[0018] The following is combined with Figure 1 - Figure 4 This application is described in further detail.

[0019] Example 1:

[0020] A hedge trimmer air guide cover, referring to Figure 1 - Figure 4 , including an air scoop body 1, and filters 10 are provided on both sides of the outer surface of the air scoop body 1. By installing the two filters 10 on both sides of the air scoop body 1, the air is filtered through the filters 10 to prevent dust from entering the interior of the air scoop body 1 and causing damage to the electrical components. A number of fixing plates 5 are fixedly connected to both sides of the outer wall of the air scoop body 1. The outer surface of the air scoop body 1 is rotatably connected to a reciprocating screw 6 through a number of fixing plates 5, wherein the reciprocating screw 6 is a form of a three-dimensional cam pair, which is manifested as two thread grooves with the same pitch and opposite rotation directions, and the two ends are connected with a transition curve. Through the rotation of the screw, the side of the spiral groove pushes the moving block placed in the spiral groove to perform axial reciprocating motion. A number of slide grooves 2 are provided on the outer surface of the air scoop body 1 corresponding to both sides of the filter 10, and the inner side of the slide groove 2 The outer surface of the air guide cover body 1 is slidably connected with a slider 13, and the outer surface of the air guide cover body 1 is slidably connected with the connecting plate 4 through two reciprocating screw rods 6 and several sliders 13. The size of the slide groove 2 is adapted to the size of the slider 13, so that the slider 13 can slide inside the slide groove 2. The two sliders 13 are respectively installed on both sides of the connecting plate 4 to limit the movement direction of the connecting plate 4, so that the connecting plate 4 can only avoid moving along the filter screen 10. The reciprocating screw rod 6 is connected to the connecting plate 4 so that the reciprocating screw rod 6 rotates to drive the connecting plate 4 to reciprocate left and right. The side surface of the air guide cover body 1 is rotatably connected to the driven wheel 9 through the reciprocating screw rod 6 on one side, and the side surface of the air guide cover body 1 is rotatably connected to the driving wheel 7 through the reciprocating screw rod 6 on the other side, so as to achieve the effect of facilitating the connecting plate 4 to reciprocate left and right.

[0021] Furthermore, the driving wheel 7 and the driven wheel 9 are connected through a transmission belt 8, and a servo motor 11 is fixedly connected to one side of the outer wall of the fixed plate 5, wherein the model of the servo motor 11 can preferably be HBS57, and the driving end of the servo motor 11 passes through the inner wall of the fixed plate 5 and is fixedly connected to one side of the reciprocating screw 6, and is connected to the reciprocating screw 6 on one side through the driving end of the servo motor 11, and the reciprocating screw 6 on one side is connected to the driving wheel 7, and the reciprocating screw 6 on the other side is connected to the driven wheel 9. At the same time, the driving wheel 7 and the driven wheel 9 are connected through the conveyor belt 8, so that the servo motor 11 drives the reciprocating screw 6 on one side to rotate, and can simultaneously drive the reciprocating screw 6 on the other side to rotate, thereby driving the connecting plates 4 on both sides to move back and forth left and right along the surface of the filter screen 10 at the same time, achieving the effect of driving the reciprocating screws 6 on both sides to rotate simultaneously.

[0022] Example 2

[0023] See also Figure 1-Figure 4 , and based on Example 1, further obtain:

[0024] Furthermore, several mounting grooves 14 are provided on the opposite sides of several connecting plates 4, and mounting blocks 17 are provided on the inner side of the mounting grooves 14. The outer walls of the connecting plates 4 are installed with brush plates 12 through two mounting blocks 17. The size of the mounting blocks 17 matches the size of the mounting grooves 14. By installing the two mounting blocks 17 on both sides of the brush plates 12, the mounting blocks 17 are aligned with the mounting grooves 14, so that the brush plates 12 are installed on the outer walls of the connecting plates 4, so that the connecting plates 4 move and drive the brush plates 12 to move back and forth left and right to clean the dust on the outer wall of the filter screen 10, thereby achieving the effect of facilitating the installation and disassembly between the connecting plates 4 and the brush plates 12.

[0025] Furthermore, a fixing hole 18 is opened on one side of the outer wall of the mounting block 17, and a threaded rod 15 is threadedly connected to the side of the outer wall of the connecting plate 4 corresponding to the fixing hole 18, wherein the outer wall spiral of the threaded rod 15 is set to twenty degrees. By matching the size of the threaded rod 15 with the size of the fixing hole 18, the threaded rod 15 is rotated to enter the fixing hole 18, so that the brush plate 12 is fixed on the outer wall of the connecting plate 4.

[0026] Furthermore, a knob 16 is fixedly connected to one side of the threaded rod 15, and a handle 3 is fixedly connected to one side of the outer wall of the brush plate 12. The knob 16 is installed on one side of the threaded rod 15, so that rotating the knob 16 drives the threaded rod 15 to rotate, so that rotating the knob 16 can rotate the threaded rod 15 into or out of the fixing hole 18, which is convenient for installing or disassembling the brush plate 12. The brush plate 12 is connected to the handle 3, so that by pulling the handle 3, the brush plate 12 can be pulled out from the outer wall of the connecting plate 4.

[0027] The implementation principle of the wind guide cover of a hedge trimmer according to the embodiment of the present application is as follows: when the device is in use, the servo motor 11 is started to drive the reciprocating screw 6 on one side to rotate, and the driving wheel 7 and the driven wheel 9 are connected to the two reciprocating screws 6 respectively, and then the reciprocating screws 6 on both sides are driven to rotate simultaneously, and the slider 13 slides inside the slide groove 2 and is connected to the connecting plate 4 through the slider 13, so that the moving direction of the connecting plate 4 is restricted, thereby The connecting plate 4 is driven to move back and forth along the outer wall of the filter 10, so that the brush plate 12 installed on the inner wall of the connecting plate 4 is driven to move back and forth to clean the dust on the surface of the filter 10. After cleaning, the threaded rod 15 is driven to move out from the inside of the fixing hole 18 by rotating the knob 16, so that the fixation of the mounting block 17 is released, and the handle 3 is installed on the outer wall of the brush plate 12, so that the brush plate 12 can be pulled out from the inner wall of the connecting plate 4 by pulling the handle 3, and then the brush plate 12 can be disassembled, which is convenient for maintenance and care of the brush plate 12.
