DETAILED DESCRIPTION

[0035] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clear and understandable, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0036] See also Figures 1 to 10 , a self-priming and leak-proof foaming nozzle, comprising a nozzle body 1.

[0037] The nozzle body 1 is tubular, with one end being the water inlet end 11 and the other end being the spraying end 12. A mounting structure 13 is provided in the middle. The nozzle body 1 is mounted on the toilet through the mounting structure 13, and the portion from the spraying end 12 to the mounting structure 13 extends into the toilet pot surface, forming a built-in section 14, while the portion from the water inlet end 11 to the mounting structure 13 is outside the toilet pot surface, forming an external section 15.

[0038] In one embodiment, the mounting structure 13 is a support seat arranged on the periphery of the nozzle body 1, and the periphery of the external section 15 is provided with a conical pad 2, a flat pad 3 and a mounting nut 4. After installation, the support seat and the conical pad 2 clamp the ceramic surface of the toilet, and the support seat is located inside the toilet pot surface.

[0039] The nozzle body 1 is provided with a liquid inlet 16 for the entry of the foaming liquid on the periphery of the external section 15, and an air suction hole 171 is provided on the periphery of the internal section 14. The nozzle body 1 is also provided with an air intake channel 17, one end of the air intake channel 17 is connected to the air suction hole 171, and the other end extends to the negative pressure generating area in the external section 15, thereby realizing the self-inhalation function.

[0040] In one embodiment, the external section 15 has a constriction near the water inlet end 11. The nozzle body 1 forms the negative pressure generating zone at the outlet of the constriction. The outlet 172 of the air inlet channel 17 extends near the outlet of the constriction. Furthermore, the outlet 172 of the air inlet channel 17 opens toward the discharge end 12, preventing water entering the nozzle body 1 from being ejected through the air inlet channel 17.

[0041] Optionally, the liquid inlet 16 is arranged on the outer periphery of the neck and forms a docking joint that can be docked with an external hose.

[0042] On the basis of the above embodiment, in order to reduce the difficulty of forming the air inlet channel 17, the self-air-inhaling leak-proof foaming nozzle also includes an air intake pipe 5, and the outer periphery of the air intake pipe 5 is provided with an axial groove 51. The air intake pipe 5 is installed in the nozzle body 1, and the internal space of the air intake pipe 5 is connected to the constriction and the ejection end 12 to form a foam forming cavity. The air inlet channel 17 is formed between the axial groove 51 and the inner wall of the nozzle body 1, and the axial groove 51 is provided with a notch at one end close to the constriction, constituting an air outlet 172 of the axial groove 51. Preferably, a baffle is provided on the outer periphery of the outlet of the constriction, and the baffle is spaced opposite to the notch of the axial groove 51 and constitutes the air outlet 172 of the air inlet channel 17.

[0043] In another embodiment, the spout end 12 is mounted with an extension nozzle 6, which not only improves the mixing of the foam-generating material but also facilitates the dispensing of foam to a predetermined location. Preferably, the extension nozzle 6 is press-fitted to the spout end 12 via a front nut 7, resulting in a simple and secure mounting structure 13. Furthermore, in other embodiments, the extension nozzle utilizes a ball-shaped mounting structure 13, forming an angle-adjustable swinging spout, allowing for flexible adjustment of the foam dispensing angle.

[0044] The utility model sets the air suction hole 171 in the built-in section 14 of the nozzle body 1, that is, after installation, the air suction hole 171 is located inside the toilet pot surface. Even if the air suction hole 171 drips or leaks, the water will flow into the toilet pot surface, which solves the problem that the traditional nozzle air suction hole 171 is set outside the toilet pot surface, causing damage to electronic components or moisture on the toilet installation floor.
