Description

Technical Field

[0001] The utility model relates to the technical field of filter elements, in particular to a swimming pool filter element with a retractable handle. Background Art

[0002] In the daily work of swimming pool maintenance and care, the swimming pool filter is a key water purification component. Its regular replacement and cleaning are essential to maintaining the clarity and hygiene of the swimming pool water. However, in actual operation, the threaded connection between the swimming pool filter and the filter often results in an overtight connection. The overtight threaded connection requires the staff to use greater force to unscrew it, which increases labor intensity. In addition, the swimming pool filtration system is usually installed in a limited space, and the equipment is closely arranged. When installing and laying out the equipment, there is usually operating space for removing the filter element. However, sometimes the original space reserved for arm operation will be blocked by other equipment, resulting in limited arm movement or tricky angles for reaching out to operate, making disassembly difficult. For this reason, a swimming pool filter with a retractable handle is proposed. Utility Model Content
