Water purifier with upper control bin and lower filtering inner container bin and supporting filtering inner containers

Abstract

The invention relates to the water treatment industry, in particular to drinking water filtration, and discloses a water purifier with an upper control bin and a lower filtering inner container bin and supporting filtering inner containers. The water purifier comprises the filtering inner containers and filtering inner container fastening devices. A water passing pipeline connected with the filtering inner containers in series is connected with a water inlet and a water outlet of a base to form a filtering channel. The water purifier further comprises a U-shaped filtering inner container cavity containing the filtering inner containers, a big bin cover, a small bin cover, a big cover fastening device and a small cover fastening device. The big bin cover is either of a movable cover structure or of a turnover cover structure, and is connected with an upper port of the U-shaped filtering inner container cavity containing the filtering inner containers through the big cover fastening device in an up-and-down matched mode to form the lower filtering inner container bin. The small bin cover is either of a movable cover structure or of a turnover cover structure, and is integrally connected with the big bin cover through the small cover fastening device to form the upper control bin. The filtering inner containers with limit structures are arranged in the U-shaped filtering inner container cavity, wherein the filtering inner containers are separated from the base after the big bin cover is opened and the filtering inner container fastening devices are disengaged; or the filtering inner containers are arranged in a filtering inner container hole rack of the big bin cover, wherein the filtering inner containers are separated from the base after the small bin cover is opened and the filtering inner container fastening devices are disengaged.

Description

[0001] Prior application: water purifier with upper control chamber and lower filter chamber and supporting filter [0002] Prior application number: 201410820125.9 technical field [0003] The invention relates to the water treatment industry, and specifically relates to the deep filtration and purification of drinking water. Background technique [0004] As a consumable for the water purifier, the filter gall needs to be replaced after a period of use. However, with the promotion of water purifiers, their defects and deficiencies in application are gradually exposed: most of the medium and low-priced water purifiers use an open liner configuration bare metal model. The machine structure in which the filter housing with built-in liner is hoisted under the machine base, although the filter housing can be reused, correspondingly reduces the cost of replacing the filter tube by 10-20% for consumers, but also correspondingly produces a single product structure, liner replaceme...
