[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0023] Reference Figures 1 to 5 As shown, this utility model discloses a vacuum cleaner with a quickly detachable filter element. A base 12 is fixedly connected to the bottom of the vacuum cleaner body 1. A limiting ring 13 is fixedly connected to the inner side of the vacuum cleaner body 1. A mounting plate 14 is slidably connected to the inner side of the limiting ring 13. A motor 15 is fixedly connected to the top of the mounting plate 14. A filter element 16 is disposed at the bottom of the mounting plate 14. A first sliding groove 17 is formed at the top of the mounting plate 14. A first slider 18 is slidably connected to the inner side of the first sliding groove 17. A limiting block 19 is fixedly connected to the side of the first slider 18. The limiting block 19 is slidably connected to the mounting plate 14. An annular groove 110 is formed on the inner side of the limiting ring 13. A limiting groove 111 is formed on the inner side of the limiting ring 13. The limiting groove 111 and the limiting block 16 are connected to each other. 9. Sliding connection; During operation, when the filter element 16 needs to be disassembled, pull the first slider 18 towards the center. The first slider 18 drives the limiting block 19 to move towards the center, so that the limiting block 19 separates from the limiting groove 111. Then, the mounting plate 14 can be rotated, and the mounting plate 14 drives the limiting block 19 to rotate inside the annular groove 110. When the limiting block 19 is aligned with the edge of the annular groove 110, the mounting plate 14 can be pulled up, and the mounting plate 14 drives the limiting block 19 to move out of the annular groove 110. The mounting plate 14 then takes out the filter element 16. This step, by pulling the limiting block 19 towards the center and then driving the mounting plate 14 to rotate, and then moving the mounting plate 14 upward to remove the filter element 16, achieves the effect of quick disassembly of the filter element 16.

[0024] Reference Figure 4 and Figure 5 As shown, an insert block 21 is slidably connected to the inner side of the first slider 18. The insert block 21 is slidably connected to the mounting plate 14. A movable plate 22 is fixedly connected to the top of the insert block 21, and a handle 23 is fixedly connected to the top of the movable plate 22. During operation, an unseen insertion hole is opened inside the first slide groove 17. When the insert block 21 is inserted into the mounting plate 14 through the insertion hole, the insert block 21 is positioned. When the mounting plate 14 needs to be disassembled, the movable plate 22 can be pulled up through the handle 23 to separate the bottom insert block 21 from the mounting plate 14. Then the first slider 18 can be pulled to move. This step can position the first slider 18 through the connection between the insert block 21 and the mounting plate 14, preventing the limiting block 19 from separating from the limiting groove 111 and increasing the stability when the limiting block 19 and the limiting groove 111 are connected.

[0025] Reference Figure 4 As shown, a sealing block 31 is fixedly connected to the bottom of the mounting plate 14, and the insert 21 is slidably connected to the sealing block 31. During operation, the insert 21 can pass through the mounting plate 14 and be inserted into the sealing block 31, which increases the stability of the connection between the insert 21 and the mounting plate 14. This step can increase the stability of the insert 21 and seal the connection between the insert 21 and the mounting plate 14.

[0026] Reference Figure 3 As shown, a spring 41 is fixedly connected to the inner side of the first slide groove 17, and one end of the spring 41 is fixedly connected to the first slider 18. During operation, when the first slider 18 is moved, the first slider 18 squeezes the spring 41, and the spring 41 can push the limiting block 19 to automatically insert into the limiting groove 111 through the first slider 18. This step can increase the stability of the limiting block 19 inserting into the limiting groove 111 through the spring 41.

[0027] Reference Figure 2 As shown, a sealing ring 51 is fixedly connected to the inner side of the vacuum cleaner body 1. The top of the sealing ring 51 is in contact with the limiting ring 13 and the mounting plate 14. During operation, the sealing ring 51 is located at the bottom of the limiting ring 13 and the mounting plate 14 and supports the mounting plate 14. This step, by supporting the bottom of the mounting plate 14 with the sealing ring 51, can increase the sealing performance at the connection between the mounting plate 14 and the limiting ring 13.

[0028] Reference Figure 2As shown, a cleaning ring 61 is fixedly connected to the inner side of the vacuum cleaner body 1, and a first scraper 62 is fixedly connected to the inner side of the cleaning ring 61. During operation, the cleaning ring 61 and the first scraper 62 are located on the outer side of the filter element 16. When the mounting plate 14 drives the filter element 16 to rotate, the inner sides of the cleaning ring 61 and the first scraper 62 can scrape the surface of the filter element 16. This step can scrape and clean the surface of the filter element 16 through the cleaning ring 61 and the first scraper 62, reducing the dust adsorbed on the surface of the filter element 16 when it is removed.

[0029] Reference Figure 2 As shown, a second scraper 71 is fixedly connected to the inner side of the first scraper 62, and the top of the second scraper 71 is in contact with the filter element 16. During operation, the second scraper 71 can support the bottom of the filter element 16. This step is achieved by rotating the filter element 16, causing the bottom of the filter element 16 to rub against the second scraper 71, thereby reducing the dust adsorbed on the bottom of the filter element 16 when it is removed.

[0030] Reference Figure 5 As shown, a roller 81 is rotatably connected inside the limiting block 19, and the surface of the roller 81 is in contact with the annular groove 110. During operation, when the limiting block 19 moves, it drives the roller 81 to move. When the limiting block 19 rotates inside the annular groove 110, the surface of the roller 81 is in contact with the inner wall of the annular groove 110. This step can reduce the friction generated when the limiting block 19 rotates inside the annular groove 110.

[0031] Working principle: When the insert 21 is inserted into the mounting plate 14, the insert 21 is positioned. When the mounting plate 14 needs to be disassembled, the handle 23 can be used to pull up the moving plate 22, causing the bottom insert 21 to separate from the mounting plate 14. At the same time, the bottom of the insert 21 separates from the sealing block 31. Then, the first slider 18 can be pulled to move towards the center. When the filter element 16 needs to be disassembled, the first slider 18 is pulled towards the center, which drives the limiting block 19 to move towards the center, causing the limiting block 19 to separate from the limiting groove 111. Then, the mounting plate 14 can be rotated, which drives the limiting block 19 to rotate inside the annular groove 110. When the limiting block 19 and the annular groove 110 are in contact, the limiting block 19 rotates within the annular groove 110. When the edges are aligned, the mounting plate 14 can be pulled up, and the mounting plate 14 will drive the limiting block 19 to move out of the annular groove 110. The mounting plate 14 will also bring out the filter element 16. When the limiting block 19 moves, it will drive the roller 81 to move. When the limiting block 19 rotates inside the annular groove 110, the surface of the roller 81 will fit against the inner wall of the annular groove 110. When the first slider 18 is moved, the first slider 18 will squeeze the spring 41. The spring 41 can push the limiting block 19 to automatically insert into the limiting groove 111 through the first slider 18. When the mounting plate 14 drives the filter element 16 to rotate, the inner sides of the cleaning ring 61, the first scraper 62 and the second scraper 71 can scrape the surface of the filter element 16.

[0032] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
