Abstract
A mobile cleaner includes a dust housing, an agitator, and a dustpan. The dust housing has a collection opening facing a surface. The agitator is rotatably disposed within the dust housing and is exposed to the surface through the collection opening. The agitator is configured to move foreign material from the floor into the dust housing. The dustpan directs the foreign material moved by the agitator into the dust housing. The dustpan extends around a portion of an outer circumferential surface of the agitator and is configured to rotate independent of the agitator.
Claims19
A mobile cleaner, comprising:
- a body configured to move on a surface;
- and
- a sweep module installed on a lower portion of the body, the sweep module being configured to collect foreign material from the surface,
- wherein the sweep module comprises:
- an agitator configured to rotate and collect the foreign material from the surface;
- a storage space configured to store the foreign material collected by the agitator;
- a dust housing;
- and
- a dustpan configured to direct the foreign material collected by the agitator into the dust housing,
- wherein the dustpan covers a portion of an outer circumferential surface of the agitator,
- wherein the dustpan is configured to rotate independent of the agitator, and
- wherein a rotation axis of the dustpan is positioned on a rotation axis of the agitator.
A mobile cleaner, comprising:
- a dust housing having a collection opening facing a surface that the mobile cleaner moves on;
- an agitator rotatably disposed within the dust housing and exposed to the surface through the collection opening, the agitator configured to be in contact with the surface and configured to rotate and move foreign material on the surface into the dust housing;
- and
- a dustpan installed on the dust housing or the agitator, the dustpan being configured to direct the foreign material moved by the agitator into the dust housing,
- wherein the dustpan extends around a portion of an outer circumferential surface of the agitator and is configured to rotate independent of the agitator,
- wherein the dustpan is coupled to the dust housing, and
- wherein the dustpan covers the portion of the outer circumferential surface of the agitator and portions of opposite side surfaces of the agitator.
A mobile cleaner, comprising:
- a dust housing having a collection opening facing a surface that the mobile cleaner moves on;
- an agitator rotatably disposed within the dust housing and exposed to the surface through the collection opening, the agitator configured to be in contact with the surface and configured to rotate and move foreign material on the surface into the dust housing;
- and
- a dustpan installed on the dust housing or the agitator, the dustpan being configured to direct the foreign material moved by the agitator into the dust housing,
- wherein the dustpan extends around a portion of an outer circumferential surface of the agitator and is configured to rotate independent of the agitator,
- wherein the dust housing comprises:
- a housing assembly having a collection space and a storage space positioned within the housing assembly, the collection opening being disposed at a bottom surface of the housing assembly and fluidly coupled with a lower side of the collection space;
- a partition wall partitioning the collection space and the storage space;
- and
- a storage opening disposed at any one of the housing assembly or the partition wall, the storage opening being configured to direct the foreign material in the collection space into the storage space, and
- wherein the agitator and the dustpan are disposed in the collection space.
