Description

Technical Field

[0001] The present application belongs to the technical field of water treatment, and specifically relates to a filter. Background Art

[0002] As people's living standards improve, their pursuit of quality of life also increases. For example, more and more consumers begin to pay attention to the health of water quality. Among them, related technologies usually use filter elements to optimize water quality.

[0003] For example, in the brominated hydantoin resin filter element with patent publication number CN218833843U, water flows in from the inlet at one end of the filter cartridge, flows axially through the entire filter cartridge, and is filtered and sterilized by the brominated hydantoin resin particles filled axially in the filter cartridge, and then flows out through the outlet, completing the filtration and sterilization of the water. Another example is a water sterilization system with patent publication number CN214495951U, in which unsterilized water flows out from the water inlet pipe, water inlet trough, water inlet, top water permeable membrane, sterilization filter element, bottom water permeable membrane, water outlet, water outlet trough and water outlet pipe in sequence, and the water flows through the entire filter element from top to bottom, blends with the brominated hydantoin resin particles filled from top to bottom in the filter element, and sterilizes and filters the water.

[0004] The principle of sterilizing water by passing through the filter element of brominated hydantoin resin particles is as follows: when water flows through the filter element filled with brominated hydantoin resin particles, brominated hydantoin resin, as a water sterilizing material, can turn water into ultra-low concentration hypobromous acid water, and hypobromous acid accompanies water all the way, killing bacteria and viruses, and completing sterilization. In the above two patents, when water is sterilized, it must flow through the brominated hydantoin resin particles filled along the length direction of the filter element, resulting in a high concentration of hypobromous acid in the water flowing out of the water outlet, affecting the drinking taste, and when it is needed again after being unused for a long time, in order to ensure drinking safety, it is necessary to open the outlet to remove the water stored in the filter element that has reacted with the brominated hydantoin resin particles for a long time, and then the water flowing out can be used or drunk, resulting in a waste of water resources and brominated hydantoin resin particles. Utility Model Content

[0005] The purpose of the present application is to provide a filter that utilizes the slow-release principle to sterilize water, which will not cause a high concentration of hypobromous acid in the outflowing water and will not affect the drinking taste. Moreover, when the filter in the present application is not used for a long time and is reused, it is only necessary to open the water outlet to allow the water in the filter element housing that is higher than the water outlet to flow out, thereby reducing the waste of water resources and brominated hydantoin resin particles.
