[0034] The above grinding ring 4 is prior art, which is arranged in the grinding cavity 30, fixed relative to the position of the grinding cover 3, and located below the feeding port 30a and above the discharging port 30b. ​

[0035] The grinding structure comprises a grinding disc 1 and a driving mechanism 2. The grinding disc 1 is located in the grinding cavity 30 and the inner periphery of the grinding ring 4, and can rotate around its own axis extending upward and downward relative to the grinding ring 4 under the driving of the driving mechanism 2. Meanwhile, a plurality of radially outward extending grinding teeth 10 are circumferentially spaced on the periphery of the grinding disc 1. The cross section of each grinding tooth 10 is isosceles trapezoidal, the upper base and the two waists of the isosceles trapezoid correspond to the upper surface of the grinding tooth 10, so that the upper surface of the grinding tooth 10 is a non-smooth surface with edges, and the lower base of the isosceles trapezoid corresponds to the lower surface of the grinding tooth 10.

[0036] Meanwhile, the upper surface of each grinding tooth 10 is spaced with two protrusions 11 in the inner and outer directions, each protrusion 11 extends around the extension direction of the grinding tooth 10, and a notch 110 is formed between the two adjacent protrusions 11. The outer side surface of the protrusion 11 on the outer side is arranged on the outer end surface of the grinding tooth 10 on which the protrusion 11 is located, and a step 12 is formed between the two. In this embodiment, the upper surface of the protrusion 11 is a non-smooth surface with edges, and the upper surface has a planar portion 111 extending along the tangent direction of the corresponding grinding disc 1, and inclined surface portions 112 extending downward and backward from both ends of the planar portion 111, and the lower side edges of the two inclined surface portions 112 extend downward and backward to engage with the lower surface of the grinding tooth 10. Meanwhile, as shown in the figure, the extension length L1 of the planar portion 111 is greater than the length T1 of the upper base of the trapezoid, and the two inclined surface portions 112 are arranged corresponding to the two waists of the trapezoid. Figure 3

[0037] In this embodiment, the grinding tooth 10 with the protrusion 11 can better grind and crush the fish scale type kitchen garbage when the fish scale type kitchen garbage is squeezed and rubbed between the grinding tooth 10 and the grinding ring 4 due to the effect of the step 12 and the protrusion 11.

[0038] Meanwhile, for the long fiber type kitchen garbage, when such garbage enters between the grinding tooth 10 and the grinding ring 4, it is collected between the protrusion 11 and the notch 110, and the grinding disc rotates, the long fiber is pulled along the notch 110 between the two protrusions, so as to be cut off.

[0039] For general kitchen garbage, the design of the protrusion in this embodiment makes the garbage fragments stuck between the grinding disc and the grinding ring have a larger stress per unit area, so that they can be crushed more easily.
