An automatic temperature control platinum wire electronic cigarette

Abstract

The invention provides an automatic temperature control platinum wire electronic cigarette, which is characterized by comprising an atomization wire, a sampling circuit, a singlechip microcomputer and a power adjustment circuit, wherein a resistance value of the atomization wire varies positively along with a temperature value, the atomization wire is a platinum wire, the sampling circuit is connected with the atomization wire in series, the singlechip microcomputer is connected with the output end of the sampling circuit and capable of processing analog signals outputted by the sampling circuit, the power adjustment circuit is connected with the singlechip microcomputer and controlled by the singlechip microcomputer, and the output end of the power adjustment circuit is connected with the sampling circuit. According to the invention, the platinum-wire atomization wire with a high oxidation resistance and a high temperature coefficient of resistance is adopted, a real-time current value at both ends of the atomization wire can be acquired more accurately when the temperature of the atomization wire changes in the long-time using process, the real-time current value is converted into a real-time temperature value through conversion, acquisition, amplification and processing, the singlechip microcomputer controls and adjusts the power loaded on the atomization wire through a result of comparing the real-time temperature value and a preset temperature value, thus the temperature of the atomization wire is adjusted, and heat preservation is carried out after the preset temperature is reached. The automatic temperature control platinum wire electronic cigarette has function of automatic detection, temperature control and constant temperature.

Description

technical field [0001] The invention relates to a smoking cessation tool, in particular to an automatic temperature-control platinum wire electronic cigarette. 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 ...

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.
