Please refer to fig. 1 to fig. 5, which are schematic diagrams of an atomizing device according to an embodiment of the present invention. The atomizer 99 includes a body 10, a seal 20, and a seal rod 30. The main body 10 is provided with an atomizing chamber 11 in which the atomizing assembly 40 is installed, and an air inlet path 12 and a suction path 13 which are respectively communicated with the atomizing chamber 11. The sealing member 20 and the sealing rod 30 are detachably sealed in the air inlet path 12 and the suction path 13, respectively. The ends of the sealing member 20 and the sealing rod 30 remote from the atomizing chamber 11 are exposed to the main body 10. When an external force is applied to one end of the sealing member 20 and the sealing rod 30 exposed out of the main body 10, the sealing member 20 and the sealing rod 30 are separated from the main body 10, and the air inlet path 12, the atomizing chamber 11, and the suction path 13 are conducted.

The sealing plug sets up a plurality of sealing washers, not only can promote holistic sealing performance, can also prevent that whole sealing plug from all pegging graft with the atomizing pipe interference to produce great resistance. The other end and the atomizing pipe clearance fit of sealing rod, rather than the whole all with the atomizing pipe interference grafting of sealing rod, the resistance is too big when can preventing that the sealing rod is whole to be pegged graft with the atomizing pipe interference. In addition, the deformation hole that the sealing plug was seted up can be for the sealing plug pegs graft and provide the deformation space when the atomizing pipe takes place to deform. The downthehole packing of deformation has imbibition piece, and imbibition piece can adsorb the liquid from seepage to the atomizing chamber in the stock solution chamber.
