Removable filter structure

This creation is about a removable filter structure.

The conventional detachable filter cartridge structure generally comprises a fixed cover and a filter cartridge. The filter cartridge is detachably mounted on the fixed cover. The fixed cover is inserted into the water inlet pipe, and the water outlet pipe is inserted at the tail end of the filter core. Since the filter element is often installed on the fixed cover in a screw-locking manner, the filter element must be rotated relative to the fixed cover when the filter element is removed, regardless of whether the fixed cover or the filter element is rotated, the pipe is twisted, so the pipe must be first It is very inconvenient to detach and rotate.

Therefore, in order to improve the above problems, the industry has also proposed a new structure. The water outlet pipeline and the waste water pipeline are all disposed on the fixed cover, and the plurality of annular edges of the fixed cover are inserted into the water pipe of the filter core, so that the end of the filter core can be prevented from connecting the pipeline, so that the filter core can be directly rotated. There is no need to remove the tubing.

However, such structures still have a number of disadvantages. First, the ring edge of the fixed cover is inserted into the pipeline of the filter element after the water stop ring is set, but the fixed cover is not a component that is regularly replaced, and the same set of water stop ring is immersed in water for a long time and may accumulate dirt and the like. There are health concerns, and the water stop ring will deteriorate after a long time of use, which will affect the effect of leak prevention; in addition, a filter must be placed outside the filter element to create a gap between the filter element for the waste water to flow through. The outer casing must be replaced with the filter element, thus increasing the cost and price of the filter element.
