[0002] With the development of economy and society, humans are manufacturing more and more things. When manufacturing these things, they often discharge waste that pollutes the environment. Waste pollutes the environment, and environmental problems are becoming increasingly serious. Water pollution more or less affects people's daily lives. At present, many families have begun to use water purification equipment to purify their tap water for use.

[0003] Because water purification equipment manufacturers are different, water purifiers of water purification equipment are diverse, and generally most of them are a whole. If a part is damaged, it cannot be used anymore and must be scrapped as a whole. The interfaces of water purification equipment are different, and often they cannot be installed due to the different interfaces. It is necessary to purchase a conversion head. In addition, the water quality entering the water purification equipment often contains micro solid impurities. After long-term use, impurities accumulate in the water purification equipment, affecting the water purification effect.

[0004] Therefore, it is particularly necessary to design a water inlet connector for a water purifier to solve the problems existing in the prior art. Utility Model Content

[0020] Example 1

[0021] A water inlet connector for a water purifier, such as Figure 1-4 As shown, it includes a connecting pipe 1, a fixed pipe 2, a connecting pipe 3, a mounting ring 4, an arc-shaped splint 5 and a rotating ring 6. Several fixed pipes 2 are provided on the upper and lower sides of the connecting pipe 1. The number of the fixed pipes 2 is 3, which can be increased or decreased according to actual needs. A connecting pipe 3 is movably sleeved on one end of the connecting pipe 1, and a mounting ring 4 is provided on the other end of the connecting pipe 1. An arc-shaped splint 5 is installed at the end of the mounting ring 4 away from the connecting pipe 1. The arc-shaped splint 5 facilitates the insertion of the water purifier interface. A rotating ring 6 is threadedly sleeved on the outer side of the arc-shaped splint 5, and the rotating ring 6 clamps the arc-shaped splint 5 to the water purifier interface.

[0022] Install the interface of the water purifier on the fixed pipe 2. Since the fixed pipe 2 has different sizes, they can be matched. If the interface of the water purifier cannot match the fixed pipe 2, insert the interface of the water purifier into the arc-shaped clamping plate 5. The end of the interface of the water purifier contacts the mounting ring 4. Rotate the rotating ring 6. The rotating ring 6 moves along the arc-shaped clamping plate 5 to clamp the arc-shaped clamping plate 5. The arc-shaped clamping plate 5 clamps the interface of the water purifier, thereby installing water purifiers of different sizes.

The outer side of the connecting tube 1 is sleeved with the limit tube 9, and the outer side of the connecting tube 3 is slidably sleeved with the limit tube 9. The outer side of the connecting tube 3 is slidably sleeved with a one-way conical ring 10, and the outer side of the connecting tube 3 is sleeved with a two-way conical ring 11. The end of the two-way conical ring 11 away from the one-way conical ring 10 is slidably provided with a pressure ring 15. Several guide rods 14 are installed on the side of the two-way conical ring 11. The outer side of the guide rod 14 is sleeved with a return spring 16. The guide rod 14 slides through the pressure ring 15, and the end of the guide rod 14 away from the pressure ring 15 is connected to the limit tube 9 to play a connecting role.

[0025] Insert the connecting pipe 3 connected to the tap water into the limiting pipe 9, and the one-way conical ring 10 pushes the blocking block 12 to move to both sides. The blocking block 12 moves to both sides along the limiting pipe 9, and the blocking block 12 moves forward along the two-way conical ring 11 and pushes the pressure ring 15 to move forward. When the pressure ring 15 moves forward, the connecting pipe 3 is sleeved onto the outside of the connecting pipe 1. After the sleeve connection is completed, the connecting pipe 3 is released, and the blocking block 12 is reset under the action of the reset elastic force to clamp the connecting pipe 3. The pressure ring 15 presses the connecting pipe 3 under the reset elastic force of the return spring 16, thereby clamping the connection between the connecting pipe 1 and the connecting pipe 3.

[0026] like Figure 4 As shown, it also includes a blocking block 12 and a return spring 13. The blocking block 12 is symmetrically and slidingly provided on the side of the limiting tube 9.
