Abstract
A nozzle part and a robot cleaner including same are disclosed. A nozzle part according to various embodiments of the present invention comprises: a brush for collecting waste such as hair; and a removing member for removing the waste, such as hair, that is stuck to the brush. The removing member more quickly rotates than the brush in the same direction to remove the waste, such as hair, that is stuck to the brush. Therefore, the waste such as hair can be easily collected, removed and captured. Thus, user convenience can be improved.
Claims12
A nozzle assembly, comprising:
- a frame;
- a roller rotatably coupled to the frame to extend in an extension direction;
- and
- a removal assembly located adjacent to the roller, and rotatably coupled to the frame with respect to the roller,
- wherein the removal assembly comprises:
- an extension wall extending along the extension direction of the roller, and located adjacent to an outer circumference of the roller to partially cover the outer circumference of the roller;
- and
- a support part located at an end of the extension wall, and rotatably coupled to the frame
- wherein the support part defines a hollow, and the roller passes therethrough, and an inner circumference of the support frame surrounding the hollow has a circular cross section,
- wherein the nozzle assembly further comprises:
- a main gear coupled to the roller to rotate together with the roller;
- and
- a sub-gear coupled to the main gear, and
- wherein the removal assembly further comprises:
- teeth positioned on the inner circumference of the support part and coupled to the sub-gear.
A robot cleaner, comprising:
- a body;
- a dust bin detachably coupled to the body, and having a space defined therein;
- a nozzle housing detachably coupled to the body, an inner space of which communicates with the space of the dust bin;
- and
- a nozzle assembly accommodated in the nozzle housing,
- wherein the nozzle assembly comprises:
- a frame coupled to the nozzle housing;
- a roller rotatably coupled to the frame, having a circular cross section, extending in an extension direction, and partially exposed to an outside through an opening of the nozzle housing;
- and
- a removal assembly located adjacent to the roller to extend in the extension direction of the roller, and rotatably coupled to the frame with respect to the roller at a radial outer side of the roller,
- wherein the removal assembly comprises:
- an extension wall extending along the extension direction of the roller, and located adjacent to an outer circumference of the roller to cover a portion of the outer circumference of the roller;
- and
- a support part located at an end of the extension wall, and rotatably coupled to the frame, and
- wherein:
- the support part defines a hollow along the extension direction of the roller, the roller passing therethrough,
- teeth are provided on an inner circumference of the support part surrounding the hollow, and
- the removal assembly comprises a gear train coupled to the roller, and coupled to the teeth of the inner circumference of the support part.
