Description

Technical Field

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

[0002] Cleaning equipment, such as floor scrubbers, is a type of cleaning machinery suitable for cleaning surfaces like floors and carpets. It simultaneously absorbs and removes wastewater from the site, offering advantages such as environmental friendliness, energy efficiency, and high performance. The scraper, as a key component of the cleaning equipment, works closely with the roller brush, using physical compression and scraping to evenly distribute water onto the brush, reducing the water stains left on the surface from forming watermarks after drying.

[0003] In related technologies, scrapers are mostly plate-shaped structures. Scrapers are not very effective at cleaning dirt such as hair tangled on the roller brush, and the surface to be cleaned tends to become dirtier the more it is cleaned. If the scraper is made into a toothed structure, the water distribution effect of the roller brush is poor, and watermarks are easily left on the surface to be cleaned. Utility Model Content

[0004] This application provides a floor brush assembly, cleaning equipment, and cleaning system that can solve the problem of difficult-to-clean dirt such as hair entangled on the roller brush, which affects the cleaning effect, while ensuring the uniform water distribution on the roller brush.

[0005] In a first aspect, this application provides a floor brush component, which includes:

[0006] The floor brush body is equipped with a suction port;

[0007] A roller brush, located at the front end of the floor brush body along the forward direction of the floor brush body, with the suction port facing the roller brush;

[0008] A water distributor is disposed on the main body of the floor brush, the water distributor is located above the suction port, and the spray nozzle of the water distributor faces the roller brush;

[0009] A scraper assembly, at least a portion of which is located above the suction port, the scraper assembly including a scraper blade and a comb-tooth scraper, the scraper blade being rotatably connected to the floor brush body and capable of flipping towards the roller brush; the comb-tooth scraper being rotatably connected to the floor brush body and capable of flipping towards the roller brush.

[0010] A force-applying component is connected to the scraper assembly. The force-applying component is used to drive at least one of the scraper and the comb-tooth scraper to rotate in the direction of the roller brush, so that both the scraper and the comb-tooth scraper abut against the roller brush.

[0011] The floor brush assembly provided in this application allows the distributor to spray liquid onto the surface of the roller brush to wet it as the roller brush rotates past it. The distributor has multiple spaced-apart nozzles for spraying liquid onto the roller brush surface. Therefore, it is easy to understand that the area of ​​the roller brush directly opposite the nozzles has a higher liquid content than other areas. Consequently, when the roller brush moves across the surface to be cleaned, areas with higher liquid content will leave more watermarks on the surface.

[0012] The scraper assembly fits tightly against the roller brush. The scraper exerts a uniform force on the roller brush bristles, allowing liquid in areas with high liquid content to spread outwards. This improves the evenness of liquid distribution on the roller brush and reduces the likelihood of watermarks forming after drying on the surface being cleaned.

[0013] In particular, as the roller brush wears down over time, its diameter decreases, reducing the contact depth between the scraper and the roller brush. This can even lead to gaps between them, weakening or eliminating the scraper's ability to evenly distribute water, resulting in more noticeable watermarks on the surface to be cleaned. Therefore, by rotating the scraper, it's possible to maintain contact with the roller brush, ensuring an effective contact depth and allowing for continued good water distribution even as the roller brush wears down.

[0014] Because the scraper exerts a force towards the roller brush, it also has a squeezing effect on the roller brush. This squeezing action reduces the water content within the roller brush, improving drying efficiency and minimizing the likelihood of water stains forming on the surface. Furthermore, when the roller brush generates dirt while cleaning, the scraper can squeeze out the wastewater, which can then enter the wastewater tank through the suction port. Therefore, the scraper provides a certain degree of cleaning effect on the roller brush.

[0015] In this embodiment, the force-applying component can be used to rotate the scraper towards the roller brush, so that the scraper and the roller brush remain in contact. The force-applying component can provide a force to the scraper towards the roller brush. Therefore, when the roller brush wears down after long-term use, the force-applying component can maintain the water-spreading and squeezing force between the scraper and the roller brush, thereby reducing the possibility that the water-spreading and squeezing force of the scraper on the roller brush will decrease and affect the cleaning effect on the surface to be cleaned.

[0016] In this embodiment, the scraper assembly can be inserted deep into the bristles of the roller brush to remove dirt such as hair and debris from the bristles, thereby reducing the possibility of secondary contamination of the surface to be cleaned.

[0017] In this embodiment, the force-applying component can be used to rotate the comb-tooth scraper towards the roller brush, so that the comb-tooth scraper and the roller brush remain in contact. The force-applying component can provide a force to the comb-tooth scraper towards the roller brush, so that even after the roller brush has been worn down by long-term use, the force-applying component can maintain the interaction force between the comb-tooth scraper and the roller brush, and there is an effective contact depth between the comb-tooth scraper and the roller brush, so as to improve the stability and reliability of removing dirt such as hair from the roller brush and ensure the cleaning effect.

[0018] It should be noted that after the comb-tooth scraper inserts deep into the bristles of the roller brush to remove hair and other dirt, the bristles may be uneven in shape and not fully flattened. For example, the fluffiness of the bristles near and away from the comb-tooth scraper may differ. When the distributor sprays liquid onto the roller brush again, this can easily lead to uneven water distribution on the bristles. Therefore, as the roller brush rotates, after the comb-tooth scraper cleans the dirt deep within the bristles, the scraper can smooth out the uneven bristles, making their shape more uniform. This ensures more even water distribution during subsequent cleaning and improves the cleaning effect.

[0019] Furthermore, it should be noted that in this embodiment, the scraper, under the action of the force-applying component, has a flipping motion towards the roller brush. Therefore, it is easy to understand that a small stroke of the scraper's flipping motion can achieve a large abutting force on the roller brush, which helps to save the large internal space occupied by the scraper's movement in the main body of the floor brush. Moreover, the small stroke of the scraper's flipping motion helps to improve the reliability of the scraper's flipping motion and reduce the failure rate.

[0020] Similarly, under the action of the force-applying component, the comb blades have a flipping motion towards the roller brush. Therefore, the comb blades' relatively short stroke can achieve a large resisting force on the roller brush, which helps to save the large internal space occupied by the comb blades in the brush body. Furthermore, the short stroke of the comb blades improves the reliability of their flipping motion and reduces the failure rate.

[0021] In addition, the tumbling motion of the scraper and the comb blades can ensure the force exerted by the scraper and the comb blades on the roller brush while minimizing the relative movement path between the scraper and the comb blades. This reduces the impact of the relative movement between the scraper and the comb blades on the seal between them, and helps to reduce the possibility of dirt entering the brush body through the gap between the scraper and the comb blades.

[0022] According to one embodiment of this application, the tumbling motion of the scraper towards the roller brush is independent of the tumbling motion of the comb-tooth scraper towards the roller brush, and relative motion can occur between the scraper and the comb-tooth scraper.

[0023] In this embodiment, the flipping motion of the scraper and the flipping motion of the comb-tooth scraper can be independent of each other, so that the flipping motion of one is not easily affected by the flipping motion of the other, thereby reducing the possibility that a failure of one will affect the reliability of the motion of the other, which is beneficial to ensuring the stable motion of the scraper and the comb-tooth scraper.

[0024] Because the scraper's contact force against the roller brush can squeeze out the wastewater inside the roller brush, the scraper can have a certain cleaning effect on the roller brush. By setting the scraper and the comb-tooth scraper's rotational movements to be independent of each other, when the comb-tooth scraper fails, the scraper can squeeze out the wastewater and other dirt inside the roller brush while providing a uniform water distribution, thus achieving a cleaning effect on the roller brush.

[0025] According to one embodiment of this application, the force-applying component includes a first elastic element along the forward direction of the floor brush body. One end of the first elastic element is connected to the comb-tooth scraper, and the other end of the first elastic element is connected to the floor brush body. The first elastic element is used to drive the comb-tooth scraper to maintain contact with the roller brush.

[0026] In this embodiment, the first elastic element can be used to provide a force for the comb bar to rotate toward the roller brush, so that after long-term use of the roller brush, the comb bar and the roller brush can maintain a relative force and have an effective contact depth, thereby ensuring the cleaning effect of the comb bar on hair and other dirt on the roller brush.

[0027] The first elastic element provides a constant pushing force against the brush roller on the comb-tooth scraper. The first elastic element has a simple structure, good reliability, and is easy to install and maintain.

[0028] The force-applying component includes a second elastic element. Along the forward direction of the floor brush body, one end of the second elastic element is connected to the scraper, and the other end of the second elastic element is connected to the floor brush body. The second elastic element is used to drive the scraper to maintain contact with the roller brush.

[0029] In this embodiment, the second elastic element can be used to provide a force for the scraper to rotate toward the roller brush, so that after long-term use of the roller brush, the scraper and the roller brush can maintain a relative force and have an effective contact depth, thereby ensuring the scraper's effect on the roller brush in terms of water distribution and squeezing.

[0030] Therefore, the first and second elastic elements can independently drive the comb blades and scraper to maintain contact with the roller brush, so that if one fails, the other can continue to operate normally. Users or staff can perform maintenance on the malfunctioning element individually.

[0031] According to one embodiment of this application, the comb-tooth scraper and the scraper are arranged side by side along the height direction of the floor brush body, and the scraper is located between the water distributor and the comb-tooth scraper.

[0032] In this embodiment, by arranging the comb-tooth scraper and the scraper side by side along the height direction of the brush body, the comb-tooth scraper and the scraper can clean and distribute water evenly on the brush in sequence during the rotation of the brush.

[0033] Specifically, during the forward movement of the brush body, a scraper is positioned between the water distributor and the comb-tooth scraper. The process of the roller brush cleaning the surface to be cleaned is as follows: the water distributor sprays liquid onto the roller brush to wet it. The wet roller brush can clean the surface to be cleaned and absorb dirt from it. Then, hair and other dirt deep within the brush bristles are detached from the roller brush by the action of the comb-tooth scraper. The dirt falls downwards under its own weight and is sucked into the wastewater tank through the suction port under negative pressure. Since the brush bristles are flattened to varying degrees by the action of the comb-tooth scraper, the scraper can smooth the bristles to facilitate re-wetting of the roller brush. Because the toothed structure on the comb-tooth scraper is not very effective at evenly distributing and squeezing water from the roller brush, the scraper can squeeze the wastewater on the roller brush to expel it, thereby improving the cleaning effect of the roller brush. When the roller brush passes through the distributor again to spray liquid, the clean roller brush can continue to clean the surface to be cleaned, thereby improving the cleaning effect.

[0034] According to one embodiment of this application, the scraper is disposed on the surface of the water distributor facing the comb-tooth scraper.

[0035] In this embodiment, the scraper and the water distributor can rotate synchronously. Under the action of the second elastic member, an effective contact depth can be maintained between the scraper and the roller brush, and an effective spraying distance can be maintained between the water distributor and the roller brush. The scraper can penetrate part of the roller brush bristles. There is a gap between the water distributor's spray nozzle and the roller brush, allowing the spray nozzle to spray radially towards the roller brush, thereby increasing the spraying area.

[0036] According to one embodiment of this application, the scraper protrudes from the side of the water distributor facing the roller brush.

[0037] In this embodiment, by setting the scraper to protrude from the surface of the distributor facing the roller brush, the scraper can be inserted into the bristles of the roller brush, maintaining contact with the roller brush, and the distributor can guide the liquid onto the roller brush. In other words, the scraper and the roller brush bristles can maintain an effective contact depth, while the distributor and the roller brush can have an effective spraying distance.

[0038] According to one embodiment of this application, along the height direction of the floor brush body, there is a first gap between the scraper and the comb-tooth scraper, and a first sealing member is provided at the first gap, the first sealing member being used to prevent dirt from entering the floor brush body.

[0039] In this embodiment, the first gap provides space for the tumbling motion of the scraper and the comb-tooth scraper, reducing the possibility of jamming during the tumbling of the scraper and the comb-tooth scraper. By providing a first seal at the first gap, the possibility of dirt carried up by the rotating roller brush and dirt scraped off by the scraper from the roller brush entering the interior of the floor brush body through the first gap can be reduced.

[0040] It's easy to understand that since both the scraper and the comb-tooth scraper move in a rotating motion, their movement paths are relatively small, and the dimension of the first gap along the height direction of the brush body can also be set relatively small. Correspondingly, the dimension of the first seal along the height direction of the brush body can also be set relatively small, which helps to save on the material cost of the first seal.

[0041] According to one embodiment of this application, there is a second gap between the comb-tooth scraper and the floor brush body, and a second seal is provided at the second gap, the second seal being used to prevent dirt from entering the floor brush body.

[0042] In this embodiment, since both the scraper and the comb-tooth scraper have a flipping motion, the primary sealing part and the secondary sealing part have different degrees of compression between the scraper and the comb-tooth scraper. By providing the primary and secondary sealing parts, a double seal for the first gap can be achieved. If one of the primary and secondary sealing parts fails, the other can still perform the sealing function.

[0043] According to one embodiment of this application, the comb-tooth scraper includes a comb tooth portion and a rear end limiting portion. The comb tooth portion is used to contact the roller brush. Along the forward direction of the floor brush body, the scraper is located on the side of the rear end limiting portion facing the roller brush.

[0044] In this embodiment, the rear limiting part can limit the scraper, thereby reducing the possibility of the scraper moving away from the roller brush during the flipping of the comb bar and the scraper.

[0045] Furthermore, when the second elastic element fails, preventing the scraper from flipping towards the roller brush, the first elastic element applies a force towards the roller brush to the comb-tooth scraper, causing the rear end limiting part of the comb-tooth scraper to abut against the scraper. This rear end limiting part then pushes the scraper towards the roller brush, ensuring the scraper and roller brush remain in contact. At this point, the scraper and roller brush have an effective contact depth for evenly distributing and squeezing water from the roller brush.

[0046] According to one embodiment of this application, the scraper is inclined relative to the surface to be cleaned, and the scraper gradually increases in height along the forward direction of the brush body.

[0047] In this embodiment, the scraper can be gradually tilted upwards from front to back along the forward direction of the brush body, so that the liquid thrown out by the rotating roller brush and the liquid squeezed by the scraper are less likely to flow upwards along the side wall of the scraper into the interior of the brush body.

[0048] According to one embodiment of this application, the comb-tooth scraper is inclined relative to the surface to be cleaned, and the comb-tooth scraper gradually increases in height along the forward direction of the floor brush body.

[0049] In this embodiment, the comb-tooth scraper can gradually tilt upwards along the forward direction of the brush body from front to back, so that the liquid thrown out by the rotating roller brush and the liquid squeezed by the scraper from the roller brush are less likely to flow upwards along the side wall of the comb-tooth scraper into the interior of the brush body.

[0050] According to one embodiment of this application, the scraper is located above the horizontal plane containing the center line of the roller brush.

[0051] In this embodiment, the scraper is located above the horizontal plane containing the center line of the roller brush, and the contact point between the scraper and the roller brush is also located above the horizontal plane containing the center line of the roller brush. When the roller brush rotates counterclockwise, the roller brush can exert a force on the scraper in the direction of the roller brush, so that the scraper and the roller brush can remain in contact as the roller brush wear diameter decreases.

[0052] In some examples, the extension line of the scraper can pass through the center of the roller brush. Alternatively, the extension line of the scraper can be located below the horizontal plane where the center of the roller brush is located.

[0053] When the extension line of the scraper is above the horizontal plane where the center of the roller brush is located, the counterclockwise rotation of the roller brush and the action of the second elastic element result in excessive contact force between the scraper and the roller brush. This leads to a slow relative speed between the scraper and the roller brush, and direct contact between the scraper and the root of the roller brush. Therefore, when the scraper squeezes water from the root of the roller brush bristles, the squeezing effect on areas far from the root is weak, easily leading to uneven water squeezing and affecting the overall squeezing effect. Furthermore, excessive contact force between the scraper and the roller brush increases the rotational resistance of the roller brush, potentially increasing the current of the drive motor that drives the roller brush.

[0054] By setting the extension line of the scraper to pass through the center of the roller brush, or by placing the extension line of the scraper below the horizontal plane where the center of the roller brush is located, the scraper can first contact the middle part of the roller brush bristles. Then, under the counterclockwise rotation of the roller brush and the action of the second elastic element, the scraper can gradually and quickly flatten the roller brush bristles and squeeze water from the entire bristle. This can improve the uniformity and fullness of water squeezing on the roller brush and improve the water squeezing effect.

[0055] Secondly, this application provides a floor brush component, which includes:

[0056] The floor brush body is equipped with a suction port;

[0057] A roller brush, located at the front end of the floor brush body along the forward direction of the floor brush body, with the suction port facing the roller brush;

[0058] A water distributor is disposed on the main body of the floor brush, the water distributor is located above the suction port, and the spray nozzle of the water distributor faces the roller brush;

[0059] A scraper assembly, at least a portion of which is located above the suction port, the scraper assembly including a comb-tooth scraper and a scraper blade, the comb-tooth scraper being slidably connected to the floor brush body, and the scraper blade being movably connected to the floor brush body;

[0060] A force-applying component is connected to the scraper assembly. The force-applying component is used to drive the comb-tooth scraper and the scraper to move in the direction of the roller brush, so that the scraper and the comb-tooth scraper both abut against the roller brush.

[0061] In this embodiment, the toothed scraper can slide towards the roller brush under the action of the force-applying component, so that the toothed scraper and the roller brush remain in contact. Therefore, after the roller brush wears down from long-term use, the force-applying component can maintain the interaction force between the toothed scraper and the roller brush, and there is an effective contact depth between the toothed scraper and the roller brush, so as to improve the stability and reliability of removing dirt such as hair from the roller brush and ensure the cleaning effect.

[0062] Specifically, by applying a force to the comb blade in the direction of the roller brush through the force-applying component, an effective contact depth can always be maintained between the comb blade and the roller brush. In particular, when the roller brush wears down and its size decreases, the comb blade can move in the direction of the roller brush to maintain the effective contact depth between the comb blade and the roller brush.

[0063] It should be noted that in this embodiment, the comb-tooth scraper is slidably connected to the brush body, and the movement trajectory of the comb-tooth scraper is linear. As the roller brush wears down over time, its diameter will decrease. By setting the comb-tooth scraper to slide relative to the brush body, the angle of the comb-tooth scraper relative to the roller brush can remain constant while the comb-tooth scraper and roller brush are in contact, thereby ensuring the stability and reliability of the comb-tooth scraper in removing hair and other dirt from the roller brush.

[0064] According to one embodiment of this application, the comb-tooth scraper includes a comb tooth portion and a rear end limiting portion. The comb tooth portion is used to contact the roller brush. Along the forward direction of the floor brush body, the end of the scraper away from the roller brush abuts against the rear end limiting portion.

[0065] In this embodiment, the rear limiting part can limit the scraper, so as to prevent the scraper from moving away from the roller brush during the sliding of the comb tooth scraper and the movement of the scraper.

[0066] Furthermore, after long-term use and wear, when the scraper can no longer move in the direction of the roller brush, the comb-tooth scraper can slide in the direction of the roller brush, so that the rear end limiting part of the comb-tooth scraper can abut against the scraper. Thus, the rear end limiting part pushes the scraper to move in the direction of the roller brush, and the scraper and roller brush can maintain abutment.

[0067] According to one embodiment of this application, the force-applying component includes a first elastic element, one end of which is connected to the comb-tooth scraper and the other end of which is connected to the floor brush body. The first elastic element is used to drive the comb-tooth scraper to maintain contact with the roller brush and to keep the scraper in contact with the roller brush.

[0068] In this embodiment, the first elastic element can be used to provide a force for the comb bar to slide toward the roller brush, so that after the roller brush is worn down by long-term use, the comb bar and the roller brush can maintain a relative force, thereby ensuring the cleaning effect of the comb bar on hair and other dirt on the roller brush.

[0069] The first elastic element provides a constant pushing force against the brush roller on the comb-tooth scraper. The first elastic element has a simple structure, good reliability, and is easy to install and maintain.

[0070] According to one embodiment of this application, the floor brush body is provided with a sliding groove for the scraper to slide, so that when the comb-tooth scraper rotates toward the roller brush, the scraper slides along the sliding groove toward the roller brush, and the comb-tooth scraper abuts against the roller brush.

[0071] In this embodiment, the groove can guide the sliding of the comb bar, so that the comb bar can slide stably in the direction of the roller brush, which helps to maintain the tilt angle of the comb bar relative to the roller brush, thereby ensuring the removal effect of hair and other dirt on the roller brush.

[0072] According to one embodiment of this application, the scraper is rotatably connected to the floor brush body, and the scraper has a rolling motion toward the roller brush direction.

[0073] In this embodiment, the comb-tooth scraper can slide relative to the brush body, and the scraper can rotate relative to the brush body. Therefore, the sliding motion of the comb-tooth scraper and the rotating motion of the scraper can be independent of each other. The comb-tooth scraper and the scraper are less likely to interfere with each other. Furthermore, when one of them malfunctions, the other can continue to operate normally.

[0074] In particular, when the comb-tooth scraper malfunctions, it becomes difficult to effectively clean the roller brush. The scraper and roller brush can remain in contact, allowing the scraper to clean the roller brush.

[0075] Thirdly, this application provides a cleaning device comprising:

[0076] body;

[0077] In any of the above embodiments, the floor brush assembly is connected to the main body.

[0078] Fourthly, this application provides a cleaning system comprising:

[0079] Base station or base station;

[0080] And cleaning equipment, which can be placed on a base or base station.

[0081] The beneficial effects of the floor brush assembly provided in this application are that the scraper and the roller brush can maintain contact. In particular, when the roller brush wears down over a long period of use, causing its size to decrease, the scraper can still achieve an effective contact depth with the roller brush under the action of the force-applying component. The relative force between the scraper and the roller brush ensures that the scraper can still effectively distribute and squeeze water against the roller brush.

[0082] The water-distributing action ensures even liquid distribution on the roller brush, reducing the likelihood of excessive liquid in certain areas causing watermarks on the surface to be cleaned. The scraper's action of squeezing water from the roller brush reduces its internal water content, minimizing the possibility of water stains on the surface. Furthermore, when the roller brush becomes dirty while cleaning, the scraper can squeeze out the wastewater from within the brush.

[0083] The toothed scraper and the roller brush maintain contact. As the roller brush wears down over time, reducing its size, the force applied by the force-bearing components ensures an effective contact depth between the toothed scraper and the roller brush. Maintaining relative force between the toothed scraper and the roller brush improves the stability and reliability of removing hair and other dirt from the roller brush, guaranteeing a cleaning effect.

[0084] In addition, the scraper assembly includes a scraper and a comb-tooth scraper, and the scraper can squeeze out sewage. Therefore, when the comb-tooth scraper fails, the scraper can squeeze out sewage and other dirt in the roller brush while providing water evenly to the roller brush, thus achieving a cleaning effect on the roller brush.

[0085] In addition to the technical problems solved by the embodiments of the present invention, the technical features constituting the technical solutions, and the beneficial effects brought about by the technical features of these technical solutions described above, other technical problems that can be solved by the floor brush components, cleaning equipment, and cleaning systems provided by the embodiments of the present invention, other technical features included in the technical solutions, and the beneficial effects brought about by these technical features will be further explained in detail in the specific embodiments.

[0107] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. 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 particular embodiments. Detailed Implementation

[0108] 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 represent 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. Clearly, the described embodiments are only a portion, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0109] This application provides a cleaning device, which may be, but is not limited to, a floor scrubber. This application uses a floor scrubber as an example. A floor scrubber is a device used for cleaning floors and generally consists of multiple parts such as a brush assembly, a roller brush, a clean water tank, and a wastewater tank. The working principle of the floor scrubber is as follows: the high-speed rotation of the motor drives the roller brush to rotate at high speed, while the clean water tank rotates, spraying clean water forward onto the roller brush through a water path. In conjunction with the high-speed rotation of the roller brush, wastewater is drawn into the wastewater tank through a suction port located behind the roller brush and another water path, thus completing the cleaning process.

[0110] Roller brushes and scrapers are key components of cleaning equipment. The main function of the roller brush is to clean the surface to be cleaned through mechanical rotation and friction. The scraper, by closely adhering to the roller brush, uses physical squeezing and scraping to distribute water evenly over the roller brush, reducing watermarks that form on the surface after drying.

[0111] In related technologies, scrapers are mostly plate-shaped structures. Scrapers are not very effective at cleaning dirt such as hair tangled on the roller brush, and the surface to be cleaned tends to become dirtier the more it is cleaned. If the scraper is made into a toothed structure, the water distribution effect of the roller brush is poor, and watermarks are easily left on the surface to be cleaned.

[0112] Based on the aforementioned technical problems, the applicant has improved the structure of existing floor brush components. In this embodiment, the scraper assembly includes a scraper blade and a comb-tooth scraper. The scraper blade can fit closely to the roller brush to evenly distribute water on the roller brush, thereby reducing the possibility of watermarks forming after the water stains on the surface to be cleaned dry. The comb-tooth scraper can be inserted deep into the bristles of the roller brush to remove hair, debris, and other dirt from the bristles, thereby reducing the possibility of secondary contamination of the surface to be cleaned.

[0113] Therefore, in this embodiment, the scraper assembly can evenly distribute water onto the roller brush via the scraper blade, reducing the likelihood of watermarks on the surface to be cleaned. The comb-like scraper can be used to remove hair and other dirt deep within the roller brush. The scraper assembly effectively improves the cleaning effect on the surface to be cleaned, enhancing the user experience.

[0114] The floor brush assembly 100, cleaning equipment, and cleaning system provided in this application are described below with reference to the accompanying drawings and specific embodiments.

[0115] See Figures 1 to 4 As shown, the floor brush assembly 100 of this application embodiment includes a floor brush body 110, a roller brush 120, a water distributor 130, a scraper assembly 140, and a force-applying component 150.

[0116] The floor brush body 110 is provided with a suction port 110a. Along the forward direction X of the floor brush body 110, the roller brush 120 is located at the front end of the floor brush body 110. The suction port 110a faces the roller brush 120.

[0117] During operation, the roller brush 120 cleans the dirt on the surface to be cleaned. The dirt can then enter the wastewater tank of the cleaning equipment through the suction port 110a under negative pressure.

[0118] The water distributor 130 is disposed on the main body 110 of the floor brush. The water distributor 130 is located above the suction port 110a, and the spray nozzle of the water distributor 130 faces the roller brush 120. The water distributor 130 can be used to supply liquid to the roller brush 120 to wet the roller brush 120, so that the wet roller brush 120 can perform wet cleaning on the surface to be cleaned, which is beneficial to improving the cleaning effect on stubborn stains on the surface to be cleaned.

[0119] At least a portion of the scraper assembly 140 is located above the suction port 110a. The scraper assembly 140 includes a scraper blade 141 and a comb-tooth scraper blade 142. The scraper blade 141 is rotatably connected to the brush body 110. The scraper blade 141 can be flipped toward the roller brush 120. The comb-tooth scraper blade 142 is rotatably connected to the brush body 110. The comb-tooth scraper blade 142 can be flipped toward the roller brush 120.

[0120] The force-applying element 150 is connected to the scraper assembly 140. The force-applying element 150 is used to drive at least one of the scraper 141 and the comb-tooth scraper 142 to rotate in the direction of the roller brush 120, so that both the scraper 141 and the comb-tooth scraper 142 abut against the roller brush 120.

[0121] As the roller brush 120 rotates past the water distributor 130, the water distributor 130 sprays liquid onto the surface of the roller brush 120 to wet it. The water distributor 130 has multiple spaced-apart nozzles for spraying liquid onto the surface of the roller brush 120. Therefore, it is easy to understand that the area of ​​the roller brush 120 directly opposite the nozzles has a higher liquid content than other areas. Consequently, when the roller brush 120 moves across the surface to be cleaned, the areas with higher liquid content will leave more watermarks on the surface.

[0122] In this embodiment, the scraper 141 of the scraper assembly 140 is in close contact with the roller brush 120. The scraper 141 can exert a water-distributing force on the bristles of the roller brush 120, so that the liquid in areas with high liquid content on the roller brush 120 can be diffused to the surroundings, thereby improving the uniformity of liquid distribution on the roller brush 120 and reducing the possibility that water stains generated by the roller brush 120 on the surface to be cleaned will form watermarks after drying.

[0123] In particular, as the roller brush 120 wears down over time, its diameter decreases, reducing the contact depth between the scraper 141 and the roller brush 120, and even creating a gap between them. In this case, the scraper 141's water-distributing effect on the roller brush 120 weakens or even fails, resulting in more noticeable watermarks on the surface to be cleaned. Therefore, by rotating the scraper 141, it can maintain contact with the roller brush 120, ensuring an effective contact depth so that even when the roller brush 120 is worn, it can still provide a good water-distributing effect.

[0124] Because the scraper 141 exerts a force towards the roller brush 120, it also has a water-squeezing effect on the roller brush 120. Through this water-squeezing action, the scraper 141 reduces the water content within the roller brush 120, improving the drying efficiency of the surface to be cleaned and reducing the likelihood of water stains forming on the surface. Furthermore, when the roller brush 120 becomes dirty while cleaning the surface, the scraper 141 can squeeze out the wastewater, which can then enter the wastewater tank through the suction port 110a. Therefore, the scraper 141 provides a certain degree of cleaning effect on the roller brush 120.

[0125] In this embodiment, the force-applying member 150 can be used to rotate the scraper 141 toward the roller brush 120, so that the scraper 141 and the roller brush 120 remain in contact. The force-applying member 150 can provide a force to the scraper 141 toward the roller brush 120. Therefore, when the roller brush 120 wears out after long-term use, the force-applying member 150 can maintain the water-spreading and squeezing force between the scraper 141 and the roller brush 120, thereby reducing the possibility that the water-spreading and squeezing force of the scraper 141 on the roller brush 120 will decrease and affect the cleaning effect on the surface to be cleaned.

[0126] In this embodiment, the scraper assembly 140 can be inserted into the depth of the bristles of the roller brush 120 via the comb-tooth scraper 142 to remove hair, debris and other dirt from the depth of the bristles of the roller brush 120, thereby reducing the possibility of secondary contamination of the surface to be cleaned by dirt.

[0127] In this embodiment, the force-applying member 150 can be used to rotate the comb-tooth scraper 142 toward the roller brush 120, so that the comb-tooth scraper 142 and the roller brush 120 remain in contact. The force-applying member 150 can provide a force to the comb-tooth scraper 142 toward the roller brush 120, so that even after the roller brush 120 has been worn down by long-term use, the force-applying member 150 can maintain the interaction force between the comb-tooth scraper 142 and the roller brush 120, and there is an effective contact depth between the comb-tooth scraper 142 and the roller brush 120, so as to improve the stability and reliability of removing dirt such as hair from the roller brush 120 and ensure the cleaning effect.

[0128] It should be noted that after the comb-tooth scraper 142 is inserted deep into the bristles of the roller brush 120 to remove hair and other dirt, the bristles of the roller brush 120 may be uneven in degree of flattening. For example, the fluffiness of the bristles near the comb-tooth scraper 142 differs from that away from it. When the water distributor 130 sprays liquid onto the roller brush 120 again, it can easily lead to uneven water absorption by the bristles and uneven liquid distribution. Therefore, as the roller brush 120 rotates, after the comb-tooth scraper 142 cleans the dirt deep within the bristles, the scraper 141 can smooth out the unevenly flattened bristles, making the bristles of the roller brush 120 more uniform in state. This facilitates more even water absorption by the roller brush 120 and improves the cleaning effect.

[0129] Furthermore, it should be noted that in this embodiment, the scraper 141, under the action of the force-applying member 150, has a flipping motion towards the roller brush 120. Therefore, it is easy to understand that a small flipping stroke of the scraper 141 can achieve a large abutting force on the roller brush 120, which helps to save a large amount of internal space occupied by the scraper 141 in the brush body 110. Moreover, the small flipping stroke of the scraper 141 helps to improve the reliability of the scraper 141's flipping motion and reduce the failure rate.

[0130] Similarly, under the action of the force-applying component 150, the comb blade 142 rotates towards the roller brush 120. Therefore, the comb blade 142's relatively small stroke can achieve a large abutting force on the roller brush 120, which helps to save the large internal space occupied by the comb blade 142 in the brush body 110. Furthermore, the small stroke of the comb blade 142 helps to improve the reliability of its rotational movement and reduce the failure rate.

[0131] Furthermore, the flipping motion of the scraper 141 and the comb-tooth scraper 142 ensures that the scraper 141 and the comb-tooth scraper 142 exert force on the roller brush 120 while minimizing the relative movement path between them. This reduces the impact of the relative movement between the scraper 141 and the comb-tooth scraper 142 on the seal between them, and helps to reduce the possibility of dirt entering the brush body 110 through the gap between the scraper 141 and the comb-tooth scraper 142.

[0132] In some examples, the force-applying element 150 can be used to provide power for the flipping action of the scraper 141 and the comb-tooth scraper 142, so that both the scraper 141 and the comb-tooth scraper 142 can maintain contact with the roller brush 120. The scraper 141 and the comb-tooth scraper 142 can flip synchronously, or the scraper 141 and the comb-tooth scraper 142 can flip independently, which is not limited in this embodiment.

[0133] In some examples, the portion of scraper 141 that contacts roller brush 120 may have a plate-like structure. Scraper 141 makes full contact with roller brush 120.

[0134] For example, the portion of the scraper 141 that contacts the roller brush 120 can be a flat, plate-like structure. For instance, the scraper 141 can extend along the axial direction Z of the roller brush 120.

[0135] In some examples, the portion of the comb bar 142 that contacts the roller brush 120 may be toothed. The tips of the teeth may penetrate deep into the roots of the bristles of the roller brush 120 to remove dirt from deep within the bristles.

[0136] In some examples, the comb-tooth scraper 142 may include multiple teeth. The multiple teeth may be evenly distributed at Z-intervals along the axial direction of the roller brush 120.

[0137] See also some of the possible implementation methods. Figure 5 and Figure 6 As shown, in this embodiment of the application, the flipping motion of the scraper 141 toward the roller brush 120 is independent of the flipping motion of the comb-tooth scraper 142 toward the roller brush 120. Relative motion can occur between the scraper 141 and the comb-tooth scraper 142.

[0138] In this embodiment, the flipping motion of the scraper 141 and the flipping motion of the comb tooth scraper 142 can be independent of each other, so that the flipping motion of one is not easily affected by the flipping motion of the other, thereby reducing the possibility that a failure of one will affect the reliability of the motion of the other, which is beneficial to ensuring the stable motion of the scraper 141 and the comb tooth scraper 142.

[0139] Because the scraper 141's contact force against the roller brush 120 can squeeze out the sewage inside the roller brush 120, the scraper 141 can have a certain cleaning effect on the roller brush 120. By setting the rotational movements of the scraper 141 and the comb-tooth scraper 142 to be independent of each other, when the comb-tooth scraper 142 fails, the scraper 141 can squeeze out the sewage and other dirt inside the roller brush 120 while providing a uniform water distribution, thus achieving a cleaning effect on the roller brush 120.

[0140] In some examples, the scraper 141 and the comb-tooth scraper 142 can be flipped around the same axis, or the scraper 141 and the comb-tooth scraper 142 can be flipped around different axes, which is not limited in the embodiments of this application.

[0141] For example, see Figure 5 and Figure 6 As shown, both the scraper 141 and the toothed scraper 142 can be rotated around the pivot 143. The pivot 143 can be mounted on the brush body 110. The toothed scraper 142 can be connected to the pivot 143 via a bracket 144.

[0142] In some examples, the support 144 may include a support plate 1441 and a cantilever 1442. The support plate 1441 may extend along the axial direction Z of the roller brush 120 and connect to the comb blade 142 to improve the structural strength of the comb blade 142 and reduce the possibility of deformation of the comb blade 142. The cantilever 1442 may be located at both ends of the support plate 1441. The cantilever 1442 may be used to connect to the rotating shaft 143.

[0143] In some examples, the support 144 may be formed of, but is not limited to, a metallic material.

[0144] See also some of the possible implementation methods. Figures 4 to 6 As shown, the force-applying component 150 in this embodiment includes a first elastic component 151. Along the forward direction X of the brush body 110, one end of the first elastic component 151 is connected to the comb-tooth scraper 142. The other end of the first elastic component 151 is connected to the brush body 110. The first elastic component 151 is used to drive the comb-tooth scraper 142 to maintain contact with the roller brush 120.

[0145] In this embodiment, the first elastic member 151 can be used to provide a force for the comb bar 142 to rotate toward the roller brush 120, so that after long-term use of the roller brush 120, the comb bar 142 and the roller brush 120 can maintain a relative force and have an effective contact depth, thereby ensuring the cleaning effect of the comb bar 142 on hair and other dirt on the roller brush 120.

[0146] The first elastic element 151 can always exert an elastic force on the comb-tooth scraper 142, pushing it towards the roller brush 120. The first elastic element 151 has a simple structure, good reliability, and is easy to install and maintain.

[0147] In some examples, the side of the comb-tooth scraper 142 facing away from the roller brush 120 may be provided with a fixing post for fixing the first elastic member 151. One end of the first elastic member 151 may be sleeved on the fixing post.

[0148] See also some of the possible implementation methods. Figures 4 to 6 As shown, the force-applying component 150 includes a second elastic element 152. Along the forward direction X of the floor brush body 110, one end of the second elastic element 152 is connected to the scraper 141. The other end of the second elastic element 152 is connected to the floor brush body 110. The second elastic element 152 is used to drive the scraper 141 to maintain contact with the roller brush 120.

[0149] In this embodiment, the second elastic element 152 can be used to provide a force for the scraper 141 to rotate toward the roller brush 120, so that after long-term use of the roller brush 120, the scraper 141 and the roller brush 120 can maintain a relative force and have an effective contact depth, thereby ensuring the water distribution and squeezing effect of the scraper 141 on the roller brush 120.

[0150] Therefore, the first elastic element 151 and the second elastic element 152 can independently drive the comb-tooth scraper 142 and the scraper 141 to maintain contact with the roller brush 120, so that if one of them fails, the other can operate normally. The user or staff can perform maintenance on the one that fails individually.

[0151] In some examples, the scraper 141 may have a fixing post on the side facing away from the roller brush 120 for fixing the second elastic member 152. One end of the second elastic member 152 may be sleeved on the fixing post.

[0152] In some examples, the first elastic element 151 and the second elastic element 152 may be, but are not limited to, springs.

[0153] See also some of the possible implementation methods. Figure 2As shown, in this embodiment of the application, the comb-tooth scraper 142 and the scraper 141 are arranged side by side along the height direction Y of the floor brush body 110. The scraper 141 is located between the water distributor 130 and the comb-tooth scraper 142.

[0154] In this embodiment, the comb-tooth scraper 142 and the scraper 141 are arranged side by side along the height direction Y of the brush body 110, so that the comb-tooth scraper 142 and the scraper 141 can clean and water evenly on the brush 120 in sequence during the rotation of the brush 120.

[0155] Specifically, refer to Figure 2 As shown, the roller brush 120 can rotate counterclockwise during the forward movement of the brush body 110. A scraper 141 is positioned between the water distributor 130 and the comb-tooth scraper 142. The process of the roller brush 120 cleaning the surface to be cleaned is as follows: the water distributor 130 sprays liquid onto the roller brush 120 to wet it. The wet roller brush 120 can clean the surface to be cleaned and absorb dirt. Then, dirt such as hair deep within the bristles of the roller brush 120 can be detached from the roller brush 120 by the action of the comb-tooth scraper 142. The dirt falls downwards under its own gravity and is sucked into the wastewater tank through the suction port 110a under negative pressure. Since the bristles of the roller brush 120 will be flattened to varying degrees by the action of the comb-tooth scraper 142, the scraper 141 can smooth the bristles of the roller brush 120 to facilitate the re-wetting of the roller brush 120. Because the toothed structure on the comb-like scraper 142 is not effective in evenly distributing and squeezing water from the roller brush 120, the scraper 141 can squeeze the wastewater on the roller brush 120 to expel it, thereby improving the cleaning effect of the roller brush 120. When the roller brush 120 passes through the water distributor 130 again to spray liquid, the clean roller brush 120 can continue to clean the surface to be cleaned, thus improving the cleaning effect.

[0156] In some examples, the distributor 130 can be connected to the brush body 110 via a pivot 143. The distributor 130 can be flipped toward the roller brush 120 to prevent the distance between the distributor 130 and the roller brush 120 from increasing and affecting the spraying effect on the roller brush 120 as the roller brush 120 wears down with long-term use and its size decreases. An effective spraying distance can be maintained between the distributor 130 and the roller brush 120.

[0157] In some examples, the distributor 130, scraper 141, and comb-tooth scraper 142 can all rotate relative to the rotating shaft 143. The flipping movements of the distributor 130, scraper 141, and comb-tooth scraper 142 can be independent of each other. Alternatively, the scraper 141 can be connected to the distributor 130. The scraper 141 and the distributor 130 can flip synchronously. Furthermore, the comb-tooth scraper 142 can be connected to the distributor 130, and the comb-tooth scraper 142 and the distributor 130 can flip synchronously. No specific limitations are made in this embodiment.

[0158] See also some of the possible implementation methods. Figure 2 As shown, in this embodiment of the application, the scraper 141 is disposed on the surface of the water distributor 130 facing the comb-tooth scraper 142.

[0159] In this embodiment, the scraper 141 and the water distributor 130 can rotate synchronously. Under the action of the second elastic member 152, the scraper 141 and the roller brush 120 can maintain an effective contact depth, and the water distributor 130 and the roller brush 120 can maintain an effective spraying distance. The scraper 141 can enter part of the fibers of the roller brush 120. There is a gap between the spray nozzle of the water distributor 130 and the roller brush 120, so that the spray nozzle can spray radially toward the roller brush 120, thereby increasing the spraying area.

[0160] See also some of the possible implementation methods. Figure 2 As shown, in this embodiment of the application, the scraper 141 can protrude from the surface of the water distributor 130 facing the roller brush 120.

[0161] In this embodiment, by setting the scraper 141 to protrude from the surface of the distributor 130 facing the roller brush 120, the scraper 141 can be inserted into the bristles of the roller brush 120, the scraper 141 and the roller brush 120 remain in contact, and the distributor 130 can guide the liquid onto the roller brush 120. In other words, the scraper 141 and the bristles of the roller brush 120 can maintain an effective contact depth, and there can be an effective spraying distance between the distributor 130 and the roller brush 120.

[0162] In some examples, the scraper 141 and the distributor 130 can be connected as a whole by means of, but not limited to, crimping, riveting, snap-fitting, fastener connection, etc.

[0163] For example, see Figures 4 to 6 As shown, the water distributor 130 may be provided with a connection structure 145 for connecting to the rotating shaft 143. The movement of the connection structure 145 relative to the rotating shaft 143 and the movement of the support 144 relative to the rotating shaft 143 can be independent of each other.

[0164] See also some of the possible implementation methods. Figure 2As shown, along the height direction Y of the floor brush body 110, there is a first gap 100a between the scraper 141 and the comb-tooth scraper 142. A first seal 160 is provided at the first gap 100a. The first seal 160 is used to prevent dirt from entering the floor brush body 110.

[0165] In this embodiment, the first gap 100a provides space for the rotation of the scraper 141 and the comb-tooth scraper 142, reducing the possibility of jamming during the rotation of the scraper 141 and the comb-tooth scraper 142. By providing a first seal 160 at the first gap 100a, the possibility of dirt carried up by the rotating roller brush 120 and dirt scraped off by the scraper 141 from the roller brush 120 entering the interior of the floor brush body 110 through the first gap 100a can be reduced.

[0166] It is easy to understand that since both the scraper 141 and the comb-tooth scraper 142 undergo a flipping motion, their movement paths are relatively small, and the dimension of the first gap 100a along the height direction Y of the brush body 110 can also be set to be relatively small. Correspondingly, the dimension of the first seal 160 along the height direction Y of the brush body 110 can also be set to be relatively small, which helps to save on the material cost of the first seal 160.

[0167] In some examples, the first seal 160 can be pressed between the scraper 141 and the comb-tooth scraper 142.

[0168] For example, when the roller brush 120 wears out after long-term use, the scraper 141 and the comb-tooth scraper 142 flip in the direction of the roller brush 120. At this time, the pressing effect of the scraper 141 and the comb-tooth scraper 142 on the first seal 160 can be increased, so that dirt can not easily enter the brush body 110.

[0169] In some examples, the first seal 160 may be in the form of a strip. The first seal 160 may extend along the axial direction Z of the brush 120.

[0170] See also some of the possible implementation methods. Figure 2 As shown, along the forward direction X of the floor brush body 110, the first sealing member 160 includes a primary sealing part 161 and a secondary sealing part 162 spaced apart. Along the height direction Y of the floor brush body 110, the two ends of the primary sealing part 161 abut against the scraper 141 and the comb-tooth scraper 142, respectively. Along the height direction Y of the floor brush body 110, the two ends of the secondary sealing part 162 abut against the scraper 141 and the comb-tooth scraper 142, respectively.

[0171] In this embodiment, since both the scraper 141 and the comb-tooth scraper 142 have a flipping motion, the primary sealing part 161 and the secondary sealing part 162 have different degrees of compression between the scraper 141 and the comb-tooth scraper 142. By providing the primary sealing part 161 and the secondary sealing part 162, a double seal for the first gap 100a can be achieved. If one of the primary sealing part 161 and the secondary sealing part 162 fails, the other can still perform the sealing function.

[0172] In some examples, the primary sealing part 161 and the secondary sealing part 162 are connected. The first sealing element 160 can be a one-piece structure. The longitudinal section of the first sealing element 160 can be U-shaped, wherein the longitudinal section is perpendicular to the Z-axis of the roller brush 120.

[0173] In some examples, the side of the comb blade 142 facing the scraper 141 may have a receiving groove for mounting the first seal 160. The first seal 160 may be fixed to the receiving groove.

[0174] See also some of the possible implementation methods. Figure 2 As shown, in this embodiment of the application, there is a second gap 100b between the comb-tooth scraper 142 and the brush body 110. A second seal 170 is provided at the second gap 100b. The second seal 170 is used to prevent dirt from entering the brush body 110.

[0175] In this embodiment, the toothed scraper 142 can be flipped toward the roller brush 120, and the second gap 100b provides space for the flipping movement of the toothed scraper 142. By providing a second seal 170 at the second gap 100b, the possibility of dirt stirred up by the rotation of the roller brush 120, dirt scraped off by the scraper 141 from the roller brush 120, and dirt detached from the roller brush 120 by the toothed scraper 142 entering the interior of the floor brush body 110 through the second gap 100b can be reduced.

[0176] In some examples, along the height direction Y of the brush body 110, the first seal 160 may be located above the comb bar 142, and the second seal 170 may be located below at least a portion of the comb bar 142.

[0177] See also some of the possible implementation methods. Figure 2 and Figure 6 As shown, the comb-tooth scraper 142 includes a comb tooth portion 1421 and a rear end limiting portion 1422. The comb tooth portion 1421 is used to contact the roller brush 120. Along the forward direction X of the floor brush body 110, the scraper 141 is located on the side of the rear end limiting portion 1422 facing the roller brush 120.

[0178] In this embodiment, the rear limiting part 1422 can limit the scraper 141 to reduce the possibility of the scraper 141 moving away from the roller brush 120 during the flipping of the comb scraper 142 and the flipping of the scraper 141.

[0179] Furthermore, when the second elastic element 152 fails, preventing the scraper 141 from flipping towards the roller brush 120, the first elastic element 151 applies a force towards the roller brush 120 to the comb-tooth scraper 142. This allows the rear end limiting portion 1422 of the comb-tooth scraper 142 to abut against the scraper 141, thereby pushing the scraper 141 towards the roller brush 120 through the rear end limiting portion 1422, ensuring that the scraper 141 and the roller brush 120 remain in contact. At this time, the scraper 141 and the roller brush 120 can have an effective contact depth to evenly distribute and squeeze water from the roller brush 120.

[0180] In some examples, the surface of the rear limiting portion 1422 facing the roller brush 120 may be provided with abutment ribs. The abutment ribs can be used to connect with the scraper 141.

[0181] In some examples, the comb teeth 1421 are used to contact the roller brush 120. The comb teeth 1421 may refer to the aforementioned tooth-like structure.

[0182] See also some of the possible implementation methods. Figure 2 As shown, the scraper 141 is inclined relative to the surface to be cleaned. Along the forward direction X of the floor brush body 110, the scraper 141 gradually increases in height.

[0183] In this embodiment, along the forward direction X of the floor brush body 110 from front to back, the scraper 141 can gradually tilt upward so that the liquid thrown out by the rotating roller brush 120 and the liquid squeezed by the scraper 141 are less likely to flow upward along the side wall of the scraper 141 into the interior of the floor brush body 110.

[0184] In some examples, at least part of the scraper 141 may be located in the area above the center line of the roller brush 120.

[0185] See also some of the possible implementation methods. Figure 2 As shown, the comb-tooth scraper 142 is inclined relative to the surface to be cleaned. Along the forward direction X of the floor brush body 110, the comb-tooth scraper 142 gradually increases in height.

[0186] In this embodiment, along the forward direction X of the floor brush body 110 from front to back, the comb-tooth scraper 142 can gradually tilt upwards, so that the liquid thrown out by the rotating roller brush 120 and the liquid squeezed by the scraper 141 from the roller brush 120 are less likely to flow upwards along the side wall of the comb-tooth scraper 142 into the interior of the floor brush body 110.

[0187] See also some of the possible implementation methods. Figure 1 As shown, in this embodiment of the application, the scraper 141 is located above the horizontal plane where the center line of the roller brush 120 is located.

[0188] In this embodiment, the scraper 141 is located above the horizontal plane containing the center line of the roller brush 120, and the contact point between the scraper 141 and the roller brush 120 is also located above the horizontal plane containing the center line of the roller brush 120. When the roller brush 120 rotates counterclockwise, the roller brush 120 can exert a force on the scraper 141 in the direction of the roller brush 120, so that the scraper 141 and the roller brush 120 can remain in contact when the wear diameter of the roller brush 120 decreases.

[0189] In some examples, the extension of scraper 141 may pass through the center of brush 120. Alternatively, the extension of scraper 141 may be located below the horizontal plane where the center of brush 120 is located.

[0190] When the extension line of the scraper 141 is above the horizontal plane where the center of the roller brush 120 is located, the counterclockwise rotation of the roller brush 120 and the action of the second elastic element 152 result in excessive contact force between the scraper 141 and the roller brush 120. This leads to a slower relative movement speed between the scraper 141 and the roller brush 120, and the scraper 141 directly contacts the root of the roller brush 120. Therefore, when the scraper 141 squeezes water from the root of the roller brush 120's fibers, the squeezing effect on areas far from the root is weak, easily leading to uneven squeezing of the roller brush 120's fibers, thus affecting the squeezing effect. Furthermore, excessive contact force between the scraper 141 and the roller brush 120 can increase the rotational resistance of the roller brush 120, potentially increasing the current of the drive motor used to drive the roller brush 120's rotation.

[0191] By setting the extension line of the scraper 141 to pass through the center of the roller brush 120, or by setting the extension line of the scraper 141 to be below the horizontal plane where the center of the roller brush 120 is located, the scraper 141 can first contact the middle part of the roller brush 120's fibers. Then, under the counterclockwise rotation of the roller brush 120 and the action of the second elastic element 152, the scraper 141 can gradually and quickly cause the fibers of the roller brush 120 to flatten and squeeze water from the entire fibers of the roller brush 120. This can improve the uniformity and fullness of water squeezing from the roller brush 120 and improve the water squeezing effect.

[0192] In some examples, the angle between the scraper 141 and the surface to be cleaned can be greater than or equal to 0° and less than or equal to 30°. For example, the angle can be 5°, 10°, 15°, etc.

[0193] This application provides a floor brush assembly 100. See also... Figures 7 to 10As shown, the floor brush assembly 100 includes a floor brush body 110, a roller brush 120, a water distributor 130, a scraper assembly 140, and a force-applying component 150.

[0194] The floor brush body 110 is provided with a suction port 110a. Along the forward direction X of the floor brush body 110, the roller brush 120 is located at the front end of the floor brush body 110, and the suction port 110a faces the roller brush 120.

[0195] A water distributor 130 is disposed on the brush body 110. The water distributor 130 is located above the suction port 110a, and the spray nozzle of the water distributor 130 faces the roller brush 120. At least a portion of the scraper assembly 140 is located above the suction port 110a. The scraper assembly 140 includes a comb-tooth scraper 142 and a scraper blade 141. The comb-tooth scraper 142 is slidably connected to the brush body 110. The scraper blade 141 is movably connected to the brush body 110.

[0196] The force-applying component 150 is connected to the scraper assembly 140. The force-applying component 150 is used to drive the comb-tooth scraper 142 and the scraper 141 to move in the direction of the roller brush 120, so that the scraper 141 and the comb-tooth scraper 142 both abut against the roller brush 120.

[0197] In this embodiment, the toothed scraper 142 can slide towards the roller brush 120 under the action of the force-applying member 150, so that the toothed scraper 142 and the roller brush 120 remain in contact. Therefore, after the roller brush 120 wears down from long-term use, the force-applying member 150 can maintain the interaction force between the toothed scraper 142 and the roller brush 120, and there is an effective contact depth between the toothed scraper 142 and the roller brush 120, so as to improve the stability and reliability of removing dirt such as hair from the roller brush 120 and ensure the cleaning effect.

[0198] Specifically, by applying a force to the comb blade 142 in the direction of the roller brush 120 through the force-applying member 150, the comb blade 142 and the roller brush 120 can always have an effective contact depth. In particular, when the roller brush 120 is worn and its size is reduced, the comb blade 142 can move in the direction of the roller brush 120 to maintain the effective contact depth between the comb blade 142 and the roller brush 120.

[0199] It should be noted that in this embodiment, the toothed scraper 142 is slidably connected to the brush body 110, and the movement trajectory of the toothed scraper 142 is linear. As the roller brush 120 wears down over time, its diameter will decrease. By setting the toothed scraper 142 to slide relative to the brush body 110, the angle between the toothed scraper 142 and the roller brush 120 remains constant while they are in contact, thus ensuring the stability and reliability of the toothed scraper 142 in removing hair and other dirt from the roller brush 120.

[0200] In some examples, the toothed scraper 142 can slide along the forward direction X of the brush body 110. Alternatively, the toothed scraper 142 can have an angle relative to the surface to be cleaned, which is not limited in this embodiment.

[0201] It should be noted that, in this embodiment, the scraper 141 is movably connected to the brush body 110. This can mean, but is not limited to, that the scraper 141 can be rotated relative to the brush body 110 towards the roller brush 120, or that the scraper 141 can slide relative to the brush body 110 towards the roller brush 120. No specific limitations are made in this embodiment.

[0202] The scraper 141, under the action of the force-applying component 150, can move towards the roller brush 120. The scraper 141 can fit tightly against the roller brush 120 to exert a uniform water-distributing force on the brush bristles. Liquid in areas with high liquid content on the roller brush 120 can diffuse outwards under the squeezing action of the scraper 141, thereby improving the uniformity of liquid distribution on the roller brush 120, increasing the drying efficiency of the surface to be cleaned, and reducing the possibility of watermarks formed on the surface after drying.

[0203] Furthermore, since the scraper 141 exerts a force towards the roller brush 120, the scraper 141 and the roller brush 120 have a certain contact depth, allowing the scraper 141 to also have a water-squeezing effect on the roller brush 120. Through the water-squeezing effect of the scraper 141 on the roller brush 120, on the one hand, the water content inside the roller brush 120 can be reduced, thereby improving the drying efficiency of the surface to be cleaned and reducing the possibility of water stains forming on the surface to be cleaned by the roller brush 120. On the other hand, when the roller brush 120 generates dirt while cleaning the surface to be cleaned, the scraper 141 can squeeze out the wastewater inside the roller brush 120, and the wastewater can enter the wastewater tank through the suction port 110a. Therefore, the scraper 141 can have a certain cleaning effect on the roller brush 120.

[0204] When the roller brush 120 wears out after long-term use, the force-applying component 150 can ensure an effective contact depth between the scraper 141 and the roller brush 120, so as to maintain the water-spreading and squeezing force of the scraper 141 and the roller brush 120. This can reduce the possibility that the water-spreading and squeezing force of the scraper 141 on the roller brush 120 will be reduced, thus affecting the cleaning effect on the surface to be cleaned.

[0205] In some possible implementations, the comb-tooth scraper 142 includes a comb tooth portion 1421 and a rear end limiting portion 1422. The comb tooth portion 1421 is used to contact the roller brush 120, and along the forward direction X of the floor brush body 110, the end of the scraper 141 away from the roller brush 120 abuts against the rear end limiting portion 1422.

[0206] In this embodiment, the rear limiting part 1422 can limit the scraper 141 so that during the sliding of the comb scraper 142 and the movement of the scraper 141, the rear limiting part 1422 prevents the scraper 141 from moving away from the roller brush 120.

[0207] Furthermore, after the roller brush 120 wears out over a long period of use, when the scraper 141 can no longer move in the direction of the roller brush 120, the comb-tooth scraper 142 slides in the direction of the roller brush 120, so that the rear end limiting part 1422 of the comb-tooth scraper 142 abuts against the scraper 141. Thus, the rear end limiting part 1422 pushes the scraper 141 to move in the direction of the roller brush 120, and the scraper 141 and the roller brush 120 can remain in contact.

[0208] See also some of the possible implementation methods. Figure 8 As shown, the force-applying component 150 may include a first elastic component 151. One end of the first elastic component 151 is connected to the comb-tooth scraper 142. The other end of the first elastic component 151 is connected to the floor brush body 110. The first elastic component 151 is used to drive the comb-tooth scraper 142 to maintain contact with the roller brush 120, and to keep the scraper 141 in contact with the roller brush 120.

[0209] In this embodiment, the first elastic member 151 can be used to provide a sliding force to the comb bar 142 toward the roller brush 120, so that after the roller brush 120 is worn down by long-term use, the comb bar 142 and the roller brush 120 can maintain a relative force, thereby ensuring the cleaning effect of the comb bar 142 on the hair and other dirt on the roller brush 120.

[0210] The first elastic element 151 can always exert an elastic force on the comb-tooth scraper 142, pushing it towards the roller brush 120. The first elastic element 151 has a simple structure, good reliability, and is easy to install and maintain.

[0211] In some examples, when the scraper 141 slides relative to the brush body 110, the scraper 141 and the comb-tooth scraper 142 can move synchronously. At this time, the first elastic element 151 can be used to provide a force toward the roller brush 120 to the scraper 141 and the comb-tooth scraper 142.

[0212] In other examples, the scraper 141 and the comb-tooth scraper 142 can also be independent of each other when the scraper 141 slides relative to the brush body 110.

[0213] The force-applying component 150 may include a second elastic component 152. One end of the second elastic component 152 is connected to the scraper 141. The other end of the second elastic component 152 is connected to the brush body 110. The second elastic component 152 can be used to drive the scraper 141 to maintain contact with the roller brush 120. This ensures that after long-term use of the roller brush 120, a relative force can be maintained between the scraper 141 and the roller brush 120, thereby guaranteeing the water distribution and squeezing effect of the scraper 141 on the roller brush 120.

[0214] The first elastic element 151 and the second elastic element 152 can be independent of each other.

[0215] In some other examples, the scraper 141 can be flipped relative to the brush body 110 toward the roller brush 120. The second elastic element 152 can provide the scraper 141 with a force that flips it toward the roller brush 120.

[0216] Therefore, the first elastic element 151 and the second elastic element 152 can independently drive the comb-tooth scraper 142 and the scraper 141 to maintain contact with the roller brush 120, so that if one of them fails, the other can operate normally. The user or staff can perform maintenance on the one that fails individually.

[0217] See also some of the possible implementation methods. Figure 8 and Figure 10 As shown, the floor brush body 110 is provided with a groove 110b for the scraper 141 to slide, so that when the comb-tooth scraper 142 rotates toward the roller brush 120, the scraper 141 slides along the groove 110b toward the roller brush 120. The comb-tooth scraper 142 abuts against the roller brush 120.

[0218] In this embodiment, the groove 110b can provide guidance for the sliding of the comb bar 142, so that the comb bar 142 can slide stably in the direction of the roller brush 120, which helps to maintain the tilt angle of the comb bar 142 relative to the roller brush 120, thereby ensuring the removal effect of hair and other dirt on the roller brush 120.

[0219] In some examples, the scraper assembly 140 may include a support 146. The support 146 is connected to the toothed scraper 142. At least one end of the support 146 may engage with a groove 110b along the axial direction Z of the roller brush 120 to allow the toothed scraper 142 to slide relative to the brush body 110.

[0220] The support member 146 can extend along the axial direction Z of the roller brush 120. The end of the support member 146 can be inserted into the groove 110b and slide within the groove 110b. The connection between the support member 146 and the comb blade 142 can also improve the structural strength of the comb blade 142. The support member 146 can be, but is not limited to, a metallic material.

[0221] In some examples, the support 146 may be plate-shaped. The support 146 may be located below at least a portion of the comb blade 142 to provide support for the comb blade 142.

[0222] In some examples, the extension direction of the groove 110b may be parallel to the surface to be cleaned, or the groove 110b may be inclined at a certain angle relative to the surface to be cleaned.

[0223] In some examples, the extension of the groove 110b toward the brush 120 may be close to or through the center line of the brush 120.

[0224] See also some of the possible implementation methods. Figure 8 As shown, the scraper 141 is rotatably connected to the brush body 110. The scraper 141 has a rolling motion toward the roller brush 120.

[0225] In this embodiment, the comb-tooth scraper 142 can slide relative to the brush body 110, and the scraper 141 can rotate relative to the brush body 110. Therefore, the sliding motion of the comb-tooth scraper 142 and the rotating motion of the scraper 141 can be independent of each other. The comb-tooth scraper 142 and the scraper 141 are less likely to interfere with each other. Furthermore, when one of them malfunctions, the other can continue to operate normally.

[0226] In particular, when the comb-tooth scraper 142 malfunctions, it becomes difficult for the comb-tooth scraper 142 to achieve a cleaning effect on the roller brush 120. The scraper 141 can remain in contact with the roller brush 120 so that the roller brush 120 can be cleaned by the scraper 141.

[0227] In some examples, scraper 141 can be connected to shaft 143 via connection structure 145.

[0228] This application provides a cleaning device, which may include a body and the floor brush assembly 100 in any of the above embodiments.

[0229] The floor brush assembly 100 is connected to the main body. During operation of the cleaning equipment, the user can push the main body to move the floor brush assembly 100 forward or backward.

[0230] The cleaning device provided in this application embodiment allows the scraper 141 and the roller brush 120 to maintain contact. In particular, when the roller brush 120 wears down due to long-term use, causing its size to decrease, the force-applying member 150 ensures an effective contact depth between the scraper 141 and the roller brush 120. A relative force is maintained between the scraper 141 and the roller brush 120, allowing the scraper 141 to still effectively distribute and squeeze water from the roller brush 120.

[0231] The water-distributing effect ensures even liquid distribution on the roller brush 120, reducing the likelihood of excessive liquid in certain areas causing watermarks on the surface to be cleaned. The scraper 141's squeezing action on the roller brush 120 reduces its water content, further minimizing the possibility of water stains on the surface. Furthermore, when the roller brush 120 becomes dirty while cleaning, the scraper 141 can squeeze out the wastewater from within it.

[0232] The toothed scraper 142 and the roller brush 120 can maintain contact. When the roller brush 120 wears down due to long-term use, causing its size to decrease, the force-applying element 150 ensures an effective contact depth between the toothed scraper 142 and the roller brush 120. The relative force between the toothed scraper 142 and the roller brush 120 improves the stability and reliability of removing hair and other dirt from the roller brush 120, ensuring a good cleaning effect.

[0233] In addition, the scraper assembly 140 includes a scraper 141 and a comb-tooth scraper 142, and the scraper 141 can squeeze out sewage. Therefore, when the comb-tooth scraper 142 fails, the scraper 141 can squeeze out sewage and other dirt in the roller brush 120 while providing water evenness to the roller brush 120, thereby achieving a cleaning effect on the roller brush 120.

[0234] In some examples, the cleaning equipment may also include a clean water tank and a wastewater tank. The clean water tank and wastewater tank may be mounted on the floor brush assembly 100 or on the main body. Alternatively, one of the clean water tank and wastewater tank may be mounted on the floor brush assembly 100, and the other may be mounted on the main body. No limitation is made in the embodiments of this application.

[0235] This application provides a cleaning system, which may include a base or a base station. Cleaning equipment may be placed on the base or base station.

[0236] In some examples, the base can be used to clean and dry the roller brush 120 to prevent the roller brush 120 from being damp for a long time, which could lead to odors or bacteria.

[0237] In some examples, the base station may have a charging function. When the cleaning equipment is placed on the base station, it can be charged and automatically have water supplied and drained. The base and the base station can be separate structures, or they can be an integrated structure; this is not limited in the embodiments of this application.
