Description

Technical Field

[0001] The utility model relates to the technical field of filtering equipment, in particular to a double-buckle filter element. Background Art

[0002] The filter elements of existing industrial vacuum cleaners or household vacuum cleaners are basically composed of an upper cover and a filter element body. Generally, the upper cover is snapped or screwed to the filter element body to facilitate the replacement of the filter element. However, the outer side of the existing filter element is mostly directly exposed. If large particles and hard objects are encountered during the vacuuming process, the filter element is easily damaged. If objects that are easy to entangle, such as hair, are encountered, the difficulty of cleaning the filter element will increase, thereby reducing the service life of the filter element. A small number of filter elements are equipped with a protective net, which not only has a protective function, but also has the function of initial filtration. However, the addition of such a protective net will also increase the cost. Therefore, it is a better choice to set up a protective frame with both functionality and low cost. In order to facilitate the replacement of the filter element, it is also necessary to design an easily disassembled structure.

[0003] Based on this, the applicant proposed a double-buckle filter element to solve the above technical problems. Utility Model Content
