In areas with poor water quality, the speed of the filter screen for accumulating impurities is higher, and the frequency of taking out and cleaning the filter screen is higher. The method of manually removing the filter screen and cleaning also affects the normal use of the water heater circulation system, i.e. the hot water in the water heater cannot be used in the cleaning process. Meanwhile, the method for manually taking out and cleaning the filter screen has high technical level requirement, a user generally cannot operate the method by himself, and professional technicians are required to take out and clean the filter screen, so that time and labor are wasted.

Since the filter cleaning brush 98 of the filter 90 continuously brushes the filter, resistance to water flow is inevitably increased. In addition, the filter screen cleaning brush 98 is inevitably worn during use, the water is polluted by the impurities generated by the wear, and the polluted water may damage the health of the user. As the filter screen cleaning brush 98 is worn, the problem of how to replace the filter screen cleaning brush 98 is still faced, and the use cost is high.
