[0025] This application provides a roller brush device 100 for cleaning equipment. The cleaning equipment can be a floor scrubber, a sweeper, or more, but is not limited to these. The following description uses a floor scrubber as an example.

[0026] Please refer to Figures 1 to 4 This application provides a cleaning device, which includes a roller brush device 100 and a roller brush motor (not shown in the figure). The roller brush device 100 includes a housing support 10 and a roller brush 20. The roller brush 20 is rotatably connected to the housing support 10. The roller brush motor is connected inside the housing support 10 and drives the roller brush 20 to rotate at high speed, thereby breaking down dirt on the ground through physical friction.

[0027] The roller brush device 100 also includes a hair breaking assembly 30, which includes a contact head 31 and a drive assembly 32. When the roller brush is not in operation, the drive assembly 32 responds to a drive signal to drive the contact head 31 from the first end 21 of the roller brush 20 along the axial direction of the roller brush 20 to the second end 22 of the roller brush 20 in a manner that conforms to the surface of the roller brush 20, so that the contact head 31 breaks off the hairs it contacts on its movement path.

[0028] In this context, the roller brush 20 is in a non-working state, which can be understood as the roller brush motor stopping its drive and the roller brush 20 being in a static state. The roller brush 20 being static can occur during the operation of the floor scrubber by pausing the machine's operation, and then by pressing the bristle-breaking button on the floor scrubber to output a drive signal, causing the drive component 32 to respond and drive the contact head 31. Alternatively, the roller brush 20 can be in a static state when the floor scrubber is in self-cleaning mode, which has a preset bristle-breaking program, and the drive component 32 executes the command signals in the bristle-breaking program.

[0029] Additionally, when the drive assembly 32 responds to the drive signal, the roller brush motor also responds to the drive signal simultaneously, causing the roller brush 20 to stop rotating. This can be understood as the roller brush 20 stopping its rotation when the hair-breaking assembly 30 is needed to break the hairs on it.

[0030] Regardless of the current state of the floor scrubber, before starting the drive assembly 32 to drive the contact head 31, the roller brush device needs to determine whether the roller brush 20 is static. If the roller brush 20 is static, the drive assembly 32 can be used to drive the contact head 31. If the roller brush 20 is not static, the roller brush 20 needs to be stopped first before the drive assembly 32 can be used to drive the contact head 31.

[0031] By moving the contact head 31 in a manner that adheres to the surface of the roller brush 20, the hair wrapped around the roller brush 20 can be completely broken off, so that the broken hair can be sucked away by the vacuum component of the floor scrubber, thereby improving the removal effect of the hair wrapped around the roller brush 20.

[0032] In an optional embodiment, the surface of the roller brush 20 is fitted with flexible bristles, and the contact head 31 moves in a manner that conforms to the surface of the roller brush 20. This allows for the breaking off of both tightly wrapped and loosely wrapped hairs on the roller brush 20, improving the thoroughness of hair removal and further enhancing the hair removal effect. The specific material of the bristles is not specifically limited in this embodiment and can be set according to requirements.

[0033] In an alternative embodiment, the contact head 31 is a heating element configured to burn off hair wrapped around the roller brush 20. This can be understood as the heating element heating itself to a temperature sufficient to burn off the hair without damaging the bristles or the surface of the roller brush 20.

[0034] In another alternative embodiment, the contact head 31 is a cutter 311, which is configured to cut hair wrapped around the roller brush 20.

[0035] Furthermore, a hook-shaped structure 3112 is formed at the end of the cutting blade 311. The hook-shaped structure 3112 bends toward the direction of movement of the cutting blade 311 so as to hook up the hair wrapped around the roller brush 20 so that the hair can be cut by the cutting blade 311, thereby improving the cutting efficiency.

[0036] In one alternative embodiment, please refer to Figure 4The drive assembly 32 includes a first drive member 321, a first rotating shaft 322, and a first connector 323. The first rotating shaft 322 is connected to the first drive member 321 and rotates under the drive of the first drive member 321. One end of the first connector 323 is connected to the first rotating shaft 322, and the other end is connected to the contact head 31. The first connector 323 is wound around the first rotating shaft 322 under the action of the first drive member 321 so as to drive the contact head 31 to move from the first end 21 of the roller brush 20 toward the second end 22.

[0037] The first driving component 321 is preferably a motor, but is not limited to this. The first connecting component 323 is a wire rope or a nylon rope, but is not limited to this.

[0038] This can be understood as follows: the first rotating shaft 322 rotates under the driving action of the first driving member 321 and winds the first connecting member 323, thereby enabling the first connecting member 323 to pull the contact head 31 from the first end 21 of the roller brush 20 toward the second end 22, and to break off the hair wrapped on the roller brush 20.

[0039] In this embodiment, the contact head 31 is moved from the first end 21 to the second end 22 of the roller brush 20 by the cooperation of the first rotating shaft 322 and the first connecting member 323. This structure is simple and can completely cut off the hair wrapped around the surface of the roller brush 20.

[0040] In one alternative embodiment, please refer to Figure 4 , Figure 5 and Figure 8 The bristle breaking assembly 30 also includes a mounting bracket 33 and a slider 34. The mounting bracket 33 is connected to the housing bracket 10 and has a slide rail 331 extending along a first direction, which is the axial direction of the roller brush 20. The slider 34 is slidably connected to the slide rail 331. A contact head 31 is connected to the slider 34, and the slider 34 is connected to the drive assembly 32. Under the driving action of the drive assembly 32, the contact head 31 follows the slider 34 along the slide rail 331 from one end of the roller brush 20 to the other end.

[0041] The slider 34 is provided with a groove 341. The slider 34 is embedded in the mounting bracket 33 through the groove 341. The groove 341 is adapted to the slide rail 331. The sliding connection between the slider 34 and the slide rail 331 can improve the smoothness of the contact head 31 during movement. At the same time, the sliding of the slider 34 embedded in the mounting bracket 33 can improve the stability of the contact head 31 during movement.

[0042] When the contact head 31 acts on the bristles, the contact head 31 is subjected to force and the force is transmitted to the slider 34. The slider 34 is embedded in the mounting bracket 33 through the groove 341, which can further transmit the force to the mounting bracket 33, thereby ensuring the stability and directional consistency of the contact head 31 during the movement process and ensuring the hair cutting effect.

[0043] In one alternative embodiment, please refer to Figure 5 The cutting blade 311 is detachably mounted on the slider 34, which serves as the mounting base for the cutting blade 311 to ensure its stability during the cutting process. Since the cutting blade 311 may wear out after prolonged use, it is replaced to maintain the cutting effect. The connection method between the cutting blade 311 and the slider 34 is not specifically limited in this embodiment; exemplary methods include pin connection and snap-fit ​​connection.

[0044] In one alternative embodiment, please refer to Figure 5 The hair-breaking assembly 30 also includes a reset elastic element 35. One end of the reset elastic element 35 is connected to the slider 34, and the other end is connected to the end of the mounting bracket 33. When the slider 34 moves from the first end 21 to the second end 22 of the roller brush 20, the slider 34 can be reset under the action of the reset elastic element 35. That is, the slider 34 moves from the second end 22 to the first end 21 under the action of the reset elastic element 35, realizing the reciprocating motion of the contact head 31.

[0045] The reset elastic element 35 is preferably a compression spring 352, but it is not limited to this.

[0046] Furthermore, the cutting blade 311 is configured to cut the hair wrapped around the roller brush 20. The cutting blade 311 has blades 3111 on both sides in the first direction. Having blades 3111 on both sides of the cutting blade 311 can further improve the cutting effect of the cutting blade 311 on the hair.

[0047] In an optional embodiment, the roller brush device 100 further includes a guide shaft 351, which is connected to the housing support 10. A compression spring 352 is fitted onto the guide shaft 351 and can push the compression spring 352 to deform during the movement of the slider 34. The guide shaft 351 can not only guide the compression spring 352, but also guide the movement direction of the slider 34, ensuring the consistency of the movement direction and force direction of the contact head 31.

[0048] Figure 5 The diagram shows the state of the compressed spring 352 when the contact head 31 is located at the first end 21 of the roller brush 20. Figure 6 , Figure 7 and Figure 8 The diagram shows the state of the compressed spring 352 when the contact head 31 is located at the second end 22 of the roller brush 20.

[0049] In one alternative embodiment, please refer to Figure 9 The drive assembly 32 also includes a second drive member 324, a second rotating shaft 325, and a second connecting member 326. The second drive member 324 is preferably a motor, but is not limited to this. The second connecting member 326 is made of the same material as the first connecting member 323, which is steel wire rope or nylon rope, but is not limited to this.

[0050] When the contact head 31 moves from the first end 21 to the second end 22 of the roller brush 20, the contact head 31 can be reset not only by using the reset elastic member 35, but also by the second drive member 324, the second rotating shaft 325 and the second connecting member 326.

[0051] The second rotating shaft 325 is connected to the second driving member 324. The second rotating shaft 325 rotates under the driving action of the second driving member 324. One end of the second connecting member 326 is connected to the second rotating shaft 325, and the other end is connected to the contact head 31. The second connecting member 326 is wound around the second rotating shaft 325 under the action of the second driving member 324, so as to drive the contact head 31 to move from the second end 22 of the roller brush 20 toward the first end 21. The second driving member 324 is preferably a motor, but it is not limited to this.

[0052] In an optional embodiment, the roller brush device 100 further includes two limit switches 40, which correspond to the two ends of the roller brush 20 respectively. When the contact head 31 moves to the first end 21 of the roller brush 20, the contact head 31 contacts one of the two limit switches 40; when the contact head 31 moves to the second end 22 of the roller brush 20, the contact head 31 contacts the other of the two limit switches 40.

[0053] The forming switch 40 corresponding to the second end 22 of the roller brush 20 can move the contact head 31 from the second end 22 of the roller brush 20 to the first end 21. The limit switch 40 corresponding to the first end 21 of the roller brush 20 can stop the drive component 32 from driving the contact head 31 to ensure the separation effect of the hair wrapped around the surface of the roller brush 20.

[0054] This application provides an operating procedure for a cleaning device, including the following steps: The user confirms whether self-cleaning is required. If so, the hair removal procedure is executed in the preset program of the self-cleaning mode of the floor scrubber. For example, in self-cleaning mode, the roller brush is rinsed first, and then the hair removal procedure is executed after rinsing the roller brush to remove hair entangled on the roller brush surface. Specifically, the hair removal procedure can be executed by using a drive component to drive a contact head from the first end of the roller brush along the axis of the roller brush to the second end of the roller brush in a manner that fits against the roller brush surface. The contact head removes the hair it comes into contact with along its movement path. If not, the user toggles the hair removal switch as needed.

[0055] Before executing the hair breaking procedure, the current state of the roller brush is determined. If the roller brush is static, the hair breaking procedure is executed. If the roller brush is in working condition, the roller brush is stopped first, and then the hair breaking procedure is executed.

[0056] When the contact head moves to the second end of the roller brush, triggered by the limit switch, the contact head moves from the second end of the roller brush toward the first end under the action of the reset elastic element or the second driving element. At the same time, the first driving element rotates in the opposite direction.

[0057] When the contact head moves back to the first end of the roller brush, the drive component stops driving under the triggering action of the limit switch corresponding to the first end of the roller brush, and drives the contact head to stop moving.

[0058] It should be understood that the above embodiments are exemplary and are not intended to encompass all possible implementations included in the claims. Various modifications and changes can be made to the above embodiments without departing from the scope of this disclosure. Similarly, the various technical features of the above embodiments can be arbitrarily combined to form other embodiments of this application that may not be explicitly described. Therefore, the above embodiments only illustrate several implementations of this application and do not limit the scope of protection of this patent application.
