The specific embodiment of the present invention provides a household vegetable cutting device, as shown in FIG. 1 , which is a schematic diagram of the overall structure of the embodiment of the present invention, including a device body 1 for placing vegetables to be cut and a device body 1 for supporting the device body 1. Body bracket 11 . In this embodiment, the device body 1 is of a cubic structure, with a casing 12 enclosed on the side surface, the upper and lower ends of the casing 12 are open, and a vertical axial guide rail 16 is provided at each of the four corners inside the casing 12. Four guide rails 16 is supported in the housing 12 and corresponds to the four basic brackets 11 at the lower end of the connection device body 1. The upper opening of the housing 12 is covered with an upper cover 13. One side of the upper cover 13 is hinged with the housing 12 through a hinge 131, and the upper cover 13 is on the other side. One side is clamped with the casing 12 through the buckle 132 ; a funnel 15 is provided at the opening of the lower end of the casing 12 , and the lower end surface of the funnel 15 is significantly higher than the lower end surface of the main body bracket 11 . The casing 12 is also provided with a blade group 3, the blade group 3 is horizontal, and its four corners are provided with rolling wheels 31, and the blade group 3 is slidably connected with the four guide rails 16 through its four rolling wheels 31, so as to reduce friction. loss. The device body 1 also includes a transmission mechanism 2. In this embodiment, the transmission mechanism 2 is fixed on one of the body brackets 11, and the power output end of the transmission mechanism 2 is connected to the blade group 3 by transmission, and can drive the blade group 3. A reciprocating motion is made along the axial direction of the guide rail 16 . The lower end of the casing 12 is also provided with an annular tool holder 14 . When the device of the present invention is not working, the blade group 3 is placed on the blade holder 14 , and the blade holder 14 supports the blade group 3 . When cutting vegetables, open the top cover 13, put in the vegetables, snap the top cover 13, and the transmission mechanism 2 drives the blade set 3 to move linearly from bottom to top, thereby pressing the vegetables on the blade set 3 and the top cover. 13 until the vegetables are cut. Since the blade set 3 includes neatly arranged and criss-crossed blades, there is a gap between the blades, and the vegetables cut into small pieces slide down through the gap and fall into the pre-placed container through the funnel 15 . Since the upper cover 13 cooperates with the blade set 3 to complete the process of pressing and cutting vegetables, it plays a role of longitudinal limit, so it can also be called a limit plate.

More specifically, as shown in FIG. 2, it is a schematic structural diagram of the transmission mechanism in the embodiment of the present invention, including a stepping motor 21, a screw rod 22, a nut 23, and a slider 24. The upper end of the slider 24 is provided with a screw 25. The blade set 3 has a reserved through hole, the screw 25 passes through the through hole on the blade set 3 , and then cooperates with the nut 26 to fix the blade set 3 on the slider 24 . Since the blade set 3 and the slider 24 are detachably connected, it is not only conducive to cleaning and replacing the blade set 3, but also for different vegetable cutting requirements such as shredding, slicing, dicing, and slicing. The blade set 3 of the style, this embodiment provides a total of four styles: a shredding blade set, a slicing blade set, a dicing blade set, and a dicing blade set. Vegetable cutting requirements for slicing, dicing, and slicing. The power output end of the stepping motor 21 is fixedly connected with the vertical screw 22 , the screw nut 23 is threadedly connected with the screw rod 22 , and the screw nut 23 is fixedly connected in the slider 24 . When the stepping motor 21 drives the screw rod 22 to rotate, the driving screw nut 23 moves linearly in the vertical direction, thereby driving the slider 24 and the blade group 3 to move linearly in the vertical direction. In this embodiment, the guide rail 16 is clamped in the chute of the slider 24 to be slidably connected with it, and plays a role of limiting and guiding the slider 24 and the blade set 3 .

More specifically, in order to realize the function of reciprocating motion of the blade set 3 in the vertical direction, the stepping motor 21 is electrically connected with an upper limit switch 4 , a lower limit switch 5 and a battery 6 , and the upper limit switch 4 is arranged near the upper end of the casing 12 . The position can be set on the inner side of the upper cover 13 or the upper end of the inner side of the casing 12. When the blade group 3 moves upward to press the upper limit switch 4, the corresponding circuit is disconnected, and the stepping motor 21 stops driving the blade group 3 to continue to move upward; the lower limit The position switch 5 is located close to the lower end of the casing 12, and can be located at the inner side of the casing 12 near the lower end or the inner side of the tool holder 14. When the blade group 3 moves down to press the lower limit switch 5, the corresponding circuit is disconnected, and the stepping motor 21 Stop driving the blade set 3 to continue moving downward. Through the cooperation of the upper limit switch 4 and the lower limit switch 5 , the reciprocating motion of the blade group 3 in the vertical direction under the driving of the stepping motor 21 can be realized.

In this embodiment, the lower limit switch 5 also serves as a start switch. Specifically, as shown in FIG. 7 , which is a schematic diagram of the electrical connection of the stepper motor in the embodiment of the present invention, the battery 6 is connected to the stepper motor 21 through the lower limit switch 5 . Connected in series, the lower limit switch 5 plays the role of turning on or off the loop, thereby realizing the switching function. When the lower limit switch 5 is closed and turned on, assuming that the two upper limit switches 4 are deflected upward in the initial state, the direction of the current flowing through the stepper motor 21 is from up to down, and the stepper motor 21 drives the blade group 3 under the power supply of the battery 6 Move upward until the upper limit switch 4 is pressed, so that the two upper limit switches 4 are deflected downward. It can be seen from the circuit analysis that the direction of the current flowing through the stepping motor 21 is converted from bottom to top, and the stepping motor 21 changes immediately. Turning, drive the blade set 3 to move downward until the lower limit switch 5 is pressed to disconnect the circuit, and a vegetable cutting operation is completed. At this time, the blade set 3 is located on the blade holder 14 and is supported by the blade holder 14 .

The above are only the preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, without departing from the technical principle of the present invention, several improvements and modifications can also be made. These improvements and modifications It should also be regarded as the protection scope of the present invention.
