A second heat dissipation hole 12 is opened on the side of the fixed cylinder 2 near the outside, which is connected to the rotating cavity 11 and the first heat dissipation holes 10. A third heat dissipation hole 13 is opened on the side of the fixed cylinder 2 near the battery 39, which is connected to the rotating cavity 11 and the surrounding area of ​​the battery 39. The filter cylinder 4 is inserted into the inner wall of the rotating cavity 11, and the filter cylinder 4 can rotate inside the rotating cavity 11.

[0021] The partition 8 includes a rubber ring 14 installed inside the fixed cylinder 2. The fixed cylinder 2 has an annular cavity 15 that communicates with the rotating cavity 11. The upper and lower sides of the rubber ring 14 are fixedly connected to the annular cavity 15. The side of the rubber ring 14 can abut against the inner wall of the filter cylinder 4.

One end of the control block 17 is fixedly connected to a tension spring 19 that is fixedly connected to the control groove 18. The control grooves 18 and the annular cavity 15 are used to store hydraulic oil.

[0023] The heat dissipation mechanism also includes a fixing ring 20 fixedly installed above the first impeller 5. Multiple sets of device slots 21 are evenly opened on the fixing ring 20. A drive block 22 is slidably connected in the device slot 21. One end of the drive block 22 can abut against the inner wall of the filter cylinder 4. A first spring 23 fixedly connected to the device slot 21 is fixedly connected to the side of the drive block 22. A centrifugal block 24 is slidably connected in the device slot 21. A connecting rope 25 fixedly connected to the centrifugal block 24 is fixedly connected to the drive block 22.

[0024] The base 1 is provided with a drive component 26 for driving the connecting ring 7 to rotate. The drive component 26 includes a drive motor 33 fixedly installed on the base 1. The drive motor 33 is preferably a YYHS-40 model. The output end of the drive motor 33 is coaxially fixedly connected to a drive gear 34. An internal gear ring 35 is fixedly connected to the connecting ring 7. The internal gear ring 35 meshes with the drive gear 34. The rotating cylinder 9 is provided with an adjustment component 27 for driving the rotating cylinder 9 to rotate and adjusting the position of the first heat dissipation hole 10 during the rotation of the second impeller 6.

[0025] The adjusting component 27 includes multiple sets of fixing frames 28 fixedly installed on the inner wall of the rotating cylinder 9. The bottom of the fixing cylinder 2 is provided with a rotating groove 29. Both sides of the fixing frame 28 are respectively fixedly connected with elastic ropes 30 that are fixedly connected to the side wall of the rotating groove 29. A friction block 31 is slidably connected in the horizontal direction inside the fixing frame 28. A second spring 32 fixedly connected to the side of the friction block 31 is fixedly connected to the fixing frame 28. The end of the friction block 31 away from the second spring 32 can rub against the outer wall of the second impeller 6.

[0026] In this embodiment, opening the top cover 38 allows the battery 39 to be placed on the shock-absorbing platform 36 above the base 1. The battery 39 is then fixed by the surrounding fixing brackets 37. Closing the top cover 38 completes the loading of the battery 39. When auxiliary heat dissipation is required, the drive motor 33 is started to drive the drive gear 34 to rotate. The drive gear 34 drives the internal gear ring 35 to rotate the connecting ring 7. The connecting ring 7 drives the first impeller 5 and the second impeller 6 on the upper and lower sides to rotate synchronously. The outer edge of the second impeller 6 drives the friction block 31 to rotate the rotating cylinder 9 by a certain angle until the fixing frame 28 reaches a position close to the rotating groove 29. At this time, the first heat dissipation hole 10 rotates to a position connected to the second heat dissipation hole 12. Since the blades on the first impeller 5 and the second impeller 6 have opposite tilt angles, the air inlet and outlet directions on the upper and lower sides of the filter cylinder 4 are opposite.

[0027] The following description follows the operating mode in which the first impeller 5 draws air to the vicinity of the battery 39 and the second impeller 6 exhausts air to the outside. The outside air can be transported to the vicinity of the filter cylinder 4 through the first heat dissipation hole 10 and the second heat dissipation hole 12 at the top. After being filtered, it is transported to the vicinity of the battery 39 through the third heat dissipation hole 13. The high-temperature air around the battery 39 will be discharged to the outside through the third heat dissipation hole 13, the second heat dissipation hole 12 and the first heat dissipation hole 10 at the bottom. During this process, impurities in the air will be blocked on the outer surface and inside of the upper filter cylinder 4, while the lower filter cylinder 4 will be in a relatively clean state.

[0028] As the connecting ring 7 rotates, the control block 17 undergoes centrifugal motion, sliding in all directions within the control groove 18. The tension spring 19 is stretched, and the control block 17 pushes hydraulic oil to flow into the annular cavity 15, increasing the pressure within the annular cavity 15. The rubber ring 14 deforms under the inner pressure, and the middle of the rubber ring 14 protrudes outward, squeezing the middle of the filter cylinder 4. This separates the upper and lower sides of the filter cylinder 4, reducing the amount of gas flowing downward through the filter cylinder 4.

[0029] When no auxiliary heat dissipation is required, the drive motor 33 stops running, the connecting ring 7 speed decreases, the tension spring 19 pulls the control block 17 to slide back and reset, the pressure inside the annular cavity 15 decreases, the rubber ring 14 resets, reducing the pressure against the filter cylinder 4. At this time, opening the top cover 38 allows the filter cylinder 4 to be pulled out, completing the replacement operation of the filter cylinder 4. At the same time, under the pull of the elastic rope 30, the fixed frame 28 resets to the middle position of the rotating groove 29, the first heat dissipation hole 10 is disconnected from the second heat dissipation hole 12, and the entire box is then in a closed state, enhancing the protection of the battery 39.

[0030] When the drive motor 33 is started again, the rotation direction of the drive gear 34 is reversed, which changes the gas delivery direction of the first impeller 5 and the second impeller 6, drawing air from the bottom and exhausting it from the top. At this time, the filter cylinder 4 at the bottom can be used for filtration, while the gas exhausted from the top will back-blow the filter cylinder 4 at the top, blowing some of the impurities inside out to the outside. This process is repeated to achieve a preliminary self-cleaning function, improve the overall filtration efficiency of the filter cylinder 4, and extend the service life of the equipment.

[0031] In the initial stage of each start-up of the first impeller 5, the rotation speed of the fixed ring 20 is relatively slow. At this time, the tip of the drive block 22 will drive the filter cylinder 4 to rotate a small displacement, rotating the unused filter cylinders 4 around to the position facing the second heat dissipation hole 12 for subsequent filtration. When the rotation speed of the fixed ring 20 increases, the centrifugal force on the centrifugal block 24 increases, thereby pulling the connecting rope 25, causing the drive block 22 to slide in the device groove 21 and compress the first spring 23. After that, the drive block 22 releases contact with the inner wall of the filter cylinder 4, and the position of the filter cylinder 4 is fixed and limited by the middle rubber ring 14, realizing the switching of the position of the filter cylinder 4. This allows the filter cylinder 4 as a whole to continuously adjust the position of use each time it is used, rather than only a part being used continuously, thereby improving the efficiency of use and extending the service life.

[0032] It is worth noting that, in order to prevent the second impeller 6 from continuously rubbing against the friction block 31 during rotation, an electromagnet can be installed inside the fixed frame 28. When the friction block 31 is pushed to one side of the rotating groove 29 by the second impeller 6, the fixed frame 28 abuts against the side wall of the rotating groove 29. At this time, the electromagnet is activated and attracts the friction block 31 and the side wall of the rotating groove 29, releasing the contact between the friction block 31 and the second impeller 6, while also ensuring that the fixed frame 28 can be stably fixed in the required position. Only when the second impeller 6 stops running, the drive motor 33 and the electromagnet are simultaneously de-energized, releasing the attraction. Under the pull of the elastic rope 30, the rotating cylinder 9 slowly resets and closes the connection between the first heat dissipation hole 10 and the second heat dissipation hole 12.
