DETAILED DESCRIPTION

[0044] The following is combined with Figure 1-9 This application is described in further detail.

[0045] The embodiment of the present application discloses a multifunctional garden cleaning machine.

[0046] Reference Figure 1 A multifunctional garden cleaning machine includes a housing 1 and functional components mounted on the sidewalls of the housing 1. There are at least two functional components. In this embodiment, the functional components are a trimming component 2, a seam sweeping component 3, and a cleaning component 4.

[0047] Reference Figure 1 and Figure 2The housing 1 is provided with a handle 11 for a user to hold, a driving mechanism 12 for driving the functional component to move, a transmission mechanism 13 connected to the driving mechanism 12, and a locking mechanism 14 for locking the functional component.

[0048] The handle 11 is vertically inserted and mounted on the top of the housing 1. The drive mechanism 12 comprises a drive motor 121 bolted to the housing 1, a reducer 122 connected to the output shaft of the drive motor 121, and a drive shaft 123 for transmission connection to the transmission mechanism 13. The drive motor 121 is arranged vertically with the output shaft pointing downward. The drive shaft 123 is also provided with a rotary bearing for support at the end away from the reducer 122.

[0049] The transmission mechanism 13 is located on one side of the driving shaft 123 in the horizontal direction. The transmission mechanism 13 includes a transmission shaft 131 connected to the driving shaft 123 and a female connector 132 provided at the end of the transmission shaft 131 and used for plugging in the functional component. The transmission shaft 131 is arranged horizontally, that is, the extension direction of the transmission shaft 131 is perpendicular to the extension direction of the driving shaft 123, and the transmission shaft 131 and the driving shaft 123 are connected by a bevel gear set 15. The transmission shaft 131 is provided with a rotating bearing for support between the bevel gear set 15 and the female connector 132. The female connector 132 and the transmission shaft 131 are fixedly plugged in, and when the transmission shaft 131 rotates, it can drive the female connector 132 to rotate synchronously. Among them, the opposite side walls of the casing 1 have installation openings 16 for plugging the female connector 132 into the functional component.

[0050] Combine Figure 3 Each functional component has a male connector 21 that plugs into and mates with a female connector 132, and a fixed connector 22 that is inserted into the mounting opening 16 and fixedly connected to the housing 1. The end surface of the female connector 132 defines a slot 1321 for inserting the male connector 21, and a first transmission gear ring 1322 is circumferentially disposed along the sidewall of the slot 1321. The sidewall of the male connector 21 has a second transmission gear ring 211 that meshes with the first transmission gear ring 1322.

[0051] A fixed toothed ring 221 is integrally formed around the outer wall of the fixed connector 22. The housing 1 has fixed teeth 161 on both sides of the inner wall of the mounting opening 16 that mesh with the fixed toothed ring 221. When the fixed connector 22 of the functional assembly is inserted into the mounting opening 16, it engages with the fixed teeth 161 to secure it to the housing 1. The locking mechanism 14 on the housing 1 then locks the fixed connector 22 in place.

[0052] Reference Figure 3 and Figure 4The locking mechanism 14 comprises a fixed toothed ring 141 rotatably mounted on the inner wall of the mounting opening 16, a handle portion 142 integrally disposed on the outer side of the fixed toothed ring 141 and extending to the outside of the top of the housing 1, and a locking compression spring 143. The fixed toothed ring 141 is located on the side of the fixed toothed portion 161 away from the drive mechanism 12. The inner wall of the fixed toothed ring 141 has a limiting toothed ring 1411 that meshes with the fixed toothed ring 221. The top of the housing 1 has a rotational gap 17 that allows the handle portion 142 to rotate along its axis. The rotational gap 17 is adapted to the amount of compression of the locking compression spring 143.

[0053] The housing 1 has an installation chamber 18 for arranging a locking compression spring 143. One end of the locking compression spring 143 abuts against the bottom wall of the installation chamber 18, and the other end abuts against the side wall of the push handle 142. When the locking compression spring 143 is not compressed, the limiting gear ring 1411 and the fixed tooth portion 161 are in an interlaced state. Before inserting the fixed connector 22, the push handle 142 is first pushed so that the projections of the limiting gear ring 1411 and the fixed tooth portion 161 on the axis coincide with each other, and then the fixed connector 22 is inserted to engage with the fixed tooth portion 161. After that, the force applied by the push handle 142 is released, so that the fixed gear ring 141 is reset to a state interlaced with the fixed tooth portion 161 under the action of the locking compression spring 143, that is, the limiting gear ring 1411 can play a locking and limiting effect on the axial direction of the fixed gear ring 221.

[0054] Reference Figure 1 and Figure 3 The trimming assembly 2 is used for lawn edge trimming and maintenance operations. The trimming assembly 2 includes a trimming shield 23, a trimming shaft 24 rotatably mounted on the trimming shield 23, a trimming blade 25 fixedly mounted at the end of the trimming shaft 24, a male connector 21 fixedly connected to the end of the trimming shaft 24 away from the trimming blade 25, and a fixed connector 22 for fixed connection to the housing 1. The trimming shield 23 is an open semi-circular shell, and the trimming shaft 24 is coaxially arranged with the trimming shield 23. The trimming blade 25 is entirely located within the trimming shield 23, so that the trimming shield 23 can protect the end surfaces of the trimming blade 25. The trimming blade 25 is fixedly connected to the trimming shaft 24 via screws. A short roller brush 26 is also fixedly mounted on the trimming shaft 24. The short roller brush 26 is located within the trimming shield 23, and the outer diameter of the bristles of the short roller brush 26 is smaller than the outer diameter of the trimming blade 25.

[0055] according to Figures 1 to 4The male connector 21 is located outside the trimming shield 23 and is configured for transmission connection with the female connector 132. The fixed connector 22 is sleeved onto the outside of the male connector 21 and fixedly connected to the trimming shield 23 via screws. The male connector 21 of the trimming assembly 2 and the female connector 132 in the housing 1 are plugged and engaged, achieving a transmission connection between the transmission mechanism 13 and the trimming shaft 24. The fixed connector 22 is inserted into the mounting opening 16 and fixedly connected to the housing 1, thereby achieving a fixed connection between the housing 1 and the trimming shield 23. When the drive mechanism 12 is activated, the drive motor 121 drives the transmission mechanism 13 to rotate, which in turn drives the trimming shaft 24, which in turn drives the trimming blade 25 to rotate to trim the lawn.

[0056] Reference Figure 1 and Figure 5 The seam sweeping assembly 3 is used to clean the seams of the cleaning plate, the grass and moss on the corners and steps. The seam sweeping assembly 3 includes a seam sweeping shield 31, a seam sweeping rotating shaft 32 rotatably mounted on the seam sweeping shield 31, a seam sweeping brush disc 33 fixedly mounted on the end of the seam sweeping rotating shaft 32, a male connector 21 located at the end of the seam sweeping rotating shaft 32 away from the seam sweeping brush disc 33, and a fixed connector 22 for fixed connection to the casing 1. The seam sweeping shield 31 is also an open semi-disc shell as a whole, and the seam sweeping rotating shaft 32 is coaxially arranged with the seam sweeping shield 31. The seam sweeping brush disc 33 is located in the seam sweeping shield 31 as a whole, so that the seam sweeping shield 31 can protect the end faces of the seam sweeping brush disc 33 on both sides. The seam sweeping brush disc 33 is fixedly connected to the seam sweeping rotating shaft 32 by screws.

[0057] The male connector 21 is located outside the gap sweeping shield 31 and is rotatably connected to the gap sweeping shaft 32 via a universal joint 35. The universal joint 35 comprises a universal sleeve 351 mounted on the gap sweeping shaft 32 and a universal ball post 352 mounted on one end of the male connector 21 and mating with the universal sleeve 351. The arrangement of the universal joint 35 allows the male connector 21 and the gap sweeping shaft 32 to be tilted at a certain angle. Compared to cleaning with the gap sweeping shaft 32 horizontal to the ground, tilting the gap sweeping shaft 32 upward away from the ground allows the bristles of the gap sweeping brush disc 33 to more effectively clean the edges of the lawn and the gaps between the flat surface.

[0058] according to Figures 1 to 5The fixed connector 22 is sleeved onto the male connector 21 and fixedly connected to the sweeping shield 31 via screws. The male connector 21 of the sweeping assembly 3 engages with the female connector 132 in the housing 1, establishing a transmission connection between the transmission mechanism 13 and the sweeping shaft 32. The fixed connector 22 is inserted into the mounting opening 16 and fixedly connected to the housing 1, thereby establishing a fixed connection between the housing 1 and the sweeping shield 31. When the drive mechanism 12 is activated, the drive motor 121 drives the transmission mechanism 13 to rotate, which in turn drives the sweeping shaft 32 to rotate, which in turn drives the sweeping brush disc 33 to rotate to clean the lawn.

[0059] Reference Figure 1 When the housing 1 is installed with the trimming assembly 2 or the seam sweeping assembly 3, a support wheel assembly 5 for supporting the bottom surface is installed on the other side of the trimming assembly 2 and the seam sweeping assembly 3. The support wheel assembly 5 includes a support wheel 51, a support rotating shaft (not shown) rotatably mounted with the support wheel, and a fixed connector 22 provided on the support rotating shaft 52. The fixed connector 22 is rotatably mounted with the support rotating shaft. The fixing method of the support wheel assembly 5 and the housing 1 is the same as the fixing method of the functional assembly and the housing 1. The support wheel assembly 5 can improve the stability of the user when using the trimming assembly 2 or the seam sweeping assembly 3 for maintenance.

[0060] Reference Figure 1 and Figure 6 The cleaning assembly 4 is used to clean dirt, moss, and weeds from paved surfaces such as courtyards and driveways. The cleaning assembly 4 includes a cleaning shield 41 disposed at the bottom of the housing 1, a cleaning shaft 42 rotatably mounted on the cleaning shield 41, a cleaning roller brush 43 coaxially mounted on the cleaning shaft 42, a male connector 21 arranged parallel to the cleaning shaft 42, and a fixed connector 22 mounted outside the male connector 21 for fixed connection to the housing 1. The cleaning roller brush 43 is entirely located within the cleaning shield 41 and is fixedly connected to the cleaning shaft 42 via screws.

[0061] The male connector 21 of the cleaning assembly 4 and the cleaning rotating shaft 42 are connected by a gear transmission assembly 44 so that the male connector 21 and the cleaning rotating shaft 42 can be arranged in parallel and spaced apart. The cleaning assembly 4 also has a gear bracket 45 for mounting the gear transmission assembly 44, and the gear bracket 45 is fixedly connected to the cleaning shield 41 by screws.

[0062] according to Figures 1 to 6The male connector 21 of the cleaning assembly 4 is integrally formed with the gear bracket 45. The male connector 21 engages with the female connector 132 within the housing 1, and the gear transmission assembly 44 provides a transmission connection between the transmission mechanism 13 and the cleaning shaft 42. The fixed connector 22 is inserted into the mounting opening 16 and fixedly connected to the housing 1, thereby securing the housing 1 to the gear bracket 45. When the drive mechanism 12 is activated, the drive motor 121 rotates the transmission mechanism 13, which in turn rotates the cleaning shaft 42, which in turn rotates the cleaning roller brush 43 to clean the floor.

[0063] Reference Figure 7 The multifunctional garden cleaning machine of the present application further includes a disassembly and assembly device 6 for disassembling and assembling functional components. The disassembly and assembly device 6 includes a disassembly and assembly box 61 with an upper opening, a lifting seat 62 that is lifted and arranged in the disassembly and assembly box 61 and is used for fixing, a lifting assembly 63 that drives the lifting seat 62 to vertically lift and lower, a first feeding mechanism 64 for disassembling and assembling the cleaning component 4, a second feeding mechanism 65 for disassembling the trimming component 2, and a third feeding mechanism 66 for disassembling and assembling the seam sweeping component 3. The lifting seat 62 is also provided with a pushing mechanism 67 that pushes the push handle 142 to switch the locking mechanism 14 to the unlocked state.

[0064] The lifting seat 62 drives the lifting assembly 63 to rise and fall vertically, so that the lifting seat 62 has a detachment position, a first position, a second position, and a third position from top to bottom in the height direction. When the lifting seat 62 is in the detachment position, the lifting seat 62 is located outside the top of the disassembly box 61, used for fixing the housing 1 and the lifting seat 62; when the lifting seat 62 is in the first position, the height of the lifting seat 62 corresponds to the first feeding mechanism 64; when the lifting seat 62 is in the second position, the height of the lifting seat 62 corresponds to the second feeding mechanism 65; when the lifting seat 62 is in the third position, the height of the lifting seat 62 corresponds to the third feeding mechanism 66.

The lifting assembly 63 includes a horizontally arranged lifting motor 631, a steering box 632 connected to the output shaft of the lifting motor 631 for changing the direction of rotation, a connecting shaft 633 connecting the two sides of the steering box 632, and a screw elevator 634 connected to the connecting shaft 633 and for mounting the lifting columns 621. The disassembly and assembly box 61 contains mounting slots 611 for mounting the lifting motor 631, the steering box 632, and the screw elevator 634. The lifting base 62 is bolted to the top of the screw elevator 634. When the lifting motor 631 is activated, it transmits driving force to the steering box 632, which in turn transmits the driving force to the screw elevator 634 via the connecting shaft 633. The lifting and lowering of the screw elevator 634 causes the lifting columns 621 to rise and fall synchronously.

[0066] The same sidewalls of the two lifting posts 621 have a first recess (not shown), into which a first magnet 622 is fixedly mounted. The sidewalls of the housing 1 have a second recess, into which a second magnet 19 is fixedly mounted, designed to interact with the first magnet 622. The mutual attraction between the first magnet 622 and the second magnet 19 secures the housing 1 to the lifting base 62, allowing the lifting base 62 to move the housing 1 synchronously.

[0072] The second horizontal drive member 652 is a linear module driven by a motor, comprising a motor, a lead screw connected to the motor output shaft, a slide rail arranged along the length direction of the lead screw, and a slider for the lead screw thread to pass through and to slide with the slide rail. The second feed bracket 651 is bolted to the top of the slider. The extension direction of the lead screw is consistent with the installation direction of the trimming assembly 2 and the support wheel assembly 5. Two second feed columns 653 are horizontally slidably provided on the second feed bracket 651, and the two second feed columns 653 are spaced apart in the height direction. The trimming shield 23 and the support wheel 51 of the trimming assembly 2 both have a plug-in hole 231 for inserting the second feed column 653. The second disengagement drive member 654 is a cylinder, and the second disengagement drive member 654 can drive the two second feed columns 653 to move horizontally at the same time.

[0073] The third feeding mechanism 66 includes a third feeding bracket 661 symmetrically arranged on both sides of the lifting seat 62, a third horizontal driving member 662 for driving the third feeding bracket 661 to move horizontally, a third feeding column 663 arranged at the top of the third feeding bracket 661 and used to insert the seam sweeping assembly 3 and the support wheel assembly 5, and a third disengagement driving member 664 for driving the third feeding column 663 to disengage.

[0074] Reference Figure 5 、 Figure 7 and Figure 9The third horizontal drive member 662 is a linear module driven by a motor, including a motor, a lead screw connected to the output shaft of the motor, a slide rail arranged along the length direction of the lead screw, and a slider for the lead screw thread to pass through and slide with the slide rail. The third feeding bracket 661 is bolted to the top of the slider. The extension direction of the lead screw is consistent with the installation direction of the seam sweeping assembly 3. Two third feeding columns 663 are slidably mounted on the third feeding bracket 661, and the two third feeding columns 663 are arranged at intervals along the height direction. The side walls of the fixed connecting head 22 of the seam sweeping assembly 3 and the support wheel 51 both have a plug hole 231 for inserting the third feeding column 663. The third disengagement drive member 664 is a cylinder, and the third disengagement drive member 664 can drive the two third feeding columns 663 to move horizontally at the same time.

The support assembly moves horizontally toward the housing 1, allowing the fixed connector 22 to be inserted into the installation opening 16. After the fixed connector 22 engages with the fixed ring gear 221, the push handle 142 is reset to lock the locking mechanism 14. Finally, the third disengagement driver 664 disengages the third feed column 663 horizontally from the sweeping assembly 3 and the support wheel assembly 5 and returns it to its initial position. Simultaneously, the lifting base 62 rises to the disengagement position, and the user removes the housing 1 from the lifting base 62, completing the automatic installation of the housing 1 and the cleaning assembly 4. The removal and installation procedures for the cleaning assembly 4 are the reverse of the previous ones.
