[0002] The floor brush is an important cleaning accessory of the surface cleaning device, and the cleaning efficiency can be improved by using the floor brush.

[0003] For surface cleaning devices such as vacuum cleaners and floor scrubbers, the floor brush generally includes a base that can move along the surface to be cleaned. The base is provided with a roller brush cavity, and a roller brush is installed in the roller brush cavity. The roller brush cavity is provided with a suction port, and the dirt driven by the roller brush is sucked away from the suction port. Therefore, in order to facilitate the cleaning of the roller brush cavity and the suction port, the roller brush needs to be removed. In the prior art, in order to further facilitate the user's operation, the top cover of the roller brush cavity can also be removed, so as to be more convenient for cleaning.

[0004] The top cover is also called a transparent window, which is a habitual name, but the top cover part is often black in order to prevent users from seeing the accumulation of dirt. However, the current structure requires the user to carefully align the operation, and the top cover is often black, resulting in more difficult alignment. Therefore, it is not user-friendly for the user to install the top cover. Therefore, how to facilitate the installation of the top cover needs further research. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide a floor brush that is beneficial to facilitate the installation of the top cover. For users, the structure after the improvement design is much easier to operate when installing the top cover; a surface cleaning device provided with the aforementioned floor brush is also provided.

[0006] Compared with the prior art, the utility model provides a floor brush, which includes a base that can move along the surface to be cleaned. The base is provided with a roller brush cavity, and a roller brush is installed in the roller brush cavity. The roller brush cavity is provided with a suction port, and the dirt driven by the roller brush is sucked away from the suction port. The roller brush cavity is provided with a top cover that can be disassembled and assembled. The base has a rear side surface at the rear of the roller brush in the roller brush cavity, and the rear side surface and the outer peripheral surface of the roller brush form a V-shaped guiding groove. The lower side of the top cover is provided with a V-shaped matching part, and the V-shaped matching part is in guiding cooperation with the V-shaped guiding groove. When the user covers the top cover back, the top cover is connected through the guiding cooperation of the V-shaped matching part and the V-shaped guiding groove, so that the top cover is automatically adjusted to the accurate position.

[0007] After adopting the above structure, compared with the prior art, the utility model has the following advantages:

[0008] Through improvement, the present disclosure uses a V-shaped guiding groove formed by the relative formation of the rear side surface and the outer peripheral surface of the roller brush for guiding, greatly reducing the burden of the user's alignment operation. As long as the user inserts it into the V-shaped guiding groove, under the guiding and mating connection of the V-shaped guiding groove and the V-shaped mating portion, the top cover will automatically adjust to the accurate position. Therefore, for the user, the structure after the improved design is much easier to operate when installing the top cover.

[0009] In some embodiments, there are two V-shaped mating portions, and these two V-shaped mating portions are sequentially distributed along the axial direction of the roller brush and are respectively arranged at both ends of the roller brush.

[0010] In some embodiments, a dirt shielding plate is provided at the rear side of the V-shaped mating portion. The dirt shielding plate connects the two V-shaped mating portions together, and the dirt shielding plate is used to block the transfer of dirt to the rear side.

[0011] In some embodiments, a plurality of reinforcing ribs are sequentially provided along the axial direction of the roller brush on the inner side of the dirt shielding plate.

[0012] In some embodiments, both of the two V-shaped mating portions are provided with docking grooves and / or docking holes arranged along the axial direction of the roller brush, and the base is provided with a telescopic portion. The telescopic portion is in docking fit with the docking groove and / or the docking hole to fix the V-shaped mating portion at least in the up and down directions, and further fix the top cover at least in the up and down directions.

[0013] In some embodiments, an unlocking button is further included. A transmission rod is provided between the unlocking button and the two telescopic portions. The unlocking button drives the telescopic portions to retract through the transmission rod to release the fixation of the top cover.

[0014] In some embodiments, the unlocking button is centrally arranged. There are two transmission rods which are respectively located on both sides of the unlocking button. The telescopic portion is integrally provided with the transmission rod. The transmission rod is connected with a spring. When the unlocking button is pressed, the transmission rod is pushed to move towards both sides through the inclined surface fit between the unlocking button and the end of the transmission rod, thereby driving the telescopic portions to retract. When the unlocking button is released, the unlocking button rebounds, and at the same time, under the action of the spring, the transmission rod resets, driving the telescopic portions to relatively extend; based on the setting of the spring, when the user covers the top cover back, pressing it down once can make the telescopic portions retract so that the top cover is plugged in place, and at the same time, the telescopic portions extend under the action of the spring and are inserted into the docking groove.

[0015] In some embodiments, the rear side surface is arranged as a vertical surface along the up and down direction.

[0016] In some embodiments, a plurality of water spraying holes are sequentially provided along the axial direction of the roller brush below the rear side surface.

The embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles defined in the following description can be applied to other embodiments, variations, improvements, equivalent solutions, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0030] Those skilled in the art should understand that in the disclosure of this utility model, the orientation or positional relationships indicated by the terms "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings. These are only for the convenience of describing this utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0031] As Figures 1 to 9 shown, there is a floor brush, which includes a base 1 that can move along the surface to be cleaned. The base 1 is provided with a roller brush cavity. A roller brush 2 is installed in the roller brush cavity. The roller brush cavity is provided with a suction port 3. The dirt driven by the roller brush 2 is sucked away from the suction port 3. The roller brush cavity is provided with a top cover 4, and the top cover 4 can be disassembled and assembled. The base 1 has a rear side surface 5 at the rear of the roller brush 2 in the roller brush cavity. The rear side surface 5 and the outer peripheral surface of the roller brush 2 form a V-shaped guiding groove relatively. The lower side of the top cover 4 is provided with a V-shaped mating part 6, and the V-shaped mating part 6 is in guiding cooperation with the V-shaped guiding groove. The base 1 is provided with a plug hole 7 at the rear part of the rear side surface 5. The lower side of the top cover 4 is provided with a plug part 8. When the top cover 4 is connected through guiding cooperation of the V-shaped mating part 6 and the V-shaped guiding groove, the plug part 8 is inserted into the plug hole 7 from top to bottom under the guidance of the above-mentioned guiding connection to realize front-rear limit. By reverse operation, the top cover 4 can be removed from bottom to top.

[0032] When the top cover 4 is connected through guiding cooperation of the V-shaped mating part 6 and the V-shaped guiding groove, further, the plug part 8 is inserted into the plug hole 7 from top to bottom under the guidance of the above-mentioned guiding connection to realize front-rear limit, so as to achieve a certain installation purpose. By reverse operation, the top cover 4 can be removed from bottom to top, that is, the user lifts the top cover 4 upward to remove the top cover 4 from bottom to top.

[0033] As Figure 7 、 9 shown, the roller brush cavity is essentially a downward-opening notch provided at the front end of the base 1. The roller brush 2 is installed in this notch, and the roller brush 2 contacts the surface to be cleaned through this downward opening. In order to be able to clean the front, as Figure 7 shown, so the front side of the notch is also an open design.

[0034] The shape of the V-shaped guiding groove determines the shape of the V-shaped mating part 6. In this example, the V-shaped mating part 6 includes an arc surface at the front side and a side surface at the rear side.

[0035] In some embodiments, as Figure 5 、 7As shown, the rear side surface 5 is arranged in a vertical surface along the up-down direction. In this way, the shape of the front and rear side surfaces 5 of the V-shaped guide groove is formed such that the front side is the outer peripheral surface of the roller brush 2 and the rear side is the vertical surface, and the shape of the V-shaped matching portion 6 is adapted to Figure 4 The above-mentioned design is more conducive to the success rate of the top cover 4 installation, and the vertical surface provides better support, so that the top cover 4 is more stable when subjected to force.

[0036] like Figure 4 As shown, in order to make the plug-in portion 8 more smoothly inserted into the plug-in hole 7 from top to bottom under the guidance of the aforementioned guide fitting connection, the plug-in portion 8 is configured to be a V-shaped structure that is adapted to the guide fitting direction of the V-shaped fitting portion 6 and the V-shaped guide groove. The shapes of the front and rear side surfaces of the V-shaped structure can be finally determined based on a limited number of experiments. The experimental method, for example, designs plug-in portions 8 of different shapes, and then determines which one is more suitable through actual plug-in. It will not be described in detail here.

[0037] In order to further improve the success rate of the top cover 4 installation, Figure 4 As shown, the top of the top cover 4 is inclined upward from front to back, the V-shaped matching portion 6 and the plug-in portion 8 are arranged in sequence from front to back, and the lower end of the plug-in portion 8 is higher than the lower end of the V-shaped matching portion 6.

[0038] In some embodiments, Figure 2 As shown, the V-shaped matching parts 6 include two, and the two V-shaped matching parts 6 are sequentially distributed along the axial direction of the roller brush 2 and are respectively arranged at two ends of the roller brush 2. This has better guiding performance.

[0039] In some embodiments, Figure 2 As shown, a dirt shielding plate 9 is provided at the rear side of the V-shaped matching portion 6, and the dirt shielding plate 9 connects the two V-shaped matching portions 6 together, and the dirt shielding plate 9 is used to block dirt from transferring to the rear side. In this way, dirt is effectively blocked from transferring to the rear side, reducing the difficulty of cleaning.

[0040] Furthermore, the dirt baffle 9 connects the two V-shaped matching parts 6 together to form a frame-shaped stable structure, which has better strength and is used to withstand the force applied by the roller brush 2 when it is working.

[0041] Further, such as Figure 2 As shown, a plurality of reinforcing ribs 10 are sequentially arranged on the inner side of the dirt baffle plate 9 along the axial direction of the roller brush 2 .

[0042] In some embodiments, Figure 2 , 7As shown in FIGS. 8, each of the two V-shaped mating portions 6 is provided with a docking groove 11 and / or a docking hole arranged along the axial direction of the roller brush 2. The base 1 is provided with a telescopic portion 12, and the telescopic portion 12 is in docking fit with the docking groove 11 and / or the docking hole to fix the V-shaped mating portion 6 at least in the up and down directions, thereby fixing the top cover 4 at least in the up and down directions. This can better fix the top cover 4.

[0043] In this example, it is preferably set as the docking groove 11 to prevent dirt from entering the side of the telescopic portion 12 through the docking hole.

[0044] In some embodiments, such as Figure 5 , 8 shown, it further includes an unlocking button 13. A transmission rod 14 is provided between the unlocking button 13 and the two telescopic portions 12. The unlocking button 13 drives the telescopic portions 12 to retract through the transmission rod 14 to release the fixation of the top cover 4.

[0045] The unlocking button 13 is centrally arranged. There are two transmission rods 14 which are respectively located on both sides of the unlocking button 13. The telescopic portion 12 is integrally provided with the transmission rod 14. The working principle can be referred to as follows. When the unlocking button 13 is pressed, it pushes the transmission rod 14 to move to both sides through the cooperation with the inclined surface at the end of the transmission rod 14, thereby driving the telescopic portion 12 to retract. When the unlocking button 13 is released, the unlocking button 13 rebounds. At the same time, under the action of the spring 16, the transmission rod 14 resets and drives the telescopic portion 12 to protrude relatively. Due to the setting of the spring 16, when the user covers the top cover 4 back, pressing it down once can make the telescopic portion 12 retract so that the top cover 4 is inserted in place. At the same time, the telescopic portion 12 protrudes under the action of the spring 16 and inserts into the docking groove 11.

[0046] In some embodiments, such as Figure 9 shown, a plurality of water spraying holes 15 are sequentially arranged along the axial direction of the roller brush 2 below the rear side surface 5. In this way, the function of the water spraying holes 15 is to moisten the roller brush 2. Then in the present disclosure, it is more reasonable to set them below the rear side surface 5, which is beneficial to simplifying the design of the top cover 4. The top cover 4 does not need to be provided with corresponding structures for considering the setting of the water spraying holes 15.

[0047] Furthermore, the top of the top cover 4 is inclined upward obliquely from front to back, the V-shaped engaging portion 6 and the plugging portion 8 are arranged in sequence obliquely upward from front to back, and the lower end of the plugging portion 8 is higher than the lower end of the V-shaped engaging portion 6. There are two V-shaped engaging portions 6, and these two V-shaped engaging portions 6 are sequentially distributed along the axial direction of the rolling brush 2 and are respectively arranged at both ends of the rolling brush 2. A dirt blocking plate 9 is arranged at the rear side of the V-shaped engaging portion 6. The dirt blocking plate 9 connects the two V-shaped engaging portions 6 together to form a frame-shaped stable structure. The dirt blocking plate 9 is attached to the rear side surface 5, and the lower end of the dirt blocking plate 9 is higher than each water spraying hole 15. In this way, the top of the top cover 4 being inclined upward obliquely from front to back leaves a height space for arranging the water spraying holes 15, and at the same time, it also increases the success probability of installing the top cover 4. In addition, the overall height of the floor brush is controlled within a relatively reasonable range.

[0048] The present disclosure also provides a surface cleaning device, including the floor brush of any one of the foregoing technical solutions.

[0049] The surface cleaning device is, for example, a vacuum cleaner, a floor washer, etc.

[0050] When understanding the present disclosure, if necessary, the above structure can refer to other embodiments / appendices Figure 1 and it is understood that no further elaboration will be made here.

[0051] The above are only the exemplary embodiments for illustration of the present utility model. Therefore, any equivalent changes or modifications made according to the structures, features and principles described in the protection scope of the present utility model patent are included in the protection scope of the present utility model patent.
