Referring particularly to fig. 2 and 3, in this example, the frame 34 may be a rectangular parallelepiped structure and include four rectangular frame plates connected to each other, i.e., a first frame 343 and a second frame 344 at upper and lower sides, and a third frame 345 and a fourth frame 346 at left and right sides, and the first motor 36 is disposed above the first frame 343. Note that the terms "upper", "lower", "left" and "right" used herein to describe directions are described with respect to the specific examples shown in the drawings referred to (e.g., fig. 2 and 3 herein) and are not intended to limit the scope of the present invention. In addition, the frame 34 may be constructed in other structures, not limited to four rectangular frame plates. For example, the frame 34 may also be a cylinder or a polygonal structure.

Of course, the connecting rods 391 may also be straight, or even without connecting rods 391, instead attaching the bristles 392 directly to the respective connecting shafts 311. The bristles 392 are preferably flexible bristles.
The driving unit 10 is configured to convert torque of the first motor 36 disposed above the first frame 343 into torque of the two connection shafts 311 of the two brushes 12 accommodated in the frame 34 such that the two sets of bristle assemblies 312 rotate toward the middle of the two connection shafts 311, thereby cleaning dust on the heat dissipation plate 1 and gathering the dust toward the middle of the two connection shafts 311.
Specifically, the first motor 36 has a screw 37 as an output shaft. Two ends (here, upper and lower ends) of each of the two connection shafts 311 of the two brushes 12 are rotatably connected to the oppositely disposed first and second frames 343 and 344 of the frame 34 at the upper and lower sides. Further, in this specific example, the driving unit 10 may include a central shaft 32, a gear 310, at least one pair of drive bevel gears 31, and at least one pair of driven bevel gears 33. The gear 310 is fixedly mounted coaxially to the outer surface of the central shaft 32 and is engaged with the screw 37 of the first motor 36, where the central shaft 32 is disposed generally horizontally, so that the underside of the screw 37 is engaged with the upper side of the gear 310.

Here, two drive bevel gears 31 are located on both axial sides of the gear 310, more precisely, two drive bevel gears 31 are provided on both ends of the central shaft 32, and have tapered shapes respectively tapered away from the gear 310. At least one pair of driven bevel gears 33 are respectively coaxially fixedly mounted to end portions of both connecting shafts 311 of a pair of brushes 12 accommodated in the frame 34, which protrude through the first frame 343, and respectively engage with the corresponding drive bevel gears 31.
In addition, as shown in fig. 2, the driving unit 10 may further include a base 38, the base 38 having two side plates 381 and a bottom plate 382. The central shaft 32 is rotatably connected to both side plates 381 of the base 38, and both side plates 381 may be interposed between the gear 310 and a corresponding one of the drive bevel gears 31, respectively. And, the bottom plate 382 of the base 38 is fixedly coupled to the upper surface of the first frame 343.
It should be noted that the above-described drive unit 10 including the central shaft 32, the gear 310, the at least one pair of drive bevel gears 31, and the at least one pair of driven bevel gears 33 is only one example illustrated for better implementation of the present invention. The present invention is not limited thereto as long as the driving unit 10 can transmit the torque of the first motor 36 to the two connection shafts 311 to rotate them toward the middle. In addition, the brushes 12 are not limited to one pair, and in other examples, a plurality of pairs of brushes 12 may be provided, and each pair of brushes 12 is driven by the first motor 36 to rotate toward the middle.
By mounting the cleaning mechanism 3 on the radiation plate 1, the first motor 36 is started to operate, and the first motor 36 rotates the screw 37, whereby the screw 37 transmits power (torque) to the gear 310. The gears 310 rotate while driving the central shaft 32 to rotate, so that the drive bevel gears 31 at both ends respectively rotate, and two driven bevel gears 33 engaged at the lower sides of the drive bevel gears 31 obtain power. The driven bevel gears 33 at both sides drive the corresponding connecting shafts 311 to rotate, and a plurality of single bristle pieces 39 are uniformly distributed on the outer surfaces of the connecting shafts 311. The thickness of the plurality of flexible bristles 392 on the plurality of single bristle pieces 39 is equal to or slightly smaller than the gap between the two sheets 11 (see fig. 1) of the heat dissipation plate 1, so that the flexible bristles 392 can clean dust in the gap between the two sheets 11 of the heat dissipation plate 1, and the connecting rods 391 (arc-shaped rods) on two sides are driven by the corresponding connecting shafts 311, so that the flexible bristles 392 clean the gap between the sheets 11 of the heat dissipation plate 1. One driven bevel gear 33 rotates clockwise, and the other driven bevel gear 33 rotates anticlockwise, so that the two connecting shafts 311 rotate reversely, and finally the plurality of single bristle pieces 39 on the two connecting shafts 311 gather dust in gaps between sheets 11 of the heat dissipation plate 1 to the middle, so that the cleanliness of the heat dissipation plate 1 is improved, and efficient heat dissipation performance is guaranteed.
The dust suction mechanism 5 and the receiving mechanism 4 of the computer radiation plate cleaning apparatus 100 according to the embodiment of the present invention will now be described with reference to fig. 1, 2, 3, 5, and 6.
As shown in fig. 1 and 5, the dust collection mechanism 5 is connected to the second side 342 of the cleaning mechanism 3. The dust suction mechanism 5 includes a second motor 54, an impeller 53, and a dust suction bin 51. As shown in fig. 5, the impeller 53 has a hollow shaft portion 531 and a blade 533 surrounding the hollow middle portion 531. The first port 532 of the hollow shaft portion 531 is for connection to an opening 351 (fig. 3) of the housing 35 of the cleaning mechanism 3 and is in air communication with the opening 351. The second motor 54 is fixedly installed inside the other port (not shown) of the hollow shaft portion 531 of the impeller 53 and drives the impeller 53 to rotate.
As shown in fig. 5, the suction bin 51 surrounds (overlaps) the outside of the impeller 53 and has an inlet 511 and an outlet 512. The inlet 511 surrounds the first port 532 of the hollow shaft portion 531 of the impeller 53, and the outlet 512 is located on the downstream side, i.e., the air outlet side, of the blades 533 of the impeller 53. In addition, although not shown in the drawings, in this example, a movable shaft (output shaft) portion of the second motor 54 is rotatably connected to the inside of one side of the suction hopper 51 (in the drawing, a second port opposite to the first port 532 of the hollow shaft portion 531 of the impeller 53) so that an air flow from the first port 532 of the hollow shaft portion 531 of the impeller 53 to the outlet 512 of the suction hopper 51 is generated in the inner chamber 513 of the suction hopper 51 when the second motor 54 is started.
Further, a seal ring 52 is provided between the inlet 511 of the suction hopper 51 and the first port 532 of the hollow shaft portion 531 of the impeller 5. The sealing ring 52 is attached to the suction bin 51, for example rotatably around the inlet 511. In an alternative example, the underside of the suction bin 51 may be fixedly connected to the bracket 55, and a portion of the upper side of the bracket 55 is fixedly connected to the underside of the second motor 54.
Referring to fig. 1 and to fig. 5 and 6, the receiving means 4 is installed at the outlet 512 side of the dust collecting means 5 for collecting dust, and thus may also be referred to as dust collecting means. The receiving means 4 may have an inlet 421 in air communication with the outlet 512 of the suction hopper 51 and an outlet 422 for exhausting air, in the present example shown in fig. 6, the receiving means 4 may for example comprise a fixed hopper 42 and a movable hopper 43, and the inlet 421 and the outlet 422 are provided on the fixed hopper 42. The stationary bin 42 is fixedly connected to the suction bin 51, and an inlet 421 of the stationary bin 42 is in air communication with an outlet 512 of the suction bin 51, and an outlet 422 of the stationary bin 42 is in communication with the ambient environment via the filter screen 41. The movable compartment 43 is removably nested in the inner wall of the fixed compartment 42 and has an inlet 431 and an outlet 432 corresponding to the inlet 421 and outlet 422, respectively, of the fixed compartment 42. Preferably, the inlet 421 and the outlet 422 of the fixed bin 42 may be disposed opposite to each other at upper positions of two opposite sidewalls of the fixed bin 42. Therefore, the movable chamber 43 may be provided with an inlet 431 and an outlet 432 corresponding to the inlet 421 and the outlet 422 of the fixed chamber 42, respectively, and the outlet 432 of the movable chamber 43 may overlap with the inner side of the filter screen 41. Preferably, a pull ring 44 may be fixedly attached to the movable housing 43, for example, on an upper surface of the movable housing 43, so as to facilitate pulling out the movable housing 43.
As will be appreciated by those skilled in the art, the above-described receiving mechanism 4 comprising a fixed bin 42 and a movable bin 43 is only one specific example of the present invention. In practice, it is possible to include only the fixed bin 42 or only the movable bin 43.
By activating the first motor 36 and simultaneously activating the second motor 54, the second motor 54 drives the impeller 53 to rotate within the interior 513 of the suction bin 51. A suction force is generated in the middle of the impeller 53 such that an air flow is generated in the inner chamber 513 of the suction bin 51 from the first port 532 of the hollow shaft 531 of the impeller 53 to the outlet 512 of the suction bin 51. Since the dust collection bin 51 is in air communication with the housing 35 of the cleaning mechanism 3 forming part of the structure (frame 34 and housing 35) surrounding the two brushes 12, dust cleaned and gathered by the rotation of the plurality of individual bristle members 39 on the two brushes 12 toward each other is caused to pass through the housing 35 (conical shell) under the action of suction force, enter the middle part of the sealing ring 52 via the outlet 351 (fig. 3), and enter the inside of the fixed bin 42 through the outlet 512 of the dust collection bin 51 under the rotation assistance of the sealing ring 52. Under the filtering of the filter screen 41, air is discharged from the filter screen 41 to the surrounding environment. Dust in the air is filtered and falls into the movable compartment 43. The pull ring 44 can be pulled upwards periodically to take the movable bin 43 out of the fixed bin 42 for cleaning, thereby quickly collecting dust and facilitating cleaning.
As mentioned above, it is preferred that the cleaning device 100 may further comprise a securing mechanism 2. The fixing mechanism 2 is described below with reference to fig. 1 and 7.
As shown in fig. 1, generally, the fixing mechanism 2 is provided on the cleaning mechanism 3 for fixing the cleaning mechanism 3 to the radiation plate 1. The fixing mechanism 2 may include two or more. In the example shown in fig. 1, since the frame 34 of the cleaning mechanism 3 is larger than the radiation plate 1 by one turn, the radiation plate 1 can be clamped to the first side 341 of the frame 34 of the cleaning mechanism 3. Therefore, two fixing mechanisms 2 are provided only on the first frame 343 on the upper side of the frame 34.
The specific structure of the fixing mechanism 2 will be described below with specific reference to fig. 7. The fixing mechanism 2 comprises a connecting ring frame 23, a first threaded rod 22 and a second threaded rod 24. The link ring frame 23 has a first end 231 and a second end 232, and internal threads 233, 234 provided in the axial direction of the link ring frame 23 are provided inside the both ends, respectively. The outer surface of the first end 221 of the first threaded rod 22 is provided with an external thread 223 and is screwed with the internal thread 233 of the first end 231 of the connection ring frame 23 by means of this external thread 223. A fastening feeler 21 is connected to the second end 222 of the first threaded rod 22, which fastening feeler 21 protrudes downwards in the radial direction of the connecting ring frame 23.
It is noted that the fastening feeler 21 may be directly fixedly attached to the second end 222 of the first threaded rod 22, or may be rotatably attached to the second end 222 of the first threaded rod 22 by means of, for example, a shaft. In the latter case, the fastening tab 21 needs to be able to be fixed in a rotated state to achieve the effect of sandwiching the heat dissipation plate 1.
The outer surface of the first end 241 of the second threaded rod 24 is provided with an external thread 243 and is screwed with the internal thread 234 of the second end 232 of the connection ring frame 23 by means of this external thread 243. The second end 242 of the second threaded rod 24 is rotatably connected to the fixed block 25 via the movable shaft 26. The fixing block 25 is fixedly mounted to the frame 34 of the cleaning mechanism 3 as shown in fig. 1, and in this example the fixing block 25 is fixed to the upper surface of the first frame 343 (fig. 1 and 2) of the cleaning mechanism 3, and one end of the fixing mechanism 2 having the fastening feeler 21 protrudes from the first side 341 of the frame 34, so that when the connection ring frame 23 is rotated, the fastening feeler 21 moves toward the first side 341 to be able to clamp the heat radiation plate 1 to the cleaning mechanism 3.
The radiator plate 1 is clamped into the middle of the frame 34 by placing the upper side of the cleaning mechanism 3 (i.e., the upper surface of the first frame 343) in parallel with the upper side of the radiator plate 1. The fastening tab 21 is rotatably mounted in this example, and thus the fastening tab 21 is adjusted to a vertically downward state (as shown in fig. 1), i.e., a state protruding downward in the radial direction of the connection ring frame 23. Then, the connection ring frame 23 is rotated, the rotation of the connection ring frame 23 causes the first threaded rod 22 and the second threaded rod 24 respectively positioned at both ends of the connection ring frame 23 to have a tendency to approach toward the middle of the connection ring frame 23, but since the second threaded rod 24 is restricted by the fixed block 25 and the movable shaft 26, the position is not moved, so that the first threaded rod 22 is contracted toward the cleaning mechanism 3, thereby clamping the fastening tentacle 21 at the other side of the heat dissipation plate 1, thereby mounting the computer heat dissipation plate cleaning device 100 according to the embodiment of the present invention on the heat dissipation plate 1, thereby facilitating the subsequent cleaning work.
Referring to fig. 1 to 7, a method for using the computer heat sink cleaning apparatus 100 and an operation principle according to an embodiment of the present invention are described. First, the upper side of the cleaning mechanism 3 (the upper surface of the first frame plate 343 of the frame 34) is placed in parallel with the upper side of the heat sink 1, the heat sink 1 is engaged into the middle of the frame 34, the fastening feeler 21 is adjusted to be in a vertically downward state, and then the connection ring frame 23 is shifted (rotated). The rotation of the connection ring frame 23 makes the first threaded rod 22 and the second threaded rod 24 respectively positioned at both ends of the connection ring frame 23 have a tendency to approach toward the middle of the connection ring frame 23, but since the second threaded rod 24 is restricted by the fixed block 25 and the movable shaft 26, the position is not moved, so that the first threaded rod 22 is contracted toward the cleaning mechanism 3, so that the fastening tentacles 21 are caught at the other side of the heat radiation plate 1, thereby mounting the present device 100 on the heat radiation plate 1.
The first motor 36 is started to operate, and the first motor 36 drives the screw 37 to rotate, so that the screw 37 transmits power to the gear 310. The gears 310 rotate while driving the central shaft 32 to rotate, so that the drive bevel gears 31 at both ends respectively rotate, and two driven bevel gears 33 engaged at the lower sides of the drive bevel gears 31 obtain power. The driven bevel gear 33 drives the two connecting shafts 311 of the two brushes 12 to rotate. The outer surface of each connecting shaft 311 is uniformly distributed with a plurality of individual bristle pieces 39, and the thickness of the plurality of tough bristles 392 on the plurality of individual bristle pieces 39 is equal to or slightly smaller than the gap between the two sheets 11 (see fig. 1) of the heat dissipation plate 1, so that the tough bristles 392 can clean dust in the gap between the two sheets 11 of the heat dissipation plate 1. The two connecting rods 391 (arc-shaped rods) are driven by the corresponding connecting shafts 311, and the flexible bristles 392 can clean dust in the gap between the sheets 11 of the heat dissipation plate 1. One driven bevel gear 33 rotates clockwise and the other driven bevel gear 33 rotates counterclockwise, resulting in the two coupling shafts 311 also rotating toward each other, and finally the respective pluralities of individual bristle pieces 39 on the two coupling shafts 311 gather dust in the gaps between the sheets 11 of the heat dissipation plate 1 toward the middle.
The second motor 54 is started simultaneously with the first motor 36, and the second motor 54 drives the impeller 53 to rotate in the inner cavity 513 of the dust collection bin 51. A suction force is generated in the middle of the impeller 53 such that an air flow is generated in the inner chamber 513 of the suction bin 51 from the first port 532 of the hollow shaft 531 of the impeller 53 to the outlet 512 of the suction bin 51. Since the dust collection bin 51 is in air communication with the housing 35 of the cleaning mechanism 3 forming part of the structure (frame 34 and housing 35) surrounding the two brushes 12, dust cleaned and gathered by the rotation of the plurality of individual bristle members 39 on the two brushes 12 toward each other is caused to pass through the housing 35 (conical shell) under the action of suction force, enter the middle part of the sealing ring 52 via the outlet 351 (fig. 3), and enter the inside of the fixed bin 42 through the outlet 512 of the dust collection bin 51 under the rotation assistance of the sealing ring 52. Under the filtering of the filter screen 41, air is discharged from the filter screen 41 to the surrounding environment. Dust in the air is filtered and falls into the movable compartment 43. The pull ring 44 can be pulled upwards periodically, and the movable bin 43 is taken out from the fixed bin 42 for cleaning, so that dust can be collected quickly and cleaning is convenient.

step S202 of dust collection: the second motor 54 is activated to generate an air flow in the interior chamber 513 of the suction bin 51 from the first port 532 of the hollow shaft portion 531 of the impeller 53 to the outlet 512 of the suction bin 51 to draw dust collected and cleaned by the two sets of bristle assemblies 312 into the receptacle 4 via the opening 351 of the housing 35 surrounding at least one pair of brushes 12, the hollow shaft portion 531 of the impeller 53, the blades of the impeller 53 and the outlet 512 of the suction bin 51.
