Description

Technical Field

[0001] The utility model relates to a side sweeping component and cleaning equipment, belonging to the technical field of cleaning equipment. Background Art

[0002] As a new type of cleaning appliance, sweeping robots are becoming more and more popular among users, especially intelligent sweeping, washing and mopping robots, whose edge cleaning function is a necessary function. The side sweeping component can recycle the garbage around the body into the middle sweeping range, and use the bristles on the side sweeping component to clean the corners and edges. Existing sweeping robots generally have an outward-expanding side sweeping component to obtain a larger coverage area and improve cleaning efficiency.

[0003] However, although the outward-extended side sweeping component has a higher cleaning efficiency, it is difficult to avoid the risk of being entangled by hair. In severe cases, it may cause the motor to be blocked, causing the sweeping robot to stop working.

[0004] In view of this, it is indeed necessary to propose a side sweeping component and a cleaning device to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a side sweeping component, which can prevent the side sweeping component from being entangled by hair and improve the cleaning efficiency.

[0006] To achieve the above-mentioned purpose, the utility model provides a side sweeping assembly, which is applied to cleaning equipment, including a mounting portion and at least one cleaning member, the mounting portion having a central axis extending in a vertical direction, each of the cleaning members comprising a brush arm and bristles, the brush arms being respectively connected to the mounting portion and the bristles, the bristles comprising a connecting end close to the brush arm and a cleaning end away from the brush arm, the side sweeping assembly having a first working position, in which the distance between the cleaning end and the central axis is smaller than the distance between the connecting end and the central axis.

[0007] As a further improvement of the present invention, the side sweeping assembly has a second working position, and in the vertical direction, the height of the second working position is smaller than the height of the first working position; and, at the second working position, the distance between the cleaning end and the central axis is greater than the distance between the connecting end and the central axis.

[0008] As a further improvement of the present invention, the cleaning end has a first extension axis, and the angle between the first extension axis and the surface to be cleaned is an acute angle.

[0009] As a further improvement of the present invention, the side sweeping assembly can rotate circumferentially along the central axis and has a rotation direction, the bristles are inclined in a direction away from the brush arm and have an inclined direction, and the rotation direction is opposite to the inclined direction.

[0010] As a further improvement of the utility model, the orthographic projection of the bristles on the surface to be cleaned is arc-shaped and the arc surrounds the mounting portion.

[0011] As a further improvement of the present invention, the brush arm includes a first end connected to the mounting portion and a second end connected to the bristles, the second end having a second extension axis, and from the connecting end to the cleaning end, the bristles extend in a direction away from the second extension axis and in a direction away from the mounting portion.

[0012] As a further improvement of the present invention, the brush arm is bent in a direction away from the central axis to form an arc-shaped portion, the arc-shaped portion is located between the first end and the second end, and the distance between the arc-shaped portion and the central axis is greater than the distance between the first end / the second end and the central axis.

[0013] As a further improvement of the present invention, the brush arm is rotatably connected to the bristles, and when the cleaning member rotates along the central axis following the mounting portion, the brush arm rotates before the bristles.

[0014] As a further improvement of the present invention, the bristles are made of soft material, and the length of the bristles is greater than the length of the brush arm. When the bristles rotate along the central axis with the brush arm, the connecting end rotates before the cleaning end.

[0015] To achieve the above-mentioned purpose, the utility model provides a cleaning device, comprising a main body and the side-sweeping assembly as described above, wherein the side-sweeping assembly is connected to the main body via the mounting portion.

[0016] The beneficial effect of the utility model is that the side sweeping assembly of the utility model divides the bristles into a connecting end close to the brush arm and a cleaning end far away from the brush arm, and the distance between the cleaning end and the central axis is smaller than the distance between the connecting end and the central axis. By arranging the cleaning end closer to the central axis than the connecting end, the rotation diameter of the bristles presents a structure that is small at the bottom and large at the top, that is, an inverted cone structure, without reducing the cleaning coverage of the bristles. When the hair is entangled on the cleaning part, the diameter that needs to be wound becomes larger, thereby preventing the hair from continuing to climb up along the bristles and entangle, thereby improving the user experience.

[0026] Embodiment 1

[0027] See also Figures 1 to 6 As shown, the utility model discloses a side sweeping assembly 100, which can be applied to a cleaning device (not shown) to clean a surface to be cleaned, and can clean along an edge or along a wall.

[0028] The side sweeping assembly 100 includes a mounting portion 10 and at least one cleaning member 20. In this embodiment, the side sweeping assembly 100 includes a mounting portion 10 and three cleaning members 20, and the three cleaning members 20 are evenly arranged along the circumference of the mounting portion 10. Of course, in other embodiments, the number of the cleaning members 20 may be one or more, and the multiple cleaning members 20 may be evenly arranged or unevenly arranged, that is, eccentrically arranged.

[0029] The present invention does not limit this.

[0030] Optionally, the mounting portion 10 is in an arc shape. Of course, in other embodiments, the mounting portion 10 may also be in other shapes, such as a quadrilateral, etc., which is not limited by the present invention. The mounting portion 10 has a central axis 11 extending in a vertical direction, and the central axis 11 is also the rotation centerline of the cleaning member 20. The mounting portion 10 can be connected to the main body of the cleaning device to mount the side sweep assembly 100 on the main body of the cleaning device.

[0031] Each of the cleaning members 20 includes a brush arm 21 and bristles 22, and the brush arm 21 is connected to the mounting portion 10 and the bristles 22, respectively. Optionally, the mounting portion 10 and the brush arm 21 may be made of the same material. Preferably, the mounting portion 10 and the brush arm 21 may be integrally formed to reduce the process and reduce the cost. Of course, in other embodiments, the mounting portion 10 and the brush arm 21 may also be made of different materials, which is not limited by the present invention.

[0032] In this embodiment, the bristles 22 are in clusters and are implanted in the brush arm 21 so as to be fixedly connected to the brush arm 21 and connected to the mounting portion 10 via the brush arm 21 .

[0033] The brush arm 21 includes a first end 211 and a second end 212, wherein the first end 211 is used to connect with the mounting portion 10, and the second end 212 is used to connect with the bristles 22. In this embodiment, the distance between the brush arm 21 and the central axis 11 can gradually increase from the first end 211 to the second end 212. That is, the brush arm 21 can extend radially outward along the mounting portion 10 in a claw shape. Optionally, the end of the second end is made of soft material, so that even if it hits the surface or wall to be cleaned, it will damage the surface or wall to be cleaned.

[0034] Optionally, in this embodiment, the bristles 22 are disposed at the end of the second end 212 . In other embodiments, the bristles 22 may be disposed on the side of the second end 212 , which is not limited in the present invention.

[0035] The bristles 22 include a connection end 221 close to the brush arm and a cleaning end 222 away from the brush arm. That is, the cleaning end 222 is closer to the surface 200 to be cleaned relative to the connection end 221, and the cleaning end 222 is lower than the connection end 221, and the surface 200 to be cleaned can be cleaned by the cleaning end 222.

[0036] The side sweeping assembly 100 has a first working position, in which the distance between the cleaning end 222 and the central axis 11 is smaller than the distance between the connecting end 221 and the central axis 11. That is, the rotation radius of the cleaning end 222 close to the surface to be cleaned around the central axis 11 is smaller than the rotation radius of the connecting end 221 around the central axis 11. With such a configuration, the bristles 22 are in an inverted cone structure, so that the rotation diameter of the bristles 22 can present a structure of being smaller at the bottom and larger at the top, so that the winding radius of the hair on the bristles 22 is getting larger and larger, thereby preventing the hair from climbing up along the bristles 22 and winding, thereby improving the user experience.

[0037] Optionally, the length of the bristles 22 is greater than the length of the brush arm 21 , so that the height of the bristles 22 in the vertical direction can be changed by squeezing the bristles 22 , thereby achieving a change in the rotational diameter of the cleaning end 222 .

[0038] Optionally, the side sweeping assembly 100 also has a second working position. In the vertical direction, the height of the second working position is less than the height of the first working position. In other words, the side sweeping assembly 100 moves downward from the first working position to the second working position.

[0039] At the second working position, the distance between the cleaning end 222 and the central axis 11 is greater than the distance between the connecting end 221 and the central axis 11. That is, when the side sweeping assembly 100 is lowered to the second working position, the bristles 22 are pressed downward, so that the cleaning end 222 can be squeezed beyond the coverage range of the connecting end 221, that is, at this time, the cleaning end 222 has the maximum rotation diameter, so that the side sweeping assembly 100 can clean along the edge or along the wall.

[0040] Optionally, in the second working position, the cleaning end 222 is squeezed so as to extend to the side opposite thereto, and the coverage range of the connecting end 221 is extended from the opposite side. That is, at this time, the bristles 22 can present a shape similar to a "vertical fold", and the vertical of the "vertical fold" is similar to the shape of a parenthesis. When cleaning along the wall, the hair can be collected at the bend of the "vertical fold" of the bristles 22 and cannot continue to climb upwards. In addition, since the upper part of the "vertical fold" is still in a shape similar to a parenthesis, that is, the upper half is still a rotation diameter with a larger upper part and a smaller lower part, the hair can also be prevented from continuing to climb.

[0041] Optionally, in this embodiment, the orthographic projection of the bristles 22 on the surface to be cleaned 200 is arc-shaped and the arc is arranged around the mounting portion 10. In this way, the bristles 22 are spread out in an arc shape, and when it is in the second working position, it can ensure that the bristles 22 can clean along the edge or along the wall without affecting the cleaning efficiency.

[0042] Furthermore, the cleaning end 222 extends in a direction close to the central axis 11 and has a first extension axis 223, and the angle α between the first extension axis 223 and the surface to be cleaned 200 is an acute angle. When the bristles 22 rotate, since the angle α between the first extension axis 223 of the cleaning end 222 and the surface to be cleaned 200 is an acute angle, when there is hair on the surface to be cleaned 200, the hair will be pressed down by the inclined bristles 22 instead of being rubbed up by the bristles 22, thereby effectively preventing the hair from being entangled with the bristles 22.

[0043] Optionally, if there are still a few hairs caught in the bristles 22, since the angle α between the cleaning end 222 of the bristles 22 and the surface 200 to be cleaned is acute, and the bristles 22 present an inverted cone structure with a larger top and a smaller bottom, the hair will fall off downward along the bristles 22 instead of climbing upward, thereby preventing the hair from being entangled in the bristles 22 and affecting the cleaning effect.

[0044] Optionally, the side sweep assembly 100 can rotate circumferentially along the central axis 11, and has a rotation direction, and the bristles 22 are inclined in a direction away from the brush arm 21, and have an inclined direction, and the rotation direction is opposite to the inclined direction. For example, when the rotation direction of the side sweep assembly is counterclockwise, the bristles 22 are inclined in the clockwise direction of the brush arm 21. Conversely, when the rotation direction of the side sweep assembly is clockwise, the bristles 22 are inclined in the counterclockwise direction of the brush arm 21. By setting the inclination direction of the bristles 22 opposite to the rotation direction of the side sweep assembly 100, the rotation of the bristles 22 lags behind the brush arm 21, that is, the bristles 22 are pulled to rotate by the brush arm 21, so that the cleaning end 222 and the surface to be cleaned 200 present a more acute angle, thereby preventing hair from being entangled on the bristles 22.

[0045] Furthermore, the orthographic projections of the brush arm 21 and the bristles 22 on the horizontal plane do not overlap. That is, the bristles 22 do not continue to extend along the extension direction of the brush arm 21, but are arranged at an angle to the extension direction of the brush arm 21. That is, the bristles 22 are inclined in a direction away from the brush arm 21, so that the bristles 22 are spread out in an arc shape and lag behind the brush arm 21 in rotation, thereby having a larger cleaning range to improve the cleaning efficiency and avoid hair entanglement.

[0046] Furthermore, the angle between the second end 212 of the brush arm 21 and the bristles 22 is an obtuse angle β. The setting of the obtuse angle β can prevent the hair from easily bypassing the bristles 22 and winding around the brush arm 21, giving consumers a better experience and lower production, manufacturing and assembly costs.

[0047] Embodiment 2

[0048] See also Figures 4 to 6 As shown, the side sweeping assembly 100 of the second embodiment of the utility model is shown. The setting method of the mounting part 10 and the cleaning member 20 in the side sweeping assembly 100 is roughly the same, and the connection and positional relationship between the bristles 22 and the brush arm 21 are also similar, that is, in this embodiment, the bristles 22 are still arranged relatively offset from the brush arm 21, and when the bristles 22 rotate at the first working position, the rotation diameter thereof still tends to be smaller at the bottom and larger at the top, so that when the hair encounters the bristles 22, the rotation diameter of the bristles 22 gradually increases from the cleaning end 222 to the connecting end 221, so that the hair cannot continue to climb upward, so that the bristles 22 can block the hair and prevent it from climbing upward and winding around the side sweeping assembly 100. The difference is that in this embodiment, the brush arm 21 has an arc portion 213 arranged between the first end 211 and the second end 212, and the arc portion 213 is formed to be concave in the direction away from the central axis 11, so that the arc portion 213 has the largest rotation diameter compared with the first end 211 and the second end 212. With this arrangement, even if there is too much hair on the surface to be cleaned, and the hair passes over the bristles 22 and entangles on the brush arm 21, the presence of the arc portion 213 can prevent the hair from continuing to climb upward over the arc portion 213, thereby improving the anti-entanglement effect. The following description only describes the differences, and does not repeat the similarities.

[0049] Specifically, in this embodiment, the brush arm 21 has an arc portion 213 disposed between the first end 211 and the second end 212, and the brush arm 21 is bent in a direction away from the central axis 11 to form the arc portion 213. Moreover, the distance between the arc portion 213 and the central axis 11 is greater than the distance between the first end 211 / the second end 212 and the central axis 11. In this way, a structure is formed on the brush arm 21 in which the diameter of the arc portion 213 in the middle is large, and the diameters of the first end 211 at the top and the second end 212 at the bottom are small, that is, the brush arm 21 is generally in a shape similar to a parenthesis as a whole. Since the distance between the arc portion 213 and the central axis 11 is greater than the distance between the second end 212 and the central axis 11, the diameter increases from the second end 212 to the arc portion 213. Even if the hair is entangled to the second end 212, it will become tighter and tighter on the brush arm 21 when climbing upward and cannot continue to climb upward, that is, it cannot cross the arc portion 213 and continue to climb to the first end 211, thereby restricting the hair entanglement process and preventing the hair from being entangled to the mounting portion of the side sweeping assembly 100, thereby avoiding affecting the operation of the rotating motor.

[0050] Optionally, in the first working position of the side sweeping assembly 100 in this embodiment, the distance between the cleaning end 222 and the central axis 11 is smaller than the distance between the connecting end 221 and the central axis 11. In this way, the bristles 22 are in an inverted cone structure, so that the rotation diameter of the bristles 22 can present a structure that is smaller at the bottom and larger at the top, thereby preventing hair from climbing up along the bristles 22 and entangled, thereby improving the user experience.

[0051] However, the side sweeping assembly 100 also has a second working position. In the vertical direction, the height of the second working position is less than the height of the first working position. In other words, the side sweeping assembly 100 moves downward, from the first working position to the second working position.

[0052] At the second working position, the distance between the cleaning end 222 and the central axis 11 is greater than the distance between the connecting end 221 and the central axis 11. That is, when the side sweeping assembly 100 is lowered to the second working position, the bristles 22 are pressed downward, so that the cleaning end 222 can be squeezed beyond the coverage range of the connecting end 221, that is, at this time, the cleaning end 222 has the maximum rotation diameter, so that the side sweeping assembly 100 can clean along the edge or along the wall.

[0053] Embodiment 3

[0054] In the third embodiment, the structure and connection mode of the side sweeping assembly 100 are similar to those of the first embodiment, except that the bristles 22 and the brush arms 21 are rotatably connected in the third embodiment. The following description only describes the differences, and the similarities are not repeated.

[0055] In this embodiment, the bristles 22 are rotatably connected to the end or side wall of the second end 212 of the brush arm 21 .

[0056] Optionally, the bristles 22 are rotatably connected to the brush arm 21 through a rotating shaft. Of course, the bristles 22 can also be rotatably connected to the brush arm 21 through other methods, which is not limited in the present invention.

[0057] Optionally, the brush arm 21 has at least one limiting portion, which limits the angle of the bristles 22 relative to the brush arm 21, thereby preventing the bristles 22 from rotating with the brush arm 21. Preferably, the limiting portion makes the angle between the bristles 22 and the extension axis of the second end 212 of the brush arm 21 an acute angle.

[0058] Furthermore, when the cleaning member 20 rotates along the central axis 00 following the mounting portion 10, since the bristles 22 are rotationally connected to the brush arm 21 and the rotation angle is limited by the limiting portion, the brush arm 21 rotates before the bristles 22, so that the bristles 22 have a motion lag relative to the brush arm 21, so that there is an acute angle between the bristles 22 and the surface to be cleaned. Therefore, when there is hair on the surface to be cleaned 200, the hair will be pressed down by the inclined bristles 22 instead of being rubbed up by the bristles 22, thereby effectively preventing the hair from being entangled on the bristles 22.

[0059] Optionally, the brush arm 21 has two limit parts, which are respectively located on the left and right sides of the extension axis of the second end 212. When the brush arm 21 rotates clockwise, the bristles 22 can be blocked by the limit part on the right side, so that the movement of the bristles 22 is later than that of the brush arm 21, so that there is an acute angle between the bristles 22 and the surface to be cleaned. When the brush arm 21 rotates counterclockwise, the bristles 22 can be blocked by the limit part on the left side, so that the movement of the bristles 22 is later than that of the brush arm 21, so that there is an acute angle between the bristles 22 and the surface to be cleaned.

[0060] Optionally, in this embodiment, when the side sweep assembly 100 is in the first working position, the distance between the cleaning end 222 and the central axis 11 is smaller than the distance between the connecting end 221 and the central axis 11, that is, the bristles 22 are in an inverted cone structure, so that the rotation diameter of the bristles 22 can present a structure that is small at the bottom and large at the top. In other embodiments, the distance between the cleaning end 222 of the bristles 22 and the central axis 11 can also be greater than the distance between the connecting end 221 and the central axis 11. That is, the bristles 22 do not necessarily have to be in an inverted cone structure. The present utility model is not limited to this.

[0061] Embodiment 4

[0062] In the fourth embodiment, the structure and connection mode of the side sweeping assembly 100 are similar to those of the third embodiment, except that in the fourth embodiment, the bristles 22 and the brush arm 21 can be fixedly connected or rotatably connected. For the sake of clarity, the following description only describes the fixed connection between the bristles 22 and the brush arm 21, and the rotatable connection can refer to the content of the third embodiment.

[0063] In this embodiment, the bristles 22 are fixedly connected to the brush arm 21, but the bristles 22 are made of soft material. In addition, the length of the bristles 22 is greater than the length of the brush arm 21. When the bristles 22 rotate along the central axis 11 with the brush arm 21, the connecting end 221 rotates before the cleaning end 222. That is, the cleaning end 222 has a motion hysteresis relative to the connecting end 221, so that there is an acute angle between the cleaning end 222 and the surface to be cleaned. Therefore, when there is hair on the surface to be cleaned 200, the hair will be pressed down by the inclined cleaning end 222, and will not be rubbed up by the cleaning end 222, thereby effectively preventing the hair from being entangled with the bristles 22.

[0064] Embodiment 5

[0065] The present embodiment provides a cleaning device, which includes a main body and a side sweeping assembly 100, wherein the side sweeping assembly 100 is arranged below the main body, and the side sweeping assembly 100 can be rotated for cleaning. The cleaning device can be a cleaning robot or a base station, and the side sweeping assembly 100 can clean a surface 200 (e.g., the ground) to be cleaned when installed in the cleaning robot, and can clean the inside of the base station when the side sweeping assembly 100 is installed in the base station. Of course, the scene and location of the installation of the side sweeping assembly 100 are not limited, and can be specifically set as needed.

[0066] Further, the cleaning device may include two sets of side sweeping assemblies 100 located at both ends of the main body, and the bristles 22 in the two sets of side sweeping assemblies 100 may have opposite inclination directions away from the brush arm 21. For example, the side sweeping assembly 100 disposed on the left side of the main body rotates clockwise, while the bristles 22 deviate from the brush arm 21 in a counterclockwise direction. The side sweeping assembly 100 disposed on the right side of the main body rotates counterclockwise, while the bristles 22 deviate from the brush arm 21 in a clockwise direction.

[0067] In summary, the bristles 22 in the side sweeping assembly 100 of the present invention may include a connecting end 221 close to the brush arm and a cleaning end 222 away from the brush arm, and the distance between the cleaning end 222 and the central axis 11 is smaller than the distance between the connecting end 221 and the central axis 11. By arranging the cleaning end 222 closer to the central axis 11 than the connecting end 221, the rotation diameter of the bristles 22 around the central axis 11 presents a structure of being smaller at the bottom and larger at the top, thereby preventing the hair from climbing up along the bristles 22 and being entangled, thereby improving the user experience.

[0068] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model.
