Abstract

The application provides a cleaning device and a cleaning machine. The cleaning device comprises a shell, a cleaning roller, a garbage box assembly, an auxiliary roller and a linkage assembly. The cleaning roller and the auxiliary roller are arranged in an accommodation space formed by the shell. The cleaning roller is rotatably connected to the shell and is used for cleaning a surface to be cleaned. The garbage box assembly is connected to the shell. The auxiliary roller is rotatably connected to the shell. The auxiliary roller abuts against the cleaning roller when rotating and brushes off garbage adhered to the outer surface of the cleaning roller to the garbage box. The linkage assembly is arranged on the side surface of the shell and is connected to the cleaning roller and the auxiliary roller, so that the cleaning roller drives the auxiliary roller to rotate when the cleaning roller rotates. The linkage assembly forms a linkage mechanism for the cleaning roller and the auxiliary roller, so that the cleaning roller and the auxiliary roller always maintain stable contact pressure and friction frequency, which can ensure the timeliness and effectiveness of self-cleaning of the cleaning device. In addition, a power source does not need to be designed for the auxiliary roller separately, which can simplify the internal structure of the cleaning device and reduce the cost of the cleaning device.

Description

Technical Field

[0001] This application relates to the field of cleaning device technology, specifically to a cleaning device and cleaning machine. Background Technology

[0002] Most current cleaning devices use a design that combines a cleaning roller with an auxiliary roller. The cleaning roller rotates to clean the surface to be cleaned, while the auxiliary roller brushes away surface debris.

[0003] In related technologies, the auxiliary roller requires a separate motor, but its rotation speed is difficult to match with that of the cleaning roller. If the speed is too low, the debris will not be cleaned thoroughly, while if it is too high, it will aggravate the wear and tear on both rollers, still requiring frequent manual cleaning. Furthermore, the additional motor required to drive the auxiliary roller increases the number of parts and the assembly difficulty, thereby increasing the manufacturing and maintenance costs of the cleaning device. Utility Model Content

Both ends of a waste container assembly are rotatably connected to the outer walls of the housing, forming a receiving space that connects to the receiving space. An auxiliary roller is disposed within the receiving space, rotatably connected to the housing. When rotating, the auxiliary roller abuts against the cleaning roller, brushing away debris adhering to the outer surface of the cleaning roller into the receiving space of the waste container. A linkage assembly is disposed on the side of the housing, connecting the cleaning roller and the auxiliary roller respectively, so that the rotation of the cleaning roller simultaneously drives the rotation of the auxiliary roller.

The cleaning device also includes a first elastic element located within the receiving hole. One end of the first elastic element is connected to the fixing component, and the other end is connected to the positioning fitting. The positioning fitting slides relative to the fixing component along a first direction to separate the positioning fitting from the first positioning groove. The first elastic element is in a compressed state. The compressed first elastic element enables the positioning fitting to slide along a second direction opposite to the first direction to engage with the first positioning groove.

The button assembly slides relative to the second side plate along a second direction to separate the button assembly from the second side plate, and the second elastic member is in a compressed state; the second elastic member in the compressed state enables the button assembly to slide along a first direction opposite to the second direction to engage the button assembly within the second side plate.

[0015] Secondly, this application provides a cleaning machine, which includes a handle and the cleaning device, wherein the handle is connected to one end of the cleaning device away from the cleaning roller.

[0016] In the cleaning machine provided in this application, a housing encloses a receiving space. A cleaning roller is disposed within the receiving space, rotatably connected to the housing, and used to clean the surface to be cleaned. Both ends of a waste container assembly are rotatably connected to the outer walls of the housing, forming a receiving space that connects to the receiving space. An auxiliary roller is disposed within the receiving space, rotatably connected to the housing. When rotating, the auxiliary roller abuts against the cleaning roller, brushing away debris adhering to the outer surface of the cleaning roller into the receiving space of the waste container. A linkage assembly is disposed on the side of the housing, connecting the cleaning roller and the auxiliary roller respectively, so that the rotation of the cleaning roller simultaneously drives the rotation of the auxiliary roller. The linkage assembly creates a linkage mechanism between the cleaning roller and the auxiliary roller, ensuring that they maintain stable contact pressure and friction frequency, guaranteeing the timeliness and effectiveness of the cleaning machine's self-cleaning. Furthermore, it eliminates the need for a separate power source for the auxiliary roller, simplifying the internal structure of the cleaning machine and reducing its cost.

[0023] Most current cleaning devices use a design that combines a cleaning roller with an auxiliary roller. The cleaning roller rotates to clean the surface to be cleaned, while the auxiliary roller brushes away surface debris.

[0024] In related technologies, the auxiliary roller requires a separate motor, but its rotation speed is difficult to match with that of the cleaning roller. If the speed is too low, the debris will not be cleaned thoroughly, while if it is too high, it will aggravate the wear and tear on both rollers, still requiring frequent manual cleaning. Furthermore, the additional motor required to drive the auxiliary roller increases the number of parts and the assembly difficulty, thereby increasing the manufacturing and maintenance costs of the cleaning device.

[0025] Please refer to Figures 1 to 3 , Figure 1 This is a schematic diagram of the structure of a cleaning machine provided in an embodiment of this application. Figure 2 This is a schematic cross-sectional view of a cleaning device provided in an embodiment of this application. Figure 1 , Figure 3 This is a schematic diagram of the structure of a cleaning device including a linkage component provided in an embodiment of this application.

[0026] This application provides a cleaning device and a cleaning machine 1000 to solve the technical problem in the related art that the auxiliary roller needs to be equipped with a separate motor, but its speed is difficult to match with the cleaning roller, and it is easy to increase the manufacturing cost and maintenance cost of the cleaning device.

[0027] This application provides a cleaning device 100 for cleaning dust, dirt, impurities, and other substances from a surface to be cleaned. The surface to be cleaned includes, but is not limited to, tabletops, floors, or other surfaces that can be cleaned.

[0028] The cleaning device 100 includes a housing 10, a cleaning roller 20, a waste container assembly 30, an auxiliary roller 40, and a linkage assembly 50. The housing 10 encloses a receiving space. The cleaning roller 20 is disposed within the receiving space, rotatably connected to the housing 10, and used to clean surfaces to be cleaned. The two ends of the waste container assembly 30 are rotatably connected to the outer walls of the housing 10, and the waste container assembly 30 encloses a receiving space that communicates with the receiving space. The auxiliary roller 40 is disposed within the receiving space, rotatably connected to the housing 10, and when rotating, it abuts against the cleaning roller 20, brushing away debris adhering to the outer surface of the cleaning roller 20 into the receiving space of the waste container. The linkage assembly 50 is disposed on the side of the housing 10, and connects the cleaning roller 20 and the auxiliary roller 40 respectively, so that the rotation of the cleaning roller 20 simultaneously drives the rotation of the auxiliary roller 40.

[0029] It is understood that the cleaning device 100 in this application embodiment can be, but is not limited to, a floor cleaning tool such as a cleaning machine 1000, a sweeping robot, or a floor scrubber.

[0030] The cleaning device 100 of this embodiment includes the housing 10, which encloses a receiving space. The receiving space can be used to receive the cleaning roller 20, the auxiliary roller 40 and other structural components of the cleaning device 100. This application does not limit this.

[0031] The cleaning device 100 of this embodiment further includes a cleaning roller 20, which is capable of rotating and cleaning the surface to be cleaned. Specifically, the cleaning roller 20 is capable of rotating along its own axis, and the outer periphery of the cleaning roller 20 is made of a flexible material, capable of adsorbing fine dust, impurities, and other substances. The cleaning roller 20 rubs against the surface to be cleaned to adsorb dust, dirt, impurities, and other substances on the surface to be cleaned onto the cleaning roller 20, thereby achieving the purpose of cleaning the surface to be cleaned.

[0032] The cleaning device 100 of this embodiment also includes the garbage box assembly 30. The garbage box assembly 30 includes a garbage shovel bar. The garbage shovel bar and the cleaning roller 20 are spaced apart to form a garbage inlet channel. The garbage shovel bar is used to contact the surface to be cleaned and shovel the garbage into the inlet channel. The inlet channel is used to guide the garbage into the interior of the cleaning device 100 and collect it through the garbage box assembly 30.

[0033] Furthermore, the cleaning assembly also includes an auxiliary roller 40, which is disposed inside the housing 10 and rotatably connected to the housing 10. The auxiliary roller 40 is located on the side of the trash box assembly 30 away from the surface to be cleaned, and is used to sweep the trash on the cleaning roller 20 onto the trash box assembly 30.

[0034] Specifically, the auxiliary roller 40 is positioned above the waste container assembly 30. When rotating, the auxiliary roller 40 abuts against the cleaning roller 20 and brushes away any debris adhering to the outer surface of the cleaning roller 20 into the waste container assembly 30. Specifically, after the cleaning roller 20 has cleaned the surface to be cleaned, larger debris such as hair may remain on its surface. When the auxiliary roller 40 rotates, it abuts against the cleaning roller 20 and brushes away this larger debris into the waste container assembly 30, preventing further adhesion of debris to the cleaning roller 20 and improving the waste collection efficiency of the cleaning device 100.

[0035] The cleaning device 100 of this embodiment also includes a trash box assembly 30, which serves as a temporary storage space for trash inside the cleaning device 100. During the cleaning process, it continuously receives the trash cleaned out by the cleaning components, enabling the cleaning device 100 to continue cleaning without affecting the cleaning effect due to a lack of storage space for trash.

[0036] The linkage component 50 is located on the side of the housing 10. The linkage component 50 is connected to the rotating shafts of the cleaning roller 20 and the auxiliary roller 40 respectively, so that when the cleaning roller 20 rotates, the auxiliary roller 40 is synchronously driven to rotate through the connection structure.

[0037] It should be noted that in this embodiment, the cleaning machine 1000 is a manual cleaning machine. The user pushes the cleaning device 100 of the cleaning machine 1000 forward and cleans the surface to be cleaned. The cleaning roller 20 contacts the surface to be cleaned and rotates passively. While the cleaning roller 20 is rotating, it drives the auxiliary roller 40 to rotate, so as to sweep the garbage of the cleaning roller 20 into the garbage box assembly 30 for collection.

[0038] In another embodiment, the cleaning roller 20 may also have a built-in rotary motor that directly drives the cleaning roller 20 to rotate actively. Simultaneously, the rotation of the cleaning roller 20 drives the auxiliary roller 40 to rotate, thereby sweeping the debris from the cleaning roller 20 into the waste box assembly 30 for collection. In summary, this application does not limit whether the cleaning roller 20 rotates actively or passively, and this should not be construed as a limitation of this application.

[0039] The linkage component 50 is installed on the side of the housing 10 and connects the rotating shafts of the cleaning roller 20 and the auxiliary roller 40 respectively. When the cleaning roller 20 rotates (whether driven by an active motor or by passive friction), the linkage component 50 synchronously transmits the rotational power to the auxiliary roller 40, so that the two maintain coordinated rotation in the same or opposite directions.

[0040] The linkage component 50 establishes a linkage mechanism between the cleaning roller 20 and the auxiliary roller 40, ensuring the timeliness and effectiveness of self-cleaning. The core function of the auxiliary roller 40 is to brush away debris from the surface of the cleaning roller 20, and its cleaning effect depends entirely on its relative movement with the cleaning roller 20. The linkage component 50 ensures that the auxiliary roller 40 rotates at the same speed (or in a fixed ratio) as the cleaning roller 20, maintaining stable contact pressure and friction frequency. For example, if the cleaning roller 20 rotates quickly, the auxiliary roller 40 also accelerates synchronously, quickly brushing away a large amount of adhering debris. If the cleaning roller 20 rotates slowly due to manual pushing, the auxiliary roller 40 also slows down accordingly, preventing the auxiliary roller 40 from brushing too fast and wearing down the cleaning roller 20 due to mismatched speeds, or brushing too slowly and resulting in incomplete cleaning.

[0041] Furthermore, the linkage component 50 enables the cleaning roller 20 and the auxiliary roller 40 to form a linkage mechanism, which also simplifies the internal structure of the cleaning device 100 and reduces its cost. Specifically, the auxiliary roller 40 and the cleaning roller 20 rotate synchronously through the linkage component 50, eliminating the need for a separate power source (such as an additional motor) for the auxiliary roller 40; the linkage component 50 can simply utilize the power of the cleaning roller 20.

[0042] Furthermore, the linkage component 50 enables the cleaning roller 20 and the auxiliary roller 40 to form a linkage mechanism, which can adapt to various driving methods and improve the versatility of the equipment. Regardless of whether the cleaning roller 20 is driven by an active motor or passively pushed manually, the linkage component 50 can adaptively transmit power. When driven by a motor, the auxiliary roller 40 rotates faster when the power is strong; when pushed manually, the auxiliary roller 40 rotates slower when the power is weak, always matching the working state of the cleaning roller 20.

[0043] In the cleaning device 100 provided in this application, the housing 10 encloses a receiving space. A cleaning roller 20 is disposed within the receiving space, rotatably connected to the housing 10, and used to clean surfaces to be cleaned. Both ends of a trash can assembly 30 are rotatably connected to the outer walls of the housing 10, and the trash can assembly 30 encloses a receiving space that communicates with the receiving space. An auxiliary roller 40 is disposed within the receiving space, rotatably connected to the housing 10, and when rotating, the auxiliary roller 40 abuts against the cleaning roller 20, brushing away trash adhering to the outer surface of the cleaning roller 20 into the receiving space of the trash can. A linkage assembly 50 is disposed on the side of the housing 10, connecting the cleaning roller 20 and the auxiliary roller 40 respectively, so that the rotation of the cleaning roller 20 simultaneously drives the rotation of the auxiliary roller 40. The linkage component 50 enables the cleaning roller 20 and the auxiliary roller 40 to form a linkage mechanism, so that the cleaning roller 20 and the auxiliary roller 40 always maintain a stable contact pressure and friction frequency, which can ensure the timeliness and effectiveness of the self-cleaning of the cleaning device 100. Furthermore, there is no need to design a separate power source for the auxiliary roller 40, which can simplify the internal structure of the cleaning device 100 and reduce the cost of the cleaning device 100.

[0044] Please refer to Figures 1 to 10 , Figure 4 This is a schematic cross-sectional view of a cleaning device 100 provided in an embodiment of this application. Figure 2 , Figure 5 yes Figure 4 Enlarged diagram of the middle section Figure 1 , Figure 6 yes Figure 4 Enlarged diagram of the middle section Figure 2 , Figure 7 This is a schematic diagram of the structure of a linkage component provided in an embodiment of this application. Figure 8 This is a schematic cross-sectional view of a cleaning device 100 provided in an embodiment of this application.

[0045] In one embodiment, the linkage assembly 50 includes a first rotating member 51, a second rotating member 52, and a transmission member 53. The first rotating member 51 and the second rotating member 52 are spaced apart. The first rotating member 51 is connected to the cleaning roller 20, and the second rotating member 52 is connected to the auxiliary roller 40. The transmission member 53 is connected to the first rotating member 51 and the second rotating member 52 respectively. When the cleaning roller 20 rotates, it drives the first rotating member 51 to rotate, and the transmission member 53 drives the second rotating member 52 and the auxiliary roller 40 to rotate.

[0046] Specifically, the power input end of the first rotating component 51 is directly and fixedly connected to the rotating shaft of the cleaning roller 20. When the cleaning roller 20 rotates, it directly drives the first rotating component 51 to rotate synchronously. The second rotating component 52 is the power output end, directly and fixedly connected to the rotating shaft of the auxiliary roller 40. When the second rotating component 52 is driven to rotate, it directly drives the auxiliary roller 40 to rotate synchronously. The transmission component 53 can be understood as a power bridge, which is an intermediate component connecting the first rotating component 51 and the second rotating component 52. The transmission component 53 includes, but is not limited to, chains, belts, transmission gears, connecting rods, etc. The transmission component 53 can stably transmit the rotational motion of the first rotating component 51 to the second rotating component 52, ensuring that the power is uninterrupted and does not deviate.

[0047] The rigid connection between the first rotating component 51, the second rotating component 52, and the transmission component 53 ensures that the power transmission is delayed and slip-free, so that the rotation of the cleaning roller 20 and the auxiliary roller 40 always remains fixedly connected. When the cleaning roller 20 rotates fast, the auxiliary roller 40 also rotates faster in sync; when the cleaning roller 20 decelerates, the auxiliary roller 40 also decelerates accordingly, thereby stabilizing the contact pressure and friction frequency between the two and ensuring the effective removal of garbage.

[0048] Furthermore, the cleaning roller 20 and the auxiliary roller 40 rotate synchronously through the linkage component 50, eliminating the need for additional motors or complex control modules. Power transmission is achieved solely through the rigid connection of mechanical components, resulting in fewer parts and a lower failure rate. This simplifies the internal structure of the device and reduces manufacturing costs.

[0049] In one embodiment, the outer periphery of the first rotating member 51 is provided with a first tooth, the outer periphery of the second rotating member 52 is provided with a second tooth, the transmission member 53 is a rack and the inner side of the transmission member 53 is provided with a third tooth, the third tooth meshing with the first tooth and the second tooth respectively.

[0050] It should be noted that the teeth are rigidly interlocked, which ensures that the rotation speed of the cleaning roller 20 and the auxiliary roller 40 remains constant, ensuring stable contact pressure and friction frequency between the two, and more thorough removal of debris.

[0051] Please refer to Figures 1 to 10 In one embodiment, the housing 10 includes a first side plate 11, and the linkage component 50 is disposed on the side of the first side plate 11 opposite to the cleaning roller 20. The first side plate 11 is provided with a first through hole and a second through hole. The first rotating member 51 includes a first annular protrusion 511, which passes through the first through hole and is connected to the cleaning roller 20. The second rotating member 52 includes a second annular protrusion 521, which passes through the second through hole and is connected to the auxiliary roller 40.

[0052] The first side plate 11 is a baffle on the side of the housing 10, serving as the mounting base for the linkage component 50, and also separating the internal receiving space of the housing 10 (where the cleaning roller 20 and the auxiliary roller 40 are located) from the external space (where the linkage component 50 is located).

[0053] The linkage component 50 is located on the side of the first side plate 11 opposite to the cleaning roller 20 (i.e., the outer side of the side plate, in the opposite direction to the internal receiving space). This ensures that the linkage component 50 does not occupy the internal receiving space of the housing 10, thus avoiding interference with internal components such as the cleaning roller 20 and the auxiliary roller 40.

[0054] Furthermore, the first side plate 11 serves as a separator, which can reduce the direct contact between internal debris and dust and the external linkage component 50 during the cleaning process, prevent the teeth from being blocked by debris, and extend the service life of the linkage component 50.

[0055] Furthermore, the linkage component 50 is on the outside, while the cleaning roller 20 and the auxiliary roller 40 are on the inside. The two are connected by the first through hole, the second through hole, the first annular protrusion 511, and the second annular protrusion 521. When it is necessary to maintain the linkage component 50 (such as cleaning tooth debris or replacing the rack), it is not necessary to disassemble the roller assembly inside the housing 10. Similarly, maintaining the internal roller does not affect the external linkage component 50, which greatly reduces the difficulty of maintenance.

[0056] Please refer to Figures 1 to 10 In one embodiment, the inner surface of the first annular protrusion 511 forms a first positioning groove 512, and the cleaning roller 20 is provided with a positioning fitting 21 on the side facing the first side plate 11. The positioning fitting 21 is disposed in the first positioning groove 512 and abuts against the groove wall of the first positioning groove 512.

[0057] The inner surface of the second annular protrusion 521 forms a second positioning groove 522. The auxiliary roller 40 is provided with a positioning protrusion 41 on the side facing the first side plate 11. The positioning protrusion 41 is located in the second positioning groove 522 and abuts against the groove wall of the second positioning groove 522.

[0058] The inner surface of the first annular protrusion 511 is not a smooth circle, but rather encloses and forms the first positioning groove 512. The irregular shape means that the cross-section of the groove is not circular (such as square, hexagonal, D-shaped or irregular shape with flat key), and the groove wall has a plane or a vertical surface at a specific angle.

[0059] Correspondingly, the cleaning roller 20 is provided with the positioning fitting 21 on the side facing the first side plate 11, and the shape of the positioning fitting 21 is completely matched with the first positioning groove 512. During assembly, the positioning fitting 21 is inserted into the first positioning groove 512, and its outer surface is completely in contact with the groove wall to form a rigid connection.

[0060] The irregular structure is rigidly connected to the plane or vertical surface. When it rotates, the positioning and mating parts 21 will directly push the side of the groove wall of the first positioning groove 512, forcing the two to rotate synchronously, so as to achieve lossless power transmission.

[0061] The inner surface of the second annular protrusion 521 forms a second positioning groove 522 (also with a non-circular cross-section), and the auxiliary roller 40 has a positioning protrusion 41 on the side facing the first side plate 11, the shape of which precisely matches the second positioning groove 522. During assembly, the positioning protrusion 41 is inserted into the second positioning groove 522, and its outer surface completely abuts against the groove wall to form a rigid fit.

[0062] The irregular structure is rigidly abutted by the plane or vertical surface. When rotating, the groove wall of the second positioning groove 522 will directly push the side of the positioning protrusion 41, forcing the two to rotate synchronously, so as to achieve lossless power transmission.

[0063] Please refer to Figures 1 to 10 In one embodiment, the cleaning device 100 further includes a first rotating support 61 and a second rotating support 62. The first rotating support 61 is sleeved on the outer surface of the first annular protrusion 511 and is respectively connected to the first annular protrusion 511 and the first side plate 11. The second rotating support 62 is sleeved on the outer surface of the second annular protrusion 521 and is respectively connected to the second annular protrusion 521 and the first side plate 11.

[0064] The first rotating support 61 is sleeved on the outer surface of the first annular protrusion 511, with the inner ring fitting against the outer surface of the first annular protrusion 511 and the outer ring fitting against the first side plate 11. This can prevent the first annular protrusion 511 from contacting and interfering with the first side plate 11 while rotating, thereby improving the smoothness of the linkage between the cleaning roller 20 and the auxiliary roller 40.

[0065] The structure of the second rotating support 62 is the same as that of the first rotating support 61. The second rotating support 62 is sleeved on the outer surface of the second annular protrusion 521. The inner ring is connected to the second annular protrusion 521, and the outer ring is connected to the wall of the second through hole on the first side plate 11. This can prevent the second annular protrusion 521 from contacting and interfering with the inner wall of the second through hole while rotating, thereby improving the smoothness of the linkage between the cleaning roller 20 and the auxiliary roller 40.

[0066] Please refer to Figures 1 to 10 In one embodiment, the housing 10 further includes a second side plate 12, which is disposed at a distance from the first side plate 11. The second side plate 12 is provided with a third annular protrusion 121 on the side facing the cleaning roller 20. The cleaning device 100 further includes a third rotating support member 63, which is sleeved on the outer periphery of the third annular protrusion 121. The cleaning roller 20 is sleeved on the outer periphery of the third rotating support member 63.

[0067] It should be noted that the cleaning roller 20 needs to rotate continuously (to contact the surface to be cleaned to achieve cleaning, and at the same time, to squeeze out wastewater in conjunction with the squeezing structure), and is an actively rotating component. The third rotating support 63 is sleeved on the outer periphery of the third annular protrusion 121, and the cleaning roller 20 is sleeved on the outer periphery of the third rotating support 63, forming a nested structure in which the third annular protrusion 121 is stationary, and the third rotating support 63 and the cleaning roller 20 rotate. The inner ring of the third support is fixed to the outer periphery of the third annular protrusion 121 (because the third annular protrusion 121 belongs to the fixed structure of the second side plate 12 and is stationary as a whole), and the outer ring of the third rotating support 63 is connected to the inner wall of the cleaning roller 20 (rotating synchronously with the cleaning roller 20). The inner and outer rings of the third rotating support 63 achieve relative rotation through rolling elements (balls or rollers), which can both support the rotation of the cleaning roller 20 and physically isolate the rotation of the cleaning roller 20 from the annular protrusion.

[0068] Optionally, the first rotating support 61 may include, but is not limited to, a bearing or a bushing, the second rotating support 62 may include, but is not limited to, a bearing or a bushing, and the third rotating support 63 may include, but is not limited to, a bearing or a bushing.

[0069] Please refer to Figures 1 to 10 In one embodiment, the cleaning roller 20 includes a fixing component 22 having a receiving hole 23, and the positioning fitting 21 passing through the receiving hole 23. The cleaning device 100 further includes a first elastic element 71 located within the receiving hole 23. One end of the first elastic element 71 is connected to the fixing component 22, and the other end is connected to the positioning fitting 21. The positioning fitting 21 slides relative to the fixing component 22 along a first direction to separate the positioning fitting 21 from the first positioning groove 512. The first elastic element 71 is in a compressed state. The first elastic element 71 in the compressed state enables the positioning fitting 21 to slide along a second direction opposite to the first direction to engage with the first positioning groove 512.

[0070] The cleaning roller 20 includes a fixing component 22 disposed on the side of the cleaning roller 20 near the first side plate 11. The fixing component 22 has a receiving hole 23, and the positioning fitting 21 passes through the receiving hole 23 and is slidable relative to the fixing component 22 along a first direction. Specifically, the first direction is the direction away from the first side plate 11 in the axial direction of the cleaning roller 20. Therefore, when the positioning fitting 21 slides along the first direction, the positioning fitting 21 can separate from the first side plate 11, thereby allowing the cleaning roller 20 to be detached from the first side plate 11 of the housing 10.

[0071] When the cleaning roller 20 needs to be inserted into the receiving space of the housing 10, the first elastic member 71, in a compressed state, allows the positioning fitting member 21 to slide along the second direction. Specifically, the second direction is the axial direction of the cleaning roller 20, closer to the first side plate 11. Therefore, when the positioning fitting member 21 slides along the second direction, it abuts against the first side plate 11, causing it to engage with the first side plate 11 of the housing 10, thereby fixing the cleaning roller 20 to the first side plate 11 of the housing 10.

[0072] It should be noted that, in this embodiment, when the positioning fitting 21 is engaged with the first side plate 11 of the housing 10, the first elastic member 71 is in a compressed state, and the first elastic member 71 continuously abuts against the positioning fitting 21 to support the positioning fitting 21 in continuously abutting against the first side plate 11 of the housing 10, thereby improving the engagement stability between the positioning fitting 21 and the first side plate 11, and thus improving the stability of the cleaning roller 20 fixed to the housing 10. In other embodiments, when the positioning fitting 21 is engaged with the first side plate 11 of the housing 10, the first elastic member 71 may also be in a balanced state, and this application does not limit this.

[0073] The first elastic member 71 connects the fixing component 22 and the positioning fitting member 21, and the positioning fitting member 21 can slide relative to the fixing component 22 to engage with the inner wall of the housing 10 or separate from the inner wall of the housing 10, so as to facilitate the assembly of the cleaning roller 20 with the housing 10 or the removal of the cleaning roller 20 from the housing 10.

[0074] Furthermore, in this embodiment, the first rotating member 51 is provided with a mounting through hole that communicates with the first positioning groove 512. The mounting through hole facilitates the user to press the positioning mating member 21, making it convenient for the user to remove the cleaning roller 20 from the first side plate 11.

[0075] Please refer to Figures 1 to 10 In one embodiment, the cleaning device 100 further includes a button assembly 80, which is disposed on the second side plate 12 and connected to one end of the auxiliary roller 40. The auxiliary roller 40 has a blind hole, and the button assembly 80 is at least partially disposed in the blind hole. The cleaning device 100 also includes a second elastic member 72, which is disposed in the blind hole, with one end of the second elastic member 72 connected to the button assembly 80 and the other end connected to the bottom wall of the blind hole.

[0076] The button assembly 80 slides relative to the second side plate 12 along the second direction to separate the button assembly 80 from the second side plate 12, and the second elastic member 72 is in a compressed state; the second elastic member 72 in the compressed state enables the button assembly 80 to slide along a first direction opposite to the second direction to engage the button assembly 80 within the second side plate 12.

[0077] The auxiliary roller 40 has the blind hole, and the button assembly 80 is at least partially disposed within the blind hole, and the button assembly 80 is slidable relative to the inner wall of the blind hole along the second direction. Specifically, the second direction is the direction away from the second side plate 12 in the axial direction of the cleaning roller 20. Therefore, when the button assembly 80 slides along the second direction, the button assembly 80 can be separated from the second side plate 12, thereby enabling the auxiliary roller 40 to be detached from the second side plate 12 of the housing 10.

[0078] When the auxiliary roller 40 needs to be inserted into the receiving space of the housing 10, the second elastic member 72, in a compressed state, allows the button assembly 80 to slide along the first direction. Specifically, the first direction is the axial direction of the cleaning roller 20, closer to the second side plate 12. Therefore, when the button assembly 80 slides along the first direction, the button assembly 80 can abut against the second side plate 12, causing the button assembly 80 to engage with the second side plate 12 of the housing 10, thereby fixing the auxiliary roller 40 to the second side plate 12 of the housing 10.

[0079] It should be noted that, in this embodiment, when the button assembly 80 is engaged with the second side plate 12 of the housing 10, the second elastic member 72 is in a compressed state, and the second elastic member 72 continuously abuts against the button assembly 80 to support the button assembly 80 in continuously abutting against the second side plate 12 of the housing 10, thereby improving the engagement stability between the button assembly 80 and the second side plate 12, and thus improving the stability of the auxiliary roller 40 fixed to the housing 10. In other embodiments, when the button assembly 80 is engaged with the second side plate 12 of the housing 10, the second elastic member 72 may also be in a balanced state, and this application does not limit this.

[0080] The auxiliary roller 40 and the button assembly 80 are connected by the second elastic member 72, and the button assembly 80 can slide relative to the auxiliary roller 40 to engage with or separate from the inner wall of the housing 10, so as to facilitate the assembly of the auxiliary roller 40 to the housing 10 or the removal of the auxiliary roller 40 from the housing 10.

[0081] Furthermore, in this embodiment, the second side plate 12 is provided with a mounting through hole for receiving the button assembly 80. The mounting through hole facilitates the user to press the button assembly 80 and makes it convenient for the user to remove the auxiliary roller 40 from the second side plate 12.

[0082] Please refer to Figures 1 to 10This application also provides a cleaning machine 1000, which includes a handle 200 and the cleaning device 100, wherein the handle 200 is connected to the end of the cleaning device 100 away from the cleaning roller 20.

[0083] It should be noted that in this embodiment, the cleaning machine 1000 is a manual cleaning machine. The user pushes the cleaning device 100 of the cleaning machine 1000 forward and cleans the surface to be cleaned. The cleaning roller 20 contacts the surface to be cleaned and rotates passively. While the cleaning roller 20 is rotating, it drives the auxiliary roller 40 to rotate, so as to sweep the garbage of the cleaning roller 20 into the garbage box assembly 30 for collection.

[0084] In the cleaning machine 1000 provided in this application, the housing 10 encloses and forms a receiving space. The cleaning roller 20 is disposed within the receiving space, rotatably connected to the housing 10, and can be used to clean surfaces to be cleaned. The two ends of the waste container assembly 30 are rotatably connected to the outer walls of the housing 10, and the waste container assembly 30 encloses and forms a receiving space, which communicates with the receiving space. The auxiliary roller 40 is disposed within the receiving space, rotatably connected to the housing 10, and when rotating, the auxiliary roller 40 abuts against the cleaning roller 20, brushing away debris adhering to the outer surface of the cleaning roller 20 into the receiving space of the waste container. The linkage assembly 50 is disposed on the side of the housing 10, and the linkage assembly 50 connects the cleaning roller 20 and the auxiliary roller 40 respectively, so that the rotation of the cleaning roller 20 simultaneously drives the rotation of the auxiliary roller 40. The linkage component 50 enables the cleaning roller 20 and the auxiliary roller 40 to form a linkage mechanism, so that the cleaning roller 20 and the auxiliary roller 40 always maintain a stable contact pressure and friction frequency, which can ensure the timeliness and effectiveness of the self-cleaning of the cleaning machine 1000. Furthermore, there is no need to design a separate power source for the auxiliary roller 40, which can simplify the internal structure of the cleaning machine 1000 and reduce the cost of the cleaning machine 1000.
