In order to ensure the overall strength of the existing mixing knife 100, most of the cutting angles are designed to be relatively large, but this will cause the mixing knife 100 to suffer from greater resistance when crushing food materials due to its large area of action, making the mixing knife 100 The higher the power, the faster the rotation speed drops, which in turn leads to poor pulverization effect of the mixing knife 100 , which affects the fineness of the pulverized ingredients and the working efficiency of the mixing knife 100 . In order to improve the pulverizing effect of the mixing knife 100, the existing mixing knife 100 generally designs the blade of the mixing knife 100 sharper to increase the cutting power of the mixing knife 100, but this will cause the blade to have a lower strength. When the mixing knife 100 cuts food with a large volume or high hardness, there is a certain probability that the blade will be bent and damaged, which will affect the crushing effect and service life of the mixing knife 100 . In view of the above problems, the present application proposes a mixing knife 100 .

Referring to Fig. 1 to Fig. 7, in the embodiment of the present application, the mixing knife 100 is applied to a cooking machine, including a mounting part 10 and at least one blade 30, the mounting part 10 is connected to a rotating shaft; the blade 30 is arranged on the mounting part 10 A mounting side 11 of the blade 30 includes an upper surface 31, a lower surface 33, and a side surface 35 connecting the upper surface 31 and the lower surface 33, the upper surface 31 includes a plane area 311 and a blade area 313, and the plane area 311 and the blade Surface area 313 is connected. The angle α formed by the blade surface area 313 and the lower surface 33 ranges from 5°≤α≤15°, and the side connecting the blade surface area 313 and the side surface 35 is recessed to form a plurality of blade teeth 3131 .

The technical solution of the present application sets the angle between the blade surface area 313 and the lower surface 33 of the blade 30 within a certain range, thereby reducing the chip angle of the blade 30 while ensuring the overall strength of the mixing knife 100, effectively improving the The pulverizing effect of the mixing knife 100. When the angle α ≥ 5° between the blade surface area 313 and the lower surface 33, as the angle increases, the thickness of the blade 30 will gradually increase, thereby effectively improving the structural strength of the blade 30 and improving the strength of the blade 30. to prevent the blade 30 from being bent and damaged due to excessive force when crushing food with high hardness; Under this range of angles, the angle at which the blade 30 cuts into the food material is relatively small, effectively reducing the contact area between the blade 30 and the food material, thereby reducing the force exerted by the crushed food material on the blade 30, making the resistance of the blade 30 less, reducing the The power loss of the mixing knife 100 is reduced, and the crushing efficiency of the mixing knife 100 is effectively improved.

And because the edge area 313 of the blade 30 is connected with the lower surface 33 by the side surface 35, the edge of the blade 30 has a certain thickness, the force on the edge of the blade is improved to a certain extent, and the crushing volume of the mixing knife 100 is relatively small. When using large or hard ingredients, the blade is less likely to be bent and damaged. Simultaneously, the blade area 313 and the side connected to the side surface 35 are recessed to form a plurality of blade teeth 3131, and the degree of stress of the blade teeth 3131 is smaller than that of the blade, but the sharpness of the blade teeth 3131 Larger than the blade. When the mixing knife 100 crushes food, the food will first contact the blade, and the food will be crushed into food blocks with smaller volume and hardness under the action of the blade; The volume and hardness are small and the force on the blade teeth 3131 is also small, so that the blade teeth 3131 are not easy to be bent and damaged, and the food block will be further crushed under the action of the blade teeth 3131, so that the food materials can be crushed more. exquisite. By forming a plurality of blade teeth 3131 at the edge of the blade 30, the crushing effect of first crushing and then grinding can be achieved, so that the crushing effect of the mixing knife 100 is better, and the degree of fineness of the crushed food material is better; and in the crushing process, The thicker blade effectively increases the strength of the blade 30, and at the same time effectively protects the sharper blade teeth 3131, so that the blade teeth 3131 can crush food materials better, and effectively improves the reliability and practicability of the mixing knife 100 .

Further, referring to Fig. 5 and Fig. 6, in one embodiment of the present application, the edge area 313 includes a first edge surface 3133 and a second edge surface 3135, the first edge surface 3133 is connected to the plane area 311, and the first edge surface The included angle between the surface 3133 and the lower surface 33 is α; the second blade surface 3135 connects the first blade surface 3133 and the side surface 35, and the range value of the included angle β between the second blade surface 3135 and the lower surface 33 is: 30°≤β≤60°.

Wherein, it can be understood that, in the crushing process, the second blade surface 3135 will be in contact with the food earlier, and by locally increasing the angle between the second blade surface 3135 and the lower surface 33, the stability of the blade 30 can be further locally improved. The structural strength is beneficial to better protect the blade 30 from being bent and damaged due to excessive force during the crushing process. When the included angle β between the second edge surface 3135 and the lower surface 33 is ≥30°, as the angle increases, the thickness at the edge of the blade 30 will locally increase, thereby further increasing the structural strength of the blade 30, so that The mixing knife 100 is more reliable; when the included angle β≤60° between the second blade surface 3135 and the lower surface 33 is within this range, the blade of the blade 30 receives less force from the food material, and the blade of the blade 30 The resistance suffered is also small, so the power loss of the blade 30 is small, effectively ensuring the crushing efficiency of the blade 30 .

Further, referring to FIG. 1 and FIG. 2 , in one embodiment of the present application, the blade tooth 3131 connects the blade face area 313 and the side surface 35 . Alternatively, the blade teeth 3131 are connected to the blade area 313 and penetrate through the side surface 35 .

In this embodiment, the blade tooth 3131 can connect the blade surface area 313 and the side surface 35, which is beneficial to increase the thickness of the blade 30 at the blade tooth 3131, improve the structural strength of the blade tooth 3131, and effectively prevent the blade tooth 3131 from being damaged. There is a certain probability of damage due to excessive force, so that the blade teeth 3131 can crush food materials better, and the overall structural strength of the mixing knife 100 is improved. In another embodiment, the blade teeth 3131 can be connected to the blade surface area 313 and penetrate through the side surface 35. With this structural design, the sharpness of the blade teeth 3131 can be effectively increased, so that the mixing knife 100 has a better crushing effect and can effectively simplify the processing procedure of the blade 30, reduce the workload of the staff, and help improve the production efficiency of the mixing knife 100.

Further, referring to FIG. 2 to FIG. 6 , in one embodiment of the present application, the range value of the width W1 of the edge area 313 is: W1≥6mm. And/or, the range value of the length L of the blade tooth 3131 is: 2mm≤L≤5mm. And/or, the part of the side surface 35 connecting the edge area 313 and the lower surface 33 is defined as the cutting edge 353 , and the range of the width W2 of the cutting edge 353 is: 0.1mm≤W2≤0.5mm.

It can be understood that when the overall width of the blade 30 is constant, making the width W1 of the blade surface area 313 ≥ 6mm can further reduce the angle at which the blade 30 cuts into the food, effectively reducing the resistance of the blade 30 to the food, and the loss of the blade 30. The power can be further reduced, which improves the crushing efficiency of the mixing knife 100 better.

When the mixing knife 100 is running at high speed, if the length L of the blade teeth 3131 is greater than or equal to 2 mm, the contact area between the food block and the blade teeth 3131 can be effectively increased, so that the food materials can be crushed more fully, which is conducive to further increasing the fineness of the food materials being crushed. To a certain extent, the practicability of the mixing knife 100 is improved. At the same time, if the length L of the blade teeth 3131 is less than or equal to 5 mm, the mechanical strength of the blade 30 can be effectively improved. Since the thickness of the blade 30 at the blade teeth 3131 is small, the blade teeth 3131 with too long length may be damaged due to excessive force when crushing hard foodstuffs, so the length of the blade teeth 3131 should be within this value range It can effectively enhance the structural strength of the blade 30 at the blade teeth 3131, and can prevent larger food pieces from acting on the blade teeth 3131, effectively protecting the overall structure of the blade 30, and improving the structural stability and stability of the mixing knife 100. reliability.

Secondly, when the mixing knife 100 is in operation, the cutting edge 353 with a certain width will contact the food material first, and then break the food material into a certain volume of food material blocks, and then contact the blade teeth 3131 for further crushing. If the width W2 of the cutting edge 353≥0.1mm, the thickness of the blade 30 at the cutting edge 353 can be effectively improved, and the structural strength of the blade 30 at the cutting edge 353 can be improved, effectively preventing the mixing knife 100 from being overstressed during high-speed operation. It is large and has a certain probability of being damaged, which further improves the structural stability of the mixing knife 100 . Simultaneously, if the width W2≤0.5mm of the cutting edge 353, it can guarantee that the thickness of the blade 30 at the cutting edge 353 will not be too large, so that the blade 30 has a certain sharpness at the cutting edge 353, so that the mixing knife 100 can reach The better crushing effect further improves the crushing efficiency of the mixing knife 100 .

Referring to Fig. 1, Fig. 3 and Fig. 5, in one embodiment of the present application, the part that defines the side surface 35 connecting the planar area 311 and the lower surface 33 is the back of the knife 351, the back of the knife 351 is designed in an arc shape, and the back of the knife 351 is provided with protrusions Structure 3511.

When the cooking machine is in operation, the high-speed motor will drive the mixing knife 100 to rotate at a high speed in the cooking machine. Because the thickness of the knife back 351 is relatively large, a negative pressure zone will be formed at the knife back 351 at this time, resulting in that the ingredients cannot be well placed on the knife back 351. If there is no flow, the food cannot be fully agitated, which in turn will cause insufficient crushing of the ingredients. At the same time, under the action of negative pressure, the resistance that the blade 30 receives when it rotates will also increase. Therefore, in this embodiment, by setting the back of the knife 351 in an arc shape and providing the raised structure 3511, the negative pressure at the back of the knife 351 can be broken, and the liquid flow of the cooking machine is disturbed, so that the stirring range of the ingredients is greater and the pulverization is more uniform. At the same time, the influence of negative pressure is eliminated, so that the mixing blade 100 can rotate more stably, the resistance on the blade 30 is reduced, and the vibration of the blade 30 is reduced, thereby further improving the crushing efficiency of the mixing blade 100 .

Referring to FIG. 1 , FIG. 3 and FIG. 5 , in one embodiment of the present application, the blade 30 includes four blades 30 , and the four blades 30 are arranged symmetrically with the installation part 10 as the center of symmetry.

It can be understood that the design of four blades 30 can make the food materials be fully chipped and crushed. At the same time, compared with the design with more blades 30, the use of four blades 30 can effectively reduce the cooking time when the mixing knife 100 is running at high speed. The load of the motor makes the power loss of the blade 30 lower, effectively improving the crushing efficiency of the mixing knife 100.

And by setting the four blades 30 symmetrically with the installation part 10 as the center of symmetry, the overall force of the mixing knife 100 can be more uniform, effectively improving the dynamic balance of the mixing knife 100, so that the mixing knife 100 will not produce any damage when running at high speed. Excessive vibration and noise effectively reduce the resistance of the blade 30 due to vibration, ensure that the mixing blade 100 has a good crushing efficiency, and at the same time play an active noise reduction effect.

Further, referring to Fig. 1, Fig. 3 and Fig. 5, in one embodiment of the present application, the blade 30 is bent, and the range value of the angle γ between the blade 30 and the mounting part 10 is: 10°≤γ≤40° . And/or, the four blades 30 are integrated with the installation part 10 .

In this embodiment, in order to make the overall strength of the mixing knife 100 better and improve the integrity of the mixing knife 100, the four blades 30 and the mounting part 10 can be arranged in an integrated structure, and the integrated structure can make the mixing knife 100 The structure is neater. Compared with the connected and formed mixing knife 100, the one-piece structure of the mixing knife 100 has no installation gap and has better strength. It can effectively avoid the possibility of breaking the installation part due to excessive force during high-speed operation. , ensuring the structural reliability of the mixing knife 100. At the same time, during the production process, the integrated mixing knife 100 can effectively simplify the production process and production difficulty, reduce the workload of the staff, and improve production efficiency.

Secondly, when the mixing knife 100 is running at a high speed, the ingredients will reciprocate along the central axis of the cooking machine under the action of the blade 30. At this time, bending the blade 30 can further increase the contact area between the blade 30 and the ingredients. So that the ingredients can be crushed more fully. Wherein, if the angle between the blade 30 and the installation part 10 is γ≥10°, the force of the blade 30 acting on the food along the central axis of the cooking machine can be effectively reduced, effectively preventing the food from being ejected from the blade 30 due to excessive force. The distance is longer, so that the ingredients can be better concentrated near the mixing knife 100 to be pulverized. If the angle between the blade 30 and the installation part 10 is γ≤40°, within this angle range, the bending angle of the blade 30 will not be too large, so as to prevent the blade 30 from forming a certain cavity during the rotation process and causing some food materials to have a certain degree of deformation. The probability is not sufficiently crushed, which effectively improves the degree of fineness of the crushed ingredients, and further improves the stirring efficiency of the mixing knife 100 .

Referring to FIG. 3 and FIG. 5 , in one embodiment of the present application, the width of the blade 30 is gradually reduced in a direction away from the mounting part 10 .

In this embodiment, the blade 30 forms a triangular-like structure by making the width of the blade 30 gradually decrease in the direction away from the mounting portion 10 , thereby further improving the structural strength of the blade 30 . And the width value of the tip of the blade 30 away from the installation part 10 is the smallest, which is conducive to improving the sharpness of the tip of the blade, so that the blade 30 can better stir and pulverize the food materials accumulated on the inner wall of the cooking machine, and further improve the mixing knife 100. smashing effect.

Further, referring to FIG. 3 and FIG. 5 , in one embodiment of the present application, the cutting edge of the blade 30 away from the mounting side 11 is arc-shaped.

It can be understood that by setting the cutting edge of the blade 30 far away from the mounting side 11 into an arc shape, the arc-shaped guiding effect can make the food material pass through the cutting edge of the blade 30 away from the mounting part 10 better. Sliding over prevents the tip of the blade from being broken and damaged due to a large force, which is beneficial to further reducing the resistance on the blade 30 and improving the crushing efficiency of the mixing knife 100 .

The present application also proposes a cooking machine (not shown), the cooking machine includes a body assembly (not shown) and a stirring knife 100, the stirring knife 100 is installed on the body assembly, the specific structure of the stirring knife 100 refers to the above-mentioned embodiment, Since this cooking machine adopts all the technical solutions of all the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, and will not repeat them one by one here.
