Description

Technical Field

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

[0002] Floor scrubbers, vacuum cleaners, and robotic vacuum cleaners are common household cleaning equipment. They can wet and scrub the surface to be cleaned, remove dirt and stains, and collect dust, hair, and debris. The water stains remaining on the surface after cleaning are usually removed by scraping with a squeegee.

[0003] To improve the effect of water stains when the brush is pulled back, common cleaning equipment has a scraper on the front side of the brush in the direction of forward movement, which can scrape away residual water stains when the brush is pulled back.

[0004] However, when there is a lot of water residue on the surface to be cleaned, the upward movement of the squeegee will cause water to splash. Utility Model Content

[0005] To address the aforementioned technical problems, this application provides a cleaning device and equipment to solve the problem of water splashing caused by the scraper blades lifting upwards when the cleaning equipment is pulled back.

[0006] This application provides a cleaning device, including a device body, a roller brush assembly, and a scraping assembly; the roller brush assembly is rotatably disposed on the device body; the device body has a suction channel, the suction channel has a suction port, and the suction port is located on the rear side of the roller brush assembly along the cleaning direction of the cleaning device.

[0007] The scraping assembly includes a first scraper, a bracket, and a drive mechanism; the first scraper is located on the front side of the roller brush assembly along the cleaning direction of the cleaning device; the bracket is rotatably connected to the main body of the device; a first end of the first scraper is connected to the bracket and has a gap between it and the rotation center of the bracket, and a second end of the first scraper faces downward of the main body of the device; the drive mechanism is disposed on the main body of the device and is configured to drive the bracket to rotate so that the second end of the first scraper abuts or separates from the surface to be cleaned.

[0008] This application provides a cleaning device that cleans a surface to be cleaned through the cooperation of a roller brush assembly and a scraping assembly. The roller brush assembly is used to scrub the surface to be cleaned, and the scraping assembly is used to scrape the scrubbed surface to remove water stains. The scraping assembly includes a first scraper, a bracket, and a drive mechanism. One end of the first scraper is connected to the bracket, and the other end is used to clean the ground. The drive mechanism is used to drive the bracket to rotate, thereby moving the first scraper. When the first scraper comes into contact with the surface to be cleaned, it can scrape the surface. When the first scraper moves away from the surface to be cleaned, it can remove large particles of debris. The cleaning device can adjust the contact state between the scraper assembly and the surface to be cleaned as needed to adapt to different cleaning requirements. Since there is a gap between the first scraper and the rotation center of the bracket, the movement speed of the first scraper is relatively slow when the bracket rotates. This setting can prevent the first scraper from lifting too quickly, which would stir up residual water stains on the surface to be cleaned and cause water splashing.

[0009] As an optional implementation, the second end of the first scraper is bent toward the rotation center of the bracket relative to the first end of the first scraper, so that when the bracket rotates, it causes the second end of the first scraper to rise or fall vertically.

[0010] With this configuration, the second end of the first scraper can move in an almost vertical position, which can prevent water stains from being splashed into the surrounding environment when the first scraper rises, thus improving cleaning efficiency.

[0011] As an alternative implementation, the cross-sectional profile of the first scraper is at least partially arc-shaped.

[0012] With this configuration, the first scraper can rotate, ensuring that the second end of the first scraper moves approximately vertically.

[0013] As an optional implementation, the drive mechanism includes a first transmission wheel, a second transmission wheel, a drive member, and a flexible transmission member; both the first and second transmission wheels are rotatably disposed on the main body of the device; the drive member is disposed on the main body of the device and configured to drive the first transmission wheel to rotate; the second transmission wheel is connected to the bracket; the flexible transmission member is wound around the first and second transmission wheels so that the first transmission wheel drives the second transmission wheel to rotate and drives the bracket to rotate.

[0014] With this configuration, the driving force can be provided to drive the bracket to rotate through the first and second transmission wheels, thereby causing the second end of the first scraping component to rise or fall vertically, achieving efficient transmission.

[0015] As an optional implementation, the bracket has an arc-shaped portion, the center of which coincides with the rotation center of the bracket, and the edge of the arc-shaped portion is provided with meshing teeth. The second transmission wheel includes a transmission portion and a gear portion that are coaxially fixedly arranged, a flexible transmission component is wound around the transmission portion, and the gear portion meshes with the meshing teeth.

[0016] With this configuration, the flexible transmission component can transmit the power of the first transmission wheel to the second transmission wheel, which in turn drives the bracket to rotate via gears, achieving efficient transmission.

[0017] As an optional implementation, the driving component is a roller, which is rotatably connected to the main body of the device and is used to move the main body of the device on the surface to be cleaned; the first transmission wheel is coaxially connected to the roller.

[0018] With this configuration, the friction of the surface to be cleaned provides driving force for the rollers when the main body of the device moves. The rotation of the rollers drives the first transmission wheel to rotate, thereby realizing power transmission.

[0019] As an optional implementation, the bracket has a rotational stroke. When the bracket is in the rotational stroke, the first transmission wheel drives the flexible transmission member to rotate around the first transmission wheel and the second transmission wheel. When the bracket is at both ends of the rotational stroke and is stationary relative to the main body of the device, the flexible transmission member slides relative to the first transmission wheel.

[0020] With this configuration, when the cleaning device is moving continuously and the support is at both ends of the rotation stroke, the operation of the transmission system can be stopped by the flexible transmission component sliding relative to the first transmission wheel, reducing unnecessary wear and extending the service life of the first scraping component.

[0021] As an optional implementation, the rotation radius of the outer contour of the bracket is greater than or equal to 1 mm.

[0022] With this setup, due to the larger radius of the bracket, the rotation path of the first scraping component is close to a straight line, preventing water stains from being stirred up due to high-speed rotation, thus improving the water stain removal effect.

[0023] As an optional implementation, when the bracket drives the first scraper to deflect downwards towards the end of its stroke, the angle between the extension line of the second end of the first scraper and the horizontal direction is greater than 0° and less than 180°.

[0024] This setting provides an appropriate scraping angle, improving cleaning efficiency.

[0025] As an optional implementation, the device body has a roller brush cavity, which is open towards the lower part of the device body, and the roller brush assembly is rotatably disposed in the roller brush cavity; the first scraping member is located at the front edge of the roller brush cavity along the cleaning direction of the cleaning device.

[0026] With this configuration, when the cleaning device is pulled back, the first scraper can remove the water stains remaining on the roller brush, improving the water stain removal effect when the device is pulled back.

[0027] As an optional implementation, the roller brush assembly includes a roller brush shaft and a roller brush body. The roller brush body is coaxially wrapped around the outside of the roller brush shaft, and the roller brush shaft is rotatably connected to the main body of the device. The outer wall of the roller brush body has a flexible part integrally formed with the roller brush body.

[0028] A second scraper is provided on the rear edge of the roller brush cavity along the cleaning direction of the cleaning device. When the roller brush assembly rotates, there is interference between the flexible part and the second scraper.

[0029] With this design, the second scraper can remove stains and debris adhering to the flexible part, improving cleaning efficiency.

[0030] This application provides a cleaning device, including a device body and the aforementioned cleaning apparatus, wherein the device body and the cleaning apparatus are movably connected.

[0031] The cleaning equipment provided in this application includes the aforementioned cleaning device. When the cleaning equipment is pulled back, the cleaning device can effectively reduce water stains and will not stir up water stains.

[0032] This application provides a cleaning device and equipment. The cleaning device includes a main body, a roller brush assembly, and a scraping assembly. The roller brush assembly is rotatably mounted on the main body. The main body has a suction channel with a suction port located at the rear of the roller brush assembly along the cleaning direction of the cleaning device. The scraping assembly includes a first scraper, a bracket, and a drive mechanism. The first scraper is located at the front of the roller brush assembly along the cleaning direction of the cleaning device. The bracket is rotatably connected to the main body. A first end of the first scraper is connected to the bracket and has a gap between it and the rotation center of the bracket. A second end of the first scraper faces downwards from the main body. The drive mechanism is mounted on the main body and configured to drive the bracket to rotate, causing the second end of the first scraper to contact or separate from the surface to be cleaned. The cleaning device and equipment provided by this application can effectively improve water stains after application and prevent water splashing. Attached Figure Description

[0042] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions 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.

[0048] Floor scrubbers, vacuum cleaners, and robotic vacuum cleaners are common household cleaning devices. They wet and scrub surfaces to remove dirt and stains, and collect dust, hair, and debris. Water stains on the surface can be scraped away with a squeegee after cleaning. To improve water retention, many cleaning devices have a rotating squeegee on the front side of the roller brush in the direction of travel. When the device moves backward, the squeegee contacts the ground to remove water; when moving forward, the squeegee rises to pass over debris.

[0049] However, when there is a lot of residual water, water will accumulate on the front side of the scraper's movement direction. When the scraper is lifted, the accumulated water will be stirred up, causing water to splash.

[0050] To solve the above-mentioned technical problems, this application provides a cleaning device and cleaning equipment. By improving the scraper structure and transmission mechanism, it can effectively scrape off water stains after pulling, while preventing water stains from splashing.

[0051] The following is an example illustrating the application scenarios of the cleaning equipment provided in the embodiments of this application.

[0052] The cleaning device provided in this application embodiment is a commonly used household cleaning device. Specifically, the product type of the cleaning device in this application embodiment may include, but is not limited to, floor scrubbers, vacuum cleaners, robot vacuum cleaners, etc. This application embodiment does not make specific limitations in this regard.

[0053] Figure 1 A schematic diagram of the structure of the cleaning device provided in this application when it moves along the cleaning direction; Figure 2 This is a schematic diagram of the structure of the cleaning device provided in the embodiment of this application when it is pulled back along the cleaning direction; Figure 3 A schematic diagram of the scraping assembly transmission when the cleaning device provided in this application moves along the cleaning direction; Figure 4 A schematic diagram of the scraping component transmission when the cleaning device provided in this application is pulled backward along the cleaning direction.

[0054] It should be noted that the cleaning direction described in the text is... Figures 1-4 The direction shown.

[0055] like Figure 1 , Figure 2 This application provides a cleaning device, including a device body, a roller brush assembly 100 and a scraping assembly 200; the roller brush assembly 100 is rotatably disposed on the device body; the device body has a suction channel 300, the suction channel 300 has a suction port 310, and the suction port 310 is located on the rear side of the roller brush assembly 100 along the cleaning direction of the cleaning device.

[0056] like Figure 3 , Figure 4 The scraping assembly 200 includes a first scraper 210, a bracket 220, and a drive mechanism 230. The first scraper 210 is located on the front side of the roller brush assembly 100 along the cleaning direction of the cleaning device. The bracket 220 is rotatably connected to the main body of the device. The first end 211 of the first scraper 210 is connected to the bracket 220 and has a gap between it and the rotation center 221 of the bracket 220. The second end 212 of the first scraper 210 faces downward of the main body of the device. The drive mechanism 230 is disposed on the main body of the device and is configured to drive the bracket 220 to rotate so that the second end 212 of the first scraper 210 abuts or separates from the surface to be cleaned.

[0057] Understandably, the main body of the device serves as the foundation of the entire cleaning device, supporting key components such as the roller brush assembly 100 and the scraper assembly 200. The roller brush assembly 100 is rotatably mounted on the main body of the device and is used to scrub the surface to be cleaned and pick up debris. The air intake 310 is located on the rear side of the roller brush assembly 100 along the cleaning direction of the cleaning device and is used to suck up the debris picked up by the roller brush assembly 100 and transport it to the collection device through the air intake channel 300. The scraper assembly 200 is used to scrape off water stains on the ground when the cleaning device is pulled back to ensure that the ground is dry.

[0058] The scraping assembly 200 includes a first scraper 210, a bracket 220, and a drive mechanism 230. The first scraper 210 can be a soft scraper made of soft materials such as PVC, silicone, or rubber. The first scraper 210 is located on the front side of the roller brush assembly 100 along the cleaning direction of the cleaning device. The first end 211 is connected to the bracket 220, and the second end 212 faces downward. When the cleaning device moves, the drive mechanism 230 drives the bracket 220 to rotate, thereby moving the first scraper 210 away from the surface to be cleaned, ensuring that large particles of debris can pass through, or moving the first scraper 210 to contact the surface to be cleaned and scrape off water stains on the ground. Since there is a gap between the first scraper 210 and the rotation center of the bracket 220, the movement speed of the first scraper 210 is relatively slow when the bracket 220 rotates. This setting can prevent the first scraper 210 from lifting too quickly, which would bring up residual water stains on the surface to be cleaned and cause water splashing.

[0059] As an optional implementation, the second end 212 of the first scraper 210 is bent relative to the first end 211 of the first scraper 210 toward the rotation center 221 of the bracket 220, so that when the bracket 220 rotates, it drives the second end 212 of the first scraper 210 to rise or fall vertically.

[0060] Understandably, when the drive mechanism 230 starts and drives the bracket 220 to rotate, the rotation center 221 of the bracket 220 becomes the rotation axis of the entire scraping assembly 200. When the bracket 220 rotates, the second end 212 will move along a curved trajectory. Due to the curved design of the first scraper 210, the movement trajectory of the second end 212 can be vertically raised or lowered. By limiting the degree of curvature of the first scraper 210, the tilt angle of the second end 212 of the first scraper 210 when it contacts the surface to be cleaned can be limited to ensure the scraping effect. At the same time, the lifting angle of the second end 212 can be limited to prevent water stains from being splashed when it is lifted.

[0061] As an alternative implementation, the cross-sectional profile of the first scraper 210 is at least partially arc-shaped.

[0062] It is understandable that, since the first end 211 of the first scraper 210 is fixedly connected to the bracket 220, when the second end 212 bends toward the rotation center 221 of the bracket 220, the cross-sectional profile of the first scraper 210 is at least partially arc-shaped, and the arc-shaped structure can improve the lifting and lowering angles of the second end 212.

[0063] For example, the first scraper 210 is partially bent near the first end 211, and the bending arc can be consistent with the bending arc of the bracket 220. It can remain straight near the second end 212, so that when the bracket 220 rotates, the second end 212 can be raised or lowered vertically.

[0064] As an optional implementation, the drive mechanism 230 includes a first transmission wheel 231, a second transmission wheel 232, a drive member 233, and a flexible transmission member 234; the first transmission wheel 231 and the second transmission wheel 232 are both rotatably disposed on the main body of the device; the drive member 233 is disposed on the main body of the device and configured to drive the first transmission wheel 231 to rotate; the second transmission wheel 232 is connected to the bracket 220; the flexible transmission member 234 is wound around the first transmission wheel 231 and the second transmission wheel 232, so that the first transmission wheel 231 drives the second transmission wheel 232 to rotate, and drives the bracket 220 to rotate.

[0065] Understandably, as the starting point of the transmission system, the first transmission wheel 231 is rotatably mounted on the main body of the device, responsible for receiving the driving force from the driving member 233, and transmitting the driving force to the second transmission wheel 232 through the flexible transmission member 234. The rotation of the second transmission wheel 232 drives the bracket 220 to rotate, thereby driving the first scraping member 210 to rise or fall.

[0066] Among them, the first transmission wheel 231 and the second transmission wheel 232 can be gears, and the flexible transmission component 234 is a belt transmission component, which can be a material with good wear resistance such as polyurethane or nylon.

[0067] As an optional implementation, the bracket 220 has an arc-shaped portion 222, the center of which coincides with the rotation center 221 of the bracket 220. The edge of the arc-shaped portion 222 is provided with meshing teeth 223. The second transmission wheel 232 includes a transmission portion 2321 and a gear portion 2322 that are coaxially fixed. A flexible transmission member 234 is wound around the transmission portion 2321. The gear portion 2322 meshes with the meshing teeth 223.

[0068] It is understandable that, since the center of the arc-shaped portion 222 of the bracket 220 coincides with the rotation center 221 of the bracket 220, when the bracket 220 rotates, the arc-shaped portion 222 will perform circular motion around the rotation center 221. The gear portion 2322 of the second transmission wheel 232 and the meshing teeth 223 of the arc-shaped portion 222 can mesh stably without excessive compression leading to wear or separation. The flexible transmission component 234 is wrapped around the transmission portion 2321 and drives the transmission portion 2321 to rotate through friction, thereby driving the second transmission wheel 232 to rotate.

[0069] As an optional implementation, the driving component 233 is a roller, which is rotatably connected to the main body of the device and is used to move the main body of the device on the surface to be cleaned; the first transmission wheel 231 is coaxially connected to the roller.

[0070] It is understandable that when the main body of the device moves on the surface to be cleaned, the friction between the roller and the ground generates a drive, the rotation of the roller drives the first transmission wheel 231 to rotate, and then transmits the power to the second transmission wheel 232 and the bracket 220, which drives the first scraping component 210 to rotate.

[0071] For example, the roller has a shaft, the first drive wheel 231 has a shaft hole, and the shaft and shaft hole are interference-fitted. Since the torque of the roller is greater than the torque of the shaft, the roller rotates and drives the shaft to rotate. The shaft drives the first drive wheel 231 to rotate through friction.

[0072] Optionally, the drive unit 233 can be driven by an external drive element, such as an electric drive or a hydraulic drive. The drive unit 233 generates rotational power through the external drive element and transmits it to the first transmission wheel 231.

[0073] As an optional implementation, the bracket 220 has a rotational stroke. When the bracket 220 is in the rotational stroke, the first transmission wheel 231 drives the flexible transmission member 234 to rotate around the first transmission wheel 231 and the second transmission wheel 232. When the bracket 220 is at both ends of the rotational stroke and is stationary relative to the main body of the device, the flexible transmission member 234 slides relative to the first transmission wheel 231.

[0074] Understandably, when the bracket 220 is in its rotational stroke, the second end 212 of the first scraper 210 is in its lifting or lowering stroke, and the flexible transmission member 234 transmits power to the first transmission wheel 231 through friction. When the bracket 220 is at either end of its rotational stroke, the second end 212 of the first scraper 210 is in contact with the surface to be cleaned or is in a lifted state, the bracket 220 is stationary relative to the main body of the device, and the flexible transmission member 234 slides relative to the first transmission wheel 231, which can avoid unnecessary wear and realize the non-working state of the transmission system.

[0075] As an optional implementation, the rotation radius of the outer contour of the bracket 220 is greater than or equal to 1 mm.

[0076] It is understandable that a larger rotation radius usually means that the bracket 220 has better stability during rotation. By limiting the rotation radius of the outer contour of the bracket 220 to be greater than or equal to 1mm, the linear speed of the first scraping part 210 can be slower during rotation, so as not to cause water splashing due to high-speed flipping, thus improving the water stain effect.

[0077] Preferably, the rotation radius of the outer contour of the bracket 220 is 30mm to 100mm. At this time, the first scraper 210 will not stir up water during rotation due to its slow linear speed, and the first scraper 210 can return to the working state in time.

[0078] As an optional implementation, when the bracket 220 drives the first scraper 210 to deflect downwards to the end of its stroke, the angle between the extension line of the second end 212 of the first scraper 210 and the horizontal direction is greater than 0° and less than 180°.

[0079] It is understandable that the angle between the extension line of the second end 212 of the first scraper 210 and the horizontal direction determines the effect of scraping water stains to a certain extent. If the angle is greater than 0° and less than 180°, it means that the second end 212 of the first scraper 210 will not be completely parallel to the surface to be cleaned.

[0080] Preferably, the angle between the extension line of the second end 212 of the first scraping member 210 and the horizontal direction is greater than or equal to 45° and less than or equal to 90°, at which point the scraping effect is optimal.

[0081] As an optional implementation, the device body has a roller brush cavity, which is open towards the lower part of the device body, and the roller brush assembly 100 is rotatably disposed in the roller brush cavity; the first scraping member 210 is located at the front edge of the roller brush cavity along the cleaning direction of the cleaning device.

[0082] Understandably, when the main body of the device moves forward in the cleaning direction, the first scraper 210 is raised, and large particles of debris can pass through the gap between the first scraper 210 and the surface to be cleaned and enter the bottom of the roller brush chamber, where they are rolled up by the roller brush assembly 100. When the main body of the device is pulled back in the cleaning direction, the roller brush assembly 100 first scrubs the surface to be cleaned and leaves water stains. The first scraper 210 then descends to contact or press against the surface to be cleaned, removing the water stains.

[0083] As an optional implementation, the roller brush assembly 100 includes a roller brush shaft 110 and a roller brush body 120. The roller brush body 120 is coaxially wrapped around the outside of the roller brush shaft 110, and the roller brush shaft 110 is rotatably connected to the main body of the device. The outer wall of the roller brush body 120 has a flexible part 130 integrally formed with the roller brush body 120.

[0084] A second scraper 240 is provided on the rear edge of the roller brush cavity along the cleaning direction of the cleaning device. When the roller brush assembly 100 rotates, there is interference between the flexible part 130 and the second scraper 240.

[0085] Understandably, during the cleaning process, the roller brush shaft 110 rotates, causing the flexible part 130, which is integrally formed with the roller brush body 120, to rotate. The flexible part 130 makes interference contact with the surface to be cleaned. During the rotation, the flexible part 130 scrubs the surface to be cleaned and rolls up debris. Some sticky or wet debris will stick to the flexible part 130 and be difficult to be sucked in by the air intake 310. By providing a second scraper 240 on the rear edge of the roller brush cavity along the cleaning direction of the cleaning device, and by having an interference amount between the flexible part 130 and the second scraper 240, the stuck debris can be scraped off and enter the air intake channel 300.

[0086] The flexible part 130 can be made of soft materials such as PVC, silicone, or rubber.

[0087] This application provides a cleaning device, including a device body and the aforementioned cleaning apparatus, wherein the device body and the cleaning apparatus are movably connected.

[0088] Understandably, the main body of the equipment is the main structural part of the cleaning equipment, supporting the weight of the entire equipment, providing installation space and interfaces for the cleaning device, which is movably connected to the main body of the equipment and used to clean the surface to be cleaned.

[0089] This application provides a cleaning device and cleaning equipment. The cleaning device includes a main body, a roller brush assembly 100, and a scraping assembly 200. The roller brush assembly 100 is rotatably mounted on the main body. The main body has a suction channel 300 with a suction port 310 located at the rear of the roller brush assembly 100 along the cleaning direction of the cleaning device. The scraping assembly 200 includes a first scraper 210, a bracket 220, and a drive mechanism 230. The first scraper 210 is located at the front of the roller brush assembly 100 along the cleaning direction of the cleaning device. The bracket 220 is rotatably connected to the main body. The first end 211 of the first scraper 210 is connected to the bracket 220 and has a gap between it and the rotation center 221 of the bracket 220. The second end 212 of the first scraper 210 faces downward towards the main body.
