Description

Technical Field

[0001] The utility model relates to the field of atomization equipment, in particular to an atomization device. Background Art

[0002] Atomizers are mainly used to heat and atomize liquids to form aerosols, such as electronic atomizers. Traditional atomizers mostly use a heater to heat an aerosol-generating matrix to form aerosols, but the problem of mismatch between the heating efficiency of the heater and the supply speed of the aerosol-generating matrix has always existed. If the aerosol-generating matrix is ​​not supplied in time, the heater will dry burn without oil, causing thermal runaway of the heater, which will seriously affect the service life of the heater.

[0003] In the related art, the method to avoid thermal runaway of the heating body is generally to control the output power of the power supply to the heating body after measuring the temperature through a temperature sensor. However, this method has a time delay and a slow temperature response speed. In addition, many temperature control circuits will directly disconnect the power circuit when the heating body runs away from heat. It is necessary to wait for cooling before restarting the atomization device, which affects the smoking experience. Utility Model Content
