Description

Floor brush components, cleaning equipment and cleaning systems

[0001] This application claims priority to Chinese Patent Application No. 202520162538.6, filed on January 24, 2025, entitled “Floor brush assembly, cleaning equipment and cleaning system”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of cleaning equipment technology, and more particularly to a floor brush assembly, cleaning equipment, and cleaning system. Background Technology

[0003] Floor scrubbers and other cleaning equipment have become increasingly popular due to their high mopping efficiency and convenience, which greatly reduces the labor intensity and time spent on housework.

[0004] Traditional floor scrubbers typically clean floors using rollers, brush pads, and other cleaning components, followed by water spraying and wastewater collection. However, when stubborn stains are present, traditional floor scrubbers are less effective, sometimes requiring manual cleaning, which is time-consuming, labor-intensive, and reduces cleaning efficiency. Summary of the Invention

[0005] This application provides a floor brush assembly, cleaning equipment, and cleaning system for cleaning stubborn stains, thereby improving cleaning efficiency and effectiveness.

[0006] In a first aspect, this application provides a floor brush assembly, comprising: a housing having a cleaning chamber; a roller brush rotatably disposed in the cleaning chamber for cleaning a surface to be cleaned; a scraper device disposed on the front side of the roller brush, the scraper device being movably connected to the housing, the scraper device being used for scraping and washing the surface to be cleaned; a wiping plate device disposed on the front side of the roller brush, the wiping plate device being movably connected to the housing, the wiping plate device being used for wiping and washing the surface to be cleaned; and a drive device disposed in the housing, the drive device being drively connected to the scraper device and / or the wiping plate device to drive the scraper device and / or the wiping plate device to move.

[0007] The floor brush assembly of this application features a scraper device that effectively cleans hard-to-reach corners and areas like wall corners, while also removing residual watermarks from the floor. This avoids the problem of traditional floor scrubbers being unable to effectively clean these areas. Furthermore, the scrubbing plate device uses hard friction to scrape away stubborn stains adhering to the floor, loosening and detaching them, thus improving the floor scrubber's cleaning ability on heavily soiled surfaces. The drive unit controls the movement of the scraper device and / or the scrubbing plate device, ensuring they are in contact with the surface to be cleaned when needed and can be detached and stored when not in use, maintaining the compactness and functionality of the floor brush assembly. In this way, through the design and control of the scraper device, scrubbing plate device, and drive unit, this floor brush assembly effectively solves the cleaning problems of traditional floor scrubbers in various scenarios, such as dealing with corners, watermarks, and heavy stains. It effectively improves cleaning efficiency and effectiveness, reduces the need for manual intervention, makes cleaning more automated and efficient, and enhances the user experience.

[0008] In one possible implementation, both the scraper device and the wiping plate device have a working position and a suspended position, wherein either the scraper device or the wiping plate device cleans the surface to be cleaned in the working position; and either the scraper device or the wiping plate device is separated from the surface to be cleaned in the suspended position.

[0009] When the squeegee is in the working position, it adheres to the surface to be cleaned, effectively scrubbing the floor. When the scrubbing plate is in the working position, it utilizes the principle of hard friction to generate strong friction with the surface, thereby removing stubborn stains. When the squeegee and scrubbing plate are suspended, they separate from the surface and can be retracted via a drive mechanism, ensuring the compactness of the floor scrubber assembly. Furthermore, this design avoids unnecessary contact between the squeegee and scrubbing plate and the floor during the scrubber's movement, reducing energy consumption and wear, and ensuring the stability and smoothness of the scrubber during operation.

[0010] In one possible implementation, the scraper device and the wiping plate device are configured such that when one is in the working position, the other is in the suspended position; or, both the scraper device and the wiping plate device are in the suspended position; or, both the scraper device and the wiping plate device are in the working position.

[0011] When the squeegee is in the working position, it adheres to the surface to be cleaned, effectively scraping away stubborn stains, especially in hard-to-reach areas like corners and crevices. At this time, the scrubbing plate is suspended in the air to avoid contact with the floor, reducing unnecessary energy consumption and wear. When dealing with stubborn stains, the scrubbing plate can be lowered to the working position to remove the stains through hard friction. This mutually exclusive design of the squeegee and scrubbing plate ensures that the floor scrubber can select the appropriate cleaning tool according to different needs, thereby improving cleaning efficiency and effectiveness. Alternatively, in some cases, such as when the floor scrubber needs to move quickly to cover a large area, or when the floor material is unsuitable for either the squeegee or scrubbing plate, both devices can be adjusted to a suspended position. In this case, the floor scrubber can rely on the roller brush and other cleaning components to complete the cleaning task, while also avoiding unnecessary contact between the squeegee and scrubbing plate and the floor, reducing energy consumption and wear. Alternatively, in some cases, such as when there are stubborn solid materials and liquid stains on the ground, the scraper and scrubbing device can be adjusted to the working position at the same time. The scrubbing device scrapes the solid stains on the ground to loosen them and remove them from the ground, while the scraper can scrape and wash the solid and liquid stains that have been removed from the ground, thereby achieving a thorough cleaning of the ground.

[0012] In one possible implementation, the wiping plate device includes a first working end for cleaning the surface to be cleaned, and the scraper device includes a second working end for cleaning the surface to be cleaned, wherein the end face area of ​​the first working end is larger than the end face area of ​​the second working end.

[0013] The larger contact area of ​​the first working end allows the wiping device to cover large areas more quickly, thus improving cleaning efficiency. The smaller end face area of ​​the second working end is primarily because the scraper mainly removes residual water marks and other debris from the floor. The smaller end face area allows the scraper to make more thorough contact with the floor, ensuring a complete clean. Therefore, the design of the wiping device and the scraper with different end face areas reflects meticulous consideration of different cleaning needs, optimizes the efficiency and effectiveness of cleaning operations, and guarantees a good user experience.

[0014] In one possible implementation, the surface roughness of the first working end is greater than that of the second working end.

[0015] The greater roughness of the first working end means that its surface has more tiny protrusions and depressions. This increases the contact area and friction with the surface to be cleaned during wiping, effectively removing stubborn stains, grease, and other deposits, ensuring cleaning efficiency. The relatively smaller roughness of the second working end makes its surface smoother, helping to reduce frictional resistance with the ground during scraping and avoiding unnecessary damage to the scraper or the ground. In addition, the smooth surface makes it easier to adhere to the ground, ensuring precise and thorough scraping.

[0016] In one possible implementation, the roller brush has a cleaning body, and the hardness of the first working end is greater than the hardness of the cleaning body.

[0017] The first working end has greater hardness, which ensures that the wiping device can more effectively clean stubborn stains through friction when facing them. In addition, by designing a cleaning body with a lower hardness than the first working end, cleaning can be carried out in practice by using the wiping device and the roller brush together to meet different types of cleaning needs.

[0018] In one possible implementation, the scraper device and the wiping plate device are spaced apart in the front-to-back direction.

[0019] This avoids cross-contamination that could result from the scraper and wiping plate devices being closely adjacent or overlapping, such as the scraped stains and residues being reapplied to the floor by the wiping plate device, thus ensuring the hygiene and quality of the cleaning process.

[0020] In one possible implementation, the wiping plate device is located between the scraper device and the roller brush.

[0021] The above design allows the roller brush, in conjunction with water flow and suction, to perform a final cleaning of the floor after the scraper or scrubbing device has finished cleaning, removing even the smallest stains and ensuring a clean floor. Therefore, placing the scrubbing device between the scraper and the roller brush optimizes the cleaning process, improves cleaning efficiency and quality, and enhances the adaptability and flexibility of the floor scrubber.

[0022] In one possible implementation, the wiping device also has a self-cleaning position, in which the wiping device contacts the roller brush and performs self-cleaning through the roller brush.

[0023] The cleanliness of the wiping device directly affects the cleaning quality of the floor scrubber. The self-cleaning mechanism ensures the cleanliness of the wiping device, guaranteeing the stability and efficiency of the floor scrubber during cleaning operations. In addition, the design of the self-cleaning position allows the floor scrubber to clean the wiping device without interrupting the cleaning operation, improving cleaning efficiency, reducing manual intervention, and lowering the difficulty of operation.

[0024] In one possible implementation, at least a portion of the structure of the wiping device is rotatable relative to the housing, allowing the wiping device to rotate between the suspended position and the self-cleaning position.

[0025] By automatically or manually rotating the scrubbing plate to the self-cleaning position, the floor scrubber can clean the scrubbing plate without interrupting the cleaning operation, improving cleaning efficiency. Furthermore, the self-cleaning design of the scrubbing plate reduces the difficulty of operation, maintaining the scrubbing machine's cleaning performance and stability without the need for frequent replacement or cleaning of the scrubbing plate. Clearly, the rotatable design of the scrubbing plate allows it to move flexibly between the suspended position and the self-cleaning position, enhancing the floor scrubber's flexibility and functionality, thereby improving cleaning efficiency and user experience.

[0026] In one possible implementation, the floor brush assembly further includes a foam nozzle for spraying a stain dissolving agent onto the surface to be cleaned.

[0027] By pre-spraying stain dissolving agent, the machine can help remove stubborn stains on the floor, such as oil stains and grease, thereby improving cleaning efficiency. Furthermore, the foam nozzle design makes the cleaning process more intuitive and efficient; users can see the stains being broken down and removed simply by operating the machine, enhancing the user experience.

[0028] In one possible implementation, the foam nozzle is located on the housing or the wiping plate device.

[0029] By placing foam nozzles on the scrubbing plate device, the stain dissolving agent can be sprayed onto the area where the device contacts the floor. This allows the agent to directly and effectively target stubborn stains, accelerating their breakdown. Furthermore, while the scrubbing plate device itself has stain-removing capabilities, the foam nozzle design further enhances cleaning power. The dissolving agent penetrates even the smallest crevices in the stains, combining with the physical friction of the scrubbing plate device to create a dual cleaning effect, ensuring high cleaning efficiency.

[0030] In one possible implementation, the driving device includes: a driving member having a rotatable output swing arm; a transmission member hinged to the output swing arm, the transmission member being adapted to slide along the width direction of the housing under the drive of the output swing arm; either the wiping plate device or the scraper device is adapted to convert the sliding of the transmission member along the width direction of the housing into a vertical lifting motion.

[0031] By rotating the drive component and sliding the transmission component, the scrubbing plate or scraper device can be adjusted to a preset position to clean the floor. It is evident that the rotation of the drive component, the sliding of the transmission component, and the lifting and lowering design of the scrubbing plate or scraper device improve the cleaning efficiency and flexibility of the floor scrubber.

[0032] In one possible implementation, the transmission member has a first guide post on the side facing the wiping device; the wiping device has a first movable groove extending through the front and rear direction of the housing, the first movable groove including a first horizontal section extending along the width direction of the housing and a first inclined section inclined relative to the first horizontal section; the first guide post is inserted into the first movable groove, wherein when the first guide post is in the first horizontal section, the wiping device is in a suspended position, and when the first guide post is in the first inclined section, the wiping device performs a lifting and lowering movement.

[0033] The combined use of the first guide column and the first movable groove ensures stable and smooth lifting and lowering movement of the scrubbing device, reducing shaking and noise. Furthermore, since the first movable groove includes a first horizontal section and a first inclined section, the lifting and lowering speed of the scrubbing device can be adjusted by designing the inclination angle and length of the first inclined section. Therefore, by introducing the first guide column and the first movable groove, the transmission mechanism of the floor scrubber and the lifting and lowering movement of the scrubbing device are optimized, improving the stability and flexibility of the floor scrubber and ensuring its cleaning efficiency.

[0034] In one possible implementation, the wiping device includes: a first movable plate, with a first movable groove formed on the first movable plate; and a wiping component, detachably disposed at the bottom end of the first movable plate, the wiping component being used to perform wiping operations on the surface to be cleaned.

[0035] The combination of the first movable plate and the first guide column improves the flexibility and convenience of using and storing the scrubbing plate. Furthermore, the scrubbing plate is easy to install and remove, and can be replaced when damaged or severely worn. Thus, by introducing the first movable plate and the detachable scrubbing plate design, the floor scrubber's flexibility and ease of use are enhanced, while its cleaning performance and maintainability are also optimized.

[0036] In one possible implementation, the transmission member has a second guide post on the side facing the scraper device; the scraper device has a second movable groove extending through the front-rear direction of the housing, the second movable groove including a second horizontal segment extending along the width direction of the housing and a second inclined segment inclined relative to the second horizontal segment; wherein the intersection of the second horizontal segment and the second inclined segment and the projection of the intersection of the first horizontal segment and the first inclined segment in the reference plane are opposite to each other in the front-rear direction, and the reference plane is parallel to the surface to be cleaned.

[0037] The combined use of the second guide column and the second movable groove ensures stable and smooth lifting and lowering movement of the scraper device, reducing shaking and noise. Furthermore, since the second movable groove includes a second horizontal section and a second inclined section, the lifting and lowering speed of the scraper device can be adjusted by designing the inclination angle and length of the second inclined section. The wiping plate device and the scraper device are connected to the transmission component via the first and second guide columns, respectively, and achieve lifting and lowering movements via the first and second movable grooves, respectively. This design allows for independent control of both, improving the flexibility and cleaning efficiency of the floor scrubber. It also enables the floor scrubber to adapt to different floor surfaces and cleaning needs, allowing the lifting and lowering of either the wiping plate device or the scraper device to be operated according to actual requirements.

[0038] In one possible implementation, the second inclined segment is opposite to the first horizontal segment along the front-rear direction of the housing, and the lengths of the projections of the second inclined segment and the first horizontal segment in the reference plane are equal; the second horizontal segment is opposite to the first inclined segment along the front-rear direction of the housing, and the lengths of the projections of the second horizontal segment and the first inclined segment in the reference plane are equal.

[0039] This improves the stability and coordination of the wiping plate device and the scraper device during the lifting process, helps to ensure the continuity and uniformity of the position switching of the wiping plate device and the scraper device, and ensures the compactness and cleaning efficiency of the floor scrubber.

[0040] Secondly, this application also provides a cleaning device, including the floor brush component in any of the above possible implementations.

[0041] Thirdly, this application also provides a cleaning system, including a cleaning base station and a cleaning device as described in the above possible implementations, wherein the cleaning base station is at least configured to clean the floor brush assembly of the cleaning device.

[0042] The floor brush assembly, cleaning equipment, and cleaning system provided in this application allow the roller brush to rotate and remove most stains and dust by contacting the floor when floor cleaning is required. When the floor scrubber moves to hard-to-reach corners such as wall corners, or when there are still a few water marks on the floor, the drive unit can drive the squeegee device to work. The squeegee device makes contact with the floor and scrubs the floor with the movement of the floor brush assembly. When encountering stubborn stains that are difficult to remove by the roller brush and squeegee device, the drive unit drives the scrubbing plate device to contact the floor and, through hard friction, generates strong friction with the floor, causing the stubborn stains to loosen and detach from the floor. Then, with the cooperation of the roller brush or squeegee, a thorough cleaning is performed. When the squeegee device and scrubbing plate device are not needed, the drive unit can store them to reduce unnecessary wear and tear on the floor or the squeegee / scrubbing plate.

[0043] This application incorporates a scrubbing plate device on the floor scrubber, effectively solving the problems that traditional floor scrubbers may face when dealing with stubborn stains, such as requiring multiple round trips or even manual cleaning. By utilizing the hard friction of the scrubbing plate, the stains no longer adhere to the floor. With the cooperation of the roller brush or squeegee, the floor is thoroughly cleaned. This device can handle various types of dirt and grime, ensuring cleaning efficiency and effectiveness, reducing the need for manual intervention, making cleaning work more automated and efficient, and improving the user experience.

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to specific embodiments. Detailed Implementation

[0063] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0064] Floor scrubbers and other cleaning equipment have become increasingly popular due to their high mopping efficiency and convenience, significantly reducing the labor intensity and time spent on housework. Traditional floor scrubbers typically include a clean water tank, a wastewater tank, a roller brush, a power supply, a drive unit, and a negative pressure assembly. During operation, the power supply drives the roller brush via the drive unit. Simultaneously, the clean water tank sprays water onto the roller brush or the floor. Dirt and debris are then drawn into the wastewater tank by the suction of the negative pressure assembly, thus cleaning the floor.

[0065] In short, floor scrubbers typically clean floors using rollers, brushes, and other cleaning components, followed by water spraying and wastewater collection. However, when stubborn stains are present, traditional floor scrubbers often fail to achieve good cleaning results, sometimes requiring manual cleaning, which is time-consuming, labor-intensive, and reduces cleaning efficiency.

[0066] In view of this, this application provides a floor brush assembly, a cleaning device 1, and a cleaning system 3. When floor cleaning is required, the roller brush starts to rotate, removing most stains and dust by contacting the floor. When the floor scrubber moves to a corner or a hard-to-clean corner, the drive unit drives the scraper device to work, which contacts the floor and scrapes away stains and residues in the corner as the floor brush assembly moves. When encountering stubborn stains, the drive unit drives the scrubbing plate device to work, which contacts the floor and generates strong friction through hard friction, removing stubborn stains as the floor brush assembly moves. When the scraper device and scrubbing plate device are not needed, the drive unit can store them. When needed, the drive unit releases them to a preset position to start working. In this way, the floor brush assembly, through the design and control of the scraper device, wiping plate device and drive device, effectively solves the problems that traditional floor scrubbers may face when dealing with stubborn stains, such as needing to make multiple rounds to achieve cleaning, or even needing manual cleaning. It ensures cleaning efficiency and effect, reduces the need for manual intervention, makes cleaning work more automated and efficient, and improves the user experience.

[0067] The floor brush assembly 10 according to an embodiment of the first aspect of this application is described below with reference to Figures 1-16.

[0068] Referring to Figures 1-7, the floor brush assembly 10 of this embodiment can be adapted to cleaning equipment 1 such as floor scrubbers and sweepers. The floor brush assembly 10 includes a housing 100, a roller brush 200, a scraper device 300, a wiping plate device, and a drive device 500.

[0069] The housing 100 includes a cleaning chamber 110, which can be a closed or semi-closed cleaning environment to protect internal components from external damage and to centrally collect cleaning wastewater. Optionally, the housing 100 can be made of high-strength, corrosion-resistant materials such as stainless steel, aluminum alloy, or special plastics to ensure its durability and stability.

[0070] The roller brush 200, as a basic cleaning tool, removes most stains by rotating and contacting the floor. Specifically, the roller brush 200 is rotatably mounted in the cleaning chamber 110 to clean the surface to be cleaned. Optionally, the roller brush 200 can be made of wear-resistant and durable materials such as nylon, polyester fiber, or special synthetic materials to ensure cleaning effectiveness and durability. Specifically, the diameter, rotation speed, and bristle density of the roller brush 200 can be selectively designed according to the power of the floor scrubber and the usage scenario, and are not limited here.

[0071] A scraper device 300 is located on the front side of the roller brush 200 and is movably connected to the housing 100. The scraper device 300 is used to scrape and wash the surface to be cleaned. Specifically, the scraper device 300 scrapes and washes the floor along with the movement of the floor brush assembly 10. Optionally, for hard-to-clean corner stains such as wall corners, the scraper device 300 can quickly remove stains, thus overcoming the shortcomings of traditional floor brush assemblies 10 in cleaning corner stains.

[0072] Optionally, the scraper device 300 may include a scraper frame 320 and scraping conditions 330 mounted on the scraper frame 320. The scraping conditions 330 may be made of wear-resistant and scratch-resistant materials such as rubber, silicone, or special synthetic materials to ensure cleaning effectiveness and durability. Specifically, the shape, angle, and hardness of the scraping conditions 330 can be selectively designed according to the usage scenario and the floor material, and are not limited here.

[0073] A scrubbing device 400 is located in front of the roller brush 200 and is movably connected to the housing 100. The scrubbing device 400 is used to scrub the surface to be cleaned. Specifically, the scrubbing device 400 can further remove stubborn stains through hard scrubbing. Optionally, when it is necessary to clean a floor with stubborn stains, the scrubbing device 400 applies strong friction to the floor to remove the stubborn stains.

[0074] Optionally, the wiping plate device 400 can be made of hard materials such as rubber, plastic, or special synthetic materials to ensure cleaning effectiveness and durability. Optionally, the surface of the wiping plate 430 can have a certain degree of roughness to increase friction with the ground. Specifically, the shape, size, and hardness of the wiping plate 430 should be selectively designed according to the usage scenario of the floor scrubber and the ground material, and are not limited here.

[0075] Optionally, the wiping device 400 may also have adjustable wiping intensity and wiping frequency to adapt to different cleaning needs. Optionally, the wiping device 400 may also be designed with protection mechanisms, such as limit switches and pressure sensors, to control the wiping intensity and wiping frequency and prevent the wiping device 400 from causing excessive wear or damage to the floor.

[0076] Both the scraper device 300 and the wiping device 400 are located on the front side of the roller brush 200. In one example, the scraper device 300 may be located on the front side of the wiping device 400; in another example, the wiping device 400 may be located on the front side of the scraper device 300.

[0077] A drive device 500 is disposed in the housing 100. The drive device 500 is driveably connected to the scraper device 300 and the wiping plate device 400 to drive the scraper device 300 and the wiping plate device 400 to move; or the drive device 500 is driveably connected to the scraper device 300 to drive the scraper device 300 to move; or the drive device 500 is driveably connected to the wiping plate device 400 to drive the wiping plate device 400 to move. Specifically, the drive device 500 can provide power to the scraper device 300 and / or the wiping plate device 400 to ensure that either or both can move in a preset manner. For example, the drive device 500 can drive the scraper device 300 and / or the wiping plate device 400 to achieve reciprocating motion in space, and can also drive the scraper device 300 and / or the wiping plate device 400 to achieve storage and release actions.

[0078] It should be noted that the movement of the drive device 500 to drive the scraper device 300 or the wiping device 400 can be varied. As long as the drive device 500 enables the scraper device 300 or the wiping device 400 to move in a preset manner, it is within the protection scope of this application and is not limited here.

[0079] Optionally, the drive unit 500 may include an electric motor, a hydraulic motor, or a pneumatic motor. Optionally, the drive unit 500 may also be connected to a control system to achieve precise control, including starting, stopping, and speed adjustment, to ensure that the movement of the scraper device 300 and the wiping plate device 400 meets the cleaning requirements.

[0080] As can be seen, when the floor brush assembly 10 provided in this application needs to clean the floor, the roller brush 200 starts to rotate, removing most of the stains and dust by contacting the floor; when the floor scrubber moves to a corner or a hard-to-clean corner, the drive unit 500 drives the scraper device 300 to work, the scraper device 300 makes contact with the floor, and scrapes away stains and residues in the corner as the floor brush assembly 10 moves; when encountering stubborn stains, the drive unit 500 drives the scrubbing device 400 to work, the scrubbing device 400 contacts the floor and generates strong friction with the floor through hard friction, removing stubborn stains as the floor brush assembly 10 moves; when the scraper device 300 and scrubbing device 400 are not needed, the drive unit 500 can store them, and when they are needed, the drive unit 500 releases them to the preset position to start working.

[0081] The scraper device 300 effectively cleans hard-to-reach corners such as wall corners, avoiding the problem of traditional floor scrubbers being unable to effectively clean these areas. Furthermore, the wiping device 400 removes stubborn stains through hard friction, avoiding the need for multiple passes required by traditional floor scrubbers, thus improving cleaning efficiency and effectiveness. The drive device 500 drives the scraper device 300 and the wiping device 400, ensuring they work when needed and are stored away when not, maintaining the compactness and functionality of the floor brush assembly 10. In this way, through the design and control of the scraper device 300, the wiping device 400, and the drive device 500, the floor brush assembly 10 effectively solves the problems that traditional floor scrubbers may face when dealing with stubborn stains, such as requiring multiple passes or even manual cleaning. This improves the cleaning effect of stubborn stains by more than 50%, ensuring cleaning efficiency and effectiveness, reducing the need for manual intervention, making cleaning more automated and efficient, and enhancing the user experience.

[0082] In some embodiments, the floor brush assembly 10 may also include pressure sensors, displacement sensors, etc., to detect the working status of the scraper device 300 and the wiping plate device 400, and ensure cleaning effect.

[0083] In some embodiments, referring to Figures 8 to 13, both the scraper device 300 and the wiping device 400 have a working position 610 and a suspended position 620. Either the scraper device 300 or the wiping device 400 cleans the surface to be cleaned in the working position 610; either the scraper device 300 or the wiping device 400 is separated from the surface to be cleaned in the suspended position 620.

[0084] Specifically, when the scraper device 300 is in the working position 610, the scraper device 300 will adhere to the surface to be cleaned. When the scraper device 300 moves to the corners and hard-to-clean corners, it can remove stains and residues in these areas. When the wiping device 400 is in the working position 610, it can use the principle of hard friction to generate strong friction with the surface to be cleaned, thereby removing stubborn stains.

[0085] When the squeegee device 300 and the wiping plate device 400 are in the suspended position 620, they will be separated from the surface to be cleaned and can be stored by the drive device 500, ensuring the compactness of the floor brush assembly 10. In addition, it avoids unnecessary contact between the squeegee device 300 and the wiping plate device 400 and the ground during the movement of the floor scrubber, reducing the energy consumption and wear of the floor scrubber and ensuring the stability and smoothness of the floor scrubber during movement.

[0086] Optionally, both the scraper device 300 and the wiping plate device 400 have a working position 610 and a suspended position 620, which can be achieved by the drive device 500. For example, the drive control of the drive device 500 can be automatic or manual. Specifically, automatic control can rely on sensors and algorithms to intelligently adjust the positions of the scraper device 300 and the wiping plate device 400 according to the movement trajectory and cleaning needs of the floor scrubber. Manual control allows the user to operate the machine via a control panel or remote control according to the actual working conditions.

[0087] In some embodiments, in conjunction with Figures 10 to 13, the scraper device 300 and the wiping plate device 400 are configured such that when one is in the working position 610, the other is in the suspended position 620.

[0088] That is, when the scraper device 300 is in the working position 610, it will adhere to the surface to be cleaned, especially for hard-to-clean areas such as corners and crevices. At this time, the wiping device 400 is adjusted to the suspended position 620 to avoid contact with the ground, thereby reducing unnecessary energy consumption and wear. Conversely, when stubborn stains need to be treated, the wiping device 400 can be lowered to the working position 610 to remove stains through hard friction, while the scraper device 300 rises to the suspended position 620.

[0089] Thus, the design of the scraper device 300 and the wiping device 400 ensures that the floor scrubber can select the appropriate cleaning tools according to different needs during the cleaning process, thereby improving cleaning efficiency and effect. It avoids the situation where both devices are in contact with the surface to be cleaned, forming multiple points of support with the surface to be cleaned, which is not conducive to the wiping device 400 or the scraper device 300 applying sufficient downward pressure to the surface to be cleaned to achieve effective cleaning.

[0090] In some embodiments, referring to Figures 8 and 9, both the scraper device 300 and the wiping plate device 400 are in a suspended position 620.

[0091] Understandably, in some situations, such as when the floor scrubber needs to move quickly to cover a large area, or when the floor material is not suitable for using the squeegee 300 or the scrubbing plate 400, both the squeegee 300 and the scrubbing plate 400 can be adjusted to the suspended position 620. In this way, the floor scrubber can rely on the roller brush 200 and other cleaning components to complete the cleaning task, while also avoiding unnecessary contact between the squeegee 330 and the scrubbing plate 430 and the floor, reducing energy consumption and wear.

[0092] In some embodiments, in conjunction with Figures 1 to 5, as well as Figures 8, 10 and 12, the drive device 500 is connected to the scraper device 300 and the wiping plate device 400 respectively, so as to drive the scraper device 300 and the wiping plate device 400 to perform lifting and lowering movements respectively.

[0093] The drive unit 500 is one of the core components of the floor scrubber. It connects to the squeegee device 300 and the scrubbing plate device 400, and controls the lifting and lowering movements of the squeegee device 300 and the scrubbing plate device 400. This connection and control method ensures that the floor scrubber can adjust the position of the squeegee and scrubbing plate 430 according to usage requirements during the cleaning process.

[0094] Optionally, the drive unit 500 may include a transmission mechanism, such as a motor, gears, connecting frame, etc., to provide the power required for lifting the scraper device 300 and the wiping plate device 400. This lifting movement allows the scraper device 300 and the wiping plate device 400 to be in contact with or completely separated from the ground as needed, thereby achieving different cleaning needs.

[0095] Thus, by precisely controlling the raising and lowering of the scraper device 300 and the scrubbing plate device 400, the drive unit 500 enables the floor scrubber to efficiently remove stains and residues. For example, when stubborn stains need to be treated, the scrubbing plate device 400 can be lowered to the working position 610 to remove stains through hard friction; when areas that are difficult to clean, such as corners, need to be treated, the scraper device 300 can be lowered to the working position 610 to scrape away corner stains; and when rapid movement is needed to cover a large area, the scraper and scrubbing plate device 430 can be raised simultaneously to the suspended position 620 to reduce energy consumption and wear.

[0096] Optionally, to achieve precise lifting and lowering of the squeegee device 300 and the scrubbing device 400, the floor brush assembly 10 may also include a control system. The control system can be connected to the drive unit 500 and, based on factors such as the floor scrubber's movement trajectory, cleaning needs, and floor material, controls the drive unit 500 to adjust the positions of the squeegee device 300 and the scrubbing device 400. Furthermore, a manual control option can be provided, allowing users to adjust or operate the system according to actual conditions.

[0097] Optionally, to achieve precise control, the floor brush assembly 10 can also be equipped with sensors, such as pressure sensors and displacement sensors, to monitor the working status of the scraper device 300 and the wiping device 400 in real time, or to monitor the dirt level of the floor, and feed the data back to the control system. The control system can then adjust the position, lifting speed, etc. of the scraper device 300 and the wiping device 400 through the drive device 500, etc., to achieve the cleaning operation.

[0098] In some embodiments, referring to FIG3, the wiping plate device 400 includes a first working end 400a for cleaning the surface to be cleaned, and the scraper device 300 includes a second working end 300a for cleaning the surface to be cleaned, wherein the end face area of ​​the first working end 400a is greater than the end face area of ​​the second working end 300a.

[0099] Understandably, the wiping plate device 400 can achieve hard wiping removal of stubborn stains, while the scraper device 300 can achieve convenient cleaning of stains in corners and other hard-to-reach areas.

[0100] Therefore, the first working end 400a, as the main working part of the wiping device 400, can be designed with a large contact area to effectively cover and remove stubborn stains. Its material and design can emphasize hardness and wear resistance to ensure sufficient friction during wiping while avoiding excessive wear on the floor. To achieve flexible scraping, such as in hard-to-reach corners and crevices, the second working end 300a of the scraper device 300 can be designed with a relatively small end face area, possessing a preset shape and material to ensure it conforms to the floor, thereby effectively removing stains and residues.

[0101] Thus, the larger contact area of ​​the first working end 400a allows the wiping device 400 to cover a large area more quickly, thereby improving cleaning efficiency, while the smaller end face area of ​​the second working end 300a allows it to handle details more precisely, ensuring thorough cleaning.

[0102] As can be seen, the design of the wiping plate device 400 and the scraper device 300 with different end face areas reflects careful consideration of different cleaning needs, optimizes the efficiency and effectiveness of cleaning operations, and ensures the user experience.

[0103] In some embodiments, the surface roughness of the first working end 400a is greater than that of the second working end 300a. For example, the first working end 400a of the wiping device 400 may be made of a material with higher hardness and wear resistance, and its surface roughness may be increased by processes such as sandblasting and grinding; while the second working end 300a of the scraper device 300 may be made of a soft, smooth material, and its surface roughness may be reduced by processes such as polishing.

[0104] The larger end-face roughness of the first working end 400a means that the surface of the first working end 400a has more tiny protrusions and depressions. This ensures that the contact area and friction with the surface to be cleaned can be increased during the wiping process, thereby effectively removing stubborn stains, grease and other attachments and ensuring cleaning efficiency.

[0105] The relatively small end face roughness of the second working end 300a makes the surface of the second working end 300a smoother, which helps to reduce the frictional resistance with the ground during the scraping process and avoid unnecessary damage to the ground. In addition, the smooth surface is also easier to adhere to the ground, ensuring the accuracy and thoroughness of the scraping.

[0106] Furthermore, in practical applications, the difference in surface roughness between the first working end 400a and the second working end 300a allows them to handle different types of stains and floor materials respectively. For example, when it is necessary to remove stubborn stains or grease, the scrubbing device 400 with a larger roughness can be selected, while when it is necessary to protect the floor or treat fine stains, it can be switched to the scraper device 300 with a smaller roughness.

[0107] In some embodiments, referring to Figures 9, 11, and 13, the roller brush 200 has a cleaning body, and the hardness of the first working end 400a is greater than the hardness of the cleaning body. Optionally, the cleaning body can be bristles, a brush blade, etc., and for example, the brush blade can be made of soft plastic.

[0108] The first working end 400a has high rigidity, which is beneficial for improving the cleaning effect on stubborn stains; the cleaning body can have appropriate rigidity so that it can remove stains during the cleaning process without causing excessive wear to the floor. For example, the material and design of the cleaning body can be designed and selected according to different floor materials and stain types, and are not limited here.

[0109] Thus, by designing a cleaning body with a hardness less than that of the first working end 400a, the cleaning of the wiping plate device 400, the roller brush 200 and other cleaning components can be ensured in practical applications, ensuring the coordinated work of multiple mechanisms and meeting different types of cleaning needs.

[0110] In some embodiments, referring to Figures 9, 11, and 13, the scraper device 300 and the wiping plate device 400 are spaced apart in the front-to-back direction. Optionally, in some examples, the scraper device 300 may be designed on the front side of the wiping plate device 400, and in other examples, the scraper device 300 may be designed on the rear side of the wiping plate device 400.

[0111] In this way, cross-contamination that may occur if the scraper device 300 and the wiping device 400 are closely adjacent or overlapping is avoided, such as the scraped stains and residues being reapplied to the ground by the wiping device 400, thus ensuring the cleaning effect.

[0112] Understandably, when designing a floor scrubber, the distance between the scraper device 300 and the scrubbing device 400 can be adjusted according to actual needs. An appropriate distance can ensure the efficiency and thoroughness of the cleaning operation.

[0113] In some embodiments, in conjunction with Figures 9, 11 and 13, the wiping plate device 400 is located between the scraper device 300 and the roller brush 200.

[0114] Thus, it is understandable that, in one example, the scraper device 300 is designed at the front, the wiping plate device is designed in the middle, and the roller brush 200 is designed at the rear. This front-position design of the scraper device 300 allows it to directly contact and scrape away dirt from the base of the wall when the floor brush assembly 10 cleans hard-to-reach areas such as corners, ensuring convenient cleaning.

[0115] The rear position design of the roller brush 200 allows it to perform a final cleaning of the floor after the scraper device 300 or the wiping plate device 400 has finished cleaning, using water flow and suction to remove tiny stains and ensure the floor remains clean.

[0116] It is evident that placing the wiping device 400 between the scraper device 300 and the roller brush 200 optimizes the cleaning process, improves cleaning efficiency and quality, and enhances the adaptability and flexibility of the floor scrubber.

[0117] In some embodiments, the wiping device 400 also has a self-cleaning position, in which the wiping device 400 contacts the roller brush 200 and performs self-cleaning by the roller brush 200.

[0118] Specifically, when the floor scrubber is in the self-cleaning position, the scrubbing plate device 400 will be adjusted to contact the roller brush 200. The rotation of the roller brush 200 will generate friction with the scrubbing plate device 400, thereby removing the stains and particles attached to the scrubbing plate device 400.

[0119] The cleanliness of the wiping device 400 directly affects the cleaning quality of the floor scrubber. The self-cleaning mechanism ensures the cleanliness of the wiping device 400, guaranteeing the stability and efficiency of the floor scrubber during cleaning operations. Furthermore, the design of the self-cleaning position allows the floor scrubber to clean the wiping device 400 without interrupting the cleaning operation, improving cleaning efficiency, reducing manual intervention, and lowering the difficulty of operation.

[0120] Optionally, the floor brush assembly 10 may also be designed with a safety locking mechanism to ensure the safety and stability of the floor brush assembly 10 during the self-cleaning process.

[0121] In some embodiments, at least a portion of the structure of the wiping device 400 is rotatable relative to the housing 100, so that the wiping device 400 rotates between a suspended position 620 and a self-cleaning position.

[0122] Optionally, this rotatable design can be achieved through hinges, bearings or other rotating mechanisms to ensure smooth rotation of the wiping plate device 400.

[0123] When the wiping device 400 is in the storage state, it can be in a suspended position 620, maintaining a certain distance from the ground. When it is necessary to clean the wiping device 400, the wiping device 400 can be automatically or manually rotated to the position of contact with the roller brush 200, that is, the self-cleaning position. The friction between the wiping device 400 and the roller brush 200 can remove stains and residues on the wiping device 400.

[0124] By automatically or manually rotating the wiping device 400 to the self-cleaning position, the floor scrubber can clean the wiping device 400 without interrupting the cleaning operation, thus improving cleaning efficiency. In addition, the self-cleaning design of the wiping device 400 reduces the difficulty of operating the floor scrubber, and the cleaning performance and stability of the floor scrubber can be maintained without frequent replacement or cleaning of the wiping device 400.

[0125] As can be seen, the rotatable design of the wiping plate device 400 allows it to rotate flexibly between the suspended device and the self-cleaning position, enhancing the flexibility and functionality of the floor scrubber, thereby improving cleaning efficiency and user experience.

[0126] In some embodiments, referring to FIG14, the floor brush assembly 10 may further include a foam nozzle 700 for spraying a stain dissolving agent onto the surface to be cleaned. The foam nozzle 700 is capable of spraying a stain dissolving agent onto the surface to be cleaned, and the stain dissolving agent can penetrate into the tiny crevices of the stain, break down the stain, and make the stain easier to remove by cleaning tools, such as the scrubbing plate device 400, the roller brush 200, etc.

[0127] By pre-spraying a stain dissolving agent, the machine can help remove stubborn stains on the floor, such as oil and grease, thereby improving cleaning efficiency. Furthermore, the design of the 700 foam nozzle makes the cleaning process more intuitive and efficient; users can see the stains being broken down and removed simply by operating the machine, enhancing the user experience.

[0128] Optionally, the position of the foam nozzle 700 may need to be designed according to the overall structure of the floor scrubber and the cleaning needs, so that the stain dissolving agent can be sprayed onto the surface to be cleaned and avoids interference with other components.

[0129] Optionally, the spray angle and range of the foam nozzle 700 can be designed according to cleaning needs and floor material. For example, for flat and uniform floors, a larger spray range and angle can be selected; for uneven or complex floors, the spray angle and range can be adjusted to adapt to the floor shape.

[0130] In some embodiments, the foam nozzle 700 may be disposed on the housing 100 or the wiping plate device 400.

[0131] In one example, the foam nozzle 700 can be designed between the scraper device 300 and the wiping plate device 400. When the wiping plate device 400 is lowered to the working position 610, the scraper device 300 is raised to the suspended position 620, and correspondingly, the foam nozzle 700 is exposed and can spray stain dissolving agent. In another example, the foam nozzle 700 can be positioned directly below the wiping plate device 400 or on the working surface of the wiping plate device 400, and stain dissolving agent can be sprayed as needed.

[0132] By placing the foam nozzle 700 on the wiping device 400, the stain dissolving agent can be sprayed onto the area where the wiping device 400 contacts the ground. In this way, the stain dissolving agent can directly and effectively act on the stains, accelerating their decomposition. Furthermore, the wiping device 400 itself has stain removal capabilities, and the design of the foam nozzle 700 further enhances its cleaning ability. The stain dissolving agent can penetrate into the tiny crevices of the stains, combining with the physical friction of the wiping device 400 to create a dual cleaning effect, ensuring cleaning efficiency.

[0133] In addition, placing the foam nozzle 700 on the wiping plate device 400 ensures that the solvent is sprayed only onto the area that needs to be cleaned, thereby reducing unnecessary waste and helping to lower cleaning costs.

[0134] Optionally, the spray pressure and flow rate of the foam nozzle 700 can be adjusted according to the type of stain and the floor material. It should be noted that excessive spray pressure may cause solvent splattering, while insufficient spray pressure may prevent the solvent from being effectively sprayed onto the stain.

[0135] In some embodiments, the foam nozzle 700 is configured to spray a stain dissolving agent with a preset shape toward the surface to be cleaned, the length of which is similar to or the same as the length of at least one of the roller brush 200 and the scrubbing device 400.

[0136] This design allows the solvent to more precisely cover the area to be cleaned by the roller brush 200 or the scrubbing plate device 400. This enables the solvent to more effectively break down stains and ensures a thorough cleaning. Furthermore, because the solvent covers the area to be cleaned, the floor brush assembly 10 can achieve sufficient spraying of the solvent without frequent movement or repositioning during the cleaning process, improving cleaning efficiency, reducing omissions and repetitive work, and ensuring a better user experience.

[0137] In some embodiments, referring to Figures 1 to 5, as well as Figures 8, 10, and 12, the driving device 500 includes a driving member 510 and a transmission member 520. The driving member 510 may include a drive motor and also has a rotatable output swing arm 511, which rotates under the drive of the drive motor to generate driving force.

[0138] The transmission member 520 is hinged to the output swing arm 511, and the transmission member 520 is adapted to slide along the width direction of the housing 100 under the drive of the output swing arm 511; either the wiping plate device 400 or the scraper device 300 is adapted to convert the sliding of the transmission member 520 along the width direction of the housing 100 into a vertical lifting motion.

[0139] Specifically, when the transmission component 520 slides along the width direction of the housing 100 under the drive of the output swing arm 511, the wiping plate device 400 or the scraper device 300 will rise or fall accordingly, thereby causing the wiping plate device 400 or the scraper device 300 to reach the working position 610 or the suspended position 620.

[0140] This design makes the floor brush assembly 10 more compact, reducing space occupation while improving the overall stability and durability of the machine. Furthermore, through the rotation of the drive component 510 and the sliding of the transmission component 520, the scrubbing plate device 400 or the scraper device 300 can be adjusted to a preset position to clean the floor. It is evident that the rotation of the drive component 510, the sliding of the transmission component 520, and the lifting and lowering design of the scrubbing plate device 400 or the scraper device 300 improve the cleaning efficiency and flexibility of the floor scrubber.

[0141] In some embodiments, referring to Figures 8 to 13, the transmission member 520 is provided with a first guide post 521 on the side facing the wiping device 400. The guide post not only serves to connect the transmission member 520 and the wiping device 400, but also guides the lifting and lowering movement of the wiping device 400 by sliding in a preset channel.

[0142] The wiping device 400 is provided with a first movable groove 410 extending through the front-rear direction of the housing 100. The first movable groove 410 includes a first horizontal section 411 extending along the width direction of the housing 100 and a first inclined section 412 inclined relative to the first horizontal section 411. The design of the first movable groove 410 allows the first guide post 521 to slide therein and drive the position of the wiping device 400 as the sliding position changes.

[0143] The first guide post 521 is inserted into the first movable slot 410. When the first guide post 521 is in the first horizontal section 411, the wiping plate device 400 is in the suspended position 620. When the first guide post 521 is in the first inclined section 412, the wiping plate device 400 performs lifting and lowering movements.

[0144] Specifically, when the first guide post 521 is in the first horizontal section 411 of the first movable groove 410, the wiping device 400 is in the suspended position 620. At this time, there is a certain gap between the wiping device 400 and the ground, which is convenient for storage. When the first guide post 521 slides from the first horizontal section 411 to the first inclined section 412, due to the existence of the first inclined section 412, the guide post slides along the first inclined section 412. At this time, the wiping device 400 descends to the preset position, i.e., the working position 610, under its own gravity. At this time, the wiping device 400 is in contact with the ground to achieve cleaning or wiping of the ground.

[0145] The combined use of the first guide post 521 and the first movable groove 410 makes the lifting and lowering movement of the wiping device 400 stable and smooth, reducing shaking and noise. In addition, since the first movable groove 410 includes a first horizontal section 411 and a first inclined section 412, the lifting speed and lifting stroke of the wiping device 400 can be adjusted by designing the inclination angle and length of the first inclined section 412.

[0146] It can be seen that by introducing the design of the first guide column 521 and the first movable groove 410, the transmission mechanism of the floor scrubber and the lifting movement of the scrubbing plate device 400 are optimized, which improves the stability and flexibility of the floor scrubber and ensures the cleaning efficiency of the floor scrubber.

[0147] In some embodiments, referring to Figures 1, 3, and 5, and Figures 8 to 13, the wiping plate device 400 includes a first movable plate 420 and a wiping plate member 430. The first movable plate 420 is one of the main components of the wiping plate device 400. A first movable groove 410 is formed in the first movable plate 420, and the first movable groove 410 is used to cooperate with a first guide post 521 on the transmission member 520 to realize the lifting and lowering movement of the wiping plate device 400.

[0148] The wiping plate 430 is detachably mounted at the bottom of the first movable plate 420. The wiping plate 430 directly contacts the surface to be cleaned and is used to perform wiping operations on the surface to be cleaned. This makes it easy for users to replace and clean the surface, improving the ease of use and maintainability of the floor scrubber.

[0149] Understandably, when the first guide post 521 on the transmission component 520 slides in the first movable groove 410, it drives the first movable plate 420 and the connected wiping plate component 430 to move up and down. This design allows the wiping plate component 430 to be adjusted to the working position 610 or the suspended position 620 according to usage requirements. When the wiping plate component 430 moves to the working position 610, it will contact the surface to be cleaned and perform a wiping operation.

[0150] It is evident that the cooperation between the first movable plate 420 and the first guide column 521 enhances the flexibility and convenience of using and storing the wiping plate component 430. Furthermore, the design of the wiping plate component 430 must consider ease of installation and disassembly to improve user convenience. Thus, by introducing the first movable plate 420 and the detachable wiping plate component 430, the flexibility and ease of use of the floor scrubber are improved, while its cleaning effect and maintainability are also optimized.

[0151] In some embodiments, referring to Figures 6 and 8 to 13, the transmission member 520 is provided with a second guide post 522 on the side facing the scraper device 300. Correspondingly, the second guide post 522, similar to the first guide post 521, serves to connect the transmission member 520 and the scraper device 300 and guide their lifting and lowering movements.

[0152] The scraper device 300 is provided with a second movable groove 310 that extends through the front-rear direction of the housing 100. That is, the scraper frame 320 is provided with the second movable groove 310. The second movable groove 310 includes a second horizontal section 311 extending along the width direction of the housing 100 and a second inclined section 312 inclined relative to the second horizontal section 311. The design of the second movable groove 310 allows the second guide post 522 to slide therein and adjust the position of the scraper device 300 according to the change of sliding position.

[0153] In this design, the projection of the intersection point of the second horizontal segment 311 and the second inclined segment 312 onto the intersection point of the first horizontal segment 411 and the first inclined segment 412 in the reference plane is opposite to the intersection point in the front-back direction. The reference plane is parallel to the surface to be cleaned. Thus, through the design of the intersection points, the wiping plate device 400 and the scraper device 300 are spatially distributed with relative arrangement on the reference plane (parallel to the surface to be cleaned), avoiding mutual interference and ensuring the smooth progress of the cleaning operation.

[0154] Specifically, this design is similar to the lifting mechanism of the wiping device 400. When the second guide column 522 is in the second horizontal section 311 of the second movable groove 310, the scraper device 300 is in the suspended position 620, at which time there is a certain gap between the scraper device 300 and the ground. When the second guide column 522 slides from the second horizontal section 311 to the second inclined section 312, due to the existence of the inclined section, the guide column slides along the second inclined section 312. At this time, the scraper device 300 descends to the preset position, i.e., the working position 610, under its own gravity. At this time, the scraper device 300 is in contact with the ground to achieve cleaning or scraping of the ground.

[0155] The combined use of the second guide post 522 and the second movable groove 310 makes the lifting and lowering movement of the scraper device 300 stable and smooth, reducing shaking and noise. In addition, since the second movable groove 310 includes a second horizontal section and a second inclined section, the lifting speed and lifting stroke of the scraper device 300 can be adjusted by designing the inclination angle and length of the inclined section.

[0156] The wiping plate device 400 and the scraper device 300 are connected to the transmission component 520 via the first guide post 521 and the second guide post 522, respectively, and achieve lifting and lowering movements via the first movable groove 410 and the second movable groove 310, respectively. This design allows the two to be controlled independently, improving the flexibility and cleaning efficiency of the floor scrubber. It also enables the floor scrubber to adapt to different floor surfaces and cleaning needs, allowing the lifting and lowering of the wiping plate device 400 or the scraper device 300 to be operated according to actual needs.

[0157] As can be seen, by introducing the second guide column 522 and the second movable groove 310, the transmission mechanism, the lifting and lowering movements of the scrubbing plate device 400 and the scraper device 300 of the floor scrubber are optimized, improving the stability and flexibility of the floor scrubber and ensuring its cleaning efficiency. Furthermore, the design of the first guide column 521, the first movable groove 410, the second guide column 522, and the second movable groove 310 enhances the compactness and flexibility of the floor scrubber.

[0158] In some embodiments, referring to Figures 8, 11, and 13, the second inclined segment 312 and the first horizontal segment 411 are opposite each other along the front-rear direction of the housing 100. This design means that when the second guide post 522 on the transmission member 520 slides on the second inclined segment 312, the position of the wiping device 400 on the first horizontal segment 411 is corresponding, but the two are in different lifting states. Furthermore, the projection lengths of the second inclined segment 312 and the first horizontal segment 411 in the reference plane are equal. This design ensures that the wiping device 400 and the scraper device 300 have similar ranges of motion during lifting, and when one of them is fully lowered to the working position 610, the other is locked in the suspended position 620.

[0159] The second horizontal segment 311 and the first inclined segment 412 are opposite each other along the front-rear direction of the housing 100. This design means that when the second guide post 522 on the transmission member 520 slides on the second horizontal segment 311, the position of the scraper device 300 is corresponding to that of the first inclined segment 412, but the two are in different lifting states. Furthermore, the projection lengths of the second horizontal segment 311 and the first inclined segment 412 in the reference plane are equal. This design further ensures that the wiping plate device 400 and the scraper device 300 have similar ranges of motion during lifting.
