Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present application, "multiple" means at least two, such as two, three, etc., unless otherwise clearly and specifically defined. The embodiments described below with reference to the drawings are exemplary and are intended to be used to explain the present application, and cannot be understood as limiting the present application.

[0039] As shown in Figures 1-3, a cleaning device according to one embodiment of the present application includes a body 1 and a floor brush 2 connected to the body 1. A suction hose 11 and a rotating shaft 12 are provided at one end of the body 1 near the floor brush 2, wherein the body 1 is rotatably connected to the floor brush 2 via the rotating shaft 12. The floor brush 2 includes a floor brush housing, which is provided with a roller brush 24 and a sewage suction port 25. During cleaning, dirt on the floor is swept by the roller brush 24 and the sewage suction port 25, and the dirt is sucked into the floor brush 2 through the sewage suction port 25. A sewage suction pipe 26 is also provided on the floor brush housing. The sewage suction port 25 is fluidically connected to the suction hose 11 on the body 1, and dirt is sucked into a recovery tank (not shown) on the body 1 through the sewage suction pipe 26 and the suction hose 11.

[0040] As shown in Figures 3 to 5, the floor brush housing includes a floor brush upper cover 21 and a floor brush lower cover 22 fixedly connected to the floor brush upper cover 21. The floor brush upper cover 21 and the floor brush lower cover 22 enclose an installation chamber 23 for installing components, and the roller brush 24 is arranged outside the installation chamber 23. A rib 211 is provided on the connection surface between the upper floor brush cover 21 and the lower floor brush cover 22 (i.e., the contact surface with the lower floor brush cover 22 during installation), and a groove 221 is provided on the connection surface between the lower floor brush cover 22 and the upper floor brush cover 21 (i.e., the contact surface with the upper floor brush cover 21 during installation). The rib 211 and the groove 221 extend along the connection surface between the upper floor brush cover 21 and the lower floor brush cover 22, respectively, thereby surrounding the installation chamber 23. A sealing member such as a soft rubber strip (not numbered in the figure) is also provided in the groove 221. During installation, the rib 211 on the upper floor brush cover 21 snaps into the groove 221 on the lower floor brush cover 22, and the rib 211 abuts against the soft rubber strip, thereby achieving a sealing effect. Because the rib 211 and the groove 221 surround the installation chamber 23, the waterproof effect of the installation chamber 23 can be greatly improved, thereby protecting the components in the installation chamber 23.

[0041] As shown in Figures 3, 5 and 6, the installation chamber 23 is provided with electrical components such as an electrolytic water sterilization device 3 and a water pump 31. A rotating shaft 12 is provided on both sides of the body 1 near one end of the floor brush 2. The rotating shaft 12 is hollow and one end of the rotating shaft 12 extends into the installation chamber 23, and the rotating shaft 12 is connected to the installation chamber 23. Wires, water pipes, etc. enter the installation chamber 23 from the body 1 through the rotating shaft 12, thereby connecting components such as the control circuit board and the clean water tank on the body 1 with the components in the floor brush installation chamber 23. Specifically, the outer wall of the floor brush housing is provided with mounting holes 4 on both sides of the body 1. Two rotating shafts 12 are respectively inserted into the two mounting holes 4 and are rotatably connected to the mounting holes 4. During actual use, when the floor brush 2 is exposed to water, although there is a good sealing structure between the floor brush upper cover 21 and the floor brush lower cover 22, water may still enter the installation chamber 23 from the installation hole 4 on the outer wall of the floor brush 2, so there is still a risk of water entering the interior of the floor brush 2. In this embodiment, a water retaining ring 121 is further provided on the side of the rotating shaft 12 close to the floor brush housing relative to the installation hole 4. The water retaining ring 121 is arranged around the outer wall of the rotating shaft 12. The water retaining ring 121 can be concave in the outer wall of the rotating shaft 12 or convex in the outer wall of the rotating shaft 12. When water flows into the floor brush housing from the installation hole 4, and when the water flows along the rotating shaft 12 into the installation chamber 23, the water retaining ring 121 can block the water flow along the axial direction of the rotating shaft 12, thereby blocking the water flow from entering the installation chamber 23, thereby further improving the waterproof ability of the installation chamber 23.

[0042] As shown in Figure 6, the water retaining ring 121 is integrally formed with the rotating shaft 12. Of course, the water retaining ring 121 can also be set as an independent component and then installed on the rotating shaft 12 during the later assembly. The number of water retaining rings 121 can be set to multiple. In this embodiment, there are two water retaining rings 121 on each rotating shaft 12. A diversion chamber 5 is also provided on the lower cover 22 of the floor brush. The part of the rotating shaft 12 with the water retaining ring 121 is located in the diversion chamber 5 or above the diversion chamber 5; when the water flow is blocked by the water retaining ring 121, the water flow flows downward along the water retaining ring 121, and can thus flow into the diversion chamber 5. There is a vertical water retaining wall between the diversion chamber 5 and the installation chamber 23, so that the water in the diversion chamber 5 will not flow into the installation chamber 23. It is preferred to arrange the diversion chamber 5 between the mounting hole 4 and the mounting chamber 23, so that when water enters the floor brush housing from the mounting hole 4, it can flow directly into the diversion chamber 5, or be blocked by the water retaining ring 121 and flow into the diversion chamber 5, thereby preventing water from entering the mounting chamber 23 and improving the waterproofness of the mounting chamber 23. In other embodiments not shown in the figures, the diversion chamber 5 can also be arranged inside the mounting chamber 23, and the diversion chamber 5 is located on the side of the mounting chamber 23 close to the mounting hole 4, so that water can only flow into the diversion chamber 5 and will not flow into other positions in the mounting chamber 23.

[0043] In this embodiment, a portion of the connecting surface of the floor brush upper cover 21 and the floor brush lower cover 22 surrounds the outer wall of the guide chamber 5. As shown in Figures 3 and 5, part of the groove 221 extends along the outer wall of the guide chamber 5, so that the connecting surface of the floor brush upper cover 21 and the floor brush lower cover 22 can bypass the top of the mounting hole 4. This arrangement can make the mounting hole 4 partially located on the floor brush upper cover 21 and partially located on the floor brush lower cover 22. The mounting hole 4 is formed by the floor brush upper cover 21 and the floor brush lower cover 22, which facilitates production and installation of the rotating shaft 12 to the floor brush 2.

[0044] As shown in Figures 5, 8, and 9, a diversion hole 51 is provided on the bottom wall of the floor brush lower cover 22, which is in fluid communication with the diversion chamber 5. Water in the diversion chamber 5 can flow out of the diversion hole 51 to the outside of the floor brush housing. When the floor brush housing is exposed to water, the sealed connection between the rib 211 on the floor brush upper cover 21 and the groove 221 on the floor brush lower cover 22, as well as the arrangement of the water retaining ring 121 and the diversion chamber 5, can effectively prevent water from entering the installation chamber 23. In actual use, the user may sometimes place the floor brush 2 in a pool of accumulated water for rinsing, or invert the cleaning device, causing the water at the bottom of the floor brush housing to flow into the installation chamber 23 along the diversion hole 51. In order to further improve the waterproof effect, in this embodiment, a water retaining plate 6 is also connected to the bottom wall of the floor brush lower cover 22. The water retaining plate 6 can be detachably mounted on the floor brush lower cover 22 by bolts. The water baffle 6 covers the guide hole 51, and is provided with a water guide groove (labeled 61 and 62) in fluid communication with the guide hole 51, and the water guide groove extends in the horizontal direction. A leakage hole 621 is also provided at one end of the water guide groove away from the guide hole 51. After the water flows out of the guide hole 51, it enters the water guide groove, then flows along the water guide groove, and finally flows out of the leakage hole. On the contrary, the water outside the floor brush housing needs to enter the water guide groove from the leakage hole, then flow along the water guide groove to the guide hole 51, and then enter the guide chamber 5 from the guide hole 51. Therefore, the provision of the water baffle 6 and the water guide groove effectively blocks external water from flowing into the guide hole 51 to a certain extent, thereby blocking external water from entering the installation chamber 23, thereby improving the sealing effect.

[0045] To further enhance the sealing effect, as shown in Figures 8 and 9, in this embodiment, the water baffle 6 is arranged as a whole at an angle, and the guide hole 51 is located at a higher point on the water baffle 6. Each guide hole 51 is matched with two water guide grooves, one of which is located above the other. The higher water guide groove is the first water guide groove 61, and the lower water guide groove is the second water guide groove 62. The end of the first water guide groove 61 away from the guide hole 51 is provided with a first leakage hole 611, and the first leakage hole 611 fluidly connects the first water guide groove 61 and the second water guide groove 62. The end of the second water guide groove 62 away from the first leakage hole 611 is provided with a second leakage hole 621. Therefore, water needs to flow horizontally in the water guide groove in a circuitous manner to reach the guide hole 51 or the second leakage hole 621. Because the water baffle 6 is arranged as a whole at an angle, it effectively blocks external water from flowing into the guide hole 51.

[0046] As shown in FIG10 , the sewage suction pipe 26 is integrally formed with the floor brush lower cover 22, and the sewage suction pipe 26 is not in fluid communication with the installation chamber 23. Therefore, external water will not enter the installation chamber 23 from the connection between the sewage suction pipe 26 and the floor brush lower cover 22, and dirty water sucked up from the sewage suction pipe 26 will not enter the installation chamber 23 from the connection between the sewage suction pipe 26 and the floor brush lower cover 22. Preferably, the floor brush upper cover 21 is also integrally formed, so that the installation chamber 23 has an excellent waterproof effect, can withstand water spray, and improve the quality of the cleaning equipment.

[0047] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
