Abstract

The present disclosure provides an autonomous robot, configured to perform a cleaning function and an emptying function.

Claims (46)

1. An intelligent cleaning system, comprising:

an autonomous robot, configured to perform a cleaning function and an emptying function, comprising:

a first receiving part, configured to receive an object collected by the autonomous robot when performing the cleaning function;

a first air duct, pneumatically connected with the first receiving part; and

a suction device, configured to generate airflow passing through the first receiving part, and be in a closable pneumatical connection with the first receiving part via the first air duct; and

a dock station, configured to be docked by the autonomous robot to empty and collect the object from the first receiving part, the dock station comprising:

a second receiving part, configured to receive the object emptied from the first receiving part;

a second air duct, pneumatically connected with the second receiving part and configured to allow the object to enter the second receiving part along with the airflow; and

a third air duct, pneumatically connected with the second receiving part and configured to allow the airflow to flow out of the second receiving part,

wherein, in a state when the autonomous robot is docked with the dock station to perform the emptying function, the intelligent cleaning system is configured to close the first air duct, and the first receiving part is pneumatically connected with the suction device via the second air duct, the second receiving part, and the third air duct,

wherein a working power of the suction device when the autonomous robot empties the object to the dock station during the emptying function is greater than another working power of the suction device when the autonomous robot collects the object from an to-be-cleaned surface during the cleaning function,

wherein the autonomous robot is provided with an air return inlet pneumatically connected with the suction device;

wherein the autonomous robot is further provided with:

a first valve, configured to control the first air duct to open and close; and

a third valve, configured to control the air return inlet to open and close;

wherein when the first valve is in an open state, the third valve is in a closed state; and when the third valve is in an open state, the first valve is in a closed state, and

wherein the third valve, in the open state, is configured to limit movement of the first valve, causing the first valve to be locked in the closed state, and preventing the first air duct from being directly connected to the third air duct,

wherein the first valve is provided with an extension part, and the first valve and the third valve are arranged in such a manner that, when the third valve is in the open state, the third valve abuts on the extension part, thereby restricting the first valve in the closed state.

2. The intelligent cleaning system according to claim 1 , wherein the autonomous robot is provided with an emptying exit pneumatically connected with the first receiving part;

in the state when the autonomous robot is docked with the dock station, the second air duct is pneumatically connected with the first receiving part via the emptying exit, and the third air duct is pneumatically connected with the suction device via the air return inlet.

3. The intelligent cleaning system according to claim 2 , wherein the autonomous robot is further provided with: a second valve, configured to control the emptying exit to open and close; wherein when the first valve is in the open state, the second valve is in a closed state; and when the second valve is in an open state, the first valve is in the closed state.

4. The intelligent cleaning system according to claim 3 , wherein the first valve is configured to be, when the autonomous robot performs the cleaning function, switched from the closed state to the open state in response to suction action of the suction device, and switched from the open state to the closed state in response to gravity action when the suction device stops working.

5. The intelligent cleaning system according to claim 3 , wherein the dock station is provided with a protrusion, and the protrusion is configured to, when the autonomous robot is docked with the dock station, push the second valve and the third valve to switch the second valve and the third valve from the closed state to the open state.

6. The intelligent cleaning system according to claim 3 , wherein at least two of the first valve, the second valve, and the third valve are configured as an integral structure.

7. The intelligent cleaning system according to claim 1 , wherein a first filter device is provided between the first receiving part and the suction device.

8. The intelligent cleaning system according to claim 7 , wherein the autonomous robot further comprises a vibrating device and the vibrating device is attached to the first filter device and configured to drive the first filter device to vibrate when the autonomous robot performs the cleaning function.

9. The intelligent cleaning system according to claim 1 , wherein a second filter device is provided between the second receiving part and the third air duct.

10. The intelligent cleaning system according to claim 1 , wherein a one-way valve is provided in the second air duct or between the second air duct and the second receiving part, and the one-way valve is configured to be opened toward the second receiving part.

11. The intelligent cleaning system according to claim 10 , wherein the one-way valve is configured to be switched from a closed state to an open state in response to suction action of the suction device and switched from the open state to the closed state in response to gravity action when the suction device stops working.

12. An autonomous robot, wherein the autonomous robot is configured to perform a cleaning function and an emptying function, and comprises:

a first receiving part, configured to receive an object collected by the autonomous robot when performing the cleaning function, and be in a closable pneumatical connection with a dock station via an emptying exit;

a first air duct, pneumatically connected with the first receiving part; and

a suction device, configured to generate an airflow passing through the first receiving part, be in a closable pneumatical connection with the first receiving part via the first air duct, and be in a closable pneumatical connection with the dock station via an air return inlet;

wherein in a state when the autonomous robot performs the cleaning function, the first air duct is in an open state and the emptying exit and the air return inlet are in a closed state; and, in a state when the autonomous robot performs the emptying function, the first air duct is in a closed state and the emptying exit and the air return inlet are in an open state,

wherein a working power of the suction device when the autonomous robot empties the object to the dock station during the emptying function is greater than another working power of the suction device when the autonomous robot collects the object from an to-be-cleaned surface during the cleaning function,

wherein the autonomous robot is further provided with:

a first valve, configured to control the first air duct to open and close; and

a third valve, configured to control the air return inlet to open and close;

wherein when the first valve is in an open state, the third valve is in a closed state; and when the third valve is in an open state, the first valve is in a closed state, and

wherein the third valve, in the open state, is configured to limit movement of the first valve, causing the first valve to be locked in the closed state, and preventing the first air duct from being directly connected to the third air duct,

wherein the first valve is provided with an extension part, and the first valve and the third valve are arranged in such a manner that, when the third valve is in the open state, the third valve abuts on the extension part, thereby restricting the first valve in the closed state.

13. The autonomous robot according to claim 12 , further comprising:
