Filtering cartridge for water purifier

Abstract

The subject of this invention is about water purification function and production of kinds of function water capable of developing characteristics of ceramic, metal and metal oxide through simple structure, effectively preventing generation and replication of mixed bacterium and fungus so as to improve sanitation status, simultaneously seeking for cost reduction. The filter cartridge 1 of purifier encloses the raw water W at one end of the hollow circular cylinder shaped filter material 2 circulating from periphery surface along radius direction, and arranges the outflow port 5a for pure water W' at the other end of the filter material 2. The periphery surface of the filter material 2 is covered with the porous nonwoven cloth 3 added with powdered or granular water treatment agent.

Description

technical field [0001] The present invention relates to a filter cartridge for water purifiers, which is mainly used in water purifiers for purifying tap water in ordinary households, hospitals, factories, offices, etc. It has the function of purifying water and can be manufactured and utilized Functional water with characteristics of ceramics, metals, and metal oxides. Background technique [0002] In recent years, the deterioration of public tap water quality has become a problem. This is because the water quality of the raw water of tap water deteriorates, and a large amount of chlorine as an oxidizing agent and a sterilizing agent must be added in a water purification plant accordingly. [0003] If the water quality itself deteriorates and tap water contains a large amount of chlorine, the taste will deteriorate or a foul smell will be emitted. In addition, it is not suitable for use from the perspective of human health. Therefore, in places such as ordinary family, ho...

[0010] However, since the structure of the aforementioned filter cartridge is that a ceramic filter containing various granular ceramics is arranged in the hollow part of the hollow cylindrical activated carbon filter, for example, when the ceramic filter has antibacterial ceramics, the part in contact with the ceramic filter Tap water can effectively prevent the generation of bacteria and mold, but the tap water in the activated carbon filter that does not reach the ceramic filter has no antibacterial effect

[0011] Therefore, when the water purifier is not in use, after the tap water flowing in the filter cartridge is left for a long time in a stagnant state, bacteria and molds are generated in the activated carbon filter and multiply and proliferate, so the sanitation is in a bad state.

In addition, after being placed in such a state, it will also bring about adverse results of activated carbon deterioration.

[0012] In addition, since the aforementioned filter cartridge is configured with a ceramic filter having approximately the same volume as the hollow part in the hollow part of the hollow cylindrical activated carbon filter, a large amount of ceramics needs to be used, resulting in an increase in cost. The inevitable increase of flow resistance leads to the problem of insufficient flow
