An intelligent multi-directional swimming pool cleaning robot as shown in FIGS. 1-11 includes a rectangular mounting platform 1, a driving wheel 10 disposed at the bottom of the mounting platform, a control device and a plurality of brush mechanisms. All of the brush mechanisms include a first brush mechanism 2 disposed at the bottom of the mounting platform 1, a second brush mechanism 3 and a third brush mechanism 4 both disposed vertically. The second brush mechanism 3 and the third brush mechanism 4 are respectively disposed just above the two ends of the top of the mounting platform 1. The top of the mounting platform 1 is provided with a double-head driving device 5 which drives reciprocating movement of the second brush mechanism 3 and the third brush mechanism 4. Four guide columns 13 are respectively vertically disposed at four corners of the top of the mounting platform 1. The second brush mechanism 3 and the third brush mechanism 4 are slidably engaged with the guide columns 13 respectively by a horizontal sliding rod. All horizontal sliding rods respectively limit the second brush mechanism 3 and the third brush mechanism 4 to maintain the vertical state while reciprocating. The double-head driving device 5 and all the driving wheels 10 are all electrically connected to the control device. The driving wheels 10 are conventional and are not discussed for details.

Working principle: when the swimming pool cleaning machine is started, the controller controls and drive the speed reducer, and drives the rotation of the driving wheels 10. The swimming pool cleaning machine moves forward. The first roller 2b rotates against the ground, and drives the first brush roller 2a to rotate to scrub the bottom of the pool. The second roller 3b rotates against the side wall of the swimming pool and drives the second brush roller 3a to rotate to clean the side wall. The controller controls the rotation of the double-head driving motor 5a to drive the second brush mechanism 3 and the third brush mechanism 4 to reciprocate on the vertical plane to clean the side wall. When the pool cleaning machine reaches the side wall, the sensor 9 sends an electrical signal to the controller. The controller controls the driving wheels 10 to rotate in the vertical direction to drive the pool cleaning machine to turn. The above actions are repeated.

The first brush mechanism 2 includes a first support frame 2e having a U-shaped shape and a downward opening, and a horizontally disposed first brush roller 2a. The first support frame 2e is provided with a first rolling element at both ends thereof. The two ends of the first brush roller 2a are provided with a first gear 2c that cooperates with the first rolling assembly. The first rolling element includes a first roller 2b, and a second gear 2d fixedly connected to the center of the first roller 2b. The axis of the first roller 2b is parallel to the axis of the first brush roller 2a. The plane of the second gear 2d is perpendicular to the axis of the first roller 2b. The first gear 2c meshes with the second gear 2d. Both two ends of the first support frame 2e are provided with a first slot 2e1 configured to mesh with the first roller 2b. When the first roller 2b is rolled forward against the ground, the first gear 2c and the second gear 2d are rotated, thereby driving the first brush roller 2a to rotate to clean the bottom of the pool.

Referring to FIGS. 1, 3, 5, 6, 7, 8, 10 and 11, the second brush mechanism 3 includes a vertically disposed second support frame 3e having a U-shaped shape, and a vertically disposed second brush roller 3a. The second support frame 3e is provided with a second rolling element at both ends thereof. The two ends of the second brush roller 3a are provided with a third gear 3c that cooperates with the second rolling assembly. The second rolling element includes a second roller 3b, a fourth gear 3d fixedly connected to the center of the second roller 3b. The axis of the second roller 3b is parallel to the axis of the second brush roller 3a. The plane of the fourth gear 3d is perpendicular to the axis of the second roller 3b. The third gear 3c meshes with the fourth gear 3d. Both two ends of the second support frame 3e are provided with a second slot 3e1 configured to mesh with the second roller 3b. When the second roller 3b is rolled forward against the ground, the third gear 3c and the fourth gear 3d are rotated, thereby driving the second brush roller 3a to rotate to clean the side wall of the pool.

A middle portion of the second support frame 3e is provided with a first buffer assembly 6. The middle portion of the second support frame 3e is provided with a notch for mounting the first buffer assembly 6. The first buffer assembly 6 includes a first guide column 6b and a first buffer spring 6a. The first guide column 6b is vertically disposed and the first buffer spring 6a is sleeved on the first guide column 6b. When the bottom end of the second brush roller 3a abuts against the bottom of the pool, the first buffer assembly 6 prevents the second brush roller 3a from coming into contact with the bottom of the pool, causing the first roller 2b at the bottom end of the second brush roller 3a to wear.

Referring to FIGS. 1, 3, 4, 5, and 9, the third brush mechanism 4 includes a vertically disposed third support frame 4e having a U-shaped shape, and a vertically disposed third brush roller 4a.

The axis of the third roller 4b is parallel to the axis of the third brush roller 4a. The plane of the sixth gear 4d is perpendicular to the axis of the third roller 4b. The fifth gear 4c meshes with the sixth gear 4d. Both two ends of the third support frame 4e are provided with a third slot 4e1 configured to mesh with the third roller 4b. When the third roller 4b is rolled forward against the side wall of the pool, the fifth gear 4c and the sixth gear 4d are rotated, thereby driving the third brush roller 4a to rotate to clean the side wall of the pool.

A middle portion of the third support frame 4e is provided with a second buffer assembly 7. The middle portion of the third support frame 4e is provided with a notch for mounting the second buffer assembly 7. The second buffer assembly 7 includes a second guide column 7b and a second buffer spring 7a. The second guide column 7b is vertically disposed and the second buffer spring 7a is sleeved on the second guide column 7b. When the bottom end of the third brush roller 4a abuts against the bottom of the pool, the second buffer assembly 7 prevents the third brush roller 4a from coming into contact with the bottom of the pool, causing the first roller 2b at the bottom end of the third brush roller 4a to wear.

Referring to FIGS. 1, 2, 3, 4, and 11, the horizontal sliding rod includes a first sliding rod 11 and a second sliding rod 12. Two ends of the first sliding rod 11 are respectively slidably engaged with the two guide columns 13.

One end of the first connecting rod 5b away from the double-head driving motor 5a is connected to the first buffer assembly 6 through a horizontally disposed first connecting column head 6c. The first connecting column head 6c is hinged with one end of the first connecting rod 5b. The first connecting column head 6c is provided with a through hole for the first guide column 6b to pass through. The top end of the first buffer spring 6a abuts to the bottom of the first connecting column head 6c. One end of the second connecting rod 5c away from the double-head driving motor 5a is connected to the second buffer assembly 7 through a horizontally disposed second connecting column head 7c. The second connecting column head 7c is hinged with one end of the second connecting rod 5c.
