[0045] In order to make the objectives, technical solutions and advantages of the present application clearer, the following part will further describe the embodiments of the present application in detail in conjunction with the accompanying drawings.

[0046] When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are only examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances. In addition, in the description of the present application, unless otherwise specified, "multiple" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the objects associated before and after are in an "or" relationship.

[0048] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in this specification are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0049] An embodiment of the present application proposes a food processor, which is a machine that can process fruits, vegetables and other foods into paste-like ingredients. For example, the food processor can be a juicer, a wall breaking machine, a juicer, a soy milk machine, or any other device used for processing food materials.

[0050] In some embodiments, the food processor includes a base assembly and a cup assembly, the cup assembly is mounted on the base assembly, and defines a food processing chamber for holding food. Specifically, the present application also proposes a cup assembly, which includes a cup body, a cup seat and a knife assembly 1. The cup seat is used to provide a connection basis between the cup assembly and the base assembly, and the cup body is mounted on the cup seat to define the above-mentioned food processing chamber with the cup seat. Commonly, the cup body is roughly cylindrically arranged to accommodate more food and facilitate the cutting operation of the knife assembly 1. Of course, the shape of the cup body can be adaptively adjusted according to actual needs, and the embodiments of the present application are not limited here. The knife assembly 1 is connected to the cup seat and extends into the cup body, and is located in the food processing chamber. It can be understood that a drive member for driving the knife assembly 1 to operate is provided in the base assembly, and optionally, the drive member is a motor, and the knife assembly 1 is connected to the output end of the drive member to cut and crush the food in the food processing chamber under the drive of the drive member.

[0051] It should be noted that, in some other embodiments, the food processor may include a base assembly and a knife assembly 1, wherein the base assembly itself forms a food processing chamber, and the knife assembly 1 is connected above the base assembly and extends into the food processing chamber from top to bottom.

[0052] In order to improve the crushing effect and make the crushed food more delicate, the food processor in the related art adopts the method of increasing the output power of the driving part. However, the above method undoubtedly puts higher requirements on the specifications of the driving part, thereby increasing the product cost and having poor economic benefits. In addition, the high-power output driving part may also bring greater noise and vibration, reduce the operating quality of the food processor, and poor user experience.

[0053] In view of this, please refer to Figure 1 and Figure 2 The present application also provides a knife assembly 1. The knife assembly 1 is explained below by taking a food processor placed horizontally and having a height direction perpendicular to the horizontal plane as an example.

[0054] like Figure 1 As shown, in some embodiments, the knife assembly 1 includes a knife shaft 10 and a knife 20 . The knife shaft 10 is used to connect with a cup base or a machine base assembly, and the knife 20 is disposed on the knife shaft 10 .

[0055] The knife shaft 10 is arranged in a rod-like shape and extends roughly along the height direction of the food processor. Depending on the actual situation, the extension direction of the knife shaft 10 can be parallel to the height direction or arranged at an angle, which is not limited here. Along the height direction, the knife shaft 10 has a first end 11 and a second end 12 arranged opposite to each other, wherein the first end 11 is used to connect to the output end of the driving member, and the second end 12 is a free end. Exemplarily, the first end 11 is the lower end of the knife shaft 10, and the second end 12 is the upper end of the knife shaft 10. The knife shaft 10 can rotate around its own extension direction under the drive of the driving member, so that the tool 20 arranged on the knife shaft 10 rotates accordingly, that is, the extension direction of the knife shaft 10 is the axial direction of the knife shaft 10.

[0056] At least three groups of knives 20 may be arranged on the knife shaft 10 along the axial direction of the knife shaft 10, namely, a first knife 21, a second knife 22 and a third knife 23, and the first knife 21, the second knife 22 and the third knife 23 are arranged in sequence from top to bottom along the height direction. It can be understood that the roots of two adjacent groups of knives 20 are arranged at intervals, on the one hand, to expand the crushing space of the knife assembly 1, and to cut and crush the food in multiple places in the food processing chamber during operation, and on the other hand, the compatibility of the food processor can be improved by designing the knives 20, and it can be suitable for food of various forms, volumes and shapes.

[0057] Optionally, the first tool 21, the second tool 22 and the third tool 23 are respectively installed on the tool shaft 10 at preset intervals through the shaft sleeve 15, the third tool 23 is located at the bottom of the tool shaft 10 and is closest to the first end 11 of the tool shaft 10. After the third tool 23 is installed on the tool shaft 10, the first shaft sleeve 15 is sleeved on the tool shaft 10, and then the second tool 22 is installed on the tool shaft 10 and is located above the shaft sleeve 15, so that the second tool 22 and the third tool 23 are connected through the shaft sleeve 15. They are spaced apart at a preset distance; then a second sleeve 15 is sleeved on the knife shaft 10, and a first tool 21 is installed on the sleeve 15, and the first tool 21 and the second tool 22 are spaced apart at a preset distance through the sleeve 15; finally, the first tool 21 is locked at the top end of the knife shaft 10, that is, the second end 12 of the knife shaft 10, by a fastener 14 to complete the installation of the entire knife assembly 1, wherein the fastener 14 can be optionally a nut, and a gasket can be installed between the fastener 14 and the first tool 21 to prevent loosening.

[0058] Furthermore, the first end 11 can be directly connected to the driving member, or the first end 11 can also be installed with a tool holder 13, and a gasket can also be installed between the third tool 23 and the tool holder 13 to prevent loosening. Of course, a shaft sealing ring can also be installed between the third tool 23 and the tool holder 13 to increase sealing.

[0059] Exemplarily, the preset spacing between two adjacent sets of knives 20 is 5 mm to 20 mm. For example, the preset spacing between two adjacent sets of knives 20 can be 5 mm, 8 mm, 13 mm, 15 mm, 18 mm, 20 mm, etc. In this way, while ensuring that the knife assembly 1 has a sufficient whipping volume, it is possible to avoid the preset spacing between two adjacent sets of knives 20 being too large to affect the whipping and crushing effect of the food.

[0060] Please combine Figure 1 The tool 20 located in the middle, that is, the root of the second tool 22 is sleeved on the tool shaft 10, and the second tool 22 includes at least one first blade 221, and the first blade 221 includes a first blade portion 2211 and a second blade portion 2213. The first blade portion 2211 is connected to the root of the tool 20 and extends radially along the tool shaft 10. The second blade portion 2213 is connected to the farthest end of the first blade portion 2211 away from the tool shaft 10, and is extended upward or downward.

[0061] The first blade portion 2211 can be optionally arranged parallel to or at an angle with the horizontal plane, and can cut and crush the food in the middle layer when rotating. When the blade shaft 10 rotates, due to the centrifugal force, the food gathers around, so the blade portion farther from the blade shaft 10 has more contact with the food. The second blade portion 2213 of the embodiment of the present application is arranged at the farthest end of the first blade portion 2211 away from the blade shaft 10, so that it can fully contact the food, and because the second blade portion 2213 extends upward or downward, the range of action of the second blade portion 2213 is expanded, so that the second blade portion 2213 can fully cut and crush the food near it.

[0062] In an embodiment of the present application, the knife assembly 1 includes a knife shaft 10 and at least three groups of knives 20 arranged at axial intervals along the knife shaft 10. The at least three groups of knives 20 can cut and crush food when rotating with the knife shaft 10, so that the knife assembly 1 has a larger crushing space and good food compatibility.

[0063] In the blade of the cutter 20 located in the middle, the first blade 221 includes a first blade portion 2211 and a second blade portion 2213. The first blade portion 2211 extends along the radial direction of the cutter shaft 10, and the second blade portion 2213 is connected to the farthest end of the first blade portion 2211 away from the cutter shaft 10 and extends upward or downward. In this way, the second blade portion 2213 can fully contact the food and has a larger range of action, thereby improving the cutting and crushing effect of the food and improving the processing efficiency.

[0064] The present application improves the crushing effect of the knife assembly 1 by designing the knife shape of the knife 20, rather than adopting the method of increasing the output power of the driving part in the related technology. It can ensure good cost control while improving the crushing effect, and can avoid problems such as noise and vibration caused by increasing the output power, thereby ensuring the operating quality and user experience of the food processor.

[0065] In some embodiments, the extension direction of the second knife portion 2213 is set at an angle α with the axial direction of the knife shaft 10, wherein 0°<α≤10°. It can be understood that if the angle α is greater than 10 degrees, when the length of the second knife portion 2213 is constant, when the knife shaft 10 rotates, the height direction of the second knife portion 2213 has a smaller range of action, thereby affecting the crushing effect. This embodiment limits 0°<α≤10°, which enables the second knife portion 2213 to contact more with the food, thereby improving the crushing effect. α can be selected as 2°, 5°, 10°, etc., and is not limited here.

[0066] Further, the extension direction of the second blade portion 2213 is parallel to the axial direction of the blade shaft 10. In this way, the second blade portion 2213 extends vertically upward or downward, which can maximize the contact between the second blade portion 2213 and the food, thereby further improving the crushing effect of the blade assembly 1.

[0067] The cutting edge of the second blade portion 2213 is located on one side of the second blade portion 2213 along the rotation direction of the cutter 20, and is substantially the same as the extension direction of the second blade portion 2213. In one embodiment, the distance between the cutting edge of the second blade portion 2213 and the cutter shaft 10 is greater than or equal to the distance between the farthest end of the first blade portion 2211 away from the cutter shaft 10 and the cutter shaft 10. In other words, relative to the farthest end of the first blade portion 2211 away from the cutter shaft 10, the cutting edge of the second blade portion 2213 is either flush with the farthest end, or tilted in a direction further away from the cutter shaft 10. In this way, it can be ensured that the cutting edge of the second blade portion 2213 is always located at the outermost periphery of the second cutter 22, can contact the most dense part of the food, and can fully cut and crush the food.

[0068] Among them, the extension direction of the cutting edge of the second knife part 2213 is parallel to the axial direction of the knife shaft 10. Along the axial direction of the knife shaft 10, each cutting edge of the second knife part 2213 is located at the maximum straightness of the second knife 22, and can maximize the contact with the food and have a larger range of action, thereby further improving the cutting and crushing effect and improving the crushing efficiency.

[0069] In some embodiments, the first blade portion 2211 and the second blade portion 2213 are an integral structure. For example, the first blade portion 2211 and the second blade portion 2213 can be integrally cast, or after forming the first blade 221, the first blade 221 is bent away from the root of the second cutter 22 by stamping and bending, etc., to form the first blade portion 2211 and the second blade portion 2213. The first blade portion 2211 and the second blade portion 2213 arranged in one piece have good structural integrity, and the processing and molding are relatively simple and convenient, and the production efficiency is high. Among them, the first blade 221 also includes an arc-shaped transition portion connected between the first blade portion 2211 and the second blade portion 2213 to reduce stress concentration and improve the strength and service life of the first blade 221.

[0070] Of course, the first blade portion 2211 and the second blade portion 2213 may also be welded after being formed separately to form the first blade 221 , and the embodiment of the present application does not impose any limitation on this.

[0071] In order to further increase the crushing space, the tool 20 (second tool 22) located in the middle of the tool assembly 1 further includes a second blade 223. The second blade 223 extends outwardly in a direction opposite to the extension direction of the second blade portion 2213.

[0072] Please refer to Figure 1 and Figure 2 In some embodiments, the first blade portion 2211 extends radially along the blade shaft 10, and the second blade portion 2213 extends downward. Obviously, on the side opposite to the extension direction of the second blade portion 2213, that is, there is a large space between the first blade 221 and the first cutter 21 located above, the second blade 223 extends upward and is tilted outward relative to the blade shaft 10. In this way, when the second cutter 22 rotates with the blade shaft 10, the second blade 223 can crush the food between the first blade 221 and the first cutter 21, which not only increases the crushing space of the knife assembly 1, but also prevents the food from being stuck between the first blade 221 and the first cutter 21, further improving the crushing effect of the knife assembly 1.

[0073] Furthermore, the second blade 223 is set at an angle β with the horizontal plane, and the angle β satisfies the relationship of 30°≤β≤50°. It can be understood that if the angle β is greater than 50 degrees, the second blade 223 has a large bending angle relative to the root of the second cutter 22, which is difficult to produce and the structural strength is easily affected. At the same time, if the angle between the second blade 223 and the first blade 221 is too large, it is easy to cause food to get stuck. In addition, if the angle between the second blade 223 and the knife shaft 10 is too small, it is easy to cause food to accumulate and difficult to clean; and if the angle β is less than 30°, it is also easy to cause food to get stuck, and the crushing space of the knife assembly 1 will be smaller, affecting the crushing effect. Therefore, the embodiment of the present application is limited to 30°≤β≤50°, which can increase the crushing space of the knife assembly 1, avoid food from getting stuck, improve the crushing effect, and also facilitate the molding and cleaning of the second blade 223. Among them, β can be selected as 35°, 40°, 50°, which is not limited here.

[0074] In one embodiment, β is 45°. Under the action of centrifugal force, part of the food will be thrown obliquely along the second blade 223 to the periphery of the cup body. On the basis of the above beneficial effects, when β is 45°, the food can have a larger movement distance, and more food can be gathered around the cup body, so that the second blade 2213 can be fully in contact with the food, and the crushing effect is further improved.

[0075] Of course, if Figure 2 As shown, in some embodiments of the present application, the second knife portion 2213 may extend upward and the second blade 223 may extend downward, which can also have the above-mentioned beneficial effects and will not be elaborated herein.

[0076] Please refer to Figure 1 In the embodiment of the present application, the second cutter 22 includes at least two first blades 221 and at least two second blades 223, and each second blade 223 extends outwardly along a direction opposite to the extension direction of the second blade portion 2213, thereby increasing the contact area between the knife assembly 1 and the food material and increasing the crushing space of the knife assembly 1. Along the circumference of the knife shaft 10, at least two first blades 221 and at least two second blades 223 are alternately arranged, and the blade arrangement is more even, so that the crushed food material is more delicate. For example, the second cutter 22 includes two first blades 221 and two second blades 223, and the two first blades 221 are symmetrically arranged about the knife shaft 10, and the two second blades 223 are symmetrically arranged about the knife shaft 10. In this way, the weight of the knife assembly 1 can be evenly distributed, thereby improving the operating stability of the knife assembly 1.

[0077] Please refer to Figure 1Among the blades of the cutter 20 located below, that is, the blades of the third cutter 23, at least one blade includes a third blade portion 231 and a fourth blade portion 233. The third blade portion 231 is connected to the root of the third cutter 23 and extends radially along the cutter shaft 10. The fourth blade portion 233 is connected to the farthest end of the third blade portion 231 away from the cutter shaft 10 and extends upward or downward. During the operation of the food processor, the food moves to the bottom of the cup body under the action of gravity. It can be understood that the surroundings of the cup body are areas where the food is relatively dense. The embodiment of the present application allows the fourth blade portion 233 located below to extend upward or downward, so as to more fully contact the food, and cooperate with the second blade portion 2213 to further cut and crush the food, thereby further improving the crushing effect.

[0078] In some embodiments, the extension direction of the fourth knife portion 233 is set at an angle γ with the axial direction of the knife shaft 10, wherein 0°<γ≤10°. It can be understood that if the angle γ is greater than 10 degrees, when the length of the fourth knife portion 233 is constant, when the knife shaft 10 rotates, the height direction of the fourth knife portion 233 has a smaller range of action, thereby affecting the crushing effect. This embodiment limits 0°<γ≤10°, which enables the fourth knife portion 233 to contact more food materials and improve the crushing effect. γ can be selected as 2°, 5°, 10°, etc., and is not limited here.

[0079] Further, the extension direction of the fourth blade portion 233 is parallel to the axial direction of the blade shaft 10. In this way, the fourth blade portion 233 extends vertically upward or downward, which can maximize the contact between the fourth blade portion 233 and the food, thereby further improving the crushing effect of the blade assembly 1.

[0080] Combination Figure 1 In one embodiment, the fourth blade portion 233 and the second blade portion 2213 are arranged toward each other. In this embodiment, the second blade portion 2213 extends downward, and the fourth blade portion 233 extends upward, so that the second blade portion 2213 and the fourth blade portion 233 can play a better synergistic role, and the food near the second blade portion 2213 and the fourth blade portion 233 is crushed more thoroughly, making the food more delicate.

[0081] Optionally, the second blade portion 2213 and the fourth blade portion 233 may be located on the same straight line along the height direction so as to be able to cut and crush food near both at the same time, or the second blade portion 2213 and the fourth blade portion 233 may also be staggered to avoid interference.

[0082] Of course, in other embodiments of the present application, the second blade portion 2213 and the fourth blade portion 233 may both extend upward or downward, or when the second blade portion 2213 extends upward, the fourth blade portion 233 extends downward opposite thereto, and the embodiments of the present application are not limited to this.

[0083] In some embodiments, the third blade portion 231 can only extend along the radial direction of the blade shaft 10, and the structure is simple and easy to manufacture. In other embodiments, at least part of the third blade portion 231 is lower than the root of the third blade 23. It can be understood that there is still a partial gap between the root of the third blade 23 and the bottom wall of the cup body. The food is deposited at the bottom of the cup body under the action of gravity. The part of the third blade portion 231 below the root of the third blade 23 can disturb the food at the bottom and cut and crush it, thereby improving the crushing effect. Furthermore, the part of the third blade portion 231 below the root of the third blade 23 is parallel to the horizontal plane, so that the part is in more sufficient contact with the food.

[0084] Please refer to Figure 1 In one embodiment, the third blade portion 231 includes a first connecting segment 2311 and a second connecting segment 2313. The first connecting segment 2311 is connected to the root of the third blade 23 and extends obliquely downward away from the blade shaft 10. The second connecting segment 2313 is connected to an end of the first connecting segment 2311 away from the blade shaft 10 and extends along the radial direction of the blade shaft 10 and is parallel to the horizontal plane. An end of the second connecting segment 2313 away from the first connecting segment 2311 is connected to the fourth blade portion 233. In this way, in this embodiment, the second connecting segment 2313 is closer to the bottom wall of the cup body than the root of the third blade 23, so that the food at the bottom of the cup body is fully cut, the crushing space is increased, and the crushing effect is improved.

[0085] It can be understood that the first connecting section 2311 and the second connecting section 2313 can be split components or an integral structure. Furthermore, the third blade portion 231 and the fourth blade portion 233 can also be split components or an integral structure, which is not limited in the present embodiment. Among them, for the embodiment in which the third blade portion 231 and the fourth blade portion 233 are an integral structure, the third blade portion 231 and the fourth blade portion 233 can be integrally cast, or formed by stamping and bending after the blade is formed. For example, the blade of the third knife 23 can be bent for the first time relative to the root so that it extends obliquely downward away from the knife shaft 10, and then the blade portion is bent for the second time to form the first connecting section 2311 and the second connecting section 2313, and the end of the second connecting section 2313 away from the first connecting section 2311 is bent upward or downward to form the fourth blade portion 233.

[0086] In the embodiment of the present application, the third tool 23 includes at least two blades, and the at least two blades are symmetrically arranged about the central axis of the tool shaft 10 so that the blades are evenly distributed, thereby improving the operating stability and the crushing effect.

[0087] In some embodiments, in the blade of the tool 20 (first tool 21) located above, the blade is bent upward and forms an angle of 45° to 80° with the horizontal plane. For example, in the blade of the first tool 21, the blade is bent upward and can form an angle of 45°, 50°, 65°, 70°, 77°, 80°, etc. with the horizontal plane. In this way, the blade of the first tool 21 forms a larger whipping volume during the rotation process to fully whip different parts of the food, so that the crushed food is more delicate, so as to achieve a better crushing effect. Specifically, the first tool 21 may include two blades, and the two blades may be arranged symmetrically along the central axis of the knife shaft 10 to achieve better whipping and crushing effects.

[0088] Combination Figures 1 to 3 In some embodiments, the number of blades of the cutter 20 located in the middle is greater than the number of blades of the cutters 20 located on both sides thereof. That is, the number of blades of the second cutter 22 is greater than the number of blades of the third cutter 23 and the number of blades of the first cutter 21. For example, the second cutter 22 has four blades, and the first cutter 21 and the third cutter 23 each have two blades. In this way, the number of blades of each set of cutters 20 can be set differently, so that the crushed food is more delicate, especially for food without liquid, a good crushing effect can also be achieved, so as to further solve the problem of poor food crushing effect.

[0089] like Figure 3 As shown, in one embodiment, along the same rotation direction, the blades of two adjacent groups of cutters 20 are staggered so that different angles are formed between the blades of the two adjacent groups of cutters 20, thereby achieving a larger whipping volume, so that the contact position of each layer of cutters 20 with the food is different, making the crushed food more delicate, thereby achieving a better crushing effect.

[0090] Optionally, at least part of the cutting edge of the blade of the third knife 23 faces upward, at least part of the cutting edge of the blade of the second knife 22, and the cutting edge of the blade of the first knife 21 all face downward, which not only makes the knife assembly 1 whipping a larger volume of food, but also improves the disturbance effect of the knife assembly 1 on the food, making the whipped food more uniform and delicate.

[0091] Of course, on the basis of the above technical solution, the contact area between the cutter 20 and the food material can be increased by setting at least part of the blade of the cutter 20 to be serrated, thereby further improving the crushing effect, which will not be elaborated here.

[0092] The above is an explanation of the knife assembly 1 proposed in the embodiment of the present application. Since the cup body assembly and food processor proposed in the embodiment of the present application adopt all the technical solutions of all the above embodiments, they at least have all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here one by one.
