Description

Technical Field

[0001] This invention relates to the field of cleaning and rust removal equipment technology, and in particular to a device for cleaning and removing rust from the bottom bracket of bicycle parts. Background Technology

[0002] The bottom bracket of a bicycle is an important component installed at the bottom bracket of the bicycle. It is used to connect the rotating parts of the left and right cranks and is crucial for supporting the rotation of the chainring and crank assembly and reducing the coefficient of friction. After a period of use, the bottom bracket will show signs of rust. To extend the life of the bottom bracket, it needs to be removed for cleaning and rust removal. To save manpower, an ultrasonic cleaner is usually used for cleaning and rust removal of the bottom bracket.

[0003] When using traditional ultrasonic cleaners to clean and remove rust from bicycle bottom brackets, although these machines have a circulating filtration system that filters impurities from the cleaning solution through a screen to ensure the cleanliness of the cleaning solution inside the tank, after prolonged use, a large amount of debris easily accumulates on the surface of the filter screen, affecting its filtration efficiency. Furthermore, cleaning the filter screen requires manual intervention, reducing the convenience of using the ultrasonic cleaner. Additionally, the top cover of traditional ultrasonic cleaners must be manually opened and closed; if users are holding items, they must put those items down before opening or closing the cover, further reducing the practicality of the ultrasonic cleaner. Summary of the Invention

[0004] This disclosure relates to a device for cleaning and removing rust from the bottom bracket of bicycle parts. Through the inclusion of a flow meter and an automatic unclogging mechanism, the flow meter measures the flow rate of the cleaning fluid during the delivery of the cleaning fluid by the pump. When the flow rate is low, the unclogging motor is activated, ultimately moving the unclogging brush back and forth to remove a large amount of debris adhering to the right surface of the filter screen, thus preventing any impact on the filter's filtration efficiency. Furthermore, cleaning the filter screen surface requires no manual intervention, improving the ease of use of this cleaning and rust removal device. The combination of a foot pedal mechanism and a drive assembly allows the top cover to be closed without manual operation, enabling users to open and close the top cover without first putting down items, further enhancing the practicality of this cleaning and rust removal device.

[0014] This invention provides a device for cleaning and removing rust from the bottom bracket of bicycle parts, which has the following beneficial effects:

[0015] 1. By incorporating a flow meter and an automatic unclogging mechanism, the flow rate of the cleaning fluid can be measured during the delivery of the cleaning fluid by the infusion pump. When the flow rate of the cleaning fluid is low, the unclogging motor is started. The rotating shaft of the unclogging motor drives the first bevel gear, the second bevel gear, the vertical rotating shaft, and the drive disc to rotate. Then, the rotating drive disc drives the actuating column to rotate. Subsequently, the rotating actuating column drives the drive frame and the unclogging brush to move back and forth, thereby sweeping away a large amount of debris attached to the right surface of the filter screen, avoiding affecting the filtration effect of the filter screen. Moreover, no manual cleaning is required when cleaning the debris on the surface of the filter screen, thus improving the convenience of using this cleaning and rust removal device.

[0016] 2. Through the cooperation of the foot pedal mechanism and the drive component, when it is necessary to close the top cover, stepping on the right-side pedal will press the button on the right-side push switch, thereby controlling the drive component to close the top cover. When it is necessary to open the top cover, simply stepping on the left-side pedal will do the same. This eliminates the need for manual operation, and people can open and close the top cover without having to put down their items first, thus improving the practicality of this cleaning and rust removal device.

[0017] 3. Through the coordination of the pull rope, the drive plate, and the sweeping mechanism, the two sweeping brushes can be moved downwards when either pedal is stepped on. When the foot is removed from the pedal, the two sweeping brushes move upwards back to their original position under the elastic force of the external spring of the drive rod. The two sweeping brushes, which move up and down, remove dust and other debris attached to the heat dissipation holes on the right side of the ultrasonic generator, thus avoiding affecting the ventilation effect of the heat dissipation holes on the right side of the ultrasonic generator and the heat dissipation effect of the internal electrical components of the ultrasonic generator, thereby improving the service life of the internal electrical components of the ultrasonic generator.

[0047] When the sealing cover 301 is fixedly installed on the upper part of the filter box 3, the bristles of the cleaning brush 806 are in close contact with the right surface of the filter screen 304.

[0048] Example 2, based on Example 1, such as Figure 1 , Figure 8 and Figure 9 As shown, the sweeping mechanism 7 includes two sweeping brushes 701, four driving rods 702, a synchronization plate 703, and a pull rope 704. Two sweeping brushes 701 are used, and four driving rods 702 are fixedly connected to each brush 701. The lower ends of the four driving rods 702 are fixedly connected to the synchronization plate 703. The four driving rods 702 are slidably connected to the right side of the support platform 102, and each driving rod 702 is fitted with a spring on its outer surface above the support platform 102. The bristles of both sweeping brushes 701 are in close contact with the heat dissipation holes on the right side of the ultrasonic generator 4. The synchronization plate 703... A pull rope 704 is fixedly connected to the bottom end face of the 3, and the other end of the pull rope 704 is fixedly connected to the upper end face of the drive plate 603. Through the cooperation of the pull rope 609, the drive plate 603 and the sweeping mechanism 7, when either pedal 602 is stepped on, the two sweeping brushes 701 can be moved downward. When the foot is removed from the pedal 602, the two sweeping brushes 701 move upward back to their original position under the action of the spring force outside the drive rod 702. The dust and other debris attached to the heat dissipation hole on the right side of the ultrasonic generator 4 are swept away by the two sweeping brushes 701 that move up and down.

[0049] The working principle of this embodiment is as follows: When in use, cleaning fluid is added to the cleaning tank on the main body 2 of the ultrasonic cleaner. Then, the bicycle bottom bracket is placed inside the cleaning tank on the main body 2 of the ultrasonic cleaner. Next, the right pedal 602 is stepped on by foot, causing the pedal 602 to move downward, thereby pressing the button on the right push switch 607. Then, the controller 208 controls the extension rod of the electric cylinder 501 to extend, which moves the synchronizing rod 502 and the two drive racks 503 upward in a straight line. Then, the two drive racks 503 moving upward in a straight line drive the two gears 203, the rotating shaft 201 and the top cover 202 to rotate counterclockwise. When the extension rod of the electric cylinder 501 extends upward to the limit position, the top cover 202 rotates counterclockwise to close. When it is necessary to open the top cover 202, it can be done by stepping on the left pedal 602 by foot.

[0050] After the top cover 202 is closed, the ultrasonic generator 4 is started. The ultrasonic generator 4 drives the vibrator on the main body 2 of the ultrasonic cleaner to operate through the high-frequency electrical signal, generating ultrasonic waves. The ultrasonic waves are transmitted to the cleaning fluid through the cleaning tank on the main body 2 of the ultrasonic cleaner, and finally transmitted to the surface of the bicycle bottom bracket through the ultrasonic waves in the cleaning fluid, thereby achieving the cleaning and rust removal effect.

[0051] When it is necessary to filter impurities in the cleaning solution, simply start the infusion pump 207 to create negative pressure inside the filter box 3 and the infusion pipe 204, thereby drawing the cleaning solution from the cleaning tank on the main body 2 of the ultrasonic cleaner into the filter box 3. The impurities in the cleaning solution are filtered through the filter screen 304 inside the collection box 302. The filtered impurities remain inside the collection box 302, while the filtered cleaning solution returns to the cleaning tank on the main body 2 of the ultrasonic cleaner through the return pipe 205. This cycle is repeated to achieve the filtration of the cleaning solution.

[0052] During the delivery of cleaning fluid by the infusion pump 207, the flow rate of the cleaning fluid is measured by the flow meter 206. When the flow rate of the cleaning fluid is low, it can be known that there are many impurities on the surface of the filter screen 304 inside the collection box 302. Then, the unblocking motor 801 is started. The rotating shaft of the unblocking motor 801 drives the first bevel gear, the second bevel gear, the vertical rotating shaft 802 and the drive disk 804 to rotate. Then, the rotating drive disk 804 drives the actuating column 808 to rotate. Then, the rotating actuating column 808 drives the drive frame 807 and the unblocking brush 806 to move back and forth, thereby sweeping away a large amount of impurities attached to the right surface of the filter screen 304 and avoiding affecting the filtration effect of the filter screen 304.

[0053] When either pedal 602 is stepped on, the pedal 602 will move downward via the pull rope 609, which will drive the drive plate 603, pull rope 704, synchronization plate 703, drive rod 702, and two cleaning brushes 701. When the foot is removed from the pedal 602, the two cleaning brushes 701 will move upward back to their original position under the action of the spring force outside the drive rod 702. The two cleaning brushes 701, which move up and down, will remove dust and other debris attached to the heat dissipation holes on the right side of the ultrasonic generator 4, thus avoiding affecting the ventilation effect of the heat dissipation holes on the right side of the ultrasonic generator 4.
