Abstract
A vacuum cleaner includes a main body and a suction nozzle. The suction nozzle includes a housing, a driver, a rotating brush, and a detachable cover. A pressing button is mounted in the housing. The detachable cover is rotated about the rotational axis of the rotating brush to be mounted in the housing. The pressing button selectively blocks rotation of the detachable cover.
Claims15
A vacuum cleaner comprising:
- a suction nozzle configured to suction dust from a floor;
- and
- a main body configured to receive the dust,
- wherein the suction nozzle comprises:
- a housing that defines an inlet configured to provide the dust to the main body,
- a rotating brush disposed at the housing and configured to rotate about a rotational axis,
- a driver disposed at the housing and configured to rotate the rotating brush, the driver comprising a first shaft member configured to transfer rotational force to the rotating brush,
- a detachable cover configured to rotatably support the rotating brush, the detachable cover being configured to be detachably coupled to the housing based on being rotated relative to the housing about the rotational axis of the rotating brush,
- a button disposed at the housing and configured to selectively restrict rotation of the detachable cover relative to the housing,
- a plurality of first protrusions disposed at the detachable cover,
- a second protrusion disposed at the housing, and
- a third protrusion disposed at the detachable cover,
- wherein the housing comprises a guide rail arranged along a circumferential direction about the rotational axis and configured to guide rotation of the plurality of first protrusions about the rotational axis,
- wherein the detachable cover includes a guide groove that is defined at an inner surface the detachable cover along the circumferential direction, the guide groove being configured to guide the second protrusion based on the detachable cover being rotated relative to the housing about the rotational axis,
- wherein the button comprises:
- a button portion configured to be pressed by a user, and
- a first blocking portion that extends from the button portion and is configured to restrict rotation of the detachable cover by blocking a rotational route of the third protrusion based on the detachable cover being rotated relative to the housing about the rotational axis, and
- wherein the first blocking portion is configured to, based on the user pressing the button portion, deviate from the rotational route of the third protrusion.

- wherein the housing comprises a guide rail arranged along a circumferential direction about the rotational axis and configured to guide rotation of the plurality of first protrusions about the rotational axis,
- wherein the detachable cover includes a guide groove that is defined at an inner surface the detachable cover along the circumferential direction, the guide groove being configured to guide the second protrusion based on the detachable cover being rotated relative to the housing about the rotational axis,
- wherein the detachable cover comprises a third protrusion that protrudes from the inner surface of the detachable cover and configured to interfere with at least a portion of the button,
- wherein the button comprises:
- a button portion configured to be pressed by a user, and
- a first blocking portion that extends from the button portion and is configured to restrict rotation of the detachable cover by blocking a rotational route of the third protrusion of the detachable cover based on the detachable cover being rotated relative to the housing about the rotational axis,
- wherein the first blocking portion is configured to, based on the user pressing the button portion, deviate from the rotational route of the third protrusion of the detachable cover.
