The thrust bearing 26 is arranged in the middle of the cutter disc 23, and the output shaft 221 of the motor 22 penetrates through the thrust bearing 26, so that the output shaft 221 and the cutter disc 23 can rotate relatively. The thrust bearing 26 includes a bearing main body 261, a bearing lower cover 262 disposed below the bearing main body 261, and a bearing upper cover 263 disposed above the bearing main body 261. The top surface of the bearing upper cover 263 of the thrust bearing 26 is slightly higher than the top surface of the cutter head 23, and the cutting member 24 is pressed against the thrust bearing 26. The cutter member 24 includes a cutter rest 241 in the middle and blades 242 attached to both sides of the blade attachment portion 241, and the cutter rest 241 has a circular shape having a diameter corresponding to that of the thrust bearing 26 and is pressed against the bearing upper cover 263 of the thrust bearing 26. The arrangement of the thrust bearing 26 can control the concentricity and the coaxiality of the output shaft 221 of the motor 22, and avoid the left-right shaking of the cutter disc 23 and the cutting piece 24 to influence the cutting effect. The blades 242 extend from the outer periphery of the holder 241 in directions away from each other symmetrically. The side (two and opposite) of each blade 242 extending from the outer periphery of the rest 241 progressively away from the rest 241 has a first blade edge 2421 at the bottom end and a second blade edge 2422 at the top end, see fig. 7.

Referring to fig. 4 to 6 and 8, the stirring member 25 includes a blade shaft 251 in the middle and a first blade 252 provided outside the blade shaft 251, and the stirring member 25 partially extends upward into the slag basket 1. The blade shaft 251 has a hollow cylindrical shape, and abuts against the top of the holder 241 of the cutter 24, and the output shaft 221 of the motor 22 is inserted into and connected to the blade shaft 251. The top of the output shaft 221 of the motor 22 can be penetrated with a screw, so that the output shaft 221 is connected with the stirring piece 25, the cutting piece 24 can be tightly pressed with the cutter disc 23, and the cutting piece 24 is prevented from moving up and down relative to the cutter disc 23. The first blades 252 may have two, are provided on the outer circumferential wall of the blade shaft 251, and are symmetrically arranged.

Referring to fig. 9, the cutter head 23 includes a circular cutter head body 231, a boss 232 provided at a near edge of the cutter head body 231, a first leak hole 233 provided in the cutter head body 231, and a screw hole 234. Since the output shaft 221 of the motor 22 passes upward through the cutter head body 231, the cutter deck 241, and the vane shaft 251, the cutter deck 241, the vane shaft 251, and the cutter head body 231 are coaxially disposed, and the center of the cutter deck 241 and the center of the cutter head body 231 are located on the same vertical line. The thrust bearing 26 is provided in the middle of the cutter head main body 231.

The bosses 232 may be four, circumferentially spaced on the cutterhead body 231, with each boss 232 extending upwardly a distance from the upper surface of the cutterhead body 231. The distance from the outer end of the blade 242 of the cutter 24 away from the cutter platform 241 to the center of the cutter platform 241 is smaller than the distance from the inner side surface of the boss 232 to the center of the cutter head body 231, so that when the cutter 24 rotates and the blade 242 rotates to be opposite to the boss 232, the outer end of the blade 242 is positioned radially inside the boss 232 with a certain interval therebetween, so that food residues can be cut in the interval. The first orifice 233 has a plurality of, in this embodiment, triangular shapes. The cutter head main body 231 is further provided with a leakage groove 235, and the leakage groove 235 is formed by downward sinking of the upper surface of the cutter head main body 231. In the present embodiment, the leakage grooves 235 may have four shapes and each of the four shapes is a long strip shape, each leakage groove 235 is arranged along the radial direction of the cutter head main body 231, and the four leakage grooves 235 are uniformly arranged at intervals in the circumferential direction. A second leak 2351 is provided in each leak groove 235.

The screw hole 234 can be provided with a grub screw for connecting and fixing the cutter disc 23 and the volute 27, and the grub screw ensures that the screw head is flush with the upper surface of the cutter disc 231, so as to avoid the blade 242 from being touched and damaged.

Referring to fig. 10, the impeller 21 includes a plurality of second vanes 211, a top of the second vanes 211 is spaced apart from the cutter head body 231, and each second vane 211 is provided with a third cutting edge 212 near the top of the cutter head body 231, thereby performing a cutting function while performing a function of accelerating the outflow of water.

When the food waste is treated and the food waste leaks out of the slag basket 1 into the waste crushing assembly 2, the motor 22 drives the impeller 21, the cutting member 24 and the stirring member 25 to rotate along the first direction (anticlockwise in the embodiment), the food waste with larger size is crushed by the friction between the first blade edge 2421 of the blade 242 of the cutting member 24 and the cutter head main body 231 of the cutter head 23, the residues are leaked below the cutter disc 23 through the first leakage holes 233, and in addition, shearing force is also generated between the second cutting edges 2422 of the blades 242 and the top of the lug bosses 232 on the cutter disc 23 to shear the residues, the shearing mainly aims at the residues with better toughness like the Chinese chives, whereby some of the strip-like debris that would otherwise impede agitation by the blades 242 is sheared off in the pockets 235 of the impeller 23, acting to prevent jamming of the blades 242, smaller residues in the leakage groove 235 can leak to the lower part of the cutter disc 23 through the second leakage hole 2351; meanwhile, the third blade 212 on the second blade 211 of the impeller 21 can also cooperate with the impeller 23 to cut the residues leaked between the impeller 23 and the impeller 21, so as to cut the residues into smaller pieces, and the cut residues are discharged from the volute 27 to the drain pipe, in the process, the first blade 242 of the stirring member 24 also has a certain cutting capability. The programming of motor 22 can have the protect function, and when motor 22 drove cutting member 24 and rotates, touch harder residue, when unable cutting this residue, can open the protection mode, output shaft 221 can clockwise rotation an angle, and anticlockwise rotation again avoids motor 22 to block motionless phenomenon.

When a large amount of food residues such as oil of chafing dish materials and the like remain in the residue basket 1 after the sink or the dish washer is used for a long time, the self-cleaning is started, at this time, the motor 22 is operated to drive the impeller 21, the cutting member 24 and the stirring member 25 to rotate in a second direction (clockwise in the embodiment) opposite to the first direction, the stirring member 25 stirs the water discharged from the sink 100 and then surges upwards, and the residue basket 1 forms water flow impact, so that the residues on the residue basket 1 are cleaned through the upward surging of the water flow.
