In this embodiment, first, when in use, the controller 12 is used to control the fan 6 to rotate, and then the wind enters the interior of the device box 2 through the air inlet pipe 1, and then is filtered through the filter 11. After the filter 11 has been filtered for a long time, dust will accumulate on its surface. At this time, the displacement mechanism is driven to move by pulling the toggle rod 4, and the sponge 17 is driven to move and clean the surface of the filter 11. The swept dust then falls into the collection box 7. Then, when the filter 11 needs to be replaced, the mounting frame 9 is pulled out from the interior of the device box 2 by pulling the limiting mechanism and the handle 10 at the same time, and then the filter 11 is replaced, thereby reducing the time for replacing the filter 11. Then, when installing the filter 11, the filter 11 can be quickly installed through the positioning mechanisms on both sides. In summary, the problem of long-term filtering of the high-efficiency filter and the inconvenience of disassembling and installing the high-efficiency filter when it needs to be cleaned can be avoided, thereby increasing the practicality of the device and reducing the limitations of the device.

The limiting mechanism includes a clamping block 19 which is slidably connected to the inside of a fixed block 20 . A slider 25 is slidably connected to the top of the device box 2 . One side of the clamping block 19 is fixedly connected to one side of the slider 25 .

Among them, the limiting mechanism also includes a vertical plate 23, which is fixedly connected to the top of the device box 2. A guide rod 24 is slidably connected inside the vertical plate 23.

Among them, the block 19 is provided with an inclined surface, and a fixed block 20 is fixedly connected to one side of the installation frame 9, and the top of the fixed block 20 conflicts with the bottom of the block 19. When the filter 11 is replaced, the slider 25 is driven to move by pulling the guide rod 24, and the block 19 is driven to disengage from the top of the fixed block 20, and then the limit of the fixed block 20 is released. At this time, the handle 10 is pulled to drive the installation frame 9 to slide out of the inside of the device box 2, so that the filter 11 can be replaced more conveniently. Then, during installation, the bottom of the fixed block 20 conflicts with the inclined surface of the block 19, thereby driving the block 19 to move and the slider 25 to move, and then compressing the second spring 22 and driving the guide rod 24 to slide inside the vertical plate 23 to prevent the slider 25 from deviating when moving, and then driving the block 19 to limit the top of the fixed block 20 under the action of the second spring 22, thereby increasing the practicality of the device.

The displacement mechanism includes a vertical rod 14, which is fixedly connected to the inside of the displacement groove 13, a first spring 15 is sleeved on the outside of the vertical rod 14, a displacement plate 16 is slidably connected to the outside of the vertical rod 14, and the two ends of the first spring 15 are respectively fixedly connected to the bottom of the displacement plate 16 and the inner wall of the displacement groove 13, a sponge 17 is arranged on one side of the displacement plate 16, and one side of the sponge 17 contacts one side of the filter 11, and a slide groove 3 is provided on one side of the device box 2, and a toggle rod 4 is slidably connected inside the slide groove 3, and one end of the toggle rod 4 is fixedly connected to one side of the displacement plate 16. When cleaning the filter 11, the toggle rod 4 is pulled to slide inside the slide groove 3 and the displacement plate 16 is driven to move outside the vertical rod 14, and then the first spring 15 is compressed, thereby driving the sponge 17 to clean the surface of the filter 11, and then the dust on the surface of the filter 11 falls into the inside of the collection box 7, thereby extending the service life of the device.

The positioning mechanism includes a positioning groove 18, which is provided inside the device box 2. A positioning block 8 is slidably connected inside the positioning groove 18, and one side of the positioning block 8 is fixedly connected to the outer side of the installation frame 9. When installing the filter 11, the installation frame 9 can be better limited by the cooperation between the positioning block 8 and the positioning groove 18, thereby preventing the problem of deviation during installation, thereby increasing the stability of the device.

A controller 12 is fixedly mounted on one side of the device box 2 , and the fan 6 is electrically connected to the controller 12 .

Working principle: First, when in use, the controller 12 controls the fan 6 to rotate, and then the wind enters the interior of the device box 2 through the air inlet pipe 1, and then is filtered through the filter 11. After the filter 11 has been filtered for a long time, dust will accumulate on its surface. Then, by pulling the toggle rod 4 to slide inside the slide groove 3 and driving the displacement plate 16 to move on the outside of the vertical rod 14, the first spring 15 is compressed, thereby driving the sponge 17 to clean the surface of the filter 11, and then the dust on the surface of the filter 11 falls into the collection box 7, thereby extending the service life of the device.
