[0002] In related-art sweeping and mopping cleaning devices, the cleaning roller is in fixed contact with the surface to be cleaned. When the surface to be cleaned is uneven, the cleaning roller can easily lose contact with the ground and pass over steps or deep pits on the surface to be cleaned, making it unable to effectively clean the junctions between steps or deep pits. Furthermore, when garbage particles are large, they cannot pass through the gap between the cleaning roller and the dust inlet guide ramp and enter the garbage bin, blocking the dust inlet channel or jamming the cleaning roller, causing the cleaning device to malfunction. Furthermore, when the cleaning roller is large, the ground pressure variable increases, increasing the operating resistance, causing increased operating force and affecting the user experience.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0034] It should be noted that the terms "first," "second," and so on in the specification, claims, and drawings of this application are used to distinguish different objects, rather than to describe a specific order. Furthermore, the terms "including," "having," and any variations thereof are intended to cover non-exclusive inclusions.

[0035] In this specification, for convenience, words and phrases indicating orientation or positional relationships, such as "middle," "upper," "lower," "front," "back," "vertical," "horizontal," "top," "bottom," "inside," and "outside," are used to illustrate the positional relationships of constituent elements with reference to the accompanying drawings. This is merely for the purpose of facilitating the description of this specification and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present disclosure. The positional relationships of constituent elements may be appropriately changed depending on the orientation of the constituent elements being described. Therefore, the present disclosure is not limited to the words and phrases described in the specification and may be appropriately replaced depending on the circumstances.

[0036] In this specification, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be interpreted broadly. For example, they can refer to fixed, removable, or integral connections; mechanical or electrical connections; direct connections, indirect connections through intermediaries, or internal communication between two components. Those skilled in the art will understand the meaning of these terms in this disclosure based on the specific circumstances.

[0037] In the sweeping and mopping integrated cleaning device in the related art, the cleaning roller is in fixed contact with the surface to be cleaned. When the surface to be cleaned is uneven, the cleaning roller is likely to not stick to the ground and pass over the steps or deep pits on the surface to be cleaned. The cleaning roller cannot effectively clean the step junctions or deep pits. Moreover, when the garbage particles are large, the garbage cannot enter the garbage box through the gap between the cleaning roller and the dust inlet guide slope, which will block the dust inlet channel or jam the cleaning roller, causing the cleaning device to work abnormally.

[0038] If the gap between the cleaning roller and the dust inlet guide slope is set too large, wet garbage will adhere to the surface of the dust inlet guide slope, and the garbage cannot be rolled into the garbage box during the operation of the cleaning roller, affecting the cleaning effect of the cleaning device.

[0039] Please refer to Figures 1 to 3 , Figure 1 This is a schematic structural diagram of a cleaning device provided in an embodiment of the present application. Figure 2 This is a schematic diagram of the exploded structure of a cleaning device provided in an embodiment of the present application. Figure 3 The present application aims to provide a cleaning device 100 and a cleaning machine to solve the technical problems in the related art that the cleaning device 100 has poor cleaning performance on uneven surfaces to be cleaned and the inlet channel is easily blocked by garbage.

[0040] Specifically, the cleaning device 100 includes a housing 10, a trash box assembly 20, and a cleaning head assembly 30. The housing 10 encloses a receiving cavity. The trash box assembly 20 is disposed on the housing 10 and within the receiving cavity. The cleaning head assembly 30 is rotatably connected to the housing 10 and includes a movable bracket 31 and a cleaning roller 32. The movable bracket 31 is rotatably connected to the housing 10, and the cleaning roller 32 is rotatably connected to the movable bracket 31. The cleaning roller 32 and the trash box assembly 20 are spaced apart, and the cleaning roller 32 and the movable bracket 31 are capable of rotating relative to the housing 10 in a first direction D1 and an opposite direction.

[0041] It can be understood that the cleaning device 100 of the embodiment of the present application can be, but is not limited to, a floor cleaning tool such as a cleaning machine, a sweeping robot, and a floor scrubber.

[0042] The cleaning device 100 of this embodiment includes the shell 10 (the shell 10 includes but is not limited to the tractor frame), and the shell 10 encloses a receiving cavity, which can be used to accommodate the garbage box assembly 20 and other structural parts of the cleaning device 100, and this application does not impose any restrictions on this.

[0043] The cleaning device 100 of this embodiment further includes the cleaning head assembly 30, which is rotatably connected to the shell 10. Specifically, the cleaning head assembly 30 includes the movable bracket 31, which is rotatably connected to the shell 10. Furthermore, the movable bracket 31 includes a main body 311, a first extension portion 312, and a second extension portion 313, wherein the first extension portion 312 and the second extension portion 313 are respectively provided at both ends of the main body 311, and the shell 10 includes a first side wall 12 and a second side wall 13 that are relatively spaced apart, the first extension portion 312 is provided on a side of the first side wall 12 that is away from the second side wall 13 and is rotatably connected to the first side wall 12, and the second extension portion 313 is provided on a side of the second side wall 13 that is away from the first side wall 12 and is rotatably connected to the second side wall 13.

[0044] The cleaning head assembly 30 of this embodiment also includes the cleaning roller 32, which is arranged in the main body 311 of the shell 10 and is rotatably connected to the shell 10. The cleaning roller 32 contacts the surface to be cleaned (the surface to be cleaned includes but is not limited to the ground) through rotation, removes stains and dust on the cleaning surface through physical friction, and can also bring garbage on the cleaning surface into the cleaning device 100 through physical friction and adhesion, and collects it through other structural parts of the cleaning device 100.

[0045] The cleaning device 100 of this embodiment further includes the trash box assembly 20. Specifically, the trash box assembly 20 is disposed on a side of the housing 10 close to the cleaning roller 32, and a trash inlet channel is formed between the trash box assembly 20 and the cleaning roller 32. The inlet channel is used to introduce trash into the interior of the cleaning device 100 and collect the trash through the trash box assembly 20.

[0046] In this embodiment, the trash box assembly 20 includes a trash box 21, a guide portion 22 and a shovel bar 23 connected in sequence. The trash box 21 is arranged on the shell 10, and the guide portion 22 is arranged between the trash box 21 and the cleaning roller 32 and extends in the direction toward the surface to be cleaned. The shovel bar 23 is arranged at one end of the guide portion 22 away from the trash box 21, and the shovel bar 23 is used to contact the surface to be cleaned and shovel garbage into the inlet channel.

[0047] The shovel bar 23 is a flexible member, and the material of the shovel bar 23 includes but is not limited to soft rubber. The shovel bar 23 can be used to adapt to the different heights of the surface to be cleaned according to its own deformation, so that the shovel bar 23 and the surface to be cleaned are kept in close contact. In addition, in order to make the shovel bar 23 fit the cleaning surface more closely, there is a pre-pressure between the shovel bar 23 and the cleaning surface. It can be understood that there is a pre-pressure between the shovel bar 23 and the cleaning surface, that is, there is a certain pre-applied pressure or force between the shovel bar 23 and the surface to be cleaned to ensure close contact or fixation between the shovel bar 23 and the surface to be cleaned. The guide part 22 is a rigid part. The guide part 22 is a support for the shovel bar 23 to increase the rigidity. It can avoid the deformation of the guide part 22 when the cleaning device 100 passes over a bump or encounters a large obstacle, and it can also ensure that there is a pre-pressure between the shovel bar 23 and the cleaning surface. This ensures that the shovel bar 23 can better fit the cleaning surface, which is beneficial to improving the cleaning performance of the cleaning device 100. Furthermore, the guide portion 22 is a bent structure and an inwardly concave structure, which is conducive to guiding the garbage and preventing the garbage from falling out of the introduction channel. Optionally, the guide portion 22 includes but is not limited to materials such as plastic and metal.

[0048] Furthermore, the guide portion 22 has a mounting portion at one end away from the trash box 21, and the mounting portion is used to mount the shovel bar 23. Optionally, in this embodiment, the shovel bar 23 is assembled on the guide portion 22 by side insertion, and the guide portion 22 and the trash box 21 are an integral structure. In other words, the guide portion 22 and the trash box 21 are integrally manufactured through a single process. Alternatively, the guide portion 22 and the trash box 21 may be separate structures, and the guide portion 22 and the trash box 21 may be fixed by a connection. The connection is not limited to fixing methods such as screws or snaps. For the sake of convenience of description, this application distinguishes and names them, which should not be understood as limiting this application. In other embodiments, the shovel bar 23 may be fixed to the guide portion 22 by screws or other methods, or the trash box 21, the guide portion 22, and the shovel bar 23 may be injection molded once or multiple times. This application does not impose any restrictions on this.

[0049] It should be noted that the cleaning device 100 includes a depressed state, a normal state, and an elevated state. Specifically, the cleaning head assembly 30 can rotate relative to the housing 10 so that the cleaning device 100 is in the depressed state, the normal state, and the elevated state, respectively. Figure 4 As shown, Figure 4 1 is a schematic structural diagram of a cleaning device in a depressed state provided by an embodiment of the present application. The cleaning device 100 is in a depressed state. When the cleaning device 100 is in a depressed state, the main body 311 of the movable bracket 31 abuts against the bottom of the housing 10, and the distance between the rotation center of the cleaning roller 32 and the bottom surface of the housing 10 is a first distance. Figure 5 As shown, Figure 5 1 is a schematic structural diagram of a cleaning device in a normal state provided by an embodiment of the present application. The cleaning device 100 is in a normal state. When the cleaning device 100 is in a normal state, the distance between the rotation center of the cleaning roller 32 and the bottom surface of the housing 10 is a second distance. Figure 6 As shown, Figure 6 2 is a schematic structural diagram of a cleaning device in a raised state provided by an embodiment of the present application. The cleaning device 100 is in the raised state. When the cleaning device 100 is in the raised state, the distance between the rotation center of the cleaning roller 32 and the bottom surface of the housing 10 is a third distance. The first distance is smaller than the second distance, and the second distance is smaller than the third distance. In other words, the height of the cleaning roller 32 increases sequentially when the cleaning device 100 is in the depressed state, normal state, and raised state, respectively.

[0050] It should be noted that, when the cleaning device 100 is in a normal state, in order to make the cleaning roller 32 fit more closely to the surface to be cleaned, there is a pre-pressure between the cleaning roller 32 and the surface to be cleaned. It can be understood that there is a pre-pressure between the cleaning roller 32 and the surface to be cleaned, that is, there is a certain pre-applied pressure or force between the cleaning roller 32 and the surface to be cleaned. Let this pre-pressure be F1 to ensure close contact or fit between the cleaning roller 32 and the surface to be cleaned.

[0051] It should be further explained that when the cleaning device 100 is cleaning a raised or stepped surface, the pressure between the cleaning roller 32 and the surface to be cleaned is greater than F1, and the cleaning roller 32 and the movable bracket 31 can rotate relative to the housing 10 in the first direction D1 to put the cleaning device 100 into an elevated state. When the cleaning device 100 is cleaning a concave or downwardly inclined surface, the pressure between the cleaning roller 32 and the surface to be cleaned is less than F1, and the cleaning roller 32 and the movable bracket 31 can rotate relative to the housing 10 in the opposite direction of the first direction D1 to put the cleaning device 100 into a depressed state. For the convenience of the following description, the direction opposite to the first direction D1 is named the second direction D2, which should not be understood as a limitation of this application.

[0052] Furthermore, the cleaning roller 32 of the cleaning head assembly 30 abuts the surface to be cleaned. When the cleaning device 100 encounters a deep pit on the cleaning path during the cleaning process, the cleaning roller 32 and the movable bracket 31 descend due to their own gravity or the action of the elastic component and rotate along the second direction D2 relative to the shell 10, so that the cleaning roller 32 enters the deep pit and can effectively clean the surface of the deep pit.

[0053] When the cleaning device 100 is in the cleaning process and larger particles of garbage are trapped between the cleaning roller 32 and the shovel bar 23 or the guide portion 22, the rotation of the cleaning roller 32 causes the garbage to squeeze the cleaning roller 32 itself. The cleaning roller 32 is driven by the squeezing force and drives the movable bracket 31 to rotate relative to the shell 10 along the first direction D1, so that the size of the introduction channel between the shovel bar 23 and the cleaning roller 32 is increased, so that larger particles of garbage can enter the garbage box 21 from the introduction channel and be collected, thereby improving the garbage recovery rate of the cleaning device 100.

[0054] Similarly, when the cleaning device 100 encounters obstacles such as steps and protrusions on the cleaning path, the cleaning roller 32 of the cleaning head assembly 30 will be driven by the extrusion force and squeezed upward, driving the movable bracket 31 to rotate relative to the housing 10 along the first direction D1. In other words, the cleaning roller 32 of the cleaning head assembly 30 will move upward in the vertical direction so that the cleaning roller 32 can cross obstacles such as steps and protrusions, thereby improving the crossing ability of the cleaning device 100 and not damaging the cleaning surface. Moreover, after the cleaning device 100 crosses the step, the cleaning roller 32 of the cleaning head assembly 30 drives the movable bracket 31 to rotate relative to the housing 10 along the second direction D2 due to its own gravity or the action of the elastic component, so that the cleaning roller 32 can effectively clean the surface after passing the step, thereby improving the cleaning efficiency of the cleaning device 100.

[0055] Please refer to Figures 1 to 6 In the cleaning device 100 provided in the present application, the garbage box assembly 20 is arranged in the receiving cavity of the shell 10, the cleaning head assembly 30 is rotatably connected to the shell 10, and the cleaning head assembly 30 includes the movable bracket 31 and the cleaning roller 32. The movable bracket 31 is rotatably connected to the shell 10, and the cleaning roller 32 is rotatably connected to the movable bracket 31. The cleaning roller 32 and the garbage box assembly 20 are arranged at intervals, and the cleaning roller 32 and the movable bracket 31 can rotate relative to the shell 10 along the first direction D1 and the opposite direction. The cleaning roller 32 of the cleaning head assembly 30 abuts the surface to be cleaned. When larger particles of garbage are trapped between the cleaning roller 32 and the shovel bar 23 or the guide portion 22 during the cleaning process of the cleaning device 100, the rotation of the cleaning roller 32 causes the garbage to squeeze the cleaning roller 32 itself. The cleaning roller 32 is subjected to a thrust and drives the movable bracket 31 to rotate relative to the shell 10 along the first direction D1, so that the size of the introduction channel between the shovel bar 23 and the cleaning roller 32 is increased, so that larger particles of garbage can enter the garbage box 21 from the introduction channel and be collected, thereby improving the garbage recovery rate of the cleaning device 100. Moreover, when the cleaning device 100 encounters uneven roads such as steps and deep pits on the cleaning path, the cleaning roller 32 and the movable bracket 31 can rotate relative to the shell 10 along the first direction D1 or the second direction D2, so that the cleaning roller 32 can cross the steps for cleaning or enter the deep pit and clean the surface of the deep pit, thereby improving the bump-crossing ability and cleaning efficiency of the cleaning device 100.

[0056] It should be noted that during the preparation process of the cleaning roller 32, the size of the cleaning roller 32 may deviate to a certain extent. In the cleaning device in the related art, when the size of the cleaning roller deviates, it will lead to poor contact between the cleaning roller and the surface to be cleaned. For example, when the size of the cleaning roller is too large, the contact area between the cleaning roller and the surface to be cleaned is large, and the friction force is large, resulting in the need to increase the cleaning operation force required by the cleaning device; when the size of the cleaning roller is too small, the contact area between the cleaning roller and the surface to be cleaned is reduced or cannot contact the surface to be cleaned at all, resulting in the cleaning device being unable to perform normal cleaning operations.

[0057] In the cleaning device 100 provided in the present application, even if there is a certain deviation in the size of the cleaning roller 32, the cleaning roller 32 and the movable bracket 31 can rotate relative to the shell 10 along the first direction D1 and the opposite direction to ensure normal contact between the cleaning roller 32 and the surface to be cleaned, which can reduce the manufacturing accuracy requirements of the cleaning roller 32.

[0058] Please refer to Figure 2 、 Figure 7 and Figure 8 , Figure 7 This is a partial cross-sectional structural diagram of a cleaning device provided in an embodiment of the present application. Figure 8 yes Figure 7 Schematic diagram of the enlarged structure of area A in the middle.

[0064] Please refer to Figure 1 and Figure 2 In one embodiment, the cleaning head assembly 30 further includes an elastic assembly 34 , and the elastic assembly 34 is respectively connected to the movable bracket 31 and the side wall of the shell 10 .

[0065] It should be noted that, in this embodiment, the side walls of the shell 10 include the first side wall 12 and the second side wall 13. In this embodiment, the elastic component 34 is provided on the first side wall 12 for schematic illustration. In other embodiments, the elastic component 34 may also be provided on the second side wall 13 and respectively connected to the second extension portion 313 and the second side wall 13. This application does not impose any restrictions on this.

[0066] In one embodiment, a first fixing member 14 is provided on the side wall of the shell 10, and the first fixing member 14 is provided on one side of the movable bracket 31. The elastic component 34 includes a first elastic member 341, and the first elastic member 341 is respectively connected to the first fixing member 14 and the movable bracket 31.

[0067] Optionally, the first fixing member 14 is arranged on the side of the first extension portion 312 of the movable bracket 31 away from the surface to be cleaned, and the first elastic member 341 is respectively connected to the first fixing member 14 and the first extension portion 312, the first elastic member 341 has elastic potential energy, and the first elastic member 341 can be used to apply a force along the second direction D2 to the first extension portion 312 and the movable bracket 31, so that the first extension portion 312 can drive the main body 311 and the cleaning roller 32 to rotate along the second direction D2. That is, when the cleaning device 100 passes over a ridge or receives larger garbage particles, the cleaning roller 32 drives the movable bracket 31 to move along the first direction D1, and the first elastic member 341 contracts and increases its elastic potential energy. When the cleaning device 100 passes over a ridge or the larger garbage particles have passed through the introduction channel, the first elastic member 341 restores its deformation while pushing the movable bracket 31 and the cleaning roller 32 to move along the second direction D2 for reset, so that the pre-pressure between the cleaning roller 32 and the surface to be cleaned is restored and the surface to be cleaned is cleaned.

[0068] In other embodiments, the first fixing member 14 and the first elastic member 341 may also be arranged on the side of the first extension portion 312 facing the surface to be cleaned. The above all belong to the embodiments of the present application and should not be understood as limitations of the present application.

[0069] Optionally, in this embodiment, the first elastic member 341 is a cylindrical spring. In other embodiments, the first elastic member 341 can also be a torsion spring, a spring, a tower spring or other elastic structural member, and this application does not impose any restrictions on this.

The elastic assembly 34 includes a first elastic member 341 and a second elastic member 342, and the first elastic member 341 and the second elastic member 342 are respectively provided on either side of the movable bracket 31, with the first elastic member 341 respectively connecting the first fixing member 14 and the movable bracket 31, and the second elastic member 342 respectively connecting the second fixing member 15 and the movable bracket 31. The first elastic member 341 and the second elastic member 342 are respectively provided on either side of the first extension portion 312, which facilitates faster reset of the movable bracket 31 and the cleaning roller 32 after movement, thereby improving the cleaning efficiency of the cleaning device 100.

[0071] Furthermore, when the cleaning roller 32 is larger in size, the pre-pressure between the cleaning roller 32 and the surface to be cleaned is larger, the second elastic member 342 contracts and increases the elastic potential energy, and the cleaning device 100 is lifted and fine-tuned to a position of elastic balance with the first elastic member 341, so that the pre-pressure between the cleaning roller 32 and the surface to be cleaned is self-adjusted to a suitable position, so that the cleaning resistance of the machine is reduced and the operation force is easy; on the contrary, when the cleaning roller 32 is smaller in size, the pre-pressure between the cleaning roller 32 and the surface to be cleaned is smaller, or the cleaning roller 32 does not abut the surface to be cleaned, the first elastic member 341 contracts and increases the elastic potential energy, and the cleaning device 100 is pressed down and fine-tuned to a position of elastic balance with the second elastic member 342, so that the pre-pressure between the cleaning roller 32 and the surface to be cleaned is restored and the surface to be cleaned is cleaned.

[0072] The angle α between the arrangement direction of the first elastic member or the second elastic member and the extension direction of the movable bracket satisfies the following conditions: 0°≤α≤90°. Optionally, α includes, but is not limited to, 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80°, 90°, or other values ​​within the range of 0°-90°.

[0073] Furthermore, in one embodiment, the first elastic member 341 is disposed in a direction perpendicular to the extension direction of the movable bracket 31, and the second elastic member 342 is disposed in a direction perpendicular to the extension direction of the movable bracket 31. Specifically, the first elastic member 341 and the second elastic member 342 are disposed in directions perpendicular to the first extension portion 312, so that the first elastic member 341 and the second elastic member 342 can provide a greater elastic support force to the first extension portion 312.

[0074] In one embodiment, the side wall of the shell 10 is provided with a first slide rail portion 16, and the first slide rail portion 16 is bent in a direction away from the rotating shaft 33. The movable bracket 31 is provided with a second slide rail portion 314, and the second slide rail portion 314 cooperates with the first slide rail portion 16 to enable the movable bracket 31 to rotate along the first slide rail portion 16.

[0075] In this embodiment, the first slide rail portion 16 and the second slide rail portion 314 are arc-shaped, and the first slide rail portion 16 and the second slide rail portion 314 cooperate to facilitate the movable bracket 31 to rotate relative to the shell 10 along the first direction D1 and the second direction D2, thereby avoiding misalignment of the movable bracket 31 during rotation.

[0076] Please refer to Figure 4 In one embodiment, the side wall of the shell 10 is provided with a first blocking portion 17 and a second blocking portion 18, and the first blocking portion 17 and the second blocking portion 18 are respectively provided on both sides of the movable bracket 31, and the first blocking portion 17 is provided on the side of the movable bracket 31 away from the surface to be cleaned. The first blocking portion 17 is used to limit the rotation of the movable bracket 31 along the first direction D1, so as to prevent the movable bracket 31 and the cleaning roller 32 from rotating excessively along the first direction D1 so as to cause the cleaning roller 32 to separate from the surface to be cleaned.

[0077] The second blocking portion 18 is arranged on the side of the movable bracket 31 facing the surface to be cleaned. The second blocking portion 18 is used to limit the movable bracket 31 from rotating in the opposite direction of the first direction D1, thereby preventing the movable bracket 31 and the cleaning roller 32 from excessively rotating in the second direction D2 so that the cleaning roller 32 exerts too much pressure on the surface to be cleaned, thereby affecting the normal operation of the cleaning device 100.

[0078] Please refer to Figure 2 and Figure 9 , Figure 9 It is a structural schematic diagram of a cleaning head assembly provided in an embodiment of the present application.

[0079] In one embodiment, the cleaning head assembly 30 also includes a pre-scraping bar 35, a filter screen 36 and a water squeezing bar 37 fixed in the main body 311, and the pre-scraping bar 35, the filter screen 36 and the water squeezing bar 37 are arranged in sequence along the second direction D2, and a sealed flow water channel is formed between the pre-scraping bar 35, the filter screen 36 and the water squeezing bar 37, and the pre-scraping bar 35 and the water squeezing bar 37 abut the cleaning roller 32 to squeeze out the sewage in the cleaning roller 32 and filter it into the sealed flow water channel through the filter screen 36.

[0080] Furthermore, the first extension portion 312 and the second extension portion 313 of the movable bracket 31 are respectively provided with a clean water channel 38 and a sewage channel 39. Optionally, the clean water channel 38 can be provided on the first extension portion 312 and the sewage channel 39 can be provided on the second extension portion 313, or the sewage channel 39 can be provided on the first extension portion 312 and the clean water channel 38 can be provided on the second extension portion 313, and this is not limited in this application. The clean water channel 38 and the sewage channel 39 are respectively connected to the sealed flow water channel. The clean water channel 38 is connected to the clean water tank, and is used to guide clean water in the clean water tank into the sealed flow water channel and clean the cleaning roller 32. It can also flush sewage from the sealed flow water channel into the sewage channel 39. The sewage channel 39 is connected to the sewage tank, and is used to guide sewage to the sewage tank for collection. Furthermore, the rotating shaft 33 can be used to connect the clean water channel 38 or the sewage channel 39.

[0081] Please refer to Figure 6 In one embodiment, the cleaning device 100 further includes a brush roller 40, which is disposed in the receiving cavity and rotatably connected to the shell 10. The brush roller 40 is disposed on the side of the garbage box assembly 20 away from the surface to be cleaned, and the brush roller 40 is used to sweep the garbage on the cleaning roller 32 to the garbage box assembly 20.

[0082] Specifically, the brush roller 40 is disposed above the trash box 21. When rotating, the brush roller 40 abuts against the cleaning roller 32 and is used to remove trash adhered to the outer surface of the cleaning roller 32 into the trash box 21. Specifically, after the cleaning roller 32 cleans the surface to be cleaned, larger trash such as hair may adhere to the surface of the cleaning roller 32. When rotating, the brush roller 40 abuts against the cleaning roller 32 and removes the larger trash such as hair into the trash box 21, thereby preventing the trash on the cleaning roller 32 from continuing to adhere to the cleaning roller 32, thereby improving the trash collection efficiency of the cleaning device 100.

[0083] Please refer to Figures 1 to 9 The present application also provides a cleaning machine, which includes a device body and the cleaning device 100, and the cleaning device 100 is arranged on the device body.

[0084] The device body includes but is not limited to a handle structure. The device body can be used to accommodate structural parts such as a clean water tank and a sewage tank. The device body can also be used for a user to hold and control the movement of the cleaning device 100 through the device body.

[0085] In the cleaning machine provided in the present application, the garbage box assembly 20 is arranged in the receiving cavity of the shell 10, the cleaning head assembly 30 is rotatably connected to the shell 10, the cleaning head assembly 30 includes the movable bracket 31 and the cleaning roller 32, the movable bracket 31 is rotatably connected to the shell 10, the cleaning roller 32 is rotatably connected to the movable bracket 31, the cleaning roller 32 and the garbage box assembly 20 are spaced apart, and the cleaning roller 32 and the movable bracket 31 can rotate relative to the shell 10 along the first direction D1 and the opposite direction. The cleaning roller 32 of the cleaning head assembly 30 abuts the surface to be cleaned. When larger particles of garbage are trapped between the cleaning roller 32 and the shovel bar 23 or the guide portion 22 during the cleaning process, the rotation of the cleaning roller 32 causes the garbage to squeeze the cleaning roller 32 itself, and the cleaning roller 32 is subjected to a thrust force and drives the movable bracket 31 to rotate relative to the housing 10 in the first direction D1, thereby increasing the size of the inlet channel between the shovel bar 23 and the cleaning roller 32. This allows larger particles of garbage to enter the garbage bin 21 through the inlet channel and be collected, thereby improving the garbage recovery rate of the cleaning machine. In addition, when the cleaning machine encounters uneven surfaces such as steps or deep pits on its cleaning path, the cleaning roller 32 and the movable bracket 31 can rotate relative to the housing 10 in the first direction D1 or the second direction D2, allowing the cleaning roller 32 to clean the steps or enter the deep pits and clean the surface of the deep pits, thereby improving the cleaning machine's ability to pass over bumps and cleaning efficiency.
