Description

Technical Field

[0001] This application belongs to the technical field of sweeping and mopping cleaning devices, specifically involving cleaning devices and sweeping and mopping integrated machines. Background Technology

[0002] In sweeping and mopping robots, the brush roller is typically used in conjunction with the flexible cleaning roller to sweep away debris and collect it into the dustbin. However, because the flexible cleaning roller usually absorbs a lot of water during operation, the brush roller can easily sweep away debris and water along with the flexible cleaning roller when it comes into contact with it. This results in greater resistance to the rotation of the brush roller and a heavier load on the drive motor. Utility Model Content

[0003] In view of this, the first aspect of this application provides a cleaning device, the cleaning device comprising:

[0004] A flexible cleaning roller is used to hold the surface to be cleaned. The flexible cleaning roller can absorb liquid and remove debris placed on the surface to be cleaned.

[0005] A brush roller is disposed on one side of the flexible cleaning roller, and the brush roller is farther away from the surface to be cleaned relative to the flexible cleaning roller. The brush roller is used to sweep away the debris placed on the flexible cleaning roller.

[0006] The brush roller includes a cylinder and a plurality of cleaning bristles disposed on the outer peripheral sidewall of the cylinder. The cleaning bristles have a preset tilt angle, which is the angle between the extension direction of the cleaning bristles and the tangential direction of the cylinder, and the preset tilt angle is an acute angle.

[0007] The plurality of cleaning bristles are spaced apart along the axial direction of the cylinder to form a cleaning brush group. The brush roller includes a plurality of cleaning brush groups, which are spaced apart along the circumferential direction of the cylinder on the outer peripheral sidewall of the cylinder.

[0008] In one of the cleaning brush groups, the multiple cleaning bristles are arranged in a V-shape, a straight line, or a spiral shape.

[0009] In one of the cleaning brush groups, the plurality of cleaning bristles include central bristles located in the middle of the cylinder and side bristles located on opposite sides of the central bristles, the central bristles and the side bristles being arranged in a V-shape.

[0010] The flexible cleaning roller has a contact surface for contacting the plurality of cleaning bristles. When the brush roller rotates and one of the cleaning bristle groups abuts the contact surface, the side bristles abut the contact surface before the center bristles.

[0011] In one of the cleaning brush groups, the preset tilt angle of the cleaning brush bristles gradually increases along the arrangement direction from the side bristles to the middle bristles.

[0012] Alternatively, within one of the cleaning brush groups, the preset tilt angle of the cleaning brush bristles gradually decreases along the arrangement direction from the side bristles to the center bristles.

[0013] The brush roller further includes a plurality of end bristles spaced apart on the outer peripheral sidewall of the cylinder along the circumferential direction of the cylinder body. The plurality of end bristles are located at the ends of the cylinder body, and the length of the plurality of end bristles is shorter than the length of the cleaning bristles, which are closer to the ends of the cylinder body than the cleaning bristles.

[0014] Wherein, the extension direction of the end bristles is perpendicular to the tangential direction of the cylinder; or, the angle between the extension direction of the end bristles and the tangential direction of the cylinder is an acute angle.

[0015] The inner circumferential sidewall of the cylinder has a hole, and the cleaning device also includes a drive motor connected to the brush roller. The drive motor is used to drive the brush roller to rotate. The drive motor is located in the hole, and the end bristles are located at the end of the cylinder corresponding to the drive motor.

[0016] The cleaning device further includes a cleaning shovel and a trash can. The cleaning shovel is disposed between the flexible cleaning roller and the trash can. The brush roller and the cleaning shovel are disposed on the same side of the flexible cleaning roller, and the cleaning shovel is closer to the surface to be cleaned than the brush roller.

[0017] When the flexible cleaning roller and the brush roller rotate, the flexible cleaning roller sweeps away the garbage placed on the surface to be cleaned, the cleaning shovel collects and guides the garbage to move, and the brush roller sweeps the garbage into the garbage box.

[0018] The second aspect of this application provides a sweeping and mopping machine, which includes a control component and a cleaning device as provided in the first aspect of this application. The control component is disposed on the cleaning device and is used to control the operation of the cleaning device.

[0019] The cleaning device and sweeping / mopping machine provided in this application reduce the likelihood of the brush roller sweeping away water from the flexible cleaning roller by tilting the cleaning bristles of the brush roller at an acute angle to the tangential direction between the extension direction of the cleaning bristles and the cylinder body. This reduces the resistance of the brush roller rotation and lowers the load on the drive motor. Furthermore, compared to the cleaning bristles that are vertically arranged on the cylinder body in related technologies, the brush roller provided in this embodiment can save 20%-30% of electricity, reducing energy consumption and saving energy.

[0020] Therefore, by tilting the cleaning bristles on the brush roller, this application reduces the likelihood of the brush roller sweeping away the water from the flexible cleaning roller, reduces the resistance to the rotation of the brush roller, lowers the load on the drive motor, reduces energy consumption, and saves energy.

Detailed Implementation

[0030] The following are preferred embodiments of this application. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of this application, and these improvements and modifications are also considered to be within the scope of protection of this application.

[0031] In view of this, in order to solve the above problems, please refer to the following: Figures 1-5 This embodiment provides a cleaning device 1, which includes a flexible cleaning roller 11 and a brush roller 12. The flexible cleaning roller 11 is used to hold the surface to be cleaned, and the flexible cleaning roller 11 can absorb liquid and sweep away debris placed on the surface to be cleaned; the brush roller 12 is disposed on one side of the flexible cleaning roller 11, and the brush roller 12 is farther away from the surface to be cleaned relative to the flexible cleaning roller 11, and the brush roller 12 is used to sweep away debris placed on the flexible cleaning roller 11.

[0032] The brush roller 12 includes a cylinder 121 and a plurality of cleaning bristles 122 disposed on the outer peripheral sidewall of the cylinder 121. The cleaning bristles 122 have a preset tilt angle, which is the angle between the extension direction of the cleaning bristles 122 and the tangential direction of the cylinder 121, and the preset tilt angle is an acute angle.

[0033] The cleaning device 1 provided in this embodiment mainly includes a flexible cleaning roller 11 and a brush roller 12. However, this does not mean that the cleaning device 1 can only include these two structures. The cleaning device 1 may include a housing 16, a bracket, a filter element, a cleaning shovel 14, a garbage box 15, a motor, a clean water tank, a wastewater tank, a water pump, an air pump, etc.

[0034] The brush roller 12, fixing assembly, flexible cleaning roller 11, support, filter, cleaning shovel 14, waste container 15, motor, clean water tank, wastewater tank, water pump, and air pump are all housed within the casing 16. The support and cleaning shovel 14 are located on opposite sides of the flexible cleaning roller 11. The cleaning shovel 14 and brush roller 12 are located on the side of the flexible cleaning roller 11 away from the support. The cleaning shovel 14 is located between the flexible cleaning roller 11 and the waste container 15. The brush roller 12 is further away from the surface to be cleaned than the cleaning shovel 14. The support surface facing the flexible cleaning roller 11 has extrusion protrusions, which are used to extrude wastewater from the flexible cleaning roller 11.

[0035] The flexible cleaning roller 11 is capable of absorbing liquid and is elastic. The flexible cleaning roller 11 is used to sweep away debris and remove dirt from the surface to be cleaned. A support bracket is used to cooperate with the flexible cleaning roller 11 to achieve a seal and to squeeze out wastewater from the roller. A filter element is used to filter impurities from the wastewater.

[0036] The outer periphery of the brush roller 12 is provided with cleaning bristles 122, and the brush roller 12 is used to sweep away the debris from the self-cleaning roller 11. The cleaning shovel 14 is used to collect and guide the movement of debris, and the debris box 15 is used to store debris. The debris removed by the self-cleaning shovel 14 can be stored in the debris box 15. The motor is used to drive the rotation of the self-cleaning roller 11 and also to drive the rotation of the brush roller 12.

[0037] The clean water tank stores clean water, and the wastewater tank stores wastewater. A water pump draws clean water from the clean water tank and outputs it to the flexible cleaning roller 11. An air pump evacuates the wastewater tank, creating a negative pressure environment that draws wastewater into it.

[0038] The support frame has a water flow channel for storing and guiding wastewater from the flexible cleaning roller 11. The housing 16 has a clean water pipe and a wastewater pipe. The clean water pipe connects the clean water tank to one end of the water flow channel, and the wastewater pipe connects the wastewater tank to the other end of the water flow channel. The clean water pipe is used to input clean water, and the wastewater pipe is used to discharge wastewater. When the flexible cleaning roller 11 rotates, the clean water in the clean water tank flows to the flexible cleaning roller 11 through the clean water pipe and the water flow channel. Meanwhile, the wastewater in the flexible cleaning roller 11 is squeezed out by the extrusion protrusions on the support frame, and the wastewater flows to the wastewater tank through the water flow channel and the wastewater pipe, thereby cleaning the flexible cleaning roller 11.

[0039] Optionally, the cleaning device 1 further includes two seals respectively disposed at opposite ends of the bracket, the two seals being used to seal the water flow channel. A clean water pipe passes through one seal and connects to the water flow channel, while a wastewater pipe passes through the other seal and connects to the water flow channel.

[0040] This application also provides a sweeping and mopping robot 2, which includes a control component and a cleaning device 1. The control component is disposed on the cleaning device 1. The control component includes a controller and a sensor electrically connected to each other. The sensor is used to acquire sensing information and send the sensing information to the controller. The controller is used to receive the sensing information and control the cleaning device 1 to operate according to the sensing information.

[0041] The sweeper-mop combo 2 also includes a moving component, which is located on the cleaning device 1 and is used to move the cleaning device 1 and the control component. Optionally, the moving component includes multiple wheels that can rotate relative to the surface to be cleaned, thereby moving the sweeper-mop combo 2 and the control component.

[0042] When the sweeper and mop 2 is sweeping, the motor drives the flexible cleaning roller 11 to rotate in the first cleaning direction, and also drives the brush roller 12 to rotate in the first cleaning direction. The rotation direction of the moving components is the same as the first cleaning direction. As the flexible cleaning roller 11 sweeps away the garbage placed on the surface to be cleaned, the cleaning blades 14 collect and guide the garbage to move, and the brush roller 12 sweeps the garbage on the flexible cleaning roller 11 into the garbage box 15. Here, garbage refers to unwanted or useless solid or liquid substances, which are waste generated by users in production, consumption, daily life, and other activities. Examples include used toilet paper, scattered vegetable roots, and fruit peels. The first cleaning direction is as follows: Figure 2 The direction is shown in D1.

[0043] When the sweeper and mop combo 2 is mopping, the motor drives the flexible cleaning roller 11 to rotate in a second cleaning direction. The rotation direction of the moving component is opposite to the second cleaning direction to remove dirt from the surface to be cleaned. The second cleaning direction is opposite to the first cleaning direction. Dirt refers to mud, oil stains, or other impurities that have soiled the surface to be cleaned; dirt can adhere to the surface of an object. For example, dust, oil stains, etc. The second cleaning direction is as follows: Figure 2 The direction is shown in D2.

[0044] It should be noted that the working order of the various structural components of the sweeping and mopping machine 2 mentioned above is not important and should not be construed as a limitation of this application.

[0045] The inner wall of the housing 16 provided in this embodiment forms a receiving space. The brush roller 12, at least a portion of the flexible cleaning roller 11, at least a portion of the cleaning shovel 14, and the trash can 15 are disposed within the receiving space.

[0046] The flexible cleaning roller 11 provided in this embodiment is used to sweep away debris placed on the surface to be cleaned, and also to remove dirt placed on the surface to be cleaned. The flexible cleaning roller 11 can rotate along its own axis, and the outer periphery of the flexible cleaning roller 11 is made of flexible material, which can adsorb tiny dust particles, impurities, and other substances. The flexible cleaning roller 11 rubs against the surface to be cleaned to adsorb dirt, debris, and other substances on the surface to be cleaned onto the flexible cleaning roller 11, thereby achieving cleaning of the surface to be cleaned.

[0047] The brush roller 12 provided in this embodiment includes a cylinder 121 and a plurality of cleaning bristles 122. The plurality of cleaning bristles 122 are disposed on the outer peripheral sidewall of the cylinder 121, and the inner peripheral sidewall of the cylinder 121 forms a hole 1211. The plurality of cleaning bristles 122 are used to sweep the debris on the flexible cleaning roller 11 into the debris box 15. Optionally, a drive motor 13 is disposed in the hole 1211, and the drive motor 13 is used to drive the brush roller 12 to rotate. Optionally, a fixing component is disposed in the hole 1211, and the fixing component can be snapped onto the inner sidewall of the housing 16. The fixing component is used to connect the brush roller 12 and the housing 16, thereby fixing the brush roller 12 inside the housing 16. Alternatively, the drive motor 13 and the fixing component are located at opposite ends of the cylinder 121. For example, when the hole 1211 penetrates the cylinder 121 along the axial direction of the cylinder 121, the drive motor 13 is located on one side of the hole 1211 and the fixing component is located on the other side of the hole 1211. Or, for example, two holes 1211 are provided at opposite ends of the cylinder 121, the drive motor 13 is located in one hole 1211 and the fixing component is located in the other hole 1211.

[0048] The cleaning bristles 122 have a preset tilt angle, which can also be understood as the cleaning bristles 122 being inclinedly disposed on the outer peripheral sidewall of the cylinder 121. The cleaning bristles 122 have a preset tilt angle α, and the preset tilt angle α is an acute angle. The preset tilt angle α satisfies: 0° < α < 90°. Specific examples of the preset tilt angle α are 5°, 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, or 85°, etc. Preferably, the preset tilt angle α satisfies: 20° ≤ α ≤ 70°; more preferably, the preset tilt angle α satisfies: 30° ≤ α ≤ 60°; even more preferably, the preset tilt angle α satisfies: 40° ≤ α ≤ 50°.

[0049] The cleaning device 1 provided in this embodiment reduces the likelihood of the brush roller 12 sweeping away water from the flexible cleaning roller 11 by tilting the cleaning bristles 122 of the brush roller 12 so that the extension direction of the cleaning bristles 122 is at an acute angle to the tangential direction between the brush roller 122 and the cylinder 121, thereby reducing the resistance to the rotation of the brush roller 12 and reducing the load on the drive motor 13. Furthermore, compared with the cleaning bristles 122 that are vertically arranged on the cylinder 121 in the related art, the brush roller 12 provided in this embodiment can save 20%-30% of electricity, reduce energy consumption, and save energy.

[0050] Therefore, by tilting the cleaning bristles 122 on the brush roller 12, this embodiment reduces the probability of the brush roller 12 sweeping away the water from the flexible cleaning roller 11, reduces the resistance to the rotation of the brush roller 12, reduces the load on the drive motor 13, reduces energy consumption, and saves energy.

[0051] Please refer to this as well. Figures 1-5 In one embodiment, the plurality of cleaning bristles 122 are spaced apart along the axial direction of the cylinder 121 to form a cleaning brush group, and the brush roller 12 includes a plurality of cleaning brush groups, which are spaced apart along the circumferential direction of the cylinder 121 on the outer peripheral sidewall of the cylinder 121.

[0052] Within a cleaning brush assembly, multiple cleaning bristles 122 are spaced apart along the axial direction of the cylinder 121. Specifically, within the cleaning brush assembly, the multiple cleaning bristles 122 are arranged in a V-shape, a straight line, or a spiral. Optionally, within a cleaning brush assembly, the spacing between two adjacent cleaning bristles 122 is equal; or, at least some of the cleaning bristles 122 have unequal spacing. Optionally, within a cleaning brush assembly, the preset cleaning angles of the cleaning bristles 122 are all the same; or, at least some of the cleaning bristles 122 have the same preset cleaning angle; or, the preset cleaning angles of the cleaning bristles 122 are all different. Optionally, along the axial direction of the cylinder 121, within a cleaning brush assembly, the preset cleaning angle of the cleaning bristles 122 gradually increases or gradually decreases. Optionally, along the axial direction of the cylinder 121, within a cleaning brush assembly, the preset cleaning angle of the cleaning bristles 122 exhibits a non-linear variation.

[0053] The outer peripheral sidewall of the cylinder 121 is provided with multiple cleaning brush groups. Optionally, the number of cleaning brush groups is 4 to 8, and the specific number of cleaning brush groups can be 4, 5, 6, 7, or 8, etc. Optionally, the spacing between two adjacent cleaning brush groups is equal; or, at least some of the cleaning brush groups are not equidistant.

[0054] In summary, by providing a cleaning brush assembly consisting of multiple cleaning bristles 122 on the cylinder 121, this embodiment can reduce the probability of the brush roller 12 sweeping away the water from the flexible cleaning roller 11, reduce the resistance of the brush roller 12 rotation, and improve the cleaning effect of the brush roller 12 in removing debris, thereby improving the cleaning effect of the cleaning device 1.

[0055] Furthermore, the cleaning bristles 122 of this embodiment can be arranged in a V-shape, a straight line, or a spiral shape according to product requirements, adapting to various usage scenarios, thereby further improving the cleaning effect of the brush roller 12 in sweeping away garbage, and further improving the cleaning effect of the cleaning device 1.

[0056] Please refer to this as well. Figures 1-5 In one embodiment, within one of the cleaning brush assemblies, the plurality of cleaning bristles 122 include a central bristle 122a disposed in the middle of the cylinder 121 and side bristles 122b disposed on opposite sides of the central bristle 122a, the central bristle 122a and the side bristles 122b being arranged in a V-shape.

[0057] The flexible cleaning roller 11 has a contact surface for contacting the plurality of cleaning bristles 122. When the brush roller 12 rotates and one of the cleaning bristle groups abuts the contact surface, the side bristles 122b abut the contact surface first than the middle bristles 122a.

[0058] Along the axial direction of the cylinder 121, side brush bristles 122b, central brush bristles 122a, and side brush bristles 122b are arranged sequentially and form a V-shape. Alternatively, the central brush bristles 122a can be understood as being positioned further forward on the cylinder 121 than the side brush bristles 122b. The central brush bristles 122a are located in the middle portion of the outer peripheral sidewall of the cylinder 121, while the side brush bristles 122b are located on the side portions of the outer peripheral sidewall of the cylinder 121, with the side portions situated on equal sides of the middle portion.

[0059] Specifically, when the flexible cleaning roller 11 rotates along the first cleaning direction, the brush roller 12 also rotates along the first cleaning direction. The cleaning bristles 122 abut against the surface to be cleaned on the flexible cleaning roller 11 to sweep the debris from the flexible cleaning roller 11 into the debris box 15. As the brush roller 12 rotates, the side bristles 122b and the middle bristles 122a abut against the contact surface in sequence. The side bristles 122b and the middle bristles 122a make more full contact with the debris on the flexible cleaning roller 11, making it easier to sweep the debris off the flexible cleaning roller 11 and improving the cleaning effect of the brush roller 12 in removing debris.

[0060] In summary, this embodiment limits the arrangement of the central bristles 122a and the side bristles 122b of a cleaning brush group to form a V-shape, and limits the contact sequence of the central bristles 122a and the side bristles 122b, making it easier for the brush roller 12 to sweep away the debris on the flexible cleaning roller 11, thereby further improving the cleaning effect of the brush roller 12 in removing debris and further improving the cleaning effect of the cleaning device 1.

[0061] In one embodiment, within one of the cleaning brush groups, the preset tilt angle of the cleaning brush bristles 122 gradually increases along the arrangement direction from the side bristles 122b to the center bristles 122a.

[0062] Alternatively, within one of the cleaning brush groups, the preset tilt angle of the cleaning brush bristles 122 gradually decreases along the arrangement direction from the side bristles 122b to the center bristles 122a.

[0063] Optionally, the preset tilt angles of the side brushes 122b on both sides of the central brush 122a are symmetrically arranged along the centerline of the cylinder 121.

[0064] Therefore, by further defining the preset tilt angle relationship between the central bristles 122a and the side bristles 122b, this embodiment makes it easier for the brush roller 12 to sweep away the garbage on the flexible cleaning roller 11, thereby further improving the cleaning effect of the brush roller 12 in removing garbage and further improving the cleaning effect of the cleaning device 1.

[0065] Please refer to this as well. Figures 1-5 In one embodiment, the brush roller 12 further includes a plurality of end bristles 123 spaced apart on the outer peripheral sidewall of the cylinder 121 along the circumferential direction of the cylinder 121. The plurality of end bristles 123 are located at the ends of the cylinder 121, and the plurality of end bristles 123 are closer to the ends of the cylinder 121 than the cleaning bristles 122. The length of the end bristles 123 is less than the length of the cleaning bristles 122.

[0066] Multiple end bristles 123 are used to wrap around hair, preventing hair from accumulating in the gap between the housing 16 and the brush roller 12, which could cause the brush roller 12 to malfunction. Optionally, multiple cleaning bristles 122 are spaced apart along the circumferential direction of the cylinder 121 to form an end brush group, and the brush roller 12 includes at least one end brush group. Optionally, the multiple end bristles 123 are located at the end of the cylinder 121 away from the fixing component, and the multiple end bristles 123 are farther away from the fixing component than the multiple cleaning bristles 122.

[0067] Therefore, by providing end bristles 123 at the end of the cylinder 121, this embodiment enables the end bristles 123 to wrap around hair, which not only makes it easier for users to clean and reduces the difficulty of cleaning, but also prevents hair from accumulating in the gap between the housing 16 and the brush roller 12, which would cause the brush roller 12 to malfunction and improve the working reliability of the brush roller 12.

[0068] In one embodiment, the extension direction of the end bristles 123 is perpendicular to the tangential direction of the cylinder 121; or, the angle between the extension direction of the end bristles 123 and the tangential direction of the cylinder 121 is an acute angle.

[0069] For example, the angle between the extending direction of the end bristles 123 and the tangential direction of the cylinder 121 is 90°. Alternatively, the angle between the extending direction of the end bristles 123 and the tangential direction of the cylinder 121 may be an acute angle, specifically 5°, 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, or 85°, etc. Preferably, the angle between the extending direction of the end bristles 123 and the tangential direction of the cylinder 121 is 20°-70°; more preferably, the angle between the extending direction of the end bristles 123 and the tangential direction of the cylinder 121 is 30°-60°; even more preferably, the angle between the extending direction of the end bristles 123 and the tangential direction of the cylinder 121 is 40°-50°.

[0070] Therefore, this embodiment further improves the effect of the end brush bristles 123 wrapping around hair by setting the end brush bristles 123 perpendicularly or obliquely to the cylinder 121, making it easier for users to clean, further reducing the difficulty of cleaning for users, further preventing hair from accumulating in the gap between the housing 16 and the brush roller 12, which would cause the brush roller 12 to malfunction, and further improving the working reliability of the brush roller 12.

[0071] Please refer to this as well. Figures 1-7 In one embodiment, the inner peripheral sidewall of the cylinder 121 forms a hole 1211. The cleaning device 1 also includes a drive motor 13 connected to the brush roller 12. The drive motor 13 is used to drive the brush roller 12 to rotate. The drive motor 13 is disposed in the hole 1211. The end bristles 123 are disposed at the ends of the cylinder 121 corresponding to the drive motor 13.

[0072] A drive motor 13 is connected to the cylinder 121, and the drive motor 13 can drive the cylinder 121 to rotate. At least a portion of the drive motor 13 is disposed within the hole 1211. Optionally, the cleaning device 1 further includes a housing 16 having a side plate 161, the brush roller 12 being disposed within the housing 16, the drive motor 13 being disposed on the side plate 161, and the end bristles 123 abutting against the inner surface of the side plate 161. Further optionally, the inner surface of the side plate 161 is provided with an annular groove 1611, the drive motor 13 being disposed within the annular groove 1611, and the end bristles 123 abutting against the groove wall of the annular groove 1611.

[0073] Optionally, the drive motor 13 is rotatably connected to the side plate 161 of the housing 16, and the drive motor 13 can swing relative to the side plate 161. When it is necessary to install the brush roller 12 onto the housing 16, the drive motor 13 is first tilted relative to the side plate 161, then the brush roller 12 is fitted onto the drive motor 13, and then the drive motor 13 is returned to its original position, swinging the drive motor 13 to be perpendicular to the side plate 161. The brush roller 12 is then fixed inside the housing 16 using the fixing components provided on the brush roller 12.

[0074] Therefore, this embodiment improves the working reliability of the brush roller 12 by placing the end bristles 123 at the end of the corresponding drive motor 13 to avoid hair from accumulating on the motor and causing the brush roller 12 to malfunction.

[0075] Please refer to this as well. Figures 1-7 In one embodiment, the cleaning device 1 further includes a cleaning shovel 14 and a trash can 15. The cleaning shovel 14 is disposed between the flexible cleaning roller 11 and the trash can 15. The brush roller 12 and the cleaning shovel 14 are disposed on the same side of the flexible cleaning roller 11, and the cleaning shovel 14 is closer to the surface to be cleaned than the brush roller 12.

[0076] When the flexible cleaning roller 11 and the brush roller 12 rotate, the flexible cleaning roller 11 sweeps away the garbage placed on the surface to be cleaned, the cleaning shovel 14 collects and guides the garbage to move, and the brush roller 12 sweeps the garbage into the garbage box 15.

[0077] Specifically, when the cleaning device 1 performs sweeping work, the flexible cleaning roller 11 rotates along the first cleaning direction, the brush roller 12 rotates along the first cleaning direction, and the rotation direction of the moving component in the sweeping and mopping machine 2 is the same as the first cleaning direction. As the flexible cleaning roller 11 sweeps away the garbage placed on the surface to be cleaned, the cleaning shovel 14 collects and guides the garbage to move, and the brush roller 12 sweeps the garbage on the flexible cleaning roller 11 into the garbage box 15.

[0078] Furthermore, when the cleaning device 1 performs mopping operations, the flexible cleaning roller 11 rotates along the second cleaning direction, and the rotation direction of the moving component in the sweeping and mopping machine 2 is opposite to the second cleaning direction, so as to remove dirt placed on the surface to be cleaned. The second cleaning direction is opposite to the first cleaning direction.

[0079] Therefore, this embodiment achieves sweeping work by setting up a cleaning shovel 14, a dustbin 15, a brush roller 12, and a flexible cleaning roller 11. Furthermore, the cleaning bristles 122 on the brush roller 12 are set at an angle to reduce the probability of the brush roller 12 sweeping water off the flexible cleaning roller 11, reduce the resistance of the brush roller 12 rotation, reduce the load on the drive motor 13, reduce energy consumption, and save energy.

[0080] Please refer to this as well. Figures 1-7 This application also provides a sweeping and mopping machine 2, which includes a control component and a cleaning device 1 as described above. The control component is disposed on the cleaning device 1 and is used to control the operation of the cleaning device 1.

[0081] The sweeper and mop combo 2 provided in this application adopts the cleaning device 1 provided in this application above, in which the cleaning bristles 122 of the brush roller 12 in the cleaning device 1 are inclined and the extension direction of the cleaning bristles 122 is set at an acute angle with the tangential direction between the brush roller 122 and the cylinder 121. This reduces the probability of the brush roller 12 sweeping away the water of the flexible cleaning roller 11, reduces the resistance of the brush roller 12 rotation, and reduces the load on the drive motor 13. Furthermore, compared with the cleaning bristles 122 that are vertically arranged in the cylinder 121 in the related art, the brush roller 12 provided in this embodiment can save 20%-30% of electricity, reduce energy consumption, and save energy.

[0082] Therefore, by tilting the cleaning bristles 122 on the brush roller 12, this application reduces the probability of the brush roller 12 sweeping away the water from the flexible cleaning roller 11, reduces the resistance to the rotation of the brush roller 12, reduces the load on the drive motor 13, reduces energy consumption, and saves energy.
