[0020] Example

[0021] In the current technology, the filter structure of air purifiers used in the market is relatively simple. When disassembling and assembling, it is necessary to pull the pull head on the outside of the filter element, which leads to the problem of inconvenience in disassembly.

[0022] Please see Figure 1-5 This utility model provides a technical solution: a convenient air purifier filter structure, including an air purifier body 1, an air purifier body 1 including a cover plate 2, a filter element body 3 installed inside the air purifier body 1, filter cotton 4 fixedly arranged on the outer side of the filter element body 3, and annular plates 5 fitted on the outer sides of both ends of the filter element body 3. Rubber rings 6 are embedded in the inner wall of the annular plates 5, and a connecting plate 7 is fixedly arranged on one side of the annular plates 5. A connecting structure is provided between the upper and lower connecting plates 7. In use, the two annular plates 5 are fitted on both ends of the filter element body 3. The rubber rings 6 inside the annular plates 5 will increase the friction between the annular plates 5 and the filter element body 3. The connecting structure is provided on the outer side of the two annular plates 5 through the connecting plate 7. The filter element body 3 is installed inside the air purifier body 1 through the connecting structure. At the same time, when it is necessary to replace it, the cover plate 2 is opened, and the filter element body 3 is pulled out from the air purifier body 1 through the connecting structure, which is convenient for use.

[0023] The connection structure includes a first fixing rod 8, which is fixedly installed on one side of one of the connecting plates 7. A second fixing rod 9 is fixedly installed on one side of the other connecting plate 7. An annular buckle plate 10 is fixedly installed inside the second fixing rod 9. A plug-in post 11 is fixedly installed at one end of the first fixing rod 8 and is slidably installed inside the second fixing rod 9. The annular buckle plate 10 is fastened to the outside of the plug-in post 11. After the annular plate 5 is connected to the filter element body 3, the plug-in post 11 at the bottom of the first fixing rod 8 will be inserted into the second fixing rod 9. The annular buckle plate 10 inside the second fixing rod 9 will be fastened to the outside of the plug-in post 11, thereby limiting the plug-in post 11 and connecting the first fixing rod 8 and the second fixing rod 9, thereby connecting the two annular plates 5 and facilitating the disassembly and assembly of the filter element body 3.

[0024] The inner wall of the annular plate 5 has a groove, and the rubber ring 6 is embedded in the groove to increase the friction between the annular plate 5 and the filter element body 3.

[0025] The second fixing rod 9 has a sliding groove inside, and the plug-in post 11 is slidably installed inside the sliding groove. The second fixing rod 9 is connected to the first fixing rod 8 by inserting the plug-in post 11 into the second fixing rod 9.

[0026] The outer side of the plug-in post 11 is provided with a slot, and the annular buckle plate 10 is fastened to the slot by interference fit, thereby limiting the plug-in post 11.

[0027] In this embodiment, the air purifier body 1 is an air purifier model 2 manufactured by Beijing Xiaomi Technology Co., Ltd., which has an air filtration and purification function. Since the structure and operating principle of this model of air purifier 2 are existing technologies, its structure and operating principle will not be described in detail here.

[0028] The working principle or structural principle is as follows: During use, two annular plates 5 are fitted onto both ends of the filter element body 3. The rubber rings 6 inside the annular plates 5 increase the friction between the annular plates 5 and the filter element body 3. After the annular plates 5 and the filter element body 3 are connected, the insertion post 11 at the bottom of the first fixing rod 8 is inserted into the second fixing rod 9. The annular buckle plate 10 inside the second fixing rod 9 is fastened to the outside of the insertion post 11, thereby limiting the insertion post 11 and connecting the first fixing rod 8 and the second fixing rod 9, thus connecting the two annular plates 5. The filter element body 3 is installed inside the air purifier body 1 through the first fixing rod 8 and the second fixing rod 9. When replacement is needed, the cover plate 2 is opened, and the filter element body 3 is pulled out from inside the air purifier body 1 through the first fixing rod 8 and the second fixing rod 9, thus facilitating disassembly and replacement.
