Drinking water filter

Abstract

The invention discloses a drinking water filter including a hand disc (1); the hand disc (1) is connected with a water mixer (3) through a rotating shaft (2); the water mixer (3) is located in a water tank (8) of a water disc (9); one end of the water disc (9) is provided with a water distribution disc (4); distribution holes (5) are distributed at the circumference of the water distribution disc (4); the water distribution disc (4) and a filter layer (6) are connected; the filter layer (6) is connected with a water filter (7) through a water filtering plate (10); the axial outer side of the water filter (7) is connected with a first filter screen (11) and a pressure net (12); the radial direction of the water filter (7) is connected with a second filter screen (13) and an elastic head (15). A bi-directional filtration way is adopted; in the straight direction, the water flow passes relatively fast due to relatively large applied water pressure; but if the water pressure exceeds a certain limit, the water flow can pass through a near second L-shaped guide tube in a filtration manner; therefore, the water pressure is controlled, moreover, the filter screens are protected, and the water quality of the water filter after long-term use is enhanced.

Description

technical field [0001] The invention relates to a household water filter, especially a two-way filtering structure of the water filter. Background technique [0002] At present, household water purifiers are becoming more and more popular. Household water purifiers are equipment for deep processing of tap water by families or groups. Therefore, the purpose of using household water purifiers is mainly to remove visible pollutants in water, such as rust and colloids. Substances, odors and odors, residual chlorine and some disinfection by-products, organic pollutants, heavy metals, etc., and retain mineral elements in water. The structure of the water purifier is different, and the water purification effect is also different. Generally speaking, the structure of the first-stage filter water purifier is simple, and its filtering capacity is limited, so it can only be used for coarse filtration. The filtered water is best heated and boiled for drinking. The composite sintered a...

Problems solved by technology

[0004] Directly connecting the water pipe to the water distribution tank will first cause the water distribution tank to accumulate scale, and then usually rely on the water pressure of the water to press the water flow into the filter layer. Such direct pressure will make the filter layer partially compressed and unstable, reducing filtration. At the same time, when the water pressure is insufficient, local diversion will occur, the utilization rate of the filter layer will be reduced, and a similar fixed "filtering channel" will be formed, which will seriously affect the water quality.

Nuts and bolts are often used at some filter joints of the water filter. In areas with poor water quality, a large amount of scale will be generated in a short period of time, which will cause gravity and water pressure to "penetrate" the bottom filter screen, causing the filter layer to slide down as a whole. Sand and other particles are easy to escape from the filter particles, and the overall extrusion is at the L-shaped pipe, resulting in slow water discharge
