[0030] Example 1

[0031] Reference Figure 1-6 In the first embodiment of the present invention, a dust removal mechanism 1 is provided, including a main unit 101 and a fixed frame 102. The surface of the main unit 101 is fixedly connected to the inner wall of the fixed frame 102. A cleaning mechanism 2 is provided on both sides of the fixed frame 102. A cooperating mechanism 4 is provided on the cleaning mechanism 2. The cleaning mechanism 2 is used to move the cooperating mechanism 4. The cooperating mechanism 4 is used to clean the dust from the heat dissipation holes on both sides of the main unit 101.

[0032] Specifically, the dust removal mechanism 1 solves the problems of low efficiency and incomplete cleaning that easily causes secondary dust generation during the traditional cleaning of the heat dissipation holes of the host 101 by setting up cleaning mechanism 2 and cooperating mechanism 4 on both sides of the fixed frame 102. The fixed frame 102 is stably connected to the host 101 to ensure the structural stability of the dust removal device during operation. The cleaning mechanism 2 drives the cooperating mechanism 4 to move back and forth along the surface of the host 101 to achieve full coverage of the heat dissipation hole area by the brush plate 404, avoiding omissions. The cooperating mechanism 4 works in conjunction with the rotating brush plate 404 and electrostatic adsorption to collect dust in real time while removing accumulated dust, effectively preventing dust diffusion and improving the uniformity, safety and efficiency of dust removal.

[0033] Furthermore, the cleaning mechanism 2 is used to move the cooperating mechanism 4, and the dust on the heat dissipation holes on both sides of the host 101 is cleaned by the cooperating mechanism 4.

[0034] Example 2

[0035] In a second embodiment of the present invention, a cleaning mechanism 2 is provided, comprising a servo motor 201, a transmission component 202, a tensioning wheel 203, an adjusting screw 204, and a transmission block 205. The output end of the servo motor 201 meshes with the inner tooth surface of the transmission component 202 via a pulley. The surface of the transmission component 202 is slidably connected to the surface of the tensioning wheel 203. Both ends of the transmission component 202 mesh with the upper tooth surfaces of two adjusting screws 204, respectively. The surface of the adjusting screws 204 is threadedly connected to the inner wall of the transmission block 205. An auxiliary mechanism 3 is provided on the cleaning mechanism 2. The auxiliary mechanism 3 includes a dustproof box 301, a guide rod 302, a mounting box 303, and a guide block 304. The upper end of the fixing frame 102 is fixedly connected to the lower surface of the dustproof box 301, and the surface of the guide rod 302 is threadedly connected to the outer surface of the mounting box 303. The side surfaces are slidably connected. The two ends of the mounting box 303 are fixedly connected to the surfaces of the two guide blocks 304 respectively. The surface of the servo motor 201 is fixedly connected to the upper end of the dustproof box 301. The transmission component 202 and the tension wheel 203 are set inside the dustproof box 301. The two ends of the tension wheel 203 are rotatably connected to the inner wall of the dustproof box 301 through a rotating shaft. The upper end of the adjusting screw 204 is rotatably connected to the inner wall of the dustproof box 301. The surface of the transmission block 205 is fixedly connected to the outer surface of the mounting box 303. The lower end of the adjusting screw 204 is rotatably connected to the inner wall of the fixing frame 102. The two ends of the guide rod 302 are fixedly connected to the outer surface of the fixing frame 102. The surface of the guide block 304 is slidably connected to the inner wall of the fixing frame 102 through a sliding groove. The two side surfaces of the mounting box 303 are slidably connected to the inner wall of the fixing frame 102.

[0036] Specifically, the cleaning mechanism 2 uses a servo motor 201 to drive the transmission component 202 to rotate the adjusting screw 204, which, in conjunction with the transmission block 205, enables the linear movement of the mounting box 303. This solves the problem that the brush plate 404 cannot automatically cover the entire heat dissipation hole area during the dust cleaning process. Traditional methods require manual adjustment of the position, which has the defects of omission or inconvenience of operation. This mechanism uses a synchronous belt and a double screw linkage structure to ensure that the mounting box 303 moves smoothly in the vertical direction. Combined with the guide rod 302 and the guide block 304 for guidance and limitation, the motion accuracy and stability are improved. The tension wheel 203 effectively maintains the tension of the transmission component 202, preventing transmission asynchrony caused by loosening, and ensuring the coordinated operation of the adjusting screws 204 on both sides.

[0037] Furthermore, when the brush plate 404 begins cleaning, the servo motor 201 at the upper end of the fixed frame 102 is activated to dynamically adjust the cleaning range. The output shaft of the servo motor 201 is connected to a pulley, which is connected to the upper ends of two adjusting screws 204 vertically arranged on both sides of the fixed frame 102 via a synchronous belt. The adjusting screws 204 rotate with the fixed frame 102, and their outer threads mesh with the internal threads of the transmission block 205. The transmission block 205 is fixed to the side wall of the mounting box 303. When the servo motor 201 runs, the two adjusting screws 204 rotate synchronously through belt drive, driving the transmission block 205 to move along the screw axis, causing the mounting box 303 to move up and down along the fixed frame 102. To ensure smooth movement, the mounting box 303... The mounting box 303 slides with the guide rod 302 on the fixed frame 102 through a sliding sleeve structure. In addition, the tension wheel 203 in the transmission component 202 can adjust the tension of the synchronous belt to ensure that the adjustment screws 204 on both sides rotate in unison. As the servo motor 201 drives the mounting box 303 to move vertically, the brush plate 404 sweeps longitudinally on the surface of the heat dissipation holes. The rotation of the brush plate 404 for dust removal is combined with the linear displacement of the mounting box 303, so that the brush plate 404 can cover all the heat dissipation hole areas on both sides of the host 101, achieving dust removal without dead corners and continuous dust removal. At the same time, an electrostatic adsorption plate is set inside or in the adjacent area of ​​the mounting box 303 to collect the dust particles brushed off using the principle of electrostatic adsorption, preventing secondary dust and improving cleaning efficiency and environmental cleanliness.

[0038] Example 3

[0039] In the third embodiment of the present invention, a mating mechanism 4 is provided, comprising a stepper motor 401, a chain 402, a sprocket 403, a brush plate 404, and an electrostatic adsorption disk 405. The output end of the stepper motor 401 is fixedly connected to the inner wall of the sprocket 403. The tooth surface of the sprocket 403 meshes with the tooth surface of the chain 402 for transmission. The surface of the sprocket 403 is fixedly connected to the surface of the brush plate 404. The surface of the brush plate 404 is rotatably connected to the inner wall of the electrostatic adsorption disk 405. The surface of the stepper motor 401 is fixedly connected to the outer surface of the mounting box 303. The chain 402 and the sprocket 403 are disposed inside the mounting box 303. The inner wall of the sprocket 403 is rotatably connected to the inner wall of the mounting box 303 via a rotating shaft. The inner surface of the mounting box 303 is fixedly connected to the surface of the electrostatic adsorption disk 405. The surface of the brush plate 404 slides in contact with the outer surface of the host 101. The surface of the electrostatic adsorption disk 405 contacts the outer surface of the host 101.

[0040] Specifically, the cooperating mechanism 4 drives the sprocket 403 and chain 402 to rotate the brush plate 404 via the stepper motor 401. Combined with the electrostatic adsorption plate 405 to fix and collect dust, it solves the problems of low efficiency and difficulty in covering complex pore structures in traditional manual dust cleaning. The brush plate 404 slides in contact with the surface of the heat dissipation hole, which can penetrate into the pores for physical cleaning and improve the thoroughness of cleaning. The electrostatic adsorption plate 405 is close to the dust cleaning area and adsorbs the dust raised in real time to prevent secondary pollution. This improves the automation level and cleaning reliability of the heat dissipation hole maintenance of the host 101.

[0041] Furthermore, when cleaning the heat dissipation holes of the computer host 101, first start the stepper motor 401 on the outer fixing bracket 102 of the host 101. Its output shaft is connected to the inner wall of the central sprocket 403 of the mounting box 303. There are multiple sprockets 403 in the mounting box 303. They are driven by the meshing of the closed-loop chain 402. After the stepper motor 401 is powered on, the output shaft drives the central sprocket 403 to rotate. The power is transmitted to the other sprockets 403 through the chain 402, so that all sprockets 403 rotate synchronously. Each sprocket 403 has a brush plate 404 fixed inside. When the sprocket 403 rotates continuously, the brush plate 404 rotates coaxially. The bristles contact the surface of the heat dissipation holes of the host 101 and use the rotating mechanical sweeping to remove the dust accumulated in the holes and surrounding areas.

[0042] Working principle:

[0043] When cleaning the heat dissipation holes of the computer host 101, the stepper motor 401 mounted on the outer mounting bracket 102 of the host 101 is first started. The output shaft of the stepper motor 401 is fixedly connected to the inner wall of the sprocket 403 at the center of the mounting box 303. The mounting box 303 contains multiple sprockets 403, which are meshed and driven by a closed-loop chain 402. When the stepper motor 401 is powered on, its output shaft drives the central sprocket 403 to rotate, and transmits the power to the other sprockets 403 through the chain 402, so that all sprockets 403 rotate synchronously. The inner surface of each sprocket 403... Each component is fixed with a brush plate 404. As the sprocket 403 continues to rotate, the brush plate 404 rotates coaxially, its bristles contacting the surface of the heat dissipation holes in the main unit 101. The mechanical sweeping action generated by the rotation removes dust accumulated in the pores and surrounding areas. Simultaneously with the brush plate 404 starting to clean, the servo motor 201 at the upper end of the fixing frame 102 is activated to dynamically adjust the cleaning range. The output shaft of the servo motor 201 is connected to a pulley, which uses a synchronous belt as a transmission component 202. This pulley is also connected to the upper ends of two vertically arranged adjusting screws 204, which are vertically arranged along both sides of the fixing frame 102. It maintains a rotational fit with the transmission block 205; its outer circumferential thread meshes with the internal thread of the transmission block 205, which is fixedly connected to the side wall of the mounting box 303. When the servo motor 201 runs, it drives the two adjusting screws 204 to rotate synchronously via belt drive, thereby causing the transmission block 205 to move along the screw axis, driving the entire mounting box 303 to reciprocate up and down along the fixed frame 102. To ensure smooth movement, the mounting box 303 also slides with the guide rod 302 on the fixed frame 102 through a sliding sleeve structure, which serves as a limit and guide. In addition, the tension wheel 203 in the transmission component 202 can adjust the tension of the synchronous belt to prevent slippage and ensure the smooth operation of the two belts. The consistent rotation of the side adjustment screw 204, along with the continuous vertical movement of the mounting box 303 driven by the servo motor 201, causes the brush plate 404, originally driven by the stepper motor 401, to also perform longitudinal sweeping on the surface of the heat dissipation holes. This combination of the rotational dust removal of the brush plate 404 and the linear displacement of the mounting box 303 allows the brush plate 404 to cover all heat dissipation hole areas on both sides of the host 101, achieving a continuous dust removal operation without dead angles. At the same time, an electrostatic adsorption plate is provided inside or in the vicinity of the mounting box 303, which uses the principle of electrostatic adsorption to capture and collect the dust particles brushed off, effectively preventing secondary dust generation and improving cleaning efficiency and environmental cleanliness.

[0044] In summary, by employing multiple mechanisms—a stepper motor driving a sprocket chain to rotate the brush plate, a servo motor controlling an adjusting screw to linearly move the mounting box, and an electrostatic adsorption plate—a comprehensive and controllable dust removal effect is achieved for the computer host's heat dissipation vents.
