     The technical solutions in embodiments of this application are clearly and completely described below with reference to the accompanying drawings in the embodiments of this application. Apparently, the described embodiments are merely some rather than all of the embodiments of this application. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of this application without creative efforts shall fall within the protection scope of this application. 
     The present invention is further described in detail below with reference to the accompanying drawings and the embodiments. 
       FIG.  1    is a schematic structural diagram of an embodiment of a battery rod according to the present invention. The battery rod  11  is configured to supply power to a vaporizer inserted therein. Specifically, the battery rod  11  includes a power supply identifying circuit. When the vaporizer is inserted into the battery rod  11 , the power supply identifying circuit receives identification information fed back by the vaporizer, and uses, according to the identification information fed back, a corresponding power to drive the vaporizer. Further, the battery rod  11  includes a power supply voltage connection end n 1  and a ground voltage connection end n 2 . 
     Specifically, the power supply identifying circuit includes: a first control chip  111 , a first switch M 1 , a second switch M 2 , and a first resistor R 1 . The first control chip  111  includes a first drive end P 1 , a second drive end P 2 , and a feedback end ADC. The first switch M 1  includes a control end, a first channel end, and a second channel end. The control end of the first switch M 1  is connected to the first drive end P 1  of the first control chip  111  to receive a first drive signal, the first channel end of the first switch M 1  is connected to a power supply voltage VCC, and the second channel end of the first switch M 1  is connected to the power supply voltage connection end n 1  of the battery rod  11 . The second switch M 2  includes a control end, a first channel end, and a second channel end. The control end of the second switch M 2  is connected to the second drive end P 2  to receive a second drive signal, the first channel end of the second switch M 2  is connected to the power supply voltage VCC, and the second channel end of the second switch M 2  is connected to the power supply voltage connection end n 1  of the battery rod  11  through the first resistor R 1 . Specifically, the first resistor R 1  includes a first channel end and a second channel end, the first channel end of the first resistor R 1  is connected to the power supply voltage connection end n 1  of the battery rod  11 , and the second channel end of the first resistor R 1  is connected to the second channel end of the second switch M 2 . The feedback end ADC of the first control chip  111  is connected to the power supply voltage connection end n 1  of the battery rod  11 , and the ground voltage connection end n 2  of the battery rod  11  is connected to a ground voltage GND. 
     In an embodiment, if the vaporizer inserted into the battery rod  11  does not include an identification circuit, the second drive end P 2  of the first control chip  111  outputs the second drive signal, and the second drive signal is used to turn on the second switch M 2 . The first resistor R 1  and a heating element in the vaporizer are connected in series between the power supply voltage VCC and the ground voltage GND. The feedback end ADC receives a feedback voltage on the power supply voltage connection end n 1  of the battery rod  11  between the first resistor R 1  and the heating element to determine performance parameters of a heating wire. The first control chip  111  adjusts the first drive signal outputted by the first drive end P 1  according to the feedback voltage, so that the battery rod  11  uses the corresponding power to drive the heating element in the vaporizer, and further heats a vaporization substrate in the vaporizer. 
     In the embodiments of the present invention, to realize mutual identification of the battery rod  11  and the vaporizer, the vaporizer inserted into the battery rod  11  includes an identification circuit. Specifically, when the vaporizer inserted into the battery rod  11  includes the identification circuit, the first control chip  111  controls the first switch M 1  by using the first drive signal to supply power to the vaporizer, and controls the second switch M 2  by using the second drive signal to communicate with the identification circuit of the vaporizer, to obtain the identification information of the vaporizer, and adjust the first drive signal according to the identification information fed back to use the corresponding power to drive the vaporizer. That is, when the vaporizer inserted into the battery rod  11  includes the identification circuit, the first switch M 1  and the second switch M 2  further have the function of obtaining the identification information of the vaporizer in addition to the function of driving the heating element to heat. 
     Specifically, with reference to  FIG.  2    and  FIG.  3   , when the vaporizer is inserted into the battery rod  11 , the battery rod  11  supplies power to the vaporizer to perform a power-on period L 1 , and executes a data sending period L 2 , a response waiting period L 3 , and a feedback data receiving period L 4 . 
     Specifically, when the vaporizer with the identification circuit is inserted into the battery rod  11 , the battery rod  11  supplies power to the vaporizer, that is, the power-on period L 1  is performed. During the power-on period L 1 , the first drive end P 1  of the first control chip  111  outputs the first drive signal. Specifically, the first drive signal drives the first switch M 1  with a pulse signal formed by a first logic level of a first duration and a second logic level of a second duration, so that the vaporizer is powered on to work. Specifically, in a specific embodiment, the first logic level is a high-level signal, the second logic level is a low-level signal, the first logic level of the first duration is a high-level signal of 50 us, and the second logic level of the second duration is a low-level signal of 500 us. Specifically, the first drive end P 1  of the first control chip  111  of the battery rod  11  applies a pulse signal formed by the high-level signal of 50 us and the low-level signal of 500 us to the first switch M 1 , to drive the first switch M 1  to be turned on. After the first switch M 1  is turned on, the power supply voltage VCC charges the vaporizer through the first switch M 1 , thereby providing electric energy for the vaporizer. In an embodiment, it generally takes 6 ms to power on the vaporizer. Therefore, before the vaporizer is woken up, the first drive end P 1  outputs a plurality of pulse signals 
     During the data sending period L 2 , the first drive signal drives the first switch M 1  by using a pulse signal formed by a first logic level of an eighth duration, and a second logic level of a ninth duration or a second logic level of a tenth duration, to generate a sending voltage of the ninth duration or a sending voltage of the tenth duration at the power supply voltage connection end n 1  of the battery rod  11  as a corresponding sending digital signal, to form sending data to be sent to the vaporizer. Specifically, the first logic level of the eighth duration is a high-level signal of 200 us, the second logic level of the ninth duration is a low-level signal of 500 us, and the second logic level of the tenth duration is a low-level signal of 250 us. In a specific embodiment, the first drive signal may drive the first switch M 1  by using a pulse signal formed by the high-level signal of 200 us and the low-level signal of 500 us, to generate a sending voltage of the low-level signal of 500 us at the power supply voltage connection end n 1  of the battery rod  11 , and send the sending voltage to the vaporizer. Alternatively, the first drive signal may alternatively drive the first switch M 1  by using a pulse signal formed by the high-level signal of 200 us and the low-level signal of 250 us, to generate a sending voltage of the low-level signal of 250 us at the power supply voltage connection end n 1  of the battery rod  11 , and send the sending voltage to the vaporizer. Specifically, when the sending voltage is a low-level signal of 500 us, data “1” can be sent; and when the sending voltage is a low-level signal of 250 us, data “0” can be sent. 
     During the response waiting period L 3 , the first drive signal drives the first switch M 1  by using a pulse signal formed by a first logic level of an eleventh duration and a second logic level of a twelfth duration; and when the first drive signal is at the second logic level, the second drive signal drives the second switch M 2  by using a pulse signal formed by a first logic level of a thirteenth duration and a second logic level of a fourteenth duration. When the identification circuit of the vaporizer sends a response to perform a discharge operation on the power supply voltage connection end n 1  of the battery rod  11 , a waiting voltage of the thirteenth duration of the power supply voltage connection end n 1  of the battery rod  11  is switched to a response voltage of a fifteenth duration, which is then fed back to the feedback end of the first control chip  111 , thereby informing the first control chip  111  to wait to receive the identification information fed back. Specifically, the first logic level of the eleventh duration may be a high-level signal of 200 us, and the second logic level of the twelfth duration may be a low-level signal of 700 us; and the first drive signal drives the first switch M 1  by using a pulse signal formed by the high-level signal of 200 us and the low-level signal of 700 us. The first logic level of the thirteenth duration is a high-level signal of 300 us, and the second logic of the fourteenth duration is a low-level signal of 400 us. Specifically, when the first drive signal is at the low-level signal of 700 us, the second drive signal drives the second switch M 2  by using a pulse signal formed by the high-level signal of 300 us and the low-level signal of 400 us. Specifically, when the vaporizer receives the sending voltage, the identification circuit of the vaporizer sends a response to perform a discharge operation on the power supply voltage connection end n 1  of the battery rod  11 . In this case, the second high-level signal of 300 us of the power supply voltage connection end n 1  of the battery rod  11  is switched to a second high-level signal of 150 us to form a response voltage, which is then fed back to the feedback end ADC of the first control chip  111 , thereby informing the first control chip  111  to wait to receive the identification information fed back. 
     During the feedback data receiving period L 4 , the first drive signal drives the first switch M 1  by using a pulse signal formed by a first logic level of a third duration and a second logic level of a fourth duration, to supply power to the vaporizer. When the first drive signal is at the second logic level, the second drive signal drives the second switch M 2  by using a pulse signal formed by a first logic level of a fifth duration and a second logic level of a sixth duration. When the second drive signal is at the first logic level, the identification circuit of the vaporizer determines to perform the discharge operation on the power supply voltage connection end n 1  of the battery rod  11  according to the identification information, to generate a feedback voltage of the fifth duration or a feedback voltage of a seventh duration at the power supply voltage connection end n 1  of the battery rod  11  as a corresponding feedback digital signal, to form identification information to be fed back to the feedback end ADC of the first control chip  111 . Specifically, the first logic level of the third duration is a high-level signal of 200 us, and the second logic level of the fourth duration is a low-level signal of 700 us. The first drive signal drives the first switch M 1  by using the high-level signal of 200 us and the low-level signal of 700 us to supply power to the vaporizer. The first logic level of the fifth duration is a high-level signal of 300 us, and the second logic level of the sixth duration is a low-level signal of 400 us. In a specific embodiment, when the first drive signal is at the low-level signal of 700 us, the second drive signal drives the second switch M 2  by using the pulse signal formed by the high-level signal of 300 us and the low-level signal of 400 us. In addition, when the second drive signal is at the high-level signal of 300 us, the identification circuit of the vaporizer performs the discharge operation on the power supply voltage connection end n 1  of the battery rod  11 , to generate a high-level signal of 300 us or a high-level signal of 150 us at the power supply voltage connection end n 1  of the battery rod  11  as a corresponding feedback digital signal, to form identification information to be fed back to the feedback end ADC of the first control chip  111 . The high-level signal of 150 us is the feedback voltage of the seventh duration. Specifically, in an embodiment, if the feedback voltage received by the feedback end ADC of the first control chip  111  is the high-level signal of 300 us, it indicates that the data “1” returned by the vaporizer is received. If the feedback voltage received by the feedback end ADC of the first control chip  111  is the high-level signal of 150 us, it indicates that the data “0” returned by the vaporizer is received. It may be understood that, as shown in  FIG.  3   , the feedback voltage of the high-level signal received by the feedback end ADC of the first control chip  111  is a resistance value of the heating element H and a voltage division value of the first resistor R 1 , and has a voltage value lower than the high-level signals outputted from the first drive signal and the second drive signal. 
     In a specific embodiment, the first switch M 1  and the second switch M 2  may be NMOS transistors and PMOS transistors, or may be PNP transistors and NPN transistors. The first control chip  111  may be a general-purpose programmable control chip, or a customized non-programmable control chip, which is not specifically limited. 
     The battery rod provided in the present invention includes the power supply identifying circuit. When the vaporizer is inserted into the battery rod, the power supply identifying circuit receives the identification information fed back by the vaporizer, and uses, according to the identification information fed back, the corresponding power to drive the vaporizer, so that the problem of poor user experience caused by mixing a battery rod and a vaporizer of different models can be avoided, and the vaporizer can be driven with the power matching the vaporizer. Further, a vaporization substrate in the vaporizer can still obtain the expected effect after vaporization, which improves the user experience. 
       FIG.  4    is a schematic structural diagram of a first embodiment of a vaporizer according to the present invention. Specifically, a vaporizer  12  is configured to be inserted into a battery rod  11  to use the battery rod  11  to supply power to the vaporizer  12 . The vaporizer  12  includes a heating element H, where one end of the heating element H is connected to a power supply voltage connection end m 1  of the vaporizer  12 , and the other end is connected to a ground voltage connection end m 2  of the vaporizer  12 . When the vaporizer  12  is inserted into the battery rod  11 , the power supply voltage connection end m 1  and the ground voltage connection end m 2  of the vaporizer  12  are respectively connected to a power supply voltage connection end n 1  and a ground voltage connection end n 2  of the battery rod  11 . Further, a power supply identifying circuit of the battery rod  11  is used to identify the vaporizer  12 , and a corresponding power is used to drive the vaporizer  12 . 
     The vaporizer  12  further includes an identification circuit. The identification circuit is connected in parallel with the heating element H and connected to the power supply voltage connection end m 1  and the ground voltage connection end m 2  of the vaporizer  12 , and is configured to communicate with the power supply identifying circuit of the battery rod  11 , to feed back identification information to the battery rod  11 , for the battery rod  11  to use, according to the identification information fed back, a corresponding power to drive the heating element H of the vaporizer  12 , thereby vaporizing a vaporization substrate in the vaporizer  12 . 
     In a specific embodiment, the vaporizer  12  further includes a liquid storage chamber, and the heating element H may be placed in the liquid storage chamber. The liquid storage chamber stores a vaporization substrate, for example, e-liquid. When the battery rod  11  uses the corresponding power to drive the heating element H, the heating element H generates heat and vaporizes the e-liquid stored in the liquid storage chamber. 
     Specifically, the identification circuit includes: a second control chip  121 , a switch module Q 3 , and a storage capacitor C 1 . The second control chip  121  includes a power supply end VCC, a signal acquisition end P 4 , and a drive end P 3 . The storage capacitor C 1  includes the first end and the second end. The first end of the storage capacitor C 1  is connected to the power supply voltage connection end m 1  of the vaporizer  12 , the second end of the storage capacitor C 1  is connected to the ground voltage connection end m 2  of the vaporizer  12 , and the first end of the storage capacitor C 1  is connected to the power supply end of the second control chip  121 . The switch module Q 3  includes a first channel end, a second channel end, and a control end, where the control end of the switch module Q 3  is connected to the drive end P 3  of the second control chip  121 , the first channel end of the switch module Q 3  is connected to the power supply voltage connection end m 1  of the vaporizer  12 , and the second channel end of the switch module Q 3  is connected to the ground voltage connection end m 2  of the vaporizer  12 . The signal acquisition end P 4  of the second control chip  121  is connected to the power supply voltage connection end m 1  of the vaporizer  12 . 
     In an embodiment, when the vaporizer  12  is inserted into the battery rod  11 , referring to  FIG.  3    together,  FIG.  3    is a schematic timing diagram of a waveform of a power supply voltage connection end n 1  when the vaporizer is inserted into the battery rod. Further,  FIG.  3    is also a schematic timing diagram of a waveform at a point A when the vaporizer shown in  FIG.  4    is inserted into the battery rod shown in  FIG.  1   . Specifically, when the battery rod  11  operates in the power-on period L 1 , the first drive end P 1  of the first control chip  111  outputs a first drive signal. Specifically, the first drive signal drives the first switch M 1  by using a pulse signal formed by a first logic level of 50 us and a second logic level of 500 us, so that the first switch M 1  in the battery rod  11  is turned on, and a power supply voltage VCC charges the storage capacitor C 1  through the first switch M 1 , thereby providing electric energy to the second control chip  121  in the vaporizer  12 . Further, the identification circuit further includes a first diode D 1 , and the first diode D 1  includes the first end and the second end. The first end of the first diode D 1  is connected to the power supply voltage connection end m 1  of the vaporizer  12 , and the second end of the first diode D 1  is connected to the power supply end of the second control chip  121 . When the vaporizer  12  is charged, the first diode D 1  is configured to prevent a reverse voltage from damaging the second control chip  121  of the vaporizer  12 , and the first diode D 1  can further prevent other circuits from consuming energy. Specifically, when the storage capacitor C 1  is charged to a high level, and the first drive signal has a low-level signal, if the first diode D 1  does not exist, the storage capacitor C 1  is discharged through the heating wire H, thereby consuming energy. 
     When the battery rod  11  operates in the data sending period L 2 , the signal acquisition end P 4  of the second control chip  121  acquires a sending voltage of a ninth duration or a sending voltage of a tenth duration at the power supply voltage connection end m 1  of the vaporizer  12  as a correspondingly sending digital signal, thereby acquiring and generating corresponding sending data. Specifically, when the battery rod  11  operates in the data sending period L 2 , a low-level signal of 500 us or a sending voltage of a low-level signal of 250 us is generated at the power supply voltage connection end n 1  of the battery rod  11 . Specifically, if the power supply voltage connection end n 1  of the battery rod  11  generates the low-level signal of 500 us, it indicates that the battery rod  11  sends data “1”; and if the power supply voltage connection end n 1  of the battery rod  11  generates the low-level signal of 250 us, it indicates that the battery rod  11  sends data “0”. 
     In this case, if the signal acquisition end P 4  of the second control chip  121  acquires the low-level signal with the sending voltage of 500 us at the power supply voltage connection end m 1  of the vaporizer  12 , it indicates that the vaporizer  12  receives the data “1”; and if the signal acquisition end P 4  of the second control chip  121  acquires the low-level signal with the sending voltage of 250 us at the power supply voltage connection end m 1  of the vaporizer  12 , it indicates that the vaporizer  12  receives the data “0”. 
     Specifically, in an embodiment, the second control chip  121  further includes a timer  122 , and the timer  122  cooperates with the signal acquisition end P 4  to identify the sending voltage of the ninth duration or the sending voltage of the tenth duration at the power supply voltage connection end m 1  of the vaporizer  12 . Specifically, when the signal acquisition end of the second control chip  121  of the vaporizer  12  receives a low-level signal, the timer  122  is started to work. If the timer  122  displays a time of 500 us, it indicates that the vaporizer  12  receives the data “1”; and if the timer  122  displays a time of 250 us, it indicates that the vaporizer  12  receives the data “0”. Alternatively, in another embodiment, the second control chip further includes an analog-to-digital conversion module  123 . For details, reference may be made to  FIG.  5   .  FIG.  5    is a schematic structural diagram of a second embodiment of a vaporizer according to the present invention. The signal acquisition end P 4  is an analog-to-digital conversion end ADC, configured to identify the sending voltage of the ninth duration or the sending voltage of the tenth duration at the power supply voltage connection end m 1  of the vaporizer  12 . Specifically, in the data sending period L 2 , the battery rod  11  turns on the first switch M 1  to charge the storage capacitor C 1  every cycle, turns on the first switch M 2 , and then sends, through the second switch M 2 , sending voltages with different pulse widths of 300 us and 150 us to the analog-to-digital conversion end of the second control chip  121  of the vaporizer  12  for acquisition and identification. When the analog-to-digital conversion end of the second control chip  121  of the vaporizer  12  acquires the sending voltage for a duration of 300 us, it indicates that the vaporizer  12  receives the data “1”; and when the analog-to-digital conversion end of the second control chip  121  of the vaporizer  12  acquires the sending voltage for a duration of 150 us, it indicates that the vaporizer  12  receives the data “0”. In a specific embodiment, considering the costs, in practical applications, the vaporizer of the first embodiment shown in  FIG.  4    is preferably used, which has lower costs compared with the vaporizer of the second embodiment shown in  FIG.  5   . 
     When the battery rod  11  operates in the response waiting period L 3 , the second control chip  121  controls the switch module Q 3  to perform the discharge operation on the power supply voltage connection end m 1  of the vaporizer  12 , so that the waiting voltage of the thirteenth duration at the power supply voltage connection end m 1  of the vaporizer  12  is switched to the response voltage of the fifteenth duration, and a response signal is generated at the power supply voltage connection end m 1  of the vaporizer  12  to notify the first control chip  111  to wait to receive the identification information fed back. Specifically, when the battery rod  11  operates in the response waiting period L 3 , a second drive signal outputted by the second drive end P 2  of the first control chip  111  of the battery rod  11  is a high-level signal of 300 us. If the vaporizer  12  is still in a process of processing data, the drive end P 3  of the second control chip  121  of the vaporizer  12  does not output any signal, that is, in a low-level state. In this case, the level of the power supply voltage connection end m 1  of the vaporizer  12  continues to be a high-level signal of 300 us. If the vaporizer  12  has received sending data and returns a corresponding voltage, the drive end P 3  of the second control chip  121  of the vaporizer  12  outputs a high-level signal of 150 us, so that level of the power supply voltage connection end m 1  of the vaporizer  12  is switched from the high-level signal of 300 us to the high-level signal of 150 us. In this case, the feedback end ADC of the first control chip  111  of the battery rod  11  acquires a response voltage of the power supply voltage connection end m 1  of the vaporizer  12 . If a duration of the response voltage is not 300 us but 150 us, it indicates that the vaporizer has responded. When the battery rod  11  operates in the feedback data receiving period L 4 , the second control chip  121  controls the switch module Q 3  to determine the discharge operation on the power supply voltage connection end m 1  of the vaporizer  12 , so that the power supply voltage connection end m 1  of the vaporizer  12  generates the feedback voltage of the fifth duration or the feedback voltage of the seventh duration as a corresponding feedback digital signal to form the identification information fed back. Specifically, when the battery rod  11  operates in the feedback data receiving period L 4 , the second drive end P 2  of the first control chip  111  of the battery rod  11  applies the high-level signal of 300 us to the second switch M 2 . If the drive end P 3  of the second control chip  121  of the vaporizer  12  outputs a low-level signal, that is, the switch module Q 3  is turned off or outputs the data “1”, the voltage of the power supply voltage connection end m 1  of the vaporizer  12  in this case continues to be the high-level signal of 300 us; and if the drive end P 3  of the second control chip  121  of the vaporizer  12  outputs a high-level signal, that is, the switch module Q 3  is turned on or outputs the data “0”, the voltage of the power supply voltage connection end m 1  of the vaporizer  12  continues to be the high-level signal of 150 us. In this case, if the feedback end ADC of the first control chip  111  of the battery rod  11  acquires that the voltage of the power supply voltage connection end m 1  of the vaporizer  12  continues to be the high-level signal of 300 us, it indicates that the data “1” returned by the vaporizer  12  is received; and if the feedback end ADC of the first control chip  111  of the battery rod  11  acquires that the voltage of the power supply voltage connection end m 1  of the vaporizer  12  continues to be the high-level signal of 150 us, the data “0” returned by the vaporizer  12  is received. 
     It may be understood that the waveforms shown in  FIG.  2    and  FIG.  3    are only examples, and the present invention is not limited thereto. 
     The vaporizer provided in the present invention includes an identification circuit. The identification circuit is connected in parallel with the heating element and connected to the power supply voltage connection end m 1  and the ground voltage connection end m 2  of the vaporizer, and is configured to communicate with the power supply identifying circuit of the battery rod, to feed back identification information to the battery rod. Therefore, the battery rod uses, according to the identification information fed back, the corresponding power to drive the heating element of the vaporizer, so that the problem of poor user experience caused by mixing a battery rod and a vaporizer of different models can be avoided, and the vaporizer can be driven with the power matching the vaporizer. Further, a vaporization substrate in the vaporizer can still obtain the expected effect after vaporization, which improves the user experience. 
       FIG.  6    is a schematic structural diagram of a third embodiment of a vaporizer according to the present invention. In this embodiment, the vaporizer  12  further includes a level exchange module  125 . The level exchange module  125  is connected between the identification circuit and a first input end and a second input end of the vaporizer  12 , for the vaporizer to be inserted into the battery rod  11  rightly or reversely. In addition, one of the first input end or the second input end of the vaporizer  12  is used as the power supply voltage connection end m 1  of the vaporizer  12 , and the other is used as the ground voltage connection end m 2  of the vaporizer  12 . Specifically, if the vaporizer  12  is inserted into the battery rod  11  rightly, the power supply voltage connection end m 1  of the vaporizer  12  is connected to the power supply voltage connection end n 1  of the battery rod  11 , and the ground voltage connection end m 2  of the vaporizer  12  is connected to the ground voltage connection end n 2  of the battery rod. If the vaporizer  12  is inserted into the battery rod  11  reversely, the power supply voltage connection end m 1  of the vaporizer  12  is connected to the ground voltage connection end n 2  of the battery rod  11 , and the ground voltage connection end m 2  of the vaporizer  12  is connected to the power supply voltage connection end n 1  of the battery rod  11 . 
     In this embodiment, a switch module  124 , also the switch module Q 3  in  FIG.  4    and  FIG.  5   , includes a third switch M 3  and a fourth switch M 4 , where the third switch M 3  includes a first channel end, a second channel end, and a control end, and the fourth switch M 4  includes a first channel end, a second channel end, and a control end. Specifically, the control ends of the third switch M 3  and the fourth switch M 4  are connected as a control end of the switch module  124 , and are connected to the drive end P 3  of the second control chip  121 . The second channel end of the third switch M 3  and the second channel end of the fourth switch M 4  are connected, and the first channel end of the third switch M 3  and the first channel end of the fourth switch M 4  are respectively used as a first channel end and a second channel end of the switch module  124  and are respectively connected to the first input end and the second input end of the vaporizer. Further, the first channel end of the third switch M 3  is connected to the ground voltage connection end m 2  of the vaporizer  12 , and the first channel end of the fourth switch M 4  is connected to the power supply voltage connection end m 1  of the vaporizer  12 . 
     In another embodiment, the switch module  124  further includes a second resistor R 2 , and the second resistor R 2  includes the first end and the second end, where the first end of the second resistor R 2  is connected to the control ends of the third switch M 3  and the fourth switch M 4 , and the second end of the second resistor R 2  is connected to the ground voltage output end GND. 
     In a specific embodiment, the third switch M 3  and the fourth switch M 4  are NMOSFETs. In this embodiment, drains of the third switch M 3  and the fourth switch M 4  are connected to implement the turn-on and turn-off of the circuit. It can prevent the voltage from being clamped to the ground voltage through body diodes of the third switch M 3  and the fourth switch M 4  when the vaporizer  12  is inserted into the battery rod  11  rightly or reversely. 
     Specifically, when the battery rod  11  operates in the data sending period L 2 , if the vaporizer  12  is inserted into the battery rod  11  rightly, that is, the power supply voltage connection end m 1  of the vaporizer  12  is connected to the power supply voltage connection end n 1  of the battery rod  11  and the ground voltage connection end m 2  of the vaporizer  12  is connected to the ground voltage connection end n 2  of the battery rod, voltages of the control ends (gates) of the third switch M 3  and the fourth switch M 4  are at a low level. In this case, both the third switch M 3  and the fourth switch M 4  are turned off, and the voltage reaches the first channel end (source) of the fourth switch M 4  first. Since the fourth switch M 4  has a body diode, the voltage may reach a cathode from an anode of the body diode, and reach the third switch M 3 . However, since the body diode of the third switch M 3  is opposite to that of the fourth switch M 4 , the voltage cannot pass through the third switch M 3 , so that the switch module  124  can be turned off. If the vaporizer  12  is inserted into the battery rod  11  reversely, that is, the power supply voltage connection end m 1  of the vaporizer  12  is connected to the ground voltage connection end n 2  of the battery rod  11  and the ground voltage connection end m 2  of the vaporizer  12  is connected to the power supply voltage connection end n 1  of the battery rod  11 , voltages of the control ends (gates) of the third switch M 3  and the fourth switch M 4  are at a low level. In this case, both the third switch M 3  and the fourth switch M 4  are turned off, and the voltage reaches the first channel end (source) of the third switch M 3  first. Since the third switch M 3  has a body diode, the voltage may reach a cathode from an anode of the body diode, and reach the fourth switch M 4 . However, since the body diode of the third switch M 3  is opposite to that of the fourth switch M 4 , the voltage cannot pass through the fourth switch M 4 , so that the switch module  124  can be turned off. 
     Specifically, when the battery rod  11  operates in the feedback data receiving period L 4 , if the vaporizer  12  is inserted into the battery rod  11  rightly, that is, the power supply voltage connection end m 1  of the vaporizer  12  is connected to the power supply voltage connection end n 1  of the battery rod  11  and the ground voltage connection end m 2  of the vaporizer  12  is connected to the ground voltage connection end n 2  of the battery rod, voltages of the control ends (gates) of the third switch M 3  and the fourth switch M 4  are at a high level. A voltage difference Vgs between the control end (gate) and the first channel end (source) of the third switch M 3  is greater than a threshold voltage. In this case, the third switch M 3  is turned on first, and the drain of the fourth switch M 4  is turned on, and then connected to the ground voltage output end GND. The voltage of the first channel end (source) of the fourth switch M 4  is clamped to Vsd by the body diode. When a voltage difference Vgs between the gate and the source of the fourth switch M 4  is greater than the threshold voltage, the fourth switch M 4  is also turned on, so that the switch module  124  is turned on. If the vaporizer  12  is inserted into the battery rod  11  reversely, that is, the power supply voltage connection end m 1  of the vaporizer  12  is connected to the ground voltage connection end n 2  of the battery rod  11  and the ground voltage connection end m 2  of the vaporizer  12  is connected to the power supply voltage connection end n 1  of the battery rod  11 , voltages of the control ends (gates) of the third switch M 3  and the fourth switch M 4  are at a high level. A voltage difference Vgs between the control end (gate) and the first channel end (source) of the fourth switch M 4  is greater than the threshold voltage. In this case, the fourth switch M 4  is turned on first, and the drain of the third switch M 3  is turned on, and then connected to the ground voltage output end GND. The voltage of the first channel end (source) of the third switch M 3  is clamped to Vsd by the body diode. When a voltage difference Vgs between the gate and the source of the third switch M 3  is greater than the threshold voltage, the third switch M 3  is also turned on, so that the switch module  124  is turned on. 
     Specifically, if only the third switch M 3  exists in the switch module  124 , when the vaporizer  12  is inserted into the battery rod  11 , the third switch M 3  can be normally turned off or turned on. However, when the vaporizer is inserted into the battery rod  11  reversely, the body diode of the third switch M 3  directly conducts the ground voltage connection end m 2  of the vaporizer  12  to the ground. If only the fourth switch M 4  exists in the switch module  124 , when the vaporizer  12  is inserted into the battery rod  11 , the fourth switch M 4  can be normally turned off or turned on. However, when the vaporizer is inserted into the battery rod  11  reversely, the body diode of the fourth switch M 4  directly conducts the power supply voltage connection end m 1  of the vaporizer  12  to the ground. As a result, there is a problem that the body diode is clamped to the ground voltage output end GND, resulting in the failure of the circuit. 
     In this embodiment, the level exchange module  125  includes a rectifying circuit  126 . The rectifying circuit  126  includes a first path, a second path, a power supply voltage output end VCC, and a ground voltage output end GND, where the first path and the second path are connected in parallel and are respectively arranged between the power supply voltage output end VCC and the ground voltage output end GND, the first path is connected to the first input end (the first input end is the power supply voltage connection end m 1  of the vaporizer  12 ), and the second path is connected to the second input end (the second input end is the ground voltage connection end m 2  of the vaporizer  12 ).

     Specifically, the first control unit  128  includes: a fourth resistor R 4 , a third diode D 3 , and a second capacitor C 2 . The first end of the fourth resistor R 4  is connected to the second input end, and the second end of the fourth resistor R 4  is connected to the ground voltage output end GND. The first end of the third diode D 3  is connected to the second input end, and the second end of the third diode D 3  is connected to the ground voltage output end GND. The first end of the second capacitor C 2  is connected to the second end of the fourth resistor R 4 , and the second end of the second capacitor C 2  is connected to the ground voltage output end GND. 
     The second control unit  127  includes: a third resistor R 3 , a second diode D 2 , and a third capacitor C 3 . The first end of the third resistor R 3  is connected to the first input end, and the second end of the third resistor R 3  is connected to the ground voltage output end GND. The first end of the second diode D 2  is connected to the first input end, and the second end of the second diode D 2  is connected to the ground voltage output end GND.

     The second path includes: a fifth switch M 5  and a sixth switch M 6 . The fifth switch M 5  includes a first channel end, a second channel end, and a control end, the control end of the fifth switch M 5  is connected to the first end of the third capacitor C 3 , the first channel end of the fifth switch M 5  is connected to the ground voltage output end GND, and the second channel end of the fifth switch M 5  is connected to the second input end. The sixth switch M 6  includes a first channel end, a second channel end, and a control end, the control end of the sixth switch M 6  is connected to the first end of the third capacitor C 3 , the first channel end of the sixth switch M 6  is connected to the power supply voltage output end VCC, and the second channel end of the sixth switch M 6  is connected to the second input end. 
     Specifically, in an embodiment, the second control chip  121  in the vaporizer  12  further includes a ground voltage output end GND, and the ground voltage output end GND in the rectifying circuit  126  is connected to the ground voltage output end GND of the second control chip  121 . Specifically, the power supply voltage output end VCC in the rectifying circuit  126  is connected to the power supply end VCC of the second control chip  121 . 
     Specifically, when the vaporizer  12  is inserted into the battery rod  11  rightly, the power supply voltage connection end m 1  of the vaporizer  12  is connected to the power supply voltage connection end n 1  of the battery rod  11  and receives the power supply voltage output end VCC; and the ground voltage connection end m 2  of the vaporizer  12  is connected to the ground voltage connection end n 2  of the battery rod  11  and receives the ground voltage output end GND. In this case, since the ground voltage connection end m 2  of the vaporizer  12  is connected to the ground voltage connection end n 2  of the battery rod  11 , the second control unit  127  controls the fifth switch M 5  in the second path to be turned on and the sixth switch M 6  to be turned off, and the ground voltage connection end m 2  is connected to the ground voltage output end GND through the fifth switch M 5 . Since the power supply voltage connection end m 1  of the vaporizer  12  is connected to the power supply voltage connection end n 1  of the battery rod  11 , the first control unit  128  controls the seventh switch M 7  in the first path to be turned on and the eighth switch M 8  to be turned off, and the power supply voltage connection end m 1  is connected to the power supply voltage output end VCC through the seventh switch M 7 . 
     When the vaporizer  12  is reversely inserted into the battery rod  11 , the power supply voltage connection end m 1  of the vaporizer  12  is connected to the ground voltage connection end n 2  of the battery rod  11  and receives the ground voltage output end GND; and the ground voltage connection end m 2  of the vaporizer  12  is connected to the power supply voltage connection end n 1  of the battery rod  11  and receives the power supply voltage VDD. In this case, since the ground voltage connection end m 2  of the vaporizer  12  is connected to the power supply voltage connection end n 1  of the battery rod  11 , the second control unit  127  controls the sixth switch M 6  in the second path to be turned on and the fifth switch M 6  to be turned off, and the ground voltage connection end m 2  is connected to the power supply voltage output end VCC through the sixth switch M 6 . Since the power supply voltage connection end m 1  of the vaporizer  12  is connected to the ground voltage connection end n 2  of the battery rod  11 , the first control unit  128  controls the eighth switch M 8  in the first path to be turned on and the seventh switch M 7  to be turned off, and the power supply voltage connection end m 1  is connected to the ground voltage output end GND through the eighth switch M 8 . 
     Specifically, when the vaporizer  12  is inserted into the battery rod  11  rightly, the power supply voltage connection end m 1  is connected to a positive voltage, the third capacitor C 3  in the second control unit  127  is charged, the fifth switch M 5  is turned on, and the sixth switch M 6  is turned off. At a moment when the level of the power supply voltage connection end m 1  changes from high to low, the third capacitor C 3  cannot discharge through the second diode D 2 , and can only discharge slowly through the third resistor R 3 . The gates of the sixth switch M 6  and the fifth switch M 5  are maintained at a high level, the fifth switch M 5  is kept in an on state, and the sixth switch M 6  is kept in an off state, until the fifth switch M 5  is turned off when the gate voltage thereof is lower than the threshold voltage. The second diode D 2 , the third resistor R 3 , and the third capacitor C 3  are grounded, and thus are always in a low level state. In addition, when the vaporizer  12  is inserted into the battery rod  11  rightly, the level of the power supply voltage connection end m 1  is instantaneously high, and the seventh switch M 7  in the first path is turned on. The eighth switch M 8  is turned off instantaneously. Moreover, at a moment when the level of the power supply voltage connection end m 1  changes from high to low, the seventh switch M 7  and the eighth switch M 8  are turned off simultaneously. In this embodiment, the first control unit  128  and the second control unit  127  can always keep the fifth switch M 5  in an on state for a required time (for example, about 30 ms, where the required time is determined by the values of the third resistor R 3  and the third capacitor C 3 ) when the vaporizer  12  is inserted rightly. Without the first control unit  128  and the second control unit  127 , when the power supply voltage connection end m 1  is switched from a high level to a low level, the fifth switch M 5 , the sixth switch M 6 , the seventh switch M 7 , and the eighth switch M 8  are turned off simultaneously. As a result, there is a voltage difference between the gate and the source of the third switch M 3  and the fourth switch M 4  of the switch module  124 , and then the third switch M 3  and the fourth switch M 4  are turned on. Consequently, the communication between the vaporizer  12  and the battery rod  11  is interrupted. 
     Specifically, when the vaporizer  12  is inserted into the battery rod  11  reversely, the ground voltage connection end m 2  is connected to a positive voltage, the second capacitor C 2  in the first control unit  128  is charged, the eighth switch M 8  is turned on, and the seventh switch M 7  is turned off. At a moment when the level of the ground voltage connection end m 2  changes from high to low, the second capacitor C 2  cannot discharge through the third diode D 3 , and can only discharge slowly through the fourth resistor R 4 . The gates of the seventh switch M 7  and the eighth switch M 8  are maintained at a high level, the eighth switch M 8  is kept in an on state, and the seventh switch M 7  is kept in an off state, until the eighth switch M 8  is turned off when the gate voltage thereof is lower than the threshold voltage. The third diode D 3 , the fourth resistor R 4 , and the second capacitor C 2  are grounded, and thus are always in a low level state. In addition, when the vaporizer  12  is inserted into the battery rod  11  reversely, the level of the ground voltage connection end m 2  is instantaneously high, and the sixth switch M 6  in the second path is turned on. The fifth switch M 5  is turned off instantaneously. Moreover, at a moment when the level of the ground voltage connection end m 2  changes from high to low, the fifth switch M 5  and the sixth switch M 6  are turned off simultaneously. In this embodiment, the first control unit  128  and the second control unit  127  can always keep the sixth switch M 6  in an on state for a required time (for example, about 30 ms, where the required time is determined by the values of the fourth resistor R 4  and the second capacitor C 2 ) when the vaporizer  12  is inserted reversely. Without the first control unit  128  and the second control unit  127 , when the power supply voltage connection end m 1  is switched from a high level to a low level, the fifth switch M 5 , the sixth switch M 6 , the seventh switch M 7 , and the eighth switch M 8  are turned off simultaneously. As a result, there is a voltage difference between the gate and the source of the third switch M 3  and the fourth switch M 4  of the switch module  124 , and then the third switch M 3  and the fourth switch M 4  are turned on. Consequently, the communication between the vaporizer  12  and the battery rod  11  is interrupted. 
       FIG.  7    is a schematic structural diagram of a first embodiment of an electronic vaporization device according to the present invention. In this embodiment, when the vaporizer  12  is inserted into the battery rod  11 , the power supply voltage connection end n 1  of the battery rod  11  is connected to the power supply voltage connection end m 1  of the vaporizer  12 , and the ground voltage connection end n 2  of the battery rod  11  is connected to the ground voltage connection end m 2  of the vaporizer  12 . 
     Specifically, the battery rod  11  in this embodiment includes the battery rod shown in  FIG.  1   , and details are not described herein again. The vaporizer  12  in this embodiment includes the vaporizer  12  shown in any of the foregoing embodiments in  FIG.  4    and  FIG.  5   , and details are not described herein again. 
     In the electronic vaporization device shown in this embodiment, the vaporizer  12  is inserted into the battery rod  11 , and the battery rod  11  supplies power to the vaporizer  12  and sends data to the vaporizer  12 . After receiving the sending data sent by the battery rod  11 , the vaporizer  12  feeds back identification information to the battery rod  11 , for the battery rod  11  to use, according to the identification information, a corresponding power to drive the vaporizer  12 , to avoid the mixing of the battery rod  11  and the vaporizer  12 . Specifically, if the battery rod  11  and the vaporizer  12  are mixed, a difference in driving powers causes the odor of smoke or the amount of smoke to be too small or too large. In another example, a difference in resistance values of the heating wire leads to cases such as overcurrent protection and no smoke generation. Through the method of the present invention, the battery rod  11  and the vaporizer  12  can be identified with each other, and the battery rod  11  can use the power matching the vaporizer  12  to drive the vaporizer  12 , thereby improving the user experience.
