Description

Technical Field

[0001] This application relates to the field of cleaning equipment, and more particularly to a cleaning device. Background Technology

[0002] With the continuous advancement of technology and the increasing demands of consumers, floor scrubbers are being used more and more widely. The core component of a floor scrubber is the roller brush. When the floor scrubber is working, the roller brush rotates at high speed to remove dirt and impurities from the floor through physical contact and friction.

[0003] However, most floor scrubbers on the market currently suffer from the problem of hair tangling on the roller brush, failing to effectively prevent hair from getting tangled on the brush. Some products use plastic to make the brush bristles in an attempt to solve this problem, but this material is less effective at preventing tangling with longer hairs. Summary of the Invention

[0004] The purpose of this application is to provide a cleaning device that can reduce the entanglement of long hair on the roller brush.

[0005] To achieve the above objectives, this application provides a cleaning device, which includes at least a cleaning component. The cleaning component includes a roller brush and a scraper assembly, wherein the scraper assembly includes a comb plate and a squeegee, both of which are in contact with the roller brush. The squeegee is used to scrape dirt off the roller brush. In a rotational path in a first direction, the roller brush first passes the comb plate and then the squeegee. The comb plate includes comb teeth that extend away from the squeegee. The squeegee has a squeegee end at its end, and the thickness of the squeegee end is greater than the thickness of the comb teeth end.

[0006] Therefore, the technical solution provided in this application includes a cleaning device comprising a roller brush, a comb plate, and a squeegee. Both the squeegee and the comb plate make interference contact with the bristles of the roller brush, and the squeegee is used to scrape dirt off the roller brush. The squeegee and the comb plate are positioned vertically to ensure that when the roller brush rotates in the first direction, it passes the comb plate first and then the squeegee. This allows the comb plate to first cut and separate the long hair entangled on the roller brush using its teeth, and then the squeegee squeezes the bristles to remove impurities, wastewater, and other dirt mixed in with the bristles. Simultaneously, the comb teeth also comb and organize the bristles to facilitate the subsequent squeegee operation. Through the coordinated work of the comb plate and the squeegee, this application can reduce the entanglement of long hair on the roller brush and further improve the cleaning efficiency of the roller brush.

[0021] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings. Terms used in this application to indicate spatial relative positions, such as “above,” “over,” “below,” “under,” “first end,” “second end,” “one end,” and “other end,” are used for ease of explanation to describe the relationship of one unit or feature relative to another unit or feature as shown in the accompanying drawings. The terms of spatial relative positions may be intended to include different orientations of the device in use or operation other than those shown in the figures. For example, if the device in the figures is flipped, a unit described as being “below” or “under” other units or features would be located “above” other units or features. Therefore, the exemplary term “below” can encompass both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or other orientations), and the spatially related descriptive terms used herein will be interpreted accordingly.

[0022] Furthermore, the terms "installation," "setup," "equipped with," "connection," "sliding connection," "fixed," and "sleeve connection" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0023] With the continuous advancement of technology, people's living standards have greatly improved, and more and more families are starting to use various cleaning equipment to reduce labor intensity and improve their quality of life. Because floor scrubbers can clean floors quickly and thoroughly, they are widely used in commercial, industrial, and residential environments.

[0024] The roller brush is the rotating component in a floor scrubber used to contact and clean the floor; it is the core component of the machine. During operation, the roller brush rotates at high speed, removing dirt and impurities from the floor through physical contact and friction. However, a common problem with existing floor scrubbers is that the roller brush becomes entangled with hair. As the brush rotates, it easily gets tangled in long, thin objects such as hair. This tangled hair hinders contact between the brush and the floor, reducing friction and thus decreasing cleaning effectiveness. Furthermore, the tangled hair causes uneven pressure on the brush, accelerating wear and shortening its lifespan.

[0025] To address the issue of bristle tangling in roller brushes, some manufacturers use polyester fibers, nylon, and other plastic materials to make the bristles. Because plastic bristles typically have a smooth surface, short hairs are less likely to adhere to or entangle on them. However, plastic bristles have poor water absorption, meaning that in wet or damp cleaning environments, the bristles cannot effectively absorb and retain moisture, leaving water stains on the cleaned surface and reducing the cleaning effectiveness of the roller brush. Furthermore, because plastic materials are prone to static electricity, long hairs or a large amount of hair are more likely to entangle on the bristles.

[0026] Therefore, how to improve the structure of floor scrubbers to reduce the entanglement of long hair on the roller brush while ensuring the cleaning effect of the existing roller brush has become an urgent issue to be addressed in this field.

[0027] To address the aforementioned problems, this application provides a cleaning device, specifically a floor scrubber, a robotic vacuum cleaner, or other equipment equipped with a roller brush. To facilitate understanding of the solution provided, a floor scrubber will be used as an example to briefly explain the structure and working principle of the cleaning device. Figure 1 , Figure 2 and Figure 3 As shown, a floor scrubbing machine mainly consists of a body system, a cleaning system, a fluid supply system, a dirt and grime recovery system, and an energy system.

[0028] The machine system consists of a handle 3, a body 4, and a floor brush 5. The body 4 is typically designed to be upright, and the handle 3 is mounted on the body 4 for a comfortable grip during cleaning. The handle 3 usually contains control buttons or switches used to start the machine, adjust cleaning power, or control other functions of the floor scrubber. The floor brush 5 is the part that directly contacts the floor, tile, or other surfaces to be cleaned, and it is rotatably connected to the body 4. Under the operator's control, the floor brush 5 can move freely on the surface to be cleaned. Simultaneously, the operator can control the direction of movement and working status of the floor brush 5 by holding the handle 3, and switch the floor scrubber between upright and tilted positions to adapt to different cleaning needs.

[0029] The cleaning system includes a cleaning component and a drive motor. The cleaning component is typically housed in the floor brush 5 and includes one or more rotating roller brushes 11. These roller brushes 11 rotate under the drive motor to pick up dirt from the surface to be cleaned. The bristles of the roller brushes 11 are typically made of materials such as cloth, nylon, polypropylene, or metal wire. The operator can choose different types of roller brushes according to different cleaning needs. For example, cloth roller brushes are suitable for cleaning smooth floors, while nylon roller brushes are suitable for cleaning rough floors or floors with stubborn stains. When cleaning tile floors, the operator can use a cloth roller brush; when cleaning cement floors, the operator can use a nylon roller brush.

[0030] The fluid supply system consists of a clean water tank, a water pump, and a fluid distributor 2. The clean water tank stores clean water or water with added detergent, providing the necessary liquid for the cleaning process. The water pump draws cleaning media from the clean water tank and delivers it to the fluid distributor 2 through pipes. The fluid distributor 2 is responsible for evenly spraying the cleaning media onto the roller brush 11 or the surface to be cleaned, softening the dirt and thus helping the roller brush 11 pick up dirt more effectively.

[0031] The dirt recovery system consists of a wastewater tank, a recovery channel, a suction port, and a suction motor. The suction port is located near the roller brush 11 and is connected to the suction motor, responsible for sucking up the dirt picked up by the roller brush 11. The suction motor generates strong suction to lift the dirt from the ground and send it into the wastewater tank through the recovery channel. Specifically, the bottom of the floor brush 5 is equipped with a floor scraper 51, which is used to contact the surface to be cleaned. The floor scraper 51 is parallel to the axis of the roller brush 11, and its extension length is basically the same as the length of the roller brush 11. When the floor scrubber is performing a floor cleaning task, the suction motor works, and a negative pressure area is formed between the roller brush 11 and the floor scraper 51. The suction port is located in this area. A damp roller brush 11 wipes the floor, picking up dirt. As the roller brush 11 rotates, the dirt on it is scraped off by a scraper bar located in area A (in some scenarios, the centrifugal force generated by the high-speed rotation of the roller brush 11 can also detach the dirt from the brush). The scraper bar is positioned above the suction port, and the scraped-off dirt and other solid-liquid mixture is then sucked into the suction port. A recovery channel connects the suction port and the wastewater tank, used to transfer dirt from the floor to the wastewater tank. The wastewater tank is used to store dirty water and dirt picked up during the cleaning process.

[0032] The energy system typically includes a rechargeable battery, such as a lithium-ion battery or a nickel-cadmium battery, which provides the necessary power to the water pump, suction motor, and drive motor, allowing the floor scrubber to operate without the constraints of a power cord and ensuring that it can efficiently complete cleaning tasks in environments far from electrical outlets.

[0033] When the floor scrubber is in operation, the operator can control the machine body 4 and floor brush 5 via handle 3, allowing it to contact the surface to be cleaned in an upright or tilted position. The machine body 4 contains a rechargeable battery that powers the entire machine, while the roller brush 11 in the floor brush 5 directly contacts the ground, picking up dirt by rotating. Cleaning media in the clean water tank is pumped to the fluid distributor 2 and then evenly sprayed onto the roller brush 11 or the surface to be cleaned. Simultaneously, the dirt recovery system activates; the suction motor generates suction, drawing in the dirt picked up by the roller brush 11 through the suction port and transporting it to the wastewater tank through the recovery channel.

[0034] Please refer to this as well. Figures 3 to 13In one feasible embodiment, the cleaning device includes at least a cleaning assembly comprising a roller brush 11 and a scraper assembly, wherein the scraper assembly consists of a comb plate 12 and a squeegee 13. Both the comb plate 12 and the squeegee 13 extend in a direction parallel to the axial direction of the roller brush 11, and both the comb plate 12 and the squeegee 13 are in contact with the roller brush 11 throughout the entire axial direction.

[0035] The comb plate 12 and the wiper plate 13 are arranged adjacent to each other, and their vertical position is related to the rotation direction of the roller brush 11. Specifically, when the roller brush 11 rotates in a first direction, it passes the comb plate 12 first and then the wiper plate 13 along its rotation path. For example, with... Figure 3 The shown viewpoint is for reference. If the first rotation direction of the roller brush 11 is clockwise, then the comb plate 12 is located below the wiper plate 13 to ensure that when the roller brush 11 rotates clockwise, it passes the comb plate 12 first and then the wiper plate 13. If the first rotation direction of the roller brush 11 is counterclockwise, then the comb plate 12 is located above the wiper plate 13 to ensure that when the roller brush 11 rotates counterclockwise, it passes the comb plate 12 first and then the wiper plate 13. This application uses a clockwise rotation direction as an example for explanation; correspondingly, the comb plate 12 is located below the wiper plate 13.

[0036] The wiper blade 13 has a wiping end 131 at its end, which makes an interference fit with the bristles of the roller brush 11. The wiper blade 13 is used to scrape dirt off the roller brush 11. Furthermore, to prevent hair from getting tangled on the roller brush 11, this application uses a comb plate 12 to cut and comb the hair on the roller brush 11. The comb plate 12 can be fixed to the underside of the wiper blade 13 using bolts or rivets. The end of the comb plate 12 has a comb tooth end 121 that extends away from the wiper blade 13. The comb tooth end 121 makes an interference fit with the bristles of the roller brush 11, meaning that the comb tooth end 121 at least partially extends into the bristles.

[0037] In this embodiment, the wiper blade 13 is used to scrape dirt off the roller brush 11, and the comb plate 12 is used to cut and comb the hair wrapped around the roller brush 11. Since the wiper blade 13 is in interference contact with the roller brush 11 along its entire axial length, if the thickness of the wiper blade 13 is too small, the rotational force of the roller brush 11 will cause the wiper blade 13 to vibrate. This prevents the wiper blade 13 from maintaining a stable interference contact with the bristles of the roller brush 11 throughout its entire axial length, potentially resulting in weak contact points and ultimately affecting the wiping effect. However, if the thickness of the wiper blade 13 is too large, the wiper blade 13 will apply excessive pressure to the roller brush 11 during rotation, which will affect the rotational speed of the roller brush 11 and may cause the drive motor of the roller brush 11 to overheat, affecting the overall performance of the machine. Similarly, if the thickness of the comb plate 12 is too large, it will affect the combing effect. If the thickness of the comb plate 12 is too small, it may break due to insufficient strength when it comes into contact with the rotating roller brush 11. Therefore, taking into account both the cleaning effect and the combing effect, this application designs the thickness of the squeegee end 131 to be greater than the thickness of the comb tooth end 121.

[0038] Optionally, the comb plate 121 is made of metal, and its comb end 121 includes a plurality of comb teeth 1212 arranged along the axial direction of the roller brush 11. The length of the comb teeth 1212 is 1.3 mm to 3 mm, and the thickness of the comb teeth 1212 is 0.5 mm to 1.5 mm. The shape of the comb teeth 1212 can be constructed as trapezoidal teeth or square teeth. When the roller brush 11 rotates, the aforementioned serrated comb teeth can cut and pull the long hairs wrapped in the brush bristles into short hairs, and comb the cut short hairs off the brush bristles. At the same time, the regular arrangement design of the comb teeth 1212 can also sort and orient the short hairs and brush bristles. Then, under the suction of the suction motor, the sorted short hairs and unbroken long hairs will be quickly sucked into the suction port through the gaps between the comb teeth.

[0039] It should be noted that the interference fit between the comb teeth 121 and the bristles is less than that between the squeegee end 131 and the bristles. The shorter insertion distance of the comb teeth 121 reduces excessive pulling on the bristles, helping to protect the bristles and extend their lifespan. The longer insertion distance of the squeegee end 131 allows for deeper contact with the bristles, helping to collect and recycle dirt and moisture from deeper layers.

[0040] It is worth noting that, considering many cleaning devices are equipped with squeegees, to fully utilize the existing squeegee installation space, the original squeegee can be split into two parts: a squeegee 13 and a comb plate 12. Both the squeegee 13 and the comb plate 12 are sheet metal parts, and the squeegee 13 is thinner than the original squeegee to ensure that the total sheet metal thickness is the same as the original squeegee thickness after the comb plate 12 and squeegee 13 are fitted together. This allows the comb plate 12 and squeegee 13 to be installed in the original squeegee installation space without changing it, maintaining compatibility with the existing equipment. The close fit between the comb plate 12 and squeegee 13 also helps maintain overall strength. Furthermore, with the squeegee 13 positioned above the comb plate 12, the squeegee 13 and comb plate 12 work together to provide additional anti-hair tangling capabilities while maintaining the original squeegee performance. The comb plate 12 and the wiper blade 13 can be made of metal materials such as aluminum and stainless steel to balance toughness and durability. The thickness of the wiper blade 13 and the thickness of the comb plate 12 will be described in detail later.

[0041] like Figure 3 As shown, in practical applications, the roller brush 11 is usually positioned at the very front of the floor brush 5 to improve cleaning efficiency and optimize the cleaning path, while the recovery channel and suction port are located in the middle of the floor brush 5, behind the roller brush 11, to facilitate the arrangement of various recovery pipelines. In this structure, the roller brush 11 needs to rotate clockwise (to... Figure 3 The view shown is for reference. The roller brush 11 first passes through the squeegee 13 and then through the water outlet 21 of the fluid distributor 2, thereby sweeping the dirt off the ground and pushing it towards the middle of the floor brush 5, so as to facilitate the dirt and sewage recovery system to recover the dirt and sewage.

[0042] In this embodiment, since the comb plate 12 is located below the wiper plate 13, and considering the clockwise rotation of the roller brush 11, the comb tooth end 121 is designed to extend away from the wiper plate 13, so that the orientation of the serrated comb tooth edges is opposite to the rotation direction of the roller brush 11. When the roller brush 11 rotates, it passes through the comb plate 12 first and then the wiper plate 13, allowing the comb teeth on the comb tooth end 121 to better comb the hair in the bristles and remove it.

[0043] To ensure that the force applied by the comb tip 121 to the roller brush 11 is uniformly distributed, in one feasible embodiment, the contact posture between the comb tip 121 and the roller brush 11 can be designed such that the plane M1 containing the end face of the comb tip 121 is tangent to the first circle ⊙1, where the center of the first circle ⊙1 is the center point a of the roller brush 11. The radius of the first circle ⊙1 can be set with reference to the radius of the second circle ⊙2, where the radius of the second circle ⊙2 is the radius of the roller brush 11 when the bristles are fully extended, and the specific value of the radius of the second circle ⊙2 is the distance from the center point a to the outermost edge of the bristles. Since the comb tip 121 and the bristles of the roller brush 11 are in interference contact, it is necessary to ensure that the plane M1 containing the end face of the comb tip 121 extends into the bristles according to a preset value, that is, the radius of the first circle ⊙1 is smaller than the radius of the second circle ⊙2. It should be noted that the bristles on the roller brush 11 being fully extended can be understood as the roller brush 11 never getting wet after leaving the factory. Therefore, the radius of the second circle ⊙2 corresponds to the radius of the roller brush 11 when it first left the factory.

[0044] After a period of use, the bristles of the roller brush 11 will shorten due to wear. Compared to its initial condition, the distance from the center point a of the roller brush 11 to the outermost edge of the bristles will decrease. To ensure that the comb teeth 121 can still maintain interference contact with the bristles after a period of use, the radius of the first circle ⊙1 can be further limited. Specifically, a circle is drawn with the distance from the center point a of the roller brush 11 to the outermost edge of the bristles after half of the roller brush's lifespan has passed (this circle is referred to as the third circle ⊙3 for distinction). The radius of the third circle ⊙3 is smaller than the radius of the second circle ⊙2, and the radius of the first circle ⊙1 is smaller than the radius of the third circle ⊙3. It should be noted that the interference between the plane M1 containing the end face of the comb teeth 121 and the bristles will be explained in detail later.

[0045] When the plane M1 containing the end face of the comb teeth 121 is tangent to the first circle ⊙1, the force exerted by the comb teeth 121 on the roller brush 11 will be evenly distributed along the tangent. This can reduce excessive local pressure from the comb teeth 121 on the roller brush 11 and avoid local damage to the bristles. At the same time, the tangency between the plane M1 containing the end face of the comb teeth 121 and the first circle ⊙1 also allows the edges of the comb teeth to make smooth contact with the bristles, which is beneficial for the comb teeth to comb and guide messy hair.

[0046] In one feasible embodiment, the comb plate 12 includes a comb plate extension 123, and comb tooth ends 121 bend and extend from the comb plate extension 123 in a direction away from the wiper plate 13. In other words, the comb tooth ends 121 are connected to the end of the comb plate extension 123, and the connection between the comb tooth ends 121 and the comb plate extension 123 has a bending structure that causes the comb tooth ends 121 to extend in a direction away from the wiper plate 13. For ease of description, the connection between the comb tooth ends 121 and the comb plate extension 123 is referred to as the bend.

[0047] Furthermore, the end face of the comb tooth end 121 is provided with multiple slots 1211 to form multiple comb teeth 1212. In practical applications, the arrangement pattern of the slots 1211 can first be designed based on the performance requirements of the comb tooth plate 12. The arrangement pattern includes the number, shape, size of the slots 1211 and the spacing between each slot 1211. Then, slots are cut on the end face of the comb tooth end 121 using methods such as laser cutting, die stamping or tool cutting to form slots 1211. The slots 1211 penetrate from one side of the comb tooth end 121 to the other side to form a through opening that completely penetrates the material body. A comb tooth 1212 can be formed between two adjacent slots 1211.

[0048] Meanwhile, to prevent sewage, hair, and other contaminants from accumulating at the bend, the groove 1211 can extend all the way to the bend. In this structure, the bend is also covered by the groove 1211, meaning there is also a gap at the connection between the comb tooth end 121 and the outer extension 123 of the comb plate. Therefore, sewage, hair, and other contaminants at the bend can be quickly sucked into the suction port through the aforementioned gap.

[0049] Furthermore, the slot 1211 extends to the outer extension section 123 of the comb plate and partially extends into the outer extension section 123 of the comb plate. In other words, with Figure 10 With reference to the shown viewpoint, the slot 1211 extends upward from the lowest point of the comb tooth end 121 (i.e., the free end of the comb tooth 1212) to the outer extension section 123 of the comb plate, thus forming a long slot that runs through the entire end face height of the comb tooth end 121. In this structure, part of the structure of the outer extension section 123 of the comb plate is also covered by the slot 1211, that is, there is also a gap on the outer extension section 123 of the comb plate.

[0050] Since the comb tooth end 121 is located at the end of the comb tooth plate extension 123, the connection point between the comb tooth end 121 and the comb tooth plate extension 123 is the end of the comb tooth plate extension 123, which obviously has a notch. With this structure, when the comb tooth plate 12 and the wiper blade 13 are assembled together, even if the comb tooth plate extension 123 and the wiper blade extension 133 are tightly fitted together, there will still be a partial notch at the end of the comb tooth plate extension 123. This means that when wastewater and hair on the roller brush 11 detach from the bristles, they can be quickly sucked into the suction port through the aforementioned notch, instead of remaining at the bend (i.e., the connection point between the comb tooth end 121 and the comb tooth plate extension 123). Simultaneously, since wastewater will not remain at the bend, the water content of the roller brush 11 can be reduced, keeping the roller brush 11 at a certain degree of dryness, and the roller brush 11 will not increase water stains on the ground when cleaning.

[0051] In one feasible embodiment, the wiper blade 13 includes a wiper blade extension 133. The end of the wiper blade extension 133 (i.e., the end of the wiper blade extension 133 near the roller brush 11) constitutes a wiping end 131. Further, the wiper blade extension 133 is in contact with the comb plate extension 123, and the slot 1211 extends to be in contact with the wiper blade extension 133 to ensure that even if the wiper blade extension 133 obstructs the comb plate extension 123, there is no obstruction at the contact point between the wiper blade extension 133 and the comb plate extension 123, and sewage, hair, and other dirt at the bend can be smoothly sucked into the suction port through the slot 1211.

[0052] Optionally, the comb plate 12 is attached to the wiper blade 13, and the thickness of the wiper blade 13 is greater than the thickness of the comb plate 12.

[0053] In one feasible embodiment, the comb plate 12 includes a comb plate body 122 and a comb plate extension 123, with the comb tooth end 121 disposed at the end of the comb plate extension 123. A first angle α1 exists between the extending direction of the comb plate body 122 and the extending direction of the comb plate extension 123, and a second angle α2 exists between the extending direction of the comb tooth end 121 and the extending direction of the comb plate extension 123, wherein the degree measure of the first angle α1 is not equal to the degree measure of the second angle α2. The presence of the first angle α1 and the second angle α2 can change the stress distribution of the comb plate 12 under stress, helping the comb plate 12 to disperse and absorb force in multiple directions, thereby expanding the elastic response range of the comb plate 12. Ultimately, this allows the comb plate 12 to more effectively adapt to forces in different directions, improving its flexibility and efficiency during the combing process. Meanwhile, the segmented design of the comb plate body 122, the comb plate extension 123, and the comb end 121 can also enable independent optimization of different parts of the comb plate 12 to better adapt to the narrow installation space below the fluid distributor 2 and ensure that the relevant parameter requirements of the comb end 121 are met in the limited installation space.

[0054] It should be noted that the comb plate body 122, the comb plate extension 123, and the comb tooth end 121 can be integrally formed. For example, a single strip of metal can be rolled to form the comb plate body 122, the comb plate extension 123, and the comb tooth end 121. Alternatively, the comb plate body 122, the comb plate extension 123, and the comb tooth end 121 can be integrally formed using a casting process. Of course, the comb plate body 122, the comb plate extension 123, and the comb tooth end 121 can also be manufactured in sections and then welded together. This application does not limit the manufacturing process of the comb plate 12.

[0055] In one feasible embodiment, the wiper blade 13 has a wiper blade body 132 and a wiper blade extension 133. The end of the wiper blade extension 133 (i.e., the end of the wiper blade extension 133 near the roller brush 11) constitutes a wiping end 131. Further, the included angle α3 between the extending direction of the wiper blade body 132 and the extending direction of the wiper blade extension 133 is the same as the first included angle α1, that is, the wiper blade 13 has a shape similar to the comb plate 12. The above structural design allows the wiper blade body 132 to fit tightly with the comb plate body 122, and also allows the wiper blade extension 133 to fit tightly with the comb plate extension 123, thereby minimizing the total sheet metal thickness after the comb plate 12 and the wiper blade 13 are fitted together, so as to facilitate the installation of the comb plate 12 and the wiper blade 13 in the original wiper blade mounting space. Meanwhile, the close fit between the comb plate 12 and the wiper blade 13 can improve the structural stability of the overall sheet metal parts, enhance the strength of the comb plate 12 and the wiper blade 13, and reduce the vibration and noise of the comb plate 12 and the wiper blade 13 during operation.

[0056] In one feasible implementation, the angle α4 between the straight line L1 containing the extension direction of the wiper blade extension 133 and the reference line L2 is an acute angle. The reference line L2 is a horizontal line passing through the center of the first circle ⊙1 (i.e., the center point a of the roller brush 11), and the point where the wiper blade extension 133 intersects the first circle ⊙1 is located on the upper half of the arc of the first circle ⊙1. This design enhances the squeezing effect of the wiper end 131 on the bristles, helping to remove wastewater and impurities collected by the bristles.

[0057] Furthermore, to prevent the comb tooth end 121 from interfering with the wiping function of the wiping end 131, the distance d1 between the plane M1 containing the end face of the comb tooth end 121 and the plane M2 containing the end face of the wiping end 131 needs to be set. Laboratory comparative studies have shown that the distance d1 can be set between 0mm and 1.1mm, meaning that plane M2 is flush with plane M1, or plane M2 protrudes from plane M1. Preferably, the distance d1 is set between 0.55mm and 1.1mm. This structure ensures that the comb tooth end 121 does not affect the normal wiping function of the wiping end 131, while also achieving the effects of removing water and cutting hair. Preferably, d1 is 0.59mm.

[0058] Since the interference fit between the squeegee end 131 and the bristles significantly affects the squeegee effect of the squeegee 13, and the interference fit between the comb tooth end 121 and the bristles significantly affects the hair-cutting effect of the comb tooth plate 12, precise adjustment and optimization of the interference fits between the squeegee end 131 and the bristles, as well as between the comb tooth end 121 and the bristles, are necessary to ensure that the squeegee 13 and the comb tooth plate 12 can achieve optimal performance. Laboratory comparative studies have shown that when the diameter of the roller brush 11 is 52 mm, the interference fit between the comb tooth end 121 and the bristles can be set between 0.5 mm and 1.5 mm, while the interference fit between the squeegee end 131 and the bristles can be set between 1 mm and 2 mm. Preferably, when the diameter of the roller brush 11 is 52 mm, the interference fit between the comb tooth end 121 and the bristles is 1 mm, and the interference fit between the squeegee end 131 and the bristles is 1.5 mm.

[0059] In this application, since the comb plate 12 is fixed below the wiper blade 13 and there is a mechanical connection between the comb plate 12 and the wiper blade 13, the displacement between the comb plate 12 and the wiper blade 13 is synchronous. Therefore, the comb plate 12 can be used to limit the extreme position of the downward movement of the wiper blade 13.

[0060] In one feasible implementation, the cleaning assembly further includes a support assembly. For example... Figure 4 As shown, the support assembly is located below the comb plate 12. The support assembly can be a rubber-coated assembly, which includes a support base 31 and a limiting rib 32. The limiting rib 32 is fixed to the support base 31. The limiting rib 32 is an elastic element with a certain elastic deformation capability. The limiting rib 32 can be made of natural rubber or synthetic rubber. The lower surface of the comb plate body 122 abuts against the support base 31, and the lower surface of the comb plate extension 123 abuts against the limiting rib 32. By setting the elastic deformation parameters (such as Young's modulus, yield strength, elastic limit, etc.) of the limiting rib 32, the limit position of the downward movement of the comb plate 12 can be predicted, thereby limiting the limit position of the downward movement of the comb plate 12. In this way, the limit position of the downward movement of the wiper blade 13 can be limited by the comb plate 12.

[0061] In practical applications, the roller brush 11 can rotate counterclockwise. Figure 3 (View angle), thereby utilizing the wiper blade 13 to perform self-cleaning, fluffing, and other operations. At this time, the comb plate 12 and the wiper blade 13 will be subjected to resistance in the opposite direction to the counterclockwise rotation of the roller brush 11. The direction of this resistance is generally downward, while the elastic deformation capability of the limiting rib 32 can continuously apply an upward force to the comb plate 12. These two forces cancel each other out, which can keep the comb plate 12 and the wiper blade 13 in their original positions as much as possible, ensuring that the wiper blade 13 always has good wiping ability.

[0062] Optionally, the contact point between the comb plate body 122 and the support base 31, the contact point between the comb plate extension 123 and the limiting rib 32, and the connection point between the comb end 121 and the comb plate extension 123 are not on a straight line. This design can form a triangular-like structure, creating a more stable support system that can maintain the comb plate 12 and the wiper 13 in their set positions as much as possible when the roller brush 11 rotates. Simultaneously, the non-linear arrangement of points reduces the concentrated transmission of force along a single straight line, helping to reduce vibration and noise during the operation of the comb plate 12.

[0063] Laboratory comparative studies have shown that when the first included angle α1 ranges from 120 to 170 degrees, the elastic response of the comb plate 12 is more sensitive, and the vibration and noise during operation are less pronounced. Preferably, the first included angle α1 is 160 degrees. Similarly, laboratory comparative studies have shown that when the second included angle α2 ranges from 90 to 110 degrees, even when the comb plate 12 deflects to its maximum angle, the plane M1 containing the end face of the comb teeth 121 (i.e., the extension direction of the comb teeth 1212) can still remain tangent to the first circle ⊙1, thereby maintaining the comb plate 12's combing and guiding effect on the hair. Preferably, the second included angle α2 is 95 degrees.

[0064] As mentioned above, in practical applications, the roller brush 11 rotates clockwise ( Figure 3 (View) to clean the ground, roller brush 11 rotates counterclockwise ( Figure 3 (From a certain perspective) the wiper blade 13 is used for self-cleaning and fluffing operations such as brush cleaning. To improve the efficiency of the wiper blade 13 in self-cleaning and fluffing the bristles of the roller brush 11, while also considering the service life of the roller brush 11, in one feasible embodiment, the wiper end 131 can be constructed such that the upper surface of the wiper end 131 is a right angle and the lower surface of the wiper end 131 is rounded. When the roller brush 11 rotates counterclockwise to perform self-cleaning and fluffing operations, the bristles on the roller brush 11 will first contact the upper surface of the wiper end 131. Therefore, constructing the upper surface of the wiper end 131 as a right angle structure can improve the self-cleaning efficiency of the wiper end 131 on the roller brush 11. When the roller brush 11 rotates clockwise to clean the floor, the bristles on the roller brush 11 will first contact the lower surface of the squeegee end 131. Therefore, the lower surface of the squeegee end 131 is constructed with rounded corners to reduce wear on the bristles, thereby extending the service life of the roller brush 11. Since the time for the roller brush 11 to rotate clockwise is much longer than the time for it to rotate counterclockwise, the above-mentioned structure of the squeegee end 131 can both improve the self-cleaning efficiency of the roller brush 11 and also effectively ensure the service life of the roller brush 11.

[0065] Preferably, the radius R1 of the fillet on the lower surface of the wiper end 131 is 0.6 mm.

[0066] In one feasible embodiment, the cleaning device further includes a fluid distributor 2, which is positioned close to the roller brush 11, with the suction port located near the fluid distributor 2. Multiple water outlets 21 are evenly distributed along the length of the fluid distributor 2, allowing it to spray cleaning media onto the roller brush 11. When the roller brush 11 cleans the surface to be cleaned, the cleaning media adhering to its bristles softens the dirt, thus helping the roller brush 11 pick up dirt more effectively. Furthermore, the positional relationship between the fluid distributor 2 and the roller brush 11 is configured such that the fluid distributor 2 is located outside the roller brush 11, and the length of the fluid distributor 2 is parallel to the axial direction of the roller brush 11, with the length of the fluid distributor 2 being substantially equal to or greater than the axial length of the roller brush 11. This structure allows the fluid distributor 2 to evenly spray cleaning media along the entire length of the roller brush 11, ensuring that the entire roller brush surface is covered with cleaning media, thereby improving the cleaning effect of the roller brush 11. It should be noted that the fluid distributor 2 can be designed as a floating structure to accommodate roller brushes of different diameters (for example, the diameter of the roller brush will become smaller when it wears down), thereby ensuring that the cleaning medium can be sprayed evenly in the entire axial direction of the roller brush.

[0067] The scraper assembly is fixedly mounted on the fluid distributor 2, and the vertical position of the scraper assembly and the fluid distributor 2 is related to the rotation direction of the roller brush 11. Specifically, when the roller brush 11 rotates in a first direction, it passes the scraper assembly first and then the fluid distributor 2 along its rotation path. Taking a clockwise rotation direction as an example, the scraper assembly is located below the fluid distributor 2. Furthermore, the scraper assembly and the fluid distributor 2 as a whole can move relative to the roller brush 11 so that the scraper assembly always maintains an interference contact with the roller brush 11.

[0068] In one feasible implementation, the scraper assembly includes a comb-tooth plate 12 and a scraper blade 13, wherein the scraper blade 13 is connected to the bottom of the fluid distributor 2 and is fixed in position by the fluid distributor 2. For example, the scraper blade 13 can be bolted to the bottom of the fluid distributor 2, fixed to the bottom of the fluid distributor 2 by a plug-in structure, or the scraper blade 13 can be integrally formed into the bottom of the fluid distributor 2. The scraper blade 13, positioned at the bottom of the fluid distributor 2, can fully utilize the space below the fluid distributor 2, reducing the overall size of the machine, and can more effectively scrape away wastewater and impurities collected by the bristles of the roller brush 11, reducing the time wastewater stays on the ground and improving cleaning efficiency. Furthermore, the squeegee 13 extends along the length of the fluid distributor 2, such that the length of the squeegee 13 is parallel to the axial direction of the roller brush 11, and the length of the squeegee 13 is substantially equal to or greater than the axial length of the roller brush 11. The squeegee end 131 of the squeegee 13 is in interference contact with the bristles of the roller brush 11, that is, the squeegee end 131 extends at least partially into the bristles. This structure ensures that the squeegee 13 covers the entire cleaning area of ​​the roller brush 11, and allows the wastewater collected by the bristles to be guided along the length of the squeegee 13 to quickly collect the wastewater on the entire cleaning area of ​​the roller brush 11, thereby reducing the residue of wastewater on the surface to be cleaned.

[0069] In practical applications, with the surface to be cleaned as a reference, the rotating roller brush 11 exerts an upward or downward force on the squeegee 13. This force pushes the squeegee 13 up and down, causing the squeegee tip 131 to either lose contact with the bristles or extend excessively into the bristles. If the squeegee tip 131 loses contact with the bristles, the squeegee 13 will be unable to remove wastewater from the bristles, while if the squeegee tip 131 extends excessively into the bristles, it will cause excessive wear on the bristles and may even affect the normal rotation of the roller brush 11. To solve these problems, the vertical movement range of the squeegee 13 needs to be limited.

[0070] In this embodiment, the wiping end 131 of the wiper blade 13 is located below the water outlet end 21 of the fluid distributor 2, and is as close as possible to the water outlet end 21 without affecting the spraying of liquid at the water outlet end 21, so as to make the structure of the cleaning equipment more compact, and the fluid distributor 2 is used to limit the movement range of the wiper blade 13. Since the wiper blade 13 is mechanically connected to the fluid distributor 2, the wiper blade 13 cannot move independently of the fluid distributor 2, and the movement range of the wiper blade 13 is limited by the fluid distributor 2. Specifically, when the fluid distributor 2 is a floating structure, the wiper blade 13 can move with the fluid distributor 2. The limit position of the wiper blade 13 moving upward or toward the roller brush 11 is limited by the limit position of the fluid distributor 2 moving upward or toward the roller brush 11, and the limit position of the wiper blade 13 moving downward or away from the roller brush 11 is also limited by the limit position of the fluid distributor 2 moving downward or away from the roller brush 11. When the fluid distributor 2 is a fixed structure, since the fluid distributor 2 cannot move, the wiper blade 13 can basically not move except for its own elastic deformation. At the same time, since the suction port is located near the fluid distributor 2, the wiper end 131 is as close as possible to the water outlet end 21, which also helps the suction motor to quickly suck the sewage scraped by the wiper end 131 into the suction port. The roller brush 11, after the dirt is scraped off, can be immediately wetted by clean cleaning medium, preparing for the next time to wipe the floor and pick up the dirt.

[0071] It should be noted that, since space needs to be reserved below the fluid distributor 2 to accommodate the wiper blade 13 and the comb plate 12, this space means that there is undesigned floating space below the floating fluid distributor 2. This space may move excessively downwards under the influence of the wiper blade 13 and / or the comb plate 12, causing the floating fluid distributor 2 to be unable to effectively limit the downward movement of the wiper blade 13. To solve this problem, the support base 31 and the limiting rib 32 can be used to limit the downward movement of the wiper blade 13. For details on this, please refer to the aforementioned embodiments; further explanation is not provided here.

[0072] To simplify the assembly process of the comb plate 12 and the wiper plate 13, in one feasible embodiment, the comb plate body 122 is provided with at least one countersunk hole 1221 and at least one alignment hole 1222, and the wiper plate body 132 is provided with a mounting hole 1321 and a positioning hole 1322, so that when the comb plate body 122 and the wiper plate body 132 are fitted together, the countersunk hole 1221 is exactly aligned with the mounting hole 1321, and the alignment hole 1222 is exactly aligned with the positioning hole 1322.

[0073] The fluid distributor 2 has a number of screw holes (not shown) at its bottom. When the wiper blade 13 and the comb plate 12 need to be installed at the bottom of the fluid distributor 2, the operator can pass the countersunk bolt through the countersunk hole 1221, the mounting hole 1321 and the screw hole in sequence, and then tighten the countersunk bolt to fix the comb plate 12 and the wiper blade 13 to the fluid distributor 2. Furthermore, the fluid distributor 2 also has at least one positioning post (not shown) at its bottom. When the wiper blade 13 and the comb plate 12 need to be installed at the bottom of the fluid distributor 2, the operator can first insert the positioning post into the positioning hole 1322 and the alignment hole 1222 in sequence to align the comb plate 12 and the wiper blade 13, so that the countersunk bolt can be passed through the countersunk hole 1221, the mounting hole 1321 and the screw hole in sequence. In addition, since the wastewater scraped off by the wiper blade 13 flows through the comb plate 12, in order to increase the rigidity of the parts and reduce the mating clearance, and to prevent dirty water from remaining in the gap between the wiper blade 13 and the comb plate 13, the comb plate 12 and the wiper blade 13 are welded together.

[0074] For the parameters of the comb plate 12, the wiper plate 13, and the comb teeth 1212, please refer to the results in Tables 1 and 2. Tables 1 and 2 are tables generated after Design of Experiments (DOE).

[0075] Table 1 (Anti-tangling effect comparison table)

[0076]

[0077]

[0078] Table 2 (Analysis of Comb Tooth Parameters)

[0079]

[0080]

[0081] Laboratory tests showed that dry hair is more likely to get tangled on the roller brush 11. When the thickness of the comb plate 12 is 1.5mm-0.6mm and the length of the comb teeth 1212 is 1.5mm-3mm, the anti-tangling effect is better, with no more than 3-5 hairs getting tangled. When the thickness of the comb plate 12 is less than or equal to 1mm and the length of the comb teeth 1212 is 2mm, the anti-tangling effect is the best, with almost no tangling. The preferred parameter combination of the comb plate 12, wiper blade 13, and comb teeth 1212 is as follows: the thickness of the wiper blade 13 ranges from 0.6 mm to 2 mm, the thickness of the comb plate 12 ranges from 0.5 mm to 1.5 mm, the root width d2 of the comb teeth 1212 ranges from 1 mm to 3 mm, the tip width d3 of the comb teeth 1212 ranges from 0.5 mm to 2 mm, the length d4 of the comb teeth 1212 ranges from 1.3 mm to 3 mm, the gap d5 between two adjacent comb teeth 1212 ranges from 1 mm to 3 mm, and the number of comb teeth 1212 ranges from 42 to 84.

[0082] Preferably, the wiper blade 13 is made of metal and has a thickness of 1 mm.

[0083] In practical applications, the length and thickness of the comb teeth 1212 are crucial factors affecting the combing effect. When the extension direction of the comb teeth 1212 is tangential to the roller brush 11, if the comb teeth 1212 are too long, the hair will become entangled on them, hindering the removal of hair from between the teeth. If the comb teeth 1212 are too short, the combing effect will be reduced. If the thickness of the comb teeth 1212 is too great, the combing effect will be reduced, while if the thickness is too small, the comb teeth 1212 are prone to breakage.

[0084] Preferably, the comb plate 12 is made of metal, the thickness of the comb plate 12 (i.e. the comb tooth 1212) is 0.6 mm, the root width d2 of the comb tooth 1212 is 2 mm, the tip width d3 of the comb tooth 1212 is 1 mm, and the length d4 of the comb tooth 1212 is 2 mm.

[0085] Preferably, when the number of comb teeth 1212 is 42, the gap d5 between two adjacent comb teeth 1212 is 3mm, and when the number of comb teeth 1212 is 84, the gap d5 between two adjacent comb teeth 1212 is 1mm. This design can avoid wasting space due to excessively large gaps between teeth, and also avoid hindering the passage of hair due to excessively small gaps between teeth.

[0086] Preferably, the comb teeth 1212 are trapezoidal teeth, that is, the shape of the comb teeth 1212 from the tooth tip to the tooth root is trapezoidal, the length d4 of the comb teeth 1212 is the extension height from the tooth tip to the tooth root, and the gap d5 between two adjacent comb teeth 1212 is the gap between the tooth roots of two adjacent comb teeth 1212. Specifically, in this embodiment, the length from the tooth tip of the comb tooth 1212 to the outer extension 123 of the comb plate is the length of the comb tooth 1212.

[0087] The slot 1211 includes the gap between the two comb teeth and the extension portion. The extension portion of the slot 1211 extends from the root of the comb tooth 1212 (i.e. the end of the comb tooth plate extension 123) toward the comb tooth plate extension 123. The depth d6 of the slot 1211 extending into the comb tooth plate extension 123 is 1 mm.

[0088] Based on the same concept, this application also provides a floor scrubbing machine, which includes a body system, a cleaning system, a fluid supply system, a dirt recovery system, and an energy system.

[0089] The machine system consists of a handle 3, a body 4, and a floor brush 5. The body 4 is typically designed to be upright, and the handle 3 is mounted on the body 4 for a comfortable grip during cleaning. The handle 3 usually contains control buttons or switches used to start the machine, adjust cleaning power, or control other functions of the floor scrubber. The floor brush 5 is the part that directly contacts the floor, tile, or other surfaces to be cleaned, and it is rotatably connected to the body 4. Under the operator's control, the floor brush 5 can move freely on the surface to be cleaned. Simultaneously, the operator can control the direction of movement and working status of the floor brush 5 by holding the handle 3, and switch the floor scrubber between upright and tilted positions to adapt to different cleaning needs.

[0090] The cleaning system includes a cleaning component and a drive motor. The cleaning component is typically housed in the floor brush 5 and includes one or more rotating roller brushes 11. These roller brushes 11 rotate under the drive motor to pick up dirt from the surface to be cleaned. The bristles of the roller brushes 11 are typically made of materials such as cloth, nylon, polypropylene, or metal wire. The operator can choose different types of roller brushes according to different cleaning needs. For example, cloth roller brushes are suitable for cleaning smooth floors, while nylon roller brushes are suitable for cleaning rough floors or floors with stubborn stains. When cleaning tile floors, the operator can use a cloth roller brush; when cleaning cement floors, the operator can use a nylon roller brush.

[0091] The fluid supply system consists of a clean water tank, a water pump, and a fluid distributor 2. The clean water tank stores clean water or water with added detergent, providing the necessary liquid for the cleaning process. The water pump draws cleaning media from the clean water tank and delivers it to the fluid distributor 2 through pipes. The fluid distributor 2 is responsible for evenly spraying the cleaning media onto the roller brush 11 or the surface to be cleaned, softening the dirt and thus helping the roller brush 11 pick up dirt more effectively.

[0092] The dirt recovery system consists of a wastewater tank, a recovery channel, a suction port, and a suction motor. The suction port, located near the roller brush 11, is connected to the suction motor and is responsible for sucking up the dirt picked up by the roller brush 11. The suction motor generates strong suction to lift the dirt from the ground and send it through the recovery channel into the wastewater tank. The recovery channel connects the suction port and the wastewater tank, used to transfer dirt from the ground to the wastewater tank. The wastewater tank stores dirty water and grime collected during the cleaning process.

[0093] The energy system typically includes a rechargeable battery, such as a lithium-ion battery or a nickel-cadmium battery, which provides the necessary power to the water pump, suction motor, and drive motor, allowing the floor scrubber to operate without the constraints of a power cord and ensuring that it can efficiently complete cleaning tasks in environments far from electrical outlets.

[0094] When the floor scrubber is in operation, the operator can control the machine body 4 and floor brush 5 via handle 3, allowing it to contact the surface to be cleaned in an upright or tilted position. The machine body 4 contains a rechargeable battery that powers the entire machine, while the roller brush 11 in the floor brush 5 directly contacts the ground, picking up dirt by rotating. Cleaning media in the clean water tank is pumped to the fluid distributor 2 and then evenly sprayed onto the roller brush 11 or the surface to be cleaned. Simultaneously, the dirt recovery system activates; the suction motor generates suction, drawing in the dirt picked up by the roller brush 11 through the suction port and transporting it to the wastewater tank through the recovery channel.

[0095] The following section will explain in detail the working principle of the comb plate and squeegee, using a floor scrubber as an example, in a specific application scenario.

[0096] Application Scenario 1

[0097] Ms. C owns a pet cat, and she often finds cat hair and her own long hair on the floor. Cleaning this long hair manually is very troublesome. Therefore, Ms. C bought a floor scrubber. However, after using it for a while, she found that the long hair easily got tangled in the scrubber's roller brush. The hair tangled in the brush not only hinders the brush's contact with the floor, reducing its cleaning effectiveness, but also causes the hair to become knotted with the bristles, making it very difficult to remove.

[0098] To solve the problem of hair tangling in the roller brush, Ms. C purchased a new floor scrubber with a hair-cutting function. This scrubber features a comb plate added below the squeegee. The comb plate fits tightly against the squeegee, and the comb teeth make interference contact with the bristles on the roller brush. These comb teeth have multiple serrated edges. When the roller brush rotates, these serrated teeth cut the long hairs tangled in the bristles into shorter hairs and comb them off the brush. Simultaneously, the regular arrangement of the comb teeth helps to organize and orient the short hairs and bristles. Then, under the suction of the motor, the organized short hairs are quickly sucked into the suction port through the gaps between the comb teeth.

[0099] Because this floor scrubber retains the squeegee, and both the squeegee and comb have been thinned, the overall structure remains largely unchanged. The squeegee and comb are still installed in the same positions as the old squeegee. Compared to the old scrubber, the new scrubber's squeegee function is unaffected. Utilizing the squeegee's wiping function, very little water residue remains on the floor after cleaning. While retaining the functionality and performance of the old scrubber, this new scrubber features an anti-hair tangling function on the roller brush, effectively solving the problem of users needing to clean hair off the roller brush after use.

[0100] Therefore, the technical solution provided in this application includes a cleaning device comprising a fluid distributor, a roller brush, a comb plate, and a squeegee. The fluid distributor is located on the outside of the roller brush and can spray cleaning medium onto the roller brush to improve its cleaning effect. The squeegee is fixed below the fluid distributor, and the comb plate is fixed below the squeegee. The squeegee can be fixed in position using the fluid distributor, while the comb plate uses the squeegee as a support structure, thus providing a stable mounting platform for the comb plate. The above structure can fully utilize the space below the fluid distributor to place the squeegee and comb plate, without requiring additional space for the comb plate or altering the original structure of the cleaning device, ensuring compatibility and operational consistency with existing products. Both the squeegee and the comb plate make interference contact with the bristles of the roller brush. When the roller brush rotates, the comb plate first uses its teeth to cut and separate the long hairs entangled on the roller brush, and then the squeegee squeezes the bristles to scrape away impurities, sewage, and other dirt mixed in with the bristles. Meanwhile, the comb teeth can also straighten and organize the bristles, facilitating the subsequent squeegee operation. This application, through the coordinated work of the comb teeth and squeegee, can reduce the entanglement of long hair in the roller brush and further improve the cleaning efficiency of the roller brush.

[0101] The above description is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
