Technical Field

[0002] In the field of gardening, it is usually necessary to take care of the garden through a cleaning mechanism. For example, the soil is loosened, dead grass is combed out, or leaves are cleaned. Since the speed required by the leaf sweeping component in the cleaning mechanism to clean the leaves is significantly different from the speed of the soil loosening component and the grass combing component, a speed change group is installed on the leaf sweeping component to change the speed of the leaf sweeping component to achieve the required speed requirement. However, during the speed change process, the speed change group is prone to transmission failure, which makes it difficult for the cleaning mechanism to effectively ensure the continuity of cleaning when cleaning the leaves.

[0055] A cleaning mechanism provided in one embodiment of the present application includes a body 100, a driving member (not shown in the figure), a first actuator assembly 200 and a clamping member 300. The driving member is mounted on the body 100; the first actuator assembly 200 includes a first rotating shaft 210, a first actuator 220 and a speed group 230; the first actuator 220 is sleeved and fixedly connected to the first rotating shaft 210; a mounting cavity 221 is configured on one side of the first actuator 220 close to the speed group 230, and the mounting cavity 221 is used to accommodate the speed group 230; the speed group 230 includes an inner gear ring 233 and a planetary gear set that cooperate with each other, and one end of the planetary gear set can be connected to the power output end of the driving member. The connection is disassembled, and the other end of the planetary gear set is installed on the first rotating shaft 210 and is transmission connected to the first rotating shaft 210. The driving member can drive the planetary gear set to rotate to drive the first rotating shaft 210 to rotate around its own rotating axis; the clamping member 300 is fixedly connected to the outer wall of the inner gear ring 233, and the clamping member 300 has a clamping position relative to the body 100. In the clamping position, the clamping member 300 can be fixed relative to the body 100 to fix the inner gear ring 233 relative to the body 100.

[0056] When the garden is taken care of by the above-mentioned cleaning mechanism and leaves need to be cleaned in the garden, the first actuator 220 is set as a leaf sweeping brush, the planetary gear set is connected to the power output end of the driving member, and the clamping member 300 is moved to the clamping position so that the clamping member 300 is fixed relative to the body 100. At this time, the driving member drives the planetary gear set to rotate, and the planetary gear set changes the speed of the driving member and drives the first rotating shaft 210 to rotate around its own rotating axis, thereby making the first actuator 220 fixed on the first rotating shaft 210, that is, the leaf sweeping brush, perform the leaf sweeping operation. During this process, since the clamping piece 300 is fixedly connected to the outer wall of the inner ring gear 233 and the clamping piece 300 is fixed relative to the body 100, the inner ring gear 233 is fixed relative to the body 100. Therefore, during the transmission process of the planetary gear set, the transmission failure of the speed change group 230 caused by the rotation of the inner ring gear 233 and the non-rotation of the planetary gear will not occur. This ensures that the cleaning mechanism can effectively ensure the continuity of cleaning when cleaning leaves.

[0057] By constructing the installation cavity 221 on the first actuator 220, a space is provided for the transmission group 230 to be installed, so that the transmission group 230 can be installed on the first rotating shaft 210. In other words, the end of the first actuator 220 wraps the transmission group 230 to prevent the transmission group 230 from being contaminated or damaged by grass clippings or stones during operation, thereby providing good protection for the transmission group 230.

[0058] It should be noted that when the output speed of the driving member is high and the speed required by the first actuator 220 is low, the planetary gear set is a speed reduction component. When the output speed of the driving member is low and the speed required by the first actuator 220 is high, the planetary gear set is a speed increase component, and there is no special limitation on this.

[0059] See also Figure 8 , Figure 8 Shows Figure 1 A schematic diagram of the clamping member 300 of the cleaning mechanism is shown. In one embodiment, a mounting hole 310 is constructed on the clamping member 300, and a locking member such as a screw or a bolt passes through the mounting hole 310 and is connected to the inner gear ring 233, thereby achieving a fixed connection between the clamping member 300 and the inner gear ring 233.

[0060] The following is a detailed description of the cleaning mechanism. Figure 3The cleaning mechanism provided in one embodiment of the present application has a mounting groove 110 with an opening on the body 100; the cleaning mechanism also includes a stopper 400, which is installed in the mounting groove 110; when the clamping member 300 is in the clamping position, the clamping member 300 can at least partially extend into the mounting groove 110, and the stopper 400 can limit the rotation of the clamping member 300 relative to the rotation axis of the first rotation shaft 210. When the first actuator 200 is cleaning leaves in the garden, the first actuator 220 on the first actuator 200 moves along the rotation axis of the first rotation shaft 210. Figure 3 The clamping member 300 is rotated in the counterclockwise direction indicated by the R arrow in the figure, and the clamping member 300 abuts against the groove wall of the installation groove 110 at the clamping position. The groove wall of the installation groove 110 is limited so that the clamping member 300 will not move along the Figure 3 The stopper 400 can limit the clamping member 300 from rotating in the counterclockwise direction indicated by the R arrow in FIG. Figure 3 The first actuator 200 rotates in the clockwise direction, so that when the first actuator 200 performs a leaf cleaning operation on the garden, the clamping member 300 is not easy to rotate around the axis of the first rotating shaft 210, and the position of the clamping member 300 relative to the body 100 is not easy to change, so that the inner ring gear 233 connected to the clamping member 300 has a better fixing effect relative to the body 100. During the transmission process of the planetary gear set, the transmission failure of the speed change group 230 caused by the rotation of the inner ring gear 233 and the non-rotation of the planetary gear will not occur, so that the present cleaning mechanism can effectively ensure the continuity of cleaning when cleaning leaves.

[0061] See also Figure 3The limiting member 400 of the cleaning mechanism provided in one embodiment of the present application includes a first limiting plate 410 and a second limiting plate 420 connected to each other, and the first limiting plate 410 and the second limiting plate 420 are arranged at an angle; one end of the first limiting plate 410 away from the second limiting plate 420 and one end of the second limiting plate 420 away from the first limiting plate 410 are respectively connected to the first side wall 111 of the mounting groove 110; the first limiting plate 410 and the second side wall 112 of the mounting groove 110 can form an installation space 113, and when the clamping member 300 is in the clamping position, the clamping member 300 can be at least partially clamped into the installation space 113; wherein the first side wall 111 and the second side wall 112 are arranged relatively to each other. By clamping the clamping member 300 in the installation space 113, the second side wall 112 of the installation groove 110 and the first limiting plate 410 respectively limit the two sides of the clamping member 300, so as to prevent the clamping member 300 from moving in the installation groove 110 and detaching from the installation groove 110. In one specific embodiment, the angle between the first limiting plate 410 and the second limiting plate 420 is 120°. Of course, in other embodiments, the angle between the first limiting plate 410 and the second limiting plate 420 can also be 90°, 130° or 150°, etc., and there is no special limitation on this. It only needs to satisfy that the installation space 113 formed by the first limiting plate 410 and the second side wall 112 is a gradually narrowing structure from the bottom of the installation groove 110 toward the opening side, so that the clamping member 300 is not easy to detach from the installation space 113 when clamped in the installation space 113.

[0062] In one embodiment, the limiting member 400 is an elastic member. The elastic deformation capability of the elastic member itself makes it easier to separate the clamping member 300 from the mounting groove 110. Specifically, the limiting member 400 can be made of a leaf spring.

[0063] In one of the embodiments, the clamping member 300 also has an unlocking position relative to the body 100. When the clamping member 300 is in the unlocking position, all parts of the clamping member 300 are located outside the mounting groove 110. When the clamping member 300 rotates around the rotation axis of the first rotating shaft 210, it can rotate from the unlocking position to the clamping position. When it is necessary to install the first actuator 200 on the body 100, at this time, one end of the planetary gear set is first connected to the power output end of the driving member, and the clamping member 300 is rotated so that the clamping member 300 rotates around the rotation axis of the first rotating shaft 210, so that the clamping member 300 at least partially extends into the mounting space 113, thereby allowing the clamping member 300 to be moved from the mounting groove 113 to the mounting groove 113. Figure 3 The unlocked position shown is rotated to the latched position, and the installation of the first actuator 200 is completed.

[0064] See also Figure 3The installation groove 110 of the cleaning mechanism provided in one embodiment of the present application is gradually expanded from the bottom of the groove toward the opening. By setting the installation groove 110 as a gradually expanded structure from the bottom of the groove toward the opening, the clamping member 300 can more conveniently enter the installation groove 110 when rotating around the rotation axis of the first rotation shaft 210.

[0065] See also Figure 7 and Fig. 9 , the planetary gear set of the cleaning mechanism provided in one embodiment of the present application includes a first planetary gear set 231 and a second planetary gear set 232 which is transmission-connected to the first planetary gear set 231; the first planetary gear set 231 and the second planetary gear set 232 are both contained in the inner gear ring 233, the first planetary gear set 231 is detachably connected to the power output end of the driving member, and the second planetary gear set 232 is transmission-connected to the first rotating shaft 210. Since the planetary gear set includes a two-stage planetary gear transmission assembly, the rotation speed output by the driving member can be greatly reduced, thereby meeting the rotation speed requirement of the first actuator 220, that is, the leaf sweeping brush. In one specific embodiment, the rotation speed output by the driving member is 4000 revolutions per second, and the rotation speed finally output to the first rotating shaft 210 through the second planetary gear set 232 is 250 revolutions per second.

[0066] See also Figure 7 and Fig. 9The first planetary gear set 231 of the cleaning mechanism provided in one embodiment of the present application includes a first sun gear 2311, a plurality of first planetary gears 2312 and a first planet carrier 2313 that cooperate with each other; the first sun gear 2311 is at least partially accommodated in the inner gear ring 233, and the first sun gear 2311 is detachably connected to the power output end of the driving member; the plurality of first planetary gears 2312 are respectively mounted on the first planet carrier 2313, and the plurality of first planetary gears 2312 are arranged at intervals along the circumference of the first sun gear 2311 and mesh with the first sun gear 2311 for transmission, and the plurality of first planetary gears 2312 are arranged at intervals along the circumference of the first sun gear 2311 and mesh with the first sun gear 2311 for transmission, and the plurality of The first planetary gears 2312 are arranged in the inner ring gear 233 and mesh with the inner ring gear 233. Specifically, the installation cavity of the inner ring gear 233 has internal teeth 2331, and the internal teeth 2331 mesh with the teeth of the first planetary gears 2312; when the first sun gear 2311 rotates around its own rotation axis, it can drive multiple first planetary gears 2312 to rotate around their own rotation axes and around the axis of the first sun gear 2311, so as to drive the first planetary carrier 2313 to rotate around its own rotation axis; the first planetary carrier 2313 is transmission connected to the second planetary gear set 232. When the first actuator 200 needs to perform a fallen leaf cleaning operation, the driving member drives the first sun gear 2311 to rotate around its own rotation axis, and then the first sun gear 2311 drives the first planetary gear 2312 to rotate around its own rotation axis, and the inner ring 233 does not rotate. The first planetary gear 2312 drives the first planetary carrier 2313 to rotate around its own rotation axis, thereby transmitting the power of the first planetary gear set 231 to the second planetary gear set 232.

[0067] Specifically, a first mounting column 23131 is provided on the first planet carrier 2313 , and the first planetary gear 2312 is sleeved on and fixedly connected to the first mounting column 23131 .

[0068] It needs to be explained again that since the inner ring gear 233 and the clamping part 300 are fixed relative to the body 100, the inner ring gear 233 will not rotate when the first sun gear 2311 rotates, thereby effectively avoiding the transmission failure in which the first sun gear 2311 drives the inner ring gear 233 to rotate while the first planetary gears 2312 and the first planetary carrier 2313 do not rotate.

[0069] In one specific embodiment, the number of the first planetary gears 2312 is three, and the three first planetary gears 2312 are arranged at intervals along the circumference of the first sun gear 2311. In another specific embodiment, the number of the first planetary gears 2312 is four, and the four first planetary gears 2312 are arranged at intervals along the circumference of the first sun gear 2311. It should be noted that there is no special limitation on the number of the first planetary gears 2312, which can be adaptively increased or decreased according to the number of teeth of the first planetary gears 2312 and the first sun gear 2311 and the required speed ratio.

[0070] See also Figure 7 and Fig. 9 The speed change group 230 of the cleaning mechanism provided in one embodiment of the present application also includes an input shaft 234, one end of the input shaft 234 is connected to the power output end of the driving member, and the first sun gear 2311 is sleeved and fixedly connected to the other end of the input shaft 234, and then the power of the driving member is transmitted to the first sun gear 2311 through the input shaft 234.

[0071] In one embodiment, the speed ratio of the first sun gear 2311 to the first planetary carrier 2313 is 3:1-4:1. By setting the speed ratio of the first sun gear 2311 to the first planetary carrier 2313 to be within the range of 3:1 to 4:1, the speed output by the driving member can be effectively reduced to better meet the lower speed requirement of the first actuator 220, that is, the leaf brush. In one specific embodiment, the speed ratio of the first sun gear 2311 to the first planetary carrier 2313 is 4:1, and in another specific embodiment, the speed ratio of the first sun gear 2311 to the first planetary carrier 2313 is 3:1. In another specific embodiment, the speed ratio of the first sun gear 2311 to the first planetary carrier 2313 is 3.5:1.

[0072] See also Figure 7 and Fig. 9The second planetary gear set 232 of the cleaning mechanism provided in one embodiment of the present application includes a second sun gear 2321, a plurality of second planetary gears 2322 and a second planet carrier 2323; the second sun gear 2321 is sleeved and fixedly connected to the side of the first planet carrier 2313 away from the first planetary gear 2312; the plurality of second planetary gears 2322 are respectively installed on the second planet carrier 2323, the plurality of second planetary gears 2322 are arranged at intervals along the circumference of the second sun gear 2321 and mesh with the second sun gear 2321 for transmission, and the plurality of second planetary gears 2322 is arranged in the inner ring gear 233 and meshes with the inner ring gear 233. Specifically, the inner teeth 2331 of the inner ring gear 233 mesh with the teeth of the second planetary gear 2322; when the second sun gear 2321 rotates around its own rotation axis, it can drive multiple second planetary gears 2322 to rotate around their own rotation axes and around the axis of the second sun gear 2321, so as to drive the second planetary carrier 2323 to rotate around its own rotation axis; the second planetary carrier 2323 is fixedly connected to the first rotating shaft 210 on the side away from the second planetary gear 2322. When the first actuator 200 is performing a fallen leaf cleaning operation, when the power of the first planetary gear set 231 is transmitted to the second sun gear 2321 via the first planetary carrier 2313, the second sun gear 2321 rotates around its own rotation axis, and then the second sun gear 2321 drives the second planetary gear 2322 to rotate around its own rotation axis and around the axis of the second sun gear 2321, and the second planetary gear 2322 drives the second planetary carrier 2323 to rotate around its own rotation axis, thereby transmitting the power of the second planetary gear set 232 to the first rotating shaft 210.

[0073] It should be noted that the present application reduces the rotational speed output from the power output end of the driving member by selecting two sets of planetary gear sets arranged axially along the first actuator component 200. Compared with other reduction structures (such as belt drives, gear reducers, etc.), the two sets of planetary gear sets arranged axially along the first actuator component 200 require less space, making the entire first actuator component 200 smaller in size, lighter in weight, simpler in structure, and easier to manufacture. At the same time, the transmission efficiency is also higher, reaching 97%-99%, with better economic benefits.

[0074] In one specific embodiment, the number of the second planetary gears 2322 is three, and the three second planetary gears 2322 are arranged at intervals along the circumference of the first sun gear 2311. In another specific embodiment, the number of the second planetary gears 2322 is four, and the four second planetary gears 2322 are arranged at intervals along the circumference of the second sun gear 2321. It should be noted that there is no special limitation on the number of the second planetary gears 2322, which can be adaptively increased or decreased according to the number of teeth of the second planetary gears 2322 and the second sun gear 2321 and the required speed ratio.

[0075] Specifically, the second planet carrier 2323 is provided with a second mounting column 23231 , and the second planetary gear 2322 is sleeved on and fixedly connected to the second mounting column 23231 .

[0076] See also Figure 7 and Fig. 9 , the speed ratio of the second sun gear 2321 of the cleaning mechanism provided in one embodiment of the present application to the speed ratio of the second planetary carrier 2323 is 3:1-4:1. By setting the speed ratio of the second sun gear 2321 to the speed ratio of the second planetary carrier 2323 to the range between 3:1 and 4:1, the speed output of the driving member can be effectively reduced under the transmission action of the first planetary gear set 231 and the second planetary gear set 232, so as to better meet the lower speed requirement of the first actuator 220, that is, the leaf sweeping brush. In one specific embodiment, the speed ratio of the second sun gear 2321 to the speed ratio of the second planetary carrier 2323 is 4:1, and in another specific embodiment, the speed ratio of the second sun gear 2321 to the speed ratio of the second planetary carrier 2323 is 3:1. In another specific embodiment, the speed ratio of the second sun gear 2321 to the speed ratio of the second planetary carrier 2323 is 3.5:1.

[0077] See also Figure 7 and Fig. 9 The speed change group 230 of the cleaning mechanism provided in one embodiment of the present application further includes an anti-wear pad 235, which is abutted between the clamping member 300 and the inner gear ring 233 along the axial direction of the first rotating shaft 210. By providing the anti-wear pad 235 between the clamping member 300 and the inner gear ring 233, the ends of the clamping member 300 and the inner gear ring 233 are better protected, so that the ends of the clamping member 300 and the inner gear ring 233 adjacent to each other are not easily worn.

[0078] See also Figure 8 , Figure 8 Shows Figure 1 The schematic diagram of the clamping member 300 of the cleaning mechanism is shown. In one embodiment, the clamping member 300 is a handle.

[0079] Specifically, the clamping member 300 includes a disc portion 320 covering the opening of the inner gear ring 233 on one side facing the driving member, an extension portion 330 extending radially outward from the disc portion 320, and a handle portion 340 extending from the extension portion 330 in a direction perpendicular to the extension portion 330 in a direction away from the first actuator 200. When the clamping member 300 is in the clamping position, the handle portion 340 enters the installation space 113. When the first actuator 200 is working, the first actuator 200 rotates around its own axis, and the limit member 400 prevents the handle portion 340 from rotating outside the installation space 113, thereby preventing the inner gear ring 233 from being driven by the first planetary gear set to rotate.

[0080] Since the clamping member 300 is provided with a handle portion 340 , after the first actuator 200 is detached from the body 100 , the user can move the first actuator 200 away by holding the handle portion 340 of the clamping member 300 .

[0081] In one specific embodiment, the cavity wall of the installation cavity 221 is loosely matched with the outer wall of the gear shift group 230. When the first actuator 220 needs to be replaced after a long period of use, since the cavity wall of the installation cavity 221 will not contact the outer wall of the gear shift group 230, a friction force will not be applied to the cavity wall of the installation cavity 221, so that the first actuator 220 to be replaced can be separated from the outer periphery of the first rotating shaft 210 more conveniently.

[0082] In one embodiment, the cleaning mechanism further includes a second actuator, which includes a second rotating shaft and a second actuator; the second actuator is fixedly mounted on the second rotating shaft, and the second rotating shaft is detachably connected to the power output end of the driving member, and the driving member can drive the second rotating shaft to rotate around its own rotation axis. By providing the second actuator, the cleaning mechanism can achieve multifunctional cleaning operations. For example, when the first actuator 200 is a leaf sweeping assembly, the second actuator can be a soil loosening blade assembly, so that the cleaning mechanism described in the present application can perform both leaf sweeping operations and soil loosening operations. In another specific embodiment, the second actuator can also be a grass combing assembly, so that the cleaning mechanism described in the present application can perform both leaf sweeping operations and grass combing operations.

[0083] In one embodiment, the rotation speed of the second rotating shaft is different from the rotation speed of the first rotating shaft 210. By setting the rotation speed of the second rotating shaft to be different from the rotation speed of the first rotating shaft 210, the cleaning mechanism 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 rotating shaft 210 is 250 revolutions per second, and the rotation speed of the second rotating shaft is 4000 revolutions per second.

[0084] In one embodiment, the cleaning mechanism further includes a third actuator, which includes a third rotating shaft and a third actuator; the third actuator is fixedly mounted on the third rotating shaft, and the third rotating shaft is detachably connected to the power output end of the driving member, and the driving member can drive the third rotating shaft to rotate around its own rotation axis. Optionally, when the second actuator is a loosening blade assembly, the third actuator is a grass combing assembly. And when the second actuator is a grass combing assembly, the third actuator is a loosening blade assembly.

[0085] When the garden is taken care of by the above-mentioned cleaning mechanism, the first actuator 200, the second actuator and the third actuator 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 comb the grass in the garden, the third actuator is a grass combing brush, and the third actuator is connected to the power output end of the driver, so that the grass combing operation is performed by the third actuator. When the grass combing operation is completed, it is necessary to perform a leaf sweeping operation, and the third actuator is detached from the driver, and the first actuator 200 is connected to the power output end of the driver, and the first actuator 220 is a leaf sweeping brush, so that the leaf sweeping operation is performed by the first actuator 220. When the leaf sweeping operation is completed, it is necessary to perform a loosening operation, then the first actuator 200 is replaced with the second actuator, the second actuator is connected to the power output end of the driver, and the second actuator is a loosening blade, and then the garden is loosened.

[0086] 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.

[0087] 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.

[0088] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
