Description

Technical Field

[0001] This utility model relates to the field of food processor technology, specifically to a multi-functional food processor blade structure. Background Technology

[0002] A food processor is a multi-functional kitchen appliance that primarily uses high-speed rotating blades to cut, pulverize, and blend ingredients to meet various cooking needs. However, the single-shaped blades used in existing food processors cause the fluid inside the container to form a single-planar vortex, resulting in stratified flow and dead zones in the vortex. This leads to poor mixing uniformity and a lack of a secondary cutting mechanism for splashed ingredients, resulting in unevenly pulverized particles, a single cutting path, and incomplete pulverization of tough ingredients.

[0003] Chinese invention patent application number 201710039582.8 discloses a pulverizing blade and a food processor. The pulverizing blade includes a mounting shaft, which has a mounting end and a connecting end; at least one first blade mounted on the mounting shaft, the first blade having a first cutting edge disposed on the side of the first blade away from the mounting end; and at least one second blade mounted on the mounting shaft, the second blade having a second cutting edge disposed on the side of the second blade near the mounting end. The first blade and / or the second blade are mounted obliquely on the mounting shaft, and the thickness of both blades is H, with a value of 1mm ≤ H ≤ 5mm. The second cutting edge's extraction of material fills the gaps formed during material circulation, thereby reducing material fluctuations, improving pulverizing efficiency and effect, reducing product noise and frictional heat generation, and lowering product temperature rise. However, this patented technology also has the following drawbacks: the crushing blade relies solely on the inclined installation of the first and second blades to guide the material flow. The blade design is relatively simple, which can only achieve basic unidirectional or planar circulation, easily forming "laminar flow," resulting in the material not being fully mixed and exhibiting stratification or local accumulation. Summary of the Invention

[0004] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a multi-functional food processor blade structure.

[0005] The purpose of this utility model is achieved through the following technical solution: a multi-functional food processor blade structure, including a blade shaft and a cross blade and a straight blade that are sequentially sleeved and fixed to the top of the blade shaft from bottom to top. The cross blade includes a first connecting piece sleeved and fixed to the top of the blade shaft, two first blades that are centrally symmetrically inclined and fixed downward on the left and right sides of the first connecting piece, and two second blades that are centrally symmetrically inclined and fixed upward on the front and rear sides of the first connecting piece. The straight blade includes a second connecting piece sleeved and fixed to the top of the blade shaft, and two third blades that are symmetrically inclined and fixed upward on the left and right sides of the second connecting piece. The two first blades and the two second blades each have an arc-shaped notch in the middle. The side of the two first blades that is away from the blade edge corresponding to the arc-shaped notch is bent upward in an arc shape, and the side of the two second blades that is away from the blade edge corresponding to the arc-shaped notch is bent downward in an arc shape. The positions of the two first blades and the two third blades correspond one-to-one.

[0006] Furthermore, each of the first blades is provided with a first cutting edge, and each of the second blades is provided with a second cutting edge. The orientation of the first and second cutting edges is consistent with the rotation direction of the blade shaft, and both the first and second cutting edges are provided with a plurality of serrations.

[0007] Furthermore, each of the third blades has a third cutting edge at the top and on both sides of the top.

[0008] Furthermore, a positioning protrusion is fixed at the top of the cutter shaft, and an external thread is provided at the bottom of the cutter shaft. A first mounting hole and a second mounting hole are respectively opened in the middle of the first connecting piece and the second connecting piece. The positioning protrusion passes through the first mounting hole and the second mounting hole from bottom to top.

[0009] Furthermore, the angle between each of the first blades and the first connecting piece is 130-160°, and the angle between each of the second blades and the first connecting piece is 130-160°.

[0010] Furthermore, the included angle between each of the third blades and the second connecting piece is 110-140°.

[0011] Furthermore, the angle between each second blade and the first connecting piece is greater than the angle between each third blade and the second connecting piece.

[0012] Furthermore, the two first blades, the two second blades, and the first connecting piece are integrally formed.

[0013] The beneficial effects of this utility model are as follows: The multi-functional food processor blade structure of this utility model achieves strong three-dimensional turbulence in the food processor cup through a unique combination design of cross blades and straight blades, supplemented by the arc-shaped notch of the blade and the arc-shaped bending structure on the side away from the blade edge. This enhances the secondary cutting of splashed ingredients and reduces fiber entanglement, thereby significantly improving the uniformity of mixing and the fineness of cutting and crushing. It also greatly reduces the dead corners of mixing and enhances the food processor's ability to process a variety of ingredients, ultimately achieving a high-efficiency, uniform, and multi-functional effect.

Detailed Implementation

[0018] To facilitate understanding by those skilled in the art, the following description is provided in conjunction with embodiments and appendices. Figure 1-3 The present invention will be further described below. The content mentioned in the embodiments is not intended to limit the present invention.

[0019] See Figure 1-3 A multi-functional food processor blade structure includes a blade shaft 1 and two blades, a cross blade 2 and a straight blade 3, which are sequentially fitted and fixed to the top of the blade shaft 1 from bottom to top. The cross blade 2 includes a first connecting piece 21 fitted and fixed to the top of the blade shaft 1, two first blades 22 that are centrally symmetrically inclined downward and fixed to the left and right sides of the first connecting piece 21, and two second blades 23 that are centrally symmetrically inclined upward and fixed to the front and rear sides of the first connecting piece 21. The straight blade 3 includes a second connecting piece 31 fitted and fixed to the top of the blade shaft 1 and two third blades 32 that are symmetrically inclined upward and fixed to the left and right sides of the second connecting piece 31. The two first blades 22 and the two second blades 23 each have an arc-shaped notch 24 in the middle. The side of the two first blades 22 that is away from the blade edge corresponding to the arc-shaped notch 24 is bent upward in an arc shape, and the side of the two second blades 23 that is away from the blade edge corresponding to the arc-shaped notch 24 is bent downward in an arc shape. The positions of the two first blades 22 and the two third blades 32 correspond one-to-one.

[0020] The multi-functional food processor blade structure of this invention features a unique combination design of a cross blade 2 and a straight blade 3, supplemented by an arc-shaped notch 24 on the blade and an arc-shaped bending structure on the side away from the blade edge. This achieves strong three-dimensional turbulence within the food processor cup, enhancing the secondary cutting of splashed ingredients and reducing fiber entanglement. Consequently, it significantly improves the uniformity of mixing and the fineness of cutting and pulverizing, greatly reduces dead zones in the mixing process, and enhances the food processor's ability to handle a variety of ingredients, ultimately achieving a highly efficient, uniform, and multi-functional effect.

[0021] In this embodiment, each of the first blades 22 is provided with a first cutting edge 221, and each of the second blades 23 is provided with a second cutting edge 231. The orientation of the first cutting edge 221 and the second cutting edge 231 is consistent with the rotation direction of the blade shaft 1, and both the first cutting edge 221 and the second cutting edge 231 are provided with a plurality of serrations 25. Setting the orientation of the first cutting edge 221 and the second cutting edge 231 to the same direction as the rotation direction of the blade shaft 1 allows the blade to effectively cut food during rotation, reducing cutting resistance and thus improving cutting efficiency. The serrations 25 can increase the cutting area and cutting force of the blade, making it easier for the blade to cut tougher food, such as vegetables and fruits.

[0022] In this embodiment, each of the third blades 32 has a third cutting edge 321 on its top and both sides. This multi-faceted cutting improves its cutting efficiency.

[0023] In this embodiment, a positioning protrusion 11 is fixed to the top of the cutter shaft 1, and an external thread 12 is provided at the bottom of the cutter shaft 1. A first mounting hole 211 and a second mounting hole 311 are respectively opened in the middle of the first connecting piece 21 and the second connecting piece 31. The positioning protrusion 11 passes through the first mounting hole 211 and the second mounting hole 311 from bottom to top. The above structure facilitates the installation of the cross blade 2 and the slotted blade 3.

[0024] In this embodiment, the included angle between each first blade 22 and the first connecting piece 21 is 130-160°, and the included angle between each second blade 23 and the first connecting piece 21 is 130-160°. To achieve the best performance of this invention, the included angle between each first blade 22 and the first connecting piece 21 is set to 150°, and the included angle between each second blade 23 and the first connecting piece 21 is set to 150°.

[0025] In this embodiment, the included angle between each of the third blades 32 and the second connecting piece 31 is 110-140°. To achieve the best performance of this invention, the included angle between each of the third blades 32 and the second connecting piece 31 is set to 130°.

[0026] In this embodiment, the angle between each second blade 23 and the first connecting piece 21 is greater than the angle between each third blade 32 and the second connecting piece 31. By utilizing the difference in angles between the second blade 23, the third blade 32, and the connecting piece, a "throw-and-cut" three-dimensional flow field is constructed, combining coarse cutting at the bottom layer with fine cutting at the top layer. This improves the uniformity of food crushing, reduces entanglement, and is suitable for processing both hard and soft ingredients.

[0027] In this embodiment, the two first blades 22, the two second blades 23, and the first connecting piece 21 are integrally formed. The integrally formed cross blade can effectively resist the impact and torsional forces during cutting, reducing the risk of breakage or deformation.

[0028] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this utility model are within the protection scope of this utility model.
