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.

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>, the chip placement structure <NUM> is a space composed of the opening 1301a of the first shielding plate <NUM>, an inner sidewall of the light splitter disk <NUM>, and an upper surface (as shown in <FIG>) of a separator component <NUM> (as shown in <FIG>).

An object stage can be added on the chip placement structure <NUM>, the object stage can be ejected from the opening of the chip placement structure <NUM> to place the detection chip <NUM> on the object stage, and then the object stage is pushed into the chip placement structure <NUM> to detect the detection chip <NUM>. 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 <NUM> is detected. The embodiments of the present disclosure is not limited by the shape and the structure of the second shell <NUM>.

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 <NUM>. For another example, a plurality of fulcrums may be arranged at the side wall of the chip placement structure <NUM>, the detection chip <NUM> 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 <NUM> is placed on the chip placement structure <NUM>, the plurality of fulcrums cooperate with the notches of the detection chip <NUM> to stably place the detection chip <NUM>. For another example, a clamping mechanism may be arranged at the side wall of the chip placement structure <NUM>, the detection chip <NUM> is stably placed in the chip placement structure <NUM> by the clamping mechanism. For another example, the chip placement structure <NUM> may also include a platform that can be raised and lowered to put the detection chip <NUM> 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 <NUM>. It should be noted that, the detection chip <NUM> 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 <NUM> 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> is another schematic diagram of the analyzer provided by at least one embodiment of the present disclosure. As shown in <FIG>, the first shell <NUM> includes a first supporter portion <NUM> and a second supporter portion <NUM>. For example, the first supporter portion <NUM> and the second supporter portion <NUM> are arranged symmetrically with respect to a center line of the first shell <NUM>. The first supporter portion <NUM> and the second supporter portion <NUM> are arranged at the bottom of the first shell <NUM>, 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 <NUM> on a plane is provided, and the first shell <NUM> is prevented from tilting to cause a relative positional relationship between the internal structures of the analyzer <NUM> to shift.

<FIG> is a structural schematic diagram of a lower portion of the analyzer provided by at least one embodiment of the present disclosure; <FIG> 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> 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>, and <FIG>, the lower portion of the analyzer <NUM> includes a first shell <NUM> and a chip placement structure <NUM>. The detection chip <NUM> includes a plurality of detection areas, and the detailed structure of the detection chip <NUM> can refer to <FIG>, <FIG> described in the following. In the examples in the figures, the chip placement structure <NUM> provides a chamber for accommodating and supporting the detection chip <NUM> and the chamber has substantially the same cross-sectional shape as the detection chip <NUM>. For example, a circular chamber is shown in the figures, the chip placement structure <NUM> 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 <NUM> further includes a detector unit for detecting the inserted detection chip <NUM>. 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 <NUM>. In the following descriptions, the photoelectric detector units are taken as an example for description. As shown in <FIG>, 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 <NUM>. These photoelectric detector units <NUM> are configured to detect the plurality of detection areas of the detection chip <NUM> in the case where the detection chip <NUM> is placed on the chip placement structure <NUM>, and specific exemplary descriptions are as follows. For example, a notch can be arranged in a circumferential direction of the detection chip <NUM>, and the shape of the notch is the same as the shape of the limiter block of the chip placement structure <NUM>, so that in the case where the detection chip <NUM> is placed on the chip placement structure <NUM>, the notch of the detection chip <NUM> is sleeved at the limiter block, and the detection areas of the detection chip <NUM> and the photoelectric detector units <NUM> are aligned in a direction perpendicular to the photoelectric detector units <NUM>, thereby allowing the user to place the detection chip <NUM> on the chip placement structure <NUM> 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 <NUM> to align with the detection chip <NUM>. The embodiments of the present disclosure are not limited to this.

In some embodiments, an outer surface of the first shell <NUM> is approximately in a semi-spherical shape, the chip placement structure <NUM> is located in the first shell <NUM> close to the upper side of the first shell <NUM> to facilitate the insertion of the detection chip. The chip placement structure <NUM> includes a first shielding plate <NUM>, the first shielding plate <NUM> is connected with the upper side of the first shell <NUM>, for example, by a method of snap connection, or a method of screw connection. An opening 1301a is arranged at a center of the first shielding plate <NUM> to form a space for placing the detection chip <NUM> in the first shell <NUM> to provide an accommodation chamber. The first shielding plate <NUM> can shield other stray light outside the first shell <NUM> to avoid interference of other light rays on the detection result. For example, the accommodation chamber of the chip placement structure <NUM> is in a cylindrical shape to match the shape of the detection chip <NUM>. 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 <NUM> 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>, the lower portion of the analyzer <NUM> further includes a detection circuit board <NUM>, the detection circuit board <NUM> is arranged under the chip placement structure <NUM> in the first shell <NUM>. The detector unit is arranged on the detection circuit board <NUM> and corresponds to the detection chip <NUM> in an axial direction of the first shell <NUM>. The detector unit includes a plurality of photoelectric detector units <NUM>, the plurality of photoelectric detector units <NUM> respectively correspond to the plurality of detection areas of the detection chip in the axial direction of the first shell <NUM>.

For example, as shown in <FIG>, a plurality of photoelectric detector units <NUM> are evenly arranged on a same circumference to respectively detect the plurality of detection areas of the detection chip <NUM>, for example, to detect the plurality of detection areas of the detection chip <NUM> at the same time, or to detect the plurality of detection areas of the detection chip <NUM> in a certain order, so that the contents of various substances in the liquid to be detected in the detection chip <NUM> are detected. With the structure design that the plurality of photoelectric detector units <NUM> 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 <NUM> are arranged on the same circumference, the plurality of corresponding photoelectric detector units <NUM> are evenly arranged on the same circumference. In the case where the plurality of detection areas of the detection chip <NUM> are arranged on the same circumference, and in the case where a sample is injected from the center of the detection chip <NUM>, 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 <NUM> 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 <NUM> 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 <NUM>.

For example, in some examples, each of the plurality of photoelectric detector units <NUM> includes at least one light-emitter element and at least one photoelectric sensor device. In an example as shown in <FIG>, the plurality of photoelectric detector units <NUM> respectively includes two photoelectric light-emitter elements <NUM> and a photoelectric sensor device <NUM>. The two photoelectric light-emitter elements <NUM> (for example, are symmetrical) are located at two sides of the photoelectric sensor device <NUM>. For example, a distance between two adjacent photoelectric light-emitter elements <NUM> located in different photoelectric detector units <NUM> is greater than a distance between the photoelectric light-emitter element <NUM> and the photoelectric sensor device <NUM> in a same photoelectric detector unit <NUM>, so that interference of light signals between different photoelectric detector units <NUM> is avoided. The arrangement of two photoelectric light-emitter elements <NUM> and one photoelectric sensor device <NUM> can ensure that the light emitted by the light-emitter elements <NUM> is evenly incident on the detection areas of the detection chip <NUM>, and the arrangement can also increase the intensity of the incident light provided by the two light-emitter elements <NUM> and the intensity of the reflected light after being reflected by the detection chip <NUM>, and then the detection stability of the analyzer is improved.

For example, the distance between two adjacent light-emitter elements <NUM> in different photoelectric detector units <NUM>, for example, a linear distance between centers of two adjacent light-emitter elements <NUM> ranges from <NUM> to <NUM>. For another example, in <FIG>, the linear distance between the centers of two adjacent light-emitter elements <NUM> is about <NUM>. For example, in the same photoelectric detector unit <NUM>, a linear distance between a center of one of the two light-emitter elements <NUM> and a center of the photoelectric sensor device <NUM> ranges from <NUM> to <NUM>. For another example, in <FIG>, the linear distance between the center of one of the two light-emitter elements <NUM> and the center of the photoelectric sensor device <NUM> is about <NUM>. For example, the distance between the centers of two adjacent photoelectric detector units <NUM> on the circumference ranges from <NUM> to <NUM>. For another example, in <FIG>, the distance between the centers of two adjacent photoelectric detector units <NUM> on the circumference is <NUM>. It should be noted that, the word "about" means that the value can be varied within, for example, ±<NUM>% of the value.

For example, in some examples, as shown in <FIG>, for example, the number of the plurality of photoelectric detector units <NUM> is six. For another example, the number of the photoelectric detector units <NUM> can also be two, three, four, five, seven, etc., the number is determined according to the number of detection areas of the detection chip <NUM>, and the embodiments of the present disclosure are not limited by the number of the plurality of photoelectric detector units <NUM>.

For example, in other examples, the plurality of photoelectric detector unit <NUM> respectively may also include a photoelectric sensor device <NUM> and a light-emitter element <NUM>, and the detection of the liquid to be detected in the detection area of the detection chip <NUM> can also be realized. Alternatively, the photoelectric detector unit <NUM> may also include a plurality of photoelectric sensor devices <NUM> and a plurality of light-emitter elements <NUM>, the plurality of photoelectric sensor devices <NUM> 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 <NUM> and the number of the photoelectric sensor devices <NUM>.

For example, the arrangements of the plurality of the photoelectric sensor devices <NUM> and the plurality of the light-emitter elements <NUM> of the photoelectric detector unit <NUM> can be flexibly changed according to the requirements of the detection index of the liquid to be detected of the detection chip <NUM>. For example, the plurality of the light-emitter elements <NUM> surround the photoelectric sensor device <NUM> in a manner of providing the moon with stars, or the plurality of the light-emitter elements <NUM> are arranged in two rows at both sides of the photoelectric sensor device <NUM>.

<FIG> 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>, the light-emitter elements <NUM> are configured to generate light signals, a specific intensity light (incident light) emitted by the light-emitter elements <NUM> is transmitted to the chip placement structure <NUM> to reach the detection chip <NUM> placed on the chip placement structure <NUM>, and then the light reflected by the detection areas (the detection sample in the detection chip <NUM>) of the detection chip <NUM> is received by the photoelectric sensor device <NUM>. The photoelectric sensor device <NUM> 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 <NUM> can be obtained.

For example, in other examples, the light-emitter element <NUM> may also be arranged as one light-emitter element <NUM>, that is, the light emitted by the one light-emitter element <NUM> illuminates the detection areas of the detection chip <NUM> as incident light. The detection principle of the embodiment of the present disclosure is not limited by the number of the light-emitter elements <NUM>.

An absorbance value of the liquid to be detected is calculated according to the following formula:
<MAT>.

In the above formula, I<NUM> 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 <NUM>, 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 <NUM>, 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 (<NUM>).

For example, in some examples, the light-emitter elements <NUM> and the photoelectric sensor device <NUM> of the analyzer <NUM> need to be calibrated to ensure the stability of the light source of the analyzer <NUM>. A standard gray scale plate is configured to calibrate the light emitted by the light-emitter elements <NUM> of the analyzer <NUM>. 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 <NUM> detects the standard gray scale plate, is compared with the standard absorbance value, and the light emitted by the light-emitter elements <NUM> of the analyzer <NUM> 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 <NUM> 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>, for example, at points D1, D2, D3, D4 and D5, 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> 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>, 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 <NUM>, the contents of various substances in the liquid to be detected are obtained.

For example, in some examples, the light-emitter elements <NUM> include light-emitting diodes (LEDs), the photoelectric sensor devices <NUM> 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 <NUM> are different, so that detecting various substances can be realized by using the plurality of the photoelectric detector units <NUM>. For example, a photoelectric detector unit <NUM> can select light-emitter elements that emit light with a wavelength of <NUM>, 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 <NUM> can be obtained, so that the photoelectric detector unit <NUM> obtains the maximum receiving efficiency, thereby improving the accuracy of detection. For example, the photoelectric detector unit <NUM> can also select light-emitter elements that emit light with a wavelength of <NUM> 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 <NUM> can be obtained, so that the photoelectric detector unit <NUM> obtains the maximum receiving efficiency, thereby improving the accuracy of detection. The photoelectric detector unit <NUM> can also select light-emitter elements that emit light with a wavelength of <NUM> to detect the content of zinc in the liquid to be detected, and a maximum absorption peak of light with the wavelength of <NUM> can be obtained, so that the photoelectric detector unit <NUM> obtains the maximum receiving efficiency, thereby improving the accuracy of detection. Therefore, the photoelectric sensor device <NUM> of the photoelectric detector unit <NUM> of the analyzer provided by the embodiments of the present disclosure can generate at least <NUM> 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 <NUM>, 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 <NUM> further includes an optical path component, the optical path component is arranged in the first shell <NUM> between the chip placement structure <NUM> and the detector unit, and is configured to transmit the light emitted by at least one light-emitter element <NUM> to the chip placement structure <NUM>, and to transmit the light reflected from the detection chip <NUM> placed on the chip placement structure <NUM> to at least one photoelectric sensor device <NUM>. The optical path component can avoid the interference of light signals between different photoelectric detector units <NUM>, so that the reliability of the detection results is ensured.

For example, in some examples, as shown in <FIG> and <FIG>, the optical path component includes a light splitter disk <NUM>, which is arranged on the detector unit. The light splitter disk <NUM> includes at least one group of light through holes <NUM>, the at least one group of light through holes <NUM> are evenly arranged on the same circumference of the light splitter disk <NUM>, and correspond to a plurality of photoelectric detector units <NUM> in a direction along an axis of the first shell <NUM> respectively.

For example, in the present example, as shown in <FIG>, for example, the number of groups of light through holes <NUM> is six. For another example, the number of groups of the light through holes <NUM> may also be two, three, four, five, seven, etc., which corresponds to the number of the photoelectric detector units <NUM>. The embodiments of the present disclosure are not limited to the number of groups of the light through holes <NUM>.

For example, in some examples, each group of light through holes <NUM> 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 <NUM> of the corresponding photoelectric detector unit <NUM> to pass through, the at least one light-reflecting through hole allows the light reflected from the detection chip <NUM> placed on the chip placement structure <NUM> to pass through so as to transmit to the photoelectric sensor device <NUM> of the corresponding photoelectric detector unit <NUM>. As shown in <FIG>, each group of light through holes <NUM> includes two light-emitting through holes <NUM> and one light-reflecting through hole <NUM>. The two light-emitting through holes <NUM> are located at both sides of the light-reflecting through hole <NUM>, the light-emitting through holes <NUM> correspond to the light-emitter elements <NUM> in the photoelectric detector unit <NUM>, and the light-reflecting through hole <NUM> corresponds to the photoelectric sensor device <NUM> in the photoelectric detector unit <NUM>. The light emitted by the light-emitter elements <NUM> passes through the light-emitting through holes <NUM> and then is incident on the chip placement structure <NUM>, the light reflected from the detection chip <NUM> placed on the chip placement structure <NUM> passes through the light-reflecting through hole <NUM> and then is received by the photoelectric sensor device <NUM>. The arrangement of the light splitter disk <NUM> can avoid the interference of light signals between different photoelectric detector units <NUM>, so that the reliability of the detection results is ensured.

For example, in some examples, as shown in <FIG>, the side wall of each of the light-emitting through holes <NUM> of each group of light through holes <NUM> is an inclined surface, the opening of each of the light-emitting through holes <NUM> on the side facing away from the photoelectric detector units <NUM> is larger than the opening of each the light-emitting through holes <NUM> at the side close to the photoelectric detector units <NUM>, so that the irradiation area of the light emitted by the light-emitter elements <NUM> on the detection chip <NUM> can be increased. An angle between the side wall of each of the light-emitting through holes <NUM> and an X direction (perpendicular to the axial direction of the light splitter disk <NUM>) is α. The value range of the included angle α is, for example, from about <NUM> degrees to about <NUM> degrees, for another example, the value of the included angle α is about <NUM> degrees, so that the incident light passing through the light-emitting through holes <NUM> is emitted along the inclined surface of the long side of the light-emitting through holes <NUM>, the light can be better concentrated in the detection areas of the detection chip <NUM>, and a divergence of the incident light is reduced.

For example, the side wall of the light-reflecting through hole <NUM> of each group of light through holes <NUM> is an inclined surface, the opening of the light-reflecting through hole <NUM> on the side facing away from the photoelectric detector units <NUM> is larger than the opening of the light-reflecting through hole <NUM> at the side close to the photoelectric detector units <NUM>, so that the interference between the light emitted by the light-emitter elements <NUM> and the light reflected from the detection chip <NUM> placed on the chip placement structure <NUM> can be avoided. The angle between the side wall of the light-reflecting through hole <NUM> and the X direction (perpendicular to the axial direction of the light splitter disk <NUM>) is β. The value range of the included angle β is, for example, from about <NUM> degrees to <NUM> degrees, for another example, the value of the included angle β is about <NUM> degrees. It should be noted that, the word "about" means that the value can be varied within, for example, ±<NUM>% of the value.

For example, in some examples, the light-emitting through holes <NUM> include, for example, rectangular holes as shown in <FIG>. The size range of the opening of each of the light-emitting through holes <NUM> at the side close to the photoelectric detector units <NUM> in a circumferential direction and a radial direction is, for example, from about <NUM> to <NUM>. For another example, the size of each of the light-emitting through holes <NUM> in both the circumferential direction and the radial direction is, for example, about <NUM>. The light-reflecting through hole <NUM> include, for example, a circular hole as shown in <FIG>, and the value range of the diameter of the light-reflecting through hole <NUM> is, for example, from about <NUM> to about <NUM>. For another example, the size of the opening of the light-reflecting through hole <NUM> at the side close to the photoelectric detector unit <NUM> in the circumferential direction, for example, is about <NUM>. It should be noted that, the word "about" means that the value can be varied within, for example, ±<NUM>% of the value. For another example, both the size of the light-emitting through holes <NUM> and a diameter of the light reflecting through hole <NUM> can be selected to be slightly larger than <NUM> according to the requirements of processing, so long as there is no optical crosstalk between two adjacent group of light through holes <NUM>. The embodiments of the present disclosure is not limited by the specific size of the light-emitting through holes <NUM> and the light reflecting through hole <NUM>.

For example, in some examples, as shown in <FIG>, the value range of a long side of the light-emitting through hole <NUM> is, for example, from about <NUM> to about <NUM>, for another example, the value of the long side of the light-emitting through hole <NUM> is about <NUM>. The value range of a short side of the light-emitting through hole <NUM> is, for example, from about <NUM> to about <NUM>, for another example, the value of the short side of the light-emitting through hole <NUM> is about <NUM>. It should be noted that, the word "about" means that the value can be varied within, for example, ±<NUM>% of the value. The light-emitting through holes <NUM> include rectangular holes, so that the incident light passing through the light-emitting through holes <NUM> is emitted along the inclined surfaces of the long side of the light-emitting through hole <NUM>, the light can be better concentrated in the detection areas of the detection chip <NUM>, and the divergence of the incident light is reduced.

<FIG> 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>. As shown in <FIG>, the light-reflecting through hole <NUM> includes a first reflecting through sub-hole 1144b close to the first side of the light splitter disk <NUM> (a lower side in the figure, that is, the side where the incident light enters), and a second reflecting through sub-hole 1144a close to the second side of the light splitter disk <NUM> (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 1144b is smaller than the diameter of the second reflecting through sub-hole 1144a, so that the light emitted from the light-emitting through holes <NUM> 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 1144b is, for example, from about <NUM> to about <NUM>. For another example, the size of the diameter of the first reflecting through sub-hole 1144b is, for example, about <NUM>. For example, the size range of the diameter of the second reflecting through sub-hole 1144a is, for example, from about <NUM> to about <NUM>. For another example, the size of the diameter of the second reflecting through sub-hole 1144a is, for example, about <NUM>. It should be noted that, the word "about" means that the value can be varied within, for example, ±<NUM>% of the value. Thus, the light emitted from the light-emitting through holes <NUM> 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 1144b is not reflected.

For another example, as shown in <FIG>, an upper surface (for example, the surface close to the second side) of the light splitter disk <NUM> includes at least one protrusion 1144c. The protrusion 1144c protrudes obliquely from the side of the two light-emitting through holes <NUM> close to the light-reflecting through hole <NUM> to the second side in the direction close to the light-reflecting through hole <NUM>. The first reflecting through sub-hole 1144b is located in the protrusion 1144c, so that the light emitted from the light-emitting through holes <NUM> can be shielded from entering the light-emitting through holes, and causing detection errors is avoided.

For another example, as shown in <FIG>, the protrusion 1144c is in an annular shape, the protrusion 1144c surrounds the first reflecting through sub-hole 1144b. The light emitted from the light-emitting through holes <NUM> can be shielded from entering the light-emitting through holes, and causing detection errors is avoided.

For example, as shown in <FIG>, the value range of the slope angle γ of the protrusion 1144c is, for example, from about <NUM>° to about <NUM>°, for another example, the value of the slope angle γ of the protrusion 1144c is, for example, about <NUM>°. For example, the value range of the height of the protrusion 1144c protruding from the light-emitting through holes <NUM> is, for example, from about <NUM> to about <NUM>, for another example, the height of the protrusion 1144c protruding from the light-emitting through holes <NUM> is, for example, about <NUM>. For example, it should be noted that the word "about" means that the value can vary within, for example, ±<NUM>% of the value. Therefore, the inclined surface provided by the protrusion 1144c can shield the light emitted from the light-emitting through holes <NUM> for the first reflecting through sub-hole 1144b.

For example, in other examples, the shapes of the light-emitting through holes <NUM> can also include a triangle shape, a circle shape, and a polygonal shape, etc., the shape of the light-reflecting through hole <NUM> 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 <NUM> and the shape of the light-reflecting through hole <NUM>.

For example, in some examples, the light splitter disk <NUM> further includes at least one second positioning hole. As shown in <FIG>, the light splitter disk <NUM> includes three second positioning holes <NUM>, which are evenly distributed on a same circumference. The number of the second positioning holes <NUM> may also be two, four, etc., which is not limited in the embodiments of the present disclosure. As shown in <FIG>, first positioning holes <NUM> of the detection circuit board <NUM> are provided at a positions of the detection circuit board <NUM> opposite to the second positioning holes <NUM> of the light splitter disk <NUM>. The first positioning holes <NUM> of the detection circuit board <NUM> and the second positioning holes <NUM> are configured to install and position of both the light splitter disk <NUM> and the detection circuit board <NUM>, so that the photoelectric detector units <NUM> corresponds to the light through holes <NUM>.

For example, in some examples, as shown in <FIG> and <FIG>, the light splitter disk <NUM> further includes a limiter block <NUM>, and the limiter block <NUM> is arranged at the edge of the light splitter disk <NUM>. The limiter block <NUM> extends into the chip placement structure <NUM> to match the shape of the detection chip <NUM>. In the case where the detection chip <NUM> is placed in the chip placement structure <NUM>, the position of the detection chip <NUM> is fixed, so that the plurality of detection areas of the detection chip <NUM> correspond to the light through holes <NUM> of the light splitter disk <NUM> and the photoelectric detector units <NUM> respectively.

For example, in other examples, the limiter block <NUM> may also be arranged on other structures of the analyzer <NUM>, such as the first shielding plate <NUM>. For another example, the limiter block <NUM> can also be replaced with other structures that can achieve alignment with the detection chip <NUM>, which is not limited in the embodiments of the present disclosure.

For example, in other embodiments, the limiter block <NUM> can also be replaced by a positioning pin or a positioning hole, and a corresponding matching structure is arranged on the detection chip <NUM>.

For example, in some examples, as shown in <FIG>, the lower portion of the analyzer <NUM> further includes a separator component <NUM>, such as, a partition plate, which is located in the first shell <NUM> and is arranged between the optical path component and the chip placement structure <NUM>. That is, the separator component <NUM> is located above the optical path component and below the chip placement structure <NUM>. The separator component <NUM> includes a light-transmitter portion <NUM>, which is configured to allow the light emitted by the light-emitter elements <NUM> of the photoelectric detector units <NUM> and the light reflected from the detection chip <NUM> placed on the chip placement structure <NUM> to pass through. The detection chip <NUM> is located above the separator component <NUM>, and the separator component <NUM> is configured to prevent the penetration of the liquid to be detected in the detection areas of the detection chip <NUM>. For example, the separator component <NUM> can also provide protection functions for the optical path components arranged below. In other examples, the separator component <NUM> arranged at the lower portion of the analyzer <NUM> can be disassembled for easy replacement.

For example, in some examples, as shown in <FIG>, the light-transmitter portion <NUM> of the separator component <NUM> includes at least one transparent window <NUM>, which respectively corresponds to the plurality of photoelectric detector units <NUM>, and respectively allows the light emitted from the at least one light-emitter element <NUM> of the corresponding photoelectric detector unit <NUM> and the light reflected from the detection chip <NUM> placed on the chip placement structure <NUM> to the at least one photoelectric sensor device <NUM> of the corresponding photoelectric detector unit <NUM> to pass through.

For example, in the example, as shown in <FIG>, the number of the group of the transparent windows <NUM> is, for example, six. For another example, the number of the group of the transparent windows <NUM> can also be two, three, four, five, seven, etc., which corresponds to the number of the group of the light through holes <NUM>. The embodiments of the present disclosure is not limited by the number of the group of the transparent windows <NUM>.

For example, in some examples, as shown in <FIG>, each of the transparent windows <NUM> includes a first through hole <NUM>, a first groove <NUM>, and a transparent sheet <NUM>. The diameter of the first through hole <NUM> is smaller than the diameter of the first groove <NUM>, the first groove <NUM> is located at a side of the separator component <NUM> close to the chip placement structure <NUM>, and the first groove <NUM> is configured to place the transparent sheet <NUM>. The transparent sheet <NUM> is placed in the first groove <NUM>, which allows the light emitted by the two light-emitter elements <NUM> of the corresponding photoelectric detector unit <NUM> and the light reflected from the detection chip <NUM> placed on the chip placement structure <NUM> to the photoelectric sensor device <NUM> of the corresponding photoelectric detector unit <NUM> to pass through.

For example, the value range of the diameter of the transparent sheet <NUM> is, for example, from about <NUM> to about <NUM>, for another example, the value of the diameter of the transparent sheet <NUM> is, for example, about <NUM>. For example, the value range of the thickness of the transparent sheet <NUM> is, for example, from about <NUM> to about <NUM>, for another example, the thickness of the transparent sheet <NUM> is, for example, about <NUM>. The smaller the thickness of the transparent sheet <NUM>, 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 <NUM> is, for example, from about <NUM> to about <NUM>, for another example, the value of the diameter of the first through hole <NUM> is, for example, about <NUM>. It should be noted that, the word "about" means that the value can be varied within, for example, ±<NUM>% of the value. Therefore, the value of the diameter of the first through hole <NUM> can allow the light incident from the light-emitting through holes <NUM> on both sides of the light-reflecting through hole <NUM> better converge in the detection areas of the detection chip <NUM>, so that the divergence of incident light is reduced, and the detection accuracy is improved.

For example, in some examples, the transparent sheet <NUM> may include a glass sheet or a transparent acrylic sheet, etc..

For example, in other examples, the light-transmitter portion <NUM> may also be other light-transmitting structures, for example, a structure formed by a light-transmitting hole and the transparent sheet <NUM>, or a structure formed by removing the transparent sheet <NUM> in the transparent window <NUM>. The embodiments of the present disclosure are not limited by the specific structure of the light-transmitter portion <NUM>.

For example, in other examples, the separator component <NUM> may also be an overall transparent structure without arranging the transparent window <NUM>. For example, the separator component <NUM> is made of transparent material, so that the separator component <NUM> may allow the light emitted by the light-emitter elements <NUM> of the photoelectric detector unit <NUM> and the light reflected from the detection chip <NUM> placed on the chip placement structure <NUM> to the photoelectric sensor device <NUM> of the corresponding photoelectric detector unit <NUM> to pass through, and leakage of the liquid to be detected in the detection chip <NUM> is prevent. The embodiments of the present disclosure are not limited to this.

In some other examples, the separator component <NUM> may not be included, transparent windows are provided on the light through holes of the light splitter disk <NUM>, under this case, the light splitter disk <NUM> can also prevent the penetration of the liquid to be detected in the detection areas of the detection chip <NUM>.

For example, in some examples, as shown in <FIG>, the separator component <NUM> further includes a plurality of positioning columns <NUM>, which are arranged on a side of the separator component <NUM> close to the light splitter disk <NUM>. For another example, the separator component <NUM> includes three positioning columns <NUM>, the three positioning columns <NUM> correspond to the positioning holes <NUM> of the light splitter disk <NUM> and the positioning holes <NUM> of the detection circuit board <NUM>. In addition, the positioning columns <NUM> of the separator component <NUM> are installed in the positioning holes <NUM> of the light splitter disk <NUM> and the positioning holes <NUM> of the detection circuit board <NUM>, so that the separator component <NUM>, the light splitter disk <NUM> and the detection circuit board <NUM> are fixed, and the light-transmitter portion <NUM> of the separator component <NUM>, the light through hole <NUM> of the light splitter disk <NUM>, and the photoelectric detector unit <NUM> correspond with each other in an axial direction of the first shell <NUM>.

For example, in other examples, the second positioning holes <NUM> are arranged at the separator component <NUM>, the positioning columns <NUM> are arranged at the light splitter disk <NUM>, the positioning columns <NUM> extend to the upper side and the lower side of the light splitter disk <NUM>, the positioning columns <NUM> can also be installed in the positioning holes <NUM> of the light splitter disk <NUM> and the positioning holes <NUM> of the detection circuit board <NUM>, so that the separator component <NUM>, the light splitter disk <NUM>, and the detection circuit board <NUM> are fixed. The embodiments of the present disclosure is not limited by the installation method of the separator component <NUM>, the light splitter disk <NUM>, and the detection circuit board <NUM>.

For example, in other examples, other methods can also be used to fix the separator component <NUM>, the light splitter disk <NUM>, and the detection circuit board <NUM>, for example, using double-sided adhesive tape, or using lockers, etc..

For example, in some examples, as shown in <FIG>, the analyzer <NUM> further includes a second shell <NUM>, and the second shell <NUM> is connected to the first shell <NUM>. The chip placement structure <NUM> and the detector unit are arranged in a space enclosed by the first shell <NUM> and the second shell <NUM>. For example, in the present embodiment, the detector unit as shown in <FIG> is arranged on the detection circuit board <NUM> and are located in the first shell <NUM>. The first shell <NUM> and the second shell <NUM> are connected with each other at a first side <NUM>, and the first shell <NUM> and the second shell <NUM> can be relatively closed and opened at a second side <NUM>, so that the detection chip <NUM> is placed on the chip placement structure <NUM>, or the detection chip <NUM> is taken out from the chip placement structure <NUM>. It should be noted that, in the example as shown in the figure, the first side <NUM> is a side that the first shell <NUM> and the second shell <NUM> are connected with each other, the second side <NUM> is a side that the first shell <NUM> and the second shell <NUM> are relatively opened and closed, that is, the side that the detection chip <NUM> is placed, the first side <NUM> is arranged opposite to the second side <NUM>, and the relative positions of the first side <NUM> and the second side <NUM> do not constitute a limitation to the embodiments of the present disclosure. The first shell <NUM> is approximately in a hemispherical shape, and the shape of the opening below the first shell <NUM> is the same as the shape of the opening above the second shell <NUM>, so that a closed space that outside ambient light cannot be entered is formed in the case where the first shell <NUM> and the second shell <NUM> are closed to facilitate the detection of the analyzer <NUM>.

For example, in other examples, the shape of the second shell <NUM> may also be, for example, a cuboid, an opening shape of the second shell <NUM> and an opening shape of the first shell <NUM> 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> and <FIG>, the second shell <NUM> and the first shell <NUM> are hinged. The second shell <NUM> is configured to be closed with the first shell <NUM> at the second side <NUM>, and to be opened to expose the chip placement structure <NUM>. The first side <NUM> and the second side <NUM> are arranged opposite to each other.

For example, in some examples, as shown in <FIG>, the first shell <NUM> and the second shell <NUM> are hinged at the first side <NUM> by a hinge shaft <NUM>. A spring (such as a torsion spring) can also be arranged at the hinge shaft <NUM>, so that after the first shell <NUM> and the second shell <NUM> are opened at the second side, the second shell <NUM> will tilt up under the elastic force of the spring.

For example, in some examples, as shown in <FIG>, the second shell <NUM> further includes a second shielding plate <NUM> that connected with the lower side of the second shell <NUM>, for example, a snap connection, and a screw connection and so on. The second shielding plate <NUM> and the first shielding plate <NUM> in the first shell <NUM> form an accommodating space together for the detection chip. The second shielding plate <NUM> can shield other stray light in the second shell <NUM> to avoid interference of other light on the detection result.

For example, in some examples, as shown in <FIG> and <FIG>, the first shell <NUM> includes a first opening and closing sub-component <NUM> arranged at the second side <NUM>, the second shell <NUM> includes a second opening and closing sub-component <NUM> arranged at the second side <NUM>. The first opening and closing sub-component <NUM> and the second opening and closing sub-component <NUM> are configured to be combined with each other and separated from each other, so that the first shell <NUM> and the second shell <NUM> can be closed and opened with each other, respectively. In the case where the first shell <NUM> and the second shell <NUM> are opened, the detection chip <NUM> is placed on the chip placement structure <NUM>, after that, the first shell <NUM> and the second shell <NUM> are closed, and then the substance detection is started.

As shown in <FIG>, <FIG> and <FIG>, the second opening and closing sub-component <NUM> includes a first locking tongue <NUM> with a long strip shape and a second locking tongue <NUM> with a long strip shape, the first locking tongue <NUM> and the second locking tongue <NUM> are paired and arranged substantially side by side in the second shell <NUM>. The first locking tongue <NUM> and the second locking tongue <NUM> may be fixed on the second shielding plate <NUM>. The fixing method is, for example, a screw connection. A first end portion <NUM> of the first locking tongue <NUM> and a first end portion <NUM> of the second locking tongue <NUM> are exposed from the second shielding plate <NUM>. The first opening and closing sub-component <NUM> includes a groove <NUM> and a locker <NUM>, and the locker <NUM> is located in the groove <NUM>. The first end portion <NUM> of the first locking tongue <NUM> and the first end portion <NUM> of the second locking tongue <NUM> are configured to extend into the groove <NUM> and be snapped with the locker <NUM>, so that the first shell <NUM> and the second shell <NUM> can be closed and can be detached from the locker, thus the first shell <NUM> and the second shell <NUM> are opened.

For example, in some examples, as shown in <FIG>, the analyzer <NUM> further includes a fixing component <NUM>, a middle portion of the first locking tongue <NUM> and a middle portion of the second locking tongue <NUM> are fixed at the second shielding plate <NUM> by the fixing component <NUM>.

For example, in some examples, the second opening and closing sub-component <NUM> further includes an elastic component, the elastic component is arranged in both the middle portion of the first locking tongue <NUM> and the middle portion of the second locking tongue <NUM> to elastically connect the first locking tongue <NUM> and the second locking tongue <NUM>, and the elastic component is configured to apply elastic force to tend to place the first tongue <NUM> and the second tongue <NUM> in a state that the first tongue <NUM> and the second tongue <NUM> can be snapped with the locker <NUM>.

For example, in some examples, as shown in <FIG>, the elastic component includes a torsion spring <NUM>, and the torsion spring <NUM> is configured to apply an elastic force to allow the first end portion <NUM> of the first locking tongue <NUM> and the first end portion <NUM> of the second locking tongue <NUM> approach each other, so that the first end portion <NUM> of the first locking tongue <NUM> and the first end portion <NUM> of the second locking tongue <NUM> are in a clamped state. A second end portion <NUM> of the first locking tongue <NUM> and a second end portion <NUM> of the second locking tongue <NUM> extend to the outside of the second shell <NUM>.

For example, in some examples, by reducing an opening distance between the second end portion <NUM> of the first locking tongue <NUM> and the second end portion <NUM> of the second locking tongue <NUM>, the first end portion <NUM> of the first locking tongue <NUM> and the first end portion <NUM> of the second locking tongue <NUM> are separated from the locker <NUM> in a state of being snapped with the locker <NUM>, so that the first shell <NUM> and the second shell <NUM> are opened.

For example, in some examples, the second opening and closing sub-component <NUM> further includes switches, the switches are arranged in the middle portion of the first locking tongue <NUM> and the middle portion of the second locking tongue <NUM>, and the switches are connected with both the first locking tongue <NUM> and the second locking tongue <NUM>, respectively. In addition, the switches are configured to be operable, so that the first end portion <NUM> of the first locking tongue <NUM> and the first end portion <NUM> of the second locking tongue <NUM> are separated from the locker <NUM> in a state of being snapped with the locker <NUM>.

For example, in some examples, as shown in <FIG>, the second opening and closing sub-component <NUM> further includes a micro switch 1305a and a micro-switch 1305b the micro-switch 1305a is arranged at the second end portion <NUM> of the first locking tongue <NUM>, and the micro-switch 1305b is arranged at the second end poriton1195 of the second locking tongue <NUM>. One of the micro-switch 1305a and the micro-switch 1305b is configured to realize the switch function of the analyzer <NUM>, the other one of the micro-switch 1305a and the micro-switch 1305b is configured to realize the function of the analyzer <NUM> to control the display of the detection results. For example, long time pressing the micro-switch 1305a will turn on the analyzer <NUM>, and start the detection of the detection chip <NUM>. Short time pressing the micro-switch 1305a will turn off the analyzer <NUM>; and pressing the micro-switch 1305b will select the detection results to be displayed.

For example, in some examples, as shown in <FIG>, the second opening and closing sub-component <NUM> further includes a rotating shaft <NUM>, the middle portion of the first locking tongue <NUM> and the middle portion of the second locking tongue <NUM> are connected with each other, and the torsion spring <NUM> is sleeved on the rotating shaft <NUM>.

The limiter track <NUM> is configured to limit the opening and closing angles of the first locking tongue <NUM> and the second locking tongue <NUM> to prevent the opening distance between the first end portion <NUM> of the first locking tongue <NUM> and the first end portion <NUM> of the second locking tongue <NUM> from being too small, and to prevent the second end portion <NUM> of the first locking tongue <NUM> and the second end portion1195 of the second locking tongue <NUM> from being too large, which will cause the opening angle of the second shell <NUM> relative to the first shell <NUM> to be too large. For example, the angle between the second shell <NUM> and the first shell <NUM> is greater than <NUM> degrees, so that the second shell <NUM> rolls over in a direction away from the second side <NUM>, and the analyzer <NUM> is at risk of dumping.

For example, in some examples, as shown in <FIG>, the analyzer <NUM> further includes a displayer device <NUM>, which is arranged at the second shell <NUM>. The displayer device <NUM> 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 <NUM>.

For example, in some examples, as shown in <FIG>, and <FIG>, the analyzer <NUM> further includes a silicone sleeve <NUM>, which is sleeved on the second end portion <NUM> of the first locking tongue <NUM> and the second end portion <NUM> of the second locking tongue <NUM>, to achieve the effects of being beautiful, being dustproof, and preventing light from entering the second shell <NUM>.

For example, in some examples, as shown in <FIG>, light shielding components <NUM> are arranged on the first end portion <NUM> of the first locking tongue <NUM> and the first end portion <NUM> of the second locking tongue <NUM> respectively, to shield the light in the second shell <NUM>.

The controller device <NUM> is also connected with the micro-switch 1305a and the micro-switch 1305b to perform a switching function of the analyzer <NUM> and a function of controlling the display of the detection results on the displayer device <NUM>. For example, long time pressing the micro-switch 1305a will turn on the analyzer <NUM> and start the detection of the detection chip <NUM>, short time pressing the micro-switch 1305a will turn off the analyzer; the display contents of the displayer device <NUM> is controlled by pressing the micro-switch 1305b, and the detection results can be viewed on the displayer device <NUM> according to the selection.

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 <NUM> by installing an application program (APP) on mobile terminals such as mobile phones. For example, in some examples, the analyzer <NUM> further includes a temperature sensor, which is configured to monitor the ambient temperature of the analyzer <NUM>. 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 <NUM> to <NUM>. Therefore, detecting the ambient temperature of the analyzer <NUM> can ensure the accuracy of the detection results.

For example, in some examples, the analyzer <NUM> may also include a humidity sensor, which is configured to detect the environmental humidity of the analyzer <NUM>. 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.

The photoelectric detector unit <NUM> is configured to that in the case where the detection chip <NUM> is placed on the chip placement structure <NUM>, the plurality of detection areas of the detection chip <NUM> can be respectively detected by relative rotation with the detection chip <NUM>, for example, the detection chip <NUM> can be rotated or the photoelectric detector unit can be rotated to detect the plurality of detection areas of the detection chip <NUM> respectively. For example, the photoelectric detector unit <NUM> 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 <NUM> of the analyzer is rotatably arranged in the first shell <NUM> with respect to the chip placement structure <NUM>, 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 <NUM> 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>, the detector unit is arranged on the detection circuit board <NUM>. A central axis <NUM> is arranged at the center of the detection circuit board <NUM>. The analyzer also includes a rotation driver device <NUM>, which is connected with the controller device, in this way, the rotation driver device <NUM> is controlled by the controller device. The rotation driver device <NUM>, for example, may include a servo motor, or a stepping motor. The other end of the central axis <NUM> is connected with the rotation driver device <NUM>, the rotation driver device <NUM> drives the central axis <NUM> to rotate so as to drive the photoelectric detector unit <NUM> of the detector unit to rotate relative to the chip placement structure <NUM>.

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 <NUM>, the detection chip <NUM> is placed on the chip placement structure <NUM>, and the position of the detection chip <NUM> 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 <NUM> is placed on the chip placement structure <NUM>, the position of the detection chip is fixed.

For example, in some examples, the rotation driver device <NUM> receives signals from the controller device and controls a rotation angle of the photoelectric detector unit <NUM>, so that the photoelectric detector unit <NUM> stops rotating in the case where the photoelectric detector unit <NUM> rotates to a position corresponding to a detection area of the detection chip <NUM>, the photoelectric detector unit <NUM> 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 <NUM>, the photoelectric detector unit <NUM> is rotated again to a position corresponding to another detection area of the detection chip <NUM>, 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 <NUM>, 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> is a schematic diagram of a detection chip provided by at least one embodiment of the present disclosure; <FIG> is a schematic diagram of a partial structure of a detection chip provided by at least one embodiment of the present disclosure; <FIG> is an exploded schematic diagram of another detection chip provided by at least one embodiment of the present disclosure.

As shown in <FIG> and <FIG>, the detection chip includes a cover plate <NUM> and a substrate <NUM>. The cover plate <NUM> includes a sample injection opening <NUM> and the cover plate <NUM> is closely attached to the substrate <NUM>. The substrate <NUM> is made of a transparent material to allow the light emitted by the photoelectric detector units <NUM> in the analyzer <NUM> to enter the detection chip <NUM> and the light reflected by the detection chip <NUM> to be transmitted to the photoelectric detector units <NUM>.

For example, in some examples, as shown in <FIG>, a plurality of micro flow channels <NUM>, a plurality of detection areas <NUM>, and a calibration area <NUM> are arranged on the surface of the cover plate <NUM> opposite to the substrate <NUM>. The detection chip includes five detection areas <NUM>. Each of the detection areas <NUM> is connected with one end of the plurality of micro flow channels <NUM>, the other end of plurality of micro flow channels <NUM> extend to the sample injection opening <NUM> of the cover plate <NUM>, so that the liquid to be detected enters the plurality of detection areas <NUM> through the plurality of micro flow channels <NUM>. For example, the center of the calibration area <NUM> and the centers of the plurality of detection areas <NUM> are arranged on the same circumference at equal intervals, the plurality of detection areas <NUM> and the calibration area <NUM> respectively correspond to the photoelectric detector units <NUM> in the detector unit of the analyzer <NUM>. The calibration area <NUM> is configured to detect and systematically calibrate whether there is a detection chip <NUM> on the chip placement structure <NUM> in the analyzer <NUM>.

For example, in the case where the detection chip <NUM> is placed on the chip placement structure <NUM>, the photoelectric detector unit <NUM> corresponding to the calibration area <NUM> can receive the reflected light, so that the photoelectric detector unit <NUM> outputs an electrical signal, thereby determining that a detection chip <NUM> is in the analyzer <NUM> at this time, the controller device can control the detection work of other photoelectric detector units <NUM> according to the electrical signal. Conversely, in the case where the detection chip <NUM> is not placed on the chip placement structure <NUM>, the photoelectric detector unit <NUM> corresponding to the calibration area <NUM> can receive the reflected light with very weak intensity, so that the photoelectric detector unit <NUM> has no electrical signal output, thereby determining that no detection chip <NUM> is in the analyzer <NUM> under this case, and the analyzer <NUM> does not perform detection.

Detection test paper placement areas <NUM> are arranged in the plurality of detection area <NUM>, and detection test papers are placed in the detection test paper placement areas <NUM>, respectively. In addition, detection through holes <NUM> are arranged at the center of the plurality of detection areas <NUM>, respectively. The liquid to be detected enters the plurality of detection area <NUM> and reacts with the detection test paper <NUM> through the detection through holes <NUM>, 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 <NUM>. In addition, the detection through holes <NUM> can also contain excess liquid to be detected.

For example, in some examples, as shown in <FIG>, the plurality of detection areas <NUM> of the detection chip <NUM> is in a diamond shape. For example, the shape of the detection area <NUM> 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 <NUM>.

For example, in some examples, as shown in <FIG>, the detection chip <NUM> further includes a sample injection unit <NUM>. 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 <NUM> is connected with the sample injection opening <NUM> of the cover plate <NUM>, and the liquid to be detected is dropped into the sample injection unit <NUM>, after that, the detection liquid passes through the sample injection opening <NUM> of the cover plate <NUM>, enters the detection area <NUM> of the detection chip through the micro-flow channel <NUM>, and undergoes a color reaction with the detection test paper <NUM>.

For example, in examples of other embodiments, as shown in <FIG>, the sample injection unit <NUM> 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 <NUM>, 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 <NUM> in the detection chip is not necessary, and the detection chip may not be arranged with the calibration area <NUM>. As shown in the example of <FIG>, the detection chip includes six detection areas <NUM>, and no calibration area <NUM> is arranged.

For example, in some examples, as shown in <FIG>, detection light through holes <NUM> are arranged at positions of the substrate <NUM> opposite to the detection through holes <NUM> of the cover plate <NUM>, which allow the light emitted by the photoelectric detector units <NUM> in the analyzer <NUM> to enter the detection chip <NUM> and the light reflected by the detection chip <NUM> to be transmitted to the photoelectric detector units <NUM>.

For example, in some examples, the analyzer shown in <FIG> is configured to detect the substance content of the liquid, and the detection process includes the steps shown in <FIG>.

Step S100: droping 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 <NUM> and the color reaction is completed, the detection chip <NUM> can be subsequently placed in the analyzer <NUM>.

Step S200: opening the first shell and the second shell, and placing the detection chip. The opening distance (the second end portion <NUM> of the first locking tongue <NUM> and the second end portion <NUM> of the second locking tongue <NUM> are moved closer to the middle of the two) between the second end portion <NUM> of the first locking tongue <NUM> and the second end portion <NUM> of the second locking tongue <NUM> is reduced, the first end portion <NUM> of the first locking tongue <NUM> and the first end portion <NUM> of the second locking tongue <NUM> are separated from the locker <NUM> in a state of being snapped with the locker <NUM>, so that the first shell <NUM> and the second shell <NUM> of the analyzer <NUM> are opened, and the detection chip <NUM> is placed in the chip placement structure <NUM>. The embodiments of the present disclosure are not limited to the sequence of step S100 and step S200, for example, after that the detection chip <NUM> is placed in the chip placement structure <NUM>, the liquid to be detected is then dropped into the detection chip <NUM>, which is not specifically limited herein.

The controller device <NUM> receives the detection results of the photoelectric detector units <NUM> and sends the detection results to the displayer device <NUM>.

After the detection of the analyzer <NUM> is completed, the detection results are checked by pressing the micro-switch 1305b 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 S500: retrieving the detection chip and turning off the analyzer. Turning on the first shell <NUM> and the second shell <NUM> of the analyzer <NUM> again, taking the detection chip <NUM> out, then the first shell <NUM> and the second shell <NUM> are closed, and short time pressing the micro-switch 1305a to turn off the analyzer <NUM>.

The analyzer <NUM> can measure the contents of various substances in liquid, such as breast milk, at the same time, the analyzer <NUM> can display the detection results in a short period of time (for example, <NUM>-<NUM> minutes). The above-mentioned analyzer <NUM> 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 <NUM> 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> 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>.

As shown in <FIG>, the analyzer <NUM> includes a detector module <NUM> and a controller module <NUM>. The detector module <NUM> includes a chip placement structure <NUM>. The detector module <NUM> is configured to detect at least one detection area <NUM> of the detection chip <NUM> in the case where the detection chip <NUM> (as shown in <FIG>) includes at least one detection area <NUM> is placed on the chip placement structure <NUM>. The controller module <NUM> is connected in signal with the detector module <NUM>, and is configured to control the detection operation of the detector module <NUM> and receive the detection results of the detector module <NUM>.

For example, in some examples, the chip placement structure <NUM> is a space in which the detection chip <NUM> is placed, and the detection chip <NUM> can be shielded from ambient light in the case where the detection chip <NUM> is detected. For example, the chip placement structure <NUM> may be the structure as shown in <FIG>, in the case where the detector module <NUM> includes the first shell <NUM> and the second shell <NUM>, the chip placement structure <NUM> is located in the first shell <NUM>, for placing the detection chip <NUM>. The first shell <NUM> and the second shell <NUM> can be opened and closed on one side, to facilitate the users to place and retrieve the detection chip <NUM>, and in the case where the analyzer <NUM> is working, the interference of external light on the detection of the detection chip is avoided. The chip placement structure <NUM> is a lower "concave" accommodating space formed in the first shell <NUM> from the opening (for example, the circular opening 1301a of the first shielding plate <NUM> in <FIG>) in the upper surface (for example, formed by the surface of the first shielding plate <NUM> in <FIG>) of the first shell <NUM>. 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 <NUM> only includes the first shell <NUM>, the upper surface of the first shell <NUM> is made into a plane that can shield light, an opening is arranged at the side of the first shell <NUM>, and the opening is connected with the chip placement structure <NUM>. An object stage can be added to the chip placement structure <NUM>, the object stage can be ejected from the opening of the chip placement structure <NUM> to place the detection chip <NUM> on the object stage, and then the object stage is pushed into the chip placement structure <NUM> to detect the detection chip <NUM>. 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 <NUM> is detected.

For example, in some examples, the controller module <NUM> receives the electrical signals sent by the detector module <NUM>, and obtains the detection results according to the electrical signals. For example, the controller device <NUM> 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> is still another schematic diagram of the analyzer provided by at least one embodiment of the present disclosure. As shown in <FIG>, the detector module <NUM> includes at least one photoelectric detector unit <NUM>. The at last one photoelectric detector unit <NUM> may be of various types, for example, including but not limited to at lase one photoelectric detector unit <NUM>. These photoelectric detector units <NUM> are configured to detect the plurality of detection areas <NUM> of the detection chip <NUM> in the case where the detection chip <NUM> is placed on the chip placement structure <NUM>.

For example, in other examples, the detector module <NUM> includes a plurality of photoelectric detector units <NUM>, the plurality of photoelectric detector units <NUM> correspond to the plurality of detection areas <NUM> of the detection chip <NUM> (for example, in the vertical direction, that is, in the axial direction of the first shell <NUM>) respectively.

For example, in some examples, each of the photoelectric detector unit <NUM> includes at least one light-emitter element and at least one photoelectric sensor device. As shown in <FIG>, each of the plurality of photoelectric detector units <NUM> includes two light-emitter elements <NUM> and a photoelectric sensor device <NUM>. For example, the two photoelectric light-emitter elements <NUM> (for example, symmetrical) are located at both sides of a photoelectric sensor device <NUM>. The arrangement of two light-emitter elements <NUM> and one photoelectric sensor device <NUM> can ensure that the light emitted by the light-emitter element <NUM> is evenly incident on corresponding detection area of the detection chip <NUM>, and can also increase the intensity of the incident light provided by the two light-emitter elements <NUM> and the intensity of the reflected light after being reflected by the detection chip <NUM>, thereby improving the stability of analyzer detection. For example, light of a specific intensity (incident light) emitted by the light-emitter element <NUM> is transmitted to the chip placement structure <NUM> to reach the detection chip <NUM> placed on the chip placement structure <NUM>, then the light reflected by the plurality of detection areas <NUM> (the detection sample in the plurality of detection areas <NUM>) of the detection chip <NUM> is received by the photoelectric sensor device <NUM>. The photoelectric sensor device <NUM> will receive light signals (reflected light) and convert the light signals into electrical signals. The controller device <NUM> can obtain the intensity of the light signal received by the photoelectric sensor device <NUM> according to the electrical signals.

For example, in other examples, each of the plurality of photoelectric detector units <NUM> may also include a photoelectric sensor device <NUM> and a light-emitter element <NUM>, and can also realize the detection of the liquid to be detected in the plurality of detection areas <NUM> of the detection chip <NUM>. Alternatively, each of the plurality of photoelectric detector units <NUM> may also include the plurality of photoelectric sensor devices <NUM> and the plurality of light-emitter elements <NUM>, the plurality of photoelectric sensor devices <NUM> can detect different substances in the liquid to be detected.

For example, in some examples, the light-emitter element <NUM> includes a light-emitting diode (Light-emitting Diode, LED), the photoelectric sensor device <NUM> 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 <NUM> are different, so that the plurality of photoelectric detector units <NUM> can detect various substances. For example, a photoelectric detector unit <NUM> can select a light-emitter element that emits light with a wavelength of <NUM>, 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 <NUM> can be obtained, so that the photoelectric detector unit <NUM> obtains the maximum receiving efficiency, thereby improving the accuracy of detection. For example, the photoelectric detector unit <NUM> can also select a light-emitter element that emits light with a wavelength of <NUM>, 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 <NUM> can be obtained, so that the photoelectric detector unit <NUM> obtains the maximum receiving efficiency, thereby improving the accuracy of detection. The photoelectric detector unit <NUM> can also select a light-emitter element that emits light with a wavelength of <NUM>, 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 <NUM> can be obtained, so that the photoelectric detector unit <NUM> obtains the maximum receiving efficiency, thereby improving the accuracy of detection. In this way, the photoelectric sensor device <NUM> of the photoelectric detector unit <NUM> of the analyzer <NUM> 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 <NUM> can transmit a plurality of detection signals to the controller module <NUM>, the controller module <NUM> processes the detection signals to obtain corresponding detection results, and the controller module <NUM> may transmit the detection results to the displayer module <NUM> (as shown in <FIG>, the displayer module <NUM> will be described in detail in the following) for display on the displayer module <NUM>. Therefore, the analyzer <NUM> 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.

Two light-emitting through holes <NUM> are located at both sides of the light-reflecting through hole <NUM>, the light-emitting through holes <NUM> corresponds to the light-emitter elements <NUM> in the photoelectric detector unit <NUM>, and the light-reflecting through hole <NUM> corresponds to the photoelectric sensor device <NUM> in the photoelectric detector unit <NUM>. The light emitted by the light-emitter elements <NUM> passes through the light-emitting through hole <NUM> and then is incident on the chip placement structure <NUM>, and the light reflected from the detection chip <NUM> placed on the chip placement structure <NUM> passes through the light-reflecting through hole <NUM> and then is received by the photoelectric sensor device <NUM>. The arrangement of the light splitter disk <NUM> can avoid the interference of light signals between different photoelectric detector units <NUM> to ensure the reliability of the detection results.

It should be noted that, the light splitter disk <NUM> is an example of the light splitter component <NUM>, and the light splitter component <NUM> can also be selected as other optical path structures, which is not limited in the embodiments of the present disclosure.
