[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0022] like Figure 1-5 Shown: A nozzle structure, including

[0023] The nozzle body 10 has an anti-slip sleeve 11 on its outer fixed sleeve and a flow cavity 22 formed inside the nozzle body 10;

[0024] A spray structure is rotatably disposed above the nozzle body 10. The spray structure includes a nozzle 12, a sleeve 14, a connecting pipe 15, and a spray head 16. The nozzle 12 is fixedly disposed inside the nozzle body 10 and communicates with the flow chamber 22. The rear end of the sleeve 14 is rotatably connected to the front end of the nozzle 12. The front end of the sleeve 14 is rotatably connected to the rear end of the connecting pipe 15. The spray head 16 is clamped in the connecting pipe 15.

[0025] The pressure regulating structure is movably arranged inside the sleeve 14 , and includes an adjusting column 18 and a propeller 19 . The adjusting column 18 is threadedly arranged inside the sleeve 14 , and the propeller 19 is fixedly arranged inside the adjusting column 18 .

[0026] By setting a pressure regulating structure in the spray structure, by setting the spray structure and the pressure regulating structure, by rotating the sleeve column 14, the regulating column 18 drives the propeller 19 to move in the connecting tube 15, and the propeller 19 helps the liquid medicine to penetrate. The regulating column 18 is close to the spray head 16 to make the liquid medicine close to the injection hole, and then the liquid medicine is ejected. At the same time, the regulating column 18 is away from the spray head 16 to make the liquid medicine away from the injection hole, and then the liquid medicine is atomized. The spherical design of the spray head 16 can adapt to the patient's nasal cavity, help the device fit the nasal cavity, thereby helping the liquid medicine contact the nasal mucosa, thereby improving the patient's comfort.

[0027] like Figure 3-5As shown, a threaded hole 23 is provided inside the sleeve column 14, the adjusting column 18 is a nail-shaped column, the surface of the adjusting column 18 is provided with threads, and the adjusting column 18 is threadedly connected to the threaded hole 23; a through hole is provided inside the adjusting column 18, and the propeller 19 is fixedly set in the through hole.

[0028] like Figure 1 、 3 As shown in Figures 4 and 5, the sleeve 14 is composed of two limiting rings and a long cylinder. The two limiting rings are respectively fixed on the outer wall surfaces at both ends of the long cylinder. The inner wall surface at the rear end of the connecting pipe 15 and the inner wall surface at the front end of the nozzle 12 are both limiting ring grooves matched with the limiting rings, and the two limiting rings are respectively embedded in the corresponding limiting ring grooves.

[0029] A swivel 17 is fixedly sleeved on the middle portion of the outer wall of the long cylinder of the sleeve column 14 , and sealing rings 20 are fixedly sleeved on the front and rear sides of the swivel 17 respectively.

[0030] like Figure 3 、 5 As shown, the spray head 16 is a spherical shell. A retaining ring is provided near the water inlet of the connecting pipe 15. The retaining ring is engaged with the front end of the connecting pipe 15. An annular notch 21 is provided on the curved surface of the spray head 16, and a small-aperture spray hole is provided within the annular notch 21. The front side of the spray head 16 is provided with a plurality of spray holes, each surrounded by an annular notch 21, and each of the small-aperture spray holes is provided within the annular notch 21.

[0031] Before use, control the rotation of the sleeve 14 between the connecting tube 15 and the nozzle 12 by turning the rotating ring 17. During the rotation process, be sure to hold the connecting tube 15 in place to prevent it from rotating. As the sleeve 14 rotates, the adjustment column 18 will thread out of the threaded hole 23 of the sleeve 14 and slide within the connecting tube 15. When the adjustment column 18 drives the propeller 19 to approach the spray head 16, the perforation of the adjustment column 18 faces the spray hole on the top curved surface of the spray head 16. At this time, the liquid concentration distance is too small. When the user presses the push bar 13 to force the liquid to flow from the circulation chamber 22 into the nozzle 12, the liquid seeps out of the propeller 19 and is ejected through the spray hole of the spray head 16 and the small-aperture spray hole of the annular notch. When the adjusting column 18 drives the propeller 19 away from the spray head 16, the gathering distance of the medicine liquid becomes larger, and the medicine liquid seeps out from the propeller 19 and passes through the injection hole of the spray head 16 and the small-aperture spray hole of the annular groove 21 to be atomized and sprayed. The cross-sectional position of the small-aperture spray hole of the annular groove 21 is close to a vertical state, and the medicine liquid passing through the injection hole will reach the deep part of the nasal cavity; the medicine liquid passing through the small-aperture spray hole will be soaked in the nasal mucosa. The spherical design of the spray head 16 can fit the patient's nasal cavity to prevent waste caused by the outflow of medicine liquid. At the same time, the spherical design of the spray head 16 can also prolong the contact time of the medicine liquid with the nasal mucosa by blocking the outflow of medicine liquid.

[0032] like Figure 1 and Figure 2 As shown, the anti-slip sleeve 11 is a hexagonal ring, the outer plane of the anti-slip sleeve 11 is fixedly connected to a curved pressing strip 13 , and the nozzle body 10 is fixedly arranged on the inner side of the anti-slip sleeve 11 .

[0033] By setting the anti-slip cover 11 and setting the pressing strip 13 outside the anti-slip cover 11, the pressing strip 13 fits the bent shape of the finger better. The finger can be placed on the pressing strip 13 and bent to achieve downward pressure. The pressing strip 13 is away from the nozzle 12 and the finger will not touch the nasal cavity when pressing, avoiding the breeding of bacteria and ensuring hygienic use.

[0034] A physiological seawater nasal sprayer includes a sprayer body. The above-mentioned nozzle structure is arranged above the sprayer body, making the equipment more hygienic and comfortable to use. The sprayer body is elastically connected to the bottom of the nozzle body 10. A spring is fixedly provided between the sprayer body and the nozzle body 10, and the sprayer body and the nozzle body 10 are elastically connected by the spring.

[0035] It is understood that the present invention is described by way of certain embodiments, and those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. Furthermore, under the guidance of the present invention, these features and embodiments may be modified to suit specific circumstances and materials without departing from the spirit and scope of the present invention.
