However, due to the pollution of the natural environment and the impact of human activities, many water sources contain various impurities, such as silt, rust, microorganisms, heavy metals, etc. These impurities not only affect the taste and appearance of water, but also pose a potential threat to human health. Therefore, using a filtration device to purify water and remove harmful substances is essential to ensure the safety of people's drinking water.
[0003] During the long-term use of traditional filtering devices, the granular impurities such as sand and rust in the water will accumulate on the filter element, which will cause the filter element to be blocked, seriously affecting the filtering effect and water production of water quality. When the filter element is blocked, if it is not flushed, it will not only breed bacteria, but also affect its filtering effect. In the existing technology, the staff needs to manually disassemble and clean it, which not only increases the workload of the users, but also affects the continuity and stability of the water treatment system. Therefore, we have made improvements to this and proposed a backwashing structure for the filter. Utility Model Content
