Leak-proof safety pipe for water purifier

Abstract

The invention relates to a leak-proof safety pipe for a water purifier. The leak-proof safety pipe for the water purifier is mounted between the water purifier and a water inlet pipe. The leak-proof safety pipe for the water purifier comprises pipe ends and a pipe body, wherein seal threads are arranged at the pipe ends; a safety cavity is formed in the pipe body, the lower bottom of the safety cavity is made of a piston plate, and the piston plate can slide in a reciprocating mode along the inner wall of the safety cavity; an adjustment plate is arranged at the upper end of the safety cavity, and an adjustment knob which penetrates through the pipe body is mounted on the upper portion of the adjustment plate; a pressure-limiting valve is arranged on the side wall of the safety cavity; a hollow blocking valve is arranged on the inner pipe wall of the pipe body and communicates with the pressure-limiting valve through a guide pipe; and in the natural state, the blocking valve is closely attached to the inner pipe wall of the pipe body. By adoption of the structure, pipe explosions caused by an excessively-high water pressure can be effectively prevented, and the using stability and safety of the water purifier are improved.

Description

technical field [0001] The invention relates to a water purifier accessory, in particular to a leak-proof fuse. Background technique [0002] With the improvement of people's living standards, water purifiers have entered thousands of households, contributing to the drinking water health of the general public; water purifiers currently on the market include cartridge water purifiers and RO membrane reverse osmosis pure water machines two kinds. Both of these machines are directly connected to tap water. Due to the unstable tap water pressure, excessive pressure will cause the filter cartridge in the machine to leak, and the connecting pipe is easy to fall off and leak water; especially the increase of RO membrane reverse osmosis pure water machine. The pressure pump usually has to reach a pressure of 7kg to make the RO membrane extrude pure water, but in a state of high pressure, it is easy to cause the low pressure switch to fail, and the joints are not well sealed, and th...

Problems solved by technology

Both of these machines are directly connected to tap water. Due to the unstable tap water pressure, excessive pressure will cause leakage of the filter cartridge in the machine, and the connecting pipe is easy to fall off and leak water; especially the increase of the RO membrane reverse osmosis pure water machine. The pressure pump usually needs to reach a pressure of 7kg to make the RO membrane extrude pure water, but in the state of high pressure, it is easy to cause the low pressure switch to fail, and the joints are not well sealed, and these reasons will cause water leakage.

When there is water leakage in the machine, if the water source is not found and turned off immediately, it will cause property loss and waste of water resources.

[0003] For these reasons, it seems impossible to completely eliminate the leakage of water purifiers in theory, or if it must be done, the manufacturing cost will rise to an unaffordable level for users
