Description

Technical Field

[0001] The present application relates to the field of electrical equipment, and in particular to a cleaning device, a cleaning component and a working method of the cleaning device. Background Art

[0002] At present, with the development of technology, sweeping robots can autonomously clean the floor of the home. There are two main steps in the process of sweeping the floor: first, collect and process particles, dust and other garbage on the floor to clean the floor; second, mop the floor to clean the floor. When the cleaning robot is cleaning the floor, it not only needs the cleaning roller brush at the dust collection port to participate, but also needs the cleaning side brush to sweep the garbage far from the dust collection port to the suction range of the dust collection port, so as to facilitate collection into the cleaning robot.

[0003] However, the side brushes on existing sweeping robots either cannot effectively solve the problem of cleaning corners, or the structure of the side brushes is too complicated and prone to malfunction. Summary of the invention

[0004] In view of the above problems, the present application proposes a cleaning device, a cleaning component and a cleaning device working method to solve the above problems or at least partially solve the above problems.

[0005] In one embodiment of the present application, a cleaning device is provided, the cleaning device comprising:

[0006] Equipment body;

[0007] A cleaning assembly is arranged at the edge of the device body, the cleaning assembly comprises a driving device and a cleaning body, and the driving device can drive the cleaning body to rotate;

[0008] Among them, the driving device has at least two working modes. In the first working mode, the driving device outputs power to drive the cleaning body to rotate; in the second working mode, the driving device outputs reverse power to drive the cleaning body to swing outward to clean an area farther outside the side of the equipment body.

[0009] In another embodiment of the present application, a cleaning assembly is also provided, the cleaning assembly comprising: a housing;

[0012] The driving device has at least two working modes. In the first working mode, the driving device outputs power to drive the cleaning body to rotate; in the second working mode, the driving device outputs reverse power to drive the cleaning body to swing outward to clean an area farther outside the side of the device body.

[0013] In one embodiment of the present application, a cleaning device working method is also provided, which is applicable to the above-mentioned cleaning device, and the cleaning device working method includes:

[0014] The driving device works in a first working mode, and the driving device drives the cleaning body to rotate;

[0015] Based on the outward swing cleaning instruction, the driving device switches from the first working mode to the second working mode, and the driving device drives the cleaning component to swing outward;

[0016] After the cleaning assembly swings outward to a preset position, the driving device switches to the first working mode.

[0017] In the technical solution of the embodiment of the present application, the cleaning body on the cleaning assembly can not only rotate to sweep the garbage on the side of the cleaning device to the bottom of the device body; the cleaning body can also swing outward to sweep the area farther outside the side of the device body. The driving device can rotate or swing outward by simply changing the direction of the output power, which not only facilitates the rapid switching of the working state of the cleaning body, but also does not require the provision of other power devices to drive the cleaning body to swing outward.

[0032] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

The descriptions of "first", "second", etc. in this article are used to distinguish different directions, structures, components, etc., and do not represent the order of precedence. In addition, the embodiments described below are only part of the embodiments of this application, rather than all the embodiments.

[0034] Figure 1 A structural diagram of a cleaning device provided by an embodiment of the present application when the side brush is in a non-swinging state; Figure 2 A structural diagram of a cleaning device provided by an embodiment of the present application with its side brush swung outward; Figure 3 A three-dimensional structural diagram of a cleaning component provided in an embodiment of the present application. Figures 1 to 3 In one embodiment of the present application, a cleaning device is provided, which includes: a device body 1 and a cleaning component 2. The cleaning component 2 is arranged at the edge of the device body 1, and the cleaning component 2 includes a driving device 3 and a cleaning body 4. The driving device 3 can drive the cleaning body 4 to rotate, and is used to sweep the garbage on the side of the device body 1 to the bottom of the device body 1. The following is a detailed description of the cleaning component 2 as a side brush component and the cleaning body 4 as a side brush. The cleaning equipment includes but is not limited to: a sweeping robot, a sweeping and mopping robot, etc. Usually, a dust collection device and a dust collection port are provided on this type of cleaning equipment. The dust collection device can sweep and suck the garbage, dust and other dirt on the surface to be cleaned into the dust collection box through the dust collection port. However, since the dust collection port is provided at the bottom of the cleaning equipment, it cannot effectively sweep and collect the garbage on the side of the cleaning equipment, for example Figure 1 The dotted line A in the middle represents the approximate area of ​​the dust collection port. When the cleaning device is close to the foot of the wall, the garbage in the corner will be difficult to be sucked into the dust collection port. Therefore, it is necessary to set a cleaning component 2 on the cleaning device. The cleaning range of the cleaning component 2 is partly located at the bottom of the cleaning device, and the other part is located on the side of the cleaning device and extends to the corner of the wall, for example Figure 1 The circular area of ​​the dotted line B. As the cleaning body 4 rotates, the cleaning body 4 can sweep the garbage at the corner to the bottom of the cleaning device, which is conducive to the dust collection port to sweep and collect the garbage.

[0035] Furthermore, the driving device 3 has at least two working modes. In the first working mode, the driving device 3 outputs power to drive the cleaning body 4 to rotate; in the second working mode, the driving device 3 outputs reverse power to drive the cleaning body 4 to swing outward to clean a wider area outside the side of the device body 1. It can be understood that the driving device 3 switches the working mode by changing the direction of the output power. In the second working mode, the cleaning range of the cleaning body 4 is Figure 2 The circular area of ​​the middle dashed line C. Figure 1 After the cleaning body 4 is swung outward, the cleaning range of the cleaning body 4 is offset to the outside of the upper and oblique sides of the device body 1. Regarding the swinging direction of the cleaning body 4, the cleaning body 4 may be swung outward along the width direction of the device body 1 to the right side of the device body 1, or may be swung outward along the length direction of the device body 1 to the side of the front side of the device, or may be swung outward to the upper and oblique sides of the device body 1.

[0036] Furthermore, a receiving groove 21 is provided at the bottom of the equipment body 1. When the driving device 3 works in the first working mode, the cleaning body 4 is located in the receiving groove 21, and the power output by the driving device 3 drives the cleaning body 4 to rotate to achieve cleaning. When the driving device 3 works in the second working mode, the power output by the driving device 3 drives the cleaning body 4 to swing outward, and the cleaning body 4 exits the receiving groove 21 to clean an area farther outside the side of the equipment body 1. In a specific embodiment, the switching of the working mode of the driving device 3 can be achieved by changing the rotation direction of the power. For example, in the first working mode, the direction of the power output by the driving device 3 is clockwise, and in the second working mode, the direction of the power output by the driving device 3 is counterclockwise.

[0037] In the technical solution of the embodiment of the present application, the cleaning body 4 on the cleaning assembly 2 can not only rotate, but also swing outward to clean an area farther away from the side of the equipment body 1. The driving device 3 can rotate or swing outward by simply changing the direction of the output power, which not only facilitates the rapid switching of the working state of the cleaning body 4, but also does not require the provision of other power devices to drive the cleaning body 4 to swing outward. The driving device 3 has a relatively simple structure and occupies a small space.

[0038] Further, in one embodiment of the present application, when the driving device 3 is in the second working mode, the driving device 3 drives the cleaning body 4 to swing back and forth outward in a circular motion. Specifically, as the driving device 3 continues to output power, the cleaning body 4 swings back and forth outward in a circular motion, and the cleaning range of the cleaning body 4 is within Figure 1 The circular area of ​​the dashed line B and Figure 2The circular area of ​​the middle dotted line C changes back and forth in a cycle. This working mode can make the cleaning of the cleaning body 4 more efficient. In another embodiment of the present application, the driving device 3 drives the cleaning body 4 to swing outward to a preset position, such as the maximum swing limit position, and then locks it. Then the cleaning body 4 is always in the outward swing posture. After completing a specific cleaning task (such as the wall, the corner, the edge of an obstacle, etc.), the locking device is unlocked, and the cleaning body 4 is reset from the outward swing posture. The limit position of the outward swing of the cleaning body 4 can be set according to actual conditions, for example Figure 2 The cleaning body 4 can also be any position between the initial position and the extreme position. For example, the cleaning component 2 has multiple gears when it is swung outward, and different gears correspond to different positions between the initial position and the extreme position. The cleaning component 2 can be switched to different swing-out gears according to different situations.

[0039] Further, see Figures 3 to 6 , the driving device 3 includes a motor 5 and a transmission assembly 6. When the driving device 3 is in the first working mode, the rotational power output by the motor 5 is opposite in direction to the rotational power output by the driving device 3 in the second working mode. The motor 5 can switch the driving device 3 between the first working mode and the second working mode by changing the rotation direction.

[0040] The transmission assembly 6 is connected to the motor 5 and the cleaning body 4, respectively, and is used to transmit the rotational power output by the motor 5 to the cleaning body 4. Specifically, the motor 5 is connected to the input end of the transmission assembly 6, and the cleaning body 4 is detachably connected to the output end of the transmission assembly 6. In addition to transmitting the rotational power output by the motor 5, the transmission assembly 6 can also be used to reduce speed and control the rotation speed of the cleaning body 4 within a reasonable range to achieve a better cleaning effect.

[0041] In one embodiment provided in the present application, the transmission assembly 6 has at least two transmission paths, and when the motor 5 outputs rotational power in different directions, the transmission assembly 6 transmits the rotational power to the cleaning body 4 through different transmission paths. Specifically, different transmission paths can be used for the cleaning body 4 to achieve different functions or enter different working modes. For example, in the first working mode, the transmission assembly 6 drives the cleaning body 4 to rotate through the first transmission path, and in the second working mode, the transmission assembly 6 drives the cleaning assembly 2 to swing through the second transmission path. In addition, in the second working mode, the transmission assembly 6 can also simultaneously drive the cleaning body 4 to rotate and swing through the first transmission path and the second transmission path.

[0042] See also Figures 3 to 6, the transmission assembly 6 includes a plurality of gear sets, and the plurality of gear sets form two different transmission paths. Specifically, the first gear set includes a multi-stage reduction gear, which is mainly used to convert the higher speed of the motor 5 into a lower speed, thereby controlling the speed of the cleaning body 4 within a reasonable range. In the first working mode, the rotational power of the motor 5 is transmitted to the cleaning body 4 through the first transmission path. In a specific embodiment, the first gear set includes three sets of gears, and the three sets of gears form a three-stage reduction device. This application does not make specific restrictions on the number of gear sets in the first gear set, and it can be set according to actual conditions. In the technical solution provided in the present application, in addition to using multi-stage gears to achieve the function of speed reduction, the speed reduction of the cleaning body 4 can also be achieved by a worm gear device.

[0043] In addition, the second gear set includes a swing gear 8, which transmits another rotational power of the motor 5 to the cleaning body 4 through the second transmission path in the second working mode, and drives the cleaning body 4 to swing. The second gear set also includes two sets of reduction gears, which output a lower speed to the swing gear 8, and can effectively control the swing frequency of the cleaning body 4 within a reasonable range. In the technical solution of the present application, the transmission assembly 6 includes a plurality of gear sets. When the motor 5 outputs rotational power in different directions, the power can be transmitted to the cleaning body 4 through different gear sets to achieve switching of different working modes. The transmission assembly 6 has a simple structure, facilitates the rapid switching of the working state of the cleaning body 4, and occupies a small space, which is conducive to improving the integration of the equipment body 1.

[0044] In order to switch the working mode of the drive device 3, see Figures 4 to 6 In one embodiment provided in the present application, a first one-way bearing 9 is provided on one of the gears of the second gear set (e.g., the first gear 7 or the swing gear 8). When the drive device 3 is in the first working mode, the first one-way bearing 9 disconnects the second transmission path, and when the drive device 3 is in the second working mode, the first one-way bearing 9 connects the second transmission path. Specifically, when the drive device 3 is in the first working mode, the motor 5 rotates forward, at which time the first one-way bearing 9 is in a disconnected state, and the rotational power of the motor 5 cannot be transmitted to the cleaning body 4 through the second transmission path, and the cleaning body 4 does not swing. When the motor 5 is reversed, the rotation direction of all gears in the second gear set is also changed, and the first one-way bearing 9 is changed to a connected state, and the rotational power of the motor 5 can be transmitted to the cleaning body 4 through the second transmission path, and the cleaning body 4 swings outward.

[0045] See also Figure 8, the first one-way bearing 9 includes an inner ring 91, an outer ring 92 and a needle roller 93. The inner ring 91 and the outer ring 92 are respectively connected to different gears or rotating shafts. When the inner ring 91 rotates in the locking direction relative to the outer ring 92, the inner ring 91 and the outer ring 92 will rotate at the same time, which can be understood as the first one-way bearing 9 is turned into a connected state. When the inner ring 91 rotates in the opposite direction of the locking direction relative to the outer ring 92, the inner ring 91 and the outer ring 92 are separated from each other. At this time, the first one-way bearing 9 is equivalent to an ordinary rolling bearing.

[0046] See also Figures 5 to 8 In a specific embodiment, the transmission assembly 6 includes a first gear 7, the first gear 7 includes a main gear 71 and a sub-gear, the two sub-gears are respectively arranged on both sides of the main gear 71, wherein the second sub-gear 73 is connected to the main gear 71 through a first one-way bearing 9, and the first sub-gear 72 and the main gear 71 are an integral structure. When the main gear 71 rotates forward or reverse, the first sub-gear 72 will rotate with the main gear 71, while the second sub-gear 73 can only rotate in one direction with the main gear 71, and transmit the rotational power to the lower gear (swing gear 8).

[0047] Further, in an embodiment provided in the present application, the reverse power output by the driving device 3 can also drive the cleaning body 4 to rotate, and in the second working mode, the rotation direction of the cleaning body 4 is opposite to the rotation direction of the cleaning body 4 in the first working mode. Usually, when the transmission assembly 6 drives the cleaning body 4 to swing outward through the second transmission path, the second transmission path cannot simultaneously drive the cleaning body 4 to rotate. Therefore, in order to achieve the cleaning body 4 to rotate and clean while swinging outward, in the second working mode, the first transmission path of the transmission assembly 6 is not disconnected, and the rotational power output by the motor 5 can drive the cleaning body 4 to rotate through the first transmission path. In order to realize this technical solution, as described above, by setting the first sub-gear 72 and the main gear 71 into an integral structure, it can be achieved that when the motor 5 is in forward or reverse rotation, the first transmission path is always connected, thereby transmitting the forward rotational power and the reverse rotational power to the cleaning body 4 respectively.

[0048] In another embodiment provided in this application, see Figures 5 to 9, in the second working mode, the cleaning body 4 may not rotate. Specifically, in the second working mode, the transmission assembly 6 only outputs the rotational power of the motor 5 to the cleaning body 4 through the second transmission path to drive the cleaning body 4 to swing back and forth. In order to realize this technical solution, one of the gears of the first gear set (such as the first gear 7 or the lower gear) is provided with a second one-way bearing 10, and the locking directions of the first one-way bearing 9 and the second one-way bearing 10 are opposite. When the driving device 3 is in the first working mode, the second one-way bearing 10 is connected to the first transmission path, and when the driving device 3 is in the second working mode, the second one-way bearing 10 is disconnected from the first transmission path. In the technical solution of the present application, the cleaning body 4 does not rotate, and only swings back and forth, which can also achieve cleaning of the area outside the side of the equipment body 1.

[0049] In a specific implementation, the first one-way bearing 9 and the second one-way bearing 10 are respectively arranged between the main gear 71 of the first gear 7 and the first sub-gear 72 and the second sub-gear 73. When the main gear 71 rotates forward, the first one-way bearing 9 is locked and the second one-way bearing 10 is disconnected, and the rotational power of the motor 5 can drive the cleaning body 4 to rotate. When the main gear 71 rotates reversely, the first one-way bearing 9 is disconnected and the second one-way bearing 10 is locked, and the rotational power of the motor 5 can drive the cleaning body 4 to swing, and the cleaning body 4 does not rotate.

[0050] See also Figure 5 and Figure 6 In one embodiment provided in the present application, a driving member 11 is provided on the swing gear 8, and the driving member 11 can rotate together with the swing gear 8, and the driving member 11 is used to drive the cleaning body 4 to swing outward. The driving member 11 can be a cam or a connecting rod. Taking the cam as an example, the cam abuts against the swing arm 13, and when the cam rotates, the cam drives the swing arm 13 to swing, and the cleaning body 4 swings outward relative to the equipment body 1. Specifically, when the distal end of the cam abuts against the swing arm of the cleaning body 4, the cleaning body 4 swings outward to the extreme position; when the proximal end of the cam abuts against the swing arm of the cleaning body 4, the cleaning body 4 is reset to the receiving groove 21 on the equipment body 1.

[0051] In order to make the cleaning assembly 2 more compact and occupy less space, the driving device 3 includes a housing 12 and a swing arm 13. The motor 5 is arranged on the housing 12, one end of the swing arm 13 is rotatably connected to the housing 12, and the cleaning body 4 is arranged on the other end of the swing arm 13. When the swing arm 13 revolves around the housing 12, the cleaning body 4 will swing outward or reset. Figure 4 The direction of the middle arrow X is the swing direction of the swing arm 13. The swing arm 13 is a hollow structure, which includes a swing arm upper cover 131 and a swing arm lower cover 132, which are assembled to form a hollow swing arm 13, and some gears in the first gear set are arranged in the hollow structure.

[0052] Specifically, see Figure 5 , Figure 6 , Fig.11 and Fig.12 The first gear set includes a first gear 7, a second gear 16 and a third gear 17. The third gear 17 is arranged on the rotating shaft of the cleaning body 4, and the second gear 16 and the third gear 17 are located in the hollow structure of the swing arm 13. When the swing arm 13 swings, the second gear 16 and the third gear 17 will simultaneously revolve around the first gear 7. The first gear 7 is arranged on the housing 12, the second gear 16 and the third gear 17 are arranged in the hollow structure of the swing arm 13, and the rotating shaft of the first gear 7 is coaxially arranged with the swing rotating shaft of the swing arm 13.

[0053] Furthermore, the cleaning assembly 2 further includes a housing cover 14, which is disposed above the housing 12 to form a cavity structure with an opening, in which the second gear set and part of the swing arm 13 are disposed, and the swing arm 13 extends outward from the opening of the cavity structure. The housing cover 14 is not only convenient for the arrangement of the second gear set, but also can provide protection for the second gear set to prevent foreign matter from jamming the gears.

[0054] In one embodiment of the present application, see Figure 5 and Fig.10 The driving device 3 further includes a reset member 15, one end of which is connected to the housing 12, and the other end is connected to the swing arm 13. The reset member 15 is used to drive the swing arm 13 to reset after swinging outward. Specifically, when the cam drives the swing arm 13 to swing outward, as the proximal end of the cam docks with the swing arm 13, the driving force provided by the reset member 15 can reset the swing arm 13, and the cleaning body 4 also returns to the accommodating groove 21.

[0055] The reset element 15 includes but is not limited to: a spring, a torsion spring, a repelling magnet, etc. Figure 5 and Fig.10 , taking the reset member 15 as a spring as an example, one end of the spring is connected to the housing 12, and the other end is connected to the swing arm 13. When the swing arm 13 swings outward, the spring is stretched, and as the cam rotates, the tension of the spring can reset the swing arm 13.

[0056] In one embodiment provided in the present application, when the cleaning component 2 is not swung outward, that is, the cleaning component 2 is located in the receiving groove 21, it can be considered that the cleaning component 2 is in the initial position. When the cleaning component 2 needs to be reset from the extreme position, it can be reset by the reset member 15 mentioned above, or the drive device 3 can be switched to the first working mode, and then the cleaning component 2 can be swung back from the extreme position to the initial position. After the cleaning component 2 returns to the initial position, the drive device 3 can continue to maintain the first working state, stop working, or switch to other working states.

[0057] See also Figure 5 , Figure 6 , Fig.11 and Fig.12 In one embodiment provided in the present application, the transmission assembly 6 includes a first gear 7, the first gear 7 is meshed with the driving gear on the motor 5, and the first gear set and the second gear set are respectively located on both sides of the first gear 7, and are respectively meshed with the sub-gears on the first gear 7. Specifically, the first gear 7 includes a main gear 71, a first sub-gear 72 and a second sub-gear 73, the first sub-gear 72 is connected to the multi-stage reduction gear to form a first transmission path; the second sub-gear 73 is meshed with the swing gear 8 to form a second transmission path. The first sub-gear 72 and the second sub-gear 73 are respectively located on both sides of the main gear 71, so that the first gear set and the second gear set are stacked, and the structure of the transmission assembly 6 is more compact and occupies less space.

[0058] In the technical solution provided in the present application, one cleaning component 2 or multiple cleaning components 2 may be provided on the device body 1 of the cleaning device, for example, see Figure 1 and Figure 2 , a cleaning assembly 2 is provided on the right side of the front end of the device body 1. For another example, a cleaning assembly 2 can be provided on the left and right sides of the front end of the device, respectively, and the cleaning assembly 2 can effectively clean the garbage on the left and right sides of the device body 1 to the bottom of the device body 1, thereby facilitating the collection of the device.

[0059] In summary, in the technical solution provided in the present application, the cleaning component 2 on the cleaning device can have different working modes due to different structures. Figures 5 to 7 When the main gear 71 and the first sub-gear 72 are an integral structure, and a first one-way bearing 9 is provided between the main gear 71 and the second sub-gear 73, after the driving device 3 is switched from the first working mode to the second working mode, the cleaning assembly 2 will swing outward, and the cleaning assembly 2 will swing back and forth between the initial position and the limit position. In addition, when the cleaning assembly 2 swings outward, the cleaning body 4 on the cleaning assembly 2 will also rotate at the same time, but the rotation direction of the cleaning body 4 is opposite to the rotation direction of the driving device 3 in the first working mode. In this case, the cleaning body 4 can clean in the reverse rotation direction.

[0060] Taking the second structure as an example, see Figure 5 , Figure 6 and Fig. 9, when the first one-way bearing 9 is provided between the main gear 71 and the second sub-gear 73, and the second one-way bearing 10 is provided between the main gear 71 and the first sub-gear 72, the locking directions of the first one-way bearing 9 and the second one-way bearing 10 are opposite. Then when the driving device 3 operates in the first working mode, the second sub-gear 73 does not rotate, and the driving member 11 (cam) does not rotate at this time, and the cleaning body 4 rotates in the forward direction for cleaning. When the driving device 3 operates in the second working mode, the first sub-gear 72 does not rotate, the second sub-gear 73 rotates, and the driving member 11 rotates at the same time, thereby driving the cleaning component 2 to swing outward.

[0061] On the basis of the first structure and the second structure of the cleaning component 2, the one-way bearing mentioned above can be used as a locking device for locking or positioning. For example, when the cleaning component 2 swings to a preset position, the one-way bearing locks it to keep it at the preset position. Of course, an additional locking device can be provided on the cleaning device or the cleaning component 2. When the cleaning component 2 swings outward to a preset position, such as an extreme position, the locking device can lock the cleaning component 2. At this time, regardless of whether the driving device 3 is switched to the first working mode or the second working mode, the cleaning component 2 will not automatically reset. Under the action of the locking device, after the driving device 3 drives the cleaning component 2 to the extreme position in the second working mode, the driving device 3 can switch to the first working mode. At this time, the cleaning component 2 can be realized in the state of swinging outward, and the cleaning body 4 thereon rotates forward for cleaning.

[0062] When the cleaning assembly 2 needs to be reset, the locking device is unlocked, and then the cleaning assembly 2 is reset to the initial position under the action of the reset member 15, or the driving device 3 is switched to the second working mode.

[0063] In one embodiment provided in the present application, a locking device is provided between the device body 1 and the cleaning assembly 2 of the cleaning device. When the cleaning assembly 2 is swung outward to the extreme position, the locking device can lock the cleaning assembly 2 with the device body 1, so that the cleaning assembly 2 is always in the state of being swung outward. When the cleaning assembly 2 needs to be reset, the locking device is unlocked, the cleaning assembly 2 is disconnected from the locking position of the device body 1, and then the cleaning assembly 2 can be reset.

[0064] Furthermore, the locking device includes a locking structure and a power component. The locking structure includes a lock body and a lock tongue. The power component is connected to the lock body to drive the lock body to unlock. The lock tongue is arranged on the outer shell of the cleaning component 2, such as the swing arm upper cover 131 or the swing arm lower cover 132. The lock body is arranged on the device body 1. When the cleaning component 2 is swung outward to the extreme position, the lock tongue is inserted into the lock body to achieve locking. When unlocking is required, the power component drives the lock body to move to achieve unlocking, and the lock tongue is disconnected from the lock body. The power component includes but is not limited to: a motor, an electromagnet, an electromagnetic switch, etc.

[0065] See also Figures 3 to 12 In one embodiment of the present application, a cleaning assembly is also provided, which includes a shell 12, a driving device 3 and a cleaning body 4. The driving device 3 is arranged on the shell 12. The shell 12 is also provided with a mounting portion for connecting with the equipment body 1 of the cleaning device. The driving device 3 can drive the cleaning body 4 to rotate, and is used to sweep the garbage on the side of the equipment body 1 to the bottom of the equipment body 1. The driving device 3 has at least two working modes. In the first working mode, the driving device 3 outputs power to drive the cleaning body 4 to rotate; in the second working mode, the driving device 3 outputs reverse power to drive the cleaning body 4 to swing outward, so as to clean an area farther outside the side of the equipment body 1. When the cleaning body 4 is in the outward swing state, the cleaning body 4 can be in a stopped rotation state, and the cleaning body 4 can also be in a state of rotating together with the swing.

[0066] Furthermore, when the driving device 3 is in the second working mode, the driving device 3 drives the cleaning body 4 to swing outwards in a circular reciprocating manner. Alternatively, the driving device 3 drives the cleaning body 4 to swing outwards to an extreme position and then locks. Generally, in order to realize the cleaning function of the cleaning body 4, when the cleaning body 4 swings back and forth in a circular reciprocating manner, the cleaning body 4 can realize the cleaning function regardless of whether the cleaning body 4 rotates on its own. When the cleaning body 4 swings outwards to an extreme position and is locked, the cleaning body 4 must rotate on its own to realize the cleaning function.

[0067] Furthermore, the drive device 3 includes a motor 5 and a transmission assembly 6. The motor 5 is arranged on the housing 12. The motor 5 can output rotational power in different directions so that the drive device 3 works in the first working mode or the second working mode. In a specific implementation, the motor 5 rotates forward and the drive device 3 works in the first working mode. When the cleaning body 4 needs to clean an area farther from the side of the device body 1, it only needs to control the motor 5 to reverse, and the drive device 3 will switch to the second working mode. At this time, the cleaning body 4 swings outward to clean an area farther from the side of the device body 1.

[0068] Furthermore, the driving device 3 further comprises a transmission assembly 6, which comprises a plurality of gear sets, and the plurality of gear sets are divided into two transmission paths. When the driving device 3 works in the first working mode, the transmission assembly 6 transmits the rotational power of the motor 5 to the cleaning body 4 via the first transmission path to drive the cleaning body 4 to rotate. When the driving device 3 works in the second working mode, the transmission assembly 6 transmits the reverse rotational power of the motor 5 to the cleaning body 4 via the second transmission path to drive the cleaning body 4 to swing, or drive the cleaning body 4 to swing and rotate simultaneously.

[0069] For other specific structures of the cleaning component, please refer to the description of the cleaning component above, which will not be repeated here.

[0070] See also Fig.13In one embodiment of the present application, a cleaning device working method is also provided. The working method is applicable to the above-mentioned cleaning device or cleaning component. The working method of the cleaning device comprises the following steps:

[0071] S101, the driving device works in a first working mode, and the driving device drives the cleaning body to rotate;

[0072] S102, based on the outward swing cleaning instruction, the driving device switches from the first working mode to the second working mode, and the driving device drives the cleaning component to swing outward;

[0073] S103, after the cleaning assembly swings outward to a preset position, the driving device switches to a first working mode;

[0074] In step S101 , when the driving device 3 works in the first working mode, the driving device 3 drives the cleaning body 4 to rotate, and it can be considered that the cleaning body 4 of the cleaning assembly 2 cleans in a forward rotating manner.

[0075] In step S102, after receiving the instruction for the cleaning component 2 to swing outward, the driving device 3 will change the working mode from the first working mode to the second working mode. At this time, the transmission component 6 drives the cleaning component 2 to swing outward through the second transmission path. During the process of the cleaning component 2 swinging outward, the first transmission path of the transmission component 6 can be in a connected state or a disconnected state. When the transmission path of the transmission component 6 is in a connected state, the cleaning body 4 on the cleaning component 2 will also rotate at the same time during the process of the cleaning component 2 swinging outward, and the rotation direction of the cleaning body 4 is in the opposite direction. When the first transmission path is in a disconnected state, the cleaning body 4 does not rotate during the process of the cleaning component 2 swinging outward.

[0076] As mentioned above, when a locking device is provided on the cleaning device, the cleaning component 2 can be swung outward to a preset position, and then the driving device can be switched to the first working mode.

[0077] Furthermore, the preset position can be the extreme position in the outward swing state, or any position between the initial position and the extreme position. As mentioned above, the cleaning device is also provided with a locking device. When the cleaning component 2 is swung outward to the preset position, the locking device can lock the cleaning component 2, and then the cleaning component 2 can always remain in the preset position. In this case, the driving device can be switched to the first working mode or the second working mode at will. When the cleaning component 2 needs to be reset, the locking device is controlled to be unlocked, and the cleaning component 2 can be reset from the extreme position to the initial position.

[0078] In addition, when the cleaning device is not provided with a locking device, when the driving device 3 drives the cleaning component 2 to swing outward, as the driving device 3 continues to work in the second working mode, the cleaning component 2 will move in a reciprocating outward swinging manner.

[0079] Furthermore, in an embodiment provided in the present application, the working method of the cleaning device further includes the following steps:

[0080] S104, based on the external swing cleaning end instruction, the cleaning component is reset from the preset position to the initial position;

[0081] S105, when the cleaning component is reset to the initial position, the driving device stops working; or the driving device maintains the first working mode.

[0082] In the above steps, after the cleaning device completes the edge cleaning, the cleaning component 2 usually needs to be retracted to reduce the probability of collision between the cleaning component 2 and the obstacle. When the cleaning component 2 needs to be retracted, the cleaning device outputs an instruction to end the external swing cleaning, and then the locking device can be unlocked, and then the cleaning component 2 will be reset from the extreme position to the initial position. In the process of resetting the cleaning component 2, the reset member 15 mentioned above can drive the cleaning component 2 to reset, or the driving device 3 can work in the first working mode to drive the cleaning component 2 to reset.

[0083] Furthermore, the retraction of the cleaning component 2 can be performed after the cleaning device completes the edge cleaning, or the cleaning device can be in the state of swinging outward during the entire cleaning task. For example, after the cleaning is completed, the cleaning component 2 is retracted, and then the driving device 3 stops working. In addition, when the cleaning component 2 needs to be retracted after completing the edge cleaning, after the cleaning component 2 is retracted, the driving device 3 switches to the first working mode again, and then the cleaning body 4 cleans the floor in a forward rotation manner.

[0084] Furthermore, the above step S104: "Based on the instruction to end the external swing cleaning, the locking device is unlocked, and the cleaning component is reset from the extreme position to the initial position;" also includes the following steps:

[0085] S1041, when the driving device switches from the first working mode to the second working mode, the driving device drives the cleaning body to rotate in the reverse direction;

[0086] S1041', the cleaning body does not rotate.

[0087] As mentioned above, when the main gear 71 and the first sub-gear 72 are an integrated structure, after the driving device 3 is switched to the second working mode, the cleaning body 4 on the cleaning assembly 2 will also change the rotation direction, and it will perform the cleaning operation in a reverse rotation manner. When a second one-way bearing 10 is provided between the main gear 71 and the first sub-gear 72, then when the driving device 3 works in the second working mode, the first transmission path of the transmission assembly 6 will be interrupted, and the cleaning body 4 on the cleaning assembly 2 will not rotate.

[0088] In order to facilitate the understanding of the technical solution of the present application, a specific application scenario is given below to describe the technical solution of the present application in detail.

[0089] Application scenario 1

[0090] When the sweeping robot is performing cleaning operations, the cleaning component can sweep the garbage on the side of the robot to the bottom of the sweeping robot, which is then collected by the dust collection device on the sweeping robot. When the sweeping robot is cleaning the area at the foot of the wall, the cleaning robot can sweep the garbage at the foot of the wall to the bottom of the sweeping robot through the continuous rotation of the side brush without its shell touching the wall, thereby effectively reducing the area of ​​the sweeping robot's cleaning blind spot. As the sweeping robot continues to move, the sweeping robot will also encounter corner areas. At this time, the front and sides of the sweeping robot are walls. In this case, the cleaning blind area of ​​the corner area is larger. At this time, the sweeping robot only needs to control the motor in the drive device to rotate in the opposite direction, and the cleaning component will swing outward, so that it can clean areas farther outside the side of the sweeping robot, and the area of ​​the cleaning blind spot will be effectively reduced.

[0091] Application scenario 2

[0092] In a home environment, there are various obstacles on the ground. Usually, the edge areas of obstacles are blind spots for the sweeping robot. At this time, the motor on the cleaning component outputs reverse driving force, and the side brush will swing outward, so that the side brush can clean the area farther outside the sweeping robot. While preventing the outer shell of the sweeping robot from contacting obstacles, the side brush can also sweep the garbage at the edge of the obstacle to the bottom of the sweeping robot, which will then clean and collect it.

[0093] In summary, in the technical solution provided in the present application, the cleaning body on the cleaning assembly can not only rotate to sweep the garbage on the side of the cleaning device to the bottom of the device body, but the cleaning body can also swing outward to sweep to an area farther outside the side of the device body, thereby solving the problem of cleaning corners. In addition, only one motor needs to be provided on the cleaning assembly, and the driving device can be switched between the first working mode and the second working mode by changing the direction of the motor. The side brush can be changed to the outward swing state conveniently and quickly, and there is no need to set up other power devices to drive the cleaning body to swing outward. The driving device has a relatively simple structure, occupies less space, and has a lower cost.

[0094] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
