Description

Improved structure of cordless waxing machine

The present invention relates to a cordless waxing machine, and more particularly to an improved structure of a cordless waxing machine with soft start control and enhanced heat dissipation effect.

Currently, in addition to the traditional manual operation for waxing or polishing wood or metal surfaces, some related industries have also launched some pneumatic or electric driven grinding tools. However, the existing pneumatic or electric driven grinding tools generally have problems such as complex structure, large size and bulkiness, and must be connected to an external power source with pipes or wires, which easily causes inconvenience and restrictions in carrying and operation. In addition, there are currently few pneumatic or electric driven grinding tools on the market. The grinding tool is also equipped with a speed control switch. However, once the control switch is adjusted to the desired setting, the tool will start up again at the speed set to that setting. This can easily generate a large inrush current, causing a voltage increase and further damaging the motor. Furthermore, the internal operation of the grinding tool generates heat, which cannot be effectively dissipated, potentially damaging the internal components of the grinding tool.

Therefore, how to solve the above-mentioned problems and shortcomings in usage is the direction that the inventors of this invention and related manufacturers in this industry are eager to research and improve.

Therefore, in order to effectively solve the above-mentioned problems, the main purpose of the present invention is to provide an improved structure of a cordless waxing machine with soft start control and enhanced heat dissipation effect.

The drive assembly 331 drives the pivot 342 to rotate. Furthermore, the pivot 342 is equipped with the counterweight 3421. Therefore, when the pivot 342 drives the waxing plate 343 to rotate, the counterweight 3421 enhances the eccentric rotation effect and drives the pivot 342 and waxing plate 343 to rotate rapidly, allowing the user to perform surface treatments such as grinding or waxing on workpieces.

Please refer to the aforementioned figures and Figures 4 and 5, which are schematic diagrams 1 and 2 of the airflow of the improved structure of the wireless waxing machine of the present invention. When the control switch 22 is pressed and turned on, the control circuit 25 receives the starting power, and the control circuit 25 controls the drive assembly 331 to rotate, and the drive assembly 331 drives the pivot 342 to rotate. When the drive assembly 331 rotates, the drive assembly 331 generates a rotating airflow, and the airflow generated will Air outside the top housing 2 is guided through the top through-hole 24 into the top housing 2's top accommodating space. It then passes from the top accommodating space through the top channel 261 and through the drive assembly 331, and then through the bottom channel 332 to the bottom accommodating space and out through the bottom opening 32. This allows the drive assembly 331 to continuously provide external airflow to dissipate heat throughout the entire interior during operation, effectively removing internal heat energy and thereby enhancing overall heat dissipation.
