LEAKAGE-PROOF WATER INTAKE PIPE ASSEMBLY

WIPO Patent Application WO/2024/050976

A1

A leakage-proof water intake pipe assembly, comprising a valve body (1), wherein the outside of the valve body (1) is sleeved with a shell (2), a corrugated pipe (4) being provided in the shell (2); one end of the valve body (1) is sleeved with a second nut (20), and the other end thereof is connected to an inner pipe (5); and the end of the inner pipe (5) facing away from the valve body (1) is connected to a bent pipe (10), one end of the bent pipe (10) being sleeved with a first nut (11). When a valve core assembly (18) moves to the right, a second sealing ring (21) comes into sealing contact with an inclined surface (25) in the valve body (1), so as to cut off the connection of a central pressure-bearing channel (22) and a faucet assembly, thereby cutting off a water flow. In addition, the joints between the leakage-proof water intake pipe assembly and a washing machine, a dishwasher, etc., are provided by using the first nut and the second nut, which can be fitted on the valve body simply by hand. Therefore, the present application has a simple structure, is convenient to operate, has a low manufacturing cost, and can meet the requirement for manufacturing leakage-proof water intake pipe assemblies in batches.
