Low-temperature heat-not-burn electronic cigarette heating element and constant-temperature control device

Abstract

The invention discloses a low-temperature heat-not-burn electronic cigarette heating element and a constant-temperature control device. The device comprises the electronic cigarette heating element, abistable switch circuit, a heating constant-temperature circuit and a switching circuit. A heating wire of the electronic cigarette heating element can serve as a thermocouple, the bistable switch circuit, the heating constant-temperature circuit and the switching circuit are mounted on a circuit board in the electronic cigarette body, and a positive electrode of a lithium storage battery in theelectronic cigarette body is connected with the bistable switch circuit, the switching circuit and the heating constant-temperature circuit through wires. A positive electrode of the heating wire of the heating element is made of nickel-chromium alloy while a negative electrode is made of nickel-silicon alloy or any other materials which can be used as the thermocouple. By integration of the heating wire and the thermocouple, small size, compact structure and low cost are realized; due to reduction of connection points on a heating wire base plate, probability of faults is reduced correspondingly. In operation of the heating wire of the heating element, the heating wire can serve as the thermocouple to output signals to the heating constant-temperature circuit at pulse intervals, and the heating constant-temperature circuit controls the heating element to operate at a constant temperature.

Description

technical field [0001] The invention relates to the field of electronic cigarette application equipment, in particular to a low-temperature bake-not-burn electronic cigarette heating element and a constant temperature control device. Background technique [0002] Low-temperature bake-not-burn electronic cigarettes are mainly used for smoking cessation and replacing cigarettes. It has the same appearance and taste similar to cigarettes, and even has a lot more taste than ordinary cigarettes. It can also suck out smoke, taste and feeling like cigarettes. Electronic cigarettes do not have other harmful components such as tar and suspended particles in cigarettes, so they have relatively little impact on human health and are widely used. [0003] The heating element of the electronic cigarette is the main component of the electronic cigarette, and its working reliability is directly related to the use effect and service life of the electronic cigarette. In order to ensure the ...

AI Technical Summary

Problems solved by technology

The existing electronic cigarette thermocouple and the heating element belong to two different parts. In practical applications, the thermocouple needs to be connected to the substrate of the heating element separately, so it is not convenient for the miniaturization of the heating element, which will lead to the overall shape of the electronic cigarette The volume becomes larger, and it is inconvenient for users to carry; and the probability of failure increases correspondingly due to more connection points
