Description

Technical Field

[0001] The utility model relates to the technical field of household electrical appliances, in particular to a food processor with good crushing effect. Background Art

[0002] Existing food processors such as meat grinders and baby food processors usually include a mixing cup with a mixing blade and a main unit that cooperates with the mixing cup. When using the food processor, the user places the food in the mixing cup, and the mixing blade is driven by the motor in the main unit to process the food. However, the traditional mixing blade has only two single-layer blades, and the crushing effect and efficiency are poor. In order to solve this problem, the utility model patent CN220124556U previously applied by the applicant discloses a crushing component and a food processor, in which the blades are arranged as multiple blades and are spaced apart along the axial direction of the blade shaft to achieve cutting of food in a larger range, thereby improving the crushing effect and efficiency of the food. In order to increase the cutting rate and the vertical cutting range, the applicant arranges the blade at the bottom of the blade shaft as a first extension and a second extension bent upward relative to the first extension, and a third extension bent downward is provided between the first extension and the blade shaft to increase the vertical cutting space and improve the cutting effect. However, in actual use of the above-mentioned machine, a single bent blade still cannot cut more food at the bottom, especially when preparing complementary foods. Due to the high fluidity of the food, most of the food settles at the bottom of the cup body, resulting in a not very ideal food cutting effect. Although the food cutting effect of our company's prior solution is significantly improved, it still needs further improvement and optimization. Utility Model Content

[0003] The purpose of the utility model is to provide a food processor with good crushing effect, which is used to make further optimization and improvement on the basis of the patent previously applied for by the applicant to improve the crushing effect of food.

[0004] To achieve the above-mentioned purpose, the utility model provides a food processor with good crushing effect, including a mixing cup with a mixing knife therein and a main unit matched with the mixing cup, the mixing knife is arranged along the axial direction of the mixing cup, the mixing knife includes a knife shaft, and the bottom end of the knife shaft is positioned and matched with the bottom of the mixing cup, and the top end of the knife shaft is positioned and matched with the cup cover or the main unit of the mixing cup, the mixing knife is provided with a multi-layer knife group along the axial direction of the knife shaft, the knife group located at the bottom of the mixing knife includes a first knife blade and a second knife blade which are arranged laterally opposite to each other, the first knife blade is provided with a first bending portion extending outward and obliquely downward, a connecting portion connected to the end of the first bending portion, and a second bending portion connected to the end of the connecting portion and extending outward and obliquely upward, and the inclination angle of the connecting portion is smaller than the inclination angles of the first bending portion and the second bending portion, the end of the second knife blade is provided with a third bending portion extending outward and obliquely upward, and the top end of the second bending portion is not higher than the top end of the third bending portion.

[0005] The present application arranges the mixing blade to have a multi-layer blade group along the axial direction of the blade shaft, so that when the user uses the food processor to process food, food at different axial depths in the mixing cup can be cut by different blade groups, which helps to improve the delicacy and efficiency of food processing. At the same time, the first blade is provided with a first bending portion extending outward and obliquely downward, a connecting portion connected to the end of the first bending portion, and a second bending portion connected to the end of the connecting portion and extending outward and obliquely upward. On the one hand, in the first blade processing and forming stage, the lower mold is concave to form a groove adapted to the first blade, and the upper mold can be pressed down from top to bottom to realize the stamping processing of the first blade, and the forming method is simple and the processing efficiency is high; on the other hand, when processing food, the food passing through the first blade will be subjected to the inward force of the first bending portion and the second bending portion, wherein the food is subjected to the outward force of the first bending portion obliquely and the inward force of the second bending portion obliquely, so that the food will collide and mix at the connecting portion during the mixing process, and fall back to the connecting portion during the falling process to realize effective cutting, thereby effectively avoiding the situation that the food located on the periphery of the first blade is thrown onto the wall of the mixing cup, causing the food to adhere to the wall of the cup and unable to realize further cutting, and at the same time avoiding the situation that the food located on the inner side of the first blade is adhered or hooked on the blade shaft, causing the part of the food to be difficult to fully participate in the crushing, further improving the processing and crushing effect of the food.

[0006] Moreover, the inclination angle of the connecting portion is smaller than the inclination angles of the first bending portion and the second bending portion, which effectively avoids the situation that the food is subjected to the lateral force of the connecting portion when passing through the connecting portion due to the large inclination angle of the connecting portion, causing the food to move inward or outward for a large distance, resulting in the inability to further effectively cut the food or adhere to the inner wall of the mixing cup, further improving the food processing effect. At the same time, the top of the second bending portion is not higher than the top of the third bending portion, so that the third bending portion can stir the food at the bottom of the cup upward as high as possible when rotating, and the stirred food can fall more into the cutting range of the connecting portion under the circumferential thrust, so that the food can be more fully cut and crushed, and at the same time, the blade tips of the first blade and the second blade can realize cutting of food at different heights, thereby further improving the axial cutting coverage area of ​​the entire mixing blade, and can further cut more food, and after the blade tips of the two blades are set to be bent upward, on the basis of expanding their axial cutting range, the first blade and the second blade can be set closer to the bottom wall of the mixing cup, thereby effectively preventing the food from adhering to the bottom wall of the mixing cup, further improving the crushing effect of the food.

[0007] In a preferred implementation of a food processor with good crushing effect, the second blade also includes a blade main body connected between the blade shaft and the third bending portion, the distance between the top of the third bending portion and the top of the blade main body is L1, and the distance between the top of the blade main body and the bottom of the upper adjacent blade group is L2, wherein: 0.25L2≤L1≤0.5L2.

[0008] By setting L1 and L2 to 0.25L2≤L1≤0.5L2, it is possible to avoid the situation where the third bend portion extends upwardly for a shorter distance than the distance between the blade body and the adjacent blade group, resulting in the third bend portion being unable to cut more food when the food passes between the second blade and the upper blade group, causing too much food to pass over the third bend portion, resulting in poor food cutting effect and low efficiency; at the same time, it is possible to avoid the situation where the third bend portion extends upwardly for a longer distance than the distance between the blade body and the adjacent blade group, resulting in the food being stuck between the third bend portion and the adjacent blade group when passing between the second blade and the upper blade group, thereby causing this part of the food to be unable to be further cut, affecting the fineness and taste of the food.

[0009] In a preferred implementation of a food processor with good crushing effect, the inclination angle of the second bending portion is smaller than the inclination angle of the third bending portion; or,

[0010] The height of the second bending portion bending upward is smaller than the height of the third bending portion bending upward.

[0011] By setting the inclination angle of the second bending portion to be smaller than the inclination angle of the third bending portion, the third bending portion can have a better tumbling effect, so that the food at the bottom of the cup body can be better stirred upward, and the stirred food can fall more into the cutting range of the connecting portion under the circumferential thrust, thereby further improving the cutting effect. At the same time, the second bending portion and the third bending portion can cut food within different circumferential ranges, which can further expand the cutting range of the first blade and the second blade.

[0012] In a preferred implementation of a food processor with good crushing effect, the angle A1 between the first bent portion and the horizontal plane satisfies: 5°≤A1≤60°; and / or,

[0013] An angle A2 between the second bent portion and the horizontal plane satisfies: 0°<A2≤60°.

[0014] By setting the included angle A1 between the first bending portion and the horizontal plane to satisfy: 5°≤A1≤60°, it is avoided that the bending angle of the first bending portion is too small, resulting in the food passing through the first bending portion not being subjected to an effective outward force, and further resulting in the food being unable to be driven to the connecting portion, resulting in poor food crushing effect; at the same time, it is avoided that the bending angle of the first bending portion is too large, resulting in the food passing through the first bending portion being subjected to a large outward force, resulting in the food directly splashing onto the inner wall of the blender cup, causing food waste.

[0015] In a preferred implementation of the food processor with good crushing effect, the connecting portion extends in a horizontal direction.

[0016] By setting the connection part to extend in the horizontal direction, the angle between the first bending part and the connection part and the angle between the second bending part and the connection part are both obtuse angles, so that a cleaning dead angle with a small angle will not be formed, and the food will not remain in the aforementioned angle, ensuring that the food is fully cut and crushed. At the same time, the food is relatively stable when it falls on the connection part, effectively avoiding the situation where the food falling on the connection part moves toward the lower side and causes the material to accumulate at a low place. It also further avoids the situation where the food is subjected to the lateral force of the connection part when passing through the connection part due to the large inclination angle of the connection part, causing the food to move a large distance inward or outward, resulting in the inability to achieve further effective cutting of the food or adhere to the inner wall of the mixing cup, further improving the food processing effect.

[0017] In a preferred implementation of a food processor with good crushing effect, the knife group includes a first knife group provided with a first knife blade and a second knife blade, a second knife group arranged above the first knife group, and a third knife group arranged above the second knife group, and the distance between the first knife group and the second knife group is smaller than the distance between the second knife group and the third knife group.

[0018] By setting the knife group to three knife groups, the ingredients are cut by knife groups in three dimensions in the axial direction of the mixing cup, ensuring effective cutting of the ingredients and further improving the crushing effect of the ingredients. At the same time, the distance between the first knife group and the second knife group is smaller than the distance between the second knife group and the third knife group, so that a large amount of ingredients at the bottom of the mixing cup can be mixed and cut with the participation of the first knife group and the second knife group, which helps to further improve the crushing effect.

[0019] In a preferred implementation of a food processor with good crushing effect, the distance L2 between the first knife group and the second knife group and the distance L3 between the second knife group and the third knife group satisfy: 1 / 3≤L2 / L3≤2 / 3.

[0020] By making the distance L2 between the first knife group and the second knife group and the distance L3 between the second knife group and the third knife group satisfy the following: 1 / 3≤L2 / L3≤2 / 3, it is avoided that the distance between the first knife group and the second knife group is smaller than the distance between the second knife group and the third knife group, resulting in the food being stuck between the third bending portion and the adjacent knife group when passing between the first knife group and the second knife group, thereby causing the part of the food to be unable to be further cut and affecting the fineness and taste of the food; at the same time, it is avoided that the distance between the first knife group and the second knife group is larger than the distance between the second knife group and the third knife group, resulting in the first knife group and the second knife group being unable to cut more food, resulting in too much food passing over the first knife group, resulting in poor food cutting effect and low efficiency.

[0021] In a preferred implementation of a food processor with good crushing effect, the first blade extends in an arc shape in the opposite direction of the rotation direction of the stirring blade, so that the first bending portion is located upstream of the rotation direction of the second bending portion.

[0022] By setting the first blade along the stirring blade to extend in an arc shape in the opposite direction of the rotation direction, so that the first bending portion is located upstream of the rotation direction of the second bending portion, when the first blade rotates, the food passes through the first blade, and moves downward and backward under the action of the first bending portion, and when the food passes through the second blade, it moves forward under the action of the second bending portion, so that the food is moved to the connecting portion and effectively cut on the cutting surface of the longer connecting portion, thereby further improving the crushing effect.

[0023] In a preferred implementation of a food processor with good crushing effect, the blade shaft includes a plastic sleeve, a connector disposed above the plastic sleeve, and a shaft sleeve disposed below the plastic sleeve, and the plastic sleeve, the connector and the shaft sleeve are integrally formed by injection molding; or,

[0024] The knife shaft comprises a steel sleeve which is hollow inside and has an opening at the bottom, a shaft sleeve fixed at the opening, and a connecting head fixed above the steel sleeve, and the connecting head is made of plastic material.

[0025] By configuring the cutter shaft to include a plastic sleeve, a connector disposed above the plastic sleeve, and a shaft sleeve disposed below the plastic sleeve, and the plastic sleeve, the connector, and the shaft sleeve are integrally formed by injection molding, the step of connecting and matching the three is omitted, which helps to improve assembly efficiency. At the same time, it helps to improve the coaxiality of the three, ensure the stability of the cutter shaft when rotating, and further improve the crushing effect.

[0026] By setting the blade shaft to include a steel sleeve with a hollow interior and an opening at the bottom, a shaft sleeve fixed at the opening, and a connector fixed above the steel sleeve, and the connector is made of plastic, the overall strength of the blade shaft is greatly improved, effectively avoiding deformation during the stirring process, and the blade shaft can be placed in a heated environment to prevent color change. In addition, the connector made of plastic can reduce the transfer of heat to the connector, thereby effectively avoiding the user's hands from getting hot when holding the connector, and improving the user experience.

[0027] In a preferred implementation of a food processor with good crushing effect, when the knife shaft includes a steel sleeve, the knife shaft also includes a connecting piece, the connecting piece passes through the steel sleeve and is fastened to a connecting head, and a sealing piece is clamped between the connecting head and the top wall of the steel sleeve.

[0028] By clamping a seal between the connector and the top wall of the steel sleeve, on the one hand, the stability of the connection between the connector and the steel sleeve can be improved and the matching strength between the two can be ensured; on the other hand, the deformation ability of the seal can effectively avoid the situation where the connector and the steel sleeve are not properly connected due to assembly and production errors.

[0040] It should be noted that many specific details are elaborated in the following description to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific implementation methods disclosed below.

[0041] like Figures 1 to 7 As shown, the utility model provides a food processor with good crushing effect, including a mixing cup 3 with a mixing knife 2 therein and a main unit 1 matched with the mixing cup 3, the mixing knife 2 is arranged along the axial direction of the mixing cup 3, the mixing knife 2 includes a knife shaft 21, and the bottom end of the knife shaft 21 is positioned and matched with the bottom of the mixing cup 3, and the top end of the knife shaft 21 is positioned and matched with the cup cover of the mixing cup 3 or the main unit 1. Specifically, as shown in FIG. Figure 1 As shown, it can be a food supplement machine, including a machine base with a receiving chamber, a mixing cup 3 is arranged in the receiving chamber, a main machine 1 is covered on the receiving chamber, and the top end of the knife shaft 21 is positioned and matched with the main machine 1 and is connected to the output shaft in the main machine 1. Of course, it can also be a meat grinder. When the main machine 1 is arranged below the mixing cup 3, the mixing cup 3 includes a cup body and a cup cover, the bottom end of the knife shaft 21 is connected to the motor 11 in the main machine 1, and the top end is positioned and matched with the cup cover; when the main machine is arranged above the mixing cup 3, the top end of the knife shaft 21 is positioned and matched with the main machine 1 and is connected to the output shaft in the main machine 1.

[0042] The mixing blade 2 is provided with a multi-layer blade group along the axial direction of the blade shaft 21. The blade group located at the bottom of the mixing blade 2 includes a first blade 241 and a second blade 242 which are arranged laterally opposite to each other. It should be noted that the laterally opposite arrangement of the first blade 241 and the second blade 242 in the present application specifically refers to that the first blade 241 and the second blade 242 are located in the same horizontal plane and on the laterally opposite sides of the blade shaft 21. The first blade 241 is provided with a first bending portion 2411 extending outward and obliquely downward, a connecting portion 2412 connected to the end of the first bending portion 2411, and a second bending portion 2413 connected to the end of the connecting portion 2412 and extending outward and obliquely upward, and the inclination angle of the connecting portion 2412 is smaller than the inclination angles of the first bending portion 2411 and the second bending portion 2413. The end of the second blade 242 is provided with a third bending portion 2421 extending outward and obliquely upward, and the top of the second bending portion 2413 is not higher than the top of the third bending portion 2421.

[0043] The present application sets the mixing blade 2 to have a multi-layer blade group along the axial direction of the blade shaft 21, so that when the user uses the food processor to process food, the food at different axial depths in the mixing cup 3 can be cut by different blade groups, which helps to improve the delicacy and efficiency of food processing. At the same time, the first blade 241 is provided with a first bending portion 2411 extending outward and obliquely downward, a connecting portion 2412 connected to the end of the first bending portion 2411, and a second bending portion 2413 connected to the end of the connecting portion 2412 and extending outward and obliquely upward. On the one hand, during the processing and forming stage of the first blade 241, the lower mold is concave to form a groove adapted to the first blade 241, and the upper mold is pressed from top to bottom to achieve the stamping process of the first blade 241. The forming method is simple and the processing efficiency is high. On the other hand, when processing food, the food passing through the first blade 241 will be affected by the first bending portion 2411 and the second bending portion 2413. The food is subjected to the outward force of the first bending portion 2411 and the inward force of the second bending portion 2413, so that the food will collide and mix at the connecting portion 2412 during the stirring process, and fall back to the connecting portion 2412 during the falling process to achieve effective cutting, thereby effectively avoiding the situation where the food located at the periphery of the first blade 241 is thrown onto the wall of the stirring cup 3, causing the food to adhere to the wall of the cup and unable to be further cut, and at the same time avoiding the situation where the food located on the inner side of the first blade 241 is adhered or hooked on the blade shaft 21, causing the situation where this part of the food is difficult to fully participate in the crushing, thereby further improving the processing and crushing effect of the food.

[0044] In addition, the inclination angle of the connecting portion 2412 is smaller than the inclination angles of the first bending portion 2411 and the second bending portion 2413, which effectively avoids the situation where the connecting portion 2412 has a large inclination angle, causing the food to be subjected to the lateral force of the connecting portion 2412 when passing through the connecting portion 2412, causing the food to move a large distance inward or outward, resulting in the inability to further effectively cut the food or adhering to the inner wall of the mixing cup 3, thereby further improving the food processing effect. At the same time, the top of the second bending portion 2413 is not higher than the top of the third bending portion 2421, so that the third bending portion 2421 can stir the food at the bottom of the cup as high as possible upward when rotating, and the stirred food can fall more into the cutting range of the connecting portion 2412 under the circumferential thrust, so that the food can be more fully cut and crushed, and at the same time, the blade tips of the first blade 241 and the second blade 242 can achieve cutting of food at different heights, thereby further improving the axial cutting coverage area of ​​the entire mixing knife 2, and can further cut more food. After the blade tips of the two blades are set to bend upward, on the basis of expanding their axial cutting range, the first blade 241 and the second blade 242 can be set closer to the bottom wall of the mixing cup 3, thereby effectively preventing the food from adhering to the bottom wall of the mixing cup 3, and further improving the crushing effect of the food.

[0045] As a preferred implementation of the present application, Figure 3 As shown, the second blade 242 also includes a blade body 2422 connected between the blade shaft 21 and the third bending portion 2421, the distance between the top of the third bending portion 2421 and the top of the blade body 2422 is L1, and the distance between the top of the blade body and the bottom of the adjacent blade group above is L2, wherein: 0.25L2≤L1≤0.5L2.

[0046] By setting L1 and L2 to 0.25L2≤L1≤0.5L2, it is possible to avoid the situation where the third bending portion 2421 extends upwardly for a shorter distance than the distance between the blade body and the adjacent blade group, resulting in the third bending portion 2421 being unable to cut more food when the food passes between the second blade 242 and the upper blade group, causing too much food to pass over the third bending portion 2421, resulting in a poor food cutting effect and low efficiency; at the same time, it is possible to avoid the situation where the third bending portion 2421 extends upwardly for a longer distance than the distance between the blade body and the adjacent blade group, resulting in the food being stuck between the third bending portion 2421 and the adjacent blade group when passing between the second blade 242 and the upper blade group, thereby causing this part of the food to be unable to be further cut, affecting the fineness and taste of the food.

[0047] It should be noted that the present application does not specifically limit the relative relationship between the second bending portion 2413 and the third bending portion 2421. As a preferred embodiment of the present application, Figure 4As shown, the inclination angle of the second bending portion 2413 is smaller than the inclination angle of the third bending portion 2421 .

[0048] By setting the inclination angle of the second bending portion 2413 to be smaller than the inclination angle of the third bending portion 2421, the second bending portion 2413 and the third bending portion 2421 can cut food within different circumferential ranges, which can further expand the cutting range of the first blade 241 and the second blade 242.

[0049] As another preferred embodiment of the present application, Figure 4 As shown, the upward bending height of the second bending portion 2413 is smaller than the upward bending height of the third bending portion 2421 .

[0050] It should be noted that the present application does not specifically limit the bending angles of the first bending portion 2411 and the second bending portion 2413. As a preferred embodiment of the present application, Figure 4 As shown, the angle A1 between the first bending portion 2411 and the horizontal plane satisfies: 5°≤A1≤60°. More preferably, the angle A1 between the first bending portion 2411 and the horizontal plane is 14°, 30°, 50°, etc.

[0051] By setting the angle A1 between the first bending portion 2411 and the horizontal plane to satisfy: 5°≤A1≤60°, it is avoided that the bending angle of the first bending portion 2411 is too small, resulting in the food passing through the first bending portion 2411 not being subjected to an effective outward force, and then resulting in the food being unable to be driven to the connecting portion 2412, resulting in a poor food crushing effect; at the same time, it is avoided that the bending angle of the first bending portion 2411 is too large, resulting in the food passing through the first bending portion 2411 being subjected to a large outward force, resulting in the food directly splashing onto the inner wall of the mixing cup 3, causing food waste.

[0052] As a preferred implementation of the present application, Figure 4 As shown, the included angle A2 between the second bending portion 2413 and the horizontal plane satisfies: 0°<A2≤60°. More preferably, A2 satisfies A2=31°, 40°, 50°, etc.

[0053] It should be noted that the present application does not specifically limit the extension direction of the connecting portion 2412, which may extend obliquely downward or obliquely upward. As a preferred embodiment of the present application, Figure 4 As shown, the connecting portion 2412 extends in the horizontal direction.

[0054] By setting the connection part 2412 to extend in the horizontal direction, the angle between the first bending part 2411 and the connection part 2412 and the angle between the second bending part 2413 and the connection part 2412 are both obtuse angles, so that a cleaning dead angle with a small angle will not be formed, and the food will not remain in the aforementioned angle, ensuring that the food is fully cut and crushed. At the same time, the food is relatively stable when it falls on the connection part 2412, effectively avoiding the situation where the food falling on the connection part 2412 moves toward the lower side and causes the material to accumulate at the lower place. It further avoids the situation where the connection part 2412 has a large inclination angle, causing the food to be subjected to the lateral force of the connection part 2412 when passing through the connection part 2412, causing the food to move inward or outward for a large distance, resulting in the inability to achieve further effective cutting of the food or adhering to the inner wall of the mixing cup 3, further improving the food processing effect.

[0055] As a preferred embodiment of the present application, Figure 2 As shown, the knife group includes a first knife group 24 having a first knife blade 241 and a second knife blade 242, a second knife group 23 arranged above the first knife group 24, and a third knife group 22 arranged above the second knife group 23, and the distance between the first knife group 24 and the second knife group 23 is smaller than the distance between the second knife group 23 and the third knife group 22.

[0056] By providing three knife groups, the food is cut by three-dimensional knife groups in the axial direction of the mixing cup 3, ensuring effective cutting of the food, and further improving the crushing effect of the food. At the same time, the distance between the first knife group 24 and the second knife group 23 is smaller than the distance between the second knife group 23 and the third knife group 22, so that a large amount of food at the bottom of the mixing cup 3 can be mixed and cut with the participation of the first knife group 24 and the second knife group 23, which helps to further improve the crushing effect.

[0057] It should be noted that the present application does not specifically limit the specific relationship between the distance between the first knife group 24 and the second knife group 23 and the distance between the second knife group 23 and the third knife group 22. As a preferred embodiment of the present application, Figure 3 As shown, the distance L2 between the first knife group 24 and the second knife group 23 and the distance L3 between the second knife group 23 and the third knife group 22 satisfy: 1 / 3≤L2 / L3≤2 / 3.

[0058] By satisfying the following conditions: 1 / 3≤L2 / L3≤2 / 3, the distance L2 between the first knife group 24 and the second knife group 23 and the distance L3 between the second knife group 23 and the third knife group 22 can be avoided, so that the distance between the first knife group 24 and the second knife group 23 is smaller than the distance between the second knife group 23 and the third knife group 22, resulting in the food being stuck between the third bending portion 2421 and the adjacent knife group when passing between the first knife group 24 and the second knife group 23, thereby causing the part of the food to be unable to be further cut, affecting the fineness and taste of the food; at the same time, the distance between the first knife group 24 and the second knife group 23 is larger than the distance between the second knife group 23 and the third knife group 22, resulting in the first knife group 24 and the second knife group 23 being unable to cut more food, resulting in too much food passing over the first knife group 24, resulting in poor food cutting effect and low efficiency.

[0059] Preferably, if Figure 5 As shown, the inner wall of the mixing cup 3 is also provided with a spoiler rib 31, wherein the distance T1 between the spoiler rib 31 and the outermost end of the knife group satisfies: 1mm≤T1<5mm, which effectively prevents the food from sticking to the cup wall and being unable to be whipped; at the same time, the maximum gap T2 between the first knife group 24 and the inner bottom wall of the mixing cup 3 satisfies: 1mm≤T1<5mm, which effectively prevents the food from sticking to the bottom wall of the cup body and being unable to be whipped.

[0060] As a preferred embodiment of the present application, Figure 2 As shown, the first blade 241 extends in an arc shape in the opposite direction of the rotation direction of the stirring blade 2, so that the first bending portion 2411 is located upstream of the second bending portion 2413 in the rotation direction.

[0061] By setting the first blade 241 to extend in an arc shape in the opposite direction of the rotation direction along the stirring blade 2, so that the first bending portion 2411 is located upstream of the rotation direction of the second bending portion 2413, when the first blade 241 rotates, when the food passes through the first blade 241, the food passes through the first bending portion 2411 and moves downward and backward under the action of the first bending portion 2411, and when the food passes through the second bending portion 2413, the food moves forward under the action of the second bending portion 2413, so that the food is moved to the connecting portion 2412 and effectively cut on the cutting surface of the longer connecting portion 2412, thereby further improving the crushing effect.

[0062] It should be noted that the present application does not specifically limit the structure of the knife shaft 21, which can be any one of the following embodiments:

[0063] Embodiment 1: In this embodiment, the blade shaft 21 includes a plastic sleeve, a connecting head 211 arranged above the plastic sleeve, and a shaft sleeve 213 arranged below the plastic sleeve. The plastic sleeve, the connecting head 211 and the shaft sleeve 213 are integrally formed by injection molding.

[0064] By configuring the blade shaft 21 to include a plastic sleeve, a connector 211 disposed above the plastic sleeve, and a shaft sleeve 213 disposed below the plastic sleeve, and the plastic sleeve, the connector 211, and the shaft sleeve 213 are integrally formed by injection molding, the step of connecting and matching the three is omitted, which helps to improve assembly efficiency. At the same time, it helps to improve the coaxiality of the three, ensure the stability of the blade shaft 21 when rotating, and further improve the crushing effect.

[0065] Example 2: Figure 7 As shown, in this embodiment, the blade shaft 21 includes a steel sleeve 212 which is hollow inside and has an opening at the bottom, a shaft sleeve 213 fixed at the opening, and a connecting head 211 fixed above the steel sleeve 212, and the connecting head 211 is made of plastic.

[0066] The blade shaft 21 is configured to include a steel sleeve 212 which is hollow inside and has an opening at the bottom, a shaft sleeve 213 fixed at the opening, and a connector 211 fixed above the steel sleeve 212, and the connector 211 is made of plastic material, which greatly improves the overall strength of the blade shaft 21, effectively avoids deformation during the stirring process, and can be placed in a heated environment to prevent the blade shaft 21 from being dyed and discolored. In addition, the connector 211 made of plastic material can reduce the transfer of heat to the connector 211, thereby effectively avoiding the user from getting hot when holding the connector 211, thereby improving the user experience.

[0067] Furthermore, if Figure 7 As shown, the blade shaft 21 also includes a connecting member 4, which passes through the steel sleeve 212 and is fastened to the connecting head 211, and a sealing member 5 is clamped between the connecting head 211 and the top wall of the steel sleeve 212. Preferably, as shown in FIG. Figure 7 As shown, the bottom wall of the connector 211 is provided with an upwardly concave annular groove 2111 , and the sealing member 5 is a sealing ring fixed in the annular groove 2111 .

[0068] By clamping the sealing member 5 between the connecting head 211 and the top wall of the steel sleeve 212, on the one hand, the stability of the connection between the connecting head 211 and the steel sleeve 212 can be improved to ensure the matching strength of the two; on the other hand, the deformation ability of the sealing member 5 can effectively avoid the situation where the connecting head 211 and the steel sleeve 212 are not properly connected due to assembly and production errors.
