[0027] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0028] Please refer to the attached Figure 1-7 As shown, a floor brush assembly provided by an embodiment of the utility model includes a floor brush body 10, wherein the floor brush body 10 includes a floor brush housing 11, a roller brush assembly 13 and a drive motor assembly 12, wherein the drive motor assembly 12 is fixedly connected to one side of the brush housing via a side connecting arm 14, and the roller brush assembly 13 is detachably connected to the floor brush housing 11 and is transmission-connected to the drive motor assembly 12.

[0029] A guide wheel 20 is provided on one side of the floor brush body 10. It is understandable that in other embodiments, the guide wheel 20 can be provided on both sides of the floor brush body 10. The guide wheel 20 is used to prevent the side wall of the floor brush body 10 from completely contacting and rubbing against the wall when the floor brush assembly cleans the corners. Therefore, it has the function of smooth guidance and reducing the edge resistance. At the same time, when there are steps or obstacles on the wall during edge cleaning, the guide wheel 20 can also be used to cross the steps or obstacles to avoid damaging the floor brush body 10 (floor brush housing 11).

[0030] The floor brush body 10 is provided with a raised mounting seat 15 near the front part of the side where the guide wheel 20 is provided, and a groove 16 is provided in the middle of the mounting seat 15, and the groove 16 is used to accommodate the guide wheel 20, and when the guide wheel 20 is provided in the groove 16, at least the front side and the outer side thereof extend out of the groove 16, and the mounting seat 15 is provided with mounting holes 17 on both upper and lower sides of the groove 16, and also includes a wheel shaft 23, and the wheel shaft 23 is provided on both upper and lower sides of the guide wheel 20 and installed in the corresponding mounting holes 17. In this embodiment, the mounting seat 15 is provided at the corner where the side connecting arm 14 is connected to the drive motor assembly 12. The side wall of the side connecting arm 14 is flush with the side wall of the floor brush housing 11 on its side, and the side wall of the mounting seat 15 is flush with the side wall of the side connecting arm 14, so that except for the guide wheel 20, the side wall of the floor brush body 10 on this side presents a flat plane effect as a whole, making the edge cleaning effect more obvious.

[0031] Specifically, the middle part of the guide wheel 20 is provided with an axial hole 25 which passes through the upper and lower sides, and the wheel axle 23 is passed through the axial hole 25. Optionally, the guide wheel 20 includes a hard core wheel 22 located inside and a soft outer wheel 21 located outside, and the soft outer wheel 21 wraps the hard core wheel 22, wherein the hard core wheel 22 can be made of hard plastic, and the soft outer wheel 21 can be made of soft plastic. In order to facilitate the setting of the axial hole 25 and the tight fit between the axial hole 25 and the wheel axle 23, the hard core wheel 22 needs to be made of hard material so that there is sufficient connection strength between them; the soft outer wheel 21 has a certain buffering effect when the guide wheel 20 contacts the wall or other obstacles through the soft outer wheel 21 during use, so the use effect is better. The hard core wheel 22 is provided with a plurality of spaced limiting protrusions 26, and the soft outer wheel 21 is provided with a plurality of corresponding limiting grooves 27 at positions corresponding to the limiting protrusions 26. The limiting protrusions 26 and the limiting grooves 27 are adaptively nested and connected. Through the matching connection between the limiting protrusions 26 and the limiting grooves 27, it is difficult for the hard core wheel 22 and the soft outer wheel 21 to move out of position. The mounting hole 17 is set as a smooth hole wall, and the outer wall of at least one end of the wheel shaft 23 is provided with a knurling structure 24. The knurling structure 24 can increase the friction between the wheel shaft 23 and the smooth hole wall, thereby realizing relative sliding during installation, and ensuring sufficient friction between each other after installation to prevent the wheel shaft 23 from automatically sliding out of the mounting hole 17.

[0032] During installation, first install the guide wheel 20 into the groove 16 on the mounting seat 15, and align the shaft hole 25 on the guide wheel 20 with the mounting hole 17 on the mounting seat 15, and then insert the wheel shaft 23 from the outside of the mounting hole 17 on one side of the mounting seat 15 and pass through the shaft hole 25 and the mounting hole 17 on the other side in sequence. It should be noted that if the wheel shaft 23 is only provided with a knurled structure 24 at one end, the end of the wheel shaft 23 without the knurled structure 24 can be placed in front for the perforation operation during installation, and preferably the end of the wheel shaft 23 provided with the knurled structure 24 can be controlled to be installed at the lower end, so as to ensure that the wheel shaft 23 is less likely to fall naturally from the mounting hole 17. When disassembling, it is only necessary to push the wheel shaft 23 out of each hole, which will not be described in detail here.

[0033] This embodiment further provides a cleaning device, the cleaning device comprising a floor brush assembly, the floor brush assembly being configured as the floor brush assembly described above. Specifically, the cleaning device is configured as a floor scrubber.

[0034] To sum up, in the floor brush assembly of the present invention, the guide wheel 20 is installed on the mounting base 15 outside the floor brush body 10. When the guide wheel 20 is damaged or falls off during daily use, the user can directly replace it with a new guide wheel 20 without disassembling the floor brush body 10, thereby improving the user experience.

[0035] The cleaning device of the utility model has the same beneficial effects because the above-mentioned floor brush assembly is applied.

[0036] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
