Cover sealing device of water purifier provided with upper control module and lower filter container bin

Abstract

The invention relates to the water treatment industry, in particular to drinking water filtration, and discloses a sealing cover device of a water purifier provided with an upper control module and alower filter container bin. The water purifier comprises filter containers, a water passing pipeline, a control part, a lower filter container bin, an upper control module and a loose joint device, the water passing pipeline is connected with a plurality of filter containers and a water passing control part to form a filter channel; the upper control module and the lower filter container bin are connected into a whole through the loose joint device; the water purifier further comprises an inserting plate provided with a plurality of inserting tongues in the same direction and a traction rod, asealing cover device internally provided with an inserting plate interlayer, a coupler provided with a swing rod, a swing shaft, a rear connecting structure and a radial swing rod, a swing handle mechanism provided with an inclined guide structure, and apressing structure matched with the inserting tongues in an inserted mode and arranged on an upper matching component and a lower matching component of the sealing cover device. The swing rod drives the swing shaft and the coupler to swing, the radial swing rod drives the inserting plate to move in the axial direction under the action of the inclined guide rail, the inserting tongue is inserted below the pressing structure, and the sealing cover device is connected with components matched with the sealing cover device vertically in an inserted mode.

Description

[0001] Title of prior application: Capping device for water purifier with upper control module and lower gallbladder chamber [0002] Prior application number: 201910381928.1 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 of the water purifier, the filter gall needs to be replaced after being used for a period of time. However, with the popularization of water purifiers, their defects and deficiencies in application are gradually exposed: most of the middle and low-priced water purifiers use an open liner configuration bare metal model. The shell with the built-in liner is hoisted under the machine base. Although the shell can be reused, which reduces the cost of replacing the filter tube by 10-20% for consumers, it also produces a single product structure, liner replacement and filter cavity. Difficulty cleaning...

AI Technical Summary

Problems solved by technology

Because the environment where the water purifier is placed is usually relatively poor, the leaked water flow rate is too fast and difficult to remove during the replacement of the filter cartridge, which not only causes inconvenient operation, but also causes the cabinet to be soaked and even damaged.

In view of the fact that the replacement of the filter is always accompanied by the whole process of using the water purifier, the related problems caused by the replacement of the filter and the cleaning of the filter channel will often appear repeatedly

In addition, after the water purifier has been used for a long time, the fouling of the filter cartridge and the inner wall of the pipeline is very serious, and the water purification treatment environment of the water purifier is getting worse and worse.

Especially because the cleaning of the inner cavity of the U-shaped open filter cartridge, the discharge of sewage containing a large amount of impurities, and the extraction of the built-in filter gall are not solved, so that the model with the lower base is rarely used.

On the other hand, the filter replacement and cleaning and maintenance of the water purifier require on-site service by professionals. Users mentioned machine cleaning problems

As a result, the vast majority of users only know to replace the filter, but very few people know to clean the machine regularly

Above-mentioned defect and deficiency cause water purifier to be difficult to obtain wider popularization
