Abstract

The present disclosure discloses a water surface automatic cleaning device, including a main body, a cavity is provided in the main body; and a garbage bin is disposed at the cavity, an inlet is disposed on a sidewall of the garbage bin, and an anti-leakage baffle is configurated to open or close at least a part of area of the inlet.

Claims (37)

1 . A water surface automatic cleaning apparatus, comprising:

a main body comprising a cavity inside;

a garbage bin arranged in the cavity and comprising an inlet on a side of the garbage bin;

an anti-leakage baffle arranged on the main body, and the anti-leakage baffle being configured to allow to open or close at least a part of an area of the inlet by rotating; and

a rotating element arranged near to the inlet on the main body and configured to feed garbage in water into the garbage bin by rotating, wherein in a direction parallel to a forward direction of the water surface automatic cleaning apparatus, a shaft lever for the anti-leakage baffle does not directly face the rotating element.

2 . The water surface automatic cleaning apparatus according to claim 1 , wherein the anti-leakage baffle is rotatably connected to the main body.

3 . The water surface automatic cleaning apparatus according to claim 2 , wherein a side of the anti-leakage baffle is hinged to the inlet through the shaft lever to drive the anti-leakage baffle to rotate around an axis of the shaft lever.

4 . The water surface automatic cleaning apparatus according to claim 3 , wherein the anti-leakage baffle is configured to rotate by a push of water flow when the water surface automatic cleaning apparatus moves forward on a water surface, to open at least a part of the area of the inlet.

5 . The water surface automatic cleaning apparatus according to claim 2 , further comprising:

a limit part arranged on the main body or the garbage bin, and configured to limit a rotation range of the anti-leakage baffle.

6 . The water surface automatic cleaning apparatus according to claim 2 , wherein a free end of the anti-leakage baffle is above a water line when at least a part of the area of the inlet is closed by the anti-leakage baffle.

7 . The water surface automatic cleaning apparatus according to claim 2 , wherein an air chamber is arranged on the anti-leakage baffle, or a counterweight is arranged on the anti-leakage baffle, or an air chamber and a counterweight are arranged on the anti-leakage baffle.

8 . The water surface automatic cleaning apparatus according to claim 1 , wherein the anti-leakage baffle is configured to reset by a buoyancy in water when the water surface automatic cleaning apparatus stops moving forward on a water surface, to close at least a part of the area of the inlet.

9 . The water surface automatic cleaning apparatus according to claim 1 , wherein when the rotating element rotates for collecting floating objects, the anti-leakage baffle is in an open state.

10 . The water surface automatic cleaning apparatus according to claim 9 , wherein when the water surface automatic cleaning apparatus stops collecting floating objects, the anti-leakage baffle is in a closed state.

11 . The water surface automatic cleaning apparatus according to claim 1 , wherein at least a part of the rotating element is above the anti-leakage baffle.

12 . The water surface automatic cleaning apparatus according to claim 1 , wherein the anti-leakage baffle and the rotating element are configured such that during a rotation of the anti-leakage baffle, a free end of the anti-leakage baffle does not contact brush blades of the rotating element even when the free end of the anti-leakage baffle is closest to the brush blades of the rotating element.

13 . The water surface automatic cleaning apparatus according to claim 1 , further comprising:

at least one power component configured to drive the anti-leakage baffle to rotate, or at least one power component configured to drive the rotating element to rotate, or at least one power component configured to drive the anti-leakage baffle and the rotating element to rotate.

14 . The water surface automatic cleaning apparatus according to claim 13 , wherein the at least one power component comprises:

a transmission component configured to drive the anti-leakage baffle to rotate in a direction covering the inlet, and to drive the rotating element to rotate in a direction same as or opposite to the direction of a rotation of the anti-leakage baffle.

15 . The water surface automatic cleaning apparatus according to claim 13 , wherein the at least one power component comprises a first power component for driving the anti-leakage baffle and a second power component for driving the rotating element.

16 . The water surface automatic cleaning apparatus according to claim 1 , wherein the garbage bin comprises a body and a flap, and the flap rotates to open or close an opening located at a bottom of the body.

17 . A water surface automatic cleaning apparatus, comprising:

a main body comprising a cavity inside;

a garbage bin arranged in the cavity and comprising an inlet on a side of the garbage bin; wherein the garbage bin is able to be taken out from the cavity;

an anti-leakage baffle arranged on the main body, and the anti-leakage baffle being configured to allow to open or close at least a part of an area of the inlet by rotating;

a rotating element arranged near to the inlet on the main body and configured to feed garbage in water into the garbage bin by rotating, wherein in a direction parallel to a forward direction of the water surface automatic cleaning apparatus, a shaft lever for the anti-leakage baffle does not directly face the rotating element; and

a solar panel arranged on a top of the main body.

18 . The water surface automatic cleaning apparatus according to claim 1 , wherein a shaft of the rotating element is parallel to the shaft lever for the anti-leakage baffle.

19 . The water surface automatic cleaning apparatus according to claim 17 , wherein a shaft of the rotating element is parallel to the shaft lever for the anti-leakage baffle.

20 . A water surface automatic cleaning apparatus, comprising:

a main body comprising a cavity inside;

a garbage bin arranged in the cavity and comprising an inlet on a side of the garbage bin;

an anti-leakage baffle arranged on the main body, and the anti-leakage baffle being configured to allow to open or close at least a part of an area of the inlet by rotating; and

a rotating element arranged near to the inlet on the main body and configured to feed garbage in water into the garbage bin by rotating, wherein in a case where the anti-leakage baffle closes the at least a part of an area of the inlet, in a forward direction of the water surface automatic cleaning apparatus, a free end of the anti-leakage baffle is not covered.

21 . The water surface automatic cleaning apparatus according to claim 20 , wherein the shaft lever for the anti-leakage baffle comprises a part which connects to a side of the anti-leakage baffle.
