Description
Technical Field
[0001] This application relates to the technical field of cleaning equipment, and more specifically, to a side brush assembly and cleaning equipment. Background Technology
[0002] With the widespread use of smart home devices, self-cleaning devices have become an important tool for cleaning modern homes. Side brushes, as one of the core components of self-cleaning devices, are mainly used to clean the corners and edges of the area to be cleaned through continuous rotation.
[0003] In existing technologies, due to the increasing amount of pet or human hair falling from the area to be cleaned, and the fact that hair is very likely to be found in corners, hair is easily tangled in the side brush during the cleaning process of the corners, affecting its cleaning efficiency and even causing secondary pollution. Utility Model Content
[0004] The purpose of this application is to address the technical problems in related technologies by providing a side brush assembly and a cleaning device. The specific solution is as follows:
[0005] This application provides a side brush component, including:
[0006] Side brush base, used for connection to the drive assembly of the cleaning equipment;
[0007] A brush arm is connected to the side brush base; in the vertical direction, the end of the brush arm connected to the side brush base is higher than the end away from the side brush base; the projection of the brush arm onto the surface to be cleaned has a center line, which extends from the end connected to the side brush base to the end away from the side brush base.
[0008] A brush component is connected to the brush arm; in the vertical direction, the end of the brush component connected to the brush arm is higher than the end away from the brush arm.
[0009] Wherein, along the rotation direction of the brush arm, the downstream edge line of the projection of the brush arm onto the surface to be cleaned is a spiral line. The spiral line is the trajectory formed by a point moving radially away from a fixed point at a constant speed while rotating around the fixed point at a fixed angular velocity.
[0010] In some embodiments, the end of the brush member away from the brush arm has an angled structure.
[0011] In some embodiments, the angle between the inclined surface of the beveled structure and the extension direction of the brush is greater than 30 degrees and less than 90 degrees.
[0012] In some embodiments, the brush member has a long side and a short side extending away from one end of the brush arm, the long side being downstream of the brush arm in the direction of rotation relative to the short side.
[0013] In some embodiments, the brush element is made of an antistatic material.
[0014] In some embodiments, the brush includes conductive particles.
[0015] In some embodiments, the end of the brush arm connected to the brush member has a protrusion to prevent foreign objects from getting tangled in the side brush base.
[0016] In some embodiments, the end of the protrusion away from the brush base has an arc-shaped structure.
[0017] In some embodiments, a gap exists between the protrusion and the brush.
[0018] In some embodiments, the long side and / or the short side are inclined relative to the vertical direction.
[0019] In some embodiments, along the rotation direction of the brush arm, the upper edge of the long side and / or the short side is located downstream of the lower edge.
[0020] In some embodiments, the end of the brush arm away from the side brush base has an arc-shaped protrusion facing the surface to be cleaned.

[0022] Compared with the prior art, this application has at least the following technical effects:
[0023] This application discloses a side brush assembly and cleaning device, wherein, along the rotation direction of the brush arm, the downstream edge line of the projection of the brush arm onto the surface to be cleaned is a spiral. The spiral is a trajectory formed by a point moving radially away from a fixed point at a uniform speed while simultaneously rotating around that fixed point at a fixed angular velocity. By setting the brush arm to a spiral structure, the brush arm can use centrifugal force to dislodge the hair to be cleaned during rotational cleaning, preventing hair from becoming entangled on the brush arm. Furthermore, the spiral structure of the brush arm allows its radius to change uniformly after rotation, making it less likely to agitate particulate matter and thus increasing cleaning efficiency.

[0034] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0039] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a product or device that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a product or device. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the product or device that includes that element.
[0040] In related technologies, cleaning equipment includes a main cleaning component and a side brush component. When performing a cleaning task, the main cleaning component cleans debris along the cleaning path, while the side brush component cleans debris within or outside the cleaning path. However, because the side brush component in these technologies lacks a hair-tangle-free structure, hair from the area to be cleaned easily gets tangled on it, affecting its cleaning efficiency and potentially causing secondary contamination during subsequent cleaning.
[0041] To this end, this application provides a side brush assembly, comprising: a side brush base for connection to a drive assembly of a cleaning device; a brush arm connected to the side brush base; in the vertical direction, the end of the brush arm connected to the side brush base is higher than the end away from the side brush base; the projection of the brush arm onto the surface to be cleaned has a center line, the center line extending from the end connected to the side brush base to the end away from the side brush base; a brush member connected to the brush arm; in the vertical direction, the end of the brush member connected to the brush arm is higher than the end away from the brush arm; wherein, along the rotation direction of the brush arm, the downstream edge line of the projection of the brush arm onto the surface to be cleaned is a spiral, the spiral being a trajectory formed by a point moving radially away from a fixed point at a uniform speed while simultaneously rotating around the fixed point at a fixed angular velocity. This application also provides a cleaning device, the cleaning device including a drive assembly and the side brush assembly as described above, the drive assembly being configured to drive the side brush assembly to rotate.
[0042] This application utilizes a helical brush arm structure, allowing the brush arm to use centrifugal force to scatter hair during rotation, preventing hair from becoming entangled on the brush arm. Furthermore, the helical structure ensures a uniform radius change during rotation, minimizing the dispersal of particulate matter. The helical arrangement of the brush arms ensures that the effective contact point sweeps across the entire disk surface from the center outwards at a constant radial speed during rotation, increasing cleaning efficiency. Moreover, the interval between adjacent rotations on the helix is constant, resulting in an almost uniform number of radial passes per unit area. This prevents over- or under-cleaning phenomena such as three passes in the center and only one pass on the outer ring, leading to more even cleaning.
[0043] The optional embodiments of this application are described in detail below with reference to the accompanying drawings.
[0044] like Figure 1As shown, this application embodiment provides a side brush assembly, including a side brush base 10, a brush arm 20, and a brush component 30. The side brush base 10 is connected to a drive assembly on a cleaning device, and the side brush base 10 rotates under the drive of the drive assembly. One end of the brush arm 20 is connected to the side brush base 10; in the vertical direction, the end of the brush arm 20 connected to the side brush base 10 is higher than the end away from the side brush base 10. It is understood that the connection between the end of the brush arm 20 and the side brush base 10 can be detachable or integral, and there is no limitation thereto. The brush component 30 is connected to the end of the brush arm 20 away from the side brush base 10, and the end of the brush component 30 connected to the brush arm 20 is higher than the end away from the brush arm 20. Along the rotation direction of the brush arm 20, the downstream edge line of the projection of the brush arm 20 onto the surface to be cleaned is a spiral line, which is a trajectory formed by a point moving radially away from a fixed point at a constant speed while rotating around the fixed point at a fixed angular velocity. The surface to be cleaned is the surface on which the cleaning equipment performs its cleaning task, such as a level ground or a non-level surface.
[0045] The aforementioned spiral is the trajectory produced by a point moving radially away from a fixed point at a constant velocity while simultaneously rotating around that fixed point at a fixed angular velocity. For example... Figure 3 As shown, the polar equation of the spiral is:
[0046] r = a + bθ
[0047] Where a and b are both real numbers. When θ = 0, a is the distance from the starting point to the origin of the polar coordinates. dr / dθ = b, where b is the value that increases with each unit angle r of the helix. When θ > 0, a is equivalent to a rotating helix, while parameter b controls the distance between two adjacent curves.
[0048] This application proposes to design the brush arm as a spiral structure, which allows the brush arm to use centrifugal force to shake off the hair to be cleaned during rotation, preventing hair from getting tangled on the brush arm. Because the spiral structure of the brush arm allows its radius to change uniformly after rotation, it is less likely to fly up particulate matter, thereby increasing cleaning efficiency.
[0049] In some embodiments, such as Figure 2 As shown, the side brush base 10 includes a housing 11 and a connector 12. The connector 12 is detachably connected to the housing 11. The outer surface of the housing 11 is provided with a connection position 111 for connecting to the brush arm 20. The connector 12 is provided with a connection part 121, which is connected to the drive shaft of the cleaning equipment drive assembly. Under the drive of the drive shaft, the side brush base 10 is rotated.
[0050] In some embodiments, the number of brush arms 20 is typically 2-5, such as 3 or 4, and the brush arms 20 are evenly distributed on the outer periphery of the side brush base 10. Each brush arm 20 forms at least part of a spiral, and its radius changes uniformly after rotation, making it less likely to fly up particulate debris and able to shake off hair, preventing hair entanglement and reducing cleaning efficiency. Optionally, the brush arms 20 are made of rubber strip material, which has a certain degree of flexibility to avoid scratching the floor or damaging surrounding equipment when performing cleaning tasks.
[0051] In some embodiments, such as Figure 1 As shown, the end of the brush arm away from the side brush base has an arc-shaped protrusion 23 facing the surface to be cleaned. The arc-shaped protrusion 23 can improve the overall strength of the brush arm 20 and increase the pressure of the brush on the ground, thereby improving the cleaning effect.
[0052] In some embodiments, such as Figure 3 As shown, the side brush assembly also includes a brush member 30, which is connected to the end of the brush arm 20 away from the side brush base 10. The brush member 30 can be a rubber strip or a brush thread bundle, wherein the end of the brush member 30 away from the brush arm 20 has an angled structure 31. Figure 3 The direction indicated by the middle arrow is the rotation direction of the side brush assembly. When performing a cleaning task, as the side brush assembly rotates counterclockwise, the long side 32 of the brush 30 contacts the hair first, followed by the shorter side 33. This makes it less likely for the hair to get stuck, reducing the probability that the brush 30 will be tangled in the hair.
[0053] Optionally, the angle c between the beveled surface of the angled structure 31 and the extension direction of the brush is greater than 30 degrees and less than 90 degrees. For example, the angle c can be 45 degrees, 50 degrees, 60 degrees, etc. The angled structure 31 allows the longer side to contact the hair first, followed by the shorter side, thus enhancing the anti-tangling effect. If the angle is too large, such as 90 degrees, the anti-tangling effect will be reduced; if the angle is too small, such as 10 degrees, the cleaning effect will be affected.
[0054] Specifically, the brush member 30 has a long side 32 and a short side 33 extending from one end of the brush arm 20 away from the other end of the brush arm 20, with the long side 32 located downstream of the short side 33 in the rotation direction of the brush arm 20. For example... Figure 3 As shown, in the rotation direction AB of the brush arm 20, A is the upstream direction of rotation, and B is the downstream direction of rotation. The included angle c is the angle formed by the long side 32 of the brush 30 and the inclined surface at the end of the brush 30. The smaller the included angle c, the less likely it is to get caught in the hair, and the lower the probability of the brush 30 being entangled in hair.
[0055] In some embodiments, such as Figure 4As shown, the long side 32 is inclined relative to the vertical direction MN. Specifically, along the rotation direction of the brush arm 20, the upper edge 321 of the long side 32 is located downstream of the lower edge 322 of the long side. During cleaning, as the side brush assembly rotates counterclockwise, the upper edge 321 of the long side contacts the hair first, followed by the lower edge 322, making it less likely for hair to get stuck and reducing the probability of the brush 30 becoming entangled in hair. In addition, this inclined structure also reduces wind resistance when the brush 30 rotates, thereby saving energy.
[0056] In some embodiments, such as Figure 4 As shown, the short side 33 can also be tilted relative to the vertical direction MN. Specifically, along the rotation direction of the brush arm 20, the upper edge 331 of the short side 33 is located downstream of the lower edge 332 of the short side. This allows hair to be guided and prevented from getting tangled in the brush 30.
[0057] In some embodiments, such as Figure 5 As shown, the end of the brush arm 20 connected to the brush component 30 has a protrusion 21 to prevent foreign objects from getting tangled in the side brush base. The protrusion 21 blocks hair from moving towards the side brush base 10, preventing it from getting tangled in the drive portion of the side brush assembly. Furthermore, the end of the protrusion 21 away from the side brush base 10 has an arc-shaped structure. The arc-shaped structure reduces the scraping between the protrusion 21 and the hair, further reducing the probability of hair tangling. Optionally, as... Figure 5 As shown, the protrusion 21 can be located on the side of the brush 30 away from the surface to be cleaned, that is, the protrusion 21 can at least partially overlap with the projection of the brush 30 onto the surface to be cleaned. Optionally, as... Figure 6 As shown, the protrusion 21 can also be located downstream of the connection between the brush arm 20 and the brush 30, that is, the projection of the protrusion 21 and the brush 30 on the surface to be cleaned does not overlap.
[0058] In some embodiments, a gap 22 is provided between the protrusion 21 and the brush member 30. The gap 22 has a certain preset width, which further allows hair to pass through and prevents hair from getting stuck at the connection between the brush member 30 and the brush arm 20.
[0059] Combination Figure 1 It is understandable that, in the vertical direction, the end of the brush arm 20 connected to the side brush base 10 is higher than the end away from the side brush base. The brush arm 20 extends in a generally downward direction to raise the side brush base 10 as high as possible when the brush 30 can contact the surface to be cleaned, thereby improving the passability of the side brush assembly.
[0060] In some embodiments, combined with Figure 1It is understandable that, in the vertical direction, the end of the brush 30 connected to the brush arm 20 is higher than the end away from the brush arm 20. The brush 30 extends in a roughly downward direction to enhance the contact pressure between the end of the brush 30 and the surface to be cleaned, thereby increasing the cleaning force of the brush and improving cleaning efficiency.
[0061] In some embodiments, the brush element 30 may be made of an antistatic material. Optionally, the brush element 30 may be made of PA66, nylon, or rubber. By using an antistatic material, the brush element 30 is less likely to generate static electricity and attract hair during its rotation, thus reducing the possibility of hair adhering to the brush element 30.
[0062] In some embodiments, the brush 30 includes conductive particles. This reduces the surface resistance of the brush 30, and the static electricity generated during brushing interference with the ground is released to the ground, making it less likely for hair to adhere to the brush 30.
[0063] This application also provides a cleaning device, including: a drive component and a side brush component as described in any of the above. When performing a cleaning task, the cleaning device drives the side brush component to rotate through the drive component to extend the cleaning beyond the main body of the cleaning device, thereby cleaning corners and edges of obstacles and improving the cleaning efficiency of the cleaning device.
[0064] This application discloses a side brush assembly and cleaning device, wherein the projection of the brush arm of the side brush assembly onto the surface to be cleaned is a spiral. This allows the brush arm to use centrifugal force to shake off hair during rotation, preventing hair from becoming entangled on the brush arm and reducing the risk of secondary contamination. The spiral structure of the brush arm ensures that its radius changes uniformly after rotation, making it less likely to fly up particulate matter and thus increasing cleaning efficiency.
[0065] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. For the systems or apparatus disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the descriptions are relatively simple, and relevant parts can be referred to the method section.
[0066] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
