Filtration self-cleaning type clean water sump

Abstract

The invention discloses a filtration self-cleaning type clean water sump. The main application is that: the clean water sump is a facility which filters household tap water into clean water and can reserve the clean water with the same pressure as the tap water, and a filtration device thereof can self-clean and does not need power. A main structure thereof is that: the clean water sump is connected to a main tap water valve, and is connected to a back-flush type three-interface filter through a check valve and a throttle valve; the filtered clean water enters a container which can reserve water and pressure for reservation; at the same time, the clean water sump is connected to a household water consumption pipeline; the sewage of the back-flush cleaning filter is connected to a flushing toiler through a cutoff valve; the self-cleaning of the filter can be finished when the flushing toiler is flushed; and the check valve at the front end of equipment can ensure that the clean water with the pressure can be reserved for families to use when the tap water is cut off, thereby ensuring that the tap water is more convenient and sanitary when people uses the tap water.

Description

Technical field: [0001] The present invention is a facility for filtering tap water into clean water and storing clean water with the same pressure. The filtering device can be self-cleaned without electricity, making it more convenient and hygienic for people to use tap water. Background technique: [0002] Currently known tap water filters are prone to clogging and failure, and need to be disassembled and washed frequently. When tap water is cut off or water is supplied in stages, basins, barrels or pools are commonly used for household water storage, which is neither hygienic nor convenient. There are also advanced tap water treatment devices. Its structure is complex, it needs electricity, and its cost is high, so it is not suitable for ordinary families. Invention content: [0003] In order to overcome the fact that the existing tap water filter is easy to block and fail, and needs to be disassembled and washed frequently, and also for the convenience and sanitation o...
