The portable washing apparatus 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

Referring to fig. 1, a portable washing apparatus 100 according to an embodiment of the present invention may include: a housing 10, a driving device 20 and a washing workpiece 30.

Specifically, the driving device 20 may be disposed inside the casing 10, the casing 10 may have an opening 101, an outer circumferential surface of the washing workpiece 30 may protrude from the opening 101 to form a washing action surface 301, the washing action surface 301 may contact with an object to be washed (e.g., clothes, bedding, curtains, etc.), and the washing workpiece 30 may be eccentrically rotated by the driving device 20.

Here, the outer peripheral surface of the washing workpiece 30 may partially protrude from the opening 101, or may entirely protrude from the opening 101. In other words, at least a portion of the outer peripheral surface of the washing workpiece 30 can protrude from the opening 101, and it is only necessary to satisfy the requirement that the washing workpiece can protrude from the opening 101 to serve as the washing action surface 301 which is in direct contact with the workpiece to be washed.

Thus, the height of the washing action surface 301 extending out of the opening 101 (e.g., the distance downward beyond the housing 10 in the up-down direction shown in fig. 1) can be changed along with the eccentric rotation of the washing workpiece 30, so that the contact between the washing action surface 301 and the workpiece to be washed can be switched between pressing and releasing, and the beating of the workpiece to be washed is realized; when the washing action surface 301 rotates, the washing action surface and the to-be-washed piece move relatively in the circumferential direction, so that friction of the to-be-washed piece can be realized, or rubbing can be realized.

The beating action and the rubbing action of the workpiece to be washed are directly combined with each other by the washing workpiece 30, so that the manual rubbing process of a human can be simulated, and the workpiece to be washed can be cleaned. Compared with the ultrasonic non-contact cleaning in the related art, the washing effect of manual scrubbing is better, the user does not directly scrub by hands, but the washing is realized through the portable washing equipment 100, the labor is saved, the abrasion damage to hands is reduced, and the use is simpler and more convenient.

In addition, the washing workpiece 30 directly contacts with the workpiece to be washed, other transmission structures are not needed, the structure is simple, and the size of the portable washing device 100 is favorably reduced. The size of the washing workpiece 30 and the arrangement positions of the washing workpiece 30 and the driving device 20 can be adjusted according to actual requirements, so that the structure is more compact, and the portable washing device 100 is also beneficial to realizing miniaturization. The use and the carrying are more convenient,
