Specifically, the battery assembly includes a positive voltage terminal n1, a negative voltage terminal n2 and a control circuit 10, and the atomizer includes a first connection terminal m1, a second connection terminal m2 and a driving circuit 20. When the atomizer is inserted into the battery assembly and the control circuit 10 is connected, the positive voltage terminal n1 of the battery assembly is connected to the first connection terminal m1 of the atomizer, and the negative voltage terminal n2 of the battery assembly is connected to the second connection terminal m2 of the atomizer, so as to power the atomizer by the battery assembly.

[0056] Please refer to Figure 3 , in order to overcome the interference of external signals and improve the stability of communication signals. In the present application, the battery assembly is connected to the atomizer through the positive voltage terminal n1 and the negative voltage terminal n2 to power the atomizer, and the control circuit 10 is connected to at least one of the positive voltage terminal n1 and the negative voltage terminal n2, and the connected positive voltage terminal n1 or negative voltage terminal n2 is used as a communication terminal to realize the transmission of communication signals with the atomizer. Among them, the communication signal is a plurality of spike signals superimposed on the basis of the corresponding working voltage to be output by the communication terminal or a pulse width modulation signal generated by modulating the corresponding working voltage to be output by the communication terminal.

[0057] Further, the positive voltage terminal n1 of the battery assembly is connected to the first connection terminal m1 of the atomizer, and the negative voltage terminal n2 of the battery assembly is connected to the second connection terminal m2 of the atomizer. The battery assembly realizes the transmission of the first communication signal with the atomizer through the positive voltage terminal n1, and the atomizer realizes the transmission of the second communication signal with the battery assembly through the first connection terminal m1, so as to realize the communication between the battery assembly and the atomizer, and further determine whether the battery assembly and the atomizer are matched.

[0058] It can be understood that, in the embodiment, the control circuit 10 is connected to the positive voltage end n1, and the positive voltage end n1 is used as a communication end to realize communication signal transmission with the atomizer. The communication signal includes a first communication signal and a second communication signal. The first communication signal is a communication signal sent by the control circuit 10 to the atomizer through the communication end, and the second communication signal is a communication signal fed back by the atomizer and collected by the control circuit 10 through the communication end.

[0059] The first communication signal includes a plurality of first spike signals superimposed on the corresponding working voltage required to be output by the positive voltage end n1 as the communication end, or a first pulse width modulation signal generated by modulating the corresponding working voltage required to be output by the positive voltage end n1 as the communication end. The plurality of first spike signals are used to transmit digital communication signals, or the logic high level in the first pulse width modulation signal corresponds to the corresponding working voltage required to be output by the positive voltage end n1. The logic low level pulse corresponding to the logic low level in the first pulse width modulation signal is used to transmit digital communication signals.

[0060] The second communication signal includes a plurality of second spike signals superimposed by the atomizer on the basis of the corresponding working voltage required to be output by the positive voltage end n1 as the communication end. The plurality of second spike signals fed back are used to transmit digital communication signals.

[0061] Specifically, in an embodiment, the first communication signal is a plurality of first spike signals superimposed on the basis of the corresponding working voltage output by the positive voltage end n1 as the communication end. The plurality of first spike signals are used to transmit digital communication signals. The second communication signal is a plurality of second spike signals superimposed by the atomizer on the basis of the corresponding working voltage required to be output by the positive voltage end n1 as the communication end. The plurality of second spike signals are used to transmit digital communication signals.

[0062] The plurality of first spike signals are used to transmit digital communication signals or the plurality of second spike signals are used to transmit digital communication signals. The specific representation is as follows:

[0063] First, referring to Figure 4 and Figure 5 The time interval between the two adjacent first spike signals or the two adjacent second spike signals respectively represents different logic data values.

[0064] Second, referring to Figure 6 The number of first spike signals or second spike signals in a preset time period respectively represents different logic data values.

[0065] Please refer to Figure 4For the first case, the time interval between two adjacent first peak signals or two adjacent second peak signals meets the first preset time interval, representing the logic data value "00"; the time interval between two adjacent first peak signals or two adjacent second peak signals meets the second preset time interval and is an odd number of second preset time intervals, representing the logic data value "01"; the time interval between two adjacent first peak signals or two adjacent second peak signals meets the second preset time interval and is an even number of second preset time intervals, representing the logic data value "0"; the time interval between two adjacent first peak signals or two adjacent second peak signals meets the third preset time interval, representing the logic data value "1".

[0066] Further, the first preset time interval, the second preset time interval and the third preset time interval are in the ratio of 2:1.5:1.

[0067] Please refer to Figure 4 In the embodiment, the above is illustrated by taking data as an example. If the first preset time interval is 128uS, the time interval between two adjacent first peak signals or two adjacent second peak signals represents the logic data value "00"; if the second preset time interval is 96uS and is an odd number of times, the time interval between two adjacent first peak signals or two adjacent second peak signals represents the logic data value "01"; if the second preset time interval is 96uS and is an even number of times, the time interval between two adjacent first peak signals or two adjacent second peak signals represents the logic data value "0"; if the third preset time interval is 64uS, the time interval between two adjacent first peak signals or two adjacent second peak signals represents the logic data value "1", wherein 128:96:64 is in the ratio of 2:1.5:1. Such design can effectively reduce the interference of external signals on the first communication signal and the second communication signal, and make the battery assembly and the atomizer match better.

[0068] Please refer to Figure 5 For the first case, the time interval between two adjacent first peak signals or two adjacent second peak signals meets the first preset time interval, representing the logic data value "00"; the time interval between two adjacent first peak signals or two adjacent second peak signals meets the second preset time interval and is an odd number of second preset time intervals, representing the logic data value "01"; the time interval between two adjacent first peak signals or two adjacent second peak signals meets the second preset time interval and is an even number of second preset time intervals, representing the logic data value "0"; the time interval between two adjacent first peak signals or two adjacent second peak signals meets the third preset time interval, representing the logic data value "1".

[0069] Further, the fourth preset time intervals of any two data bits of the communication signal are equal or unequal; the fifth preset time intervals of any two data bits of the communication signal are equal or unequal.

[0070] Please refer toFigure 5 In the embodiment, the first bit of the custom communication signal corresponds to a preset time interval of 100uS, representing a logic data value of "0", and the first bit of the custom communication signal corresponds to a preset time interval of 200uS, representing a logic data value of "1".

[0071] The second bit of the custom communication signal corresponds to a preset time interval of 30uS, representing a logic data value of "0", and the second bit of the custom communication signal corresponds to a preset time interval of 60uS, representing a logic data value of "1".

[0072] The third bit of the custom communication signal corresponds to a preset time interval of 50uS, representing a logic data value of "0", and the third bit of the custom communication signal corresponds to a preset time interval of 10uS, representing a logic data value of "1".

[0073] The fourth bit of the custom communication signal corresponds to a preset time interval of 200uS, representing a logic data value of "0", and the fourth bit of the custom communication signal corresponds to a preset time interval of 600uS, representing a logic data value of "1". The same custom is performed until the transmission data bit of the communication signal is defined.

[0074] Assuming that the preset transmission data of the communication signal is "0001110001010", the first data bit is a logic data value of "0", and the time interval between the first adjacent two first spike signals or the first adjacent two second spike signals is 100uS; the second data bit is a logic data value of "0", and the time interval between the second adjacent two first spike signals or the second adjacent two second spike signals is 30uS; the third data bit is a logic data value of "0", and the time interval between the third adjacent two first spike signals or the third adjacent two second spike signals is 50uS; the fourth data bit is a logic data value of "1", and the time interval between the fourth adjacent two first spike signals or the fourth adjacent two second spike signals is 600uS; and the same is performed until the transmission data of the communication signal is completed. This method can be customized by the user, effectively reducing the interference of external signals on the first communication signal and the second communication signal, making the matching of the battery assembly and the atomizer more optimal, and effectively improving the safety of communication between the battery assembly and the atomizer.

[0075] Please refer to Figure 6 Further explanation of the second case, the number of first spike signals or second spike signals in the preset time period meets the preset first number range, representing a logic data value of "0"; the number of first spike signals or second spike signals in the preset time period meets the preset second number range, representing a logic data value of "1".

[0076] In the embodiment, it can be understood that the above description is illustrated by taking the data as an example, assuming that the preset transmission data of the communication signal is "0001110001010", and the preset transmission time of each data bit is 100uS. In the preset transmission time, 80 spike signals are sent to represent the logic data value "0"; in the preset transmission time, 40 spike signals are sent to represent the logic data value "1". That is, when the first logic data value "0" is transmitted, 80 spike signals are sent to the atomizer or the battery assembly within 100uS; when the second logic data value "0" is transmitted, 80 spike signals are sent to the atomizer or the battery assembly within 100uS, and so on, until the transmission data of the communication signal is completed.

[0077] In addition, in the embodiment, the number of the first spike signals or the second spike signals received by the atomizer or the battery assembly is allowed to have an error of 20%. That is, when the atomizer receives the first spike signals or the battery assembly receives the second spike signals, if the received first spike signals or the second spike signals are 64-96, it can also represent the data value "0", and if the received first spike signals or the second spike signals are 32-48, it can also represent the data value "1". In this way, the anti-interference ability of the communication signal between the battery assembly and the atomizer is further improved, and the communication between the battery assembly and the atomizer is realized.

[0078] Specifically, in another embodiment, the first communication signal is a first pulse width modulation signal, the logic high level in the first pulse width modulation signal corresponds to the corresponding working voltage that needs to be output by the positive voltage end n1, and the logic low level pulse corresponding to the logic low level in the first pulse width modulation signal is used to transmit the digital communication signal; the second communication signal is a plurality of second spike signals superimposed by the atomizer on the basis of the corresponding working voltage that needs to be output by the positive voltage end n1 of the communication end, and the plurality of second spike signals are used to transmit the digital communication signal. It can be understood that the first communication signal can also be a plurality of first spike signals superimposed on the basis of the corresponding working voltage that needs to be output by the positive voltage end n1 of the communication end, and the plurality of first spike signals are used to transmit the digital communication signal, and the second communication signal is the first pulse width modulation signal described above.

[0079] The logic low level pulse corresponding to the logic low level in the first pulse width modulation signal is used to transmit the digital communication signal, and specifically:

[0080] Firstly, referring to Figure 7 and Figure 8 , the time interval between the adjacent two logic low level pulses respectively represents different logic data values;

[0081] Secondly, referring to Figure 9 , the number of the logic low level pulses within the preset time period respectively represents different logic data values.

[0083] Further, the first preset time interval, the second preset time interval and the third preset time interval are in the ratio of 2:1.5:1.

[0084] Please see Figure 7 In this embodiment, the above is illustrated by taking the data as an example. If the first preset time interval is 128uS, the time interval between the two adjacent logic low level pulses represents the logic data value "00"; if the second preset time interval is 96uS and the odd number of the second preset time interval appears, the time interval between the two adjacent logic low level pulses represents the logic data value "01"; if the second preset time interval is 96uS and the even number of the second preset time interval appears, the time interval between the two adjacent logic low level pulses represents the logic data value "0"; if the third preset time interval is 64uS, the time interval between the two adjacent logic low level pulses represents the logic data value "1", wherein 128:96:64 conforms to 2:1.5:1. Such design can effectively reduce the interference of external signals on the first communication signal, and make the battery assembly and the atomizer match better.

[0086] Further, the fourth preset time interval of any two data bits of the communication signal is equal or unequal; the fifth preset time interval of any two data bits of the communication signal is equal or unequal.

[0087] Please see Figure 8In the embodiment, the above is illustrated by taking the data as an example. The preset time interval corresponding to the first data bit of the self-defined communication signal is 100uS, representing the logic data value "0". The preset time interval corresponding to the first data bit of the self-defined communication signal is 200uS, representing the logic data value "1".

[0088] The preset time interval corresponding to the second data bit of the self-defined communication signal is 30uS, representing the logic data value "0". The preset time interval corresponding to the second data bit of the self-defined communication signal is 60uS, representing the logic data value "1".

[0089] The preset time interval corresponding to the third data bit of the self-defined communication signal is 50uS, representing the logic data value "0". The preset time interval corresponding to the third data bit of the self-defined communication signal is 10uS, representing the logic data value "1".

[0090] The preset time interval corresponding to the fourth data bit of the self-defined communication signal is 200uS, representing the logic data value "0". The preset time interval corresponding to the fourth data bit of the self-defined communication signal is 600uS, representing the logic data value "1". In this way, the transmission data bit of the communication signal is defined.

[0091] Suppose the transmission data of the communication signal is "0001110001010", the first data bit is the logic data value "0", and the time interval between the first two adjacent logic low level pulses is 100uS. The second data bit is the logic data value "0", and the time interval between the second two adjacent logic low level pulses is 30uS. The third data bit is the logic data value "0", and the time interval between the third two adjacent logic low level pulses is 50uS. The fourth data bit is the logic data value "1", and the time interval between the fourth two adjacent logic low level pulses is 600uS. In this way, the transmission data of the communication signal is completed. This method can be customized by the user, effectively reducing the interference of external signals on the first communication signal and the second communication signal, making the matching of the battery assembly and the atomizer more optimal, and effectively improving the safety of communication between the battery assembly and the atomizer.

[0092] Please refer to Figure 9 For the second case, the number of logic low level pulses in the preset time period meets the preset first number range, representing the logic data value "0". The number of logic low level pulses in the preset time period meets the preset second number range, representing the logic data value "1".

[0093] In the embodiment, it can be understood that the above is described by taking the data as an example. The communication signal transmission time is divided into N transmission time periods, and the number of logic low level pulses in each transmission time period is used to represent the logic data value "0" or "1". Assuming that the first transmission time period is 5 ms, if the number of logic low level pulses is 10, it represents the logic data value "1", and if the number of logic low level pulses is 20, it represents the logic data value "0"; assuming that the second transmission time period is 8 ms, if the number of logic low level pulses is 30, it represents the logic data value "1", and if the number of logic low level pulses is 5, it represents the logic data value "0"; and so on, until the transmission data of the communication signal is completed. In this way, the anti-interference ability of the communication signal between the battery assembly and the atomizer is further improved, and the communication between the battery assembly and the atomizer is realized.

The signal receiving unit 115 can be an operational amplifier or a comparator.

[0103] Please refer to Figure 11 , the circuit structure schematic diagram of the second embodiment of the battery assembly of the present application. Compared with the structure schematic diagram of the first embodiment, the distinguishing features of the present embodiment are that the control circuit 10 further comprises a feedback signal receiving unit 15, the feedback signal receiving unit 15 comprises a signal amplification processing unit 151, the controller 11 comprises a comparator or an external interrupt IO port unit 111 and a data processing unit 112, wherein the data processing unit 112 is connected with the comparator or the external interrupt IO port unit 111, the comparator or the external interrupt IO port unit 111 is connected with the signal amplification processing unit 151 in the feedback signal receiving unit 15, and the feedback signal receiving unit 15 is connected with the positive voltage end n1 as a communication end.

[0105] Please refer to Figure 12 , the circuit structure schematic diagram of the third embodiment of the battery assembly of the present application. The battery assembly comprises a positive voltage end n1, a negative voltage end n2, and a control circuit 10, wherein the control circuit 10 comprises a controller 11 and a first switch 12, and the controller 11 comprises a first control end f1; the first switch 12 comprises a first passage end, a second passage end, and a control end; the first passage end of the first switch 12 is connected with a voltage source Vbat; the control end of the first switch 12 is connected with the first control end f1 of the controller 11; and the second passage end of the first switch 12 is connected with a communication end. Specifically, the control end of the first switch 12 is turned on / off according to the first control signal of the first control end f1 of the controller 11, so as to turn on / off the path between the voltage source Vbat and the communication end, so that the controller 11 provides a corresponding working voltage to the communication end through the first switch 12.

The communication signal sending unit 14 comprises a second switch 13, which is controlled by the controller 11 to be turned on / off, so as to superimpose the first spike signal on the corresponding working voltage output by the positive voltage end n1 of the communication end. Specifically, the second switch 13 is connected to the communication end, and when the first switch 12 is turned on to enable the voltage source Vbat to provide the corresponding working voltage to the communication end, the turning on / off of the second switch 13 superimposes the first spike signal on the corresponding working voltage output by the communication end, so as to generate the first communication signal.

[0107] Further, the communication signal sending unit 14 further comprises a resistor R3 and a first capacitor C3. The resistor R3 comprises a first end and a second end. The first capacitor C3 comprises a first end and a second end. The second switch 13 comprises a first path end, a second path end and a control end.

[0108] Specifically, the first end of the resistor R3 is connected to the first end of the first capacitor C3 and the positive voltage end n1 of the communication end. The second end of the resistor R3 is connected to the second end of the first capacitor C3 and the first path end of the second switch 13. The second path end of the second switch 13 is grounded.

[0109] Specifically, when the second switch 13 is switched from the first state to the second state, the first spike signal is a down spike signal. When the second switch 13 is switched from the second state to the first state, the first spike signal is an up spike signal. If the first state is the on state, the second state is the off state. If the first state is the off state, the second state is the on state.

[0110] Specifically, in the embodiment, the second switch 13 is an N-type switch transistor. When the second switch 13 is switched from the off state to the on state, the first spike signal is a down spike signal. When the second switch 13 is switched from the on state to the off state, the first spike signal is an up spike signal.

[0111] Further, the feedback signal receiving unit 15 is connected to the controller 11 and the positive voltage terminal n1 as the communication terminal, to detect the second communication signal fed back on the communication terminal, and feed back the second communication signal to the controller 11. Wherein, in the state that the first switch 12 is turned on to make the voltage source Vbat provide the corresponding working voltage to the communication terminal, the second communication signal is to control the third switch 23 in the atomizer to be turned on / off, and the second spike signal is superimposed on the basis of the corresponding working voltage output by the communication terminal. Specifically, the feedback signal receiving unit 15 includes a signal amplification processing unit 151, which amplifies and processes the detected second communication signal fed back on the communication terminal and then transmits it to the controller 11.

[0112] Further, the controller 11 includes a comparator or external interrupt IO port unit 111 and a data processing unit 112. Wherein, the data processing unit 112 is connected to the comparator or external interrupt IO port unit 111, the comparator or external interrupt IO port unit 111 is connected to the signal amplification processing unit 151 in the feedback signal receiving unit 15, and the feedback signal receiving unit 15 is connected to the positive voltage terminal n1 as the communication terminal.

[0113] Specifically, the feedback signal receiving unit 15 detects the second communication signal fed back on the communication terminal through the positive voltage terminal n1 as the communication terminal, and the detected second communication signal is amplified and processed by the signal amplification processing unit 151 in the feedback signal receiving unit 15, and then transmitted to the data processing unit 112 to identify the digital communication signal in the second communication signal.

[0114] In an embodiment, in combination with Figure 4 The above content is further understood by the waveform shown in the figure. For example, the preset transmission data is "0001110001010", the controller 11 internally generates a clock signal, the controller 11 encodes the preset transmission data according to the clock signal to generate an encoded signal, a plurality of encoded signals are combined to form a transmission waveform, and the controller 11 outputs the transmission waveform to the second switch 13, so that the rising edge in the transmission waveform triggers the second switch 13 to be turned on / off, so as to superimpose the first spike signal on the basis of the corresponding working voltage output by the communication terminal, and then generate the first communication signal. Wherein, the time interval between the adjacent two spike signals in the first communication signal represents the digital communication signal, and the specific representation is described in the function module of the first embodiment, which will not be repeated here. In this embodiment, the clock speed of the clock signal is 32uS, and the bit transmission speed is 64uS.

[0115] Please refer to Figure 4In the BMC encoding of the preset transmission data, when the data bit represents the logical data value "0", the waveform of the data bit does not occur inversion in the time interval occupied by the data bit; when the data bit represents the logical data value "1", the waveform of the data bit occurs inversion once in the time interval occupied by the data bit; and the starting level of the subsequent data bit in the encoding signal is the opposite level of the ending level of the previous data bit.

[0116] Further, as shown in Figure 4 , in the BMC encoding of the preset transmission data, the rising edge of the waveform of the encoding signal triggers the on / off of the second switch 13, in order to avoid the last bit of the transmission data being "0" and the logic low level pulse in the transmission waveform, resulting in no falling edge of the transmission waveform to trigger the on / off of the second switch 13 and loss of the preset transmission data. Therefore, "0" is automatically supplemented as an auxiliary bit at the end of the encoding signal, preventing loss of data.

[0117] Further, as shown in Figure 4 , the VIC represents the minimum working voltage of the driving circuit 20 of the atomizer, and the minimum voltage value of the lower peak signal in the first communication signal is greater than the minimum working voltage of the atomizer, so that when the atomizer is connected in communication with the battery assembly, the battery assembly supplies power to the atomizer through the first communication signal.

[0118] In another embodiment, the above is further understood in combination with Figure 13 the waveform shown, Figure 13 the waveform shown, and Figure 4 the waveform shown, the difference between the waveform shown in , in the BMC encoding of the preset transmission data, the controller 11 internally obtains the interval pulse signal according to the falling edge of the waveform after BMC encoding, and the controller 11 outputs the pulse signal to make the second switch 13 conductive / off, so as to superimpose the first peak signal on the basis of the corresponding working voltage output by the communication end, thereby generating the first communication signal. Among them, the time interval between the adjacent two peak signals in the first communication signal represents the digital communication signal.

[0119] Figure 14Fig. 4 is a schematic diagram of a circuit structure of a fourth embodiment of the battery assembly. The battery assembly comprises a positive voltage terminal n1, a negative voltage terminal n2, and a control circuit 10, which comprises a controller 11 and a first switch 12, wherein the controller 11 comprises a first control terminal f1, the first switch 12 comprises a first passage terminal, a second passage terminal, and a control terminal, the first passage terminal of the first switch 12 is connected to a voltage source, the control terminal of the first switch 12 is connected to the first control terminal f1 of the controller 11, and the second passage terminal of the first switch 12 is connected to a communication terminal. Specifically, the control terminal of the first switch 12 is turned on / off according to a first control signal of the first control terminal f1 of the controller 11, so as to turn on / off a path between the voltage source and the communication terminal, so that the controller 11 provides a corresponding working voltage to the communication terminal through the first switch 12.

[0120] Further, the controller 11 further comprises a second switch 13, a communication signal output terminal f2, and a communication signal receiving terminal f3, wherein the second switch 13 is connected to the positive voltage terminal n1 as the communication terminal through the communication signal output terminal f2, and in a state where the first switch 12 is turned on to provide the corresponding working voltage to the communication terminal by the voltage source Vbat, the controller 11 controls the second switch 13 to be turned on / off, so as to superimpose a first spike signal on the corresponding working voltage output by the communication terminal, thereby generating a first communication signal.

[0121] The communication signal receiving terminal f3 is connected to the positive voltage terminal n1 as the communication terminal, and is used to detect a second communication signal fed back on the communication terminal, wherein the second communication signal is a corresponding working voltage output by the communication terminal of the atomizer on the basis of superimposing a second spike signal by the atomizer controlling the third switch 23 to be turned on / off. That is, the atomizer comprises a third switch 23 connected to the communication terminal, and in a state where the first switch 12 is turned on to provide the corresponding working voltage to the communication terminal by the voltage source, the third switch 23 is turned on / off on the basis of superimposing the second spike signal on the corresponding working voltage output by the communication terminal, thereby generating the second communication signal.

[0122] Wherein the plurality of first spike signals or the plurality of second spike signals are used to transmit a digital communication signal, and the specific manner is described in the first embodiment, which will not be repeated here.

[0123] Furthermore, the controller 11 also includes a signal processing unit 113, a logic processing unit 114, and a communication signal receiving terminal f3. The signal processing unit 113 is connected to the logic processing unit 114 and the communication signal receiving terminal f3. The communication signal receiving terminal f3 is connected to a positive voltage terminal n1, serving as the communication terminal, to detect the second communication signal fed back from the communication terminal. The detected second communication signal is received by the signal processing unit 113 and transmitted to the logic processing unit 114 to identify the digital communication signal in the second communication signal. Specifically, the signal processing unit 113 can be an operational amplifier or a comparator.

[0124] This can be understood as follows: when the first switch 12 is turned on to provide the corresponding working voltage to the communication terminal, the controller 11 controls the second switch 13 to turn on / off, so as to superimpose the first spike signal on the corresponding working voltage output by the communication terminal to generate the first communication signal; the communication signal receiving terminal f3 is connected to the positive voltage terminal n1 of the communication terminal to detect the second communication signal fed back on the communication terminal; after the signal processing unit 113 receives the second communication signal, it transmits it to the logic processing unit 114 to identify the digital communication signal in the second communication signal, thereby realizing the communication connection between the battery assembly and the atomizer.

[0125] In one embodiment, combined with Figure 15 The waveform shown provides a further understanding of the above content, in which, Figure 15 The waveform shown is the same as in the previous embodiment. Figure 4 The difference in the waveforms shown lies in the fact that the falling edge of the transmission waveform triggers the second switch 13 within the controller 11 to turn on / off, thereby superimposing a first spike signal onto the corresponding operating voltage output at the communication terminal to generate a first communication signal. The time interval between two adjacent spike signals in the first communication signal represents the digital communication signal; the specific representation is explained in the functional modules of the first embodiment and will not be repeated here. In this embodiment, the clock speed of the clock signal is 32µs, and the bit transmission speed is 64µs.

[0126] For details, please refer to [link / reference]. Figure 15 , Figure 15 VIC represents the minimum operating voltage of the atomizer's drive circuit 20. The minimum voltage value of the lower spike signal in the first communication signal is greater than the minimum operating voltage of the atomizer, so that when the atomizer is connected to the battery assembly for communication, the battery assembly supplies power to the atomizer through the first communication signal.

[0127] In an embodiment, the first spike signal in the first communication signal is an up spike signal or a down spike signal, wherein the up spike signal is a first voltage mutation signal formed in a direction smaller than a corresponding working voltage on the basis of the corresponding working voltage, and the down spike signal is a second voltage mutation signal formed in a direction greater than the corresponding working voltage on the basis of the corresponding working voltage.

[0128] In combination Figure 16 And Figure 17 The principle of generating the first spike signal is described. In the prior art, there are various circuits that can generate spike signals, but in this embodiment, the second switch 13 is taken as an N-type switch transistor for illustration.

[0129] Referring to Figure 16 , the equivalent model of the second switch 13 has an internal parallel connection of an inter-electrode equivalent capacitor C2 and an internal resistance R1, and the inter-electrode equivalent capacitor C2 is located between the source-drain level (DS) of the second switch 13. When the second switch 13 is switched from the off state to the on state, the inter-electrode equivalent capacitor C2 is in a charging state (short circuit) instantaneously, and the D-pole voltage of the second switch 13 is at a logic low level. When the inter-electrode equivalent capacitor C2 of the second switch 13 is full and in a saturated on state, the D-pole voltage of the second switch 13 is in a saturated working state inside the internal resistance R1, and the Vload end is at a logic high level. Therefore, when the second switch 13 is switched from the off state to the on state, a down spike will be formed on the D-pole of the second switch 13, and the first spike signal or the second spike signal will be a down spike signal.

[0130] When the second switch 13 is in the on state, the Vload end flows through the current from the internal resistance R of the second switch 13, and the inter-electrode equivalent capacitor C2 of the second switch 13 is full of electricity. When the second switch 13 is switched from the on state to the off state, not only the current flowing through the Vload on the internal resistance R1 of the second switch 13, but also the current on the internal resistance R1 caused by the discharge of the inter-electrode equivalent capacitor C2 need to be superimposed, thereby causing the voltage on the internal resistance R1 to rise, which reversely affects the rise of the Vload voltage to form an up spike. Therefore, when the second switch 13 is switched from the on state to the off state, an up spike will be formed on the D-pole of the second switch 13, and the first spike signal or the second spike signal will be an up spike signal. Figure 16 Compared with Figure 17 The difference feature is that the equivalent capacitor C2 is connected with a voltage dividing resistance R3, and the principle of generating the first spike signal is the same as that of the above Figure 15

[0131] ​Further, since the undershoot spike is a momentary short circuit of the second switch 13, the resistance value of the internal resistance R1 is very small, and thus the voltage amplitude of the generated undershoot spike is higher than the voltage amplitude of the corresponding working voltage; the overshoot spike is that the equivalent capacitor C2 between the poles of the second switch 13 is full of electricity after the second switch 13 is opened for a long time, and when the second switch 13 is closed, the resistance value is the internal resistance R1 and the Vload load resistance, so the voltage amplitude of the overshoot spike is relatively small compared with the voltage amplitude of the undershoot spike. Therefore, in the embodiment, the first communication signal selects multiple undershoot spike signals to transmit digital communication signals.

[0132] In addition, in the embodiment, the second spike signal generation principle and related settings in the second communication signal are consistent with the first spike signal generation principle and related settings in the first communication signal, and for the sake of simplicity, they will not be described here.

The atomizer comprises a first connection end m1, a second connection end m2 and a driving circuit 20, the first connection end m1 and the second connection end m2 are respectively used for connecting a battery assembly to receive the electric energy provided by the battery assembly; the driving circuit 20 connects the first connection end m1 and the second connection end m2, and the driving circuit 20 takes at least one of the first connection end m1 or the second connection end m2 as a communication end to realize the transmission of communication signals with the battery assembly; wherein the communication signal is a plurality of spike signals superimposed on the basis of the corresponding working voltage to be output on the communication end.

[0134] Further, the battery assembly takes the positive voltage end n1 as the communication end of the battery assembly, the atomizer takes the first connection end m1 or the second connection end m2 connected with the positive voltage end n1 as the communication end to realize the communication with the battery assembly; the communication signal comprises a first communication signal and a second communication signal. Wherein the first communication signal is the communication signal sent by the control circuit 10 to the atomizer through the communication end, and the second communication signal is the communication signal fed back by the atomizer collected by the control circuit 10 through the communication end; in the embodiment, the first connection end m1 connected with the communication end of the battery assembly.

[0135] Further, the driving circuit 20 further comprises a communication signal receiving unit 21 and a communication signal feedback unit 22. The communication signal receiving unit 21 is connected with the communication end to detect the first communication signal uploaded on the communication end of the battery assembly; the communication signal feedback unit 22 is connected with the communication end to generate the second communication signal on the communication end of the battery assembly through the communication end.

[0138] The communication signal feedback unit 22 comprises a third switch 23 connected with the communication terminal, so as to connect the communication terminal of the battery assembly through the communication terminal, and feedback the second communication signal at the communication terminal of the battery assembly through the on / off of the third switch 23. Specifically, the communication signal feedback unit 22 controls the on / off of the third switch 23 according to the result of the digital communication signal transmitted by the first pulse width modulation signal obtained by the data receiving and processing control unit 211 or the result of the digital signal represented by the plurality of spike signals in the first communication signal, so as to feedback the second communication signal at the communication terminal of the battery assembly.

[0139] In the embodiment, if the second communication signal feedback at the communication terminal of the battery assembly is a second spike signal, the third switch 23 is defined as an N-type switch transistor. When the third switch 23 is switched from the off state to the on state, the second spike signal is a lower spike signal; when the third switch 23 is switched from the on state to the off state, the second spike signal is an upper spike signal.

[0140] Further, when the battery assembly and the atomizer establish a communication connection, the battery assembly supplies power to the atomizer through the first communication signal, so that the minimum voltage value of the lower spike signal in the first communication signal is greater than the minimum working voltage of the atomizer, so as to ensure that the atomizer will not be powered off between the battery assembly when working.

[0141] Further, the driving circuit 20 further comprises a signal positive and negative switching unit 24, the signal positive and negative switching unit 24 is connected with the first connecting end m1 and the second connecting end m2, so that the atomizer can be connected with the battery assembly in positive or negative.
