[0030] Example

[0031] like Figure 1 As shown, this embodiment discloses an air intake structure for a nasal spray, which is disposed on the body of the nasal spray. Specifically, the air intake structure of this embodiment includes: a plug mounting cavity 7, a filter plug 2, and a filter element 6. The plug mounting cavity 7 is disposed on the body of the nasal spray and communicates with the interior of the nasal spray body. The filter plug 2 is installed inside the plug mounting cavity 7, and the filter element 6 is installed on the filter plug 2.

[0032] Specifically, the filter plug 2 is provided with a filter element mounting cavity and a plug air inlet 4 communicating with the filter element mounting cavity, and the filter element 6 is installed in the filter element mounting cavity, such as... Figure 3 As shown. When the nasal spray is in use, outside air enters the spray unit through the air inlet 4 and filter 6 in sequence. The filter 6 filters the air entering the spray unit, such as... Figure 3 As shown.

[0033] The filter element 6 can be made of materials with water absorption properties such as activated carbon or sponge. In this embodiment, the filter element 6 is made of sponge material, which not only has water absorption properties, but also can prevent dust from entering the nasal sprayer.

[0034] In addition, such as Figure 2 As shown, an end plate is provided on the side of the nozzle mounting cavity 7 near the inside of the nasal spray body. The end plate has an air inlet 5 that communicates with the inside of the nasal spray body. The end plate can limit the filter element 6 to prevent it from falling into the nasal spray body. The filtered air enters the nasal spray body through the air inlet 5.
