[0052] Please refer to Figures 1 to 3 As shown, the wet floor brush 10 provided in an embodiment of the present invention includes a floor brush bottom shell 100, a roller brush cover plate 200, and a first sealing structure 400 disposed between the roller brush cover plate 200 and the floor brush bottom shell 100. The floor brush bottom shell 100 is provided with a floor suction port 110. The roller brush cover plate 200 is fixedly installed on the floor brush bottom shell 100 through a connection structure 300, and the roller brush cover plate 200 and the floor brush bottom shell 100 are buckled to form a sewage suction cavity 120 for accommodating the roller brush 101. The roller brush cover plate 200 is further provided with a sewage discharge port 210 for communicating with the sewage pipeline of the floor brush. The sewage discharge port 210 is communicated with the floor suction port 110 through the sewage suction cavity 120. The first sealing structure 400 is used to seal the assembly gap between the roller brush cover plate 200 and the floor brush bottom shell 100.

[0053] It can be understood that the space between the sewage suction cavity 120 and the sewage discharge port 210 constitutes the sewage suction channel of the floor brush. The first sealing structure 400 seals the assembly gap between the roller brush cover plate 200 and the floor brush bottom shell 100, that is, seals the sewage suction channel to prevent sewage from leaking out of the sewage suction channel and avoiding the risk of sewage contacting the electrical components of the floor brush.

[0054] The wet floor brush 10 according to the embodiment of the present invention uses the first sealing structure 400 to seal the assembly gap between the roller brush cover plate 200 and the floor brush bottom shell 100, and fixes and installs the roller brush cover plate 200 on the floor brush bottom shell 100 through the connection structure 300, thereby forming a closed, tight and reliable suction channel, effectively preventing sewage leakage, and avoiding the risk of sewage damaging electrical components.

[0055] The structural form of the connection structure 300 can be various. Refer to Figure 2 , as an implementable manner, the connection structure 300 includes a clamping groove 310 and a clamping hook 320 respectively and correspondingly arranged on the roller brush cover plate 200 and the floor brush bottom shell 100. And / or, the connection structure 300 includes screwing components correspondingly arranged on the roller brush cover plate 200 and the floor brush bottom shell 100. It can be understood that the clamping groove 310 can be arranged on the roller brush cover plate 200, and the clamping hook 320 is correspondingly arranged on the floor brush bottom shell 100 corresponding to the clamping groove 310. Or the clamping groove 310 is arranged on the floor brush bottom shell 100, and the clamping hook 320 is correspondingly arranged on the roller brush cover plate 200 corresponding to the clamping groove 310. And the screwing components correspondingly arranged on the roller brush cover plate 200 and the floor brush bottom shell 100 can be a threaded through-hole seat 331 arranged on the roller brush cover plate 200 and a threaded fixing seat 332 arranged on the floor brush bottom shell 100. A screw is passed through the threaded through-hole on the threaded through-hole seat 331, and the screw is tightly connected to the threaded fixing hole on the threaded fixing seat 332. Or, the screwing components can also be threaded through-hole seats correspondingly arranged on the roller brush cover plate 200 and the floor brush bottom shell 100. A bolt is sequentially passed through the threaded through-holes of the threaded through-hole seats of the roller brush cover plate 200 and the floor brush bottom shell 100, and a nut is sleeved and tightened. The connection structure 300 of this embodiment has a simple structure, making the installation of the roller brush cover plate 200 and the floor brush bottom shell 100 more convenient.

[0056] The structural form of the first sealing structure 400 can be various. Refer to Figure 2 , as an implementable manner, the first sealing structure 400 includes a sealing stop groove 410 and a sealing stop rib 420 that are mutually engaged. The sealing stop groove 410 is arranged on one of the roller brush cover plate 200 and the floor brush bottom shell 100, and the sealing stop rib 420 is correspondingly arranged on the other of the roller brush cover plate 200 and the floor brush bottom shell 100 corresponding to the sealing stop groove 410. As in Figure 2 the shown embodiment, the sealing stop groove 410 is arranged on the roller brush cover plate 200, and the sealing stop rib 420 is correspondingly arranged on the floor brush bottom shell 100 corresponding to the sealing stop groove 410. Through the mutually engaged sealing stop groove 410 and sealing stop rib 420, the penetration of water can be effectively blocked, thereby achieving a good sealing and water-stop effect.

[0057] Refer to Figure 2, in one embodiment, the sealing spigot groove 410 is a groove with a U-shaped cross-section. The U-shaped sealing spigot groove 410 enables the sealing spigot rib 420 to fit tightly within the groove when engaged, and to a certain extent increases the travel distance of water penetration. Thereby further improving the sealing and water-stopping effect. Further, the first sealing structure 400 further includes a sealing washer 430, and the sealing washer 430 is disposed within the sealing spigot groove 410. When the roller brush cover plate 200 is assembled with the floor brush bottom shell 100, the sealing spigot rib 420 is engaged within the sealing spigot groove 410, and under the external pressing force, the sealing washer 430 expands under force, thereby being able to better seal the assembly gap between the roller brush cover plate 200 and the floor brush bottom shell 100 and prevent water within the dirt suction channel from leaking outwards.

[0058] See Figure 1 , as an implementable manner, the wet floor brush 10 further includes a clean water tank 500 and a water path assembly 600 communicating with the clean water tank 500. The water path assembly 600 is used to divert the water in the clean water tank 500 to the dirt suction cavity 120. By diverting the water in the clean water tank 500 to the dirt suction cavity 120 through the water path assembly 600, water can be sprayed onto the roller brush 101 when the roller brush 101 is scrubbing the floor, improving the cleaning ability of the floor brush. In one embodiment, the water path assembly 600 includes a water spraying joint 610, a water pump 620, and an adapter seat 630. The water spraying joint 610 is disposed on the roller brush cover plate 200 for spraying water onto the roller brush 101. The water pump 620 is disposed on the floor brush bottom shell 100 and has an inlet and an outlet. The outlet of the water pump 620 is connected to the water spraying joint 610 through a water pipe. The adapter seat 630 is disposed on the floor brush bottom shell 100 and has a water outlet end and a water inlet end. The water outlet end of the adapter seat 630 is connected to the inlet of the water pump 620 through a water pipe, and the water inlet end of the adapter seat 630 is connected to the clean water tank 500. The water supply path of the water path assembly 600 is that the water pipe sequentially connects the adapter seat 630, the water pump 620, and the water spraying joint 610, thereby diverting the water in the clean water tank 500 to the dirt suction cavity 120. The structure of the water path assembly 600 is simple and the connection is convenient. Compared with the traditional method of using ultrasonic welding for the water path and the water spraying head on the roller brush window cover, it greatly reduces the product scrap rate caused by ultrasonic welding.

[0059] See Figure 1, in one embodiment, the number of the water spray joints 610 is two, and the two water spray joints 610 are respectively arranged at both ends of the roller brush cover plate 200 corresponding to both ends of the roller brush 101. The waterway assembly 600 further includes a tee joint 640. The outlet of the water pump 620 is connected to the first port of the tee joint 640 through a first water pipe 641, and the two water spray joints 610 are respectively connected to the second port and the third port of the tee joint 640 through two second water pipes 642. By providing two water spray joints 610, the uniformity of water spraying on the roller brush 101 can be improved, and the phenomenon that some areas of the roller brush 101 are not sprayed with water can be avoided. By connecting the water pump 620 and the two water spray joints 610 through the tee joint 640, the layout of the waterway assembly 600 can be made simpler, and the structure of the wet floor brush 10 can be made more compact. It can be understood that the number of the water spray joints 610 is not limited to one or two. The number of the water spray joints 610 can also be three, four or even more. When the number of the water spray joints 610 is three, a four-way joint can be used to connect the water pump 620 and the three water spray joints 610.

[0060] See Figure 1 and Figure 3 , as an implementable manner, the wet floor brush 10 further includes a floor brush bottom plate 700. The floor brush bottom plate 700 is buckled to the bottom of the floor brush bottom shell 100, and the tee joint 640 is arranged between the floor brush bottom plate 700 and the floor brush bottom shell 100. The end of the first water pipe 641 far away from the water pump 620 passes through the floor brush bottom shell 100 and is connected to the first port, and the end of each second water pipe 642 far away from the tee joint 640 passes through the floor brush bottom shell 100 and is connected to the water spray joint 610. By arranging the tee joint 640 between the floor brush bottom plate 700 and the floor brush bottom shell 100, the tee joint 640 is separated from the electrical components installed inside the floor brush bottom shell 100, and the electrical components installed in the floor brush bottom shell 100 are prevented from being damaged due to water leakage easily caused by the large number of water pipes connected to the tee joint 640.

[0061] See Figure 2 and Figure 3 , in one embodiment, the wet floor brush 10 further includes a floor brush upper shell 800. The floor brush upper shell 800 is covered on the floor brush bottom shell 100, and a space for avoiding the water spray joint 610 is reserved between the floor brush upper shell 800 and the roller brush cover plate 200. It can be understood that the space between the floor brush upper shell 800 covered on the floor brush bottom shell 100 can be used to arrange the electrical components and other components of the floor brush, etc. Further, the wet floor brush 10 further includes a second sealing structure 900. The second sealing structure 900 is arranged between the floor brush upper shell 800 and the floor brush bottom shell 100, and between the floor brush upper shell 800 and the roller brush cover plate 200. The second sealing structure 900 is used to seal the assembly gap between the floor brush upper shell 800 and the floor brush bottom shell 100, and the second sealing structure 900 is also used to seal the assembly gap between the floor brush upper shell 800 and the roller brush cover plate 200.

[0062] The structural form of the second sealing structure 900 can be various. Refer to Figure 2 and Figure 3 , in one embodiment, the second sealing structure 900 includes a first waterproof partition 910 and a second waterproof partition 920. The first waterproof partition 910 is arranged on the floor brush bottom shell 100 and abuts against the floor brush upper shell 800. A sealing rib 911 is provided on the surface of the first waterproof partition 910 opposite to the floor brush upper shell 800, and a sealing groove 810 that cooperates with the sealing rib 911 is provided on the surface of the floor brush upper shell 800 opposite to the waterproof partition. The second waterproof partition 920 is arranged on the floor brush upper shell 800, and the roller brush cover plate 200 is provided with a waterproof groove 220 corresponding to the second waterproof partition 920, and the second waterproof partition 920 is clamped in the waterproof groove 220.

[0063] Through the first waterproof partition 910 and the cooperating sealing groove 810, as well as the second waterproof partition 920 and the cooperating waterproof groove 220, the area where the water spraying joint 610 is located between the floor brush upper shell 800 and the roller brush cover plate 200 is effectively sealed, avoiding the risk of water seepage due to water leakage at the connection of the water spraying joint 610, thereby effectively isolating the easily leaky part of the water path from the internal components of the floor brush bottom shell 100 and reducing the risk of water overflow damaging the components.

[0064] An embodiment of the present invention also provides a cleaning device, including the wet floor brush 10 described in any of the above solutions. The cleaning device can be a vacuum cleaner or a cleaning machine, etc. During specific use, the sewage pipe of the wet floor brush 10 can be connected to the suction pipe of the vacuum cleaner or the cleaning machine.
