Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

First, the technical concept of the present invention will be explained.

As shown in fig. 1-3, a food processor in the prior art, such as a wall breaking machine, includes a main body 2 and a cup body assembly 1, wherein the cup body assembly 1 is detachably mounted above the main body 2, and a driving motor is disposed inside the main body 2. The food processor also comprises a crushing cutter component 11 which is arranged at the center of the cup body component 1 and is rotationally connected with the cup body component 1, and the crushing cutter component 11 is in transmission connection with a driving motor. Cup subassembly 1 includes cup 12, cup 13 and the blade disc subassembly 14 of setting between cup 12 and cup 13, in the normal use process, cup 12, cup 13 and blade disc subassembly 14 are non-detachable, cup 12 is used for holding and eats the material, cup 14 can guarantee that cup 12 remains stable when taking off, simultaneously also be used for being connected with host computer 2, blade disc subassembly 14 is used for fixed crushing cutter subassembly 11, blade disc subassembly 14 passes through cup 12 and 13 screw threads of cup or buckle locking, fix between cup 12 and cup 13.

As shown in fig. 3 and 4, in the prior art, the cutter head sealing member 15 is sleeved on the edge of the cutter head assembly 14 by one circle, the upper surface of the cutter head sealing member 15 is pressed by a bottom force F1 of the cup body 12, and the lower surface of the cutter head sealing member 15 is supported by a circle of platform F2 supporting force at the bottom of the cup seat 13, because the edge of the cutter head assembly 14 supported by the lower part of the cutter head sealing member 15 is of an elastic soft rubber structure, when the edge is acted by a force F1, the edge is compressed and deformed together, so that the bottom of the cup body 12 is hardly matched with the cutter head assembly 14 by one; in addition, because the cutter head sealing piece 15 is elastic after being locked, when the cup body 12 of the mixing cup is stressed to shake, a gap can be formed at any time when the bottom of the cup body 12 is in one-circle fit with the edge of the cutter head assembly 14. All the reasons can cause the hard food materials or the fish bones to be hidden in the gaps.

The cutter head assembly 14 sleeved with the cutter head sealing piece 15 is pressed on the step surface of the cup seat and then locked by the cup body 12. In order to ensure that the cutter head sealing piece 15 has the effects of shock absorption and noise reduction, a certain compression allowance is reserved for the cutter head sealing piece 15 on the premise of sealing without water leakage, so that a small crack H is always formed between the cutter head assembly 14 and the bottom surface of the cup body 12, the crack H value is larger than zero, unbalanced force acts on the cup body 12 during working, the crack H value of the bottom surface piece of the cutter head assembly 14 and the cup body 12 of the stirring cup can be large and small, and therefore when food materials such as fishbone are crushed, the un-crushed fishbone can be brought to the small crack H by vortex and inserted deeper, and the fishbone cannot be crushed fully.

Consider the problem among the prior art mainly lies in the adjustment of the elasticity surplus of blade disc sealing member 14, the utility model discloses specifically adopt following technical scheme:

example 1

As shown in fig. 5-7, in the food processor for preventing food material from being jammed disclosed in this embodiment, a cutter disc sealing member 15 made of food grade silicone material is provided at an outer edge of the cutter disc assembly 14, and the cup body 12 and the cup holder 13 fix the cutter disc assembly 14 by pressing the cutter disc sealing member 15. The impeller seal 15 includes an upper seal 1501 and a lower seal 1502, the upper seal 1501 being disposed between the cup 12 and the impeller assembly 14, and the lower seal 1502 being disposed between the cup holder 13 and the impeller assembly 14. In the state that the cup body 12 is in sealing pressure joint with the cutter disc assembly 15, the upper sealing piece 1501 has a first elastic margin which is used for buffering the vibration between the cup body 12 and the cutter disc assembly 14 and is used for ensuring the sealing between the cup body 12 and the cutter disc assembly 14 secondarily, and the lower sealing piece 1502 has a second elastic margin which is mainly used for keeping the sealing between the cutter disc assembly 14 and the cutter seat 13 and is used for buffering the vibration between the cutter disc assembly 14 and the cutter seat 13 secondarily. Since the cup body 12 has a relatively high center of gravity and the cup body 12 vibrates during operation of the food processor, the upper seal 1501 originally disposed between the cup body 12 and the impeller assembly 14 is further compressed, and thus the first elastic margin is set to be greater than the second elastic margin, so that the clearance between the cup body 12 and the impeller assembly 14 can approach zero when the upper seal 1501 is compressed again during operation of the food processor. In actual work in-process, cup 12 takes place to rock because of smashing cutter unit spare 11's high-speed rotation, the clearance between cup 12 and the last sealing member 1501 produces the change under for the out of operation state, the clearance variation is big time-wise little under the influence of rocking, edible material such as fish bone can be because here clearance open with closed in-process clamp tightly in the clearance the inside, be difficult for wasing, this embodiment reduces cutter head assembly 14 through the elasticity surplus that reduces sealing member 1502 down and rocks, thereby reduce the variation in clearance between cutter head assembly 14 and the cup 12, the clearance that moves between cutter head assembly 14 and the cup 12 is littleer, it is difficult for the card to go into in the clearance between cutter head assembly 14 and the cup 12 to make edible material such as fish bone.

It can be understood that, although the first elastic allowance is greater than the second elastic allowance in the technical scheme disclosed in this embodiment to avoid the food material from being jammed, in fact, the second elastic allowance may also be set to be greater than the first elastic allowance, at this time, the distance between the cup body 12 and the cutter disc assembly 14 is smaller, but the softness of the upper sealing member 1501 may be reduced, the sealing effect between the cup body 12 and the cutter disc assembly 14 cannot be better controlled, and moreover, the cup body 12 may shake more severely, and the noise generated between the cup body 12 and the cutter disc assembly 14 may also be larger.

It should be noted that, although the food processing machine disclosed in the present embodiment is a wall breaking machine, in practical applications, the technical solution disclosed in the present invention can also be applied to the food processing machine of the same kind, which is not described in detail in this application document.

In this embodiment, the upper seal 1501 is connected to the outer periphery of the lower seal 1502 such that the deck seal 15 has a U-shaped cross-section and the outer edge of the deck assembly 14 fits into the U-shaped opening. Because the upper seal 1501 and the lower seal 1502 form an integral U-shaped structure, separate installation is not required during assembly, which simplifies the assembly process of the seals. Moreover, because the cutter head assembly 14 is fixed on the step of the inner wall of the cutter holder, besides the buffer action of the upper sealing element 1501 and the lower sealing element 1502 on the cup body 12, the cup seat 13 and the cutter head assembly 14, the side edge of the U-shaped structure can also prevent the cutter head assembly 14 from colliding with the side wall of the cutter holder 13, so that the radial limit of the cutter head assembly 14 is realized, and the problem of water leakage can not occur due to the radial sliding and dislocation during the working of the food processor.

As shown in fig. 7, the cutterhead assembly 14 is provided with an annular projection 1401 on the inner side of the upper seal 1501, and the side wall of the annular projection 1401 abuts against the inner side of the upper seal 1501. The abutment of the annular protrusion 1401 sidewall with the upper seal 1501 may provide radial retention of the cutterhead assembly 14, ensuring stable operation of the food processor. The top surface of the annular protrusion 1401 is a plane, two side surfaces of the annular protrusion 1401 are respectively provided with an inclined surface inclined towards the center of the cup body 12 and a vertical surface abutted against the inner side of the upper sealing member 1501, and the inclined surfaces are used for guiding food material slurry to the center of the crushing cutter set when food material is processed and stirred.

Further, the top of annular projection 1401 is able to abut the bottom of cup 12 when upper seal 1501 is compressed by the operation of the food processor. When the food processor works, the upper sealing member 1501 is further compressed due to the vibration of the cutter head assembly 14, the annular protrusion 1401 enables the upper sealing member 1501 to enable the cutter head assembly 14 to be abutted against the lower end face of the cup body 12 before entering a limit compression state, the annular protrusion 1401 and the bottom face of the cup body 12 form limit, a gap between the annular protrusion 1401 and the bottom face of the cup body 12 is close to zero, the cup body 12 is enabled not to shake, a crack between the cutter head assembly 14 and the bottom face of the cup body 12 is not large or small, and the problem that fine food materials such as fishbone and the like are clamped in can be better.

The problem that small food materials such as fishbone are clamped in is avoided.

Example 2

As shown in fig. 8-12, the present embodiment is substantially identical to the technical features disclosed in embodiment 1, except that in the present embodiment, a plurality of annularly distributed protrusions 1301 are provided on the cup holder 13, and the lower seal 1502 is provided with a groove 1503 avoiding the protrusions 1301. Because of the protrusion 1301 and the groove 1503, the thickness of the lower seal 1502 at the protrusion 1301 is the lowest, and when the lower seal 1502 can no longer be compressed at the protruding position, a limit is formed between the lower seal 1502 and the cutter head assembly 14, so that the shaking of the cup body 12 during operation is reduced.

Further, the cup holder 13 is provided with a stepped surface provided toward the cutter head assembly 14 inside, and the projection 1301 is provided on the stepped surface.

In another embodiment, not shown, the projections are provided on the surface of the outer edge of the impeller assembly 14 facing the cup 13, since the impeller assembly 14 is typically of metal, modifications to the impeller forming process are contemplated if provided on the impeller assembly 14.

As shown in fig. 12, in this embodiment, the distance between the bottom surface of the groove 1503 and the upper end surface of the lower seal 1502 is H2, and H2 is 1mm, and in practical application, H2 can float in the range of 0.5mm to 1.5 mm. The elastic force of the cutter head sealing piece 15 at the lower part can be ensured, so that the vibration absorption and noise reduction effects are kept even if the cutter head assembly 14 is contacted with the bottom surface of the cup body 12. Even if unbalanced force is applied during the operation of the food processor, the food processor will not shake due to the limit position, and the gap H1 between the cutter head assembly 14 and the bottom surface of the cup body 12 of the mixing cup will not be large or small, so that the un-crushed fish bones will not be brought into the small gap H by the vortex when the food materials such as the fish bones are crushed. The embodiment can also ensure that the projection 1301 on the cup seat 13 does not directly and rigidly contact the bottom of the cutter head assembly 14, and the vibration reduction and noise reduction effects are achieved between the cutter head assembly 14 and the cup seat 13.

Additionally, if the projection 1301 is provided at the outer edge of the cutterhead assembly 14, the projection 1301 will directly abut the stepped surface of the cutterhead assembly 13, and likewise the thickness of the cutterhead seal 15 between the groove 1503 and the cutterhead assembly 14 is zero, so that the cup 13 is in rigid contact with the cutterhead assembly 14.

In addition, it may be provided that a partial region of the lower seal 1502 is in an extreme compression state in the axial direction of the cup 12 in a state where the cup 12 is in sealing pressure contact with the cutterhead assembly 14. The limit compression state has no elasticity, when a partial region of the lower cutter head sealing member 15 is in the limit compression state, relative rotation between the cutter head assembly 14 matched with the lower sealing member 1502 and the cutter seat 13 can be avoided, the limit compression state can avoid the cup body 12 from shaking due to the lower sealing member 1502, and meanwhile, the limit compression state can also ensure the sealing effect between the cutter head assembly 14 and the cutter seat 13.

The technical solution protected by the present invention is not limited to the above embodiments, and it should be noted that the technical solution of any one embodiment is combined with the technical solution of one or more other embodiments in the protection scope of the present invention.
