As shown in
Exemplarily, the first cleaning member 440 is a ground cleaning rolling brush, namely, the first cleaning member 440 is a rolling brush for cleaning ground; and the second cleaning member 560 is a water surface cleaning rolling brush, namely, the second cleaning member 560 is a rolling brush for cleaning water surface.
According to the transmission device according to the example, the driving member 200, the first driven member 400, and the second driven member 500 are configured, so that only one driving member 200 is required to drive the wheel assembly 300, the first cleaning member 440, and the second cleaning member 560, with a simple driving structure and a low manufacturing cost. The driving member 200 drives the wheel assembly 300 to rotate, so that the wheel assembly 300 moves forwards or backwards. The wheel assembly 300 can drive the first driven member 400 and the second driven member 500 to rotate during rotation, and the first driven member 400 and the second driven member 500 drive the first cleaning member 440 and the second cleaning member 560 to rotate, respectively. Therefore, different cleaning members can work, and cleaning functions of the pool cleaning robot can be diversified. Exemplarily, when the first cleaning member 440 is the ground cleaning rolling brush and the second cleaning member 560 is the water surface cleaning rolling brush, the transmission device can drive the ground cleaning rolling brush and the water surface cleaning rolling brush to rotate by driving the wheel assembly 300 to rotate. Therefore, the cleaning functions of the pool cleaning robot can be diversified.
In the example, the wheel assembly 300 includes a first wheel 310, a second wheel 320, and a conveyor belt 330, where the first wheel 310 is in transmission connection with the second wheel 320 through the conveyor belt 330, and the output end of the driving member 200 is in driving connection with the first wheel 310. Specifically, in the example, two first wheels 310 and two second wheels 320 are provided, the two first wheels 310 are configured on a front end of the body 100, and the two second wheels 320 are configured on a rear end of the body 100.
Exemplarily, the driving member 200 includes an electric motor, and the transmission device further includes a first gear 210. An output end of the electric motor is connected with the first gear 210, and the first gear 210 is engaged with the first wheel 310, so that the first gear 210 can drive the first wheel 310 to rotate. In addition, the driving member 200 may also be configured as other components capable of providing kinetic energy, which will not be limited in the example.
As shown in
Specifically, during working, after the driving member 200 is activated, the driving member 200 drives the first gear 210 to rotate. Since the first gear 210 is engaged with the first wheel 310, the first gear 210 can drive the first wheel 310 to rotate. Under the connection through the conveyor belt 330, the first wheel 310 can drive the second wheel 320 to rotate through the conveyor belt 330, the second wheel 320 drives the second gear 510 to rotate, and the second gear 510 drives the first rotary disc to rotate. Therefore, the first rotary disc drives the second rotary disc to rotate through the conveyor belt 530, the second rotary disc drives the third gear 520 to rotate, the third gear 520 drives the fifth gear 550 to rotate, and the fifth gear 550 drives the fourth gear 540 to rotate. Finally the fourth gear 540 can drive the second cleaning member 560 to rotate. When the second cleaning member 560 is the water surface cleaning rolling brush, the pool cleaning robot can clear and store garbage on a water surface.
In some alternative embodiments, the second cleaning member 560 is connected with the fourth gear 540 through a first connection shaft. In the example, the second driven member 500 is only configured on one side of the body 100, thereby simplifying the structure of the pool cleaning robot, saving on a cost, and reducing a weight.
Further, in the example, the second gear 510 is configured coaxial with the first rotary disc, the third gear 520 is configured coaxial with the second rotary disc, and the second rotary disc is configured right above the first rotary disc.

As shown in
Specifically, during working, after the driving member 200 is activated, the driving member 200 drives the first gear 210 to rotate. Since the first gear 210 is engaged with the first wheel 310, the first gear 210 can drive the first wheel 310 to rotate. Under the connection through the conveyor belt 330, the first wheel 310 can drive the second wheel 320 to rotate through the conveyor belt 330, the second wheel 320 drives the sixth gear 410 to rotate, the sixth gear 410 drives the eighth gear 430 to rotate, and the eighth gear 430 drives the seventh gear 420 to rotate. Therefore, the seventh gear 420 can drive the first cleaning member 440 to rotate. When the first cleaning member 440 is the ground cleaning rolling brush, the pool cleaning robot can clean a surface of a pool. The surface of the pool may be a bottom surface or a wall surface of the pool.

The first wheel 310 may be a front wheel of the pool cleaning robot, and the second wheel 320 may be a rear wheel of the pool cleaning robot. Exemplarily, when the pool cleaning robot is required to turn, one driving member 200 stops or decelerates working of one first wheel 310, and the other driving member 200 accelerates to drive the other first wheel 310 to rotate. Therefore, the pool cleaning robot realizes the turning action. In the example, the two driving members 200 drive the two first wheels 310 to rotate, respectively.
