Description

Technical Field

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

[0002] Cleaning devices such as mite removers, vacuum cleaners, and robotic vacuum cleaners are commonly used in households. Vacuum cleaners and robotic vacuum cleaners can clean floors, while mite removers can remove dust and worms from surfaces such as mattresses and leather.

[0003] In related technologies, cleaning equipment typically includes a housing and a fan unit housed within the housing. The airflow generated by the fan unit creates suction at the air inlet of the housing. A roller brush chamber can be positioned corresponding to the air inlet, and a roller brush is housed within the roller brush chamber. A cover plate is placed on the side of the roller brush chamber facing the surface to be cleaned, and the cover plate has an opening that allows the roller brush to contact the surface for cleaning. Multiple baffles are horizontally arranged across the opening of the cover plate to prevent sheets, blankets, and other items from being sucked into the roller brush chamber.

[0004] However, during the cleaning process, the baffles on the cover plate of the current cleaning equipment can prevent the roller brush from contacting the surface to be cleaned. Therefore, the cleaning parts on the roller brush need to be grooved to avoid the baffles. However, this causes hair fibers to get tangled on the roller brush and cannot be sucked into the equipment, making them difficult to clean. Utility Model Content

[0005] This application provides a cleaning device to solve the technical problem that in current cleaning devices, the cleaning components on the roller brush have grooves to avoid the baffles, causing hair fibers to become entangled on the roller brush and unable to be sucked into the device, making them difficult to clean.

[0006] This application provides a cleaning device, which includes a roller brush assembly, a housing, and a cover plate. The cover plate is connected to the housing and surrounds the roller brush cavity, and the roller brush assembly is rotatably disposed within the roller brush cavity.

[0007] The cover plate has an opening, the roller brush assembly is opposite the opening, and the opening is configured to form an empty cleaning area connecting the inner and outer sides of the roller brush cavity; the edge of the opening is provided with a support, which protrudes from the surface of the cover plate.

[0008] The cleaning device provided in this application does not have a transverse baffle structure on the opening of the cover plate. Instead, the opening is left to form a complete area, namely an empty cleaning area. At the same time, the outer edge support abuts against the surface to be cleaned to provide support. In this way, the roller brush assembly can have sufficient interference with the surface to be cleaned during the cleaning process. The roller brush assembly contacts and pats the surface to be cleaned as a whole without the need for grooves to avoid it. This has a good cleaning effect while preventing hair from getting tangled on the roller brush assembly.

[0009] As an alternative implementation, the cover plate has a first plane on the side facing the outside of the roller brush cavity, and the support portion protrudes outward from the first plane relative to the outside of the roller brush cavity.

[0010] With this design, the support part can come into contact with the surface to be cleaned during the cleaning process, providing support and allowing the roller brush to tap the parts to be cleaned when it rotates, resulting in a better cleaning effect.

[0011] As an optional implementation, the width of the vacant cleaning area along the first direction is smaller than the maximum outer diameter of the roller brush assembly, wherein the first direction is the cleaning direction of the cleaning device.

[0012] This design prevents sheets, blankets, and other bedding from being sucked into the roller brush cavity and causing blockages during the cleaning process.

[0013] As an alternative implementation, the axial length of the roller brush assembly matches the axial length of the vacant cleaning area along a second direction, which is perpendicular to the first direction.

[0014] This design allows the rolling brush assembly to contact and pat the surface to be cleaned along the entire axial direction, maximizing the cleaning coverage area. There is no need for grooves to avoid any gaps along the length of the brush assembly, preventing hair fibers from getting tangled and difficult to clean.

[0015] As an optional implementation, the support may include a plurality of support ribs, which are spaced apart at the edge of the opening, and ventilation grooves are formed between adjacent support ribs.

[0016] This design ensures that airflow can pass through the opening in the cover plate to continuously create negative pressure suction for cleaning, resulting in a stable cleaning effect.

[0017] As an optional implementation, the multiple support ribs may include multiple first support ribs and multiple second support ribs, with the multiple first support ribs spaced apart on the front side of the opening along the cleaning direction of the cleaning device; and the multiple second support ribs spaced apart on the rear side of the opening along the cleaning direction of the cleaning device.

[0018] With this design, support structures are formed on both sides of the opening, ensuring that the cleaning device can effectively clean the surface by patting the surface being cleaned, whether it is pushed forward or pulled backward.

[0019] As an optional implementation, the first support rib is vertically disposed relative to the surface of the cover plate; and / or;

[0020] The second support rib is inclined inward relative to the surface of the cover plate.

[0021] This design prevents bed sheets and blankets from being sucked into the roller brush cavity, thus preventing the suction channel from being blocked and hindering cleaning.

[0022] As an optional implementation, the distance between the rotation axis of the roller brush assembly and the first support rib is greater than the distance between the roller brush assembly and the second support rib.

[0023] This design better prevents bed sheets and blankets from being pulled backward and sucked into the roller brush cavity when the cleaning equipment moves forward to clean. At the same time, the roller brush assembly can bring dust and hair closer to the internal air intake when it pulls them backward, thus achieving higher cleaning efficiency.

[0024] As an alternative implementation, the width of the support rib gradually decreases along its protruding direction.

[0025] This design can improve the structural strength of the support ribs while increasing the ventilation area between the support ribs, thus ensuring good air intake efficiency.

[0026] As an alternative implementation, the support is provided on the front and rear sides of the empty cleaning area along the cleaning direction of the cleaning equipment, and part of the structure of the support extends to both ends of the empty cleaning area perpendicular to the cleaning direction.

[0027] With this setup, there can also be support structures at both ends of the roller brush assembly to prevent sheets and blankets from being sucked into the roller brush cavity from both ends of the empty cleaning area.

[0028] The cleaning device provided in this application includes a roller brush assembly, a housing, and a cover plate. The cover plate is connected to the housing and surrounds the roller brush cavity. The roller brush assembly is rotatably disposed within the roller brush cavity. The cover plate has an opening, and the roller brush assembly is opposite to the opening. The opening is configured to form an empty cleaning area connecting the inner and outer sides of the roller brush cavity. A support portion is provided at the edge of the opening, protruding from the surface of the cover plate. In this way, the roller brush assembly can have sufficient interference with the surface to be cleaned during the cleaning process. The roller brush assembly makes a single contact with the surface to be cleaned, without the need for grooves to avoid overlap, achieving a good cleaning effect while preventing hair from getting tangled on the roller brush assembly.

[0039] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0040] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] Cleaning equipment typically includes a housing and a fan unit housed within it. The fan unit generates airflow that creates suction at the intake vent in the housing. A roller brush chamber is positioned corresponding to the intake vent, housing a roller brush. This brush rolls across the surface being cleaned, picking up dust and hair, which are then drawn into the equipment by the suction. A cover plate with an opening allows the roller brush to contact the surface for cleaning. Multiple ribs run across the opening of the cover plate to prevent sheets, blankets, and other items from being sucked into the roller brush chamber.

[0045] However, during the cleaning process of current cleaning equipment, the baffles on the cover plate can prevent the roller brush from contacting the surface to be cleaned. Therefore, the cleaning components on the roller brush need to be grooved to avoid the baffles. However, this causes hair fibers to get tangled on the roller brush and cannot be sucked into the equipment. As the roller brush rolls, the tangled hair gets more and more tightly wrapped in the grooves on the roller brush and cannot be sucked away. This will also affect the cleaning effect of the roller brush and make cleaning the roller brush time-consuming and laborious.

[0046] To address the aforementioned technical problems, this application provides a cleaning device. Through the structural design of the opening in the top cover of the cleaning device, the opening of the roller brush has a relatively larger and more complete cleaning area, avoiding the separation of the cleaning area of ​​the roller brush. This eliminates the need to groove the roller brush, allowing the roller brush to completely contact the cleaning structure with the surface to be cleaned, reducing the amount of hair tangled on the roller brush, improving cleaning efficiency, and making it easier to clean the roller brush after cleaning.

[0047] The following is an example illustrating the application scenarios of the cleaning equipment provided in the embodiments of this application.

[0048] 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, mite removers, vacuum cleaners, 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, clothes, bedding, sofas, furniture, etc. This application embodiment does not make any specific limitations on this.

[0049] Figure 1 A schematic diagram showing the cleaning device provided in this application facing the surface to be cleaned; Figure 2 A cross-sectional view of the roller brush assembly and cover plate mating in a cleaning device provided in an embodiment of this application; Figure 3 This is a schematic diagram of the structure of the cover plate in the cleaning equipment provided in the embodiments of this application; Figure 4 This is a side view of the cover plate in the cleaning equipment provided in an embodiment of this application.

[0050] See Figures 1 to 4 As shown, this application provides a cleaning device 10, which includes a roller brush assembly 100, a housing and a cover plate 200. The cover plate 200 is connected to the housing and surrounds the roller brush cavity 11. The roller brush assembly 100 is rotatably disposed in the roller brush cavity 11.

[0051] The cover plate 200 has an opening 201, and the roller brush assembly 100 is opposite to the opening 201. The opening 201 is configured to form an empty cleaning area 202 that connects the inner and outer sides of the roller brush cavity 11. The cover plate 200 is located at the bottom of the cleaning device 10, and the opening 201 on the cover plate 200 faces the surface to be cleaned.

[0052] Understandably, when the cleaning device 10 is performing a cleaning operation, the side of the cleaning device 10 connected to the roller brush assembly 100 faces the surface to be cleaned, that is, the empty cleaning area 202 is opposite to the surface to be cleaned, and the roller brush assembly 100 can contact the surface to be cleaned within the empty cleaning area 202. As the cleaning device 10 moves, the roller brush assembly 100 rolls on the surface to be cleaned, and the roller brush assembly 100 can pick up dust, hair fibers and other debris on the surface to be cleaned, making it easier for dust, hair fibers and other debris to be sucked into the cleaning device 10.

[0053] In some embodiments, the edge of the opening 201 is provided with a support portion 210, which protrudes from the surface of the cover plate 200. The protruding direction of the support portion 210 faces the outside of the roller brush cavity 11, and the support portion 210 abuts against the surface to be cleaned when the cleaning device 10 contacts the surface to be cleaned.

[0054] Since the support part 210 is located at the edge of the opening 201, the empty cleaning area 202 can be formed by the edge of the support part 210. During the cleaning process, the roller brush assembly 100 can partially contact the surface to be cleaned through the empty cleaning area 202 to complete the cleaning operation. The support part 210 plays a restrictive and blocking role, preventing the sheets and blankets from being sucked into the roller brush cavity 11 when cleaning the bed surface and bedding.

[0055] For example, vacant cleaning area 202 is Figure 1 The area enclosed by the dashed frame.

[0056] It should be noted that in the cleaning device 10 provided in this application embodiment, the cover plate 200 opening 201 does not have a transverse baffle structure. Instead, the opening 201 is retained to form a complete area, namely the empty cleaning area 202. At the same time, the outer edge support 210 abuts against the surface to be cleaned to provide support. In this way, the roller brush assembly 100 can have sufficient interference with the surface to be cleaned during the cleaning process. The roller brush assembly 100 contacts and pats the surface to be cleaned with an integral structure without the need for grooves to avoid it. This has a good cleaning effect while preventing hair from getting tangled on the roller brush assembly 100.

[0057] The axial direction of the roller brush assembly 100 is defined as the X direction, and the radial direction of the roller brush assembly 100 is defined as the Y direction. The Y direction is perpendicular to the X direction, and the cleaning device 10 can move along the Y direction during the cleaning operation.

[0058] The specific structure of the support part 210 will be described in detail below.

[0059] Please continue to refer to Figures 1 to 4In one possible implementation, the cover plate 200 has a first plane 203 on the side facing the outside of the roller brush cavity 11, and the support portion 210 protrudes outward from the first plane 203 relative to the outside of the roller brush cavity 11. In this way, during the cleaning process, the support portion 210 can abut against the surface to be cleaned to provide support, so that the roller brush can tap the part to be cleaned when it rotates, resulting in a better cleaning effect.

[0060] Understandably, in the empty cleaning area 202, since there is a support 210 on the periphery that abuts against the surface to be cleaned, when cleaning soft surfaces such as bed surfaces, the support 210 can locally squeeze and deform the surface to be cleaned, so that the roller brush assembly 100 is closer to the surface to be cleaned, ensuring that there is sufficient interference between the roller brush assembly 100 and the surface to be cleaned. In this way, the roller brush assembly 100 has a better cleaning effect on the surface to be cleaned when it rotates.

[0061] In some embodiments, the width of the vacant cleaning area 202 along a first direction is smaller than the maximum outer diameter of the roller brush assembly 100, wherein the first direction is the cleaning direction of the cleaning device 10. Projected perpendicular to the outlet direction of the cover plate 200, a portion of the projected area of ​​the roller brush assembly 100 is within the vacant cleaning area 202, while a portion is outside the vacant cleaning area 202. This prevents sheets, blankets, and other items from being sucked into the roller brush cavity 11 and causing blockage during the cleaning process.

[0062] It is understood that the first direction is the Y direction, the outer contour cross-section of the roller brush assembly 100 is circular when it rotates, and the outer cleaning structure of the roller brush assembly 100 can pass through the empty cleaning area 202 during rotation, thereby contacting the surface to be cleaned.

[0063] For example, the roller brush cavity 11 may be provided with an air inlet, which can generate negative pressure suction, so that the dust and hair fibers carried by the roller brush assembly 100 are sucked from the roller brush cavity 11 into the air inlet. During the process of airflow being drawn in through the air inlet, air passes through the empty cleaning area 202 and enters the roller brush cavity 11. At least part of the structure of the support 210 can guide the airflow and improve the smoothness of airflow.

[0064] In some embodiments, the axial length of the roller brush assembly 100 matches the axial length of the vacant cleaning area 202 along a second direction, which is perpendicular to the first direction. The second direction is the X direction, and the axial length of the roller brush assembly 100 is approximately or equal to the length of the controlled cleaning area.

[0065] It is understandable that the length of the empty cleaning area 202 matches the length of the roller brush assembly 100, while the width is smaller than the maximum radial diameter of the roller brush assembly 100. On the one hand, the support part 210 restricts the suction of sheets, quilts, etc. into the roller brush cavity 11. On the other hand, it allows the rolling roller brush assembly 100 to contact and pat the surface to be cleaned along the entire axial direction, maximizing the cleaning coverage area. There is no need for grooves to avoid any position along the length of the roller brush assembly 100, so as to prevent hair fibers from getting tangled and difficult to clean.

[0066] In one possible implementation, the support portion 210 may include a plurality of support ribs 211, which are spaced apart at the edge of the opening 201, and ventilation grooves are formed between adjacent support ribs 211. Air outside the roller brush cavity 11 can pass through the ventilation grooves and enter the roller brush cavity 11 under the action of negative pressure suction.

[0067] Understandably, the support 210 can support the surface to be cleaned so that the roller brush assembly 100 can contact the surface to be cleaned through the empty cleaning area 202. On the other hand, by using the ventilation slot, it can ensure that the airflow can pass through the opening 201 of the cover plate 200 to continuously form negative pressure suction for cleaning, which has a stable cleaning effect.

[0068] As an optional implementation, the plurality of support ribs 211 may include a plurality of first support ribs 211a and a plurality of second support ribs 211b, with the plurality of first support ribs 211a spaced apart on the front side of the opening 201 along the cleaning direction of the cleaning device 10. The plurality of second support ribs 211b spaced apart on the rear side of the opening 201 along the cleaning direction of the cleaning device 10.

[0069] It is understandable that by setting a first support rib 211a and a second support rib 211b on both sides of the opening 201 along the X direction, a support structure is formed on both sides of the opening 201. Whether the cleaning device 10 is pushed forward or pulled backward for cleaning, it can ensure that the roller brush assembly 100 can pat the surface to be cleaned and achieve a good cleaning effect.

[0070] For example, a plurality of first support ribs 211a are arranged along the X direction from one end of the opening 201 to the other end. A plurality of second support ribs 211b are arranged along the X direction from one end of the opening 201 to the other end. The specific number of first support ribs 211a and second support ribs 211b is not limited in the embodiments of this application.

[0071] For example, the air intake is located on the rear side of the roller brush within the roller brush cavity 11 along the cleaning direction of the cleaning device 10. The first support rib 211a is located on the front side of the opening 201 along the cleaning direction of the cleaning device 10, that is, the first support rib 211a is located on the side of the opening 201 away from the air intake, and the second support rib 211b is located on the side of the opening 201 closer to the air intake. During the cleaning operation, the airflow in front of the cleaning device 10 can enter the roller brush cavity 11 through the ventilation groove formed by the first support rib 211a, while the airflow on the rear side can enter the roller brush cavity 11 through the ventilation groove formed by the second support rib 211b.

[0072] It should be noted that, since the suction port of the second support rib is located on the same side of the roller brush cavity 11, when the airflow carrying dust and hair enters the roller brush cavity 11 from the opening 201 along the rear side of the roller brush assembly 100, the second support rib 211b can guide the airflow.

[0073] In some embodiments, the first support rib 211a is vertically disposed relative to the surface of the cover plate 200, that is, the first support rib 211a protrudes vertically outward from the surface of the cover plate 200 toward the outside of the brush cavity 11. For example, one side boundary of the empty cleaning area 202 formed by the first support rib 211a is flush with the side edge of the opening 201.

[0074] It is understandable that the suction force on the side of the roller brush cavity 11 where the first support rib 211a is set is weaker than that on the side where the second support rib 211b is set. Setting the first support rib 211a vertically can make full use of the area of ​​the opening 201, so as to ensure that the control cleaning area has a sufficiently large area so that the roller brush assembly 100 can contact the surface to be cleaned, while the front side has a high air intake efficiency.

[0075] In some embodiments, the second support rib 211b is inclined toward the opening 201 relative to the surface of the cover plate 200. This prevents bed sheets and blankets from being sucked into the roller brush cavity 11, thus preventing the suction channel from being blocked and hindering cleaning.

[0076] It is understandable that, as shown in the attached figure, during the cleaning process when the cleaning device 10 moves forward, the roller brush assembly 100 rotates clockwise. The dust and hair picked up by the roller brush assembly 100 after contacting the surface to be cleaned will be carried towards the air intake on the rear side of the roller brush assembly 100 along the rotation direction of the roller brush assembly 100. During this process, the airflow formed by the negative pressure of the air intake will suck the dust and hair into the device.

[0077] For example, the inclination angle of the second support rib 211b relative to the vertical direction can be 5°-85°, including but not limited to 5°, 10°, 30°, 45°, 60°, 80°, 85°, etc., where the vertical direction refers to the direction perpendicular to the XY plane.

[0078] In some embodiments, the distance between the rotation axis of the roller brush assembly 100 and the first support rib 211a is greater than the distance between the roller brush assembly 100 and the second support rib 211b. The axis of the roller brush assembly 100 is closer to the rear side of the opening 201 and farther from the front side of the opening 201.

[0079] Understandably, the air intake is located at the rear of the roller brush assembly 100. The rear-side arrangement of the roller brush assembly 100 better prevents bed sheets and blankets from being lifted backward and sucked into the roller brush cavity 11 when the cleaning device 10 moves forward to clean. At the same time, the roller brush assembly 100 can bring dust and hair closer to the internal air intake when it lifts them backward, thus achieving higher cleaning efficiency.

[0080] For example, the width of the support rib 211 gradually decreases along its protruding direction, which can improve the structural strength of the support rib 211 while increasing the ventilation area between the support ribs 211 and ensuring good air intake efficiency.

[0081] For example, the top of the support rib 211 facing the surface to be cleaned has a rounded chamfer structure, so that the position where the support rib 211 contacts the surface to be cleaned has a rounded or smooth surface, avoiding sharp chamfer structures. Since the support rib 211 will contact the surface to be cleaned during the cleaning process, the structure of the support rib 211 can avoid damaging the sheets, quilts and other surfaces to be cleaned.

[0082] As an optional implementation, the support portion 210 is provided on the front and rear sides of the empty cleaning area 202 along the cleaning direction of the cleaning device 10, and part of the structure of the support portion 210 extends to both ends of the empty cleaning area 202 perpendicular to the cleaning direction.

[0083] Understandably, the support portion 210 may also have a support structure at both ends of the roller brush assembly 100 along the X direction to prevent bed sheets and blankets from being sucked into the roller brush cavity 11 from both ends of the empty cleaning area 202.

[0084] It should be noted that the support 210 and the cover plate 200 can be integrally molded parts, and the material can be plastic or metal, or plastic-coated metal. This application embodiment does not specifically limit this.

[0085] The specific structure of the roller brush assembly 100 is described in detail below.

[0086] Please refer to Figures 1 to 4 As an optional implementation, the roller brush assembly 100 may include a roller 110 and a flexible cleaning element 120, the flexible cleaning element 120 being connected to the surface of the roller 110. When the cleaning device 10 performs a cleaning operation, the flexible cleaning element 120 can tap the surface to be cleaned as the roller 110 rotates.

[0087] For example, the flexible cleaning component 120 can be an adhesive strip or a brush, etc., and this application embodiment does not specifically limit it.

[0088] The cleaning device provided in this application includes a roller brush assembly, a housing, and a cover plate. The cover plate is connected to the housing and surrounds the roller brush cavity. The roller brush assembly is rotatably disposed within the roller brush cavity. The cover plate has an opening, and the roller brush assembly is opposite to the opening. The opening is configured to form an empty cleaning area connecting the inner and outer sides of the roller brush cavity. A support portion is provided at the edge of the opening, protruding from the surface of the cover plate. In this way, the roller brush assembly can have sufficient interference with the surface to be cleaned during the cleaning process. The roller brush assembly contacts and pats the surface to be cleaned as a whole without the need for grooves to avoid it, achieving a good cleaning effect while preventing hair from getting tangled on the roller brush assembly.

[0089] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. 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. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
