Dynamic switching method of electronic cigarette system

Abstract

The invention discloses a dynamic switching method of an electronic cigarette system. A USB interface of the electronic cigarette is connected with a computer through a USB line; switching the UART function of the electronic cigarette through a discrimination software program in a microcontroller (MCU) stored in the electronic cigarette; wherein the step of judging the execution of the software program has the technical advantages that (1) a UART circuit is connected to a USB interface of the electronic cigarette from the interior of the electronic cigarette; the computer supplies power to theelectronic cigarette through the USB line so as to charge the electronic cigarette; (2) the UART of the electronic cigarette is communicated with the computer, the application requirements of factoryproduction testing, health management and the like are met, and (3) when the USB interface of the electronic cigarette is connected with the computer through the USB line to charge the computer, a message which cannot be identified by the device does not appear on a computer screen.

Description

technical field [0001] The present invention relates to a dynamic switching method of an electronic cigarette system, in particular, after the USB interface of an electronic cigarette is connected to a computer through a USB cable, the software program stored in the microcontroller (MCU) in the electronic cigarette is used to determine the right A method for switching the UART function of the electronic cigarette. Background technique [0002] Electronic atomizer (English: VAPE or Electronic cigarette), commonly known as "electronic cigarette", is an atomizer powered by a rechargeable lithium polymer battery. Liquid, E-liquid or E-juice; e-liquid containing propylene glycol, vegetable glycerin, flavoring or nicotine). E-cigarettes do not need to be burned, they only produce "steam" without tar and carbon monoxide, which can reduce the impact of some traditional cigarettes on the body, and make smokers who replace cigarettes with e-cigarettes stay away from carcinogens in ci...

Problems solved by technology

However, when the USB interface of the e-cigarette is connected to a computer for charging, and the operating system is Windows, a message that the device cannot be identified will appear on the computer screen

[0006] If the USB interface of the e-cigarette has UART function, and the UART function is turned on, when the e-cigarette is connected to a Windows computer, a message that the device cannot be identified will appear on the computer screen

The reason for the above phenomenon is that the USB interface of the Windows computer is a USB signal. If the USB interface of the e-cigarette receives a UART signal, it will cause the Windows computer to fail to recognize and an unidentifiable message will pop up.
