Problems solved by technology

The disadvantage of increasing the amount of filter material to prolong the service life is that once the filter element is polluted during use, such as bacterial growth or filter element clogging, the entire filter element must be replaced, resulting in material waste and increased use costs.

Abstract

The invention discloses a multi-interlayer filter element which comprises a filter element shell, a filter element main body and a piston, wherein the filter element main body is arranged in the filter element shell; a water flow channel is formed in the filter element main body; one end of the water flow channel is a water inlet end, and the other end of the water flow channel is a water outlet end; the filter element main body consists of multiple filter element interlayers which are independent from one another; each filter element interlayer is provided with a water inlet hole and a water outlet hole which are connected with the water flow channel; the piston is arranged in the water flow channel, is in seal fit with the water flow channel and moves under the action of water pressure in the water flow channel; and each filter element interlayer is sequentially opened and is connected to the water channel so as to filter the water. According to the integrated packaging mode, the materials are saved, the service cycle is long, and the replacement frequency is reduced.

Description

technical field [0001] The invention relates to the technical field of water filtration, in particular to a multi-layer filter element. Background technique [0002] In the prior art, the water purifier adopts multi-stage filtration or single-stage filtration. When multi-stage filtering, [0003] Because the service life of each filter element is different, the replacement cycle of the filter element is inconsistent, and the filter element needs to be replaced frequently, which is more troublesome to use; in the case of single-stage filtration, due to the different water quality and water usage habits in different regions, when the filter element is polluted and bacteria breed, it is impossible to accurately grasp the timing of filter element replacement. [0004] In order to increase the service life of filter elements such as activated carbon, the amount of filter material is usually increased. The disadvantage of increasing the amount of filter material to prolong the s...
