Detailed Description

The embodiment, refer to fig. 1 to 8, the structure is smashed to garbage disposer that this embodiment provided, it includes smashes blade 1, blade disc 2 and around setting up the circular filter screen 3 in blade disc 2 peripheral position, smash blade 1 and include rectangular lamellar body, the middle part level of this rectangular lamellar body extends and forms installation department 11, and the both ends symmetry of this rectangular lamellar body is buckled and is upwards extended with an inclination a slope and respectively form a cutter portion 12, and inclination a is 130 ~ 150 degrees, preferably 140 degrees for form between cutter portion 12 and the blade disc 2 and keep away the vacancy, avoid colliding with the grinding cutter piece and interfere. One side edge of the bottom surface of one of the two cutter portions 12 is chamfered to form a first cutting edge surface 121, and the other side edge of the bottom surface of the other cutter portion 12 is chamfered to form a second cutting edge surface 122. Preferably, the end of the cutting portion 12 is provided with a horizontal tangent plane 123 and a vertical tangent plane 124, and the horizontal tangent plane 123 and the vertical tangent plane 124 are combined to form a cutting tip 125, so that the kitchen waste can be cut and shredded more quickly after the cutting tip 125 is added, and the grinding speed is increased effectively.

The central point of blade disc 2 puts and is equipped with installation axle 4, the installation department 11 of grinding blade 1 is fixed install on the axle 4, and is concrete, the central point of installation department 11 puts and is equipped with mounting hole 111, and in this embodiment, the appearance profile of this mounting hole 111 is square, installation axle 4 is the square shaft, and mounting hole 111 cover is established on installation axle 4 to through the nut locking, the assembly is inseparable, avoids appearing the cooperation phenomenon of skidding. In other embodiments, the mounting hole 111 may have a circular profile and then be provided with a key slot, and the mounting shaft 4 is fitted into the mounting hole 111 through a shaft key.

Two rotating shafts 5 are symmetrically arranged on the cutter head 2 corresponding to the two sides of the grinding blade 1, and grinding blade blocks 6 are arranged on the rotating shafts 5. Specifically, grind on the sword piece 6 eccentric be equipped with the shaft hole 61 of 5 looks adaptations of pivot, establish on pivot 5 through shaft hole 61 movable sleeve, realize grinding the rotatable setting of sword piece 6 on pivot 5. For promoting the grinding effect, the outer side wall of the grinding cutter block 6 is provided with grinding teeth 62, and the vertex angle of the grinding teeth 62 is a right angle, so that the grinding effect of the garbage is further improved.

Be equipped with blade group on circular filter screen 3's the inner wall, refer to fig. 2, 6 and 7, blade group includes a plurality of first blades 31, second blade 32 and third blade 33, first blade 31, second blade 32 and third blade 33 with the perpendicular distance of blade disc 2 is inconsistent, promptly first blade 31, second blade 32 and third blade 33 are arranged according to follow order extremely down on the axial direction in proper order, form the height structure of breaking by mistake in the circumferential direction, can cooperate better grinding cutter block 6 to grind the surplus rubbish in kitchen. In this embodiment, the number of the first blades 31 is preferably four, the number of the second blades 32 is preferably two, and the number of the third blades 33 is preferably two, and both the first blades and the third blades are arranged on the inner wall of the circular filter screen 3 in a circle-center symmetry manner. In other embodiments, the number of the first, second and

third blades

31, 32, 33 may be set according to the desired grinding effect. Preferably, the second blade 32 is disposed between two adjacent first blades 31. The third blade 33 is disposed at a position between adjacent first blades 31. The first blades 31, the second blades 32 and the third blades 33 are arranged in a staggered mode in the circumferential direction and in a staggered mode in the axial direction, an all-dimensional blocking structure is formed, and the grinding cutter blocks 6 can be better matched for cutting and shredding garbage.

Preferably, referring to fig. 6, the first blade 31 and the third blade 33 are square in shape, that is, the long strip body with a square cross-sectional profile has sharp corners and good cutting and shredding effects. The second blade 32 is close to one end of the inner wall of the circular filter screen 3, the outer dimension is larger, and the other end is gradually reduced. The outline of the profile is conical when viewed from the side, and the overall structure has high strength. Specifically, referring to fig. 6 and 8, the outer wall of the second blade 32 is formed by sequentially connecting an arched curved surface 321, a lower inclined surface 322, a concave curved surface 323, and an upper inclined surface 324. When the grinding cutter block 6 rotates clockwise as seen in the drawing, the garbage is extruded, broken and arranged to the upper side and the lower side by the arched curved surface 321, and is cut and shredded by the first blade 31 and the third blade 33 at the rear side position. When the grinding cutter block 6 rotates counterclockwise, the garbage cut and shredded by the first blades 31 to the lower position thereof is cut and shredded by the upper inclined surface 324 and the garbage cut and shredded by the third blades 33 to the upper position thereof is cut and shredded by the lower inclined surface 322, respectively. The above process is repeated, thereby effectively reducing the occurrence of missing grinding objects or grinding dead corners and improving the grinding effect.

During production and manufacture, the square punch is used for punching the circular filter screen 3 to enable the inner wall of the circular filter screen to be turned up to form the first blade 31 and the third blade 33, and the conical punch is used for punching the circular filter screen 3 to enable the inner wall of the circular filter screen to be turned up to form the second blade 32. The process is simple and easy to realize, and the first blade 31, the second blade 32 and the third blade 33 are connected with the circular filter screen 3 into a whole, so that the connection is firm and the structural stability is good. In other embodiments, the first blade 31, the second blade 32 and the third blade 33 may be of a split structure, and then the connection may be fixed by welding or riveting.

When the garbage crusher works, the grinding blades 1 rotate along with the rotation of the cutter head 2 to cut and shred garbage in the circular filter screen 3, meanwhile, the grinding cutter block 6 can freely rotate by taking the rotating shaft 5 as an axis, and a grinding gap for grinding the garbage can be formed between the outer side wall of the grinding cutter block 6 and the inner wall of the circular filter screen 3. In action cooperation, the first blade 31, the second blade 32 and the third blade 33 in the blade group can alternately appear in the grinding gap, and the positions in the circumferential direction and the axial direction are constantly changed to form an all-dimensional blocking structure, in the actual grinding process, the kitchen garbage can be cut and torn quickly and efficiently through the matching of the grinding blade 1, the grinding cutter block 6 and the blade group on the inner wall of the circular filter screen 3, the occurrence of ground leakage or grinding dead corners is reduced, sufficient grinding is ensured, the grinding efficiency is high, and the garbage treatment effect is good.

Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should fall within the protection scope of the claims of the present invention. Furthermore, although specific terms are used herein, they are used for convenience of description and are not intended to limit the present invention in any way, and it is within the scope of the present invention to use other blades or devices that are the same or similar to the present invention.
