Dual water supply water purifierwith combined filter elements

Abstract

The invention discloses a dual water supply water purifier with combined filter elements. The water purifier comprises first-stage to fourth-stage filter cylinders, cylinder covers, first-stage to seventh-stage filter elements, a water inlet, first-stage to third-stage water outlets, a communicating pipe and a wastewater outlet; the filter cylinders are cylindrical shells for accommodating the filter elements, and a plurality of J-shaped clamping grooves are uniformly formed along the outer circles of the openings of the filter cyliners; the cylinder covers are devices for closing or opening the filter cylinders, a plurality of clamping convex blocks are uniformly arranged on the cylinder covers along the outer circles, and the clamping convex blocks are clamped in the J-shaped clamping grooves of the filter cylinders; the first-stage to seven-stage filter elements are seven water treatment devices, and the first-stage, second-stage, third-stage, fourth-stage, fifth-stage and sixth-stage filter elements respectively form the combined filter elements; the first-stage to third-stage water outlets are water outlets for supplying water according to different quality; the communicating pipe is the communicating pipeline between the filter cylinders; and the wastewater outlet is a nanofiltration membrane output wastewater outlet. The water purifier has the beneficial effects that water is supplied according to different qualities, one cylinder has multiple elements, the structure is simple, the cylinder cover is easy to open and seal, and the filter elements are convenient to replace, disassemble and wash.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to a combined filter element quality-separated water supply water purifier for civil drinking water treatment. Background technique [0002] Daily water often contains impurities such as rust, sand mud, colloid, residual chlorine, pesticides, bacteria, germs, toxins, heavy metals and other impurities. Water, on-demand water supply is necessary. [0003] At present, all the water purifiers on the market mainly have the following shortcomings: [0004] (1) The water quality classification is unclear, that is, the classification of drinking water and domestic water is unclear, and there is a misunderstanding of using purified water for drinking water but ordinary water for cooking; [0005] (2) There is a purification function, but no sterilization function, or the sterilization function is unreliable, causing secondary pollution; [0006] (3) The structure of the whole machine is com...

AI Technical Summary

Problems solved by technology

[0004] (1) The classification of water quality is unclear, that is, the classification of drinking water and domestic water is unclear, and there is a misunderstanding of using purified water for drinking water and ordinary water for cooking;

[0005] (2) It has purification function but no sterilization function, or the sterilization function is unreliable, causing secondary pollution;

[0006] (3) The structure of the whole machine is complicated, it is inconvenient to replace or clean the filter element, and it is difficult for non-professionals to operate;

[0007] (4) Part of the filter element and the filter cartridge are in an integrated structure, and the manufacturing cost increases, and the replacement filter element and the filter cartridge are replaced together, resulting in unnecessary waste;

[0008] (5) The filter cartridge and the cartridge cover are in a threaded locking structure, which is strong in tightness and difficult to operate;

[0009] (6) There is no automatic flushing function of the primary filter element, and the service life of the filter element is short
