A grinding blade 100 according to an embodiment of the first aspect of the present invention is described below with reference to fig. 1 to 11.

Referring to fig. 1 and 2, in some embodiments, a grinding blade 100 according to an embodiment of the first aspect of the present invention includes a connecting portion 101 at a center, a grinding portion 102 provided at an outer periphery of the connecting portion 101, and a plurality of spokes 103 for connecting the grinding portion 102 and the connecting portion 101. Wherein, the connecting part 101 is used for connecting with a driving shaft 902 of the food processor of the third aspect embodiment, the grinding part 102 is provided with a plurality of grinding teeth 201, the grinding teeth 201 are used for grinding in cooperation with a chassis 901 of the food processor of the third aspect embodiment, the spoke 103 is provided with a blade 104, and the blade 104 is arranged on the windward side of the rotation direction of the spoke 103. Between two adjacent spokes 103 openings 105 are formed allowing water flow between grinding teeth 201 and bottom disc 901.

During operation, the driving shaft 902 of the food processor drives the grinding tool 100 to rotate, and the cutting edges 104 of the spokes 103 cut food, so that the food is further refined, and subsequent grinding is facilitated. The refined food and water enter the area between the grinding part 102 and the chassis 901 along the opening 105 between two adjacent spokes 103 for grinding, and the food is crushed, so that the effective ingredients in the cell walls of the food can be fully exposed, the release speed and the release amount of the plant effective ingredients are greatly improved, and the absorption speed and the absorption amount of a human body can be improved.

Since the grinding can be performed at a lower rotation speed, the rotation speed can be reduced by grinding the grinding cutter 100 of the present embodiment, thereby effectively reducing the working noise. In addition, the spokes 103 have a connecting function and also have a function of pressing water downwards, so that the refined food and water are accelerated to enter the area between the grinding part 102 and the base plate 901 for grinding, and the working efficiency of grinding is improved.

It should be noted that, in some other embodiments, the grinding part 102 may also be provided with a plurality of protrusions, instead of the grinding teeth 201, and the grinding is performed by the protrusions on the grinding part 102 matching with the cup body of the food processor.

Referring to fig. 1 and 2, in some embodiments, the abrasive section 102 is annular and a plurality of spokes 103 are circumferentially spaced. The grinding part 102 is annular, so that food can be continuously ground, fine grinding of the food can be ensured, and the grinding effect is improved.

Referring to fig. 3, in some embodiments, the plurality of grinding teeth 201 are arranged in a staggered manner in a radial direction, and more specifically, the density of the plurality of grinding teeth 201 increases in a direction away from the connection portion 101. That is, the larger the radius from the connecting portion 101, the larger the number of grinding teeth 201 on the grinding portion 102. Due to the centrifugal force, food diffuses from the center (namely, the connecting part 101) to the periphery, and in the diffusion process, as the number of teeth of the grinding teeth 201 becomes larger, the food is more finely ground, so that the process from semi-fine grinding to fine grinding is realized, the grinding resistance is favorably reduced, the smoothness of the grinding process is ensured, and the grinding quality is ensured.

With continued reference to fig. 3, in some embodiments, the grinding section 102 is provided with a flow passage 301, the flow passage 301 being disposed between two grinding teeth 201.

Meanwhile, the first blade 401 is matched with the spoke 103, so that the water passing through the grinding teeth 201 is increased, and the grinding efficiency is improved.

In some embodiments, the first blade 401 is disposed between two adjacent spokes 103, and the first blade 401 may cooperate with the spokes 103 to cut food in a staggered manner, so that the food is more fully refined and the cutting efficiency is improved. In addition, the first blade 401 is disposed between two adjacent spokes 103, so that the first blade 401 can directly press water toward the opening 105 between the two spokes 103, thereby effectively increasing the water passing amount through the grinding teeth 201, and further improving the grinding efficiency.

In some embodiments, the first blade 401 is higher than the spokes 103, the first blade 401 may more conveniently cut food and help the first blade 401 to press water downward so that the cut food and water enter the area between the grinding part 102 and the bottom plate 901 to be ground along the opening 105 between two adjacent spokes 103.
