Description

Technical Field

[0001] The present application relates to the field of cleaning equipment, and in particular to a cleaning equipment. Background Art

[0002] With the continuous advancement of technology and the growing demand of consumers, floor scrubbers are becoming more and more widely used. The core component of a floor scrubber is the roller brush, which rotates at high speed during operation to remove dirt and impurities from the floor through physical contact and friction.

[0003] However, current floor scrubbers on the market generally have the problem of hair entanglement on their roller brushes, failing to effectively prevent hair from getting tangled in them. To address this issue, some products use plastic bristles, but these materials are less effective in preventing entanglement with longer hair. Utility Model Content

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

[0005] To achieve the above-mentioned purpose, the present application provides a cleaning device on the one hand, which includes at least a cleaning component, and the cleaning component includes a roller brush and a scraper component, wherein the scraper component includes a comb plate and a wiper plate, and the comb plate and the wiper plate are both in contact with the roller brush, and the wiper plate is used to scrape dirt off the roller brush; when the roller brush rotates in a first direction, the roller brush first passes through the comb plate and then passes through the wiper plate; the comb plate includes a comb tooth end, and the comb tooth end extends in a direction away from the wiper plate; the end of the wiper plate is provided with a wiper end; the thickness of the wiper end is greater than the thickness of the comb tooth end.

[0006] It can be seen that the technical solution provided by the present application is that the cleaning equipment is provided with a roller brush, a comb plate and a wiper. The wiper and comb plate are both in interference contact with the bristles on the roller brush, and the wiper is used to scrape dirt off the roller brush. There is an upper and lower positional relationship between the wiper and comb plate to ensure that when the roller brush rotates in a first direction, the roller brush can first pass through the comb plate and then pass through the wiper. In this way, the comb plate can first use the comb teeth to cut the long hair entangled on the roller brush and separate the hair. The wiper then squeezes the bristles to scrape off impurities, sewage and other dirt mixed in the bristles. At the same time, the comb teeth can also comb and organize the bristles to facilitate the subsequent wiping operation of the wiper. Through the coordinated work of the comb plate and the wiper, the present application can not only reduce the entanglement of long hair on the roller brush, but also further improve the cleaning efficiency of the roller brush.

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

[0022] Furthermore, the terms "installed," "disposed," "provided with," "connected," "slidingly connected," "fixed," and "socketed" should be interpreted broadly. For example, "connected" can mean a fixed connection, a removable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be a direct connection, an indirect connection through an intermediary, or internal communication between two devices, elements, or components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

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

[0024] The roller brush is the rotating part of a floor scrubber that contacts and cleans the floor. It is a core component of the machine. The roller brush rotates at high speed during operation, removing dirt and impurities from the floor through physical contact and friction. However, existing floor scrubbers commonly suffer from brush entanglement. As the roller brush rotates, it is easily entangled by hair and other slender objects. This entangled hair hinders contact between the roller brush and the floor, reducing friction between the roller brush and the floor, thereby reducing the cleaning effectiveness of the roller brush. Furthermore, entangled hair causes uneven force on the roller brush, accelerating wear and shortening its service life.

[0025] To address the issue of hair entanglement on roller brushes, some manufacturers use plastic materials such as polyester and nylon to make the bristles on roller brushes. Because plastic bristles typically have a smooth surface, short hairs are less likely to adhere to or become entangled in them. However, plastic bristles have poor water absorption, which results in the bristles being unable to effectively absorb and retain moisture in wet or humid cleaning environments. This easily leaves water stains on the floor after cleaning, reducing the cleaning effectiveness of the roller brush. Furthermore, because plastic materials are prone to static electricity, long hair or a large amount of hair is more likely to become entangled in the bristles.

[0026] Therefore, how to improve the structure of the floor scrubber 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 solved in this field.

[0027] In response to the above problems, the present application provides a cleaning device, and the specific type of the cleaning device can be a floor scrubber, a sweeping robot, or other device with a roller brush. To facilitate understanding of the solution of the present application, the structure and working principle of the cleaning device are briefly described using a floor scrubber as an example. Figure 1 、 Figure 2 and Figure 3 As shown in the figure, the floor scrubber is mainly composed of a body system, a cleaning system, a fluid supply system, a dirt recovery system and an energy system.

[0028] The body system consists of a handle 3, a body 4 and a floor brush 5, wherein the body 4 is usually designed to be upright, and the handle 3 is set on the body 4 so that the operator can maintain a comfortable grip when cleaning. The handle 3 usually contains some control buttons or switches, which are used to start the machine, adjust the cleaning power or control other functions of the floor scrubber. The floor brush 5 is the part that directly contacts the floor or tile to be cleaned, and the floor brush 5 is rotatably connected to the body 4. Under the operation of the operator, the floor brush 5 can move freely on the surface to be cleaned. At the same time, the operator can also control the movement direction and working state of the floor brush 5 by holding the handle 3, and control the floor scrubber to switch between an upright state and an inclined state to adapt to different cleaning needs.

[0029] The cleaning system includes a cleaning component and a drive motor. The cleaning component is usually set in the floor brush 5, which includes one or more rotating roller brushes 11. The roller brush 11 rotates under the drive of the drive motor to pick up dirt on the surface to be cleaned. The bristles of the roller brush 11 are usually made of flannel, nylon, polypropylene or metal wire, etc. The operator can choose different types of roller brushes according to different cleaning needs. For example, a flannel roller brush is suitable for cleaning smooth floors, while a nylon roller brush is suitable for cleaning rough floors or floors with stubborn stains. When the operator needs to clean a tile floor, he can choose a flannel roller brush, and when the operator needs to clean a cement floor, he can choose 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 detergent added, providing the necessary liquid for the cleaning process. The water pump draws cleaning medium from the clean water tank and delivers it to the fluid distributor 2 via a pipe. The fluid distributor 2 evenly sprays the cleaning medium onto the roller brush 11 or the surface to be cleaned, softening the dirt and helping the roller brush 11 to pick up the dirt more effectively.

[0031] The dirt recovery system consists of a sewage tank, a recovery channel, a sewage suction port and a suction motor. The sewage suction port is located near the roller brush 11 and is connected to the suction motor, which is responsible for sucking in the dirt picked up by the roller brush 11. The suction motor is used to generate a strong suction force to suck the dirt from the ground and send it into the sewage tank through the recovery channel. Specifically, a floor scraper 51 is provided at the bottom of the floor brush 5. The floor scraper 51 is used to contact the surface to be cleaned. The floor scraper 51 is parallel to the axis of the roller brush 11. The extension length of the floor scraper 51 is basically the same as the length of the roller brush 11. When the floor scrubber is performing the 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 sewage suction port is located in this area. The wet roller brush 11 wipes the ground and picks up the dirt on the ground. As the roller brush 11 rotates, the dirt on the roller brush 11 is scraped off by the scraping strip set in area A (in some scenarios, the centrifugal force generated by the high-speed rotation of the roller brush 11 can also be used to separate the dirt from the roller brush 11). The scraping strip is located above the sewage suction port, so that the scraped dirt and other solid-liquid mixtures are immediately sucked into the sewage suction port. The recovery channel connects the sewage suction port and the sewage tank to transfer the dirt from the ground to the sewage tank. The sewage tank is used to store dirty water and dirt picked up during the cleaning process.

[0032] The energy system usually includes a rechargeable battery, such as a lithium-ion battery or a nickel-cadmium battery, which can provide the necessary power for the water pump, suction motor and drive motor, so that the floor scrubber can be freed from the constraints of wires and ensure that the floor scrubber can efficiently complete the cleaning task in an environment away from the socket.

[0033] When the floor scrubber is working, the operator can control the body 4 and floor brush 5 of the floor scrubber through the handle 3, so that it can contact the surface to be cleaned in an upright or tilted state. A rechargeable battery is installed inside the body 4 to provide power for the entire machine, while the roller brush 11 in the floor brush 5 is in direct contact with the ground, and the roller brush 11 picks up dirt by rotating. The cleaning medium in the clean water tank is transported to the fluid distributor 2 through the water pump, and then evenly sprayed onto the roller brush 11 or the surface to be cleaned. At the same time, the dirt recovery system starts working, the suction motor generates suction, sucks in the dirt picked up by the roller brush 11 through the suction port, and transports it to the sewage tank through the recovery channel.

[0034] Please refer to Figures 3 to 13In one possible embodiment, the cleaning device includes at least a cleaning assembly, which includes a roller brush 11 and a scraper assembly, wherein the scraper assembly is composed of a comb plate 12 and a wiper 13. The comb plate 12 and the wiper 13 both extend in a direction parallel to the axial direction of the roller brush 11, and the comb plate 12 and the wiper 13 are in contact with the roller brush 11 along the entire axial direction.

[0035] The comb plate 12 and the wiper plate 13 are arranged adjacent to each other, and the vertical positional relationship between the comb plate 12 and the wiper plate 13 is related to the rotation direction of the roller brush 11. Specifically, when the roller brush 11 rotates in the first direction, the roller brush 11 first passes through the comb plate 12 and then passes through the wiper plate 13 on the rotation path of the roller brush 11. For example, Figure 3 The perspective shown is for reference only. If the first rotation direction of the roller brush 11 is clockwise, the comb plate 12 is located below the wiper blade 13 to ensure that when the roller brush 11 rotates clockwise, the roller brush 11 passes the comb plate 12 before passing the wiper blade 13. If the first rotation direction of the roller brush 11 is counterclockwise, the comb plate 12 is located above the wiper blade 13 to ensure that when the roller brush 11 rotates counterclockwise, the roller brush 11 passes the comb plate 12 before passing the wiper blade 13. This application uses the clockwise first rotation direction as an example for description. Accordingly, the comb plate 12 is located below the wiper blade 13.

[0036] The wiper blade 13 has a wiper end 131 at its end, which is in interference contact 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 becoming entangled in the roller brush 11, the present application utilizes a comb plate 12 to cut and comb the hair on the roller brush 11. The comb plate 12 can be fixed to the bottom of the wiper blade 13 using bolts or rivets. The comb plate 12 has a comb end 121 at its end, which extends away from the wiper blade 13. The comb end 121 is in interference contact with the bristles of the roller brush 11, that is, the comb 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 entangled in the roller brush 11. Because the wiper blade 13 is in interference contact with the roller brush 11 along its entire axial length, if the wiper blade 13 is too thin, the rotational force of the roller brush 11 will cause the wiper blade 13 to vibrate. This will prevent the wiper blade 13 from maintaining stable interference contact with the bristles of the roller brush 11 along its entire axial length, and may cause false contact points at certain contact points, ultimately affecting the wiping effect of the wiper blade 13. However, if the wiper blade 13 is too thick, the wiper blade 13 will apply excessive pressure to the roller brush 11 during rotation, affecting the speed of the roller brush 11 and potentially causing the drive motor of the roller brush 11 to overheat, affecting the overall performance of the machine. Similarly, if the comb plate 12 is too thick, the combing effect will be affected. If the thickness of the comb plate 12 is too small, the comb plate 12 may break due to insufficient strength when in contact with the rotating roller brush 11. Therefore, considering the scraping effect and combing effect, the thickness of the wiper end 131 is designed to be greater than the thickness of the comb 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 1.3mm to 3mm, and the thickness of the comb teeth 1212 is 0.5mm to 1.5mm. The shape of the comb teeth 1212 can be constructed as trapezoidal teeth or square teeth. When the roller brush 11 rotates, the serrated comb teeth can cut and pull the long hair entangled in the bristles into short hair, and comb the cut short hair off the bristles. At the same time, the regular arrangement design of the comb teeth 1212 can also organize and orient the short hair and the bristles. After that, under the suction of the suction motor, the organized short hair and the unbroken long hair will be quickly sucked into the sewage suction port through the gaps between the comb teeth.

[0039] It should be noted that the interference fit between the comb end 121 and the bristles is smaller than that between the wiper end 131 and the bristles. The shorter reach of the comb end 121 reduces excessive pull on the bristles, helping to protect the bristles and extend their lifespan. The longer reach of the wiper end 131 allows for deeper contact with the bristles, helping to collect and recover dirt and moisture at a deeper level.

[0040] It's important to note that, given that many cleaning equipment are equipped with a wiper, to fully utilize the existing wiper installation space, the original wiper can be split into two components, the wiper 13 and the comb plate 12, based on the original wiper structure. Both the wiper 13 and the comb plate 12 are sheet metal components, and the wiper 13 is thinner than the original wiper, ensuring that when the comb plate 12 and the wiper 13 are attached together, the total sheet metal thickness is the same as the original wiper. This allows the comb plate 12 and the wiper 13 to be installed in the original wiper installation space without changing the original wiper installation space, maintaining compatibility with the original equipment. The close installation of the comb plate 12 and the wiper 13 also helps maintain overall strength. Furthermore, the wiper 13 is positioned above the comb plate 12. Working in conjunction with the comb plate 12, the wiper 13 and the comb plate 12 provide additional anti-tangling capabilities while maintaining the original wiper performance. The comb plate 12 and the wiper plate 13 can be made of metal materials such as aluminum and stainless steel to give them both toughness and durability. The thickness of the wiper plate 13 and the thickness of the comb plate 12 will be described in detail later.

[0041] like Figure 3 As shown, in actual application, the roller brush 11 is usually set at the front end of the floor brush 5 to improve cleaning efficiency and optimize the cleaning path, while the recovery channel and the sewage suction port are set in the middle of the floor brush 5, behind the roller brush 11, to facilitate the arrangement of various recovery pipes. Under this structure, the roller brush 11 needs to rotate clockwise (to Figure 3 The perspective shown is for reference only. The roller brush 11 first passes through the wiper 13 and then through the water outlet end 21 of the fluid distributor 2, thereby sweeping up the dirt from the ground and pushing it to the middle of the floor brush 5, so as to facilitate the dirt recovery system to recover dirt and sewage.

[0042] In this embodiment, because the comb plate 12 is positioned below the wiper blade 13 and the roller brush 11 rotates clockwise, the comb end 121 is designed to extend away from the wiper blade 13. This allows the serrated comb edge to face in the opposite direction of rotation of the roller brush 11. As the roller brush 11 rotates, it passes over the comb plate 12 before passing over the wiper blade 13. The comb teeth on the comb end 121 can effectively comb the hairs within the bristles and allow them to be sucked away.

[0043] To ensure that the force applied by the comb-tooth end 121 to the roller brush 11 is evenly distributed, in a feasible embodiment, the contact posture between the comb-tooth end 121 and the roller brush 11 can be designed as follows: the plane M1 where the end face of the comb-tooth end 121 is located is tangent to the first circle ⊙1, wherein 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, wherein 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-tooth end 121 is in interference contact with the bristles of the roller brush 11, it is necessary to ensure that the plane M1 where the end face of the comb-tooth end 121 is located extends into the bristles according to the preset value, that is, the radius of the first circle ⊙1 is smaller than the radius of the second circle ⊙2. It should be pointed out that the fully stretched bristles on the roller brush 11 can be understood as the state in which the roller brush 11 has never been wetted since leaving the factory, and therefore the radius of the second circle ⊙2 corresponds to the radius of the roller brush 11 when it has just left the factory.

[0044] After the roller brush 11 has been used for a period of time, the length of the bristles will become shorter due to wear. Compared to the state when it was just shipped from the factory, the distance from the center point a of the roller brush 11 to the outermost edge of the bristles will become smaller. In order to ensure that the comb tooth end 121 can still be in interference contact with the bristles after the roller brush 11 has been used for a period of time, the radius of the first circle ⊙1 can be further limited. Specifically, a circle is made with the distance from the center point a of the roller brush 11 to the outermost edge of the bristles after the roller brush 11 has reached half of its service life as the radius (for distinction, this circle is recorded as the third circle ⊙3), 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 pointed out that the interference between the plane M1 where the end face of the comb tooth end 121 is located and the bristles will be described in detail later.

[0045] When the plane M1 on which the end surface of the comb-tooth end 121 lies is tangent to the first circle ⊙1, the force applied by the comb-tooth end 121 to the roller brush 11 is evenly distributed along the tangent line. This reduces excessive local pressure from the comb-tooth end 121 on the roller brush 11 and prevents local damage to the bristles. Furthermore, the tangent plane M1 on which the end surface of the comb-tooth end 121 lies and the first circle ⊙1 ensures smooth contact between the comb tooth edges and the bristles, facilitating the comb teeth' ability to comb and guide messy hair.

[0046] In one feasible embodiment, the comb plate 12 includes a comb plate extension 123, and the comb end 121 bends and extends from the comb plate extension 123 away from the wiper blade 13. In other words, the comb end 121 is connected to the end of the comb plate extension 123, and the connection between the comb end 121 and the comb plate extension 123 has a bend structure, which causes the comb end 121 to extend away from the wiper blade 13. For ease of description, this application refers to the connection between the comb end 121 and the comb plate extension 123 as the bend.

[0047] Furthermore, the end surface of the comb-tooth end 121 is provided with a plurality of slots 1211 to form a plurality of 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, and spacing between the slots 1211. Then, the end surface of the comb-tooth end 121 is cut using methods such as laser cutting, die stamping, or tool cutting to form the 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 passes through the material body. A comb tooth 1212 can be formed between two adjacent slots 1211.

[0048] At the same time, to prevent dirt, hair, and other contaminants from accumulating at the bend, the slot 1211 can extend all the way to the bend. With this structure, the bend is also covered by the slot 1211, meaning a gap exists at the junction of the comb tooth end 121 and the comb tooth plate extension 123. Therefore, dirt, hair, and other contaminants at the bend can be quickly drawn into the suction port through the gap.

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

[0050] Since the comb-tooth end 121 is located at the end of the comb-tooth plate extension 123, the connection between the comb-tooth end 121 and the comb-tooth plate extension 123 is the end of the comb-tooth plate extension 123. Obviously, there is a gap at the end of the comb-tooth plate extension 123. With this structure, when the comb-tooth plate 12 and the wiper plate 13 are assembled together, even if the comb-tooth plate extension 123 and the wiper plate extension 133 are tightly fitted together, there will still be a partial gap at the end of the comb-tooth plate extension 123. This means that after the sewage and hair on the roller brush 11 are separated from the bristles, they can be quickly sucked into the sewage suction port through the above-mentioned gap and will not be retained in the bend (i.e., the connection between the comb-tooth end 121 and the comb-tooth plate extension 123). At the same time, since sewage will not be retained in the bend, the water content of the roller brush 11 can also be reduced, allowing the roller brush 11 to maintain a certain degree of dryness, and the roller brush 11 will not increase water stains on the ground when cleaning the ground.

[0051] In one feasible embodiment, the wiper blade 13 includes a wiper blade extension 133. The distal end of the wiper blade extension 133 (i.e., the end of the wiper blade extension 133 closest to the roller brush 11) forms the wiper end 131. Furthermore, the wiper blade extension 133 abuts against the comb plate extension 123, and the slot 1211 extends to abut against the wiper blade extension 133. This ensures that even if the wiper blade extension 133 obstructs the comb plate extension 123, the abutment between the wiper blade extension 133 and the comb plate extension 123 remains intact, allowing wastewater, hair, and other contaminants at the bend to be smoothly drawn into the sewage suction port through the slot 1211.

[0052] Optionally, the comb plate 12 is fitted with the wiper plate 13 , and the thickness of the wiper plate 13 is greater than the thickness of the comb plate 12 .

[0053] In a feasible embodiment, the comb plate 12 includes a comb plate body 122 and a comb plate extension section 123, and the comb tooth end 121 can be set at the end of the comb plate extension section 123. There is a first angle α1 between the extension direction of the comb plate body 122 and the extension direction of the comb plate extension section 123, and there is a second angle α2 between the extension direction of the comb tooth end 121 and the extension direction of the comb plate extension section 123, wherein the degree of the first angle α1 is not equal to the degree of the second angle α2. The existence of the first angle α1 and the second angle α2 can change the stress distribution of the comb plate 12 when it is subjected to force, which helps the comb plate 12 to disperse and absorb force in multiple directions, thereby expanding the elastic response range of the comb plate 12, and ultimately allowing the comb plate 12 to more effectively adapt to forces in different directions, thereby improving its flexibility and efficiency during the combing process. At the same time, the segmented design of the comb plate body 122, the comb plate extension section 123 and the comb end 121 can also realize independent optimization of different parts of the comb plate 12 to better adapt to the narrow installation space under the fluid distributor 2 and ensure that the relevant parameter requirements of the comb end 121 are achieved in the limited installation space.

[0054] It should be noted that the comb plate body 122, the comb plate extension section 123 and the comb tooth end 121 can be manufactured in one piece. For example, a rolling process can be used on a whole piece of strip metal plate to form the comb plate body 122, the comb plate extension section 123 and the comb tooth end 121. For another example, a casting process can be used to manufacture the comb plate body 122, the comb plate extension section 123 and the comb tooth end 121 in one piece. Of course, the comb plate body 122, the comb plate extension section 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 section 133. The end of the wiper blade extension section 133 (i.e., the end of the wiper blade extension section 133 close to the roller brush 11) constitutes the wiper end 131. Furthermore, the angle α3 between the extension direction of the wiper blade body 132 and the extension direction of the wiper blade extension section 133 is the same as the first angle α1, that is, the wiper blade 13 has a shape similar to the comb plate 12. The above structural design can make the wiper blade body 132 fit tightly with the comb plate body 122, and at the same time, can make the wiper blade extension section 133 fit tightly with the comb plate extension section 123, thereby minimizing the total sheet metal thickness after the comb plate 12 and the wiper blade 13 are attached together, so as to facilitate the installation of the comb plate 12 and the wiper blade 13 in the original wiper blade installation space. At the same time, the comb plate 12 and the wiper blade 13 are tightly fitted together, which can also improve the structural stability of the overall sheet metal, 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 when working.

[0056] In one feasible embodiment, the angle α4 between the straight line L1 along which the wiper blade extension 133 extends and the reference line L2 is an acute angle, wherein 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 arc of the first circle ⊙1. This design enhances the squeezing effect of the wiper end 131 on the bristles, helping to scrape away dirty water and impurities collected by the bristles.

[0057] Furthermore, to prevent the comb-tooth end 121 from interfering with the wiping function of the wiper end 131, a distance d1 between the plane M1 on which the end surface of the comb-tooth end 121 lies and the plane M2 on which the end surface of the wiper end 131 lies needs to be set. Laboratory studies have shown that distance d1 can be set between 0 mm and 1.1 mm, meaning that plane M2 is flush with plane M1 or protrudes from plane M1. Preferably, distance d1 is set between 0.55 mm and 1.1 mm. This structure ensures that the comb-tooth end 121 does not interfere with the normal wiping function of the wiper end 131, while ensuring both water removal and hair cutting. Preferably, d1 is 0.59 mm.

[0058] The interference between the wiper end 131 and the bristles has a significant impact on the wiping effect of the wiper blade 13, while the interference between the comb end 121 and the bristles has a significant impact on the hair-cutting effect of the comb plate 12. Therefore, the interference between the wiper end 131 and the bristles, as well as the interference between the comb end 121 and the bristles, need to be precisely adjusted and optimized to ensure that the wiper blade 13 and the comb plate 12 can perform at their best. According to laboratory control studies, when the diameter of the roller brush 11 is 52 mm, the interference between the comb end 121 and the bristles can be set between 0.5 mm and 1.5 mm, while the interference between the wiper 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 between the comb end 121 and the bristles is 1 mm, and the interference between the wiper end 131 and the bristles is 1.5 mm.

[0059] In the present application, since the comb plate 12 is fixed below the wiper 13 and there is a mechanical connection between the comb plate 12 and the wiper 13, the displacement between the comb plate 12 and the wiper 13 is synchronized, so it is possible to consider using the comb plate 12 to limit the extreme position of the downward movement of the wiper 13.

[0060] In a feasible embodiment, the cleaning assembly further comprises a bracket assembly. Figure 4 As shown, the bracket assembly is arranged below the comb plate 12, and the bracket assembly can be a rubber-coated assembly, which includes a support seat 31 and a limiting rib 32. The limiting rib 32 is fixed on the support seat 31. The limiting rib 32 is an elastic member with a certain elastic deformation ability. 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 seat 31, and the lower surface of the comb plate extension section 123 abuts against the limiting rib 32. By setting the elastic deformation parameters of the limiting rib 32 (such as Young's modulus, yield strength, elastic limit, etc.), the limit position of the comb plate 12 moving downward can be predicted, thereby realizing the limit position of the comb plate 12 moving downward, so that the limit position of the wiper plate 13 moving downward can be limited by the comb plate 12.

[0061] In practical applications, the roller brush 11 can rotate counterclockwise ( Figure 3 The wiper 13 can then be used for self-cleaning, fluffing, and other operations. At this point, the comb plate 12 and wiper 13 experience resistance in the opposite direction of the counterclockwise rotation of the roller brush 11, directed generally downward. The elastic deformation of the limiting ribs 32 continuously exerts an upward force on the comb plate 12. These two forces offset each other, maintaining the comb plate 12 and wiper 13 in their original positions as much as possible, ensuring that the wiper 13 maintains good wiping performance.

[0062] Optionally, the contact points between the comb plate body 122 and the support base 31, the contact points between the comb plate extension 123 and the limiting rib 32, and the connection points between the comb end 121 and the comb plate extension 123 are not on a straight line. The above design can form a triangle-like structure, thereby forming a more stable support system. When the roller brush 11 rotates, the comb plate 12 and the wiper plate 13 can be maintained in the set position as much as possible. At the same time, the non-linear arrangement of points can reduce the concentrated transmission of force on a single straight line, which helps to reduce the vibration and noise of the comb plate 12 during operation.

[0063] According to laboratory control studies, when the first angle α1 is in the range of 120 to 170 degrees, the elastic response of the comb plate 12 is more sensitive, and the vibration and noise of the comb plate 12 during operation are relatively mild. Preferably, the first angle α1 is 160 degrees. Similarly, according to laboratory control studies, when the second angle α2 is in the range of 90 to 110 degrees, even if the comb plate 12 is deflected to the maximum angle, the plane M1 on which the end face of the comb end 121 is located (i.e., the extension direction of the comb teeth 1212) can still remain tangent to the first circle ⊙1, thereby maintaining the combing and guiding effect of the comb plate 12 on the hair. Preferably, the second angle α2 is 95 degrees.

[0064] As mentioned above, in actual application, the roller brush 11 rotates clockwise ( Figure 3 Perspective) to clean the floor, the roller brush 11 rotates counterclockwise ( Figure 3 The wiper blade 13 can be configured to perform self-cleaning operations such as fluffing the bristles. To improve the efficiency of the wiper blade 13 in self-cleaning the roller brush 11 while also extending the service life of the roller brush 11, in one feasible embodiment, the wiper end 131 can be configured such that its upper surface is a right angle and its lower surface is rounded. When the roller brush 11 rotates counterclockwise to perform the self-cleaning operation, the bristles on the roller brush 11 will first come into contact with the upper surface of the wiper end 131. Therefore, configuring the upper surface of the wiper end 131 at a right angle can improve the self-cleaning efficiency of the roller brush 11. When the roller brush 11 rotates clockwise to clean the floor, the bristles on the roller brush 11 first come into contact with the lower surface of the wiper end 131. Therefore, the rounded corners on the lower surface of the wiper end 131 can reduce wear on the bristles by the wiper end 131, thereby extending the service life of the roller brush 11. Because the roller brush 11 rotates clockwise for much longer than counterclockwise, the above-mentioned structure of the wiper end 131 can improve the self-cleaning efficiency of the roller brush 11 while also effectively balancing the service life of the roller brush 11.

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

[0066] In one feasible embodiment, the cleaning device further comprises a fluid distributor 2, wherein the fluid distributor 2 is positioned adjacent to the roller brush 11, and the sewage suction port is located adjacent to the fluid distributor 2. Multiple water outlets 21 are evenly distributed along the length of the fluid distributor 2, and the fluid distributor 2 can utilize the water outlets 21 to spray cleaning medium onto the roller brush 11. In this way, when the roller brush 11 cleans the surface to be cleaned, the cleaning medium attached to the bristles of the roller brush 11 can soften dirt, thereby helping the roller brush 11 to more effectively pick up dirt. Furthermore, the fluid distributor 2 and the roller brush 11 are positioned relative to each other in such a manner that the fluid distributor 2 is positioned outside the roller brush 11, the length of the fluid distributor 2 is parallel to the axial direction of the roller brush 11, and the length of the fluid distributor 2 is substantially equal to or greater than the axial length of the roller brush 11. This structure enables the fluid distributor 2 to spray the cleaning medium evenly along the entire length of the roller brush 11, ensuring that the entire surface of the roller brush is covered by the cleaning medium, 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, when the roller brush is worn, the diameter of the roller brush will become smaller), thereby ensuring that the cleaning medium can be evenly sprayed in the entire axial direction of the roller brush.

[0067] The scraper assembly is fixedly mounted on the fluid distributor 2, and the vertical positional relationship between the scraper assembly and the fluid distributor 2 is linked to the rotational direction of the roller brush 11. Specifically, when the roller brush 11 rotates in a first direction, it passes through the scraper assembly before passing through the fluid distributor 2. For example, if the first rotational direction is clockwise, the scraper assembly is located below the fluid distributor 2. Furthermore, the scraper assembly and the fluid distributor 2 are movable relative to the roller brush 11, ensuring that the scraper assembly maintains interference contact with the roller brush 11.

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

[0069] In actual use, the rotating roller brush 11 exerts an upward or downward force on the wiper blade 13 relative to the surface being cleaned. This force pushes the wiper blade 13 up and down, causing the wiper end 131 to lose contact with the bristles or to overextend into the bristles. Loss of contact between the wiper end 131 and the bristles prevents the wiper blade 13 from removing dirty water, while overextending the wiper end 131 into the bristles can cause excessive wear and even affect the normal rotation of the roller brush 11. To address these issues, the vertical movement range of the wiper blade 13 needs to be limited.

[0070] In this embodiment, the wiper end 131 of the wiper blade 13 is located below the water outlet end 21 of the fluid distributor 2 and is as close to the water outlet end 21 as possible without affecting the liquid spraying of the water outlet end 21, so as to make the structure of the cleaning device more compact and utilize the fluid distributor 2 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 extreme position of the wiper blade 13 moving upward or toward the roller brush 11 is limited by the extreme position of the fluid distributor 2 floating upward or moving toward the roller brush 11. The extreme position of the wiper blade 13 moving downward or moving away from the roller brush 11 is also limited by the extreme position of the fluid distributor 2 floating downward or moving away from the roller brush 11. When the fluid distributor 2 is fixed, the fluid distributor 2 cannot move, so the wiper blade 13 is essentially immobile, except for its own elastic deformation. Furthermore, since the suction port is located near the fluid distributor 2, the wiper end 131 is positioned as close to the outlet end 21 as possible. This also facilitates the suction motor to quickly draw the wastewater scraped by the wiper end 131 into the suction port. The scraped dirt can then be immediately moistened with the clean cleaning medium by the roller brush 11, preparing it for the next floor wipe.

[0071] It should be noted that because space is required below the fluid distributor 2 to accommodate the wiper blade 13 and comb plate 12, this space creates unintended floating space beneath the floating fluid distributor 2. This can lead to excessive downward movement of the wiper blade 13 and / or comb plate 12, resulting in the floating fluid distributor 2 being unable to effectively limit the downward movement of the wiper blade 13. To address this issue, the support base 31 and limiting ribs 32 can be used to limit the downward movement of the wiper blade 13. For details on this, please refer to the previous embodiment and will not be elaborated here.

[0072] In order to simplify the assembly process of the comb plate 12 and the wiper 13, in a feasible embodiment, at least one countersunk hole 1221 and at least one alignment hole 1222 are provided on the comb plate body 122, and the wiper body 132 is correspondingly provided with a mounting hole 1321 and a positioning hole 1322, so that when the comb plate body 122 and the wiper body 132 are attached 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 bottom of the fluid distributor 2 is provided with a corresponding number of screw holes (not shown). When the wiper plate 13 and the comb plate 12 need to be installed on the bottom of the fluid distributor 2, the operator can sequentially insert the countersunk bolts through the countersunk holes 1221, the mounting holes 1321, and the screw holes, and then tighten the countersunk bolts to fix the comb plate 12 and the wiper plate 13 to the fluid distributor 2. Furthermore, the bottom of the fluid distributor 2 is also provided with at least one positioning post (not shown). When the wiper plate 13 and the comb plate 12 need to be installed on the bottom of the fluid distributor 2, the operator can first sequentially insert the positioning post into the positioning hole 1322 and the alignment hole 1222 to align the comb plate 12 and the wiper plate 13, thereby facilitating the subsequent insertion of the countersunk bolts through the countersunk holes 1221, the mounting holes 1321, and the screw holes. In addition, since the sewage 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 fitting clearance 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] Regarding the parameters of the comb plate 12, the wiper plate 13, and the comb teeth 1212, please refer to the results in Table 1 and Table 2, where Table 1 and Table 2 are tables generated after Doe (Design of Experiments).

[0076]

[0077]

[0078] Table 2 (Comb parameter analysis table)

[0079]

[0080]

[0081] Laboratory tests have shown that dry hair is more likely to be entangled 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-entanglement effect is better, and no more than 3-5 hairs are entangled; 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-entanglement effect is best, and there is basically no entanglement. The optimal parameter combination of the comb plate 12, the wiper plate 13, and the comb teeth 1212 is: the thickness range of the wiper plate 13 is 0.6mm to 2mm, the thickness range of the comb plate 12 is 0.5mm to 1.5mm, the root width d2 of the comb teeth 1212 is 1mm to 3mm, the top width d3 of the comb teeth 1212 is 0.5mm to 2mm, the length d4 of the comb teeth 1212 is 1.3mm to 3mm, the gap d5 between two adjacent comb teeth 1212 is 1mm to 3mm, and the number of comb teeth 1212 is 42 to 84.

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

[0083] In practice, the length and thickness of the comb teeth 1212 are important factors affecting the combing effect. When the comb teeth 1212 extend tangentially to the roller brush 11, if the comb teeth 1212 are too long, hair will become entangled with the comb teeth 1212, hindering the hair from being sucked out from between the comb teeth 1212. If the comb teeth 1212 are too short, the combing effect will be reduced. If the comb teeth 1212 are too thick, the combing effect will be reduced, while if the comb teeth 1212 are too thin, the comb teeth 1212 will easily break.

[0084] Preferably, the comb plate 12 is made of metal, the thickness of the comb plate 12 (ie, the comb teeth 1212) is 0.6 mm, the root width d2 of the comb teeth 1212 is 2 mm, the top width d3 of the comb teeth 1212 is 1 mm, and the length d4 of the comb teeth 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 3 mm, and when the number of comb teeth 1212 is 84, the gap d5 between two adjacent comb teeth 1212 is 1 mm. This design can avoid wasting space due to excessive tooth gaps, and can also avoid obstructing the passage of entangled hair due to excessive tooth gaps.

[0086] Preferably, the comb teeth 1212 are trapezoidal teeth, that is, the shape of the comb teeth 1212 from the tooth top to the tooth root is trapezoidal, the length d4 of the comb teeth 1212 is the extension height from the tooth top 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 of the comb teeth 1212 is the length from the tooth top to the comb plate extension section 123.

[0087] The slot 1211 includes a gap between two comb teeth and an 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 plate extension section 123) toward the comb plate extension section 123. The depth d6 of the slot 1211 extending into the comb plate extension section 123 is 1 mm.

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

[0089] The body system consists of a handle 3, a body 4 and a floor brush 5, wherein the body 4 is usually designed to be upright, and the handle 3 is set on the body 4 so that the operator can maintain a comfortable grip when cleaning. The handle 3 usually contains some control buttons or switches, which are used to start the machine, adjust the cleaning power or control other functions of the floor scrubber. The floor brush 5 is the part that directly contacts the floor or tile to be cleaned, and the floor brush 5 is rotatably connected to the body 4. Under the operation of the operator, the floor brush 5 can move freely on the surface to be cleaned. At the same time, the operator can also control the movement direction and working state of the floor brush 5 by holding the handle 3, and control the floor scrubber to switch between an upright state and an inclined state to adapt to different cleaning needs.

[0090] The cleaning system includes a cleaning component and a drive motor. The cleaning component is usually set in the floor brush 5, which includes one or more rotating roller brushes 11. The roller brush 11 rotates under the drive of the drive motor to pick up dirt on the surface to be cleaned. The bristles of the roller brush 11 are usually made of flannel, nylon, polypropylene or metal wire, etc. The operator can choose different types of roller brushes according to different cleaning needs. For example, a flannel roller brush is suitable for cleaning smooth floors, while a nylon roller brush is suitable for cleaning rough floors or floors with stubborn stains. When the operator needs to clean a tile floor, he can choose a flannel roller brush, and when the operator needs to clean a cement floor, he can choose 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 detergent added, providing the necessary liquid for the cleaning process. The water pump draws cleaning medium from the clean water tank and delivers it to the fluid distributor 2 via a pipe. The fluid distributor 2 evenly sprays the cleaning medium onto the roller brush 11 or the surface to be cleaned, softening the dirt and helping the roller brush 11 to pick up the dirt more effectively.

[0092] The dirt recovery system consists of a sewage 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 in dirt picked up by the roller brush 11. The suction motor generates strong suction to lift dirt from the floor and transfer it to the sewage tank through the recovery channel. The recovery channel connects the suction port and the sewage tank, transferring dirt from the floor to the sewage tank. The sewage tank stores dirty water and dirt collected during the cleaning process.

[0093] The energy system usually includes a rechargeable battery, such as a lithium-ion battery or a nickel-cadmium battery, which can provide the necessary power for the water pump, suction motor and drive motor, so that the floor scrubber can be freed from the constraints of wires and ensure that the floor scrubber can efficiently complete the cleaning task in an environment away from the socket.

[0094] When the floor scrubber is working, the operator can control the body 4 and floor brush 5 of the floor scrubber through the handle 3, so that it can contact the surface to be cleaned in an upright or tilted state. A rechargeable battery is installed inside the body 4 to provide power for the entire machine, while the roller brush 11 in the floor brush 5 is in direct contact with the ground, and the roller brush 11 picks up dirt by rotating. The cleaning medium in the clean water tank is transported to the fluid distributor 2 through the water pump, and then evenly sprayed onto the roller brush 11 or the surface to be cleaned. At the same time, the dirt recovery system starts working, the suction motor generates suction, sucks in the dirt picked up by the roller brush 11 through the suction port, and transports it to the sewage tank through the recovery channel.

[0095] The following describes the working principles of the comb plate and scraper in detail, taking a floor scrubber as an example, in combination with specific application scenarios.

[0096] Application Scenario 1

[0097] Ms. C has a pet cat at home and frequently finds cat hair on the floor. Her own long hair also frequently falls onto the floor, making it difficult to clean manually. To address this, Ms. C purchased a floor scrubber. However, after using it for a while, she discovered that the long hair easily gets tangled in the scrubber's roller brush. This tangled hair not only obstructs contact with the floor, reducing its cleaning effectiveness, but also tangles with the bristles, making it difficult to remove.

[0098] To solve the problem of hair entanglement in the roller brush, Ms. C purchased a new floor scrubber with a hair-cutting function. This floor scrubber has an additional comb plate below the wiper blade. The comb plate fits tightly with the wiper blade, and the comb end of the comb plate has multiple serrated teeth that are in interference contact with the bristles on the roller brush. When the roller brush rotates, the serrated teeth can cut the long hair entangled in the bristles into short hairs and comb the cut short hairs off the bristles. At the same time, the regular arrangement of the comb teeth can also organize and orient the short hairs and bristles. Then, under the suction of the suction motor, the organized short hairs will be quickly sucked into the sewage suction port through the gaps between the comb teeth.

[0099] Because this new scrubber still features a wiper blade, and both the wiper and comb plates have been thinned, the structure remains largely unchanged. The wiper and comb plates remain in the same locations as the old scrubber. Compared to the old scrubber, the new scrubber's wiping function remains intact. Utilizing the wiper's wiping function, the new scrubber leaves minimal residual water stains after cleaning. While retaining the functionality and performance of the old scrubber, this new scrubber also features a brush entanglement prevention feature, effectively eliminating the need to clean brush hair after use.

[0100] As can be seen, the technical solution provided by this application comprises a cleaning device equipped with a fluid distributor, a roller brush, a comb plate, and a wiper. The fluid distributor is located outside the roller brush and can spray a cleaning medium onto the roller brush to enhance its cleaning effectiveness. The wiper is fixed below the fluid distributor, while the comb plate is fixed below the wiper. The fluid distributor stabilizes the wiper, while the comb plate uses the wiper as a support structure, providing a stable mounting platform for the comb plate. This structure fully utilizes the space below the fluid distributor to accommodate the wiper and comb plate, eliminating the need for additional space for the comb plate and the need to modify the original cleaning device structure, ensuring compatibility and operational consistency with existing products. Both the wiper and comb plate are in interference contact with the bristles of the roller brush. As the roller brush rotates, the comb plate first uses its teeth to cut and separate the long hairs entangled in the roller brush. Then, the wiper presses the bristles to remove impurities, sewage, and other contaminants. At the same time, the comb teeth can also comb the bristles to make them regular, which is beneficial for the subsequent wiping operation of the wiper. The present application can reduce the entanglement of long hair on the roller brush through the coordinated work of the comb plate and the wiper, and can further improve the cleaning efficiency of the roller brush.

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