[0002] With the continuous improvement of water quality requirements in modern life, the use of water filters has become increasingly common; among the many types of water filters, water filters with backwashing function are highly favored due to their unique cleaning mechanism; this equipment not only has the sewage discharge function, but also can clean the impurities in the filter by discharging sewage, thereby maintaining its efficient operation and reducing the need for maintenance; the core of the backwashing function lies in its efficient cleaning mechanism; during the filtration process, impurities in the water will gradually accumulate on the filter mesh or filter element, forming blockage and reducing the filtration effect; water filters with backwashing function can start the backwashing program at the appropriate time to flush out the accumulated impurities; during the backwashing process, the equipment will change the direction of the water flow and guide the water that originally entered the filter to the sewage discharge pipe; in this way, the water flow will pass through the filter in the opposite direction, flushing away the impurities on the filter mesh or filter element, And discharged through the pipe; this mechanism can completely clear the blockage of the filter, restore its filtering effect, and enable the filter to continue to work efficiently; in addition to the cleaning mechanism, the water filter with backwashing function also has other advantages; first, it reduces the need for maintenance; traditional filters require regular replacement of filter screens or filter elements, and the introduction of backwashing function can extend the service life of the filter and reduce the frequency of replacement; secondly, the backwashing function can also improve the filtering effect of the filter; by regularly clearing blockages, the filter can maintain a high filtering efficiency and ensure the stability of water quality; when discharging the sewage generated after backwashing the water filter, continuous delivery of clean water is used to achieve the effect of thorough sewage discharge. Due to the influence of the filtering structure inside the water filter, the water flow rate is low, and it is difficult to flush down the sludge on the internal side wall of the water filter, so that the sludge remains inside the water filter and affects the normal operation of the water filter.

[0015] 3. The cleaning brush can be connected to the pressure plate by setting a connecting bracket. By setting the cleaning brush, when the pressure plate is raised or lowered, the fiber track has a spiral structure, and the pressure plate rotates while it is raised or lowered, thereby driving the cleaning brush to rotate, so that the inner side wall of the water storage tank can be scrubbed to prevent sludge from adhering to the inner wall of the water storage tank, resulting in poor filter cleaning effect, thereby resulting in poor filtration effect.
