  1156  are arranged at the light splitter disk  1141 , the positioning columns  1156  extend to the upper side and the lower side of the light splitter disk  1141 , the positioning columns  1156  can also be installed in the positioning holes  1145  of the light splitter disk  1141  and the positioning holes  1303  of the detection circuit board  1302 , so that the separator component  1150 , the light splitter disk  1141 , and the detection circuit board  1302  are fixed. The embodiments of the present disclosure is not limited by the installation method of the separator component  1150 , the light splitter disk  1141 , and the detection circuit board  1302 . 
     For example, in other examples, other methods can also be used to fix the separator component  1150 , the light splitter disk  1141 , and the detection circuit board  1302 , for example, using double-sided adhesive tape, or using lockers, etc. 
     For example, in some examples, as shown in  FIG. 7 , the analyzer  1100  further includes a second shell  1160 , and the second shell  1160  is connected to the first shell  1110 . The chip placement structure  1120  and the detector unit are arranged in a space enclosed by the first shell  1110  and the second shell  1160 . For example, in the present embodiment, the detector unit as shown in  FIG. 2  and  FIG. 3  is arranged on the detection circuit board  1302  and are located in the first shell  1110 . The first shell  1110  and the second shell  1160  are connected with each other at a first side  1161 , and the first shell  1110  and the second shell  1160  can be relatively closed and opened at a second side  1162 , so that the detection chip  1200  is placed on the chip placement structure  1120 , or the detection chip  1200  is taken out from the chip placement structure  1120 . It should be noted that, in the example as shown in the figure, the first side  1161  is a side that the first shell  1110  and the second shell  1160  are connected with each other, the second side  1162  is a side that the first shell  1110  and the second shell  1160  are relatively opened and closed, that is, the side that the detection chip  1200  is placed, the first side  1161  is arranged opposite to the second side  1162 , and the relative positions of the first side  1161  and the second side  1162  do not constitute a limitation to the embodiments of the present disclosure. The first shell  1110  is approximately in a hemispherical shape, and the shape of the opening below the first shell  1110  is the same as the shape of the opening above the second shell  1160 , so that a closed space that outside ambient light cannot be entered is formed in the case where the first shell  1110  and the second shell  1160  are closed to facilitate the detection of the analyzer  1100 . 
     For example, in other examples, the shape of the second shell  1160  may also be, for example, a cuboid, an opening shape of the second shell  1160  and an opening shape of the first shell  1110  are matched with each other, as long as the closed space can be formed, which is not limited in the embodiments of the present disclosure. 
     For example, in some examples, as shown in  FIG. 2  and  FIG. 7 , the second shell  1160  and the first shell  1110  are hinged. The second shell  1160  is configured to be closed with the first shell  1110  at the second side  1162 , and to be opened to expose the chip placement structure  1120 . The first side  1161  and the second side  1162  are arranged opposite to each other. 
     For example, in some examples, as shown in  FIG. 2 , the first shell  1110  and the second shell  1110  are hinged at the first side  1161  by a hinge shaft  1163 . A spring (such as a torsion spring) can also be arranged at the hinge shaft  1163 , so that after the first shell  1110  and the second shell  1160  are opened at the second side, the second shell  1160  will tilt up under the elastic force of the spring. 
     For example, in some examples, as shown in  FIG. 8 , the second shell  1160  further includes a second shielding plate  1304  that connected with the lower side of the second shell  1160 , for example, a snap connection, and a screw connection and so on. The second shielding plate  1304  and the first shielding plate  1301  in the first shell  1110  form an accommodating space together for the detection chip. The second shielding plate  1304  can shield other stray light in the second shell  1160  to avoid interference of other light on the detection result. 
     For example, in some examples, as shown in  FIG. 3  and  FIG. 8 , the first shell  1110  includes a first opening and closing sub-component  1181  arranged at the second side  1162 , the second shell  1160  includes a second opening and closing sub-component  1182  arranged at the second side  1162 . The first opening and closing sub-component  1181  and the second opening and closing sub-component  1182  are configured to be combined with each other and separated from each other, so that the first shell  1110  and the second shell  1160  can be closed and opened with each other, respectively. In the case where the first shell  1110  and the second shell  1160  are opened, the detection chip  1200  is placed on the chip placement structure  1120 , after that, the first shell  1110  and the second shell  1160  are closed, and then the substance detection is started. 
     As shown in  FIG. 3 ,  FIG. 8  and  FIG. 9 , the second opening and closing sub-component  1182  includes a first locking tongue  1183  with a long strip shape and a second locking tongue  1184  with a long strip shape, the first locking tongue  1183  and the second locking tongue  1184  are paired and arranged substantially side by side in the second shell  1160 . The first locking tongue  1183  and the second locking tongue  1184  may be fixed on the second shielding plate  1304 . The fixing method is, for example, a screw connection. A first end portion  1185  of the first locking tongue  1183  and a first end portion  1186  of the second locking tongue  1184  are exposed from the second shielding plate  1304 . The first opening and closing sub-component  1181  includes a groove  1187  and a locker  1188 , and the locker  1188  is located in the groove  1187 . The first end portion  1185  of the first locking tongue  1183  and the first end portion  1186  of the second locking tongue  1184  are configured to extend into the groove  1187  and be snapped with the locker  1188 , so that the first shell  1110  and the second shell  1160  can be closed and can be detached from the locker, thus the first shell  1110  and the second shell  1160  are opened. 
     For example, in some examples, as shown in  FIG. 8 , the analyzer  1100  further includes a fixing component  1309 , a middle portion of the first locking tongue  1183  and a middle portion of the second locking tongue  1184  are fixed at the second shielding plate  1304  by the fixing component  1309 . 
     For example, in some examples, the second opening and closing sub-component  1182  further includes an elastic component, the elastic component is arranged in both the middle portion of the first locking tongue  1183  and the middle portion of the second locking tongue  1184  to elastically connect the first locking tongue  1183  and the second locking tongue  1184 , and the elastic component is configured to apply elastic force to tend to place the first tongue  1183  and the second tongue  1184  in a state that the first tongue  1183  and the second tongue  1184  can be snapped with the locker  1188 . 
     For example, in some examples, as shown in  FIG. 9 , the elastic component includes a torsion spring  1190 , and the torsion spring  1190  is configured to apply an elastic force to allow the first end portion  1185  of the first locking tongue  1183  and the first end portion  1186  of the second locking tongue  1184  approach each other, so that the first end portion  1185  of the first locking tongue  1183  and the first end portion  1186  of the second locking tongue  1184  are in a clamped state. A second end portion  1194  of the first locking tongue  1183  and a second end portion  1195  of the second locking tongue  1184  extend to the outside of the second shell  1160 . 
     For example, in some examples, by reducing an opening distance between the second end portion  1194  of the first locking tongue  1183  and the second end portion  1195  of the second locking tongue  1184 , the first end portion  1185  of the first locking tongue  1183  and the first end portion  1186  of the second locking tongue  1184  are separated from the locker  1188  in a state of being snapped with the locker  1188 , so that the first shell  1110  and the second shell  1160  are opened. 
     For example, in some examples, the second opening and closing sub-component  1182  further includes switches, the switches are arranged in the middle portion of the first locking tongue  1183  and the middle portion of the second locking tongue  1184 , and the switches are connected with both the first locking tongue  1183  and the second locking tongue  1184 , respectively. In addition, the switches are configured to be operable, so that the first end portion  1185  of the first locking tongue  1183  and the first end portion  1186  of the second locking tongue  1184  are separated from the locker  1188  in a state of being snapped with the locker  1188 . 
     For example, in some examples, as shown in  FIG. 9 , the second opening and closing sub-component  1182  further includes a micro switch  1305   a  and a micro-switch  1305   b  the micro-switch  1305   a  is arranged at the second end portion  1194  of the first locking tongue  1183 , and the micro-switch  1305   b  is arranged at the second end portion  1195  of the second locking tongue  1184 . One of the micro-switch  1305   a  and the micro-switch  1305   b  is configured to realize the switch function of the analyzer  1100 , the other one of the micro-switch  1305   a  and the micro-switch  1305   b  is configured to realize the function of the analyzer  1100  to control the display of the detection results. For example, long time pressing the micro-switch  1305   a  will turn on the analyzer  1100 , and start the detection of the detection chip  1200 . Short time pressing the micro-switch  1305   a  will turn off the analyzer  1100 ; and pressing the micro-switch  1305   b  will select the detection results to be displayed. 
     For example, in some examples, as shown in  FIG. 9 , the second opening and closing sub-component  1182  further includes a rotating shaft  1189 , the middle portion of the first locking tongue  1183  and the middle portion of the second locking tongue  1184  are connected with each other, and the torsion spring  1190  is sleeved on the rotating shaft  1189 . 
     For example, in some examples, as shown in  FIG. 10 , a connector component  1192  is arranged in the middle portion of the first locking tongue  1183  of the second opening and closing sub-component  1182 , the surface of the connector component  1192  opposite to the second locking tongue  1184  is an inclined surface, to form a limiter track  1191 . The limiter track  1191  is configured to limit the opening and closing angles of the first locking tongue  1183  and the second locking tongue  1184  to prevent the opening distance between the first end portion  1185  of the first locking tongue  1183  and the first end portion  1186  of the second locking tongue  1184  from being too small, and to prevent the second end portion  1194  of the first locking tongue  1183  and the second end portion  1195  of the second locking tongue  1184  from being too large, which will cause the opening angle of the second shell  1160  relative to the first shell  1110  to be too large. For example, the angle between the second shell  1160  and the first shell  1110  is greater than 90 degrees, so that the second shell  1160  rolls over in a direction away from the second side  1162 , and the analyzer  1100  is at risk of dumping. 
     For example, in some examples, as shown in  FIG. 7 , the analyzer  1100  further includes a displayer device  1170 , which is arranged at the second shell  1160 . The displayer device  1170  may be, for example, a liquid crystal displayer device, an organic light-emitting diode (OLED) displayer device, an electronic paper, or a digital tube, which is used for displaying the detection results of the analyzer  1100 . 
     For example, in some examples, as shown in  FIG. 7 ,  FIG. 8 , and  FIG. 9 , the analyzer  1100  further includes a silicone sleeve  1306 , which is sleeved on the second end portion  1194  of the first locking tongue  1183  and the second end portion  1195  of the second locking tongue  1184 , to achieve the effects of being beautiful, being dustproof, and preventing light from entering the second shell  1160 . 
     For example, in some examples, as shown in  FIG. 9 , light shielding components  1193  are arranged on the first end portion  1185  of the first locking tongue  1183  and the first end portion  1186  of the second locking tongue  1184  respectively, to shield the light in the second shell  1160 . 
     For example, in some examples, as shown in  FIG. 5A , the analyzer  1100  further includes a controller device  1310 , which is connected in signal with the photoelectric detector units  1131  and the displayer device  1170 . The controller device  1310  is configured to receive detection results of the photoelectric detector units  1131  and send the detection results to the displayer device  1170 , and the displayer device  1170  can display the received detection results. For example, the controller device can include a processor and a memory, the processor can include a central processor unit (CPU) or a data processor (DSP), and the memory may include a semiconductor memory, which is configured to store computer codes for execution on the processor and for storing data. The controller device  1310  is also connected with the micro-switch  1305   a  and the micro-switch  1305   b  to perform a switching function of the analyzer  1100  and a function of controlling the display of the detection results on the displayer device  1170 . For example, long time pressing the micro-switch  1305   a  will turn on the analyzer  1100  and start the detection of the detection chip  1200 , short time pressing the micro-switch  1305   a  will turn off the analyzer; the display contents of the displayer device  1170  is controlled by pressing the micro-switch  1305   b , and the detection results can be viewed on the displayer device  1170  according to the selection. 
     For example, in some examples, as shown in  FIG. 5A , the analyzer  1100  further includes a sound generator device  1311 , and a signal transmitter and receiver device  1312 , etc. The sound generator device  1311  includes, for example, a speaker, which generates reminding sounds as requirements. The signal transmitter and receiver device  1312  includes, for example, an antenna, a modem, etc., which is configured to communication, for example, using bluetooth, WIFI, mobile communication (such as 2G/3G/4G/5G, etc.) to communicate, so that the detection results can be sent to other devices (for example, mobile terminals such as mobile phones, tablets, etc., or servers, etc.), for example, the detection results are uploaded to applications (APP) installed on mobile terminals such as mobile phones in real time. Or control signals received from other devices are used to control the operation of the analyzer by the controller device, for example, it is possible to cooperate with the analyzer  1100  by installing an application program (APP) on mobile terminals such as mobile phones. For example, in some examples, the analyzer  1100  further includes a temperature sensor, which is configured to monitor the ambient temperature of the analyzer  1100 . because some liquid to be detected have certain requirements for the temperature during detection, for example, the temperature needs to be approximately in the range of 25° C. to 35° C. Therefore, detecting the ambient temperature of the analyzer  1100  can ensure the accuracy of the detection results. 
     For example, in some examples, the analyzer  1100  may also include a humidity sensor, which is configured to detect the environmental humidity of the analyzer  1100 . In the process of detecting, some liquid to be detected have certain requirements for the humidity during detecting, for example, a color reaction occurs between the liquid to be detected and the test paper in the detection areas of the chip, in response to lower the humidity, the test paper may fade and affect the detect results. The control of the environmental humidity during the detection process helps to ensure the accuracy of the detection results. 
     For example, in some examples, as shown in  FIG. 3 , the analyzer  1100  further includes a battery  1307 , which is arranged in the first shell  1110 . The battery  1307  supplies power to each device in the analyzer  1100  that needs to use electric energy, for example, supplying power to the controller device, the displayer device, and the detector unit. For example, the battery  1307  may include a primary battery or a secondary battery, and the secondary battery may include a nickel-hydrogen battery, a nickel-cadmium battery, a lead-acid battery, and a lithium-ion battery, etc. The analyzer  1100  provided by the embodiments of the present disclosure has a simple structure, and a low power consumption, so that the analyzer  1100  has a long standby time to facilitate the usage of users. For another example, the analyzer  1100  can also use a power cable to provide electrical energy for various devices that need to use electrical energy. According to the requirements of the analyzer  1100  in usage, battery power supply or direct power supply can be selected. 
     For example, in some examples, as shown in  FIG. 3 , the analyzer  1100  further includes a counterweight  1308 , which is arranged in the first shell  1110  and is located under the battery  1307 . The counterweight  1308  is configured to move the center of gravity of the analyzer  1100  down, so that the analyzer  1100  is more stable as placed on a horizontal surface, and the detection chip  1200  can be made not easy to move in the case where the detection chip  1200  is placed on the chip placement structure  1120 , thereby ensuring the reliability of the detection results. 
     In addition, in at least one embodiment, the analyzer may have the characteristics of small size, simple structure, and easy operation, is suitable for use at home, and can monitor the content of various substances in liquid such as breast milk at any time. 
     Another embodiment of the present disclosure also provides an analyzer, as shown in  FIG. 11 , the analyzer includes a first shell  2110 , a chip placement structure  2120 , and a detector unit. The chip placement structure  2120  is arranged in the first shell  2110 , and is configure to place the detection chip  1200 . The detection chip  1200  includes at least one detection area. The detector unit is rotatably arranged in the first shell with respect to the chip placement structure  2120 , which includes, for example, a photoelectric detector unit, and the photoelectric detector unit includes, for example, at least one photoelectric detector unit  2132 , such as a single photoelectric detector unit. The photoelectric detector unit  2132  is configured to that in the case where the detection chip  1200  is placed on the chip placement structure  2120 , the plurality of detection areas of the detection chip  1200  can be respectively detected by relative rotation with the detection chip  1200 , for example, the detection chip  1200  can be rotated or the photoelectric detector unit can be rotated to detect the plurality of detection areas of the detection chip  1200  respectively. For example, the photoelectric detector unit  2132  includes at least one light-emitter element and at least one photoelectric sensor device, or for example, only includes a photoelectric sensor device. 
     In an example, the photoelectric detector unit  2132  of the analyzer is rotatably arranged in the first shell  2110  with respect to the chip placement structure  2120 , the analyzer can respectively detect the plurality of detection areas of the detection chip by a photoelectric detector unit of the detector unit, so that the content of various substances in the liquid to be detected in the detection chip is detected. In the example, the same light-emitter element included in the photoelectric detector unit  2132  can emit light of different wavelengths as required, to perform corresponding detections on different detection samples. 
     The structure difference between the analyzer provided in the embodiment and the previous embodiments is that: the detector unit in the embodiment is relatively rotatable with respect to the chip placement structure in the first shell, and the detector unit only includes at least one photoelectric detector unit. Hereinafter, the different portions of the structure of this embodiment and the previous embodiments will be introduced. 
     For example, in some examples, as shown in  FIG. 11 , the detector unit is arranged on the detection circuit board  2302 . A central axis  2400  is arranged at the center of the detection circuit board  2302 . The analyzer also includes a rotation driver device  2500 , which is connected with the controller device, in this way, the rotation driver device  2500  is controlled by the controller device. The rotation driver device  2500 , for example, may include a servo motor, or a stepping motor. The other end of the central axis  2400  is connected with the rotation driver device  2500 , the rotation driver device  2500  drives the central axis  2400  to rotate so as to drive the photoelectric detector unit  2132  of the detector unit to rotate relative to the chip placement structure  2120 . 
     For example, in some examples, at least one photoelectric detector unit includes one photoelectric detector unit, the rotation driver device is configured to drive a photoelectric detector unit to rotate with respect to the chip placement structure. 
     For example, in some examples, compared with the previous embodiments, the analyzer in the present embodiment can connect the light splitter disk of the optical path component and the separator component to the first shell, instead of connecting with the detection circuit board, which is ensured that the light through holes of the light splitter disk and the light-transmitter portion of the separator component correspond to the detection areas of the detection chip. 
     For another example, in some examples, compared with the previous embodiments, the analyzer of the present embodiment can change the light through holes of the light splitter disk of the optical path component and the light-transmitter portion of the partitioning component to one group, which corresponds to the detector unit. The light splitter disk and the separator component rotate together with the detection circuit board  2132 , the detection chip  1200  is placed on the chip placement structure  2120 , and the position of the detection chip  1200  does not move. For example, a limiting spring sheet can be arranged at the sidewall of the chip placement structure, and in the case where the detection chip  1200  is placed on the chip placement structure  2120 , the position of the detection chip is fixed. 
     For example, in some examples, the rotation driver device  2500  receives signals from the controller device and controls a rotation angle of the photoelectric detector unit  2132 , so that the photoelectric detector unit  2132  stops rotating in the case where the photoelectric detector unit  2132  rotates to a position corresponding to a detection area of the detection chip  1200 , the photoelectric detector unit  2132  detects the substance content in the detection area. The controller device receives an electrical signal from the photoelectric sensor device of the photoelectric detector unit  2132 , the photoelectric detector unit  2132  is rotated again to a position corresponding to another detection area of the detection chip  1200 , and then the substance content in the detection area is started to detect. According to the above method, the analyzer can sequentially detect the substance content in the plurality of detection areas of the detection chip  1200 , so that the contents of various substances in the liquid to be detected can be obtained. 
     At least one embodiment of the present disclosure provides a detection system, the detection system includes the analyzer and the detection chip described in any one of the above embodiments, for example, provided as a kit. The detection chip is configured to be placeable on the chip placement structure of the analyzer. 
       FIG. 12A  is a schematic diagram of a detection chip provided by at least one embodiment of the present disclosure;  FIG. 12B  is a schematic diagram of a partial structure of a detection chip provided by at least one embodiment of the present disclosure;  FIG. 12C  is an exploded schematic diagram of another detection chip provided by at least one embodiment of the present disclosure. 
     As shown in  FIG. 12A  and  FIG. 12B , the detection chip includes a cover plate  1201  and a substrate  1203 . The cover plate  1201  includes a sample injection opening  1202  and the cover plate  1201  is closely attached to the substrate  1203 . The substrate  1203  is made of a transparent material to allow the light emitted by the photoelectric detector units  1131  in the analyzer  1100  to enter the detection chip  1200  and the light reflected by the detection chip  1200  to be transmitted to the photoelectric detector units  1131 . 
     For example, in some examples, as shown in  FIG. 12B , a plurality of micro flow channels  1205 , a plurality of detection areas  1206 , and a calibration area  1207  are arranged on the surface of the cover plate  1201  opposite to the substrate  1203 . The detection chip includes five detection areas  1206 . Each of the detection areas  1206  is connected with one end of the plurality of micro flow channels  1205 , the other end of plurality of micro flow channels  1205  extend to the sample injection opening  1202  of the cover plate  1201 , so that the liquid to be detected enters the plurality of detection areas  1206  through the plurality of micro flow channels  1205 . For example, the center of the calibration area  1207  and the centers of the plurality of detection areas  1206  are arranged on the same circumference at equal intervals, the plurality of detection areas  1206  and the calibration area  1207  respectively correspond to the photoelectric detector units  1131  in the detector unit of the analyzer  1100 . The calibration area  1207  is configured to detect and systematically calibrate whether there is a detection chip  1200  on the chip placement structure  1120  in the analyzer  1100 . 
     For example, in the case where the detection chip  1200  is placed on the chip placement structure  1120 , the photoelectric detector unit  1131  corresponding to the calibration area  1207  can receive the reflected light, so that the photoelectric detector unit  1131  outputs an electrical signal, thereby determining that a detection chip  1200  is in the analyzer  1100  at this time, the controller device can control the detection work of other photoelectric detector units  1131  according to the electrical signal. Conversely, in the case where the detection chip  1200  is not placed on the chip placement structure  1120 , the photoelectric detector unit  1131  corresponding to the calibration area  1207  can receive the reflected light with very weak intensity, so that the photoelectric detector unit  1131  has no electrical signal output, thereby determining that no detection chip  1200  is in the analyzer  1100  under this case, and the analyzer  1100  does not perform detection. 
     Detection test paper placement areas  1208  are arranged in the plurality of detection area  1206 , and detection test papers are placed in the detection test paper placement areas  1208 , respectively. In addition, detection through holes  1209  are arranged at the center of the plurality of detection areas  1206 , respectively. The liquid to be detected enters the plurality of detection area  1206  and reacts with the detection test paper  1208  through the detection through holes  1209 , the degree of the color reaction can be observed, thereby judging whether the liquid to be detected is evenly distributed in the plurality of detection area  1206 . In addition, the detection through holes  1209  can also contain excess liquid to be detected. 
     For example, in some examples, as shown in  FIG. 12B , the plurality of detection areas  1206  of the detection chip  1200  is in a diamond shape. For example, the shape of the detection area  1206  may also include a circle shape, an ellipse shape, or a triangle shape. The embodiments of the present disclosure is not limited by the shape of the plurality of detection areas  1206 . 
     For example, in some examples, as shown in  FIG. 12A , the detection chip  1200  further includes a sample injection unit  1204 . For example, the sample injection unit includes a through hole in the center and is in a petal shape. The through hole of the sample injection unit  1204  is connected with the sample injection opening  1202  of the cover plate  1201 , and the liquid to be detected is dropped into the sample injection unit  1204 , after that, the detection liquid passes through the sample injection opening  1202  of the cover plate  1201 , enters the detection area  1206  of the detection chip through the micro-flow channel  1205 , and undergoes a color reaction with the detection test paper  1208 . 
     For example, in examples of other embodiments, as shown in  FIG. 12C , the sample injection unit  1204  may also be in a cylindrical shape. The embodiments of the present disclosure are not limited to the specific shape of the sample injection unit. 
     For example, in other examples, the number of the plurality of detection areas  1206 , for example, may also be two, three, four, six, seven, etc., which are not limited in the embodiments of the present disclosure. 
     For example, the calibration area  1207  in the detection chip is not necessary, and the detection chip may not be arranged with the calibration area  1207 . As shown in the example of  FIG. 12C , the detection chip includes six detection areas  1206 , and no calibration area  1207  is arranged. 
     For example, in some examples, as shown in  FIG. 12C , detection light through holes  1210  are arranged at positions of the substrate  1203  opposite to the detection through holes  1209  of the cover plate  1202 , which allow the light emitted by the photoelectric detector units  1131  in the analyzer  1100  to enter the detection chip  1200  and the light reflected by the detection chip  1200  to be transmitted to the photoelectric detector units  1131 . 
     For example, in some examples, the analyzer shown in  FIG. 1A  and  FIG. 1B  is configured to detect the substance content of the liquid, and the detection process includes the steps shown in  FIG. 13 . 
     Step S 100 : dropping the liquid to be detected into the detection chip. After that the liquid to be detected is evenly distributed in the plurality of detection areas  1206  and the color reaction is completed, the detection chip  1200  can be subsequently placed in the analyzer  1100 . 
     Step S 200 : opening the first shell and the second shell, and placing the detection chip. The opening distance (the second end portion  1194  of the first locking tongue  1183  and the second end portion  1195  of the second locking tongue  1184  are moved closer to the middle of the two) between the second end portion  1194  of the first locking tongue  1183  and the second end portion  1195  of the second locking tongue  1184  is reduced, the first end portion  1185  of the first locking tongue  1183  and the first end portion  1186  of the second locking tongue  1184  are separated from the locker  1188  in a state of being snapped with the locker  1188 , so that the first shell  1110  and the second shell  1160  of the analyzer  1100  are opened, and the detection chip  1200  is placed in the chip placement structure  1120 . The embodiments of the present disclosure are not limited to the sequence of step S 100  and step S 200 , for example, after that the detection chip  1200  is placed in the chip placement structure  1120 , the liquid to be detected is then dropped into the detection chip  1200 , which is not specifically limited herein. 
     Step S 300 : closing the first shell and the second shell, and turning on the analyzer for detection. Closing the first shell  1110  and the second shell  1160 , then long time pressing the micro-switch  1305   a , the analyzer  1100  starts to detect. The controller device  1310  receives the detection results of the photoelectric detector units  1131  and sends the detection results to the displayer device  1170 . 
     Step S 400 : obtaining the detection results. After the detection of the analyzer  1100  is completed, the detection results are checked by pressing the micro-switch  1305   b  on the display screen, the detection results such as detection reports are also possible to be sent to other devices via bluetooth (for example, pushing detection reports to software or applets used by users). 
     Step S 500 : retrieving the detection chip and turning off the analyzer. Turning on the first shell  1110  and the second shell  1160  of the analyzer  1100  again, taking the detection chip  1200  out, then the first shell  1110  and the second shell  1160  are closed, and short time pressing the micro-switch  1305   a  to turn off the analyzer  1100 . 
     The analyzer  1100  can measure the contents of various substances in liquid, such as breast milk, at the same time, the analyzer  1100  can display the detection results in a short period of time (for example, 2-3 minutes). The above-mentioned analyzer  1100  has the advantages of simple structure and convenient operation, and can be used as a small, hand-held home testing equipment, so that the users can complete the entire detection process at home, and the analyzer  1100  can realize real-time upload of detection results to, for example, the port of an application (APP) installed on a mobile terminal such as a mobile phone, and it is convenient to provide users with, such as the analysis of the substance content of breast milk, and to provide professional nutrition, dietary guidance and clinical advice based on the analysis results. 
     For the detection system and the analyzer in the above embodiments, because the detector unit of the analyzer includes a plurality of photoelectric detector units or at least one relatively rotatable photoelectric detector unit, the analyzer can detect the plurality of detection areas of the detection chip through the plurality of photoelectric detector units, so that the content of various substances in the liquid to be detected in the detection chip is detected. 
       FIG. 14  is still another schematic diagram of the analyzer provided by at least one embodiment of the present disclosure. The embodiments of the present disclosure further provide an analyzer, and the embodiments of the present disclosure may also be illustrated as shown in  FIG. 14 . 
     As shown in  FIG. 14 , the analyzer  3100  includes a detector module  3110  and a controller module  3130 . The detector module  3110  includes a chip placement structure  3120 . The detector module  3110  is configured to detect at least one detection area  1206  of the detection chip  1200  in the case where the detection chip  1200  (as shown in  FIG. 12B ) includes at least one detection area  1206  is placed on the chip placement structure  3120 . The controller module  3130  is connected in signal with the detector module  3110 , and is configured to control the detection operation of the detector module  3110  and receive the detection results of the detector module  3110 . 
     For example, in some examples, the chip placement structure  3120  is a space in which the detection chip  1200  is placed, and the detection chip  1200  can be shielded from ambient light in the case where the detection chip  1200  is detected. For example, the chip placement structure  3120  may be the structure as shown in  FIG. 2 , in the case where the detector module  3110  includes the first shell  1110  and the second shell  1160 , the chip placement structure  3120  is located in the first shell  1110 , for placing the detection chip  1200 . The first shell  1110  and the second shell  1160  can be opened and closed on one side, to facilitate the users to place and retrieve the detection chip  1200 , and in the case where the analyzer  3100  is working, the interference of external light on the detection of the detection chip is avoided. The chip placement structure  3120  is a lower “concave” accommodating space formed in the first shell  1110  from the opening (for example, the circular opening  1301   a  of the first shielding plate  1301  in  FIG. 2 ) in the upper surface (for example, formed by the surface of the first shielding plate  1301  in  FIG. 2 ) of the first shell  1110 . For example, a cross section of the accommodating space is substantially in a circular shape. It should be noted that, other shapes, such as rectangular, elliptical, etc., may also be adopted. In the case where the detector module  3110  only includes the first shell  1110 , the upper surface of the first shell  1110  is made into a plane that can shield light, an opening is arranged at the side of the first shell  1110 , and the opening is connected with the chip placement structure  3120 . An object stage can be added to the chip placement structure  3120 , the object stage can be ejected from the opening of the chip placement structure  3120  to place the detection chip  1200  on the object stage, and then the object stage is pushed into the chip placement structure  3120  to detect the detection chip  1200 . It should be noted that, a drawer type can be selected for the operation of the object stage, and the ambient light is shielded in the case where the detection chip  1200  is detected. 
     For example, in some examples, the controller module  3130  receives the electrical signals sent by the detector module  3110 , and obtains the detection results according to the electrical signals. For example, the controller device  3130  may include a processor and a memory, the processor may include a central processor unit (CPU), or a data processor (DSP), and the memory may include a semiconductor memory, which is configured to store computer codes for execution on the processor and to store data. 
       FIG. 15  is still another schematic diagram of the analyzer provided by at least one embodiment of the present disclosure. As shown in  FIG. 15 , the detector module  3110  includes at least one photoelectric detector unit  3131 . The at last one photoelectric detector unit  3131  may be of various types, for example, including but not limited to at lase one photoelectric detector unit  3131 . These photoelectric detector units  3131  are configured to detect the plurality of detection areas  1206  of the detection chip  1200  in the case where the detection chip  1200  is placed on the chip placement structure  3120 . 
     For example, in other examples, the detector module  3110  includes a plurality of photoelectric detector units  3131 , the plurality of photoelectric detector units  3131  correspond to the plurality of detection areas  1206  of the detection chip  1200  (for example, in the vertical direction, that is, in the axial direction of the first shell  1110 ) respectively. 
     For example, in some examples, each of the photoelectric detector unit  3131  includes at least one light-emitter element and at least one photoelectric sensor device. As shown in  FIG. 15 , each of the plurality of photoelectric detector units  3131  includes two light-emitter elements  3132  and a photoelectric sensor device  3133 . For example, the two photoelectric light-emitter elements  3132  (for example, symmetrical) are located at both sides of a photoelectric sensor device  3133 . The arrangement of two light-emitter elements  3132  and one photoelectric sensor device  3133  can ensure that the light emitted by the light-emitter element  3132  is evenly incident on corresponding detection area of the detection chip  1200 , and can also increase the intensity of the incident light provided by the two light-emitter elements  3132  and the intensity of the reflected light after being reflected by the detection chip  1200 , thereby improving the stability of analyzer detection. For example, light of a specific intensity (incident light) emitted by the light-emitter element  3132  is transmitted to the chip placement structure  3120  to reach the detection chip  1200  placed on the chip placement structure  3120 , then the light reflected by the plurality of detection areas  1206  (the detection sample in the plurality of detection areas  1206 ) of the detection chip  1200  is received by the photoelectric sensor device  3133 . The photoelectric sensor device  3133  will receive light signals (reflected light) and convert the light signals into electrical signals. The controller device  3130  can obtain the intensity of the light signal received by the photoelectric sensor device  3133  according to the electrical signals. 
     For example, in other examples, each of the plurality of photoelectric detector units  3131  may also include a photoelectric sensor device  3133  and a light-emitter element  3132 , and can also realize the detection of the liquid to be detected in the plurality of detection areas  1206  of the detection chip  1200 . Alternatively, each of the plurality of photoelectric detector units  3131  may also include the plurality of photoelectric sensor devices  3133  and the plurality of light-emitter elements  3132 , the plurality of photoelectric sensor devices  3133  can detect different substances in the liquid to be detected. The embodiments of the present disclosure are not limited by the number of light-emitter elements  3132  and the number of photoelectric sensor devices  3133 . 
     For example, in some examples, the light-emitter element  3132  includes a light-emitting diode (Light-emitting Diode, LED), the photoelectric sensor device  3133  includes a photo-diode (PD), such as a silicon photo-diode. The Light-emitting diode can emit light of specific wavelength (for example, infrared light, red light, green light, etc.), and the light-emitting diode of specific wavelength can be selected according to the type of substance to be detected. The wavelengths of light emitted by light-emitting diodes located in different photoelectric detector units  3131  are different, so that the plurality of photoelectric detector units  3131  can detect various substances. For example, a photoelectric detector unit  3131  can select a light-emitter element that emits light with a wavelength of 630 nm, which is configured to detect the content of lactose and fat in the liquid to be detected, and the maximum absorption peak of light with a wavelength of 630 nm can be obtained, so that the photoelectric detector unit  3131  obtains the maximum receiving efficiency, thereby improving the accuracy of detection. For example, the photoelectric detector unit  3131  can also select a light-emitter element that emits light with a wavelength of 660 nm, which is configured to detect the content of calcium and protein in the liquid to be detected, and the maximum absorption peak of light with a wavelength of 660 nm can be obtained, so that the photoelectric detector unit  3131  obtains the maximum receiving efficiency, thereby improving the accuracy of detection. The photoelectric detector unit  3131  can also select a light-emitter element that emits light with a wavelength of 585 nm, which is configured to detect the content of zinc in the liquid to be detected, and the maximum absorption peak of light with a wavelength of 585 nm can be obtained, so that the photoelectric detector unit  3131  obtains the maximum receiving efficiency, thereby improving the accuracy of detection. In this way, the photoelectric sensor device  3133  of the photoelectric detector unit  3131  of the analyzer  3100  provided in the embodiments of the present disclosure can generate at least five detection signals (for example, corresponding to lactose, fat, zinc, calcium, and protein, respectively). The detector module  3110  can transmit a plurality of detection signals to the controller module  3130 , the controller module  3130  processes the detection signals to obtain corresponding detection results, and the controller module  3130  may transmit the detection results to the displayer module  3170  (as shown in  FIG. 15 , the displayer module  3170  will be described in detail in the following) for display on the displayer module  3170 . Therefore, the analyzer  3100  provided by the embodiments of the present disclosure can detect a plurality of index items (such as the content of lactose, fat, zinc, calcium, and protein) at the same time. 
     For example, in some examples, as shown in  FIG. 15 , the analyzer  3100  further includes a light splitter component  3140 . The light splitter component  3140  is arranged between the chip placement structure  3120  and the at least one photoelectric detector unit  3131 , and is configured as that the light emitted by the at least one light-emitter element  3132  is transmitted to the chip placement structure  3120 , and the light reflected from the detection chip  1200  placed on the chip placement structure  3120  is transmitted to at least one photoelectric sensor device  3133 . As shown in  FIG. 6A , the light splitter component  3140  may include a light splitter disk  1141 . The light splitter disk  1141  includes at least one group of light through holes  1142 , and the at least one group of light through holes  1142  are evenly arranged on the same circumference of the light splitter disk  1141 . Each group of light through holes  1142  includes at least one light-emitting through hole and at least one light-reflecting through hole, the at least one light-emitting through hole allows the light emitted by the light-emitter element  3132  of the corresponding photoelectric detector unit  3131  to pass through, and the at least one light-reflecting through hole allows light reflected from the detection chip  1200  placed on the chip placement structure  3120  to pass through for transmission to the photoelectric sensor device  3133  of the corresponding photoelectric detector unit  3131 . Two light-emitting through holes  1143  are located at both sides of the light-reflecting through hole  1144 , the light-emitting through holes  1143  corresponds to the light-emitter elements  3132  in the photoelectric detector unit  3131 , and the light-reflecting through hole  1144  corresponds to the photoelectric sensor device  3133  in the photoelectric detector unit  3131 . The light emitted by the light-emitter elements  3132  passes through the light-emitting through hole  1143  and then is incident on the chip placement structure  3120 , and the light reflected from the detection chip  1200  placed on the chip placement structure  3120  passes through the light-reflecting through hole  1144  and then is received by the photoelectric sensor device  3133 . The arrangement of the light splitter disk  1141  can avoid the interference of light signals between different photoelectric detector units  3131  to ensure the reliability of the detection results. 
     It should be noted that, the light splitter disk  1141  is an example of the light splitter component  3140 , and the light splitter component  3140  can also be selected as other optical path structures, which is not limited in the embodiments of the present disclosure. 
     For example, in some examples, as shown in  FIG. 15 , the analyzer  3100  further includes a separator component  3150 . The separator component  3150  is arranged between the light splitter component  3140  and the chip placement structure  3120 . The separator component  3150  includes a light-transmitter portion. The light-transmitter portion is configured to allow the light emitted by the at least one light-emitter element  3132  and the light reflected from the detection chip  1200  placed on the chip placement structure  3120  to pass through. The separator component  3150  may include the separator component  1150  as shown in  FIG. 4A . The separator component  1150  includes a light-transmitter portion  1151 , which is configured to allow the light emitted by the light-emitter element  3132  of the photoelectric detector unit  3131  and the light reflected from the detection chip  1200  placed on the chip placement structure  3120  to pass through. The detection chip  1120  is located above the separator component  3150 , and the separator component  3150  is configured to prevent the penetration of the liquid to be detected in the plurality of detection areas of the detection chip  1120 , for example, the separator component  3150  can also provide protection functions for the optical path components below. The light-transmitter portion  1151  of the separator component  3150  includes at least one transparent window  1152 , which respectively correspond to the plurality of photoelectric detector units  3131 , so that the at least one transparent window  115  respectively allow the light emitted from the at least one light-emitter element  3132  of the corresponding photoelectric detector unit  3131  and the light reflected from the detection chip  1200  placed on the chip placement structure  3120  to the at least one photoelectric sensor device  3133  of the corresponding photoelectric detector unit  3131  to pass through. 
     For example, in some examples, as shown in  FIG. 15 , the analyzer  3100  further includes a displayer module  3170 . The displayer module  3170  is connected in signal with the controller module  3130 , and is configured to receive the detection results of the detector module  3110  sent by the controller module  3130  and to display the detection results of the detector module  3110 . The displayer module  3170  may include, for example, a liquid crystal displayer device, an organic light-emitting diode (OLED) displayer device, electronic paper, a digital tube, etc., for displaying the detection results of the analyzer  3100 . In the case where the analyzer  3100  includes the second shell  1160  or the first shell  1110  (as shown in  FIG. 1 ), the displayer module  3170  may be arranged at the second shell  1160  or the first shell  1110 . 
     For example, in some examples, as shown in  FIG. 15 , the analyzer  3100  further includes a switch module  3160 . The switch module  3160  is connected in signal with the displayer module  3170 , and is configured to control the content displayed on the displayer module  3170 . The switch module  3160  can also realize the switch function of the analyzer  3100 . For example, as shown in  FIG. 9 , the switch module  3160  can include a micro-switch  1305   a  and a micro-switch  1305   b  or one of the micro-switch  1305   a  and the micro-switch  1305   b , which realizes the switch function of the analyzer  3100  and the function of controlling the display of the detection results on the displayer module  3170 . For example, long time pressing the micro-switch  1305   a  to turn on the analyzer  1100 , and to start the detection of the detection chip  1200 , short time pressing the micro-switch  1305   a  to turn off the analyzer. The display contents of the displayer module  3170  is controlled by pressing the micro-switch  1305   b , and the detection results can be viewed on the displayer module  3170  according to the selection. 
     For example, in some examples, as shown in  FIG. 15 , the analyzer  3100  further includes a signal transmitter and receiver device  3180 .
