Background technique

At present, household water purifier filter cleaning equipment is used to clean household water purifier filter cartridges. Water purifiers are also called water purifiers and water purifiers. They are water treatment equipment that deeply filters and purifies water according to the requirements for water use. The water purifiers we usually talk about generally refer to small purifiers used for home use. The function of a water purifier is to filter floating objects, heavy metals, bacteria, viruses, residual chlorine, silt, rust, microorganisms, etc. in the water. After a water purifier is used for a long time, a lot of dirt will accumulate on the filter cartridge, and the filter cartridge of the water purifier needs to be cleaned or replaced regularly.

In the existing cleaning equipment, water flow and a brush are usually used to cooperate with each other to flush the filter element. For example, Chinese patent CN213221289U discloses a filter element cleaning device for environmentally friendly sewage treatment, which includes an equipment box, wherein a flushing area, a scrubbing area and a disinfection area are provided inside the equipment box, and a water pump, a transmission box and a motor are fixedly installed at the bottom of the equipment box, and a spray pipe is fixedly connected to the output end of the water pump; a scrubbing outer cylinder is movably sleeved on the inner side of the scrubbing area, and a scrubbing inner cylinder is movably sleeved on the inner side of the scrubbing outer cylinder. Through the design of the transmission box structure, the rotation of the driving gear is used to make the first driven gear and the second driven gear rotate in the opposite direction, so as to achieve the effect of scrubbing the scrubbing inner cylinder and the scrubbing outer cylinder by rotating in the opposite direction, thereby reducing the use cost, and the structure is simple and easy to clean;

However, in the above-mentioned cleaning equipment, since the filter element is composed of filter materials and various parts installed in combination, during the brushing process, the parts of the filter element may fall off due to the brushing. In particular, metal parts are rusted and broken during the long-term filtration process, and are easily washed away by water during the cleaning process, resulting in loss.
