Specific embodiments

[0031] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present application.

[0032] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion.

[0033] In this specification, for convenience, terms indicating orientation or positional relationship such as "middle", "upper", "lower", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are used to describe the positional relationship of the constituent elements with reference to the accompanying drawings. It is only for the convenience of describing this specification and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present disclosure. The positional relationship of the constituent elements is appropriately changed according to the direction of the described constituent elements. Therefore, it is not limited to the terms described in this specification, and can be appropriately replaced according to the situation.

[0034] In this specification, unless otherwise clearly defined and limited, the terms "installed", "connected", and "coupled" shall 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, an indirect connection through an intermediate member, or the communication inside two components. For those of ordinary skill in the art, the meanings of the above terms in this disclosure can be understood according to the circumstances.

[0035] In the integrated sweeping and mopping cleaning device in the related art, when the ground is uneven or there are steps, the scraping strip will not be in contact with the ground or be blocked by the steps and cannot move normally; and when the garbage particles are relatively large, the garbage cannot enter the garbage box through the gap between the cleaning roller and the dust inlet guiding inclined surface, which will block the dust inlet passage or jam the cleaning roller, resulting in abnormal operation of the cleaning device.

[0036] If the gap between the cleaning roller and the dust inlet guiding inclined surface is directly set to be relatively large, the wet garbage will adhere to the surface of the dust inlet guiding inclined surface and cannot be rolled into the garbage box during the operation of the cleaning roller, affecting the cleaning effect of the cleaning device.

[0037] Please refer to Figures 1 to 3 , Figure 1 which is a schematic cross-sectional structure of a cleaning device provided by an embodiment of the present application in a first state. Figure 1 , Figure 2 which is a schematic cross-sectional structure diagram of a cleaning device provided by an embodiment of the present application in a state of collecting relatively large particle garbage. Figure 3 which is a schematic cross-sectional structure diagram of a cleaning device provided by an embodiment of the present application in a state of crossing a step.

[0038] The present application provides a cleaning device 100 to solve the technical problems in the related art that the cleaning device has poor performance in crossing steps and is easily blocked by garbage in the inlet channel.

[0039] Specifically, the cleaning device 100 includes a housing 10, a cleaning roller 20, a movable bracket 30, and a garbage box assembly 40. The housing 10 encloses to form a receiving cavity. The cleaning roller 20 is disposed in the receiving cavity and is rotatably connected to the housing 10. The movable bracket 30 and the garbage box assembly 40 are disposed in the receiving cavity. The movable bracket 30 is slidably connected to the housing 10 and can reciprocally move relative to the housing 10 along a first direction D1. The garbage box assembly 40 is disposed on the movable bracket 30 and on a side of the movable bracket 30 facing the cleaning roller 20. The garbage box assembly 40 can drive the movable bracket 30 to reciprocally move along the first direction D1, wherein the first direction D1 forms an angle with the cleaning surface.

[0040] Understandably, the cleaning device 100 of the embodiments of the present application can be, but is not limited to, ground cleaning tools such as cleaning machines, floor sweeping robots, and floor washing machines.

[0041] The cleaning device 100 of this embodiment includes the housing 10 (the housing 10 includes, but is not limited to, a mop head frame), the housing 10 encloses to form a receiving cavity, and the receiving cavity can be used to receive the cleaning roller 20, the movable bracket 30, the trash box assembly 40 and other structural members of the cleaning device 100, and the present application does not limit this.

[0042] The cleaning device 100 of this embodiment further includes the cleaning roller 20, and the cleaning roller 20 is disposed in the receiving cavity and rotatably connected to the housing 10. The cleaning roller 20 contacts the cleaning surface (the cleaning surface includes, but is not limited to, the ground) by rotation, removes stains and dust on the cleaning surface through physical friction, and can also bring the garbage on the cleaning surface into the cleaning device 100 through physical friction and adhesion, and is collected by other structural members of the cleaning device 100.

[0043] The cleaning device 100 of this embodiment further includes the trash box assembly 40 and the movable bracket 30, and the trash box assembly 40 is disposed on the movable bracket. Specifically, the trash box assembly 40 is disposed on one side of the movable bracket close to the cleaning roller 20, and a gap is provided between the trash box assembly 40 and the cleaning roller 20 to form a garbage inlet channel, and the inlet channel is used to introduce garbage into the interior of the cleaning device 100 and collect it through the trash box assembly 40.

[0044] Please refer to Figures 1 to 5 , Figure 4 which is a schematic structural diagram of a trash box provided by an embodiment of the present application, Figure 5 which is a schematic cross-sectional structural diagram of a trash box provided by an embodiment of the present application. In this embodiment, the trash box assembly 40 includes a trash box 41, a guiding portion 42 and a scraping strip 43 connected in sequence. The trash box 41 is disposed on the movable bracket 30. The guiding portion 42 is disposed between the trash box 41 and the cleaning roller 20 and extends along the direction towards the cleaning surface. The scraping strip 43 is disposed at one end of the guiding portion 42 away from the trash box 41, and the scraping strip 43 is used to contact the cleaning surface.

[0045] Among them, the cleaning device 100 includes a first state, a moving state and a second state. As Figure 1As shown, the cleaning device 100 is in the first state. When the cleaning device 100 is in the first state, the movable bracket 30 is provided on the bottom surface of the housing 10 and the movable bracket 30 abuts against the bottom surface of the housing 10. As Figure 2 and Figure 3 shown, the cleaning device 100 is in the second state. When the cleaning device 100 is in the second state, the movable bracket 30 is spaced from the bottom surface of the housing 10, and the trash bin assembly 40 or the movable bracket 30 abuts against the back surface of the housing 10. When the cleaning device 100 is in the moving state, the trash bin assembly 40 and the movable bracket 30 reciprocally move along the first direction D1. When the trash bin assembly 40 and the movable bracket 30 move along the first direction D1, the size of the inlet passage between the scraping bar 43 of the trash bin assembly 40 and the cleaning roller 20 increases, and the scraping bar 43 of the trash bin 41 moves upward in the vertical direction. When the trash bin assembly 40 and the movable bracket 30 move in the opposite direction of the first direction D1, the size of the inlet passage between the scraping bar 43 of the trash bin assembly 40 and the cleaning roller 20 decreases, and the scraping bar 43 of the trash bin 41 moves downward in the vertical direction. It should be noted that the cleaning device 100 may further include multiple states between the first state and the second state, that is, the trash bin assembly 40 and the movable bracket 30 of the cleaning device 100 may stop moving in any state when moving along the first direction D1 and its opposite direction, and the present application does not limit this. For the convenience of subsequent description, the opposite direction of the first direction D1 is named the second direction D2, which should not be construed as a limitation of the present application.

[0046] Further, the scraping bar 43 of the garbage box assembly 40 abuts against the cleaning surface. When the cleaning device 100 is in the cleaning process and there is a relatively large particle of garbage caught between the cleaning roller 20 and the scraping bar 43, the rotation of the cleaning roller 20 causes the garbage to squeeze the scraping bar 43 of the garbage box assembly 40. The scraping bar 43 of the garbage box assembly 40 will be subjected to a thrust force and move backward by extrusion, so that the garbage box assembly 40 drives the movable bracket 30 to move along the first direction D1 and increases the size of the inlet channel between the scraping bar 43 and the cleaning roller 20, so that relatively large particles of garbage can enter the garbage box 41 from the inlet channel for collection, improving the garbage recovery rate of the cleaning device 100. Similarly, when the cleaning device 100 encounters a step, a bump or an obstacle on the cleaning path, the scraping bar 43 of the garbage box assembly 40 will be subjected to a thrust force and move backward by extrusion, so that the garbage box assembly 40 drives the movable bracket 30 to move along the first direction D1. The first direction D1 forms an angle with the cleaning surface. In other words, the scraping bar 43 of the garbage box assembly 40 will move upward in the vertical direction, so that the scraping bar 43 can cross obstacles such as steps and bumps, improving the overstep ability of the cleaning device 100 and not damaging the cleaning surface.

[0047] Further, in the present embodiment, the angle α between the first direction D1 and the cleaning surface is 20°. Optionally, in other embodiments, the range of the angle α between the first direction D1 and the cleaning surface is: 0° < α < 90°. For example, in other embodiments, the angle α between the first direction D1 and the cleaning surface may also be 10°, or 20°, or 30°, or 40°, or 50°, or 60°, or 70°, or 80°, or other values within 0° - 90°. The present application does not limit this.

[0048] Among them, the scraping strip 43 is a flexible member, and the material of the scraping strip 43 includes but is not limited to soft rubber. The scraping strip 43 can be used to adapt to cleaning surfaces of different heights according to its own deformation amount, so that the scraping strip 43 is kept in close contact with the cleaning surface. In addition, in order to make the scraping strip 43 fit the cleaning surface better, there is a preload between the scraping strip 43 and the cleaning surface. It can be understood that there is a preload between the scraping strip 43 and the cleaning surface, that is, there is a certain pre-applied pressure or force between the scraping strip 43 and the cleaning surface to ensure close contact or fixation between the scraping strip 43 and the cleaning surface. It can be understood that when the cleaning device 100 is in the first state, the pre-pressure between the scraping strip 43 and the cleaning surface is relatively large. When the cleaning device 100 is in the moving state or the second state, the scraping strip 43 has moved a certain distance along the first direction D1, and the pre-pressure between the scraping strip 43 and the cleaning surface decreases to reduce the friction between the scraping strip 43 and the cleaning surface, and there is even a certain gap from the cleaning surface to facilitate the cleaning device 100 to cross a step.

[0049] Among them, the guiding part 42 is a rigid member, and the guiding part 42 provides rigid support for the scraping strip 43 so that there can be a pre-pressure between the scraping strip 43 and the cleaning surface. When the cleaning device 100 switches between the first state and the second state, the scraping strip 43 is a flexible member and can fit the cleaning surface well. The guiding part 42 is a rigid member, which can avoid problems such as bending of the guiding part 42 when the cleaning device 100 crosses a step or encounters a large obstacle, so as to ensure that the scraping strip 43 can fit the cleaning surface well, which is beneficial to improving the cleaning performance of the cleaning device 100. And, the guiding part 42 is a bent structure, and the guiding part 42 is a concave structure, which is beneficial to guiding the garbage to avoid the garbage falling out of the introduction channel. Optionally, the guiding part 42 includes but is not limited to materials such as plastic and metal.

[0050] Further, one end of the guiding portion 42 away from the trash box 41 has a mounting portion for mounting the scraping bar 43. Optionally, in this embodiment, the scraping bar 43 is assembled on the guiding portion 42 by being inserted from the side. The guiding portion 42 and the trash box 41 are of an integral structure. In other words, the guiding portion 42 and the trash box 41 are integrally formed by one process. Or the guiding portion 42 and the trash box 41 may be of a split structure and are fixed by a connection method, and the connection is not limited to fixing methods such as screws or buckles. For the convenience of description in this application, they are distinguished and named, which should not be construed as a limitation to this application. In other embodiments, the scraping bar 43 may also be fixed on the guiding portion 42 by means such as screw fixation, or the trash box 41, the guiding portion 42 and the scraping bar 43 are formed by injection molding once or multiple times, and this application does not limit this.

[0051] In the cleaning device 100 provided by the present application, the cleaning roller 20 is disposed in the receiving cavity of the housing 10 and is rotatably connected to the housing 10. The movable bracket 30 is slidably connected to the housing 10 and can reciprocally move relative to the housing 10 along the first direction D1. The trash box assembly 40 is disposed on the movable bracket 30 and on the side of the movable bracket 30 facing the cleaning roller 20. The trash box assembly 40 can drive the movable bracket 30 to reciprocally move along the first direction D1. Among them, an included angle is formed between the first direction D1 and the cleaning surface. The scraping strip 43 of the trash box assembly 40 abuts against the cleaning surface. When the cleaning device 100 is in the cleaning process and there is relatively large particulate trash clamped between the cleaning roller 20 and the scraping strip 43 or the guiding portion 42 of the trash box assembly 40, the rotation of the cleaning roller 20 causes the trash to squeeze the scraping strip 43 or the guiding portion 42 of the trash box assembly 40. The scraping strip 43 or the guiding portion 42 of the trash box assembly 40 will be subjected to a thrust force and be squeezed and moved backward, so that the trash box assembly 40 drives the movable bracket 30 to move along the first direction D1 and makes the size of the inlet channel between the scraping strip 43 and the cleaning roller 20 increase, so that relatively large particulate trash can enter the trash box 41 from the inlet channel and be collected, thereby improving the trash recovery rate of the cleaning device 100. Moreover, when the cleaning device 100 encounters a step, a bump or an obstacle on the cleaning path, the scraping strip 43 of the trash box assembly 40 will be subjected to a thrust force and be squeezed and moved backward, so that the trash box assembly 40 drives the movable bracket 30 to move along the first direction D1. An included angle is formed between the first direction D1 and the cleaning surface. In other words, the scraping strip 43 of the trash box assembly 40 will move upward in the vertical direction, so that the scraping strip 43 can cross obstacles such as steps and protrusions, improving the overstep ability of the cleaning device 100 and not damaging the cleaning surface.

[0052] Moreover, in this embodiment, please refer to Figure 6 , Figure 6 which is a schematic structural diagram of a trash box disposed on a movable bracket provided by an embodiment of the present application. The trash box assembly 40 is disposed on the movable bracket 30 and is a split structure with the movable bracket 30, which is convenient for the user to directly take out the trash box assembly 40 from the cleaning device 100, facilitating the user to remove the trash in the trash box assembly 40 or perform operations such as disassembling the cleaning device 100.

[0053] Please refer to Figures 1 to 7 , Figure 7 which is a schematic cross-sectional structure of a cleaning device in a first state provided by an embodiment of the present application Figure 2. In one embodiment, the cleaning device 100 further includes an elastic member 50. The elastic member 50 is disposed on a side of the movable bracket 30 facing away from the cleaning roller 20, and the elastic member 50 is respectively connected to the movable bracket 30 and the housing 10.

[0054] Specifically, the elastic member 50 is respectively connected to a side of the movable bracket 30 facing away from the cleaning roller 20 and a side of the housing 10 facing the cleaning roller 20. The elastic member 50 has elastic potential energy, and the elastic member 50 can be used to apply a force to the movable bracket 30 along the second direction D2, so that the movable bracket 30 can drive the trash box assembly 40 to move along the second direction D2. That is, when the cleaning device 100 crosses a threshold or accommodates larger garbage particles, the trash box assembly 40 will push the movable bracket 30 to move along the first direction D1, the elastic member 50 contracts and increases its elastic potential energy. When the cleaning device 100 crosses the threshold or the larger garbage particles have passed through the introduction channel, the elastic member 50 resumes its deformation while pushing the movable bracket 30 and the trash box assembly 40 to move along the second direction D2 for resetting, so that the pre-pressure between the scraping strip 43 and the cleaning surface is restored and the cleaning surface is cleaned.

[0055] In one embodiment, a blocking portion 14 is further provided on the bottom surface of the housing 10. The blocking portion 14 is disposed on a side of the housing 10 facing away from the cleaning surface. The blocking portion 14 can be used to abut against and block the excessive movement of the movable bracket 30 along the second direction D2, to prevent the movable bracket 30 from detaching from the housing 10 along the second direction D2.

[0056] Optionally, in this embodiment, the elastic member 50 is a cylindrical spring. In other embodiments, the elastic member 50 can also be a torsion spring, a leaf spring, a tower spring or other elastic structural members. The present application does not limit this. Further optionally, in this embodiment, the number of the elastic members 50 is 3, and the 3 elastic members 50 are respectively arranged at intervals on a side of the movable bracket 30 facing away from the cleaning roller 20. The number of the elastic members 50 being 3 can improve the reset speed of the movable bracket 30, and thus improve the cleaning efficiency of the cleaning device 100. In other embodiments, the number of the elastic members 50 can also be 1, or 2, or 4, or more than 4. The present application does not limit this.

[0057] In this application, the elastic member 50 is exemplified as a cylindrical spring, which should not be construed as a limitation to this application. The elastic member 50 is a cylindrical spring. The housing 10 is provided with a receiving groove 11 extending along the first direction D1 on the back surface facing the movable bracket 30, and the receiving groove 11 is used to receive the elastic member 50. The movable bracket 30 is provided with a fixing portion 31 extending along the first direction D1 on the side facing the back surface of the housing 10, and the fixing portion 31 is used to fix the elastic member 50.

[0058] Specifically, one end of the elastic member 50 abuts against the fixing portion 31, and one end abuts against the bottom wall of the receiving groove 11. Moreover, the elastic member 50 surrounds at least part of the outer periphery of the fixing portion 31 to limit the elastic member 50 on the fixing portion 31.

[0059] Furthermore, in one embodiment, the shape of the fixing portion 31 corresponds to the shape of the receiving groove 11. In other words, when the trash bin assembly 40 and the movable bracket 30 move along the first direction D1, the fixing portion 31 moves along the first direction D1 to compress the elastic member 50 into the receiving groove 11. The receiving groove 11 can be used to guide the movement of the fixing portion 31, avoiding phenomena such as dislocation during the movement of the movable bracket 30, and improving the accuracy and stability of the movement of the movable bracket 30 and the trash bin assembly 40.

[0060] Please refer to Figure 1 and Figure 8 , Figure 8 which is a partial cross-sectional structural schematic diagram of a cleaning device provided by an embodiment of this application. In one embodiment, the movable bracket 30 is provided with a slider 32 on the side facing the side surface of the housing 10, and the housing 10 is provided with a sliding groove 12 on the side facing the movable bracket 30. The sliding groove 12 extends along the first direction D1. The slider 32 is arranged in the sliding groove 12 and can reciprocally move relative to the sliding groove 12 along the first direction D1, so that the movable bracket 30 reciprocally moves relative to the housing 10 along the first direction D1.

[0061] Specifically, the movable bracket 30 has a first side face and a second side face facing the side face of the housing 10. The first side face and the second side face are arranged back to back, and sliders 32 are provided on both the first side face and the second side face. Similarly, the housing 10 also has a third side face and a fourth side face. The third side face and the fourth side face of the housing 10 are arranged back to back, and sliding grooves 12 are provided on both the third side face and the fourth side face. The first side face corresponds to the third side face, and the slider 32 on the first side face is arranged in the sliding groove 12 on the third side face. The second side face corresponds to the fourth side face, and the slider 32 on the second side face is arranged in the sliding groove 12 on the fourth side face. Thus, both ends of the movable bracket 30 are slidably connected to the housing 10, so as to improve the sliding stability of the movable bracket 30 and prevent the movable bracket 30 from detaching from the housing 10.

[0062] It should be noted that when there are multiple pairs of sliding pairs formed by the sliding grooves 12 and the sliders 32, each pair is parallel to each other, so that the movable bracket 30 can slide effectively relative to the housing 10. Specifically, if there are multiple sliding grooves 12 on the third side face and the fourth side face of the housing 10, the multiple sliding grooves 12 are parallel to each other, and the sliding grooves 12 on the third side face and the sliding grooves 12 on the fourth side face are also parallel to each other. Optionally, in this embodiment, there are two pairs of sliding pairs formed by the slider 32 on the first side face and the sliding groove 12 on the third side face, and two pairs of sliding pairs formed by the slider 32 on the second side face and the sliding groove 12 on the fourth side face. In other embodiments, the number of sliding pairs formed by the slider 32 on the first side face and the sliding groove 12 on the third side face can be one pair, or three pairs, or four pairs, or more than four pairs, and the number of sliding pairs formed by the slider 32 on the second side face and the sliding groove 12 on the fourth side face can be one pair, or three pairs, or four pairs, or more than four pairs. The present application does not limit this.

[0063] Optionally, the slider 32 includes, but is not limited to, structural members such as protrusions, shafts, rollers, etc. that slide within the chute 12. Further optionally, the slider 32 can be an integral structure with the movable bracket 30, or the slider 32 can be assembled onto the movable bracket 30, and this application does not limit this. Specifically, when the slider 32 is a protrusion structure, the slider 32 can be an integral structure with the movable bracket 30. When the slider 32 is a shaft, the slider 32 can be fixed to the movable bracket 30 by means of screws, and the slider 32 on the first side and the slider 32 on the third side can be the same shaft, and the material of the shaft can be materials such as plastic, metal, etc. When the slider 32 is a roller, the roller can be a bearing or other rolling connectors. Similarly, the slider 32 on the first side and the slider 32 on the third side can be the same rolling connectors.

[0064] Optionally, the chute 12 can be an integral structure with the housing 10, or the chute 12 can be combined with the housing 10 through other parts, and the combination method can be snap - fit fixation, threaded connection fixation, etc., and this application does not limit this.

[0065] In one implementation, it can also be that a chute is provided on one side of the movable bracket 30 facing the side of the housing 10, and a slider is provided on the side of the housing 10 facing the movable bracket 30. The chute extends along the first direction D1, and the slider is disposed within the chute and can reciprocally move relative to the chute along the first direction D1, so that the movable bracket 30 reciprocally moves relative to the housing 10 along the first direction D1. In this implementation, the structures of the slider and the chute are the same as those described above, and this application will not repeat them here and should not be construed as a limitation of this application.

[0066] Please refer to Figure 5 and Figure 7 , in one implementation, a limiting portion 13 is provided on the top surface of the housing 10 facing the movable bracket 30. The limiting portion 13 has a limiting surface facing the movable bracket 30, and the limiting surface extends along the first direction D1. The limiting surface is used to abut against the trash box assembly 40 so that the trash box assembly 40 reciprocally moves along the first direction D1.

[0067] A limiting portion 13 is provided on the top surface of the housing 10. The limiting portion 13 is used to abut against the trash box assembly 40 to limit the trash box assembly 40 and the movable bracket 30 on the housing 10, and prevent the trash box assembly 40 and the movable bracket 30 from being misaligned relative to the housing 10.

[0068] Furthermore, the limiting portion 13 has a limiting surface for abutting against the trash box 41, and the limiting surface extends obliquely along the first direction D1. In other words, the trash box assembly 40 can move along the limiting surface along the first direction D1. The limiting surface can be used to limit the movement of the trash box assembly 40 along the first direction D1, so as to avoid the trash box assembly 40 and the movable bracket 30 from moving when they move.

[0069] Furthermore, the garbage box 41 has a matching portion 411 on one side close to the limiting portion 13, and the matching portion 411 has a matching surface on the side facing the limiting portion 13, and the matching surface is parallel to the limiting surface, and the matching surface cooperates with the limiting surface to improve the smoothness of the garbage box assembly 40 when sliding relative to the limiting portion 13.

[0070] In one embodiment, the cleaning device 100 also includes a brush roller 60, which is disposed in the accommodating cavity and rotatably connected to the shell 10, and the brush roller 60 is disposed on the side of the garbage box assembly 40 away from the cleaning surface, and the brush roller 60 is used to sweep the garbage on the cleaning roller 20 to the garbage box assembly 40.

[0071] Specifically, the brush roller 60 is disposed above the trash box 41. The brush roller 60 abuts against the cleaning roller 20 when rotating, and is used to brush away the trash adhered to the outer surface of the cleaning roller 20 into the trash box 41. Specifically, after the cleaning roller 20 cleans the cleaning surface, larger trash such as hair may adhere to the surface of the cleaning roller 20. The brush roller 60 abuts against the cleaning roller 20 when rotating and brushes away the larger trash such as hair into the trash box 41, thereby preventing the trash on the cleaning roller 20 from continuing to adhere to the cleaning roller 20, and improving the trash collection efficiency of the cleaning device 100.

[0072] The present application also provides a cleaning machine, which includes a device body and the cleaning device 100, wherein the cleaning device 100 is arranged on the device body.

[0073] 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.

[0074] In the cleaning machine provided by the present application, the cleaning roller 20 is disposed in the receiving cavity of the housing 10 and is rotatably connected to the housing 10. The movable bracket 30 is slidably connected to the housing 10 and can reciprocate relative to the housing 10 along the first direction D1. The trash bin assembly 40 is disposed on the movable bracket 30 and on the side of the movable bracket 30 facing the cleaning roller 20. The trash bin assembly 40 can drive the movable bracket 30 to reciprocate along the first direction D1. Among them, there is an included angle between the first direction D1 and the cleaning surface. The scraping bar 43 of the trash bin assembly 40 abuts against the cleaning surface. When the cleaning machine is in the cleaning process and there is relatively large particulate waste sandwiched between the cleaning roller 20 and the scraping bar 43 or the guiding portion 42 of the trash bin assembly 40, the rotation of the cleaning roller 20 squeezes the waste against the scraping bar 43 or the guiding portion 42 of the trash bin assembly 40. The scraping bar 43 or the guiding portion 42 of the trash bin assembly 40 will be subjected to a thrust force and be squeezed and moved backward, so that the trash bin assembly 40 drives the movable bracket 30 to move along the first direction D1 and increases the size of the inlet channel between the scraping bar 43 and the cleaning roller 20, so that relatively large particulate waste can enter the trash bin 41 from the inlet channel and be collected, thereby improving the waste recovery rate of the cleaning machine. And when the cleaning machine encounters steps, bumps or obstacles on the cleaning path, the scraping bar 43 of the trash bin assembly 40 will be subjected to a thrust force and be squeezed and moved backward, so that the trash bin assembly 40 drives the movable bracket 30 to move along the first direction D1. There is an included angle between the first direction D1 and the cleaning surface. In other words, the scraping bar 43 of the trash bin assembly 40 will move upward in the vertical direction, so that the scraping bar 43 can cross obstacles such as steps and protrusions, improving the overstep ability of the cleaning machine and not damaging the cleaning surface.
