For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0085] Reference will be made below to Figure 1 describe the food processor 1000 according to an embodiment of the present invention.

[0086] The food processor 1000 includes a cup body 200, a cover plate 300, and a main body. Among them, one end of the cup body 200 is open, the blade assembly 100 is located inside the cup body 200, the cover plate 300 is disposed at the open mouth 201 of the cup body 200, the cover plate 300 has a through hole 301 for the tool holder 1 of the blade assembly 100 to extend out, the main machine 400 is disposed on the cover plate 300 or the cup body 200, and the main machine 400 includes a driving mechanism 401. The output shaft of the driving mechanism 401 is connected to the tool holder 1 of the blade assembly 100 extending out of the cup body 200.

[0087] Specifically, when the food processor 1000 needs to cut and stir the material, the material is placed in the stirring space of the cup body 200 from the open mouth 201 of the cup body 200, and the cover plate 300 is disposed at the open mouth 201 of the cup body 200, so that the cover plate 300 and the stirring space cooperate to limit a closed stirring cavity. The driving mechanism 401 drives the tool holder 1 to rotate, so that the material runs from the material receiving end of the blade of the blade assembly 100 to the material discharging end, thereby realizing the cutting and stirring of the material.

[0088] It should be noted that the food processor 1000 can be a household food processing device such as a meat grinder, a wall breaker, and a crusher. Of course, the food processor 1000 of the present embodiment can also be applied to industrial production, for example, applied to the processing and production of materials on a production line. Among them, the materials are not limited to food ingredients, but can also be other materials that need to be processed by cutting.

[0089] Reference will be made below to the blade assembly 100 according to an embodiment of the present invention with reference to the drawings.

[0090] As Figures 1 - 3As shown, the blade assembly 100 includes a tool holder 1 and a tool group 2. Among them, the tool group 2 includes a main body portion 22 and a first blade 21. The main body portion 22 is detachably sleeved on the tool holder 1. The first blade 21 is arranged on the outer peripheral wall of the main body portion 22. The tool group 2 rotates along a first direction with the tool holder 1, and the tool group 2 has a first installation state and a second installation state. The feeding end of the first blade 21 in the first installation state is the discharging end of the first blade 21 in the second installation state.

[0091] It can be understood that by detachably sleeving the main body portion 219 on the tool holder 1, the switching between the first installation state and the second installation state of the tool group 2 is realized. Thus, by making the feeding end of the first blade 21 in the first installation state of the tool group 2 be the discharging end of the first blade 21 in the second installation state, the blade assembly 100 can process the food located in the stirring space in both the first installation state and the second installation state only through one tool group 2, thereby reducing the production cost of the tool group 2 assembly, being convenient for users to store, optimizing the user experience, further enhancing the practicability and reliability of the food processor 1000 applying the blade assembly 100, and improving the product competitiveness. At the same time, by detachably connecting the main body portion 22 and the tool holder 1, it is convenient for users to detach the tool group 2 for cleaning, improving the user experience.

[0092] Compared with the prior art that realizes different processing performances of a food processor by sleeving multiple detachable tool groups on the tool holder respectively, the present invention only needs one tool group 2 to realize different processing performances of the food processor 1000, thereby reducing the production cost, being convenient for users to store, optimizing the user experience, further enhancing the practicability and reliability of the product, and improving the product competitiveness.

[0093] According to the blade assembly 100 of the embodiment of the present invention, the tool group 2 includes a main body portion 22 and a first blade 21. The main body portion 22 is detachably sleeved on the tool holder 1. The first blade 21 is arranged on the outer peripheral wall of the main body portion 22. By rotating the tool group 2 along a first direction with the tool holder 1 and the tool group 2 having a first installation state and a second installation state, the feeding end of the first blade 21 in the first installation state is the discharging end of the first blade 21 in the second installation state, so that the blade assembly 100 can process the food located in the stirring space in both the first installation state and the second installation state only through one tool group 2, thereby reducing the production cost of the tool group 2 assembly, being convenient for users to store, optimizing the user experience, further enhancing the practicability and reliability of the food processor 1000 applying the blade assembly 100, and improving the product competitiveness.

[0094] In some embodiments of the present invention, such as Figure 2 and Figure 3As shown, the two ends of the main body 22 in the length direction are the first end 221 and the second end 222. In the first installation state, the first end 221 is on the side of the second end 222 closer to the tool holder 1. In the second installation state, the second end 222 is on the side of the first end 221 closer to the tool holder 1. Thus, through such a setting, the feeding end of the first blade 21 in the first installation state of the tool group 2 becomes the discharging end of the first blade 21 in the second installation state.

[0095] In some embodiments of the present invention, such as Figure 35 and Figure 36 As shown, the outer peripheral wall of the tool holder 1 has a first engaging portion 11, the main body 22 has an installation cavity 223 for the tool holder 1 to extend into, and the inner wall of the installation cavity 223 has a second engaging portion 2231. In the first installation state and the second installation state, the first engaging portion 11 is engaged with the second engaging portion 2231. Thus, through the cooperation of the first engaging portion 11 and the second engaging portion 2231, the main body 22 is detachably sleeved on the tool holder 1 in the first installation state and the second installation state, thereby realizing two combination methods of the tool holder 1 and the tool group 2.

[0096] In some embodiments of the present invention, such as Figure 35 and Figure 36 As shown, the first engaging portion 11 is a chute, and the second engaging portion 2231 is a protrusion that cooperates with the chute. The chute includes a first groove body 111 and a second groove body 112. The first groove body 111 extends along the circumferential direction of the tool holder 1, and the second groove body 112 extends along the axial direction of the tool holder 1 and one end is connected to one end of the first groove body 111 along the circumferential direction of the tool holder 1, and the other end extends to the axial end surface of the tool holder 1. It can be understood that during the assembly process of the tool holder 1 and the tool group 2, after the protrusion enters the second groove body 112 through the end of the second groove body 112 far from the first groove body 111, the protrusion moves along the axial direction of the tool holder 1 in the second groove body 112 to the connection between the second groove body 112 and the first groove body 111 and enters the first groove body 111. The direction in which the protrusion enters the first groove body 111 is opposite to the first direction, so as to ensure the cooperation between the protrusion and the first groove body 111 when the blade assembly 100 rotates in the first direction, and further ensure the reliability of the blade assembly 100.

[0097] Furthermore, the protrusion is located at the middle position of the inner wall of the installation cavity 223 along the length direction of the installation cavity 223. Thus, through such a setting, the assembly operations of the tool holder 1 and the tool group 2 in the first installation state or the second installation state are the same, which is convenient for the user's operation, improves the user's use experience, and shortens the length of the second groove body 112 along the axial direction of the tool holder 1, ensuring the structural strength of the tool holder 1.

[0098] In some embodiments of the present invention, such as Figure 35 and Figure 36As shown, the first blade 21 includes a body portion 219 and a bent portion 220. The body portion 219 extends in the radial direction of the main body portion 22 and one end thereof is connected to the outer peripheral wall of the main body portion 22. The bent portion 220 extends in the axial direction of the main body portion 22 and one end thereof is connected to the end of the body portion 219 away from the main body portion 22. The bending directions of the bent portion 220 in the first installation state and the second installation state are opposite. Thus, during the process of the first blade 21 cutting and stirring the material, a better whipping effect on the material is achieved through the bent portion 220, and further cutting and stirring of the material are realized, so as to avoid material accumulation as much as possible and ensure that there is no dead angle in the cutting of the material by the first blade 21. At the same time, due to the opposite bending directions of the bent portion 220 in the first installation state and the second installation state, it is beneficial for the user to select the specific installation method of the cutter set 2 according to the requirements or the characteristics of the ingredients, meeting different needs of the user.

[0099] In some embodiments of the present invention, as Figure 35 and Figure 36 shown, the two ends in the length direction of the tool holder 1 are a third end 12 and a fourth end 13. The main body portion 22 is located at the third end 12. In the first installation state, the end of the bent portion 220 away from the body portion 219 extends toward the fourth end 13. It can be understood that in the first installation state, the end of the bent portion 220 away from the body portion 219 extends toward the fourth end 13. During the process of the first blade 21 cutting and stirring the material, the bent portion 220 beats, stirs, tumbles the material, and transports the material toward the fourth end 13, so that the first blade 21 can further cut the material, improving the cutting uniformity. In the second installation state, the end of the bent portion 220 away from the body portion 219 extends toward the third end 12. The bent portion 220 beats, stirs, tumbles the material, and transports the material toward the third end 12, reducing the accumulation of the material at the bottom wall of the cup body 200, so that the first blade 21 can cut the material more fully.

[0100] For example, the third end 12 is the lower end and the fourth end 13 is the upper end. In the first installation state, the end of the bent portion 220 away from the body portion 219 extends upward, so that the first blade 21 helps to squeeze the material clamped between the material and the side wall of the cup body 200, reducing the accumulation of the material on the side wall. In the second installation state, the end of the bent portion 220 away from the body portion 219 extends downward, so that the first blade 21 is beneficial to turn the material at the bottom of the cup body 200 upward, reducing the accumulation of the ingredients.

[0101] In some embodiments of the present invention, as Figure 36As shown, the distance in the axial direction of the main body portion 22 between the surface of the body portion 219 facing away from the bending direction of the bending portion 220 and one end of the bending portion 220 away from the body portion 219 is a, and the distance between the surface of the body portion 219 facing away from the bending direction of the bending portion 220 and the axial end face of the main body portion 22 on the side of the bending direction of the bending portion 220 is b, and it satisfies: a < b. Thus, through such a setting, when the cutter group 2 is in the first installation state and the second installation state, in the axial direction of the main body portion 22, one end of the bending portion 220 away from the body portion 219 does not exceed the axial end face of the main body portion 22 on the side of the bending direction of the bending portion 220, thereby ensuring the reliability of the bending portion 220. When the blade assembly 100 is applied to the food processor 1000, the blade assembly 100 is located in the cup body 200. Through such a setting, it is avoided that the bending portion 220 directly contacts the bottom wall of the cup body 200, ensuring the reliability of the operation of the blade assembly 100.

[0102] In some embodiments of the present invention, as Figure 2 and Figure 3 shown, both ends of the first blade 21 in the circumferential direction of the main body portion 22 have a first cutting edge 211 and a second cutting edge 212. The edge thickness of the first cutting edge 211 is different from the edge thickness of the second cutting edge 212. In the first installation state, the first cutting edge 211 is located at the material receiving end of the first blade 21. In the second installation state, the second cutting edge 212 is located at the material receiving end of the first blade 21.

[0103] It can be understood that since the edge thickness of the first cutting edge 211 is different from the edge thickness of the second cutting edge 212, the cutting effects of the first cutting edge 211 and the second cutting edge 212 on the material are different. Thus, by switching the cutter group 2 between the first installation state and the second installation state, the first cutting edge 211 or the second cutting edge 212 with different edge thicknesses is located at the material receiving end of the first blade 21, thereby achieving different cutting and stirring effects on the material through one cutter group 2.

[0104] For example, the edge thickness of the first cutting edge 211 is greater than the edge thickness of the second cutting edge 212. When the cutter group 2 is in the first installation state, through the material receiving end of the first blade 21 being the first cutting edge 211 with a relatively thick edge thickness, sufficient beating, stirring, and tumbling of the material are achieved to make large-particle food ingredients. When the cutter group 2 is in the second installation state, through the material receiving end of the first blade 21 being the second cutting edge 212 with a relatively thin edge thickness, rapid pulverization of the material is achieved.

[0105] In some embodiments of the present invention, the edge thickness of the first cutting edge 211 is T1, the edge thickness of the second cutting edge 212 is T2, and the thickness of the first blade 21 is H1, where 0.15 mm ≤ T1 < H1 and 0 < T2 < 0.15 mm. It can be understood that the edge thickness of the first cutting edge 211 can be any value between 0.15 or 0.15 mm and the thickness of the first blade 21, and the edge thickness of the second cutting edge 212 can be 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 0.10, 0.11, 0.12, 0.13, or 0.14. Thus, through such a setting, it is ensured that the edge thickness of the first cutting edge 211 is different from that of the second cutting edge 212, and the first cutting edge 211 is a blunt edge while the second cutting edge 212 is a sharp edge.

[0106] In some embodiments of the present invention, as Figures 4 - 3 shown, the blade assembly 100 further includes a second blade 3. The second blade 3 and the first blade 21 are spaced apart both in the axial direction and the circumferential direction of the tool holder 1. Thus, during the process of the blade assembly 100 cutting and stirring the material, the feeding end of the first blade 21 in the first installation state is the discharging end of the first blade 21 in the second installation state, and the combination of the first blade 21 and the second blade 3 achieves various processing effects on the material, improving the practicability of the blade assembly 100. At the same time, by spacing the second blade 3 and the first blade 21 both in the axial direction and the circumferential direction of the tool holder 1, the cutting and stirring effect of the first blade 21 and the second blade 3 on the material is improved, thereby improving the processing effect of the blade assembly 100 on the material.

[0107] In some embodiments of the present invention, as Figure 4 shown, the second blade 3 has a different shape from the first blade 21. Thus, by having the second blade 3 with a different shape from the first blade 21, the processing effects of the second blade 3 and the second blade 3 on the material are different, and further various processing effects on the material are achieved through the combination of the first blade 21 and the second blade 3, improving the practicability of the blade assembly 100

[0108] In some embodiments of the present invention, as Figure 4 shown, both ends of the second blade 3 in the circumferential direction of the tool holder 1 are arcs protruding in the same direction in the circumferential direction of the main body portion 22. Thus, through such a setting, when the second blade 3 rotates, it can better form a converging circular flow form, reduce resistance, and perform uniform circular motion around a certain fixed point and converge towards the center, thereby greatly improving the cutting effect of the second blade 3 on the material, and further effectively reducing the power of the motor of the driving mechanism 401 of the food processor 1000, reducing costs, and enhancing product competitiveness.

[0109] In some embodiments of the present invention, asFigures 4 - 27 As shown, at least one end of the first blade 21 has a cutting edge at both ends in the circumferential direction of the tool holder 1, and at least one end of the second blade 3 has a cutting edge at both ends in the circumferential direction of the tool holder 1. It can be understood that both ends of the first blade 21 in the circumferential direction of the tool holder 1 have cutting edges and the edge thicknesses of the two cutting edges are different, or, one end of the first blade 21 in the circumferential direction of the tool holder 1 has a cutting edge and the other is without a cutting edge; both ends of the second blade 3 in the circumferential direction of the tool holder 1 have cutting edges and the edge thicknesses of the two cutting edges are different, or, one end of the second blade 3 in the circumferential direction of the tool holder 1 has a cutting edge and the other is without a cutting edge. Thus, by making the feeding end of the first blade 21 in the first installation state be the discharging end of the first blade 21 in the second installation state, different combinations of the cutting edges at the feeding ends of the first blade 21 and the second blade 3 are realized, achieving various processing effects on the material by the blade assembly 100 and improving the practicability of the blade assembly 100.

[0110] In some embodiments of the present invention, as Figure 4 and Figure 5 shown, one end of the first blade 21 in the circumferential direction of the tool holder 1 has a third cutting edge 213 and the other end is without a cutting edge, one end of the second blade 3 in the circumferential direction of the tool holder 1 has a fourth cutting edge 31 and the other end is without a cutting edge. In the first installation state, the third cutting edge 213 is located at the feeding end of the first blade 21, and the fourth cutting edge 31 is located at the discharging end of the second blade 3. In the second installation state, the third cutting edge 213 is located at the discharging end of the first blade 21, and the fourth cutting edge 31 is located at the feeding end of the second blade 3. The edge thickness of the third cutting edge 213 is different from the edge thickness of the fourth cutting edge 31.

[0111] Thus, when the blade assembly 100 rotates in the first direction and the tool group 2 is in the first installation state, the combination of the third cutting edge 213 being located at the feeding end of the first blade 21 and the non-cutting edge being located at the feeding end of the second blade 3 is realized. The non-cutting edge is used to slap and stir and tumble the material to make the material mix evenly, and the third cutting edge 213 of the first blade 21 can perform better cutting to improve the uniformity of material crushing. When the tool group 2 rotates in the first direction and the tool group 2 is in the second installation state, the combination of the non-cutting edge being located at the feeding end of the first blade 21 and the fourth cutting edge 31 being located at the feeding end of the second blade 3 is realized. The non-cutting edge is used to slap and stir and tumble the material to make the material mix evenly, and the fourth cutting edge 31 of the second blade 3 can perform better cutting to improve the uniformity of material crushing.

[0112] Meanwhile, by making the edge thickness of the third blade 213 different from that of the fourth blade 31, the edge thickness of the blades at the material feeding end of the cutter group 2 in the first installation state and the second installation state is different, so that different cutting and stirring effects on the material can be achieved by one cutter group 2. For example, the edge thickness of the third blade 213 is greater than that of the fourth blade 31. In the first installation state of the cutter group 2, the material feeding end of the first blade 21 is the third blade 213 with a relatively thick edge thickness, which can fully pat, stir and tumble the material, and the non-edge of the second blade 3 can also pat, stir and tumble the material, so as to make large-particle food materials, and further achieve one of the processing effects of the blade assembly 100 on the material; in the second installation state of the cutter group 2, the material feeding end of the second blade 3 is the fourth blade 31 with a relatively thin edge thickness, and the non-edge of the second blade 3 can pat, stir and tumble the material, so as to quickly crush the material, and further achieve one of the processing effects of the blade assembly 100 on the material.

[0113] In some embodiments of the present invention, the edge thickness of the third blade 213 is T1, the edge thickness of the fourth blade 31 is T2, and the thicknesses of the third blade and the fourth blade are the same, both being H1, where 0.15 mm ≤ T1 < H1 and 0 < T2 < 0.15 mm. Thus, through such a setting, it is ensured that the edge thickness of the third blade 213 is different from that of the fourth blade 31, and the third blade 213 is a blunt edge while the fourth blade 31 is a sharp edge.

[0114] In some embodiments of the present invention, as Figures 6 - 13 shown, both ends of the first blade 21 in the circumferential direction of the tool holder 1 respectively have a fifth blade 214 and a sixth blade 215, one end of the second blade 3 in the circumferential direction of the tool holder 1 has a seventh blade 32, and the other end has no edge. The edge thickness of the fifth blade 214 is equal to that of the seventh blade 32, and the edge thickness of the fifth blade 214 is greater than or less than that of the sixth blade 215.

[0115] Thus, the material feeding end of the first blade 21 in the first installation state of the cutter group 2 is the material discharging end of the first blade 21 in the second installation state, and the first blade 21 has a fifth blade 214 and a sixth blade 215, and the second blade 3 has a seventh blade 32, so as to realize different combinations of the blades at the material feeding ends of the first blade 21 and the second blade 3, achieve multiple processing effects of the blade assembly 100 on the material, and improve the practicability of the blade assembly 100.

[0116] In some embodiments of the present invention, as Figures 6 - 9 shown, in the first installation state, the fifth blade 214 is located at the material feeding end of the first blade 21, in the second installation state, the sixth blade 215 is located at the material feeding end of the first blade 21, and the seventh blade 32 is located at the material feeding end of the second blade 3.

[0117] It can be understood that, as Figure 6 shown, when the edge thickness of the fifth blade 214 is greater than that of the sixth blade 215, and the blade assembly 100 rotates in the first direction and the cutter group 2 is in the first installation state, a combination is achieved where the fifth blade 214 is located at the material receiving end of the first blade 21 and the non-edge is located at the material receiving end of the second blade 3. Thus, through the material receiving end of the first blade 21, the fifth blade 214 with a relatively thick edge thickness can fully beat, stir, and tumble the material, and the non-edge can beat, stir, and tumble the material, realizing the production of large particle food materials, and further realizing one of the processing effects of the blade assembly 100 on the material; as Figure 7 shown, when the blade assembly 100 rotates in the first direction and the cutter group 2 is in the second installation state, a combination is achieved where the sixth blade 215 is located at the material receiving end of the first blade 21 and the seventh blade 32 is located at the material receiving end of the second blade 3. And through the material receiving end of the first blade 21 for the sixth blade 215 with a relatively thin edge thickness and the material receiving end of the second blade 3 for the seventh blade 32 with a relatively thick edge thickness, thus the second blade 3 can fully beat and stir the material and the first blade 21 can fully cut the material to improve the uniformity of material crushing, and further realize one of the processing effects of the blade assembly 100 on the material.

[0118] Furthermore, the edge thickness of the fifth blade 214 is T1, the edge thickness of the sixth blade 215 is T2, and the thickness of the first blade 21 is H1, where 0.15mm ≤ T1 < H1 and 0 < T2 < 0.15mm. Thus, through such a setting, it is ensured that the edge thickness of the fifth blade 214 is different from that of the sixth blade 215, and the fifth blade 214 is a blunt edge while the sixth blade 215 is a sharp edge.

[0119] As Figure 8 shown, when the edge thickness of the fifth blade 214 is less than that of the sixth blade 215, and the blade assembly 100 rotates in the first direction and the cutter group 2 is in the first installation state, a combination is achieved where the fifth blade 214 is located at the material receiving end of the first blade 21 and the non-edge is located at the material receiving end of the second blade 3. Thus, through the material receiving end of the first blade 21, the fifth blade 214 with a relatively thin edge thickness can fully cut the material and the non-edge can beat, stir, and tumble the material, improving the uniformity of material crushing, and further realizing one of the processing effects of the blade assembly 100 on the material; as Figure 9As shown, when the blade assembly 100 rotates in the first direction and the cutter group 2 is in the second installation state, a combination is achieved where the sixth cutting edge 215 is located at the material feeding end of the first blade 21 and the seventh cutting edge 32 is located at the material feeding end of the second blade 3. The material feeding end of the first blade 21 serves as the cutting edge for the sixth cutting edge 215 with a relatively thick edge thickness, and the material feeding end of the second blade 3 serves as the cutting edge for the seventh cutting edge 32 with a relatively thin edge thickness. Thus, the first blade 21 can fully beat and stir the material, and the second blade 3 can fully cut the material, improving the uniformity of material crushing, and further achieving one of the processing effects of the blade assembly 100 on the material.

[0120] Further, the edge thickness of the sixth cutting edge 215 is T1, the edge thickness of the fifth cutting edge 214 is T2, and the thickness of the first blade is H1, where 0.15 mm ≤ T1 < H1 and 0 < T2 < 0.15 mm. Thus, such a setting ensures that the edge thickness of the fifth cutting edge 214 is different from that of the sixth cutting edge 215, and the sixth cutting edge 215 is a blunt edge while the fifth cutting edge 214 is a sharp edge.

[0121] In some embodiments of the present invention, as Figures 10 - 13 shown, in the first installation state, the sixth cutting edge 215 is located at the material feeding end of the first blade 21. In the second installation state, the fifth cutting edge 214 is located at the material feeding end of the first blade 21, and the seventh cutting edge 32 is located at the material feeding end of the second blade 3.

[0122] As Figure 10 shown, when the edge thickness of the fifth cutting edge 214 is greater than that of the sixth cutting edge 215, when the blade assembly 100 rotates in the first direction and the cutter group 2 is in the first installation state, a combination is achieved where the sixth cutting edge 215 is located at the material feeding end of the first blade 21 and there is no cutting edge at the material feeding end of the second blade 3. Thus, the material feeding end of the first blade 21 can fully cut the material with the relatively thin-edge sixth cutting edge 215, and the non-cutting edge can beat, stir, and tumble the material, improving the uniformity of material crushing, and further achieving one of the processing effects of the blade assembly 100 on the material; as Figure 11 shown, when the blade assembly 100 rotates in the first direction and the cutter group 2 is in the second installation state, a combination is achieved where the fifth cutting edge 214 is located at the material feeding end of the first blade 21 and the seventh cutting edge 32 is located at the material feeding end of the second blade 3. The material feeding end of the first blade 21 serves as the cutting edge for the relatively thick-edge fifth cutting edge 214, and the material feeding end of the second blade 3 serves as the cutting edge for the relatively thick-edge seventh cutting edge 32. Thus, both the first blade 21 and the second blade 3 can fully beat and stir the material, achieving the production of large-particle food ingredients, and further achieving one of the processing effects of the blade assembly 100 on the material.

[0123] Furthermore, the edge thickness of the fifth blade 214 is T1, the edge thickness of the sixth blade 215 is T2, and the thickness of the first blade 21 is H1, where 0.15 mm ≤ T1 < H1 and 0 < T2 < 0.15 mm. Thus, such a setting ensures that the edge thickness of the fifth blade 214 is different from that of the sixth blade 215, and the fifth blade 214 is a blunt edge while the sixth blade 215 is a sharp edge.

[0124] As Figure 12 shown, when the edge thickness of the fifth blade 214 is less than that of the sixth blade 215 and the blade assembly 100 rotates in the first direction and the cutter group 2 is in the first installation state, a combination is achieved where the sixth blade 215 is located at the material feeding end of the first blade 21 and the non-edge is located at the material feeding end of the second blade 3. Thus, the material feeding end of the first blade 21, with the relatively thicker-edge sixth blade 215, can fully beat, stir, and tumble the material, and the non-edge can also beat and stir-tumble the material, realizing the production of large particle ingredients, and further achieving one of the processing effects of the blade assembly 100 on the material; As Figure 13 shown, when the blade assembly 100 rotates in the first direction and the cutter group 2 is in the second installation state, a combination is achieved where the fifth blade 214 is located at the material feeding end of the first blade 21 and the seventh blade 32 is located at the material feeding end of the second blade 3. And with the relatively thinner-edge fifth blade 214 at the material feeding end of the first blade 21 and the relatively thinner-edge seventh blade 32 at the material feeding end of the second blade 3, the material can be fully cut by the first blade 21 and the second blade 3 to improve the uniformity of material crushing, and further achieve one of the processing effects of the blade assembly 100 on the material.

[0125] Furthermore, the edge thickness of the sixth blade 215 is T1, the edge thickness of the fifth blade 214 is T2, and the thickness of the fifth first blade is H1, where 0.15 mm ≤ T1 < H1 and 0 < T2 < 0.15 mm. Thus, such a setting ensures that the edge thickness of the fifth blade 214 is different from that of the sixth blade 215, and the sixth blade 215 is a blunt edge while the fifth blade 214 is a sharp edge.

[0126] In some embodiments of the present invention, as Figures 14 - 21 shown, one end of the first blade 21 in the circumferential direction of the tool holder 1 has an eighth blade 216 and the other end is non-edge. The two ends of the second blade 3 in the circumferential direction of the tool holder 1 respectively have a ninth blade 33 and a tenth blade 34. The edge thickness of the eighth blade 216 is equal to that of the ninth blade 33, and the edge thickness of the ninth blade 33 is greater than or less than that of the tenth blade 34.

[0127] Thus, the material-feeding end of the first blade 21 in the first installation state of the cutter group 2 is the material-discharging end of the first blade 21 in the second installation state, and the first blade 21 has an eighth cutting edge 216, and the second blade 3 has a ninth cutting edge 33 and a tenth cutting edge 34. Thus, different combinations of the cutting edges at the material-feeding ends of the first blade 21 and the second blade 3 are realized, and various processing effects on the material by the blade assembly 100 are achieved, improving the practicability of the blade assembly 100.

[0128] In some embodiments of the present invention, as Figures 14 - 17 shown, in the first installation state, the eighth cutting edge 216 is located at the material-feeding end of the first blade 21, and the ninth cutting edge 33 is located at the material-feeding end of the second blade 3. In the second installation state, the tenth cutting edge 34 is located at the material-feeding end of the second blade 3.

[0129] It can be understood that, as Figure 14 shown, when the edge thickness of the ninth cutting edge 33 is greater than the edge thickness of the tenth cutting edge 34, when the blade assembly 100 rotates in the first direction and the cutter group 2 is in the first installation state, the eighth cutting edge 216 is located at the material-feeding end of the first blade 21 and the ninth cutting edge 33 is located at the material-feeding end of the second blade 3, and the material-feeding end of the first blade 21 is the eighth cutting edge 216 with a relatively thin edge thickness and the material-feeding end of the second blade 3 is the ninth cutting edge 33 with a relatively thick edge thickness. Thus, through the full cutting of the material by the first blade 21 and the full beating and stirring of the material by the second blade 3, the full cutting of the material is realized, and thus one of the processing effects of the blade assembly 100 on the material is achieved; as Figure 15 shown, when the blade assembly 100 rotates in the first direction and the cutter group 2 is in the second installation state, it is realized that there is no cutting edge at the material-feeding end of the first blade 21 and the tenth cutting edge 34 is located at the material-feeding end of the second blade 3. Thus, through the tenth cutting edge 34 with a relatively thin edge thickness at the material-feeding end of the second blade 3, the full cutting of the material is realized, and the function of beating and stirring and tumbling the material without a cutting edge is realized, improving the uniformity of material crushing, and thus one of the processing effects of the blade assembly 100 on the material is achieved.

[0130] Further, the edge thickness of the ninth cutting edge 33 is T1, the edge thickness of the tenth cutting edge 34 is T2, and the thickness of the first blade 21 is H1, where 0.15 mm ≤ T1 < H1 and 0 < T2 < 0.15 mm. Thus, through such a setting, it is ensured that the edge thickness of the ninth cutting edge 33 is different from the edge thickness of the tenth cutting edge 34, and the ninth cutting edge 33 is a blunt edge and the tenth cutting edge 34 is a sharp edge.

[0131] As Figure 16As shown, when the edge thickness of the ninth blade 33 is less than that of the tenth blade 34, and the blade assembly 100 rotates in the first direction and the cutter group 2 is in the first installation state, the eighth blade 216 is located at the material receiving end of the first blade 21 and the ninth blade 33 is located at the material receiving end of the second blade 3. The material receiving end of the first blade 21 serves as the eighth blade 216 with a relatively thick edge thickness and the material receiving end of the second blade 3 serves as the ninth blade 33 with a relatively thin edge thickness. Thus, the first blade 21 realizes stirring and patting of the material, and the second blade 3 realizes sufficient cutting of the material, thereby realizing one of the processing effects of the blade assembly 100 on the material; as Figure 17 As shown, when the blade assembly 100 rotates in the first direction and the cutter group 2 is in the second installation state, there is no edge at the material receiving end of the first blade 21 and the tenth blade 34 is located at the material receiving end of the second blade 3. Thus, the material receiving end of the second blade 3 serves as the tenth blade 34 with a relatively thick edge thickness to realize sufficient cutting of the material, and the absence of an edge realizes the functions of patting, stirring, and tumbling of the material, realizing the production of large-particle food materials, and further realizing one of the processing effects of the blade assembly 100 on the material.

[0132] Furthermore, the edge thickness of the tenth blade 34 is T1, the edge thickness of the ninth blade 33 is T2, and the thickness of the first blade 21 is H1, where 0.15 mm ≤ T1 < H1 and 0 < T2 < 0.15 mm. Thus, through such a setting, it is ensured that the edge thickness of the ninth blade 33 is different from that of the tenth blade 34, and the tenth blade 34 is a blunt blade while the ninth blade 33 is a sharp blade.

[0133] In some embodiments of the present invention, as Figures 18 - 21 shown, in the first installation state, the eighth blade 216 is located at the material receiving end of the first blade 21 and the tenth blade 34 is located at the material receiving end of the second blade 3. In the second installation state, the ninth blade 33 is located at the material receiving end of the second blade 3.

[0134] It can be understood that, as Figure 18 shown, when the edge thickness of the ninth blade 33 is greater than that of the tenth blade 34, and the blade assembly 100 rotates in the first direction and the cutter group 2 is in the first installation state, the eighth blade 216 is located at the material receiving end of the first blade 21 and the tenth blade 34 is located at the material receiving end of the second blade 3. The material receiving end of the first blade 21 serves as the eighth blade 216 with a relatively thick edge thickness and the material receiving end of the second blade 3 serves as the tenth blade 34 with a relatively thin edge thickness. Thus, the first blade 21 realizes sufficient patting and stirring of the material and the second blade 3 realizes sufficient cutting of the material to improve the uniformity of material crushing, and further realizes one of the processing effects of the blade assembly 100 on the material; as Figure 19As shown, when the blade assembly 100 rotates in the first direction and the knife group 2 is in the second installation state, the edgeless portion is located at the material-facing end of the first blade 21 and the ninth blade 33 is located at the material-facing end of the second blade 3, so that the material is beaten, stirred and tumbled by the ninth blade 33 having a relatively thick blade edge at the material-facing end of the second blade 3, and the material is beaten, stirred and tumbled by the edgeless portion, so as to realize the production of large-particle food materials, thereby realizing one of the processing effects of the blade assembly 100 on the material.

[0135] Furthermore, the edge thickness of the ninth blade 33 is T1, the edge thickness of the tenth blade 34 is T2, and the thickness of the first blade 21 is H1, wherein 0.15 mm ≤ T1

[0136] like Figure 20 As shown, when the edge thickness of the ninth blade 33 is less than the edge thickness of the tenth blade 34, the blade assembly 100 rotates along the first direction and the knife group 2 is in the first installation state, so that the eighth blade 216 is located at the material-facing end of the first blade 21 and the tenth blade 34 is located at the material-facing end of the second blade 3, and the material-facing end of the first blade 21 is the eighth blade 216 with a relatively thin edge thickness and the material-facing end of the second blade 3 is the tenth blade 34 with a relatively thick edge thickness, so that the material is fully cut by the eighth blade 216 with a relatively thin edge thickness at the material-facing end of the first blade 21 and the tenth blade 34 with a relatively thick edge thickness at the material-facing end of the second blade 3 is used to beat and stir the material, thereby improving the uniformity of material crushing, and thereby achieving one of the processing effects of the blade assembly 100 on the material; as Figure 21 As shown, when the blade assembly 100 rotates in the first direction and the knife group 2 is in the second installation state, the edgeless blade is located at the material-facing end of the first blade 21 and the ninth blade 33 is located at the material-facing end of the second blade 3, so that the material is fully cut by the ninth blade 33 with a relatively thin blade thickness at the material-facing end of the second blade 3, and the material is beaten, stirred and tumbled without an edge, thereby improving the uniformity of material crushing, and further achieving one of the processing effects of the blade assembly 100 on the material.

[0137] Furthermore, the edge thickness of the tenth blade 34 is T1, the edge thickness of the ninth blade 33 is T2, and the thickness of the first blade 21 is H1, wherein 0.15 mm ≤ T1

[0138] ​​In some embodiments of the present invention, as Figures 22 - 27 shown, at both ends of the first blade 21 along the circumferential direction of the tool holder 1, there are an eleventh cutting edge 217 and a twelfth cutting edge 218 respectively. At both ends of the second blade 3 along the circumferential direction of the tool holder 1, there are a thirteenth cutting edge 35 and a fourteenth cutting edge 36 respectively. The edge thickness of the eleventh cutting edge 217 is equal to the edge thickness of the thirteenth cutting edge 35, the edge thickness of the twelfth cutting edge 218 is equal to the edge thickness of the fourteenth cutting edge 36, and the edge thickness of the thirteenth cutting edge 35 is less than the edge thickness of the fourteenth cutting edge 36.

[0139] It can be understood that the eleventh cutting edge 217 and the thirteenth cutting edge 35 are sharp edges, and the twelfth cutting edge 218 and the fourteenth cutting edge 36 are blunt edges. Thus, the material feeding end of the first blade 21 in the first installation state is the material discharging end of the first blade 21 in the second installation state, and the first blade 21 has sharp and blunt edges, and the second blade 3 has sharp and blunt edges, so as to realize different combinations of the cutting edges at the material feeding ends of the first blade 21 and the second blade 3, achieve various processing effects on the material by the blade assembly 100, and improve the practicability of the blade assembly 100.

[0140] Furthermore, the edge thickness of the twelfth cutting edge 218 is T1, the edge thickness of the eleventh cutting edge 217 is T2, and the thickness of the first blade 21 is H1, where 0.15 mm ≤ T1 < H1 and 0 < T2 < 0.15 mm. Thus, through such a setting, it is ensured that the edge thickness of the eleventh cutting edge 217 is different from the edge thickness of the twelfth cutting edge 218, and the twelfth cutting edge 218 is a blunt edge while the eleventh cutting edge 217 is a sharp edge.

[0141] The edge thickness of the fourteenth cutting edge 36 is T1, the edge thickness of the thirteenth cutting edge 35 is T2, and the thickness of the second blade 3 is H1, where 0.15 mm ≤ T1 < H1 and 0 < T2 < 0.15 mm. Thus, through such a setting, it is ensured that the edge thickness of the thirteenth cutting edge 35 is different from the edge thickness of the fourteenth cutting edge 36, and the fourteenth cutting edge 36 is a blunt edge while the thirteenth cutting edge 35 is a sharp edge.

[0142] In some embodiments of the present invention, as Figure 22 and Figure 23 shown, in the first installation state, the eleventh cutting edge 217 is located at the material feeding end of the first blade 21, and the fourteenth cutting edge 36 is located at the material feeding end of the second blade 3. In the second installation state, the twelfth cutting edge 218 is located at the material feeding end of the first blade 21, and the thirteenth cutting edge 35 is located at the material feeding end of the second blade 3.

[0143] It can be understood that, as Figure 22As shown, when the blade assembly 100 rotates in the first direction and the cutter group 2 is in the first installation state, the eleventh cutting edge 217 is located at the material feeding end of the first blade 21 and the fourteenth cutting edge 36 is located at the material feeding end of the second blade 3. The sharp edge fully cuts the material at the material feeding end of the first blade 21, and the blunt edge fully pats and stirs the material at the material feeding end of the second blade 3 to improve the uniformity of material crushing, thereby achieving one of the processing effects of the blade assembly 100 on the material; as Figure 23 As shown, when the blade assembly 100 rotates in the first direction and the cutter group 2 is in the second installation state, the twelfth cutting edge 218 is located at the material feeding end of the first blade 21 and the thirteenth cutting edge 35 is located at the material feeding end of the second blade 3. The sharp edge fully cuts the material at the material feeding end of the second blade 3, and the blunt edge fully pats and stirs the material at the material feeding end of the first blade 21 to improve the uniformity of material crushing, thereby achieving one of the processing effects of the blade assembly 100 on the material.

[0144] In some embodiments of the present invention, such as Figure 24 and Figure 25 As shown, in the first installation state, the eleventh cutting edge 217 is located at the material feeding end of the first blade 21, and the thirteenth cutting edge 35 is located at the material feeding end of the second blade 3. In the second installation state, the twelfth cutting edge 218 is located at the material feeding end of the first blade 21, and the fourteenth cutting edge 36 is located at the material feeding end of the second blade 3.

[0145] It can be understood that, as Figure 24 As shown, when the blade assembly 100 rotates in the first direction and the cutter group 2 is in the first installation state, the eleventh cutting edge 217 is located at the material feeding end of the first blade 21 and the thirteenth cutting edge 35 is located at the material feeding end of the second blade 3. The sharp edge fully cuts the material at the material feeding end of the first blade 21 and the sharp edge fully cuts the material at the material feeding end of the second blade 3, thereby achieving one of the processing effects of the blade assembly 100 on the material; as Figure 25 As shown, when the blade assembly 100 rotates in the second direction and the cutter group 2 is in the first installation state, the twelfth cutting edge 218 is located at the material feeding end of the first blade 21 and the fourteenth cutting edge 36 is located at the material feeding end of the second blade 3. The blunt edge pats and stirs and tumbles the material at the material feeding end of the first blade 21 and the blunt edge pats and stirs and tumbles the material at the material feeding end of the second blade 3 to make large particle food materials, thereby achieving one of the processing effects of the blade assembly 100 on the material.

[0146] In some embodiments of the present invention, such as Figure 26 and Figure 27As shown, in the first installation state, the twelfth blade 218 is located at the material receiving end of the first blade 21, and the fourteenth blade 36 is located at the material receiving end of the second blade 3. In the second installation state, the eleventh blade 217 is located at the material receiving end of the first blade 21, and the thirteenth blade 35 is located at the material receiving end of the second blade 3.

[0147] It can be understood that, as Figure 26 shown, when the blade assembly 100 rotates in the first direction and the cutter group 2 is in the first installation state, the twelfth blade 218 is located at the material receiving end of the first blade 21, and the fourteenth blade 36 is located at the material receiving end of the second blade 3. By using the dull edge at the material receiving end of the first blade 21 and the dull edge at the material receiving end of the second blade 3, the functions of patting and stirring and tumbling the material are realized, the production of large particle food materials is achieved, and thus one of the processing effects of the blade assembly 100 on the material is realized; as Figure 27 shown, when the blade assembly 100 rotates in the first direction and the cutter group 2 is in the second installation state, the eleventh blade 217 is located at the material receiving end of the first blade 21 and the thirteenth blade 35 is located at the material receiving end of the second blade 3. By using the sharp edge at the material receiving end of the first blade 21 and the sharp edge at the material receiving end of the second blade 3, the sufficient cutting of the material is realized, and thus one of the processing effects of the blade assembly 100 on the material is realized.

[0148] In some embodiments of the present invention, as Figures 28 - 31 shown, the second blade 3 is arranged on the outer peripheral wall of the main body portion 22 or the outer peripheral wall of the tool holder 1, and the second blade 3 and the first blade 21 are spaced apart both in the axial direction and the circumferential direction of the tool holder 1.

[0149] It can be understood that, as Figure 28 and Figure 29 shown, when the second blade 3 is arranged on the outer peripheral wall of the main body portion 22 and the first blade 21 is arranged on the outer peripheral wall of the main body portion 22, both the first blade 21 and the second blade 3 rotate in the first direction and the cutter group 2 has a first installation state and a second installation state. The material receiving end of the first blade 21 in the first installation state is the material discharging end of the first blade 21 in the second installation state, and the material receiving end of the second blade 3 in the first installation state is the material discharging end of the second blade 3 in the second installation state. Thus, through such a setting, it is realized that only one cutter group 2 can process the food located in the stirring space both in the first installation state and the second installation state, and by making the blade thicknesses at both ends of the first blade 21 in the circumferential direction of the tool holder 1 different from the blade thicknesses at both ends of the second blade 3 in the circumferential direction of the tool holder 1, different processing effects of the blade assembly 100 on the material are realized.

[0150] Or, as Figure 30 and Figure 31As shown, when the second blade 3 is provided on the outer peripheral wall of the tool holder 1 and the first blade 21 is provided on the outer peripheral wall of the main body portion 22, the first blade 21 rotates in the first direction and the tool group 2 has a first installation state and a second installation state. The material receiving end of the first blade 21 in the first installation state is the material discharging end of the first blade 21 in the second installation state, and the material receiving end of the second blade 3 is always fixed. Thus, by the fixing treatment effect of the second blade 3 on the material and the treatment effects of the tool group 2 in the first installation state and the second installation state, different treatment effects of the blade assembly 100 on the material are achieved.

[0151] Furthermore, the material receiving end of the second blade 3 is a sharp edge or a blunt edge, and the other end has no edge. Thus, when the material receiving end of the second blade 3 is a sharp edge, when the tool holder 1 rotates in the first direction, the second blade 3 achieves sufficient cutting of the material; when the material receiving end of the second blade 3 is a blunt edge, when the tool holder 1 rotates in the first direction, the second blade 3 achieves stirring and beating of the material and transports the material downward. At the same time, since the material discharging end of the second blade 3 has no edge, the processing of the second blade 3 is reduced and the cost is lowered.

[0152] At the same time, since the second blade 3 and the first blade 21 are spaced apart in both the axial direction and the circumferential direction of the tool holder 1, when the second blade 3 is provided on the outer peripheral wall of the main body portion 22 or the outer peripheral wall of the tool holder 1, the cutting and stirring effects of the first blade 21 and the second blade 3 on the material are improved, thereby improving the treatment effect of the blade assembly 100 on the material.

[0153] In some embodiments of the present invention, as Figures 28 - 31 shown, there is one first blade 21 and multiple second blades 3. The multiple second blades 3 are all spaced apart in both the axial direction and the circumferential direction of the tool holder 1, and the multiple second blades 3 are all located on the same side of the first blade 21 in the axial direction of the tool holder 1.

[0154] It can be understood that by setting one first blade 21 and multiple second blades 3, and the multiple second blades 3 are all spaced apart in both the axial direction and the circumferential direction of the tool holder 1, the treatment effect of the blade assembly 100 on the material is improved. At the same time, since the multiple second blades 3 are all located on the same side of the first blade 21 in the axial direction of the tool holder 1, when the tool holder 1 rotates in the first direction, after the multiple second blades 3 all process the material, the first blade 21 processes the material, or, after the first blade 21 processes the material, the multiple second blades 3 process the material in sequence, further ensuring the treatment effect of the blade assembly 100 on the material.

[0155] Further, when the second blade 3 is provided on the outer peripheral wall of the main body portion 22, the first blade 21 includes a main body portion 219 and a bent portion 220. The main body portion 219 extends in the radial direction of the main body portion 22 and one end thereof is connected to the outer peripheral wall of the main body portion 22. The bent portion 220 extends in the axial direction of the main body portion 22 and one end thereof is connected to the end of the main body portion 219 away from the main body portion 22. The end of the bent portion 220 away from the main body portion 219 extends toward the second blade 3. Both ends of the second blade 3 in the circumferential direction of the tool holder 1 are arcs protruding in the same direction in the circumferential direction of the main body portion 22. Thus, in the first installation state, a plurality of second blades 3 are located above the first blade 21. When the tool holder 1 rotates in the first direction, after the material is cut by the plurality of second blades 3, the material clamped between the material and the side wall of the cup body 200 is extruded by the first blade 21, reducing the accumulation of the material on the side wall. In the second installation state, a plurality of second blades 3 are located below the first blade 21. When the tool holder 1 rotates in the first direction, first, the first blade 21 stirs and throws the material downward to transport it so that the plurality of second blades 3 can cut the material sufficiently.

[0156] Alternatively, when the second blade 3 is provided on the outer peripheral wall of the tool holder 1, the first blade 21 includes a main body portion 219 and a bent portion 220. The main body portion 219 extends in the radial direction of the main body portion 22 and one end thereof is connected to the outer peripheral wall of the main body portion 22. The bent portion 220 extends in the axial direction of the main body portion 22 and one end thereof is connected to the end of the main body portion 219 away from the main body portion 22. The bending directions of the bent portion 220 in the first installation state and the second installation state are opposite. Both ends of the second blade 3 in the circumferential direction of the tool holder 1 are arcs protruding in the same direction in the circumferential direction of the main body portion 22. Thus, in the first installation state, the end of the bent portion 220 away from the main body portion 219 extends upward, so that the first blade 21 helps to extrude the material clamped between the material and the side wall of the cup body 200, reducing the accumulation of the material on the side wall. In the second installation state, the end of the bent portion 220 away from the main body portion 219 extends downward, so that the first blade 21 is conducive to turning up the material at the bottom of the cup body 200, reducing the accumulation of the ingredients, so that the plurality of second blades 3 can cut the material more sufficiently.

[0157] In some embodiments of the present invention, as Figures 32 - 33 shown, there are a plurality of second blades 3. Some of the second blades 3 are provided on the outer peripheral wall of the main body portion 22, and the other part of the second blades 3 are provided on the outer peripheral wall of the tool holder 1. The plurality of second blades 3 and the first blade 21 are both spaced apart in the axial direction and the circumferential direction of the tool holder 1.

[0158] It can be understood that both the second blade 3 and the first blade 21 provided on the outer peripheral wall of the main body 22 rotate in the first direction, and the cutter group 2 has a first installation state and a second installation state. The feeding end of the first blade 21 in the first installation state is the discharging end of the first blade 21 in the second installation state, and the feeding end of the second blade 3 in the first installation state is the discharging end of the second blade 3 in the second installation state. Moreover, the feeding end of the second blade 3 provided on the outer peripheral wall of the tool holder 1 is always fixed. Thus, through the fixing treatment effect of the second blade 3 on the tool holder 1 and the treatment effects of the cutter group 2 in the first installation state and the second installation state, different treatment effects of the blade assembly 100 on the material are achieved. At the same time, by arranging a plurality of second blades 3 and first blades 21 at intervals in both the axial direction and the circumferential direction of the tool holder 1, the cutting and stirring effects of the first blade 21 and the second blade 3 on the material are improved, thereby enhancing the treatment effect of the blade assembly 100 on the material.

[0159] Furthermore, the feeding end of the second blade 3 provided on the outer peripheral wall of the tool holder 1 is a sharp edge or a blunt edge, and the other end has no edge. Thus, when the feeding end of the second blade 3 is a sharp edge, the second blade 3 fully cuts the material when the tool holder 1 rotates in the first direction; when the feeding end of the second blade 3 is a blunt edge, the second blade 3 stirs and pats the material and transports the material downward when the tool holder 1 rotates in the first direction. At the same time, since the discharging end of the second blade 3 has no edge, the processing of the second blade 3 is reduced, and the cost is lowered.

[0160] In some embodiments of the present invention, as Figure 33 shown, the second blades 3 provided on the outer peripheral wall of the main body 22 are all located on the same side of the first blade 21 in the axial direction of the main body 22. Thus, after multiple second blades 3 all process the material, the first blade 21 processes the material, or, after the first blade 21 processes the material, multiple second blades 3 sequentially process the material, further ensuring the treatment effect of the blade assembly 100 on the material.

[0161] Further, when the second blade 3 is provided on the outer peripheral wall of the main body portion 22, the first blade 21 includes a main body portion 219 and a bent portion 220. The main body portion 219 extends in the radial direction of the main body portion 22 and one end thereof is connected to the outer peripheral wall of the main body portion 22. The bent portion 220 extends in the axial direction of the main body portion 22 and one end thereof is connected to the end of the main body portion 219 far from the main body portion 22. The end of the bent portion 220 far from the main body portion 219 extends toward the second blade 3. Both ends of the second blade 3 in the circumferential direction of the tool holder 1 are arcs protruding in the same direction in the circumferential direction of the main body portion 22. Thus, in the first installation state, a plurality of second blades 3 are located above the first blade 21. When the tool holder 1 rotates in the first direction, after the material is cut by the plurality of second blades 3, the material clamped between the material and the side wall of the cup body 200 is extruded by the first blade 21, reducing the accumulation of the material on the side wall; in the second installation state, a plurality of second blades 3 are located below the first blade 21. When the tool holder 1 rotates in the first direction, first, the material is stirred, thrown, and transported downward by the first blade 21 so that the plurality of second blades 3 can sufficiently cut the material.

[0162] The food processor 1000 according to an embodiment of the present invention will be described below.

[0163] The food processor 1000 according to an embodiment of the present invention, as Figure 1 shown, includes a cup body 200, a blade assembly 100, a cover plate 300, and a main body. Among them, one end of the cup body 200 is open, the blade assembly 100 is located inside the cup body 200, the cover plate 300 is disposed at the open port 201 of the cup body 200, the cover plate 300 has a through hole 301 for the tool holder 1 to extend out, the main machine 400 is disposed on the cover plate 300 or the cup body 200, and the main machine 400 includes a driving mechanism 401. The output shaft of the driving mechanism 401 is connected to the tool holder 1 extending out of the cup body 200.

[0164] Thus, when the food processor 1000 needs to cut and stir the material, the material is placed in the stirring space of the cup body 200 from the open port 201 of the cup body 200. The cover plate 300 is disposed at the open port 201 of the cup body 200 so that the cover plate 300 and the stirring space cooperate to limit a closed stirring cavity. The main body portion 219 is detachably sleeved on the tool holder 1 to realize the switching between the first installation state and the second installation state of the cutter group 2, so that the blade assembly 100 can process the food in the stirring space in both the first installation state and the second installation state only through one cutter group 2, thereby reducing the production cost of the cutter group 2 assembly, facilitating the user's storage, optimizing the user's use experience, further enhancing the practicability and reliability of the food processor 1000, and improving the product competitiveness.

[0165] According to the food processor 1000 of the embodiment of the present invention, a blade assembly 100 is provided. One end of the cup body 200 is open. The blade assembly 100 is located inside the cup body 200. The cover plate 300 is covered at the open mouth 201 of the cup body 200. The cover plate 300 has a through hole 301 for the cutter base 1 to extend out. The main body 400 is arranged on the cover plate 300 or the cup body 200. The main body 400 includes a driving mechanism 401. The output shaft of the driving mechanism 401 is connected to the cutter base 1 extending out of the cup body 200. By detachably sleeving the main body part 219 on the cutter base 1, the cutter group 2 is realized to switch between the first installation state and the second installation state, so that the blade assembly 100 can process the food located in the stirring space in both the first installation state and the second installation state only through one cutter group 2, thereby reducing the production cost of the cutter group 2 assembly, being convenient for users to store, optimizing the user experience, further strengthening the practicability and reliability of the food processor 1000, and enhancing the product competitiveness.
