Abstract
The present disclosure relates to a cleaner having a cleaning module and relates to a cleaner which includes a rolling prevention assembly that has one side disposed on a pitching member and the other side disposed on a rolling member, blocks rotation of the rolling member when an angle formed by a ground and a rolling axis is more than a reference value, and allows the rotation of the rolling member when the angle is less than the reference value, thereby blocking the rotation of the rolling member when the angle formed by the ground and the rolling axis is more than the reference value so that the cleaner can turn and allowing the rotation of the rolling member when the angle is less than the reference value so that a low gap can be cleaned.
Claims15
A cleaner comprising:
- a cleaning module configured to suction external air;
- and a main body configured to provide a suction force to the cleaning module,
- wherein the cleaning module includes:
- a suction member that forms an appearance, forms a space therein, and suctions the air;
- a pitching member that is disposed between the suction member and the main body, has a pitching axis disposed in a left-right direction, and rotates the main body about the pitching axis;
- a rolling member that is disposed between the pitching member and the main body, has a rolling axis passing through the suction member and the main body, and rotates the main body about the rolling axis;
- and
- a rolling prevention assembly that has one side disposed on the pitching member and the other side disposed on the rolling member, blocks rotation of the rolling member when an angle formed by a ground and the rolling axis is more than a reference value, and allows the rotation of the rolling member when the angle is less than the reference value.
A cleaner comprising:
- a cleaning module configured to suction external air;
- and a main body configured to provide suction power to the cleaning module,
- wherein the cleaning module includes:
- a suction member configured to suction the air;
- a pitching member that has a front end rotatably coupled to the suction member, has a pitching axis disposed on the front end in a left-right direction, and rotates the main body about the pitching axis;
- a yawing member that has a front end rotatably coupled to a rear end of the pitching member, has a yawing axis disposed on the front end in a vertical direction, and rotates the main body about the yawing axis;
- a rolling member that has a front end rotatably coupled to a rear end of the yawing member, has a rolling axis passing through the yawing member and the main body, and rotates the main body about the rolling axis;
- and
- a rolling prevention assembly that has one side disposed on the yawing member and the other side disposed on the rolling member, blocks rotation of the rolling member when an angle formed by a ground and the rolling axis is more than a reference value, and allows the rotation of the rolling member when the angle is less than the reference value.
A cleaner comprising:
- a cleaning module configured to suction external air;
- and a main body configured to provide a suction force to the cleaning module,
- wherein the cleaning module includes:
- a suction member configured to suction the air;
- a fixed member having one end coupled to the suction member;
- a rotating member that has one end coupled to the other end of the fixed member and the other end connected to the main body, has a rotational axis passing through the fixed member and the main body, and rotates the main body about the rotational axis;
- and
- a rotation prevention assembly that has one side disposed on the fixed member and the other side disposed on the rotating member, blocks rotation of the rotating member when an angle formed by a ground and the rotational axis is more than a reference value, and allows the rotation of the rotating member when the angle is less than the reference value.
