Description

Technical Field

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

[0002] Cleaning equipment such as mite removers, vacuum cleaners, floor scrubbers, and robotic vacuum cleaners are widely used for cleaning home environments.

[0003] In related technologies, cleaning equipment typically includes a roller brush with multiple scraping strips arranged circumferentially. During the cleaning process, a motor drives the roller brush to rotate, causing it to roll along the surface being cleaned. This results in the scraping strips continuously scraping or slapping the surface, thereby lifting dust, hair fibers, and other debris adhering to it. The cleaning equipment also features an air intake, positioned opposite the roller brush. The negative pressure airflow created by the air intake draws the dust and hair into the cleaning equipment.

[0004] However, during the cleaning process of current cleaning equipment, the hair tends to get tangled more and more tightly when the roller brush rotates, affecting the normal rotation of the roller brush. Utility Model Content

[0005] This application provides a floor brush device and cleaning equipment to solve the technical problem that in the current cleaning equipment, hair tends to get tangled more and more tightly when the roller brush rotates, affecting the normal rotation of the roller brush.

[0006] In a first aspect, this application provides a floor brush device, including a housing and a roller brush assembly, the housing having a roller brush cavity, and the roller brush assembly being rotatably disposed in the roller brush cavity.

[0007] The roller brush assembly includes a roller brush body and multiple flexible components. The multiple flexible components are connected to the roller brush body and are spaced apart on the periphery of the roller brush body; at least two flexible components have different height dimensions along the radial direction of the roller brush body.

[0008] The floor brush device provided in this application includes a roller brush assembly, which includes a roller brush body and a plurality of flexible members spaced apart around the roller brush body. When the roller brush body rotates, it drives the plurality of flexible members to continuously pat the ground to clean the surface to be cleaned. At least two of the flexible members have different height dimensions along the radial direction of the roller brush body, so that the outline edges of the plurality of flexible members are non-circular. In this way, the hair carried by the flexible members is less likely to get tangled on the roller brush assembly, and the hair is in a fluffy state and is more easily sucked into the floor brush device.

[0009] As an alternative implementation, in the circumferential direction of the roller brush body, the height dimensions of two adjacent flexible elements along the radial direction of the roller brush body are different.

[0010] This design causes the contour edge of the roller brush component to undulate continuously, preventing the hair from getting tangled more and more tightly.

[0011] As an optional implementation, the plurality of flexible elements includes a first flexible element and a second flexible element; the height dimension of the first flexible element along the radial direction of the brush body is greater than the height dimension of the second flexible element along the radial direction of the brush body.

[0012] When the floor brush device cleans the surface to be cleaned and the roller brush assembly rotates, at least the first flexible element comes into contact with the surface to be cleaned and undergoes elastic deformation.

[0013] This configuration, by setting the height dimensions of the first and second flexible components differently, ensures that the outline edge of the roller brush assembly is non-circular, while also ensuring that at least one flexible component can contact and tap the surface to be cleaned.

[0014] As an optional implementation, there are multiple first flexible members and multiple second flexible members; the multiple first flexible members and multiple second flexible members are alternately spaced in the circumferential direction of the brush body.

[0015] This configuration, by alternating between first and second flexible components of different sizes, causes the contour edge of the roller brush assembly to undulate continuously, preventing the hair from becoming increasingly tangled.

[0016] As an optional implementation, the floor brush device also includes a roller, which is rotatably connected to the housing; when the first flexible member is directly below the axis of the main body of the roller brush, the lower edge of the first flexible member in its natural state is lower than the horizontal tangent of the lower edge of the roller, and the vertical distance between the lower edge of the first flexible member in its natural state and the horizontal tangent of the lower edge of the roller is greater than 0 mm and less than or equal to 1 mm.

[0017] This design ensures that the first flexible component of the floor brush device can contact the surface to be cleaned when the brush moves across it.

[0018] As an optional implementation, the difference between the height dimension of the first flexible member along the radial direction of the brush body and the height dimension of the second flexible member along the radial direction of the brush body is 0.1-1.5 mm.

[0019] This design ensures that both the first and second flexible components have a cleaning effect, while also keeping the hair fluffy at the edge of the second flexible component when it gets tangled in the roller brush assembly, making it easier for the hair to detach from the roller brush assembly.

[0020] As an alternative implementation, the brush body has ventilation holes located between the rotation axis of the flexible member and the brush body; the ventilation holes are radially through the brush body.

[0021] This design increases ventilation efficiency through the vents and prevents hair from getting tangled in the roller brush assembly.

[0022] As an alternative implementation, the flexible element extends from one end of the roller brush body along its length to the other end of the roller brush body along its length; the flexible element includes two extension segments with an included angle between the two extension segments.

[0023] With this design, when the flexible parts scrape the surface to be cleaned, debris can gather at the angle between the two extension sections, improving the efficiency of debris suction.

[0024] As an alternative implementation, the roller brush body includes a roller and a plurality of support portions, the support portions being connected to the side of the roller and protruding from the surface of the roller; the end of the support portion opposite to the central axis of the roller has a slot.

[0025] Multiple flexible components are inserted into multiple slots and protrude from the slots radially along the roller; the height of the protrusion from the slots of different flexible components is different.

[0026] This design allows for easy installation or removal of flexible components via slots.

[0027] Secondly, this application provides a cleaning device, including the aforementioned floor brush device.

[0028] This application provides a floor brush device and cleaning equipment. The floor brush device includes a housing and a roller brush assembly. The housing has a roller brush cavity, and the roller brush assembly is rotatably disposed in the roller brush cavity. The roller brush assembly includes a roller brush body and a plurality of flexible members. The plurality of flexible members are connected to the roller brush body and are spaced apart on the periphery of the roller brush body. At least two of the plurality of flexible members have different height dimensions along the radial direction of the roller brush body. This makes the outline edge of the roller brush assembly non-circular during rotation, so that the hair carried by the flexible members is less likely to become tangled on the roller brush assembly. The hair is in a fluffy state and is more easily sucked into the interior of the floor brush device.

[0029] In addition to the technical problems solved by the embodiments of this application, the technical features constituting the technical solutions, and the beneficial effects brought about by the technical features of these technical solutions described above, other technical problems that can be solved by the floor brush device and cleaning equipment provided by this application, other technical features included in the technical solutions, and the beneficial effects brought about by these technical features will be further explained in detail in the specific embodiments.

[0047] Cleaning equipment such as mite removers, vacuum cleaners, floor scrubbers, and robotic vacuum cleaners are widely used for cleaning home environments.

[0048] In related technologies, cleaning equipment typically includes a roller brush with multiple scraping strips arranged circumferentially. During the cleaning process, a motor drives the roller brush to rotate, causing it to roll along the surface being cleaned. This results in the scraping strips continuously scraping or slapping the surface, thereby lifting dust, hair fibers, and other debris adhering to it. The cleaning equipment also features an air intake, positioned opposite the roller brush. The negative pressure airflow created by the air intake draws the dust and hair into the cleaning equipment.

[0049] However, during the cleaning process of current cleaning equipment, the hair tends to get tangled more and more tightly when the roller brush rotates, affecting the normal rotation of the roller brush.

[0050] To address the aforementioned technical problems, this application provides a floor brush device and cleaning equipment. The floor brush device includes a roller brush assembly, which comprises a roller brush body and a plurality of flexible members spaced apart around the roller brush body. When the roller brush body rotates, it drives the plurality of flexible members to continuously pat the ground to clean the surface to be cleaned. At least two of the flexible members have different height dimensions along the radial direction of the roller brush body, making the outline edges of the plurality of flexible members non-circular. In this way, the hair carried by the flexible members is less likely to become tangled on the roller brush assembly, and the hair is in a fluffy state and is more easily sucked into the interior of the floor brush device.

[0051] The following section provides examples illustrating the application scenarios of the floor brush device and cleaning equipment provided in the embodiments of this application.

[0052] The floor brush device provided in this application embodiment is applied to cleaning equipment. The product types of cleaning equipment may include, but are not limited to, mite removers, vacuum cleaners, mopping machines, floor scrubbers, and robot vacuum cleaners, depending on the product type.

This application embodiment does not specifically limit the types of materials used.

[0054] See Figures 1 to 6 As shown, this application provides a floor brush device 10, which can move and clean the surface to be cleaned.

[0055] The floor brush device 10 includes a housing 200 and a roller brush assembly 100. The housing 200 includes an upper housing 210 and a lower housing 220, which are connected to form a roller brush cavity 230. The roller brush assembly 100 is rotatably disposed in the roller brush cavity 230. The floor brush device 10 also has an air intake 101 disposed within the roller brush cavity 230. The roller brush assembly 100 includes a roller brush body 110 and multiple flexible members 120. The multiple flexible members 120 are connected to the roller brush body 110 and are spaced apart around the roller brush body 110. During cleaning, a motor drives the roller brush body 110 to rotate, causing the multiple flexible members 120 to continuously scrape and pat the surface to be cleaned, rolling up dust, hair, and other debris. This debris is then sucked into the air intake 101 and sent to a debris collection device. At least two of the flexible members 120 have different height dimensions along the radial direction of the roller brush body 110.

[0056] Understandably, if the height dimensions of multiple flexible components 120 along the radial direction of the roller brush body 110 are all the same, then when the roller brush assembly 100 rotates, the paths traced by the edges of the multiple flexible components 120 are circular. When hair fibers are lifted, they easily adhere to the circular contour edge and wrap around the roller brush assembly 100, becoming increasingly tightly wrapped as the roller brush assembly 100 rotates, making it difficult for them to fall off or be sucked into the air intake 101. When at least two flexible components 120 have different height dimensions along the radial direction of the roller brush body 110, the paths traced by the edges of the multiple flexible components 120 are non-circular. When hair fibers are lifted and wrapped around the contour edge of the flexible component 120, they do not easily adhere tightly to the contour edge of the flexible component 120, but remain in a looser state, thus easily detaching from the roller brush assembly 100 and being sucked into the air intake 101.

[0057] As one possible implementation, in the circumferential direction of the roller brush body 110, the height dimensions of two adjacent flexible parts 120 along the radial direction of the roller brush body 110 are different. In this way, when the roller brush assembly 100 rotates, the edge of the cross-sectional profile undulates up and down continuously. While ensuring the cleaning effect of the roller brush assembly 100, the hair is more fluffy when it gets tangled, and it is easier to be sucked into the air intake 101.

[0058] As one possible implementation, the multiple flexible elements 120 include a first flexible element 121 and a second flexible element 122; the height dimension of the first flexible element 121 along the radial direction of the roller brush body 110 is greater than the height dimension of the second flexible element 122 along the radial direction of the roller brush body 110.

[0059] Understandably, due to the height difference between the first flexible member 121 and the second flexible member 122, when the hair fibers are wrapped around the roller brush assembly 100 in the circumferential direction, the outline edge of the first flexible member 121 is in contact with the edge of the first flexible member 121, and the hair fibers are suspended near the outline edge of the second flexible member 122. In this way, the hair fibers are not in a taut state, and thus it is easier for them to detach from the roller brush assembly 100.

[0060] It should be noted that the second flexible element 122 can be a rubber strip. When the floor brush device 10 cleans the surface to be cleaned and the roller brush assembly 100 rotates, in order to ensure the scraping effect of the rubber strip, at least the first flexible element 121 must be in contact with the surface to be cleaned and undergo elastic deformation.

[0061] In some embodiments, when the cleaning device cleans, only the first flexible member 121 contacts the surface to be cleaned, while the second flexible member 122 maintains a distance from the surface to be cleaned. In other embodiments, when the cleaning device cleans, both the first flexible member 121 and the second flexible member 122 can contact the surface to be cleaned. Since the first flexible member 121 has a larger radial height dimension, the first flexible member 121 has a greater degree of elastic deformation than the second flexible member 122 when it contacts the surface to be cleaned.

[0062] As one possible implementation, there are multiple first flexible elements 121 and multiple second flexible elements 122; the multiple first flexible elements 121 and the multiple second flexible elements 122 are alternately spaced in the circumferential direction of the brush body 110.

[0063] For example, there are two first flexible members 121 and two second flexible members 122. The two first flexible members 121 and the two second flexible members 122 are arranged alternately. The first flexible members 121 ensure the scraping and patting effect of the roller brush assembly, and the second flexible members 122 ensure that the hair fibers are in a fluffy state around them when they are wrapped.

[0064] As one possible implementation, the floor brush device 10 also includes a roller 300, which is rotatably connected to the housing 200; when the first flexible member 121 is directly below the axis of the roller brush body 110, the lower edge of the first flexible member 121 in its natural state is lower than the horizontal tangent of the lower edge of the roller 300, and the vertical distance between the lower edge of the first flexible member 121 in its natural state and the horizontal tangent of the lower edge of the roller 300 is greater than 0 mm and less than or equal to 1 mm.

[0065] It is understandable that when the first flexible member 121 is directly below the axis of the brush body 110, its radial edge is at its lowest point in its natural state, that is, its radial edge is at its lowest point when no deformation occurs. Figure 1As shown, the vertical distance between the lower edge of the first flexible member 121 in its natural state and the horizontal tangent of the lower edge of the roller 300 is A, where A is greater than 0 mm and less than or equal to 1 mm. At this height, the first flexible member 121 can ensure good scraping and patting effects, while the elastic deformation will not be too large, resulting in excessive friction.

[0066] It should be noted that the lower edge of the second flexible member 122 in its natural state can be lower than or higher than the horizontal tangent of the lower edge of the roller 300. When the lower edge of the second flexible member 122 in its natural state is lower than the horizontal tangent of the lower edge of the roller 300, both the first flexible member 121 and the second flexible member 122 can contact the surface to be cleaned. When in contact with the surface to be cleaned, the deformation degree of the first flexible member 121 is greater than that of the second flexible member 122. When the lower edge of the second flexible member 122 in its natural state is higher than the horizontal tangent of the lower edge of the roller 300, on a hard surface to be cleaned, only the first flexible member 121 contacts the surface to be cleaned. On a soft surface to be cleaned, since the surface to be cleaned can deform under the pressure of the cleaning equipment, the height dimension of the second flexible member 122 along the radial direction of the roller brush body 110 can contact the surface to be cleaned within a certain range.

[0067] As one possible implementation, the difference between the height dimension of the first flexible member 121 along the radial direction of the roller brush body 110 and the height dimension of the second flexible member 122 along the radial direction of the roller brush body 110 is 0.1-1.5mm. Within this range, it can be ensured that the flexible member 120 can roll up the dust, hair, water stains and other debris on the surface to be cleaned. At the same time, the first flexible member 121 and the second flexible member 122 have a height difference in the radial direction of the roller brush body 110. Since the first flexible member 121 and the second flexible member 122 are alternately arranged, when the hair fibers are wrapped, they are in a hanging state at the edge of the second flexible member 122, rather than a straight state, which makes it easier for the hair fibers to detach from the roller brush assembly 100.

[0068] As one possible implementation, the brush body 110 has a ventilation hole 113 located between the flexible member 120 and the rotation axis of the brush body 110; the ventilation hole 113 is radially through the brush body 110.

[0069] Understandably, along the cleaning direction of the cleaning equipment, the suction port 101 is located on the rear side of the roller brush assembly. When the flexible part 120 contacts the surface to be cleaned, the airflow of the traditional cleaning equipment generally flows into the roller brush cavity 230 from both sides of the roller brush assembly 100 and then into the suction port 101. By setting ventilation holes 113 in the roller brush body 110, the ventilation holes 113 can be connected to the front space of the roller brush assembly 100. Some hair fibers can pass directly through the ventilation holes 113 and be sucked in by the suction port 101, reducing the probability of hair fibers getting tangled in the roller brush assembly 100. At the same time, the ventilation holes 113 increase the ventilation area and improve ventilation efficiency.

[0070] Reference Figure 1 and Figure 4 Define the length direction of the roller brush body 110 as the X direction, the cleaning direction of the cleaning device as the Y direction, and the X direction as perpendicular to the Y direction.

[0071] Reference Figures 1 to 4 In some embodiments, the flexible element 120 extends from one end of the brush body 110 along its length to the other end of the brush body 110 along its length; the flexible element 120 includes two extension segments with an included angle between the two extension segments.

[0072] Understandably, the connection point of the two extension sections can be located in the middle of the length of the roller brush body 110, opposite to the air intake 101. The two extension sections have an included angle, making the flexible component 120 V-shaped. The connection point of the two extension sections protrudes forward in the cleaning direction of the cleaning device. In this way, when the roller brush assembly 100 rotates, the flexible component 120 scrapes the surface to be cleaned, and debris and water stains easily collect in the middle of the flexible component 120, i.e., the connection point of the two extension sections, making it easier for debris and water stains to be sucked into the air intake 101, thereby improving cleaning efficiency. The included angle between the two extension sections of the flexible component 120 is greater than 90° and less than 180°.

[0073] For example, the included angle between the two extensions of the flexible member 120 can be 91°, 95°, 100°, 110°, 130°, 160°, 179°, etc., and the embodiments of this application do not make specific limitations.

[0074] Reference Figures 5 to 6 In other embodiments, the flexible member 120 extends from one end of the brush body 110 along its length to the other end of the brush body 110 along its length, and the flexible member 120 is parallel to the axial direction of the brush body 110.

[0075] Reference Figure 4As one possible implementation, the roller brush body 110 includes a roller 111 and a plurality of support portions 112. The support portions 112 are connected to the side of the roller 111 and protrude from the surface of the roller 111. One end of the support portion 112 away from the central axis of the roller 111 has a slot 1121. A plurality of flexible members 120 are respectively inserted into the plurality of slots 1121 and protrude from the slots 1121 radially along the roller 111. The height of the different flexible members 120 protruding from the slots 1121 is different.

[0076] It should be noted that the flexible component 120 may have a plug-in portion 123, which can be inserted into the slot 1121 to connect the flexible component 120 to the roller brush body 110. During disassembly, the plug-in portion 123 can be simply pulled out of the slot 1121 for repair or replacement of the flexible component 120. The slots 1121 of the multiple support portions 112 may be of the same size, and the plug-in portions 123 of different flexible components 120 are adapted to different slots 1121 to facilitate the installation and disassembly of the flexible components 120. The multiple support portions 112 have the same radial height along the roller brush body 110. The first flexible component 121 and the second flexible component 122 have different dimensions, resulting in different protrusions from the slot 1121 after installation.

[0077] In some embodiments, both the flexible member 120 and the support portion 112 have two extensions. The included angle between the two extensions of the support portion 112 matches the included angle between the two extensions of the flexible member 120. The two extensions of the flexible member 120 can be inserted into or removed from both ends of the slot 1121 to achieve installation and disassembly.

[0078] For example, the included angle between the two extensions of the support portion 112 can be 91°, 95°, 100°, 110°, 130°, 160°, 179°, etc., and the embodiments of this application do not make specific limitations.

[0079] In other embodiments, both the flexible element 120 and the support portion 112 are parallel to the axial direction of the brush body 110. The flexible element 120 can be inserted into or removed from one end of the slot 1121 as a whole, thereby enabling installation and disassembly.

[0080] As one possible implementation, at least one end of the roller brush body 110 can be provided with a support base 130. The support base 130 can be connected to the roller brush body 110 by means of snap-fit, thread, etc. The side of the support base 130 connected to the roller brush body 110 is provided with multiple card interfaces. When the support base 130 is connected to the roller brush body 110, the slot 1121 and the insertion part 123 of the flexible member 120 fall into the card interface. The support base 130 can support the support part 112 and the flexible member 120, improve the structural stability, and at the same time prevent the flexible member 120 from falling out of the slot 1121.

[0081] It should be noted that the ventilation holes 113 can be disposed on the support portion 112 and located between the slot 1121 and the roller 111. There can be multiple ventilation holes 113, which are arranged along the length direction of the roller brush body 110. The shape of the ventilation holes 113 can be circular, square, etc., and this embodiment does not impose a specific limitation. The ratio of the area of ​​the ventilation hole 113 to the area of ​​the roller brush assembly 100 is 1%-99%.

[0082] For example, the ratio of the area of ​​the ventilation hole 113 to the cross-sectional area of ​​the roller brush assembly 100 is 1%, 5%, 10%, 20%, 50%, 90%, 99%, etc., and this application embodiment does not make specific limitations.

[0083] This application also provides a cleaning device, including the aforementioned floor brush device 10 and a device body, with the floor brush device 10 connected to the device body. The device body is equipped with a motor, a fan, and a dust cup. The motor drives the fan and the roller brush assembly 100. The floor brush device 10 has a suction channel 102, one end of which is a suction port 101, and the other end is connected to the fan. When the fan is started, it provides negative pressure suction to the suction port 101, and debris is sucked in and enters along the suction channel 102 and is collected in the dust cup.

[0084] This application provides a floor brush device 10 and a cleaning device. The floor brush device 10 includes a housing 200 and a roller brush assembly 100. The housing 200 has a roller brush cavity 230, and the roller brush assembly 100 is rotatably disposed in the roller brush cavity 230. The roller brush assembly 100 includes a roller brush body 110 and a plurality of flexible members 120. The plurality of flexible members 120 are connected to the roller brush body 110 and are spaced apart on the periphery of the roller brush body 110.
