[0073] Please refer to Figures 1 to 13. The garden tool of the present invention integrates various functions of the body 002 by rationally planning the structure of the body 002, making the body 002 smaller in size, lighter in weight, and having fewer parts, thereby reducing production costs and rationally utilizing the oil in the oil storage chamber 110 to cool the drive assembly 500, thereby increasing the continuity of the operation of the body 002.

[0074] Please refer to Figure 1, which is a schematic diagram of the overall structure of an embodiment of the garden tool of the present invention. The present invention provides a garden tool, which includes: a connecting rod assembly 001, a body 002, and a sawing assembly 003. The body 002 is mounted on one end of the connecting rod assembly 001. By holding the end of the connecting rod assembly 001 away from the body 002, the operator can control the body 002 to work at a certain height. The end of the connecting rod assembly 001 away from the body 002 can also be provided with a control device 004 for convenient control of the body 002 and an energy device for supplying energy to the control device 004 and the body 002. In order to reduce the weight of the garden tool and facilitate hand-held operation by the operator, the energy device can be operated separately from the control device 004.

[0075] Please refer to Figures 2, 12, and 13. Figure 2 is a schematic diagram of the structure of the housing of one embodiment of the garden tool of the present invention. Figure 12 is a cross-sectional view of the internal structure of the housing of another embodiment of the garden tool of the present invention. Figure 13 is a schematic diagram illustrating the relative positions of the various chambers of another embodiment of the garden tool of the present invention. The housing 002 comprises a housing 020, a drive assembly 500, and an oil supply assembly 600. Within the housing 020 are adjacently provided an oil reservoir 110 and a drive assembly mounting slot 120. The drive assembly 500 is fixedly mounted within the drive assembly mounting slot 120. The oil reservoir 110 is used to store oil for lubricating the sawing assembly 003. The integration of the oil reservoir 110 and the drive assembly 500 within the housing 020 of the housing 002 not only makes the garden tool more compact but also eliminates the need for a separate oil storage device, reducing the overall weight of the tool. Furthermore, because the oil reservoir 110 and the drive assembly mounting slot 120 are positioned adjacent to each other, the lubricating oil in the oil reservoir 110 also provides a certain heat dissipation effect for the drive assembly 500.

[0076] Please refer to Figures 3 and 4. Figure 3 is a front view of the first housing in an embodiment of the garden tool of the present invention, and Figure 4 is a rear view of the first housing in an embodiment of the garden tool of the present invention. The oil supply assembly 600 is mounted on the housing 020, and the oil inlet 610 of the oil supply assembly 600 is connected to the oil storage chamber 110. The oil outlet 620 of the oil supply assembly 600 is located outside the housing 020. Driven by the drive assembly 500, the oil supply assembly 600 draws lubricating oil from the oil storage chamber 110 to the sawing assembly to be lubricated. In this embodiment, the oil supply assembly 600 is an oil pump, and the oil in the oil storage chamber 110 flows through the oil pump to the sawing assembly 003, replacing the traditional oil supply pipeline, simplifying the internal design of the body 002, and making the structure more compact. The saw assembly 003 is fixedly mounted on one side of the oil outlet 620 of the housing 020 and includes a rotatable cutting blade. The cutting blade is mounted on the drive shaft of the drive assembly 500 and is driven by the drive assembly 500 to perform the cutting operation. The drive assembly 500 includes, but is not limited to, a fuel engine and a drive motor. The drive assembly 500 also simultaneously drives the oil supply assembly 600 to supply oil to the saw assembly 003. It should be noted that structures and connection methods not specifically described in this application are prior art and can be obtained through common commercial means, and will not be further described here.

[0077] Referring to Figures 1 to 4 , in one example of the garden tool of the present invention, the housing 020 comprises a first housing 100, a second housing 200, and a third housing 300 assembled together. The first housing 100, the second housing 200, and the third housing 300 together form an oil reservoir 110 and a drive assembly mounting slot 120. The materials of the first housing 100, the second housing 200, and the third housing 300 are not limited. In this embodiment, the first housing 100, the second housing 200, and the third housing 300 are all made of aluminum, which provides a balance between lightness and strength. The drive assembly mounting slot 120 is provided on the first housing 100. The oil supply assembly 600 is mounted on the housing 020. The second housing 200 engages with the first housing 100 to form the oil reservoir 110. In this way, a part of the first shell is used as the oil storage chamber 110, and there is no need to install a separate oil pot, which simplifies the structure of the body 002. At the same time, the lubricating oil in the oil storage chamber 110 is in direct contact with the first shell 100, which is beneficial for dissipating heat for the drive assembly 500 installed in the drive assembly mounting groove 120. The first shell 100 is provided with a fixing portion 150 for fixing the body 002 on the connecting rod assembly 001. In the present application, the drive assembly 500, the oil storage chamber 110 and the oil supply assembly 600 are integrated and installed on the first shell 100. At the same time, the first shell 100 is fixedly connected to the connecting rod assembly 001 and the sawing assembly 003 is fixed to the first shell 100. In this way, with the first shell 100 as the main body, multiple components are integrated and installed, which can effectively reduce the weight of the entire equipment. In addition, the lubricating oil in the oil storage chamber also has the effect of dissipating heat for the sawing assembly 003.

[0078] Referring to Figures 1 to 4 , a sealing gasket is positioned between the first housing 100 and the second housing 200 to ensure the tightness of the oil reservoir 110. The sealing gasket is equipped with a foolproof structure to prevent reverse installation during assembly. The third housing 300 snaps into place in the corresponding area of ​​the drive assembly mounting slot 120 on the side of the first housing 100 away from the second housing 200, forming a drive chamber 330 with the first housing 100. A hook 160 is provided on the side of the first housing 100. When placing the garden tool, the hook 160 can be hung on a branch or other location to prevent it from tipping over, potentially damaging the garden tool or causing safety hazards. The third housing 300 and the bottom wall of the drive assembly mounting slot 120 together form the drive chamber 330. One end of the oil pump's rotating shaft 630 is located within the drive chamber 330. The output shaft 510 of the drive assembly 500 extends into the drive chamber 330 and is rotatably connected to the oil pump's rotating shaft 630, thereby driving the oil pump's rotation and providing oil lubrication for the saw assembly 003. The oil pump is directly press-fitted onto the first housing 100 and cooperates with the oil inlet 610 and the oil outlet 620, so that the lubricating oil enters the oil inlet 610 from the oil storage chamber 110, and then flows out from the oil outlet 620 to the part to be lubricated of the sawing assembly 003. In this way, there is no need for additional fixation of the oil pump, which simplifies the structure of the entire body 002 and ensures the stability of the oil pump. The oil outlet 620 is directly opened on the first housing 100, eliminating the use of the traditional oil outlet pipe, and further simplifying the structure of the body 002. A number of ventilation holes 121 are also provided on the bottom wall of the drive assembly mounting groove 120, and the shape of the ventilation holes 121 is not limited. The airflow enters the drive assembly mounting groove 120 through the ventilation holes 121 and carries the heat of the drive assembly 500 out through the air guide window 410.

[0079] Please refer to Figures 3 and 4. In an example of the garden tool of the present invention, the oil supply assembly 600 includes an oil inlet 610 and an oil outlet 620. The oil inlet 610 and the oil outlet 620 are integrally formed with the first shell 100, and the oil inlet 610 is connected to the oil outlet 620. The oil inlet 610 is located in the oil storage chamber 110, and the oil outlet 620 is located on the outside of the first shell 100. The oil pump is located in the connecting channel between the oil inlet 610 and the oil outlet 620. The oil pump controls the lubricating oil in the oil storage chamber 110 to flow through the oil inlet 610 and the oil outlet 620 to the part to be lubricated of the sawing assembly 003.

[0080] Please refer to Figures 1, 2, 6, and 7. Figure 6 is a schematic diagram of the structure of the drive assembly in one embodiment of the garden tool of the present invention, and Figure 7 is a schematic diagram of the connection between the drive assembly and the oil supply assembly in one embodiment of the garden tool of the present invention. In this example of the garden tool of the present invention, the drive assembly 500 includes a drive motor. Drive motors are more environmentally friendly and have lower energy consumption than fuel engines. The first end 511 of the output shaft 510 of the drive motor passes through the bottom wall of the drive assembly mounting slot 120 and the third housing 300. The portion of the first end 511 located within the drive cavity 330 of the third housing 300 is rotatably connected to the oil supply assembly 600. The rotating shaft 630 of the oil pump and the output shaft 510 of the drive motor are engaged by gears to achieve power transmission through the rotational connection. The gear engagement method is not limited. In this embodiment, a worm gear 631 is provided at the end of the rotating shaft 630 of the oil pump, and a worm 513 (as shown in Figure 7) is provided on the output shaft 510 of the drive assembly 500 to mesh with the worm gear 631. The end portion of the first end 511 located outside the third housing 300 is rotatably connected to the sawing assembly 003 to realize the cutting function of the sawing assembly 003 .

[0081] Please refer to Figures 2, 9, and 12. Figure 9 is a schematic diagram of the structure of the third housing in an embodiment of the gardening tool of the present invention. In this embodiment of the gardening tool of the present invention, the third housing 300 is provided with an output hole 310, through which the output shaft 510 passes. During gardening operations, sawing debris from the sawing assembly 003 can easily be drawn into the output hole 310 and enter the interior of the housing 020, potentially causing equipment failure. Therefore, a dustproof assembly is provided in the gap between the output hole 310 and the output shaft 310. The dustproof assembly includes a dustproof pad 321, which cooperates with the output shaft 510 to prevent debris and other debris from remaining outside the housing. In this embodiment, a mounting seat is provided at the end of the output hole 310 near the drive chamber 330. The dustproof pad 321 is mounted on the mounting seat to facilitate replacement of the dustproof pad 321. The mounting base includes a plurality of fixing teeth 320, which are divided into two groups. The fixing teeth 320 of each group are distributed along the circumference of the dustproof pad 321. The two groups of fixing teeth 320 act on the two axial end surfaces of the dustproof pad 321, thereby securing the dustproof pad. Furthermore, the housing 020 of this embodiment is cast. To facilitate demolding, the two groups of fixing teeth 320 are staggered in the axial direction of the output hole, thus facilitating mold removal in the area between the two groups of fixing teeth 320.

[0082] Referring to Figures 2 and 4 , in one example of the garden tool of the present invention, a removable air scoop 400 is provided on the first housing 100. The drive assembly mounting slot 120 has an opening for removing and installing the drive assembly 500. The air scoop 400 snaps into the opening of the drive assembly mounting slot 120 to protect the cooling fan blades 520. The air scoop 400 is removable and replaceable to accommodate drive assemblies 500 of varying specifications. Air guide windows 410 are provided on the air scoop 400. The shape, size, and number of the air guide windows 410 are not limited, but must match the airflow of the cooling fan blades 520.

[0083] Please refer to Figure 6. In an example of the garden tool of the present invention, a heat dissipation fan blade 520 is provided on the second end 512 of the output shaft 510. The heat dissipation fan blade 520 rotates with the output shaft 510, so that the heat generated by the drive motor is promptly removed, thereby avoiding the frequent triggering of high-temperature protection of the drive motor. The type of heat dissipation fan blade 520 is not limited. It can be a straight-blowing type (the air inlet direction is parallel to the blowing direction) or a side-blowing type (the air inlet direction is perpendicular to the blowing direction). In this embodiment, the side-blowing type heat dissipation fan blade 520 is more suitable for exhausting air, and the wind pressure is greater than that of the straight-blowing type, resulting in a better heat dissipation effect.

[0084] Please refer to Figures 2 and 10. Figure 10 is a schematic diagram of the structure of the air scoop in one embodiment of the garden tool of the present invention. In this example of the garden tool of the present invention, the air scoop window 410 is located circumferentially of the heat dissipation blades 520. The air scoop window 410 is located in the blowing direction of the heat dissipation blades 520, allowing the airflow blown by the heat dissipation blades 520 to be directly discharged from the interior of the housing 020 through the air scoop window 410. In this embodiment, the air scoop 400 is a progressively opening air scoop (as shown in Figure 10). The progressively opening air scoop is provided with an air scoop window 410. The wall of the progressively opening air scoop confines the airflow to the air scoop window 410 for discharge. By selecting the progressively opening air scoop with air scoop windows 410 with different opening directions relative to the installation position, the direction of the air discharged from the air scoop window 410 can be adjusted to avoid the operator, thereby preventing the hot air flow from being blown towards the operator or the debris from being swept towards the operator. Furthermore, the air duct cross-section of the progressively opening air guide window 410 increases as it approaches the outside area, resulting in faster cooling and improved heat dissipation. Please refer to Figure 11, which is a schematic diagram of the structure of the air guide cover in another embodiment of the garden tool of the present invention. In another embodiment, multiple air guide windows 410 are provided, and the air outlets of the multiple air guide windows 410 are parallel to the rotation plane of the heat dissipation fan blades 520. This also improves heat dissipation, has a simple structure, and is relatively inexpensive to manufacture.

[0085] Please refer to Figures 3, 5, and 12. Figure 5 is an enlarged view of area A in Figure 1, and Figure 12 is a schematic diagram illustrating the relative positions of the various chambers in another embodiment of the garden tool of the present invention. In this example of the garden tool of the present invention, an air inlet chamber 130 is further provided within the first housing 100. The air inlet chamber 130 is located on the side of the drive assembly mounting slot 120 away from the oil storage chamber 110. The air inlet chamber 130 communicates with the drive assembly mounting slot 120 through the drive chamber 330. A first air inlet 140 is provided on the wall of the air inlet chamber 130 away from the drive chamber 330. The air inlet chamber 130, the drive chamber 330, and the drive assembly mounting slot 120 form a gas flow channel. Gas enters the gas flow channel through the first air inlet 140 and, under the action of the heat dissipation fan blades 520, removes heat from the drive assembly 500 through the air guide window 410.

[0086] Referring to Figures 1 and 5 , in one example of the garden tool of the present invention, one end of the connecting rod assembly 001 is fixed to the first housing 100. The connecting rod assembly 001 includes a telescopic rod whose length can be adjusted to suit different working heights. A hollow rod cavity is defined within the telescopic rod, communicating with the air inlet cavity 130. A second air inlet 010 is provided on the sidewall of the telescopic rod. Even if the first air inlet 140 is blocked, the second air inlet 010 ensures that sufficient air can enter the body 002 to assist in heat dissipation. The rod cavity also serves as a connection for the body 002, the sawing assembly 003, and the control device 004.

[0087] Please refer to Figure 8, which shows a schematic diagram of the installed protective cover in an embodiment of the garden tool according to the present invention. In this example of the garden tool according to the present invention, a protective cover 700 is provided at the connection between the saw assembly 003 and the body 002. A guide plate 710 is provided on the protective cover 700. The guide plate 710 is located at the edge of the protective cover 700 facing the fixed portion 150, and the guide plate 710 has an arc shape that matches the edge of the protective cover 700 facing the fixed portion. During the sawing process, debris is thrown along the circumferential direction of the saw assembly 600 as it rotates. The guide plate 710 is used to prevent the sawing debris from rolling toward the operator, directing the scattered sawing debris away from the operator.

[0088] Referring to Figure 2 , in one example of the garden tool of the present invention, the second housing 200 is provided with an oil cap 210 and a viewing window (not shown). Oiling the oil reservoir 110 through the oil cap 210 eliminates the need for connecting oil pipelines and increases the flexibility of the device. The viewing window is transparent, making it easy to observe the oil level in the oil reservoir 110.
