Description

Technical Field

[0001] The utility model relates to the technical field of filter screens, in particular to an assembled multi-layer filter screen. Background Art

[0002] The range of filters is quite wide, and the filters usually refer to air filters. According to the different materials, filters are divided into four types: synthetic fiber filters, non-woven filters, glass fiber filters, and activated carbon filters. Filters can also be divided into primary filters and medium-efficiency filters according to the different filtering efficiencies. In order to better ensure the filtering effect of multi-layer filters, an assembled multi-layer filter is required.

[0003] For example, after searching the Chinese patent announcement No. CN213159896U, an assembled multi-layer filter screen is disclosed, in which the positioning frame is inserted into the mounting frame and is against the filter screen, and the second positioning spring is randomly deformed under force to generate elastic force. The second positioning spring pushes the mounting frame and the filter screen through the positioning frame, and the multi-layer filter screen remains tight under the squeezing of the mounting frame and the positioning frame, avoiding the problem that most existing multi-layer filter screen equipment cannot ensure the close fit between the multi-layer filter screens during use, which is easy to produce gaps, affecting the filtering effect of the equipment, and is not conducive to the popularization of the equipment.

[0004] However, the above device has certain shortcomings in actual use. Although it can avoid the problem that most existing multi-layer filter devices cannot ensure that the multi-layer filter screens fit tightly during use, gaps are easily generated, affecting the filtering effect of the equipment. However, when used for a long time, some impurities will adhere to the surface of the filter screen, thereby making the filtering effect of the multi-layer filter screen poor. Utility Model Content
