Cylindrical filtering water purifier

Abstract

The invention relates to a cylindrical filtering water purifier, which comprises a cylindrical shell, a filtering unit, a water inlet pipe, a water outlet pipe and a water purifying pipe; the filtering unit comprises a filtering cavity, a filtering core is arranged in the filtering cavity, and the filtering core comprises a rotating shaft and a filtering cylinder; the filter cartridge can freely rotate relative to the rotating shaft; the axis of the cylinder shell and the rotating shaft are in different planes; the filter unit further comprises a cleaning strip; the filter unit formed by the cleaning strip, the filter element and the filter cavity is seamlessly jointed with the inner wall of the cylinder shell; the drainage pipes and the filtering units are arranged in a one-to-one matching manner. From the water outlet direction, the connecting port of each water discharging pipe and the barrel shell is arranged in front of the filtering unit. The filtering assembly in the water purifier is novel in structure and unique in principle, has a certain self-cleaning function, and can keep the water purification effect and the water outlet speed of the water purifier for a long time, sothat the service life of the filtering assembly in the water purifier is effectively prolonged.

Description

technical field [0001] The invention relates to the field of water purification, in particular to a water purifier. Background technique [0002] With the development of industry, the water resources used by people have been seriously polluted, and the quality of drinking water has dropped sharply; in order to ensure the health of water, many residents have installed water purifiers for their homes; filter membranes are one of the core components of water purifiers. Among the filtration membranes currently on the market, the reverse osmosis membrane is one of the membrane elements that can filter smaller particles. Its filtration size can even reach 0.0001 microns, which can effectively filter out bacteria, microorganisms and other harmful substances in the water to ensure the purity of water quality. ;Because the membrane element is a disposable element, the membrane element is relatively new at the beginning of installation and can efficiently filter harmful impurities in ...

[0002] With the development of industry, the water resources used by people have been seriously polluted, and the quality of drinking water has dropped sharply; in order to ensure the health of water, many residents have installed water purifiers for their homes; filter membranes are one of the core components of water purifiers. Among the filtration membranes currently on the market, the reverse osmosis membrane is one of the membrane elements that can filter smaller particles. Its filtration size can even reach 0.0001 microns, which can effectively filter out bacteria, microorganisms and other harmful substances in the water to ensure the purity of water quality. ;Because the membrane element is a disposable element, the membrane element is relatively new at the beginning of installation, and can efficiently filter harmful impurities in water, but after a period of use, a large amount of dust is attached to the membrane element, and the filtration effect of the membrane element becomes poor at this time. The required water pressure increases, and at this time the water outlet speed and water purification effect of the water purifier will be greatly reduced; in addition, most of the current reverse osmosis membrane elements are spiral wound. The porous support material needs a long stroke to collect to the center pipe, the water outlet speed is slow, and the water pressure required is relatively high, so the booster pump needs to work at high power and generate relatively loud noise; another hollow fiber membrane element is Production is difficult and the price is too high
