Temperature control device for electronic cigarette

Abstract

The invention relates to a temperature control device of an electronic smoking device. The temperature control device comprises a metal heating sheet which is used for heating cigarettes and a control device body which performs temperature control over the heating sheet, and the control device body adjusts the temperature of the heating sheet by collecting real-time resistance values of the heating sheet; the control device body comprises a power driving unit, an analog-digital conversion unit, a control unit and a real-time resistance detection unit; the power driving unit is electrically connected with a power source and the heating sheet separately, the control unit is electrically connected with the power driving unit and the real-time resistance detection unit separately, and the analog-digital conversion unit is used for converting a simulating signal output by the real-time resistance detection unit into a digital signal and then transmitting the digital signal to the control unit; the real-time resistance detection unit is used for detecting real time resistance of the heating sheet, and the control unit adjusts the output power of the power driving unit through the real-time resistance values of the heating sheet. The temperature control device of the electronic smoking device with the structure has the advantages of being accurate in temperature control, and convenient to use.

Description

technical field [0001] The invention relates to an electronic smoking appliance which heats cigarettes without burning them, in particular to a temperature control device for the electronic smoking appliance which adopts a metal heating sheet and can maintain a constant temperature state. Background technique [0002] Although everyone knows that smoking is harmful to health, at present, the number of smokers in the world still accounts for as much as one-fifth of the total population. This is because people have formed a habit of smoking, and they respond to each other, making it difficult to quit. In response to this situation, an electric heating smoking device, electronic smoking device, was born. This electronic smoking device provides consumers with nicotine and tobacco characteristic aroma by heating without burning tobacco to meet the smoking needs of smokers. , At the same time, it can greatly reduce the release of tar and harmful substances in mainstream smoke.

Problems solved by technology

However, in electronic smoking appliances, there is a certain error between the temperature detected by the temperature sensor and the temperature of the ceramic sheet itself. Due to the inaccurate temperature adjustment, it will affect the taste of consumers.

Secondly, the hardness of the ceramic heating plate is not large enough, so it is inconvenient to clean the excess tobacco leaves on the heating plate
