CONTENT OF THE UTILITY MODEL

[0004] In order to solve the above problems, one of the purposes of the application is to provide a quick-release nozzle seat.

[0005] The quick-release nozzle seat provided by the application adopts the following technical scheme:

DETAILED DESCRIPTION

[0032] The following will be described in detail with reference to the accompanying drawings. Figures 1-5 The application is further described in detail.

[0033] The application discloses a nozzle, which refers to Figure 1 , Figure 2 , comprising a nozzle body 1, a nozzle core 2 mounted on the nozzle body 1, and a quick-release nozzle seat detachably connected to the nozzle body 1. In the embodiment, the nozzle body 1 and the quick-release nozzle seat are both plastic parts.

[0034] Referring to Figure 2 , Figure 3 , the nozzle body 1 has a mounting cavity 11, which is a circular chamber. A mounting sleeve 12 is coaxially fixedly arranged on the bottom inner wall of the mounting cavity 11. The mounting sleeve 12 is integrally formed with the nozzle body 1, and a gap is formed between the outer peripheral wall of the mounting sleeve 12 and the inner peripheral wall of the mounting cavity 11. The upper end surface of the mounting sleeve 12 has a sink groove 13. The nozzle core 2 is inserted into the mounting sleeve 12. The upper end of the nozzle core 2 is coaxially fixedly sleeved with a positioning ring 21, which is integrally formed with the nozzle core 2. The upper end surface of the positioning ring 21 is flush with the upper end surface of the nozzle core 2. The positioning ring 21 is clamped in the sink groove 13 and abuts against the upper end surface of the mounting sleeve 12. The lower part of the nozzle core 2 is exposed from the mounting sleeve 12. The lower end of the nozzle core 2 is coaxially provided with a liquid injection hole 22, which is communicated with the inner cavity.

[0035] Referring to Figure 2 , Figure 3 , Figure 4The quick-release nozzle holder includes a nozzle holder body 3 that is detachably connected to the nozzle body 1 and a nozzle pipe 4 that is detachably connected to the nozzle holder body 3. The nozzle pipe 4 is connected to an external water supply device. The lower end of the nozzle seat body 3 is coaxially provided with a liquid inlet cavity 31 for the upper part of the mounting sleeve 12 and the upper part of the nozzle core 2 to be inserted. The inner peripheral wall of the mounting cavity 11 is fixedly connected to a limiting block 14. The outer peripheral wall of the nozzle seat body 3 is provided with a vertical groove 32 for the limiting block 14 to slide along the vertical direction. The lower opening of the vertical groove 32 extends to the lower end face of the nozzle seat body 3. The upper inner wall of the vertical groove 32 is provided with a horizontal groove 33 for the limiting block 14 to slide along the circumference of the nozzle seat body 3. The bottom wall of the horizontal groove 33 away from the vertical groove 32 has a limiting groove 34 for the limiting block 14 to slide and be embedded. The top inner wall of the liquid inlet cavity 31 is fixed with a limiting ring 35 that abuts against the upper end face of the nozzle core 2. In this embodiment, the limiting ring 35 and the nozzle seat body 3 are fixed together. In other embodiments, the limiting ring 35 is a rubber ring.

[0036] The outer peripheral wall of the nozzle 4 has a mounting hole 41 that communicates with the inner cavity. The upper end of the nozzle seat body 3 is integrally fixed with a limiting wing plate 36. The limiting wing plate 36 has an assembly curved surface for the outer peripheral walls on both sides of the nozzle 4 to abut and fit. The upper end of the limiting wing plate 36 is integrally fixed with a mounting post 37. The mounting post 37 includes a connector 371 that protrudes from and is fixed to the assembly curved surface of the limiting wing plate 36 and is inserted into the mounting hole 41, and a limiting head 372 that is coaxially fixed to the upper part of the connector 371. The outer diameter of the limiting head 372 is larger than the inner diameter of the mounting hole 41. The upper end face of the limiting head 372 has a flow hole 373 that communicates between the liquid inlet chamber 31 and the inner cavity of the nozzle 4. The upper end of the limiting head 372 has a deformation groove 374 that extends to the connector 371, so that the limiting head 372 can deform and pass through the mounting hole 41. The deformation groove 374 communicates with the flow hole 373.

[0037] Reference Figure 2 , Figure 5 The upper end face of the limiting head 372 has an installation guide surface 375 for the inner wall of the mounting hole 41 to abut against, thereby forcing the limiting head 372 to deform, and the lower end face of the limiting head 372 has a disassembly guide surface 376 for the inner wall of the mounting hole 41 to abut against, thereby forcing the limiting head 372 to deform.

[0038] The implementation principle of the quick-release nozzle seat embodiment of the present application is as follows: when assembling the spray pipe 4 and the nozzle seat body 3, a force of mutual approaching is applied to the spray pipe 4 and the nozzle seat body 3, so that the installation guide surface 375 on the limiting head 372 abuts against the inner wall of the installation hole 41. In the pressing process, the limiting head 372 is forced to deform, so that the limiting head 372 smoothly passes through the installation hole 41. When the limiting head 372 is arranged in the inner cavity of the spray pipe 4, the limiting head 372 is deformed and reset, preventing the limiting head 372 from reversely slipping out of the limiting hole, thereby realizing the fixation of the spray pipe 4 and the nozzle seat body 3. When disassembling the nozzle seat body 3, a force of mutual moving away is applied to the spray pipe 4 and the nozzle seat body 3, so that the disassembly guide surface 376 on the limiting head 372 abuts against the inner wall of the installation hole 41. In the pulling-out process, the limiting head 372 is forced to deform, so that the limiting head 372 slips out of the installation hole 41.

[0039] In other embodiments, according to the installation requirements, the inclination angle of the assembly curved surface (inclination along the axial direction of the limiting wing plate 36, inclination angle is +8° / -8°) is set during the production of the nozzle seat body 3, so that after the assembly personnel directly install the nozzle seat body 3 on the spray pipe 4, the spray hole 22 axis of the nozzle core body 2 has an inclination angle, and there is no need to manually adjust the angle.

[0040] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application. Therefore, equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
