Description

Technical Field

[0001] This utility model relates to the field of kitchen and bathroom technology, and in particular to a filter and a spring-loaded drain. Background Technology

[0002] Currently, most drain outlets on the market are equipped with cylindrical filter screens. However, these filter screens are mostly one-piece structures. Although they are easy to manufacture and have low production costs, they are difficult to clean during use. This is especially true for some deeper filter screens with smaller diameters, where it is difficult to clean the hair and other debris filtered inside. Often, it is necessary to turn the screen upside down and rinse it with water for a long time to clean it. However, such a cleaning process can easily cause discomfort to the user. Therefore, this utility model provides a filter screen that is easy to clean and can solve the above-mentioned technical problems. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model proposes a filter structure that is easy to clean.

[0004] In a first aspect, a filter screen is provided, comprising a filter screen body, a filter screen base, and a lifting component, wherein...

[0005] The filter screen body is tubular, with one end being the water inlet and the other end being the water outlet.

[0006] The outer diameter of the filter base is smaller than the inner diameter of the filter body, and it is installed through the water inlet end of the filter body. An easy-to-disassemble structure is provided between the filter base and the inner wall of the water outlet end, allowing the filter base to be installed inside the filter body via this structure, and also making it easy to disassemble. Both the filter body and the filter base have filter holes, enabling the filter to both drain water and perform filtration.

[0007] One end of the lifting component is assembled with the filter base, and the lifting component forms a handle for the filter body, allowing the user to assemble or disassemble and remove the filter base during cleaning.

[0008] The filter screen provided by this utility model has a screen body that can be disassembled into a screen body and a screen base. In use, they are assembled together by the easy-to-disassemble structure to form a water-filtering screen. When cleaning, the lifting part is used as a handle, and the screen base is removed from the screen body by the easy-to-disassemble structure. At the same time as removing the screen base, the accumulated debris inside the screen can also be removed. Even if the screen is deep and has a small diameter, the debris can be easily cleaned out. In addition, the screen body and screen base can be easily washed separately after disassembly. It can be seen that the filter screen provided by this utility model provides great convenience for cleaning.

[0009] Preferably, the lifting member is rod-shaped, and the filter base and the lifting member are fixedly assembled or integrally formed, which has a simple structure, is easy to manufacture, and is not easily damaged during use.
