[0028] See also Figures 1 to 4 ; This embodiment provides an electric shredder, including a base 10, a shredding blade 20, a spiral screw rod 30, a food holder 31, and an electric drive assembly; a knife holder 11 and a screw seat 12 are relatively spaced apart on the base 10, and a wire outlet hole 13 is opened on the knife holder 11, and the shredding blade 20 is fixed on the knife holder 11 and is located on one side of the wire outlet hole 13; the spiral screw rod 30 is passed through the screw seat 12, one end of the spiral screw rod 30 extends toward the side of the screw seat 12 opposite to the knife holder 11, and the other end of the spiral screw rod 30 extends toward the side of the screw seat 12 away from the knife holder 11, and the food holder 31 is connected to the end of the spiral screw rod 30 extending toward the knife holder 11, and the food holder 31 is opposite to the shredding blade 20; the electric drive assembly is arranged on the screw seat 12, and the electric drive assembly is drivingly connected to the spiral screw rod 30 and is used to drive the spiral screw rod 30 to rotate.

[0029] Thus, in the electric shredder provided by the present invention, a screw rod 30 is axially movably provided on the screw seat 12, and an electric drive assembly for driving the screw rod 30 to rotate spirally is provided on the screw seat 12, and a food material holder 31 for fixing the food material to be processed is fixed at one end of the screw rod 30 facing the shredding blade 20. In this way, the electric drive assembly is used to directly drive the screw rod 30 to rotate, and the screw rod 30 can move spirally in the axial direction during the rotation process, and the food material holder 31 is used to press the food material and move it toward the shredding blade 20, so that the food material is continuously shredded by the shredding blade 20. After the shredding is completed, the electric drive assembly drives the screw rod 30 to rotate in the opposite direction, so that the screw rod 30 can be spirally moved in the direction away from the shredding blade 20, so that the screw rod 30 is reset, and the food material can be put in again to carry out the shredding operation. Thus, the present invention provides an electric shredder that is compact and very convenient and quick to use, which can achieve a time-saving and labor-saving shredding effect.

[0030] In this embodiment, a first threaded bearing hole 14 and a second threaded bearing hole 15 are spaced apart on the screw seat 12. The first threaded bearing hole 14 and the second threaded bearing hole 15 are coaxially arranged, and the screw rod 30 is threadedly inserted into the first threaded bearing hole 14 and the second threaded bearing hole 15. In this way, this embodiment utilizes the coaxial arrangement of the first threaded bearing hole 14 and the second threaded bearing hole 15 to enable the screw rod 30 to be threadedly inserted into the first threaded bearing hole 14 and the second threaded bearing hole 15.

[0031] In this embodiment, one end of the screw rod 30 extending away from the tool holder 11 is coaxially connected to a limit member 33, and the diameter of the limit member 33 is larger than the outer diameter of the screw rod 30. The limit member 33 can be, but is not limited to, a disc-shaped structure.

[0032] In this embodiment, the food holder 31 is a disc-shaped structure, coaxially arranged with the screw 30. Several food inserts 32 are provided on the end surface of the food holder 31 opposite the shredding blade 20. This allows the food inserts 32 to further secure the food. Furthermore, a food positioner 16 is provided on the side of the knife holder 11 opposite the food holder 31. This food positioner 16 is located at one end of the shredding hole 13 and has a cylindrical or conical structure, allowing one end of the food to be inserted into the food positioner 16 while the other end of the food is securely secured by the food holder 31.

[0033] In this embodiment, a nut wheel 40 is rotatably provided on the screw seat 12, and the nut wheel 40 is located between the first threaded bearing hole 14 and the second threaded bearing hole 15. The screw rod 30 is threadedly penetrated in the nut wheel 40, and the electric drive component is transmission-connected to the nut wheel 40. The electric drive component is used to drive the nut wheel 40 to rotate circumferentially, and then drive the screw rod 30 to rotate and move along its axial direction through the nut wheel 40.

[0034] It can be understood that the screw seat 12 of this embodiment is designed with a circumferentially rotating nut wheel 40, and the nut wheel 40 is confined in the screw seat 12 and can only rotate circumferentially around its axis and cannot move along its axial direction; in this way, when the nut wheel 40 is driven by the electric drive assembly, the nut wheel 40 is threadedly connected to the screw rod 30, so that the screw rod 30 can move spirally in the axial direction, so as to achieve the goal of moving the food holder 31 towards or away from the shredding blade 20.

[0035] In this embodiment, the electric drive assembly includes a power supply unit and a drive motor 50. The power supply unit is electrically connected to the drive motor 50. The output end of the drive motor 50 is coaxially and rigidly connected to a drive wheel 51. The drive wheel 51 is connected to the nut wheel 40 via a belt 52. In addition, the electric drive assembly also includes a drive circuit board, a power switch 53, a work button 54, and a reset button 55. The power switch 53, the work button 54, and the reset button 55 are respectively electrically connected to the drive circuit board, and the power switch 53, the work button 54, and the reset button 55 are respectively disposed on the surface of the screw seat 12. The drive circuit board is electrically connected to the drive motor 50. In addition, in order to prevent the spiral screw 30 from moving too much during the spiral movement of squeezing food, the electric drive component of this embodiment also includes a micro switch 56, which is electrically connected to the drive circuit board. The micro switch 56 is set on the moving path of the limit member 33. When the spiral screw 30 drives the limit member 33 to move and triggers the micro switch 56, the micro switch 56 is triggered, and the drive circuit board controls the drive motor 50 to rotate in the opposite direction, so that the spiral screw 30 retreats and moves away from the cutting blade 20.

[0036] The power supply is a rechargeable power supply with a charging port. The screw seat 12 has a notch corresponding to the charging port. This allows the user to charge the power supply. Furthermore, the drive motor 50 of this embodiment utilizes a conventional stepper motor, enabling forward and reverse rotation of the output shaft of the drive motor 50.

[0037] When it is necessary to shred the food, first turn on the power switch 53, then press the reset button 55 to make the drive motor 50 work, thereby driving the nut wheel 40 to rotate, and causing the screw rod 30 to spirally move in the direction away from the shredding blade 20, so that the distance between the food holder 31 and the shredding blade 20 is sufficient to place the food to be shredded, then release the reset button 55, and after placing the food between the shredding blade 20 and the food holder 31, press the working switch to make the drive motor 50 rotate in the opposite direction, thereby causing the screw rod 30 to spirally move in the direction close to the shredding blade 20, so that the food holder 31 is pressed against the food. At this time, the food can be shredded with the cooperation of the shredding blade 20 and the screw rod 30.

[0038] See also Figure 5 , which is a schematic diagram of a driving circuit board of this embodiment, the driving circuit board may include a control chip, a first switch module and a second switch module; the control chip includes a first switch control terminal;

[0039] The first switch control end of the control chip is respectively connected to the driving end of the first switch module and the driving end of the second switch module, the power supply unit is connected to the first end of the first switch module, the second end of the first switch module is connected to the first end of the second switch module via the power switch and the drive motor, and the second end of the second switch module is grounded.

[0040] like Figure 5 As shown, the control chip is IC1, the first switch control terminal is IO5; the first switch module includes a transistor Q1 and a MOS transistor MOS1, and the second switch module is MOS2; the power supply is a +12V power supply; the power switch CN5 and the motor VH1 are connected. When IO5 drives Q1, MOS1, and MOS2 to conduct, the +12V power supply is connected to ground through MOS1, the power switch CN5, the motor VH1, and MOS2 in sequence, forming a loop, causing the motor VH1 to rotate in a first direction. MOS2 can be grounded via multiple parallel resistors (such as R20-R25).

[0041] The driving circuit board may further include a third switch module and a fourth switch module; the control chip includes a first switch control terminal;

[0042] The first switch control end of the control chip is respectively connected to the driving end of the third switch module and the driving end of the fourth switch module, the power supply unit is connected to the first end of the third switch module, the second end of the third switch module is connected to the first end of the fourth switch module via the power switch and the drive motor, and the second end of the fourth switch module is grounded.

[0043] like Figure 5As shown, the control chip is IC1, the first switch control terminal is IO4; the third switch module includes a transistor Q3 and a MOS transistor MOS3; the fourth switch module is MOS4; the power supply is a +12V power supply; the power switch CN5 and the motor VH1 are connected. When IO5 drives Q3, MOS3, and MOS4 to conduct, the +12V power supply is connected to ground in sequence through MOS3, the motor VH1, the power switch CN5, and MOS4, forming a loop, causing the motor VH1 to rotate in a first direction. MOS4 can be grounded via multiple parallel resistors (such as R20-R25).

[0044] Specifically, such as Figure 5 As described above, in this embodiment, CN2, CN4, R3, R4, R7, and R9 can be used to transmit signals to AN0 and AN16 of IC1 to achieve first and second gears of the drive motor. When the drive motor is stuck, the current flowing through multiple parallel resistors (such as R20-R25) can be calculated using the formula current × resistance = voltage to obtain a voltage. This voltage is then converted into an analog value and transmitted to pin 4 of IC1 via R19 and C7 to detect whether the motor is stuck.

It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention.
