Description

Technical Field

[0001] This utility model relates to the field of nasal irrigator technology, specifically to a nasal irrigator atomizing nozzle structure. Background Technology

[0002] A nasal irrigator is a tool used to clean the nasal cavity. It typically uses pressure to deliver saline solution into the nostrils, flowing through the nasal vestibule (the part exposed outside the head), sinuses, and nasal passages, bypassing the nasopharynx, and exiting either through one nostril or the mouth. Through this pathway, the saline solution's own bactericidal properties and the force of the water flow remove accumulated pathogens and dirt from the nasal cavity, restoring its normal physiological environment and self-detoxification function, thus protecting the nasal cavity. However, existing nasal irrigators often produce large and uneven mist particles, resulting in irregular spray patterns that affect the cleaning effect and reduce user comfort. Therefore, a new atomizing nozzle structure is needed to address these issues. Utility Model Content

[0003] The purpose of this invention is to provide a nasal irrigator atomizing nozzle structure to solve the above-mentioned technical problems. This invention has the advantages of producing small and uniform mist particles, regular spray pattern, good cleaning effect, good user comfort, and strong practicality.

The liquid suction channel 7 extends from the connector 9 through the limiting seat 10, the support seat 11, and the aspiration column 12. The aspiration column 12 is used to connect to the nasal irrigator bottle. The connector 9 has a liquid outlet, and the aspiration column 12 has a liquid inlet. The liquid inlet, the liquid outlet, the aspiration channel 7, and the atomizing channel 5 are interconnected.

[0035] like Figure 2 and Figure 5 As shown, the insertion post 9 includes an upper insertion post 13, a middle insertion post 14, and a lower insertion post 15 arranged sequentially from top to bottom. The liquid suction channel 7 extends from the middle insertion post 14 through the lower insertion post 15, the limiting seat 10, the support seat 11, and the suction post 12.

[0036] like Figure 5 As shown, the outer side wall of the limiting seat 10 is provided with a limiting protrusion 16 and a pressing part 17, and the pressing part 17 is located at the upper and lower ends of the limiting protrusion 16.

[0037] like Figure 2 and Figure 5 As shown, the support base 11 includes a locking part 18 and an abutting part 19. The locking part 18 is connected to the inside of the spray head cover 2.
