     DETAILED DESCRIPTION 
     Technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the embodiments described are merely a part of the embodiments of the present disclosure, rather than all the embodiments. All other embodiments attained by persons of ordinary skill in the art based on the embodiments of the present disclosure without expending inventive labor shall fall within the protection scope of the present disclosure. 
     The present invention will be described in detail below in conjunction with the drawings and embodiments. 
       FIG. 1  is a schematic structural diagram of a first embodiment of an atomizer identifier applied to an electronic atomization device according to the present disclosure. The atomizer identifier is configured to identify an atomizer connected to a battery pole. The atomizer includes a first contact structure  14  and an atomizer identification circuit  15 . In details, referring to  FIG. 2 a   , the first contact structure  14  includes a first electrode contact H 1 +, a first identification contact ID 1 , and a second electrode contact H 1 −. In order to easily achieve connection of the atomizer to the battery pole in a first connection manner or a second connection manner, the first electrode contact H 1 + and the second electrode contact H 1 − are symmetrically arranged on two sides of the first identification contact ID 1 . Referring to  FIG. 2 a   , the atomizer identification circuit  15  is an identification resistor R 1 . In details, the identification resistor R 1  is connected between the first identification contact ID 1  and the second electrode contact H 1 −. Further, referring to  FIG. 2 a   , the atomizer further includes a heating element R 2 , which is a heating wire. The heating element R 2  is connected between the first electrode contact H 1 + and the second electrode contact H 1 −. An end of the identification resistor R 1  not connected to the first identification contact ID 1  and an end of the heating element R 2  not connected to the first electrode contact H 1 + are connected to the second electrode contact H 1 −.

In order to easily achieve the connection of the atomizer to the battery pole in the first connection manner or in the second connection manner, the positive electrode contact H 2 + and the negative electrode contact H 2 − are respectively symmetrically arranged on two sides of the second identification contact ID 2 . 
     In an embodiment, the atomizer may be inserted into the battery pole to operate. In this way, the atomizer being connected to the battery pole in the first connection manner may be interpreted as the atomizer being positively inserted into the battery pole; and the atomizer being connected to the battery pole in the second connection manner may be interpreted as the atomizer being reversely inserted into the battery pole. In another embodiment, the atomizer may be screwed into the battery pole to operate. In this way, after the atomizer is connected to the battery pole, switching between the connection in the first connection manner and the connection in the second connection manner is achievable by rotating the atomizer at a certain angle. In details, the solution of the present invention is explained with an example where the atomizer is positively inserted into the battery pole in the first connection manner and is reversely inserted into the battery pole in the second connection manner. 
     In other embodiments,  FIG. 2 c    shows another structure of the atomizer. In detail, the structure shown in  FIG. 2 c    is different from the structure of the atomizer shown in  FIG. 2 a   . In the present embodiment, the atomizer identification circuit  15  is an identification chip IC. Specifically, the identification chip IC is connected between the first identification contact ID 1  and the second electrode contact H 1 −.

     In the present application, when either the atomizer shown in  FIG. 2 a    or the atomizer shown in  FIG. 2 c    is connected to the battery pole shown in  FIG. 2 b    in the first connection manner, the first electrode contact H 1 + of the first contact structure  14  in the atomizer is in contact with the positive electrode contact H 2 + of the second contact structure  13  in the battery pole, the first identification contact ID 1  of the first contact structure  14  in the atomizer is in contact with the second identification contact ID 2  of the second contact structure  13  in the battery pole, and the second electrode contact H 1  of the first contact structure  14  in the atomizer is in contact with the negative electrode contact H 2 − of the second contact structure  13  in the battery pole. 
     When either the atomizer shown in  FIG. 2 a    or the atomizer shown in  FIG. 2 c    is connected to the battery pole shown in  FIG. 2 b    in the second connection manner, the first electrode contact H 1 + of the first contact structure  14  in the atomizer is in contact with the negative electrode contact H 2 − of the second contact structure  13  in the battery pole, the first identification contact ID 1  of the first contact structure  14  in the atomizer is in contact with the second identification contact ID 2  of the second contact structure  13  in the battery pole, and the second electrode contact H 1 − of the first contact structure  14  in the atomizer is in contact with the positive electrode contact H 2 + of the second contact structure  13  in the battery pole. 
     In detail, the atomizer identifier shown in the present embodiment further includes an identifier chip  11  and a peripheral circuit  12 . The identifier chip  11  is configured to determine whether an identification voltage is to be provided. The peripheral circuit  12  is connected to the identifier chip  11  and the second contact structure  13 , for being connected to the atomizer identification circuit  15  via the second contact structure  13  and the first contact structure  14  of the atomizer connected to the battery pole. In this way, the atomizer identifier drives the atomizer identification circuit  15  to read and input information of the atomizer identification circuit  15  to the identifier chip  11  based on the identification voltage provided by the identifier chip  11 , thereby obtaining information of the atomizer. In detail, the information of the atomizer identification circuit  15  acquired by the identifier chip  11  is a resistance value of the identification resistor R 1 , which identifies a flavor of the atomizer. 
     In detail, in an embodiment, when the atomizer is connected to the battery pole in the first connection manner, the atomizer identifier connects to the first identification contact ID 1  and the second electrode contact H 1 − of the first contact structure  14  via the second identification contact ID 2  and the negative electrode contact H 2 − of the second contact structure  13 , thereby to further connect to the atomizer identification circuit  15  to form an electric pathway. Alternatively, in an embodiment, when the atomizer is connected to the battery pole in the second connection manner, the atomizer identifier connects to the first identification contact ID 1  and the first electrode contact H 1 + of the first contact structure  14  via the second identification contact ID 2  and the negative electrode contact H 2 − of the second contact structure  13 , thereby to further connect to the atomizer identification circuit  15  to form the electric pathway. When the atomizer is connected to the battery pole in either the first connection manner or the second connection manner, it is possible to drive the atomizer identification circuit  15  based on the identification voltage provided by the identifier chip  11 , so as to read and input the information of the atomizer identification circuit  15  to the identifier chip  11 , thereby obtaining the information of the atomizer. 
     The atomizer identifier applied to the electronic atomization device according to the present disclosure may identify the information of the atomizer identification circuit  15  through the identifier chip  11  when the atomizer is connected to the battery pole in the first connection manner or the second connection manner, thereby identifying the information of the atomizer. In the embodiment shown in the present disclosure, a situation of the identifier chip  11  being burnt may not occur when the atomizer is connected to the battery pole in either the first connection manner or the second connection manner. 
       FIG. 3  is a schematic structural diagram of a second embodiment of an atomizer identifier applied to a battery pole of an electronic atomization device according to the present disclosure. 
     The atomizer identifier shown in the present embodiment is formed by connecting the atomizer shown in  FIG. 2 a    to the battery pole shown in  FIG. 2 b    in the first connection manner. In details, in the present embodiment, the atomizer identification circuit  15  is an identification resistor R 1 . An identifier chip MCU includes an identification voltage output port IO and an information acquisition port ADC. The identification voltage output port IO is configured to output the identification voltage to drive the atomizer identification resistor R 1 . The information acquisition port ADC is connected to the second identification contact ID 2  for acquiring information of the identification resistor R 1 . In the present embodiment, the information of the identification resistor R 1  includes information of the atomizer, and that is identifying different flavors of the atomizer. 
     In the present embodiment, the peripheral circuit  12  specifically includes a primary resistor R 3 . The identification voltage output port IO is connected to the second identification contact ID 2  via the primary resistor R 3 , and the information acquisition port ADC is connected to the second identification contact ID 2 . In another embodiment, the peripheral circuit  12  further includes a current-limiting resistor R 4 . An end of the current-limiting resistor R 4  is connected to the second identification contact ID 2 , and the other end of the current-limiting resistor R 4  is connected to the information acquisition port ADC. 
     In detail, in the present embodiment, an end of the identification resistor R 1  is connected to the second identification contact ID 2 , and the other end of the identification resistor R 1  is connected to the negative electrode contact H 2 − and to a ground voltage GND. It may be understood that, since the atomizer identifier shown in the present embodiment is the atomizer being connected to the battery pole in the first connection manner, and that is, the second identification contact ID 2  contacts the first identification contact ID 1 , the negative electrode contact H 2 − is connected to the second electrode contact H 1 − and to the ground voltage GND. 
     The atomizer identifier shown in the present embodiment is an identifier where the atomizer is connected to the battery pole in the first connection manner. When the atomizer is detected, the negative electrode contact H 2 − is connected to the second electrode contact H 1 − and to the ground voltage GND. The identification voltage output port IO of the identifier chip MCU outputs a high identification voltage. Meanwhile, the information acquisition port ADC of the identifier chip MCU acquires a partial pressure value of the identification resistor R 1  for the high identification voltage and a partial pressure value of the primary resistor R 3  for the high identification voltage, and the information acquisition port ADC of the identifier chip MCU acquires information of the identification resistor R 1  and the primary resistor R 3 , and analyzes the acquired information, thereby obtaining the flavor of the atomizer. 
       FIG. 4  is a schematic structural diagram of a third embodiment of an atomizer identifier applied to an electronic atomization device according to the present disclosure. 
     The atomizer identifier shown in the present embodiment is formed by connecting the atomizer shown in  FIG. 2 a    to the battery pole shown in  FIG. 2 b    in the second connection manner. In details, the embodiment shown in  FIG. 4  is different from the embodiment shown in  FIG. 3 . In details, the atomizer identifier shown in the present embodiment further includes a heating element R 2 . An end of the heating element R 2  is connected to the identification resistor R 1  and the other end of the heating element R 2  is connected to the negative electrode contact H 2 − and to the ground voltage GND. 
     In detail, since the atomizer shown in the present embodiment is connected to the battery pole in the second connection manner, the negative electrode contact H 2 − in the atomizer identifier is in contact with the first electrode contact H 1 +, the second identification contact ID 2  is in contact with the first identification contact ID 1 , and the positive electrode contact H 2 + is in contact with the second electrode contact H 1 −. 
     During operation, the negative electrode contact H 2 − is in contact and electrically connected to the first electrode contact H 1 +; and the identification resistor R 1  and the heating element R 2  are connected in series. In this situation, the identification resistor R 1  and the heating element R 2  work cooperatively with the primary resistor R 3  to perform voltage partitioning on the identification voltage provided by the identification voltage output port IO of the identifier chip MCU. Since a resistance value of the identification resistor R 1  is relatively great, whereas a resistance value of the heating element R 2  is relatively small, the resistance value of the heating element R 2  may be ignored in this case. The information acquisition port ADC of the identifier chip MCU may obtain the information of the atomizer by acquiring partial pressure values of the identification resistor R 1  and the primary resistor R 3 , thereby obtaining the flavor of the atomizer. 
     In an embodiment, the resistance value of the identification resistor R 1  is on a kiloohm level, for example, approximately 1 kiloohm, and the resistance value of the heating element R 2  is on an ohm level, for example, approximately 1 ohm. It may be understood that, since the resistance value of the heating element R 2  is significantly smaller than the resistance value of the identification resistor R 1 , the resistance value of the heating element R 2  in  FIG. 4  may be ignored. In the atomizer identifier shown in  FIGS. 3 and 4 , at the entry into a suction stage after identifying the information of the atomizer, that is, when an airflow signal is detected at a mouthpiece, the electronic atomization device performs an atomizing operation. In this situation, the identification voltage output port IO of the identifier chip MCU outputs a low voltage, and another control end of the identifier chip MCU outputs a corresponding PWM signal based on the identified information of the atomizer, such that the positive electrode contact H 2 + is electrically connected to a power supply (not shown) via the PWM signal to control the heating element R 2  through the PWM signal to generate heat for normal inhalation. During inhalation, the identification voltage output port  10  of the identifier chip MCU outputs a low voltage, the identifier chip MCU may not be burnt. Further, except that the identification voltage output port IO of the identifier chip MCU outputs a high voltage while identifying the atomizer information, the identification voltage output port  10  of the identifier chip MCU outputs a low voltage in each of the remaining stages. In this way, current consumption is further reduced to achieve an energy-saving effect. 
       FIG. 5  is a schematic structural diagram of a fourth embodiment of an atomizer identifier applied to an electronic atomization device according to the present disclosure. 
     The present embodiment is a schematic structural diagram showing that the atomizer shown in  FIG. 2 a    is connected to the atomizer identifier in the battery pole shown in  FIG. 2 b    in the second connection manner. In detail, in the present embodiment, the identifier chip MCU includes an identification voltage control port  10  and an information acquisition port ADC. The identification voltage control port  10  is configured to output an identification voltage control signal to determine whether the identification voltage is to be output, and the information acquisition port ADC is connected to the second identification contact ID 2  to acquire information of the atomizer identification circuit. As identical to the embodiments described in  FIGS. 3 and 4 , the atomizer identification circuit  15  in the present embodiment is an identification resistor R 1 . 
     In detail, the peripheral circuit  12  of the atomizer identifier according to the present embodiment includes an identification voltage source VDD, a primary resistor R 3 , a control switch K 1 , and a current-limiting resistor R 4 . The identification voltage source VDD, the control switch K 1  and the primary resistor R 3  are connected in series to the second identification contact ID 2 . In details, an end of the control switch K 1  is connected to the identification voltage source VDD and the other end of the control switch K 1  is connected to an end of the primary resistor R 3 ; and an end of the primary resistor R 3  is connected to the second identification contact ID 2 . The control switch K 1  receives an identification voltage control signal from the identification voltage source VDD to determine whether to open a pathway between the identification voltage source VDD and the second identification contact ID 2  based on the identification voltage control signal. The information acquisition port ADC is connected to the second identification contact ID 2  via the current-limiting resistor R 4 . In details, an end of the current-limiting resistor R 4  is connected to the information acquisition port ADC, and the other end of the current-limiting resistor R 4  is connected to the second identification contact ID 2 . 
     As identical to the embodiments shown in  FIGS. 3 and 4 , an end of the identification resistor R 1  is connected to the second identification contact ID 2 , and the other end thereof is connected to the ground voltage GND. 
     In the present embodiment, the control switch K 1  is a triode, and a control end of the control switch K 1  is connected to the identification voltage control port IO of the identifier chip MCU. At a stage of identifying the atomizer, the identification voltage control port IO of the identifier chip MCU controls the control switch K 1  to be turned on to provide the identification voltage, and then derives the information of the atomizer based on voltage partitioning of the identification resistor R 1  and the primary resistor R 3 . In this way, the flavor of the atomizer is identified. At the inhalation stage, the identification voltage control port IO of the identifier chip MCU controls the control switch K 1  to be turned off. In this situation, the identifier chip MCU is not electrically connected to the atomizer, and therefore, the identifier chip MCU may not be burnt. 
       FIG. 6  is a schematic structural diagram of a fifth embodiment of an atomizer identifier applied to an electronic atomization device according to the present disclosure. 
     The atomizer identifier according to the present embodiment is formed by means of the atomizer shown in  FIG. 2 c    being connected to the battery pole shown in  FIG. 2 b    in the first connection manner. In the present embodiment, the atomizer identification circuit is an identification chip IC. 
     The identifier chip MCU includes an identification voltage output and information acquisition port IO. In the present embodiment, the identification voltage output and information acquisition port IO is connected to the second identification contact ID 2 , for outputting the identification voltage to the second identification contact ID 2  and acquiring information of the atomizer in the identification chip IC from the second identification contact ID 2 , thereby obtaining the flavor of the atomizer. 
     In the present embodiment, the peripheral circuit  12  of the atomizer identifier includes a current-limiting resistor R 4 , and the identification voltage output and information acquisition port IO is connected to the second identification contact ID 2  via the current-limiting resistor R 4 . In details, an end of the current-limiting resistor R 4  is connected to the identification voltage output and information acquisition port IO and the other end of the current-limiting resistor R 4  is connected to the second identification contact ID 2 . An end of the identification chip IC is connected to the second identification contact ID 2  and the other end of the identification chip IC is connected to the ground voltage GND. 
     It may be understood that, in the present embodiment, the atomizer is connected to the atomizer identifier in the battery pole in the first connection manner. Therefore, the second identification contact ID 2  is in contact with the first identification contact ID 1 ; the negative electrode contact H 2 − is in contact with the second electrode contact H 1 −; and the positive electrode contact H 2 + is in contact with the first electrode contact H 1 +. 
     The atomizer identifier according to the present embodiment further includes a diode D, and a unidirectional conduction of the identification voltage from the second identification contact ID 2  to the ground voltage GND may be achieved by virtue of the diode D. In details, an anode of the diode D is connected to the identification chip IC, and a cathode of the diode D is connected to the negative electrode contact H 2 −. 
     In the present embodiment, the negative electrode contact H 2 − is conducted to the second electrode contact H 1 −. The identification voltage output and information acquisition port IO of the identifier chip MCU supply power to the identification chip IC through the second identification contact ID 2 , and the identification chip IC feeds back the information of the atomizer from the identification voltage output and information acquisition port IO to the identifier chip MCU, thereby obtaining the flavor of the atomizer. 
       FIG. 7  is a schematic structural diagram of a sixth embodiment of an atomizer identifier applied to an electronic atomization device according to the present disclosure. 
     The atomizer identifier according to the present embodiment is formed by means of the atomizer shown in  FIG. 2 c    being connected to the battery pole shown in  FIG. 2 b    in the second connection manner. In the present embodiment, the atomizer identification circuit is an identification chip IC. 
     The sixth embodiment shown in  FIG. 7  is different from the fifth embodiment shown in  FIG. 6 . The atomizer identifier according to the present embodiment further includes a heating element R 2 . An end of the heating element R 2  is connected to an end of the identification chip IC, and the other end of the heating element R 2  is connected to a ground voltage GND. Further, the present embodiment further includes a diode D. An anode of the diode D is connected to the identification chip IC, and a cathode of the diode D is connected to the heating element R 2 . 
     It may be understood that the atomizer identifier shown in the present embodiment is formed by means of the atomizer being connected to the battery pole in the second connection manner. Therefore, the negative electrode contact H 2 − is connected to the first electrode contact H 1 +; the second identification contact ID 2  is connected to the first identification contact ID 1 ; and the positive electrode contact H 2 + is connected to the second electrode contact H 1 −. 
     In the present embodiment, the negative electrode contact H 2 − is connected to the first electrode contact H 1 +; and the identification chip IC is conducted to the ground voltage GND via the diode D and the heating element R 2 . The resistance value of the heating element R 2  is relatively small, and therefore, resistance value may be ignored. After the identification voltage output and information acquisition port  10  of the identifier chip supply power to the identification chip IC, it is possible to read identifiable information of the atomizer in the identification chip IC through the identification voltage output and information acquisition port IO, thereby obtaining the flavor of the atomizer. 
     When the atomizer identifiers shown in  FIGS. 6 and 7  enter the inhalation stage after the information of the atomizer being identified, that is, when the airflow signal is detected, the electronic atomization device performs the atomizing operation. At this time, the identification voltage output and information acquisition port IO of the identifier chip MCU outputs a low voltage, and the identifier chip MCU outputs a corresponding PWM signal based on the atomizer information identified by the identification chip IC, such that the positive electrode contact H 2 + is electrically connected to a power supply (not shown) via the PWM signal to control the heating element R 2  through the PWM signal to generate heat for normal inhalation. During the inhalation process, the identification voltage output and information acquisition port  10  of the identifier chip MCU outputs a low voltage, and the identifier chip MCU may not be burnt. Further, except that the identification voltage output and information acquisition port IO of the identifier chip MCU outputs a high voltage during the process of identifying the atomizer information, the identification voltage output port IO of the identifier chip MCU outputs a low voltage in each of the remaining stages. In this way, current consumption may be reduced to achieve the energy-saving effect. In addition, since the circuit is provided with the diode D, the identification voltage may be transmitted unidirectionally via the diode D, i.e., unidirectional transmission of the identification voltage from the second identification contact ID 2  to the ground voltage GND, without damaging the identification chip IC. Further, when the atomizer is connected to the battery pole in the second connection manner, and when the positive electrode contact H 2 + is electrically connected to the power supply via the PWM signal, the PWM signal may not be transmitted to the identification chip IC, given that the circuit is provided with the diode D, and therefore, the identification chip IC may not be affected. 
     The atomizer identifier applied to the battery pole of the electronic atomization device according to the present disclosure supplies power and reads the information of the atomizer via the identifier chip MCU and performs control via software. In this way, the information of the atomizer may be identified securely, when the atomizer and the battery pole are connected in the first connection manner or the second connection manner, and the atomizer identifier may be protected from damage at the inhalation stage. 
       FIG. 8  is a schematic structural diagram of a battery pole of an electronic atomization device according to the present disclosure. In details, a battery pole  91  includes an atomizer identifier  92 , which is an atomizer identifier  92  described in any of the embodiments in  FIGS. 1 to 7 . The atomizer identifier  92  is configured to identify the information of the atomizer connected to the battery pole, thereby obtaining the flavor of the atomizer. 
     The battery pole according to the present disclosure may securely identify the information of the atomizer when the atomizer is connected in either the first connection manner or the second connection manner, and may not harm the atomizer identifier  92  during the inhalation process. 
     The battery pole according to the present disclosure only describes a part of the structure, and the other structures are the same as those in the prior art, which will not be detailed herein.
