Heating device of electronic smoking set and control method of device

Abstract

The invention relates to a heating device of an electronic smoking set and a control method of the device. A microcontroller of the heating device of the electronic smoking set is electrically connected with a buck-boost bridge circuit, a heating unit resistance value sampling circuit, a heating unit and a heating unit resistance value detection module in sequence and then is connected back to the microcontroller; the heating unit resistance value sampling circuit is connected with the heating unit resistance value detection module, a feedback circuit is connected between the buck-boost bridge circuit and the heating unit, and the feedback circuit is connected back to the microcontroller; when the electronic smoking set is used, the temperature of the heating unit is changed, the resistance value is also changed correspondingly, and the heating unit resistance value detection module detects the resistance value of the heating unit, converts the resistance value into corresponding temperature electric signals, and transmits the signals to the microcontroller; the microcontroller compares the temperature electric signals with a set temperature value and sends control signals to the buck-boost bridge circuit, so that the output voltage of the buck-boost bridge circuit is changed, the power of the heating unit is also changed, and accordingly the temperature of the heating unit is adjusted to be stable.

Description

technical field [0001] The present invention relates to the technical field of an electronic smoking appliance, in particular to a heating device of an electronic smoking appliance and a control method thereof. Background technique [0002] Ordinary cigarettes emit cigarette smoke for the smoker to inhale when burning with an open flame, and when the cigarette is burned with an open flame, it will decompose and produce harmful substances such as smoke tar, carbon monoxide, phenol, nitrogen oxides, olefins, polycyclic aromatic hydrocarbons, etc. , these substances can seriously damage human health. [0003] In order to avoid a large amount of harmful substances produced by cigarettes and enjoy the unique taste of cigarettes, an electronic smoking device that can assist smoking has been produced on the market. Electric heating, the tobacco product is baked at a temperature lower than the temperature at which the tobacco product can burn until it smokes, and the smoker can inh...

AI Technical Summary

Problems solved by technology

[0004] Existing electronic smoking sets, no matter in the standby or smoking state, generally heat the outer wall of the cigarette smoke body through the heating tube at a constant voltage. The heat conduction is relatively slow at the beginning, and the overall temperature of the cigarette smoke body rises slowly, resulting in a small amount of smoke sucked out. After the temperature rises, because the heating cup is close to the outer wall of the cigarette smoke body and continues to generate heat, the heat conducts slowly through the outer wall of the cigarette smoke body to the inside, causing the temperature on the side of the outer wall of the cigarette to be too high, and it is easy to burn and produce a burnt smell
