Description

Technical Field

[0001] This utility model belongs to the field of household appliance technology, and specifically relates to a roller brush and a vacuum cleaner. Background Technology

[0002] Robotic vacuum cleaners are becoming increasingly popular, greatly simplifying household cleaning and reducing the burden of housework. However, because the brush of a robotic vacuum cleaner rotates during dust removal, it often gets tangled with hair or fine filaments. If it's a bristle brush, cleaning it can be difficult and requires the use of tools.

[0003] To address the aforementioned issues, a roller brush with rubber brush strips has been proposed. During cleaning, dirt is propelled forward by the rubber brush strips and drawn into the vacuum cleaner's air duct for suction. However, because the rubber brush strips deform during cleaning, the pure rubber brush exhibits significant bending deformation and high stress, resulting in a shorter service life.

[0004] Therefore, in view of the above shortcomings, this utility model is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a roller brush and a vacuum cleaner to solve the problem of low service life of roller brushes in the prior art.

[0006] The first aspect of this utility model provides a roller brush, including a roller brush shaft and a roller brush body sleeved on the outside of the roller brush shaft, wherein the roller brush shaft is used to support and drive the roller brush body to rotate.

[0007] The roller brush body includes a body and brush strips disposed on the outer periphery of the body. The brush strips extend along the axial direction of the roller brush body, wherein at least one brush strip has a first support portion and a second support portion connected to the body, and a gap is formed between the first support portion and the second support portion.

[0008] The roller brush provided by this utility model may also have the following additional technical features:

[0009] In one specific embodiment of the present invention, the first support portion includes a first end connected to the body and a second end away from the body; the second support portion includes a third end connected to the body and a fourth end away from the body; the second end is connected between the third end and the fourth end.

[0010] In one specific embodiment of this utility model, the first support portion includes a first end connected to the main body and a second end away from the main body; the second support portion includes a third end connected to the main body and a fourth end away from the main body; wherein,

[0011] The thickness of the first support portion is gradually reduced in a stepped manner from the first end to the second end; and / or

[0012] The thickness of the second support portion is set in a gradually thinning step from the third end to the fourth end.

[0013] In one specific embodiment of this utility model, the distance from the first end to the second end of the first support portion is 2-4 mm, and the distance from the third end to the fourth end of the second support portion is 9-13 mm; and / or

[0014] The thickness of the first support portion and the second support portion is 0.6-0.8 mm.

[0015] In one specific embodiment of this utility model, the main body is cylindrical, and the first ends of the first support portion and the second support portion are connected to the outer wall surface of the main body; or

[0016] The body includes a plurality of strips spaced circumferentially along the roller brush axis, and the first ends of the first support portion and the second support portion of the same brush strip are respectively connected to two adjacent strips.

[0017] In one specific embodiment of this utility model, the brush strips are arranged in a V-shape on the body along the length direction of the body.

[0018] In one specific embodiment of this utility model, the vertices of multiple brush strips are located on the same circumference, and the orientation of the vertices is the same as the rotation direction of the roller brush.

[0019] In one specific embodiment of this utility model, a first positioning part is provided on the roller brush shaft, and a second positioning part is provided on the inner wall of the body. The first positioning part and the second positioning part are adapted to be circumferentially positioned.

[0020] In one specific embodiment of this utility model, the roller brush body is an integrally formed structure.

[0021] The second aspect of this utility model also provides a vacuum cleaner, comprising:

[0022] Roller brush connector; and

[0023] A roller brush as described in any of the above.

[0024] The roller brush provided by this utility model includes a roller brush shaft and a roller brush body sleeved on the roller brush shaft. The roller brush strip includes a body and brush strips disposed on its outer periphery. Thus, when the vacuum cleaner is working, the driving force acts on the roller brush shaft, and the roller brush shaft rotates, thereby causing the roller brush body and the brush strips on it to rotate relative to the object being cleaned. Larger dust and dirt particles are carried by the brush strips on the roller brush body to the gap between two adjacent rows of brush strips and are pushed towards the air inlet of the vacuum cleaner's air inlet duct as it rotates. Under the action of the vacuum cleaner's suction, they are sucked into the vacuum cleaner, realizing the normal operation of the vacuum cleaner. At the same time, since at least one brush strip includes a first support part and a second support part, and a gap is formed between the first support part and the second support part, when the brush strip rotates and comes into contact with the object being cleaned, the first support part and the second support part can not only support each other, but the gap between the first support part and the second support part can also form an airbag, thereby providing support for the first support part and the second support part. Therefore, the deformation of the brush strip is relatively small, and the breakage is also relatively small, thereby improving the service life of the brush strip and even the roller brush.

[0038] One aspect of this utility model embodiment provides a roller brush 100, please refer to... Figures 1-4 The roller brush 100 includes a roller brush shaft 100 and a roller brush body 20 sleeved on the outside of the roller brush shaft 100. The roller brush shaft 100 is used to support and drive the roller brush body 20 to rotate. The roller brush body 20 includes a body 21 and brush strips 22 disposed on the outer periphery of the body 21. The brush strips 22 extend along the axial direction of the roller brush body 20. At least one brush strip 22 has a first support portion 23 and a second support portion 24 connected to the body 21, and a gap is formed between the first support portion 23 and the second support portion 24.

[0039] Specifically, the roller brush shaft 10 is cylindrical and can be made of rigid plastic or metal, serving as a rotatable connection to the vacuum cleaner's mounting structure. The roller brush body 20 is made of an inherently elastic material, such as natural rubber, synthetic rubber, or TPE (Thermoplastic Elastomer). The roller brush body 20 is fitted onto the roller brush shaft 10 and rotates with it under its support and drive. By configuring the roller brush shaft 10 and roller brush body 20, the connection to the vacuum cleaner's mounting structure is ensured, while noise during use is reduced, thus meeting noise reduction requirements.

[0040] The roller brush body 20 includes a main body 21 and brush strips 22 disposed on the outer periphery of the main body 21 and extending along the axial direction of the roller brush body 20. Multiple brush strips 22 are evenly distributed circumferentially along the roller brush body 20. Due to the gap 'a' formed between adjacent brush strips 22, during cleaning, larger dust and dirt particles are carried by the brush strips 22 on the roller brush body 20 to the gap 'a' between adjacent rows of brush strips 22. As the roller brush body 20 rolls, the brush strips 22 carry these larger dust and dirt particles towards the air inlet of the vacuum cleaner's air intake duct. Under the suction of the vacuum cleaner, these larger dust and dirt particles are sucked into the vacuum cleaner.

[0041] The number of brush strips (22) is unlimited; for example, 4, 6, or 8. Please refer to [link / reference]. Figure 3 and Figure 4 In this embodiment, there are 5 brush strips 22, which takes into account both the cleaning and sweeping effect and the installation of the brush strips 22.

[0042] At least one brush strip 22 has a first support portion 23 and a second support portion 24 connected to the body 21. Both the first support portion 23 and the second support portion 24 extend along the length direction of the brush strip 22, and a gap a is formed between the first support portion 23 and the second support portion 24. Thus, when the roller brush 100 is cleaning, not only can the object being cleaned be cleaned by the brush strip 22, but when the brush strip 22 is subjected to force due to contact with the object being cleaned, the first support portion 23 and the second support portion 24 can not only support each other, but the gap a between the first support portion 23 and the second support portion 24 can also form an airbag, thereby providing support for the first support portion 23 and the second support portion 24. Therefore, the deformation of the brush strip 22 is relatively small, the stress is relatively small, and the damage caused by deformation is relatively reduced, thereby improving its service life.

[0043] It should be noted that the brush strip 22 can be a single piece or a multi-segment arrangement with intervals. Correspondingly, the first support portion 23 and the second support portion 24 can be a single piece or a multi-segment arrangement with intervals. When the brush strip 22 is a single piece, the first support portion 23 and / or the second support portion 24 are also a single piece. In this embodiment, both the first support portion 23 and the second support portion 24 are single pieces.

[0044] It should be noted that only one brush strip 22 may be provided with the first support portion 23 and the second support portion 24, while the other brush strips 22 may be formed in a sheet shape. Preferably, in this embodiment, all of the multiple brush strips 22 are provided with the first support portion 23 and the second support portion 24.

[0045] The roller brush 100 provided in this embodiment of the utility model includes a roller brush shaft 10 and a roller brush body 20 sleeved on the roller brush shaft 10. Each roller brush 100 includes a body 21 and brush strips 22 disposed on its outer periphery. Thus, when the vacuum cleaner is working, the driving force acts on the roller brush shaft 10, causing the roller brush shaft 10 to rotate, which in turn drives the roller brush body 20 and its brush strips 22 to rotate relative to the object being cleaned. Larger dust particles are carried by the brush strips 22 on the roller brush body 20 to the gap a between adjacent rows of brush strips 22, and are pushed towards the air inlet of the vacuum cleaner's air inlet duct as it rotates. Under the suction force of the vacuum cleaner, they are sucked into the vacuum cleaner, thus achieving vacuum cleaning. The brush bar 22 is designed for normal operation. Since at least one brush bar 22 includes a first support portion 23 and a second support portion 24, and a gap a is formed between the first support portion 23 and the second support portion 24, when the brush bar 22 rotates and contacts the object being cleaned, the first support portion 23 and the second support portion 24 can not only support each other, but the gap a between the first support portion 23 and the second support portion 24 can also form an airbag, thereby providing support for the first support portion 23 and the second support portion 24. Therefore, the deformation of the brush bar 22 is relatively small, and the breakage is relatively small, thereby improving the service life of the brush bar 22 and even the roller brush 100.

[0046] In one embodiment, the first support portion 23 includes a first end connected to the body 21 and a second end away from the body 21; the second support portion 24 includes a third end connected to the body 21 and a fourth end away from the body 21; the second end is connected between the third end and the fourth end.

[0047] The area between the third and fourth ends forms the central region of the second support portion 24. The second end of the first support portion 23 is connected between the third and fourth ends, i.e., the second end is connected to the central region of the second support portion. By connecting the second end of the first support portion 23 to the central region of the second support portion 24, the first support portion 23 has greater strength because the distance from its first end to its second end is smaller than the distance from its third end to its fourth end of the second support portion 24, thus improving its support capacity. The distance from the third end to its fourth end of the second support portion 24 is larger, so the portion extending beyond the first support portion 23 has better deformation capacity, thereby improving cleaning efficiency. Simultaneously, because the second end of the first support portion 23 is connected to the central region of the second support portion 24, dust and dirt particles will not enter the gap a between the first support portion 23 and the second support portion 24, thus facilitating the cleaning of the roller brush body 20.

[0048] It should be noted that the second end of the first support part 23 can also abut against the middle of the second support part 24, that is, the second end of the first support part 23 is not connected to the second support part 24, and the two are only abutted against each other by structural design.

[0049] In one embodiment, along the rotation direction of the roller brush 100, the first support portion 23 is disposed in front of the second support portion 24. In this way, the first support portion 23, which has higher strength, comes into contact with the object being cleaned first, thereby ensuring that the second support portion 24 is supported throughout the entire cleaning process. This reduces the deformation of the second support portion 24, minimizes damage, and further extends the service life of the roller brush 100.

[0050] In one embodiment, the thickness of the first support portion 23 is provided in a gradually thinning stepped manner from the first end to the second end; and / or the thickness of the second support portion 24 is provided in a gradually thinning stepped manner from the third end to the fourth end.

[0051] Specifically, the thinner step refers to the formation of multiple segments of varying thickness on the first support portion and / or the second support portion along a predetermined direction, with the thickness of the multiple segments decreasing sequentially along the predetermined direction. Specifically, in this embodiment, the first support portion has multiple segments of decreasing thickness from the first end to the second end, and / or the second support portion has multiple segments of decreasing thickness from the third end to the fourth end.

[0052] In this embodiment, by setting the thickness of the first support portion 23 and / or the second support portion 24 in a stepped manner, the strength of the first end of the first support portion 23 is strengthened while the strength of its second end is reduced, and the strength of the third end of the second support portion 24 is strengthened while the strength of its fourth end is reduced. Thus, when used for cleaning, the first and third ends have poor deformation capabilities, which reduces the relative force between them and the body 21, thereby reducing tearing between the first and second support portions 23 and the second support portion 24 and the body 21. The second and fourth ends have strong deformation capabilities, which further ensures the cleaning ability of the brush strip 22, and thus ensures the cleaning performance of the roller brush 100.

[0053] Optionally, the thickness of the first support portion 23 is set in 2-5 steps from the first end to the second end, and the thickness of the second support portion 24 is set in 2-5 steps from the third end to the fourth end, for example, in three or four steps, depending on the height of the first support portion 23 and the second support portion 24. In this embodiment, the thickness of both the first support portion 23 and the second support portion 24 is set in two steps.

[0054] In one embodiment, the thickness of the first support portion 23 and the second support portion 24 is 0.6-0.8 mm. The thickness of the first support portion 23 and the second support portion 24 can be the same or different. For example, the thickness of the first end of the first support portion 23 and the third end of the second support portion 24 can be 0.8 mm, and the thickness of the second end and the fourth end can be 0.6 mm, or the thickness of the first end and the third end can be 0.75 mm, and the thickness of the second end and the fourth end can be 0.7 mm, or the thickness of the first end of the first support portion 23 can be 0.8 mm, the thickness of the second end can be 0.6 mm, the thickness of the third end of the second support portion 24 can be 0.75 mm, and the thickness of the fourth end can be 0.7 mm, etc.

[0055] In one embodiment, the distance between the first end and the second end of the first support portion 23 is 2-4 mm, and the distance between the third end and the fourth end of the second support portion 24 is 9-13 mm. Specifically, the distance between the first end and the second end of the first support portion 23 can be 3 mm, and the distance between the third end and the fourth end of the second support portion 24 can be 10 mm, 11 mm, or 12 mm.

[0056] In one embodiment, the body 21 is cylindrical, with the first end of the first support portion 23 and the third end of the second support portion 24 connected to the outer wall surface of the body 21. Because the body 21 is cylindrical, the cylindrical structure of the first support portion 23, the second support portion 24, and the body 21 encloses three adjacent sides of the airbag. This structure further strengthens the roller brush body 20, thereby improving the supporting effect of the airbag and increasing the service life of the first support portion 23 and the second support portion 24.

[0057] In one embodiment, the body 21 includes a plurality of strips spaced circumferentially along the roller brush shaft 10, and the first end of the first support portion 23 and the third end of the second support portion 24 of the same brush strip 22 are respectively connected to two adjacent strips.

[0058] Specifically, the multiple strips of the body 21 are connected by the first support 23 and the second support 24 to form a cylindrical structure. At this time, the first support 23, the second support 24 and the outer surface of the roller brush shaft 10 located between adjacent strips enclose the three adjacent sides of the airbag a.

[0059] The above structure can reduce the material cost of the roller brush body 20, thereby reducing the cost of the roller brush 100.

[0060] In one embodiment, the brush strips 22 are arranged in a V-shape along the length of the body 21. Thus, as the vacuum cleaner moves forward, dust from both sides is collected by the V-shaped brush strips 22 and drawn into the center, where it is then sucked into the vacuum cleaner, improving dust removal efficiency.

[0061] As an alternative implementation, the brush strips 22 can also be arranged in a spiral pattern on the outer periphery of the body 21, so that the roller brush body 20 pushes the dust to one side through the brush strips 22 of the bolt.

[0062] In one embodiment, the apexes of the plurality of brush strips 22 are located on the same circumference. Preferably, the apexes face the same direction as the rotation direction of the roller brush 100. This allows dust to be more effectively pushed towards the air inlet and into the dustbin or dust bag inside the vacuum cleaner.

[0063] In one embodiment, the brush roller 10 is provided with a first positioning part 11, and the inner wall of the body 21 is provided with a second positioning part 25. The first positioning part 11 and the second positioning part 25 are adapted to be circumferentially positioned.

[0064] By fitting the main body 21 onto the roller brush shaft 10 and adapting it to the first positioning part 11 via the second positioning part 25, circumferential positioning of the roller brush body 20 and the roller brush shaft 10 is achieved, so that the rotation of the roller brush shaft 10 can drive the roller brush body 20 to rotate together, thereby driving the first support part 23 and the second support part 24 to rotate to achieve cleaning.

[0065] In one embodiment, one of the first positioning part 11 and the second positioning part 25 is a slot, and the other is a connector. Both the slot and the connector are arranged along the axial direction of the brush body 20. By providing the slot and connector along the axial direction of the brush body 20, when the brush shaft 10 is inserted into the through hole of the brush body 20 along its axial direction, the slot and the connector can also be synchronously fitted and inserted, thereby achieving circumferential positioning of the brush shaft 10 and the brush body 20.

[0066] Optionally, the first positioning part 11 is a connector and the second positioning part 25 is a slot. In this embodiment, the first positioning part 11 is a slot and the second positioning part 25 is a connector. In this way, the assembled slot and connector are located inside the roller brush shaft 10 and do not occupy the space of the body 21, thereby reducing the thickness of the body 21 and thus reducing the cost of the roller brush 100.

[0067] In one embodiment, the slot and the connector have a T-shaped cross-section, which can improve the fit strength between the slot and the connector, prevent the connector from sliding out of the slot, and thus improve the connection strength between the roller brush shaft 10 and the roller brush body 20.

[0068] The slot includes a first slot arranged circumferentially along the roller brush shaft 10 and a second slot arranged radially along the roller brush shaft 10, with the first and second slots forming a T-shape. In this embodiment, the end of the second slot is located on the outer circumferential surface of the roller brush shaft 10, and the first slot is located within the shaft body of the roller brush shaft 10. Thus, when the slot mates with the connector, the first slot can restrain part of the connector located therein, thereby preventing the connector from sliding out of the slot and improving the connection strength between the roller brush shaft 10 and the roller brush body 20.

[0069] Optionally, there are other ways to set the slot. For example, the first slot can also be set on the outer peripheral surface of the brush shaft 1010. You can choose the specific one according to your needs.

[0070] The number of card slots is unlimited, specifically ranging from 2 to 10, for example, 4, 6, or 8. (See also...) Figure 1 and Figure 2 In this embodiment, there are 3 slots, which not only ensures the connection strength between the roller brush shaft 10 and the roller brush body 20, but also facilitates the positioning of the slots and connectors when assembling the roller brush shaft 10 and the roller brush body 20.

[0071] In one embodiment, the roller brush body 20 is a one-piece molded structure. This simplifies the manufacturing process and improves processing efficiency.

[0072] The second aspect of this utility model also provides a vacuum cleaner, including a roller brush 100 connector and a roller brush 100 as described in any of the above embodiments. Specifically, the specific structure of the roller brush 100 is as described in the above embodiments, and will not be repeated here. Since the vacuum cleaner of this embodiment has all the technical features of the roller brush 100 described above, it also has at least all the beneficial effects of the roller brush 100 described above.

[0073] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model 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 utility model.
