Since the cutting edge 411 of the first type blade 41 in the cutter 40 is circular arc-shaped, the curvatures of the cutting edge 411 of the first type blade 41 are consistent, so that the efficiency of crushing the food material by the first type blade 41 can be improved. Correspondingly, under the condition that the required crushing effect is not changed in unit time, the power of the cutter 40 can be properly reduced due to the higher crushing efficiency of the cutter 40, and the noise in the rotating process of the cutter 40 is further reduced; the reduction of the power of the cutter 40 can reduce the rotating speed of the cutter 40, so that the liquid level in the processing space 14 where the cutter 40 is positioned is lower, and the food in the cup body 11 is prevented from overflowing. Moreover, by arranging the accommodating chamber 63 for accommodating the first type blades 41 in a shape with a wide top and a narrow bottom, the accommodating chamber 63 and the first type blades 41 are matched in shape, so that the food materials are promoted to collide with the blades, and the crushing effect of the first type blades 41 is further improved.

The accommodating chamber 63 can be gradually narrowed from top to bottom, so that the accommodating chamber 63 and the first type blade 41 have better matching effect, and the food material crushing effect can be improved. In other embodiments, the size of the accommodating chamber 63 in the horizontal direction may not necessarily be all narrowed as the height decreases, for example, the accommodating chamber 63 may be allowed to be kept constant in the horizontal direction in some height intervals.

Furthermore, the narrowing range of the accommodating chamber 63 at each height from top to bottom can be changed continuously, so as to further improve the crushing effect of the first type of blades 41 on the food materials.

In one embodiment, the receiving chamber 63 may be a cavity surrounded by a lower end portion of an inner wall of the cup body 11 of the cooking cup 10 and a bottom wall of the cup body 11. That is, the receiving chamber 63 may be formed integrally with the cup body 11.

Further, the side wall 62 of the cutter head 60 is in a smooth curve shape from top to bottom, so that the narrowing range of the accommodating chamber 63 from top to bottom at each height is changed continuously, the operation of the food materials is facilitated, the collision probability of the food materials and the first type of blades 41 is improved, and the crushing efficiency is increased.

A heating member (e.g., heating wire) may be disposed below or inside the cutter head 60, so that the cutter head 60 serves as a mounting frame for the cutter 40 and also serves as a heating plate for heating the food material in the processing space 14.

The cutting edge 411 of the first type blade 41 may have a plurality of saw-tooth notches, which may be uniformly spaced, and the teeth of the saw-tooth notches are located on the same arc. Due to the arrangement of the saw-tooth-shaped gaps, the contact area between the food material and the blade edge 411 is further increased, and the contact probability between the food material and the blade edge 411 is improved. Wherein the cutting edge 411 of the first type blade 41 may extend obliquely downward.

The central angle of the cutting edges 411 of the first type of blades 41 may be greater than or equal to 90 degrees, preferably the central angle of the cutting edges 411 of the first type of blades 41 is greater than or equal to 120 degrees. With such an arrangement, the length of the cutting edge 411 of the first-type blade 41 is longer, which is beneficial to improving the contact probability of the food material and the cutting edge 411.

The number of the first type blades 41 may be two, two of the first type blades 41 may be oppositely disposed, and the cutting edge 411 of one of the first type blades 41 faces away from the cutting edge 411 of the other first type blade 41, that is, the distance between the cutting edge 411 of one of the first type blades 41 and the cutting edge 411 of the other first type blade 41 is larger than the distance between the cutting edge 411 of the other first type blade 41 and the back 412 of the other first type blade 41. So set up, the pivoted in-process of cutter 40, two the cutting edge 411 of first type blade 41 all faces the direction of rotation of cutter 40, and the efficiency of beating the edible material is higher, more does benefit to and smashes the edible material.

The back 412 of the first type of insert 41 may be recessed inward, and the back 412 may be rounded. Further, a circle b1 where the back 412 of one of the first type blades 41 is located may be inscribed in a circle a1 where the cutting edge 411 is located, and a circle b2 where the back 412 of the other one of the first type blades 41 is located may be inscribed in a circle a2 where the cutting edge 411 is located. Further, the circle b2 on which the back 412 of one first-type insert 41 is located is circumscribed with the circle a1 on which the cutting edge 411 of the other first-type insert 41 is located. So arranged, the lines of the first type of blade 41 can be made more aesthetically pleasing. The diameter of the circle a1 and the circle a2 may be 20mm to 80mm, preferably 45mm to 60mm, and the diameter of the circle b1 and the circle b2 may be 10mm to 40mm, preferably 20mm to 30 mm.

The first type of blade 41 may be provided with a pressure relief hole 413, and the pressure relief hole 413 may balance the pressure of the liquid on the upper and lower sides of the first type of blade 41, thereby facilitating the flow of the food material. The number of the pressure relief holes 413 can be one or more, and the total area of the pressure relief holes 413 of each first type blade 41 is greater than or equal to 60mm ²Preferably 80mm ²～100mm ². The shape of the pressure relief hole 413 may be substantially similar to the shape of the first type of blade 41, thereby making the first type of blade 41 more aesthetically pleasing overall.

Further, the pressure relief holes 413 on the two oppositely arranged first type blades 41 can be symmetrically arranged and have the same area, so that the oppositely arranged first type blades 41 are stressed in a balanced manner, and the operation of the cutter 40 is more stable.

The blades of the cutter 40 may further include a second type blade 42, the second type blade 42 includes a cutting edge 421 and a back 422 opposite to the cutting edge 421, and the cutting edge 421 of the second type blade 42 may be linear, that is, the cutting edge 421 is flush with each other. In the rotating process of the cutter 40, the second type blades 42 can cut larger pieces of food materials, the first type blades 41 can cut smaller pieces of food materials, and the two different types of blades are matched with each other, so that the food materials can be more favorably smashed.

The number of the second type blades 42 and the number of the first type blades 41 may be two, respectively, and two first type blades 41 are disposed oppositely and two second type blades 42 are disposed oppositely. The cutting edge 421 of the second-type blade 42 may deviate from the cutting edge 411 of the first-type blade 41, that is, the distance between the cutting edge 411 of the first-type blade 41 and the cutting edge 421 of the second-type blade 42 is greater than the distance between the cutting edge 411 of the first-type blade 41 and the back 422 of the second-type blade 42. So configured, the second type of blade 42 fits better with the first type of blade 41.

The cutter 40 may further include a mounting portion 43, and the first-type insert 41 and the second-type insert 42 are disposed on a circumferential side of the mounting portion 43. The second-type insert 42 and the first-type insert 41 may be integrally connected to the peripheral side of the mounting portion 43. In this way, the second type of insert 42 and the first type of insert 41 can be made of one metal sheet, so that the manufacturing process of the cutting tool can be simplified and the cost can be saved compared with the case that one metal sheet is used for each type of insert. In other embodiments, the first type of blade and the second type of blade may not be integrally formed.

The cutting edge 421 of the second type blade 42 may be disposed further upward in the housing chamber 63 than the cutting edge 411 of the first type blade 41. The first type of blade 41 and the mounting portion 43 may be disposed in the same plane, and the second type of blade 42 may extend obliquely upward with respect to the mounting portion 43. With such an arrangement, when the cutter 40 rotates, a low-pressure swirling area is formed in an area between the two second type blades 42, so as to generate a downward suction force on the food material, and the food material can be guided to the cutting edge 411 of the first type blade 41, thereby being beneficial to exerting the crushing effect of the first type blade 41.

The outermost ends of the second type blades 42 are further outward than the outermost ends of the first type blades 41. That is, the outermost end of the second type blades 42 is farther from the axis of rotation than the outermost end of the first type blades 41. The projection of the outermost end of the second type blade 42 in the horizontal direction is further outward than the projection of the outermost end of said first type blade 41 in the horizontal direction. The projection of the outermost end of the second type blade 42 in the horizontal direction can fall on the side wall 62 of the cutter disc 60, and the projection of the outermost end of the first type blade 41 in the horizontal direction can fall on the bottom wall 61 of the cutter disc 60 and also can fall on the side wall 62 of the cutter disc 60. So arranged, the second type blade 42 can be made to direct the food material to a greater extent at the cutting edge 411 of the underlying first type blade 41.

The angle a between the lower edge of the back 422 of the second-type insert 42 and the plane of the top surface of the mounting portion 43 may be in the range of 30 ° to 50 °, and preferably, may be in the range of 38 ° to 45 °. The distance between the top end of the second type blade 42 and the plane of the top surface of the mounting portion 43 may be 18mm to 24mm, preferably 21 mm. With such an arrangement, the suction force of the second type of blades 42 to the food material is larger in the rotating process of the cutter 40, which is more beneficial to improving the crushing effect of the cutter 40.

A straight line c can be formed by passing through the center of the circle B1 where the blade back 412 of the first blade 41 is located and the center of the circle B2, and an angle B between the bending line 423 of the second blade 42 and the straight line c ranges from 48 ° to 60 °. Preferably, the angle between the bending line 423 of the second blade 42 and the straight line c ranges from 50 ° to 55 °. By the arrangement, the suction force of the second type of blades 42 to the food materials in the rotating process of the cutter 40 is increased, so that the crushing effect of the cutter 40 can be improved.

The outermost point of the first type of blade 41 may form a first circumference during rotation and the outermost point of the mounting portion 43 may form a second circumference during rotation. The fluid in the cooking cup 10 cannot flow up and down in the range covered by the second circumference formed in the rotation process of the outermost part of the mounting part 43, and the food material cannot contact with the first-type blade 41, so that the crushing efficiency of the cutter 40 on the food material is not improved when the area of the second circumference is large. In order to improve the range of the up-and-down flow of the fluid in the cooking cup 10, the ratio of the area of the first circumference to the area of the second circumference can be 10-20. Preferably, the ratio of the area of the first circumference to the second circumference is in the range of 13.5-17.5, such as 14, 15, 16, 17. Due to the arrangement, the food material can flow up and down conveniently, so that the contact probability of the food material and the first blade 41 is high, and the crushing efficiency of the cutter 40 on the food material is improved. The end points of the two bending lines 423 located on the same side are connected to obtain a dividing line d1 and a dividing line d2 between the mounting portion 43 and the two first-type blades 41, and the region enclosed by d1, d2 and the two bending lines 423 is the mounting portion 43. The outermost of the first blade 41 refers to a position where the distance between the first blade 41 and the center of the mounting portion 43 is the largest, and the outermost of the mounting portion 43 refers to a position where the distance between the mounting portion 43 and the center thereof is the largest. The diameter of the second circumference formed during rotation at the outermost position of the mounting portion 43 is equal to the length of the longer diagonal line of the mounting portion 43. The diameter of the first circumference formed during rotation of the outermost one of the first type blades 41 is equal to the distance between the ends of the cutting edges 411 of the two first type blades 41.

The cutter 40 shown in fig. 6 includes two types of blades, i.e., a first type of blade 41 and a second type of blade 42, and the number of the first type of blade 41 and the number of the second type of blade 42 are two, respectively, but the present invention provides the cutter 40 without being limited thereto, and in other embodiments, the cutter 40 may include other types of blades, and the number of each type of blade may also exceed two.

In the manufacture of the cutter 40, the metal sheet as a raw material is first cut to form the metal sheet into a shape shown in fig. 10, and then the second type blade 42 is bent upward to obtain the cutter 40 shown in fig. 6. A gap 432 may be formed between the cutting edge 411 of the first type blade 41 and the second type blade 42, the gap 432 may be semicircular, and the diameter of the gap 423 may be greater than 1 mm. Because the cutting edge 411 of the first type blade 41 protrudes outwards, the second type blade 42 may contact with the first type blade 41 to deform during the upward bending process, and the notch 432 is more favorable for bending the second type blade 42 upwards, so as to prevent the second type blade 42 from deforming during the upward bending process. Because the back 412 of the first-type blade 41 is recessed inward, the distance between the back 412 and the second-type blade 42 is relatively large, and the second-type blade 42 can be prevented from contacting the back 412 in the process of bending upward.

The tool 40 may further include a lower blade 514, a lower mounting portion 511, a tool holder 53, a rotating shaft 52, a spacer 55, a spacer 56, and a clutch 57. The number of the lower blades 514 is at least two, and the lower blades 514 are provided on the circumferential side of the lower mounting portion 511. The lower blade 514 may be integrally formed with the lower mounting portion 511 or may be formed separately. The lower blade 514 may include a bent portion 512 extending downward from a side of the lower mounting portion 511 and a straight portion 513 extending from an end of the bent portion 512. The cutting edge of the lower blade 514 may extend obliquely downward.
