Gas flow transducer 50 can according to the negative pressure value in user's smoking process, feedback voltage signal to temperature control plate 40,
Temperature control plate 40 is supplied to the amplitude of variation of the output power of atomizer according to voltage signal and actual measurement resistance value, regulation.Work as user
When smoking speed slows down, negative pressure value is smaller, and actual measurement resistance value has the tendency that beyond target value, therefore the output power drop of power supply unit
Low, temperature is excessively high or amount of smoke is excessive to prevent, and chokes user；When user's smoking speed quickening (throughput increasing), bear
Pressure value is larger, and actual measurement resistance value has lower than target value trend, and power supply unit output power substantially rises, with compensation since air-flow is from mist
Change the heat that device heat generating components is taken away, guarantees that temperature is accurate, the amount of smoke in guarantor unit's gas volume is consistent, and mouthfeel is consistent.
The above description is only an embodiment of the present invention, is not intended to limit the scope of the invention, all to utilize this hair
Equivalent structure or equivalent flow shift made by bright specification and accompanying drawing content is applied directly or indirectly in other relevant skills
Art field, is included within the scope of the present invention.
