The cleaning apparatus generally includes a spray assembly, a cleaning assembly 201. The spraying assembly sprays cleaning liquid onto the surface to be cleaned, the cleaning assembly 201 typically includes a cleaning tool such as a roller brush and/or a rag, and the cleaning assembly 201 contacts the surface to be cleaned to clean the surface to be cleaned. Some cleaning devices also include a reclamation assembly, which typically includes a vacuum work system for reclaiming debris from the surface to be cleaned to make the surface to be cleaned cleaner.

For convenience of the subsequent description, directions "front" and "rear" are defined with reference to the moving direction of the cleaning apparatus. Directions "up" and "down" are defined with reference to the cleaning device being "up" and the surface to be cleaned being "down". The definition defines the forward direction F of the cleaning device as longitudinal direction and the direction perpendicular to the longitudinal direction as transverse direction, or width direction W.

Referring to fig. 3 to 5, the scraping body 30 is adapted to be disposed adjacent to a cleaning assembly 201 of the cleaning apparatus. More specifically, the scraping body 30 is disposed at a rear side of the cleaning assembly 201. The cleaning assembly 201 of this embodiment is a rolling brush assembly, which can drive the garbage backwards when rotating, and the garbage driven backwards by the rolling brush assembly is blocked by the scraping body 30, and the garbage will move to the recycling assembly along the outer surface 36 of the scraping body 30.

The cleaning assembly 201 extends transversely by a certain length, in order to enable the scraping body 30 to effectively clean the garbage which is driven backwards by the cleaning assembly 201, the transverse extension length of the scraping body 30 can be greater than or equal to that of the cleaning assembly 201, and the cleaning assembly 201 is located within the transverse extension range of the scraping body 30. Therefore, no matter which part of the cleaned component 201 drives the backward garbage, the garbage can move to the recovery component along the outer surface 36 of the scraping body 30, and effective cleaning is realized.

The scraping body 30 comprises a free end 34 opposite the front side for contacting the surface to be cleaned, and the scraping body 30 further comprises a fixed end 35 opposite the rear side adapted for connection to a cleaning device. The scraping body 30 further includes an outer surface 36 extending obliquely upwardly from the free end 34 toward the fixed end 35, the outer surface 36 being configured as a waste guide surface for the scraping body 30, waste being directed along the outer surface 36 into the recycling assembly.

The free end 34 of the scraping body 30 is substantially in contact with the surface to be cleaned when the cleaning device is moved over the surface to be cleaned, so that the function of scraping water and soiling can be effectively achieved. Meanwhile, since the free end 34 of the scraping body 30 contacts with the surface to be cleaned and applies a forward and downward force to the surface to be cleaned, the free end 34 of the scraping body 30 is easily stopped by a threshold or an obstacle such as a brick seam during the movement of the cleaning device, so that the movement of the scraping body 30 and even the cleaning device is difficult.

Example 2

The present embodiment provides a wiping assembly, and the following focuses on the differences of the wiping assembly of the present embodiment from the wiping assembly 100 of embodiment 1.

In embodiment 1, the scraping assembly 100 further includes a connecting mechanism, the connecting mechanism is suitable for movably connecting the cleaning device, and the connecting mechanism can drive the scraping body 30 to move from the second position to the first position under the action of external force, so that the operation is more reliable.

In this embodiment, the scraping body 99 has a fixed end 97 adapted to be connected to a cleaning device and a free end 98, wherein the free end 98 is moved from the second position to the first position when the free end 98 is subjected to an external force.

That is, in the embodiment 1, the external force acts on the connecting mechanism, but in the embodiment, the external force acts directly on the free end 98 of the scraping body 99, since the scraping body 99 is a flexible scraping body and has a certain deformation amount, the free end 98 is elastically deformed by the force, and the free end 98 is bent upward relative to the fixed end 97 to pass over the obstacle. The structure is simpler.

Both ends of the wiper body 99 are formed as a fixed end 97 and a free end 98, respectively, and a groove 96 is further provided between both ends of the wiper body 99. By providing the scraping body 99 with the groove, the scraping body 99 is more easily deformed, and thus when encountering an obstacle, the scraping body is more easily moved to the second position, and thus the obstacle can be more easily passed over.

The slot 96 may extend in the width direction W of the cleaning device, that is, the slot 96 may extend in substantially the same direction as the axis of deformation of the free end 98 relative to the fixed end 97, such that the free end 98 is more easily moved to the second position.

The wiper 99 has a first end surface 95 and a second end surface 94 opposite to each other, wherein the first end surface 95 is located in front of the second end surface 94 with the moving direction of the cleaning device as the front side, and the groove 96 is disposed on the second end surface 94. Since the scraping body 99 is lifted by being deformed from the bottom to the top and the groove 96 is formed at the second end surface 94 opposite to the bottom, the scraping body 99 is more easily deformed and lifted, and thus the obstacle can be easily overcome.
