Description

Technical Field

[0001] This utility model relates to the field of automatic filter cleaning technology, specifically a central water purification device with active sewage discharge. Background Technology

[0002] Most human diseases are related to drinking water, such as bacteria, soluble calcium and magnesium compounds, and heavy metals. To ensure people's safety, many households and communities install water purifiers to filter water before drinking. However, prolonged filtration can cause a large amount of contaminants to accumulate on the surface of the filter cartridge, requiring timely cleaning; otherwise, bacteria will grow, affecting the safety of drinking water. However, existing central water purification systems are relatively complex in structure. Removing and replacing the filter cartridge requires a prolonged water outage, and maintenance is needed periodically, resulting in high maintenance costs. Furthermore, advance appointments with maintenance personnel are required, making widespread adoption impractical. Utility Model Content

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: When the filter element inside the filter cartridge needs to be cleaned, the electromagnet is energized, the magnet head moves downward, and the sealing block and guide cover fit tightly together, thereby guiding the sewage to the drain outlet. The magnet head continues to move downward, causing the filter element to pass through the blocking ring. The surface of the filter element is squeezed and scraped by the blocking ring, cleaning the surface of the filter element. The electromagnetic pole changes, causing the filter element to move upward again. In the back-and-forth process, the surface of the filter element can be automatically cleaned. There is no need for special maintenance personnel to replace the filter element. The cleaning interval can be controlled according to actual needs. Maintenance is simple and convenient, and the cost is low. Attached Figure Description
