A plurality of connecting rods 105a are fixedly provided on the outer wall of the fan 105 driving device, and one end of the connecting rod 105a away from the fan 105 is fixedly connected to the inner wall of the vent 104, and the fan 105 is convenient for being assembled in the vent 104 through the connecting rod 105a.

A first bevel gear 106 is fixedly provided at the bottom of the rotating shaft of the fan 105. When the power box 102 is inserted into the box body 101, the heat generated by the power box 102 is absorbed by the heat sink 103, and the heat of the heat sink 103 is discharged to the outside of the box body 101 through the vent 104 through the forward operation of the fan 105, thereby achieving heat dissipation for the power box 102. At the same time, the airflow passing through the vent 104 is easily filtered through the filter 104a, thereby reducing the possibility of continuous accumulation of dust inside the box body 101.

The dust removal mechanism 200 includes a screw member 201 rotatably arranged in the box body 101, and dust boxes 202 are arranged on both sides of the box body 101.

A one-way bearing 203 is fixedly sleeved on the screw member 201. The one-way bearing 203 is a kind of bearing that can rotate freely in one direction and is locked in another direction. A second bevel gear 204 corresponding to the first bevel gear 106 is fixedly sleeved on the outer wall of the one-way bearing 203, and the second bevel gear 204 is meshed with the first bevel gear 106. When the fan 105 is running in the forward direction, it drives the first bevel gear 106 and the second bevel gear 204 to rotate. At this time, the outer ring of the one-way bearing 203 rotates, and its inner ring and the screw member 201 remain stationary; when the fan 105 is running in the reverse direction, it drives the first bevel gear 106 to rotate, and then the first bevel gear 106 drives the second bevel gear 204 and the one-way bearing 203 to rotate. At this time, the one-way bearing 203 is locked and drives the screw member 201 to rotate.

Internal thread blocks 205 are movably sleeved on both ends of the screw member 201 and cooperate with the screw member 201 thread. The screw member 201 is provided with thread grooves with opposite thread directions at both ends. A first scraper 206 for cleaning the heat sink 103 is fixedly provided at the bottom of the internal thread block 205. When the fan 105 runs in the reverse direction, it drives the first bevel gear 106 to rotate, and prompts the second bevel gear 204 and the one-way bearing 203 to drive the screw member 201 to rotate. When the screw member 201 rotates, the internal thread block 205 drives the first scraper 206 to reciprocate along the axial direction of the screw member 201, so that the dust on the surface of the heat sink 103 is continuously scraped by the first scraper 206.

A connecting block 206a is fixedly provided at the bottom of the internal thread block 205, the top surface of the first scraper 206 is fixedly connected to the connecting block 206a, and a plurality of cleaning strips 206b corresponding to the fins of the heat sink 103 are fixedly provided on the bottom surface of the first scraper 206, and the cleaning strips 206b are slidably matched with the fins of the heat sink 103. When the internal thread block 205 moves, the connecting block 206a, the first scraper 206 and the cleaning strip 206b are driven to move by the internal thread block 205, and at this time, the first scraper 206 and the cleaning strip 206b cooperate to scrape the surface of the heat sink 103 and the surface of the fin.

Two hinged rods 207 are horizontally arranged on the side of the first scraper 206 facing the dust box 202, one end of the two hinged rods 207 is hinged to the first scraper 206, and the other end of the two hinged rods 207 is vertically arranged with a second scraper 208 and hinged to the second scraper 208, the second scraper 208 fits the surface of the dust box 202, and the second scraper 208 is slidably matched with the dust box 202 and is slidably connected along the horizontal direction of the second scraper 208.

Specifically, the hinged rod 207 has a first end and a second end. The first end of the hinged rod 207 is hinged to a side of the dust box 202 through a hinge and a connecting block 206a. The second end of the hinged rod 207 is hinged to the lower end of the second scraper 208 through a hinge. When the fan 105 rotates in the reverse direction and drives the first bevel gear 106 to rotate, the second bevel gear 204 and the one-way bearing 203 drive the screw member 201 to rotate, and cause the first scraper 206 to reciprocate along the axial direction of the screw member 201. When the first scraper 206 moves toward the middle of the box body 101, the first scraper 206 drives the connecting block 206a to move and pulls the first end of the hinged rod 207 to move. At this time, the second ends of the two hinged rods 207 drive the second scraper 208 to move toward the screw member 201 at the same time, and scrape the dust on the surface of the dust box 202.

When the first scraper 206 moves toward the dust box 202, the connecting block 206a pushes the first end of the hinged rod 207 to move. At this time, the second ends of the two hinged rods 207 drive the second scraper 208 to move toward both ends of the dust box 202 and reset at the same time, and the dust on the surface of the dust box 202 is scraped off in this reciprocating manner.

Furthermore, both ends of the second scraper 208 facing the dust box 202 are fixedly provided with limit plates 208a, the shape of the limit plate 208a is L-shaped, and the top and bottom of the dust box 202 are provided with limit grooves 202a corresponding to the limit plates 208a, the limit plates 208a are located in the limit grooves 202a and slide with the inner wall of the limit grooves 202a, the limit grooves 202a are arranged along the horizontal direction of the dust box 202, and the inner contour of the cross section of the limit groove 202 is L-shaped and slides with the limit grooves 202a. The limiting plate 208a is adapted to the limiting groove 202a, and the second scraper 208 can be easily assembled on the dust box 202 through the cooperation of the limiting plate 208a and the limiting groove 202a, so that when the first scraper 206 moves, it drives one end of the hinged rod 207 to move, and then drives the second scraper 208 to move along the surface of the dust box 202 through the hinged rod 207 to scrape the dust on the surface of the dust box 202. At the same time, the limiting plate 208a cooperates with the limiting groove 202a to increase the stability of the second scraper 208 when moving.

The dust box 202 is provided with a storage space, and a piston plate 209 is movably arranged in the storage space of the dust box 202. The top surface of the piston plate 209 is connected to the inner top wall of the dust box 202 by setting a spring 210. The bottom surface of the piston plate 209 is fixedly provided with a steel cable 211. The end of the steel cable 211 away from the piston plate 209 passes through the dust box 202 and is fixedly connected to the first scraper 206. The lower end of the dust box 202 facing the second scraper 208 is fixedly plugged with a plurality of air inlet nozzles 212. When the first scraper 206 is facing When it moves toward the middle of the box body 101, it pulls the steel cable 211 to move and drives the piston plate 209 to move downward. At this time, the piston plate 209 moves downward and pulls the spring 210 to stretch and deform. When the first scraper 206 moves toward the dust box 202, the dust on the surface of the heat sink 103 is pushed toward the air inlet nozzle 212. At this time, the steel cable 211 loses its pulling force, and then the piston plate 209 is pulled upward through the spring 210. At this time, the air inlet nozzle 212 inhales air, and then the dust on the surface of the heat sink 103 is sucked into the dust box 202 through the air inlet nozzle 212.

An exhaust pipe 213 is fixedly connected to the lower end of the dust collecting box 202 away from the second scraper 208. When the first scraper 206 moves toward the middle of the box body 101, it pulls the steel cable 211 to move and drives the piston plate 209 to move downward. At this time, the piston plate 209 discharges the dust-containing air in the box body 101 through the exhaust pipe 213.

One-way valves are provided in the air inlet nozzle 212 and the exhaust pipe 213. The air inlet nozzle 212 and the exhaust pipe 213 are both connected to the lower cavity inside the box body 101. The air inlet end of the air inlet nozzle 212 is inserted into the heat sink 103. By setting the one-way valve, the airflow can only enter the dust collecting box 202 through the air inlet nozzle 212, and the airflow in the dust collecting box 202 can only be discharged through the exhaust pipe 213, and then the dust is collected centrally through an external collection device.

The upper end of the dust box 202 facing the second scraper 208 is fixedly provided with a jet component 214, and the air inlet end of the jet component 214 is connected to the internal cavity of the dust box 202. The jet component 214 includes a hollow plate 214a, which is fixedly provided on the side of the dust box 202 facing the inner wall of the box body 101, and the hollow plate 214a is connected to the upper cavity inside the dust box 202 through a conduit 214b. A plurality of nozzles 214c are fixedly plugged on the side of the hollow plate 214a facing the second scraper 208, and the air inlet end of the nozzle 214c is connected to the inner wall of the box body 101. It is connected to the internal space of the hollow plate 214a. When the piston plate 209 moves upward, the airflow in the upper cavity is transported to the hollow plate 214a through the conduit 214b, and then the airflow in the hollow plate 214a is ejected through the cooperation of a plurality of nozzles 214c, so that the dust attached to the inner wall of the box body 101 is swept down by the ejected airflow, and falls on the heat sink 103 with the weight of the dust, and then the dust is pushed to the air inlet nozzle 212 for attachment through the first scraper 206, and finally the dust is sucked into the dust collecting box 202 through the air inlet nozzle 212.

The accommodating space of the dust box 202 is divided into an upper cavity and a lower cavity by the piston plate 209. When the first scraper 206 moves toward the middle of the heat sink 103, the first scraper 206 drives the steel cable 211 to pull the piston plate 209 downward. At this time, the piston plate 209 discharges the airflow containing dust in the lower air through the exhaust pipe 213, and pulls the spring 210 to stretch and deform as the piston plate 209 moves downward.

When the first scraper 206 moves toward the dust box 202, it pushes the dust on the surface of the heat sink 103 to the vicinity of the air inlet nozzle 212, and causes the steel cable 211 and the piston plate 209 to lose tension. At this time, the spring 210 recovers its deformation and pulls the piston plate 209 upward. As the piston plate 209 moves upward, the airflow in the upper cavity is pushed into the jet element 214, and then the airflow ejected through the jet element 214 sweeps the dust attached to the inner wall of the box body 101, and as the piston plate 209 moves upward, the dust on the heat sink 103 is sucked into the dust box 202 through the air inlet nozzle 212.

In summary, when the fan 105 rotates in the reverse direction, it drives the first bevel gear 106 to rotate, and then the first bevel gear 106 drives the second bevel gear 204 and the one-way bearing 203 to rotate. At this time, the one-way bearing 203 is locked and drives the screw member 201 to rotate. As the screw member 201 rotates, the internal thread block 205 drives the first scraper 206 to reciprocate along the axial direction of the screw member 201.

The first scraper 206 pulls the steel cable 211 to move and drives the piston plate 209 to move downward. At this time, the piston plate 209 discharges the dust-containing air in the box body 101 through the exhaust pipe 213. When the first scraper 206 moves toward the dust box 202, the dust on the surface of the heat sink 103 is pushed toward the air inlet nozzle 212. At this time, the steel cable 211 loses its pulling force, and then the piston plate 209 is pulled upward by the spring 210. At this time, the air pressure in the bottom space of the box body 101 is reduced, and then the dust on the surface of the heat sink 103 is sucked into the dust box 202 through the nozzle 214c, and as the piston plate 209 moves upward, the airflow in the top cavity of the dust box 202 is pushed into the jet component 214, so that the airflow ejected by the jet component 214 is used to blow away the dust on the box body 101 and the dust box 202.

Example 2

Referring to Fig. 4-7, it is a second embodiment of the present invention, which is based on the previous embodiment. The connection between the two ends of the screw rod 201 and the two dust collecting boxes 202 is provided with a round tube 201b, and the round tube 201b is fixedly arranged on the dust collecting box 202. The two ends of the two screw rods 201 pass through the two round tubes 201b and are rotatably plugged into the two dust collecting boxes 202. The outer wall of the round tube 201b is symmetrically provided with two movable grooves 201c, and the two movable grooves 201c are movably provided with a limit rod 201d. The movable groove 201c is arranged along the axial direction of the round tube 201b and has a long strip structure, so as to facilitate the limit rod 201d. The outer walls of both ends of the screw rod 201 are provided with wave grooves 201a in and along the movable groove 201c, and the wave grooves 201a are provided on the circumference of the two ends of the screw rod 201 in a wave-like shape to form a surrounding structure. One end of the limiting rod 201d passes through the movable groove 201c and is inserted into the wave groove 201a and slides with the inner wall of the wave groove 201a. The other end of the limiting rod 201d is fixedly connected with a knocking rod 201e. The knocking rod 201e is arranged toward the dust box 202 and perpendicular to the limiting rod 201d. The limiting rod 201d is fixedly connected to the dust box 202 through a tension spring 201f.

When the screw rod 201 rotates, the limiting rod 201d slides along the inner wall of the wave groove 201a, thereby causing the limiting rod 201d to reciprocate along the inner wall of the movable groove 201c. When the limiting rod 201d drives the knocking rod 201e to move toward the dust box 202, the knocking rod 201e knocks the dust box 202, causing the dust box 202 to vibrate and shake off the dust. At the same time, the second scraper 208 is used to scrape the dust, so the dust cleaning effect inside the box body 101 is better.

In summary, when the screw member 201 rotates, the limiting rod 201d slides along the inner wall of the wave groove 201a, thereby causing the limiting rod 201d to reciprocate along the inner wall of the movable groove 201c. When the limiting rod 201d drives the knocking rod 201e to move toward the dust box 202, the knocking rod 201e knocks the dust box 202 to cause the dust box 202 to vibrate and shake the dust off, and at the same time cooperates with the second scraper 208 to scrape the dust;

When the first scraper 206 moves toward the middle of the box body 101 , it pulls one end of the hinge rod 207 to move. At this time, the other end of the hinge rod 207 pulls the second scraper 208 to move and scrape the dust on the surface of the dust box 202 off.

In summary, the above two embodiments can be combined, and the overall action process after the combination is: when the power box 102 is inserted into the box body 101, the heat generated by the power box 102 is absorbed by the heat sink 103, and the heat of the heat sink 103 is discharged to the outside of the box body 101 through the vent 104 by the fan 105, thereby achieving heat dissipation of the power box 102;

When the fan 105 rotates in the reverse direction, it drives the first bevel gear 106 to rotate, and then the first bevel gear 106 drives the second bevel gear 204 and the one-way bearing 203 to rotate. At this time, the one-way bearing 203 is locked and drives the screw rod 201 to rotate. As the screw rod 201 rotates, the internal thread block 205 drives the first scraper 206 to reciprocate along the axial direction of the screw rod.

When the first scraper 206 moves toward the middle of the box body 101, it pulls one end of the hinge rod 207 to move, and at this time, the other end of the hinge rod 207 pulls the second scraper 208 to move and scrape the dust on the surface of the dust box 202;

At the same time, the first scraper 206 pulls the steel cable 211 to move and drives the piston plate 209 to move downward, and as the piston plate 209 moves downward, the spring 210 is stretched and deformed. At this time, the piston plate 209 discharges the air containing dust in the box body 101 through the exhaust pipe 213, and then the dust is collected centrally by an external collection device;

When the first scraper 206 moves toward the dust box 202, the dust on the surface of the heat sink 103 is pushed toward the air inlet nozzle 212. At this time, the steel cable 211 loses its tension, and then the piston plate 209 is pulled upward by the spring 210. As the piston plate 209 moves upward, the air flow in the top cavity of the dust box 202 is pushed into the jet component 214, so that the air flow ejected by the jet component 214 blows away the dust on the box body 101 and the dust box 202, and as the piston plate 209 moves upward, the air inlet nozzle 212 starts to inhale, and then the dust on the surface of the heat sink 103 is sucked into the dust box 202 through the air inlet nozzle 212 for collection.
