[0046] The present invention provides a roller brush cover 100, which can be applied to a roller brush mechanism 1000 of a cleaning device. The roller brush cover 100 covers the roller brush 200, so that negative pressure can be formed around the roller brush 200, which is conducive to the roller brush 200 rolling up the dirt on the surface to be cleaned and sucking the dirt into the cleaning device for storage. Figures 1 to 3 In this embodiment, the roller brush cover 100 includes a main cover body 1 and an isolating member 2. The main cover body 1 is formed with a accommodating cavity 11. At least the bottom area of ​​the accommodating cavity 11 is open. The accommodating cavity 11 is suitable for accommodating the roller brush 200 and has a cleaning surface suitable for surrounding the roller brush 200. The isolating member 2 is detachably arranged in the accommodating cavity 11 and is suitable for isolating the cleaning surface and the roller brush 200.

[0047] In this embodiment, a receiving chamber 11 is formed on the main cover 1, and at least a region at the bottom of the receiving chamber 11 is open, so that the roller brush 200 can be accommodated in the receiving chamber 11 and can extend from the open region at the bottom of the receiving chamber 11 to better contact the surface to be cleaned and clean the surface to be cleaned. In addition, an isolating member 2 is also provided in the receiving chamber 11 of the main cover 1. The isolating member 2 can isolate the cleaning surface on the main cover 1 from the roller brush 200, so that dirt rolled up by the roller brush 200 during the cleaning process of the cleaning device will not adhere to the main cover 1, but will adhere to the isolating member 2. Since the isolating member 2 is detachably provided on the main cover 1, after the cleaning device has been operating for a certain period of time, the isolating member 2 can be removed from the main cover 1 for cleaning, making the cleaning operation simpler and more convenient, thereby facilitating the maintenance of the cleanliness of the cleaning device and extending the service life of the cleaning device.

[0048] The shape of the accommodating cavity 11 is adapted to the shape of the roller brush 200 so as to cover the outer peripheral side of the roller brush 200 and form a certain gap between the accommodating cavity 11 and the roller brush 200. Figure 4 As shown in , the cleaning device may include a device body and a roller brush mechanism 1000 provided on the device body. The roller brush mechanism 1000 includes the roller brush cover 100 and the roller brush 200. When the cleaning device is operating normally, the forward direction of the cleaning device is the front side of the device body, and the backward direction of the cleaning device is the rear side of the device body. The axial direction of the roller brush 200 is arranged along the left and right direction of the device body. The accommodating cavity 11 is arranged in an elongated strip shape to have a long side and a short side. The long side of the accommodating cavity 11 is arranged along the left and right direction of the device body, and the short side of the accommodating cavity 11 is arranged along the front and back direction of the device body, so as to facilitate the installation of the roller brush 200 therein. Unless otherwise specified, the description of the orientation in this utility model is based on this.

[0049] Specifically, combined Figure 2 and Figure 3As shown, the accommodating chamber 11 has a first bottom wall arranged in an arc shape, and two first side walls located at both ends of the first bottom wall along the axial direction thereof. The first bottom wall is roughly semicircular in shape and has a flat bottom. A roughly circular first mounting hole is provided on one of the first side walls, and a limiting groove 12 is provided on the other first side wall. One end of the roller brush 200 is installed in the first mounting hole, and the other end of the roller brush 200 is installed in the limiting groove 12. Of course, a suction device, such as a fan or an air pump, can also be provided in the cleaning device. A dust suction port connected to the accommodating chamber 11 is provided on one side of the first bottom wall. A soft rubber channel is connected to the outside of the dust suction port, which can be connected to the suction device through the soft rubber channel, so that the dirt rolled up by the roller brush 200 can be sucked into the soft rubber channel from the dust suction port to be stored in the dirt storage chamber in the cleaning device.

[0050] The isolating member 2 is located in the accommodating cavity 11 , and the shape of the isolating member 2 is adapted to the shape of the accommodating cavity 11 , so that the isolating member 2 can better fit the main cover 1 , occupying less space and reducing the impact on the activity space of the roller brush 200 .

[0051] Among them, the isolating member 2 has a second bottom wall arranged in contact with the first bottom wall, and two second side walls located at both ends of the second bottom wall along the axial direction of the accommodating cavity 11, the second bottom wall is also roughly semicircular, and the bottom is at least partially overlapped with the bottom of the first bottom wall, and the two second side walls are respectively arranged in contact with the two first side walls, so that each surface of the accommodating cavity 11 facing the roller brush 200 can be isolated by the isolating member 2, which better prevents dirt from falling on the main cover body 1 and ensures the cleanliness of the main cover body 1.

[0052] The second bottom wall is provided with a through hole corresponding to the dust suction port, and a flange is protruding from the second bottom wall. The flange is arranged around the side of the through hole and at least partially extends into the dust suction port, so that the isolation member 2 is better adapted to the main cover body 1 and dirt can be prevented from entering the gap between the second bottom wall and the dust suction port.

[0053] It is understood that there are many ways to detachably connect the spacer 2 to the main cover 1. For example, the spacer 2 and the main cover 1 can be fixed together using screws, bolts, etc.; or, the spacer 2 and the main cover 1 can be connected by an interference fit; or, the spacer 2 and the main cover 1 can be connected by a magnetic structure, etc., so that the spacer 2 can be easily disassembled and assembled and all such arrangements are within the scope of protection of this application.

[0054] Preferably, combined Figure 2 and Figure 3As shown, the isolator 2 has a first side and a second side that are arranged opposite each other. The first side of the isolator 2 is provided with a positioning portion 21, and the second side of the isolator 2 is provided with a snap-fit ​​portion 22. The main cover 1 is provided with a first mating portion 14 that is positioned and matched with the positioning portion 21, and a second mating portion 15 that is snap-fitted with the snap-fit ​​portion 22. After the positioning portion 21 is positioned and matched with the first mating portion 14, the isolator 2 is rotated at a certain angle to drive the snap-fit ​​portion 22 to snap-fit ​​with the second mating portion 15, thereby fixing the isolator 2 to the main cover 1. The isolator 2 is initially positioned on the main cover 1 by the positioning portion 21 and the first mating portion 14, and then the snap-fit ​​portion 22 and the second mating portion 15 are snap-fitted and locked, thereby completely fixing the isolator 2 to the main cover 1. When assembling the isolating member 2 and the main cover 1, accurate alignment can be ensured first to ensure the isolation effect of the isolating member 2, and then the isolating member 2 can be more reliably fixed to the main cover 1. Compared with the above-mentioned screw connection method, no disassembly tools are required when disassembling the isolating member 2, which is more convenient to operate and can ensure that the isolating member 2 is more secure and not easy to fall off during the operation of the cleaning device.

[0055] Further preferably, the first side and the second side of the isolating member 2 are both arranged along the long sides of the accommodating cavity 11; the positioning portion 21 includes a plurality of first positioning protrusions 211 provided on the first side of the isolating member 2, and the plurality of first positioning protrusions 211 protrude from the outside of the second bottom wall of the isolating member 2, and the plurality of first positioning protrusions 211 are evenly spaced apart along the left-right direction. It should be noted that the outside and the inside here are relative to the accommodating cavity 11, the center of the accommodating cavity 11 is the inside, and the outer surface of the accommodating cavity 11 is the outside. The snap-fitting portion 22 includes a plurality of hooks 221 provided on the second side of the isolating member 2, and the plurality of hooks 221 are spaced apart along the left-right direction to form the bottom of the second bottom wall of the isolating member 2. The first mating portion 14 includes a plurality of first positioning holes 141 provided on one of the long sides of the accommodating cavity 11. The plurality of first positioning holes 141 are provided in a one-to-one correspondence with the plurality of first positioning protrusions 211. The second mating portion 15 includes a plurality of latching grooves 151 provided on the other long side of the accommodating cavity 11. The plurality of latching hooks 221 are engaged with the plurality of latching grooves 151 in a one-to-one correspondence. Since the long sides of the accommodating cavity 11 are relatively long, the connection between the isolating member 2 and the main cover 1 is arranged on the long sides, so that there are more connection points on the long sides, and the connection between the isolating member 2 and the main cover 1 can be more reliable.

[0056] Preferably, combined Figure 1 and Figure 2As shown, there are two hooks 221, which are located at the left and right ends of the bottom of the second bottom wall. Each hook 221 is an elastic hook 221. The bottom of the first bottom wall is provided with a flange facing outward. The flange corresponds to the groove 151 and is provided with a relief groove. The bottom of the elastic hook 221 overlaps the relief groove, and the hook portion of the hook 221 is locked in the groove 151. When removing the isolator 2, you can reach into the relief groove to pull the ends of the two hooks 221, thereby quickly unlocking the isolator 2 and the main cover 1. When installing, after the multiple first positioning protrusions 211 are engaged with the multiple first positioning holes 141, press the isolator 2 in the direction close to the accommodating cavity 11, so that the multiple hooks 221 can be correspondingly locked in the multiple grooves 151, so as to quickly install the isolator 2, making the disassembly and assembly of the isolator 2 more convenient and labor-saving.

[0057] Moreover, when at least part of the bottom of the isolating member 2 overlaps at least part of the bottom of the main cover 1, the bottom of the isolating member 2 must be kept flush with the bottom of the main cover 1, so that the isolating member 2 can form a shield for the main cover 1, which can better prevent stains from entering the main cover 1 through the gap at the bottom.

[0058] In addition, two rotating shafts are protruding from the side of the main cover body 1 facing away from the accommodating cavity 11. The two rotating shafts are arranged in parallel on the outer side of the first bottom wall and are suitable for being rotatably connected with the cleaning body, so that during the cleaning process of the roller brush 200, the rotation of the rotating shaft can drive the entire roller brush cover 100 and the roller brush 200 to rise and fall together, so that the cleaning equipment can better adapt to the cleaning needs of uneven surfaces during the cleaning process, and the cleaning effect is better.

[0059] The utility model also provides a roller brush mechanism 1000, combined with Figures 4 to 6 As shown, the roller brush mechanism 1000 includes the above-mentioned roller brush cover 100, roller brush 200 and bottom cover structure 300, the roller brush 200 is rotatably arranged in the accommodating cavity 11 of the roller brush cover 100, and the isolation member 2 of the roller brush cover 100 is arranged around the outer peripheral side of the roller brush 200; the detachable cover of the bottom cover structure 300 is arranged on the open side of the accommodating cavity 11, and at least part of the roller brush 200 can be exposed from the bottom of the bottom cover structure 300. On the one hand, the bottom of the roller brush cover 100 can be sealed by the bottom cover structure 300 to better prevent dirt from entering the gap between the cover body and the isolation member 2 from the bottom. On the other hand, negative pressure can be better formed around the roller brush 200, so that after dirt enters the accommodating cavity 11 from the bottom cover structure 300, it can better enter the dust suction port.

[0060] Furthermore, the bottom cover structure 300 is detachable, which allows for better cleaning of the roller brush mechanism 1000. When the roller brush mechanism 1000 stops working, the bottom cover structure 300 can be removed first, followed by the roller brush 200, and finally the isolation member 2. This allows all parts of the roller brush mechanism 1000 that come into contact with dirt to be removed for cleaning and maintenance, thereby better ensuring the cleanliness of the roller brush mechanism 1000 and extending its service life.

[0061] It can be understood that the bottom cover structure 300 can be connected to the main cover body 1 and / or can be connected to the isolation member 2. Figure 5 and Figure 6 As shown, the bottom cover structure 300 includes a bottom cover body 41 and a locking structure 42. The shape of the bottom cover body 41 matches the shape of the cover body. The bottom cover body 41 is located on the open side of the accommodating cavity 11 and is provided with a through hole. The roller brush 200 can be exposed through the through hole, so that at least a portion of the roller brush 200 can extend from the through hole to contact the surface to be cleaned. The locking structure 42 is movably arranged on the bottom cover body 41 and has a locked state in which it is locked with the main cover body 1 and an unlocked state in which it is unlocked from the main cover body 1. When the roller brush mechanism 1000 is operating normally, the locking structure 42 is in the locked state to ensure that the roller brush 200 can better perform the cleaning work. When the roller brush mechanism 1000 completes the cleaning work, the locking structure 42 can be driven into the unlocked state, so that the bottom cover structure 300 can be removed from the cover body, thereby facilitating the removal of the roller brush 200 and the isolation member 2.

[0062] Further, if Figure 5 As shown in , a mounting groove 412 is formed on the bottom cover body 41. Preferably, the mounting groove 412 is located at the bottom of the bottom cover body 41, and the groove is set downward, so that the locking structure 42 can be better exposed to the outside of the roller brush mechanism 1000, which is convenient for users to operate. Figure 6 and Figure 7As shown, the locking structure 42 includes a locking block 421 movably disposed in the mounting groove 412, and an elastic member 422 connecting the locking block 421 and the mounting groove 412. A locking hole 13 is provided on the main cover body 1. When the locking block 421 is moved from the locked state to the unlocked state by an external force, the elastic member 422 is in an elastic energy storage state, and the locking block 421 moves in a direction to disengage from the locking hole 13. When the locking block 421 is completely disengaged from the locking hole 13, the bottom cover structure 300 can be removed from the cover body. When the external force applied to the locking block 421 is removed, the locking block 421 moves toward the locking hole 13 under the elastic restoring force of the elastic member 422, so that at least a portion of the locking block 421 can extend into the locking hole 13 to lock with the locking hole 13, thereby fixing the bottom cover structure 300 to the cover body. The installation of the bottom cover structure 300 is more labor-saving and easy to operate. The elastic member 422 can be configured as a telescopic spring or an elastic rubber member.

[0063] In which, the locking structure 42 can be arranged near a long side of the bottom cover body 41, a second positioning portion 21 is provided on the bottom cover body 41, and a third matching portion 16 is provided on the cover body. Specifically, the second positioning portion 21 includes a plurality of second positioning protrusions 413 provided on the bottom cover body 41, and the third matching portion 16 includes a plurality of second positioning holes 161 provided on the cover body. The plurality of second positioning protrusions 413 and the plurality of second positioning holes 161 are positioned and matched in a one-to-one correspondence, and the plurality of second positioning holes 161 and the plurality of first positioning holes 141 are located on the same side of the main cover body 1 and are staggered in the length direction. Moreover, a plurality of clearance holes are provided on the isolation member 2, and the plurality of second positioning protrusions 413 can be passed through the plurality of clearance holes in a one-to-one correspondence to extend into the corresponding plurality of second positioning holes 161. At the same time, the position of the isolation member 2 can be further restricted to ensure that the isolation member 2 is more stable during operation.

[0064] More preferably, Figure 6 As shown in the figure, there are two locking structures 42, and the locking blocks 421 of the two locking structures 42 are arranged to move relative to each other. The two locking structures 42 are spaced apart along the left and right directions of the bottom cover body 41. The locking blocks 421 of the two locking structures 42 can simultaneously move toward the center and move away from each other. When unlocking, the user can press both locking blocks 421 with one hand to unlock the bottom cover structure 300, making it easier to remove the bottom cover structure 300.

[0065] Among them, combined Figure 4 and Figure 5As shown, a limiting groove 12 is provided at one end of the main cover body 1, and a notch is provided at the bottom of the limiting groove 12; the roller brush 200 includes a roller brush body 31, a first mounting head 32 and a second mounting head 33, and the roller brush body 31 is arranged in the accommodating cavity 11; the first mounting head 32 is arranged at one axial end of the roller brush body 31, and is rotatably arranged at the first mounting hole, and the first mounting head 32 is suitable for being driven and connected with a driving mechanism, and the first mounting head 32 is driven to rotate by the driving mechanism, thereby driving the roller brush body 31 to rotate together.

[0066] The second mounting head 33 is rotatably mounted at the other axial end of the roller brush body 31 and is engaged within the retaining groove 12. A rotationally fixed engagement is formed between the second mounting head 33 and the retaining groove 12. The second mounting head 33 secures the other side of the roller brush body 31 to the main cover 1, allowing the roller brush body 31 to rotate relative to the second mounting head 33. A crimping portion 411 is provided on the bottom cover body 41. The crimping portion 411 extends from the notch into the retaining groove 12 to crimp the second mounting head 33 within the retaining groove 12. The rotationally fixed engagement between the retaining groove 12 and the second mounting head 33 circumferentially limits the second mounting head 33. Furthermore, the crimping portion 411 crimps the second mounting head 33, axially limiting its position and ensuring that the second mounting head 33 is completely secured within the retaining groove 12, thus ensuring secure installation of the roller brush 200. After the bottom cover structure 300 is disassembled, the second mounting head 33 can be drawn out from the limiting groove 12 , making the assembly and disassembly of the roller brush 200 more convenient.
