[0036] The cleaning assembly 4 includes a second rotating shaft 41, a protective flap 42, a torsion spring 43 and a cleaning roller 44; the second rotating shaft 41 is rotatably mounted on opposite side walls of the protective cover 51, the second rotating shaft 41 is arranged near the top of the protective cover 51, one end of the protective flap 42 is fixedly connected to the second rotating shaft 41, the protective flap 42 extends out of the protective cover 51, and the cleaning roller 44 is rotatably mounted on the end of the protective flap 42 away from the second rotating shaft 41; the torsion spring 43 is sleeved on the second rotating shaft 41, one end of the torsion spring 43 is fixedly connected to the inner wall of the protective cover 51, and the other end of the torsion spring 43 is fixedly connected to the protective flap 42. As an embodiment, in order to facilitate the fixed connection of the protective flap 42 with the second rotating shaft 41, a cylindrical barrel can be provided at one end of the protective flap 42 connected to the second rotating shaft 41, the protective flap 42 is fixedly connected to the outer wall of the cylindrical barrel, and the cylindrical barrel is fixedly sleeved on the second rotating shaft 41.

The cleaning roller 44 is rotatably mounted between the two side walls of the U-shaped plate. Bristles are evenly arranged on the peripheral side surface of the cleaning roller 44. As an embodiment, in order to make it easier for the cleaning roller 44 to flip downward along the rotation center as the protective cover 51 moves further toward the cabinet 1 after the cleaning roller 44 abuts against the heat dissipation filter 2, the protective flap 42 can be slightly tilted downward at a certain angle when installing.

[0037] The inner bottom of the groove 101 is provided with a receiving through hole 102 adapted to the cleaning roller 44. The receiving through hole 102 enables the cleaning roller 44 to be inserted into the receiving through hole 102 when the protective cover 51 is covered in the groove 101, so as to limit the cleaning roller 44.

[0038] Description of working process:

[0039] When the heat dissipation filter 2 needs to be cleaned, the first drive motor 33 can be started, the first drive motor 33 rotates forward to drive the screw 32 to rotate, the screw 32 rotates to drive the slider 34 to move along the screw 32, the slider 34 drives the protective cover 51 to move in the direction close to the cabinet 1 through the connecting rod 35, the cleaning roller 44 squeezes the heat dissipation filter 2 and rotates, as the protective cover 51 further approaches the cabinet 1, the protective flap 42 rotates downward, causing the torsion spring 43 to deform, and the cleaning roller 44 moves downward along the heat dissipation filter 2, thereby cleaning the heat dissipation filter 2. When the first drive motor 33 reverses, it drives the screw 32 to reverse, the slider 34 pushes the protective cover 51 to move in the direction away from the cabinet 1 through the connecting rod 35, the torsion spring 43 drives the protective flap 42 to flip upward, and the cleaning roller 44 moves upward along the heat dissipation filter 2, which can further clean the heat dissipation filter 2.

[0040] When the cabinet 1 is not in use temporarily, the first drive motor 33 rotates forward to drive the screw 32 to rotate, and the rotation of the screw 32 drives the slider 34 to move along the screw 32. The slider 34 drives the protective cover 51 to move toward the cabinet 1 through the connecting rod 35, and the cleaning roller 44 squeezes the heat dissipation filter 2 and rotates. As the protective cover 51 further approaches the cabinet 1, the protective flap 42 rotates downward, causing the torsion spring 43 to deform, and the cleaning roller 44 moves downward along the heat dissipation filter 2 to clean the heat dissipation filter 2. When the protective cover 51 fits the outer shell of the cabinet 1, that is, when the protective cover 51 is covered in the groove 101, the cleaning roller 44 is inserted into the accommodating through hole 102. The protective cover 51 can effectively reduce the dust in the air from adhering to the heat dissipation filter 2 when the cabinet 1 is not in use.

[0041] As an embodiment, the second rotating shaft 41 is arranged near the bottom of the protective cover 51, so that when the cleaning roller 44 squeezes the heat dissipation filter 2 and rotates, as the protective cover 51 further approaches the cabinet 1, the protective flap 42 rotates upward, causing the torsion spring 43 to deform, and the cleaning roller 44 moves upward along the heat dissipation filter 2, thereby cleaning the heat dissipation filter 2.

[0042] In other embodiments, the protective flap 42 may also be replaced by a frame or a connecting rod.

[0043] Embodiment 2

[0044] This embodiment is a further improvement on the basis of the first embodiment, and the same parts as the first embodiment are not repeated, and only the improved parts are described.

[0045] See also Figure 1 - Figure 5As shown, the cabinet 1 is also equipped with an auxiliary dustproof structure 6, which includes a mounting block 61 and a microporous guide plate 62; the mounting block 61 is engaged with a mounting slot 103 provided on the cabinet 1, the mounting slot 103 is communicated with the interior of the cabinet 1, and the mounting slot 103 is provided on the side wall adjacent to the groove 101; the microporous guide plate 62 is installed in the cabinet 1 and connected to the mounting block 61. After the microporous guide plate 62 is installed in the cabinet 1, it is directly opposite to the heat dissipation filter 2, and the microporous guide plate 62 can filter the air filtered by the heat dissipation filter 2 again, thereby further reducing the dust from entering the cabinet 1. The mounting block 61 is engaged with the cabinet 1, which is convenient for removing the auxiliary dustproof structure 6 from the cabinet 1 for maintenance or replacement.

[0046] When the cabinet is used in an environment with heavy dust, in order to prevent dust from concentrating on one area of ​​the microporous guide plate 62, the angle of the microporous guide plate 62 may be set to be adjustable. Specifically, the following methods may be used:

[0047] A third rotating shaft 63 is rotatably mounted on the mounting block 61, one end of the third rotating shaft 63 passes through the mounting block 61 and is fixedly connected to a mounting tube 64 located in the cabinet 1, the center line of the mounting tube 64 coincides with the center line of the third rotating shaft 63, and a positioning groove 641 is opened on the side wall of the mounting tube 64 along its length direction; a mounting column 65 matched with the mounting tube 64 is fixedly mounted on the microporous guide plate 62, and a positioning bar 651 matched with the positioning groove 641 is provided on the mounting column 65.

[0048] The microporous guide plate 62 and the third rotating shaft 63 are arranged to be connected to each other, so as to facilitate the removal of the microporous guide plate 62 for replacement or cleaning. When the mounting column 65 is inserted into the mounting barrel 64, the positioning bar 651 is located in the positioning groove 641, which can prevent the microporous guide plate 62 from rotating relative to the mounting barrel 64.

[0049] In order to facilitate the fixation after the micro-hole guide plate 62 is fine-tuned in angle, the following method is adopted: the end of the third rotating shaft 63 away from the mounting tube 64 is fixedly connected to a turntable 66, and a plurality of first positioning holes 661 are provided on the turntable 66, and the plurality of first positioning holes 661 are evenly distributed along the circumferential direction of the turntable 66; a second positioning hole 104 is provided on the side wall of the cabinet 1, and the second positioning hole 104 is connected to the first positioning hole 661 by a positioning rod 67.

[0050] When the dust is heavy, pull out the positioning rod 67 and rotate the turntable 66. The turntable 66 drives the microporous guide plate 62 to tilt through the third rotating shaft 63. When the angle is adjusted, the positioning rod 67 is inserted into the second positioning hole 104 through the first positioning hole 661 opposite to the second positioning hole 104 for fixation.

[0051] By adjusting the angle of the microporous guide plate 62, the wind direction can be finely controlled to avoid the dust being concentrated in one area when there is a lot of dust, resulting in poor heat dissipation effect.

[0052] A baffle 68 is fixedly mounted on one side of the mounting block 61 away from the microporous guide plate 62, and the width of the baffle 68 is greater than the mounting slot 103. The baffle 68 not only shields the mounting slot 103 to prevent dust from entering the cabinet 1 from the connection between the mounting block 61 and the mounting slot 103, but also facilitates the removal of the auxiliary dustproof structure 6 from the cabinet 1.

[0053] The above describes in detail the structure, features and effects of the utility model based on the embodiments shown in the drawings. The above is only a preferred embodiment of the utility model, but the utility model is not limited to the scope of implementation shown in the drawings. Any changes made in accordance with the concept of the utility model, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and the drawings, should be within the protection scope of the utility model.
