Abstract

A swimming pool robot is disclosed, the swimming pool robot comprising: a first water inlet located at a bottom of the swimming pool robot, and is used for liquid to flow into the swimming pool robot; the swimming pool robot is configured to be switched from the bottom of the swimming pool to a liquid surface, wherein the first water inlet faces the bottom of the swimming pool when the swimming pool robot is on the bottom of the swimming pool or when the swimming pool robot is at the liquid surface; and when the swimming pool robot is switched from the bottom of the swimming pool to a liquid surface, the swimming pool robot has a state where the swimming pool robot is moving on a sidewall of the swimming pool.

Claims (33)

1 . A swimming pool robot, comprising:

a body provided with a buoyancy cavity, a pump and an air inlet, wherein the pump is configured to control gas to flow into the buoyancy cavity through the air inlet;

a processor disposed in the body; and

a sensor disposed in the body;

wherein when the swimming pool robot is to be switched from being underwater to floating on a water surface, the processor is configured to obtain from the sensor a detection result of whether the air inlet is located in air, and in response to the detection result indicating that the air inlet is located in air, the processor is configured to control the pump to increase a volume of the gas in the buoyancy cavity.

2 . The swimming pool robot according to claim 1 ,

wherein the sensor is configured to detect a position of the swimming pool robot, and

wherein when the swimming pool robot is to be switched from being underwater to floating on the water surface, the processor is configured to obtain from the sensor the position of the swimming pool robot, and in response to the position of the swimming pool robot meeting a preset condition, the processor is configured to determine that the air inlet is above the water surface and controls the pump to increase the volume of the gas in the buoyancy cavity.

3 . The swimming pool robot according to claim 1 , wherein when the swimming pool robot is to be switched from being underwater to floating on the water surface, the swimming pool robot has a state where a bottom surface or a top surface of the swimming pool robot is inclined with respect to the water surface.

4 . The swimming pool robot according to claim 1 , wherein the air inlet is disposed at a handle of the swimming pool robot.

5 . The swimming pool robot according to claim 1 ,

wherein the swimming pool robot is provided with multiple buoyancy cavities, and

wherein at least one of the buoyancy cavities is respectively provided on a front portion of the swimming pool robot.

6 . The swimming pool robot according to claim 5 , wherein two of the multiple buoyancy cavities are provided symmetrically at one end portion of the swimming pool robot.

7 . The swimming pool robot according to claim 1 , further comprising two propellers disposed in the swimming pool robot, wherein the two propellers are configured to propel water with different flow rates to enable the swimming pool robot to be turned around.

8 . The swimming pool robot according to claim 1 , further comprising a power water outlet portion rotatably disposed in the body and configured to change a flow direction of water.

9 . The swimming pool robot according to claim 8 , further comprising a motor and a transmission structure disposed in the swimming pool robot, wherein the transmission structure is in coordination with the motor to drive the power water outlet portion to rotate.

10 . The swimming pool robot according to claim 8 , further comprising a propeller, wherein:

the propeller and the power water outlet portion are in communication with each other through a channel, and

an orientation of the channel is adjusted to allow water to be discharged from the power water outlet portion in a first direction or in a second direction, wherein the second direction is different from the first direction.

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

a sensor disposed in the body, wherein the sensor is configured to detect whether a filtering box is in position; and

an alarm part in communication with the processor and configured to prompt a user when the filtering box is not mounted in position.

12 . The swimming pool robot according to claim 1 , further comprising a first propeller and a second propeller, wherein:

the swimming pool robot is further provided with a first power water inlet portion, a second power water inlet portion, a first power water outlet portion, and a second power water outlet portion,

the first propeller is in communication with the first power water inlet portion and the first power water outlet portion, and

the second propeller is in communication with the second power water inlet portion and the second power water outlet portion.

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

a dust box provided with a water surface dust box opening, wherein the dust box is configured to clean pool water that enters the dust box.

14 . The swimming pool robot according to claim 13 , wherein the dust box comprises a dust box roller provided in the water surface dust box opening and is configured to roll trash or impurities from the pool surface into the dust box when a surface cleaning is performed.

15 . The swimming pool robot according to claim 13 , further comprising: a trash guide member located on an outside of the water surface dust box opening and hollow inside and configured to guide trash in a water surface of the pool into the water surface dust box opening, wherein the water surface dust box opening is exposed to the pool water surface when the swimming pool robot performs water surface cleaning.

16 . The swimming pool robot according to claim 15 , the trash guide member comprising a first end that is away from the water surface dust box opening and the dust box, wherein a size of the first end is larger than a size of the water surface dust box opening.

17 . The swimming pool robot according to claim 16 , the trash guide member further comprising a second end that is connected to the water surface dust box opening and close to the dust box, a size of the second end is not smaller than the size of the water surface dust box opening.
