Taking a cleaning machine as an example, the cleaning machine includes a floor brush, and the end of the floor brush is equipped with a roller brush. The roller brush directly contacts the floor. During the cleaning process, too much dirt will accumulate on the surface, so it needs to be replaced or cleaned after a period of use.

[0003] As a consumable part, the roller brush needs frequent replacement. However, since the roller brush is mounted on the chassis of the cleaning device, it needs to be removed and installed between the chassis and the ground when replacing it. Considering the small gap between the chassis and the ground, the space for replacing the roller brush is limited, resulting in difficult removal and installation, poor visibility, and a cumbersome process. Alternatively, the existing roller brush assembly connection method may be complex and inconvenient to operate. This reduces cleaning efficiency, provides a poor user experience, and necessitates improvement.

[0004] Therefore, reducing the difficulty of disassembling the roller brush and simplifying the disassembly and assembly process are urgent technical problems that need to be solved. Utility Model Content

Only a disassembly force is applied to the second end, compressing the elastic element. The roller brush then moves from the second end to the first end, rapidly separating from the inner wall of the connected housing. At the moment of separation, the elastic element tends to return to its initial state, providing a reaction force to the roller brush, causing the second end to quickly eject from the roller brush cavity. This enables rapid disassembly of the roller brush, improving the maintainability of the cleaning device. The roller brush of this cleaning device is simple to install and operate, highly stable, and easy to disassemble for replacement or repair, making it convenient to use and providing a superior user experience.

[0038] As can be seen from the background technology, the roller brush structure of existing cleaning devices still needs improvement.

[0039] The inventors discovered that a roller brush is assembled inside a roller brush cavity. The roller brush includes a first end and a second end, which are detachably connected to the inner wall of the housing. An elastic element is provided between the first end and the inner wall of the housing. The elastic element causes the roller brush to tend to move from the second end to the first end. During the disassembly or replacement of the roller brush, only a disassembly force needs to be applied to the second end to compress the elastic element. At this time, the roller brush moves from the second end to the first end, and the second end quickly separates from the connected inner wall of the housing. At the moment of separation, the elastic element tends to return to its initial state, which gives the roller brush a reaction force, causing the second end to quickly pop out of the roller brush cavity. This allows the roller brush to be disassembled. The structure is simple, improves the convenience of roller brush disassembly and assembly, and is highly efficient. It enables rapid disassembly and installation of the roller brush, which is beneficial for improving cleaning efficiency during operation and rapid daily maintenance of the roller brush.

[0040] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0041] First, please refer to the reference. Figures 1 to 9 A cleaning device 100 includes a roller brush structure 101.

[0042] In this embodiment, the roller brush structure 101 includes a roller brush portion 102, the roller brush portion 102 including a roller brush cavity 104 surrounded by a housing 103; a roller brush 105 is assembled in the roller brush cavity 104, the roller brush 105 includes a first end 105a and a second end 105b opposite to each other, the first end 105a and the second end 105b are respectively detachably connected to the inner wall of the housing 103, and an elastic member 106 is provided between the first end 105a and the inner wall of the housing 103, the elastic member 106 causing the roller brush 105 to have a tendency to move from the second end 105b to the first end 105a.

[0043] In this embodiment, an elastic element 106 is provided between the first end 105a and the inner wall of the housing 103. The elastic element 106 causes the roller brush 105 to tend to move from the second end 105b to the first end 105a. During the disassembly or replacement of the roller brush 105, only a disassembly force needs to be applied to the second end 105b to compress the elastic element 106. At this time, the roller brush 105 moves from the second end 105b to the first end 105a, and the second end 105b quickly separates from the inner wall of the connected housing 103. At the moment of separation, the elastic element 106 tends to return to its initial state, and a reaction force is applied to the roller brush 105, causing the second end 105b to quickly pop out from the roller brush cavity 104. In this way, the roller brush 105 can be disassembled. Its structure is simple, improves the convenience of disassembly and assembly of the roller brush 105, and is highly efficient. It realizes the rapid disassembly and installation of the roller brush 105, which is conducive to improving the cleaning efficiency during operation and the daily rapid maintenance of the roller brush 105.

[0044] In this embodiment, the roller brush 102 is a wet mopping unit.

[0045] In this embodiment, please refer to Figures 1 to 2 The housing 103 also encloses a cleaning chamber 107, which is integrally formed with and parallel to the brush chamber 104.

[0046] In this embodiment, a cleaning unit 108 is installed inside the cleaning chamber 107, and the cleaning unit 108 can be used as a dry mopping unit.

[0047] In this embodiment, please refer to the reference. Figure 4 , Figure 5 and Figure 6 It also includes a drive unit 109 located on the inner wall of the housing 103, the drive unit 109 including a drive shaft 109a protruding from the inner wall surface of the housing 103 and a drive connector 109b sleeved on the drive shaft 109a.

[0048] In this embodiment, the driving unit 109 provides driving force to the roller brush 105, which, in conjunction with the roller brush shaft, enables the roller brush 105 to rotate, thereby achieving the function of mopping the floor.

[0049] In this embodiment, the drive connector 109b is detachably connected to the first end 105a, and the outer wall of the drive connector 109b has a protrusion 109c.

[0050] In this embodiment, please refer to Figure 5 and Figure 6 The drive connector 109b is a hexagonal spherical torque transmission structure. Due to the tight wrapping of the hexagonal shape, the torque transmission area is larger, so it can withstand greater torque and is not easily damaged, ensuring service life and thus improving the consumer experience.

[0051] In this embodiment, please refer to Figure 4 The elastic element 106 is integrated in the roller brush 105. Specifically, the first end 105a has an elastic cavity 111 recessed along a first direction, and the surface of the first end 105a exposes the opening of the elastic cavity. The first direction is parallel to the axial direction of the roller brush 105, and the elastic element 106 is located in the elastic cavity 111.

[0052] In this embodiment, the elastic element 106 is a spring.

[0053] In other embodiments, the elastic element 106 may also be a sponge, etc.

[0054] In other embodiments, the elastic element 106 may not be integrated into the roller brush 105. Specifically, one end of the elastic element 106 is sleeved on the drive connector 109b, and the other end of the elastic element 106 is in contact with the first end 105a of the roller brush 105. At this time, the elastic element 106 is in a state of no force.

[0055] In this embodiment, please refer to Figure 7 It also includes: a connector 110 covering the opening of the elastic cavity, the inner wall of the connector 110 having a groove 110a that matches and connects with the protrusion 109c.

[0056] In this embodiment, please refer to Figure 4 and Figure 8 It also includes a roller brush shaft 112 located on the inner wall of the housing 103, the roller brush shaft 112 being detachably connected to the second end 105b.

[0057] In this embodiment, please refer to Figure 4 and Figure 8It also includes a disassembly component 113 located between the second end 105b and the inner wall of the housing 103, the disassembly component 113 being sleeved on the roller brush shaft 112.

[0058] In this embodiment, the purpose of setting the disassembly component 113 is to facilitate the disassembly of the roller brush 105 on the one hand, and on the other hand, so that when the consumer disassembles and replaces the roller brush 105, there is no need to find additional auxiliary tools or apply disassembly force to the roller brush 105 by hand, thereby providing the consumer with a very satisfying experience during the replacement process.

[0059] In this embodiment, the disassembly component 113 includes a disassembly ring 113a sleeved on the roller brush shaft 112 and a disassembly handle 113b protruding from the disassembly ring 113a.

[0060] In this embodiment, the inner diameter of the disassembly ring 113a is larger than the outer diameter of the brush shaft 112.

[0061] In this embodiment, after the second end 105b is assembled with the roller brush shaft 112, there is a certain gap (d) between the disassembly handle 113b and the inner wall of the housing 103. The bottom of the disassembly ring 113a contacts the second end 105b, so that when the disassembly handle 113b is pressed subsequently (please refer to...), Figure 9 The second end 105b can only be lifted when the disassembly ring 113a is lifted.

[0062] In this embodiment, the disassembly handle 113b faces the opposite direction to the ground, which improves the overall aesthetics and also protects the disassembly component 113.

[0063] In other embodiments, the disassembly handle 113b may also face the ground.

[0064] In this embodiment, please refer to the reference. Figure 4 , Figure 8 and Figure 9 It also includes: a limiting buckle 116 located on the inner wall of the housing 103, the limiting buckle 116 being located above the roller brush shaft 112, and the disassembly handle 113b being limited within the limiting buckle 116.

[0065] In this embodiment, pressing the disassembly handle 113b causes it to tilt towards the inner wall of the housing 103, thereby lifting the bottom of the disassembly ring 113a (see reference). Figures 10 to 11Thus, when the second end 105b is pressed, the elastic element 106 is also compressed, and the second end 105b moves toward the first end 105a. The second end 105b quickly separates from the inner wall of the connected housing 103. At the moment of separation, the elastic element 106 tends to return to its initial state, which gives the roller brush 105 a reaction force, causing the second end 105b to quickly pop out of the roller brush cavity 104 (please refer to...). Figures 12 to 13 This allows the roller brush 105 to be disassembled. Its simple structure improves the ease of disassembly and assembly of the roller brush 105, and is highly efficient. It enables the rapid disassembly and installation of the roller brush 105, which is beneficial for improving the cleaning efficiency during operation and the daily rapid maintenance of the roller brush 105.

[0066] In this embodiment, please refer to Figures 1 to 2 The cleaning device 100 further includes a water supply unit 114, which is connected to the roller brush unit 102 and supplies water to the roller brush unit 102.

[0067] In this embodiment, the water supply unit 114 and the roller brush unit 102 are detachably connected.

[0068] In other embodiments, the water supply unit 114 and the roller brush unit 102 may also be fixedly connected.

[0069] After the water supply unit 114 is fixedly connected to the roller brush unit 102, the disassembly handle 113b of the disassembly component 113 is positioned facing the ground.

[0070] In this embodiment, the inner wall of the roller brush cavity 104 has a groove, and the bottom of the water supply part 114 has a buckle corresponding to the groove.

[0071] In this embodiment, the cleaning device 100 also has a navigation sensor 115.

[0072] In this embodiment, the roller brush structure 101 integrated in the cleaning device 100 has an elastic element 106. During the disassembly or replacement of the roller brush 105, only a disassembly force needs to be applied to the second end 105b to compress the elastic element 106. At this time, the roller brush 105 moves from the second end 105b to the first end 105a, and the second end 105b quickly separates from the inner wall of the connected housing 103. At the moment of separation, the elastic element 106 tends to return to its initial state, which gives the roller brush 105 a reaction force, causing the second end 105b to quickly pop out from the roller brush cavity 104, realizing the quick disassembly of the roller brush 105 and improving the maintainability of the cleaning device. The roller brush 105 of this cleaning device is simple to install and operate, has high stability, and is easy to disassemble for replacement or maintenance, making it convenient to use and providing a good user experience.
