[0001] This utility model relates to the field of garden tool technology, and in particular to a pruning machine. [Background Technology]

[0002] A pruning machine is a common gardening tool that includes a motor, pruning blades, and a gearbox connecting the motor and the pruning blades. The motor drives the pruning blades to reciprocate through the gearbox, thereby cutting various shrubs, hedges, etc.

[0003] Existing pruning machines have an opening in their housing, through which at least part of the switch trigger protrudes and is exposed outside the housing to facilitate user operation of starting and stopping the machine. However, since pruning machines are used in outdoor environments, when the user operates the switch trigger, dust, grass clippings, and other debris from the outdoor environment can enter the housing through the gap between the switch trigger and the opening, which can affect the normal operation of the pruning machine over time.

[0004] Therefore, it is indeed necessary to provide an improved pruning machine to overcome the shortcomings of the existing technology. [Utility Model Content]

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a pruning machine with good dust prevention effect.

[0007] Furthermore, the housing also includes a first receiving cavity located at least partially below the switch trigger, the first shielding member being disposed within the first receiving cavity, and the first receiving cavity communicating with the opening.

[0008] Furthermore, the housing also includes a chip discharge port disposed below the opening, the chip discharge port being in communication with the first receiving cavity.

[0009] Furthermore, the pruning machine also includes a cover plate that selectively closes the chip discharge port, the cover plate being rotatably connected to the outside of the housing.

[0010] Furthermore, in the height direction of the pruning machine, the cover plate is installed between the opening and the chip discharge port.

[0011] Furthermore, the opening direction of the chip discharge port is inclined downward.

[0012] Furthermore, the pruning machine also includes a second blocking member connected to or integrally formed with the switch trigger, the second blocking member being located above the first blocking member.

[0013] Furthermore, the second shielding member is located above the opening.

[0014] Furthermore, the housing also includes a second receiving cavity located at least partially above the switch trigger, the switch body being disposed within the second receiving cavity, the first receiving cavity being in fluid communication with the second receiving cavity, and the second blocking member being located at the connection between the first receiving cavity and the second receiving cavity.

[0015] Furthermore, the second blocking member extends at least partially from the switch trigger in the lateral direction.

[0016] Compared with the prior art, this utility model has the following beneficial effects: The pruning machine includes a housing, a switch body fixedly installed in the housing, and a switch trigger movably installed in the housing.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. In the description of this specification, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0034] The terminology used in this invention is for the purpose of describing specific embodiments only and is not intended to limit the invention. For example, terms such as "upper," "lower," "front," and "rear" that indicate orientation or positional relationship are based solely on the orientation or positional relationship shown in the accompanying drawings and are used only for the convenience of describing the invention and simplifying the description. They do not indicate or imply that the device / component referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the invention.

[0035] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0036] Please see Figures 1 to 5The pruning machine 100 shown is an embodiment of the present invention, including a housing 1, pruning blades 2, a transmission device (not shown), a motor (not shown) and a battery pack 3.

[0037] The housing 1 includes a main housing portion 11, a power housing portion 12, a grip portion 13, and a connecting portion 14. Specifically, the pruning blade 2 is supported by the main housing portion 11, with one end fixedly mounted to the main housing portion 11 and the other end extending forward from the main housing portion 11 out of the housing 1 for pruning operations; the power housing portion 12 is connected to or integrally formed with the rear of the main housing portion 11, the motor is supported by the power housing portion 12, and the motor and transmission device are at least partially housed inside the power housing portion 12, the transmission device is connected between the motor and the pruning blade 2, and the rotational motion of the motor is transmitted to the pruning blade 2 through the transmission device to drive the pruning blade 2 to move; the grip portion 13 is connected to or integrally formed with the rear of the power housing portion 12, the connecting portion 14 is connected to or integrally formed with the rear of the grip portion 13, and the battery pack 3 is used to power the pruning machine 100 and is detachably installed in the connecting portion 14.

[0038] The pruning machine 100 also includes a switch body 5 fixedly mounted on the housing 1 and a switch trigger 4 movably mounted on the housing 1. The switch trigger 4 moves between a release position and a trigger position that triggers the switch body 5. Specifically, the switch body 5 is constructed as a micro switch, which is installed inside the grip 13 and electrically connected to the control circuit (not shown) of the pruning machine 100. The switch trigger 4 is rotatably connected to the grip 13 and can be operated by the user to move between the release position and the trigger position. When the switch trigger 4 is in the release position, it is separated from the switch body 5. At this time, the switch body 5 is not triggered, and the pruning machine 100 is in the off state. When the user presses or pushes the switch trigger 4 to the trigger position, the switch trigger 4 contacts the switch body 5 and presses the switch body 5. At this time, the switch body 5 is triggered, and the pruning machine 100 is in the start state.

[0039] It should be noted that the micro switch structure of the switch body 5 is only one optional embodiment of this utility model. In other embodiments, the switch body 5 can be a non-contact switch, such as a Hall plate. Correspondingly, the switch trigger 4 is connected to a magnet. The Hall plate obtains the position of the switch trigger 4 by detecting changes in the magnetic field, and thereby controls the start and stop of the pruning machine 100.

[0040] The housing 1 includes an opening 15 through which the switch trigger 4 passes. The pruning machine 100 also includes a first blocking member 6 connected to or integrally formed with the switch trigger 4. The first blocking member 6 moves together with the switch trigger 4, and when the switch trigger 4 moves between the release position and the trigger position, the first blocking member 6 covers at least part of the opening 15. In this way, when the user operates the switch trigger 4, large grass clippings, branches, etc. in the outdoor environment are blocked by the first blocking member 6 and cannot flow into the housing 1 through the opening 15, thereby preventing the electronic components inside the housing 1 from being affected and malfunctioning.

[0041] The housing 1 also includes a first receiving cavity 131 located at least partially below the switch trigger 4. A first shield 6 is disposed within the first receiving cavity 131, and the first receiving cavity 131 communicates with the opening 15. Specifically, the grip portion 13 defines the first receiving cavity 131 below the switch trigger 4 through its inner wall. The opening 15 is opened on the grip portion 13 and communicates with the first receiving cavity 131. The first shield 6 is also disposed within the first receiving cavity 131. Thus, when the user operates the switch trigger 4, small dust particles, grass clippings, etc., in the outdoor environment will flow into the housing 1 through the gap between the first shield 6 and the opening 15. After being shielded by the first shield 6 and by gravity, they will fall into the first receiving cavity 131, thereby preventing the dust particles and grass clippings from entering the housing 1 and scattering everywhere.

[0042] The housing 1 also includes a chip discharge port 16 disposed below the opening 15, which communicates with the first receiving cavity 131. The pruning machine 100 also includes a cover plate 133 that selectively closes the chip discharge port 16, and the cover plate 133 is rotatably connected to the outside of the housing 1. Specifically, both the chip discharge port 16 and the cover plate 133 are formed on the grip portion 13. The chip discharge port 16 is disposed below the opening 15 and communicates with the first receiving cavity 131, while the cover plate 133 can be rotated by the user to selectively close or open the chip discharge port 16. Thus, after the pruning machine 100 has been working for a period of time, the user can open the cover plate 133 and empty the dust and grass clippings contained in the first receiving cavity 131 out of the housing 1 through the chip discharge port 16, thereby preventing excessive accumulation of dust and grass clippings in the first receiving cavity 131 and affecting the normal operation of the pruning machine 100.

[0043] Furthermore, in the height direction of the pruning machine 100, the cover plate 133 is installed between the opening 15 and the chip discharge port 16. In this way, when the user pours out the dust and grass clippings in the first receiving cavity 131, the cover plate 133 located above the chip discharge port 16 will not be contaminated with the dust and grass clippings. This means that when the user cleans the dust and grass clippings accumulated in the grip part 13, there is no need to clean the cover plate 133 separately, thus improving the user experience.

[0044] Furthermore, the opening direction of the chip discharge port 16 is inclined downward, so that the dust and grass clippings contained in the first receiving cavity 131 have a tendency to move towards the inclined downward opening of the chip discharge port 16 due to gravity. This makes it possible for the user to empty the dust and grass clippings in the first receiving cavity 131 without having to empty the pruning machine 100 in large quantities, thus improving the user experience.

[0045] The pruning machine 100 also includes a second shield 7 connected to or integrally formed with the switch trigger 4. The second shield 7 extends at least partially from the switch trigger 4 in a lateral direction. Specifically, the extension direction of the second shield 7 is substantially parallel to the horizontal plane, and the second shield 7 is located above the first shield 6 and above the opening 15. Thus, when the user operates the switch trigger 4, small dust particles, grass clippings, etc. in the outdoor environment will flow into the housing 1 through the gap between the first shield 6 and the opening 15. The second shield 7 can further block the dust particles and grass clippings to ensure that they fall into the first receiving cavity 131.

[0046] It should be noted that the fact that the extension direction of the second shielding member 7 is basically horizontal is only one optional embodiment of this utility model. In other embodiments, the second shielding member 7 may also be inclined relative to the horizontal plane, so as to ensure that the second shielding member 7 extends at least partially laterally so that the second shielding member 7 can block the dust and grass clippings in the height direction of the pruning machine 100.

[0047] The housing 1 also includes a second receiving cavity 132 located at least partially above the switch trigger 4, the switch body 5 is disposed in the second receiving cavity 132, the first receiving cavity 131 and the second receiving cavity 132 are in fluid communication, and the second blocking member 7 is located at the connection between the first receiving cavity 131 and the second receiving cavity 132.

[0048] Specifically, the gripping part 13 defines a second receiving cavity 132 above the switch trigger 4 through the inner wall. The second receiving cavity 132 is located above the first receiving cavity 131, and due to the presence of the opening 15, the first receiving cavity 131 and the second receiving cavity 132 are in fluid communication. The second blocking member 7 is disposed at the junction of the first receiving cavity 131 and the second receiving cavity 132. Thus, on the one hand, when the user operates the switch trigger 4, small dust particles and grass clippings in the outdoor environment will flow into the housing 1 through the gap between the first shield 6 and the opening 15. The second shield 7 can further prevent the dust particles and grass clippings from flowing into the second receiving cavity 132 and affecting the normal operation of the switch body 5, thereby extending the service life of the switch body 5. On the other hand, when the user tilts the pruning machine 100 to trim shrubs located in low places, the dust particles and grass clippings in the first receiving cavity 131 have a tendency to flow out of the first receiving cavity 131 due to gravity. The second shield 7 can stop the dust particles and grass clippings in the first receiving cavity 131 and further prevent the dust particles and grass clippings from flowing into the second receiving cavity 132.

[0049] This utility model is not limited to the specific embodiments described above. Those skilled in the art will readily understand that many other alternative solutions to the pruning machine of this utility model can be found without departing from the principles and scope of this utility model. The scope of protection of this utility model is determined by the claims.
