Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

In order to avoid obscuring the present invention with unnecessary details, it should be noted that only the structures and/or processing steps closely related to the aspects of the present invention are shown in the drawings, and other details not relevant to the present invention are omitted.

In addition, it is also to be noted that the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.

Referring to fig. 1-2, a roller assembly 1 according to a first embodiment of the present invention includes a roller 11, an elastic supporting member 12 wrapped around the roller 11, and a wiper 13 disposed around the elastic supporting member 12. The elastic support 12 is closely fitted to the roller 11 and the wiper 13, respectively, so that the elastic support 12 can rotate in synchronization with the roller 11 and the wiper 13. In other words, relative rotation and slippage between the roller 11 and the elastic supporting member 12 and between the elastic supporting member 12 and the wiper 13 do not occur, and when the driving assembly 3 (see fig. 5) drives the roller 11 to rotate, the roller 11 drives the elastic supporting member 12 to rotate circumferentially, and further drives the wiper 13 to rotate circumferentially for cleaning.

It is to be understood that the reference to discontinuous structures in this application is to continuous structures. By continuous structure, it is meant that the interior of the resilient support 12 is solid and has an integral outer surface. The discontinuous structure means that the inside of the elastic support 12 is discontinuous, and a part of hollow structure exists in the inside, or the outer surface of the elastic support 12 is discontinuous, and at least a part of recess exists in the outer surface, and the like.

Further, the roller 11 is made of rigid material which does not absorb water and is not easy to deform, so that the roller assembly 1 has certain rigidity, and the inside of the roller assembly 1 is not easy to store water, thereby facilitating the cleaning of the roller assembly 1. Elastic support member 12 is discontinuous structure, and for the elasticity material that does not absorb water, can save material, reduces roller assembly 1's cost, prevents simultaneously that elastic support member 12 from absorbing water and the roller assembly 1 that leads to hides the problem of dirty dirt easily, and elasticity discontinuous structure also makes roller assembly 1 can have great rubbish throughput capacity, makes roller assembly 1 can satisfy the strong and clean requirement of easy water of scraping of cleaning simultaneously. In addition, the roller 11 and the elastic supporting part 12 are made of non-water-absorbing materials, so that the roller assembly 1 can be prevented from absorbing water and becoming heavy, the movement is convenient, and the use experience of a user is improved. The wiping piece 13 is made of elastic water-absorbing material, such as cloth fiber or sponge material which can absorb water, or disposable wiping piece 13, so that the wiping piece 13 can carry water to bind impurities, and the cleaning capability is improved.

Further, the material rigidity of the elastic support 12 is smaller than that of the wiper 13, and the radial thickness of the elastic support 12 is larger than that of the wiper 13. In one embodiment, the radial thickness of the resilient support 12 is 6-10mm and the radial thickness of the wiper 13 is 5-7mm. So set up for the thickness of the wiper 13 that can absorb water among the drum assembly 1 is less, the water consumption is little during cleaning work, treat the cleaning face, like ground, be difficult to leave the water mark, and because elastic support element 12's thickness is great, elasticity is great, so when drum assembly 1 meets great size rubbish, can have better rubbish throughput capacity and deformation restorability, drum assembly 1 size and weight before and after the use all change little, improve cooperation precision and user experience between each structure. And after the operation is completed, the drum assembly 1 is dried by evaporation with less moisture remaining therein, so that the drum assembly 1 does not get moldy or smelly. And when the water-absorbing agent is used again after being placed for a period of time, a longer water absorption process is not needed, and the use is convenient. In addition, the radial thickness of the elastic support 12 is set to be larger, so that the elastic ribs 123 and other structures are conveniently arranged between the inner wall 121 and the outer wall 122 of the elastic support 12, and therefore, the large garbage can be extruded with a large deformation amount, and larger garbage passing capacity is obtained.

In other embodiments, the first engaging portion 111 may also be a slot, and the second engaging portion 1211 is a protrusion, that is, a plurality of protrusions extending along an axial direction of the roller 11 are disposed on a side of the roller 11 facing the elastic support 12, and a plurality of slots are correspondingly disposed on the inner wall 121 of the elastic support 12, and the protrusions and the slots are engaged with each other in a one-to-one correspondence. Alternatively, the first and second engaging portions 111 and 1211 are fixed to each other, and the present invention is not limited thereto as long as the roller 11 and the elastic supporting member 12 are tightly connected to each other to keep rotating synchronously. Through setting up first joint portion 111 and second joint portion 1211 for elastic support piece 12 can roll and closely cooperate with the axle, and need not other location structure and supplementary, is favorable to reduction in production cost. Also, the roller 11 and the elastic support 12 may be detachably connected, and may be separately removed and replaced when needed.

Further, the outer wall 122 of the elastic support 12 is in close fitting connection with the inner circumferential wall of the wiper 13.
