[0052] In order to make the technical solutions and advantages of the present application more clear, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.
[0053] Cleaning equipment such as sweeping robots are common household appliances that can automatically clean the floor in the room, bringing great convenience to people's lives.
[0054] In order to improve the cleaning effect of corners and other corners, most cleaning devices on the market are currently equipped with side brushes. One of the motors of the cleaning device drives the side brush to rotate to clean the corners, and the other motor drives the side brush to swing outward relative to the main body of the cleaning device, thereby increasing the cleaning range of the side brush and allowing the side brush to better reach the dead corner. However, this design results in a more complex structure of the transmission component and a large number of motors, which not only increases the production cost of the cleaning device, but also increases the overall volume and weight of the cleaning device.
[0055] In order to solve the above technical problems, an embodiment of the present application provides a cleaning component 1 and a cleaning device.
[0056] like Figure 1 and Figure 2 As shown, the cleaning assembly 1 includes a driving member 11, a gear transmission assembly 12 and a side brush body 13. The gear transmission assembly 12 is respectively connected to the driving member 11 and the side brush body 13. The driving member 11 is used to drive the side brush body 13 to rotate through the gear transmission assembly 12, and is also used to drive the side brush body 13 to swing.
[0057] The cleaning assembly 1 is applied to a cleaning device, which includes a main body. For example, the cleaning device is a sweeping robot, and when the cleaning device is working, the driving member 11 drives the side brush body 13 to rotate around a rotating shaft perpendicular to the ground, and can also drive the side brush body 13 to at least partially extend out of the coverage surface of the main body, thereby improving the cleaning effect of the side brush body 13.
[0058] In this embodiment, the cleaning assembly 1 adopts gear transmission to transmit power, which has the advantages of high efficiency, compact structure, high reliability, etc. The gear transmission assembly 12 has two transmission routes, one of which is used to use the power of the driving member 11 to drive the side brush body 13 to rotate around the vertical rotation axis, and the other is used to use the power of the driving member 11 to drive the side brush body 13 to swing outward or retract relative to the main body.
[0059] It can be understood that, driven by the driving member 11, the cleaning component 1 can swing outward or retract inward relative to the main body as a whole, or only the gear transmission component 12 and the side brush body 13 can swing outward or retract inward relative to the main body, or only the side brush body 13 can swing outward or retract inward relative to the main body.
[0060] For example, Figure 1 The schematic diagram shows the state of the cleaning component 1 as a whole being retracted relative to the main body. Figure 2 The schematic diagram shows the state of the cleaning component 1 when it is swung outward relative to the main body. Figure 1 and Figure 2 As shown, the cleaning device also includes a fixing mechanism 2, which is fixedly connected to the main body. The driving member 11 is located outside the shell 121. Driven by the driving member 11, the cleaning component 1 can swing outward or retract as a whole relative to the fixing mechanism 2 and the main body.
[0061] The cleaning component 1 provided in the embodiment of the present application is respectively connected to the driving member 11 and the side brush body 13 through the gear transmission assembly 12. On the one hand, the driving member 11 can transmit power to the side brush body 13 through the gear transmission assembly 12, so that the side brush body 13 rotates, thereby improving the cleaning effect on the ground; on the other hand, the driving member 11 can drive the side brush body 13 to swing, so that the side brush body 13 is swung outward or retracted relative to the main body of the cleaning device, thereby increasing the movable range of the side brush body 13, allowing the side brush body 13 to penetrate into the blind spot area, thereby improving the cleaning effect on the blind spot area; using the same driving member 11 to realize the rotation and outward swing drive of the side brush body 13, there is no need to set up multiple motors, thereby reducing the number of motors of the cleaning component 1, which is beneficial to reducing the production cost, volume and weight of the cleaning component 1.
[0062] In a specific embodiment, Figures 3 to 6 As shown, the gear transmission assembly 12 includes a first transmission gear set 123 and a second transmission gear set 124, and the first transmission gear set 123 and the second transmission gear set 124 are both transmission-connected to the driving member 11. The first transmission gear set 123 is used to transmit the power of the driving member 11, so that the side brush body 13 rotates, and the second transmission gear set 124 is used to transmit the power of the driving member 11, so that the side brush body 13 swings.
[0063] By providing the first transmission gear set 123 and the second transmission gear set 124, the side brush body 13 can not only rotate to clean the floor, but also swing outward relative to the main body of the cleaning device, so that the side brush body 13 can penetrate into the blind spot area to clean the blind spot.
[0064] Furthermore, the first transmission gear set 123 includes a first driving gear 1232, a first gear 1233, a second gear 1234 and a side brush gear 1235. The side brush gear 1235 is coaxially connected to the side brush body 13 and rotates synchronously. The first gear 1233 and the second gear 1234 are respectively connected to the side brush gear 1235. The first driving gear 1232 is connected to the driving member 11. The first driving gear 1232, the first gear 1233 and the second gear 1234 are coaxially arranged. The first driving gear 1232 can move in the axial direction, so as to be connected to the first gear 1233 or the second gear 1234 and rotate synchronously.
[0065] For example, Figure 5 As shown, the first gear 1233 and the second gear 1234 are respectively located on both sides of the first driving gear 1232 in the thickness direction, the first gear 1233, the second gear 1234 and the first driving gear 1232 are installed on the same mounting shaft, the first gear 1233 and the second gear 1234 can both rotate around the mounting shaft, and the first driving gear 1232 can not only rotate around the mounting shaft, but also move along the length direction of the mounting shaft.
[0066] The driving member 11 is a rotary driving device, and its output shaft can rotate around its own central axis, and the first driving gear 1232 can move axially with the rotation of the output shaft of the driving member 11. For example, when the output shaft of the driving member 11 rotates forward, the first driving gear 1232 moves axially to connect with the first gear 1233 and rotate synchronously; when the output shaft of the driving member 11 rotates reversely, the first driving gear 1232 moves axially to connect with the second gear 1234 and rotate synchronously. Through this arrangement, no matter whether the output shaft of the driving member 11 rotates forward or reversely, the power of the driving member 11 can be transmitted to the side brush gear 1235, so that the side brush gear 1235 rotates.
[0067] Furthermore, the first transmission gear set 123 also includes a second driving gear 1231 meshing with the first driving gear 1232, the second driving gear 1231 is connected to the driving member 11, the first driving gear 1232 and the second driving gear 1231 are both cylindrical bevel gears, and the thickness of the first driving gear 1232 is less than the thickness of the second driving gear 1231.
[0068] Specifically, the gear transmission assembly 12 further includes a driving gear set 122. Figure 6As shown, the drive gear set 122 includes an output gear 1221, a first-stage reduction gear 1222, and a second-stage reduction gear 1223. The output gear 1221 is coaxially connected to the output shaft of the driving member 11. The first-stage reduction gear 1222 meshes with the output gear 1221 and the second-stage reduction gear 1223 respectively. The second-stage reduction gear 1223 is coaxially connected to and rotates synchronously with the second drive gear 1231. The power of the driving member 11 is transmitted to the second drive gear 1231 through the output gear 1221, the first-stage reduction gear 1222, and the second-stage reduction gear 1223 in sequence, causing the second drive gear 1231 to rotate. Exemplarily, as Figure 6 shown, there are two first-stage reduction gears 1222. The two first-stage reduction gears 1222 are arranged axially. One of the first-stage reduction gears 1222 meshes with the output gear 1221, and the other first-stage reduction gear 1222 meshes with the second-stage reduction gear 1223, ensuring the stability and smoothness of the transmission and avoiding jamming.
[0069] As Figure 5 shown, both the second drive gear 1231 and the first drive gear 1232 are cylindrical helical gears, and the thickness of the first drive gear 1232 is less than the thickness of the second drive gear 1231. During the forward or reverse rotation of the output shaft of the driving member 11, the axial component force generated by the meshing of the second drive gear 1231 and the first drive gear 1232 can realize the axial movement of the first drive gear 1232.
[0070] Furthermore, clamping members 1232a are respectively arranged on both sides of the first drive gear 1232 in the thickness direction. During the meshing rotation of the second drive gear 1231 and the first drive gear 1232, the first drive gear 1232 can move axially, so as to be connected to the first gear 1233 or the second gear 1234 through the clamping members 1232a, and further realize the synchronous rotation of the first drive gear 1232 and the first gear 1233 or the second gear 1234.
[0071] Clamping members 1232a are convexly provided on both surfaces of the first drive gear 1232 in the thickness direction. By providing 1232a, when the first drive gear 1232 moves upward, the clamping member 1232a on the first drive gear 1232 cooperates with the second gear 1234 for connection, and the first drive gear 1232 and the second gear 1234 rotate synchronously; when the first drive gear 1232 moves downward, the clamping member 1232a on the first drive gear 1232 cooperates with the first gear 1233 for connection, and the first drive gear 1232 and the first gear 1233 rotate synchronously. Exemplarily, as Figure 5 shown, the clamping member 1232a is a pawl.
[0072] Furthermore, the number of gear transmission stages between the first gear 1233 and the side brush gear 1235 is n stages, and the number of gear transmission stages between the second gear 1234 and the side brush gear 1235 is n + 1 stages, where n is a positive integer.
[0073] Both the first gear 1233 and the second gear 1234 can transmit power to the side brush gear 1235. Since the number of gear transmission stages between the second gear 1234 and the side brush gear 1235 is one more than that between the first gear 1233 and the side brush gear 1235, therefore, regardless of whether the output shaft of the driving member 11 rotates forward or backward, the rotation directions of the side brush gear 1235 and the side brush body 13 remain unchanged. Thus, the side brush body 13 pushes the garbage in a constant direction, facilitating the main body to collect the garbage, and at the same time increasing the service life of the side brush gear 1235.
[0074] Further, the first gear 1233 meshes with the side brush gear 1235. The first transmission gear set 123 further includes a third gear 1236 and a fourth gear 1237 that are coaxially connected and rotate synchronously. The third gear 1236 meshes with the second gear 1234, and the fourth gear 1237 meshes with the side brush gear 1235.
[0075] After the engaging member 1232a on the first driving gear 1232 is cooperatively connected with the first gear 1233, the first driving gear 1232 transmits power to the first gear 1233, thereby driving the side brush gear 1235 to rotate through the first gear 1233; after the engaging member 1232a on the first driving gear 1232 is cooperatively connected with the second gear 1234, the first driving gear 1232 transmits power to the second gear 1234, and the second gear 1234 further transmits the power to the third gear 1236. The fourth gear 1237 moves along with the third gear 1236 and drives the side brush gear 1235 to rotate. At the same time, the side brush gear 1235 drives the first gear 1233 to rotate, causing the first gear 1233 to rotate idly passively, avoiding the phenomenon of jamming.
[0076] In this embodiment, the number of gear transmission stages between the first gear 1233 and the side brush gear 1235 is one stage, and the number of gear transmission stages between the second gear 1234 and the side brush gear 1235 is two stages, which can ensure that regardless of whether the output shaft of the driving member 11 rotates forward or backward, the rotation directions of the side brush gear 1235 and the side brush body 13 remain unchanged. Thus, the side brush body 13 pushes the garbage in a constant direction, facilitating the main body to collect the garbage, and at the same time increasing the service life of the side brush gear 1235.
[0077] The cleaning assembly 1 further includes a housing 121 and a fixed gear 14. The gear transmission assembly 12 and the fixed gear 14 are both located inside the housing 121, and the fixed gear 14 is used for fixedly connecting with the main body. The second transmission gear set 124 is in transmission connection with the fixed gear 14, and the second transmission gear set 124 can move circumferentially along the fixed gear 14 under the drive of the driving member 11, thereby driving the edge brush body 13 to swing relative to the fixed gear 14.
[0078] Specifically, as Figure 3 and Figure 4 shown, the second transmission gear set 124 is respectively in transmission connection with the fixed gear 14 and the second driving gear 1231.
[0079] As Figure 4 shown, the fixed gear 14 is generally fan-shaped. The fixed gear 14 is installed in the fixing mechanism 2, so as to realize the fixed relative position between the fixed gear 14 and the main body, and the fixed gear 14 and the main body remain relatively stationary.
[0080] The second transmission gear set 124 is used to realize the outward swing or inward retraction of the edge brush body 13. Exemplarily, during the relative movement generated by the meshing of the second transmission gear set 124 and the fixed gear 14, the gear transmission assembly 12, the driving member 11 and the edge brush body 13 as a whole all swing circumferentially along the fixed gear 14, thereby realizing the outward swing or inward retraction of the edge brush body 13.
[0081] Further, as Figure 3 and Figure 4 shown, the second transmission gear set 124 includes a fifth gear 1241 and a sixth gear 1242. The fifth gear 1241 is in transmission connection with the driving member 11. For example, the fifth gear 1241 is in transmission connection with the driving member 11 by meshing with the second driving gear 1231. The sixth gear 1242 meshes with the fixed gear 14, and the fifth gear 1241 can be separated from or meshed with the sixth gear 1242. Exemplarily, the separation or meshing between the fifth gear 1241 and the sixth gear 1242 can be realized by components such as a fork and a push rod.
[0082] In this embodiment, the driving member 11 transmits power to the fifth gear 1241. When the fifth gear 1241 meshes with the sixth gear 1242, the fifth gear 1241 transmits power to the sixth gear 1242. The sixth gear 1242 rolls along the tooth surface of the fixed gear 14 by meshing with the fixed gear 14, thereby driving the entire gear transmission assembly 12 and the side brush body 13 to swing outward or inward relative to the main body; when the fifth gear 1241 is separated from the sixth gear 1242, the fifth gear 1241 no longer transmits power to the sixth gear 1242. At this time, the sixth gear 1242 and the fixed gear 14 remain relatively stationary, and the entire gear transmission assembly 12 and the side brush body 13 no longer swing outward or inward relative to the main body.
[0083] In a specific embodiment, as Figure 7 shown, the fifth gear 1241 includes a first sub-gear 1241a, a second sub-gear 1241b, and a planetary gear 1241c. The first sub-gear 1241a is in transmission connection with the driving member 11. For example, the first sub-gear 1241a is in transmission connection with the driving member 11 through meshing with the second driving gear 1231. The first sub-gear 1241a and the second sub-gear 1241b are coaxially connected and rotate synchronously. The radial dimension of the second sub-gear 1241b is smaller than the radial dimension of the first sub-gear 1241a. The planetary gear 1241c meshes with the second sub-gear 1241b, and the planetary gear 1241c can move circumferentially along the second sub-gear 1241b, so as to be separated from or mesh with the sixth gear 1242.
[0084] As Figure 7 shown, the first sub-gear 1241a and the second sub-gear 1241b are coaxially arranged. The pitch circle diameter of the first sub-gear 1241a is larger than the pitch circle diameter of the second sub-gear 1241b. The planetary gear 1241c is located outside the second sub-gear 1241b and meshes with the second sub-gear 1241b. Exemplarily, the planetary gear 1241c is slidably connected to the surface of the first sub-gear 1241a.
[0085] During the rotation of the second sub-gear 1241b, the planetary gear 1241c can move around the second sub-gear 1241b. For example, when the second sub-gear 1241b rotates clockwise, the planetary gear 1241c moves clockwise outside the second sub-gear 1241b; when the second sub-gear 1241b rotates counterclockwise, the planetary gear 1241c moves counterclockwise outside the second sub-gear 1241b.
[0086] The sixth gear 1242 is located on one side of the second sub-gear 1241b in the radial direction. When the planetary gear 1241c moves along a circular path outside the second sub-gear 1241b, the planetary gear 1241c can approach or move away from the sixth gear 1242, thereby achieving engagement or disengagement of the planetary gear 1241c and the sixth gear 1242.
[0087] Furthermore, if Figure 7 As shown, a slider mechanism 1243 is arranged on one side surface of the first sub-gear 1241a, and the slider mechanism 1243 includes a slide 1243a and a slider body 1243b located on the slide 1243a, the slide 1243a is annular and coaxially arranged on the outer side of the second sub-gear 1241b, the planetary gear 1241c is rotatably mounted on the slider body 1243b, and the slider body 1243b can rotate around the central axis of the first sub-gear 1241a.
[0088] like Figure 7 As shown, the slideway 1243a is located on the outer periphery of the second sub-gear 1241b, and the slideway 1243a is annular, the slider body 1243b is disposed on the slideway 1243a, and the planetary gear 1241c can rotate relative to the slider body 1243b.
[0089] Optionally, the slider body 1243b is fixedly connected to the slide 1243a, and the slide 1243a is rotatably connected to the first sub-gear 1241a, that is, the slide 1243a and the slider body 1243b can rotate together around the central axis of the first sub-gear 1241a; or, the slide 1243a is fixed to the surface of the first sub-gear 1241a, the slider body 1243b is slidably connected to the slide 1243a, and the slider body 1243b can rotate around the central axis of the first sub-gear 1241a relative to the slide 1243a.
[0090] Furthermore, if Figure 8 As shown, the sixth gear 1242 includes a third sub-gear 1242a, a fourth sub-gear 1242b and a shifting member 1242c which are coaxially connected. The third sub-gear 1242a and the fourth sub-gear 1242b rotate synchronously. The third sub-gear 1242a is used to engage with or disengage from the planetary gear 1241c. The fourth sub-gear 1242b is engaged with the fixed gear 14. The shifting member 1242c is used to shift the planetary gear 1241c, thereby disengaging the planetary gear 1241c from the third sub-gear 1242a.
[0091] When the third sub-gear 1242a is meshed with the planetary gear 1241c, as the output shaft of the driving member 11 rotates, the fourth sub-gear 1242b rolls along the tooth surface of the fixed gear 14 by meshing with the fixed gear 14, thereby driving the gear transmission assembly 12 as a whole and the side brush body 13 to swing outward or retract inward relative to the main body; when the third sub-gear 1242a is separated from the planetary gear 1241c, the fourth sub-gear 1242b no longer rotates, and the fourth sub-gear 1242b and the fixed gear 14 remain relatively stationary, and the gear transmission assembly 12 as a whole and the side brush body 13 cannot swing outward or retract inward relative to the main body.
[0092] When the side brush body 13 is swung outward or retracted into position, the shifting member 1242c shifts the planetary gear 1241c, so that the planetary gear 1241c is separated from the third sub-gear 1242a and stops transmission, thereby stopping the side brush body 13 from swinging outward or retracting.
[0093] like Figure 8 As shown, the toggle member 1242c is in a quasi-annular shape, and a convex angle is provided at one radial end of the toggle member 1242c. The convex angle extends along the radial direction of the toggle member 1242c, and the toggle member 1242c toggles the planetary gear 1241c via the convex angle.
[0094] Furthermore, if Figure 8 As shown, a protruding column 1242aa is disposed on one side surface of the third sub-gear 1242a close to the toggle member 1242c. The protruding column 1242aa can move along with the third sub-gear 1242a, thereby pushing the toggle member 1242c to rotate.
[0095] The boss 1242aa is protruding from the side surface of the third sub-gear 1242a away from the fourth sub-gear 1242b. When the third sub-gear 1242a rotates, the boss 1242aa rotates synchronously with the third sub-gear 1242a, and when it contacts the toggle member 1242c, it pushes the toggle member 1242c to rotate, so that the toggle member 1242c can toggle the planetary gear 1241c.
[0096] like Figure 8 As shown, the edge of the toggle member 1242c is provided with an escape groove 1242ca, and the protruding column 1242aa is located in the escape groove 1242ca. When the cam rotates clockwise along with the third sub-gear 1242a, the cam contacts the upper side wall of the escape groove 1242ca, thereby pushing the toggle member 1242c to rotate in the clockwise direction; when the cam rotates counterclockwise along with the third sub-gear 1242a, the cam contacts the lower side wall of the escape groove 1242ca, thereby pushing the toggle member 1242c to rotate in the counterclockwise direction.
[0097] The gear transmission assembly 12 further includes a telescopic rod 125 and an elastic member 126 disposed within the housing 121. One end of the telescopic rod 125 is rotatably disposed on the inner wall of the housing 121, and the other end of the telescopic rod 125 is rotatably disposed on a surface of the third secondary gear 1242a adjacent to the fourth secondary gear 1242b. The telescopic rod 125 is capable of telescoping along its own length direction. The elastic member 126 is disposed between the two ends of the telescopic rod 125, and the elastic member 126 is capable of elastically deforming along the length direction of the telescopic rod 125.
[0098] Specifically, cylinders are respectively protruded on the inner wall of the housing 121 and on the surface of the third secondary gear 1242a. The first end of the telescopic rod 125 is rotatably sleeved on the cylinder on the inner wall of the housing 121, and the second end of the telescopic rod 125 is rotatably sleeved on the cylinder on the surface of the third secondary gear 1242a. During the rotation of the sixth gear 1242, the second end of the telescopic rod 125 moves along with the third secondary gear 1242a, thereby generating a telescopic movement. As Figure 9 and Figure 10 shown, the fourth secondary gear 1242b is provided with a notch for avoiding the second end of the telescopic rod 125.
[0099] Both ends of the elastic member 126 are respectively connected to the first end and the second end of the telescopic rod 125. During the telescopic movement of the telescopic rod 125 along its own length direction, the elastic member 126 elastically deforms accordingly.
[0100] As Figure 9 shown, driven by the driving member 11, when the second driving gear 1231 rotates forward, the planetary gear 1241c is at position a and meshes with the third secondary gear 1242a, causing the third secondary gear 1242a to rotate. The fourth secondary gear 1242b rolls counterclockwise along the tooth surface of the fixed gear 14 driven by the third secondary gear 1242a, thereby driving the entire gear transmission assembly 12 and the side brush body 13 to swing outward relative to the main body. During this process, as the third secondary gear 1242a rotates, the second end of the telescopic rod 125 gradually moves from Figure 9 (a)'s position c to Figure 9 (b)'s position d, and then moves to Figure 9 (c)'s position e. During the process of the second end of the telescopic rod 125 moving from position c to position d, the elastic member 126 is in a state of being compressed to store force; when the second end of the telescopic rod 125 reaches Figure 9 (b)'s position d, the elastic member 126 is in a critical point state, and the pressure it receives reaches the maximum value. At this time, as long as the output shaft of the driving member 11 rotates slightly, the telescopic rod 125 will accelerate and rotate to Figure 9(c) At position e, the elastic member 126 releases the pressure, the telescopic rod 125 pushes the fourth sub-gear 1242b to rotate, and at the same time the boss 1242aa on the third sub-gear 1242a accelerates its rotation, driving the toggle member 1242c to rotate, pushing the planetary gear 1241c away, causing the planetary gear 1241c to move to position b, so that the planetary gear 1241c is separated from the third sub-gear 1242a. At this time, the third sub-gear 1242a no longer rotates, and the transmission between the fourth sub-gear 1242b and the fixed gear 14 stops. The side brush body 13 swings outward into place and rotates normally.
[0101] like Figure 10 As shown, driven by the driving member 11, when the second driving gear 1231 reverses, the planetary gear 1241c is in position f and meshes with the third sub-gear 1242a, causing the third sub-gear 1242a to rotate, and the fourth sub-gear 1242b rolls clockwise along the tooth surface of the fixed gear 14 driven by the third sub-gear 1242a, thereby driving the gear transmission assembly 12 as a whole and the side brush body 13 to retract relative to the main body. In this process, as the third sub-gear 1242a rotates, the second end of the telescopic rod 125 gradually moves from Figure 10 The position g in (d) moves to Figure 10 (e) h position, and then move to Figure 10 (f) i position. During the movement of the second end of the telescopic rod 125 from position g to position h, the elastic member 126 is in a compressed force storage state; Figure 10 (e) When the elastic member 126 is at the critical point, the pressure on it reaches the maximum value. At this time, as long as the output shaft of the driving member 11 rotates slightly, the telescopic rod 125 will accelerate to rotate to Figure 10 (f) At position i in the figure, the elastic member 126 releases the pressure, and the telescopic rod 125 pushes the fourth sub-gear 1242b to rotate. At the same time, the boss 1242aa on the third sub-gear 1242a rotates faster, driving the toggle member 1242c to rotate, pushing the planetary gear 1241c away, causing the planetary gear 1241c to move to position j, so that the planetary gear 1241c is separated from the third sub-gear 1242a. At this time, the third sub-gear 1242a no longer rotates, and the transmission between the fourth sub-gear 1242b and the fixed gear 14 stops. The side brush body 13 is received in place and rotates normally.
[0102] Understandably, Figure 9 and Figure 10 It is only used to describe the relative position changes between parts, and cannot represent the actual position changes between parts, nor can it represent the actual size of each part.
[0103] The present application also provides a cleaning device, which includes a main body and the cleaning assembly 1 provided in any of the above embodiments, and the cleaning assembly 1 is installed on the main body.
[0104] Exemplarily, the cleaning device is a floor sweeping robot. On the one hand, the driving member 11 can transmit power to the side brush body 13 through the gear transmission assembly 12, so as to make the side brush body 13 rotate, improving the cleaning effect on the ground; on the other hand, the driving member 11 can drive the side brush body 13 to swing, so that the side brush body 13 swings outwards or inwards relative to the main body, increasing the movement range of the side brush body 13, enabling the side brush body 13 to reach into dead corners, and improving the cleaning effect on dead corner areas; using the same driving member 11 to drive the rotation and outward swing of the side brush body 13 eliminates the need to set multiple motors, reducing the number of motors of the cleaning device, which is beneficial to reducing the production cost, volume and weight of the cleaning device.
