[0026] A water outlet pipe 4 is installed on the upper connecting seat 1 to match the water inlet pipe 3;

[0027] Sealing sleeve 5: A hollow sealing sleeve 5 is installed at the lower end of the water outlet pipe 4;

[0028] Sealing member 6: a sealing member 6 which can be sealed with the sealing sleeve 5 is arranged in the water outlet pipe 4, the lower surface of the sealing member 6 is a spherical arc surface, and a mounting groove 7 is provided on the top of the sealing member 6;

[0029] Spring 8 : A spring 8 is arranged in the water outlet pipe 4 , and one end of the spring 8 is fixedly connected to the sealing member 6 , and the other end of the spring 8 is fixedly arranged in the mounting groove 7 .

[0030] It can be seen from this embodiment that a water outlet pipe 4 is installed on the upper connecting seat 1, and a water inlet pipe 3 is installed on the lower connecting seat. A sealing sleeve 5 is arranged between the water inlet pipe 3 and the water outlet pipe 4. The sealing sleeve 5 is made of rubber material. The sealing sleeve 5 is cooperated with a spring 8 and a sealing member 6, and has a sealed state and an open state. In the open state, water inlet effect is achieved, and in the closed state, the sealing effect is excellent.

[0031] Embodiment 2:

[0032] This embodiment provides a coupler water supply mechanism, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0033] A protrusion 15 is integrally formed on the bottom of the sealing member 6 , and the protrusion 15 extends to the hollow portion of the sealing sleeve 5 .

[0034] It can be seen from the present embodiment that a protrusion 15 is integrally formed at the bottom of the sealing member 6. The integrally formed structure has high strength and long service life. The protrusion 15 extends to the hollow part of the sealing sleeve 5. During the coupling process of the upper connecting seat 1 and the lower connecting seat 2, the water inlet pipe 3 is first sealed and connected to the sealing sleeve 5, and then the protrusion 15 is pushed open. The protrusion 15 drives the sealing member 6 to move upward, and the sealing member 6 is separated from the sealing sleeve 5, effectively opening the water injection channel. During the separation process of the upper connecting seat 1 and the lower connecting seat 2, the water inlet pipe 3 moves downward in the hollow part of the sealing sleeve 5. At this time, the compound force of the spring 8 enables the sealing member 6 to form a sealed partition with the sealing sleeve 5 to seal the water, and then the water inlet pipe 3 is separated again, and no residual water is retained. The design of the protrusion 15 does not need to consider the water pressure, has low requirements on the water pump, and has a wide range of applications.

[0035] Embodiment 3:

[0036] This embodiment provides a coupler water supply mechanism, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0037] The sealing sleeve 5 comprises:

[0038] The outer wall 9 is sealed with the inner wall of the water outlet pipe 4;

[0039] An inner ring wall 10 is formed by extending upward from the bottom of the outer wall 9 in the outer wall 9, and a lower receiving channel adapted to the water inlet pipe 3 and for inserting the water inlet pipe 3 is formed at the lower part of the inner ring wall 10;

[0040] A gap 11 is provided between the outer wall of the inner ring wall 10 and the inner wall of the outer wall 9;

[0041] Under the action of the spring 8, the seal 6 has a sealing state and an open state. In the sealing state, the seal 6 forms a sealing partition with the upper part of the inner ring wall 10 through the spring 8. In the open state, the seal 6 is separated from the upper part of the inner ring wall 10 to form a water outlet gap.

[0042] It can be seen from this embodiment that since the outer wall 9 and the inner ring wall 10 are integrated with a gap 11, the water inlet pipe 3 has little insertion resistance and is smoother, and has an outstanding and reliable sealing effect. Furthermore, the rubber sealing sleeve 5 has high processing precision, a simple structure, and does not require secondary processing and demolding, and is easy to process.

[0043] In order to save costs, the plugging stability of the water inlet pipe 3 and the smoothness of the cooperation between the upper connecting seat 1 and the lower connecting seat 2 are improved to avoid jamming.

[0051] It can be seen from this embodiment that the support ring 12 is partially arranged higher than the outer wall 9, which is beneficial to increase the area of ​​the support ring 12, that is, the matching area with the seal 6, effectively ensures the sealing performance, and eliminates the problem of excessive falling of the seal 6.

[0052] Embodiment 6:

[0053] This embodiment provides a coupler water supply mechanism, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0054] The outer periphery of the outer wall 9 is also provided with an upturned annular wall 13 which turns up from the bottom of the outer wall 9 outwards, and the lower end of the pipe wall of the water outlet pipe 4 is provided with a limiting step 14 which is adapted to the upturned annular wall 13 .

[0055] It can be seen from this embodiment that by providing the upwardly tilted annular wall 13 and the limiting step 14 , the sealing sleeve 5 can be accurately limited in position, which is convenient for assembly and effectively improves the compatibility with the water outlet pipe 4 .
