Description

Technical Field

[0001] The utility model relates to the field of filters, in particular to a filter with a filter element that is easy to clean. Background Art

[0002] The development of filter elements can be traced back to ancient times. Initially, people used natural materials such as stone, sand and charcoal to filter water. The filter is a device used to filter liquid media. It mainly uses filter materials to block and filter impurities in the fluid, making the liquid flowing through the filter cleaner and purer. It is usually composed of a cylinder, a channel tube and a filter material. Clean liquid is obtained by filtering the liquid.

[0003] Existing filters usually use long-cylinder filter elements to filter impurities, so as to store more impurities, increase the service life, and extend the cleaning cycle. Some filters also use multiple sets of bolts to fix the top cover and the tank body to maintain a seal. After the outer wall of the bolt is clamped into the external groove of the top cover, the pressure ring or nut is rotated to squeeze the top cover so that the top cover is close to the tank body to achieve a sealing effect.

[0004] On the one hand, the existing long-cylinder filter element is time-consuming and laborious to clean due to its long and narrow internal space, and is not convenient for manual cleaning at home. On the other hand, the operation of the existing bolt-fixed top cover seal is cumbersome, and the nut needs to be repeatedly turned to install or remove the top cover, which is not convenient for disassembly and cleaning of the filter element. Therefore, a filter with an easy-to-clean filter element is proposed to solve the above problems. Utility Model Content

A limiting groove 9 is provided at the bottom end of the outer wall of the filter element 17. The limiting groove 9 is provided with a shape corresponding to the limiting block 20, which is used to clamp the limiting component to fix the filter element 2 12 and connect it to the filter element 1 7. The inner wall of the slide groove 8 is slidably connected with the slider 10. The slider 10 is set as a T-shaped block, which is used to keep the connecting plate 11 vertical under the influence of external force to avoid the displacement of the filter element 2 12, resulting in the inability to effectively filter impurities. The outer wall of the outer side of the slider 10 is fixedly connected with a connecting plate 11, and a limiting component is set at the bottom end of the outer wall of the connecting plate 11.
