[0032] The nasal end 4-2 is of a conical structure, which is convenient for deepening into the nostril. In addition, the nasal end 4-2 is provided with a limiting ring 4-3, which can prevent the nasal end 4-2 from extending too far.

[0033] There is a sealing structure between the first end 2-1 of the connecting tube 2 and the pulse oscillation generator 1-2, a sealing structure between the second end 2-2 of the connecting tube 2 and the atomizer 3-2, and a sealing structure between the third end 2-3 of the connecting tube 2 and the air flow channel 4-1.
