The cleaning unit 2 includes cleaning motor, cleaning shaft 23 rotatably connected to the machine body 1 and cleaning brush 22 connected to the cleaning shaft 23. The transmission structure includes motor gear 42 drivingly connected to the cleaning motor 41, drum gear 21 connected to the cleaning shaft 23 and first gear 33 formed in the inner ring of the walking wheel 31. The motor gear 42 and / or the drum gear 21 are engaged with the first gear 33. When the motor gear 42 and the drum gear 21 are both engaged with the first gear, the rotation of the motor gear 42 is driven by the cleaning motor to drive the first gear 33 to rotate, so that the track 32 rotates. The rotation of the first gear 33 drives the drum gear 21 to rotate, so that the cleaning shaft and the cleaning brush rotate. By changing the transmission mode of the pool cleaner, the cleaning unit 2 has sufficient residence time during the pool cleaning process, so that each place of the pool can be fully cleaned, and the cleaning efficiency of the pool is improved.

By arranging the balance gear 5, the meshing stability of the motor gear 42 and the first gear 33 is improved, and the motor gear 42 and the first gear 33 are prevented from being separated, and the advancing efficiency of the walking unit 3 is improved. The improvement of stability not only ensures the smooth operation of the transmission structure, but also significantly improves the advancing efficiency of the walking unit 3. At the same time, the addition of the balance gear 5 also enhances the durability and reliability of the entire transmission structure, so that the pool cleaner can maintain excellent cleaning performance in various complex environments, and bring users a more efficient and convenient pool cleaning experience.

[0031] In a specific implementation case, as shown in the figure, Figure 3 As shown in the figure, the motor gear 42 and the first gear 33 have a gap therebetween, the drum gear 21 is in meshing connection with the first gear 33, and the center position of the walking wheel 31 is provided with a first hub rotatably connected to the machine body 1. The outer ring of the first hub is formed with a second gear 6, the motor gear 42 is in meshing connection with the second gear 6. By integrally arranging the second gear 6 on the outer ring of the first hub, the second gear 6 is in meshing connection with the motor gear 42, so as to prevent the motor gear 42 and the first gear 33 from being separated, and at the same time, the power is transmitted to the first hub, the stability of the first hub during rotation is improved, and the advancing efficiency of the walking unit 3 is improved.

This not only simplifies the complexity of the transmission structure, but also enhances the overall strength and durability. This design makes the connection between the second gear 6 and the first hub more compact, reducing the problem of loosening or wear caused by long-term use or high-intensity work. At the same time, the integrally formed design also reduces the assembly error between the parts, further improving the precision and efficiency of the transmission structure. In addition, this design also helps to reduce the manufacturing cost and improve the production efficiency, making the pool cleaner more economical and easy to maintain.

[0033] Preferably, the second gear 6 can also be fixedly connected to the first hub, and the first hub can also be fixedly connected to the walking wheel. The fixed connection mode can be bolted connection, chain groove fixed connection, shaft hole fixed connection, etc.

[0036] Preferably, as shown in Figure 6 As shown, the engagement design of the third gear 7 and the drum gear 21 not only realizes effective power transmission, but also enables the cleaning drum of the pool cleaner to rotate synchronously, thereby improving the cleaning efficiency. As a key component of the pool cleaner, the stable rotation of the drum gear 21 is crucial for removing dirt on the pool bottom and the pool wall. Through the direct engagement of the third gear 7 and the drum gear 21, the intermediate link in the transmission chain is reduced, the energy loss is reduced, and sufficient power is ensured for the cleaning drum. When the third gear 7 fails due to long-term use or unexpected circumstances, maintenance personnel can quickly locate the problem, and the third gear 7 can be replaced or repaired without disassembling the entire transmission structure, thereby greatly shortening the maintenance time and improving the overall reliability and use efficiency of the equipment.
