Definitions
- the aerosol generating system is usually composed of an aerosol generating device and an aerosol generating product.
- the aerosol generating product is inserted into the aerosol generating device, and the heating module of the aerosol generating device heats and bakes the aerosol generating product, thereby generating aerosol for the user to inhale.
- the heating module does not directly heat and bake the aerosol generating product, but heats and bakes the aerosol generating product by heating the surrounding air and using the high-temperature air.
- the generated aerosol is mixed with the high-temperature air and inhaled. There is a certain distance between the heating module of the aerosol generating device and the aerosol generating product.
- the first parameter includes a first compensation coefficient
- a method for obtaining the first compensation coefficient includes:
- the first compensation coefficient is obtained according to the expected temperature and the first detected temperature.
- the first parameter is equal to the product of the first compensation coefficient, the second compensation coefficient and the third compensation coefficient.

- FIG1 it is a schematic diagram of the structure of an electronic cigarette.
- the heating module When the electronic cigarette is working, the heating module is powered on. At this time, the strip-shaped heating conductor in the heating module generates heat, thereby heating the honeycomb-shaped ceramic body 5. The air is heated, and the hot air flows to the tail end of the cigarette 1, the cigarette 1 is heated, and aerosol is generated.
- the heating module includes a strip-shaped heating conductor and a honeycomb-shaped ceramic body 5.
- the wire 4 is electrically connected to the heating conductor through the airway inside the electronic cigarette.
- the heating module itself has a large mass. When the heating module is heated, the support member 2 of the electronic cigarette in contact with the heating module and the heating module itself will absorb a certain amount of heat.
- heating conductor's own TCR for temperature control means controlling the temperature by changing its own resistance. It is necessary to determine the resistance of the heating conductor at the reference temperature (25°C) and its own TCR value (TCR is the abbreviation of temperature coefficient, which indicates the relative change of resistance when the temperature changes by 1 degree).
- Rt target resistance
- the heating conductor After the machine is powered on, the heating conductor starts to heat up. After time t1, it reaches the set temperature T and then starts to keep warm until t3. The preheating is completed and the temperature starts to drop.
