DETAILED DESCRIPTION

[0031] In order to facilitate the understanding of the present application, the present application will be described in more detail below in combination with the drawings and specific embodiments. It should be noted that when an element is described as being "connected" to another element, it can be directly on the other element or one or more intervening elements can be present therebetween. The terms "upper", "lower", "left", "right", "upper end", "lower end", "top" and "bottom" and the like used in the present specification indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application. In addition, the terms "first", "second", and the like are only for the purpose of description and cannot be understood as indicating or implying relative importance.

[0032] Unless otherwise defined, all technical and scientific terms used in the present disclosure have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0033] In the prior art, the side brush of the cleaning robot usually adopts a three-claw side brush structure. When rotating, the three claws are uniformly distributed, and the trajectories of each claw in the rotating process can be connected to each other, thereby forming an approximately circular coverage area. When the flexible garbage such as hair and thread on the ground contacts the three-claw structure, due to the high coverage rate and the relatively small gap between the claws, in the rotating process, the hair at the root is subjected to the action of the rotating force, and is continuously wound between the three claws, and finally forms a lump-shaped winding at the root of the claw, which causes the flexible garbage such as hair and thread to be difficult to shake off, which not only affects the ground cleaning effect, but also increases the cleaning and maintenance cost of the side brush.

[0034] Based on this, the embodiments of the present application provide a side brush and a cleaning robot to solve the technical problem that the flexible garbage such as hair and thread is easily wound on the side brush in the prior art. In the following, the side brush and the cleaning robot provided by the embodiments of the present application will be described in detail. Figures 1 to 7 The side brush and the cleaning robot provided by the embodiments of the present application are described in detail.

[0035] Please refer to Figure 1 and Figure 2 The embodiments of the present application provide a cleaning robot 100, which includes a body 10, a roller brush 20 and a side brush 30.

[0036] The cleaning robot 100 can move on a surface to be cleaned to clean the area passed thereby, wherein the surface to be cleaned can be the surface of the ground, carpet or blanket, etc. The cleaning robot 100 can be in a substantially circular shape, but is not limited thereto, for example, the cleaning robot 100 can also be in a D-shaped, square, etc.

[0037] The cleaning robot 100 is usually provided with the roller brush 20 and the side brush 30. The roller brush 20 is usually installed at the central position of the bottom of the body 10, and through the rotation of the roller brush 30, the garbage on the surface to be cleaned can be gathered and swept into the dust box of the cleaning robot 100. The side brush 30 is usually installed at the edge position of the bottom of the body 10, and partially extends beyond the outline of the body 10, so that through the rotation of the side brush 30, the garbage in the edge area of the body 10 and the corner and other narrow areas can be conveniently cleaned, and the garbage is pushed to the working range of the roller brush 20.

[0038] Please refer to Figure 3 and Figure 4In some embodiments, the side brush 30 comprises a base 31 and a main brush structure 32, the main brush structure 32 comprises a root 320, a first brush handle 321, a second brush handle 322 and a main cleaning strip 323, the root 320 is connected with the base 31, the first brush handle 321 and the second brush handle 322 are both connected with an end of the root 320 away from the base 31 and extend outwardly away from the base 31, and the first brush handle 321 and the second brush handle 322 are arranged at an angle, and the end of the first brush handle 321 away from the base 31 and the end of the second brush handle 322 away from the base 31 are respectively connected with the main cleaning strip 323.

[0039] The base 31 is rotatably installed at the bottom of the machine body 10, and the base 31 is optionally in a substantially annular structure, and a rotation shaft hole 310 is formed on the side of the base 31 facing the machine body 10, and the machine body 10 is provided with a transmission shaft (not shown) in transmission cooperation with the base 31, and when installing, the rotation shaft hole 310 on the base 31 is aligned with the transmission shaft on the machine body 10, and the transmission shaft is inserted into the rotation shaft hole 310, and the installation of the side brush 30 on the machine body 10 can be completed. When installed, the rotation of the transmission shaft on the machine body 10 can drive the base 31 and the main brush structure 32 to rotate as a whole, so as to realize the cleaning operation on the surface to be cleaned.

[0040] The main brush structure 32 can have one or more, and the main brush structure 32 comprises the root 320, the first brush handle 321, the second brush handle 322 and the main cleaning strip 323, and the root 320 is fixedly connected with the base 31, for example, the root 320 can be connected to the side of the base 31. The first brush handle 321 and the second brush handle 322 can be in a substantially rod-like structure, and the first brush handle 321 and the second brush handle 322 are arranged at an angle, and optionally, the angle between the first brush handle 321 and the second brush handle 322 can be between 0-180°.

[0041] The root 320, the first brush handle 321 and the second brush handle 322 form a substantially "Y" shaped structure, and the main cleaning strip 323 has two, and the main cleaning strip 323 is in a strip-like structure, one of the main cleaning strips 323 is installed at the end of the first brush handle 321, and the other main cleaning strip 323 is installed at the end of the second brush handle 322. It can be understood that after installation, the two main cleaning strips 323 are arranged at an angle, and in the process of rotating the side brush 30, the main cleaning strips 323 on the first brush handle 321 and the second brush handle 322 can be in contact with the surface to be cleaned to clean the garbage on the surface to be cleaned, so as to guarantee the cleaning efficiency and cleaning effect.

[0042] Optionally, the base 31, the root 320, the first brush handle 321 and the second brush handle 322 can be made of plastic or metal materials, for example, the base 31 can be made of ABS (acrylonitrile butadiene styrene) material. The base 31, the root 320, the first brush handle 321 and the second brush handle 322 can be integrally formed to ensure the structural strength, and in addition, the main brush structure 32 can be detachably mounted on the side of the base 31, that is, the root 320 of the main brush structure 32 can be detachably mounted on the side of the base 31 by plug-in, threaded connection or the like, so as to facilitate maintenance and replacement of the main brush structure 32.

[0043] Optionally, the root 320 of the main brush structure 32 can also be mounted on the base 31 in a plug-in or sleeved manner. For example, the base 31 can be provided with a mounting hole, and one end of the root 320 facing the base 31 is inserted into the mounting hole to realize mounting of the root 320 on the base 31; or the base 31 can include a cover body that is closed from top to bottom, the cover body is internally provided with a mounting shaft and a root avoiding hole, and the main brush structure 32 is arranged on the side of the mounting hole sleeve that is adapted to the mounting shaft, that is, the root 320 is arranged on the side of the mounting hole sleeve away from the brush handle, the main brush structure 32 is mounted on the base 31 through the alignment mounting of the mounting hole sleeve and the mounting shaft, and the root 320 or the first brush handle 321 and the second brush handle 322 extend out of the base through the root avoiding hole. Here, the mounting and cooperation relationship between the main brush structure 32 and the base 31 is not limited.

[0044] The main cleaning strip 323 can be a brush. Optionally, the main cleaning strip 323 can be made of nylon material. The nylon material is relatively soft, can better adhere to the surface to be cleaned, and can guarantee the cleaning effect of the floor. In addition, the surface of the nylon material is relatively smooth, which can reduce the entanglement of flexible garbage such as hair and thread. It can be understood that in other embodiments, the main cleaning strip 323 can also be made of polyester fiber or other synthetic fibers.

[0045] In the embodiment, the main brush structure 32 gradually extends from the root 320 to the first brush handle 321 and the second brush handle 322 arranged at an angle, forming an open structure. Compared with the multi-claw edge brush 30 (such as a three-claw) in the prior art, the contact points of flexible garbage such as hair and thread with the edge brush 30 are relatively small in the embodiment, which reduces the risk of entanglement of flexible garbage such as hair and thread.

[0046] In addition, since the contact points of flexible garbage such as hair and thread with the edge brush 30 are relatively small, the friction provided by the edge brush 30 for the flexible garbage such as hair and thread is small. In the process of rotation of the edge brush 30, the centrifugal force can more effectively act on the flexible garbage such as hair and thread, and the flexible garbage such as hair and thread can be thrown away, thereby avoiding the entanglement of the flexible garbage such as hair and thread on the main brush structure 32 to affect the cleaning effect, reducing the cleaning and maintenance cost of the edge brush 30, and prolonging the service life of the edge brush 30.

[0047] Referring to Figure 4 In some embodiments, the included angle between the first brush handle 321 and the second brush handle 322 is between 30° and 80°, for example, the included angle a between the first brush handle 321 and the second brush handle 322 can be 30°, 50°, 60°, 80°, etc. By setting the included angle a between the first brush handle 321 and the second brush handle 322 to be between 30° and 80°, it can not only avoid that the included angle a between the first brush handle 321 and the second brush handle 322 is too small to affect the cleaning coverage and cleaning efficiency, but also avoid that the included angle a between the first brush handle 321 and the second brush handle 322 is too large to increase the risk of entanglement of flexible garbage such as hair and thread.

[0048] In other words, if the included angle a between the first brush handle 321 and the second brush handle 322 is small (less than 30°), the main cleaning strips 323 on the first brush handle 321 and the main cleaning strips 323 on the second brush handle 322 are relatively close, and the cleaning tracks of the main cleaning strips 323 on the first brush handle 321 and the second brush handle 322 when rotating will have a large degree of overlap, so that in a unit rotation period, the effective area that the main brush structure 32 can actually clean is relatively narrow, and the cleaning efficiency is relatively low.

[0049] If the included angle between the first brush handle 321 and the second brush handle 322 is large (greater than 80°), the direction of the centrifugal force provided by the first brush handle 321 and the second brush handle 322 when rotating is relatively dispersed, and the centrifugal force cannot be effectively utilized to throw the flexible garbage such as hair and thread on the main brush structure 32, resulting in that more flexible garbage such as hair and thread is entangled on the main brush structure 32, which affects the cleaning efficiency and service life of the side brush 30.

[0050] Therefore, in the embodiment, by setting the included angle a between the first brush handle 321 and the second brush handle 322 to be between 30° and 80°, the entanglement of hair on the main brush structure 32 can be greatly reduced while the cleaning coverage and cleaning efficiency are guaranteed.

[0051] Referring to Figure 5 In some embodiments, the first brush handle 321 and the second brush handle 322 are both curved towards the rotation direction of the base 31.

[0052] In the embodiment, the first brush handle 321 and the second brush handle 322 are both arc-shaped structures and are curved towards the rotation direction of the side brush 30, where the rotation direction is the rotation direction of the side brush 30 when performing the cleaning operation, specifically, when the rotation direction of the side brush 30 when performing the cleaning operation is the clockwise direction, the first brush handle 321 and the second brush handle 322 are curved towards the clockwise direction, and when the rotation direction of the side brush 30 when performing the cleaning operation is the counterclockwise direction, the first brush handle 321 and the second brush handle 322 are curved towards the counterclockwise direction, as shown in Figure 5As shown, the rotation direction of the side brush 30 during the cleaning operation is counterclockwise, and the first brush handle 321 and the second brush handle 322 also bend in the counterclockwise direction, which makes the included angle between the centrifugal force direction provided by the rotation of the side brush 30 and the tangent direction of the arc-shaped structure smaller. The hair wrapped around the first brush handle 321 and the second brush handle 322 is more easily thrown along the path of the arc-shaped structure under the push of the centrifugal force, further reducing the entanglement of hair, threads, and other flexible garbage on the first brush handle 321 and the second brush handle 322, and avoiding the impact of the entanglement of hair, threads, and other flexible garbage on the first brush handle 321 and the second brush handle 322 on the cleaning effect.

[0053] Please refer to Figure 6 In some embodiments, the included angle β between the length direction of the main cleaning strip 323 and the horizontal direction is between 30° and 60°, for example, the included angle β between the length direction of the main cleaning strip 323 and the horizontal direction can be 30°, 40°, 50°, 60°, etc.

[0054] Specifically, the horizontal direction generally refers to the direction of the plane on which the surface to be cleaned is located. It can be understood that when the included angle β between the length direction of the main cleaning strip 323 and the horizontal direction is relatively small, the pressure of the main cleaning strip 323 on the surface to be cleaned is relatively small, and when the included angle β between the length direction of the main cleaning strip 323 and the horizontal direction is relatively large, the pressure of the main cleaning strip 323 on the surface to be cleaned is relatively large.

[0055] In this embodiment, by setting the included angle β between the length direction of the main cleaning strip 323 and the horizontal direction to be between 30° and 60°, the main cleaning strip 323 and the surface to be cleaned are always in proper pressure contact, ensuring that the main cleaning strip 323 can effectively clean and gather small particulate matter and other garbage on the surface to be cleaned, and improving the cleaning ability of the side brush 30.

[0056] In other words, if the included angle β between the length direction of the main cleaning strip 323 and the horizontal direction is too small (less than 30°), the pressure of the main cleaning strip 323 on the surface to be cleaned will not be enough. When cleaning the surface to be cleaned, due to the insufficient contact pressure of the main cleaning strip 323 on the surface to be cleaned, it cannot generate enough friction with the particulate matter, making it difficult to clean the fine particulate matter. Especially for some uneven surfaces to be cleaned, the surface to be cleaned often has some gaps or small pits. When the contact pressure of the main cleaning strip 323 on the surface to be cleaned is insufficient, the main cleaning strip 323 cannot penetrate into the gaps or small pits of the surface to be cleaned, making it difficult to clean the small particulate matter.

[0057] If the angle β between the length direction of the main cleaning strip 323 and the horizontal direction is too large (greater than 60°), the angle that is too large will cause the main cleaning strip 323 to bear too much pressure when pressing the ground, which is easy to cause the main cleaning strip 323 to be bent and deformed, accelerate the damage of the main cleaning strip 323, and increase the maintenance and replacement cost of the side brush 30.

[0058] Therefore, in the embodiment, the angle β between the length direction of the main cleaning strip 323 and the horizontal direction is set to be between 30° and 60°, which can not only avoid the insufficient contact pressure of the main cleaning strip 323 on the cleaning surface to affect the cleaning effect of the surface to be cleaned, but also avoid the excessive contact pressure of the main cleaning strip 323 on the cleaning surface to cause the deformation and damage of the main cleaning strip 323.

[0059] Please refer to Figure 4 and Figure 7 In some embodiments, the first brush handle 321 and the second brush handle 322 are both spirally curved along the length direction thereof (see Figure 5 During the rotation of the first brush handle 321 and the second brush handle 322, the first brush handle 321 and the second brush handle 322 that are spirally curved cause the bottom of the main cleaning strip 323 to produce a certain torsion angle when contacting the surface to be cleaned, and then the bristles at the bottom of the main cleaning strip 323 are spread out, thereby increasing the laying area of the bristles at the bottom of the main cleaning strip 323, increasing the contact area of the bristles at the bottom of the main cleaning strip 323 with the surface to be cleaned, thereby covering a larger cleaning range, ensuring the gathering effect of the tiny particles, reducing the possibility of the tiny particles flying and scattering, and improving the cleaning efficiency and cleaning effect.

[0060] As Figure 7 shown, in some embodiments, the angle θ between the end face of the first brush handle 321 and the horizontal direction, and the angle between the end face of the second brush handle 322 and the horizontal direction are both between 5° and 20°, for example, 5°, 10°, 15°, 20°, and the like. It can be understood that the angle θ between the end face of the first brush handle 321 and the horizontal direction, and the angle between the end face of the second brush handle 322 and the horizontal direction do not require being completely different, but only need to be between 5° and 20°.

[0061] Specifically, by the first brush handle 321 and the second brush handle 322 being spirally curved along the length direction thereof, the end face of the first brush handle 321 and the end face of the second brush handle 322 can be 5°-20° with the horizontal direction. When the end face of the first brush handle 321 and the end face of the second brush handle 322 are 5°-20° with the horizontal direction, the bottom of the main cleaning strip 323 will produce a proper torsion angle when contacting the ground, so that the bristles at the bottom of the main cleaning strip 323 can be fully spread out.

[0062] In other words, if the included angle between the end surface of the first brush handle 321 and the end surface of the second brush handle 322 and the horizontal direction is too small (e.g., less than 5°), the angle of the bottom of the main cleaning strip 323 to twist after contacting the ground is small, which is not conducive to the full expansion of the bristles at the bottom of the main cleaning strip 323. If the included angle between the end surface of the first brush handle 321 and the end surface of the second brush handle 322 and the horizontal direction is too large (e.g., greater than 20°), the main cleaning strip 323 will be subjected to a large torsional force and frictional force, resulting in bending and damage, affecting its service life.

[0063] Please refer to Figure 3 and Figure 4 In some embodiments, the side brush 30 further comprises a secondary brush structure 33, which comprises a base 330 and a secondary cleaning strip 331, the base 330 is arranged on the base 31, and the secondary cleaning strip 331 is connected to one end of the base 330 away from the base 31.

[0064] As shown in Figure 4 , the base 330 can be an integral structure with the base 31 to ensure its structural strength. In addition, the base 330 can also be detachably mounted on the base 31 in a plug-in or threaded connection manner to facilitate maintenance and replacement of the secondary brush structure 33. Alternatively, the base 330 can also be installed on the base 31 in a plug-in or sleeved manner.

[0065] The secondary cleaning strip 331 can be a brush. Alternatively, the secondary cleaning strip 331 can be made of nylon material, polyester fiber or other synthetic fiber. The nylon material is relatively soft, which can better adhere to the surface to be cleaned, ensuring the cleaning effect of the floor, and the surface of the nylon material is relatively smooth, which can reduce the entanglement of flexible garbage such as hair and thread. It can be understood that in other embodiments, the secondary cleaning strip 331 can also be made of polyester fiber or other synthetic fiber.

[0066] The secondary brush structure 33 can be arranged on the side of the base 31, one end of the secondary cleaning strip 331 is connected to the base 330, and the other end extends to the outer circumferential side of the base 31. Compared with the main brush structure 32, the secondary brush structure 33 is smaller in size and closer to the base 31. During the rotation of the side brush 30, the secondary cleaning strip 331 is mainly used to clean the flexible garbage such as hair and thread around the periphery of the base 31, preventing the flexible garbage such as hair and thread from entering the base 31 and winding around the transmission shaft on the robot body 10 to cause the transmission shaft to stop, and ensuring the normal operation of the cleaning robot 100.

[0067] It can be understood that in other embodiments, a sealing structure can also be provided to prevent flexible garbage such as hair and thread from entering the base 31, and the secondary brush structure 33 can be omitted at this time.

[0068] In some embodiments, the roots 320 and the bases 330 are respectively arranged on opposite sides of the base 31, that is, the main brush structure 32 and the auxiliary brush structure 33 are respectively arranged on opposite sides of the side of the base 31, the distance between the main brush structure 32 and the auxiliary brush structure 33 is relatively far, so as to avoid the mutual interference caused by the close distance between the main brush structure 32 and the auxiliary brush structure 33, and reduce the influence on the gravity center of the side brush 30, so as to ensure that the side brush 30 can maintain good balance and stability during rotation.

[0069] In some embodiments, the length of the auxiliary cleaning strip 331 is between 2mm and 15mm, for example, 2mm, 5mm, 10mm, 15mm, etc.

[0070] In the present embodiment, the auxiliary cleaning strip 331 is configured to an appropriate length, which can avoid the influence on the cleaning effect of flexible garbage such as hair and thread caused by too short length of the auxiliary cleaning strip 331, and can also avoid the deformation damage caused by too long length of the auxiliary cleaning strip 331 when being in contact with the surface to be cleaned.

[0071] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; under the idea of the present application, the technical features in the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other changes of different aspects of the present application as described above, which are not provided in details for simplicity; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
