Filter element water stop assembly, filter element device and water purifier

Abstract

The invention provides a water-stopping assembly for a filter element, which includes a water-distributing part and a water-retaining part. The water part is provided with a water retaining part docking port; the water retaining part and the water diversion part are connected through a rotating shaft structure, and the water retaining part and the water diversion part control the docking and staggering of the water diversion part docking port and the water retaining part mating port through relative rotation , to realize the connection and disconnection of the water diversion channel and the water retaining channel. Based on the above structure, the water stop component adopts the way of opening and closing water on the side, which simplifies the assembly structure, improves the smoothness of the relative rotation of the water diversion part and the water retaining part, reduces the sense of frustration during rotation, and has better control feel. In addition, the present invention also provides a filter element device and a water purifier comprising the above-mentioned water stop assembly. The filter element device has the advantages of high smoothness of rotation, good operation feel, and simplified assembly structure. The water purifier has the advantages of no water leakage, no Water channeling, easy replacement of filter elements, etc.

Description

technical field [0001] The invention relates to the technical field of filter elements, in particular to a filter element water stop assembly, a filter element device and a water purifier. Background technique [0002] As water purifiers are becoming more and more popular among consumers, consumers have higher and higher requirements for product experience. Among them, the filter element device that automatically seals water when it is disassembled has attracted the most attention from consumers. [0003] Various automatic water sealing filter element devices have appeared in the prior art, mainly including the following technologies: [0004] 1. A water stop valve is installed on the filter element device to realize water connection and water cutoff; [0005] Two, the end of the filter element device is provided with a rotating structure, and the water can be connected and cut off through misalignment; [0006] Third, a rotating structure is set on the filter seat, and th...

AI Technical Summary

Problems solved by technology

[0007] For the above-mentioned first technology, the number of water stop valves will increase with the increase of the water inlet and outlet on the filter element device, which will lead to more and more cumbersome assembly of the filter element device, which has the disadvantages of low production efficiency and high cost

[0008] For the above-mentioned second technology, since the rotating structure at the end of the filter element device is fixed by screws, and the torque of the screws is difficult to control, it is difficult to balance the compression amount of the sealing ring on the rotating structure and the rotating feel, and there are Water Leakage Hazard

[0009] For the above-mentioned third technology, setting a rotating structure on the filter seat will complicate the structure of the filter seat and increase the difficulty of assembly

[0010] In addition to the above-mentioned several defects, the existing filter element device also has deficiencies such as water leakage, incomplete filtration, and complicated disassembly and assembly operations.
