Abstract

This application relates to a pool robot. The pool robot includes a housing, a filtering box, and a water baffle plate. The housing is provided with a first water outlet hole and an accommodation cavity. The filtering box is disposed in the accommodation cavity. A side wall of the accommodation cavity is provided with a second water outlet hole. The water baffle plate is connected to a side of the side wall of the accommodation cavity, and the side is away from the filtering box. The water baffle plate is provided over the second water outlet hole. When the pool robot is located in water, the water baffle plate closes the second water outlet hole. When the pool robot leaves the water, the water baffle plate is opened, and water in the filtering box is drained through the second water outlet hole and the first water outlet hole.

Claims (39)

1. A pool robot, comprising:

a housing, wherein a first water outlet hole is provided on a lower end surface of the housing, and the housing is provided with an accommodation cavity;

a filtering box disposed in the accommodation cavity, wherein a second water outlet hole is provided on the accommodation cavity;

a water baffle plate, wherein the water baffle plate is disposed on the accommodation cavity and provided over the second water outlet hole, and when the pool robot is located in water, the water baffle plate closes the second water outlet hole; and

a handle, wherein the handle is provided on the housing, wherein in a process in which the pool robot is leaving the water, the handle is lifted, the first water outlet hole becomes located lower than the second water outlet hole, and the water baffle plate does not close the second water outlet hole, thereby allowing the second water outlet hole to communicate with the first water outlet hole, enabling water in the filtering box and water in the accommodation cavity to flow out through the second water outlet hole before being drained from the housing through the first water outlet hole.

2. The pool robot according to claim 1 , wherein the water baffle plate is made of a flexible waterproof material.

3. The pool robot according to claim 1 , wherein an area of the water baffle plate is greater than an area of the second water outlet hole.

4. The pool robot according to claim 1 , wherein the second water outlet hole is provided on a side wall or a bottom of the accommodation cavity.

5. The pool robot according to claim 1 , wherein at least one side of the water baffle plate is intermittently connected to the accommodation cavity.

6. The pool robot according to claim 1 , wherein the handle is disposed at a front end of the housing.

7. The pool robot according to claim 1 , wherein when the handle is lifted, the pool robot tilts.

8. The pool robot according to claim 7 , wherein when the handle is lifted, the lower end surface of the housing and a horizontal plane form an included angle of 45° to 75°.

9. The pool robot according to claim 1 , further comprising:

a filter driving assembly configured to drive the water in a pool to enter the filtering box, wherein the filtering box is closer to the handle than the filter driving assembly.

10. The pool robot according to claim 9 , further comprising:

a first water inlet provided on the lower end surface of the housing;

a third water outlet hole provided on an upper end surface of the housing; and

a first cavity provided in the housing, wherein:

the filter driving assembly comprises a main water pump, the main water pump is provided in the first cavity, and a water inlet hole is provided on a side wall of the accommodation cavity to allow the accommodation cavity to communicate with the first cavity; and

the first water inlet, the filtering box, the accommodation cavity, the water inlet hole, the main water pump, and the third water outlet hole are sequentially in fluid communication to form a cleaning water path.

11. The pool robot according to claim 10 , wherein the accommodation cavity is closer to the handle than the first cavity.

12. The pool robot according to claim 1 , further comprising a filtering box cavity, wherein the filtering box cavity is disposed in the housing, and the accommodation cavity is formed in the filtering box cavity.

13. The pool robot according to claim 10 , wherein the second water outlet hole is closer to the lower end surface of the housing than the water inlet hole.

14. The pool robot according to claim 10 , wherein in a moving direction of the pool robot, a projection of the second water outlet hole on the lower end surface of the housing is located between the first water inlet and the first water outlet hole.

15. The pool robot according to claim 10 , wherein in a forward direction of the pool robot, the handle, the filtering box, the water inlet hole, and the third water outlet hole are sequentially arranged from front to back.

16. The pool robot according to claim 10 , further comprising:

an electric control box, wherein the electric control box comprises a sealed mounting cavity and a sealed upper cover, wherein:

the main water pump comprises an impeller and a motor, and the motor is disposed in the electric control box; and

the first water inlet, the filtering box, the accommodation cavity, the water inlet hole, the impeller of the main water pump, and the third water outlet hole are sequentially in fluid communication to form the cleaning water path.

17. The pool robot according to claim 16 , wherein the first cavity comprises a first sub-cavity and a second sub-cavity, wherein:

the electric control box is disposed in the second sub-cavity; and

the impeller is disposed in the first sub-cavity, and an output shaft or a transmission shaft of the motor extends out of the sealed upper cover of the electric control box and extends into the first sub-cavity to be connected to the impeller to drive the impeller to rotate.

18. The pool robot according to claim 1 , wherein there are a plurality of first water outlet holes, and the plurality of first water outlet holes are provided in an array, and/or there are a plurality of second water outlet holes, and the plurality of second water outlet holes are provided in an array.

19. The pool robot according to claim 1 , wherein when the pool robot is located in the water, under the action of a main water pump, the water baffle plate is attached to the accommodation cavity, so that the water baffle plate closes the second water outlet hole; and in the process in which the pool robot is leaving the water, under a gravity of the water in the filtering box and a gravity of the water in the accommodation cavity, the water baffle plate is driven to move away from the second water outlet hole, so that the water baffle plate does not close the second water outlet hole.

20. A pool robot, comprising:

a housing, wherein a first water outlet hole is provided on a lower end surface of the housing, and the housing is provided with an accommodation cavity;

a filtering box disposed in the accommodation cavity, wherein a second water outlet hole is provided on the accommodation cavity; and

a water baffle plate, wherein the water baffle plate is disposed on the accommodation cavity and provided over the second water outlet hole, and when the pool robot is located in water, the water baffle plate closes the second water outlet hole; and

in a process in which the pool robot is leaving the water, the pool robot tilts, the first water outlet hole becomes located lower than the second water outlet hole, and the water baffle plate does not close the second water outlet hole, thereby allowing the second water outlet hole to communicate with the first water outlet hole, enabling water in the filtering box and water in the accommodation cavity to flow out through the second water outlet hole before being drained from the housing through the first water outlet hole.
