[0024] The utility model will be described in detail below in combination with the drawings and specific embodiments. The embodiments are implemented on the premise of the technical scheme of the utility model, and detailed implementation modes and specific operation processes are given, but the protection scope of the utility model is not limited to the following embodiments.

[0025] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0026] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0027] Example 1

[0028] This utility model addresses the shortcomings of existing quick-connect water connectors, such as the risk of leakage and the outflow of water remaining in the pipe when the water pipe is pulled out. It provides a quick-connect connector, such as... Figure 1 As shown, the quick-connect connector includes:

[0029] The quick-connect valve male end 1 serves as the outlet pipe connector, connecting to the user's end.

[0030] The female end 2 of the quick-connect valve serves as the water inlet pipe connector. It is designed with an air inlet 21 and a water suction inlet 22. When the controllable valve 5 is opened, hot water flows from the female end 2 of the quick-connect valve to the male end 1 of the quick-connect valve.

[0031] Spring valve needle: It is equipped with the first seal 3, which adopts a pressure-type seal and achieves sealing by pressing the sealing ring with a spring.

[0032] Controllable valve 5: Located on the water outlet pipe, it is used to control the water flow. After the quick-connect valve is closed with a two-stage seal, controllable valve 5 opens and water flows through the pipe.

[0033] Specifically, such as Figure 2 As shown, the female end 2 of the quick-connect valve has a plug hole that matches the male end 1 of the quick-connect valve. One end of the plug hole is used to connect to the male end 1 of the quick-connect valve, and the other end is provided with a spring valve needle, which connects to the water inlet pipe. A first seal 3 is provided on the side of the spring valve needle that contacts the female end 2 of the quick-connect valve, and a second seal 4 is provided on the end of the female end 2 of the quick-connect valve near the male end 1. The sealing ring is made of rubber material and has elastic recovery characteristics. The rubber material has good corrosion resistance, can maintain good mechanical strength at room temperature, and has a long service life. The air inlet 21 and water suction port 22, which connect the through hole to the outside, are located between the two sealing structures of the female end 2 of the quick-connect valve.

[0034] like Figure 3 As shown, the quick-connect coupling closes: when the male end 1 of the quick-connect valve reaches the first sealing ring 3 for a second seal, the outer surface of the male end 1 of the quick-connect valve fits against the first sealing ring 3 and the second sealing ring 4.

[0035] The male end 1 of the quick-connect valve moves towards the female end 2 of the quick-connect valve to close. When the male end 1 of the quick-connect valve reaches the second seal 4 to seal and the first seal 3 is separated from the female end 2 of the quick-connect valve, the two quick-connect joints are sealed, the controllable valve 5 is opened, and hot water flows from the female end 2 of the quick-connect valve to the male end 1 of the quick-connect valve.

[0036] like Figure 4 As shown, the quick-connect coupling disengages: both controllable valves 5 are closed, and the male end 1 of the quick-connect valve moves away from the female end 2 of the quick-connect valve to disengage. When the male end 1 of the quick-connect valve disengages from the spring valve needle but not from the second seal 4, the water remaining in the pipe wall of the male / female end of the quick-connect valve can be drawn away through the suction port 22, and then air is introduced through the air inlet 21 to stabilize the pressure and ensure that there is no residual water in the water pipe. When the female end 2 of the quick-connect valve disengages from the second sealing ring 4, the male / female end of the quick-connect valve is completely disengaged.

[0037] Through the above-described configuration, this utility model can achieve the following effects:

[0038] There is no leakage when the parts are joined. When the male end 1 of the quick-connect valve moves to the female end 2 of the quick-connect valve, the two sealing rings fit together completely and seal, and the automatic valve opens to allow water to flow without leakage.

[0039] There is no dripping after disconnection. The automatic valve closes, and the male end 1 of the quick-connect valve moves away from the female end 2 of the quick-connect valve, disengaging from the spring valve needle without disengaging from the second sealing ring. After the water inlet draws away the water pipe and the water remaining in the quick-connect valve, it disengages from the second sealing ring. No water droplets appear on the quick-connect connector or there are no visible water droplets.

[0040] Example 2

[0041] As another embodiment of this utility model, the quick-connect connector can be composed of two or more pairs of matching quick-connect valve male ends 1 and quick-connect valve female ends 2 as described in the above embodiments.

[0042] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
