[0024] In order to solve the problem that too many motors are installed in the sweeping machine in the prior art, which leads to increased cost and increased space occupation, the present application provides a sweeping machine cleaning component 1, such as Figure 1 As shown, the sweeping machine cleaning assembly 1 includes a driving device 11, a first rag disc assembly 12 and a second rag disc assembly 13. The driving device 11 is transmission-connected to the first rag disc assembly 12, and the second rag disc assembly 13 is transmission-connected to the first rag disc assembly 12. The driving device 11 is controlled to drive the first rag disc assembly 12 to rotate, and the first rag disc assembly 12 drives the second rag disc assembly 13 to rotate during the rotation. The driving device 11 of the present application directly drives the first rag disc assembly 12 to rotate, and the first rag disc assembly 12 drives the second rag disc assembly 13 to rotate, so that when only one driving device 11 is provided, it can be ensured that the first rag disc assembly 12 and the second rag disc assembly 13 can both work normally, reducing the number of driving devices 11 and also reducing the space occupied by the driving device 11 in the sweeping machine.
[0025] It should be noted that the driving device 11 of the present application is directly connected to the first rag plate assembly 12, and the first rag plate assembly 12 and the second rag plate assembly 13 can be connected through a pulley. At this time, the first rag plate assembly 12 rotates under the drive of the driving device 11, and the first rag plate assembly 12 rotates through the rotation of the belt and the pulley, thereby driving the second rag plate assembly 13 to rotate; the first rag plate assembly 12 and the second rag plate assembly 13 can also be connected by transmission through a sprocket and a chain. At this time, the working principle of the second rag plate assembly 13 is the same as the working principle of driving the second rag plate assembly 13 through the pulley mentioned above, and will not be repeated here. The first rag plate assembly 12 and the second rag plate assembly 13 can also be connected by friction wheel transmission. At this time, the first rag plate assembly 12 and the second rag plate assembly 13 both include friction wheels. During the rotation process, the friction wheel of the first rag plate assembly 12 rubs against the friction wheel of the second rag plate assembly 13, thereby driving the second rag plate assembly 13 to rotate. Of course, the first rag plate assembly 12 and the second rag plate assembly 13 can also be connected by gear transmission. The above is not restrictive and can be configured according to the needs of technical personnel in this field. All of the above are within the protection scope of this application.
[0026] It should also be noted that, the present application is introduced by taking the setting of a first rag plate assembly 12 and a second rag plate assembly 13 as an example, the present application can also be provided with multiple second rag plate assemblies 13, the driving device 11 drives the first rag plate assembly 12 to rotate, and the first rag plate assembly 12 drives the multiple second rag plate assemblies 13 to rotate during the rotation process. The above is not restrictive and can be set according to the needs of technical personnel in this field, and the above are all within the protection scope of the present application.
[0027] This application mainly introduces the example of the first rag plate assembly 12 and the second rag plate assembly 13 connected by gear transmission. In one embodiment, the first rag plate assembly 12 includes a first gear 121, and the second rag plate assembly 13 includes a second gear 131, and the first gear 121 and the second gear 131 are meshed for transmission. Specifically, the first gear 121 and the second gear 131 can both include a gear plate 1310 and an outer gear ring 1315 arranged around the rotation center of the gear plate 1310, and the outer gear ring 1315 of the first gear 121 is meshed with the outer gear ring 1315 of the second gear 131 for transmission. The gear mechanism has stable transmission, reliable operation, compact structure, high efficiency and long service life.
[0028] During the cleaning process, the driving device 11 is controlled to drive the first gear 121 to rotate, and the first gear 121 is meshed with the second gear 131, so that the first gear 121 drives the second gear 131 to rotate during the rotation. Gears are directly set on the first rag plate assembly 12 and the second rag plate assembly 13, and the gear meshing ensures that the driving device 11 directly drives the first rag plate assembly 12 to rotate, and the first rag plate assembly 12 drives the second rag plate assembly 13 to rotate. At this time, the second rag plate assembly 13 can be driven to rotate without additional transmission parts. The above arrangement reduces the arrangement of other transmission parts, reduces the cost, and can also reduce the occupied space of the sweeper cleaning assembly 1.
[0029] In one embodiment, the first rag plate assembly 12 further includes a first rag plate 122, and the second rag plate assembly 13 further includes a second rag plate 132. The first rag plate 122 is arranged at the bottom of the first gear 121, that is, arranged at the side of the first gear 121 facing the ground. The second rag plate 132 is arranged at the bottom of the second gear 131, that is, arranged at the side of the second gear 131 facing the ground. The first rag plate 122 is coaxially arranged and relatively fixed with the first gear 121, and the second rag plate 132 is coaxially arranged and relatively fixed with the second gear 131. The first rag plate 122 and the second rag plate 132 are used to contact the ground to clean the ground. Along the axial direction of the first gear 121, the first rag plate 122 contacts the second rag plate 132 at the meshing position of the first gear 121 and the second gear 131. When the first rag plate 122 and the second rag plate 132 are in direct contact with the ground and clean the dirt on the ground, in order to avoid dead corners between the first rag plate assembly 12 and the second rag plate assembly 13 during cleaning, the first rag plate 122 and the second rag plate 132 can be kept in contact at the opposite meshing position, so that there is no gap between the first rag plate assembly 12 and the second rag plate assembly 13, and there will be no dead corners during cleaning.
[0030] In one embodiment, the outer gear ring 1315 of at least one of the first gear 121 and the second gear 131 is set to a flexible material. The meshing of the gears made of flexible materials can reduce the noise generated by the rotation of the gears, and can also prevent the user from being scratched by the outer gear ring 1315 when touching the outer gear ring 1315. The flexible material of the outer gear ring 1315 can be a silicone material, or a rubber material, and can also be set to other flexible materials according to the needs of those skilled in the art, all of which are within the protection scope of this application.
[0031] In one embodiment, the gear plate 1310 and the outer gear ring 1315 can be an integrated structure. In this case, the gear plate 1310 and the outer gear ring 1315 are integrally injection molded. The gear plate 1310 and the outer gear ring 1315 are set as an integrated structure to reduce the number of molds and the number of installation steps. Of course, the gear plate 1310 and the outer gear ring 1315 can also be set as a separate setting, and the outer gear ring 1315 is installed on the outer peripheral surface of the gear plate 1310. In this case, the outer gear ring 1315 can be, for example, sleeved on the outer peripheral surface of the gear plate 1310. When the outer gear ring 1315 or the gear plate 1310 is damaged, only the damaged outer gear ring 1315 or the gear plate 1310 can be replaced, thereby saving maintenance costs. For the convenience of introduction, the following takes the second gear 131 as an example of including the gear plate 1310 and the outer gear ring 1315 as an example.
[0032] In one embodiment, if Figure 1 As shown in FIG. 1 , the gear plate 1310 of at least one of the first gear 121 and the second gear 131 is a hollow plate body provided with a hollow 1314. The hollow 1314 is provided on the gear plate 1310 to reduce the overall weight of the second gear 131.
[0033] Taking the gear plate 1310 of the second gear 131 as a hollow plate body as an example, in a specific embodiment, the hollow plate body includes an inner plate body 1312 located at the center, an outer plate body 1311 arranged around the inner plate body 1312, and a plurality of ribs 1313. The inner plate body 1312 is coaxially arranged with the outer plate body 1311, and a gap is left between the inner plate body 1312 and the outer plate body 1311, that is, there is a hollow 1314. The plurality of ribs 1313 are arranged at intervals in the gap to connect the inner plate body 1312 and the outer plate body 1311. By adopting the above-mentioned hollow plate body, on the one hand, the outer plate body 1311 can be used to ensure the meshing strength and the inner plate body 1312 can be used to ensure the installation, and on the other hand, the weight reduction can be maximized. Of course, the hollow 1314 can also be set to other forms. For example, the gear plate 1310 is in the form of a disc, and one or more through holes, namely the hollow 1314, are set on the gear plate 1310. The above is not restrictive and can be set according to the needs of technical personnel in this field. The above are all within the protection scope of this application.
[0034] In one embodiment, the driving device 11 includes a motor 111 and a reduction box 112, wherein the motor 111 is drivingly connected to the reduction box 112, and the reduction box 112 is drivingly connected to the first gear 121. Since the first rag plate assembly 12 and the second rag plate assembly 13 need to rotate slowly to ensure the cleaning effect on the ground, and at the same time, the dirt around the first rag plate assembly 12 and the second rag plate assembly 13 can be prevented from being blown away by the rotating rag plates during the slow rotation, the rotation speed of the output shaft of the motor 111 is required to be low speed. In general, the rotation speed of the output shaft of the motor 111 is too fast. In order to meet the low-speed rotation requirements of the first rag plate assembly 12 and the second rag plate assembly 13, a reduction box 112 is provided between the first rag plate assembly 12 and the motor 111. The rotation speed of the output shaft of the motor 111 is reduced through the transmission of the gears in the reduction box 112, and the output shaft of the reduction box 112 is drivingly connected to the first rag plate assembly 12 so that the first rag plate assembly 12 rotates at a low speed. In this embodiment, an integrated motor 111 and a reduction gearbox 112 may be selected.
[0035] In one embodiment, a first magnetic pole is disposed on the output shaft of the reduction box 112, and a second magnetic pole is disposed at the axis of the first gear 121. The first magnetic pole and the second magnetic pole have opposite polarities. The output shaft of the reduction box 112 is engaged with the first rag plate assembly 12 through the magnetic attraction of the first magnetic pole and the second magnetic pole to achieve power transmission. The reduction box 112 and the first gear 121 are connected by magnetic attraction, which can facilitate the subsequent disassembly of the reduction box 112 and the first gear 121, and thus facilitate the maintenance of the reduction box 112 or the first gear 121.
[0036] In one embodiment, if Figure 2 As shown, a concave structure 1221 is provided at the bottom of the first rag plate 122, and a Velcro (not shown in the figure) that can be removed from the first rag plate 122 is provided at the bottom of the first rag plate 122. The Velcro is provided with a hole corresponding to the concave structure 1221, so that the concave structure 1221 is exposed. The Velcro is used to contact the ground and clean the ground. When the Velcro is damaged and cannot be used, it can be directly removed and replaced with a new Velcro. The Velcro is provided with a hole corresponding to the concave structure 1221, which can reduce the use of Velcro and thus reduce the production cost of Velcro.
[0037] It should be noted that the present application is introduced by taking the recessed structure 1221 provided on the first rag tray assembly 12 as an example. Of course, the second rag tray assembly 13 may also be provided with a recessed structure 1221, and a Velcro may be provided correspondingly. In addition, the first rag tray 122 or the second rag tray 132 of the present application may also be a component that can directly clean the floor. When the first rag tray 122 or the second rag tray 132 cannot be used anymore due to dirt or damage, the rag tray may be directly replaced. The above is not restrictive and may be provided according to the needs of those skilled in the art. All of the above are within the protection scope of the present application.
[0038] In summary, the driving device 11 directly drives the first rag plate assembly 12 to rotate, and the first rag plate assembly 12 drives the second rag plate assembly 13 to rotate during the rotation, thereby ensuring that the first rag plate assembly 12 and the second rag plate assembly 13 can work normally when only one driving device 11 is set, while also reducing the number of driving devices 11 and saving the space occupied in the sweeper.
[0039] In addition, the present application also provides a sweeping machine, which has a sweeping machine cleaning component 1 in any of the above-mentioned embodiments, and the sweeping machine also includes a sweeping machine body, and the sweeping machine cleaning component 1 is arranged at the bottom of the sweeping machine body.
