Reverse osmosis filter element and water purifier

Abstract

The invention belongs to the technical field of water purifiers, and particularly relates to a reverse osmosis filter element and a water purifier. The reverse osmosis filter element comprises a filter element body, a filter seat, a filter cartridge, a filter cover and a controller; the filter seat is rotationally connected to the lower end of the filter cartridge; and the filter element body is mounted at the upper end of the filter seat. According to the water purifier disclosed by the invention, through the arrangement of a multi-section electric push rod, the multi-section electric push rod can extrude water in the flow guide pipe to flow out of the filter element, so that bacteria and mineral metal particles blocked by the filter element can be taken away to the surface of the filter layer by the water flowing out by extrusion in a flow guide pipe; a second-section rod of the multi-section electric push rod can push water in a concave block to wash the surface of the filter layer, so that bacteria and mineral metal particles on the surface of the filter layer are separated, on one hand, the bacteria are prevented from corroding the filter layer, and the service life of the filter element is prolonged; and on the other hand, bacteria and mineral metal particles are prevented from being accumulated on the surface of the filter layer to cause blockage of the filter element, so that the filtering rate of the water purifier is improved.

Description

technical field [0001] The invention belongs to the technical field of water purifiers, and in particular relates to a reverse osmosis filter element and a water purifier. Background technique [0002] A water purifier is a drinking water device that filters and sterilizes tap water in depth. It uses different filter materials to improve the safety and quality of direct drinking water. Therefore, once the water purifier is extended to various regions, it greatly improves the quality of drinking water. Drinking water safety and drinking water quality for the whole people. In the prior art, the filter element inside the water purifier is used for a long time, so that bacteria and mineral metal particles accumulate on the surface of the filter element, which causes the blockage of the filter element and affects the water purifier's ability to tap water. Filtration rate, bacteria accumulate on the surface of the filter element and accelerate the corrosion of the filter element, ...

[0002] A water purifier is a drinking water device that filters and sterilizes tap water in depth. It uses different filter materials to improve the safety and quality of direct drinking water. Therefore, once the water purifier is extended to various regions, it greatly improves the quality of drinking water. Drinking water safety and drinking water quality for the whole people. In the prior art, the filter element inside the water purifier is used for a long time, so that bacteria and mineral metal particles accumulate on the surface of the filter element, which causes the blockage of the filter element and affects the water purifier's ability to tap water. Filtration rate, bacteria accumulate on the surface of the filter element and accelerate the corrosion of the filter element, making the water purification effect of the water purifier continuously weakened

[0003] There are also some technical solutions about filter elements and water purifiers in the prior art. For example, a Chinese patent with application number CN201811069521.7 discloses a filter element and a water purifier, including: a central piece; a water inlet pipe; There are several raw water outlet holes on the wall, at least one end of the water inlet pipe forms a raw water inlet, and several water inlet pipes are arranged around the central piece to form a central pipe group; there are several filter chip groups, and the filter chips in the filter chip group are installed on the Between the center piece and the water inlet pipe, and around the center pipe group, there are water inlet flow channels and water production flow channels; the filter chip group also includes a water inlet grid arranged in each water inlet flow channel, and the starting point of the water inlet grid is The side is connected to the outer wall of the water inlet pipe, and the outer wall of the installation is the side wall of the water inlet pipe away from the center piece, so as to achieve the purpose of speeding up the rolling of the filter element; however, this technical solution cannot avoid the long-term use of the filter element inside the water purifier. Bacteria and mineral metal particles accumulate on the surface, which causes blockage of the filter element and affects the filtration rate of tap water by the water purifier. Bacteria accumulate on the surface of the filter element and accelerate the corrosion of the filter element, which makes the water purification effect of the water purifier continue to weaken. The limitations caused by the technical solution
