Abstract
Description
Technical Field
[0001] This application relates to the field of cleaning product technology, and more particularly to a cleaning device. Background Technology
[0002] Vacuum cleaners, floor scrubbers, and robotic vacuum cleaners are common household cleaning devices. Many of these devices offer multiple functions, including vacuuming and mopping.
[0003] In related technologies, cleaning equipment with vacuuming and mopping functions typically uses a floor brush to clean the floor. The floor brush is equipped with a roller brush and a water tank. The surface of the roller brush is covered with an absorbent mop cloth, and the water tank supplies cleaning water to wet the mop cloth on the roller brush. The wetted roller brush rolls on the floor to achieve a wet mopping cleaning effect. After cleaning the floor, the mop cloth containing wastewater needs to be removed from the roller brush for washing and drying, or the cleaning equipment needs to be placed on a matching drying station to dry the mop cloth to prevent odors from developing.
[0004] However, currently, after cleaning equipment completes the cleaning process, drying and cleaning the roller brush is time-consuming and labor-intensive, and the accompanying drying equipment occupies extra space and is costly. Utility Model Content
[0005] This application provides a cleaning device to solve the technical problems of current cleaning devices where the roller brush drying and cleaning is time-consuming and labor-intensive, and the accompanying drying equipment occupies additional space and is costly.
[0006] This application provides a cleaning device, which includes a device body, a roller brush, a scraper, a water spraying assembly, and a suction assembly. The device body has a roller brush cavity with an opening facing downwards. The device body is provided with a water collection tank, which at least partially surrounds the roller brush cavity. The roller brush is rotatably disposed in the roller brush cavity, and a portion of the roller brush structure protrudes from the opening to the bottom of the device body. The scraper is disposed at the edge of the opening. The water spraying assembly is configured to spray water onto at least one of the roller brush and the surface to be cleaned below the device body. The suction assembly is disposed on the device body and has a suction port that communicates with the water collection tank.
[0007] The cleaning device provided in this application uses a roller brush to directly contact the surface to be cleaned, without a mop. As the roller brush rotates, it carries wastewater from the floor into its chamber, where it is then ejected and drips into a collection tank. The wastewater in the tank can then be removed by a suction unit. Because the dirt adheres to the surface of the roller brush without penetrating its interior, it can be cleaned simply by rotating and scraping the brush. After cleaning, there is no need to dry the roller brush, saving time and effort. Furthermore, it eliminates the need for a separate drying device, saving space and reducing product costs.
[0008] As an alternative implementation, the roller brush may include a roller body and a roller brush shaft, with the roller body coaxially connected to the roller brush shaft; the roller body is made of a flexible material and is configured to contact the surface to be cleaned.
[0009] With this configuration, the rollers can squeeze and rub the surface to be cleaned, causing the stains to adhere to the roller surface and carrying the wastewater to the collection tank, resulting in a more efficient cleaning effect.
[0010] As an alternative implementation, the water collection trough is positioned below the rotation center of the roller brush in the vertical direction.
[0011] With this design, the wastewater ejected and scraped out by the roller brush is more likely to enter the collection tank under the action of centrifugal force and weight, preventing the wastewater from falling back to the ground.
[0012] As an alternative implementation, the edge of the water collection trough is connected to the cavity wall of the roller brush chamber, and the edge of the vertical projection of the roller brush is at least partially located within the water collection trough.
[0013] With this configuration, the wastewater on the wall of the roller brush chamber can flow down the wall into the collection tank, improving the efficiency of wastewater collection.
[0014] As an alternative implementation, the water collection tank is arranged around the circumferential edge of the opening.
[0015] With this design, wastewater carried up from different locations around the roller brush can be collected in the water collection tank when it is thrown out and dripped under gravity and centrifugal force, ensuring that the area corresponding to the roller brush has a good cleaning effect.
[0016] As an optional implementation, the cleaning device provided in this application may further include a squeegee, which is disposed in the roller brush cavity, extends toward the roller brush and contacts the roller brush; the squeegee is configured to scrape the sewage on the surface of the roller brush into the water collection tank when the roller brush rotates.
[0017] This setup allows for the removal of dirt and water stains from the roller brush surface, which are then collected in the water collection tank, preventing residue and wastewater from remaining on the roller brush.
[0018] As an optional implementation, the wiping component may include a first wiping component and a second wiping component, wherein the first wiping component is located on the front side of the roller brush along the cleaning direction of the cleaning device, and the second wiping component is located on the rear side of the roller brush along the cleaning direction of the cleaning device.
[0019] Wherein, the first wiper component is parallel to the axial direction of the roller brush; and / or, the second wiper component is parallel to the axial direction of the roller brush.
[0020] With this setup, as the cleaning equipment moves forward or backward, the squeegee can promptly scrape away the wastewater carried by the roller brush and collect it in the collection tank, preventing wastewater from flowing back to the ground.
[0021] As an alternative implementation, the first wiper is located at the edge of the water collection trough adjacent to the opening; and / or, the contact position of the second wiper with the roller brush is higher than the water collection trough.
[0022] With this configuration, the wastewater and stains scraped off by the first and second squeegees on the roller brush can quickly enter the water collection tank, preventing stains from adhering to the cavity wall of the roller brush chamber and becoming difficult to clean.
[0023] As an optional implementation, the scraping component may include a first scraping component and a second scraping component, wherein the first scraping component is located on the front side of the opening along the cleaning direction of the cleaning equipment, and the second scraping component is located on the rear side of the opening along the cleaning direction of the cleaning equipment.
[0024] The first scraper is inclined downwards from the horizontal direction relative to the roller brush, and the second scraper is also inclined downwards from the horizontal direction relative to the roller brush.
[0025] With this setup, there are scraping parts at both the front and back of the roller brush to wipe and clean the floor together with the roller brush, and the wastewater is collected in the area between the front and back scraping parts, so that the wastewater generated after wetting the floor can be collected into the water collection tank to avoid water stains.
[0026] As an optional implementation, the surface of the roller brush is provided with a scraping part. When the roller brush rotates, the scraping part can scrape the inner wall of the roller brush cavity or the side of the scraping part facing the inside of the roller brush cavity.
[0027] This design allows for better cleaning of dirt and grime adhering to the brush chamber and scraper components as the brush rotates.
[0028] As an alternative implementation, the water spray assembly may include a nozzle located behind the roller brush chamber along the cleaning direction of the cleaning equipment, and the nozzle is opposite to the roller brush.
[0029] This setup allows for more efficient wetting of the floor as the roller brush moves forward to clean.
[0030] As an optional implementation, the sludge suction assembly may include a sludge tank, an air pump, and a sludge suction pipe. The sludge suction pipe is connected to a water collection tank and forms a sludge suction port. The sludge tank is connected to the sludge suction pipe, and the air pump is connected to the sludge tank. The air pump is configured to draw air from the sludge tank to generate suction at the sludge suction port.
[0031] This setup allows for the rapid pumping of wastewater from the collection tank into the wastewater container, preventing wastewater from overflowing during the cleaning process.
[0032] This application provides a cleaning device comprising a main body, a roller brush, a scraping component, a water spraying assembly, and a suction assembly. The main body has a roller brush cavity with an opening facing downwards. A water collection tank is provided on the main body, at least partially surrounding the roller brush cavity. The roller brush is rotatably disposed within the roller brush cavity, with a portion of its structure protruding from the opening to the bottom of the main body. The scraping component is disposed at the edge of the opening. The water spraying assembly is disposed on the main body and configured to spray water onto at least one of the roller brush and the surface to be cleaned below the main body. The suction assembly is disposed on the main body and has a suction port communicating with the water collection tank. Because the dirt adheres to the surface of the roller brush without penetrating its interior, the roller brush can be cleaned simply by rotating and scraping it. Wastewater and dirt are collected in the water collection tank, eliminating the need for a separate drying device to dry the roller brush, saving time and effort, not occupying extra space, and reducing product costs.

[0051] The terms "first," "second," and "third" (if any) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein.
[0052] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such as a process, method, system, product, or maintenance tool that includes a series of steps or units, not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or maintenance tool.
[0053] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0054] Cleaning equipment with vacuuming and mopping functions typically uses a floor brush to clean floors. The floor brush is equipped with a roller brush and a water tank. The water tank supplies water to wet the roller brush, which then rolls on the floor to achieve a wet mopping effect. The floor brush usually also has a suction port to suck up debris and wastewater scraped off the roller brush.
[0055] However, in current cleaning equipment, the roller brush on the floor brush usually contains absorbent mop cloths and other cleaning components. During cleaning, a scraper is used to squeeze the cleaning components and remove the absorbed wastewater. However, the water cannot be completely removed, leaving water stains on the roller brush after cleaning. If the cleaning components are not removed and dried promptly, the floor brush can easily develop odors or even mold. Therefore, current cleaning equipment requires separate drying at a dedicated drying station after cleaning to prevent the mop from developing odors.
[0056] However, drying the mop on the roller brush separately with a drying device after cleaning is not only a waste of time and electricity, but also takes up extra space and is costly.
[0057] To address the aforementioned technical problems, this application provides a cleaning device. This device, through its design of a wastewater collection structure for cleaning floors with a roller brush, eliminates the need for absorbent mops or other covering components on the roller brush. Instead, the roller brush lifts up dirt and wastewater, collecting it in a water collection trough around the roller brush cavity. Even without a mop, the wastewater will not fall back to the floor, and it will not be sucked into the mop and thus cannot be completely squeezed out. Consequently, there is no need for a separate drying device to dry the roller brush, saving time and effort, conserving household space, and reducing product costs.
[0058] The following is an example illustrating the application scenarios of the cleaning equipment provided in the embodiments of this application.
[0059] The cleaning equipment provided in this application embodiment is a cleaning tool with a roller brush structure. Specifically, the product type of the cleaning equipment in this application embodiment may include, but is not limited to, vacuum cleaners, floor scrubbers, sweeping machines, and robotic vacuum cleaners. Depending on the product type, the cleaning equipment provided in this application embodiment can be used to clean floors, wooden floors, marble floors, glass floors, etc. This application embodiment does not make specific limitations on this. The cleaning object of the cleaning equipment is referred to as the "surface to be cleaned" or "floor".
[0060] Figure 1 A cross-sectional view of the location of the roller brush in the cleaning device provided in an embodiment of this application; Figure 2 A cross-sectional view of the roller brush in the cleaning equipment provided in this application embodiment; Figure 3 This is a schematic diagram of the suction path in the cleaning equipment provided in the embodiments of this application.
[0061] See Figures 1 to 3 As shown, this application provides a cleaning device 10, which includes a device body 200 and a roller brush 100. The device body 200 is the main structure of the cleaning device 10, and the device body 200 can move on the ground when the cleaning device 10 cleans the floor. For example, when the cleaning device 10 is a floor scrubber, the device body 200 can be the floor brush of the floor scrubber.
[0062] The device body 200 includes a roller brush cavity 201 with an opening 202 facing downwards. A roller brush 100 is rotatably disposed within the roller brush cavity 201, and a portion of the roller brush 100 protrudes from the opening 202 to the underside of the device body 200. When the cleaning device 10 cleans the floor, the roller brush 100 contacts the floor, and as the device body 200 moves, the roller brush 100 rolls and rubs the floor to clean dust and stubborn stains.
[0063] In some embodiments, the cleaning device 10 further includes a scraper 300. The scraper 300 is disposed on the device body 200. The scraper 300 is located at the edge of the opening 202, and when the cleaning device 10 cleans the floor, the scraper 300 can scrape the floor to remove stubborn stains. In addition, the scraper 300 can cooperate with the roller brush 100 to scrape and collect water stains and particulate debris on the floor, so that the device body 200 can suck wastewater and particulate debris into the interior of the cleaning device 10.
[0064] The cleaning device 10 provided in this embodiment further includes a water spraying assembly 400 and a suction assembly 500. The water spraying assembly 400 is disposed on the device body 200 and is configured to spray water onto at least one of the roller brush 100 and the surface to be cleaned below the device body 200. The suction assembly 500 is disposed on the device body 200 and is used to suck wastewater and particulate debris generated during cleaning into the interior of the cleaning device 10.
[0065] The main body 200 of the device is equipped with a water collection tank 203, which at least partially surrounds the roller brush cavity 201. The suction assembly 500 has a suction port 501, which is connected to the water collection tank 203. Wastewater scraped up by the rotating roller brush 100 can enter the water collection tank 203, and the suction assembly 500 can remove the wastewater from the water collection tank 203.
[0066] Understandably, the water spray assembly 400 can spray cleaning water onto the surface of the roller brush 100, which then carries the water to the ground to wet it. Alternatively, the water sprayed by the water spray assembly 400 can naturally flow onto the ground. As the roller brush 100 rotates, it contacts and rubs against the wetted ground, removing stubborn stains. Stains generated during cleaning after the ground is wet can adhere to the surface of the roller brush 100. As the roller brush 100 rotates, these stains can be detached from the roller brush 100 under centrifugal force and enter the water collection tank 203, where they are then sucked into the main body 200 by the suction assembly 500 through the suction port 501. In this way, stains generated after the ground is wetted are not sucked into the roller brush 100 and cannot be squeezed out. After cleaning, the roller brush 100 is relatively dry, requiring no separate drying and producing no odor.
[0067] For example, the roller brush 100 may at least have a surface made of soft rubber material. During the cleaning process, the roller brush 100 mainly lifts up stains and particulate matter through friction and adheres the stains to the surface. The stains are not sucked into the deep interior of the roller brush 100 from its surface. Therefore, the stains and particulate matter lifted by the roller brush 100 can be cleaned by centrifugal force and frictional squeezing.
[0068] It should be noted that in the cleaning device 10 provided in this application embodiment, the outer surface of the roller brush 100 can directly contact the ground. The outer side of the roller brush 100 is wrapped with cleaning components made of absorbent materials such as mops. When the roller brush 100 rotates to clean, it can carry the sewage on the ground to the roller brush cavity 201, and the sewage can be thrown out by the roller brush 100 and drip into the water collection tank 203. The sewage in the water collection tank 203 can be sucked away by the sewage suction component 500.
[0069] Since the stains adhere to the surface of the roller brush 100 without penetrating into its interior, the roller brush 100 can be cleaned simply by rotating and scraping it. After cleaning, there is no need to dry the roller brush 100, which saves time and effort. Furthermore, it eliminates the need for separate drying equipment, does not take up extra space, and reduces product costs.
[0070] Please continue to refer to Figures 1 to 3 In some embodiments, the roller brush 100 may include a roller body 110 and a roller brush shaft 120, with the roller body 110 and the roller brush shaft 120 coaxially connected. The roller body 110 is made of a flexible material and is configured to contact the surface to be cleaned. When the roller brush 100 rubs against the ground, the roller body 110 can compress the ground and produce elastic deformation, thereby increasing the friction between the roller brush 100 and the ground to remove stubborn stains and improve the cleaning effect.
[0071] Understandably, the roller brush shaft 120 can rotate with the main body 200 of the equipment. The roller brush 100 has a cylindrical structure, and the axis of rotation of the roller brush 100 relative to the main body 200 of the equipment can be approximated as the axis of the roller brush 100. The roller 110 can squeeze and rub the surface to be cleaned, causing the stains to adhere to the surface of the roller 110, and carrying the wastewater to the collection tank 203, resulting in a more efficient cleaning effect.
[0072] For example, the roller 110 can be made of soft plastic material, including but not limited to PVC (polyvinyl chloride), PE (polyethylene) or other elastic and soft plastic materials. Alternatively, the roller 110 can be made of rubber, silicone or other materials. This application embodiment does not specifically limit this.
[0073] In this embodiment, the water collection trough 203 is positioned below the rotation center of the roller brush 100 in the vertical direction. This makes it easier for the wastewater thrown out and scraped by the roller brush 100 to enter the water collection trough 203 under the action of centrifugal force and weight, thus preventing the wastewater from falling back to the ground.
[0074] Understandably, the water collection trough 203 can be located inside the roller brush chamber 201, with the water collection trough 203 positioned near the bottom of the main body 200. Relative to the center of gravity of the roller brush 100, the water collection trough 203 is positioned lower. During the rotation of the roller brush 100, dirt and particles thrown out by centrifugal force will fall back under gravity. The lower-positioned water collection trough 203 can collect more of the falling dirt and particles.
[0075] For example, the water collection tank 203 can be set close to the opening 202 of the roller brush chamber 201, so as to maximize the collection of sewage and prevent sewage from flowing back to the ground.
[0076] In some embodiments, the edge of the water collection trough 203 is connected to the cavity wall of the roller brush cavity 201, and the edge of the vertical projection of the roller brush 100 is at least partially located within the water collection trough 203, so that the sewage on the cavity wall of the roller brush cavity 201 can flow along the cavity wall into the water collection trough 203, thereby improving the efficiency of sewage collection.
[0077] It is understandable that the shape of the roller brush cavity 201 can match the shape of the outer surface of the roller brush 100, and the edge of the water collection groove 203 can be connected to the lower edge of the cavity wall of the roller brush cavity 201. For example, the groove opening of the water collection groove 203 is located at the position where the lower edge of the cavity wall of the roller brush cavity 201 forms an opening 202, that is, the water collection groove 203 is located inside the edge of the opening 202.
[0078] For example, the water collection tank 203 is arranged around the circumferential edge of the opening 202, so that the sewage carried by the roller brush 100 at different positions around the opening can be collected in the water collection tank 203 when it is thrown out and dripped under gravity and centrifugal force, ensuring that the area corresponding to the roller brush 100 has a good cleaning effect.
[0079] It should be noted that in this embodiment, the roller brush 100 can be arranged along the width direction of the main body 200 of the device. When the cleaning device 10 moves back and forth to clean, the rotation axis of the roller brush 100 is perpendicular to the moving direction of the cleaning device 10. The water collection tank 203 is arranged around the periphery of the opening 202. There are dust collection tanks on the front and rear sides of the roller brush 100 along the cleaning direction to collect water stains. In addition, the two ends of the roller brush 100 along the axial direction can also be connected by the grooves of the water collection tank 203 to form a ring-shaped space for storing sewage. In this way, the sewage carried up by the roller brush 100 can be collected and sucked away through the suction port 501 to avoid the presence of stains in the area cleaned by the roller brush 100.
[0080] Please continue to refer to Figures 1 to 3In one possible implementation, the cleaning device 10 provided in this application embodiment may further include a squeegee 210, which is disposed within the roller brush cavity 201 and extends toward and contacts the roller brush 100. The squeegee 210 is configured to scrape wastewater on the surface of the roller brush 100 into the water collection tank 203 when the roller brush 100 rotates.
[0081] Understandably, dirt and particulate matter adhering to the surface of the roller brush 100 can be scraped off by the squeegee 210 and quickly thrown off by centrifugal force, entering the water collection tank 203, thus preventing dirt and wastewater residue from remaining on the roller brush 100. In this way, the surface of the roller brush 100 can be kept relatively clean and dry after the cleaning operation, without the need for drying equipment.
[0082] In some embodiments, the wiper 210 may include a first wiper 211 and a second wiper 212, wherein the first wiper 211 is located on the front side of the roller brush 100 along the cleaning direction of the cleaning device 10, and the second wiper 212 is located on the rear side of the roller brush 100 along the cleaning direction of the cleaning device 10.
[0083] Understandably, when the cleaning equipment 10 moves forward or backward, the squeegee 210 can promptly scrape away the wastewater carried up by the roller brush 100 and collect it in the water collection tank 203, preventing wastewater from flowing back to the ground. The squeegee 210 and the roller brush 100 can be interference-fitted. The squeegee 210 can be made of elastic materials such as soft rubber or rubber. When the roller brush 100 rolls, the squeegee 210 squeezes the surface of the roller brush 100 and produces elastic deformation, thereby creating a large friction between the squeegee 210 and the roller brush 100 to scrape away stains and attached debris.
[0084] For example, the first wiper element 211 is parallel to the axial direction of the roller brush 100. The length of the first wiper element 211 can be matched with the axial length of the roller brush 100, so that the first wiper element 211 can cover different areas along the length of the roller brush 100, ensuring that water stains at different positions along the length of the roller brush 100 can be wiped away.
[0085] For example, the second wiper 212 is parallel to the axial direction of the roller brush 100. The length of the second wiper 212 can be matched with the axial length of the roller brush 100, so that the second wiper 212 can cover different areas along the length of the roller brush 100, ensuring that water stains at different positions along the length of the roller brush 100 can be wiped away.
[0086] In some embodiments, the first wiper 211 is located at the edge of the water collection trough 203 adjacent to the opening 202. The sewage and stains scraped off the roller brush 100 by the first wiper 211 can quickly enter the water collection trough 203, preventing stains from adhering to the cavity wall of the roller brush cavity 201 and becoming difficult to clean.
[0087] In some embodiments, the contact position between the second squeegee 212 and the roller brush 100 is higher than that of the water collection tank 203. The sewage and stains scraped off by the second squeegee 212 on the roller brush 100 can quickly enter the water collection tank 203, preventing stains from adhering to the cavity wall of the roller brush cavity 201 and becoming difficult to clean.
[0088] It should be noted that when the cleaning device 10 moves forward to clean, the surface of the roller brush 100, after passing the ground, will first pass the second squeegee 212 behind it, and then pass the first squeegee 211 at the front of the roller brush 100. Therefore, the second squeegee 212, which is positioned relatively high, can scrape off the dirt on the surface of the roller brush 100 before it enters the roller brush cavity 201, allowing the dirt to flow into the water collection tank 203. When the surface of the roller brush 100 passes the inner wall of the roller brush cavity 201 and rotates to the front, that is, before contacting the ground, it is scraped by the second squeegee 320 to remove any remaining dirt, ensuring the cleanliness of the roller brush 100 before contacting the ground and achieving a better cleaning effect. When the cleaning device 10 moves backward, the first squeegee 211 and the second squeegee 212 can scrape off the dirt through the reverse process described above, which will not be elaborated here.
[0089] The structure of the scraping component 300 will be described in detail below.
[0090] Please continue to refer to Figures 1 to 3 In one possible implementation, the scraper 300 may include a first scraper 310 and a second scraper 320, with the first scraper 310 located on the front side of the opening 202 along the cleaning direction of the cleaning device 10, and the second scraper 320 located on the rear side of the opening 202 along the cleaning direction of the cleaning device 10.
[0091] The first scraper 310 is inclined downwards from the horizontal direction relative to the roller brush 100, and the second scraper 320 is inclined downwards from the horizontal direction relative to the horizontal direction relative to the roller brush 100.
[0092] Understandably, both the first scraper 310 and the second scraper 320 can come into contact with the ground during the cleaning process, so that the scraper 300 is present in front of and behind the roller brush 100 to wipe and clean the ground together with the roller brush 100, and the wastewater is collected in the area between the front and rear scraper 300, so as to ensure that the wastewater generated after cleaning the wet ground can be collected into the water collection tank 203 and avoid water stains.
[0093] For example, the first scraper 310 can be tilted from the front side to the rear side and downward, and the second scraper 320 can be tilted from the rear side to the front side and downward. The area defined by the two scrapers matches the contour of the lower part of the roller brush 100, so that the roller brush 100 can more easily carry the sewage stains on the ground into the roller brush cavity 201 and collect them into the water collection tank 203.
[0094] For example, both the first scraper 310 and the second scraper 320 can be made of elastic materials such as soft rubber or rubber, and this application embodiment does not specifically limit this.
[0095] In some embodiments, the surface of the roller brush 100 is provided with a scraping portion 130. When the roller brush 100 rotates, the scraping portion 130 can scrape the inner wall of the roller brush cavity 201 or the side of the scraping member 300 facing the inside of the roller brush cavity 201. In this way, the dirt attached to the roller brush cavity 201 and the scraping member 300 can be cleaned when the roller brush 100 rotates, resulting in a better cleaning effect.
[0096] The following examples of different roller brush 100 structures will be used to illustrate in detail the structure and scraping method of the scraping section 130.
[0097] Figure 4 A schematic diagram of the structure of the roller brush in the cleaning equipment provided in this application embodiment. Figure 1 ; Figure 5 for Figure 4 A partial view of position A in the middle.
[0098] Please refer to Figure 4 and Figure 5 and combined Figure 1 In one possible implementation, the roller brush 100 includes a roller body 110 and a rotating shaft, with the roller body 110 coaxially connected to the outside of the rotating shaft. The surface of the roller body 110 is provided with a plurality of scraping portions 130, which are spaced apart along the axial direction of the roller body 110, and ventilation grooves 101 are formed between adjacent scraping portions 130.
[0099] Understandably, when the roller brush 100 contacts and rubs against the ground, the scraping part 130 abuts and rubs against the ground. The scraping part 130 can increase the friction between the roller brush 100 and the ground, resulting in a better stain removal effect. The cleaning device 10 is equipped with a suction component 500, which can create negative pressure to suck stains and particulate debris into the cleaning device 10. When the roller brush 100 rotates to clean, the negative pressure airflow generated by the suction component 500 can flow through the ventilation slot 101. The wastewater and particulate debris carried by the roller brush 100 scraping the ground can flow through the ventilation slot 101 and be sucked into the cleaning device 10 with the airflow.
[0100] In some embodiments, the ventilation groove 101 extends circumferentially along the roller 110. When the roller 110 rotates, the scraping portions 130 on both sides of the ventilation groove 101 can cover the area traversed by the ventilation groove 101, so that the ground area facing the ventilation groove 101 can be scraped by the scraping portions 130 as the roller brush 100 rotates, thereby preventing water stains from remaining.
[0101] It is understood that the ventilation groove 101 is arranged circumferentially around the roller 110 and is in an annular shape. The scraping part 130 is arranged circumferentially around the roller 110 and can be in an annular shape, thereby forming an annular ventilation groove 101 between two adjacent scraping parts 130.
[0102] For example, the roller brush 100 can be arranged along the width direction of the cleaning device 10. When the cleaning device 10 moves back and forth to clean, the rotation axis of the roller brush 100 is perpendicular to the movement direction of the cleaning device 10. The roller brush 100 rotates around its own axis. The edge contour line of the scraping part 130 can be a three-dimensional curve, that is, the edge contour line of the scraping part 130 is not located in a plane perpendicular to the roller brush axis 120. Therefore, when the roller brush 100 rotates, the scraping part 130 can scrape and clean the ground area corresponding to the ventilation groove 101.
[0103] It should be noted that the scraping part 130 can clean the ground by friction, and the ventilation groove 101 between the scraping parts 130 allows airflow, so that sewage and large and small particles of debris can be sucked away through the ventilation groove 101. As the roller brush 100 rotates, the scraping part 130 will scrape the ground area corresponding to the ventilation groove 101, thereby avoiding water stains. In this way, while having a good cleaning effect, the roller brush 100 does not need to be wrapped with a mop on its outer surface. After cleaning, the roller brush 100 is in a relatively dry state, which does not require separate drying and will not produce odor.
[0104] Figure 6 A schematic diagram of the structure of the roller brush in the cleaning equipment provided in this application embodiment. Figure 2 ; Figure 7 for Figure 6 A partial view of position B in the middle.
[0105] Please refer to Figure 6 and Figure 7 and combined Figure 1 In another possible implementation, the roller brush 100 includes a roller 110 and a rotating shaft, with the roller 110 coaxially connected to the outside of the rotating shaft. The surface of the roller 110 is provided with at least one ventilation groove 101, which is arranged circumferentially around the roller 110.
[0106] The scraping part 130 includes a first scraping part 131 and a second scraping part 132. The first scraping part 131 is located outside the ventilation slot 101, and the second scraping part 132 is located inside the ventilation slot 101.
[0107] It is understandable that when the roller brush 100 comes into contact with and rubs against the ground, the first scraping part 131 and the second scraping part 132 can come into contact with and rub against the ground, thereby increasing the friction between the roller brush 100 and the ground and achieving a better stain removal effect.
[0108] In some embodiments, the first end of the second scraping part 132 is connected to one side of the ventilation channel 101 in the width direction, and the second end of the second scraping part 132 is spaced from the other side of the ventilation channel 101 in the width direction. Thus, when particulate matter passes through the ventilation channel 101, the second scraping part 132 can undergo elastic deformation, allowing large particulate matter to pass through. Simultaneously, the second scraping part 132 can prevent water stains from remaining on the ground area corresponding to the ventilation channel 101.
[0109] It should be noted that by providing ventilation grooves 101 on the roller 110, wastewater, stains, and large and small particles can be sucked away through the ventilation grooves 101 when the roller brush 100 cleans the floor. Scraping parts 130 are provided both outside and inside the ventilation grooves 101. During cleaning, the scraping parts 130 can rub and clean the floor. As the roller brush 100 rotates, the scraping parts 130 also scrape the floor area corresponding to the ventilation grooves 101, thus preventing water stains from remaining. While achieving good cleaning results, the roller brush 100 does not require a separate mop cloth to be wrapped around its outer surface. After cleaning, the roller brush 100 is relatively dry, requiring no separate drying and producing no odor.
[0110] In some embodiments, the water spray assembly 400 may include a nozzle located behind the roller brush chamber 201 along the cleaning direction of the cleaning device 10, and opposite the roller brush 100. This allows for more efficient wetting of the floor as the roller brush 100 moves forward to clean.
[0111] Understandably, the nozzle can extend along the axial direction of the roller brush 100, and the length of the nozzle can match the length of the roller brush 100. Multiple water spray holes can be provided on the side of the nozzle facing the roller brush 100, and the multiple water spray holes can be arranged at intervals along the length of the nozzle. In this way, different positions along the length of the roller brush shaft 120 can be wetted, and correspondingly, the area passed by the roller brush 100 can be evenly wetted, achieving a good floor washing effect.
[0112] For example, the main body 200 of the device may be equipped with a clean water tank and a water pump. The inlets of the clean water tank and the water pump are connected, and the outlet of the water pump can be connected to the nozzle. The cleaning tank can supply water to the nozzle through the water pump, so that the cleaning water sprayed from the nozzle has a certain water pressure.
[0113] It should be noted that since the main body of the roller brush 100 can be made of soft rubber, sewage will not be sucked into the deep interior of the roller brush 100, but will only adhere to the surface of the roller brush 100. Therefore, after cleaning, a certain pressure of cleaning water can be sprayed onto the surface of the roller brush 100 through the water spray device, and in conjunction with the rotation of the roller brush 100, the surface of the roller brush 100 can be self-cleaned. After self-cleaning, the surface of the roller brush 100 is relatively dry, and no drying equipment is required, nor will any odor be produced.
[0114] Please continue to refer to Figures 1 to 3 In some embodiments, the suction assembly 500 may include a wastewater tank 510, an air pump 520, and a suction pipe 530. The suction pipe 530 is connected to the water collection tank 203 and forms a suction port 501. The wastewater tank 510 is connected to the suction pipe 530, and the air pump 520 is connected to the wastewater tank 510. The air pump 520 is configured to draw air from the wastewater tank 510 to generate suction at the suction port 501.
[0115] Understandably, both the wastewater tank 510 and the air pump 520 can be installed on the main body 200 of the equipment. The air pump 520 draws from the wastewater tank 510, creating a negative pressure in the wastewater tank 510. This causes the suction pipe 530 to generate an airflow, which flows from the suction port 501 to the wastewater tank 510. Due to the negative pressure, the suction port 501 generates suction, which can quickly draw the wastewater in the collection tank 203 into the wastewater tank 510, preventing the wastewater in the collection tank 203 from overflowing during the cleaning process.
[0116] It should be noted that, in addition to sucking up the sewage in the collection tank 203, the suction port 501 can also directly suck up particulate debris carried up by the roller brush 100 through negative pressure suction. Alternatively, the suction port 501 can suck up the sewage in the collection tank 203 alone, and another suction port can be provided on the rear side of the roller brush chamber 201 along the cleaning direction of the cleaning device 10 to suck up debris, so as to achieve the separation of debris and water stains.
[0117] This application provides a cleaning device comprising a main body, a roller brush, a scraper, a water spray assembly, and a suction assembly. The main body has a roller brush cavity with an opening facing downwards. A water collection tank surrounds the roller brush cavity at least partially. The roller brush is rotatably disposed within the roller brush cavity, with a portion of its structure protruding from the opening to the bottom of the main body. The scraper is disposed at the edge of the opening. The water spray assembly is disposed on the main body and configured to spray water onto at least one of the roller brush and the surface to be cleaned below the main body. The suction assembly is disposed on the main body and has a suction port communicating with the water collection tank. Wastewater and stains are collected in the water collection tank, eliminating the need for a separate drying device to dry the roller brush, saving time and effort, not occupying extra space, and reducing product costs.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
