[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1 — Figure 3 :

[0033] A flushing spray gun includes a housing 1 with a water outlet 10 at the top and a core. The housing 1 has a switch hole 11 on its side wall. The core includes an outer tube 2 detachably connected to the housing 1. The top of the outer tube 2 has several outer tube outlet holes 20 circumferentially connected to the inner end of the water outlet 10. The bottom of the outer tube 2 is sealed with a water inlet connector 3. An inner tube 4 is disposed inside the outer tube 2. The top of the inner tube 2 has a columnar water outlet cavity 21 formed and connected to the outer tube outlet holes 20. An upper sealing sliding joint 40 is provided on the outer wall of the inner tube 4 near the top, abutting against the inner wall of the water outlet cavity 21. The bottom of the inner tube 4 penetrates the upper end of the water inlet connector 3 and is connected to the inside of the water inlet connector 3. A lower sealing sliding joint 41 is provided on the side wall near the bottom, which abuts against the inner wall of the water inlet connector 3. A return spring 5 is provided inside the outer tube 2 and sleeved on the outer wall of the inner tube 4. A lower abutting part 42 is provided on the side wall of the inner tube 4, which abuts against the upper end of the return spring 50. The lower end of the return spring 5 abuts against the upper end of the water inlet connector 3. An upper abutting part 43 is provided on the side wall of the inner tube 4, located above the lower abutting part 42. A hinge rod 6 extending out of the side wall of the outer tube 2 is provided between the upper abutting part 43 and the lower abutting part 42. A key cap 12 for pressing the hinge rod 6 is provided on the switch hole 11. When the key cap 12 is pressed, the hinge rod 6 drives the inner tube 4 to move downward, thereby connecting with the water outlet hole 20 of the outer tube.

[0034] During implementation, the core is installed inside the housing, and the hinge rod corresponds to the keycap 12. Pressing the keycap 12 moves the inner tube up and down. This method allows the core to adapt to different housings, giving it a wider range of applications.

[0035] When the user does not press, the reset spring 5 drives the lower abutment to move upward, that is, the inner tube slides upward, and the top of the inner tube abuts against the top of the outer tube 2, so that the water inside the inner tube will not flow out from the water outlet hole 20 of the outer tube on the water outlet chamber 21, and thus will not spray out from the top of the shell.

[0036] In the above structure, both lower ends of the inner tube are provided with sealing structures for the sliding process, namely the upper sealing sliding joint 40 and the lower sealing sliding joint 41, to ensure that there is no water leakage from the sliding joint during the sliding process.

[0037] Preferably, the outer tube 2 has a side opening 22 on its side wall for the end of the hinge rod 6 to extend out. The end of the hinge rod 6 is hinged to the lower end of the side opening 22. The end of the hinge rod 6 near the hinge point extends toward the inner tube 4 to form a fork-shaped abutment rod 60. The bottom of the abutment rod 60 abuts against the upper end face of the lower abutment part 42.

[0038] In the above structure, the end of the hinge rod 6 is connected to the side opening of the outer tube 2, so that after the inner tube is installed, the end of the hinge rod 60 can be directly inserted and abutted against the side wall of the inner tube, which effectively facilitates installation.

[0039] Preferably, both the upper abutment portion 43 and the lower abutment portion 42 are annular structures, and the end of the abutment rod 60 is a "T" shaped structure.

[0040] During implementation, the T-shaped structure of the abutment 60 abuts against the lower end of the upper abutment part 43 and the upper end of the lower abutment part 42 respectively, so that the rotating abutment can follow the rotating hinge rod to drive the inner tube to slide up and down in a timely manner.

[0041] Preferably, the top of the housing 1 is provided with an abutting step 13 for inserting and fixing the top side wall of the outer tube 2, and the side wall of the top of the outer tube 2 is provided with a first sealing ring 14 that abuts against the inner side wall of the abutting step 13.

[0042] In the above structure, the abutting step 13 can effectively limit the outer tube inside the housing 1, ensuring that the inner tube will not loosen during the sliding process. The first sealing ring 14 ensures that there is no water leakage between the outer tube and the object.

[0043] Preferably, a sealing gasket 23 is embedded in the top of the outer tube 2. When the keycap 12 is not pressed, the reset spring 5 drives the top of the inner tube 4 to abut against the lower end face of the sealing gasket 23.

[0044] In the above structure, the sealing gasket 23 is made of rubber. When the top of the inner tube 4 abuts against the bottom of the sealing gasket 23, the sealing gasket 23 is subjected to a certain compression deformation, thereby achieving the sealing effect.

[0045] Preferably, a nozzle seat 7 is screwed to the water outlet at the top of the housing 1, and the nozzle seat 7 has a plurality of nozzles 70 circumferentially opened.

[0046] During use, the top of the housing is detachably fitted with the nozzle seat 7, and the several nozzles 70 form a multi-water spray effect.

[0047] Preferably, the lower sealing sliding joint 41 includes an installation ring 30 embedded in the inner wall of the water inlet connector 3, and the upper end of the installation ring 30 abuts against a second sealing ring 31 sleeved on the bottom side wall of the inner tube 4.

[0048] During implementation, the inner tube is pre-installed inside the outer tube, then the second sealing ring 31 is placed, and then the installation ring 30 is locked to prevent the second sealing ring 31 from loosening as the inner tube slides up and down.

[0049] Preferably, the side wall at the bottom of the outer tube 2 is fixedly connected to the inner wall at the bottom of the housing 1 by means of threads. The outer tube 2 and the housing 1 are assembled by means of threads, which makes disassembly and assembly more convenient.

[0050] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
