AI Technical Summary

Problems solved by technology

[0003] Water purifiers include large water purification equipment and small water purifiers. Large water purification equipment has a complex structure, including high-pressure pumps, filters and other auxiliary systems, and is generally suitable for industrial applications. Small water purification equipment has a simple structure and is suitable for household use. Some household water purification equipment is generally fixed on the faucet for water purification. If it is disassembled many times, it is easy to cause poor connection between the water purification equipment and the faucet, and water leakage will affect the use.

[0004] The transfer device is an important connection between the water purifier and the faucet. It is a key role in connecting and disassembling the water purifier and the faucet. The transfer device between the water inlet pipe of the existing water purifier and the faucet is generally formed in one piece One end of the adapter device is connected to the shell with the filter device, and the other end is connected to the faucet. The water purifier is separated from the faucet by disassembling the connection relationship. The existing connection relationship is mostly screw connection. By setting the matching internal and external threads Connect the water inlet pipe of the water purifier with the adapter device to realize the fixed connection between the water purifier and the adapter device. When disassembling, the water inlet pipe of the water purifier will be greatly affected, and the water inlet pipe will be worn during disassembly. After loading and unloading, the tightness of the connection drops sharply, causing water leakage in the pipeline
