[0050] Please refer to Figure 1 and Figure 2 As shown, the floor brush housing 10 provided in an embodiment of the present invention includes a floor brush bottom shell 100 and a roller brush cover plate 200. The roller brush cover plate 200 is fixedly installed on the floor brush bottom shell 100 through a connection structure 400, and the roller brush cover plate 200 and the floor brush bottom shell 100 are buckled to form a first cavity 110 and a second cavity 120 that are independent of each other and isolated from each other. The first cavity 110 is used to accommodate the lighting component 500, and the second cavity 120 is used to install the roller brush 20.

[0051] The floor brush housing 10 of the embodiment of the present invention fixedly installs the roller brush cover plate 200 on the floor brush bottom shell 100 through the connection structure 400, forming the mutually independent and isolated first cavity 110 and second cavity 120. Thus, the risk of water leakage from the second cavity 120 where the roller brush 20 is located into the first cavity 110 is effectively avoided, and further, the lighting component 500 can be protected from being damaged, ensuring the normal operation of the lighting component 500. Therefore, the floor brush housing 10 of the embodiment of the present invention can be applied to wet cleaning devices such as wet vacuum cleaners.

[0052] Combined Figure 3 As shown, as an implementable manner, the floor brush housing 10 further includes a sealing structure 300, which is disposed between the roller brush cover plate 200 and the floor brush bottom shell 100 and is used to seal the assembly gap between the roller brush cover plate 200 and the floor brush bottom shell 100. Through the sealing structure 300, the assembly gap between the roller brush cover plate 200 and the floor brush bottom shell 100 can be sealed, so that the first cavity 110 and the second cavity 120 are well isolated, ensuring the effect of sealing and preventing water leakage. And the floor brush housing 10 fixedly installs the roller brush cover plate 200 on the floor brush bottom shell 100 through the connection structure 400, so that the roller brush cover plate 200 and the floor brush bottom shell 100 are closely closed, making the sealing effect of the sealing structure 300 better.

[0053] Refer to Figure 1 , in the floor brush bottom shell 100 of this embodiment, a floor suction port 101 is provided, and the roller brush cover plate 200 is further provided with a sewage discharge port 201 for communicating with the sewage pipeline of the floor brush. The sewage discharge port 201 is communicated with the floor suction port 101 through the second cavity 120. The roller brush 20 is installed in the second cavity 120 and is located at the floor suction port 101. When the roller brush 20 rotates at a high speed, it can brush the bottom surface through the floor suction port 101. A water spraying seat 202 for spraying water on the roller brush 20 is further installed on the floor brush housing 10, which can spray water on the roller brush 20 when the roller brush 20 is brushing the floor, improving the cleaning ability. The space between the second cavity 120 and the sewage discharge port 201 constitutes the sewage suction channel of the floor brush. The sealing structure 300 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 outwards from the sewage suction channel, thereby avoiding the risk of sewage penetrating into the first cavity 110. The floor brush housing 10 may further include a floor brush upper shell 800, and the floor brush upper shell 800 is covered on the floor brush bottom shell 100, and a space for avoiding the water spraying seat 202 is reserved between the floor brush upper shell 800 and the roller brush cover plate 200. A waterproof sealing structure may be provided 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.

[0054] The structural form of the sealing structure 300 disposed between the roller brush cover plate 200 and the floor brush bottom shell 100 can be various. Refer to Figure 1 and Figure 3, As an implementable manner, the sealing structure 300 includes a sealing rabbet groove 310 and a sealing rabbet rib 320 that are engaged with each other. The sealing rabbet groove 310 is provided on one of the roller brush cover plate 200 and the floor brush bottom shell 100, and the sealing rabbet rib 320 is correspondingly provided on the other of the roller brush cover plate 200 and the floor brush bottom shell 100. As in Figure 1 the illustrated embodiment, the sealing rabbet groove 310 is provided on the roller brush cover plate 200, and the sealing rabbet rib 320 is correspondingly provided on the floor brush bottom shell 100 with respect to the sealing rabbet groove 310. Through the mutually engaged sealing rabbet groove 310 and sealing rabbet rib 320, the penetration of water can be effectively blocked, thereby achieving a good sealing and water-stopping effect.

[0055] See Figure 1 and Figure 3 , In one embodiment, the sealing rabbet groove 310 is a groove with a U-shaped cross-section. The U-shaped sealing rabbet groove 310 enables the sealing rabbet rib 320 to fit tightly with each other when it is engaged in the groove, and to a certain extent increases the travel of water penetration. Thereby further improving the sealing and water-stopping effect. Further, the sealing structure 300 further includes a sealing gasket 330, and the sealing gasket 330 is disposed in the sealing rabbet groove 310. The sealing gasket 330 can be made of materials such as silica gel and rubber. When the roller brush cover plate 200 and the floor brush bottom shell 100 are assembled, the sealing rabbet rib 320 is engaged in the sealing rabbet groove 310, and the sealing gasket 330 expands under the external pressing force, so as to better seal the assembly gap between the roller brush cover plate 200 and the floor brush bottom shell 100, and prevent the water in the second cavity 120 from leaking into the first cavity 110.

[0056] The structural form of the connection structure 400 can be various. See Figure 2 and Figure 4, as an implementable manner, the connection structure 400 includes a card slot 410 and a hook 420 respectively and correspondingly arranged on the roller brush cover plate 200 and the floor brush bottom shell 100. And / or, the connection structure 400 includes a screwing component 430 correspondingly arranged on the roller brush cover plate 200 and the floor brush bottom shell 100. It can be understood that the card slot 410 can be arranged on the roller brush cover plate 200, and the hook 420 is correspondingly arranged on the floor brush bottom shell 100 corresponding to the card slot 410. Or the card slot 410 is arranged on the floor brush bottom shell 100, and the hook 420 is correspondingly arranged on the roller brush cover plate 200 corresponding to the card slot 410. And the screwing component 430 correspondingly arranged on the roller brush cover plate 200 and the floor brush bottom shell 100 can include a threaded through-hole seat arranged on the roller brush cover plate 200 and a threaded fixing seat arranged on the floor brush bottom shell 100. A screw is passed through the threaded through-hole on the threaded through-hole seat, and the screw is tightly connected with the threaded fixing hole on the threaded fixing seat. Or, the screwing component 430 can also include 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 400 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.

[0057] The structural form of the lighting component 500 can be various. Refer to Figure 1 and Figure 3 , as an implementable manner, the lighting component 500 includes an LED light board. The floor brush bottom shell 100 is provided with a first clamping groove 111, and the LED light board is clamped in the first clamping groove 111. The roller brush cover plate 200 and the first clamping groove 111 form a first cavity 110. The LED light board can be a strip-shaped LED light board. The shape and size of the first clamping groove 111 can be adapted to the shape and size of the LED light board to better fix the LED light board. In other embodiments, the lighting component 500 can also include a lamp tube, and the lamp tube can be installed on the side wall of the first cavity 110.

[0058] It can be understood that after the LED light board is installed, the light-emitting area of the LED light board faces the front end of the floor brush housing 10 and transmits light outward. In one embodiment, the floor brush housing 10 further includes a light-transmitting sheet 130. A light-transmitting hole is opened on the side wall of the first clamping groove 111 opposite to the light-emitting area of the LED light board, and the light-transmitting sheet 130 is covered on the light-transmitting hole and seals the light-transmitting hole. Among them, the light-transmitting sheet 130 can be made into a structure with a transmissive texture to strengthen the divergence of light and make the lighting effect better. By setting the light-transmitting hole and the light-transmitting sheet 130, the lighting effect is improved. In other embodiments, the side wall of the first clamping groove 111 opposite to the light-emitting area of the LED light board can also be made of a transparent material, so that the light emitted by the LED light board can transmit outward.

[0059] Refer toFigure 1 and Figure 3 In one embodiment, the roller brush cover plate 200 is provided with a second clamping groove 210 corresponding to the first clamping groove 111. The first clamping groove 111 and the second clamping groove 210 form a first cavity 110. Both ends of the LED light board are respectively clamped in the first clamping groove 111 and the second clamping groove 210. The shape and size of the second clamping groove 210 can also be adapted to the shape and size of the LED light board. Through the first clamping groove 111 and the second clamping groove 210, the LED light board can be well fixed, ensuring the stable installation of the LED light board.

[0060] See Figure 1 and Figure 3 As an implementable manner, the floor brush housing 10 further includes a collision prevention portion 600 provided on the roller brush cover plate 200. When projected onto the supporting surface where the floor brush housing 10 is located, at least part of the collision prevention portion 600 is located outside the contour lines of the floor brush bottom shell 100 and the roller brush cover plate 200. That is to say, when the floor brush housing 10 is in use, if there are obstacles on the supporting surface, the collision prevention portion 600 can collide with the obstacles prior to the floor brush bottom shell 100 and the roller brush cover plate 200 on its inner side (i.e., the side of the collision prevention portion 600 close to the center of the housing body formed by the buckling of the floor brush bottom shell 100 and the roller brush cover plate 200), so as to prevent the floor brush bottom shell 100 and the roller brush cover plate 200 from being damaged.

[0061] The collision prevention portion 600 can be an anti-collision rubber strip provided at the front end of the roller brush cover plate 200. During specific production, the anti-collision rubber strip and the aforementioned sealing gasket 330 can be integrally injection-molded on the roller brush cover plate 200 directly. In this way, there is no need to assemble the anti-collision rubber strip and the sealing gasket 330, thereby reducing the assembly difficulty, improving the production efficiency, and the anti-collision rubber strip and the sealing gasket 330 are not easily separated from the roller brush cover plate 200, with good anti-collision effect and good sealing effect. See Figure 1 and Figure 5 During injection molding, since the sealing gasket 330 is located on the side of the roller brush cover plate 200 close to the floor brush bottom shell 100, and the anti-collision rubber strip is located on the outer side wall of the roller brush cover plate 200. Therefore, an injection molding through hole 203 can be opened on the roller brush cover plate 200 in the overlapping area of the sealing gasket 330 and the anti-collision rubber strip. When the anti-collision rubber strip and the sealing gasket 330 are injection-molded on the roller brush cover plate 200, the anti-collision rubber strip and the sealing gasket 330 are connected through the injection molding through hole 203, so that the anti-collision rubber strip and the sealing gasket 330 can be fixed more firmly to the roller brush cover plate 200.

[0062] See Figure 1, As an implementable manner, the floor brush housing 10 further includes a dust scraping strip assembly 700, which is disposed at the bottom of the floor brush bottom shell 100. The dust scraping strip assembly 700 includes a fixing portion 710 and a dust scraping strip 720. The dust scraping strip 720 is fixedly connected to the fixing portion 710. The fixing portion 710 is fixed to the floor brush bottom shell 100 through a fixing structure, and the dust scraping strip 720 is fixedly installed on the floor brush bottom shell 100 through the fixing portion 710. Compared with the dust scraping strip 720 in a traditional vacuum cleaner, which is usually installed and fixed on the floor brush housing 10 by a slot structure, there are problems such as unreliable installation and time-consuming and laborious installation of the dust scraping strip 720. In the embodiment of the present invention, the dust scraping strip 720 is fixedly installed on the floor brush bottom shell 100 through the fixing portion 710, and the installation is reliable and convenient for disassembly and assembly. It can be understood that the dust scraping strip 720 can be integrally injection molded with the fixing portion 710. Alternatively, the fixing portion 710 is provided with a slot for inserting the dust scraping strip 720, and the dust scraping strip 720 is inserted into the slot and fastened by using glue or the like.

[0063] The fixing portion 710 is fixed to the floor brush bottom shell 100 through a fixing structure. Among them, there can be various structural forms of the fixing structure. Refer to Figure 3 , In one embodiment, the fixing structure includes a first fixing hole 711, a second fixing hole 140, and a fixing member (not shown). The first fixing hole 711 is disposed on the fixing portion 710, the second fixing hole 140 is correspondingly disposed on the floor brush bottom shell 100 corresponding to the first fixing hole 711, and the fixing member passes through the first fixing hole 711 and is fixedly installed in the second fixing hole 140. The first fixing hole 711 can be a threaded through hole, the second fixing hole 140 can be a threaded hole, and the fixing member can be a screw. The screw passes through the first fixing hole 711 and is tightened and fixed in the second fixing hole 140, so as to realize the fixed installation of the fixing portion 710 and the floor brush bottom shell 100. Alternatively, the first fixing hole 711 and the second fixing hole 140 can both be through holes, the fixing member can be a bolt, and the bolt sequentially passes through the first fixing hole 711 and the second fixing hole 140 and a nut is sleeved on the bolt and tightened, so as to realize the fixed installation of the fixing portion 710 and the floor brush bottom shell 100.

[0064] Refer to Figure 1 , As an implementable manner, the floor brush housing 10 further includes a positioning structure, which is disposed between the fixing portion 710 and the floor brush bottom shell 100. The positioning structure includes a positioning rib 712 and a positioning slot (not shown). The positioning rib 712 is disposed on one of the fixing portion 710 and the floor brush bottom shell 100, and the positioning slot is correspondingly disposed on the other of the fixing portion 710 and the floor brush bottom shell 100 corresponding to the positioning rib 712. As Figure 1In the illustrated embodiment, the positioning rib 712 is provided on the fixing portion 710, and the positioning groove is provided on the floor brush bottom shell 100 corresponding to the positioning rib 712. Through the positioning rib 712 and the positioning groove, the position where the fixing portion 710 is assembled on the floor brush bottom shell 100 can be pre-positioned, so as to facilitate the subsequent fixed installation of the fixing portion 710 and the floor brush bottom shell 100, and effectively improve the assembly efficiency.

[0065] An embodiment of the present invention further provides a floor brush assembly, including the floor brush housing 10 described in any of the above solutions. Since the floor brush housing 10 has the above beneficial effects, the floor brush assembly including the floor brush housing 10 also has corresponding beneficial effects.

[0066] An embodiment of the present invention further provides a cleaning device, including the above floor brush assembly. The cleaning device can be a vacuum cleaner or a cleaning machine, etc.

[0067] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0068] The above-described embodiments only express several implementation manners of the present invention. The description is relatively specific and detailed, but it cannot be understood as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
