[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-6 A dust separation and screening device that is easy to clean includes a box body 1. The upper end of the box body 1 is in contact with a cover 2. The cover 2 has multiple air inlets 21. The design of the air inlets 21 allows dust to enter the box body 1 through the cover 2. The outer side of the cover 2 is in contact with a limiting plate 3. A limiting block 31 is fixedly connected to the outer side of the box body 1. The limiting plate 3 is in contact with the box body 1 and is slidably connected to the limiting block 31. A limiting rod 32 is fixedly connected to the side of the limiting plate 3 near the cover 2 and is slidably connected to the cover 2.

[0023] Please see Figure 2-6 A fixing plate 33 is fixedly connected inside the cover 2. The fixing plate 33 contacts the limiting plate 3. The fixing plate 33 is slidably connected to the limiting rod 32. The design of the fixing plate 33 can limit the limiting rod 32. A spring 34 is provided on the outside of the limiting rod 32. One end of the spring 34 contacts the limiting rod 32, and the other end of the spring 34 contacts the fixing plate 33. The design of the spring 34 can drive the limiting plate 3 to limit the cover 2. A fan 4 is in contact with the outside of the box 1. A filter screen 41 is slidably connected inside the box 1. The filter screen 41 contacts the fan 4. A disassembly mechanism 5 is provided on the box 1.

[0024] Please see Figure 2-6The disassembly mechanism 5 includes a slider 51, which is slidably connected inside the housing 1. A locking block 52 is fixedly connected to the side of the slider 51 near the fan 4. A locking groove 53 is opened inside the fan 4. The locking block 52 contacts the housing 1 and is slidably connected to the locking groove 53. A threaded rod 54 is rotatably connected inside the housing 1. The outer side of the threaded rod 54 is provided with positive and negative threads. The threaded rod 54 is threadedly connected to the slider 51. A retaining ring 55 is fixedly connected to the outer side of the threaded rod 54 and contacts the inner wall of the housing 1. The retaining ring 55 can limit the threaded rod 54. A knob 56 is fixedly connected to the lower end of the threaded rod 54 and contacts the housing 1. The design of the disassembly mechanism 5 makes it easy to disassemble and clean the filter screen 41.

[0025] The specific implementation process of this utility model is as follows: When in use, by moving the limiting plate 3 away from the box 1, the limiting plate 3 drives the limiting rod 32 to slide out in the fixed plate 33, which can squeeze the spring 34 and make the limiting plate 3 slide off the limiting block 31, thus releasing the limitation on the cover 2, and the cover 2 can be disassembled, thereby facilitating the cleaning of the box 1.

[0026] By rotating the knob 56, the knob 56 drives the threaded rod 54 to rotate, causing the threaded rod 54 and the slider 51 to move in a threaded motion. This causes the slider 51 to move on the threaded rod 54, which in turn causes the locking block 52 to move. The locking block 52 then slides in the slot 53 on the fan 4, so that the locking block 52 is no longer locked to the fan 4. This allows the fan 4 to be disassembled, which in turn facilitates the disassembly and cleaning of the filter screen 41.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
