[0060] The cleaning device provided by one embodiment of the present application includes a push rod (not shown in the figure), a body 100, a roller 200, a driving member (not shown in the figure) and a first actuator 300. The push rod is a U-shaped rod, and both ends of the U-shaped rod are rotatably connected to the body 100 through a rotating mechanism, and the roller 200 is rotatably connected to the body 100. When the push rod is pushed by the user to make the cleaning device move forward, the roller 200 rotates in a preset direction; the driving member is installed on the body 100; the first actuator 300 is detachably connected to the body 100, and the first actuator 300 includes a first transmission assembly 310 and a first actuator assembly 320; the first transmission assembly 310 includes an outer gear ring 311 and a planetary gear set 312 that cooperate with each other. ; The planetary gear set 312 includes a sun gear 3121 and at least one planetary gear 3122, and the sun gear 3121 and at least one planetary gear 3122 are meshed for transmission; one end of the sun gear 3121 is connected to the power output end of the driving member, the outer ring gear 311 is meshed for transmission with at least one planetary gear 3122, and the outer ring gear 311 is fixedly connected to the first actuator 320; when the cleaning device is pushed and moved forward, the rotation direction of the first actuator 320 is opposite to the rotation direction of the roller 200, that is, the preset direction.

[0061] When the cleaning device is used to clean leaves, the first actuator 300 can be selected as a leaf sweeping brush mechanism, and the first actuator assembly 320 is a leaf sweeping brush assembly. When the roller 200 rotates in a preset direction, that is, along the travel direction of the cleaning device, the outer gear ring 311 of the first actuator 300 and the planetary gear set 312 cooperate to make the rotation direction of the first actuator assembly 320 opposite to the rotation direction of the power output end of the driving member, and opposite to the rotation direction of the roller 200. When the cleaning device moves along the travel direction, the first actuator assembly 320 can sweep up the leaves on the ground and then throw them against the travel direction into the collection box at the rear of the cleaning device, reducing the possibility of the leaves on the ground being swept up and thrown out along the travel direction of the cleaning device, so that the cleaning device has a better cleaning effect, less time is needed for cleaning, higher efficiency, and better economic benefits.

[0062] It should be noted that the roller 200 can be rotated by manual driving or by a driving member such as a motor. The direction in which the roller 200 rotates around a preset direction is the direction in which the cleaning device normally moves.

[0063] The following is a detailed description of the structure of the cleaning device. Figure 9-Figure 15 . Fig. 9 Shows Figure 7 A local enlarged view of point C is shown. Fig.10 Shows Figure 3FIG. 1 is a schematic diagram of an outer gear ring 311 in the first actuator 300 .

Fig.12 Shows Figure 3 A first angle schematic diagram of the second blade sweeping brush ring 322 in the first actuator 300 is shown. Fig.13 Shows Figure 3 A second angle schematic diagram of the second blade sweeping brush ring 322 in the first actuator 300 is shown. Fig.14 Shows Figure 3 A schematic diagram of the third sweeping brush ring 323 in the first actuator 300 is shown. Fig.15 Shows Figure 8 A schematic diagram of the transmission shaft 313 in the first actuator 300 is shown.

[0064] See also Figure 5 , Figure 6 , Figure 8 and Fig.11 , the first actuator 320 of the cleaning device provided in one embodiment of the present application is configured with a mounting portion 3211 on one side close to the outer gear ring 311; please refer to Figure 8 The cleaning device also includes a connecting member 500, which passes through the mounting portion 3211 and is fixedly connected to the outer gear ring 311. The connecting member 500 enables the first actuator 320 to be fixedly connected to the outer gear ring 311, so that when the planetary gear set 312 drives the outer gear ring 311 to rotate, it can drive the first actuator 320 to rotate, thereby achieving the function of cleaning leaves. Specifically, the connecting member 500 is arranged on the first leaf sweeping brush ring 321, and the connecting member 500 enables the outer gear ring 311 to be fixedly connected to the first leaf sweeping brush ring 321, and enables the outer gear ring 311 and the first leaf sweeping brush ring 321 to maintain a consistent movement direction in both the axial direction and the circumferential direction.

[0065] See also Figure 8 and Fig.10 , the outer gear ring 311 of the cleaning device provided in one embodiment of the present application is provided with a first clamping portion 3111 protruding outwardly along its axial direction; please refer to Figure 8 Combined with Fig.11 The first actuator 320 of the cleaning device provided in one embodiment of the present application is provided with a clamping ring 3212 on one side close to the outer gear ring 311, and the first clamping portion 3111 can at least partially extend into the inside of the clamping ring 3212. Through the clamping cooperation between the first clamping portion 3111 and the clamping ring 3212, the installation of the outer gear ring 311 and the first actuator 320 is more time-saving and convenient, and the alignment of the mounting member with the mounting hole 410 on the outer gear ring 311 is faster and more convenient during installation.

[0066] See also Figure 8 and Fig.10 The number of the first clamping parts 3111 of the cleaning device provided in one embodiment of the present application is at least two, and at least two first clamping parts 3111 are arranged at intervals along the circumference of the outer gear ring 311; the shape of the clamping ring 3212 is adapted to the shape of the first clamping part 3111. By providing at least two first clamping parts 3111, after the outer gear ring 311 and the first actuator 320 are matched, the clamping area between the two is larger and the clamping is more stable.

[0067] See also Figure 6 , Figure 8 and Fig.10 , the installation portion 3211 of the cleaning device provided in an embodiment of the present application extends inwardly along the radial direction of the first actuator 320 toward one side of the inner part of the outer gear ring 311, until at least a part of the installation portion 3211 enters between two adjacent first clamping portions 3111, so that when the outer gear ring 311 where the installation portion 3211 is located rotates, it drives the first actuator 320 to rotate. Through such an arrangement, the clamping connection between the outer gear ring 311 and the first actuator 320 is relatively stable. At the same time, such an arrangement can also make it possible for the outer gear ring 311 to input radial torque to the first actuator 320 through the cooperation of the first clamping portion 3111, the clamping ring 3212 and the installation portion 3211, and the cooperation of the connecting member 500 and the installation portion 3211 when the outer gear ring 311 rotates, so that the first actuator 320 can rotate synchronously with the outer gear ring 311.

[0068] See also Figure 8 , Fig. 9 and Fig.15 The first transmission assembly 310 of the cleaning device provided in one embodiment of the present application further includes a transmission shaft 313, and the first actuator assembly 320 is sleeved on the transmission shaft 313; please refer to Figure 2 , Figure 3 and Figure 7 The first actuator 320 of the cleaning device provided in one embodiment of the present application includes a plurality of leaf sweeping brush rings connected in sequence, and the plurality of leaf sweeping brush rings are arranged in sequence and connected to each other along the axial direction of the transmission shaft 313. By providing a plurality of leaf sweeping brush rings connected in sequence, the cleaning device can simultaneously sweep leaves within a relatively long range.

[0069] See also Figure 3 , Figure 7 and Figure 8 The cleaning device provided in one embodiment of the present application has a first leaf sweeping brush ring close to the outer gear ring 311 as the first leaf sweeping brush ring 321, and a second leaf sweeping brush ring 322 is fixedly connected to the side of the first leaf sweeping brush ring 321 away from the outer gear ring 311; please refer to Figure 8 and Fig.15The transmission shaft 313 is provided with a second clamping portion 3131 protruding radially outward, and the second leaf sweeping brush ring 322 is configured with a first clamping groove 3221, and the second clamping portion 3131 is inserted into the first clamping groove 3221. By fixedly connecting the first leaf sweeping brush ring 321 and the second leaf sweeping brush ring 322, and clampingly connecting the second leaf sweeping brush ring 322 and the transmission shaft 313, the first leaf sweeping brush ring 321 and the transmission shaft 313 are fixed, and the first leaf sweeping brush ring 321 is not easy to move along the axial direction of the transmission shaft 313, so that the first leaf sweeping brush ring 321 is not easy to abut against the external handle 400 and mutually wear with the handle 400 during its own rotation, and the service life of the first leaf sweeping brush ring 321 and the handle 400 is longer. For details, please refer to Fig.12 The opening of the first clamping groove 3221 on the second leaf sweeping brush ring 322 faces the first leaf sweeping brush ring 321, and when the second clamping portion 3131 is located in the first clamping groove 3221, the second clamping portion 3131 prevents the second leaf sweeping brush ring 322 from moving toward the first leaf sweeping brush ring 321; further, since the first leaf sweeping brush ring 321 and the second leaf sweeping brush ring 322 are fixedly connected by screws, when the second leaf sweeping brush ring 322 is prevented from moving toward the first leaf sweeping brush ring 321, the first leaf sweeping brush ring 321 fixedly connected to the second leaf sweeping brush ring 322 is also prevented from moving toward the handle 400.

[0070] See also Fig.11 The first leaf sweeping brush ring 321 of the cleaning device provided in one embodiment of the present application is provided with a clamping column 3213 on one side close to the second leaf sweeping brush ring 322. Fig.12 The second leaf sweeping brush ring 322 is configured with a third clamping groove 3222 on one side close to the first leaf sweeping brush ring 321, and the clamping column 3213 is clamped into the third clamping groove 3222, and a screw is driven into the clamping column 3213 from one side of the third clamping groove 3222, so that the first leaf sweeping brush ring 321 and the second leaf sweeping brush ring 322 are fixedly connected by screws, so that the second leaf sweeping brush ring 322 can pull the first leaf sweeping brush ring 321 to prevent the first leaf sweeping brush ring 321 from moving toward the handle 400, and the torque can be transmitted through the cooperation between the clamping column 3213 and the third clamping groove 3222.

[0071] See also Figure 3 and Figure 7The second leaf sweeping brush ring 322 of the cleaning device provided in an embodiment of the present application is connected to a plurality of third leaf sweeping brush rings 323 on the side facing away from the first leaf sweeping brush ring 321, and the plurality of third leaf sweeping brush rings 323 are clamped together; and the third leaf sweeping brush ring 323 close to the second leaf sweeping brush ring 322 is clamped with the second leaf sweeping brush ring 322. By clamping the plurality of third leaf sweeping brush rings 323 together and clamping with the second leaf sweeping brush ring 322, the connection between the third leaf sweeping brush rings 323 and the connection between the third leaf sweeping brush ring 323 and the second leaf sweeping brush ring 322 is simpler, more convenient and time-saving.

[0072] Specifically, the structure of the second leaf sweeping brush ring 322 facing away from the first leaf sweeping brush ring 321 is the same as the structure of the third leaf sweeping brush ring 323 facing away from the second leaf sweeping brush ring 322. Fig.13 The inner side of the second sweeping leaf brush ring 322 is protruded toward the third sweeping leaf brush ring 323 to provide a third clamping portion 3223, and the third clamping portion 3223 is two clamping columns; accordingly, please refer to Fig.14 The third leaf sweeping brush ring 323 is provided with a second clamping groove 3231 on one side facing the second leaf sweeping brush ring 322. When the second leaf sweeping brush ring 322 and the third leaf sweeping brush ring 323 are assembled together along the axial sleeve of the transmission shaft 313, the third clamping portion 3223 is clamped into the second clamping groove 3231, so that the second leaf sweeping brush ring 322 and the third leaf sweeping brush ring 323 are clamped, and at the same time, the second leaf sweeping brush ring 322 inputs torque to the third leaf sweeping brush ring 323 through the clamping structure, so that when the second leaf sweeping brush ring 322 rotates, the second leaf sweeping brush ring 322 drives the third leaf sweeping brush ring 323 to rotate through the clamping structure. In addition, a plurality of third leaf sweeping brush rings 323 are also assembled and torque transmission is achieved through the clamping structure as described above.

[0073] See also Fig. 9 The first transmission assembly 310 of the cleaning device provided in one embodiment of the present application further includes an end cover 314, which is disposed on a side of the first actuator 320 away from the planetary gear set 312, and is used to limit the movement of the plurality of third leaf sweeping brush rings 323 along the axial direction of the transmission shaft 313 toward a side away from the outer gear ring 311. By providing the end cover 314, the end cover 314 limits the axial movement of the third leaf sweeping brush rings 323 along the transmission shaft 313, thereby making it difficult for the position of the entire first actuator 320 relative to the transmission shaft 313 to change, and the position accuracy of the first actuator 320 relative to the transmission shaft 313 is high. When cleaning leaves through an actuator, the entire cleaning device is more stable and smooth.

[0074] See also Fig. 9The first transmission assembly 310 of the cleaning device provided in one embodiment of the present application further includes a limiting gasket 315, which is sleeved on the transmission shaft 313 and arranged on the side of the end cover 314 away from the third sweeping brush ring 323, and the diameter of the limiting gasket 315 is larger than the inner hole diameter of the end cover 314. By providing the limiting gasket 315, the end cover 314 is prevented from moving toward the side away from the outer gear ring 311, so as to better limit the third sweeping brush ring 323.

[0075] See also Fig. 9 The first transmission assembly 310 of the cleaning device provided in one embodiment of the present application also includes a weed-proof gasket 319, which abuts between the end cover 314 and the limiting gasket 315, and the inner hole diameter of the weed-proof gasket 319 is smaller than the outer circumferential size of the limiting gasket 315. The weed-proof gasket 319 is used to prevent grass or other debris from entering the interior of the transmission shaft 313 to cause damage to the transmission shaft 313.

[0076] See also Figure 3 and Figure 4 The planetary gear set 312 of the cleaning device provided in one embodiment of the present application further includes a planetary frame 3123, the planetary frame 3123 is fixedly connected to the body 100, and the planetary gear 3122 is mounted on the planetary frame 3123. By mounting the planetary gear 3122 on the planetary frame 3123, the planetary gear 3122 can rotate around its own rotation axis on the planetary frame 3123. Specifically, a mounting column is convexly provided on the planetary frame 3123, and the planetary gear 3122 is sleeved on the mounting column and can rotate relative to the mounting column.

[0077] See also Figure 1 , Figure 2 and Figure 8The cleaning device provided in one embodiment of the present application further includes a handle 400, which is fixedly connected to the planet carrier 3123. The handle 400 has a snap-fit ​​position relative to the machine body 100, and in the snap-fit ​​position, the handle 400 can be fixed relative to the machine body 100. When the cleaning device is used to take care of the garden and leaves need to be cleaned in the garden, the first actuator 300 is installed on the machine body 100, and one end of the sun gear 3121 is connected to the power output end of the driving member, and the handle 400 is moved to the snap-fit ​​position so that the handle 400 is fixed relative to the machine body 100. At this time, the driving member drives the sun gear 3121 to rotate, thereby driving the planetary gear set 312 to rotate, and then driving the outer gear ring 311 meshing with the planetary gear set 312 to rotate, thereby driving the first leaf sweeping brush ring 321 and the second leaf sweeping brush ring 322 fixedly connected to the first leaf sweeping brush ring 321 to rotate, and then driving the third leaf sweeping brush ring 323 engaged with the second leaf sweeping brush ring 322 to rotate, so that the entire leaf sweeping brush rotates. It should be noted that the handle 400 also has an unlocking position relative to the body 100. When the handle 400 rotates around the rotation axis of the transmission shaft 313, it can be switched from the unlocking position to the engaging position. In one specific embodiment, the handle 400 is fixedly connected to the planetary frame 3123 by a bolt connector.

[0078] Specifically, the handle 400 includes a disc portion 420 covering the opening of the outer gear ring 311 on the side facing the driving member, an extension portion 430 extending radially outward from the disc portion 420, and a handle portion 440 extending from the extension portion 430 in a direction perpendicular to the extension portion 430 in a direction away from the first actuator 300. When the handle 400 is in the clamping position, the handle portion 440 enters the installation space of the body 100. When the first actuator 300 is working, the first actuator 300 rotates around its own axis, and the limiter on the body 100 can prevent the handle portion 440 from rotating out of the installation space.

[0079] Since the handle 400 is provided with the handle portion 440 , when the first actuator 300 is detached from the body 100 , the user can move the first actuator 300 away by holding the handle portion 440 of the handle 400 .

[0080] It should be noted that when the output speed of the driving member is high and the speed required by the first actuator 320 is low, the planetary gear set 312 can also be used as a speed reduction component. When the output speed of the driving member is low and the speed required by the first actuator 320 is high, the planetary gear set 312 can also be used as a speed increase component, and there is no special limitation on this.

[0081] See also Figure 3-Figure 5The first transmission assembly 310 of the cleaning device provided in one embodiment of the present application further includes an anti-wear pad 316, which abuts between the planetary gear 3122 and the handle 400 along the axial direction of the transmission shaft 313. By providing the anti-wear pad 316, when the cleaning device is working, the planetary gear 3122 is less likely to move along the axis of the transmission shaft 313 and separate from the planetary carrier 3123; at the same time, the ends of the planetary gear 3122 and the handle 400 can be effectively protected, so that the ends of the planetary gear 3122 and the handle 400 adjacent to each other are not easily worn.

[0082] See also Figure 3 , Figure 4 and Figure 8 The first transmission assembly 310 of the cleaning device provided in one embodiment of the present application further includes a bearing 317, the inner ring of which is sleeved on the power output end of the driving member; the handle 400 is provided with a mounting hole 410, and the bearing 317 is at least partially accommodated in the mounting hole 410. The bearing 317 has a supporting function for the power output end of the driving member to support its driving rotation action for the sun gear 3121.

[0083] See also Figure 3 , Figure 4 and Figure 8 The first transmission assembly 310 further includes a clamping member 318, which is sleeved on the transmission shaft 313 and is disposed at an end of the bearing 317 away from the driving member. By providing the clamping member 318, the clamping member 318 limits the bearing 317 to prevent the bearing 317 from moving along the axial direction of the transmission shaft 313.

[0084] In the cleaning device provided in the present application, the first actuator can be disassembled and replaced with a second actuator to achieve another function. In some embodiments, the second actuator can be a grass combing mechanism.

[0085] When the cleaning device is installed with the first actuator 300, the first actuator assembly 320 of the first actuator 300 can automatically rotate in the opposite direction to the direction in which the cleaning device is pushed forward, so as to facilitate the leaf sweeping operation. When the cleaning device is installed with the second actuator, the second actuator can rotate in the same direction as the direction in which the cleaning device is pushed forward, so as to facilitate the grass combing or other functions.

[0086] In one embodiment, the rotation speed of the second actuator is different from the rotation speed of the first actuator 320. By setting the rotation speed of the second actuator to be different from the rotation speed of the first actuator 320, the cleaning device can adapt to the rotation speed required by different actuators, which is simple and convenient. For example, the rotation speed output by the driving member is 4000 revolutions per second, the rotation speed of the first actuator 320 is 250 revolutions per second, and the rotation speed of the second actuator is 4000 revolutions per second.

[0087] In one embodiment, the cleaning mechanism further includes a third actuator (not shown in the figure), the third actuator is detachably connected to the body 100, and the third actuator includes a third transmission assembly and a third actuator assembly; the third transmission assembly can be connected to the power output end of the driving member, and the third transmission assembly is connected to the third actuator assembly. Optionally, when the second actuator assembly is a loosening blade assembly, the third actuator assembly is a grass combing assembly. And when the second actuator assembly is a grass combing assembly, the third actuator assembly is a loosening blade assembly.

[0088] When taking care of the garden by the above-mentioned cleaning mechanism, the first transmission assembly 310, the second transmission assembly and the third transmission assembly can be detachably connected to the power output end of the driver. Therefore, when different actuators are connected to the power output end of the driver, different care work can be performed on the garden. For example, when it is necessary to perform a grass combing operation on the garden, the third actuator is a grass combing brush at this time, and the third transmission assembly is connected to the power output end of the driver, so that the grass combing operation is performed by the third actuator. And when the grass combing operation is completed, when it is necessary to perform a leaf sweeping operation, the third transmission assembly is detached from the driver at this time, the first transmission assembly 310 is connected to the power output end of the driver, and the first actuator 320 is a leaf sweeping brush, so that the leaf sweeping operation is performed by the first actuator 320. And when the leaf sweeping operation is completed, when it is necessary to perform a soil loosening operation, the first transmission assembly 310 is detached from the driver, the second transmission assembly is connected to the power output end of the driver, and the second actuator is a soil loosening blade, and then the soil loosening operation is performed on the garden.

[0089] When the cleaning mechanism is used to take care of the garden, the operations of loosening the soil, combing the grass and sweeping the leaves can be completed by one device, without the need to spend extra money to purchase different equipment. It is more economical and saves more storage space, thus realizing the function of one machine with multiple uses.

[0090] See also Figure 4The number of the planetary gears 3122 of the cleaning device provided in one embodiment of the present application is three. The three planetary gears 3122 are arranged at intervals along the circumference of the sun gear 3121 and mesh with the sun gear 3121 for transmission. When the sun gear 3121 rotates around its own rotation axis, it can drive the multiple planetary gears 3122 to rotate around its own rotation axis, so as to drive the outer gear ring 311 to rotate around its own rotation axis and in the direction opposite to the rotation direction of the sun gear 3121. The rotation direction of the first actuator 320 is opposite to the rotation direction of the power output end of the driving member, and is also opposite to the preset rotation direction of the roller 200. When the cleaning device moves along the travel direction, the first actuator 320 can sweep up the leaves on the ground and then throw them into the collection box of the cleaning device against the travel direction, so that the cleaning device has a better cleaning effect, takes less time to clean, has higher efficiency, and has better economic benefits.

[0091] In another specific embodiment, the number of the planetary gears 3122 is four, and the four planetary gears 3122 are arranged at intervals along the circumference of the sun gear 3121. It should be noted that there is no special limitation on the number of the planetary gears 3122, which can be two, five or six, etc. The number of the planetary gears 3122 is adaptively increased or decreased according to the number of teeth of each planetary gear 3122 and the sun gear 3121 and the required speed ratio.

[0092] In one embodiment, the speed ratio of the sun gear 3121 to the outer ring gear 311 is 3:1-4:1. By setting the speed ratio of the sun gear 3121 to the outer ring gear 311 to be within the range of 3:1 to 4:1, the speed output by the drive member can be effectively reduced to better meet the lower speed requirement of the first actuator 320, that is, the leaf brush. In one specific embodiment, the speed ratio of the sun gear 3121 to the outer ring gear 311 is 4:1, and in another specific embodiment, the speed ratio of the sun gear 3121 to the outer ring gear 311 is 3:1. In another specific embodiment, the speed ratio of the sun gear 3121 to the outer ring gear 311 is 3.5:1.

[0093] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
