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 (34)

1. A water surface automatic cleaning apparatus, comprising:

a main body comprising a cavity inside; and

a garbage bin configured at the cavity and comprising an inlet on a side of the garbage bin and an anti-leakage baffle on the garbage bin, the anti-leakage baffle being configured to allow to open or close at least a part of area of the inlet by rotating,

a rotating element configured near to the inlet on the garbage bin or the main body and configured to feed garbage in water into the garbage bin during rotating, and a shaft lever of the anti-leakage baffle is positioned below all portions of the rotating element.

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

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 a drivable shaft lever to allow driving 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 advances on a water surface, to open at least a part of area of the inlet.

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

a limit part configured 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 5 , wherein the anti-leakage baffle is configured inside the garbage bin and near the inlet.

7. 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 area of the inlet is closed by the anti-leakage baffle.

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

9. 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 automatic water surface cleaning apparatus stops moving forward on a water surface, to close at least a part of area of the inlet.

10. The water surface automatic cleaning apparatus according to claim 1 , wherein when the rotating element rotates, the anti-leakage baffle is in open 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 with or opposite to the direction of 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. A water surface automatic cleaning apparatus, comprising:

a main body comprising a cavity inside; and

a garbage bin configured at the cavity and comprising an inlet on a side of the garbage bin and an anti-leakage baffle on the garbage bin, the anti-leakage baffle being configured to allow to open or close at least a part of area of the inlet by rotating,

a rotating element configured near to the inlet on the garbage bin or the main body and configured to feed garbage in water into the garbage bin during rotating, and a shaft lever of the anti-leakage baffle is positioned below the rotating element,

wherein the anti-leakage baffle is rotatably connected to the garbage bin,

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

17. A water surface automatic cleaning apparatus, comprising:

a main body comprising a cavity inside; and

a garbage bin configured at the cavity and comprising an inlet on a side of the garbage bin and an anti-leakage baffle on the garbage bin, the anti-leakage baffle being configured to allow to open or close at least a part of area of the inlet by rotating,

a rotating element configured near to the inlet on the garbage bin or the main body and configured to feed garbage in water into the garbage bin during rotating, and a shaft lever of the anti-leakage baffle is positioned below the rotating element,

wherein the anti-leakage baffle is rotatably connected to the garbage bin,

wherein a free end of the anti-leakage baffle is above a water line when at least a part of an area of the inlet is closed by the anti-leakage baffle.

18. The water surface automatic cleaning apparatus according to claim 17 , wherein an air chamber is configured on the anti-leakage baffle, or a counterweight is configured on the anti-leakage baffle, or an air chamber and a counterweight are configured on the anti-leakage baffle.
