[0032] In the description of the present invention, it should be noted that the terms "inside", "outside", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0033] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "contacted", and "connected" should be understood in a broad sense, 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 ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] like Figure 1-Figure 7 As shown, the present invention provides a grinding component that can be used in a food waste disposer. It can effectively cut off difficult-to-clean garbage such as flexible long fibers, avoid the problem of flexible long fibers and other garbage objects agglomerating or entangled, and effectively prevent garbage from clogging the food waste disposer.

[0035] The grinding assembly may include a grinding ring 10 and a cutter head 20 .

[0036] The grinding ring 10 can be fixed in the housing of the food waste disposer and can be in the shape of a basin with a peripheral wall having upper and lower openings.

[0037] The cutter disc 20 is disposed in the grinding ring 10 and can rotate relative to the grinding ring. The cutter disc 20 can be connected to the drive motor of the food waste disposer, and the drive motor drives the cutter disc 20 to rotate relative to the grinding ring. For example, a mounting hole 29 is opened in the center of the cutter disc 20, and the cutter disc 20 is mounted on the drive shaft of the drive motor through the mounting hole 29.

[0038] A blade assembly is provided on the surface of the cutter disc 20, and the blade assembly can shear the garbage. The blade assembly can include a first blade 21 and a second blade 22, and the first blade 21 and the second blade 22 are staggered in the axial direction of the cutter disc, that is, the first blade 21 and the second blade 22 have different heights to the surface of the cutter disc 20, for example, the first blade 21 is slightly higher than the second blade 22, and the first blade 21 and the second blade 22 can be connected by stepped studs 24 of different heights, so that the first blade 21 and the second blade 22 are staggered in the axial direction of the cutter disc 20.

[0039] The first blade 21 is provided with a first blade 23 at its periphery, and the second blade 22 is provided with a second blade 23 at its periphery, and the first blade 21 and / or the second blade 22 can rotate relative to the cutter disc 20 under the action of an external force, so that the first blade 23 on the first blade 21 and the second blade 22 arranged in a staggered manner cooperate to cut the object to be cut. During the rotation of the first blade 21 and / or the second blade 22 relative to the cutter disc 20 under the action of an external force, the first blade 21 and the second blade 22 can partially overlap in the axial direction of the cutter disc 20 so that the first blade 21 and the second blade 22 form an up-and-down staggered posture, so that the first blade 23 on the first blade 21 and the second blade 22 cooperate to shear the object to be cut. The first blade 21 and / or the second blade 22 can rotate relative to the cutter disc 20 under the action of an external force, wherein the external force can be the impact force formed by the centrifugal force generated by the rotation of the cutter disc 20 causing the kitchen waste to collide with the first blade 21 and / or the second blade 22, and the impact force causes the first blade 21 and / or the second blade 22 to rotate relative to the cutter disc 20. The external force may also be a force actively applied to the first blade 21 and / or the second blade 22, for example, by directly driving the first blade 21 and / or the second blade 22 to rotate through a driving motor.

[0040] The grinding assembly of the present invention is provided with a first blade 21 and a second blade 22 on the cutter disc 20. During the rotation of the cutter disc 20 relative to the grinding ring 10, the first blade 21 and the second blade 22 can form a staggered posture in the axial direction of the cutter disc 20, and the first blade on the first blade 21 and the second blade on the second blade 22 cooperate to shear off garbage such as flexible fibers, so that garbage such as flexible long fibers can be effectively processed, and problems such as flexible long fibers and other garbage objects being avoided from agglomerating or entangled can be avoided, thereby effectively preventing garbage from clogging the food waste disposer.

[0041] In some embodiments, the first blade 23 and / or the second blade include a plurality of serrated portions distributed along the circumferential outer edge of the first blade 21 and / or the second blade 22. That is, a plurality of serrated first blades 23 may be provided along the circumferential outer edge of the first blade 21 and / or the second blade 22. The specific cross-sectional shape of the serrated portion may be, for example, an arc, a triangle, a trapezoid, a cone or an irregular shape. The overall shape of the first blade 21 and / or the second blade 22 may be an elongated strip, an ellipse, a circle or an irregular shape, and the outer contour (peripheral edge) size is increased by these shapes so that more blades may be provided on the outer contour, so that when shearing is performed, the effective engagement length will be increased, thereby improving the shearing efficiency.

[0042] In some embodiments, a breaker hammer assembly is further provided on the disc surface of the cutter disc 20, and the breaker hammer assembly includes a breaker hammer 25 and a protrusion 26. The breaker hammer 25 can swing along the circumference of the cutter disc 20, and the protrusion 26 is located on the swinging path of the breaker hammer 25. The bottom surface of the breaker hammer 25 is provided with a guide groove 252 ( Figure 5 As shown in the figure, the protrusion 26 is embedded in the guide groove 252. The protrusion 26 is arc-shaped and meshes with the groove of the breaker hammer. The breaker hammer is always meshed with the protrusion during the collision movement, and the breaker hammer and the protrusion form a shearing effect to shear the food waste. At the same time, the protrusion also guides the swing of the breaker hammer 25. Specifically, the end of the breaker hammer 25 close to the center of the cutter disc 20 is rotatably set on the cutter disc 20 through a screw, and the end away from the center of the cutter disc 20 is a free end. The breaker hammer 25 swings along the circumference of the cutter disc 20 with the screw as the axis to hit the garbage and crush the garbage, and forms a shearing effect on the food waste through the movement process of the breaker hammer and the cooperation with the protrusion. In order to better achieve the effect of impacting and crushing the garbage, in one example, a plurality of knocking ridges 251 are provided on at least one peripheral edge of the breaker hammer 25, and a plurality of sharp blades are formed by knocking the ridges 251 to better achieve the effect of impacting and crushing the garbage.

[0043] Furthermore, a third blade 261 is provided on the top surface of the protrusion 26 for cutting garbage. The third blade 261 may be in a 90° cone shape, with the cone tip facing upward. During the rotation of the cutter disc 20, the third blade 261 itself cuts the garbage, and forms a shearing effect on the food garbage in cooperation with the protrusion during the swinging process of the breaker.

[0044] The present invention uses the breaker 25 to impact and crush the food waste, and the breaker 25 cooperates with the protrusion 26 to shear the food waste during the swing process. Furthermore, the rotation of the cutter disc 20 causes the blade on the top of the protrusion 26 to cut the food.

[0045] Furthermore, a plurality of protrusions 26 are provided, and the plurality of protrusions 26 are arranged at intervals along the circumference of the blade disc 20. The plurality of protrusions 26 are arranged at intervals, forming a plurality of third blades for cutting food and cooperating with the swinging process of the breaker 25 to form shearing force and cutting action at multiple positions in the circumference.

[0046] Furthermore, the protrusions 26 may be provided in two or more groups, each group including a plurality of protrusions spaced apart along the circumference of the cutter disc, and the two or more groups of protrusions are arranged in the radial direction of the cutter disc. For example, two rows of protrusions 26 may be provided in the radial direction of the cutter disc 20, forming a plurality of third blades for cutting food and cooperating with the swinging process of the breaker 25 to form shearing forces and cutting effects at multiple radial positions.

[0047] In some examples, the breaker hammer assembly further includes a limiting convex portion provided on the disc surface of the cutter disc 20, which is used to limit the swing stroke of the breaker hammer, and the limiting convex portion includes a first limiting convex portion 271 and a second limiting convex portion 272. In the circumferential direction of the cutter disc 20, the first limiting convex portion 271 and the second limiting convex portion 272 are respectively located on both sides of the breaker hammer 25, and the first limiting convex portion 271 is far away from the center of the cutter disc 20, and the second limiting convex portion 272 is close to the center of the cutter disc 20. The first limiting convex portion 271 and the second limiting convex portion 272 respectively limit the swing of the breaker hammer 25 in the circumferential direction of the cutter disc 20, wherein the first limiting convex portion 271 is far away from the center of the cutter disc 20, and the second limiting convex portion 272 is close to the center of the cutter disc 20, so that the first limiting convex portion 271 and the second limiting convex portion 272 are not on the same circumference, so as to avoid food waste and make the movement space of food waste wider, so as to more fully crush and cut waste.

[0048] In some examples, two groups of breaker hammer assemblies are provided, and the two groups of breaker hammer assemblies are symmetrically arranged relative to the center of the cutter disc, and in the circumferential direction of the cutter disc 20, the blade assembly is located between the two groups of breaker hammer assemblies.

[0049] Furthermore, one or more vertical knives 28 are arranged on the surface of the cutter disc 20. In the circumferential direction of the cutter disc 20, the vertical knives 28 are located between the two groups of breaker hammer assemblies, and the vertical knives 28 and the blade assembly are located on opposite sides of the center of the cutter disc 20. The vertical knives 28 can pierce and cut the food waste, and the vertical knives 28 and the blade assembly are located on opposite sides of the center of the cutter disc 20, so that the food waste can be ground and crushed more fully.

[0050] In some embodiments, the periphery of the cutter disc 20 is provided with cutting teeth 201 arranged along its circumference; the grinding ring 10 is provided with one or more cutting blades 11 extending radially inwardly thereof, and in the axial direction of the cutter disc 10, the cutting blades 11 and the cutting teeth 201 are arranged alternately (up and down alternately), and when the cutter disc 20 rotates relative to the grinding ring 10, the cutting blades 11 cooperate with the cutting teeth 201 to cut the cut object. The cutting blades 11 cooperate with the cutting teeth 201 to further grind the crushed food, thereby improving the efficiency of food waste treatment.

[0051] Furthermore, at least one side of the cutting blade 11 has a fourth blade 12, and the angle between the surface of the fourth blade 12 and the surface of the blade disc 20 is an acute angle, so that the fourth blade 12 on the side of the cutting blade 11 is sharper, so that the cutting blade 11 cooperates better with the blade disc 20 and crushes food more fully.

[0052] There are more than two groups of cutting blades 11, and the two or more groups of cutting blades 11 are symmetrically arranged relative to the center of the grinding ring 10 to improve the efficiency of processing food waste.

[0053] The present invention also provides a food waste disposer, comprising: a grinding assembly as described in any of the above embodiments. Specifically, the food waste disposer further comprises: a housing and a motor disposed in the housing. The grinding assembly is disposed in the housing, and the grinding ring 10 is fixed to the housing; the driving shaft of the motor is connected to the cutter disc 20, and is used to drive the cutter disc 20 to rotate relative to the grinding ring 10.

[0054] During the rotation of the cutter disc 20 relative to the grinding ring 10, the kitchen waste moves due to the centrifugal force of the high-speed rotation of the cutter disc 20, and the food waste hits the first blade 21 and / or the second blade 21 on the cutter disc 20, so that the first blade 21 and / or the second blade 22 rotate relative to the cutter disc 20. Since the first blade 21 is staggered up and down, during the rotation of the first blade 21 and / or the second blade 22 relative to the cutter disc 20, the first blade 21 and the second blade 22 overlap and cooperate to shear and cut the food waste such as flexible fibers. At the same time, the reciprocating swing of the breaker 25 hits the food waste, and the protrusion 26 guides the breaker 25, which is conducive to the cutting effect of the second blade 261 on the top. Furthermore, the food is pierced and cut by the vertical knife. Therefore, after the food is hit, sheared, pierced and other multiple processes, the food residue is further ground and crushed by the cutting teeth 201 on the cutter disc 20 and the cutting blade 11, and the food waste is fully processed and discharged.
