DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present 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", etc. in the specification and claims of this application and the above drawings are used to distinguish different objects rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0035] In this specification, for the sake of convenience, the words and phrases indicating the orientation or positional relationship such as "middle", "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like are used to illustrate the positional relationship of the constituent elements with reference to the drawings. This is only for the convenience of describing this specification and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation of the present disclosure. The positional relationship of the constituent elements is appropriately changed according to the orientation of the constituent elements being described. Therefore, it is not limited to the words and phrases described in the specification, and can be appropriately replaced according to the circumstances.

[0036] In this specification, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate, or the internal communication of two elements. For ordinary technicians in this field, the meanings of the above terms in this disclosure can be understood according to the circumstances.

[0037] In the sweeping and mopping 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 go over the steps or deep pits on the surface to be cleaned. The cleaning roller cannot effectively clean the step joints 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 entry guide slope, which will block the dust entry 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 directly set larger, 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 is a schematic structural diagram of a cleaning device provided in an embodiment of the present application, Figure 2 is a schematic diagram of an 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 introduction 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 disposed in the receiving cavity. The cleaning head assembly 30 is rotatably connected to the housing 10, and the cleaning head assembly 30 includes a movable bracket 31 and a cleaning roller 32, the movable bracket 31 is rotatably connected to the housing 10, 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 can rotate relative to the housing 10 along a first direction D1 and the opposite direction thereof.

[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 a tractor frame), and the shell 10 encloses a receiving cavity, which can be used to receive the garbage box assembly 20 and other structural parts of the cleaning device 100, and the present application does not impose any limitation on this.

[0043] The cleaning device 100 of this embodiment further includes the cleaning head assembly 30, and the cleaning head assembly 30 is rotatably connected to the shell 10. Specifically, the cleaning head assembly 30 includes the movable bracket 31, and the movable bracket 31 is rotatably connected to the shell 10. Further, the movable bracket 31 includes a main body 311, a first extension portion 312 and a second extension portion 313, the first extension portion 312 and the second extension portion 313 are respectively arranged at both ends of the main body 311, and the shell 10 includes a first side wall 12 and a second side wall 13 arranged relatively spaced apart, the first extension portion 312 is arranged on a side of the first side wall 12 away from the second side wall 13 and is rotatably connected to the first side wall 12, and the second extension portion 313 is arranged on a side of the second side wall 13 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 disposed 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 collect 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 shell 10 close to the cleaning roller 32, and the trash box assembly 20 and the cleaning roller 32 are spaced apart to form a trash introduction channel, and the introduction channel is used to introduce the trash into the interior of the cleaning device 100 and collect it through the trash box assembly 20.

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

[0047] The shovel bar 23 is a flexible part, 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 surface to be cleaned of different heights 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 the close contact or fixation between the shovel bar 23 and the surface to be cleaned. The guide part 22 is a rigid part, and the guide part 22 is a support for the shovel bar 23 to improve the rigidity, which can avoid the deformation of the guide part 22 when the cleaning device 100 passes a hurdle or encounters a large obstacle, and there can be a pre-pressure between the shovel bar 23 and the cleaning surface. Thereby ensuring that the shovel bar 23 can better fit the cleaning surface, which is conducive to improving the cleaning performance of the cleaning device 100. Furthermore, the guide portion 22 is a bent structure, and the guide portion 22 is 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 plastic, metal and other materials.

[0048] Further, 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 integrated structure. In other words, the guide portion 22 and the trash box 21 are integrally prepared through a process, or the guide portion 22 and the trash box 21 are a split structure, and the guide portion 22 and the trash box 21 are fixed by connection, and the connection is not limited to fixing by screws or snaps. For the 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 can also be fixed to the guide portion 22 by screws or other directions, or the trash box 21, the guide portion 22 and the shovel bar 23 can be injection molded once or multiple times, and this application does not limit 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 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 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 1 is a schematic diagram of a cleaning device in a raised state provided by an embodiment of the present application, wherein the cleaning device 100 is in a raised state, and when the cleaning device 100 is in a 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, when the cleaning device 100 is in a depressed state, a normal state, and a raised state, the height of the cleaning roller 32 increases in sequence.

[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. Suppose this pre-pressure is 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 cleans 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 along the first direction D1, so that the cleaning device 100 enters a raised state; when the cleaning device 100 cleans a concave surface or a 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 along the opposite direction of the first direction D1, so that the cleaning device 100 enters a depressed state. For the convenience of the following description, the opposite direction of the first direction D1 is named the second direction D2, which should not be understood as a limitation to the present application.

[0052] Furthermore, the cleaning roller 32 of the cleaning head assembly 30 abuts against 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 sandwiched 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 shell 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, improve the crossing ability of the cleaning device 100, and will not damage the cleaning surface. In addition, when 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 shell 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, so as to improve 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 accommodating 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 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 against the surface to be cleaned. When larger particles of garbage are sandwiched 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. Furthermore, 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 go over the steps for cleaning or enter the deep pit and clean the surface of the deep pit, thereby improving the hill-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 does not 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 the size of the cleaning roller 32 deviates to a certain extent, 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 is a partial cross-sectional structural schematic 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.

[0059] In one embodiment, a mounting through hole 11 is provided on the side wall of the housing 10, and the cleaning head assembly 30 further includes a rotating shaft 33, at least a portion of which is disposed in the mounting through hole 11 and can rotate relative to the side wall of the housing 10, and the movable bracket 31 is connected to the rotating shaft 33. If the structural space permits, the rotating shaft 33 can also be made into one piece with the movable bracket 31. It should be noted that the present application does not limit how the rotating shaft 33 is fixed in the mounting through hole 11, and it should not be understood as a limitation on the present application.

[0060] Specifically, in one embodiment, the rotating shaft member 33 includes a connected rotating shaft body 331 and a rotating shaft sleeve 332, the rotating shaft body 331 is arranged in the mounting through hole 11 and connected to the movable bracket 31, the rotating shaft sleeve 332 is arranged on the side of the rotating shaft body 331 away from the movable bracket 31, and the rotating shaft sleeve 332 is provided with a guard edge, and the radial dimension of the guard edge is larger than the radial dimension of the mounting through hole 11, and the rotating shaft sleeve 332 and the movable bracket 31 cooperate to limit the rotating shaft body 331 in the mounting through hole 11.

[0061] It should be noted that, in the present embodiment, the side wall of the shell 10 includes the first side wall 12 and the second side wall 13. In the present embodiment, the first side wall 12 is provided with the mounting hole 11 for schematic illustration. In other embodiments, the second side wall 13 may also be provided with the mounting hole 11 and the rotating shaft 33 may be installed. The number of the rotating shaft 33 may be 2, and the present application does not impose any limitation on this.

[0062] Specifically, in this embodiment, the shaft body 331 is disposed in the mounting hole 11 of the first side wall 12, and the shaft body 331 is connected to the first extension portion 312 of the movable bracket 31, and the retaining edge of the shaft sleeve 332 is disposed on the side of the shaft body 331 away from the first extension portion 312, and the retaining edge of the shaft sleeve 332 and the first extension portion 312 cooperate to limit the shaft body 331 to the mounting hole 11 of the first side wall 12.

[0063] It should be noted that, in this embodiment, the steps for installing the rotating shaft member 33 are as follows: first, the movable bracket 31 is installed on the housing 10, the first extension portion 312 is attached to the first side wall 12 of the housing 10, and the second extension portion 313 is attached to the second side wall 13 of the housing 10, and then one of the rotating shaft members 33 is passed through the installation through hole 11 of the first side wall 12 and aligned with the first extension portion 312, and the first extension portion 312 and the rotating shaft member 33 are connected by screws to fix the first extension portion 312 and the rotating shaft member 33 to the first side wall 12. It should be noted that the second extension portion 313 is also fixed to the second side wall 13 by cooperating with one of the rotating shaft members 33, and this application will not repeat this.

[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 the present embodiment, the side wall of the shell 10 includes the first side wall 12 and the second side wall 13. In the present 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 connect the second extension portion 313 and the second side wall 13. The present 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 construed as limitations to 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 may also be a torsion spring, a spring sheet, a tower spring or other elastic structural member, which is not limited in the present application.

[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 force 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 operating 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 against 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 force 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 between the setting direction of the first elastic member or the second elastic member and the extending direction of the movable bracket is α, and the α satisfies: 0°≤α≤90°. Optionally, the α includes but is not limited to 10°, or 20°, or 30°, or 40°, or 50°, or 60°, or 70°, or 80°, or 90°, or other values ​​within the range of 0°-90°.

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

[0074] In one embodiment, a first slide rail portion 16 is provided on the side wall of the shell 10, and the first slide rail portion 16 is bent in a direction away from the rotating shaft 33. A second slide rail portion 314 is provided on the movable bracket 31, 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 in an arc shape, 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 arranged on both sides of the movable bracket 31, and the first blocking portion 17 is arranged on the side of the movable bracket 31 away from the surface to be cleaned, and the first blocking portion 17 is used to limit the movable bracket 31 from rotating 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, and the second blocking portion 18 is used to limit the movable bracket 31 from rotating in the opposite direction of the first direction D1, so as to prevent 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 Fig. 9 , Fig. 9 It is a schematic structural 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 strip 35, a filter screen 36 and a water squeezing strip 37 fixed in the main body 311, and the pre-scraping strip 35, the filter screen 36 and the water squeezing strip 37 are arranged in sequence along the second direction D2, and a sealed flow water channel is formed between the pre-scraping strip 35, the filter screen 36 and the water squeezing strip 37, and the pre-scraping strip 35 and the water squeezing strip 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] Further, the first extension part 312 and the second extension part 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 part 312, and the sewage channel 39 can be provided on the second extension part 313, or the sewage channel 39 can be provided on the first extension part 312, and the clean water channel 38 can be provided on the second extension part 313, and the present application does not limit this. The clean water channel 38 and the sewage channel 39 are respectively connected to the sealed flowing waterway, and the clean water channel 38 is connected to the clean water tank, so as to allow the clean water in the clean water tank to be introduced into the sealed flowing waterway and clean the cleaning roller 32, and can flush the sewage in the sealed flowing waterway into the sewage channel 39, and the sewage channel 39 is connected to the sewage tank, so as to guide the sewage to the sewage tank, so as to collect the sewage. Further, 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 chamber and rotatably connected to the shell 10, and the brush roller 40 is disposed on a 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. The brush roller 40 abuts against the cleaning roller 32 when rotating, and is used to brush away the 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 be attached to the surface of the cleaning roller 32. The brush roller 40 abuts against the cleaning roller 32 when rotating, and brushes away the larger trash such as hair into the trash box 21, so as to prevent 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 cleaning device 100 to move through the device body.

[0085] In the cleaning machine provided in the present application, the garbage box assembly 20 is arranged in the accommodating 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 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 against the surface to be cleaned. When the cleaning machine is cleaning, there are large particles of garbage sandwiched between the cleaning roller 32 and the shovel bar 23 or the guide part 22. The rotation of the cleaning roller 32 causes the garbage to squeeze the cleaning roller 32 itself. The cleaning roller 32 is thrust and drives the movable bracket 31 to rotate relative to the housing 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 large 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 machine. In addition, when the cleaning machine 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 housing 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 crossing ability and cleaning efficiency of the cleaning machine.
