In summary, the swimming pool cleaning robot provided by the utility model has a simple structure, the water inlet 11 occupies a small space inside the swimming pool cleaning robot, and the internal assembly space of the swimming pool cleaning robot can be used for arranging other functional devices (such as a battery and the like), so that the performance of the swimming pool cleaning robot is improved;

in addition, when the operator cleans and guarantees the swimming pool cleaning robot, the operator only needs to clean one water inlet 11, so that the time for cleaning the water inlet 11 by the operator can be shortened, and the time cost for the operator when the swimming pool cleaning robot is used is reduced;

in addition, the whole buoyancy of the swimming pool cleaning robot can be changed after the existing swimming pool cleaning robot absorbs the dirt in the water, so that the existing water inlet 11 cannot be right against the swimming pool water surface 3 or the swimming pool bottom, and the effect of absorbing and filtering the dirt of the existing swimming pool cleaning robot is affected; the swimming pool cleaning robot provided by the utility model can adjust the floating posture of the swimming pool cleaning robot in real time so as to ensure that the water inlet 11 is over against the swimming pool water surface 3 or the swimming pool bottom, thereby ensuring the absorption and filtration effects of the swimming pool cleaning robot on dirt in water.

The foregoing description is only illustrative of the present utility model and is not intended to limit the scope of the utility model, and all equivalent changes made by the specification and drawings of the present utility model, or direct or indirect application in the relevant art, are included in the scope of the present utility model.

Claims (11)

1. The swimming pool cleaning robot is characterized by comprising a main body and a floating posture adjusting module, wherein the main body can float on the water surface of a swimming pool or sink to the bottom of the swimming pool, a water inlet for absorbing water into the main body is formed in the main body, the floating posture adjusting module is arranged in the main body, and the floating posture adjusting module is used for adjusting the floating posture of the swimming pool cleaning robot in water; when the swimming pool cleaning robot floats on the water surface of the swimming pool, the water inlet is close to or right against the water surface of the swimming pool; when the swimming pool cleaning robot sinks to the bottom of the swimming pool, the water inlet is close to or right against the bottom of the swimming pool;

the floating gesture adjusting module comprises a buoyancy adjusting bin, wherein the buoyancy adjusting bin is arranged on one side in the main body, and is used for controlling the swimming pool cleaning robot to float on the water surface of the swimming pool or sink to the bottom of the swimming pool, and/or adjusting the floating gesture of the swimming pool cleaning robot in water.

2. A swimming pool cleaning robot as recited in claim 1, wherein the water inlet is provided at a bottom of the main body or at a side of the main body near the bottom.

3. A pool cleaning robot as claimed in claim 2, wherein the float attitude adjustment module adjusts the attitude of the pool cleaning robot as it floats on the pool water surface, the pool cleaning robot being inclined at an angle to the pool water surface so that the water inlet is adjacent to or facing the pool water surface.

4. The swimming pool cleaning robot of claim 1, wherein the main body is further provided with a water outlet, and a water flow channel is formed between the water inlet and the water outlet.

5. A swimming pool cleaning robot as recited in claim 4, wherein the water outlet is provided at a top of the main body and/or at a side of the main body remote from the water inlet.

6. A swimming pool cleaning robot as recited in claim 4, further comprising a water pump at least partially positioned in the water flow channel.

7. A swimming pool cleaning robot as recited in claim 4, further comprising a filter disposed in the water flow channel.

8. A swimming pool cleaning robot as recited in claim 1, further comprising a cleaning device disposed on the body proximate the water inlet.

9. The swimming pool cleaning robot of claim 1, further comprising a controller and a detection device, wherein the controller and the detection device are both disposed in the main body, and wherein the controller is connected to the detection device and the float posture adjustment module, respectively.

10. A swimming pool cleaning robot as recited in claim 9, wherein the detection device is disposed in the body proximate the water inlet.

11. A swimming pool cleaning robot as recited in claim 9, wherein the detection means comprises a capacitive liquid level sensor.
