[0002] Water purification equipment is a water treatment equipment used to remove impurities, pollutants and harmful substances from water. The main function of water purification equipment is to deeply filter and purify water through physical, chemical or biological methods to provide clean and safe drinking water and water for use. This type of equipment usually includes filters, activated carbon, resin and other materials, which can effectively remove chlorine, heavy metals, bacteria, viruses and other harmful substances in water. According to different filtering principles and functions, there are many types of water purification equipment, such as activated carbon filters, ultrafiltration membrane filters, reverse osmosis membrane filters and water softeners.

[0003] Bag filters are usually used in the primary filters of water purification equipment. Bag filters can filter out most of the larger particles of impurities such as mud and sand. However, there are the following problems in the use of bag filters:

[0004] First, the filter element in the bag filter is often placed with the opening facing upward, and the impurities are uniformly collected in the filter element. However, as a result, the impurities in the filter element accumulate more and more, and the filtering effect becomes worse and worse, resulting in frequent replacement of the filter element and increased consumables costs.

[0005] In addition, in order to ensure the filtering effect of the filter element, the filter element must either be replaced or cleaned. In terms of cleaning, the filter element needs to be taken out of the equipment and cleaned outside the equipment, which is very cumbersome. Utility Model Content
