Detailed implementation manner

[0025] This detailed implementation manner is a grinding and stirring knife set of a kitchen waste processor, and its structural schematic diagram is as Figures 1 - 5 shown. This stirring knife set includes a cylinder body 1, a fixed knife 2, and a transmission shaft 3. The fixed knife 2 is fixedly connected to the inner wall of the cylinder body 1 through a first screw 4. The transmission shaft 3 is rotatably connected to the inner bottom of the cylinder body 1. The output end of the transmission shaft 3 is located inside the cylinder body 1 and is provided with a center block 6 through a second screw 5. The outer surface of the center block 6 is fixedly connected with a stirring knife 7 and a connecting rod 8. One end of the connecting rod 8 far from the center block 6 is fixedly connected with a turning knife 9. The fixed knife 2 cooperates with the stirring knife 7 and the turning knife 9 for cutting.

[0026] As Figure 3 and Figure 4 shown: In this embodiment, the stirring knife 7 gradually increases from the center block 6 to the outside. The outside of the stirring knife 7 is provided with a cutting opening 701 and a cutting groove 702, and the length of the cutting groove 702 is greater than the length of the cutting opening 701.

[0027] Such a setting forms a two-layer cutting edge by providing a cutting opening 701 and a cutting groove 702 on the outside of the stirring knife 7, so that the stirring knife 7 cooperates with the fixed knife 2 during rotation to achieve three-dimensional multi-layer cutting, thereby better crushing kitchen waste.

[0028] As Figure 1 and Figure 3 shown: In this embodiment, the fixed knife 2 includes a fixing plate 201. The top end of the fixing plate 201 is fixedly connected with a top plate 202. The bottom end of the fixing plate 201 is sequentially connected with a first bottom plate 203, a connecting plate 204, and a second bottom plate 205. Triangular spikes 206 are fixedly connected to the front and rear sides of the top plate 202, the first bottom plate 203, the connecting plate 204, and the second bottom plate 205. The top plate 202, the fixing plate 201, the first bottom plate 203, the connecting plate 204, and the second bottom plate 205 are a ninety-degree structure bent integrally, and the cutting groove 702 has the same shape as the first bottom plate 203, the connecting plate 204, and the second bottom plate 205.

[0029] By setting the fixed knife 2 in this way, with multiple triangular spikes 206 fixedly connected to the front and rear sides through multiple bends, the cooperation effect between the fixed knife 2 and the rotating stirring knife 7 and turning knife 9 is better. When rotating, the first bottom plate 203, connecting plate 204, and second bottom plate 205 pass through the cutting groove 702, enabling three-dimensional multi-layer cutting.

[0030] As Figure 4 and Figure 5 shown: In this embodiment, an installation groove is provided on the lower surface of the central block 6, and a groove 601 is provided on the upper surface of the central block 6. The top end of the transmission shaft 3 is located inside the installation groove, the second screw 5 is arranged inside the groove 601, and a silica gel cover 602 is further included. The silica gel cover 602 is installed in the groove 601 and covers the second screw 5.

[0031] By setting it in this way, the second screw 5 can be removed after long-term use, enabling the stirring knife 7 and the turning knife 9 to be removed for cleaning, thus making disassembly and cleaning more convenient. At the same time, the silica gel cover 602 provides anti-slip for the second screw 5, preventing internal water ingress and rusting, and improving the service life.

[0032] As Figure 2 and Figure 3 shown: In this embodiment, the turning knife 9 includes a horizontal plate 901 and a vertical plate 902 that cross each other. Blades 903 are formed at both the front and rear ends of the vertical plate 902. The top and bottom ends of the horizontal plate 901 are of the same size, and the vertical plate 902 gradually increases from the top to the bottom.

[0033] By setting the turning knife 9 in this way to have a cross structure with blades 903 formed on the front and rear sides, the turning knife 9 cooperates with the fixed knife 2 during rotation to achieve three-dimensional multi-layer cutting, thereby better crushing kitchen waste and improving the crushing efficiency.

[0034] Working principle: When in use, kitchen waste is placed in the cylinder 1, and an external motor drives the transmission shaft 3, stirring knife 7, and turning knife 9 to rotate. The stirring knife 7 and turning knife 9 cooperate with the fixed knife 2 during rotation to crush the waste. Since two-layer cutting edges are formed by providing a cutting opening 701 and a cutting groove 702 on the outer side of the stirring knife 7, the turning knife 9 has a cross structure with blades 903 formed on the front and rear sides, and the fixed knife 2 is bent multiple times with multiple triangular spikes 206 fixedly connected to the front and rear sides, enabling the stirring knife 7 and turning knife 9 to cooperate with the fixed knife 2 during rotation to achieve three-dimensional multi-layer cutting, thereby better crushing kitchen waste and improving the crushing efficiency. And the fixed knife 2 is fixed to the cylinder 1 through the first screw 4, and the stirring knife 7 and turning knife 9 are fixedly connected to the transmission shaft 3 through the central block 6 and the second screw 5. After long-term use, the first screw 4 and the second screw 5 can be removed, enabling the fixed knife 2, stirring knife 7, and turning knife 9 to be removed for cleaning, thus making disassembly and cleaning more convenient and preventing internal bacteria growth.

[0035] All the technical features in this embodiment can be freely combined according to actual needs.

[0036] The above embodiments are the preferred implementation solutions of the present utility model. In addition, the present utility model can also be implemented in other ways. Any obvious substitution without departing from the concept of the technical solution is within the protection scope of the present utility model.
