[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model.

[0017] See Figure 1-2 A filter for easy replacement of filter elements includes a housing 1 and a filter element 2. A fixing ring 3 is provided on the top of the filter element 2. Positioning plates 4 are arranged in annular array outside the fixing ring 3. The upper end face of the housing 1 has a groove 5 arranged in annular array, and the groove 5 cooperates with the positioning plates 4. A guide ring 6 is provided on the outside of the housing 1. A rotating sleeve 7 is provided on the outside of the guide ring 6. An annular groove 8 is provided on the inner wall of the rotating sleeve 7, and the annular groove 8 cooperates with the guide ring 6. Multiple positioning blocks 9 are arranged in annular array inside the rotating sleeve 7. Positioning grooves 10 are provided inside the positioning blocks 9. Positioning strips 11 are provided on the side of the positioning plates 4. When the rotating sleeve 7 rotates, the positioning grooves 10 are fitted onto the positioning strips 11. Specifically, filter element 2 is installed inside housing 1, so that positioning plate 4 is embedded in slot 5 to achieve longitudinal installation positioning of filter element 2; then rotating sleeve 7 is rotated, so that positioning block 9 rotates towards positioning strip 11, and positioning groove 10 is fitted into positioning strip 11 to achieve lateral installation positioning of filter element; through longitudinal and lateral installation positioning, the filter element can be quickly installed. This method facilitates the disassembly and fixing of filter element, thereby ensuring quick replacement of filter element inside the filter, improving the ease of filter element replacement, improving the fixing method of filter and filter element, and ensuring the speed of use of filter and filter element.
