A plurality of main grinding ring teeth 23 are uniformly distributed on the lower edge of the main grinding ring 20, and the main grinding ring teeth 23 are staggered and intersected with the auxiliary grinding ring teeth 31.

As shown in fig. 1, the first grinding module includes a fixed cutter head 12 and a main grinding ring 20, and a first grinding gap is formed between the fixed cutter head 11 and the main grinding ring 20. Two tangent angles 111 are arranged on two straight line edges of the fixed cutter head 12, and the two tangent angles 111 are rotationally symmetrical by taking the axis of the grinding disc 10 as a center. The purpose of the chamfer 111 is to increase the grinding effect.

The second grinding module comprises a rotary cutter head 12 and a projection 21 arranged on the inner wall of the main grinding ring 20, preferably, the projection 21 is positioned on the upper part of the inner wall of the main grinding ring 20 (i.e. the upper part of the inner circular surface of the main grinding ring 20). The rotary cutter head 12 is rotatably mounted on the grinding disc 10, and more specifically, the free end of the rotary cutter head 12 is disposed below the protrusion 21, and the fixed end of the rotary cutter head 12 is rotatably connected to the grinding disc 10 (the rotary cutter head 12 can freely rotate 360 degrees). Thus, during operation of the grinding mechanism, relative movement between the projection 21 and the rotary cutter head 12 is enabled. A second grinding gap is formed between the rotary cutter head 12 and the projection 21. Preferably, the number of the rotating tool bits 12 is two, and the two rotating tool bits 12 are symmetrical about the axial center of the grinding disk 10.

Preferably, in the present embodiment, four air guiding openings 14 are provided. As shown in fig. 3, when the grinding mechanism is operated, the grinding plate 10 rotates, and a pressure difference is formed between the upper side and the lower side of the grinding plate 10 based on the arrangement of the air guide opening 14, that is, the pressure above the grinding plate 10 is large, and the pressure below the grinding plate 10 is small, so that the food waste above the grinding plate 10 can be better discharged to the lower side of the grinding plate 10, and then discharged from the waste outlet 40.

In order to allow water to be discharged in time, a plurality of water discharge holes 15 are provided on the abrasive disk 10.

To enable better positioning and mounting of the secondary grinding ring 30. The auxiliary grinding ring 30 is provided with two positioning blocks 32, and the two positioning blocks 32 are rotationally symmetrical around the axis of the auxiliary grinding ring 30. And a positioning groove 33 is arranged on the positioning block 32. The positioning slot 33 corresponds to two main grinding ring teeth 23 which are centrosymmetric on the main grinding ring 20. The auxiliary grinding ring 30 can be positioned and installed better by matching the positioning block 32 with the positioning groove 33.

In addition, the invention also provides the food waste disposer, which comprises the grinding mechanism as shown in fig. 3.

The working principle of the grinding mechanism is briefly explained below: after the food waste enters the grinding mechanism, the grinding disc 10 is driven by the motor to rotate anticlockwise (3000r/min-4000 r/min). The food-trash is first ground by a first grinding module consisting of the fixed cutter head 12 and the main grinding ring 20, which can grind the food-trash into smaller pieces. Thereafter, the food waste pieces are thrown against the edge of the grinding disk 10 based on the centrifugal force generated by the rotation of the grinding disk 10. The pieces of food-trash located at the edge will be ground a second time by the second grinding module consisting of the rotating cutter head 12 and the lugs 21, and since the second grinding gap is smaller than the first grinding gap, the food-trash subjected to the second grinding is smaller in particle size than the food-trash subjected to the first grinding. At the same time, the third grinding module, consisting of the rotating cutter head 12 and the grinding teeth 22, grinds the food waste a third time, forming smaller waste particles. The food waste then enters a fourth grinding module consisting of the edge of the grinding plate 10 and the grinding teeth 22 for further grinding. And then enters a fifth grinding module consisting of the auxiliary grinding ring 30 and the cutter head teeth 13 for grinding. Through the five times of grinding, food waste particles with the particle size of less than 3mm can be formed, fiber plant waste can be effectively cut, vegetable and fruit shell plant waste can be processed into pulp, bone food waste can be processed into extremely small particles, and the refinement degree of the food waste is improved.

The preferred embodiments of the present invention have been described in detail, however, the present invention is not limited to the specific details of the above embodiments, and various simple modifications may be made to the technical solution of the present invention within the technical idea of the present invention, and these simple modifications are within the protective scope of the present invention.
