An annular elastic piece mounting groove is formed in the atomizing cup 92, and the elastic piece 91 is an annular elastic silica gel piece and is arranged in the annular elastic piece mounting groove. The binding surface is positioned below the third gap. In a natural state, the contact surface of the elastic member 91 is tightly contacted with the lower end surface of the isolation extension 931, and when the air is sucked, the contact surface is pressed downwards to deform, and the deformed contact surface and the lower end surface of the isolation extension 931 form the air flow yielding gap.
When a user inhales air from the air outlet 12, the air coming from the outside enters from the air inlet 11 under the action of negative pressure, the silica gel sheet generates sinking deformation under the action of negative pressure to communicate the air inlet 11 with the air outlet 12, the air coming from the outside is mixed with the atomizing gas in the atomizing cavity 31 through the third gap 92, and finally the air is exhausted from the air outlet 12;
when the user does not inhale at gas outlet 12, gas outlet 12 does not have negative pressure, and silica gel thin slice 91 recovers, does not communicate gas inlet 11 and gas outlet 12 for the air that the external world came in can not enter into atomizing chamber 31, stops in third clearance 92 department, and the gaseous gas of atomizing chamber 31 does not flow promptly, avoids the volatile substances in atomizing chamber 31 to volatilize.
