Environment-friendly household water purifier

Abstract

The invention discloses an environment-friendly household water purifier which comprises a purifier body. The purifier body comprises a purifier shell, a purifier inner cavity and a base; the purifiershell is of a cylindrical structure. An internal filter structure is provided with an ultrafiltration membrane filter layer, a medical stone ceramic ball filter layer, an activated carbon filter layer and a micro-filtration membrane filter layer, the filter direction is from bottom to top, filtering is performed layer by layer, water is injected into a water storage inner cavity from a second water pump and a third water pump, then, the water sequentially passes through the filter layers from bottom to top under the pressure effect of the first water pump and the second water pump and then flows out from a faucet, water flow is more stable, and the filter effect under the anti-gravity effect is better; the water purifier performs back flushing treatment from top to bottom, meanwhile, an air cylinder drives the filter layers to reciprocate under the effect of a spring, impurities and hazardous substances fall into the water storage inner cavity and are discharged from a wastewater discharge pipe, the cleaning effect is better, and the service life of the water purifier is prolonged.

Description

technical field [0001] The invention relates to the field of water purifiers, in particular to an environment-friendly household water purifier. Background technique [0002] Water purifiers are also called water purifiers, water purifiers, water purifiers, and filters. Refers to small filters for household use. Existing household water purifiers are generally divided into gradually tightening water purifiers and self-cleaning water purifiers. Self-cleaning water purifiers are more reasonable in design, eliminating the trouble of manual disassembly and washing, and increasing the practicability of the water purifiers. , and is accepted by the public. [0003] Existing self-cleaning water purifiers use special flushing pipes to backwash the filter element to discharge impurities attached to the filter element, but the effect of backwashing with water flow is not strong. At the same time, existing household water purifiers It is mostly a water outlet, and the water outlet i...

[0003] Existing self-cleaning water purifiers use special flushing pipes to backwash the filter element to discharge impurities attached to the filter element, but the effect of backwashing with water flow is not strong. At the same time, existing household water purifiers It is mostly a water outlet, and the water outlet is connected to an external water dispenser, so that the purified water can be used as drinking water, and the water output of the purifier is small
