Description

Technical Field

[0001] This utility model belongs to the field of fin cleaning technology, and in particular relates to an engine cooling fin cleaning device. Background Technology

[0002] Heat sinks, or simply heat sinks, are classified as "passive heat dissipation components" in the field of electronic engineering design. They are made of metals with good thermal conductivity, light weight, and easy processing, which are attached to the heat-generating surface and dissipate heat through a composite heat exchange mode. As the usage time increases, dust will accumulate on the outer surface of the heat sinks, so they need to be cleaned regularly.

[0003] A Chinese patent discloses a dust cleaning device for finned radiators, including a vacuum cleaner. A suction pipe is connected to the suction port of the vacuum cleaner, and a connecting pipe is provided at the other end of the suction pipe. A suction head is provided at the other end of the connecting pipe. A connecting frame is provided on one side of the outer ring of the suction head, and a heat sink fin brush head is connected to one side of the connecting frame via a snap-fit ​​mechanism. Multiple sets of bristles are provided on one side of the heat sink fin brush head. This dust cleaning device for finned radiators, by including the heat sink fin brush head, suction head, and bristles, can clean dust from the narrow spaces between the heat sink fins. The vacuum cleaner, connecting pipe, and heat sink fin brush head can suck up the brushed dust, preventing dust from the finned radiator from being dispersed into the air and inhaled by personnel. The connecting frame, snap-fit ​​mechanism, and push plate allow for easy replacement of the heat sink fin brush head. Most current cleaning devices use air guns to clean the dust off the outer surface of the cooling fins. This method causes dust to fly around and pollute the environment. Therefore, an engine cooling fin cleaning device is provided. Utility Model Content

[0004] The purpose of this utility model is to provide an engine cooling fin cleaning device to solve the problem of dust flying around in the current cleaning methods.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an engine cooling fin cleaning device, comprising a cleaning box, wherein ash discharge ports are provided on both side walls of the cleaning box, a cleaning component is provided on the inner side wall of the cleaning box, and a limiting component is provided on the inner wall of the shell cavity of the cleaning box;

[0006] The cleaning assembly includes a drive motor, which is fixedly connected to the side wall of the cleaning box via a mounting cover. A rotating rod is fixedly mounted on the output end of the drive motor, and a rotating disk is fixedly mounted on the outer surface of the rotating rod.

[0007] As a further description of the above technical solution:

[0008] Several top blocks are fixedly installed on the outer surface of the rotating disk, and a collection frame is fixedly installed on the inner side wall of the cleaning box. Slots are provided on both sides of the collection frame, and the slots are aligned with the ash discharge port.

[0009] As a further description of the above technical solution:

[0010] A telescopic spring is fixedly installed on the lower surface of the collection frame. A fixing plate is fixedly installed on one end of the telescopic spring. A protrusion is fixedly installed on the lower surface of the fixing plate. An impact rod is fixedly installed on the upper surface of the fixing plate. One end of the impact rod passes through the interior of the telescopic spring.

[0011] As a further description of the above technical solution:

[0012] A reciprocating screw is rotatably mounted on the inner wall of the cleaning box. A toothed sprocket is fixedly mounted on the outer surface of the reciprocating screw and the outer surface of the rotating rod. The toothed sprockets are connected by a toothed chain drive. One end of the reciprocating screw extends into the interior of the collection frame. A scraper is threaded onto the outer surface of the reciprocating screw, and the lower surface of the scraper is in contact with the bottom surface of the collection frame.

[0013] As a further description of the above technical solution:

[0014] The limiting component includes a partition plate, the outer surface of which is fixedly connected to the inner wall of the cleaning box cavity. A threaded rod is rotatably mounted on the upper surface of the partition plate, one end of which extends to the outer surface of the cleaning box, and a threaded sleeve is threadedly mounted on the outer surface of the threaded rod.

[0015] As a further description of the above technical solution:

[0016] A limiting rod is fixedly installed on the outer surface of the threaded sleeve. A stroke groove is provided on the inner surface of the cleaning box. One end of the limiting rod extends into the interior of the cleaning box through the stroke groove. A mounting bracket is fixedly installed on the lower surface of the limiting rod. A stop bar is rotatably installed on the inner wall of the mounting bracket via a rotating shaft. A return spring is fixedly installed on the upper surface of the stop bar. One end of the return spring is fixedly connected to the inner wall of the top surface of the mounting bracket.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0018] 1. In this utility model, a cleaning component is provided. The drive motor drives the rotating rod to rotate, which in turn drives the rotating disk to rotate the top block synchronously. Under the action of the protrusion, the impact rod moves up and down under the action of the telescopic spring. At this time, the impact rod will impact the collection frame, causing the collection frame to vibrate the heat sink fins. When the heat sink fins vibrate, the dust attached to the heat sink fins will be shaken off into the collection frame. Under the action of the toothed sprocket and toothed chain, the reciprocating screw will rotate. Under the action of the thread, the scraper will move back and forth in the collection frame, thereby pushing the dust in the collection frame towards the slot, and then discharging it out of the cleaning box through the ash discharge port. During the cleaning process, the dust is automatically collected and discharged. Compared with the method of using an air gun to blow, it can avoid dust flying around and causing dust pollution to the environment, and it can also maintain the cleanliness of the cleaning device.

[0019] 2. In this utility model, by setting a limiting component, the heat dissipation fins are placed on the collection frame inside the cleaning box. Then, the threaded rod rotates on the upper surface of the partition. At this time, under the action of the thread, the threaded sleeve will drive the limiting rod to descend. Since the limit rod blocks the upward movement of the stop rod, the heat dissipation fins will be fixed on the collection frame under the action of the stop rod. After the heat dissipation fins are cleaned, the stop rod is moved up a distance. Since there is no obstruction when the stop rod rotates downward, it will lose its obstruction to the heat dissipation fins. Then, the heat dissipation fins are taken out. This avoids the heat dissipation fins shaking too much during the cleaning process, which would cause the vibration frequency to drop and the cleaning effect to decrease. This improves the cleaning effect and practicality of the cleaning device. Attached Figure Description

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-4 This utility model provides a technical solution: an engine cooling fin cleaning device, including a cleaning box 1, with ash discharge ports 4 on both side walls of the cleaning box 1, a cleaning component 2 on the inner side wall of the cleaning box 1, and a limiting component 3 on the inner wall of the shell cavity of the cleaning box 1.

[0028] The cleaning assembly 2 includes a drive motor 21, which is fixedly connected to the side wall of the cleaning box 1 via a mounting cover. A rotating rod 22 is fixedly mounted on the output end of the drive motor 21. A rotating disk 27 is fixedly mounted on the outer surface of the rotating rod 22. Several top blocks 28 are fixedly mounted on the outer surface of the rotating disk 27. A collection frame 23 is fixedly mounted on the inner side wall of the cleaning box 1. Slots are provided on both side walls of the collection frame 23, and the slots are aligned with the ash discharge port 4. A telescopic spring 29 is fixedly mounted on the lower surface of the collection frame 23. A fixing plate 210 is fixedly mounted on one end of the telescopic spring 29. A protrusion 212 is fixedly installed on the lower surface of the fixed plate 210, and an impact rod 211 is fixedly installed on the upper surface of the fixed plate 210. One end of the impact rod 211 passes through the interior of the telescopic spring 29. A reciprocating screw 24 is rotatably installed on the inner wall of the cavity of the cleaning box 1. A toothed sprocket 25 is fixedly installed on the outer surface of the reciprocating screw 24 and the outer surface of the rotating rod 22. The toothed sprockets 25 are connected to each other by a toothed chain drive. One end of the reciprocating screw 24 extends into the interior of the collection frame 23. A scraper 26 is threaded on the outer surface of the reciprocating screw 24. The lower surface of the scraper 26 is in contact with the bottom surface of the collection frame 23.

[0029] The specific implementation method is as follows: the drive motor 21 drives the rotating rod 22 to rotate, thereby driving the rotating disk 27 to rotate and causing the top block 28 to rotate synchronously. Under the action of the protrusion 212, the impact rod 211 moves up and down under the action of the telescopic spring 29. At this time, the impact rod 211 will impact the collection frame 23, thereby causing the collection frame 23 to vibrate the heat sink fins. When the heat sink fins vibrate, the dust attached to the heat sink fins will be shaken off into the collection frame 23. Under the action of the toothed sprocket 25 and the toothed chain, the reciprocating screw 24 will rotate. Under the action of the thread, the scraper 26 will move back and forth in the collection frame 23, thereby pushing the dust in the collection frame 23 towards the slot, and then discharging it out of the cleaning box 1 through the ash discharge port 4.

[0030] The limiting component 3 includes a partition 31. The outer surface of the partition 31 is fixedly connected to the inner wall of the cavity of the cleaning box 1. A threaded rod 32 is rotatably mounted on the upper surface of the partition 31. One end of the threaded rod 32 extends to the outside of the upper surface of the cleaning box 1. A threaded sleeve 33 is threadedly mounted on the outer surface of the threaded rod 32. A limiting rod 34 is fixedly mounted on the outer surface of the threaded sleeve 33. A stroke groove is provided on the inner surface of the cleaning box 1. One end of the limiting rod 34 extends into the interior of the cleaning box 1 through the stroke groove. A mounting bracket 35 is fixedly mounted on the lower surface of the limiting rod 34. A stop rod 36 is rotatably mounted on the inner wall of the mounting bracket 35 via a rotating shaft. A return spring 37 is fixedly mounted on the upper surface of the stop rod 36. One end of the return spring 37 is fixedly connected to the inner wall of the top surface of the mounting bracket 35.

[0031] The specific implementation method is as follows: Place the heat dissipation fins on the collection frame 23 inside the cleaning box 1, and then rotate the threaded rod 32 on the upper surface of the partition 31. At this time, under the action of the thread, the threaded sleeve 33 will drive the limiting rod 34 to descend. Since the stop rod 36 is blocked by the limiting rod 34 when it tilts upward, the heat dissipation fins will be fixed on the collection frame 23 under the action of the stop rod 36. After the heat dissipation fins are cleaned, move the stop rod 36 up a distance. Since there is no obstruction when the stop rod 36 rotates downward, the stop rod 36 will lose its obstruction to the heat dissipation fins after it moves downward. Then, the heat dissipation fins are taken out.

[0032] Working principle: The heat dissipation fins are placed on the collection frame 23 inside the cleaning box 1. Then, the threaded rod 32 rotates on the upper surface of the partition 31. At this time, the threaded sleeve 33 will cause the limiting rod 34 to descend under the action of the thread. Since the stop rod 36 is blocked by the limiting rod 34 when it tilts upward, the heat dissipation fins will be fixed on the collection frame 23 under the action of the stop rod 36. The drive motor 21 drives the rotating rod 22 to rotate, thereby driving the rotating disk 27 to rotate and causing the top block 28 to rotate synchronously. Under the action of the protrusion 212, the impact rod 211 will move up and down under the action of the telescopic spring 29. At this time, the impact rod 211 will impact the top block 28. The collection frame 23 is impacted, causing the heat sink fins to vibrate. When the heat sink fins vibrate, the dust attached to the heat sink fins is shaken off into the collection frame 23. Under the action of the toothed sprocket 25 and the toothed chain, the reciprocating screw 24 is rotated. Under the action of the thread, the scraper 26 moves back and forth in the collection frame 23, thereby pushing the dust in the collection frame 23 towards the slot, and then discharges it through the dust discharge port 4 into the cleaning box 1. After the heat sink fins are cleaned, the baffle 36 is moved up a distance. Since there is no obstruction when the baffle 36 rotates downward, the baffle 36 will lose its obstruction to the heat sink fins after it moves downward, and then the heat sink fins are removed.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
