[0026] Reference Figure 1 and Figure 2 As shown, the control circuit 1 of the power supply assembly provided in the embodiment of the present application includes a main board 10. The main board 10 is provided with at least one port, and the at least one port includes a first end 11, a second end 12 and a third end 13; the at least one port is used to connect to the battery rod 20 or the atomizer 30 through two ends of the first end 11, the second end 12 and the third end 13.

[0027] That is to say, for any port set on the main board 10, two ends of the first end 11, the second end 12 and the third end 13 included in the port can be connected to the battery rod 20 or the atomizer 30. In this way, the control circuit 1 of the power supply assembly provided in the present application achieves compatibility between the atomizer 30 interface and the battery rod 20 interface, and supports forward and reverse insertion of the atomizer 30 and the battery rod 20; when there are multiple ports, any port supports the above-mentioned insertion method, the design is simple, and the operation complexity is reduced.

[0028] In some embodiments of the present application, the first end 11, the second end 12 and the third end 13 included in any port are arranged in sequence and at equal intervals on the same straight line; the distance between the two electrodes of the battery rod 20 is the same as the distance between the first end 11 and the second end 12; the distance between the two electrodes of the atomizer 30 is the same as the distance between the first end 11 and the third end 13.

[0029] For example, in one scenario, taking the case where the main board 10 of the control circuit 1 of the power supply assembly provided by the present application includes two ports, the three ends of one port and the three ends of the other port have an origin-symmetrical structure on the main board 10. In this way, the control circuit 1 of the power supply assembly provided by the present application supports the atomizer 30 and the battery rod 20 to be inserted forward and backward and interchanged on two opposite sides, reducing the complexity of the operation of inserting the atomizer 30 and the battery rod 20 into the control circuit 1 of the power supply assembly.

[0030] For example, in another scenario, the main board 10 of the control circuit 1 of the power supply assembly provided in the present application includes two ports. On the main board 10, the straight line where the three ends of one port are located is perpendicular to the straight line where the three ends of the other port are located. In this way, the control circuit 1 of the power supply assembly provided in the present application supports the atomizer 30 and the battery rod 20 to be inserted forward and backward and interchanged on two adjacent sides, reducing the complexity of the operation of inserting the atomizer 30 and the battery rod 20 into the control circuit 1 of the power supply assembly.

[0031] For example, in a feasible scenario, referring to Figure 1 As shown, a port of the main board 10 is connected to the battery rod 20 via the first end 11 and the second end 12; alternatively, a port of the main board 10 is connected to the battery rod 20 via the second end 12 and the third end 13. It should be noted that the battery rod 20 has positive and negative electrodes. Figure 1 FIG. 2 exemplarily shows that the positive electrode 21 of the battery rod 20 is connected to the first end 11 of the main board 10, and the negative electrode 22 of the battery rod 20 is connected to the second end 12 of the main board 10, so that the current flows out from the positive electrode 21 of the battery rod 20, flows into the main board 10 through the first end 11 of the main board 10, and then flows back from the negative electrode 22 of the battery rod 20 through the second end 12 of the main board 10. Assume Figure 1The insertion mode in which one port of the main board 10 is connected to the battery rod 20 is called positive insertion. Then, the positive pole 21 of the battery rod 20 is connected to the third end 13 of the main board 10, and the negative pole 22 of the battery rod 20 is connected to the second end 12 of the main board 10, so that the current flows out from the positive pole 21 of the battery rod 20, flows into the main board 10 through the third end 13 of the main board 10, and then flows back from the negative pole 22 of the battery rod 20 through the second end 12 of the main board 10. The insertion mode in which one port of the main board 10 is connected to the battery rod 20 is called reverse insertion. In this way, the control circuit 1 of the power supply assembly provided in the present application supports the battery rod 20 to be inserted forward and reversely at any port, reducing the complexity of the operation of connecting the battery rod 20.

[0032] For example, in another possible scenario, referring to Figure 2 As shown, a port of the main board 10 is connected to the atomizer 30 via the first end 11 and the third end 13; or, a port of the main board 10 is connected to the atomizer 30 via the third end 13 and the first end 11. It should be noted that the atomizer 30 does not have positive and negative electrodes. Figure 2 exemplarily shows a connection method between the atomizer 30 and the main board 10, which is used to make the current flow into the one end 31 of the atomizer 30 through the first end 11 of the main board 10, and then flow back from the other end 32 of the atomizer 30 through the third end 13 of the main board 10. Assume Figure 2 The insertion mode in which one port of the main board 10 is connected to the atomizer 30 is called forward insertion. Then, the other end 31 of the atomizer 30 is connected to the third end 13 of the main board 10, and the one end 32 of the atomizer 30 is connected to the first end 11 of the main board 10, so that the current flows into the other end 32 of the atomizer 30 through the first end 11 of the main board 10, and then flows back from the one end 31 of the atomizer 30 through the third end 13 of the main board 10. The insertion mode in which one port of the main board 10 is connected to the atomizer 30 is called reverse insertion. In this way, the control circuit 1 of the power supply assembly provided in the present application supports forward and reverse insertion of the atomizer 30 at any port, reducing the complexity of the operation of connecting the atomizer 30.

[0033] As can be seen from the above content, the control circuit 1 of the power supply assembly provided in the embodiment of the present application includes a main board 10, and the main board 10 is provided with at least one port, and the at least one port includes a first end 11, a second end 12 and a third end 13; the at least one port is used to connect with the battery rod 20 or the atomizer 30 through two ends of the first end 11, the second end 12 and the third end 13. The atomizer 30 and the battery rod 20 must be inserted in a specific way in the related art. The control circuit 1 of the power supply assembly provided in the present application has an atomizer 30 interface that is compatible with the battery rod 20 interface, and supports the forward and reverse insertion of the atomizer 30 and the battery rod 20; when there are multiple ports, any port supports the above insertion method, the design is simple, and the operation complexity is reduced.

[0034] In some embodiments of the present application, the atomizer 30 is a device that atomizes an aerosol atomization matrix into an aerosol. The atomizer 30 can be applied to various atomization scenarios. For example, the atomizer 30 can be applied to atomization scenarios such as medical cosmetology, nicotine delivery, and daily life. The aerosol atomization matrix can be a powder, a fragrance, a nicotine preparation, and an aerosol matrix that can produce a special smell. It can be understood by those skilled in the art that there can be many application scenarios for the atomizer 30, and the embodiments of the present application do not limit the application scenarios of the atomizer.

[0035] Exemplarily, the atomizer 30 may include an atomizer core, an atomizer nozzle, and an atomizer 30 plug-in port. The atomizer core includes a heating element, which is used to heat and atomize the oil in the atomizer 30 to generate smoke. The atomizer nozzle is provided with an air outlet channel, through which the atomizer core and the atomizer nozzle are connected, and smoke is drawn out of the atomizer nozzle through the air outlet channel.

With the cooperation of at least some of the multiple modules, the functions of battery rod charging and atomizer suction are supported.

[0042] In some embodiments of the present application, refer to Figure 3 As shown, the control chip 15 is used to control the conduction or disconnection between the first end 11 and the charging chip 14 through the first switch circuit 16 .

[0043] Exemplarily, when the control end of the first switch circuit 16 detects a control signal sent by the control chip 15 , the first switch circuit 16 responds to the control signal to control the conduction or disconnection between the first end 11 and the charging chip 14 .

[0051] Exemplarily, the control signal may include a high-level signal and a low-level signal. When the control chip 15 sends a high-level signal to at least some of the multiple switch circuits mentioned above through the control terminal, the transistors in at least some of the switch circuits mentioned above may be controlled to be reverse cutoff, thereby controlling the switch circuit corresponding to the transistor to be disconnected to achieve the corresponding function.

[0052] In some embodiments of the present application, refer to Figure 3 and Figure 4 As shown, the main board 10 further includes: a battery protection chip 101 , the other end of the second switch circuit 17 is connected to the second end 12 via the battery protection chip 101 ; the other end of the third switch circuit 18 is connected to the second end 12 via the battery protection chip 101 .

[0053] In some embodiments of the present application, refer to Figure 3 and Figure 4 As shown, the battery protection chip 101 is used to control the conduction or disconnection between the second switch circuit 17 and the second end 12 ; the battery protection chip 101 is used to control the conduction or disconnection between the third switch circuit 18 and the second end 12 .

[0054] Exemplarily, in one scenario, when the battery protection chip detects that the current flowing through itself exceeds a preset current threshold, it controls the second switch circuit 17 to be disconnected from the second end 12 to protect the battery cells of the battery rod and prevent the battery cells of the battery rod connected to the main board 10 from being damaged due to excessive current.

[0055] Exemplarily, the battery protection chip 101 may be a lithium protection chip for protecting circuits and circuit elements.

[0056] In some embodiments of the present application, refer to Figure 4As shown, the first switch circuit 16 includes: a first resistor R1, a second resistor R2 and a first transistor Q1. The drain of the first transistor Q1 is connected to the first terminal 11, the source of the first transistor Q1 is connected to the other terminal of the charging chip 14, the gate of the first transistor Q1 is connected to the other terminal of the charging chip 14 through the first resistor R1, and the gate of the first transistor Q1 is connected to the control terminal of the first switch circuit 16 through the second resistor R2.

[0057] The second switch circuit 17 includes a third resistor R3 and a second transistor Q2. The drain of the second transistor Q2 is connected to the first terminal 11, the source of the second transistor Q2 is connected to the ground, and the gate of the second transistor Q2 is connected to the control terminal of the second switch circuit 17 through the third resistor R3.

[0058] The third switch circuit 18 includes: a fourth resistor R4 and a third transistor Q3, the drain of the third transistor Q3 is connected to the third terminal 13, the source of the third transistor Q3 is connected to the ground, the source of the third transistor Q3 is connected to the source of the second transistor Q2, and the gate of the third transistor Q3 is connected to the control terminal of the third switch circuit 18 through the fourth resistor R4.

[0059] The fourth switch circuit 19 includes: a fifth resistor R5, a sixth resistor R6 and a fourth transistor Q4, the drain of the fourth transistor Q4 is connected to the third end 13, the source of the fourth transistor Q4 is connected to the other end of the charging chip 14, the gate of the fourth transistor Q4 is connected to the control end of the fourth switch circuit 19 through the fifth resistor R5, and the gate of the fourth transistor Q4 is connected to the other end of the charging chip 14 through the sixth resistor R6.

[0060] The first switch circuit 16 provided in the embodiment of the present application includes the following multiple components: a first resistor R1, a second resistor R2 and a first transistor Q1; the second switch circuit 17 includes the following multiple components: a third resistor R3 and a second transistor Q2; the third switch circuit 18 includes the following multiple components: a fourth resistor R4 and a third transistor Q3; the fourth switch circuit 19 includes the following multiple components: a fifth resistor R5, a sixth resistor R6 and a fourth transistor Q4. With the mutual cooperation of at least some of the above-mentioned multiple components, the above-mentioned multiple switch circuits are supported to be turned on or off to achieve corresponding functions, and through the ingenious design of the above-mentioned MOS tube, the circulation problem of multi-cell charging is solved at a low cost.

[0061] In the embodiment of the present application, when the first transistor Q1 is a P-channel insulated gate field effect transistor (PMOS), after the control chip 15 provides a pull-down voltage to the gate of the first transistor Q1 via the control terminal, the body diode of the first transistor is forward-conducted, thereby controlling the first switch circuit 16 to be turned on.

[0062] When the second transistor Q2 is an N-channel insulated gate field effect transistor (NMOS), after the control chip 15 provides a pull-down voltage to the gate of the second transistor Q2 via the control terminal, the body diode of the first transistor is reversely cut off, thereby controlling the second switch circuit 17 to be disconnected.

[0063] When the third transistor Q3 is an N-channel insulated gate field effect transistor (NMOS), after the control chip 15 provides a pull-down voltage to the gate of the third transistor Q3 via the control terminal, the body diode of the third transistor is reversely cut off, thereby controlling the third switch circuit 18 to be disconnected.

[0064] When the fourth transistor Q4 is a P-channel insulated gate field effect transistor (PMOS), after the control chip 15 provides a pull-down voltage to the gate of the fourth transistor Q4 via the control terminal, the body diode of the fourth transistor is forward-conducted, thereby controlling the fourth switch circuit 19 to be turned on.

[0065] For example, when two battery rods are inserted into both sides of the main board 10, a parallel path is formed between the two battery rods. However, due to the inconsistency of the internal resistance and voltage of the battery cells of the two battery rods, circulating heat will be generated, causing damage to the battery rods. Therefore, a first resistor R1 is provided to provide a pull-up voltage to the first transistor Q1 to enable the first transistor Q1 to achieve high-position self-locking after the battery rod 20 is inserted into the main board 10, so that the body diode of the first transistor Q1 is reversely cut off, thereby controlling the first switch circuit 16 to be disconnected. In this way, when the battery rod 20 is inserted into the main board 10, the pull-up voltage provided by the first resistor R1 can be used to put the first switch circuit 16 in an off state, actively avoiding the problem of circulating heat generated by the inconsistency of the internal resistance and voltage of the battery cells of the two battery rods when the two battery rods are inserted into both sides of the main board 10.

[0066] Exemplarily, when two battery rods are inserted into both sides of the main board 10, a parallel path is formed between the two battery rods. However, due to the inconsistency of the internal resistance and voltage of the battery cells of the two battery rods, circulating heat will be generated, causing damage to the battery rods. Therefore, a sixth resistor R6 is provided to provide a pull-up voltage to the fourth transistor Q4 to enable the fourth transistor Q4 to achieve high-position self-locking after the battery rod 20 is inserted into the main board 10, so that the body diode of the fourth transistor Q4 is reversely cut off, thereby controlling the fourth switch circuit 19 to be disconnected. In this way, when the battery rod 20 is inserted into the main board 10, the fourth switch circuit 19 can be in a disconnected state through the pull-up voltage provided by the sixth resistor R6, actively avoiding the problem of circulating heat generated by the inconsistency of the internal resistance and voltage of the battery cells of the two battery rods when the two battery rods are inserted into both sides of the main board 10.

[0067] In the embodiment of the present application, when the first transistor Q1 is PMOS and the second transistor Q2 is NMOS, the control chip provides a pull-down voltage to the gate of the first transistor Q1 to turn on the forward direction of the first transistor Q1, and provides a pull-down voltage to the gate of the second transistor Q2 to turn off the reverse direction of the second transistor Q2, thereby controlling the conduction between the first terminal 11 and the charging chip 14 through the first switch circuit 16 corresponding to the first transistor Q1, and controlling the disconnection between the first terminal 11 and the ground through the second switch circuit 17 corresponding to the second transistor Q2. In this way, when a battery rod is inserted into one side of the main board, the first switch can be controlled to be turned on to achieve good conduction performance, while the second switch can be controlled to be disconnected to avoid the risk of the positive electrode of the battery rod being short-circuited to the ground, so that the conduction performance of the first switch is more stable, and good and stable conduction performance of the battery rod is achieved. By setting the above-mentioned PMOS-NMOS group, it is possible to provide the same control signal to the control ends corresponding to the PWM_P1 network and the PWM_N2 network at the same time, that is, to provide a pull-up voltage to the control ends of the first switch circuit and the second switch circuit at the same time to control the first switch circuit to be turned on and the second switch circuit to be turned off, thereby realizing the combined control of the switch circuits corresponding to the above-mentioned PMOS-NMOS group, saving the pin resources of the control chip 15 and simplifying the software operation.

[0068] Exemplarily, the first transistor, the second transistor, the third transistor, and the fourth transistor may also be selected from any of a P-channel insulated gate field effect transistor (PMOS) and an N-channel insulated gate field effect transistor (NMOS) to achieve a unified setting, and the embodiment of the present application does not specifically limit this, and the channel type of the insulated gate field effect transistor can be reasonably set according to actual needs. It should be noted that when the transistor type is replaced, the pull-up and pull-down strategies of the corresponding control network need to be changed accordingly to achieve the functions implemented by the above-mentioned control circuit of the present application.

[0069] The present application provides a control method for a power supply assembly, referring to Figure 5 As shown, the method comprises the following steps:

[0070] Step 501: Determine, based on the type of the electrical signal of the first end 11, whether at least one port corresponding to the first end 11 is connected to the battery rod 20 or the atomizer 30 .

[0071] Among them, the electrical signal type can be a voltage signal or a current signal, which can be set according to actual needs and is not limited in this application.

[0072] In some embodiments of the present application, step 501 can be implemented by the following steps:

[0073] If it is detected that the first end 11 has a first electrical signal, it is determined that at least one port corresponding to the first end 11 having the first electrical signal is connected to the battery rod 20 .

[0074] In actual application, after the battery rod 20 is inserted, the positive electrode 21 of the battery rod 20 is connected to the first end 11 (B+ / HL+), and the negative electrode 22 of the battery rod 20 is connected to the second end 11 (BL-). The current in the battery rod is conducted to the V_Bat network through the body diode of the first transistor Q1, and the main board 10 is powered on. Due to the voltage drop across the two ends of the battery rod 20, when a first electrical signal is detected on at least one port corresponding to the first end 11 of the main board 10, it indicates that a battery rod 20 is inserted into the port.

[0075] If it is detected that the first end 11 has a second electrical signal, it is determined that at least one port corresponding to the first end 11 having the second electrical signal is connected to the atomizer.

[0076] In practical applications, after the atomizer is inserted, one end 31 of the atomizer is connected to the fourth end 112 (B+ / HR+), and the other end 32 of the atomizer is connected to the sixth end 132 (B+ / HR-), and connected to the V_Bat network through the body diode of the fifth transistor Q5. Since there is no voltage at both ends of the atomizer, when a second electrical signal is detected on at least one port corresponding to the first end 11 of the main board 10, it indicates that the port has an atomizer inserted. The second electrical signal is smaller than the first electrical signal.

[0077] In some embodiments of the present application, at least one port includes two ports. If the first end 11 is detected to have a first electrical signal, after determining that at least one port corresponding to the first end 11 having the first electrical signal is connected to the battery rod 20, refer to Figure 4 and Figure 6 As shown, the control method for charging under two battery charging states can be implemented by the following steps:

[0078] If it is detected that the first ends 11 of the two ports have the first electrical signal, it is determined that the two ports are respectively connected to the battery rod 20 .

[0079] If it is detected that the output voltage of the other end of the charging chip 14 is greater than the voltage threshold, a first signal is output to the control end of the first switch circuit 16 corresponding to the two ports respectively, so as to control the conduction between the first end 11 and the charging chip 14 through the first switch circuit 16.

[0080] The first signal is a low level signal, and is used to pull down the control network corresponding to the control terminal when the control chip 15 outputs a low level signal to the control terminal. The first signal can also be called a first control signal, and is used to implement pull-down control.

[0081] When it is detected that the first ends 11 of the two ports have the first electrical signal, it indicates that the battery rods 20 are inserted into the first ends 11 of the two ports, and the main board 10 enters the dual-battery charging standby state.

[0082] Taking the case where a battery cell is inserted into the upper left end and a battery cell is inserted into the upper right end as an example, in actual application, when it is detected that the output voltage of the other end of the charging chip 14 is greater than the voltage threshold, it indicates that an external power source is inserted into the mainboard 10. The charging chip 14 controls the external power source and provides a higher voltage to the V_Bat network, so that the mainboard 10 enters a dual battery charging state. Then, the control chip 15 simultaneously outputs a low level to the control end of the first switch circuit 16 corresponding to each of the two ports, and simultaneously pulls down the control network (PWM_P1) corresponding to the control end of the first switch circuit 16 corresponding to each of the two ports, and controls the first switch circuit 16 corresponding to each of the two battery rods to be turned on. At this time, the higher voltage current provided by the external power supply can flow into the positive electrode 21 of the battery rod 20 through the V_Bat network on the mainboard 10 through the first end 11 port corresponding to each of the battery rods 20, and flow back to the V_Bat network from the negative electrode 22 of the battery rod 20 through the second end 12 port corresponding to each of the battery rods, forming a dual battery charging circuit. Then, the control chip 15 controls the charging chip 14 to start charging the two battery rods simultaneously. In this way, multiple batteries can be charged simultaneously, which saves charging time and improves charging efficiency.

[0083] In some embodiments of the present application, after determining that the two ports are respectively connected to the battery rod 20 , the following steps are included: controlling the first ends 11 of the two ports to be disconnected from the charging chip 14 by the first switch circuit 16 .

[0084] Taking the case where the battery cell is inserted at the upper end of the left side and the battery cell is inserted at the upper end of the right side as an example, in actual application, after the battery rod 20 is inserted at the left side, the positive electrode 21 of the battery rod 20 is connected to the V_Bat network through the first end 11 (B+ / HL+) and the body diode of the first transistor Q1, and the main board 10 is powered on. At this time, due to the presence of the first resistor, when the battery rod 20 at the left side is inserted, the high position self-locking of the first transistor is realized through the pull-up potential provided by the first resistor, and the first switch will not be turned on, actively avoiding the circulation problem caused by the inconsistent battery cell internal resistance and voltage of the two battery rods. Then the battery rod 20 at the right side is inserted. Similarly, due to the presence of the second resistor, the body diodes of the first transistor Q1 and the fifth transistor Q5 are in the disconnected state at this time, and the corresponding body diodes play a role in preventing the circulation, avoiding the circulation heating problem caused by the inconsistent battery cell internal resistance and voltage when the two battery rods are inserted into the main board at the same time.

[0085] In some embodiments of the present application, at least one port includes two ports. If the first end 11 is detected to have a second electrical signal, after determining that at least one port corresponding to the first end 11 having the second electrical signal is connected to the atomizer, refer to Figure 4 and Figure 7 As shown, the control method for powering on in the pumpable state can be implemented by the following steps:

[0086] If it is detected that the first end 11 of one of the two ports has a first electrical signal, it is determined that the port having the first electrical signal is connected to the battery rod 20 .

[0087] If it is detected that the first end 11 of the other port of the two ports has a second electrical signal, it is determined that the port having the second electrical signal is connected to the atomizer 30 .

[0088] The first switch circuit 16 corresponding to the port having the second electrical signal controls the corresponding first end 11 to be disconnected from the atomizer 30 .

[0089] The fourth switch circuit 19 corresponding to the port having the second electrical signal controls the corresponding third terminal 13 to be disconnected from the atomizer 30 .

[0090] When a first electrical signal is detected at the first end 11 of one of the two ports, it indicates that a battery rod 20 is inserted into the first end 11 of the one port. When a second electrical signal is detected at the first end 11 of the other of the two ports, it indicates that an atomizer 30 is inserted into the first end 11 of the other port, and the main board 10 enters the suction standby state.

[0091] Taking the case where the battery core is inserted into the upper end of the left side and the atomizer core is inserted into the right side as an example, when the main board 10 enters the suction standby state and before entering the suction state, in actual application, when the fourth end 112 port (B+ / HR+) and the sixth end 132 port (B+ / HR-) on the right side are inserted into the two poles of the atomizer 30, and the first end 11 port (B+ / HL+) and the second end 12 port (BL-) on the left side are inserted into the positive and negative poles of the battery rod 20, the positive pole 21 of the battery rod 20 is connected to the V_Bat network through the first end 11 (B+ / HL+) and the body diode of the first transistor Q1, and the main board 10 is powered on. At this time, due to the presence of the first resistor, when the left battery rod 20 is inserted, the high position self-locking of the first transistor is realized through the pull-up potential provided by the first resistor, and the corresponding switch circuit will not be turned on. At this time, no current flows through the atomizer 30 inserted into the main board 10, and it is in a puffing standby state. Thus, by setting a pull-up resistor in the circuit, it is ensured that the atomizer 30 does not heat itself in the non-puffing stage, thereby achieving controllable heating of the atomizer.

[0092] In some embodiments of the present application, when the main board 10 enters the suction state, after determining that the port with the first electrical signal is connected to the battery rod 20, the following steps are included:

[0093] The first signal is output to the control end of the first switch circuit 16 corresponding to the port with the first electrical signal, so as to control the conduction between the first end 11 and the charging chip 14 through the first switch circuit 16 .

[0094] The first signal is output to the control end of the second switch circuit 17 corresponding to the port with the first electrical signal, so as to control the first end 11 and the charging chip 14 to be disconnected through the second switch circuit 17 .

[0095] After the host is powered on, the control chip 15 outputs a low level to the control end of the first switch circuit 16 corresponding to the port with the first electrical signal, pulls down the control network (PWM_P1) corresponding to the control end of the first switch circuit 16, and controls the first switch to be turned on; the control chip 15 outputs a low level to the control end of the second switch circuit 17 corresponding to the port of the first electrical signal, pulls down the control network (PWM_N1) corresponding to the control end of the first switch circuit 16, and controls the second switch to be turned off. In this way, while controlling the first switch to be turned on to achieve good conduction performance, the second switch is controlled to be turned off to avoid the risk of the positive electrode of the battery rod being short-circuited to the ground, making the conduction performance of the first switch more stable, and achieving good and stable conduction performance of the battery rod.

[0096] Furthermore, when the main board 10 enters the suction state, after determining that the port with the second electrical signal is connected to the atomizer 30, the following steps are included:

[0097] Outputting a first signal to a control end of the first switch circuit 16 corresponding to the port having the second electrical signal, so as to control conduction between the first end 11 and the charging chip 14 through the first switch circuit 16;

[0098] Outputting a first signal to a control end of a second switch circuit 17 corresponding to the port having the second electrical signal, so as to control the first end 11 to be disconnected from the ground through the second switch circuit 17;

[0099] Outputting a second signal to the control end of the third switch circuit 18 corresponding to the port having the second electrical signal, so as to control the conduction between the third end 13 and the ground through the third switch circuit 18;

[0100] The second signal is output to the control end of the fourth switch circuit 19 corresponding to the port with the second electrical signal, so as to control the fourth end 112 to be disconnected from the charging chip 14 through the fourth switch circuit 19 .

[0101] The first signal is a low level signal, and is used to pull down the control network corresponding to the control terminal when the control chip 15 outputs a low level signal to the control terminal. The first signal can also be called a first control signal, and is used to implement pull-down control.

[0102] The second signal is a high level signal, and is used to pull up the control network corresponding to the control terminal when the control chip 15 outputs a high level signal to the control terminal. The second signal can also be called a second control signal, and is used to implement pull-up control.

[0103] When the control chip 15 detects the suction signal from the atomizing nozzle, the control main board 10 enters the suction state. The control chip 15 outputs a low level to the control end of the fifth switch circuit corresponding to the port with the second electrical signal, pulls down the control network (PWM_P2) corresponding to the control end of the fifth switch circuit, and controls the fifth switch to be turned on; the control chip 15 outputs a low level to the control end of the sixth switch circuit corresponding to the port with the second electrical signal, pulls down the control network (PWM_N1) corresponding to the control end of the sixth switch circuit, and controls the sixth switch to be turned off; outputs a high level to the control end of the seventh switch circuit corresponding to the port with the second electrical signal, pulls up the control network (PWM_N4) corresponding to the control end of the seventh switch circuit, and controls the seventh switch to be turned off; outputs a high level to the control end of the eighth switch circuit corresponding to the port with the second electrical signal, pulls up the control network (PWM_P3) corresponding to the control end of the eighth switch circuit, and controls the eighth switch to be turned off. At this time, the current in the battery rod 20 inserted on the left side flows into the V_Bat network of the main board 10 through the first end 11 port, and flows into one end 31 of the atomizer 30 from the fourth end 112 port, and flows back to the V_Bat network from the other end 32 of the atomizer 30 through the sixth end 132 of the main board 10, forming the atomizer 30 suction circuit. Then, the control chip 15 controls the switch circuit to start supplying power to the atomizer 30. In this way, the heating element of the atomizer 30 realizes load heating and can realize the suction function; in addition, the atomizer 30 has no positive and negative poles, and the atomizer 30 can be reversely powered, with a two-way heating function.
