Description

Technical Field

[0001] This utility model belongs to the field of pipe joint technology, and more specifically, relates to a leak-proof joint for a vehicle-mounted water dispenser. Background Technology

[0002] In existing water dispensers, the water pipe connector is a crucial component, primarily used for connecting various water storage and supply devices. Current water pipe connectors typically connect two sections of water pipe, one with a female thread and the other with a male thread. A sealing ring is placed inside the female-threaded pipe, and sealing is achieved by compressing the sealing ring when tightened. However, this method often results in irregular deformation of the sealing ring during compression (primarily inward deformation), leading to poor sealing and water leakage. This is one of the main reasons why water dispensers frequently leak.

[0003] For example, a novel leak-proof connector for a water dispenser, as described in patent application number CN98243241.0, features a positioning core tube with a sealing ring inside the female threaded tube. This core tube is integral with the female threaded tube, and its outer diameter is smaller than the inner diameter of the female threaded tube and smaller than the inner diameter of the male threaded tube. The sealing ring is positioned between the positioning core tube and the female threaded tube. This leak-proof connector prevents the sealing ring from undergoing irregular deformation under the relative compression of the male and female threaded tubes, thus effectively sealing the connector. This effectively overcomes the shortcomings of existing technologies and also has advantages such as simple structure, excellent sealing effect, and long service life.

[0004] However, the waterproof performance of the aforementioned new type of leak-proof connector for water dispensers is poor. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a leak-proof connector for vehicle-mounted water dispensers, which improves waterproof performance.

[0006] This utility model discloses a leak-proof connector for a vehicle-mounted water dispenser, comprising a connecting pipe, the upper end of which is fixedly connected to a branch pipe; a valve block is rotatably connected to the inner side of the branch pipe; a handle is fixedly connected to the upper end of the valve block; a liquid channel is also provided on the inner side of the valve block; a pair of liquid channel pipes are fixedly connected to the inner side of the connecting pipe; the inner end of each liquid channel pipe abuts against the lower end of the valve block; and a leak-proof plug is embedded in the lower inner end of the connecting pipe.

[0007] Preferably, a one-way valve is embedded in the liquid channel on the left side.

[0008] Preferably, a one-way valve 2 is embedded inside the liquid channel on the right side.

[0009] Preferably, the connector is made of high-hardness composite resin.

[0010] Preferably, the valve block is made of a polymer composite material.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: (1) By setting up liquid channel pipes, valve blocks, one-way valve one, and one-way valve two, the waterproof performance was improved; (2) By setting a leak-proof plug, a large amount of water can be stored inside the pipe and cannot be drained, thus improving the stability of the connection.

[0013] The following are the labels in the diagram: 10. Connecting pipe; 11. Leak-proof plug; 12. Branch pipe; 13. Handle; 14. Valve block; 15. Check valve one; 16. Check valve two; 17. Liquid passage pipe; 18. Liquid passage. Detailed Implementation

[0014] Specific Implementation Example 1: Please refer to Figure 1-2 A leak-proof connector for a vehicle-mounted water dispenser includes a connecting pipe 10, the upper end of which is fixedly connected to a branch pipe 12; a valve block 14 is rotatably connected to the inner side of the branch pipe 12; a handle 13 is fixedly connected to the upper end of the valve block 14; a liquid channel 18 is formed inside the valve block 14; a pair of liquid channel pipes 17 are fixedly connected to the inner side of the connecting pipe 10; the inner end of each liquid channel pipe 17 abuts against the lower end of the valve block 14; a leak-proof plug 11 is embedded in the lower inner end of the connecting pipe 10; by setting up the liquid channel pipe 17, the valve block 14, the one-way valve 15, and the two-way valve 16, the waterproof performance is improved.

[0015] Please see Figure 2 A one-way valve 15 is embedded in the liquid channel 17 on the left side.

[0016] Please see Figure 2 A one-way valve 16 is embedded inside the liquid channel 17 on the right side.

[0017] Please see Figure 2 The connector 10 is made of high-hardness composite resin.

[0018] Please see Figure 2 The valve block 14 is made of a polymer composite material; by setting the anti-leak plug 11, a large amount of water can be prevented from accumulating inside the pipe 10 and cannot be drained, thus improving the stability of the connection.

[0019] When in operation, turn handle 13 to connect the two liquid channels 17. Then, water flows from the left side to open check valve 15 and flows through the liquid channel 18. Then, water flows from the left side to open check valve 2 16 and flows out from check valve 2 16. As the handle 13 is turned, the upper and lower ends of the liquid channel 18 move out of the inside of the liquid channel tube 17. Even if the water stored in the liquid channel 18 flows out, the water will enter the inside of the connector 10. Finally, the leak-proof plug 11 can be pulled out and discharged from the hole to prevent leakage.
