When the user stops pumping, the negative pressure in the air outlet channel 121 is evacuated, and then the condensate in the air outlet channel 121 flows downwards along the air outlet channel 121, and can be stored in the atomizing base 22 through the cavity 2271 due to the existence of the cavity 2271 and the existence of the through hole in the cavity 2271; preferably, in the pipetting vent 2261; the condensate can be absorbed by the liquid absorbing air-exchange grooves 2261 of the atomizing base 22 by capillary force, thereby preventing the condensate from flowing out of the atomizing housing 10.

During transportation and storage, the atomized liquid leaks from the porous pores of the porous body 231 to the atomizing holes 2223 through the lower liquid holes 225 due to external temperature, air pressure, mechanical vibration and the like, and the atomized liquid stored in the atomizing holes 2223 can be stored in the liquid suction and air exchange groove 2261 of the atomizing base 22 through the cavity 2271 when flowing upwards.
