Description

Technical Field

[0001] This utility model relates to the field of stirring blade structure technology, specifically to a stirring assembly with three layers of blades and its blending machine. Background Technology

[0002] As living standards improve, more and more families are using food blenders to process ingredients and cook food, such as juicing fruits and grinding soybeans into soy milk. Food blenders need to provide functions including cutting and mixing, both of which are usually achieved by blades with rotating functions, such as sharpening the blades to cut ingredients, or bending the blades at a certain angle to mix the fluids inside the blender.

[0003] For example, patent document CN208176472U discloses a juicer blade assembly structure, which uses a single layer of blades bent at different angles to perform multiple functions such as stirring and cutting. However, because the blades are not symmetrical in the circumferential direction, the stress on the blades is uneven during rotation, resulting in poor stirring and cutting effects.

[0004] For example, patent document CN210697375U discloses a high-efficiency sealed blade assembly for a food blender, which includes an upper blade and a lower blade. In such blending blades, the upper blade has upward-bent blades, typically responsible for generating upward-tumbling vortices; the lower blade has flat blades, typically responsible for cutting food. However, the two blades are fixed together, preventing them from performing their precise functions, and the upper blade also partially cuts the food. However, due to the bent structure of the upper blade, the cutting effect is poor. In particular, when both blades rotate synchronously, the cutting effect of the upper blade affects the rotation efficiency, which in turn affects the cutting effect of the lower blade. Summary of the Invention

[0005] In response to the problems in related technologies, this utility model proposes a mixing assembly with three layers of blades and its blender, which can effectively improve the overall cutting effect of the mixing assembly on food.

[0006] This utility model is implemented as follows:

[0007] A stirring assembly with three layers of blades is applied to a food processing device for stirring and pulverizing food. It includes a rotatable blade shaft with three blades fixedly mounted on it: a first blade, a second blade, and a third blade. Each blade has an even number of blades, with several blades on the same blade spaced equidistant and centrally symmetrical about the blade shaft. The blades are sharpened. The blades on the first, second, and third blades are respectively designated as the first blade, the second blade, and the third blade.

[0008] The first and second blades are fitted together, with the second blade located above or below the first blade; the free end of the second blade extends vertically toward the outer periphery of the blade shaft; the free end of the first blade extends obliquely upward or downward toward the outer periphery of the blade shaft; some or all of the first blades cover the second blades; the third blade is close to the top of the blade shaft, and there is a gap between the third blade and the second blade or the first blade.

[0009] On the cutter shaft, the first and second cutters, located at the lower position, are responsible for the main food cutting operations during operation. The blades are centrally symmetrical to ensure even force distribution.

[0010] With the axial top of the cutter shaft as the vertical upward direction, the first blade can extend obliquely upward or obliquely downward relative to the second blade; when the first cutter is located below the second cutter, some or all of the first blades extend obliquely downward; when the first cutter is located above the second cutter, some or all of the first blades extend obliquely upward; whereby, after the first blade extends obliquely downward, during rotational cutting, the food can be brought as close as possible to the bottom of the cutter, so as not to roll upward and move away from the first cutter.

[0011] The first blade, extending partially upwards and partially downwards, works in combination, spaced apart to create a larger cutting range, allowing the food to float within that range. The second blade is positioned either below or above the first blade extending downwards. This second blade is a straight blade and forms an angle with the first blade, assisting it in cutting. Both blades cut the food synchronously, resulting in superior cutting performance. The rotation of the third blade does not interfere with the other two blades.

[0012] The third cutter is spaced apart from the first or second cutter to avoid interference between the first and third blades in the obliquely upward-extending section.

[0013] As a further optimization of the above solution, the food processing device has a stirring chamber, and the stirring component is vertically disposed at the center of the bottom surface of the stirring chamber; the second blade is parallel to the bottom surface; the angle formed by the first blade relative to the bottom surface is 5° to 45°.

[0014] Preferably, the angle at which the first blade extends obliquely upward or downward is between 15° and 30°. The optimal angle for the first blade to extend obliquely upward or downward is 15°.

[0015] As a further optimization of the above scheme, the vertical distance between the free end of the first blade extending obliquely downward and the bottom surface is 3mm-13mm. That is, the vertical distance between the end of the downward-curving first blade and the bottom surface is 3mm-13mm.

[0016] Preferably, the vertical distance is 5mm.

[0017] As a further optimization of the above scheme, the second blade is smaller than the first blade; the length of the second blade is 1 / 3 to 4 / 5 of the length of the first blade.

[0018] As a further optimization of the above solution, the middle section of the cutter shaft is a support platform; the cutter shaft retracts above the support platform to form a limiting part;

[0019] The cutting tool has a through-hole at its center; the cutting tool is fitted onto the limiting part, and the through-hole matches the limiting part;

[0020] The first or second cutting tool abuts against the upper surface of the support portion.

[0021] As a further optimization of the above solution, the limiting part is formed as a flat part.

[0022] The flat design facilitates the machining of the tool shaft and ensures that the limiting part of the tool shaft and the tool are fixedly connected to each other.

[0023] As a further optimization of the above solution, a limiting ring is sleeved on the outer peripheral side of the cutter shaft; the upper surface of the limiting ring abuts against the third cutter; and the lower surface of the limiting ring abuts against the first cutter or the second cutter.

[0024] A gap is created between the third tool and the other two tools by using a limiting ring.

[0025] As a further optimization of the above solution, the top of the cutter shaft is formed as a riveting part; after assembly, the riveting part protrudes from the third cutter.

[0026] After riveting, the riveting part fixes the first tool, the second tool, and the third tool downwards.

[0027] The riveting process involves applying pressure from top to bottom towards the top of the riveting part. During riveting, under pressure, the limiting part deforms circumferentially, squeezing the cutting tool and making the tool more securely fixed. At the same time, the riveting part itself deforms, forming a limiting structure that prevents the cutting tool from separating upwards.

[0028] As a further optimization of the above scheme, the free end of the third blade extends upward or obliquely upward toward the outer periphery of the cutter shaft.

[0029] The third blade can both cut and stir. When stirring, it creates an upward swirling vortex in the fluid, which helps to evenly mix the delicate ingredients with the fluid.

[0030] This utility model also provides a blender, including a shell and a stirring chamber disposed inside the shell; the bottom of the stirring chamber is a heat-conducting part; the blender is also provided with a drive unit and a heating unit, and the heat generated by the heating unit is conducted to the stirring chamber through the heat-conducting part; the blender also uses the above-mentioned stirring assembly with three layers of blades, and the drive unit is connected to the blade shaft of the stirring unit.

[0031] The beneficial effects are as follows:

[0032] This invention provides a mixing assembly with three blades and a corresponding blender. The assembly features a first and second blade that fit closely together, with the first blade partially or completely covering the second blade. When part of the first blade extends obliquely, it forms an angle with the second blade. The first and second blades rotate synchronously to cut the food, resulting in superior cutting performance compared to existing technologies. The symmetrical arrangement of the blades ensures even force distribution across the entire assembly. The downward-sloping extension of the first blade allows the food to stay as close to the bottom of the blade as possible during rotational cutting, preventing it from rolling upwards or moving away from the first blade. Alternatively, a combination of partially upward-sloping and partially downward-sloping first blades can achieve a larger cutting range, allowing the food to float within that range.

[0049] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0050] Example 1

[0051] like Figures 1 to 5 As shown, this embodiment provides a high-speed blender, including a housing 1 and a mixing chamber 2 disposed inside the housing 1; the bottom of the mixing chamber 2 is a heat-conducting part 3; the blender also includes a drive unit 5 (such as a motor) and a heating unit 4 (such as a heating plate), the heat generated by the heating unit 4 is conducted to the mixing chamber 2 through the heat-conducting part 3; the blender also uses a mixing assembly 6 with three layers of blades as described above. In this embodiment, the mixing assembly 6 is vertically disposed at the center of the bottom surface of the mixing chamber 2.

[0052] Specifically, a stirring assembly 6 with three layers of blades is applied to a food processing device for stirring and crushing food; it includes a rotatable blade shaft 61; and a drive unit 5 is connected to the blade shaft 61 of the stirring unit.

[0053] In this embodiment, the middle section of the cutter shaft 61 is a support portion 611; the cutter shaft 61 retracts above the support to form a limiting portion; in this embodiment, the limiting portion is formed as a flat portion 612. The flat portion 612 facilitates the machining of the cutter shaft 61 and makes the limiting portion of the cutter shaft 61 and the cutting tool fixedly connected to each other.

[0054] Three cutting tools are fixedly mounted on the cutter shaft 61, including a first cutting tool 62, a second cutting tool 63, and a third cutting tool 64. Each cutting tool has a through-hole 67 at its center. The cutting tools are fitted onto a limiting part, with the through-hole 67 matching the limiting part. The first cutting tool 62 abuts against the upper surface of the support portion 611. The first cutting tool 62 and the second cutting tool 63 are fitted together, with the second cutting tool 63 located above the first cutting tool 62. The third cutting tool 64 is close to the top of the cutter shaft 61, and there is a gap between the third cutting tool 64 and the second cutting tool 63.

[0055] In this embodiment, a limiting ring 65 is sleeved on the outer peripheral side of the cutter shaft 61; the upper surface of the limiting ring 65 abuts against the third cutter 64; the lower surface of the limiting ring 65 abuts against the first cutter 62 or the second cutter 63. The limiting ring 65 creates a gap between the third cutter 64 and the second cutter 63.

[0056] In this embodiment, the top of the cutter shaft 61 is formed as a riveting part 613; after assembly, the riveting part 613 protrudes from the third cutter 64;

[0057] After riveting, the riveting part 613 fixes the first cutting tool 62, the second cutting tool 63 and the third cutting tool 64 downward.

[0058] The riveting process involves applying pressure from top to bottom towards the top of the riveting part 613. During riveting, under pressure, the limiting part deforms circumferentially, squeezing the tool and making the tool more securely fixed. At the same time, the riveting part 613 itself deforms, forming a limiting structure that prevents the tool from separating upwards.

[0059] Each tool has an even number of blades, and several blades on the same tool are spaced at the same interval and are centrally symmetrical about the tool axis 61; the blades are sharpened; the blades are radially spread on the tool axis 61.

[0060] In this embodiment, the first cutting tool 62 has four first blades 621; the second cutting tool 63 has two second blades 631; and the third cutting tool 64 has four third blades 641.

[0061] The first cutter 62 and the second cutter 63 are fitted together, with the second cutter 63 located above the first cutter 62. Two first blades 621 respectively cover two second blades 631. The second blades 631 are parallel to the bottom surface. The free ends of the two covered first blades 621 extend obliquely downward relative to the second blades 631. The other two first blades 621 extend obliquely upward. At this time, the obliquely upward and obliquely downward first blades 621 are spaced apart.

[0062] The angle at which the first blade 621 extends obliquely upward or downward relative to the bottom surface is 15°. In this embodiment, the vertical distance between the free end of the obliquely downward extending first blade 621 and the bottom surface is 5mm. In this embodiment, the second blade 631 is smaller than the first blade 621, and the length of the second blade 631 is half that of the first blade 621.

[0063] In this embodiment, the free end of the third blade 641 extends obliquely upward toward the outer periphery of the cutter shaft 61 (not shown).

[0064] On the cutter shaft 61, the first cutter 62 and the second cutter 63, located at the lower position, are responsible for the main food cutting operation during operation. The blades are centrally symmetrical to ensure even force distribution.

[0065] The first blade 621 extends obliquely downwards, allowing the food to be as close as possible to the bottom of the blade during rotational cutting, preventing it from rolling upwards and away from the first blade 62.

[0066] The combination of the first blade 621 extending obliquely upward and the first blade 621 extending obliquely downward can achieve a larger cutting range, allowing the food to float within the cutting range.

[0067] The first blade 621, which extends partially upwards and partially downwards, works in combination, with the two blades spaced apart to achieve a larger cutting range, allowing the food to float within this range. At this point, the second blade 631 is located only above the downwardly extending first blade 621. The third blade 64 is spaced apart from either the first blade 621 or the second blade 63 to avoid interference between the upwardly extending first blade 621 and the third blade 641. The third blade 64 can both cut and stir; during stirring, it creates an upward-rolling vortex in the fluid, ensuring a uniform mixing of the delicate food and fluid.

[0069] This implementation example Figure 6 As shown, features not explained in this embodiment are explained using the method described in Embodiment 1, and will not be repeated here. The difference between this embodiment and Embodiment 1 is:

[0070] In this embodiment, the second cutter 63 abuts against the upper surface of the support portion 611. The second cutter 63 is located below the first cutter 62. The lower surface of the limiting ring 65 abuts against the first cutter 62, creating a gap between the third cutter 64 and the first cutter 62.

[0071] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the utility model should also fall within the protection scope of the claims of this utility model.
