Fig. 1 is a block diagram of a circuit for preventing a microphone from being triggered by mistake according to an embodiment of the present invention.
Referring to fig. 1, the circuit for preventing microphone false triggering includes a conductive component (not shown), a USB interface 10, a pull-up resistor R1, and a controller 20; wherein, the function pin OTG of the USB interface 10 is connected to the controlled end of the controller 20 (i.e. one I/O pin of the controller 20); the grounding pin of the USB interface 10 is grounded; one end of the pull-up resistor R1 is connected with a power supply end VDD of the controller 20, and the other end of the pull-up resistor R1 is connected with a controlled end of the controller 20; the conductive component and the USB interface 10 are separately disposed, that is, the conductive component and the USB interface 10 exist independently.
The conductive component can be composed of conductive metal or a conductive silica gel plug. The conductive component is adapted to the USB interface 10 and is pluggable into the USB interface 10.
The USB interface 10 is disposed on the body of the electronic cigarette.
The controller 20 may be a single chip, a DSP or a microprocessor such as an FPGA.
The working principle of the circuit is as follows:
when the conductive component is not plugged into the USB interface 10, the level of the controlled terminal of the controller 20 is pulled high through the pull-up resistor R1, so that the controlled terminal of the controller 20 is at a high level. In this case, the electronic cigarette is in the on state, and once the user has the action of smoking, the microphone can transmit the smoking signal to the controller 20, and the controller 20 drives the atomizer to atomize the tobacco tar for the user to use.
When the conductive component is inserted into the USB interface 10, the functional pin OTG of the USB interface 10 is shorted with the ground GND due to the insertion of the conductive component, and then the controlled terminal of the controller 20 is also shorted with the ground GND, and the equivalent circuit structure is as shown in fig. 2. At this time, the controlled terminal of the controller 20 is turned from high level to low level, in which case the electronic cigarette is turned off. When the electronic cigarette is in a power-off state, the microphone cannot trigger the circuit to work no matter whether the user has smoking action or not. That is, once the controlled end of the controller 20 is low, the controller 20 will not drive the atomizer to atomize the liquid smoke for the user to use regardless of whether the microphone has a smoking signal transmitted to the controller 20 or not until the controlled end of the controller 20 is reset high, so as to prevent the microphone from being triggered by mistake.
According to the technical scheme, when the conductive component is not inserted into the USB interface 10, the controlled end of the controller 20 is at a high level, the electronic cigarette is in a starting state, and the microphone of the electronic cigarette can trigger the atomizer to atomize the oil smoke for a user to use; when the conductive component is inserted into the USB interface 10, the controlled end of the controller 20 is turned from the high level to the low level, the electronic cigarette is in a shutdown state, and the microphone of the electronic cigarette cannot trigger the atomizer to atomize the oil smoke for the user to use. So set up, can prevent that the miaow head from being triggered by the mistake, the effectual security and the reliability that have improved the electron cigarette.

the microphone 30 is connected to an input terminal of the controller 20, an output terminal of the controller 20 is connected to an input terminal of the driving circuit 40, and an output terminal of the driving circuit 40 is connected to the atomizer 50.
The specific working principle is as follows:
when the conductive component is not plugged into the USB interface 10, the level of the controlled terminal of the controller 20 is pulled high through the pull-up resistor R1, so that the controlled terminal of the controller 20 is at a high level. Under this condition, the electron cigarette is the on state, and in case the user has the smoking action, the miaow head can transmit smoking signal to controller 20, and controller 20 control drive circuit 40 output voltage to atomizer 50 for atomizer 50 can atomize the tobacco tar and supply the user to use.
When the conductive component is inserted into the USB interface 10, the functional pin of the USB interface 10 is shorted to the ground GND due to the insertion of the conductive component. At this time, the controlled terminal of the controller 20 is directly grounded, and the controlled terminal of the controller 20 is inverted from high level to low level. In this case, the electronic cigarette is in a power-off state, and the microphone 30 cannot trigger the circuit to operate regardless of whether the user has a smoking action.
Optionally, referring to fig. 4, in an embodiment, the circuit for preventing microphone false triggering further includes a charging management circuit 60 and a rechargeable battery 70; the USB interface 10 is electrically connected to the charging management circuit 60, and the charging management circuit 60 is electrically connected to the rechargeable battery 70.
