[0026] This embodiment provides a rotary cleansing brush, as shown in Figure 1 and Figure 2As shown in the figure, it includes a main body 1 and a brush head 2 that can be connected to the top of the main body 1. A rotatable first output member 11 and a second output member 12 are provided at the top of the main body 1. A first brush holder 21 that can be drivingly connected to the first output member 11 and a second brush holder 22 that can be drivingly connected to the second output member 12 are provided on the brush head 2. A driving device 3 is provided in the main body 1. The driving device 3 uses a general motor. A transmission structure 4 is connected between the first output member 11 and the second output member 12 and the driving device 3 to drive the two to rotate around their own axes, as Figure 2 Figure 4 shown, the transmission structure 4 is a single gear or a gear set composed of multiple gears. When the brush head 2 is connected to the main body 1, the connecting post at the top of the first output member 11 is inserted into the slot of the first brush holder 21. A ratchet tooth is provided at the bottom of the second output member 12, and a card slot that can fit into the ratchet tooth is provided at the bottom of the second brush holder 22. When the driving device 3 works, the driving device 3 drives the first output member 11 and the second output member 12 to rotate through the transmission structure 4. Upward bristles are provided on both brush holders. The combination of several bristles can rotate alternately, so that the facial skin is subjected to pulling forces in different directions, improving the cleaning intensity while taking into account comfort. The main body 1 includes a housing 13. The driving device 3 is arranged on the housing 13. A support seat 14 is provided on the upper part of the housing 13. An accommodation cavity 100 is formed between the support seat 14 and the housing 13. The transmission structure 4 is arranged in the accommodation cavity 100. A waterproof structure 5 is arranged between the housing 13 and the support seat 14. Through the waterproof structure, the liquid flowing from the brush head 2 to the main body 1 cannot enter the accommodation cavity 100, preventing the liquid from entering the accommodation cavity 100 and affecting the normal operation of the transmission structure 4, and preventing the liquid from entering and causing the driving device 3 and the internal electronic components to leak and be damaged, thereby improving the working stability and service life of the product.

[0027] Preferably, as Figure 2As shown in the figure, a sealing member mounting groove 131 surrounding the accommodation cavity 100 is provided on the casing 13. A sealing ring plate 141 surrounding the accommodation cavity 100 and capable of being inserted into the sealing member mounting groove 131 is provided on the support seat 14. The waterproof structure 5 includes a sealing ring 51. The sealing ring 51 is matched with the shape of the sealing member mounting groove 131 and is arranged between the bottom of the sealing member mounting groove 131 and the lower end of the sealing ring plate 141. The sealing ring 51 can be made of a soft material such as silica gel or rubber as an integral structure. As a further optimization, a downward concave sealing slot 511 is provided on the upper surface of the sealing ring 51. A plugging ring 142 capable of being inserted into the sealing slot 511 is provided at the lower end of the sealing ring plate 141, so that the sealing ring plate 141 is tightly connected to the sealing ring 51. And when the plugging ring 142 is inserted into the sealing slot 511, the structures on both sides of the sealing ring 51 can be squeezed towards the two side walls of the sealing member mounting groove 131, thereby improving the fastening property and the waterproof sealing performance.

[0028] As a preferred embodiment, as Figure 2 shown, a sealing cover plate 132 is provided inside the casing 13. The sealing cover plate 132 divides the accommodation cavity 100 into an electric control cavity 101 located below and a transmission cavity 102 located above. The driving device 3 is arranged in the electric control cavity 101, and the transmission structure 4 is arranged in the transmission cavity 102. Preferably, the shape of the sealing cover plate 132 is made to match the shape of the top of the driving device 3, so that the driving device 3 and the electronic components can be arranged in the electric control cavity 101, further improving the waterproof performance.

[0029] Preferably, as Figure 3 and Figure 4 shown, the transmission structure 4 includes a first gear member 41 connected to the output shaft of the driving device 3, a second gear member 42 meshed with the first gear member 41.
