An electronic cigarette and its heating element temperature control method

Abstract

An electronic cigarette and a method for controlling the temperature of its heating element. The electronic cigarette includes: a heating element (1) used for atomizing e-liquid and whose resistance value increases as the temperature increases; a power supply circuit for supplying power to the heating element (1) (2); for detecting the resistance value of the heating element (1), to obtain the voltage adjustment circuit (3) of the current temperature of the heating element (1); the voltage adjustment circuit (3) is also used for when the current temperature is greater than the first preset temperature When the set value is lower than the second preset value, the power supply voltage of the heating element (1) is adjusted so that its heating temperature is maintained within the preset temperature range; ) heating resistance to monitor and control the temperature of the heating element (1), so as to keep its temperature within a suitable temperature range.

Description

technical field [0001] The invention relates to the technical field of electronic cigarettes, in particular to an electronic cigarette and a method for controlling the temperature of a heating element thereof. Background technique [0002] E-cigarettes are a relatively common imitation cigarette electronic product, mainly used for smoking cessation and replacement of cigarettes. The atomizing heating wire is the heating device used to atomize the e-liquid in the electronic cigarette. When the electronic cigarette is working, the battery supplies power to the atomizing heating wire, and the heating wire is energized to generate heat. The atomized e-liquid forms simulated smoke, so that users can have a feeling similar to smoking real cigarettes when smoking electronic cigarettes. [0003] At present, the heating wire used for atomizing e-liquid in electronic cigarettes is mostly made of heating alloys, such as nickel-chromium alloys, iron-chromium-aluminum alloys, etc., whic...

Problems solved by technology

[0006] The present invention aims at the problem existing in the prior art that the electronic cigarette cannot know the temperature change of the heating wire by detecting the resistance of the heating wire, so as to control the temperature of the heating wire when the temperature is too high, and detect by setting a temperature sensor in the electronic cigarette The temperature change of the heating wire, in order to control the temperature of the heating wire, the technical problem of increasing the volume and design complexity of the internal circuit of the electronic cigarette, provides a temperature control method for the electronic cigarette and its heating parts, and realizes the heating parts in the atomizer. When heating, the heating resistance of the heating element is detected to monitor and control its temperature, so that the temperature will not be too high. At the same time, there is no need to add a temperature sensor in the electronic cigarette, which will not increase the volume of the internal circuit of the electronic cigarette and complicate the design. degree of technical effect
