An electronic cigarette capable of automatic temperature control

Abstract

The invention provides an electronic cigarette capable of automatically controlling temperature. The electronic cigarette capable of automatically controlling temperature comprises an atomization wire and a power source which are electrically connected, and is characterized in that an MOS pipe driving circuit (10) is further connected between the atomization wire and the power source. The electronic cigarette further comprises an operational amplifier and a single-chip microcomputer which are electrically connected, the two ends of the atomization wire are electrically connected with a forward input end and a reverse input end of the operational amplifier respectively, an output end of the operational amplifier is electrically connected with a voltage signal collecting pin of the single-chip microcomputer, an output duty ratio pin of the single-chip microcomputer is electrically connected with the MOS pipe driving circuit, and the output of the MOS pipe driving circuit is electrically connected with the atomization wire. The intensity of the voltage loaded to the atomization wire is controlled according to the result of the resistance value of the atomization wire changing along with the temperature after conversion, collection, amplification and processing, then the temperature of the atomization wire is adjusted, the purposes of automatic detection and temperature control are realized, individual experience is provided for a user after use, generation of harmful matter is reduced to some extent, and the electronic cigarette capable of automatically controlling temperature has good market development prospects.

Description

technical field [0001] The invention relates to a smoking cessation tool, in particular to an electronic cigarette capable of automatic temperature control. Background technique [0002] Electronic cigarettes, also known as electronic cigarettes, are mainly used to quit smoking and replace cigarettes. It has the same appearance and taste similar to cigarettes, and even tastes much more than ordinary cigarettes. It can also suck out smoke and smell like cigarettes Follow the feeling. Its working principle is that the atomizing wire is heated by electricity, and the electric energy is converted into heat energy to heat the e-liquid. When the e-liquid is heated to a certain temperature, it will be volatilized and atomized to produce smoke. The existing electronic cigarette has no automatic temperature control. function, the heating temperature of the atomizing wire cannot be precisely controlled. Excessively high atomization temperature (over 400°C) will cause the chemical rea...

Problems solved by technology

Its working principle is that the atomizing wire is heated by electricity, and the electric energy is converted into heat energy to heat the e-liquid. When the e-liquid is heated to a certain temperature, it will be volatilized and atomized to produce smoke. The existing electronic cigarette has no automatic temperature control. function, the heating temperature of the atomizing wire cannot be precisely controlled. Excessively high atomization temperature (over 400°C) will cause the chemical reaction of the e-liquid to produce harmful substances to the human body and damage the health of the user; at the same time, different e-liquids The oil temperature has different tastes. Due to the lack of automatic temperature control function, the development of existing electronic cigarettes is hindered when they meet the needs of different groups of people.
