[0005] In view of the above technical problems, the present application provides a cleaning device which can clean the residual water stains on the surface to be cleaned and improve the cleaning effect.

[0006] The present application provides a cleaning device, which comprises a device main body, a rolling brush assembly and a scraping assembly; the device main body has a rolling brush cavity which is open towards the lower side of the device main body, and the rolling brush assembly is rotationally arranged in the rolling brush cavity; the device main body has a first suction port and a second suction port; along the cleaning direction of the cleaning device, the first suction port is located at the front side of the rolling brush cavity and faces the lower side of the device main body, and the second suction port is located at the rear side of the rolling brush cavity and communicates with the rolling brush cavity.

[0007] The scraping assembly comprises a first scraping member which is located at the front side of the first suction port along the cleaning direction of the cleaning device; the first scraping member is movably arranged on the device main body, and the first scraping member is configured to be separated from the surface to be cleaned when the cleaning device moves forward and to be in contact with the surface to be cleaned when the cleaning device is pulled backward.

[0008] When the cleaning device works along the cleaning direction, the first scraping member is lifted away from the surface to be cleaned, the first suction port first sucks the dust, hair, debris and water stains on the surface to be cleaned, then the rolling brush assembly scrubs the surface to be cleaned to remove stubborn stains and rolls up the sundries and cleaning sewage, which is sucked into and collected by the second suction port, and finally the water stains on the surface to be cleaned are scraped clean by the corresponding scraping member; when the cleaning device is pulled backward along the cleaning direction, the first scraping member is lowered to be in contact with the surface to be cleaned, and the first suction port may have residual sewage dropping back to the surface to be cleaned, at which time the first scraping member can scrape off the residual sewage dropped to ensure the cleaning effect.

[0009] As an optional implementation, the ventilation cross-sectional size of the first suction port is larger than that of the second suction port.

[0010] In this way, when the cleaning device moves forward, the first suction port can absorb large-particle impurities and hair, preventing the hair from winding around the roller brush, and the second suction port can absorb small-particle impurities and dirty water, so that the cleaning efficiency is improved.

[0011] As an optional implementation, the first scraping member is arranged to rotate relative to the device body, and when the cleaning device moves forward, the first scraping member is deflected toward the side of the first suction port, so that the first scraping member is separated from the surface to be cleaned.

[0018] As an optional implementation, the rotation axis of the first scraping member is perpendicular to the cleaning direction of the cleaning device; and the axial length of the first scraping member matches the width dimension of the device body.

[0019] In this way, the cleaning range of the first scraping member can cover the width region of the device body, so that the cleaning efficiency is improved.

[0020] As an optional implementation, the device body is provided with a limiting portion outside the front side of the first suction port, and when the first scraping member is separated from the surface to be cleaned, the first scraping member moves to abut against the limiting portion.

[0021] In this way, the lifting distance of the first scraping member is limited, and the first scraping member can return to the working state in time when needed.

[0022] As an optional implementation, the cleaning device comprises a second scraping member and a third scraping member, the second scraping member is arranged at the front side edge of the opening of the roller brush cavity, and the third scraping member is arranged at the rear side edge of the opening of the roller brush cavity; the second scraping member and the third scraping member are configured to abut against the surface to be cleaned during cleaning.

[0023] In this way, whether the cleaning device moves forward or backward, the stains can be scraped off, and the cleaning effect is improved.

[0025] When the roller brush assembly rotates, the flexible part interferes with the second scraping member and the third scraping member.

[0026] In this way, when the cleaning device moves forward or backward, the dirt adhered to the flexible part can be scraped off by the second scraping member or the third scraping member, and the cleaning efficiency is improved.

[0027] As an optional implementation, the device body has an air suction channel, and the air suction channel is in communication with the first suction port and the second suction port respectively.

[0048] Floor scrubbers, vacuum cleaners, and robotic vacuum cleaners are common household cleaning equipment. They wet and scrub floors, collecting dust, hair, debris, and water stains to achieve floor cleaning. Currently, cleaning equipment generally uses a roller brush to scrub the surface to remove stubborn stains, and then sucks in dust, hair, debris, and water stains from the surface through an air intake.

[0049] However, when the suction port sucks the water stains on the surface to be cleaned, part of the water stains will often drip back to the surface to be cleaned. When the cleaning device moves forward in the cleaning direction, the residual water stains that drip will often be cleaned by the subsequent scraping member. When the cleaning device is pulled backward, the residual water stains that drip will affect the cleaning effect.

[0050] To solve the above technical problems, the present application provides a cleaning device which can clean residual water stains and improve the cleaning effect.

[0051] First, the application scenario of the cleaning device provided by the embodiments of the present application will be illustrated.

[0052] The cleaning device provided by the embodiments of the present application is a commonly used cleaning device in families. Specifically, the product type of the cleaning device in the embodiments of the present application can include but is not limited to a floor cleaning machine, a dust collector, a sweeping robot, etc., which is not limited in the embodiments of the present application.

[0053] Figure 1 The structural schematic diagram of the cleaning device provided by the embodiments of the present application when moving forward in the cleaning direction is shown in the figure. Figure 2 The structural schematic diagram of the cleaning device provided by the embodiments of the present application when pulled backward in the cleaning direction is shown in the figure. Figure 3 The structural schematic diagram of the first scraping member provided by the embodiments of the present application when moving forward in the cleaning direction is shown in the figure. Figure 4 The structural schematic diagram of the first scraping member provided by the embodiments of the present application when pulled backward in the cleaning direction is shown in the figure. Figure 5 The second suction port structure provided by the embodiments of the present application is shown in the figure.

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

[0055] As Figure 1 , Figure 2 , the present application provides a cleaning device 10, which comprises a device main body 100, a rolling brush assembly 110 and a scraping assembly 120. The device main body 100 has a rolling brush cavity 101 which is open towards the lower side of the device main body 100, and the rolling brush assembly 110 is rotationally arranged in the rolling brush cavity 101. The device main body 100 has a first suction port 102 and a second suction port 103. In the cleaning direction of the cleaning device 10, the first suction port 102 is located on the front side of the rolling brush cavity 101 and faces the lower side of the device main body 100, and the second suction port 103 is located on the rear side of the rolling brush cavity 101 and communicates with the rolling brush cavity 101.

[0056] The scraping assembly 120 comprises a first scraping member 121 located at the front side of the first suction port 102 along the cleaning direction of the cleaning device 10; the first scraping member 121 is movably arranged on the device body 100, and is configured to be separated from the surface to be cleaned when the cleaning device 10 moves forward, and to be in contact with the surface to be cleaned when the cleaning device 10 moves backward.

[0057] It can be understood that the device body 100 serves as a support structure of the cleaning device 10 for carrying other components; the roller brush assembly 110 is rotatably arranged in the roller brush cavity 101, and can use a roller brush without a roller cloth for scrubbing the surface to be cleaned; the first suction port 102 and the second suction port 103 are arranged on both sides of the roller brush assembly 110 respectively for sucking in large and small particles, hair and cleaning sewage; the scraping assembly 120 can cooperate with the roller brush assembly 110 and the two suction ports to scrape the surface to be cleaned that has been scrubbed, remove residual water stains, and ensure that the surface to be cleaned is quickly dried.

[0058] The first scraping member 121 is movably arranged on the front side of the first suction port 102. Figure 3 , Figure 4 When the cleaning device 10 moves backward, the first scraping member 121 descends and comes into contact with the surface to be cleaned, scraping off the residual water stains dropped from the first suction port 102 and the water stains left after the roller brush assembly 110 is scrubbed; when the cleaning device 10 moves forward, the first scraping member 121 is lifted and moves away from the surface to be cleaned, so that the large particles can pass through the gap between the first scraping member 121 and the surface to be cleaned to be sucked into the first suction port 102; the movable design of the first scraping member 121 enables it to automatically adjust the contact state with the surface to be cleaned according to the moving direction of the cleaning device 10, thereby avoiding unnecessary friction and wear.

[0059] As an optional embodiment, the ventilation cross-sectional size of the first suction port 102 is larger than that of the second suction port 103.

[0060] It can be understood that the cleaning device 10 performs the main cleaning work when moving forward along the cleaning direction; when the cleaning device 10 moves forward along the cleaning direction, the first suction port 102 with a larger ventilation cross-sectional size first sucks in large particles and hair to prevent the hair from winding around the roller brush assembly 110, then the roller brush assembly 110 scrubs the surface to be cleaned to remove stubborn stains and roll up small particles, and finally the second suction port 103 with a smaller ventilation cross-sectional size sucks in small particles and cleaning sewage to complete the cleaning.

[0061] As shown in Figure 3 , Figure 4As an optional embodiment, the first scraping member 121 is arranged to rotate relative to the device body 100; when the cleaning device 10 moves forward, the first scraping member 121 deflects to the side of the first suction port 102, so that the first scraping member 121 is separated from the surface to be cleaned.

[0062] It can be understood that when the cleaning device 10 moves forward, the first scraping member 121 is separated from the surface to be cleaned and is lifted, so that the particulate impurities and hair can pass through the gap between the first scraping member 121 and the surface to be cleaned; when the first scraping member 121 is lifted, it deflects to the side of the first suction port 102, which can prevent water stains from being thrown out to the surrounding environment when the first scraping member 121 is lifted.

[0063] The power for the movement of the first scraping member 121 can be mechanical drive, electric drive or hydraulic drive, etc.

[0064] As an optional embodiment, the cleaning device 10 comprises a roller 107, the roller 107 is rotatably connected to the device body 100, and the device body 100 is configured to move on the surface to be cleaned by the roller 107; the first scraping member 121 is connected to the roller 107, and the rotation axis of the first scraping member 121 is coaxially arranged with the rotation axis of the roller 107.

[0065] It can be understood that the roller 107 is rotatably connected to the device body 100 and can freely rotate under stress; the driving force for the rotation of the roller 107 can be the friction between the roller 107 and the surface to be cleaned, or can be electric power; since the first scraping member 121 is connected to the roller 107 and the rotation axis of the first scraping member 121 is coaxially arranged with the rotation axis of the roller 107, when the roller 107 rotates, the first scraping member 121 can rotate synchronously with the roller 107, and according to the direction of the rotation of the roller 107, the first scraping member 121 is lifted or lowered relative to the surface to be cleaned.

[0066] As an optional embodiment, the cleaning device 10 comprises a roller 107, the roller 107 is rotatably connected to the device body 100, and the device body 100 is configured to move on the surface to be cleaned by the roller 107; the scraping assembly 120 further comprises at least two transmission wheels, one of the at least two transmission wheels is coaxially connected to the roller 107, and the other of the at least two transmission wheels is connected to the first scraping member 121.

[0067] The at least two transmission wheels are gears and are meshed with each other; or the scraping assembly 120 further comprises a flexible transmission member, and the flexible transmission member is arranged around the at least two transmission wheels.

[0068] It can be understood that when the cleaning device 10 moves, the roller 107 rotates to drive the transmission wheels to rotate, and the plurality of transmission wheels are driven by the gears or the flexible transmission member to transmit power to the scraping assembly 120, so that the scraping assembly 120 is lifted or lowered relative to the surface to be cleaned.

[0069] The transmission wheels can be two or more, and the specific number is adjusted according to the actual transmission distance. The transmission wheels can be driven by gears or flexible transmission members. The flexible transmission members are belt-shaped transmission members and can be made of polyurethane, nylon or other materials with good wear resistance.

[0070] For example, the transmission between the roller 107 and the transmission wheel can be driven by friction. The roller 107 is provided with a rotating shaft, and the transmission wheel is provided with a rotating shaft hole. The rotating shaft and the rotating shaft hole are connected in interference. When the cleaning device 10 moves, the roller 107 drives the transmission wheel to rotate because the torque of the roller 107 is greater than the torque of the rotating shaft. The scraping assembly 120 and the transmission wheel can be driven by gears or coaxially connected and driven by friction. When the transmission between the transmission wheels is driven by the flexible transmission member, the flexible transmission member is arranged around two adjacent transmission wheels and is driven by friction.

[0071] As an optional implementation, the rotating axis of the first scraping member 121 is perpendicular to the cleaning direction of the cleaning device 10. The axial length of the first scraping member 121 matches the width dimension of the device body 100.

[0072] It can be understood that the rotating axis of the first scraping member 121 is perpendicular to the cleaning direction of the cleaning device 10. When the first scraping member 121 rotates, the distance between the first scraping member 121 and the surface to be cleaned can be changed. The axial length of the first scraping member 121 matches the width dimension of the device body 100, which can ensure that the scraping member can cover the entire width of the device travel path and ensure that there is no missed area during cleaning.

[0073] As an optional implementation, the device body 100 is provided with a limiting portion 105 at the front side outer edge of the first suction port 102. When the first scraping member 121 is separated from the surface to be cleaned, the first scraping member 121 moves to abut against the limiting portion 105.

[0074] It can be understood that when the cleaning device 10 moves in a single direction for a long distance, the rotating distance of the first scraping member 121 is relatively long. When the cleaning device 10 moves forward, the limiting portion 105 arranged in the lifting direction thereof can limit the lifting height of the first scraping member 121. When the cleaning device 10 is pulled backward, the first scraping member 121 contacts the surface to be cleaned after rotating a certain distance and stops rotating. In this way, the movement distance of the first scraping member 121 is limited within a certain range, so that when the cleaning device 10 changes the moving direction, the first scraping member 121 can reach the working position in time, thereby ensuring the cleaning efficiency. When the first scraping member 121 moves to abut against the limiting portion 105 or abut against the surface to be cleaned, the rotating shaft of the roller 107 and the rotating shaft hole of the transmission wheel slide and rub, and / or the flexible transmission member and the transmission wheel slide and rub, to stop the transmission system from transmitting.

[0075] As an optional implementation, the cleaning device 10 includes a second scraper 122 and a third scraper 123. The second scraper 122 is disposed at the front edge of the opening of the roller brush cavity 101, and the third scraper 123 is disposed at the rear edge of the opening of the roller brush cavity 101. The second scraper 122 and the third scraper 123 are configured to abut against the surface to be cleaned during the cleaning process.

[0076] It is understandable that water stains will remain after the roller brush assembly 110 wipes the surface to be cleaned. By setting a scraper on each of the front and rear edges of the roller brush cavity 101, the water stains on the surface to be cleaned can be effectively scraped off. When the cleaning device 10 moves forward, the third scraper 123 can scrape off the residual water stains. When the cleaning device 10 is pulled back, the second scraper 122 can scrape off the residual water stains.

[0077] As an optional implementation, the roller brush assembly 110 includes a roller brush shaft 111 and a roller brush body 112. The roller brush body 112 is coaxially wrapped around the outside of the roller brush shaft 111, and the roller brush shaft 111 is rotatably connected to the device body 100. The outer wall of the roller brush body 112 has a flexible part 113 integrally formed with the roller brush body 112.

[0078] When the roller brush assembly 110 rotates, there is interference between the flexible part 113 and the second scraper 122 and the third scraper 123.

[0079] Understandably, when the cleaning device 10 is working, the roller brush shaft 111 drives the roller brush body 112 to rotate, and the roller brush body 112 drives the flexible part 113 to rotate to scrub the surface to be cleaned, remove stubborn stains from the surface to be cleaned, and roll up debris. Wet or sticky debris may stick to the flexible part 113 and be difficult to be sucked in by the second suction port 103. Since there is interference between the flexible part 113 and the second scraper 122 and the third scraper 123, when the cleaning device 10 moves forward or backward, the debris stuck to the flexible part 113 can be scraped off by the second scraper 122 or the third scraper 123, so that the relevant debris can be sucked in by the second suction port 103.

[0080] As an optional implementation, the main body of the device 100 has a suction channel 104, which is connected to the first suction port 102 and the second suction port 103 respectively.

[0081] like Figure 1 , Figure 2 The main body 100 of the device has a cavity shell 106, which surrounds and forms a roller brush cavity 101. The side wall of the cavity shell 106 away from the roller brush cavity 101 forms part of the inner wall of the suction channel 104, so that the suction channel 104 extends to the front side of the roller brush cavity 101 and communicates with the first suction port 102.

[0082] It can be understood that the relevant suction element can provide suction force for the first suction port 102 and the second suction port 103 through the suction passage 104, and the dust, debris and water stains sucked by the first suction port 102 and the second suction port 103 can be concentrated and transported to the subsequent processing part of the device through the suction passage 104. Among them, the cavity shell part 106 is arranged to form the rolling brush cavity 101, and simultaneously serves as part of the inner wall of the suction passage 104, and cooperates with other parts of the inner wall to form an extension part of the suction passage 104, so that the suction passage 104 is in communication with the first suction port 102.

[0083] As Figure 5 , as an optional embodiment, the second suction port 103 is arranged along the width direction of the device main body 100, and the suction passage 104 is in communication with the middle position of the length direction of the second suction port 103; the second suction port 103 is arranged to be inclined downward to the device main body 100 from both ends to the middle.

[0084] It can be understood that the second suction port 103 is arranged along the width direction of the device main body 100, and the cleaning range covers the width area of the device main body 100, the suction passage 104 is in communication with the middle position of the length direction of the second suction port 103, the communication port can be circular, square or other shapes convenient for air flow circulation, the suction passage 104 provides negative pressure suction force for the second suction port 103 through the communication port, and the second suction port 103 is arranged in a "v" shape inclined downward to the device main body 100 from both ends to the middle, so that the debris and sewage brought to the second suction port 103 by the flexible part 113 can be collected to the middle position by gravity, enter the suction passage 104 through the communication port, reduce the dependence on suction, and improve the suction effect.

[0085] The present application provides a cleaning device 10, which comprises a device main body 100, a rolling brush assembly 110 and a scraping assembly 120; the device main body 100 has a rolling brush cavity 101, which is arranged to be open downward to the device main body 100, and the rolling brush assembly 110 is arranged to rotate in the rolling brush cavity 101; the device main body 100 has a first suction port 102 and a second suction port 103; along the cleaning direction of the cleaning device 10, the first suction port 102 is located at the front side of the rolling brush cavity 101 and faces downward to the device main body 100, and the second suction port 103 is located at the rear side of the rolling brush cavity 101 and is in communication with the rolling brush cavity 101; the scraping assembly 120 comprises a first scraping part 121, which is located at the front side of the first suction port 102 along the cleaning direction of the cleaning device 10; the first scraping part 121 is movably arranged on the device main body 100, and the first scraping part 121 is configured to separate from the surface to be cleaned when the cleaning device 10 advances, and contact the surface to be cleaned when the cleaning device 10 is pulled backward.
