A guide cover 3 is arranged above the atomizing disperser 2, and the aerosol is guided to a sublingual nozzle by a connecting pipe 12 on the upper part of the guide cover 3. More specifically, the external air of the pressure regulating pipe on the upper cover 7 is introduced into the body 1 by the air suction pipe 14 on the flow guiding cover 3, the flow rate of the air entering into the body 1 is regulated by the regulating valve 4 on the pressure regulating pipe, and the external air and the atomized liquid drops form aerosol and then are introduced into the sublingual nozzle 8 through the connecting pipe 12 on the flow guiding cover 3.

In the structure, the lower pot head of breathing pipe 14 is established on atomizing deconcentrator 2, and great granule among the vaporific particle touches the inner wall of breathing pipe 14 and then liquefies, flows into the stock solution chamber once more along the lateral wall, and simultaneously, the vaporific particle of less particle diameter gets into sublingual nozzle, and under this kind of circumstances, the vaporific particle of selecting less particle diameter treats, can effectively improve treatment, improves the absorption rate of liquid medicine, has practiced thrift the liquid medicine.

Referring to fig. 6, in the above-mentioned sublingual atomizer structure, the user bites the end of the delivery tube 83 under the tongue, and during the operation of the atomizer, external air is introduced into the body by the air compressor, and aerosol is continuously generated, and during inhalation, the aerosol flows under the tongue of the user through the spray opening of the delivery tube 83, specifically, is sprayed from the spray opening at the top of the delivery tube 83 to the sublingual surface of the user, and is sprayed to the base of the tongue of the user through the spray opening at the end of the delivery tube 83.

Also in use, saliva produced sublingually enters through the delivery tube 83, then through the baffle wall into the mouthpiece 84, and exits along the discharge tube 82. In addition, the user can also put the delivery tube on the tongue for use, namely the mouth, the aerosol can be sprayed to the palate and the throat of the user, and the flow direction of the airflow is basically the same as that of the airflow, namely the function of the existing inhalation type atomizer is realized.
