For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] As Figures 1-5 shown, the present invention provides a grinding assembly, which can be applied to a kitchen waste processor and is used to process kitchen waste by means of cutting, crushing, grinding, etc.

[0030] The grinding assembly of the present invention may include: a cutter head structure and an inner grinding ring 30. The cutter head structure includes a cutter head 10 and an outer grinding ring 20. The outer grinding ring 20 surrounds the periphery of the cutter head 10 and forms a grinding cavity with the cutter head 10.

[0031] The cutter head 10 can rotate around an axis. The cutter head 10 is disc-shaped and can have a mounting hole at its central position for mounting on the rotating shaft of the kitchen waste processor and rotating with the rotating shaft. The surface of the cutter head 10, such as the upper surface, can be provided with a plurality of crushing components. During the high-speed rotation of the cutter head 10, kitchen waste is processed by means of crushing, cutting, grinding, etc. by the crushing components.

[0032] The outer grinding ring 20 is arranged on the cutter head 10, forms a grinding cavity with the cutter head 10, and can rotate with the cutter head 10. The outer grinding ring 20 has a peripheral wall with upper and lower openings. The lower surface of the peripheral wall of the outer grinding ring can be fixed on the surface of the cutter head 10 to be basin-shaped, so that the peripheral wall of the outer grinding ring and the cutter head 20 form a grinding cavity with an upper opening. The outer grinding ring 20 can be welded or integrally formed with the cutter head 20. A plurality of grinding knives 21 protruding towards the grinding cavity are provided on the peripheral wall of the outer grinding ring 20 ( Figure 5 as shown) and a plurality of first discharge ports 22. The grinding knives 21 can be vertically arranged in the axial direction of the outer grinding ring 20 to form a vertical strip structure. Further, the height of the vertical strip structure can be the same as the height of the peripheral wall of the outer grinding ring 20, that is, the vertical strip-shaped grinding knives 21 extend vertically upward along the inner peripheral wall of the outer grinding ring 20. For example, four protruding vertical strip-shaped grinding knives 21 can be arranged along the inner wall of the outer grinding ring 20 and are equally spaced along the circumferential direction of the outer grinding ring 20. The plurality of first discharge ports 22 can be arranged at the bottom of the peripheral wall of the outer grinding ring 20 and penetrate its thickness direction (radial direction).

[0033] At least part of the inner grinding ring 30 is arranged in the grinding cavity. The grinding cavity is divided into an inner grinding cavity and an outer grinding cavity. There is a gap between the peripheral wall of the outer grinding ring 20 and the peripheral wall of the inner grinding ring 30, and this gap forms the outer grinding cavity. The grinding knives 21 are located in the gap. The inner grinding ring 30 can be fixed on the housing of the kitchen waste processor and is a fixed part, and the cutter head 10 is a movable part. The rotation of the cutter head 10 drives the outer grinding ring 20 to rotate relative to the inner grinding ring 30 together. The inner grinding ring 30 has a peripheral wall, and an annular bending part extending towards the radially outer side can be provided on the top surface (upper edge) of the peripheral wall of the inner grinding ring 30, and the inner grinding ring 30 is fixed in the housing through the annular bending part. The inner grinding ring 30 is nested inside the outer grinding ring 20, and an annular gap is formed between the inner grinding ring 30 and the outer grinding ring 20. A plurality of second discharge ports 31 corresponding to the positions of the first discharge ports 22 are also provided on the peripheral wall of the inner grinding ring 30. Preferably, the second discharge ports 31 are larger than the first discharge ports 22.

[0034] When the cutter head 10 and the outer grinding ring 20 rotate relative to the inner grinding ring 20 together, the kitchen waste is broken and cut by the crushing structure on the cutter head 10. The chopped kitchen waste is discharged from the second discharge port 31 of the inner grinding ring 30 under the action of the centrifugal force of the cutter head 20 and enters the annular gap formed between the inner grinding ring 30 and the outer grinding ring 20. The food residues in the annular gap are ground by the grinding knives 21 on the peripheral wall of the rotating outer grinding ring 20 in cooperation with the peripheral wall of the inner grinding ring 30 and the structure of the second discharge port 31 on the peripheral wall. Since the second discharge port 31 is larger than the first discharge port 22, a part of the smaller food residues after grinding are discharged through the first discharge port 22 on the outer grinding ring 20, and the other part of the larger food residues are pushed by the grinding knives 21 protruding in the gap towards the second discharge port 31 on the inner grinding ring 30 and squeezed back (pushed back) into the inner grinding ring 30, and then are further broken and ground by the crushing structure on the cutter head 10 again. In this way, the number of cutting and grinding times is increased reciprocally, the kitchen waste is completely pulverized, and the flexible long fiber waste can also be processed more thoroughly.

[0035] In some embodiments, the second discharge port 31 penetrates through the lower edge of the peripheral wall of the inner grinding ring 30 and has an opening facing the cutter head 10, such as a U-shaped discharge port. Correspondingly, the first discharge port 22 is located at the lower part of the peripheral wall of the outer grinding ring 20.

[0036] Furthermore, a plurality of third discharge ports 32 are also provided on the peripheral wall of the inner grinding ring 30, and the third discharge ports 32 are located above the second discharge port 31. The third discharge ports 32 can be circular holes and are arranged along the circumferential direction of the inner grinding ring 30. No discharge port is provided at the position on the peripheral wall of the outer grinding ring 30 corresponding to the third discharge port 32, so that the food residues discharged from the third discharge port 32 flow towards the annular gap formed between the inner grinding ring 30 and the outer grinding ring 20 through the shielding of the peripheral wall of the outer grinding ring 20, and thus are further ground by the grinding knives 21 on the inner peripheral wall of the outer grinding ring 20.

[0037] Furthermore, the second discharge port 31 and the third discharge ports 32 can be located in the grinding cavity to ensure that most of the food residues flowing out from the second discharge port 31 and the third discharge ports 32 flow towards the annular gap formed between the inner grinding ring 30 and the outer grinding ring 20.

[0038] In some embodiments, vertical strip-shaped holes 23 penetrating through the thickness direction of the peripheral wall of the outer grinding ring 20 are also provided on the peripheral wall of the outer grinding ring 20, and the vertical strip-shaped holes 23 are adjacent to the grinding knives 21. The width of the vertical strip-shaped holes 23 can be smaller than the width of the maximum opening position of the second discharge port 31.

[0039] In some embodiments, one or more breaker hammers 11 are provided on the cutter head 10. One end of the breaker hammer 11 close to the center of the cutter head 20 is hinged to the cutter head 10 and can swing relative to the cutter head 10 to break food residues. The breaker hammer 11 can swing relative to the cutter head 10 by using the centrifugal force when the cutter head 10 rotates, or can swing by using the impact of food on the breaker hammer 11 to crush food waste.

[0040] Further, one or more protruding vertical knives 33 can be provided on the inner peripheral wall of the inner grinding ring 30; a notch 111 is provided at one end of the breaker hammer 11 away from the center of the cutter head 10, and the notch is located below the vertical knife 33. In the state where the breaker hammer 11 swings relative to the cutter head 10, the notch 111 passes by the vertical knife 33 and cooperates with the vertical knife 33 to cut an object. On the one hand, the protruding vertical knife 33 cuts and punctures the food that is struck by the breaker hammer 11 onto the inner wall of the inner grinding ring 30, and on the other hand, it cooperates with the notch 111 at the front end of the breaker hammer 11 to cut and crush the food.

[0041] In some embodiments, a limiting component is further provided on the cutter head 10. The limiting component includes a first limiting convex block 14 and a second limiting convex block 15, which are used to limit the swinging stroke of the breaker hammer 11; a plurality of discharge holes 13 are also provided on the cutter head 10, and the discharge holes 13 are located within the swinging stroke area of the breaker hammer 11. In the circumferential direction of the cutter head 10, the first limiting convex block 14 and the second limiting convex block 15 are respectively located on both sides of the plurality of discharge holes 13. Among them, the first limiting convex block 14 can be close to the edge position of the cutter head 10, and the second limiting convex block 15 can be close to the center position of the cutter head 10.

[0042] The present invention also provides a kitchen waste processor, which includes a grinding assembly as described in any of the above embodiments.

[0043] The kitchen waste processor includes a housing, and the grinding assembly is arranged inside the housing. Among them, the inner grinding ring 30 is fixed on the housing, the cutter head 10 is installed on the rotating shaft of the kitchen waste processor, and the driving motor drives the rotating shaft to drive the cutter head 10 and the outer grinding ring 20 to rotate together.
