Description

Technical Field

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

[0002] Floor scrubbers, vacuum cleaners, and robotic vacuum cleaners are common household cleaning equipment. They can wet and scrub the floor, and suck up dust, hair, and debris through the suction port to clean the floor.

[0003] Cleaning equipment typically includes a water tank and a roller brush. The water tank wets the surface to be cleaned through pipes. The roller brush comes in two forms: with a cloth and without a cloth. It is used to scrub the wet floor and pick up debris. The cleaning equipment is also equipped with an air intake to collect water stains and debris from the surface to be cleaned and the roller brush.

[0004] However, the suction power of the air intake of the current cleaning equipment is insufficient, and some water stains will still remain on the surface to be cleaned after cleaning. Utility Model Content

[0005] To address the aforementioned technical problems, this application provides a cleaning device that can improve suction power and effectively improve the cleaning of water stains without increasing noise.

[0006] This application provides a cleaning device, including a device body, a roller brush assembly, a stop member, and a movable member; the roller brush assembly is rotatably disposed on the device body; the device body has a cleaning air duct, and the air inlet end of the cleaning air duct is opposite to the side of the roller brush assembly.

[0007] A stop is provided at the air inlet end. The lower edge of the stop and the bottom of the air inlet end form a first intake port, and the upper edge of the stop and the top of the air inlet end form a second intake port. The height of the first intake port is less than the height of the second intake port. A movable part is movably provided between the stop and the top of the air inlet end to open or block the second intake port.

[0008] The cleaning device provided in this application embodiment uses a stop to separate the air inlet to form a first suction port and a second suction port. The first suction port is located below the second suction port, and the size of the first suction port is smaller than that of the second suction port. This is used to separate large and small particles of debris. During the cleaning process, the roller brush assembly scrapes the surface to be cleaned and picks up particles of debris. The first suction port has strong suction and can absorb small particles of debris and residual water stains. The second suction port can absorb large particles of debris picked up by the roller brush assembly. This cleaning device can effectively reduce water stains on the surface to be cleaned and improve the cleaning effect.

[0009] As an optional implementation, the air inlet is located on the rear side of the roller brush assembly along the cleaning direction of the cleaning equipment, and the first suction port and the second suction port are spaced apart along the circumferential rotation of the roller brush assembly; when the cleaning equipment moves forward, the roller brush assembly rotates and passes through the first suction port first and then the second suction port.

[0010] With this setup, as the cleaning equipment moves forward, the roller brush assembly first scrapes the ground, rolling up particles and leaving water stains on the surface to be cleaned. The roller brush assembly rotates, passing through the first suction port and then the second suction port. The first suction port sucks in small particles of debris, as well as dust and water stains from the surface to be cleaned, while the second suction port sucks in the remaining large particles of debris. The roller brush assembly and the two suction ports work together to improve cleaning efficiency.

[0011] As an alternative implementation, the stop extends along the axial direction of the roller brush assembly; the first suction port and the second suction port are arranged in parallel, and the length of both matches the axial length of the roller brush.

[0012] With this configuration, dirt and particles at different positions along the axis of the roller brush assembly can be effectively guided to the nearest suction port, reducing cleaning dead spots and improving cleaning efficiency.

[0013] As an optional implementation, the cross-sectional width of the stop member on the side near the first intake port is greater than the cross-sectional width of the stop member on the side near the second intake port.

[0014] With this configuration, the stop provides a longer air intake channel for the first intake, which helps stabilize the airflow and more effectively suck up water stains and small particles. Near the second intake, the narrower stop is farther away from the roller brush assembly. Only when the flexible cleaning part pushes large particles can the moving part be pushed away. Opening the second intake can prevent the flexible cleaning part from pushing the moving part away when there are no particles.

[0015] As an optional implementation, the stop member has a guide surface on the side facing the roller brush assembly; the outer surface of the roller brush assembly has a flexible cleaning part, which contacts the guide surface when the roller brush assembly rotates.

[0016] This design, with the flexible cleaning section working in conjunction with the guide surface, helps guide large particles of debris to the second air intake, improving cleaning efficiency.

[0017] As an optional implementation, the end of the movable part near the upper edge of the air inlet is rotatably connected to the main body of the equipment; the end of the movable part near the stop can abut against the side of the stop facing into the clean air duct to close the second suction port, or the end of the movable part near the stop can deflect into the clean air duct to open the second suction port.

[0018] With this configuration, the moving part can open or close the second suction port depending on whether there are large particles of debris. When the second suction port is open, it can suck in large particles of debris. When it is closed, the suction power of the first suction port will increase, thus improving cleaning efficiency.

[0019] As an optional implementation, the movable part is a flexible part, the first end of the flexible part abuts against the upper edge of the air inlet end and is fixed relative to it; the second end of the flexible part can abut against the side of the stop member facing into the cleaning air duct to close the second suction port, or the second end of the flexible part can be deflected relative to the first end of the flexible part in a direction away from the roller brush assembly to open the second suction port.

[0020] With this design, large particles of debris can be pushed by the roller brush assembly to deform the flexible part or move away from the stop, thereby opening the second suction port and improving cleaning efficiency; the flexible part can undergo slight deformation when it comes into contact with the stop, resulting in better sealing; the flexible part has stronger wear resistance, which can ensure the stability and reliability of the moving parts during long-term use.

[0021] As an alternative implementation, the movable component is movably disposed at the air inlet end; the movable component may cover the second suction port, or move relative to the roller brush assembly into the cleaning duct to open the second suction port.

[0022] The cleaning equipment also includes an elastic element that abuts against a movable element and applies a force toward the roller brush assembly to the movable element.

[0023] With this configuration, when there are large particles of debris, the large particles are pushed into the cleaning duct by the roller brush assembly, thereby opening the second suction port. After the large particles of debris are sucked in, the movable part closes the second suction port again under the action of the elastic part, thus improving cleaning efficiency.

[0024] As an alternative implementation, when the movable part blocks the second suction inlet, the lower edge of the movable part is lower than the rotation axis of the roller brush assembly in the height direction of the cleaning device.

[0025] With this configuration, the flexible cleaning unit has sufficient force to act on large particles of debris, pushing the lower edge of the moving part away from the stop, thereby allowing the large particles of debris to be sucked into the second suction port, reducing the accumulation and blockage of dirt near the second suction port, and improving the cleaning quality.

[0026] As an alternative implementation, at least a portion of the lower edge of the first suction inlet extends below the roller brush assembly, and the air intake direction of the first suction inlet is parallel to the horizontal direction, or is inclined downwards relative to the horizontal direction towards the cleaning device.

[0027] This design helps guide airflow from the surface to be cleaned to the first inlet, thereby guiding dust, water stains, and small particles from the surface to be cleaned along the lower edge of the first inlet into the cleaning duct, improving the cleaning effect.

[0028] As an optional implementation, the first suction port extends to the inner side below the roller brush assembly and has a recess, which is disposed adjacent to the lower edge of the stop member.

[0029] With this design, the curved surface of the recess corresponds to the guide surface of the stop, which helps to guide airflow and particulate matter, improving the cleaning effect. Furthermore, during the rotation of the flexible cleaning part, it comes into contact with the lower edge of the first suction inlet and the stop. The transition through the recess can improve the service life of the flexible cleaning part.

[0030] As an optional implementation, the roller brush assembly includes a roller brush shaft and a roller brush body. The roller brush body is coaxially sleeved on the outside of the roller brush shaft. The roller brush shaft is rotatably connected to the main body of the device. The circumferential sidewall of the roller brush body is provided with a flexible cleaning part integrally formed therewith.

[0031] With this configuration, the flexible cleaning section can rotate with the main body of the roller brush to scrub the surface to be cleaned and push particles and debris into the cleaning air duct to ensure the cleaning effect. At the same time, the integrated structure of the main body of the roller brush and the flexible cleaning section can reduce wear and loosening between components and improve the durability and stability of the equipment.

[0032] As an alternative implementation, the device body has a roller brush cover, which is configured to form a roller brush groove that is open towards the bottom of the device body, and the roller brush assembly is rotatably disposed in the roller brush groove; the edge of the roller brush cover is connected to the upper edge of the air inlet.

[0033] This design ensures the stability and cleaning efficiency of the roller brush assembly while also enhancing its aesthetics.

[0034] This application provides a cleaning device, including a device body, a roller brush assembly, a stop member, and a movable member. The roller brush assembly is rotatably mounted on the device body. The device body has a cleaning air duct, with the air inlet end of the cleaning air duct facing the side of the roller brush assembly. The stop member is disposed at the air inlet end, with a first suction port formed between the lower edge of the stop member and the bottom of the air inlet end, and a second suction port formed between the upper edge of the stop member and the top of the air inlet end. The height of the first suction port is less than the height of the second suction port. The movable member is movably disposed between the stop member and the top of the air inlet end to open or block the second suction port. The cleaning device provided by this application can increase the suction power of the first suction port without increasing the device power, effectively reducing water stains and improving the cleaning effect.

[0045] 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, for example, in orders other than those illustrated or described herein.

[0047] 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.

[0048] Floor scrubbers, vacuum cleaners, and robotic vacuum cleaners are common household cleaning devices. They wet and scrub floors, and then suck up dust, hair, and debris through suction ports to clean the floor. Cleaning equipment typically includes a water tank and a roller brush. The water tank wets the surface to be cleaned through pipes. The roller brush, available with or without a cloth, is used to scrub the wet floor and pick up debris. The equipment also has an air intake to collect water and debris from the surface and the roller brush.

[0049] However, the air intake of current cleaning equipment needs to suck in water stains and large particles at the same time. The air intake is set to be large, and in order to reduce noise, the suction power is usually limited, resulting in insufficient suction. After cleaning, there will still be some water stains left on the surface to be cleaned.

[0050] To address the aforementioned technical problems, this application provides a cleaning device that optimizes the structure of the air intake. Two intake ports are arranged on the rear side of the roller brush assembly in the cleaning direction, along the circumferential rotation of the roller brush assembly. The suction power of the other intake port can be increased by closing one of the intake ports, which can effectively improve water stains without increasing the overall cost or noise.

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

[0052] The cleaning equipment provided in this application embodiment is a cleaning equipment with a roller brush structure and a suction structure. The product type of the cleaning equipment in this application embodiment may include, but is not limited to, floor scrubbers, vacuum cleaners, sweeping robots, etc. This application embodiment does not make specific limitations in this regard.

[0053] Figure 1 This is a schematic diagram of the structure of the cleaning device when the second suction port is closed, as provided in the embodiments of this application. Figure 2 This is a schematic diagram of the structure of the cleaning device with the second suction port open, as provided in the embodiments of this application. Figure 3 for Figure 2 A partial view within the context.

[0054] See Figures 1 to 3 This application provides a cleaning device 10, including a device body 100, a roller brush assembly 110, a stop member 101 and a movable member 102; the roller brush assembly 110 is rotatably disposed on the device body 100; the device body 100 has a cleaning air duct 103, and the air inlet end 104 of the cleaning air duct 103 is opposite to the side of the roller brush assembly 110.

[0055] A stop 101 is disposed at the air inlet 104. A first intake port 105 is formed between the lower edge of the stop 101 and the bottom of the air inlet 104, and a second intake port 106 is formed between the upper edge of the stop 101 and the top of the air inlet 104. The height of the first intake port 105 is less than the height of the second intake port 106. A movable member 102 is movably disposed between the stop 101 and the top of the air inlet 104 to open or block the second intake port 106.

[0056] The main body 100 serves as the support for the cleaning equipment 10, providing corresponding structural support. The roller brush assembly 110 is rotatably mounted on the main body 100. Its roller brush can be either a roller brush with a roller cloth or a roller brush without a roller cloth. It can scrape away the stains on the surface to be cleaned and roll up dust, hair, debris and other debris. The cleaning air duct 103 is used to collect and transport the sucked-in dust, hair, debris and water stains.

[0057] It is understandable that by setting a stop 101 at the air inlet 104, the bottom of the stop 101 and the bottom of the air inlet 104 form a first suction port 105, and the top of the stop 101 and the top of the air inlet 104 form a second suction port 106. The distance between the bottom of the stop 101 and the bottom of the air inlet 104 is less than the distance between the top of the stop 101 and the top of the air inlet 104. Therefore, the height of the first suction port 105 is less than the height of the second suction port 106, which can achieve the diversion of particles of different sizes. The first suction port 105 is a flat suction port, which can suck up dirt such as water stains, dust and small particles, while the second suction port 106 can suck up large particles. The second suction port 106 is equipped with a movable part 102. When the movable part 102 opens the second suction port 106, large particles of debris can enter the cleaning air duct 103 through the second suction port 106. When the movable part 102 blocks the second suction port 106, the second suction port 106 is completely closed or leaves a small gap. At this time, the airflow at the air inlet mainly enters from the first suction port 105. The suction of the first suction port 105 is enhanced, which can effectively suck up water stains on the surface to be cleaned.

[0058] As an optional implementation, the air inlet 104 is located on the rear side of the roller brush assembly 110 along the cleaning direction of the cleaning device 10, and the first suction port 105 and the second suction port 106 are arranged at intervals along the circumferential rotation of the roller brush assembly 110; when the cleaning device 10 moves forward, the roller brush assembly 110 rotates and passes through the first suction port 105 first and then the second suction port 106.

[0059] Understandably, when the cleaning device 10 moves along the cleaning direction, the roller brush assembly 110 first scrapes the ground, rolling up particulate debris. The rolled-up particulate debris is sucked in by two suction ports located at the rear of the roller brush assembly 110. The roller brush assembly 110 carries the particulate debris through the first suction port 105 and then through the second suction port 106. The first suction port 105 sucks in small particulate debris and residual water stains on the surface to be cleaned, and the second suction port 106 sucks in the remaining large particulate debris. The roller brush assembly 110 and the two suction ports work together to complete the cleaning of the surface to be cleaned.

[0060] As an optional implementation, the stop 101 extends along the axial direction of the roller brush assembly 110; the first suction port 105 and the second suction port 106 are arranged in parallel, and the length of both matches the axial length of the roller brush.

[0061] It is understood that the stop 101 extends along the axial direction of the roller brush assembly 110, and both ends of the stop 101 can be connected to the main body 100 of the equipment. The first suction port 105 and the second suction port 106 are formed by the stop 101 separating the air inlet end 104 and are parallel to each other. The lengths of the first suction port 105 and the second suction port 106 are consistent with the lengths of the stop 101 and the roller brush, which can reduce cleaning dead angles and improve cleaning efficiency.

[0062] As an optional implementation, the cross-sectional width of the stop member 101 on the side near the first intake port 105 is greater than the cross-sectional width of the stop member 101 on the side near the second intake port 106.

[0063] like Figure 3 The bottom of the stop member 101 is closer to the first suction port 105, and the top is closer to the second suction port 106. The cross-section of the stop member 101 gradually widens from the top to the bottom. The bottom of the stop member 101 is closer to the roller brush assembly 110 than the top. The bottom of the stop member 101 and the lower edge of the first suction port 105 form a longer suction channel, which can form a more stable airflow. The top of the stop member 101 is farther away from the roller brush assembly 110, which can prevent the flexible cleaning part 113 from pushing the movable part 102 away when there are no particles or debris.

[0064] As an optional implementation, the stop member 101 has a guide surface 1011 on the side facing the roller brush assembly 110; the outer surface of the roller brush assembly 110 has a flexible cleaning part 113, and when the roller brush assembly 110 rotates, the flexible cleaning part 113 contacts the guide surface 1011.

[0065] like Figure 3 The stop member 101 has a cross-section that is narrow at the top and wide at the bottom. A guide surface 1011 can be formed on the side facing the roller brush assembly 110. The guide surface 1011 can be arc-shaped, and the distance from the lower edge of the guide surface 1011 to the center of the roller brush is less than the distance from the upper edge of the guide surface 1011 to the center of the roller brush. This prevents the flexible cleaning part 113 from pushing the movable part 102 away when it passes through the second suction port 106. The movable part 102 will only be pushed away when large particles of debris pass by.

[0066] As an optional implementation, the end of the movable member 102 near the upper edge of the air inlet 104 is rotatably connected to the main body 100 of the device; the end of the movable member 102 near the stop member 101 can abut against the side of the stop member 101 facing into the cleaning air duct 103 to close the second suction port 106, or the end of the movable member 102 near the stop member 101 can deflect into the cleaning air duct 103 to open the second suction port 106.

[0067] Optionally, a torsion spring can be provided at the pivot of the connection between the movable part 102 and the main body 100 of the equipment to provide a pre-tightening force for closing the second suction port. When large particles push the movable part 102, the top of the movable part 102 rotates around the pivot, and the bottom moves away from the stop 101, opening the second suction port 106. When the external force disappears, the bottom of the movable part 102 re-abuts against the stop 101 under the action of the pre-tightening force, closing the second suction port 106. Alternatively, no torsion spring is provided at the pivot of the movable part 102. When no large particles pass through the second suction port 106, the movable part 102 closes the second suction port 106 by its own weight.

[0068] As an optional implementation, the movable member 102 is a flexible member. The first end of the flexible member abuts against and is fixed relative to the upper edge of the air inlet 104. The second end of the flexible member can abut against the side of the stop member 101 facing into the cleaning air duct 103 to close the second suction port 106. Alternatively, the second end of the flexible member can be deflected relative to the first end of the flexible member in a direction away from the roller brush assembly 110 to open the second suction port 106.

[0069] Optionally, the flexible component can be made of rubber, silicone, etc., and can be selected as needed. The flexible component can open the second suction port 106 by deformation or rotation to allow large particles of debris to pass through.

[0070] As an alternative implementation, the movable member 102 is movably disposed at the air inlet 104; the movable member 102 may cover the second suction port 106, or move relative to the roller brush assembly 110 into the cleaning air duct 103 to open the second suction port 106.

[0071] The cleaning device 10 also includes an elastic element that abuts against the movable element 102 and applies a force toward the roller brush assembly 110 to the movable element 102.

[0072] Optionally, the movable part 102 abuts against the elastic part, which can be a spring. The spring applies a force to the movable part 102 toward the roller brush assembly 110. When no large particles reach the second suction port 106, the upper end of the movable part 102 abuts against the upper end of the air inlet 104 and the lower end abuts against the stop member 101 under the action of the spring, and the second suction port 106 is closed by the movable part 102. When large particles reach the second suction port 106, the large particles push the movable part 102 to move into the cleaning air duct 103, and the second suction port 106 is opened at this time.

[0073] As an alternative implementation, when the movable member 102 blocks the second suction port 106, the lower edge of the movable member 102 is lower than the rotation axis of the roller brush assembly 110 in the height direction of the cleaning device 10.

[0074] Understandably, when the roller brush assembly 110 rolls, the flexible cleaning section 113 moves large particles of debris. When the flexible cleaning section 113 carrying large particles of debris is lower than the rotation axis of the roller brush assembly 110, the large particles of debris are more likely to accumulate at the end of the flexible cleaning section 113 away from the axis. When it is higher than the rotation axis of the roller brush assembly 110, if the rotation speed of the roller brush assembly 110 is insufficient, the large particles of debris may roll towards the end of the flexible cleaning section 113 near the axis under the action of gravity. Therefore, when the movable member 102 blocks the second suction port 106, in the height direction of the cleaning device 10, the lower edge of the movable member 102 is lower than the rotation axis of the roller brush assembly 110, which helps the large particles of debris to push the movable member 102 aside and enter the second suction port 106.

[0075] As an alternative implementation, at least a portion of the lower edge of the first suction port 105 extends below the roller brush assembly 110, and the air intake direction of the first suction port 105 is parallel to the horizontal direction, or is inclined downward relative to the horizontal direction towards the cleaning device 10.

[0076] It is understandable that the first suction port 105 formed by the lower edge of the air inlet 104 and the lower edge of the stop 101 is a flat suction port. When the angle between the flat suction port and the horizontal surface to be cleaned is greater than or equal to 0 degrees, it is more helpful for the flat suction port to suck up dust, hair and water stains from the surface to be cleaned.

[0077] The roller brush can be configured to contact, be press-fitted to, or have a gap with the first suction port 105, depending on the actual cleaning effect of the first suction port 105.

[0078] As an optional implementation, the first suction port 105 extends to the inner side below the roller brush assembly 110 and is provided with a recess 107, which is disposed adjacent to the lower edge of the stop member 101.

[0079] Understandably, the bottom of the recess 107 can be an arc-shaped surface to guide large particles smoothly across the first suction port 105 to the side of the stop member 101. Preferably, the tangent at the highest point of the arc-shaped surface can be tangent to the lowest point of the side of the stop member 101 near the roller brush assembly 110.

[0080] 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 sleeved on the outside of the roller brush shaft 111. The roller brush shaft 111 is rotatably connected to the device body 100. The circumferential sidewall of the roller brush body 112 is provided with a flexible cleaning part 113 integrally formed therewith.

[0081] Understandably, the roller brush shaft 111, acting as a transmission device, drives the roller brush body 112 to rotate. The flexible cleaning part 113 contacts the surface to be cleaned, cleaning the surface and lifting up dust, hair, and particulate debris. The flexible cleaning part 113 can be made of silicone, polyvinyl chloride, thermoplastic polyurethane, etc., and can be selected based on the cleaning effect.

[0082] As an optional implementation, the device body 100 has a roller brush cover 108, which is configured to form a roller brush groove that is open towards the lower part of the device body 100, and the roller brush assembly 110 is rotatably disposed in the roller brush groove; the edge of the roller brush cover 108 is connected to the upper edge of the air inlet 104.
