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 situations.

[0046] Reference will be made below to Figure 1 Describe the food processor 1000 according to an embodiment of the present invention.

[0047] 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 covered at the open end 201 of the cup body 200, the cover plate 300 has a through hole 301 for the blade seat 1 of the blade assembly 100 to extend out, the main body 400 is provided on the cover plate 300 or the cup body 200, the main body 400 includes a driving mechanism 401, and the output shaft of the driving mechanism 401 is connected to the blade seat 1 of the blade assembly 100 extending out of the cup body 200.

[0048] 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 covered 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.

[0049] 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 pulverizer. Of course, the food processor 1000 of this embodiment can also be applied to industrial production, for example, applied to the processing and production of materials on a production line. The materials are not limited to food ingredients, but can also be other materials that need to be processed by cutting.

[0050] Next, the blade assembly 100 according to an embodiment of the present invention will be described with reference to the accompanying drawings.

[0051] As Figures 2 - 7 shown, the blade assembly 100 according to an embodiment of the present invention includes a tool holder 1, a first blade 2, and a second blade 3. Among them, the first blade 2 and the second blade 3 are respectively provided on the outer peripheral wall of the tool holder 1, and the shapes of the first blade 2 and the second blade 3 are different. At least one of the first blade 2 and the second blade 3 has a first cutting edge 21 and a second cutting edge 22 at both ends in the circumferential direction of the tool holder 1, and the edge thickness of the first cutting edge 21 is greater than the edge thickness of the second cutting edge 22.

[0052] It can be understood that, due to the different shapes of the first blade 2 and the second blade 3, the cutting effects of the first blade 2 and the second blade 3 on the material are different. At the same time, since the edge thickness of the first cutting edge 21 of at least one of the first blade 2 and the second blade 3 is greater than the edge thickness of the second cutting edge 22, when the first cutting edge 21 is located at the material receiving end, it realizes the patting and stirring and tumbling of the material, and when the second cutting edge 22 is located at the material receiving end, it realizes better cutting of the material and improves the uniformity of material pulverization. Thus, the cutting effects of the first cutting edge 21 and the second cutting edge 22 on the material are different. Furthermore, when the driving mechanism 401 drives the tool holder 1 in two opposite rotation directions, the first cutting edge 21 or the second cutting edge 22 is respectively located at the material receiving end of the blade having the first cutting edge 21 and the second cutting edge 22, thereby realizing the non-uniform cutting and stirring effects of the food processor 1000 on the material.

[0053] Specifically, when the food processor 1000 applying the blade assembly 100 is operating, the drive mechanism 401 drives the tool holder 1 to rotate in two opposite rotational directions in the first direction and the second direction. When the tool holder 1 rotates in the first direction, the material feeding end is the first cutting edge 21 of the corresponding first blade 2 or the second blade 3 having the first cutting edge 21 and the second cutting edge 22, realizing the first processing performance of the food processor 1000 on the material; when the tool holder 1 rotates in the first direction, the material feeding end is the second cutting edge 22 of the corresponding first blade 2 or the second blade 3 having the first cutting edge 21 and the second cutting edge 22, realizing the second processing performance of the food processor 1000 on the material; when the tool holder 1 rotates in a combined manner in the first direction and the second direction, the material feeding end switches between the first cutting edge 21 and the second cutting edge 22 of the corresponding first blade 2 or the second blade 3 having the first cutting edge 21 and the second cutting edge 22, realizing the third processing performance of the food processor 1000 on the material.

[0054] Compared with the prior art in which different processing performances of the food processor 1000 are achieved by respectively sleeving multiple detachable cutter groups on the tool holder 1, the blade assembly 100 of the present invention can achieve different processing performances of the food processor 1000 with only one cutter group, thereby reducing production costs, facilitating user storage, optimizing the user experience, and further enhancing the practicability and reliability of the product, and improving the product competitiveness.

[0055] Meanwhile, the first blade 2 and the second blade 3 are spaced apart in the circumferential direction of the tool holder 1, thereby improving the cutting and stirring effect of the first blade 2 and the second blade 3 on the material, improving the processing effect of the blade assembly 100 on the material, and further improving the product competitiveness.

[0056] In addition, at least one of the first blade 2 and the second blade 3 has a first cutting edge 21 and a second cutting edge 22 at both ends in the circumferential direction of the tool holder 1, further realizing the non-cutting and stirring effect of the blade assembly 100 on the material. For example, only the first blade 2 has a first cutting edge 21 and a second cutting edge 22 at both ends in the circumferential direction of the tool holder 1; or, only the second blade 3 has a first cutting edge 21 and a second cutting edge 22 at both ends in the circumferential direction of the tool holder 1; or, both the first blade 2 and the second blade 3 have a first cutting edge 21 and a second cutting edge 22 at both ends in the circumferential direction of the tool holder 1; or, the first blade 2 has a first cutting edge 21 and a second cutting edge 22 at both ends in the circumferential direction of the tool holder 1, and the second blade 3 has a first cutting edge 21 at one end in the circumferential direction of the tool holder 1; or, the first blade 2 has a first cutting edge 21 and a second cutting edge 22 at both ends in the circumferential direction of the tool holder 1, the second blade 3 has a second cutting edge 22 at one end in the circumferential direction of the tool holder 1, the second blade 3 has a first cutting edge 21 and a second cutting edge 22 at both ends in the circumferential direction of the tool holder 1, and the first blade 2 has a first cutting edge 21 at one end in the circumferential direction of the tool holder 1; or, the second blade 3 has a first cutting edge 21 and a second cutting edge 22 at both ends in the circumferential direction of the tool holder 1, and the first blade 2 has a second cutting edge 22 at one end in the circumferential direction of the tool holder 1.

[0057] For the blade assembly 100 according to an embodiment of the present invention, the first blade 2 and the second blade 3 are respectively arranged on the outer peripheral wall of the tool holder 1. Since the shapes of the first blade 2 and the second blade 3 are different, the cutting effects of the first blade 2 and the second blade 3 on the material are different. And at least one of the first blade 2 and the second blade 3 has a first cutting edge 21 and a second cutting edge 22 at both ends in the circumferential direction of the tool holder 1, and the edge thickness of the first cutting edge 21 is greater than the edge thickness of the second cutting edge 22, so that the cutting effects of the first cutting edge 21 and the second cutting edge 22 on the material are different. Thus, different cutting and stirring effects on the material are realized by the first blade 2 and the second blade 3 on one tool group, the production cost is reduced, and it is convenient for the user to store, optimizing the user experience, and further enhancing the practicability and reliability of the product and improving the product competitiveness.

[0058] In some embodiments of the present invention, such as Figures 4 - 7As shown, the edge thickness of the first cutting edge 21 is T1, the edge thickness of the second cutting edge 22 is T2, and the thickness of the corresponding first blade 2 or second blade 3 having the first cutting edge 21 and the second cutting edge 22 is H, wherein 0.15 mm ≤ T1 < H1, 0 < T2 < 0.15 mm. It can be understood that the edge thickness of the first blade 21 can be any value between 0.15 or 0.15 mm and the thickness of the first blade 2, and the edge thickness of the second blade 22 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. Therefore, through such an arrangement, it is ensured that the edge thickness of the first blade 21 is greater than the edge thickness of the second blade 22. At the same time, the cutting effect of the first blade 21 on the material is ensured by the edge thickness of the first blade 21 being less than the thickness of the corresponding first blade 2 or second blade 3 having the first blade 21 and the second blade 22.

[0059] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, the first blade 2 and the second blade 3 are spaced apart in the axial direction of the blade holder 1. Thus, such an arrangement further improves the cutting and stirring effects of the first blade 2 and the second blade 3 on the material, and improves the processing effect of the blade assembly 100 on the material.

[0060] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, the second blade 3 includes a main body portion 31 and a bending portion 32, the main body portion 31 extends along the radial direction of the blade seat 1 and one end is connected to the outer peripheral wall of the blade seat 1, one end of the bending portion 32 is connected to the end of the main body portion 31 away from the blade seat 1, and the other end extends toward the first blade 2.

[0061] Thus, in the process of cutting and stirring the material by the second blade 3, while the material is cut and stirred by the main body 31, the material is further cut and stirred by the bending portion 32, thereby avoiding material accumulation as much as possible, and better beating the material, and ensuring that the second blade 3 and the first blade 2 cut the material without dead angles as much as possible, thereby improving the cutting and stirring effect of the blade assembly 100 on the material. In addition, the bending portion 32 extends away from the main body 31 toward the first blade 2, so that the material between the first blade 2 and the second blade 3 is in a vortex state, thereby achieving cutting and crushing of the material without dead angles, and further improving the processing effect of the blade assembly 100 on the material.

[0062] In some embodiments of the present invention, Figure 2 and Figure 3As shown, there are multiple first blades 2 and one second blade 3. The multiple first blades 2 are spaced apart both in the axial direction and the circumferential direction of the tool holder 1, and the multiple first blades 2 are located on the same side of the second blade 3. Thus, through the cutting and stirring of the material by the multiple first blades 2, the cutting and stirring effect of the second blade 3 on the material, and the stirring and throwing effect of the bending part 32 on the material, the processing effect of the blade assembly 100 on the material is improved. At the same time, during the process of the blade assembly 100 cutting and stirring the material, since the multiple first blades 2 are located on the same side of the second blade 3, after the multiple first blades 2 all cut and stir the material, they are then cut, stirred, and thrown by the second blade 3, or, after the second blade 3 cuts, stirs, and throws the material, they are then cut and stirred by the multiple first blades 2, further ensuring the processing effect of the blade assembly 100 on the material.

[0063] When the blade assembly 100 is applied to the food processor 1000, the blade assembly 100 is located inside the cup body 200. The cup body 200 has an open mouth 201. The multiple first blades 2 are all located on the side of the second blade 3 close to the open mouth 201. One end of the bending part 32 away from the body part 31 extends towards the open mouth 201. Thus, through such a setting, when the tool holder 1 rotates in the first direction or the second direction, the throwing and stirring effect of the bending part 32 on the material is ensured, and the processing effect of the food processor 1000 on the material is improved.

[0064] In some embodiments of the present invention, such as Figure 2 and Figure 3 As shown, both opposite edges of the first blade 2 along the circumferential direction of the tool holder 1 are arcs protruding in the same direction along the circumferential direction of the tool holder 1. Thus, through such a setting, when the first blade 2 rotates, it can better form a convergent circular flow, 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 first blade 2 on the material, and further effectively reducing the power of the motor of the drive mechanism 401 of the food processor 1000, reducing costs, and enhancing product competitiveness.

[0065] In some embodiments of the present invention, such as Figures 4 - 7 As shown, both ends of the first blade 2 and the second blade 3 along the circumferential direction of the tool holder 1 respectively have a first cutting edge 21 and a second cutting edge 22. The tool holder 1 can rotate in the first direction and the second direction, and the first direction and the second direction are opposite. Thus, when the tool holder 1 rotates in different directions, the first cutting edge 21 and the second cutting edge 22 of the first blade 2 and the second blade 3 are respectively located at the material receiving end, thereby realizing the processing effect of the blade assembly 100 on the material.

[0066] Furthermore, as shown in Figure 2 and Figure 3As shown, the second blade 3 includes a main body 31 and a bent portion 32. The main body 31 extends along the radial direction of the blade holder 1 and one end is connected to the outer peripheral wall of the blade holder 1. One end of the bent portion 32 is connected to the end of the main body 31 away from the blade holder 1, and the other end extends toward the first blade 2. Therefore, while the main body 31 cuts and stirs the material, the bent portion 32 further cuts and stirs the material, thereby avoiding material accumulation as much as possible, and better beating the material, and ensuring that the second blade 3 and the first blade 2 cut the material without dead angles, thereby improving the cutting and stirring effect of the blade assembly 100 on the material. In addition, by extending the end of the bent portion 32 away from the main body 31 toward the first blade 2, the material between the first blade 2 and the second blade 3 is in a vortex state, thereby achieving cutting and crushing of the material without dead angles, and further improving the processing effect of the blade assembly 100 on the material.

[0067] In some embodiments of the present invention, Figure 8 As shown, when the knife seat 1 rotates along the first direction, the first blade 21 of the first blade 2 and the first blade 21 of the second blade 3 are both located at the material-facing end of the first blade 2 or the second blade 3. Thus, through such a setting, when the knife seat 1 rotates along the first direction, the first blade 21 of the first blade 2 and the first blade 3 are both located at the material-facing end of the first blade 2 or the second blade 3, and the material-facing ends of the first blade 2 and the second blade 3 are both the first blade 21 with a relatively thick cutting edge, thereby achieving full beating and stirring of the material, thereby achieving the first material processing effect of the blade assembly 100; when the knife seat 1 rotates along the second direction, the second blade 22 of the first blade 2 and the second blade 3 are both located at the material-facing end of the first blade 2 or the second blade 3, and the material-facing ends of the first blade 2 and the second blade 3 are both the second blade 22 with a relatively thin cutting edge, thereby achieving full cutting of the material, thereby improving the uniformity of material crushing, thereby achieving the second material processing effect of the blade assembly 100.

[0068] Meanwhile, during the reciprocating rotation of the tool holder 1 in the first direction and the second direction, the combined processing effect of the blade assembly 100 on the material is realized, so as to achieve different cutting and stirring effects on the material. For example, first, the tool holder 1 rotates in the first direction, so that the first blade 2 and the second blade 3 first beat and stir the material, which is beneficial to the efficiency and uniformity of the subsequent stirring of the material. Then, when the tool holder 1 rotates in the second direction, the first blade 2 and the second blade 3 cut the already stirred material into pieces, so as to perform high-efficiency cutting and improve the uniformity of material crushing; or, first, the tool holder 1 rotates in the second direction, so that the first blade 2 or the second blade 3 realizes the crushing of the material, and then the tool holder 1 rotates in the second direction, so that the first blade 2 or the second blade 3 beats, stirs and tumbles the already crushed material, further realizing the uniform stirring of the crushed material.

[0069] In some embodiments of the present invention, as Figure 9 shown, when the tool holder 1 rotates in the first direction, the first cutting edge 21 of the first blade 2 and the second cutting edge 22 of the second blade 3 are both located at the material receiving end of the first blade 2 or the second blade 3. Thus, through such a setting, when the tool holder 1 rotates in the first direction, the first cutting edge 21 of the first blade 2 and the second cutting edge 22 of the second blade 3 are both located at the material receiving end of the first blade 2 or the second blade 3, and the material receiving end of the first blade 2 is the first cutting edge 21 with a relatively thick edge thickness, and the material receiving end of the second blade 3 is the second cutting edge 22 with a relatively thin edge thickness. Therefore, the first blade 2 realizes full beating and stirring of the material, and the second blade 3 realizes full cutting of the material, so as to improve the uniformity of material crushing, and further realize the first processing effect of the material of the blade assembly 100. At the same time, when the blade assembly 100 is applied to the food processor 1000, the blade assembly 100 is located in the cup body 200. The cup body 200 has an open mouth 201, and when the first blade 2 is located on the side of the second blade 3 close to the open mouth 201, by rotating the tool holder 1 in the first direction, the first blade 2 realizes beating, stirring, tumbling and downward transporting of the material, so that the second blade 3 can cut the material more fully, reducing the accumulation of the material at the bottom wall of the cup body 200.

[0070] When the tool holder 1 rotates in the second direction, the second cutting edge 22 of the first blade 2 and the first cutting edge 21 of the second blade 3 are both located at the material receiving end of the first blade 2 or the second blade 3. The material receiving end of the second blade 3 serves as the cutting edge with a relatively thick thickness for the first cutting edge 21, and the material receiving end of the first blade 2 serves as the cutting edge with a relatively thin thickness for the second cutting edge 22. Thus, the second blade 32 can fully beat and stir the material, and the first blade 2 can fully cut the material, so as to improve the uniformity of material crushing, and further achieve the second processing effect of the material by the blade assembly 100. At the same time, when the blade assembly 100 is applied to the food processor 1000, the blade assembly 100 is located in the cup body 200. The cup body 200 has an open mouth 201. When the first blade 2 is located on the side of the second blade 3 close to the open mouth 201, by rotating the tool holder 1 in the second direction, the second blade 3 can beat, stir, tumble the material and send the material upward, so that the first blade 2 can further cut the material, improving the uniformity of cutting.

[0071] In addition, during the reciprocating rotation of the tool holder 1 in the first direction and the second direction, the combined processing effect of the blade assembly 100 on the material is realized, so as to achieve different cutting and stirring effects on the material. For example, when the blade assembly 100 is applied to the food processor 1000, the blade assembly 100 is located in the cup body 200. The cup body 200 has an open mouth 201. When the first blade 2 is located on the side of the second blade 3 close to the open mouth 201, first, by rotating the tool holder 1 in the second direction, the second blade 3 can beat, stir, tumble the material and send the material upward, and the first blade 2 can further cut the material, improving the uniformity of cutting. Then, when the tool holder 1 rotates in the first direction, the first blade 2 can beat, stir, tumble the already whipped material and send the material downward, so that the second blade 3 can cut the material more fully, reducing the accumulation of the material at the bottom wall of the cup body 200, and further better realizing the cutting of the material.

[0072] In some embodiments of the present invention, the two ends of the first blade 2 in the circumferential direction of the tool holder 1 respectively have a first cutting edge 21 and a second cutting edge 22. One end of the second blade 3 in the circumferential direction of the tool holder 1 has a first cutting edge 21. The tool holder 1 can rotate in the first direction and the second direction, and the first direction and the second direction are opposite. It can be understood that one end of the second blade 3 in the circumferential direction of the tool holder 1 has a first cutting edge 21, and the other end is without a cutting edge. When the end without a cutting edge is the material receiving end of the second blade 3, the function of beating, stirring and tumbling the material is realized through the end without a cutting edge, so that the material is evenly mixed. Thus, by rotating the tool holder 1 in different directions, the first cutting edge 21 and the second cutting edge 22 of the first blade 2 and the first cutting edge and the end without a cutting edge of the second blade 3 are respectively located at the material receiving end, so as to realize the processing effect of the blade assembly 100 on the material.

[0073] Furthermore, asFigure 2 and Figure 3 As shown, the second blade 3 includes a body portion 31 and a bending portion 32, the body portion 31 extends in the radial direction of the blade holder 1 and one end is connected to the outer peripheral wall of the blade holder 1, one end of the bending portion 32 is connected to the end of the body portion 31 away from the blade holder 1, and the other end extends toward the first blade 2. Therefore, while the body portion 31 cuts and stirs the material, the bending portion 32 further cuts and stirs the material, thereby avoiding material accumulation as much as possible, and the bending portion 32 extends toward the first blade 2 at the end away from the body portion 31, so that the material between the first blade 2 and the second blade 3 is in a vortex state, thereby achieving cutting and crushing of the material without dead angles.

[0074] In some embodiments of the present invention, when the knife seat 1 rotates along the first direction, the first blade 21 of the first blade 2 and the first blade 21 of the second blade 3 are both located at the material-facing end of the first blade 2 or the second blade 3. Thus, through such a setting, when the knife seat 1 rotates along the first direction, the material-facing ends of the first blade 2 and the second blade 3 are both the first blade 21 with relatively thick cutting edges, so that the material can be fully beaten and stirred, thereby achieving the first material processing effect of the blade assembly 100; when the knife seat 1 rotates along the second direction, the second blade 22 of the first blade 2 is located at the material-facing end of the first blade 2, and the bladeless end of the second blade 3 is located at the material-facing end of the second blade 3, and the second blade 3 has the effect of beating, stirring and tumbling, and the second blade 22 of the first blade 2 can achieve better cutting, improve the uniformity of material crushing, and thereby achieve the second material processing effect of the blade assembly 100.

[0075] At the same time, during the process of the knife seat 1 reciprocating along the first direction and the second direction, the blade assembly 100 realizes the combined processing effect of the material, thereby realizing different cutting and stirring effects on the material. For example, the knife seat 1 is first rotated along the first direction so that the first blade 2 and the second blade 3 first beat and stir the material, which is beneficial to the efficiency and uniformity of the subsequent whipping of the material. When the knife seat 1 is rotated along the second direction, the whipped material is beaten and stirred and tumbled by the second blade 3, and the first blade 2 can cut better, thereby improving the uniformity of material crushing; or, the knife seat 1 is first rotated along the second direction so that the first blade 2 and the second blade 3 beat and stir and tumble the crushed material, and then the knife seat 1 is rotated along the first direction so that the first blade 2 and the second blade 3 beat and stir and tumble the crushed material, further realizing the uniform whipping of the crushed material.

[0076] In some embodiments of the present invention, when the tool holder 1 rotates in the first direction, the second cutting edge 22 of the first blade 2 and the first cutting edge 21 of the second blade 3 are both located at the material receiving end of the first blade 2 or the second blade 3. Thus, through such an arrangement, when the tool holder 1 rotates in the first direction, and due to the first cutting edge 21 of the second blade 3 having the functions of patting and stirring and tumbling, the second cutting edge 22 of the first blade 2 can perform better cutting, improving the uniformity of material crushing, and further achieving the first processing effect of the material by the blade assembly 100; when the tool holder 1 rotates in the second direction, the first cutting edge 21 of the first blade 2 is located at the material receiving end of the first blade 2, and the non-cutting edge of the second blade 3 is located at the material receiving end of the second blade 3. Through the non-cutting edge of the second blade and the first cutting edge 21 of the first blade 2, sufficient patting and stirring of the material are achieved, and further the second processing effect of the material by the blade assembly 100 is realized.

[0077] Meanwhile, during the reciprocating rotation of the tool holder 1 in the first direction and the second direction, the combined processing effect of the blade assembly 100 on the material is achieved, thereby realizing different cutting and stirring effects on the material. For example, first, the tool holder 1 rotates in the first direction to enable the first blade 2 to crush the material and the second blade 3 to stir the material, and then the tool holder 1 rotates in the second direction to enable the first blade 2 and the second blade 3 to pat and stir and tumble the already crushed material, further realizing the uniform whipping of the crushed material; first, the tool holder 1 rotates in the second direction to enable the first blade 2 and the second blade 3 to pat and stir the material, which is beneficial to the efficiency and uniformity of the subsequent whipping of the material, and then the tool holder 1 rotates in the first direction to enable the first blade 2 to crush the material and the second blade 3 to stir the material, further realizing the uniform whipping of the crushed material.

[0078] In some embodiments of the present invention, the two ends of the first blade 2 in the circumferential direction of the tool holder 1 respectively have a first cutting edge 21 and a second cutting edge 22, one end of the second blade 3 in the circumferential direction of the tool holder 1 has a second cutting edge 22, the tool holder 1 is rotatable in the first direction and the second direction, and the first direction and the second direction are opposite. It can be understood that one end of the second blade 3 in the circumferential direction of the tool holder 1 has a first cutting edge 21, and the other end is a non-cutting edge. When the non-cutting edge is the material receiving end of the second blade 3, the non-cutting edge realizes the functions of patting and stirring and tumbling the material to make the material mix evenly. Thus, by rotating the tool holder 1 in different directions, it is realized that the first cutting edge 21 and the second cutting edge 22 of the first blade 2 and the first cutting edge and the non-cutting edge of the second blade 3 are respectively located at the material receiving end, thereby realizing the processing effect of the blade assembly 100 on the material.

[0079] Further, as Figure 2 and Figure 3As shown, the second blade 3 includes a body portion 31 and a bending portion 32, the body portion 31 extends in the radial direction of the blade holder 1 and one end is connected to the outer peripheral wall of the blade holder 1, one end of the bending portion 32 is connected to the end of the body portion 31 away from the blade holder 1, and the other end extends toward the first blade 2. Therefore, while the body portion 31 cuts and stirs the material, the bending portion 32 further cuts and stirs the material, thereby avoiding material accumulation as much as possible, and the bending portion 32 extends toward the first blade 2 at the end away from the body portion 31, so that the material between the first blade 2 and the second blade 3 is in a vortex state, thereby achieving cutting and crushing of the material without dead angles.

[0080] In some embodiments of the present invention, when the knife seat 1 rotates along the first direction, the first blade 21 of the first blade 2 and the second blade 3 of the second blade 3 are both located at the material-facing end of the first blade 2 or the second blade 3. Thus, through such a setting, when the knife seat 1 rotates along the first direction, the first blade 21 has the effect of beating and stirring and tumbling, and the second blade 22 of the second blade 3 can achieve better cutting and improve the uniformity of material crushing, thereby achieving the first material processing effect of the blade assembly 100; when the knife seat 1 rotates along the second direction, the second blade 22 of the first blade 2 is located at the material-facing end of the first blade 2, and the bladeless end of the second blade 3 is located at the material-facing end of the second blade 3, and the second blade 22 of the first blade 2 can achieve better cutting and improve the uniformity of material crushing, and the bladeless end of the second blade and the first blade 21 of the first blade 2 can achieve sufficient beating and stirring of the material, thereby achieving the second material processing effect of the blade assembly 100.

[0081] Meanwhile, during the reciprocating rotation of the tool holder 1 in the first direction and the second direction, the combined processing effect of the blade assembly 100 on the material is realized, so as to achieve different cutting and stirring effects on the material. For example, when the blade assembly 100 is applied to the food processor 1000, the blade assembly 100 is located in the cup body 200. The cup body 200 has an open mouth 201. When the first blade 2 is located on the side of the second blade 3 close to the open mouth 201, first, the tool holder 1 rotates in the first direction. The first cutting edge 21 of the first blade 2 pats, stirs, tumbles and transports the material downward, and the second cutting edge 22 of the second blade 3 cuts and crushes the material, so that the material can be better cut, and the accumulation of the material at the bottom wall is reduced. Then, the tool holder 1 rotates in the second direction again. The non-cutting edge of the second blade 22 pats, stirs, tumbles and transports the already crushed material upward, and the second cutting edge 22 of the first blade 2 cuts and crushes the material, further improving the uniformity of cutting; or, first, the tool holder 1 rotates in the second direction. The non-cutting edge of the second blade 22 pats, stirs, tumbles and transports the material upward, and the second cutting edge 22 of the first blade 2 cuts and crushes the material. Then, the tool holder 1 rotates in the first direction again. The first cutting edge 21 of the first blade 2 pats, stirs, tumbles and transports the already crushed material downward, and the second cutting edge 22 of the second blade 3 cuts and crushes the material, so that the material can be better cut, and the accumulation of the material at the bottom wall is reduced, further improving the uniformity of cutting.

[0082] In some embodiments of the present invention, when the tool holder 1 rotates in the first direction, the second cutting edge 22 of the first blade 2 and the second cutting edge 22 of the second blade 3 are both located at the material receiving end of the first blade 2 or the second blade 3. Thus, through such a setting, when the tool holder 1 rotates in the first direction, the second cutting edge 22 of the first blade 2 and the second cutting edge 22 of the second blade 3 can cut the material better, improve the uniformity of material crushing, and further realize the first processing effect of the material of the blade assembly 100; when the tool holder 1 rotates in the second direction, the first cutting edge 21 of the first blade 2 is located at the material receiving end of the first blade 2, and the non-cutting edge of the second blade 3 is located at the material receiving end of the second blade 3. The first cutting edge 21 of the first blade 2 and the non-cutting edge of the second blade 3 can fully pat and stir the material, and further realize the second processing effect of the material of the blade assembly 100.

[0083] Meanwhile, during the reciprocating rotation of the tool holder 1 in the first direction and the second direction, the combined processing effect of the blade assembly 100 on the material is realized, so as to achieve different cutting and stirring effects on the material. For example, when the blade assembly 100 is applied to the food processor 1000, the blade assembly 100 is located in the cup body 200. The cup body 200 has an open mouth 201, and when the first blade 2 is on the side of the second blade 3 close to the open mouth 201, first, the tool holder 1 rotates in the first direction, and the second cutting edges 22 of the first blade 2 and the second cutting edges 22 of the second blade 3 fully cut the material. Then, the tool holder 1 rotates in the second direction again to further beat and mix the already crushed material to make the material evenly mixed, which is beneficial to subsequent whipping; or, first, the tool holder 1 rotates in the second direction, and the first cutting edge 21 of the first blade 2 and the non-cutting edge of the second blade 3 are used to beat and stir the material, which is beneficial to the efficiency and uniformity of subsequent whipping of the material. Then, the tool holder 1 rotates in the first direction again, and the already evenly stirred material is fully cut by the second cutting edges 22 of the first blade 2 and the second cutting edges 22 of the second blade 3 to further cut the material with high efficiency and improve the uniformity of material crushing.

[0084] The food processor 1000 according to an embodiment of the present invention will be described below.

[0085] 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 400. Among them, one end of the cup body 200 is open, the blade assembly 100 is located in 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 tool holder 1 to extend out, the main body 400 is arranged on the cover plate 300 or the cup body 200, and the main body 400 includes a driving mechanism 401, and the output shaft of the driving mechanism 401 is connected to the tool holder 1 extending out of the cup body 200.

[0086] 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 mouth 201 of the cup body 200. The cover plate 300 is covered 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. Due to the different shapes of the first blade 2 and the second blade 3, the cutting effects of the first blade 2 and the second blade 3 on the material are different. At the same time, the edge thickness of the first cutting edge 21 of at least one of the first blade 2 and the second blade 3 is greater than that of the second cutting edge 22, so that the cutting effects of the first cutting edge 21 and the second cutting edge 22 on the material are different, so that when the driving mechanism 401 drives the tool holder 1 in two opposite rotation directions, the first cutting edge 21 or the second cutting edge 22 is located at the material receiving end of the first blade 2 respectively. Thus, the combined use of the first blade 2 and the second blade 3 realizes the non-uniform cutting and stirring effect on the material.

[0087] According to the food processor 1000 of the embodiment of the present invention, a blade assembly 100 is provided. The blade assembly 100 is located in 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 tool holder 1 to extend out. The main machine 400 is arranged on the cover plate 300 or the cup body 200. 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. Due to the different shapes of the first blade 2 and the second blade 3, the cutting effects of the first blade 2 and the second blade 3 on the material are different. And at least one of the first blade 2 and the second blade 3 has a first cutting edge 21 and a second cutting edge 22 at both ends along the circumferential direction of the tool holder 1. The edge thickness of the first cutting edge 21 is greater than that of the second cutting edge 22, so that the cutting effects of the first cutting edge 21 and the second cutting edge 22 on the material are different. Thus, different cutting and stirring effects on the material are realized by the first blade 2 and the second blade 3 on one tool group, reducing the production cost, facilitating the user to store, optimizing the user experience, and further enhancing the practicability and reliability of the product and improving the product competitiveness.
