Cleaning device and cleaning robot

Abstract

The application relates to a cleaning device and a cleaning robot. The cleaning device comprises a frame and a cleaning support which is movably connected to the frame. The cleaning support can abut a working surface in the circumferential direction and is used to roll up and wind a mop in the circumferential direction and drive the mop to clean the working surface. Since the cleaning support can roll up and wind the mop in the circumferential direction, the mop with high dirtiness can be automatically wound on the cleaning support, so that the clean mop can be released to clean the working surface. Thus, the mop with high dirtiness can be prevented from being repeatedly used, the cleanliness of the mop is improved, and the cleaning effect of the cleaning device is improved.

Description

Technical Field

[0001] This application relates to the field of cleaning technology, and in particular to a cleaning device and a cleaning robot. Background Technology

[0002] Cleaning robots are robotic systems capable of autonomously or semi-autonomously performing environmental cleaning tasks. With the rapid development of sensor technology, artificial intelligence, computing power, and mechatronics, cleaning robots have evolved from simple automated equipment into intelligent agents with certain environmental perception, decision-making, planning, and task execution capabilities. Their application scenarios have also expanded from the initial household sweeping robots to commercial (such as shopping malls and office buildings), industrial (such as factory workshops and cleanrooms), and other specialized fields.

[0003] There is a type of cleaning robot whose flat mop is attached to the work surface with Velcro. However, this cleaning robot requires manual replacement of the mop, which is not convenient. In addition, the repeated use of the mop over a long period of time will affect the cleanliness of the mop, thereby affecting the cleaning effect of the cleaning robot. Utility Model Content

[0004] One of the technical problems addressed by this application is how to improve the cleaning effect of cleaning devices.

[0005] A cleaning device, comprising:

[0006] rack; and

[0007] A cleaning bracket is movably connected to the frame. The cleaning bracket can abut against the working surface in its circumferential direction. The cleaning bracket is used to roll up and wrap the mop in its circumferential direction, and to drive the mop to clean the working surface.

[0008] In one embodiment, the cleaning bracket includes a support member fixedly connected to the frame; and

[0009] The support includes a first bracket and a second bracket. The first bracket and the second bracket have parallel rollers on opposite sides. The two parallel rollers are used to drive the mop to rotate on the support.

[0010] Alternatively, the support may include two or more brackets, each bracket having parallel rollers on a side away from each other, the rollers being used to rotate the mop on the support.

[0011] In one embodiment, the cleaning bracket further includes an annular liner fitted onto the support member. As the parallel roller rotates along its axis, the liner rotates around the support member and causes the mop covering the liner to roll up to the support member.

[0012] In one embodiment, the cleaning support includes a roller rotatably connected to the frame.

[0013] In one embodiment, the frame is provided with a slot, and the roller can slide relative to the slot. When the number of layers of mop wrapped around the roller increases, the roller overcomes gravity and slides in the slot in a direction away from the working surface.

[0014] In one embodiment, the cross-section of the roller is circular or polygonal.

[0015] In one embodiment, the cleaning device further includes:

[0016] The discharging mechanism is used to collect the mop.

[0017] An output mechanism, comprising an output shaft, which is rotatably connected to the frame and disposed near the discharge mechanism, the output shaft being used to release or fix the mop from the discharge mechanism.

[0018] In one embodiment, the output shaft includes an output body and a guide that protrudes radially from the output body onto the output body, the guide being used to release or secure the mop.

[0019] In one embodiment, the output mechanism includes two output shafts, the guide is a toothed structure, the toothed structures on the two output shafts mesh with each other, and the two toothed structures are used to release or fix the mop.

[0020] In one embodiment, the guide on the output shaft further includes at least one of the following:

[0021] The guide includes hook and loop fasteners or adhesive, which can generate an adhesive force with the mop to release or secure the mop.

[0022] The guide includes an output protrusion, and the mop is provided with a positioning hole corresponding to the output protrusion. The output body can abut against the mop, and the output protrusion can extend into or out of the positioning hole to release or fix the mop.

[0023] The guide includes an output puncture, the output body being able to abut against the mop, and the output puncture being able to pierce or disengage from the mop to release or secure the mop.

[0024] In one embodiment, the output mechanism further includes an output baffle connected to the frame, the output baffle being further away from the discharge device relative to the output shaft along the output direction of the mop, and the output shaft and the output baffle abutting against the same side of the mop.

[0025] In one embodiment, the cleaning device further includes a discharge mechanism disposed on the frame, the discharge mechanism comprising:

[0026] The discharge roller includes a receiving cavity and through holes at both ends communicating with the receiving cavity. The discharge roller is used to store and wrap mop cloth.

[0027] An inner shaft passes through the receiving cavity, with both ends of the inner shaft extending out of the through hole and being mounted on the frame.

[0028] In one embodiment, the discharge mechanism further includes:

[0029] The pre-tightening structure has an inner ring fitted onto the inner shaft and an outer ring fixed to the cavity wall of the receiving cavity. The pre-tightening structure is used to create differential rotation between the discharge roller and the inner shaft.

[0030] In one embodiment, the pre-tightening structure includes a protrusion and an elastic component. The protrusion is located within the receiving cavity and protrudes from the outer peripheral surface of the inner shaft. The elastic component is connected to the cavity wall of the receiving cavity and elastically abuts against the protrusion.

[0031] A cleaning robot further includes a main unit and a cleaning device as described in any one of the above-mentioned methods, wherein the cleaning device is detachably connected to the main unit.

[0032] In one embodiment, the main unit is provided with a water outlet for spraying water onto a mop or work surface wrapped around the cleaning bracket.

[0033] One technical effect of one embodiment of this application is that, since the cleaning bracket can roll up and wrap the mop along its circumference, the mop with a high degree of dirtiness can be automatically wrapped around the cleaning bracket, thereby allowing the clean mop to be released to clean the work surface. This avoids the dirty mop being reused multiple times, thereby improving the cleanliness of the mop and ultimately improving the cleaning effect of the cleaning device. Attached Figure Description

Detailed Implementation

[0045] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0046] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0047] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0048] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0049] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0050] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0051] See Figure 1 and Figure 2 One embodiment of this application provides a cleaning robot 10, which includes a main unit and a cleaning device 11. The cleaning device 11 is mounted on the main unit, and for example, the cleaning device 11 can be detachably connected to the main unit, thus facilitating the maintenance of the cleaning robot 10. The cleaning device 11 includes a frame 100 and a cleaning support 200. The cleaning support 200 is movably connected to the frame 100. The circumferential direction of the cleaning support 200 can abut against the working surface. The cleaning support 200 is used to roll up and wrap the mop 12 along its circumference, and the cleaning support 200 can drive the mop 12 to clean the working surface, which can be a floor, tabletop, glass surface, etc. In this utility model, the mop refers to a cleaning material that can be used for mopping, sweeping, and washing, including dry cleaning materials for mopping and sweeping the working surface and wet cleaning materials for washing the working surface. The cleaning material here can be cotton, polyester fiber, or non-woven fabric, etc., and is not limited here. Furthermore, in this utility model, the working surface can be the ground, a tabletop, or a glass surface; that is, the cleaning robot provided by this utility model can be a sweeping robot, a tabletop cleaning robot, or a window cleaning robot.

[0052] Since the cleaning bracket 200 can retract and wrap the mop 12 circumferentially, the heavily soiled mop 12 can be automatically wrapped around the cleaning bracket 200, allowing the clean mop 12 to be released for cleaning the work surface. This avoids the dirty mop 12 being reused multiple times, thereby improving the cleanliness of the mop 12 and ultimately enhancing the cleaning effect of the cleaning device 11 and the entire cleaning robot 10. It is understood that the retraction of the mop 12 and the cleaning of the work surface by the mop 12 can be performed simultaneously or asynchronously.

[0053] See Figure 1 and Figure 2 In some embodiments, the cleaning support 200 can be a tracked structure. For example, the cleaning support 200 includes a support member 210, which can be generally flat. The support member 210 is fixedly connected to the frame 100. The support member 210 includes a first support 211 and a second support 212. The sides of the first support 211 and the second support 212 that are far apart from each other include parallel rollers 213. When the two parallel rollers 213 rotate, they can drive the mop 12 to rotate on the support member 210, thereby causing the mop 12 to be wrapped around the cleaning support 200. Alternatively, the support member 210 can be generally prismatic. The support member 210 includes two or more supports, and the sides of each support that are far apart from each other include parallel rollers 213. When multiple rollers 213 rotate, they drive the mop 12 to wrap around the cleaning support 200. It can be understood that when the number of supports is three, the support member 210 can be generally a triangular prism structure.

[0054] See Figure 1 and Figure 2 In some embodiments, when the cleaning bracket 200 has a tracked structure, it may further include an inner liner 220. The structure of the inner liner 220 matches the structure of the support member 210, allowing the inner liner 220 to be fitted onto the support member 210. When the rollers 213 rotate, the inner liner 220 will move circumferentially around the support member 210, i.e., the inner liner 220 will perform a tracked movement relative to the support member 210. One end of the mop 12 is fixedly connected to the inner liner 220. During the movement of the inner liner 220 relative to the support member 210, the mop 12 will wrap around the inner liner 220, thus achieving the winding and wrapping of the mop 12 by the entire cleaning bracket 200.

[0055] See Figure 3 and Figure 4In some embodiments, the cleaning support 200 can be a roller-type structure. In this case, the cleaning support 200 includes a roller 230, which is rotatably connected to the frame 100. One end of the mop 12 can be fixed to the roller 230. When the roller 230 rotates relative to the frame 100, the mop 12 can gradually wrap around the roller 230. The frame 100 can be provided with a slot 110, and the roller 230 can slide relative to the slot 110. As the number of layers of mop 12 wrapped around the roller 230 increases, the roller 230 overcomes gravity and slides away from the working surface within the slot 110. For example, when the work surface is the ground, as the number of layers of mop cloth 12 wound around the roller 230 gradually increases, the outer diameter of the rotating body formed by the roller 230 and the mop cloth 12 increases. Since the outermost layer of mop cloth 12 on the roller 230 will always remain in contact with the ground, the roller 230 gradually moves upward under the pushing force of the ground, thus gradually increasing the distance between the central axis of the roller 230 and the ground. This avoids interference between the ground and the roller 230, ensuring that the roller 230 can rotate smoothly relative to the frame 100, thereby achieving the winding and wrapping of the mop cloth 12. This ensures that the heavily soiled mop cloth 12 is gradually wrapped around the roller 230, allowing the clean mop cloth 12 to be released for cleaning the work surface. This avoids the dirty mop cloth 12 being reused multiple times, thereby improving the cleanliness of the mop cloth 12 and ultimately improving the cleaning effect of the cleaning robot 10.

[0056] In some embodiments, the cross-section of the roller 230 is circular, in which case the roller 230 can be understood as cylindrical; in some embodiments, the cross-section of the roller 230 can be polygonal, in which case the roller 230 can be understood as prismatic. It can be understood that when the roller 230 is prismatic, the mop 12 wound around the roller 230 has a surface-to-surface contact relationship with the working surface, which can reasonably increase the contact area between the mop 12 and the working surface, thereby reasonably improving the working efficiency and cleaning effect of the mop 12.

[0057] See Figure 5 In some embodiments, the cleaning device 11 further includes a dispensing mechanism 300 and an output mechanism 400. The dispensing mechanism 300 is used to receive clean mop cloths 12. The output mechanism 400 includes an output shaft 410, which is rotatably connected to the frame 100 and positioned close to the dispensing mechanism 300. The output shaft 410 is used to release or fix the mop cloth 12 from the dispensing mechanism 300. For example, the dispensing mechanism 300 may include a dispensing roller 310, which is rotatably connected to the frame 100. One end of the mop cloth 12 is fixedly connected to the dispensing roller 310. The clean mop cloth 12 can be wound around the dispensing roller 310, and when the dispensing roller 310 rotates, the clean mop cloth 12 will be gradually released from the dispensing roller 310. See also Figure 6For example, the discharging mechanism 300 includes a discharging box 330, which has a discharging chamber 331 and a discharging port 332. The discharging port 332 is connected to the discharging chamber 331. The discharging chamber 331 is used to hold the mop 12. The mop 12 passes through the discharging port 332 and extends out of the discharging chamber 331, so that the discharging port 332 is used to release the mop 12. It can be understood that when the mop 12 is housed in the discharging chamber 331, the mop 12 can be housed in the discharging chamber 331 in a stacked manner.

[0058] See Figure 5 In some embodiments, the output shaft 410 includes an output body 411 and a guide member 412, the guide member 412 being radially protruding from the output body 411. The guide member 412 is used to release or fix the mop 12. Therefore, by providing the output shaft 410, on the one hand, the mop 12 can be released from the discharge mechanism 300, thereby achieving the gradual release of the clean mop 12. On the other hand, it can provide a certain pre-tensioning or tensioning effect on the mop 12, so that the mop 12 located between the discharge mechanism 300 and the cleaning bracket 200 is in a flat state, avoiding wrinkles in the mop 12, thereby improving the cleaning effect of the mop 12 on the working surface.

[0059] See Figure 5 For example, the output mechanism 400 includes two output shafts 410, and the guide member 412 is a gear structure 4121. The gear structures 4121 on the two output shafts 410 mesh with each other. The two gear structures 4121 are used to release or fix the mop 12. In this case, the guide member 412 can be understood as a gear structure. The mop 12 is sandwiched between the guide members 412 of the two output shafts 410. When the two output shafts 410 rotate simultaneously, they can exert a pulling force on the mop 12, thereby causing the mop 12 to be gradually released from the discharge mechanism 300.

[0060] See Figure 6 For example, the guide 412 includes hook and loop fasteners 4122 or adhesive, which can generate an adhesive force with the mop 12. When the output shaft 410 rotates, the hook and loop fasteners 4122 or adhesive can release or fix the mop 12. The hook and loop fasteners 4122 or adhesive can cover part of the output body 411 or cover the entire output body 411.

[0061] See Figure 7For example, the guide member 412 includes an output protrusion 4123, and the mop 12 is provided with a positioning hole 12a corresponding to the output protrusion 4123. The output body 411 can abut against the mop 12, and the output protrusion 4123 can extend into or disengage from the positioning hole 12a to release or fix the mop 12. The output protrusions 4123 are arranged in one or more rows along the axial direction of the output body 411, and multiple output protrusions 4123 in the same row are spaced apart along the circumference of the output body 411. It can be understood that the output protrusions 4123 can be arranged in two rows along the axial direction of the output body 411, and these two rows are respectively located near the opposite ends of the output body 411. Of course, the output protrusions 4123 can be arranged in three or more rows along the axial direction of the output body 411, etc.

[0062] See Figure 8 For example, the guide member 412 includes an output piercing 4124. The output body 411 can abut against the mop 12, and the output piercing 4124 can pierce or detach from the mop 12 to release or fix the mop 12. The output piercings 4124 are arranged in one or more rows along the axial direction of the output body 411, and multiple output piercings 4124 in the same row are spaced apart circumferentially along the output body 411. It can be understood that the output piercings 4124 can be arranged in two rows along the axial direction of the output body 411, and these two rows are respectively located near opposite ends of the output body 411. Of course, the output piercings 4124 can be arranged in three or more rows along the axial direction of the output body 411, etc. It is understandable that, given that the output puncture 4124 can directly puncture the mop 12, compared with the embodiment where the output shaft 410 includes the output protrusion 4123, the mop 12 does not need to have a pre-set positioning hole 12a, which can reasonably reduce the manufacturing difficulty and processing cost of the mop 12.

[0063] See Figure 5 In some embodiments, the output mechanism 400 further includes an output baffle 420, which is connected to the frame 100. The output baffle 420 can be fixedly connected or rotatably connected to the frame 100. The output baffle 420 is further away from the discharge device relative to the output shaft 410 along the output direction of the mop 12, and the output shaft 410 and the output baffle 420 abut against the same side of the mop 12. Therefore, by setting the output baffle 420, when the output shaft 410 releases the mop 12 from the discharge mechanism 300, it can effectively prevent the mop 12 released from the discharge mechanism 300 from being wrapped around the output shaft 410, thus preventing the output shaft 410 from failing due to being wrapped around the mop 12, thereby achieving smooth release and output of the mop 12 from the discharge mechanism 300 by the output shaft 410.

[0064] See Figure 9 and Figure 10In some embodiments, when the discharge mechanism 300 includes a discharge roller 310, the discharge mechanism 300 may also include an inner shaft 320. The discharge roller 310 has a receiving cavity 311 and a through hole 312. The receiving cavity 311 is located inside the discharge roller 310, and both ends of the discharge roller 310 are provided with through holes 312. The through holes 312 connect the receiving cavity 311 and the outside, so that the through holes 312 penetrate through the end face of the discharge roller 310. The material roller 230 is used to store and wrap the mop 12. The inner shaft 320 passes through the receiving cavity 311, and both ends of the inner shaft 320 extend out of the through holes 312, so that both ends of the inner shaft 320 are connected to the frame 100. The two ends of the inner shaft 320 can be fixedly connected to the frame 100, so that the inner shaft 320 cannot rotate relative to the frame 100. Therefore, the inner shaft 320 is a fixed shaft. The discharge roller 310 is rotatably sleeved outside the inner shaft 320, allowing the discharge roller 310 to rotate around the central axis of the inner shaft 320, thereby allowing the mop 12 to be wound around the discharge roller 310. Therefore, when the discharge roller 310 rotates relative to the inner shaft 320, the mop 12 can be gradually released from the discharge roller 310.

[0065] See Figure 9 and Figure 10In some embodiments, the discharge mechanism 300 further includes a pre-tightening structure 340. The inner ring 341 of the pre-tightening structure 340 is sleeved on the inner shaft 320, and the outer ring of the pre-tightening structure 340 is fixed to the cavity wall of the receiving cavity 311. When the discharge roller 310 rotates relative to the inner shaft 320, the outer ring of the pre-tightening structure 340 rotates relative to the inner ring 341, thereby forming a certain amount of damping force between the outer ring of the pre-tightening structure 340 and the inner ring 341. This causes the discharge roller 310 and the inner shaft 320 to rotate at a different speed, ultimately allowing the discharge roller 310 to generate a damping effect during its rotation relative to the inner shaft 320. For example, the outer surface of the inner ring 341 of the preload mechanism has protrusions 3411. There can be multiple protrusions 3411, each extending a certain length along the axial direction of the inner shaft 320. These protrusions are spaced apart circumferentially along the inner ring 341, forming a damping groove 3412 between any two protrusions 3411, thus making the inner ring 341 resemble a splined shaft. The outer ring of the preload structure 340 includes an elastic component 342, which is connected to the cavity wall of the receiving cavity 311, and the elastic component 342 elastically abuts against the protrusions 3411. Therefore, when the discharge roller 310 rotates relative to the inner shaft 320, the elastic component 342 can alternately and elastically abut against the protrusion 3411, so that the elastic component 342 can alternately cooperate with different damping grooves 3412. This causes a certain jamming effect during the rotation of the discharge roller 310 relative to the inner shaft 320, so that there is a certain amount of damping force between the discharge roller 310 and the inner shaft 320, thereby achieving the tensioning and flattening effect on the mop 12, and ultimately improving the cleaning effect of the cleaning robot 10.

[0066] See Figure 9 and Figure 10 In some embodiments, there are multiple elastic components 342, which are arranged at intervals along the circumference of the discharge roller 310. By setting multiple elastic components 342, the damping force between the discharge roller 310 and the inner shaft 320 can be reasonably increased, thereby reasonably improving the tensioning and flattening effect on the mop 12.

[0067] In some embodiments, the main unit is provided with a water outlet for spraying water onto the mop 12 wrapped around the cleaning bracket 200 or onto the work surface. For example, the water outlet can supply water to the mop 12, thus giving the mop 12 a certain degree of moisture, thereby improving the cleaning effect of the mop 12 on the work surface. Alternatively, the water outlet can supply water to the work surface, which also allows the mop 12 to clean the work surface while maintaining a certain degree of moisture, further improving the cleaning effect of the mop 12 on the work surface.

[0068] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0069] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
