Box-type water purifier

Abstract

The invention relates to water treatment industry, in particular to purification aspects of drinking water and discloses a box-type water purifier. The box-type water purifier comprises a filter core communicated with a corresponding water gap of a filtering channel, a frame type rack provided with a front side surface and a rear side surface, and a movable side cover plate, wherein the movable side cover plate is in contact fit with the frame type rack and can move fore and aft along the side face edge of the frame type rack; a water channel switcher is also arranged to be a three-plate structure connected between the filtering channel and a water inlet tube and a water outlet tube of the filter core: a middle plate between an upper plate and a lower plate is a movable plate, and is contacted and matched with the upper plate and the lower plate to form a double sealing switching interface, an outfall communicated with a drainage channel is arranged, a water inlet and a water outlet of the upper plate are connected to the filtering channel; the water inlet and the water outlet of the lower plate are communicated with the water inlet and the water outlet of the filter core; the water inlet and the water outlet of the middle plate are respectively joined and communicated with the corresponding water inlets and water outlets of the upper plate and the lower plate, and the outfall of the middle plate corresponds to the water inlet of the lower plate, and is communicated with the water inlet in a back flushing channel.

Description

technical field [0001] The invention relates to the water treatment industry, and specifically relates to the deep filtration and purification of drinking water. Background technique [0002] At present, the use of water purifiers has been popularized to a certain extent in China. When using water, the water purifier is used to deeply filter the impurities in the water and water pipelines, which better protects the health of users. Due to the high cost of purchasing and using water purifiers, among all types of models, low-priced bare metal with exposed filter elements is the most popular. Yet, along with the popularization of water purifier, their defect and deficiency also gradually exposed in application aspect. After the filter element of the water purifier is used for a period of time, the filter material of the filter element is gradually blocked by impurities and adsorbed on the outer surface of the filter material, resulting in a significant decline in filtration a...

AI Technical Summary

Problems solved by technology

The user is not only inconvenient but also increases the cost of use

And although the filter element can be suspended in the air by the method of fixing the metal base plate of the water purifier support to perforate the wall, it is inconvenient to install and the exposed convex pendant and water purifier open installation will destroy the coordination of facilities, affect Beautiful, reduce the grade of water purifier

In addition, due to the limitation of cabinet space and connecting pipelines, the number of filter elements installed in the water purifier is small, it is difficult to set up functional treatment, and the water flowing out during the replacement of filter elements is not easy to remove, resulting in soaking the cabinet and even damaging the cabinet board

Also, bare metal surfaces are not easy to keep hygienically clean

The above-mentioned defects and deficiencies directly affect the popularization of water treatment machines
