[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] like Figure 1-4As shown, a telescopic air filter provided by an embodiment of the utility model includes a support box 1, folding frames 2 are provided at both ends of the support box 1, corners 9 are provided on the upper and lower sides of the folding frame 2, a slide groove 4 is provided on one side of the folding frame 2, a telescopic frame 3 is slidably connected inside the slide groove 4, and filter cotton 6 is provided inside the support box 1 and the telescopic frame 3.

[0024] Specifically, in this embodiment, a support box 1 is included, and folding frames 2 are provided at both ends of the support box 1. Corners 9 are provided on the upper and lower sides of the folding frame 2, and the folding corners 9 are 90°. A slide groove 4 is provided on one side of the folding frame 2, and a telescopic frame 3 is slidably connected inside the slide groove 4. Filter cotton 6 is provided inside the support box 1 and the telescopic frame 3. By sliding the telescopic frame 3 inside the slide groove 4, the filter cotton 6 can be stretched or folded, so that the filter cotton 6 can be adapted to more filtering devices. At the same time, it can reduce space and transportation costs while folding, and it is more practical.

[0025] The utility model provides a telescopic air filter, which can fold the frame by cooperating with the folding corner 9 and the folding frame 2, and then the telescopic frame 3 can slide inside the slide groove 4, so that the filter cotton 6 can be folded, and then the air filter device can be compressed, thereby greatly reducing the size and transportation space, greatly reducing the transportation cost.

[0026] In an embodiment provided by the utility model, the filter cotton 6 is composed of a plurality of W-shaped structures connected together, and a wire mesh 7 is provided on the outer surface of the filter cotton 6. The wire mesh 7 is used to fix the filter cotton 6 and facilitate the expansion and contraction of the filter cotton 6 so that the filter cotton 6 can be adapted to filters of different sizes. The filter cotton 6 is used to filter dust in the air.

[0027] In another embodiment provided by the utility model, a limiting strap 8 is provided above the wire mesh 7, and the limiting strap 8 is linearly arranged above the wire mesh 7. The limiting strap 8 is used to increase the structural strength of the filter cotton 6, so that the filter cotton 6 is not easily deformed. The limiting strap 8 can also serve as a pre-filtering layer of the filter cotton 6, thereby reducing the filtering burden of the filter cotton 6, increasing the processing capacity of the filter cotton 6, extending the life of the filter cotton 6, and reducing investment and labor costs.

[0028] In another embodiment provided by the utility model, one end of the folding frame 4 is fixedly connected to the supporting box 1, and a circular hole 5 is formed on the outer surface of one end of the folding frame 2 away from the supporting box 1, and the circular hole 5 is used for the passage of bolts.

[0029] In an embodiment provided by the utility model, a threaded hole 10 is opened on the outer surface of the telescopic frame 3, and the position of the threaded hole 10 corresponds to the position of the circular hole 5 on the folding frame 2. The bolt passes through the circular hole 5 and cooperates with the threaded hole 10 to limit the telescopic frame 3 and fix the telescopic frame 3 on the folding frame 2.

[0030] In another embodiment provided by the utility model, the folded corner 9 is arranged near one end of the support box 1, and the folded length of the folded frame 2 is half of the length of the telescopic frame 3. By setting the folded length of the folded frame 2 to half of the length of the telescopic frame 3, the space can be better utilized to make the filter device body into a square structure, which is convenient for transportation and greatly saves transportation costs.

[0031] Working principle: When transporting multiple air filters, remove the bolts on the round hole 5 and the threaded hole 10. After removing the bolts, the telescopic frame 3 can be moved inward for compression, so that the filter cotton 6 and the wire mesh 7 can be moved inward and compressed, and the folding frame 2 can be folded by the folding corner 9, which can greatly reduce the size of the filter device and reduce the space occupancy of the filter device, thereby greatly reducing the transportation cost. When the air filter is in use, the above steps can be reversed.

[0032] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
