Water purifier and filter element device with water stop assembly of water purifier

Abstract

The invention provides a filter element device with a water stop assembly. The filter element device comprises a shell, a filter material and the water stop assembly. The filter material is arranged in a filter cavity of the shell to form a filter flow channel; the water stop assembly is mounted in the filter cavity, a water blocking part of the water stop assembly is connected to a water distributor through a rotating shaft structure, the water distributor is provided with a water distributor butt-joint opening, the water blocking part is provided with a water blocking part butt-joint opening, and the water blocking part and the water distributor rotate relatively to control the water distributor butt-joint opening and the water blocking part butt-joint opening to be connected in a butt-joint mode or staggered. Based on the structure, the water stop assembly can prevent residual water in the filter cavity to flow out in the dismounting process of the filter element device; in addition, the mode of side-face water passing or blocking is adopted by the water stop assembly, so that the assembling structure is simplified, smoothness of relative rotation of the water distributor and the water blocking part is improved, the setback feel during rotation is lowered, and good control hand feel is achieved. The invention further provides a water purifier comprising the filter element device. The filter element device has the advantages of non water leakage, non water crossing, convenient filter element replacement and the like.

Description

technical field [0001] The invention relates to the technical field of filter elements, in particular to a water purifier and a filter element device with a water stop assembly. 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 the water can...

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.
