Description

Technical Field

[0001] This utility model relates to the technical field of garden pruning, and in particular to electric shears and garden pruning equipment. Background Technology

[0002] Electric shears are a common tool in garden construction. They have a built-in motor as a drive unit, which moves the blade assembly to construct the target area.

[0003] In the prior art, electric shears include a housing, a drive motor housed within the housing, and a blade assembly connected to the drive motor via a transmission device. When in use, activating the drive motor causes it to move the blade assembly at high speed via the transmission assembly, thus trimming the target material.

[0004] However, the trimming process is usually continuous, so heat will continue to accumulate inside the casing, causing the internal temperature to rise continuously. This will not only affect the normal operation of the drive motor, but also affect the operator's grip on the casing. Utility Model Content

[0005] The purpose of this invention is to provide electric shears and garden trimming equipment, which solves the problem in the prior art that the temperature inside the casing is prone to continuous rise, which not only affects the normal operation of the drive motor, but also affects the operator's grip on the casing.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] In a first aspect, this utility model provides electric scissors, which include:

[0008] The outer casing has an air inlet on one side and an air outlet on the other side.

[0009] The motor is disposed inside the housing and located between the air inlet and the air outlet. The motor housing has an air inlet hole at one end near the air inlet and an air outlet hole at the other end near the air outlet.

[0010] A sealing component is disposed in the housing and abuts against the outer side wall of the motor housing of the motor to seal the space between the motor housing and the housing;

[0011] A fan is installed inside the motor housing of the motor;

[0012] The blade assembly is disposed in the housing 1 and connected to the motor via a transmission assembly.

[0013] Optionally, the enclosure component includes:

[0014] The first sealing plate is fixed to the inner wall of the outer casing and near the air inlet. The first sealing plate is sealed and fitted to the outer side of the motor housing of the motor.

[0015] Optionally, the enclosure component further includes:

[0016] The second sealing plate is fixed to the inner wall of the outer casing and located between the air inlet and the air outlet. The inner side of the second sealing plate is sealed and fitted to the outer side of the motor housing of the motor.

[0017] Optionally, the enclosure component further includes:

[0018] The third sealing plate is fixed to the inner wall of the outer shell and located on the side of the second sealing plate away from the air inlet. The third sealing plate and the second sealing plate form a receiving space. The transmission component is located in the receiving space, and the air outlet is connected to the receiving space.

[0019] Optionally, the fan is positioned close to the air outlet.

[0020] Optionally, multiple air inlets are provided at circumferential intervals around the motor housing of the motor.

[0021] Optionally, multiple air outlets are provided at circumferential intervals around the motor housing of the motor.

[0022] Optionally, an air inlet is provided on each of the opposite sides of the outer casing;

[0023] Alternatively, an air outlet may be provided on each of the opposite sides of the outer casing.

[0024] Optionally, the housing has a front end, a rear end, and a grip portion located between the front end and the rear end, with the air inlet located at the rear end and the air outlet located at the front end.

[0025] Secondly, this utility model provides a garden pruning device, which includes:

[0026] Electric scissors as described in any one of the first aspects;

[0027] A control device is connected to the electric scissors.

[0028] The beneficial effects of this utility model are:

[0029] Firstly, during trimming, the motor is started, and the transmission assembly drives the blade assembly to trim the target. During trimming, the fan also runs, drawing air in through the air inlet. The air then enters the motor housing through the air inlet hole and exits through the air outlet hole. The air exiting the motor housing then exits through the air outlet hole, thus achieving efficient heat dissipation for the motor inside the housing. Therefore, when this electric shears is in use, due to the tight fit between the sealing assembly and the motor housing, air mainly flows into the motor housing through the air inlet and air inlet hole, and then flows out through the air outlet hole and air outlet hole. This ensures that air mainly or exclusively flows within the motor housing, reducing the possibility of it diffusing outside the housing. This achieves efficient heat dissipation for the internal structure of the motor housing, reducing the possibility of heat accumulation and continuous temperature rise, ensuring normal motor operation, and avoiding any issues with the operator's grip on the housing.

[0030] Secondly, when the garden pruning equipment is in use, the electric shears can maintain efficient heat dissipation, so that heat will not accumulate inside the electric shears, ensuring that the electric shears can continue to operate normally, thereby improving the stability of the garden pruning equipment.

[0040] This utility model provides electric shears and garden trimming equipment.

[0041] Reference Figures 1 to 4 The electric scissors include a housing 1, a motor, a sealing assembly 2, a fan 3, and a blade assembly 4. The housing 1 has an air inlet 11 on one side and an air outlet 12 on the other side. The motor is located inside the housing 1, between the air inlet 11 and the air outlet 12. The motor housing 5 has an air inlet hole 51 near the air inlet 11 and an air outlet hole 52 near the air outlet 12. The sealing assembly 2 is located in the housing 1 and fits against the outer wall of the motor housing 5 to seal the space between the motor housing 5 and the housing 1. The fan 3 is located inside the motor housing 5. The blade assembly 4 is located in the housing 1 and connected to the motor via a transmission assembly 6.

[0042] Specifically, the outer casing 1 is elongated and is formed by sequentially splicing multiple outer casings 1 to create a closed structure. The outer casing 1 has a front end 13, a rear end 14, and a gripping portion 15 located between the front end 13 and the rear end 14. The middle part of the outer casing 1 is the gripping portion for the operator to hold. An air inlet 11 is located at the rear end 14, and an air outlet 12 is located at the front end 13. A blade assembly 4 is provided at the front end 13. The blade assembly 4 includes a fixed blade and a movable blade. A motor drives the movable blade to move relative to the fixed blade via a transmission assembly 6 for trimming operations. A trigger 16 connected to the blade assembly 4 is also provided at the front end 13, allowing the operator to control the blade assembly 4 by operating the trigger 16 after gripping the gripping portion 15.

[0043] A sealing component 2 is installed on the inner wall of the outer casing 1. The inner side of the sealing component 2 is fixedly connected to the motor housing 5 of the motor. An air inlet 51 is provided at the end of the motor housing 5 near the air inlet 11, and an air outlet 52 is provided at the end of the motor housing 5 near the air outlet 12, so as to form a channel for gas flow inside the motor housing 5. At the same time, the outer wall of the motor housing 5 fits tightly with the sealing component 2, thereby sealing the space between the motor housing 5 and the outer casing 1, ensuring that gas can only flow into the interior of the motor housing 5. A fan 3 is also installed inside the motor housing 5, and the fan 3 can be an axial flow fan 3.

[0044] During trimming, the motor is started, and the transmission component 6 drives the blade assembly 4 to move, thus trimming the target. During the trimming process, the fan 3 also runs, drawing air in through the air inlet 11. The air then enters the motor housing 5 through the air inlet 51 and exits through the air outlet 52. The air exiting the motor housing 5 then exits the outer casing 1 through the air outlet 12, thereby achieving efficient heat dissipation of the motor inside the motor housing 5. In this way, when the electric shears are in use, due to the tight fit between the sealing component 2 and the motor housing 5, air mainly flows into the motor housing 5 through the air inlet 11 and the air inlet 51, and then flows out through the air outlet 52 and the air outlet 12. This ensures that the air mainly or only flows inside the motor housing 5, reducing the possibility of it diffusing outside the motor housing 5. This achieves efficient heat dissipation of the internal structure of the motor housing 5, reducing the possibility of heat accumulation inside the motor housing 5 and a continuous rise in temperature, ensuring the normal operation of the motor, and avoiding any issues that may affect the operator's grip on the outer casing 1.

[0045] Optionally, the enclosure assembly 2 includes a first enclosure plate 21. The first enclosure plate 21 is fixed to the inner wall of the housing 1 and located near the air inlet 51, and the first enclosure plate 21 is sealed and fitted to the outer side of the motor housing 5 of the motor.

[0046] Specifically, a first sealing plate 21 is circumferentially arranged on the inner wall of the outer casing 1. The two can be an integral structure or fixed by welding or bonding. The first sealing plate 21 can be sealed and fitted to the outer wall of the motor housing 5, forming a surface fit. A sealing film or other structure can also be provided at the fit to ensure good airtightness. The first sealing plate 21 is located near the air inlet 51 on the motor housing 5. When the air inlet 51 is located on the end face of the motor housing 5, the first sealing plate 21 can fit against the edge of the end face of the motor housing 5. When the air inlet 51 is located on the side wall of the motor housing 5, the first sealing plate 21 can fit against the outer wall of the motor housing 5.

[0047] By setting a first sealing plate 21 near the air inlet 51, the part of the motor housing 5 near the air inlet 51 forms a closed fit with the first sealing plate 21. Thus, the air entering from the air inlet 11 can only enter the motor housing 5 through the air inlet 51 and will not enter the gap between the motor housing 5 and the outer shell 1. This effectively reduces the possibility of air diffusion inside the outer shell 1 and ensures efficient heat dissipation inside the motor housing 5.

[0048] Optionally, the enclosure assembly 2 further includes a second enclosure plate 22. The second enclosure plate 22 is fixed to the inner wall of the housing 1 and located between the air inlet 51 and the air outlet 52, and the inner side of the second enclosure plate 22 is sealed and fitted to the outer side of the motor housing 5 of the motor.

[0049] Specifically, the second sealing plate 22 can be arranged opposite to the first sealing plate 21, and the second sealing plate 22 is positioned close to the air outlet 52. In this embodiment, the air outlet 52 is located on the side wall of the motor housing 5. The inner side of the second sealing plate 22 and the outer side of the motor housing 5 form a surface fit, and a sealing film or other structure can be provided at the fit to ensure a good sealing effect.

[0050] By setting the second sealing plate 22, after the air is discharged from the air outlet 52, the air can only leave the outer casing 1 through the air outlet 12 and will not flow back between the outer casing 1 and the motor casing 5, thereby ensuring that the heat can be smoothly carried away from the motor casing 5 and further reducing the possibility of heat accumulation inside the outer casing 1.

[0051] Optionally, the enclosure assembly 2 also includes a third enclosure plate 23. The third enclosure plate 23 is fixed to the inner wall of the housing 1 and is located on the side of the second enclosure plate 22 away from the air inlet 51. A receiving space is formed between the third enclosure plate 23 and the second enclosure plate 22. The transmission assembly 6 is located in the receiving space, and the air outlet 12 communicates with the receiving space.

[0052] Specifically, the third enclosure plate 23 can form an integral structure with the outer shell 1, and it can be distributed in multiple segments according to the shape of the transmission component 6 to adapt to the installation space and cooperate with the second enclosure plate 22 to form a receiving space, with the air outlet 12 opening directly corresponding to the receiving space.

[0053] By setting the third enclosure plate 23 to form an accommodating space, on the one hand, the air flow range can be further restricted to ensure that the air discharged from the air outlet 52 can quickly pass through the accommodating space and be discharged from the air outlet 12. On the other hand, when the air enters the accommodating space, the air can also absorb the heat generated by the transmission component 6 during operation to achieve heat dissipation of the transmission component 6, thereby further reducing the possibility of heat accumulation inside the housing 1.

[0054] Optionally, fan 3 is positioned close to air outlet 52.

[0055] Specifically, when the fan 3 is running, because the fan 3 is located close to the air outlet 52, it can first draw out the air near the air inlet 51 in the motor housing 5 to form a negative pressure. Then, the air outside the air inlet 51 will gradually pass through the air inlet 51 and enter the motor housing 5. As the air gradually flows through each component, it can dissipate heat from each component. Then, after the air comes into contact with the fan 3, it is blown by the fan 3 towards the air outlet 52. Because the fan 3 is close to the air outlet 52, the air can be quickly blown out through the air outlet 52, thereby increasing the air flow rate and further improving the overall heat dissipation effect.

[0056] Optionally, multiple air inlets 51 are spaced apart circumferentially around the motor housing 5 of the motor. Multiple air outlets 52 are spaced apart circumferentially around the motor housing 5 of the motor.

[0057] Specifically, the end of the motor housing 5 furthest from the transmission component 6 is the bottom end. Multiple through holes 51 are formed on the bottom surface of this bottom end, serving as air inlets 51. These air inlets 51 are spaced apart around the circumference of the motor housing 5. The shapes of the multiple air inlets 51 can be the same or different; this invention does not limit this. Multiple through holes 52 are also spaced apart on the sidewall of the motor housing 5 closest to the transmission component 6, serving as air outlets 52. The air outlets 52 can be circular or other shapes; this invention does not limit this. The multiple air outlets 52 can be equally spaced around the circumference of the motor housing 5.

[0058] By opening multiple air inlets 51, a large amount of air can be ensured to enter the motor housing 5, thereby improving the heat dissipation effect inside the motor housing 5. The setting of multiple air outlets 52 can improve the exhaust effect, so that the air inside the motor housing 5 can be smoothly discharged.

[0059] Optionally, an air inlet 11 is provided on each of the opposite sides of the outer casing 1. An air outlet 12 is provided on each of the opposite sides of the outer casing 1.

[0060] Specifically, an air inlet 11 and an air outlet 12 are respectively provided on both sides of the outer casing 1 in the thickness direction. The two air inlets 11 are arranged opposite to each other, and the two air outlets 12 are also arranged opposite to each other, so that an air inlet 11 and an air outlet 12 are provided on each side of the outer casing 1. However, it should be understood that an air inlet 11 and an air outlet 12 can also be provided on only one side of the outer casing 1. Both the air inlet 11 and the air outlet 12 are composed of multiple strip-shaped through holes, which effectively increases the communication area of ​​the air inlet 11 and the air outlet 12, ensuring that a large amount of air can enter the outer casing 1 and quickly flow out of the outer casing 1, while also preventing impurities from entering the interior of the outer casing 1.

[0061] Reference Figure 5 The garden trimming equipment includes electric shears as described in any of the above descriptions and a control device 7. The control device 7 is connected to the electric shears.

[0062] When using this garden pruning equipment, the operator controls the operation of the electric shears. The electric shears maintain efficient heat dissipation during use, preventing heat buildup inside and ensuring continuous normal operation, thus improving the stability of the garden pruning equipment.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
