[0005] The fixed cutting component also includes a limiting part located above the fixed blade. The upper movable blade passes through the gap between the limiting part and the fixed blade when the movable cutting component rotates. Driven by the rotating upper movable blade, the waste passes through the gap between the limiting part and the fixed blade, and is sheared and shredded in the gaps between the upper movable blade and the limiting part, and between the upper movable blade and the fixed blade.

[0006] The upper side of the limiting part is an inclined surface that slopes downwards, which can prevent garbage from accumulating on it.

[0007] The fixed blade is stepped and bent, and the lower surface of the upper movable blade and the upper surface of the lower movable blade correspond to the shape of the fixed blade. That is, the fixed blade has stepped surfaces of different heights, which can increase the resistance to waste and improve the shearing effect.

Driven by the rotating lower movable blade, the waste passes through the gap between the fixed blade and the bottom wall, and is sheared and shredded in the gap between the lower movable blade and the fixed blade, and in the gap between the lower movable blade and the bottom wall.

[0011] A raised rib is provided on the bottom wall below the fixed blade, and the lower surface of the lower movable blade passes over the raised rib when the movable cutting component rotates. The raised rib is designed to intercept debris and increase friction with the lower movable blade, thereby grinding and pulverizing the debris.

[0012] The waste shredding assembly also includes a rotary drive mechanism; the output shaft of the rotary drive mechanism is connected to the movable cutter to drive the movable cutter to rotate.

[0013] Another objective of this utility model is to provide a kitchen waste disposal machine, including a machine body and the aforementioned waste shredding assembly, wherein the inner bucket is disposed in the machine body.

[0022] The following description, in conjunction with the accompanying drawings, further illustrates the proposed solution:

[0023] See appendix Figure 1-9 A waste shredding assembly includes an inner bucket 3, a fixed cutting element 1, a movable cutting element 2 that can rotate relative to the fixed cutting element 1, and a rotation drive mechanism 4.

[0024] The inner bucket 3 has a receiving cavity 30 for holding kitchen waste; the receiving cavity 30 includes a bottom wall 31 and a side wall 32 standing on the periphery of the bottom wall 31; the fixing and cutting member 1 is located above the bottom wall 31 and is fixedly connected to the side wall 32; specifically, it is fixedly connected to the side wall 32 by screws.

[0025] The movable cutting component 2 is rotatably mounted on the bottom wall 31; the rotary drive mechanism 4 is located below the inner barrel 3, and the output shaft of the rotary drive mechanism 4 is connected to the movable cutting component 2 to drive the movable cutting component 2 to rotate. The rotary drive mechanism 4 is a motor.

[0026] The fixed cutting component 1 includes a fixed blade part 11, a limiting part 12 located above the fixed blade part 11, and a connecting part 13 connecting the fixed blade part 11 and the limiting part 12.

[0027] The movable cutting component 2 includes an upper movable blade 21, a lower movable blade 22, and a central shaft 23. There is at least one upper movable blade 21 and multiple lower movable blades 22; the upper and lower movable blades 21 and 22 are spaced apart around the central shaft 23. The output shaft of the rotary drive mechanism 4 is connected to the central shaft 23.

[0028] In this embodiment, there is one upper movable blade section 21 and three lower movable blade sections 22. The center of the central shaft section 23 is on the rotation axis of the movable cutting member 2.

[0029] The upper movable blade 21 is higher than the fixed blade 11 and passes over the upper surface of the fixed blade 11 when the movable cutting member 2 rotates, so as to cooperate with the upper surface of the fixed blade 11 to shear and crush the waste; the lower surface of the upper movable blade 21 is provided with movable grinding teeth 211, which are used to cooperate with the upper surface of the fixed blade 11 to grind and crush the waste; the lower movable blade 22 is lower than the fixed blade 11 and passes over the lower surface of the fixed blade 11 when the movable cutting member 2 rotates, so as to cooperate with the lower surface of the fixed blade 11 to shear and crush the waste; the lower surface of the fixed blade 11 is provided with fixed grinding teeth 111, which are used to cooperate with the upper surface of the lower movable blade 22 to grind and crush the waste.

[0030] The upper movable blade 21 passes through the gap between the limiting part 12 and the fixed blade 11 when the movable cutting member 2 rotates. The waste is driven by the rotating upper movable blade 21 to pass through the gap between the limiting part 12 and the fixed blade 11, and is sheared and crushed in the gap between the upper movable blade 21 and the limiting part 12 and the gap between the upper movable blade 21 and the fixed blade 11.

[0033] The lower movable blade 22 passes through the gap between the fixed cutting member 11 and the bottom wall 31 when the movable cutting member 2 rotates. The waste is driven by the rotating lower movable blade 22 to pass through the gap between the fixed blade 11 and the bottom wall 31, and is sheared and crushed in the gap between the lower movable blade 22 and the fixed blade 11 and the gap between the lower movable blade 22 and the bottom wall 31.

[0034] A raised rib 33 is provided on the bottom wall 31 below the fixed blade part 11. The lower surface of the lower movable blade part 22 passes through the raised rib 33 when the movable cutting member 2 rotates. The raised rib 33 is V-shaped. The design of the raised rib 33 can intercept debris and increase friction with the lower movable blade part 22, thereby grinding and crushing the debris.
