[0002] At present, due to the advancement of technology, people's living facilities are also constantly improving. Some water industry equipment that directly uses tap water as a water source continues to appear, such as water heaters, automatic water dispensers, etc. Due to various reasons, most tap water circulation pipes have more or less some impurities or foreign matter. In order to avoid impurities or foreign matter entering such equipment, people will use water filtration equipment to filter the water in advance.

[0003] The existing water filtering equipment includes a shell and a filter screen. The shell is provided with a water inlet and a water outlet. The filter screen is arranged in the shell, and the filter screen is connected to the inner wall of the shell. A cleaning port is opened on one side of the shell. The shell is hinged with a closed door at the cleaning port. During the process of water filtering by the water filtering equipment, water enters the shell from the water inlet. After the filter screen finishes filtering the water, the water flows out of the shell from the water outlet. At the same time, impurities in the water flow to the filter screen. After the water filtering equipment has been used for a period of time, in order to avoid blockage at the filter screen, water is stopped from being transported into the shell. The staff opens the closed door and cleans the impurities on the filter screen from the cleaning port.

[0004] With regard to the above-mentioned related technologies, when cleaning impurities, it is inconvenient for workers to operate due to the narrow space inside the shell, thus resulting in the defect of inconvenience in cleaning impurities. Utility Model Content
