Further, the number of gear teeth of the first synchronous pulley is Z 3, the number of gear teeth of the second synchronous pulley is Z 4, and the relation is satisfied: z 4/Z3 = k,0 < k < 1. Wherein k is the transmission ratio of the combination of the first synchronous pulley and the second synchronous pulley.
Illustratively, the number of teeth of the first pulley is selected to be Z 3 to be 28 and the number of teeth of the second pulley is selected to be Z 4 to be 14, such that the transmission ratio k=14/28=0.5 of the first and second pulley combination.

It can be appreciated that by controlling the transmission ratio k of the combination of the first synchronous pulley and the second synchronous pulley to be in the range of 0 to 1, the torque of the rolling brush assembly 160 can be reduced to increase the rotational speed of the rolling brush assembly 160, so that the swimming pool cleaning robot 100 has a better cleaning effect.

It will be appreciated that by providing the tracks 140 and the driven wheels 150, the internal teeth 142 of the tracks 140 can engage with the gear teeth of the drive wheel 120 and the gear teeth of the driven wheels 150, thereby facilitating the transfer of motion and power from the drive wheel 120 to the driven wheels 150, and thus through the drive wheel 120 and the driven wheels 150, the roller brush assembly 160 is moved, while through the movement of the tracks 140, the pool cleaning robot 100 is moved.
In a particular embodiment, the gear teeth of the drive wheel 120 include a plurality of first gear teeth that mesh with the gear teeth of the drive gear 110 and a plurality of second gear teeth that mesh with the inner teeth 142 of the track 140. Thus, when the driving gear 110 rotates, the driving wheel 120 is driven to rotate by the first gear teeth meshed with the driving gear 110, and the driving wheel 120 drives the crawler belt 140 to move by the second gear teeth, so that the driving force of the driving gear 110 is transmitted to the crawler belt 140, and the swimming pool cleaning robot 100 can conveniently move in a swimming pool and perform cleaning operation.

It can be appreciated that by arranging the plurality of limiting teeth 143 on the inner circumferential surface of the belt loop 141, the limiting teeth 143 can abut against the ends of the driving wheel 120 and the driven wheel 150, thereby playing a limiting role, limiting the movement of the driving wheel 120 and the driven wheel 150 in the direction away from the rolling brush assembly 160, increasing the stability of the transmission, and thus prolonging the service life of the swimming pool cleaning robot 100.
As shown in fig. 6, illustratively, each of the internal teeth 142 is provided with one of the limiting teeth 143 at a position, so that the number of the internal teeth 142 is the same as that of the limiting teeth 143, the limiting effect is better, and the transmission stability is higher.

It can be appreciated that, through the setting of the limiting cover plate 170, the limiting cover plate 170 can be abutted with the limiting teeth 143 to limit the track 140 to move along the direction away from the rolling brush assembly 160, thereby increasing the stability of the transmission process, and the limiting cover plate 170 also plays a role in shielding, thereby playing a role in protecting the driving wheel 120, the driven wheel 150 and the transmission assembly 130, and further prolonging the service life of the swimming pool cleaning robot 100.
As shown in fig. 3, in one embodiment, the width of the belt 133 is W, satisfying the relationship: w is more than or equal to 10mm and less than or equal to 26mm.

It should be noted that, if the width W of the belt 133 is too large, the belt 133 tends to be wasted in size, which increases the cost. If the transmission belt 133 is too small, it may result in poor power transmission stability, and insufficient load capacity, and a low service life.
It will be appreciated that by controlling the width W of the belt 133 to be in the range of 10mm to 26mm, it is possible to ensure that the belt-driven process has sufficient stability to meet the power requirements of the roller brush assembly 160, while reducing the waste of the size of the belt 133 and reducing the development cost of the pool cleaning robot 100.
