     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     The invention will be further described below in conjunction with the accompanying drawings and specific embodiments. 
     Embodiment 1 
     Referring to  FIG. 1  to  FIG. 3 , a cleaning roller comprises a central shaft  1  capable of rotating, a steam channel  2  and a cleaning layer  3 , wherein the steam channel  2  is provided with a steam inlet  21  and a plurality of steam outlets  22 , the steam inlet  21  is used for communicating with a steam generation device  9 , the plurality of first steam outlets  22  are distributed in an axial direction of the central shaft  1 , the cleaning layer  3  is provided around the central shaft  1 , and steam flowing out from the first steam outlets  22  is diffused outwards through the cleaning layer  3 . 
     Through the above structural arrangement, when the cleaning roller is used, the central shaft rotates to drive the cleaning layer to rotate, so that the cleaning roller can roll to clean the surface of an object to be cleaned. Specifically, steam generated by the steam generation device enters the steam channel via the steam inlet, then flows out of the steam channel via the first steam outlets, and is diffused outwards through the cleaning layer, so that the steam can be diffused to the object to be cleaned, and cleaning water can more evenly adhere to the surface of the object to be cleaned. In this way, the cleaning roller can effectively clean the surface of the object to be cleaned; and the surface of the object to be cleaned will not be too wet, so that safety accidents are avoided. 
     As a preferred implementation of this embodiment, the central shaft  1  is hollow, so that the steam channel  2  is formed in the central shaft  1 . In this way, the steam channel does not need to be arranged separately, so the structure is simple, and the design is ingenious. Further, through holes are formed in a side wall of the central shaft  1  to form the first steam outlets  22 . 
     In this embodiment, referring to  FIG. 4 , the cleaning roller further comprises an inlet sleeve  23 , an inlet through-hole is formed in the side wall of the central shaft  1  to form the steam inlet  21 , the inlet through-hole of the central shaft  1  is sleeved with the inlet sleeve  23 , and support portions  24  are disposed on inner walls of two ends of the inlet sleeve  23 , so that a gap is reserved between the inlet sleeve  23  and the inlet through-hole of the central shaft  1  to form an air inlet passage  25  surrounding the inlet through-hole; and a vent  26  is formed in a side wall of the inlet sleeve  23  and communicates with the steam generation device  9 . 
     The inlet sleeve is arranged to form an air inlet passage; when the cleaning roller is used, steam sequentially passes through the vent, the air inlet passage and the steam inlet to enter the steam channel. In addition, because the inlet sleeve is disposed around the central shaft, that is, the central shaft is able to rotate with respect to the inlet sleeve, when the central shaft rotates (when the cleaning roller works), the inlet sleeve does not rotate to keep the position of the vent unchanged to ensure that the vent communicates with the steam generation device, so that the structure is simple, and the design is ingenious. Wherein, the support portions may be sealing rings and can fulfill a support effect and a sealing effect without exerting an excessive influence on the rotation of the central shaft. Moreover, four inlet through-holes may be configured and distributed in the axial direction of the central shaft. Stop protrusions  106  are disposed on two sides of the inlet sleeve to prevent the inlet sleeve from moving leftwards or rightwards, such that the structural stability is guaranteed.

     Furthermore, support sleeves  4  are disposed between the end shafts  12  and the cleaning layer  3 , the cleaning layer  3  is mounted around the support sleeves  4 , and second steam outlets  41  are formed in side walls of the support sleeves  4  and communicate with the first steam outlets  22 . When the cleaning roller is used, steam flowing out of the steam channel sequentially passes through the first steam outlets and the second steam outlets, and is then diffused outwards through the cleaning layer. The cleaning layer is mounted around the support sleeves, thus being easy to assemble. 
     Specifically, each of the support sleeves  4  comprises a first sleeve  42  and a second sleeve  43 , the first sleeves  42  are sleeved with the second sleeves  43 , and sealing structures are disposed in the first sleeves  42  and the second sleeves  43 . Steam can be prevented, to some extent, from leaking between the support sleeves and the central shaft, so that the reliability of the product is improved. Wherein, the first sleeves and the second sleeves may be clamped and connected with each other. 
     Furthermore, the sealing structures  6  in the second sleeves  43  are sealing plugs  6 , and connection portions  61  extend from the sealing plugs  6  towards the end shafts  12  and are connected to the end shafts  12 . In this way, the second sleeves can be fixed to the central shaft by means of the sealing plugs, which makes the structure simple and reliable. Wherein, the connection portions and the end shafts may be connected in a threaded manner, such that the cleaning roller can be assembled and disassembled easily. 
     In this embodiment, first clamping grooves  13  are formed in outer walls of the end shafts  12 , first clamping blocks  44  are disposed on inner wall of the first sleeves  42 , and the first clamping blocks  44  are clamped in the first clamping grooves  13 , such that the first sleeves are driven to rotate when the central shaft rotates, and the structure is simple and reliable.
