Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and in particular to a floor brush assembly and a floor scrubber. Background Technology

[0002] Floor scrubbers, as efficient floor cleaning equipment, have become a common tool for floor cleaning in both residential and commercial settings. The floor brush assembly, a key component for achieving effective cleaning, uses its squeegee to remove residual dirt and grime from the floor as the machine moves forward, improving its cleanliness.

[0003] Traditional floor scrubbers typically have a rear scraper at the rear of the roller brush. While the rear scraper removes dirt when the machine moves forward, it can leave dirt residue when the machine reverses. To address this, some modern floor scrubbers have added a front scraper at the front of the roller brush. The combination of the front and rear scrapers effectively improves the problem of dirt residue during reverse movement, enabling bidirectional cleaning in both forward and reverse directions.

[0004] However, in existing technologies, the front squeegee of the floor scrubber is directly exposed in the cleaning path and continuously in contact with dirt on the ground. The surface of the squeegee is easily covered with dirt, which not only reduces the adhesion between the squeegee and the ground and weakens the squeegee's cleaning effect, but also becomes a new source of pollution in subsequent cleaning processes, causing secondary pollution of the ground and seriously affecting the cleaning effect of the floor scrubber.

Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or terminal device that includes said element.

[0026] The following detailed description of a floor brush assembly and floor scrubber provided in this application is illustrated with specific embodiments.

[0027] Reference Figures 1 to 6 The floor brush assembly provided in this application embodiment has intersecting length, width, and height directions, and the floor brush assembly includes: The housing 1 has a first cavity 11; The roller brush 2 is rotatably disposed on the housing 1 and located below the first cavity 11 along the height direction; The scraper 3 is movably disposed in the first cavity 11, and a portion of the scraper 3 extends out of the first cavity 11 and is placed on the front side of the roller brush 2 along its length. The driving component 4 is movably disposed in the first cavity 11 and connected to the scraper 3; the driving component 4 is used to drive the scraper 3 to move relative to the housing 1 in a first direction, so that the scraper 3 is in a working position that abuts against the surface to be cleaned and in a suspended position that is separated from the surface to be cleaned. The spray assembly is movably disposed in the first cavity 11 and is configured to be linked with the drive member 4. When the scraper member 3 is in the working position, the spray assembly sprays cleaning liquid toward the scraper member 3.

[0028] Specifically, the floor brush assembly has intersecting length, width, and height directions, such as... Figures 1 to 4As shown, the length direction corresponds to the front-to-back direction, the width direction corresponds to the left-to-right direction, and the height direction corresponds to the up-to-down direction. The front side of the floor brush assembly along its length is the side that first contacts the surface to be cleaned when the floor scrubber moves forward during cleaning, and the rear side along its length is the side that first contacts the surface to be cleaned when the floor scrubber moves backward during cleaning. The width direction of the floor brush assembly is parallel to the surface to be cleaned, and there are no specific limitations on the left and right sides of the width direction. The height direction of the floor brush assembly is perpendicular to or nearly perpendicular to the surface to be cleaned. The upper side of the height direction is used to connect with the handle or main body of the floor scrubber to realize the power transmission and command transmission between the floor brush assembly and the whole machine. The lower side of the height direction is the working end, which is equipped with functional components such as roller brush 2 and scraper 3, and is used to directly contact the surface to be cleaned to complete the cleaning operation. In this embodiment, the surface to be cleaned includes various types such as floors, walls, countertops, and boards, and there are no specific limitations in this embodiment.

[0029] The housing 1 serves as the main support structure for the floor brush assembly, supporting functional components such as the roller brush 2, drive unit 4, scraping component 3, and spray assembly. Figure 3 and Figure 4 As shown, a first cavity 11 is formed inside the housing 1, and the scraping component 3, the driving component 4, and the spraying assembly are all movably disposed in the first cavity 11. The roller brush 2 is rotatably disposed on the housing 1 and located below the first cavity 11 along the height direction. For example, the roller brush 2 is rotatably mounted on the inner side of the housing 1 through bearing seat assemblies at both ends, and the roller brush 2 is positioned below the first cavity 11 along the height direction. The rotation direction of the roller brush 2 is adapted to the travel direction of the floor scrubber, and it can remove dirt from the surface to be cleaned by high-speed rotation.

[0030] The housing 1 has an opening on its front side along its length, the extension direction of which is parallel to the axial direction of the roller brush 2, where the axial direction of the roller brush 2 refers to the direction of its central axis. The opening communicates with the first cavity 11, and a portion of the scraping member 3 can extend from the opening into the first cavity 11 and be positioned on the front side of the roller brush 2 along its length. The driving member 4 is movably connected to the housing 1 and can move relative to the housing 1. Simultaneously, the driving member 4 is connected to the scraping member 3, and during its movement relative to the housing 1, the driving member 4 can drive the scraping member 3 to move synchronously. For example, the driving member 4 can be a slider, and a guide rail is provided on the cavity wall of the first cavity 11. The slider and the guide rail are fitted and engaged, forming a sliding guide structure. The slider can slide along the guide rail, thereby achieving movement relative to the housing 1. The scraping member 3 is connected to the slider, and during the sliding of the slider along the guide rail, it can drive the scraping member 3 to move synchronously.

[0031] The scraper 3 can be fixedly connected to the drive component 4 through assembly, snap-fit, or other methods. In this connection method, the scraper 3 and the drive component 4 are rigidly connected, and their movement directions are completely consistent. When the drive component 4 moves relative to the housing 1 along a preset trajectory, the scraper 3 moves synchronously with the drive component 4, and the area of ​​the part of the scraper 3 extending outside the first cavity 11 changes accordingly, thereby achieving the switching between the working position and the suspended position. The scraper 3 can also be movably connected to the drive component 4. In this connection method, the movement directions of the scraper 3 and the drive component 4 can be the same or different, which can better adapt to the needs of complex cleaning scenarios.

[0032] like Figure 3 and Figure 4 As shown, in this embodiment, the scraper 3 and the drive 4 are rotatably connected. The drive 4 reciprocates linearly in the front-back direction, and the scraper 3 is rotatably connected to the drive 4 via a rotating shaft. The extension direction of this rotating shaft is parallel to the axial direction of the roller brush 2. When the drive 4 moves in the front-back direction, it directly drives the scraper 3 to move synchronously in the front-back direction. On the other hand, the scraper 3 can rotate relative to the drive 4 around the rotating shaft at a certain angle. During the rotation, the area of ​​the part of the scraper 3 extending outside the first cavity 11 is adjusted accordingly, thereby realizing the switching between the working position and the suspended position. In this embodiment, the direction of movement of the scraper 3 relative to the housing 1 is defined as the first direction. It can be understood that the first direction is not a linear direction, but can be understood by analogy as a clockwise or counterclockwise direction. The first direction has a certain angle with the front-back direction and also has a certain angle with the height direction.

[0033] Among them, such as Figure 3 As shown, when the drive member 4 moves forward in the front-back direction, the drive scraper 3 rotates around the axis towards the roller brush 2. The area of ​​the part of the scraper 3 extending out of the first cavity 11 gradually increases, and the scraper 3 comes into close contact with the surface to be cleaned. At this time, the scraper 3 is in the working position and can effectively scrape off the dirt on the surface to be cleaned.

[0034] like Figure 4 As shown, when the drive member 4 moves backward in the front-back direction, it drives the scraper 3 to rotate around the axis away from the roller brush 2. The area of ​​the part of the scraper 3 extending out of the first cavity 11 gradually decreases, and the scraper 3 separates from the surface to be cleaned. The two do not contact each other. At this time, the scraper 3 is in a suspended position, which can avoid wear caused by the scraper 3 contacting the surface to be cleaned during the non-cleaning stage.

[0035] The spray assembly is configured to work in conjunction with the drive unit 4. When the scraper 3 is in the working position against the surface to be cleaned, the spray assembly can spray cleaning fluid towards the scraper 3. Because dirt easily accumulates on the surface of the scraper 3 during long-term cleaning operations, this not only reduces the adhesion between the scraper 3 and the surface to be cleaned, weakening the scraping effect, but also becomes a new source of contamination in subsequent cleaning processes, causing secondary contamination of the surface to be cleaned. In this application, the spray assembly sprays cleaning fluid onto the scraper 3 when it is in the working position. The cleaning fluid quickly soaks into the dirt adhering to the surface of the scraper 3, reducing its adhesion and allowing it to be carried away with the cleaning fluid during the cleaning process. This prevents dirt buildup on the scraper 3, maintaining its cleanliness, ensuring proper contact between the scraper 3 and the surface, improving its scraping effect, and preventing secondary contamination of the floor during subsequent cleaning. Furthermore, the spray assembly is linked to the drive unit 4. As the drive unit 4 moves the scraper 3, the spray assembly moves synchronously, enabling real-time linkage between the spraying and scraping actions. This reduces the response delay between the two actions and ensures the continuity of the cleaning operation.

[0036] Optionally, in some embodiments of this application, reference is made to Figure 3 and Figure 4 The spray assembly includes a linkage mechanism 5 and a nozzle 6. The linkage mechanism 5 is connected to the drive member 4, and the nozzle 6 is connected to the linkage mechanism 5. The nozzle 6 extends out of the first cavity 11 and is positioned on the front side of the roller brush 2 along its length. The drive member 4 is used to drive the linkage mechanism 5 to move. The linkage mechanism 5 drives the nozzle 6 to move relative to the housing 1, so that the nozzle 6 is in a first position or a second position. When the scraper 3 is in the working position, the nozzle 6 is in the first position, and the outlet 61 of the nozzle 6 faces the scraper 3. When the scraper 3 is in the suspended position, the nozzle 6 is in the second position, and the outlet 61 of the nozzle 6 faces the surface to be cleaned.

[0037] Specifically, the power input end of the linkage mechanism 5 is connected to the drive component 4, and the power output end of the linkage mechanism 5 is fixedly connected to the nozzle 6. It can be understood that the linkage mechanism 5 has an internal flow channel for the flow of cleaning fluid, which is connected to the inlet of the nozzle 6. The nozzle 6 extends out of the first cavity 11 from the opening of the housing 1 and is located in front of the roller brush 2. The nozzle 6 can be located between the roller brush 2 and the scraper 3, or it can be located on the side of the scraper 3 away from the roller brush 2, ensuring that the outlet 61 of the nozzle 6 faces the scraper 3.

[0038] During the process of driving the scraper 3 to switch between the working position and the suspended position, the driving component 4 can synchronously drive the linkage mechanism 5 to move, so that the linkage mechanism 5 is in different postures. During the movement of the linkage mechanism 5, the nozzle 6 moves synchronously, so that the nozzle 6 moves to the first position or the second position, thereby realizing the adaptive adjustment of the cleaning liquid spraying direction.

[0039] like Figure 3 As shown, when the driving component 4 moves forward in the front-to-back direction, it drives the scraper 3 to rotate towards the roller brush 2. The area of ​​the portion of the scraper 3 extending outside the first cavity 11 gradually increases, eventually bringing the scraper 3 into close contact with the surface to be cleaned in the working position. During this process, the linkage mechanism 5 drives the nozzle 6 to move to the first position, at which point the outlet 61 of the nozzle 6 faces the scraper 3. For example, as... Figure 6 As shown, the water outlet 61 of the nozzle 6 is positioned directly opposite the scraper 3. The cleaning liquid is sprayed onto the surface of the scraper 3 through the water outlet 61 of the nozzle 6, which can quickly wet the dirt attached to the surface of the scraper 3, reduce the adhesion of the dirt, and allow the dirt to detach from the surface of the scraper 3 as the cleaning operation progresses. This helps to maintain the cleanliness of the scraper 3, improves the scraping effect of the scraper 3, and also avoids secondary pollution of the ground during subsequent cleaning processes.

[0040] like Figure 4 As shown, when the driving component 4 moves backward in the front-to-back direction, it drives the scraping component 3 to rotate away from the roller brush 2. The area of ​​the part of the scraping component 3 extending outside the first cavity 11 gradually decreases, eventually causing the scraping component 3 to separate from the surface to be cleaned and be in a suspended position. During this process, the linkage mechanism 5 drives the nozzle 6 to move to the second position, at which point... Figure 5 As shown, the water outlet 61 of nozzle 6 faces the surface to be cleaned. The cleaning liquid can be sprayed directly onto the surface to be cleaned, which can pre-wet the stubborn stains on the surface to be cleaned, providing good conditions for the subsequent rotating cleaning operation of roller brush 2 and improving the cleaning effect of roller brush 2 on dirt.

[0041] In this embodiment, a linkage mechanism 5 is used as the power transmission medium, directly connected to the drive component 4. While the drive component 4 drives the scraper 3 to switch between working and suspended positions, the linkage mechanism 5 can simultaneously pull the nozzle 6 to complete position adjustment. The linkage mechanism 5 and the drive component 4 operate in tandem without signal transmission or component start-stop processes, achieving zero-delay matching between the positions of the scraper 3 and the nozzle 6. This ensures that the nozzle 6 is precisely in the first position when the scraper 3 is working, and that the nozzle 6 can promptly turn towards the surface to be cleaned when the scraper 3 is suspended, guaranteeing the continuity of the cleaning operation. Simultaneously, the transmission method of the linkage mechanism 5 has strong anti-interference capabilities and is not easily affected by the humid environment or corrosion of the cleaning fluid within the first cavity 11, thus contributing to a longer service life.

[0042] Optionally, in some embodiments of this application, reference is made to Figure 3 and Figure 4 The linkage mechanism 5 includes a first link 51 and a second link 52; the first link 51 is rotatably connected to the housing 1, one end of the first link 51 is hinged to the drive member 4, and the other end of the first link 51 is hinged to the second link 52; the nozzle 6 is connected to the end of the second link 52 away from the first link 51; the drive member 4 is used to drive the first link 51 to rotate relative to the housing 1, and the first link 51 drives the second link 52 and the nozzle 6 to move so that the nozzle 6 is in a first position or a second position.

[0043] Specifically, the linkage mechanism 5 adopts a double-link linkage structure, including a first link 51 and a second link 52. Both the first link 51 and the second link 52 have internal channels for the flow of cleaning fluid. The internal channel of the first link 51 is connected to the internal channel of the second link 52, and the internal channel of the second link 52 is connected to the inlet of the nozzle 6. Sealing joints are provided at the connection points between the internal channels of the first link 51 and the second link 52, and at the connection points between the internal channel of the second link 52 and the inlet of the nozzle 6, to ensure the sealing of the cleaning fluid delivery. The first link 51 and the second link 52 can be made of plastic or lightweight alloy. The inner walls of the internal channels of the first link 51 and the second link 52 can be treated with an anti-corrosion coating to improve the corrosion resistance of the channels and prevent scaling or rust. The first link 51 and the second link 52 are connected by a revolute joint. When the first link 51 rotates relative to the housing 1, the included angle between the first link 51 and the second link 52 will change accordingly. That is, the overall posture of the linkage mechanism 5 will change accordingly, thereby realizing the conversion of the force of the driving member 4 to the direction of transmission to the nozzle 6. For example, the housing 1 is provided with a connecting shaft or connecting hole, and the first link 51 is provided with a matching connecting hole or connecting shaft. The first link 51 is rotatably connected to the housing 1 by means of shaft-hole cooperation, forming the fulcrum for the rotation of the first link 51 relative to the housing 1.

[0044] One end of the first connecting rod 51 is the power input end, which is hinged to the drive member 4. When the drive member 4 moves in the front-back direction in the first cavity 11, it will drive the first connecting rod 51 to rotate around the aforementioned fulcrum, which is equivalent to the first connecting rod 51 swinging in the first cavity 11. The other end of the first connecting rod 51 is the power output end, which is hinged to one end of the second connecting rod 52, driving the second connecting rod 52 to move. The end of the second connecting rod 52 away from the first connecting rod 51 is the actuating end, which is fixedly connected to the nozzle 6. The nozzle 6 extends out of the first cavity 11 from the opening of the housing 1 and is located on the front side of the roller brush 2. Thus, the second connecting rod 52 drives the nozzle 6 to move, so that the nozzle 6 is in the first position or the second position.

[0045] like Figure 3As shown, when the drive unit 4 moves forward in the front-back direction, it drives the scraper 3 to rotate towards the roller brush 2. The area of ​​the part of the scraper 3 extending out of the first cavity 11 gradually increases, eventually bringing the scraper 3 into close contact with the surface to be cleaned in the working position. During the process, the drive unit 4 synchronously drives the first connecting rod 51 to rotate around the fulcrum relative to the housing 1. The end of the first connecting rod 51 connected to the drive unit 4 moves forward synchronously with the drive unit 4, while the end of the first connecting rod 51 connected to the second connecting rod 52 swings in the opposite direction, causing the second connecting rod 52 to rise, so that the nozzle 6 moves to the first position. At this time, the water outlet 61 of the nozzle 6 faces the surface of the scraper 3, and the cleaning liquid is sprayed onto the surface of the scraper 3 through the water outlet 61 of the nozzle 6, thus cleaning the dirt on the surface of the scraper 3.

[0046] like Figure 4 As shown, when the drive unit 4 moves backward in the front-to-back direction, it drives the scraper 3 to rotate away from the roller brush 2. The area of ​​the part of the scraper 3 extending outside the first cavity 11 gradually decreases, eventually causing the scraper 3 to separate from the surface to be cleaned and be in a suspended position. During the process, the drive unit 4 synchronously drives the first connecting rod 51 to rotate around the fulcrum relative to the housing 1. The end of the first connecting rod 51 connected to the drive unit 4 moves backward synchronously with the drive unit 4, while the end of the first connecting rod 51 connected to the second connecting rod 52 swings in the opposite direction, causing the second connecting rod 52 to descend, so that the nozzle 6 moves to the second position. At this time, the water outlet 61 of the nozzle 6 faces the surface to be cleaned, realizing the pre-wetting treatment of the surface to be cleaned.

[0047] This embodiment utilizes the transmission characteristics of a double-link linkage to synchronously drive the switching of the nozzle 6 position and the switching of the scraping component 3 through the same drive component 4. This eliminates the need for an additional independent power source, significantly simplifying the structural design of the floor brush assembly, reducing the number of components required, and helping to control the production cost of the floor brush assembly. Simultaneously, the floor brush assembly of this embodiment can achieve real-time linkage between spraying and scraping actions, greatly shortening the response delay between the two actions and ensuring the continuity of cleaning operations.

[0048] Of course, in some embodiments, the linkage mechanism 5 can also be a multi-link mechanism, adding transition links, guide links, etc., to the first link 51 and the second link 52. For example, the transition link serves as a power transmission intermediary, connecting the first link 51 and the second link 52, and is hinged to the first link 51 and the second link 52 respectively. The transition link can optimize the power transmission angle and avoid interference between the first link 51 and the second link 52 due to excessive swing angle. It should be noted that the transition link also needs to adopt a hollow rod structure, with its internal flow channel connected to the flow channels inside the first link 51 and the second link 52, and the connection part is provided with a sealing joint to ensure the sealing of the cleaning fluid delivery. One end of the guide link can be hinged to the middle of the second link 52, and the other end is slidably connected to the guide groove preset on the housing 1, forming an auxiliary guide fulcrum for the second link 52, restricting the movement trajectory of the second link 52, improving the stability of the movement process of the second link 52, thereby ensuring that the nozzle 6 can accurately reach the first position or the second position.

[0049] Optionally, in some embodiments of this application, reference is made to Figure 3 and Figure 4 The second connecting rod 52 extends along the first direction, and the movement direction of the nozzle 6 is opposite to the movement direction of the scraper 3. Specifically, the second connecting rod 52 extends along the first direction, meaning its arrangement is parallel to the direction of movement of the scraper 3 relative to the housing 1. The second connecting rod 52 can be configured as a flexible rod, such as a polyurethane elastic rod or a carbon fiber flexible connecting rod, utilizing its own elastic deformation capability to adapt to the linkage movement of the scraper 3 and the drive component 4, buffering the impact force during movement, and reducing the risk of breakage of the second connecting rod 52.

[0050] Nozzle 6 is connected to the end of the second link 52. The movement direction of nozzle 6 is opposite to that of scraper 3. This allows the second link 52 and scraper 3 to form a reverse clearance space during movement. When scraper 3 moves downward toward the surface to be cleaned, nozzle 6 moves upward away from the surface to be cleaned; when scraper 3 moves upward away from the surface to be cleaned, nozzle 6 moves downward toward the surface to be cleaned. The movement trajectories of the two do not intersect or overlap, effectively avoiding collisions or jamming between scraper 3 and nozzle 6 when switching positions. This adapts to the narrow installation space inside the first cavity 11 and improves the compactness and reliability of the overall structure.

[0051] Optionally, in some embodiments of this application, reference is made to Figure 3 and Figure 4The first connecting rod 51 is provided with a rotating part 511, which is rotatably connected to the housing 1; wherein the rotating part 511 is located close to the second connecting rod 52. The rotating part 511 is equivalent to the fulcrum for the rotation of the first connecting rod 51 relative to the housing 1. It is located close to the second connecting rod 52, so that the lever arm length from the end of the first connecting rod 51 connected to the driving member 4 to the fulcrum is greater than the lever arm length from the end of the first connecting rod 51 connected to the second connecting rod 52 to the fulcrum. That is, the lever arm length from the power input end of the first connecting rod 51 to the fulcrum is greater than the lever arm length from the power output end of the first connecting rod 51 to the fulcrum. According to the lever principle, when the driving member 4 drives the power input end of the first connecting rod 51 to make a small amplitude movement, the power output end of the first connecting rod 51 can make a larger amplitude movement, thereby increasing the range of motion of the second connecting rod 52. This allows the second connecting rod to drive the nozzle 6 to make a larger amplitude swing, thereby increasing the switching distance of the nozzle 6 between the first position and the second position. This ensures that the spraying direction of the nozzle 6 in the two positions does not overlap or interfere, and better adapts to the dual needs of cleaning by the scraper 3 and pre-treatment of the surface to be cleaned.

[0052] In addition, when the rotating part 511 is positioned close to the second link 52, it helps to make the swing of the second link 52 more stable and less prone to large deviations or shaking, thereby improving the stability of the nozzle 6 during movement and ensuring that the nozzle 6 can accurately align with the surface of the scraper 3 when in the first position and accurately align with the surface to be cleaned when in the second position, thus avoiding waste or reduced cleaning effect caused by misalignment of the cleaning liquid spray.

[0053] In addition, the short lever arm design can significantly reduce the driving force required for the drive component 4 to drive the first link 51 to move, thereby reducing the frictional loss between the drive component 4 and the guide rail inside the housing 1, avoiding problems such as jamming and abnormal noise during the movement of the drive component 4, and improving the stability of the drive component 4 and the linkage mechanism 5 during operation.

[0054] Optionally, in some embodiments of this application, reference is made to Figure 3 and Figure 4 There are two first links 51, which are connected to opposite sides of the drive member 4 along the width direction; there are at least two second links 52, and each first link 51 is connected to at least one second link 52.

[0055] Specifically, two first connecting rods 51 are distributed opposite each other on both sides of the drive member 4 along the width direction. The rotating part 511 of each of the two first connecting rods 51 is rotatably connected to the housing 1. When the drive member 4 moves in the front-back direction within the first cavity 11, it can synchronously drive the two first connecting rods 51 to swing in the same direction and with the same amplitude around their respective rotating parts 511, thereby driving the second connecting rod 52 and the nozzle 6 to move synchronously. The above-mentioned symmetrical drive method can counteract the deflection torque generated when the first connecting rod 51 on one side is subjected to force, reduce the possibility of the second connecting rod 52 and the nozzle 6 tilting or wobbling during the movement, and improve the stability of the movement of the second connecting rod 52 and the nozzle 6.

[0056] The number of second links 52 is two or more, and each first link 51 is connected to at least one second link 52. Figure 3 and Figure 4 The diagram illustrates how each first link 51 connects to one second link 52. Of course, each first link 51 can also connect to two or more second links 52, spaced apart along the width direction. Each second link 52 has a nozzle 6 connected to its end opposite to the first link 51. In other words, the number of second links 52 determines the number of nozzles 6. In practical applications, the number of second links 52 and nozzles 6 can be flexibly set according to the width dimension of the scraper 3. A larger width dimension of the scraper 3 allows for a greater number of second links 52 and nozzles 6, while a smaller width dimension allows for a smaller number of second links 52 and nozzles 6. Furthermore, the spacing between adjacent nozzles 6 can be the same or different. For example, if dirt tends to accumulate near the center of the scraper 3, the nozzles 6 near the center can be spaced closer together, resulting in a higher density.

[0057] In this way, the floor brush assembly of this embodiment can adapt to the requirement of multiple nozzles 6 arranged in parallel. The multiple nozzles 6 can spray cleaning liquid towards different areas of the scraper 3 or different areas of the surface to be cleaned, according to the cleaning needs. For example, when the scraper 3 is in the working position, multiple nozzles 6 can spray cleaning liquid onto the surface of the scraper 3 at the same time to achieve comprehensive cleaning of the surface of the scraper 3. When the scraper 3 is in the suspended position, multiple nozzles 6 can spray cleaning liquid onto the surface to be cleaned at the same time, and the cleaning liquid can cover a larger area of ​​the surface to be cleaned, greatly improving cleaning efficiency.

[0058] Optionally, in some embodiments of this application, reference is made to Figure 3 and Figure 4At least two second connecting rods 52 are symmetrically distributed on both sides of the drive member 4 along the width direction. This arrangement ensures that the first connecting rod 51 and the second connecting rod 52 on the left side of the drive member 4 are symmetrically distributed with the first connecting rod 51 and the second connecting rod 52 on the right side of the drive member 4, forming a symmetrical force-bearing structure. When the drive member 4 outputs power, the first connecting rods 51 and the second connecting rod 52 on both sides generate forces of equal magnitude, which helps to counteract the off-center load torque generated when the connecting rods on one side are subjected to force, thereby further improving the stability of the first connecting rod 51, the second connecting rod 52 and the nozzle 6 during the movement process.

[0059] In addition, the second link 52 is symmetrically distributed on both sides of the drive member 4 along the width direction, which helps to keep the center of gravity of the link mechanism 5 on the central axis of the housing 1 along the width direction. During the cleaning operation of the floor brush assembly, the symmetrical distribution of the center of gravity helps to ensure that the roller brush 2, the scraping part 3 and other parts in the floor brush assembly are fully in contact with the surface to be cleaned, avoids the floor brush assembly from swaying left and right, and improves the consistency of the cleaning effect.

[0060] In addition, the symmetrically distributed linkage mechanism 5 has a stronger resistance to lateral impact. When the floor brush assembly is working on uneven ground, the lateral impact force on the floor brush assembly can be evenly distributed by the linkages on both sides of the drive component 4, avoiding deformation or breakage of the linkage on one side due to overload. This allows the linkage mechanism 5 to better adapt to complex cleaning conditions and improve the structural reliability of the floor brush assembly.

[0061] Optionally, in some embodiments of this application, reference is made to Figure 3 and Figure 4 The cleaning component 3 includes a transmission plate 31 and a scraper 32; the transmission plate 31 is connected to the drive component 4, and the scraper 32 is detachably connected to the side of the transmission plate 31 away from the drive component 4; the scraper 32 extends out of the first cavity 11 and is used to abut or separate from the surface to be cleaned.

[0062] Specifically, the scraping component 3 can adopt a split assembly structure, including two parts: a transmission plate 31 and a scraper 32. The transmission plate 31 can be a rigid structural component, requiring sufficient structural strength, deformation resistance, and wear resistance to stably transmit the power of the drive component 4 and adapt to the working conditions of movement within the first cavity 11. For example, the transmission plate 31 can be made of reinforced nylon, hard ABS engineering plastic, or stainless steel sheet. The rear side of the transmission plate 31 is fixedly connected to or hinged to the drive component 4 to transmit the power provided by the drive component 4 to the scraper 32. The scraper 32 is connected to the side of the transmission plate 31 away from the drive component 4 by bolts, snap-fit, or other means, and the scraper 32 extends out of the first cavity 11 from the opening of the housing 1 to directly contact or separate from the surface to be cleaned. The scraper blade 32 can be made of flexible and wear-resistant parts, such as elastic wear-resistant rubber or polyurethane, which has excellent deformation ability and wear resistance. It can closely fit the surface to be cleaned with different flatness, improve the scraping efficiency, and is resistant to cleaning fluid corrosion, making it suitable for humid working environments.

[0063] The scraping component 3 adopts the structure of this embodiment. The transmission plate 31, as a rigid connecting member, can transmit the power provided by the drive component 4 to the scraper 32 with almost no loss, ensuring that the scraper 32 can move relatively accurately along the first direction and switch to the working position or the suspended position, thereby ensuring the stability and reliability of the cleaning operation. In addition, the scraper 32 is detachably connected to the transmission plate 31. As a vulnerable component that directly contacts dirt, the scraper 32 is prone to wear and aging after long-term use. Therefore, the scraper 32 can be removed from the transmission plate 31 for replacement without replacing the entire scraping component 3. Since the transmission plate 31 is located inside the first cavity 11, it is subject to relatively less wear, and its service life is much longer than that of the scraper 32. Therefore, the transmission plate 31 can be reused, which greatly reduces the later maintenance cost of the floor brush assembly. In addition, the scraper 32 is detachably connected to the transmission plate 31, and different specifications of scraper 32 can be replaced according to different cleaning scenarios, such as scraper 32 with different hardness, different texture, and different width, without the need to adjust other parts, thereby improving the functional adaptability and versatility of the floor brush assembly.

[0064] Optionally, in some embodiments of this application, reference is made to Figure 3 and Figure 4The transmission plate 31 is provided with a positioning hole 311, and the second connecting rod 52 is movably inserted through the positioning hole 311, and the second connecting rod 52 passes through the transmission plate 31 along the first direction. The positioning hole 311 extends in the same direction as the first direction and passes through both sides of the transmission plate 31 along the first direction. The second connecting rod 52 passes through the positioning hole 311, and a fitting gap is reserved between the second connecting rod 52 and the hole wall of the positioning hole 311 to ensure that the second connecting rod 52 can slide smoothly within the positioning hole 311. The positioning hole 311 guides and limits the movement of the second connecting rod 52, which helps to prevent the second connecting rod 52 from lateral deviation during movement, thereby further improving the stability of the movement of the second connecting rod 52 and driving the nozzle 6 to accurately be in the first or second position.

[0065] Furthermore, a wear-resistant bushing, such as a polytetrafluoroethylene bushing, can be embedded in the inner wall of the positioning hole 311. The inner hole size of the bushing is adapted to the outer diameter of the second connecting rod 52. In this way, the frictional loss between the second connecting rod 52 and the positioning hole 311 can be reduced, and the guiding accuracy of the positioning hole 311 for the second connecting rod 52 can be improved, ensuring the stability of the second connecting rod 52 when driving the nozzle 6.

[0066] Furthermore, the second connecting rod 52 passes through the positioning hole 311 of the transmission plate 31, which makes full use of the thickness of the transmission plate 31. This helps to reduce the space occupied by the connecting rod mechanism 5 in the first cavity 11, leaving more installation space for other components such as the roller brush 2 and cleaning fluid pipeline, and better adapting to the miniaturized design requirements of the floor brush assembly. At the same time, it can also prevent the second connecting rod 52 from interfering with the transmission plate 31 and the scraper 32 during the movement, ensuring the reliability of the floor brush assembly.

[0067] Optionally, in some embodiments of this application, reference is made to Figure 3 and Figure 4 The floor brush assembly also includes a liquid storage tank 7; the housing 1 also has a second cavity 12, which is arranged side by side with the first cavity 11 along the length direction; the liquid storage tank 7 is located in the second cavity 12, and the drive component 4 has a hollow cavity, and the liquid storage tank 7 is connected to the hollow cavity of the drive component 4; the liquid storage tank 7, the drive component 4, the linkage mechanism 5, and the nozzle 6 together form a cleaning liquid delivery channel.

[0068] Specifically, the storage tank 7 is used to store cleaning fluid. The shell 1 adopts a chamber design. In addition to the first chamber 11 that carries the drive component 4, the scraper component 3, and the spray assembly, a second chamber 12 is also formed. The storage tank 7 is located in the second chamber 12. The second chamber 12 and the first chamber 11 are arranged side by side along the length of the shell 1. The two are isolated by the partition wall inside the shell 1 to prevent the cleaning fluid from leaking into the first chamber 11 and affecting the movement stability of the drive component 4, the scraper component 3, and the spray assembly.

[0069] The storage tank 7 is sealed and embedded in the second cavity 12. The outlet of the storage tank 7 is connected to the hollow cavity inside the drive component 4 through the infusion pipe 71. The infusion pipe 71 can be a corrosion-resistant flexible hose to avoid corrosion of the infusion pipe 71 by the cleaning fluid. The hollow cavity inside the drive component 4 extends through both ends along the movement direction of the drive component 4, forming a transfer and delivery channel for the cleaning fluid. Furthermore, the hollow cavity of the drive component 4 is connected to the internal flow channels of each of the first connecting rods 51 and the second connecting rods 52 through branch pipes. The cleaning fluid is delivered to the inlet of the nozzle 6 through the flow channel of the second connecting rod 52 and finally sprayed out from the outlet 61 of the nozzle 6. This creates a series of cleaning fluid delivery channels: from the storage tank 7 to the hollow cavity of the drive component 4, from the hollow cavity of the drive component 4 to the internal flow channel of the first connecting rod 51, from the internal flow channel of the first connecting rod 51 to the internal flow channel of the second connecting rod 52, and from the internal flow channel of the second connecting rod 52 to the nozzle 6, achieving stable, directional, and quantitative delivery of the cleaning fluid. Each connection point of the flow channels is equipped with a sealing joint to ensure the airtightness of the cleaning fluid delivery.

[0070] This embodiment utilizes the hollow cavity of the drive component 4 as a transfer channel for the cleaning fluid, eliminating the need for separate delivery pipelines. By integrating the power transmission component and the fluid delivery component into one unit, the internal structure of the floor brush assembly is significantly simplified, making it more suitable for the miniaturized and lightweight design of floor scrubbers. Simultaneously, the cleaning fluid delivery channel adopts a closed design. This prevents leakage of the cleaning fluid during delivery, which could cause short circuits in other electronic components within the housing 1. Furthermore, it prevents external dust and dirt from entering the cleaning fluid delivery channel, avoiding pipe blockages or poor spraying.

[0071] Optionally, in some embodiments of this application, reference is made to Figures 2 to 4 The floor brush assembly also includes a control module and a control valve 8; the control module is electrically connected to the drive component 4 and is used to control the movement of the drive component 4 relative to the housing 1; the control valve 8 is electrically connected to the control module and is connected to the cleaning fluid delivery channel, and is used to control the opening and closing of the cleaning fluid delivery channel.

[0072] Specifically, in this embodiment, the control valve 8 can be a solenoid valve, which has high control precision, can achieve quantitative adjustment of the cleaning fluid flow rate, and has excellent sealing performance, effectively preventing cleaning fluid leakage. Figure 1 As shown, the floor brush assembly also includes a sensor wheel 9, which is used to detect the direction of movement of the floor scrubber, such as whether the floor scrubber is moving forward or backward. The control module is electrically connected to the sensor wheel 9 and can control the action of the drive unit 4 and the opening and closing of the solenoid valve according to the signal detected by the sensor wheel 9.

[0073] like Figure 3As shown, when the floor scrubber moves backward, the sensing wheel 9 detects the backward signal, and the control module controls the drive component 4 to move forward, driving the scraper 3 to rotate towards the roller brush 2. The area of ​​the part of the scraper 3 extending outside the first cavity 11 gradually increases, eventually bringing the scraper 3 into close contact with the surface to be cleaned and into the working position. During this process, the drive component 4 synchronously drives the first connecting rod 51 to rotate relative to the housing 1 around the fulcrum. The end of the first connecting rod 51 connected to the drive component 4 moves forward synchronously with the drive component 4, while the end of the first connecting rod 51 connected to the second connecting rod 52 swings in the opposite direction, causing the second connecting rod 52 to rise, so that the nozzle 6 moves to the first position. At this time, the water outlet 61 of the nozzle 6 faces the surface of the scraper 3. When the scraper 3 is in the working position, the control module controls the solenoid valve to open, opening the cleaning liquid delivery channel, so that the cleaning liquid is sprayed onto the surface of the scraper 3 through the water outlet 61 of the nozzle 6, thereby cleaning the dirt on the surface of the scraper 3.

[0074] like Figure 4 As shown, when the floor scrubber moves forward, the sensing wheel 9 detects the forward signal, and the control module controls the drive component 4 to move backward, driving the scraper 3 to rotate away from the roller brush 2. The area of ​​the part of the scraper 3 extending outside the first cavity 11 gradually decreases, eventually separating the scraper 3 from the surface to be cleaned and placing it in a suspended position. During this process, the drive component 4 synchronously drives the first connecting rod 51 to rotate around the fulcrum relative to the housing 1. The end of the first connecting rod 51 connected to the drive component 4 moves backward synchronously with the drive component 4, while the end of the first connecting rod 51 connected to the second connecting rod 52 swings in the opposite direction, causing the second connecting rod 52 to descend, so that the nozzle 6 moves to the second position, at which time the outlet 61 of the nozzle 6 faces the surface to be cleaned. When the scraper 3 is in the suspended position, the control module controls the solenoid valve to open, opening the cleaning liquid delivery channel, so that the cleaning liquid is sprayed onto the surface to be cleaned through the outlet 61 of the nozzle 6, achieving pre-wetting treatment of the surface to be cleaned.

[0075] It should be noted that the control module can control the opening and closing of the solenoid valve according to the signal of the sensing wheel 9. When the sensing wheel 9 detects the backward signal, the scraper 3 gradually rotates towards the roller brush 2. Assuming that the experimental data shows that the total time taken for the scraper 3 to rotate to the working position that is in close contact with the surface to be cleaned is 0.5 seconds, then the program can be set so that the control valve opens the cleaning liquid delivery channel at 0.6 seconds, so that the outlet 61 of the nozzle 6 starts to spray cleaning liquid.

[0076] In this embodiment, the control valve 8 controls the opening and closing of the cleaning fluid delivery channel, enabling on-demand supply of cleaning fluid and improving the targeting of cleaning. For example, the control valve 8 can open the cleaning fluid delivery channel only when the nozzle 6 is in the effective spraying position, i.e., the first position or the second position, and keep the cleaning fluid delivery channel closed in other operating conditions, thereby avoiding waste of cleaning fluid and controlling usage costs.

[0077] Optionally, in some embodiments of this application, reference is made to Figure 7 and Figure 8 The nozzle 6 has a fan-shaped or strip-shaped outlet 61. The cleaning liquid sprayed from the fan-shaped or strip-shaped outlet 61 is distributed in a planar or strip-shaped manner, which helps to expand the spray area and reduce pressure loss during the spraying process. Compared with point spraying, the fan-shaped or strip-shaped outlet 61 can achieve wide coverage without the need for the nozzle 6 to swing, thereby reducing the number of sprays and the amount of cleaning liquid consumed, reducing blind spots caused by uneven spraying, and improving the descaling efficiency of the scraping part 3 and the pre-wetting efficiency of the surface to be cleaned.

[0078] In summary, the floor brush assembly 100 provided in this application embodiment has multiple functions such as dirt scraping, roller brush cleaning, and cleaning fluid cleaning. The housing 1 adopts a cavity design, including a first cavity 11 and a second cavity 12. The first cavity 11 is used to carry components such as the drive component 4, the dirt scraping component 3, and the linkage mechanism 5. Each component forms a compact functional module through linkage. The second cavity 12 is parallel to the first cavity 11 along the length direction. A liquid storage tank 7 for storing cleaning fluid is embedded inside the second cavity 12. The drive component 4, as the core power output component, adopts a hollow cavity structure, serving the dual functions of power transmission and cleaning fluid transfer. The drive component 4 can reciprocate along its length and drive the scraper 32 to move via the transmission plate 31, positioning the scraper 32 in a working position against the surface to be cleaned or in a suspended position separated from the surface to be cleaned. Simultaneously, the drive component 4 is connected to a first connecting rod 51 and a second connecting rod 52 on opposite sides. The first connecting rod 51 and the second connecting rod 52 move in conjunction with the drive component 4, and the second connecting rod 52 drives the nozzle 6 to move, positioning the nozzle 6 in a first position or a second position, respectively spraying cleaning fluid onto the surface of the scraper 3 or the surface to be cleaned. Thus, the floor brush assembly 100 of this application can not only clean the dirt on the surface of the scraper 3, but also pre-wet the surface to be cleaned, enriching the functionality of the floor brush assembly 100.

[0079] Reference Figure 9 This application also provides a floor scrubber, including the floor brush assembly 100 described in any of the foregoing embodiments. The floor scrubber further includes a handle 200, which is rotatably connected to the housing 1 of the floor brush assembly 100. The handle 200 is designed to facilitate user operation and control the overall movement direction of the floor brush assembly 100.

[0080] The floor scrubber of this embodiment, due to the inclusion of the floor brush assembly 100 described above, also possesses the same technical effects as the floor brush assembly 100: Through the spray assembly, the floor brush assembly 100 can spray cleaning fluid onto the scraper 3 when it is in the working position. The cleaning fluid quickly soaks into the dirt adhering to the surface of the scraper 3, reducing the adhesion of the dirt. This allows the dirt to be carried away with the cleaning fluid during the cleaning process, preventing dirt accumulation on the scraper 3 and thus maintaining its cleanliness. This ensures better adhesion between the scraper 3 and the surface to be cleaned, improves the scraping effect, and avoids secondary contamination of the floor during subsequent cleaning. Furthermore, the spray assembly is linked to the drive assembly 4. As the drive assembly 4 moves the scraper 3, the spray assembly moves synchronously, achieving real-time linkage between the spraying and scraping actions. This helps to shorten the response delay between the two actions and ensures the continuity of the cleaning operation.
