Preferably, the air suction hole 3211 is formed in the sealing post 3212, the side wall 12 of the sealing post 3212 is provided with an opening communicated with the air suction hole 3211, and when a user sucks the air suction hole 3211, the air flow mixed with aerosol passes through the first air passing hole from the air outlet channel 311 and can enter the air suction hole 3211 from the opening, so that the user sucks the air. That is, the suction hole 3211 of the suction nozzle 321 forms a non-through air passage with the air outlet passage 311 so as not to be sucked by the user to condensate on the air outlet passage 311.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
