The fixed reamer 2 includes an obliquely connected fixed plate 22 and a first blade 21, wherein the fixed plate 22 is attached to the inner wall of the storage cylinder 1 and is fixedly connected to the storage cylinder 1 by bolts 5, the first blade 21 is close to the bottom of the storage cylinder 1, at least part of the first blade 21 is parallel to the bottom of the storage cylinder 1, and the first blade 21 is in a bent shape to match the shape of the movable reamer 3, so as to form effective stir-frying and cutting for the kitchen waste in the storage cylinder 1, and the bent shape, compared with the plate shape, expands the contact area with the kitchen waste and accelerates the grinding speed. As shown Figure 3As shown, the movable reamer 3 is connected to the accommodating cylinder 1 in rotation around the central axis of the accommodating cylinder 1. That is, the first end of the movable reamer 3 is located at the central axis of the accommodating cylinder 1, and the second end is close to the inner wall of the accommodating cylinder 1. During the rotation, the second end of the movable reamer 3 rotates around the central axis at the first end. The rotation space of the movable reamer 3 is spaced apart from the first blade 21, that is, during the rotation of the movable reamer 3, along the axial Z direction of the accommodating cylinder 1, the movable reamer 3 is located below and / or above the first blade 21, and the shear force is formed by the rotation of the movable reamer 3 and the fixed first blade 21, which is used to cut kitchen waste.

Figures 1 to 3 As shown, a groove 311, i.e., an assembly notch, is provided on the side of the movable reamer 3 facing the bottom of the accommodating cylinder 1, i.e., the lower side of the movable reamer 3. A boss 11 corresponding to the groove 311 is provided at the bottom of the accommodating cylinder 1, i.e., the shape of the boss 11 is consistent with the shape of the groove 311, and the size of the boss 11 is slightly smaller than the size of the groove 311, so that when the movable reamer 3 rotates to cover the boss 11, the boss 11 is embedded in the groove 311, the boss 11 and the groove 311 cooperate with each other, and a certain movable gap is formed between the boss 11 and the groove 311 to prevent the boss 11 from interfering with the rotation of the movable reamer 3. During the stirring process, the kitchen waste at the bottom of the accommodating cylinder 1 will be lifted up by the boss 11, and when the movable reamer 3 rotates to the boss 11, the kitchen waste here will be effectively turned over and stirred to prevent the waste from sticking to the pot, especially sinking to the bottom and sticking to the bottom of the accommodating cylinder 1.

[0036] The kitchen waste disposer provided by the embodiment of the utility model has a plurality of first sawtooth-shaped notches arranged on the side wall of the fixed reamer, which can increase the cutting and grinding capacity of the kitchen waste, and avoid the problem that the kitchen waste rolls over at the reamer position and cannot be crushed.

The groove 311 is located on the lower side of the first movable reamer 31. In addition, during the working process, the driving mechanism 4 drives the first movable reamer 31 and the second movable reamer 32 to rotate clockwise for a period of time, and then rotates counterclockwise for a period of time, so as to effectively flip the food waste in the storage cylinder 1, so as to facilitate the storage cylinder 1 to evenly heat the food waste.

[0039] Optionally, refer to Figures 1 to 3 , the other end of the second movable reamer 32 is provided with a protruding scraper 321, and the scraper 321 is attached to the inner wall of the accommodating tube 1;

[0040] The surface of the scraper 321 is arc-shaped, and the curvature of the arc is the same as the curvature of the inner wall of the accommodating tube 1;

[0041] The distance between the scraper 321 and the bottom of the accommodating tube 1 is a1, the depth of the accommodating tube 1 is a2, and 0.5·a2≤a1.

[0042] Specifically, if Figures 1 to 3 As shown, a protruding scraper 321, i.e., a sidewall scraper, is disposed at the other end of the second movable reamer 32. The scraper 321 is attached to the inner wall of the accommodating tube 1 and is disposed parallel to the inner wall of the accommodating tube 1. The shape of the surface of the scraper 321 is consistent with the shape of the inner wall of the accommodating tube 1, i.e., an arc shape, so that the curvature of the arc surface of the scraper 321 is the same as the curvature of the inner wall of the accommodating tube 1, so as to improve the fit of the scraper 321. During the garbage crushing process, the garbage remaining on the inner wall of the accommodating tube 1 can be scraped off to the maximum extent, and the garbage can be prevented from adhering to the inner wall of the accommodating tube 1.

[0045] Specifically, if Figures 1 to 3 As shown, the fixed reamer 2 includes a first blade 21, a fixed plate 22 and a second blade 23 which are integrally connected. The fixed plate 22 is fixedly connected to the inner wall of the accommodating tube 1. Along the Z direction, the first blade 21 is located at the lower side of the fixed plate 22 and is called the fixed reamer lower blade, and the second blade 23 is located at the upper side of the fixed plate 22 and is called the fixed reamer upper blade. Along the Z direction, the first movable reamer 31 is located between the first blade 21 and the bottom of the accommodating tube 1, and the second movable reamer 32 is located between the first blade 21 and the second blade 23. The second blade 23 is plate-shaped and parallel to the bottom of the accommodating tube 1. During the stirring process, if a larger piece of food such as potatoes or onions is encountered, the larger piece of food is easily confined to the lower part of the second blade 23 under the restriction of the second blade 23.

That is, the gap between the first blade 21 and the movable reamer 3 is uniform and fine, and the value of the distance c in this embodiment is 2mm. During the mixing process, there is a uniform and consistent gap between the first blade 21 and the movable reamer 3, and the garbage in various places is mixed and cut into fine particles. If this distance value is too small, the extrusion force on the movable reamer 3 during the rotation process will increase, and it is easy to get stuck. If this distance value is too large, the gap is too large, so that the particles of the ground food residues are not fine enough.
