  • Publication number: 20200237007
    Abstract: A voltage output circuit, an electronic device and an electronic cigarette are provided. The voltage output circuit includes a battery assembly and a control circuit. The battery assembly is electrically connected with an atomizing circuit. A first signal output end of the control circuit is connected with a main control circuit, and a second signal output end of the control circuit is connected with the main control circuit. When the main control circuit receives a sensing signal output by the first signal output end and a load working signal output by the second signal output end, the main control circuit controls the battery assembly to supply power to the atomizing circuit, such that the atomizing circuit starts to work, thereby solving the problem that the mechanical key is easy to be triggered by non-human in the related art to cause potential safety hazards.
