- the end cover 225 may support the inserted brush unit 223 in the axial direction of the rotating rod 221 to prevent the brush unit 223 from being separated from the brush slit 224.
- the brush assembly 220 may further include a connection pin 226 as shown in 6.
- the connecting pin 226 is elastically supported by the elastic member 227 toward the inner side of the rotating rod 221 and passes through the through hole 222f formed in the end cover 225 in the axial direction of the rotating rod 221. It may be made to protrude.
- the connecting pin 226 may include a locking part 226g that is engaged with the inner surface of the end cover 225, and may be positioned so as not to be completely separated from the through hole 222f by the elastic member 227. The connecting pin 226 is pushed into the end cover 225 when the brush assembly 220 is mounted on the suction unit, and is protruded again by an elastic force when the brush assembly 220 is inserted into the end cover 225. Can be achieved.
- the plurality of covers 222 may each have a shape in which at least two spiral shapes are combined in the axial direction of the rotating rod 221.
- the brush slit 224 may also be formed to extend in a shape that is deflected at least once on the outer circumferential surface of the rotating rod 221.
- FIG. 8 is a perspective view illustrating a state in which the brush units 223 shown in FIG. 6 are separately manufactured.
- the brush units 223 may be easily manufactured in a form extending in one direction in a separate manufacturing process.
- the brush unit 223 may be made of an elastic material so that the brush slit 224 is easily inserted into the brush slit 224 even when the brush slit 224 is not formed in a straight line.
- the brush unit 223 may be inserted into the brush slit 224 having a shape that is bent while being deformed. Accordingly, the brush unit 223 corresponding to various shapes does not need to be manufactured separately, and the brush unit 223 may be manufactured according to a process method capable of densely arranging the hair.
- the brush assembly 220 may be formed in a shape having various brush arrangements as well as the shape of the brush assembly 220 shown in FIG. 6.
- the present invention is applicable not only to robot cleaners, but also to brushes of various types of vacuum cleaners.
