Description

Technical Field

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

[0002] Floor scrubbers use a sweeping device to collect dust, leaves, and debris from the road surface to a central area below. A suction device then draws this dust, leaves, and debris into a dustbin. Finally, a roller unit at the rear cleans the swept floor. Therefore, the roller unit needs to be periodically removed for cleaning, drying, or replacement to ensure optimal cleaning results.

[0003] Commonly used floor scrubbers are typically large and heavy, thus requiring easy assembly and disassembly of the roller structure. Currently, quick-release methods such as magnetic attraction, knobs, or snap-on latches are commonly used. However, magnetic attraction is not very reliable, especially in commercial environments where rollers are more prone to detachment; knobs are inconvenient for assembly, disassembly, and gripping; and snap-on latches are prone to improper installation and have a short lifespan. Therefore, the roller assembly in current floor scrubbers still suffers from inconvenient assembly and disassembly, and unreliable fixing methods. Summary of the Invention

[0051] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

When a component is referred to as "connected to" another component, it can be directly or indirectly connected to that other component. The terms "upper," "lower," "left," "right," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the purpose of 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 patent. The terms "first" and "second" are used only for the purpose of description and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. "A plurality" means two or more, unless otherwise explicitly specified.

[0053] To illustrate the technical solutions described in this application, the following detailed description is provided in conjunction with specific drawings and embodiments.

[0054] Please refer to the following: Figure 1 and Figure 2 As shown, this application embodiment first provides a roller device 100, which is applied in a cleaning device 200 to clean the ground (sweeping, washing, etc.) during the movement of the cleaning device 200.

[0055] Specifically, please refer to Figure 2 and Figure 3As shown, the roller assembly 100 includes a main support 1 and a roller module 2. The main support 1 is used for fixed installation, for example, fixedly installed on the housing 2001 of the cleaning equipment 200 (see reference). Figure 1 As shown), a roller groove 10 is formed inside the main support 1. Figure 4 and Figure 9 As shown, the roller module 2 includes a roller 21, a locking component 22, and a pop-out component 23. The locking component 22 is connected to the roller 21 and has a first position and a second position. When the locking component 22 is in the first position, it is locked together with the main support 1. At this time, the locking component 22 and the main support 1 remain fixed, and the roller 21 is also axially fixed to the main support 1. The roller 21 is located in the roller groove 10 and cannot slide out of the roller groove 10. When the locking component 22 is in the second position, the lock between it and the main support 1 is released, and it is released from the main support 1. The locking component 22, together with the roller 21, can slide axially relative to the main support 1, so that the roller 21 can slide out of the roller groove 10. The pop-out component 23 is used to provide a force for the roller 21 to slide out of the roller groove 10. That is, when the locking component 22 is in the second position, the force provided by the pop-out component 23 can make the roller 21 and the locking component 22 move outward automatically, thus realizing the disassembly of the roller module 2 from the main support 1.

[0056] Before the roller 21 slides outward from the roller groove 10, the user can manually keep the locking component 22 in the second position. The pop-out component 23 provides an outward force to the roller 21. After the roller 21 slides outward a certain distance, a distance is also formed between the locking component 22 and the main support 1. At this time, the locking component 22 and the main support 1 cannot form a lock. After the roller 21 has been cleaned, dried, or replaced, the user can push the roller 21 into the roller groove 10. During this pushing process, after the roller 21 is pushed into place, a locking connection is formed between the locking component 22 and the main support 1. At this time, the locking component 22 applies an inward force to the pop-out component 23.

[0057] The roller device 100 provided in this application embodiment includes a roller 21, a locking component 22, and a pop-out component 23 in its roller module 2. The locking component 22 has a first position locked to the main support 1 and a second position released from the main support 1. The pop-out component 23 is used to provide a force for the roller 21 to slide out of the roller groove 10. Therefore, when the user moves the locking component 22 to the second position, the roller 21 can be automatically moved out of the roller groove 10 under the action of the pop-out component 23. When the user pushes the roller 21 into the roller groove 10, moving the locking component 22 to the first position will keep the roller 21 in the roller groove 10. The roller device 100 is easy to remove and install, and the operation is labor-saving. Moreover, the locking method of the roller 21 is more reliable, effectively avoiding the problem of the roller 21 sliding out when not in use, and improving the user experience.

[0058] It should be noted that the terms "inner" and "outer" used in the above description are based on the space of the roller groove 10. That is, "inner" refers to the inside of the roller groove 10, and "outer" refers to the outside of the roller groove 10.

[0059] Furthermore, it should be noted that the roller 21 has a central axis, which it needs to rotate around during use. In the following description, unless otherwise specified, "axial," "circumferential," and "radial" refer to the axial, radial, and circumferential directions of the roller 21. That is, the axial direction is the direction parallel to the central axis of the roller 21, the circumferential direction is the direction of the circumference around the central axis of the roller 21, and the radial direction is the direction of the radius of a circle perpendicular to the central axis of the roller 21 with any point on the central axis of the roller 21 as its center.

[0060] Please see Figure 3 As shown, the roller groove 10 in the main support 1 is adapted to the shape of the roller 21, and the main support 1 is provided with two openings communicating with the roller groove 10. One opening is located at one axial end (outer end) of the main support 1, which is connected to one axial end (outer end) of the roller groove 10, for the roller 21 to slide out and be pushed in. The other opening is opened on the side wall of the main support 1 and extends along the axial direction of the main support 1, for allowing the roller 21 to contact the ground during the operation of the cleaning equipment 200, thereby cleaning the ground.

[0061] It should also be noted that the main support 1 is used to support the aforementioned roller 21, locking component 22, ejector component 23, etc. It can be a component that is independent of and assembled with the housing 2001. When the roller device 100 needs to be installed, it can be connected and fixed to the housing 2001 via the main support 1. Alternatively, the main support 1 can be a part of the housing 2001, such as being integrally formed with at least a part of the housing 2001. When the roller device 100 needs to be installed, the roller 21, locking component 22, ejector component 23, etc., are assembled onto the main support 1 of the housing 2001. In specific applications, the form of the main support 1 can be designed according to product requirements and is not particularly limited here.

[0062] Please see Figure 8 and Figure 9 As shown, in one embodiment, the locking assembly 22 includes a locking bracket 221, a button 222, and a swing arm gripper 223. The button 222 is mounted on the locking bracket 221 and is movable along the axial direction of the roller 21. The swing arm gripper 223 is rotatably mounted on the locking bracket 221, with its rotation axis perpendicular to the axial direction of the roller 21. When the button 222 moves toward the roller 21 (inward), it can push the swing arm gripper 223 to rotate. After rotating, the swing arm gripper 223 disengages from the main bracket 1, i.e., reaches the second position. The ejector assembly 23 is disposed between the locking bracket 221 and the main bracket 1, and is used to provide an outward pushing force to the locking bracket 221.

[0063] In other words, when the user presses the button 222 inward, the swing arm gripper 223 can disengage from the main support 1. Then, the pop-out component 23 pushes the locking bracket 221 outward. As long as the locking bracket 221 moves outward a certain distance, the swing arm gripper 223 will create a certain distance between itself and the main support 1. At this time, even if the swing arm gripper 223 rotates in the opposite direction and returns to the first position, it can no longer lock with the main support 1, and the roller 21 is in a free state. Then, the user can hold the locking bracket 221 to continue to pull out the locking component 22 and the inner roller 21.

[0064] When the user holds the locking bracket 221 and pushes the roller 21 inward, the swing arm gripper 223 will not lock with the main bracket 1 during the pushing process; until it is pushed in, that is, when the distance between the swing arm gripper 223 and the main bracket 1 is the smallest, the swing arm gripper 223 is in the first position and can automatically lock with the main bracket 1, thus completing the assembly of the roller module 2.

[0065] It is understandable that the aforementioned swing arm gripper 223 locks and unlocks with the main support 1 during rotation. During its rotation, there is a critical point as the dividing point between the first position and the second position. That is, the locking and / or unlocking can only be achieved when the rotation reaches a certain degree. Each of the first position and the second position can be a definite position point, or it can be a combination of a series of position points.

[0066] Specifically, please refer to Figure 9 and Figure 10 As shown, in one embodiment, the locking bracket 221 includes a first bracket portion 2211 and a second bracket portion 2212. The second bracket portion 2212 is axially disposed between the first bracket portion 2211 and the roller 21, and the first bracket portion 2211 and the second bracket portion 2212 are fixedly connected. A button hole 22110 is formed on the first bracket portion 2211. The end of the button member 222 facing the second bracket portion 2212 is outwardly expanded to form a larger diameter retaining edge 2221. The outer diameter of the retaining edge 2221 is larger than the outer diameter of the button hole 22110. Thus, the retaining edge 2221 of the button member 222 is blocked behind the button hole 22110, and the retaining edge 2221 cannot enter the button hole 22110, while the outer end of the button member 222 is disposed inside the button hole 22110. The purpose of this design is twofold: firstly, the button 222 is confined between the first support portion 2211 and the second support portion 2212, preventing it from detaching from the locking bracket 221; the button 222 can only be removed by disassembling the first support portion 2211 and the second support portion 2212. Secondly, it allows the user to touch the button 222. The connection between the button 222 and the locking bracket 221 is relatively simple.

[0067] Please see Figures 2 to 4 as well as Figure 9 As shown, some indicator information can be provided on the outer surface of the button 222 and / or the outer surface of the first support portion 2211 to prompt the user to press the button 222 inward to pull out the roller 21. Specifically, the indicator information can be text, such as "Open" or "Press to pull out" on the outer surface of the button 222, or "Close" on the outer surface of the first support portion 2211; or the indicator information can be graphics, such as finger patterns or arrow patterns on the outer surface of the button 222. In specific applications, the indicator method can be designed according to product requirements, user habits, etc., and will not be elaborated further.

[0068] Please see Figure 9As shown, in one embodiment, the swing arm gripper 223 includes a swing arm body 2231 and a first elastic member 2232. Two swing arms 22311 are formed on the swing arm body 2231. One swing arm 22311 abuts against the inner surface of the button 222, and the other swing arm 22311 abuts against the inner surface of the main support 1 to form a lock with the main support 1. The first elastic member 2232 is disposed between the swing arm body 2231 and the locking bracket 221, and is used to provide force to the swing arm body 2231 to restore its rotation. Therefore, when the button 222 moves inward, the inner surface of the button 222 pushes the first swing arm 22311 to rotate, and the second swing arm 22311 rotates accordingly. After the second swing arm 22311 rotates, its end will not be located inside the main support 1, so the main support 1 will not affect the outward movement of the swing arm gripper 223. That is, the locking assembly 22 is allowed to move outward as a whole at this time. When the locking assembly 22 moves outward as a whole, the force applied by the button 222 to the first swing arm 22311 is released. Under the action of the first elastic member 2232, the swing arm gripper 223 rotates in the opposite direction (outward) and returns to the first position.

[0069] The first elastic element 2232 can be a torsion spring, used to provide a rotational force to the swing arm body 2231. Not limited thereto, in other alternative embodiments, the first elastic element 2232 can be a tension spring, a leaf spring, or other structural components capable of pushing the swing arm body 2231 to return to rotation.

[0070] In one embodiment, the swing arm gripper 223 further includes a first connecting shaft 2233. A first through hole (not shown) is formed on the swing arm body 2231, and a second through hole is provided on the locking bracket 221. The first connecting shaft 2233 is disposed in the first through hole and the second through hole, so that the swing arm body 2231 is installed on the locking bracket 221 through the first connecting shaft 2233.

[0071] Specifically, in this embodiment, the second through hole can be provided on the first support portion 2211. Of course, in other alternative embodiments, depending on the size configuration, the second through hole can also be provided on the second support portion 2212 if permitted, or it can be formed on both the first support portion 2211 and the second support portion 2212. This is not particularly limited here.

[0072] Specifically, such as Figure 9 and Figure 10As shown, in one embodiment, the swing arm gripper 223 further includes a first abutment 2234. One end of the first connecting shaft 2233 forms a first abutment portion 22331 with a larger diameter. The first connecting shaft 2233 passes through the second through hole and the first through hole and extends out. The first abutment 2234 is disposed at the other end of the first connecting shaft 2233 to restrict the first connecting shaft 2233 in the second through hole and the first through hole, so as to prevent the first connecting shaft 2233 from disengaging from the first through hole and the second through hole along its own central axis direction.

[0073] The first abutment 2234 can be a retaining ring, with an annular groove (not shown) formed on the other end of the first connecting shaft 2233 to engage with the retaining ring. Alternatively, the first abutment 2234 can be a pin, with a through hole formed on the other end of the first connecting shaft 2233, into which the pin is inserted. In other alternative embodiments, the first abutment 2234 can have many other available forms, which will not be described in detail here.

[0074] In this embodiment, there are two swing arm grippers 223, which are respectively located on opposite sides of the locking bracket 221. The two swing arm grippers 223 are used to clamp and lock the main bracket 1 from opposite sides of the locking bracket 221, so that the locking connection between the locking component 22 and the main bracket 1 is more balanced and stable.

[0075] In addition to the above, in other alternative embodiments, the number of swing arm grippers 223 can be more, such as three or four, and can be distributed on opposite sides of the locking bracket 221.

[0076] Specifically, please refer to Figure 9 and Figure 10 As shown, each side of the first support portion 2211 is provided with two second through holes, the first connecting shaft 2233 passes through the two second through holes and the first through hole, and the swing arm body 2231 is located between the two second through holes. The purpose of this arrangement is to allow the swing arm gripper 223 to be more stably mounted on the locking bracket 221.

[0077] When assembling the swing arm gripper 223 onto the locking bracket 221, firstly, the first elastic member 2232 is assembled into the first through hole, the swing arm body 2231 and the first elastic member 2232 are placed between the two second through holes of the first bracket part 2211, the first connecting shaft 2233 is inserted into the second through hole, the first through hole and the second through hole in sequence, and then the first abutment 2234 is connected to the other end of the first connecting shaft 2233.

[0078] Not limited to the above, in other alternative embodiments, the opposite sides of the swing arm body 2231 may be provided with protruding shafts (not shown), which are respectively inserted into two second through holes, and the first elastic element 2232 is disposed between the shaft and the locking bracket 221. In this way, the automatic return of the swing arm body 2231 can also be realized, and the first connecting shaft 2233 mentioned above can be eliminated.

[0079] Next, please refer to Figure 12 As shown, in one embodiment, the pop-out component 23 includes a second elastic element 232 and a cap 231. The cap 231 is slidably connected to the locking component 22 along the axial direction of the roller 21, specifically its locking bracket 221. The second elastic element 232 is elastically compressed between the cap 231 and the locking component 22.

[0080] Specifically, such as Figure 8 and Figure 12 As shown, a groove 22121 is recessed on the inner surface of the second support portion 2212. The inner wall of the groove 22121, on the side away from the roller 21, expands radially outward to form a stepped surface 22122. An undercut portion 2312 is formed at the end of the cap 231 facing the locking support 221, extending radially outward. A second elastic member 232 is disposed within the cap 231 and the groove 22121. During the sliding of the cap 231 along the axial direction of the roller 21, the second elastic member 232 remains compressed. The degree of compression of the second elastic member 232 is minimal when the undercut portion 2312 abuts against the stepped surface 22122.

[0081] When the locking bracket 221 and the main bracket 1 are locked together, the distance between them is at its minimum, and the cap 231 is pushed outward by the main bracket 1, resulting in the maximum compression of the second elastic element 232. When the lock between the locking bracket 221 and the main bracket 1 is released, the outward thrust provided by the second elastic element 232 acts on the locking bracket 221, thereby allowing the locking bracket 221 to move outward. At the same time, the second elastic element 232 moves outward with the locking bracket 221.

[0082] Please see Figure 12 As shown, the end of the cap 231 facing the locking bracket 221 includes a plurality of claws 2311 spaced apart along its own circumference, and the end of each claw 2311 forms the aforementioned undercut portion 2312. This arrangement is intended to allow the end of the cap 231 facing the locking bracket 221 to deform radially. Therefore, when assembling the cap 231 into the slot 22121, simply pressing the plurality of claws 2311 radially inwards respectively easily pushes the cap 231 into the slot and onto the outer side of the stepped surface 22122, thus confining a portion of the cap 231 within the slot 22121.

[0083] Of course, not limited to the above description, in other alternative embodiments, the pop-out component 23 can be disposed on the main support 1 and provide an outward thrust to the locking support 221. When the lock between the locking support 221 and the main support 1 is released, the elastic component does not move with the locking support 221. For example, the slot 22121 is formed on the outer surface of the main support 1, and when the cap 231 moves inward, it compresses the second elastic element 232, which is equivalent to a 180° rotation of the cap 231. The specific configuration can be referred to the above description. Of course, the pop-out component 23 can have many other implementations, which will not be listed here.

[0084] Please see Figure 9 As shown, in one embodiment, there can be two pop-out components 23, and the line connecting the two pop-out components 23 intersects the axial direction of the roller 21. The purpose of this arrangement is that the pop-out components 23 are distributed on opposite sides of the roller 21, providing a relatively balanced thrust to the locking bracket 221, allowing the locking bracket 221 to pop out stably. Of course, in other alternative embodiments, the number of pop-out components 23 can be other values, but they can be evenly distributed circumferentially on the roller 21.

[0085] Please continue reading. Figure 8 As shown, in one embodiment, a plurality of guide holes 22123 are formed on the inner surface of the second support portion 2212, and a plurality of first guide posts 313 are formed on the main support 1 (please refer to the reference). Figure 5 and Figure 6 As shown (details described below), the guide hole 22123 and the first guide post 313 are arranged along the axial direction of the roller 21. When the locking bracket 221 is relatively close to the main bracket 1, the first guide post 313 can slide within the guide hole 22123 to provide a certain guiding effect for the locking bracket 221, so that the locking bracket 221 does not deviate when it pops out and when it is pushed in. This ensures that the initial stage of the popping process and the final stage of the pushing process of the roller 21 are relatively smooth, making it easier to disengage from the main bracket 1 and re-lock with the main bracket 1. The guide hole 22123 and the first guide post 313 can be evenly distributed in the circumferential direction of the roller 21 to ensure the balance of the guide.

[0086] Not limited to the above, in other alternative embodiments, the guide hole 22123 may be formed on the outer surface of the main support 1, and the first guide post 313 may be formed on the second support portion 2212.

[0087] In this embodiment, two slots 22121 and two guide holes 22123 are formed on the second support portion 2212, and the two slots 22121 and the two guide holes 22123 are diagonally distributed.

[0088] Please see Figures 2 to 4As shown, in one embodiment, the roller device 100 further includes an anti-misfire triggering module 3. The anti-misfire triggering module 3 is mounted on the main support 1 and has a third position and a fourth position. When the anti-misfire triggering module 3 is in the third position, it can block the locking component 22 and the roller 21, so that the locking component 22 and the roller 21 cannot be pulled out. When the anti-misfire triggering module 3 is in the fourth position, its blocking of the locking component 22 is released, and the locking component 22 and the roller 21 can be pulled out.

[0089] Specifically, please refer to Figure 5 and Figure 6 As shown, the anti-misfire triggering module 3 includes an anti-misfire triggering bracket 31, a toggle block 32, and a third elastic element 33. The anti-misfire triggering bracket 31 is fixed on the main bracket 1, specifically on the outer end face of the main bracket 1. The toggle block 32 is slidably disposed on the anti-misfire triggering bracket 31. The third elastic element 33 is disposed between the anti-misfire triggering bracket 31 and the toggle block 32, and is used to provide a force to the toggle block 32 to move towards the roller 21. That is, the user can apply force to the toggle block 32 with their hand, causing the toggle block 32 to move away from the roller 21 and reach the fourth position. At this time, the toggle block 32 is away from the roller 21 and the locking component 22, and the toggle block 32 will not block the locking component 22. Conversely, when the toggle block 32 moves towards the roller 21, it can reach a position that can block the locking component 22, that is, the third position.

[0090] When the toggle block 32 is in the third position, its lower end is located outside the locking bracket 221, thus preventing the locking bracket 221 from moving outward. (See also...) Figure 10 As shown.

[0091] Similarly, it can be understood that the aforementioned lever 32 locks and unlocks with the locking bracket 221 during its movement. There is also a critical point during its movement as the dividing point between the third and fourth positions. That is, the locking and / or unlocking can only be achieved when the movement reaches a certain extent. Each of the third and fourth positions can be a definite position point or not a definite position point, but a combination of a series of position points.

[0092] In practical applications, the sliding direction of the lever 32 is perpendicular to the axial direction of the roller 21. For example, the lever 32 is located on the side of the roller 21 away from the ground, and it can slide up and down, reaching the fourth position upwards and the third position downwards. The third elastic element 33 is arranged along the sliding direction of the lever 32 and is compressed.

[0093] The third elastic element 33 ensures that the locking component 22 is only released when the user actively applies force to the lever 32. When the user cancels the operation on the lever 32, the lever 32 automatically returns to its third position under the pushing force of the third elastic element 33. This effectively adds another safety barrier to the locking component 22, preventing the roller 21 from accidentally popping out during use of the cleaning equipment 200 due to vibration or bumps, and also preventing accidental operation by children in complex environments such as commercial environments, thus improving the safety of the roller device 100.

[0094] Please see Figure 5 and Figure 6 As shown, the anti-accidental triggering bracket 31 has a slot 310 adapted to the roller 21, through which the roller 21 passes. This allows the anti-accidental triggering bracket 31 to be generally positioned between the locking bracket 221 and the main bracket 1. It should be noted that the anti-accidental triggering bracket 31 and the main bracket 1 can be integrally formed or can be separate structural components formed and connected separately.

[0095] It should also be noted that, since the anti-accidental triggering bracket 31 is located on the outside of the main bracket 1 and is fixedly connected to the main bracket 1, the anti-accidental triggering bracket 31 can essentially be considered part of the main bracket 1. Therefore, the connection and locking relationship between the locking component 22 and the main bracket 1 mentioned above can be replaced by the connection and locking relationship between the locking component 22 and the anti-accidental triggering bracket 31. For example, please refer to... Figure 5 and Figure 6 As shown, the first guide post 313 can be formed on the outer surface of the anti-mis-trigger bracket 31 at this time.

[0096] Please see Figure 6 and Figure 10 As shown, the lower end of the lever 32 forms a first guide surface 320, which gradually slopes towards the roller 21 from the outside to the inside. Please refer to [link / reference]. Figure 8 and Figure 10As shown, a second guide surface 22111 is formed on the upper end of the locking bracket 221. The second guide surface 22111 gradually tilts away from the lever 32 in the direction from the outside to the inside. The purpose of this setting is that when the user needs to reassemble the roller 21 into the roller groove 10, the locking component 22 can be pushed inward directly, and the second guide surface 22111 slides against the first guide surface 320. As the locking component 22 moves, the lever 32 is pushed upward by the locking bracket 221, and the third elastic element 33 is gradually compressed. The lowermost end of the lever 32 gradually slides to the uppermost end of the second guide surface 22111. Until the roller 21 is pushed into place, the lowermost end of the lever 32 passes the second guide surface 22111. Under the downward force provided by the third elastic element 33, the lowermost end of the lever 32 automatically moves downward. At this time, the lowermost end of the lever 32 is located on the outer surface of the locking bracket 221, thereby blocking the locking bracket 221. Figure 1 As shown.

[0097] In one embodiment, see Figure 5 As shown, the anti-accidental trigger bracket 31 has a downward-opening mounting groove 311, and the toggle block 32 is disposed in the mounting groove 311 and slides within the mounting groove 311. Of course, the outer side of the mounting groove 311 is also open, so that a part of the outer surface of the toggle block 32 is exposed for the user to operate by hand.

[0098] Please see Figure 6 and Figure 10 As shown, a mounting mating portion 322 is formed on the lever 32. This mounting mating portion 322 has a mounting mating surface 3220. The mounting mating surface 3220 gradually slopes downward in the direction away from the lever 32 and towards the anti-misfire bracket 31, that is, it slopes towards the opening side of the mounting groove 311 or towards the roller 21. Please refer to [link / reference]. Figure 5 As shown, the anti-misfire bracket 31 is provided with a mating groove 312 for accommodating the mounting mating surface 3220. The purpose of this design is that when the lever 32 is assembled into the mounting groove 311, the lever 32 is inserted through the opening on the lower side of the mounting groove 311 and pushed upwards. Due to the mounting mating surface 3220, although the mounting mating part 322 is pressed against the anti-misfire bracket 31, it can still continue to slide upwards until it is fully inserted into the mating groove 312. The height of the mating groove 312 (its dimension in the sliding direction of the lever 32) is greater than the height of the mounting mating part 322, allowing the mounting mating part 322 to slide within the mating groove 312 without easily disengaging.

[0099] In addition to the above, in other alternative embodiments, the mounting mating part 322 may be formed on the anti-misfire bracket 31, the mating groove 312 may be formed on the toggle block 32, and correspondingly, the mounting mating surface 3220 is gradually inclined away from the roller 21 in the direction from the toggle block 32 to the anti-misfire bracket 31.

[0100] In addition, please see Figure 5 , Figure 6 and Figure 11 As shown, in one embodiment, the third elastic element 33 is a spring, and the lever 32 is also provided with a second guide post 321, which extends along the sliding direction of the lever 32. A portion of the spring is sleeved on the second guide post 321. The second guide post 321 is used to provide a certain guiding effect for the compression of the spring during the upward sliding of the lever 32 and compression of the spring, so as to avoid the problem of spring torsion affecting the automatic return of the lever 32.

[0101] Not limited to the above, in other alternative embodiments, the second guide post 321 may also be disposed on the anti-false trigger bracket 31. Further details will not be elaborated further.

[0102] Please see Figure 3 , Figure 4 and Figure 7 As shown, in one embodiment, the roller module 2 further includes a drive module 4, which is fixedly mounted on the main support 1 and located on the side of the roller 21 opposite to the locking component 22, for driving the roller 21 to rotate. The drive module 4 and the locking component 22 are located on opposite axial sides of the roller 21, which can avoid mutual interference between them. Of course, it is immediately apparent that the drive module 4 needs to be connected to a power source (not shown). When the roller 21 and the locking component 22 are pulled outward, the drive module 4 is disconnected from the roller 21, and the drive module 4 remains on the housing 2001.

[0103] Specifically, such as Figure 7 and Figure 11 As shown, in one embodiment, the drive module 4 specifically includes a motor 41, a first gear 42, a timing belt 43, a second gear 44, and a first end cover 45. The motor 41 is fixedly mounted on the main support 1. The first gear 42 is coaxially connected to the output shaft of the motor 41. The second gear 44 is mounted on the main support 1 and connected to the first gear 42 via the timing belt 43. The first end cover 45 is coaxially connected to the second gear 44 and is located on the side of the second gear 44 facing the roller 21. A concave-convex structure is formed on the outer circumferential surface of the first end cover 45, which is adapted to the shape of the inner wall of the roller 21. Therefore, when the motor 41 rotates, the first gear 42, the timing belt 43, the second gear 44, and the first end cover 45 rotate sequentially, thereby causing the first end cover 45 to drive the roller 21 to rotate. Furthermore, the concave-convex structure on the outer circumferential surface of the first end cover 45 does not affect the outward movement of the roller 21 along the axial direction.

[0104] Not limited to this, in other alternative embodiments, the drive module 4 may have other configurations depending on the product design requirements and the space allowed on the housing 2001, which will not be described in detail here.

[0105] Please see Figure 7 and Figure 11 As shown, in one embodiment, the drive module 4 may further include a motor bracket 46, on which the motor 41, the first gear 42, the second gear 44, etc., can all be mounted. The motor bracket 46 is fixedly connected to the main bracket 1, or the motor bracket 46 and the main bracket 1 are integrally formed. The specific form of the motor bracket 46 is not particularly limited; for example, it may include two relatively connected parts. Please refer to [reference needed]. Figure 7 The third support portion 461 and the fourth support portion 462 of the motor bracket 461 and 462 respectively hold the motor 41, the first gear 42, the timing belt 43, and the second gear 44. The first end cap 45 extends from the motor bracket 46 and connects to the roller 21. Of course, depending on product requirements and the space arrangement of the housing 2001, the motor bracket 46 can have other configurations, which will not be listed here.

[0106] Please see Figure 9 As shown, in one embodiment, the roller device 100 further includes a connecting component 24 for connecting between the roller 21 and the locking component 22, so that the roller 21 can rotate relative to the locking component 22 in the circumferential direction while maintaining an axial connection with the locking component 22.

[0107] Specifically, such as Figure 9 As shown, the connecting assembly 24 includes a bearing 243, a second end cap 241, and a second connecting shaft 242. A portion of the second end cap 241 is connected to the inner wall of the roller 21, and the two are fixedly connected in the circumferential and axial directions. The second connecting shaft 242 passes through the second end cap 241 and is connected to the locking assembly 22. The bearing 243 is disposed between the second connecting shaft 242 and the locking assembly 22 so that the second connecting shaft 242 can rotate together with the roller 21.

[0108] Specifically, please refer to 9 and Figure 10As shown, the inner end of the second connecting shaft 242 forms a flat portion 2421, and the second end cap 241 forms a flat groove (not shown) that matches the shape of the flat portion 2421. After the second connecting shaft 242 passes through the second end cap 241, its flat portion 2421 is located in the flat groove, thus keeping the second connecting shaft 242 and the second end cap 241 relatively fixed in the circumferential direction. The second connecting shaft 242 continues to pass outward through the shaft hole 22120 on the second bracket portion 2212, and the bearing 243 is located in the shaft hole 22120. A second abutment 244 is provided on the portion of the second connecting shaft 242 located on the outside of the second bracket portion 2212 to keep the second connecting shaft 242 axially connected to the locking bracket 221.

[0109] The second stop 244 can be a snap ring, with a matching annular groove (not shown) on the second connecting shaft 242; or, the second stop 244 can be a pin, etc., which will not be described in detail here.

[0110] Please see Figures 9 to 11 As shown, the roller 21 may include a roller base 211 and a cleaning outer layer 212 wrapped around the roller base 211. The two ends of the roller base 211 are respectively connected to the first end cap 45 and the second end cap 241. The cleaning outer layer 212 rotates with the roller base 211 and performs sweeping, washing, etc., on the floor. The cleaning outer layer 212 can be a mop, which sprays water to clean the floor, or it can be a roller brush, which sweeps the floor. The cleaning outer layer 212 may be detachable from the roller base 211.

[0111] Please see Figure 1 As shown, another objective of this application embodiment is to provide a cleaning device 200, including a housing 2001 and a roller device 100 as described in the above embodiments. The main support 1 of the roller device 100 is fixedly connected to the housing 2001. The main support 1 and the housing 2001 are either separately formed and connected or integrally formed.

[0112] The cleaning device 200 provided in this application embodiment has a roller device 100 in which the roller module 2 is easy to remove and install, and the operation is labor-saving. The roller 21 is reliably locked, which effectively prevents the roller 21 from sliding out when not in use, and provides a good user experience.

[0113] The cleaning equipment 200 can be a mobile floor scrubber, a mopping robot, or a handheld floor scrubber, etc. Any cleaning device that requires the roller device 100 to clean or sweep the floor can be used here.

[0114] For example, please see Figure 1As shown, taking the cleaning equipment 200 as a mobile floor scrubber as an example, the cleaning equipment 200 also includes a sweeping device 2002, which is usually set on both sides of the lower part of the machine body housing 2001. It is used to sweep the garbage on the road surface inward, and then suck the collected garbage away by the suction device (not shown). Then, the roller device 100 cleans the swept ground.

[0115] When it is necessary to clean, dry, or replace the roller 21, the user should follow the steps below:

[0116] Use your first finger to flick the lever 32 upwards, and use your second finger to press the button 222 inwards. Release your second finger to release the pressure on the button 222, and the roller 21 will pop out automatically. Release your first finger to release the flicking of the lever 32, and use the locking bracket 221 to pull out the roller 21.

[0117] Push the roller 21 toward the roller groove 10 until the roller 21 reaches the innermost position and is connected to the drive module 4. The anti-mis-trigger module 3 automatically blocks the locking bracket 221.

[0118] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
