A sealing gasket is connected to the top of the bottom box, and a connecting piece is fixedly connected to the middle of the surface of the connecting plate. A filter element and an activated carbon mesh bag are provided on the inner side of the connecting plate. The air purification device that is easy to replace filter elements is provided with a connecting piece, fixing bolts and filter elements symmetrically distributed on the upper and lower sides of the activated carbon mesh bag. The device can improve the air filtering effect of the device by using a double-layer filter element in combination with the activated carbon mesh bag. At the same time, the filter element and the activated carbon mesh bag are mounted on the connecting plate through the connecting piece and fixing bolts, which facilitates the replacement of the filter element and the activated carbon mesh bag.

[0004] When the above-mentioned air purification device with convenient filter element replacement is used, the filter element containing a large amount of dust needs to be disassembled. During the disassembly process, the dust on the filter element is easily knocked off at the moment when the filter element is detached from the clamping structure, causing dust to fly in the replacement structure cavity. The filter structure needs to be cleaned, which increases the workload of the replacement work. Therefore, in order to solve the above problem, an air purification device with convenient filter element replacement is proposed. Utility Model Content
