[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 , Figure 2 , Figure 3as well as Figure 4 This utility model provides a technical solution: a drum structure for a floor scrubber, including a machine head 1, a drum body 11 inside the machine head 1, a side cleaning component on the drum body 11, and a combing component on the machine head 1. The side cleaning component includes a bracket 21 connected to both sides of the machine head 1, a rotating shaft 22 fixedly connected to both sides of the drum body 11, a threaded portion 23 on both sides of the rotating shaft 22, a threaded cylinder 24 connected to the threaded portion 23, side brushes 25 fixedly connected to the threaded cylinder 24, and a drive component for rotating the drum body 11. The threaded portion 23 is screwed into the threaded cylinder 24, and the rotating shaft 22 is rotatably connected to the bracket 21. The threaded portion 23 can be screwed into the threaded cylinder 24, thereby quickly cleaning the two side brushes 25 against the drum body 11. The roller body 11 is fixed in place, and its rotation can drive the two side brushes 25 to rotate, enabling edge cleaning, thereby increasing the cleaning range and reducing cleaning dead corners. At the same time, the side brushes 25 can be quickly replaced and maintained. The driving components include a second motor 41 fixedly connected to one side of the inner wall of the head 1, a drive shaft 42 fixedly connected to the output end of the second motor 41, and a friction roller 43 fixedly connected to the outside of the drive shaft 42. The friction roller 43 contacts the roller body 11, and the rotating shaft 22 is rotatably connected to the inner wall of the head 1. When the second motor 41 is started, it can drive the drive shaft 42 to rotate, which in turn causes the friction roller 43 to rotate. The rotation of the friction roller 43 can drive the roller body 11 to rotate using friction, providing power for the rotation of the roller body 11.

[0026] Please see Figure 1 , Figure 2 , Figure 5 as well as Figure 6The combing components include an opening 31 at the top of the comb head 1, a fixing frame 32 fixedly connected to the top of the comb head 1, a first motor 33 fixedly connected to the top of the fixing frame 32, a screw 34 fixedly connected to the bottom of the first motor 33, a drive frame 35 connected to the outside of the screw 34, a mounting base 36 fixedly connected to the bottom of the drive frame 35, and a cleaning nozzle 37 connected to the bottom of the mounting base 36. The screw 34 is screwed to the drive frame 35 and rotatably connected to the fixing frame 32. The first motor 33 can drive the screw 34 to rotate, and the screw 34 can cause the drive frame 35 to rotate. The vertical movement of the frame 35, in turn, causes the mounting base 36 and the cleaning auger 37 to move vertically, allowing the cleaning auger 37 to contact the roller body 11 and scrape off the hair on the roller body 11, enabling quick cleaning of the roller body 11. The fixed frame 32 has anti-rotation grooves 51 on both sides, with anti-rotation blocks 52 slidably connected within the anti-rotation grooves 51. A connecting plate 53 is fixedly connected between the anti-rotation blocks 52 and the drive frame 35. The drive frame 35 can drive the connecting plate 53 and the anti-rotation blocks 52 to move vertically synchronously. The anti-rotation blocks 52 prevent the drive frame 35 from moving vertically. Rotating synchronously with the screw 34, the mounting base 36 has a connecting groove 61 at its bottom. A plate 62 is fixedly connected to the top of the cleaning ditch 37. A locking groove 63 is formed on one side of the plate 62. A through-hole 64 is formed on one side of the inner wall of the connecting groove 61. A locking rod 65 is slidably connected within the through-hole 64. A movable ring 66 is fixedly connected to the outside of the locking rod 65. A spring 67 is fixedly connected to one side of the movable ring 66. The locking rod 65 is inserted into the locking groove 63. Pulling the locking rod 65 moves the movable ring 66, causing the spring 67 to deform, allowing the plate 62 to be inserted into the connecting groove 61. The spring 67 resets, which can drive the locking rod 65 into the locking groove 63, quickly fixing the cleaning sprue 37 and allowing for quick disassembly and replacement of the cleaning sprue 37. The bottom of the screw 34 is provided with an anti-detachment plate 71, which is fixedly connected to the screw 34. The anti-detachment plate 71 can limit the vertical movement distance of the drive frame 35 and prevent the drive frame 35 from detaching from the screw 34. The anti-rotation block 52 is T-shaped, and the anti-rotation groove 51 is T-shaped, which can limit the anti-rotation block 52 and prevent the anti-rotation block 52 from moving laterally and detaching from the anti-rotation groove 51.

[0027] Working principle: During operation, align the threaded cylinder 24 with the threaded part 23, then rotate the side brush 25 so that the threaded part 23 is screwed into the threaded cylinder 24, thereby quickly connecting and fixing the side brush 25 to the roller body 11. Pulling the locking rod 65 can move the moving ring 66, which in turn causes the spring 67 to deform, allowing the insert plate 62 to be inserted into the connecting groove 61. The spring 67 returns to its original position, causing the locking rod 65 to engage in the locking groove 63, thus quickly fixing the cleaning slurry 37. Then, start the first motor 33, which drives the screw 34 to rotate. The rotation of the screw 34 causes the drive frame 35 to move downward, which in turn causes the mounting base 36 and the cleaning slurry 37 to move downward, allowing the cleaning slurry 37 to engage with the roller body. When the first motor 33 is in contact with the machine head 1, the second motor 41 is started, which drives the drive shaft 42 to rotate. The drive shaft 42 drives the friction roller 43 to rotate, which in turn drives the roller body 11 to rotate, thus cleaning the ground. The roller body 11 drives the side brush 25 to rotate, which can clean the edges. As the roller body 11 rotates, the cleaning sprue 37 can clean the hair on the roller body 11, leaving the hair on the cleaning sprue 37. When not in use, the first motor 33 reverses, causing the cleaning sprue 37 to move upward and move out of the machine head 1, and then the hair on the cleaning sprue 37 can be cleaned off. The above is the working process of the entire device. All contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
