As shown in fig. 1 to 3, the hand-held cleaning device 10 includes a housing 100, and a dust suction motor 200, a roller brush 700, and a driving motor 300 within the housing 100.

The case 100 has a longitudinal section taken along a length direction thereof and a cross section taken along a width direction thereof, and the longitudinal section and the cross section are perpendicular to each other.

The dust collection motor 200 is connected to the dust collection box 400, and is used for driving the dust collection box 400 to collect dust.

The roller brush 700 extends along a lateral direction or a length direction of the cleaning apparatus to clean a surface of the cleaning object. The transmission motor 300 is connected with the rolling brush 700 and is used for driving the rolling brush 700 to rotate.

The extension directions of the dust suction motor 200 and the driving motor 300 are parallel, and extend along the length direction of the housing 100.

The roll brush 700 may include a roll core 701, and the roll core 701 may have a long bar shape extending along a length direction of the housing 100. When the roller brush 700 cleans the object to be cleaned, the roller core 701 may spin or vibrate with respect to the surface of the object to be cleaned, so as to scrape off hairs remaining on the surface of the object to be cleaned through the rotating motion or vibration.

As shown in fig. 6 and 7, the rolling brush 700 is located obliquely below the driving motor 300 in the vertical direction, and the rolling brush 700 does not overlap with the projection of the driving motor 300 on the longitudinal section of the housing 100. The roller brush 700 and the driving motor 300 are not in the same plane, whether in a horizontal plane or in a vertical plane perpendicular to the horizontal plane. The presence of the roller brush 700 and the drive motor 300 in a two-dimensional space allows for a more compact arrangement of the roller brush 700 and the drive motor 300, providing for a smaller size of the handheld cleaning appliance 10.

As shown in fig. 6 and 7, the rolling brush 700 is located obliquely below the dust suction motor 200 in the vertical direction, and the rolling brush 700 does not overlap with the projection of the dust suction motor 200 on the longitudinal section of the housing 100. The rolling brush 700 and the dust collection motor 200 are also in a two-dimensional space, and the whole structure is more compact.
