The filter is composed of a cylinder body, a stainless steel filter screen, a sewage discharge part, a transmission device and an electrical control part. After the water to be treated passes through the filter cartridge of the filter screen, its impurities are blocked. When cleaning is required, as long as the detachable filter cartridge is taken out and reinstalled after treatment, so the use and maintenance are extremely convenient.

[0003] During the replacement process of the filter cartridge, a corresponding device is generally required for assistance. For example, a filter element replacement tool with a Chinese patent publication number of CN216229125U. Its support frame is supported on the filter. By squeezing a first spring through two swing rods, a second boss can be inserted into the filter element. After release, the swing rods reset under the action of the first spring, and the second boss catches the filter element of the filter. The triangular guide block facilitates the second boss to slide into the filter element. Finally, the filter element can be taken out by pulling up the cross bar.

[0004] However, this device only relies on the spring reset to clamp the filter element by the boss, and its strength is insufficient and the reliability is poor. Content of the Utility Model
