Abstract
Description
Technical Field
[0001] This application relates to the field of cleaning product technology, and more particularly to a roller and cleaning equipment. Background Technology
[0002] Vacuum cleaners, floor scrubbers, mite removers and other cleaning equipment are widely used for environmental cleaning in various indoor and outdoor scenarios. Different cleaning equipment maintains a clean and tidy living and working environment through various functions such as beating and vacuuming.
[0003] In related technologies, cleaning equipment typically uses a roller brush to pat soft surfaces to be cleaned, making it easier for dust, hair, and other debris on the surface and deep within the surface to be cleaned to detach from the surface. The dust, hair, and other debris are then sucked in through the air intake to clean the surface.
[0004] However, during the cleaning process, hair can easily get tangled in the roller brush, and hair on soft surfaces to be cleaned is not thoroughly cleaned. Utility Model Content
[0005] This application provides a roller and cleaning device to solve the technical problems of hair easily getting tangled in the roller brush during the current cleaning process, and hair on soft surfaces to be cleaned not being thoroughly cleaned.
[0006] In a first aspect, this application provides a roller for a cleaning device, wherein the roller is rotatably disposed on the cleaning device; the roller includes a cylinder and a plurality of rigid cleaning parts; the plurality of rigid cleaning parts are circumferentially spaced around the cylinder; each rigid cleaning part has at least one slapping structure, the slapping structure being disposed protruding from the surface of the cylinder; along the axial direction of the roller, the slapping structure of at least one rigid cleaning part is staggered with the slapping structures of at least a portion of other rigid cleaning parts.
[0007] The roller provided in this application beats and scrapes the surface to be cleaned by hard cleaning parts, while simultaneously sucking in dust, hair and other debris through a suction structure. Because the beating structures on different hard cleaning parts are arranged in an alternating manner, airflow can flow between the beating structures, which can prevent hair from getting tangled in the roller, while increasing airflow and improving the cleaning efficiency for hair.
[0008] As an alternative implementation, multiple rigid cleaning parts are integrally formed with the cylinder body; or, multiple rigid cleaning parts are detachably connected to the cylinder body.
[0009] With this design, multiple hard cleaning sections can be integrally molded with the cylinder body to increase structural stability, or they can be detachably connected to the cylinder body for easy replacement of worn parts.
[0010] As an alternative implementation, the striking structure has an arc-shaped surface that protrudes in a direction away from the rotation center of the cylinder.
[0011] This design, with its curved surface, makes the contact between the tapping structure and the surface to be cleaned smoother, thus dispersing the contact pressure.
[0012] As an optional implementation, the ratio of the cross-sectional profile length of the arcuate surface to the cross-sectional perimeter of the outer profile formed by the rotation of the roller is 40%-60%.
[0013] This design increases the contact area between the hard cleaning part and the surface to be cleaned, improving the cleaning effect, while ensuring the structural strength of the hard cleaning part and preventing it from breaking due to excessive narrowness.
[0014] As an alternative implementation, the dimensions of the striking structure remain unchanged from the bottom end near the center of rotation of the cylinder to the top end away from the center of rotation of the cylinder.
[0015] This design ensures the structural strength of the striking structure and prevents it from breaking under stress.
[0016] As an alternative implementation, the sum of the lengths of the tapping structures on each hard cleaning section is less than the axial length of the cylinder.
[0017] This design allows for ventilation openings in each hard cleaning section, increasing the ventilation area and thus improving cleaning efficiency.
[0018] As an alternative implementation, the hard cleaning part has a ventilation notch located at the end of the tapping structure along its length; when the tapping structure contacts the surface to be cleaned, the ventilation notch is configured to connect the radial sides of the roller.
[0019] This design increases the ventilation area through the ventilation gaps, improving cleaning efficiency while preventing hair from getting tangled in the rollers.
[0020] As an optional implementation, the plurality of hard cleaning sections include a first hard cleaning section having two tapping structures located at both ends of the first hard cleaning section, with a ventilation gap formed between the two tapping structures located at the middle of the roller axis; when the roller rotates, at least one other hard cleaning section's tapping structure covers the area opposite the ventilation gap to the surface to be cleaned.
[0021] This design, by covering the area opposite the ventilation opening and the surface to be cleaned with a tapping structure, prevents cleaning from being missed.
[0022] As an optional implementation, the plurality of hard cleaning sections also includes a second hard cleaning section; the second hard cleaning section has a single tapping structure located in the middle of the cylinder axial direction, and the two ends of the tapping structure form ventilation gaps between the two ends of the cylinder respectively; when the drum rotates, the two tapping structures of the first hard cleaning section respectively cover the areas of the two ventilation gaps of the second hard cleaning section opposite to the surface to be cleaned.
[0023] This configuration, where the patting structure of the first hard cleaning section covers the area opposite the two ventilation openings of the second hard cleaning section to the surface to be cleaned, prevents cleaning from being missed.
[0024] As an optional implementation, there are multiple first hard cleaning sections and multiple second hard cleaning sections, which are arranged alternately in the circumferential direction of the roller rotation.
[0025] This configuration, with the alternating arrangement of the first and second hard cleaning sections, ensures that the radial sides of the roller remain connected during its rotation.
[0026] As an alternative implementation, the length of the patting structure of the first hard cleaning part is greater than or equal to the length of the ventilation gap.
[0027] This design ensures that the patting structure of the first hard cleaning section can cover the cleaning areas missed by the ventilation gaps, thus improving cleaning efficiency.
[0028] As an optional implementation, the length of the rigid cleaning section matches the length of the cylinder; both ends of the rigid cleaning section are connected to both ends of the cylinder, and at least a portion of the rigid cleaning section along its length has a ventilation gap with the outer surface of the cylinder.
[0029] This design allows for a larger ventilation area through ventilation gaps, thereby improving cleaning efficiency.
[0030] Secondly, this application provides a cleaning device, which includes a device body and the aforementioned roller, with the roller rotatably mounted on the device body.
[0031] The cleaning equipment provided in this application can effectively clean hair from the surface to be cleaned using a roller, while preventing hair from getting tangled in the roller and ensuring normal operation of the equipment.
[0032] This application provides a roller for use in cleaning equipment, wherein the roller is rotatably mounted on the cleaning equipment; the roller includes a cylinder and a plurality of rigid cleaning sections; the plurality of rigid cleaning sections are circumferentially spaced around the cylinder; each rigid cleaning section has at least one slapping structure protruding from the surface of the cylinder; along the axial direction of the roller, the slapping structures of at least one rigid cleaning section are staggered with the slapping structures of at least some of the other rigid cleaning sections. The roller provided by this application can effectively remove hair fibers from the surface to be cleaned, while preventing hair fibers from entangled in the roller.

Therefore, they should not be construed as limitations on this application.
[0047] The terms "first," "second," and "third" (if any) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein.

[0049] 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.
[0050] Vacuum cleaners, floor scrubbers, mite removers and other cleaning equipment are widely used for environmental cleaning in various indoor and outdoor scenarios. Different cleaning equipment maintains a clean and tidy living and working environment through various functions such as beating and vacuuming.
[0051] In related technologies, cleaning equipment typically uses a roller brush to pat soft surfaces such as sofas and carpets, allowing dust, hair, and other debris from the surface and deep layers of the surface to be easily removed. The dust, hair, and other debris are then sucked in through the air intake to clean the surface.
[0052] However, the roller brush is prone to getting tangled in hair during rotation, which affects its cleaning function, and the hair on the soft surface to be cleaned is prone to sticking together, resulting in incomplete cleaning.
[0053] To address the aforementioned technical problems, this application provides a roller and a cleaning device. The roller uses a patting structure on its rigid cleaning section to pat the surface to be cleaned and sucks in debris through an air inlet. The patting structures on different rigid cleaning sections are arranged alternately, thereby creating a space for airflow on the side of the patting structure. When the patting structure contacts the surface to be cleaned, the airflow can enter the air inlet from the side of the patting structure. This avoids hair from getting tangled in the roller and improves suction efficiency, making it easier to suck in hair and resulting in a more thorough cleaning.
[0054] The following is an example illustrating the application scenarios of the floor brush device provided in the embodiments of this application.
[0055] The applicable product types provided in this application embodiment may include, but are not limited to, vacuum cleaners, mite removers, etc. Depending on the product type, the cleaning equipment provided in this application embodiment can be used to clean soft surfaces of various materials, such as sofas, carpets, etc. This application embodiment does not make specific limitations in this regard.
[0056] Figure 1 This is a schematic diagram of the structure of the cleaning equipment provided in the embodiments of this application; Figure 2 This is a schematic diagram of the structure of the roller provided in an embodiment of this application; Figure 3 for Figure 2 A schematic diagram of the AA cross-section; Figure 4 A schematic diagram of a partial cross-section of the roller provided in an embodiment of this application; Figure 5 A schematic diagram of a drum from a first perspective provided in an embodiment of this application; Figure 6 This is a schematic diagram of a second perspective view of a roller provided in an embodiment of this application.
[0057] Reference Figures 1 to 6 As shown, this application provides a roller 100 for cleaning equipment 10, and the roller 100 is rotatably disposed on the cleaning equipment 10; the roller 100 includes a cylinder 110 and a plurality of hard cleaning sections 120; the plurality of hard cleaning sections 120 are circumferentially spaced around the cylinder 110; each hard cleaning section 120 has at least one slapping structure 121, the slapping structure 121 protruding from the surface of the cylinder 110; along the axial direction of the roller 100, the slapping structure 121 of at least one hard cleaning section 120 is staggered with the slapping structures 121 of at least some other hard cleaning sections 120.
[0058] It should be noted that the cleaning device 10 also includes a main body 200, which has a roller cavity 210. The roller 100 is rotatably disposed in the roller cavity 210, and the roller cavity 210 is connected to the air intake 220. The air intake 220 can be connected to the air intake unit through the air intake channel. During cleaning, the motor drives the roller 100 to rotate, so that the beating structure 121 on the rigid cleaning part 120 arranged along the circumference of the roller 100 can alternately beat the surface to be cleaned, so that dust, hair and other debris on the surface to be cleaned can be thrown out. When the air intake unit is started, the air intake 220 generates negative pressure suction, and the airflow flows to the air intake 220. The thrown dust, hair and other debris are followed by the airflow into the air intake 220 and are finally collected in the dust cup inside the main body 200. In addition, the deep dust on the surface to be cleaned will also be detached from the surface to be cleaned during the beating process and sucked into the air intake 220, achieving deep cleaning.
[0059] It should be noted that, since each hard cleaning section 120 has one or more tapping structures 121, ventilation gaps 122 are formed between the tapping structures 121 and the end of the roller 100, as well as between the multiple tapping structures 121. These ventilation gaps 122 increase the ventilation area, thereby increasing the suction efficiency. Along the axial direction of the roller 100, the tapping structures 121 of at least one hard cleaning section 120 are staggered with the tapping structures 121 of at least some other hard cleaning sections 120, that is, the tapping structures 121 of at least one hard cleaning section 120 are staggered with the tapping structures 121 of at least some other hard cleaning sections 120. The axial projection of the roller 100 intersects with the axial projection of the tapping structure 121 of at least a portion of the hard cleaning section 120, and covers the entire axial length of the roller 100. The intersecting projections may have overlapping portions, so that when the roller 100 rotates, the cleaning missed areas caused by the ventilation gap 122 on each hard cleaning section 120 are covered by the cleaning range of at least one other hard cleaning section 120's tapping structure 121, achieving efficient cleaning while avoiding cleaning missed areas.
[0060] In some embodiments, multiple rigid cleaning parts 120 are integrally formed with the cylinder 110, and the rigid cleaning parts 120 and the cylinder 110 are an inseparable whole, so that when the roller 100 rotates, the rigid cleaning parts 120 will not loosen, make abnormal noises, or detach due to unstable connection, thereby increasing the structural stability of the roller 100.
[0061] In other embodiments, multiple hard cleaning parts 120 are detachably connected to the cylinder 110. For example, the cylinder 110 may be provided with a groove extending along the length of the cylinder 110, and the hard cleaning parts 120 are provided with a protrusion that matches the cross-sectional shape of the groove. The protrusion extends along the length of the hard cleaning parts 120. The hard cleaning parts 120 and the cylinder 110 can be detachably connected by inserting the protrusion into the groove. This connection method facilitates the replacement of worn hard cleaning parts 120 and facilitates the disassembly and cleaning of hard cleaning parts 120.
[0062] Reference Figure 4 As one possible implementation, the striking structure 121 has an arcuate surface 1211 that protrudes in a direction away from the rotation center of the cylinder 110.
[0063] It is understandable that the tapping structure 121 is made of a rigid material, and will not deform or will deform very little during contact with the surface to be cleaned. By designing the contact surface between the tapping structure 121 and the surface to be cleaned as a convex arc-shaped surface 1211, the contact process between the arc-shaped surface 1211 and the surface to be cleaned during rotation is smoother, the contact pressure of the arc-shaped surface 1211 can gradually increase, reducing tapping resistance. At the same time, the arc-shaped surface 1211 can increase the contact area with the surface to be cleaned, thereby improving cleaning efficiency.
[0064] As one possible implementation, the ratio of the cross-sectional profile length of the arc-shaped surface 1211 to the cross-sectional perimeter of the outer profile formed by the rotation of the roller 100 is 40%-60%.
[0065] It is understandable that the rotation of the roller 100 will drive the arc-shaped surface 1211 to rotate. When the arc-shaped surface 1211 rotates, it will form a cylindrical outer contour. By limiting the cross-sectional contour length of the arc-shaped surface 1211 to 40%-60% of the cross-sectional circumference of the outer contour, it can be ensured that the cross-sectional width of the slapping structure 121 is moderate. It will not be too narrow and easily break, nor will it be too wide and unable to achieve the slapping effect.
[0066] For example, the ratio of the cross-sectional profile length of the arc-shaped surface 1211 to the cross-sectional perimeter of the outer profile formed by the rotation of the roller 100 can be 40%, 45%, 50%, 55%, 60%, etc., and this application embodiment does not make specific limitations.
[0067] As one possible implementation, the dimensions of the striking structure 121 remain unchanged from the bottom end near the rotation center of the cylinder 110 to the top end away from the rotation center of the cylinder 110.
[0068] It is understandable that the two sides of the cross-section of the striking structure 121 are parallel to each other, that is, from the bottom end near the rotation center of the cylinder 110 to the top end away from the rotation center of the cylinder 110, the distance between the two sides of the striking structure 121 is equal everywhere. This arrangement can ensure the striking effect while ensuring the strength of the striking structure 121 and preventing the striking structure 121 from breaking under stress.
[0069] In some embodiments, the side of the striking structure 121 near the cylinder 110 can be an arc-shaped bottom surface. The arc-shaped bottom surface is curved away from the cylinder 110, that is, the arc-shaped bottom surface is recessed. The recessed arc-shaped bottom surface can disperse stress during the striking process of the striking structure 121, and avoid stress concentration in local areas.
[0070] As one possible implementation, the sum of the lengths of the tapping structures 121 on each hard cleaning section 120 is less than the axial length of the cylinder 110.
[0071] It is understandable that, since the hard cleaning section 120 extends axially along the cylinder 110 and the length of the hard cleaning section 120 matches the length of the cylinder 110, and the sum of the lengths of the tapping structures 121 on each hard cleaning section 120 is less than the axial length of the cylinder 110, each hard cleaning section 120 generates a ventilation gap 122, thereby increasing the ventilation area.
[0072] As one possible implementation, the hard cleaning section 120 has a ventilation notch 122 located at the end of the tapping structure 121 in the longitudinal direction; when the tapping structure 121 contacts the surface to be cleaned, the ventilation notch 122 is configured to connect the radial sides of the roller 100.
[0073] It is understandable that the ventilation gap 122 is located at the end of the beat structure 121 along its length, that is, between two adjacent beat structures 121 of the same hard cleaning part 120, and between the connection end of the beat structure 121 and the cylinder 110. When the beat structure 121 contacts the surface to be cleaned, the ventilation gap 122 at the end of the beat structure 121 can connect the radial sides of the roller 100, that is, connect the air intake 220 and the external environment. When the air intake 220 draws air, the airflow can pass through the sides and top of the roller 100 on the one hand, and through the ventilation gap 122 on the other hand, which improves the absorption efficiency of hair and other debris. In addition, the ventilation gap 122 can absorb the hair fibers wrapped around the roller 100, preventing the hair fibers wrapped around the roller 100 from accumulating and affecting the normal rotation of the roller 100.
[0074] It should be noted that the surface of the ventilation notch 122 is lower than the arc-shaped surface 1211 of the tapping structure 121 but higher than the surface of the cylinder 110. The height difference between the surface of the ventilation notch 122 and the arc-shaped surface 1211 of the tapping structure 121 can be determined according to the usage scenario, and this embodiment does not impose a specific limitation. When the roller 100 cleans the surface to be cleaned, since the soft surface to be cleaned is uneven, the solid structure at the surface of the ventilation notch 122 can also scrape and tap the raised surface to be cleaned, further improving the cleaning efficiency.
[0075] Reference Figure 5 and Figure 6 , combined Figures 1 to 4As one possible implementation, the plurality of hard cleaning sections 120 may include a first hard cleaning section 123, the first hard cleaning section 123 having two tapping structures 121 located at both ends of the first hard cleaning section 123, and a ventilation gap 122 formed between the two tapping structures 121, the ventilation gap 122 being located at the middle of the roller 100 axial direction; when the roller 100 rotates, the tapping structure 121 of at least one other hard cleaning section 120 covers the area of the ventilation gap 122 opposite to the surface to be cleaned.
[0076] As one possible implementation, the multiple hard cleaning sections 120 may also include a second hard cleaning section 124; the second hard cleaning section 124 has a single tapping structure 121, the single tapping structure 121 is located in the middle of the cylinder 110 in the axial direction, and the two ends of the tapping structure 121 form ventilation gaps 122 between the two ends of the cylinder 110 respectively; when the roller 100 rotates, the two tapping structures 121 of the first hard cleaning section 123 respectively cover the areas of the two ventilation gaps 122 of the second hard cleaning section 124 opposite to the surface to be cleaned.
[0077] As one possible implementation, there are multiple first hard cleaning parts 123 and multiple second hard cleaning parts 124, and the multiple first hard cleaning parts 123 and multiple second hard cleaning parts 124 are arranged alternately in the rotational circumference of the roller 100.
[0078] In some embodiments, only one of the first hard cleaning part 123 or the second hard cleaning part 124 is in contact with the surface to be cleaned at any given time. When the roller 100 rotates, the first hard cleaning part 123 and the second hard cleaning part 124 alternately contact the surface to be cleaned. By adjusting the rotation speed of the roller 100, the cleaning range of the slapping structure 121 of the first hard cleaning part 123 can cover the cleaning missed area of the ventilation gap 122 of the second hard cleaning part 124, and the cleaning range of the slapping structure 121 of the second hard cleaning part 124 can cover the cleaning missed area of the ventilation gap 122 of the first hard cleaning part 123.
[0079] In other embodiments, the first hard cleaning part 123 and the second hard cleaning part 124 can simultaneously contact the surface to be cleaned. Along the cleaning direction of the cleaning device 10, the first hard cleaning part 123 and the second hard cleaning part 124 are alternately located on the front side. The ventilation opening 122 of the first hard cleaning part 123 and the second hard cleaning part 124 and the gap between the first hard cleaning part 123 and the second hard cleaning part 124 form a channel for airflow, so that air from the outside environment can enter the air intake 220.
[0080] As one possible implementation, the length of the tapping structure 121 of the first hard cleaning section 123 is greater than or equal to the length of the ventilation gap 122.
[0081] Understandably, the length of the tapping structure 121 is greater than or equal to the length of the ventilation gap 122, so that the tapping structure 121 can completely cover the area of the ventilation gap 122 when it rotates. This ensures that the tapping structure 121 will not miss the area to be cleaned corresponding to the ventilation gap 122 during the cleaning process. In addition, the longer tapping structure 121 can penetrate deeper into the area around the ventilation gap 122, reducing cleaning dead corners.
[0082] As one possible implementation, the length of the rigid cleaning section 120 matches the length of the cylinder 110; both ends of the rigid cleaning section 120 are connected to both ends of the cylinder 110 respectively, and at least a portion of the rigid cleaning section 120 in the length direction has a ventilation gap 130 between it and the outer surface of the cylinder 110.
[0083] It should be noted that the surface of the cylinder 110 has multiple support portions 140 protruding from the surface of the cylinder 110. The multiple support portions 140 are spaced apart circumferentially along the cylinder 110, and the two ends of the support portions 140 are respectively connected to the surface of the cylinder 110 and the bottom of the hard cleaning portion 120. The two ends of the hard cleaning portion 120 are connected to the two ends of the cylinder 110, and the bottom is connected to the support portions 140, thereby forming a stable support structure.
[0084] It should be noted that the support part 140 can be arranged parallel to the circumference of the cylinder 110, or it can be arranged alternately along the circumference of the cylinder 110.
[0085] For example, multiple support portions 140 are disposed in the middle of the cylinder 110 in the axial direction, and the support portions 140 divide the ventilation gap 130 between the lower surface of the hard cleaning portion 120 and the outer surface of the cylinder 110 into two parts.
[0086] For example, there are two support portions 140 connected to the first hard cleaning part 123, and the two support portions 140 are respectively disposed at both ends of the cylinder 110, with the ventilation gap 130 located between the two support portions 140; there is one support portion 140 connected to the second hard cleaning part 124, and the support portion 140 is disposed in the middle of the cylinder 110 in the axial direction, and the support portion 140 divides the ventilation gap 130 between the lower surface of the second hard cleaning part 124 and the outer surface of the cylinder 110 into two parts.
[0087] It should be noted that the height of the ventilation gap 130 is the same as the height of the support part 140, and the height of the ventilation gap 130 is 1%-100% of the diameter of the cylinder 110. When the air intake 220 draws air, the airflow can flow through the ventilation gap 130, which further increases the ventilation area and improves the cleaning efficiency.
[0088] For example, the ratio of the height of the ventilation gap 130 to the diameter of the cylinder 110 can be 1%, 10%, 20%, 50%, 99%, 100%, etc., and this application embodiment does not make specific limitations.
[0089] This application also provides a cleaning device 10, which includes a device body 200 and the aforementioned roller 100, with the roller 100 rotatably disposed on the device body 200.
[0090] It should be noted that the roller 100 has a first fixed seat 150 and a second fixed seat 160 at both ends. The second fixed seat 160 is provided with a shaft hole. One end of the roller cavity 210 is provided with a shaft, which is inserted into the shaft hole and electrically connected to the motor, so as to drive the roller 100 to rotate. The first fixed seat 150 has a snap-fit structure. When the roller 100 is installed, the roller 100 is inserted into the roller cavity 210 and snapped onto the other end of the roller cavity 210 relative to the shaft by the snap-fit mechanism, so as to fix the roller 100.
[0091] This application provides a roller 100 for use in a cleaning device 10, wherein the roller 100 is rotatably disposed on the cleaning device 10. The roller 100 includes a cylindrical body 110 and a plurality of rigid cleaning sections 120.
