DETAILED DESCRIPTION

The present disclosure will be described in detail with reference to the accompanying drawings of the embodiments of the present disclosure. It is apparent that the embodiments described herein are only a part of the embodiments of the present disclosure, not all embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present disclosure.

Referring to FIGS. 1-5, the present disclosure provides a technical solution. A power output structure for a swimming pool cleaning robot includes a swimming pool robot body 1, a drive mechanism is provided on two sides of the swimming pool robot body 1, a cleaning roller 5 is rotatably installed at a bottom of forward end of the swimming pool robot body 1, and a driving device 6 is provided inside the swimming pool robot body 1, and the driving device 6 is configured to simultaneously drive the drive mechanism to move forward and drive the cleaning roller 5 to rotate for cleaning. A power source for the drive mechanism and the cleaning roller 5 is come directly from the driving device 6, and a transmission ratio of the driving device 6 to the drive mechanism is greater than a transmission ratio of the driving device 6 to the cleaning roller 5.

The driving device 6 includes a first gear 62 fixedly mounted on an output shaft of a motor 61, a fourth gear 65 rotatably mounted on a shaft 11, and a third gear 64 fixedly mounted on an end near the drive mechanism of the cleaning roller 5. The first gear 62, the fourth gear 65, and the third gear 64 are sequentially meshed.

Furthermore, a rotation speed of the cleaning roller 5 is close to a rotation speed of the motor 61 through a transmission of the first gear 62, the fourth gear 65, and the third gear 64. Therefore, when the driving wheel 2 rotates one revolution, the cleaning roller 5 rotates multiple revolutions. The high-speed rotating cleaning roller 5 improves the cleaning performance of the swimming pool cleaning robot.

The drive mechanism includes a driving wheel 2 and a driven wheel 3 rotatably mounted on the swimming pool robot body 1, a same track 4 is rotationally mounted on the driving wheel 2 and the driven wheel 3.

The driving wheel 2 is rotatably mounted on a shaft 11 provided on the swimming pool robot body 1, and an internal gear portion 21 is provided on an inner side of the driving wheel 2. The driving device 6 further includes the motor 61 fixedly mounted inside the swimming pool robot body 1, a second gear 63 is fixedly mounted on the output shaft of the motor 61, and the second gear 63 is fixedly connected to the first gear 62. The second gear 63 meshes with the internal gear portion 21.

Furthermore, the motor 61 needs to drive the second gear 63 to rotate several times before driving the driving wheel 2 to rotate one revolution through the internal gear portion 21. Therefore, it can not only reduce a speed of the driving wheel 2 and make the driving wheel 2 travel slowly, but also increase a torque during the transmission of the driving wheel 2, which the driving wheel 2 accessible to more areas.

When the driving device 6 drives the driving wheel 2 to rotate one revolution, the cleaning roller 5 is simultaneously driven to rotate multiple revolutions.

Furthermore, when the driving device 6 drives the driving wheel 2 to rotate one circle, it will simultaneously drive the cleaning roller 5 to rotate multiple circles.

Both sides of the driving wheel 2 and the driven wheel 3 are equipped with annular protrusions.

In addition, the annular protrusions on both sides of the driving wheel 2 and the driven wheel 3 can limit a position of a track 4 installed on the driving wheel 2 and the driven wheel 3, thereby avoiding the track 4 from falling off the driving wheel 2 and the driven wheel 3 during rotation.

The working principle is as follows. When in use, by starting the motor 61 to rotate, the motor 61 drives the second gear 63 to rotate, causing the driving wheel 2 to rotate. The rotation of the driving wheel 2 will drive the track 4 to rotate, thus achieving the driving of the swimming pool robot main body 1. At the same time, when the motor 61 rotates, the first gear 62 will drive the fourth gear 65 to rotate, the fourth gear 65 will then drive the third gear 64 to rotate, and the third gear 64 will then drive the cleaning roller 5 to rotate and make it sweep and clean the swimming pool.

The above description is only the preferred embodiment of the present disclosure. However, the scope of protection of the present disclosure is not limited to this. Any person skilled in the art familiar with the technical field of the present disclosure, within the technical scope disclosed by the present disclosure, should be covered within the scope of protection of the disclosure by equivalent replacement or modification based on the technical solution and the present disclosure concept of the present disclosure.
