[0015] 1. This utility model provides a multi-layer pressure filter. Through the setting of the built-in filtration mechanism, the inner wall of the filter box and the outer wall of the insert fit together. The filter connector is used to connect the filter cylinder and the insert. There are two sets of filter cylinders. The filter connector connects the two sets of filter cylinders and the insert from the inside to the outside. This structure allows the water input by the external pump pipe to be directly input into the insert and then filtered through the two layers of filter cylinders in sequence. The filtered water overflows from the center of the filter cylinder and is output outward through the outlet pipe. The built-in filtration mechanism in this structure is pressed and sealed by the pressure test cover mechanism. The pressure filtration from bottom to top makes large impurities filtered to the bottom layer. Moreover, the filter connector is a cylindrical filtration structure with a large filtration area and high efficiency, which solves the problem of small filtration area and low efficiency caused by the flat laying of the filter screen in existing water filters.

[0016] 2.

The external pump pipe is set on one side of the cleaning pipe. The cleaning pipe is set vertically, which makes it easy to turn on the switch after filtration. The water remaining in the filter box can self-clean the filter connection parts to avoid clogging. This solves the problem that existing water filters complete filtration from top to bottom, and the filter screen may accumulate impurities, causing clogging and making it difficult to clean.
