[0022] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the scope of protection of the present application.

[0023] The present application first proposes a side brush, as Figures 1 to 11 shown. The side brush includes a main body portion 10 and at least two cleaning branch portions 102. The at least two cleaning branch portions 102 are directly or indirectly connected to the main body portion 10 at intervals; wherein, when the main body portion 10 rotates, a rotation plane c is formed. The included angle A1 formed by the connection line between the projection points of the two cleaning branch portions 102 with the farthest distance in the rotation plane c and the rotation center of the rotation plane c is less than 120°.

[0024] In an application scenario, the side brush can be used for a cleaning device. The main body portion 10 rotates around a rotation axis b in the rotation plane c to drive the cleaning branch portions 102 to rotate. The cleaning device can control the rotation of the side brush in the rotation plane c of the main body portion 10, which is convenient for realizing the cleaning operation on the surface to be cleaned, such as sweeping dust, debris and other garbage.

[0025] It should be noted that the projection point refers to the projection point of the central axis of the cleaning branch 102 in the rotation plane c.

[0026] It should be noted that in this application, without special instructions, the specific structure of the cleaning branch 102 is not limited. For example, in an application scenario (not shown in the figure), the cleaning branch includes a cleaning member 12, and the cleaning member 12 is directly connected to the main body 10. The included angle formed by the connection line between the projection points of the two cleaning members 12 with the farthest distance on the rotation plane c and the rotation center of the rotation plane c is less than 120°. The cleaning member 12, such as bristles, can be used to clean the surface to be cleaned. Another example is that in another application scenario, the cleaning branch 102 includes a first connecting portion 11 and a cleaning member 12, and the cleaning member 12 is detachably connected to the main body 10 through the first connecting portion 11. The included angle formed by the connection line between the projection points of the two cleaning members 12 with the farthest distance on the rotation plane c and the rotation center of the rotation plane c is less than 120°. Another example is that in another application scenario (not shown in the figure), the cleaning branch 102 includes a first connecting portion 11, and the included angle formed by the connection line between the projection points of the two first connecting portions 11 with the farthest distance on the rotation plane c and the rotation center of the rotation plane c is less than 120°. Among them, the first connecting portion 11 is used to install the cleaning member 12, and at this time, the side brush serves as a side brush holder and can be used for cleaning equipment after installing the cleaning member 12.

[0027] Among them, there are multiple projection points of the cleaning branch 102 on the rotation plane c. The two cleaning branches 102 with the farthest distance can be called the first cleaning branch and the second cleaning branch. There are multiple first projection points of the first cleaning branch on the rotation plane c, and there are multiple second projection points of the second cleaning branch on the rotation plane c. The connection line between the first projection point and the rotation center is used as the first connection line, and the connection line between the second projection point and the rotation center is used as the second connection line. The included angle formed by any first connection line and any second connection line is less than 120°.

[0028] Multiple cleaning branches 102 are connected to the main body 10 at intervals, which can improve the cleaning effect and cleaning range of the side brush; the included angle A1 formed by the connection line between the projection points of the two cleaning branches 102 with the farthest distance on the rotation plane c and the rotation center of the rotation plane c is less than 120°, which can reduce the risk of the cleaning branch 102 winding around slender objects such as hair and wires when the side brush drives the cleaning branch 102 to rotate. For example, it can reduce the risk of hair entanglement between multiple cleaning branches 102 and affect the cleaning effect. Therefore, this setting can also improve the convenience of cleaning and maintaining the cleaning branch 102. Therefore, this setting can reduce the risk of the side brush winding around slender objects such as hair and wires, improve the cleaning effect and the user experience.

[0029] Furthermore, the arrangement of multiple cleaning branches 102 enables larger particulate contaminants that are knocked away to be retrieved by other cleaning branches 102 when the cleaning branches 102 rotate. Therefore, the risk of larger particulate contaminants being knocked away by the side brush when driving the cleaning branches 102 to rotate can be reduced.

[0030] In some embodiments, the included angle A1 is greater than 0° and less than or equal to 119°.

[0031] For example, the value range of the included angle A1 of the fan-shaped area is from 0° to 10°, from 0° to 25°, from 0° to 33°, from 0° to 36, from 0° to 39°, from 0° to 40°, from 0° to 55°, from 0° to 60°, from 0° to 89°, from 0° to 90°, from 0° to 105°, from 0° to 115°, from 0° to 118°, from 0° to 119°, from 10° to 22°, from 15° to 38°, from 10° to 58°, from 12° to 69°, from 32° to 87°, from 10° to 105°, from 12° to 99°, from 20° to 119°, from 30° to 119°, from 40° to 110°, from 60° to 119°, or from 66° to 108°, etc.

[0032] For example, the included angle A1 of the fan-shaped area is 5°, 18°, 29°, 36°, 45°, 65°, 80°, 89°, 90°, 102.5°, 100°, 60°, 30°, 110°, or 119°, etc.

[0033] In some embodiments, the included angle A1 of the fan-shaped area is equal to 119°.

[0034] This arrangement can not only enable the side brush to achieve a better cleaning effect, but also reduce the risk of multiple cleaning branches being entangled with slender objects such as hair when cleaning the surface to be cleaned, and can better reduce the risk of larger particulate matter being knocked away during the cleaning process, improving the user experience.

[0035] In some embodiments, the projections of multiple cleaning branches 102 in the rotation plane c are evenly distributed in a fan-shaped area with an included angle A1 less than 120°, that is, in Figure 4 the illustrated embodiment, the angle of the included angle A2 is equal to the angle of the included angle A3, so that the projections of multiple cleaning branches 102 in the rotation plane c are evenly distributed in a fan-shaped area with an included angle A1 less than 120°. The even distribution facilitates achieving a more uniform cleaning effect, and the structure is simple and convenient for production.

[0036] In some embodiments, it is also possible to arrange that the projections of multiple cleaning branches 102 in the rotation plane c are not evenly distributed in a fan-shaped area with an included angle A1 less than 120°, that is, in Figure 4In the illustrated embodiment, the angle of the included angle A2 is not equal to the angle of the included angle A3, so that the projections of the plurality of cleaning branches 102 in the rotation plane c are unevenly distributed in the sector area where the included angle A1 is less than 120°, and no specific limitation is made.

[0037] In some embodiments, the plurality of cleaning branches 102 are arranged in sequence along the rotation direction a of the main body 10, and the distances from the ends of the plurality of cleaning branches 102 facing away from the main body 10 to the rotation axis b of the main body 10 decrease in sequence along the rotation direction a.

[0038] As Figure 5 shown, for a certain main body 10, in the rotation direction a of the main body 10 itself, the distances from the second ends of the corresponding cleaning branches 102 to its rotation axis b decrease in sequence along the rotation direction a, that is, M3 > M2 > M1. Therefore, the ability to prevent large particulate contaminants from being blown away can be improved, and the cleaning effect can be improved.

[0039] The rotation direction a of the main body 10 is not limited. In an application scenario, the cleaning device includes two side brushes, which are respectively arranged on the left side and the right side, and the cleaning branches 102 of the side brushes extend toward the side of the main body 10 close to the surface to be cleaned. When looking at the surface to be cleaned, the main body 10 of the left side brush drives the corresponding cleaning branch 102 to rotate clockwise, and the main body 10 of the right side brush drives the corresponding cleaning branch 102 to rotate counterclockwise.

[0040] The beneficial effect of the above setting is that the cleaning branches 102 are arranged in sequence along the rotation direction a of the main body 10, which is convenient for improving the cleaning effect of the cleaning device on the surface to be cleaned when the main body 10 drives the cleaning branches 102 to rotate; the distances from the ends of the plurality of cleaning branches 102 facing away from the main body 10 to the rotation axis b of the main body 10 decrease in sequence along the rotation direction a, which can improve the ability to prevent large particulate contaminants from being blown away and improve the cleaning effect.

[0041] In some embodiments, it is also possible to set the distances from the ends of the plurality of cleaning branches 102 facing away from the main body 10 to the rotation axis b to be equal, that is, in Figure 5 the illustrated embodiment, M3 = M2 = M1 is set.

[0042] In some embodiments, as Figure 4 、 Figure 5 、 Figure 6 shown, the projection of the cleaning branch 102 in the rotation plane c extends along the vertical direction of the rotation axis b of the main body 10.

[0043] This setting has a simple structure and is convenient for production; further, when the cleaning branch 102 includes at least a first connecting portion 11, and the projection of the first connecting portion 11 in the rotation plane c extends along the vertical direction of the rotation axis b of the main body portion 10, this setting is convenient for arranging the cleaning member 12. For example, in an application scenario, an installation hole with an axis parallel to the extending direction of the first connecting portion 11 can be arranged at the connecting end 13 (for connecting the cleaning member 12) of the first connecting portion 11 for installing the cleaning member 12. When the cleaning member 12 includes a linear cleaning member, this setting is convenient for making the projection of the cleaning member 12 in the rotation plane c extend along the vertical direction of the rotation axis b. Therefore, it is convenient to adjust the projection of the cleaning member 12 in the rotation plane c to be located within a sector area where the included angle A1 is less than 120° by adjusting the first connecting portion 11, that is, the included angle formed by the connecting lines between the projection points of the two cleaning members 12 with the farthest distance in the rotation plane c and the rotation center of the rotation plane c is less than 120°. Therefore, the risk of the cleaning member 12 winding around slender objects such as hair and wires can be reduced, and the cleaning effect and the user experience can be improved.

[0044] In some embodiments, the cleaning branch 102 includes a first connecting portion 11 connected to the main body portion 10, and the first connecting portion 11 is used for installing the cleaning member 12.

[0045] Specifically, the cleaning branch 102 includes at least a first connecting portion 11. In some application scenarios, the cleaning branch 102 further includes a cleaning member 12; in other application scenarios (not shown in the figure), the cleaning branch 102 does not include a cleaning member 12, and the cleaning branch 102 includes a first connecting portion 11. At this time, the side brush can be used as a side brush holder for installing the cleaning member 12.

[0046] This setting is convenient for realizing the detachable installation of the cleaning member 12, such as through conventional detachable connection methods such as snap connection. The detachable connection is convenient for the user to repair or replace the cleaning member 12 as needed during the use of the product. For example, a certain or several worn cleaning members 12 can be specifically replaced to improve the cleaning effect of the side brush, which can reduce the user's usage cost and improve the user experience; further, the side brush includes at least two cleaning branches 102, so the side brush includes at least two first connecting portions 11. This setting is convenient for adjusting the distribution mode of the cleaning members 12 by adjusting the distribution mode of the first connecting portions 11 in the sector area to improve the flexibility of the structural design of the side brush.

[0047] In other embodiments, the first connecting portion and the main body portion are detachably arranged, which is convenient for improving the multi-scenario applicability of the side brush.

[0048] In other embodiments, the cleaning member can be fixedly connected to the connecting end, and the specific connection method is not limited.

[0049] In some application scenarios, the cleaning branch 102 includes at least a first connecting portion 11. By setting the first connecting portion 11 with different length dimensions, the distance from the end of the cleaning member 12 away from the main body portion 10 to the rotation axis b of the main body portion 10 can be gradually reduced along the rotation direction a, reducing the production complexity of the side brush.

[0050] In some embodiments, the cleaning branch 102 includes at least a first connecting portion 11. The first connecting portions 11 can be arranged in sequence along the rotation direction a of the main body portion 10. The distance from the end of the first connecting portion 11 away from the main body portion 10 to the rotation axis b of the main body portion 10 is gradually reduced along the rotation direction a. The end of the first connecting portion 11 away from the main body portion 10 serves as a connecting end 13 for installing the cleaning member 12.

[0051] For example, as Figure 5 shown, the side of the first connecting portion 11 away from the main body portion 10 extends in the direction away from the main body portion 10 to form a plurality of ends with different extension lengths. Connecting ends 13 for connecting the cleaning member 12 are respectively arranged at the plurality of ends, that is, L3 > L2 > L1 can be set. Furthermore, the distance from the plurality of connecting ends 13 to the rotation axis b of the main body portion 10 can be gradually reduced along the rotation direction a by adjusting the extension length.

[0052] This setting facilitates the use of a plurality of cleaning members 12 with the same shape and size. Therefore, it is convenient to achieve the mass production of the cleaning members 12, which can reduce the production cost of the cleaning members 12 and improve the assembly convenience.

[0053] In some embodiments, the plurality of first connecting portions 11 are integrally provided to form a second connecting portion 101 connected to the main body portion 10. The second connecting portion 101 is provided with a plurality of connecting ends 13, and the connecting ends 13 are used for installing the cleaning member 12.

[0054] The above setting has a simple structure and is convenient for setting the cleaning member 12.

[0055] In some embodiments, as Figure 7 、 Figure 8 shown, the second connecting portion 101 includes a fan-shaped connecting portion, and a plurality of connecting ends 13 are arranged at intervals on the fan-shaped connecting portion along the rotation direction a of the main body portion 10.

[0056] Specifically, the second connecting portion 101 extends along the circumferential direction of the main body portion 10 to form a fan-shaped connecting portion. On the side of the second connecting portion 101 facing away from the main body portion 10, a plurality of connecting ends 13 are arranged at intervals along the circumferential direction of the main body portion 10. This setting facilitates adjusting the coverage range of the projections of the plurality of connecting ends 13 in the rotation plane c of the main body portion 10 by setting the included angle of the fan-shaped connecting portion. Furthermore, it is convenient to make the projections of the plurality of connecting ends 13 in the rotation plane c located within a fan-shaped area where the included angle A1 is less than 120°. Moreover, it is convenient to make the projection of the cleaning member 12 in the rotation plane c located within the fan-shaped area, that is, the included angle formed by the connecting lines between the projection points of the two cleaning members 12 with the farthest distance in the rotation plane c and the rotation center of the rotation plane c is less than 120°. Therefore, it can facilitate reducing the risk of the cleaning member 12 being wound around slender objects such as hair and wires, and improving the cleaning effect and the user experience.

[0057] In some embodiments, the plurality of connecting ends 13 arranged at intervals along the circumferential direction can be evenly distributed within the fan-shaped area to improve production convenience; of course, in Figure 8 the illustrated embodiment, the plurality of connecting ends 13 arranged at intervals along the circumferential direction can also be unevenly distributed within the fan-shaped area.

[0058] In some embodiments, as Figure 10 shown, the second connecting portion 101 includes a first connecting rod 103. One end of the first connecting rod 103 is connected to the main body portion 10, and the other end forms a plurality of connecting branches 104. The projection of the first connecting rod 103 in the rotation plane c of the main body portion 10 extends along the direction perpendicular to the rotation axis b of the main body portion 10. At least part of the connecting branches 104 form an acute angle with the first connecting rod 103, and the plurality of connecting ends 13 are arranged on the plurality of connecting branches 104.

[0059] The connecting end 13 is used to connect the cleaning member 12; the projection of the first connecting rod 103 in the rotation plane c of the main body portion 10 extends along the direction perpendicular to the rotation axis b of the main body portion 10, and the structure is simple; setting at least part of the connecting branches 104 to form an acute angle with the first connecting rod 103 facilitates arranging a plurality of connecting branches 104 on the first connecting rod 103, and further facilitates arranging a plurality of cleaning members 12. It is convenient to adjust the extending direction of the projection of the cleaning member 12 in the rotation plane c of the main body portion 10 by adjusting the extending direction of the connecting branch 104. Furthermore, it is convenient to make the projections of the plurality of cleaning members 12 in the rotation plane c of the main body portion 10 be spaced apart along the rotation direction a of the main body within the above-mentioned fan-shaped area, reducing the interference between the plurality of cleaning members 12.

[0060] In some embodiments, as Figure 10 shown, at least part of the projection of the connecting branch 104 in the rotation plane c forms an acute angle B with the projection of the first connecting rod 103 in the rotation plane c.

[0061] The above settings facilitate the spaced arrangement of multiple connecting ends 13 along the rotation direction c of the main body 10. Therefore, it is convenient to achieve the spaced arrangement of the cleaning members 12 along the rotation direction c of the main body 10, which can reduce the interference between the cleaning members 12 and enable the cleaning members 12 to cover as much as possible the sector area corresponding to the included angle A1, improving the cleaning effect.

[0062] Optionally, the specific value of the acute angle B is not limited. For example, it can be 10°, 13°, 25°, 39°, 60°, 88°, 89°, etc.

[0063] In some embodiments, as Figure 11 shown, the second connecting portion 101 includes a second connecting rod 105. The projection of the second connecting rod 105 in the rotation plane c of the main body 10 extends along the vertical direction of the rotation axis b of the main body 10. The end and side of the second connecting rod 105 away from the main body 10 are provided with connecting ends 13.

[0064] The connecting end 13 is used to connect the cleaning member 12. The projection of the second connecting rod 105 in the rotation plane c of the main body 10 extends along the vertical direction of the rotation axis b of the main body 10, with a simple structure. The end and side of the second connecting rod 105 away from the main body 10 are provided with connecting ends 13, which is simple in structure and easy to implement, facilitating the setting of multiple connecting ends 13 on the second connecting rod 105. When mounting holes are provided on the connecting end 13 for mounting the cleaning member 12, the extending direction of the projection of the cleaning member 12 in the rotation plane c of the main body 10 can be adjusted by adjusting the axial direction of the mounting holes, reducing the interference between multiple cleaning members 12.

[0065] In some embodiments, at least part of the projection of the cleaning member 12 in the rotation plane c is set at an acute angle B with the projection of the second connecting rod 105 in the rotation plane c of the main body 10. The specific value of the acute angle B is not limited. For example, it can be 10°, 13°, 25°, 39°, 60°, 88°, 89°, etc.

[0066] In some embodiments, a plurality of connecting ends 13 are provided on the side of the second connecting rod 105, and at least part of the connecting ends 13 are arranged along the extending direction of the second connecting rod 105. This setting facilitates the setting of multiple connecting ends 13 on the second connecting rod 105, and thus facilitates the setting of multiple cleaning members 12. It should be noted that the projections of the multiple cleaning members 12 in the rotation plane c of the main body 10 are all located within the sector area corresponding to the included angle A1.

[0067] In other embodiments, the extending direction of the projection of the cleaning member in the rotation plane of the main body can also be set at an acute angle with the vertical direction of the rotation axis of the main body by adjusting the shape and size of the cleaning member.

[0068] In some embodiments, asFigure 9 As shown, a part of the plurality of first connecting parts 11 are integrally provided to form a third connecting part 1011 connected to the main body part 10, and a part of the plurality of first connecting parts 11 are integrally provided to form a fourth connecting part 1012 connected to the main body part 10. Both the third connecting part 1011 and the fourth connecting part 1012 extend along the circumferential direction of the main body part 10. The third connecting part 1011 and the fourth connecting part 1012 are arranged at intervals along the circumferential direction. A plurality of connecting ends 13 arranged along the circumferential direction are provided on the sides of the third connecting part 1011 and the fourth connecting part 1012 facing away from the main body part 10. Among them, the projections of all the connecting ends 13 in the rotation plane c of the main body part 10 are all located in a sector area with an included angle A1 less than 120°.

[0069] In some embodiments, the distribution mode of the cleaning parts 12 can also be adjusted by adjusting the structures of the third connecting part 1011 and the fourth connecting part 1012. For example, in Figure 9 the embodiment shown, the included angle A4 can be set not equal to the included angle A5, that is, the extending ranges of the third connecting part 1011 and the fourth connecting part 1012 along the circumferential direction of the main body part 10 are different; for another example (not shown in the figure), the number of connecting ends included on the sides of the third connecting part and the fourth connecting part facing away from the main body part can also be set differently, etc.

[0070] In other embodiments, the plurality of first connecting parts can be further divided into three groups or more than three groups. The plurality of first connecting parts in each group are integrally formed, and the projections of all the connecting ends in the rotation plane of the main body part are all located in a sector area with an included angle less than 120°.

[0071] In some embodiments, the cleaning branch 102 further includes a cleaning part 12.

[0072] It should be noted that the shapes and sizes of each cleaning part 12 can be the same or different, and the connection mode between the first connecting part 11 and the cleaning part 12 is not limited, such as bonding or detachable clamping, etc.

[0073] In some embodiments, when the cleaning branch 102 includes at least the first connecting portion 11, the angle formed by the line connecting the projection points of the two cleaning members 12 with the farthest distance on the rotation plane c and the rotation center of the rotation plane c can be made less than 120° by setting the structure of the first connecting portion 11 (for example, setting the specific structure of the connecting end 13 of the first connecting portion 11); it can also be achieved by setting the shape and size of the cleaning member so that the angle formed by the line connecting the projection points of the two cleaning members 12 with the farthest distance on the rotation plane c and the rotation center of the rotation plane c is less than 120°; or it can be achieved by simultaneously adjusting the shapes and sizes of multiple connecting ends 13 and multiple cleaning members 12 so that the angle formed by the line connecting the projection points of the two cleaning members 12 with the farthest distance on the rotation plane c and the rotation center of the rotation plane c is less than 120°.

[0074] In other embodiments, the cleaning branch includes a cleaning member, and the cleaning member is directly or indirectly connected to the main body portion.

[0075] Specifically, the cleaning branch does not include the first connecting portion. The side brush includes a main body portion and a cleaning member, and the cleaning member is connected to the main body portion. For example, in an application scenario, a plurality of connecting ends can be provided on the main body portion for connecting the cleaning members. This structure is simple and convenient for production and assembly.

[0076] In other embodiments, similar improvements can be made to the side brush, which will not be elaborated here.

[0077] In some embodiments, the cleaning member 12 includes a straight-line cleaning member 12.

[0078] The straight-line cleaning member 12 is convenient for installation, and it is convenient to limit and adjust the distribution range of the cleaning member 12 by setting connection structures such as the first connecting portion 11. Moreover, this structure is simple and convenient for mass production.

[0079] In other embodiments, the cleaning member may further include a curved cleaning member to cooperate with the specific structure of connection structures such as the first connecting portion to enable the projection of the cleaning member in the rotation plane to be located within the above-mentioned fan-shaped area.

[0080] In some embodiments, the shapes and sizes of multiple straight-line cleaning members are the same.

[0081] This setting is convenient for users to repair and replace the cleaning member, and it is also convenient for installation and mass production, which can reduce production costs.

[0082] In some embodiments, the first connecting portion 11 includes a deformable connecting claw. When the cleaning member 12 is cleaning close to the surface to be cleaned, the deformable connecting claw can undergo a certain degree of elastic deformation, reducing the risk of damage due to collision when the cleaning member 12 abuts against the surface to be cleaned.

[0083] The present application further provides a side brush, as Figures 1 to 11 shown. The side brush includes a main body portion 10 and at least two cleaning branch portions 102. The at least two cleaning branch portions 102 are directly or indirectly connected to the main body portion 10 at intervals; wherein, there is an included angle between the two cleaning branch portions 102 with the farthest distance, and the included angle is less than 120°.

[0084] The included angle less than 120° between the two cleaning branch portions 102 with the farthest distance can reduce the risk of the cleaning branch portions winding around slender objects such as hair and wires during the cleaning process, and improve the cleaning effect and user experience.

[0085] For the specific implementation manners and working principles of the main body portion 10 and the cleaning branch portions 102, reference can be made to the above embodiments, and details are not described herein again.

[0086] Different from the prior art, multiple cleaning branch portions of the present application are connected to the main body portion at intervals, which can improve the cleaning effect and cleaning range of the side brush; the included angle formed by the connection line between the projection points of the two cleaning branch portions with the farthest distance on the rotation plane and the rotation center of the rotation plane is less than 120°, which can reduce the risk of the cleaning branch portions winding around slender objects such as hair and wires when the side brush drives the cleaning branch portions to rotate. For example, it can reduce the risk of hair winding between multiple cleaning branch portions and affecting the cleaning effect. Therefore, this setting can also improve the convenience of cleaning and maintaining the cleaning branch portions; therefore, this setting can reduce the risk of the side brush winding around slender objects such as hair and wires, and improve the cleaning effect and user experience.

[0087] It should be noted that in the accompanying drawings herein, only the structural relationship and connection relationship of the products of the present application are shown, and the specific structural dimensions of the products of the present application are not limited thereby.

[0088] The above are only the implementation manners of the present application, and do not limit the patent scope of the present application. Any equivalent structural or equivalent process transformation made by using the content of the specification and drawings of the present application, or directly or indirectly applied in other related technical fields, shall be included in the patent protection scope of the present application by the same token.
