Description

Technical Field

[0001] This utility model belongs to the field of cleaning equipment technology, specifically relating to a cleaning module, cleaning equipment and cleaning system. Background Technology

[0002] Floor scrubbers typically have a scraper at the rear of the roller brush. The scraper is in close contact with the surface of the roller brush and can scrape off the wastewater on the roller brush, preventing the wastewater from being carried back to the ground. This allows for efficient wastewater recycling and improves cleaning results.

[0003] Most floor scrubbers on the market currently have fixed wringer blades. A small number have floating wringer blades, but these are passively floating via springs and cannot achieve active control over the water content of the brush. Therefore, it is necessary to improve the existing technology to overcome these shortcomings. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is to provide a cleaning module, cleaning equipment and cleaning system.

[0006] In some embodiments, the rear scraper assembly includes at least a rear scraper that cooperates with the cleaning roller brush, and the drive assembly is configured to adjust the amount of contact of the rear scraper on the cleaning roller brush.

[0007] The front scraper assembly acts on the surface to be cleaned, wherein the front scraper assembly has a scraping state when it is in contact with the surface to be cleaned and a lifting state when it is detached from the surface to be cleaned, and the driving assembly drives the front scraper assembly to switch between the scraping state and the lifting state.

[0008] In some embodiments, during the process of the front scraper assembly switching from the scraping state to the lifting state, the amount of contact between the rear scraper assembly and the cleaning roller brush increases.

[0009] In some embodiments, the drive component has at least a first operating mode and a second operating mode; wherein, in the first operating mode, the drive component drives the front scraper assembly to the raised state, and the drive component acts on the rear scraper assembly to increase the contact amount of the rear scraper assembly;

[0010] In the second operating mode, the driving component drives the front scraper assembly to the scraping state, and the driving component does not act on the rear scraper assembly.

[0011] In some embodiments, the drive component further includes a third operating mode in which the drive component drives the front scraper assembly to the raised state, and the drive component does not act on the rear scraper assembly.

[0012] In some embodiments, the drive assembly has a rotary output end, which is provided with a lever portion that abuts against the rear scraper assembly and a swing arm portion that is connected to the front scraper assembly, and the lever portion and the swing arm portion have a fixed included angle.

[0015] The main body is further provided with a transmission component connected to the first bracket, and the drive component acts on the first bracket through the transmission component.

[0016] In some embodiments, the drive assembly includes a rotary output end, the rotary output end having at least a lever portion, the lever portion having a first state where it rotates in a first direction and acts on the first bracket to push the first bracket forward, and a second state where it rotates in a second direction to remove the force applied to the first bracket.

[0017] In some embodiments, a second guide structure for guiding the movement of the first support is further provided between the body and the first support;

[0018] The second guide structure includes a second chute and a second guide block that cooperates with the second chute.

[0020] The swing arm responds to the rotational motion of the rotary output end, driving the robotic arm to perform linear reciprocating motion in the horizontal direction. A reversing structure is provided between the robotic arm and the front scraper. The reversing structure is configured to switch the horizontal motion of the robotic arm to the lifting motion of the front scraper, so that the front scraper has a scraping state when it is in contact with the surface to be cleaned, and a lifting state when it is at a preset height from the surface to be cleaned in the vertical direction.

[0021] In some embodiments, the reversing structure includes a transmission guide groove disposed on the robotic arm and a protrusion disposed on the front scraper and located within the transmission guide groove;

[0022] The transmission guide groove has a high end and a low end. The protrusion slides from the high end to the low end in response to the movement of the robotic arm toward the right, so that the front scraper comes into contact with the surface to be cleaned.

[0048] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The present utility model will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0049] It should be noted that the terms "first," "second," etc., in the specification, claims, and drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0050] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0051] This utility model provides a cleaning module. In one application scenario, the cleaning module is the floor brush assembly of a floor scrubber, capable of moving across the surface to be cleaned. Of course, the cleaning module includes, but is not limited to, the floor brush assembly of a floor scrubber; it can also be the main body of a window cleaning machine, or other cleaning components with wet mopping functions. The following description uses the floor brush assembly of a floor scrubber as an example, but as can be seen from the above description, the scope of protection of this utility model is not limited thereto.

[0052] In this embodiment of the disclosure, the forward direction of the cleaning module is forward, the backward direction is backward, the horizontal direction perpendicular to the forward and backward direction is left and right, and the direction where gravity is located is up and down.

[0053] like Figures 1 to 4 As shown, the cleaning module includes a body 100, on which a cleaning roller brush 110, a suction port 120, a water distributor, and a clean water tank 130 are provided. The cleaning roller brush 110 is rotatably mounted at the bottom of the body 100 and located in front of the suction port 120. The water distributor is selectively connected to the clean water tank 130 and is used to provide cleaning liquid to the roller brush and / or the surface to be cleaned, so as to wet the cleaning roller brush 110 and / or the surface to be cleaned.

[0054] During the cleaning process, the cleaning roller brush 110 cleans the floor by rolling and rubbing against the surface to be cleaned. The dirt on the floor and the wastewater thrown out by the cleaning roller brush 110 are sucked into the suction port 120 and recycled to the wastewater tank through the suction pipe, thus achieving the goal of "washing-vacuuming-mopping" being completed simultaneously.

[0055] In this embodiment of the present disclosure, the main body 100 is further provided with a front scraper assembly 300 and a rear scraper assembly 200, wherein the front scraper assembly 300 and the rear scraper assembly 200 are respectively located on the front and rear sides of the cleaning roller brush 110. The front scraper assembly 300 and the rear scraper assembly 200 are used to reduce liquid on the cleaning roller brush 110 and / or the surface to be cleaned.

[0056] Furthermore, the main body 100 is also provided with a drive assembly 400 that acts on the rear scraper assembly 200 and the front scraper assembly 300. The drive assembly 400 is used to adjust the position of the front and rear scraper assemblies relative to the cleaning roller brush 110 and / or the surface to be cleaned.

[0057] Regarding the rear scraper assembly 200, such as Figure 2 , Figure 8 and Figure 9 As shown, the rear scraper assembly 200 includes at least a rear scraper 210, which engages with the cleaning roller brush 110. Here, "engagement" refers to abutting engagement. The rear scraper 210 has elastic deformation capability, effectively scraping away wastewater from the cleaning roller brush 110 without excessive compression that would increase the rotational resistance of the cleaning roller brush 110. The rear scraper 210 can be made of silicone, hydrogenated nitrile rubber, or TPE thermoplastic elastomer, etc.

[0058] The drive assembly 400 is used to adjust the amount of contact between the rear scraper 210 and the cleaning roller brush 110. The aforementioned "amount of contact" refers to the amount of indentation on the outer circumferential surface of the cleaning roller brush 110 under the action of the rear scraper 210, which can also be understood as the amount of interference between the rear scraper 210 and the cleaning roller brush 110.

[0059] When the cleaning module performs a cleaning task, the cleaning roller brush 110 rotates, and the drive component 400 drives the rear scraper 210 to actively approach the cleaning roller brush 110. By controlling and adjusting the amount of contact between the rear scraper 210 and the cleaning roller brush 110, water stains on the cleaning roller brush 110 can be efficiently scraped off, the water absorption rate of the cleaning roller brush 110 can be increased, the amount of water stains remaining on the surface to be cleaned can be effectively reduced, and the cleaning effect can be improved.

[0060] When the cleaning module performs the self-cleaning task, the cleaning roller brush 110 rotates to perform the self-cleaning task. After the cleaning roller brush 110 finishes cleaning, the drive component 400 can drive the rear scraper 210 to abut against the cleaning roller brush 110 to squeeze out excess liquid on the cleaning roller brush 110, which is beneficial for drying the cleaning roller brush 110 and improving the drying efficiency.

[0061] The state of the rear scraper 210 when the drive component 400 is not acting is the initial state of the rear scraper 210. In one case, the rear scraper 210 does not contact the cleaning roller brush 110 when not acting on the drive component 400. When the drive component 400 is activated, the rear scraper 210 gradually approaches the cleaning roller brush 110 under the action of the drive component 400. In another case, the rear scraper 210 contacts the outer circumferential surface of the cleaning roller brush 110 when not acting on the drive component 400. At this time, the amount of contact between the rear scraper 210 and the cleaning roller brush 110 is very small. When the drive component 400 is activated, the rear scraper 210 gradually approaches the cleaning roller brush 110 under the action of the drive component 400, and the amount of contact between the rear scraper 210 and the cleaning roller brush 110 gradually increases. Preferably, the rear scraper 210 contacts the outer circumferential surface of the cleaning roller brush 110 in the initial state, at which time the amount of contact is at its minimum.

[0062] The portion of the rear scraper 210 that contacts the cleaning roller brush 110 can be continuously or intermittently distributed in the axial direction. When the rear scraper 210 is intermittently distributed in the axial direction, the portion of the rear scraper 210 that contacts the cleaning roller brush 110 has a comb-like shape, allowing the liquid scraped off the cleaning roller brush 110 to be sucked into the suction port 120 through the gaps between adjacent teeth. At the same time, the comb-like structure helps to scrape off long fibers or hairs wrapped around the cleaning roller brush 110, preventing long fibers or hairs from becoming entangled on the cleaning roller brush 110.

[0063] Specifically, the rear scraper assembly 200 also includes a first bracket 220 that floats on the body 100 in the front-rear direction, and a rear scraper 210 is mounted on the first bracket 220. The rear scraper 210 extends from one axial end of the cleaning roller brush 110 to the other axial end and is detachably mounted on the bottom of the first bracket 220. The rear scraper 210 can be detachably mounted on the bottom of the first bracket 220 by fasteners (screws) or by clips. The first bracket 220 is a water distributor and is located above the suction port 120.

[0064] like Figure 8 and Figure 13 As shown, the first support 220 is floating on the body 100 via a second elastic member 290. One end of the second elastic member 290 is connected to the first support 220, and the other end is connected to the body 100. Multiple second elastic members 290 are provided, and the multiple second elastic members 290 are spaced apart along the axial direction of the cleaning roller brush 110.

[0065] Furthermore, such as Figure 10 and Figure 11 As shown, a mounting and positioning structure is also provided between the rear scraper 210 and the first bracket 220. The mounting and positioning structure includes a protrusion 221 and a positioning hole 211, which cooperate with each other. One of the protrusion 221 and the positioning hole 211 is provided on the rear scraper 210, and the other is provided on the first bracket 220. In one embodiment, the protrusion 221 is provided at the bottom of the first bracket 220, and the positioning hole 211 is provided on the rear scraper 210.

[0066] In this embodiment of the disclosure, the main body 100 is further provided with a transmission assembly connected to the first bracket 220, and the drive assembly 400 acts on the first bracket 220 through the aforementioned transmission assembly. Figure 9 As shown, the transmission assembly includes a limiting seat 230 disposed within the main body 100, a first slider 240 disposed on the limiting seat 230 and sliding along a direction perpendicular to the movement of the first support 220, and a second slider 250 disposed on the limiting seat 230 and connected to the first support 220. The first slider 240 and the second slider 250 abut against each other on their inclined surfaces. In the direction of movement of the first support 220, the second slider 250 is closer to the first support 220 than the first slider 240. When a force is applied to the first slider 240 along a direction perpendicular to the movement of the first support 220 (left or right direction), the first slider 240 is pushed, causing the second slider 250 and the first support 220 to perform linear reciprocating motion in the forward and backward directions.

[0067] like Figure 8As shown, the drive assembly 400 includes a rotary output end, which is provided with at least a lever portion 411. The lever portion 411 has a first state in which it rotates in a first direction and acts on the first bracket 220 through the aforementioned transmission assembly to push the first bracket 220 forward, and a second state in which it rotates in a second direction to remove the force applied to the first bracket 220. The first direction and the second direction are opposite.

[0068] Specifically, the lever portion 411 can abut against the aforementioned transmission assembly, acting on the rear scraper 210 and the first bracket 220 through the transmission assembly. When the lever portion 411 is in the first state, it abuts against the first slider 240 to push the second slider 250 and the first bracket 220 forward. When the lever portion 411 is in the second state, the first bracket 220 is reset under the elastic force of the second elastic member 290.

[0069] A travel limiting structure is also provided between the first slider 240 and the limiting seat 230. The travel limiting structure is used to limit the movement limit position of the first slider 240, thereby limiting the amount of contact between the rear scraper 210 and the cleaning roller brush 110.

[0070] like Figure 9 and Figure 15 As shown, the aforementioned travel limiting structure consists of a first limiting surface 263 and a second limiting surface 264 distributed perpendicular to the movement direction of the first slider 240. The first limiting surface 263 can abut against the second limiting surface 264. One of the first limiting surface 263 and the second limiting surface 264 is provided on the first slider 240, and the other is provided on the limiting seat 230.

[0071] In this embodiment, a first slider 240 and a second slider 250 are disposed within a limiting seat 230, which has a receiving space 231. A portion of the first slider 240 extends to the outside of the receiving space 231 to engage with the drive assembly 400. Furthermore, the drive assembly 400 and the first slider 240 are in abutting engagement. Figure 15 As shown, the portion of the first slider 240 located outside the limiting seat 230 has a first surface 241 that can abut against the lever portion 411 of the drive assembly 400. The portion of the first slider 240 located inside the limiting seat 230 has a second surface 242 that abuts against the second slider 250. The first surface 241 and the movement direction of the first slider 240 form an acute angle, as do the second surface 242 and the movement direction of the first slider 240, and also form an acute angle between the first surface 241 and the second surface 242.

[0072] The second slider 250 is pivotally connected to the first bracket 220 via a pin 280. For example... Figure 11 and Figure 12As shown, a hinge portion 222 protrudes from the side wall of the first bracket 220 near the second slider 250, and a receiving groove 251 for receiving the hinge portion 222 is provided on the second slider 250. A pin 280 passes vertically (up and down) through the second slider 250 and the hinge portion 222.

[0073] Furthermore, a first guide structure 260 is provided between the second slider 250 and the limiting seat 230, the first guide structure 260 being used to guide the movement of the second slider 250. For example... Figure 9 and Figure 14 As shown, the first guide structure 260 includes a first groove 261 and a first guide block 262 that cooperates with the first groove 261. One of the first groove 261 and the first guide block 262 is disposed on the limiting seat 230, and the other is disposed on the second slider 250. The first groove 261 extends along the movement direction of the second slider 250. In one embodiment, the first groove 261 is located on a pair of opposing sidewalls of the second slider 250, and the first guide block 262 is disposed on the limiting seat 230.

[0074] Furthermore, such as Figure 13 As shown, a second guide structure 270 for guiding the movement of the first support 220 is also provided between the first support 220 and the body 100. The second guide structure 270 includes a second slide groove 271 and a second guide block 272 that cooperates with the second slide groove 271. One of the second slide groove 271 and the second guide block 272 is provided on the body 100, and the other is provided on the first support 220.

[0075] In one embodiment, a second groove 271 is disposed within the body 100, and a second guide block 272 is disposed on the first bracket 220. The second guide blocks 272 are distributed at both the left and right ends of the first bracket 220. The second guide blocks 272 can be considered as end structures of the first bracket 220.

[0076] In order to reduce the sliding friction between the second slide groove 271 and the second guide block 272, at least one of the second slide groove 271 and the second guide block 272 is provided with a roller (not shown). The roller can effectively reduce the resistance of the first support 220 in the front and rear directions, making the movement of the first support 220 smoother and avoiding the problem of jamming.

[0077] Regarding the front scraper assembly 300, the front scraper assembly 300 acts on the surface to be cleaned to reduce residual water stains on the surface to be cleaned during the process of pulling the cleaning module backward. The front scraper assembly 300 has a scraping state when in contact with the surface to be cleaned and a raised state when detached from the surface to be cleaned. The drive assembly 400 drives the front scraper assembly 300 to switch between the scraping state and the raised state.

[0078] During the transition from a swiping state to a lifting state, the rear scraper assembly 200 increases its contact area with the cleaning roller brush 110. While the front scraper assembly 300 is transitioning from a swiping state to a lifting state, the cleaning module is in a forward-moving state cleaning the surface to be cleaned. At this time, the increased contact area of ​​the rear scraper assembly 200 with the cleaning roller brush 110 reduces the water content of the cleaning roller brush 110, increases its water absorption rate, and enhances its cleaning and self-cleaning effects.

[0079] like Figure 5 , Figure 6 , Figures 16 to 18 As shown, the front scraper assembly 300 includes a robotic arm 310 connected to the drive assembly 400 and a front scraper 320 slidably connected to the robotic arm 310. The robotic arm 310 performs linear reciprocating motion in the horizontal direction under the action of the drive assembly 400. Specifically, the drive assembly 400 has a rocker arm 412 on its rotary output end. The drive assembly 400 is connected to the robotic arm 310 via the rocker arm 412, and the rocker arm 412 is rotatably connected to the robotic arm 310. The rocker arm 412 drives the robotic arm 310 to perform linear reciprocating motion in the horizontal direction in response to the rotation of the rotary output end. In one embodiment, the drive assembly 400 is a servo motor. Of course, the drive assembly 400 includes, but is not limited to, a servo motor, and can also be other drive sources with a rotary output end, such as a motor, a rotary cylinder, etc.

[0080] A reversing structure is provided between the robotic arm 310 and the front scraper 320. The reversing structure is used to switch the horizontal movement of the robotic arm 310 to the vertical movement of the front scraper 320, so that the front scraper 320 has a scraping state when it is in contact with the surface to be cleaned, and a raised state when it is at a preset height relative to the surface to be cleaned. Here, the "horizontal direction" refers to the axial direction (left and right direction) of the cleaning roller brush 110.

[0081] The reversing structure includes a transmission guide groove 330 on the robotic arm 310 and a protrusion 340 on the front scraper 320 and located within the transmission guide groove 330. The transmission guide groove 330 has a high end and a low end. In one case, the protrusion 340 slides from the high end to the low end in response to the movement of the robotic arm 310 to the right, causing the front scraper 320 to abut against the surface to be cleaned. In another case, the protrusion 340 slides from the low end to the high end and remains at the high end in response to the movement of the robotic arm 310 to the left, keeping the front scraper 320 in a raised state.

[0082] In the embodiments disclosed herein, such as Figure 7As shown, a first elastic element 350 is provided between the robotic arm 310 and the body 100. The first elastic element 350 is used to provide an elastic driving force to switch the front scraper 320 from a scraping state to a lifting state. One end of the first elastic element 350 abuts against the robotic arm 310, and the other end abuts against the body 100.

[0083] Considering that the front scraper 320 is preferably made of a flexible material, in order to ensure that the protrusion 340 can move reliably within the transmission guide groove 330, the front scraper 320 is connected to the robotic arm 310 via a connector 360. The front scraper 320 is located at the bottom of the connector 360, the protrusion 340 is located on the connector 360, and the reversing structure is located between the robotic arm 310 and the connector 360. The connector 360, robotic arm 310, and protrusion 340 are all made of rigid materials. Rigid materials are less prone to deformation, which is more conducive to ensuring the stability and reliability of the movement of the front scraper 320.

[0084] like Figure 4 and Figure 5 As shown, the main body 100 is provided with a roller brush cover 140, and a front scraper assembly 300 is provided on the roller brush cover 140. The front scraper 320 is located on the outside of the roller brush cover 140 and at the bottom of the roller brush cover 140. The roller brush cover 140 is separately arranged in the front-rear direction. The robotic arm 310 is located inside the roller brush cover 140, and the connector 360 is at least partially located inside the roller brush cover 140.

[0085] In summary, in the embodiments of this disclosure, as Figures 16 to 18 As shown, the rotary output end of the drive assembly 400 is provided with a lever portion 411 that abuts against the rear scraper assembly 200 and a swing arm portion 412 that connects to the front scraper assembly 300. The lever portion 411 and the swing arm portion 412 have a fixed included angle. The lever portion 411 and the swing arm portion 412 can also be integrally formed, thus reducing two parts to one and simplifying the installation process.

[0086] In this embodiment of the disclosure, the driving component 400 has at least a first operating mode and a second operating mode. Specifically, as shown in the following embodiments... Figure 16 As shown, in the first working mode, the drive component 400 drives the front scraper assembly 300 to be in a raised state, and the drive component 400 acts on the rear scraper assembly 200 to increase the contact amount of the rear scraper assembly 200. In the first working mode of the drive component 400, the cleaning module is in a forward state, and the cleaning roller brush 110 cleans the surface to be cleaned. At this time, the cleaning roller brush 110 needs to have a good water absorption rate to wipe the water stains on the surface to be cleaned and improve the cleaning effect.

[0087] In the second working mode, such as Figure 17As shown, the drive assembly 400 drives the front scraper assembly 300 into a scraping state, and the drive assembly 400 does not act on the rear scraper assembly 200. In the second working mode, the cleaning module is in a backward pulling state, and the front scraper assembly 300 includes at least a front scraper 320 that cooperates with the surface to be cleaned. During the backward pulling process, the front scraper 320 can reduce water stains on the cleaned surface to a certain extent.

[0088] In this embodiment of the disclosure, the driving component 400 further includes a third operating mode, in which, for example... Figure 18 As shown, the drive assembly 400 drives the front scraper assembly 300 to a raised state. The drive assembly 400 does not act on the rear scraper assembly 200. At this time, the front scraper 320 is not in contact with the surface to be cleaned, and the rear scraper 210 is not in contact with the cleaning roller brush 110, or the rear scraper 210 is in contact with the outer circumferential surface of the cleaning roller brush 110 (the state of minimum contact). Of course, the working modes of the drive assembly 400 include, but are not limited to, the first working mode, the second working mode, and the third working mode, and may also include other working modes, which will not be described in detail here.

[0089] Corresponding to the three working modes of the drive assembly 400, the lever part 411 has a first working position, a second working position and a third working position, wherein the first working position corresponds to the first working mode of the drive assembly 400, the second working position corresponds to the second working mode of the drive assembly 400, and the third working position corresponds to the third working mode of the drive assembly 400.

[0090] Appendix Figure 16 This is a schematic diagram of the lever 411 in its first working position. (See attached diagram) Figure 17 This is a schematic diagram of the lever 411 in the second working position. (See attached diagram) Figure 18 This is a schematic diagram of the lever 411 in the third working position. During the transition of the front scraper assembly 300 from the scraping state to the lifting state, the lever 411 rotates sequentially through the second, third, and first working positions. Specifically, in the first working position, the rear scraper assembly 200 reaches its maximum contact depth with the cleaning roller brush 110; in the second and third working positions, the rear scraper assembly 200 reaches its minimum contact depth with the cleaning roller brush 110.

[0091] In the embodiments disclosed herein, such as Figure 6 As shown, the transmission guide groove 330 includes a first groove 331 inclinedly distributed and a second groove 332 connected to the first groove 331 and horizontally distributed. The first groove 331 has a high end and a low end, and the second groove 332 is connected to the high end of the first groove 331. The high end and low end of the first groove 331 are the high end and low end of the transmission guide groove 330.

[0092] The first groove 331 is located to the left of the second groove 332, and there is an obtuse angle between the first groove 331 and the second groove 332. Of course, the first groove 331 can also be located to the right of the second groove 332. In this embodiment, it is preferred that the first groove 331 is located to the left of the second groove 332. The function of the first groove 331 is to enable the connector 360 and the front scraper 320 to move up and down under the drive of the robotic arm 310. The function of the second groove 332 is to keep the connector 360 and the front scraper 320 in their existing state (in the raised state) when the robotic arm 310 is moving, that is, when the robotic arm 310 moves, the state of the connector 360 and the front scraper 320 remains unchanged.

[0093] The working principle is as follows: The drive assembly 400 drives the lever part 411 and the swing arm part 412 to rotate, thereby causing the first slider 240 to slide left and right and the robotic arm 310 to move left and right. Figure 17 As shown, in the second working mode, the swing arm 412 moves the robotic arm 310 to the far right. Under the action of the transmission guide groove 330, the connector 360 drives the front scraper 320 to move downward. The protrusion 340 is located at the low end of the first groove 331, so that the front scraper 320 contacts the surface to be cleaned, thereby achieving the effect of scraping off water stains. At this time, the lever 411 is located in the second working position, and the lever 411 is in the extreme position far away from the first slider 240.

[0094] like Figure 18 As shown, in the third working mode, the lever part 411 and the swing arm part 412 rotate along the first direction (clockwise direction) by a first preset angle, so that the robotic arm 310 moves to the left by a preset distance. Under the action of the robotic arm 310, the protrusion 340 moves toward the high end of the first groove 331. Preferably, the protrusion 340 moves to the high end of the first groove 331, so that the front scraper 320 and the connecting member 360 are in a raised state. At this time, the lever part 411 is located in the third working position. The lever part 411 is close to the first slider 240 but does not contact the first slider 240, or the lever part 411 just contacts the first slider 240.

[0095] like Figure 16As shown, as the lever 411 and the swing arm 412 continue to rotate in the first direction, the protrusion 340 is located in the second groove 332. The rotation of the lever 411 and the swing arm 412 does not affect the front scraper 320 and the connector 360. The lever 411, however, presses the first slider 240, causing it to slide to the right. Simultaneously, the sliding of the first slider 240 to the right causes the second slider 250 to move the first support 220 forward (closer to the cleaning roller brush 110). The rear scraper 210 reaches its maximum depth on the cleaning roller brush 110, effectively squeezing the cleaning roller brush 110 and reducing its moisture content. It is noteworthy that when the lever 411 is not acting on the first slider 240, the first support 220 floats only under the elastic force provided by the second elastic member 290.
