The present disclosure discloses an electronic cigarette, a battery thereof is connected to an atomizing device through a first power supply circuit, the battery is connected to a first detecting device through a second power supply circuit, and first information detected by the first detecting device is used to indicate whether the electronic cigarette is in a suction state. The electronic cigarette further comprises a switching key, an on-off key, a second detecting device and an MCU, the on-off key is configured for controlling the first power supply circuit to be ON and OFF, and the second information detected by the second detecting device is used to indicate the position of the switching key; the MCU controls the second power supply circuit to be ON and OFF according to the second information.

Electronic cigarette

The disclosure provides a voltage output circuit. The voltage output circuit includes a control chip and a buck switch chip. The control chip includes a first control signal input terminal, a second control signal input terminal, and a modulation signal output terminal. The buck switch chip includes a first channel terminal, a first control terminal, and a second channel terminal. The first channel terminal receives a system power supply voltage. The first control terminal is connected to the modulation signal output terminal of the control chip. When the first control signal input terminal and/or the second control signal input terminal receives an effective level, the control chip controls the second channel terminal to output a driving voltage.

Voltage output circuit and electronic cigarette

A voltage output circuit and an electronic cigarette are provided. The voltage output circuit includes a control chip and a step-down switch chip. When a first switch element turns on, the modulation signal output terminal of the control chip outputs a pulse modulation signal to a first control terminal of the step-down switch chip, and access between a first access terminal and a second access terminal of the step-down switch chip is established, based on the effective pulse modulation signal. The output voltage of the second access terminal is less than a system power voltage. The voltage output circuit and the electronic cigarette outputs the pulse modulation signal to the step-down switch chip by the control chip, and the step-down switch chip outputs a suitable driving voltage to the load, such as a thermal wire, the voltage output circuit with simplified structure is adjustable and improved.

Voltage output circuit for electronic cigarette and electronic cigarette using circuit

A control method and apparatus for an electronic cigarette are disclosed. The method includes: after a terminal establishes a wireless connection with an electronic cigarette bound with the terminal, the terminal detecting whether the terminal or the electronic cigarette enters a non-smoking area; when the terminal detects that the terminal or the electronic cigarette enters a non-smoking area, the terminal sending a smoking banning signal to the electronic cigarette; wherein the smoking banning signal is used to instruct the electronic cigarette, after receiving the smoking banning signal, to stop atomizing in response to the smoking triggering signal, thereby solving the problem that some users use the electronic cigarette in public places to reduce the air quality, and achieving the effect of improving the air quality in public places.
