In order to solve the problems, the invention also provides a control circuit of the electronic cigarette.

The power output terminal BAT1 of the power supply circuit 41 is connected to the current output terminal BAT of the ASIC integrated circuit 401, the current input terminal BAT2 of the indicator lamp circuit 45, and the current input terminal of the trigger circuit 44, respectively, the control signal input terminal of the power supply circuit 41 is connected to the control signal output terminal DRT of the ASIC integrated circuit 401, and the detection signal output terminal of the power supply circuit 41 is connected to the first detection signal input terminal CS of the ASIC integrated circuit 401 and the first detection signal output terminal of the heating circuit 46, respectively. The second detection signal output terminal of the heating circuit 46 is connected to the second detection signal input terminal VS of the ASIC integrated circuit 401, and the ground terminal GND of the heating circuit 46 is grounded. The first indication signal output of the indication lamp circuit 45 is connected to the first indication signal input SMOKE of the ASIC integrated circuit 401, and the second indication signal output of the indication lamp circuit 45 is connected to the second indication signal input CHG of the ASIC integrated circuit 401. The control signal output of the trigger circuit 44 is connected to the control signal input KEY of the ASIC integrated circuit 401.
In the above-described embodiment, the overcharge protection circuit 42, the power supply circuit 41, the indicator lamp circuit 45, the heating circuit 46, and the trigger circuit 44 represent the external modules in the first embodiment. After the trigger circuit 44 obtains the control signal, it sends the control signal to the ASIC integrated circuit 401, and controls the operation state of the ASIC integrated circuit 401. When the ASIC integrated circuit 401 is in an operating state, the sampling logic circuit 34 may sample the voltage and the resistance of the power supply circuit 41 and the heating circuit 46, so as to know whether the battery is in the power supply state and the remaining power, and may know the state of the heating circuit 46 through the voltage and the resistance. In addition, the operating state of the indicator lamp circuit 45 changes with the power supply state and the remaining power, and at the same time, the operation of the heating circuit 46 can also be controlled. At this time, since the ASIC integrated circuit 401 is integrated in one chip, the other overcharge protection circuit 42, the power supply circuit 41, the indicator light circuit 45, the heating circuit 46 and the trigger circuit 44 are peripheral connection modules of the chip, compared with the prior art, the area of the PCB occupied by the control circuit of the electronic cigarette is greatly reduced, and meanwhile, the integrated chip reduces various errors caused by circuit assembly in the electronic cigarette production process, greatly improves the production efficiency and reduces the production cost. And because of the existence of the ASIC integrated circuit 401, the application program is preset, so that the post-production is simple, the control program does not need to be developed again with great effort, and the labor is saved.
Optionally, the power supply circuit 41 includes a first MOS transistor Q1 and a battery B1, where an anode of the battery B1 is connected to a drain of the first MOS transistor Q1, a connection node between the drain of the first MOS transistor Q1 and the anode of the battery B1 is connected to a current output end BAT of the ASIC integrated circuit 401, a gate of the first MOS transistor Q1 is connected to a control signal output end of the ASIC integrated circuit 401, and a source of the first MOS transistor Q1 is connected to a first detection signal input end CS of the ASIC integrated circuit 401.
In the above embodiment, the first MOS transistor Q1 is used as a switch, and the first MOS transistor Q1 is an N-type MOS transistor, when the ASIC integrated circuit 401 sends a control signal to make the control signal output terminal DRT of the ASIC integrated circuit 401 and the current output terminal BAT form a forward voltage difference, at this time, the first MOS transistor Q1 is turned on. At this time, the first MOS transistor Q1 may be used for convenient control, so that the operation of the control circuit of the electronic cigarette may more quickly respond to the external control signal, and quick control is realized.
Optionally, the heating circuit 46 includes a first resistor R1 and a second resistor R2, where a first end of the first resistor R1 is connected to a first end of the second resistor R2, a connection node of the first resistor R1 and the second resistor R2 is connected to a first detection signal input terminal CS of the ASIC integrated circuit 401, and a second end of the first resistor R1 is connected to a second detection signal output terminal VS of the ASIC integrated circuit 401; the second end of the second resistor R2 is grounded.
The second resistor R2 is a load heating wire atomizer, and is abstracted into the second resistor R2, since the resistance of the first resistor R1 is fixed, the voltage is divided by the first resistor R1 and the second resistor R2, the ASIC integrated circuit 401 can conveniently measure the voltage difference between two ends of the first resistor R1, so that the resistance of the second resistor R2 can be obtained, the ASIC integrated circuit 401 adjusts the PWM driving duty ratio of the control signal according to the resistance of the second resistor R2, and the first MOS transistor Q1 realizes the limiting function on the maximum power of the second resistor R2 (i.e., the load heating wire atomizer). When the resistance of the second resistor R2 is 0.1Ω -0.15Ω, the first MOS transistor Q1 is adjusted to chopper output by PWM. When the resistance of the second resistor R2 is greater than 0.15Ω, the first MOS transistor Q1 is controlled to output by the same control signal, i.e. pass through. At this time, due to the voltage division effect of the first resistor R1, the ASIC integrated circuit 401 can monitor the working state of the second resistor R2 more intelligently in real time, so that the ASIC integrated circuit 401 can change the output of the control signal in real time according to the resistance value of the second resistor R2 to change the resistance value of the second resistor R2, thereby achieving the purpose of realizing intelligent output of the electronic cigarette.
Optionally, the control circuit of the electronic cigarette further includes an indicator light circuit 45, where the indicator light circuit 45 includes a first light emitting diode D1 and a second light emitting diode D2, an anode of the first light emitting diode D1 is connected to an anode of the second light emitting diode D2, a connection node of the first light emitting diode D1 and the second light emitting diode D2 is connected to the current output terminal BAT of the ASIC integrated circuit 401, and a cathode of the first light emitting diode D1 is connected to the first indication signal input terminal SMOKE of the ASIC integrated circuit 401; the cathode of the second light emitting diode D2 is connected to the second indication signal input CHG of the ASIC integrated circuit 401.
When the current output terminal BAT of the ASIC integrated circuit 401 connected to the first light emitting diode D1 and the second light emitting diode D2 outputs a current normally, the first indication signal input terminal SMOKE of the ASIC integrated circuit 401 controls the operation of the first light emitting diode D1, and the second indication signal input terminal CHG of the ASIC integrated circuit 401 controls the operation of the second light emitting diode D2, at this time:
(1) When the first indication signal input terminal SMOKE of the ASIC integrated circuit 401 is at low level (0V), the first light emitting diode D1 is turned on; when the first indication signal input terminal SMOKE of the ASIC integrated circuit 401 is at a high level (1V), the first light emitting diode D1 is turned off.
(2) When the second indication signal input terminal CHG of the ASIC integrated circuit 401 is at low level (0V), the second light emitting diode D2 is turned on; when the second indication signal input terminal CHG of the ASIC integrated circuit 401 inputs a signal of high level (1V), the second light emitting diode D2 is turned off.
Optionally, a current input of the trigger circuit 44 is connected to a current output of the ASIC integrated circuit 401, and a control signal output of the trigger circuit 44 is connected to a control signal input KEY of the ASIC integrated circuit 401.
When a current flows into the current input terminal of the trigger circuit 44, the control signal output terminal of the trigger circuit 44 is output by a control signal, and the control signal is a trigger level signal. In the above example, the trigger circuit 44 includes the first KEY S, when the first KEY S is closed, there is a current flowing in the circuit to the control signal input KEY of the ASIC integrated circuit 401, when the first KEY S is open, no current flows in the circuit, and if the control signal is a plurality of KEYs, a pulse signal is formed here. When the key is kept for a long time, a continuous analog signal is formed at the moment, and the signal size is not changed. At this time, the key circuit is a window for interaction between the electronic cigarette and the outside, and control signals such as startup, smoking and shutdown are sent out.
Optionally, the control circuit of the electronic cigarette further includes an IC temperature detection circuit, and the IC temperature detection circuits are respectively connected to the third detection signal input NTCASIC of the ASIC integrated circuit 401 and the fourth detection signal input ISET of the integrated circuit 401.
Optionally, the IC temperature detection circuit includes a first thermistor R5 and a second thermistor R3, a first end of the first thermistor R5 is connected to a third detection signal input end of the ASIC integrated circuit, and a second end of the first thermistor R5 is grounded; the first end of the second thermistor R3 is connected with the fourth detection signal input end of the ASIC integrated circuit, and the second end of the second thermistor R3 is grounded.
The IC temperature detecting circuit 43 includes a first thermistor R5 and a second thermistor R3, the third detecting signal input NTC of the ASIC integrated circuit 401 inputs the voltage value of the first thermistor R5 into the ASIC integrated circuit 401, the fourth detecting signal input ISET of the ASIC integrated circuit 401 inputs the voltage value of the second thermistor R3 into the ASIC integrated circuit 401, at this time, the first thermistor R5 is used for detecting the temperature of the integrated chip where the ASIC integrated circuit 401 is located, the second thermistor R3 is used for detecting the battery temperature, and when the temperature exceeds a certain limit value, the ASIC integrated circuit 401 sends a control signal to the power supply circuit 41 and the overcharge protection circuit 42, so that the overcharge protection circuit 42 and the overcharge protection circuit 42 stop working, and the control circuit of the electronic cigarette stops working. It is noted that the second thermistor R3 and the first led D1 form a power supply loop, and the magnitude of the power supply current can be adjusted by adjusting the resistance value of the second thermistor R3.
At this time, due to the detection effect of the first thermistor R5 and the second thermistor R3, the temperature of the integrated chip where the ASIC integrated circuit 401 is located and the temperature of the battery B1 can be comprehensively detected, so that the control circuit of the electronic cigarette works under the condition of good environment, and the service life of the electronic cigarette is prolonged as much as possible.
In addition, as shown in the figure, the overcharge protection circuit 42 is composed of an overshoot protection element and a third resistor R4, where the third resistor R4 can shunt the voltage input/output from the ASIC integrated circuit 401.
At this time, in consideration of the situation that the input current is excessively large, the overcharge protection circuit 42 is provided to shunt the excessively large input current, thereby achieving the purpose of protecting the ASIC integrated circuit 401 and the battery B1.
In order to solve the above technical problems, the present invention further provides a control method of a control circuit of an electronic cigarette based on the control circuit of an electronic cigarette, and referring to fig. 2 to 5, the control method of the control circuit of an electronic cigarette includes:

Optionally, in step S1, specifically, the ASIC integrated circuit 401 obtains a trigger level signal sent by the trigger circuit 44, and then the ASIC integrated circuit 401 compares the trigger level signal with a preset trigger level signal, and outputs a corresponding control signal to the indicator light circuit 45 and the power supply circuit 41 according to the comparison result, so as to control the corresponding indicator light in the indicator light circuit 45 to light according to a preset first lighting mode, and control the power supply state of the battery B1 in the power supply circuit 41. In the above embodiment, the preset first lighting mode and the corresponding actions of the power supply circuit 41 are as follows:
(1) When the number of pulses received by the ASIC integrated circuit 401 in one second is 5, if the ASIC integrated circuit 401 is in an operating state at this time, the ASIC integrated circuit 401 sends out a control signal to cause the second light emitting diode D2 to flash three times continuously, and then the power supply circuit 41 stops supplying power to the ASIC integrated circuit 401.
(2) When the number of pulses received by the ASIC integrated circuit 401 is 5 in one second, if the ASIC integrated circuit 401 is in the standby state at this time, the ASIC integrated circuit 401 sends out a control signal to cause the second light emitting diode D2 to flash three times in succession, and then the power supply circuit 41 starts to supply power to the ASIC integrated circuit 401.
(3) When the pulse width received by the ASIC integrated circuit 401 is greater than 8 seconds, the power supply circuit 41 stops supplying power to the ASIC integrated circuit 401 after the second light emitting diode D2 blinks five times in succession.

Alternatively, step S1 is specifically that the ASIC integrated circuit 401 acquires the resistance value of the heating circuit 46. The ASIC integrated circuit 401 then compares the resistance value of the heating circuit 46 with a preset resistance value, and outputs corresponding control signals to the indicator lamp circuit 45, the heating circuit 46 and the power supply circuit 41 according to the comparison result, so as to control the corresponding indicator lamps in the indicator lamp circuit 45 to light up according to a preset first lighting mode, and control the power supply state of the battery B1 in the power supply circuit 41 and control the resistance value of the first resistor of the heating circuit 46 to change the resistance value according to a preset resistance value changing mode.

(2) When the resistance value of the first thermistor R5 in the heating circuit 46 is not 0.1Ω -3Ω, the second light emitting diode D2 is continuously flashed four times.
(3) When the resistance value of the first thermistor R5 in the heating circuit 46 is greater than 0.15Ω, the first thermistor R5 is dc controlled.

Then, when determining that the control circuit of the electronic cigarette works, the ASIC integrated circuit 401 sends a corresponding control signal to the indicator light circuit 45 and the power supply circuit 41 according to the collected voltage signal of the power supply circuit 41, so as to control the corresponding indicator light in the indicator light circuit 45 to light according to a preset second lighting mode, and control the power supply state of the battery B1 in the power supply circuit 41. Finally, when the power supply circuit 41 supplies power to the control circuit of the whole electronic cigarette, the ASIC integrated circuit 401 sends corresponding control signals to the indicator light circuit 45, the power supply circuit 41 and the heating circuit 46 according to the acquired resistance value of the heating circuit 46, so as to control the corresponding indicator lights in the indicator light circuit 45 to light according to a preset third lighting mode, and adjust the heating circuit 46 and the power supply circuit 41 to work according to the preset mode.
