The present invention will be further described with reference to the following examples for facilitating understanding of those skilled in the art, and the description of the embodiments is not intended to limit the present invention.

The utility model provides an electronic cigarette circuit as shown in fig. 1, which comprises an airflow pressure detection unit C1, an amplifier U3, a control circuit 1, a heating unit and a power supply unit;

Preferably, the airflow pressure detecting unit C1 is a gas pressure sensor, and is configured to measure a gas pressure, and if the gas pressure sensor detects that the airflow inside the electronic cigarette changes due to the electronic cigarette being smoked by the user, the airflow pressure sensor generates a signal and transmits the signal to the control circuit 1, so as to control the electronic cigarette circuit to start and stop.

The working principle of the circuit is as follows: adopt ternary electricity core BAT to supply power for the electron cigarette circuit, when airflow pressure detecting element C1 detects that the gas pressure change in the electron cigarette reaches and predetermines the change threshold value, airflow pressure detecting element C1 produces the signal and transmits to amplifier U3, amplifier U3 amplifies above-mentioned signal, when the signal amplifies to predetermineeing the amplification threshold value, amplifier U3 will satisfy the signal transmission who predetermineeing the amplification threshold value and handle to control circuit 1, control circuit 1 control heating element starts to generate heat, in order to heat the atomizer of electron cigarette, if airflow pressure detecting element C1 detects that the gas pressure in the electron cigarette does not reach and predetermine the change threshold value, the electron cigarette circuit stops working, in order to reduce cost like this, promote the security of circuit operation.

In this embodiment, the control circuit 1 includes a control unit U4 and a MOS transistor Q1;

the SW end and the VDD end of the control unit U4 are respectively and electrically connected with the port 4 of the amplifier U3 and the ternary battery cell BAT, and the SW end of the control unit U4 is the input end of the control circuit 1;

When the SW terminal of the control unit U4 receives a signal that satisfies a preset amplification threshold, the control unit U4 starts the VDD terminal to output a voltage to the D terminal of the MOS transistor Q1 (the value of the voltage output is equal to the output voltage of the ternary battery cell BAT), and the AT terminal of the control unit U4 outputs a PWM switching signal to the G terminal of the MOS transistor Q1, and the MOS transistor Q1 processes the PWM switching signal and outputs a constant voltage from the S terminal (the constant voltage is the output voltage of the ternary battery cell BAT), thereby driving the heating unit to generate heat.

In this embodiment, the output voltage of the S terminal of the MOS transistor Q1 is 3 to 3.3V. Preferably, the output voltage of the S terminal of the MOS transistor Q1 is 3.2V, so as to be consistent with the output voltage of the ternary battery cell BAT, thereby ensuring that the S terminal of the MOS transistor Q1 outputs a constant voltage, and further ensuring the heating effect of the heating unit on the electronic cigarette atomizer.

The light-emitting unit D1 is a working lamp, that is, when the electronic cigarette circuit is running, that is, when the control unit U4 receives a signal meeting a preset amplification threshold, the light-emitting unit D1 is turned on to indicate that the electronic cigarette circuit is running, and when the electronic cigarette circuit stops running, the light-emitting unit D1 is turned off; of course, the lighting unit D1 may be turned off when the electronic cigarette circuit is running, or turned on when the electronic cigarette circuit is stopped, or the lighting unit D1 may be normally on, but the lighting color of the lighting unit D1 is different when the electronic cigarette circuit is running and turned off.

In this embodiment, the light emitting unit D1 is an LED lamp. The LED lamp has the characteristics of low energy consumption and long service life, so that the energy consumption of the ternary battery cell BAT is reduced, and the service life of the electronic cigarette is prolonged.

Further, the resistance of the resistor R1 can be reduced to reduce the load of the electronic cigarette circuit, so that the service life of the ternary battery cell BAT is prolonged, and the heating of the atomizer can be realized only by satisfying the resistance of the resistor R1 of the electronic cigarette circuit in a working state.

The electronic cigarette adopts the electronic cigarette circuit, so that the cost is effectively reduced, the service life of the electronic cigarette is prolonged, and the use safety of the electronic cigarette is also ensured.
