Water purifier and its filter device

Abstract

The invention provides a filter element unit. The filter element unit comprises a water stopping assembly and an automatic water locking assembly, wherein the water stopping assembly can control supply and non-supply of water to a filtering cavity, thereby being able to prevent residual water in the filtering cavity from flowing out in the disassembling process of the filter element unit; the automatic water locking assembly can control supply and non-supply of water between the filter element unit and an external pipe, thereby being able to prevent a water flow in the external pipeline from overflowing in the disassembling process of the filter element unit; thus, a two-way water-sealing structure composed of the water stopping assembly and the automatic water locking assembly completelyeradicates the hidden danger of water leakage, and guarantees that the filter element unit always maintains dry and tidy after disassembled. In addition, the water stopping assembly adopts a manner ofsupply and non-supply of water from a side surface, so an assembly structure is simplified; the smoothness of a water distribution member and a water blocking member during relative rotation is improved; resistance during rotation is reduced; and good hand feeling of operation control is achieved. In addition, the invention also provides a water purifier equipped with the above-mentioned filter element unit. The water purifier has the advantages of no water leakage, no water channeling, conveniently-replaced filter element, etc.

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 thereof. 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 be connected and c...

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.
