[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. By setting up a lubrication mechanism, the lubricating oil inside the speed-increasing gearbox can be sucked into the top of the second partition through the return pipe and the guide pipe. When one end of the first piston block is removed from the top of the auxiliary shell, the lubricating oil sucked into the bottom of the second partition can enter the first partition. The lubricating oil can flow back to the speed-increasing gearbox through the one-way valve. Through the circulation of the lubricating oil, it can be ensured that all key components inside the speed-increasing gearbox can be evenly lubricated, which helps to reduce the friction and wear between the components, thereby improving the operating efficiency and life of the entire device. During operation, heat will be generated inside the speed-increasing gearbox. Through the circulation of the lubricating oil, the heat can be effectively taken away, which plays a role in heat dissipation and cooling, which helps to prevent the speed-increasing gearbox from overheating, thereby protecting its internal components from damage. The circulating lubricating oil can also play a cleaning role, taking away the tiny particles and impurities inside the speed-increasing gearbox to prevent them from causing wear or blockage to the components, thereby improving the service life of the device;

[0016] 2. By setting a shielding protective member, when the device is not needed to charge the battery, the user can start the drive motor, and the output end of the drive motor drives the baffle to rotate toward the impeller, thereby shielding the front of the impeller, so as to avoid the device from running when the battery is fully charged, thereby reducing the wear of the internal parts of the device and prolonging the overall service life of the device;

[0017] 3. By setting a centrifugal slag discharger, the centrifugal force generated by the filter sleeve can throw the impurities adhering to the filter screen of the filter sleeve to the edge of the filter sleeve, and enter between two adjacent arc-shaped blocking blocks for retention. When the impurities slide between an arc-shaped blocking block and an inclined blocking block, the filter sleeve can be blocked by the inclined blocking block when it reverses, so as to prevent the impurities from gathering on the inner filter screen of the filter sleeve again, thereby ensuring the smoothness of subsequent filtering by the filter sleeve. The rapid rotation of the filter sleeve not only helps to remove impurities on the filter screen, but also improves the filtering efficiency, ensuring that the impurities in the lubricating oil are removed more effectively, and the filter screen remains clean and unobstructed, which helps to improve the filtering accuracy and reduce the pollutant content in the lubricating oil, thereby extending the service life of the speed increase gearbox and other components;

[0018] 4. By setting up a slag pushing component, when the impurities are thrown to the inner side of the arc-shaped blocking block by centrifugal force, they fall into the inner side of the slag discharge groove for accumulation. When the U-shaped rod moves laterally, it drives the connecting rod to move synchronously. When the inclined surface on one side of the trapezoidal block contacts the spherical rod, the spherical rod is pushed through the circular ring to drive the slag discharge block to move toward the groove direction, thereby pushing the impurities accumulated on the inner side of the slag discharge groove into the slag discharge shell. When the slag discharge groove enters the slag discharge shell, the slag discharge groove and the bottom of the filter sleeve are separated, so that the impurities inside the slag discharge groove can fall into the slag discharge shell and automatically fall to the outside. The automatic slag discharge mechanism ensures the continuous operation of the filtration system. Even if impurities are generated during the filtration process, they can be cleaned in time without affecting the normal operation of the system. BRIEF DESCRIPTION OF THE DRAWINGS
