[0042] Further, such as Figure 4 , Figure 5 As shown, each first grinding tooth is arranged obliquely along the inner wall of the first grinding groove 1011, and the vertical projection of each first grinding tooth is a radially arranged straight line or arc.

[0043] In an optional embodiment of the present invention, Figure 4 , Figure 5As shown, the outer edge of the first grinding groove 1011 is provided with a circular boss along the circumference of the first grinding groove 1011, and a first extrusion surface 1012 is formed on the bottom surface of the boss, and a first grinding tooth ring 1013 is provided on the outer wall of the boss along the circumference of the boss; the grinding ring 1 also includes a second grinding tooth ring 102, the second grinding tooth ring 102 is a circular ring structure arranged along the horizontal direction, the second grinding tooth ring 102 is connected to the inner edge of the first grinding groove 1011 along the circumference of the first grinding groove 1011, and a plurality of axial cutting teeth 1021 are provided at the bottom of the second grinding tooth ring 102 along the circumference of the second grinding tooth ring 102, and the food waste entering the grinding chamber 6 will be cut and crushed by the axial cutting teeth 1021 on the second grinding tooth ring 102, thereby performing primary grinding on the food waste.

[0044] Further, such as Figures 3 to 5 As shown, a plurality of radial cutting teeth 1022 are arranged on the inner wall of the second grinding gear ring 102 at circumferential intervals along the second grinding gear ring 102, and adjacent radial cutting teeth 1022 are staggered in the vertical direction. The food waste in the grinding chamber 6 is synchronously cut by each radial cutting tooth 1022, thereby improving the crushing efficiency of the food waste.

[0045] Furthermore, the second grinding gear ring 102 and the grinding ring body 101 can be divided into two parts for fixed connection. Preferably, the second grinding gear ring 102 and the grinding ring body 101 are an integrally formed structure.

[0046] In an optional embodiment of the present invention, Figure 4 , Figure 5 As shown, a plurality of first vertical teeth 1014 are arranged at intervals at the bottom of the grinding ring body 101 and at the periphery of the first grinding groove 1011 , and each first vertical tooth 1014 is arranged in at least one annular pattern along the circumference of the grinding ring body 101 .

[0047] In an optional embodiment of the present invention, Figure 1 , Figures 6 to 8As shown, the grinding disc 2 includes a grinding disc body 201. The grinding disc body 201 is a disc-shaped structure arranged in the horizontal direction. A motor 5 is arranged below the grinding disc body 201. The output shaft of the motor 5 extends vertically upward. The center position of the grinding disc body 201 is fixedly sleeved on the output shaft of the motor 5. The second grinding groove 2011 is arranged at the top of the grinding disc body 201 along the circumference of the grinding disc body 201 and is opposite to the position of the first grinding groove 1011 in the vertical direction. The inner wall of the second grinding groove 2011 is a slope-shaped structure that gradually slopes downward from the outer edge close to the grinding disc body 201 to the outer edge away from the grinding disc body 201, so that a second acute angle β is formed between the longitudinal section of the second grinding groove 2011 and the horizontal direction. A plurality of second grinding teeth are continuously arranged in the grinding disc body 201 along the extension direction of the grinding disc body 201. When the grinding ring 1 and the grinding disc 2 are assembled, as shown in FIG. Figure 1 As shown, the first grinding groove 1011 is located above the second grinding groove 2011, and a second grinding space 8 is formed between the first grinding groove 1011 and the second grinding groove 2011, and a first grinding space 7 is formed above the grinding disc body 201 and is connected to the grinding cavity 6 located above the grinding ring body 101. The second grinding space 8 is connected to the first grinding space 7. After the food waste is primarily crushed and cut in the first grinding space 7, it enters the second grinding space 8 under the action of centrifugal force, and the first grinding teeth on the first grinding groove 1011 cooperate with the second grinding teeth on the second grinding groove 2011 to perform secondary crushing and grinding on the food waste.

[0048] Further, such as Figure 6 , Figure 8 As shown, each second grinding tooth is arranged obliquely along the inner wall of the second grinding groove 2011, and the vertical projection of each second grinding tooth is a radially arranged straight line or arc.

[0049] In an optional embodiment of the present invention, Figure 1 , Figure 6 , Figure 8As shown, the outer edge of the second grinding groove 2011 forms a second extrusion surface 2012 along the top surface of the grinding disc body 201 which is opposite to the first extrusion surface 1012 in the vertical direction, and a plurality of second vertical teeth 2014 are arranged at intervals on the top of the second extrusion surface 2012 and located at the outer periphery of the second grinding groove 2011. Each second vertical tooth 2014 is arranged in at least one ring along the circumference of the grinding disc body 201, and each second vertical tooth 2014 is staggered with each first vertical tooth 1014, and an extrusion gap for food waste to pass through is reserved between the first vertical tooth 1014 and each adjacent second vertical tooth 2014. A third grinding space 9 connected to the second grinding space 8 is formed between the first extrusion surface 1012 and the second extrusion surface 2012. A fourth grinding space 10 is formed below the grinding disc body 201. The third grinding space 9 is connected to the fourth grinding space 10. After passing through the first grinding groove 1011 and the second grinding groove 2011, the food waste enters the third grinding space 9 between the first extrusion surface 1012 and the second extrusion surface 2012 under the action of centrifugal force and extrusion force. The food waste is crushed and ground at the third level by the first vertical teeth 1014 and the second vertical teeth 2014 in the third grinding space 9.

[0050] Furthermore, the first extrusion surface 1012 and the second extrusion surface 2012 are respectively provided with fine convex teeth (not shown) or fine protrusions (not shown), so as to increase the roughness of the first extrusion surface 1012 and the second extrusion surface 2012, play a role of further grinding when the food waste passes through the third grinding space 9, and improve the grinding effect of the food waste.

[0051] In an optional embodiment of the present invention, Figure 6 , Figure 8 As shown, a plurality of cutting teeth 2013 and a plurality of grinding hammers 2015 are provided at the top of the grinding disc body 201 and on the inner side of the second grinding groove 2011 . After the food waste enters the first grinding space 7 , the food waste can be initially cut by the cutting teeth 2013 and the grinding hammers 2015 .

[0052] In an optional embodiment of the present invention, Figure 7 As shown, a plurality of water repellent sheets 2016 are disposed at the bottom of the grinding disc body 201. The water repellent sheets 2016 are thin sheet structures disposed in the vertical direction. During operation, each water repellent sheet 2016 rotates with the grinding disc body 201, thereby increasing the water flow pressure in the fourth grinding space 10, so that the water flow and the fully crushed food waste are quickly discharged from the drain port 401 of the food waste disposer.

[0053] The working principle of the multi-stage grinding structure of food waste is as follows: after the food waste disposer is started, the output shaft of the motor 5 drives the grinding disc 2 to rotate, and the food waste and water flow enter the first grinding space 7 through the water outlet 301 of the food waste disposer, and the food waste is crushed into smaller particles or fibers by the radial cutting teeth 1022, the axial cutting teeth 1021, the cutting convex teeth 2013 and the grinding hammer 2015 in sequence, and then the food waste is squeezed into the second grinding space 8 between the first grinding groove 1011 and the second grinding groove 2011 under the action of the centrifugal force generated by the rotation of the grinding disc 2, and continues to be ground by the first grinding teeth and the second grinding teeth. The food waste is ground into smaller particles and shorter fibers, and then enters the third grinding space 9 between the first extrusion surface 1012 and the second extrusion surface 2012 under the action of centrifugal force and extrusion force. In the third grinding space 9, the food waste is ground and sheared by the first grinding tooth ring 1013, the first vertical teeth 1014 and the second vertical teeth 2014. The particles, fibers and fluid mixture formed after sufficient grinding flow into the fourth grinding space 10 under the action of gravity and pressure, and the water flow is moved by the water-repellent sheet 2016 to form a boost pressure, so that the liquid and food waste are quickly discharged to the fourth grinding space 10 and flow into the sewer pipe.

[0054] The following is the specific working process of the multi-stage grinding structure of food waste: after the food waste disposer is started, the motor 5 rotates, and the output shaft of the motor 5 drives the grinding disc 2 to rotate. At this time, the cutting convex teeth 2013 on the top of the grinding disc 2 and the grinding hammers 2015 rotate together with the grinding disc 2. If the grinding hammer 2015 adopts a movable hammer head, the grinding hammer 2015 will swing along the direction of the centrifugal force with the rivet as the axis under the action of centrifugal force, and a gap needs to be reserved between the grinding hammer 2015 and the axial cutting teeth 1021 on the second grinding gear ring 102. The food waste enters the first grinding space 7 through the drain port 301 at the top of the food waste disposer, and is first cut into larger block particles by the cutting convex teeth 2013 and the grinding hammers 2015. The food waste after the primary cutting process is thrown to the second grinding gear ring 102 under the action of centrifugal force. At this time, the grinding hammers 2015 and the axial cutting teeth 1021 and the radial cutting teeth 1022 move relative to each other, thereby grinding and tearing the larger block particles into smaller particles. The diameter of the ground particles is smaller than the diameter between the two adjacent axial cutting teeth 1021. The gap can be squeezed into the second grinding space 8 between the first grinding groove 1011 and the second grinding groove 2011; after the food waste particles enter the second grinding space 8, under the action of the squeezing force and the centrifugal force, the food waste particles gradually move toward the outer edge of the second grinding space 8, and at the same time, because the longitudinal section of the first grinding groove 1011 and the longitudinal section of the second grinding groove 2011 respectively form an acute angle with the horizontal direction, the first grinding groove 1011 and the second grinding groove 2011 cooperate to form a conical grinding structure that contracts outward (that is, the first grinding groove 1011 is a conical grinding structure that contracts outward). The distance between the first extrusion surface 1011 and the second grinding groove 2011 gradually decreases from the inside to the outside), so that the food waste particles are continuously squeezed outward, and finally a small gap (i.e., the third grinding space 9) is formed between the first extrusion surface 1012 and the second extrusion surface 2012, thereby achieving finer grinding of the food waste particles; the food waste enters the third grinding space 9 under the action of centrifugal force and extrusion force, and in the third grinding space 9, the food waste is sheared and ground between the first grinding tooth ring 1013, the first vertical tooth 1014 and the second vertical tooth 2014, so that the food waste particles are further squeezed outward. The garbage particles are further refined, and the fibers in the food garbage particles can be further broken. Finally, the finely ground particles enter the fourth grinding space 10 under the action of centrifugal force, extrusion force and gravity. The multiple water-repellent plates 2016 at the bottom of the grinding disc 2 rotate synchronously with the grinding disc 2, thereby stirring the mixture of fully crushed food garbage particles and liquid to increase the rotation speed and centrifugal force of the mixed fluid, so that the mixture of food garbage particles and liquid can quickly flow out of the food garbage disposer through the drain port 401 under the action of water pressure and enter the sewer.

[0055] From the above description, it can be seen that the present invention achieves the following technical effects:

[0056] 1. The multi-stage grinding structure for food waste truly realizes the multi-stage grinding treatment of food waste. The food waste is graded and layered and ground in turn through the cutting convex teeth 2013, the grinding hammer 2015, the radial cutting teeth 1022, the axial cutting teeth 1021, the first grinding teeth, the second grinding teeth, the first grinding tooth ring 1013, the first vertical teeth 1014 and the second vertical teeth 2014. On the basis of not reducing the grinding efficiency, the grinding fineness is greatly improved to ensure that the food waste is fully ground and crushed, and the problem of sewer blockage caused by insufficient grinding of food waste is effectively reduced. The structure is suitable for large-scale promotion and use.

[0057] Second, the multi-stage grinding structure of food waste can process long-fiber food waste through multiple grinding, extrusion and cutting processes, so that the fiber length of the food waste is greatly reduced, solving the problem of long-fiber food waste being difficult to handle that has long plagued the food waste disposal industry, and bringing creative innovation to the food waste disposal industry.
