Fast-detachable cleanable filter element

Abstract

The invention relates to the field of water purifier filter elements, in particular to a fast-detachable cleanable filter element. The fast-detachable cleanable filter element comprises an outer cylinder and a filter module which is arranged in the outer cylinder, wherein the outer cylinder comprises a cylinder body and a cylinder cover which can be detachably connected to the cylinder body, a groove is formed in the lower part of the cylinder body, a sealing ring is arranged on the outer side of the bottom end of the cylinder body, the cylinder cover comprises a clamping sleeve and a locking sleeve which sleeves the clamping sleeve and can be moved up and down, rolling balls which are matched with the groove are arranged on the clamping sleeve, and can offset in the clamping sleeve in the radial direction, an elastic part is arranged between the locking sleeve and the clamping sleeve, and the locking sleeve can inwards push the rolling balls through the elastic part and facilitates the rolling balls to be tightly clamped with the groove. The outer cylinder of the filter element is detachable, and the filter module can be detached quickly while water sealing is ensured, so that the filter module is quickly cleaned and replaced.

Description

technical field [0001] The invention relates to the field of filter elements of water purifiers, in particular to a quick-release cleanable filter element. Background technique [0002] The filter elements used in existing water purifiers are composed of an outer cylinder and a filter assembly arranged in the outer cylinder. After the filter assembly is placed in the outer cylinder, the outer cylinder is integrally formed by a thermoplastic process, and the filter element is made into a disposable product to achieve good quality. Water-tight effect. [0003] Existing filter components generally use one or more combinations of filter material, activated carbon and PP cotton. In addition, in order to obtain high-quality water, the filter assembly generally includes a filter material layer, an activated carbon layer and a PP cotton layer arranged in sequence from the inside to the outside. [0004] Such a filter component, on the one hand, because the life of the PP cotton fi...

AI Technical Summary

Problems solved by technology

[0004] Such a filter component, on the one hand, because the life of the PP cotton filter element is 6 months, and the life of the activated carbon filter element is 12 months, because the two materials are replaced at the time when they first reach their service life under normal circumstances, because the filter element is integrated. The user can only replace the new filter element, so the life of the original activated carbon is shortened by 6 months from 12 months; on the other hand, the outer cylinder is made of PC, and its service life is more than 1 year. The design of the integrated filter element It also virtually reduces the service life of the outer cylinder
