Description

Technical Field

[0001] This utility model relates to the field of smoothie machine technology, specifically to a smoothie machine and its stirring blades. Background Technology

[0002] A smoothie maker is a food processing device widely used in beverage shops, fast food restaurants, and homes. It is mainly used to mix and blend ingredients such as ice, fruit, and dairy products to create a smooth smoothie or cold drink. Its core components include a motor, a mixing cup, mixing blades, and a control system. During operation, the motor drives the mixing blades to rotate at high speed, crushing and mixing the ingredients in the cup to ultimately form a uniform smoothie mixture.

[0003] However, some existing smoothie machines have a problem with uneven mixing during the mixing process, specifically manifested as follows:

[0004] Unreasonable fan blade design: Some models use simple straight blades for the mixing fan blades, which results in a single flow direction of raw materials during mixing. Ice cubes and ingredients are prone to forming local eddies in the mixing cup, while other areas are not mixed sufficiently, affecting the texture of the finished product.

[0005] Low mixing efficiency: Poor design of the size or angle of some fan blades results in insufficient mixing force, requiring longer mixing time to achieve the desired effect, affecting efficiency, and may cause the motor to overheat due to prolonged high-speed operation.

[0006] The aforementioned problems not only reduce the taste and quality of smoothies but may also lead to increased energy consumption and accelerated wear of the equipment. Therefore, it is urgent to optimize the structural design of the mixing blades to enable them to crush and mix raw materials more efficiently and evenly, thereby improving the overall performance of the smoothie machine. Utility Model Content

[0007] The purpose of this invention is to provide a smoothie maker and its mixing blades to improve the problem of uneven mixing in existing mixing blades.

[0008] To achieve the above objectives, the technical solution of this utility model is as follows:

[0009] A stirring fan blade includes a bottom ring, a bushing, two scrapers, and two ribs. The ribs and the bushing are arranged perpendicular to the plane of the bottom ring. The two scrapers are spiral-shaped, with one end connected to the bottom ring and the other end connected to the bushing. The middle section and the part near the bushing of the two scrapers are respectively connected to the two ribs, and the bottom of the ribs are connected to the bottom ring. The outer side of the scrapers is provided with serrations.

[0010] Preferably, a protrusion is provided at the connection between the rib and the scraper to increase the connection area with the scraper.

[0011] Preferably, the serrations are located in the middle section of the scraper and near the bushing.

[0012] Preferably, the ribs and the scraper are distributed at equal intervals on the bottom ring.

[0013] Preferably, the ribs and the scraper are distributed crosswise on the bottom ring.

[0014] Preferably, the bushing is provided with a vent hole.

[0015] Preferably, the bottom ring is a circular ring.

[0016] Preferably, the bushing is cylindrical.

[0017] Preferably, a reinforcing portion is provided between the scraper and the bottom ring.

[0018] A smoothie maker, comprising the aforementioned stirring blades.

[0019] Compared with the prior art, the slush machine and its stirring blade of this application have the following beneficial effects:

[0020] The stirring blades of this invention, by setting two spiral scrapers in combination with a rib structure, can form a multi-directional vortex, which allows ice and ingredients to be fully circulated and broken during the stirring process, avoiding local accumulation or stratification, and significantly improving the uniformity of stirring.

[0021] The serrations on the outside of the scraper further enhance its crushing ability, especially for ice or hard ingredients, reducing uncrushed residue and ensuring a smooth shaved ice texture.

[0022] The connection structure between the ribs and the scraper (such as the protrusion design) enhances the overall rigidity, making the fan blades more stable when rotating at high speed, more efficient in energy transfer, and shorter in mixing time.

[0023] The synergistic effect of the spiral scraper and ribs optimizes the fluid movement path, reduces ineffective stirring areas, and improves raw material processing efficiency.

[0024] The design of ribs and scrapers being evenly spaced or intersecting balances the stress, avoids localized wear, and extends service life. Attached Figure Description

[0028] Figure 4 This is a schematic diagram of the structure of the smoothie machine provided in an embodiment of the present invention. Detailed Implementation

[0029] The following detailed description illustrates the specific implementation method:

[0030] The reference numerals in the accompanying drawings include: bottom ring 1, bushing 2, scraper 3, rib 4, serration 5, protrusion 6, vent hole 7, and reinforcement 8.

[0031] like Figure 1-4 As shown, this embodiment provides a stirring blade for a smoothie maker and its application. This stirring blade, through a unique structural design, significantly improves stirring efficiency and mixing uniformity. The following description, in conjunction with the attached figure... Figure 1-3 The specific implementation of this embodiment will be described in detail.

[0032] In this embodiment, the stirring fan blade mainly includes core components such as a bottom ring 1, a bushing 2, two scrapers 3, and two ribs 4. The bottom ring 1 adopts a circular ring structure, providing stable foundation support for the entire fan blade. The bushing 2 is cylindrical and is set perpendicular to the plane of the bottom ring 1. The support plate is used to connect to the drive shaft of the smoothie machine. The two ribs 4 are also set vertically on the bottom ring 1 and arranged parallel to the bushing 2, together forming the support frame of the fan blade.

[0033] The two scrapers 3 feature a spiral design, with one end fixed to the edge of the bottom ring 1 and the other end connected to the bushing 2. This spiral structure generates multi-directional vortices during stirring, creating complex flow paths for the raw materials within the mixing cup. Particularly noteworthy is that the middle sections and the portion near the bushing 2 of the two scrapers 3 are connected to two reinforcing ribs 4, respectively. This multi-point fixing method significantly enhances the overall structural strength of the blades, preventing vibration and deformation during high-speed rotation.

[0034] A serrated structure 5 is provided on the outer edge of the scraper 3. These serrations 5 are mainly distributed in the middle section of the scraper 3 and the part near the bushing 2. The design of the serrations 5 significantly improves the crushing ability of the blades, especially the crushing effect on hard materials such as ice. When the blades rotate at high speed, the serrations 5 can effectively cut and crush the ice, ensuring that the final shaved ice has a smooth and uniform texture.

[0035] The connection between the rib 4 and the scraper 3 features a protrusion 6, which increases the connection area, improving structural strength and optimizing force transmission efficiency. In actual testing, this connection method ensures the fan blade remains stable even under high torque, effectively extending its service life.

[0036] From a spatial layout perspective, the ribs 4 and scrapers 3 are arranged at equal intervals on the bottom ring 1, although a cross-distribution arrangement can be adopted in practice. This arrangement ensures a balanced distribution of forces during mixing, avoids vibration problems caused by uneven force, and makes the flow of raw materials in the mixing cup more uniform.

[0037] In some embodiments, such as Figure 3 As shown, a reinforcing section 8 is provided between the scraper 3 and the bottom ring 1. The reinforcing section 8 blocks the angle between the bottom ring 1 and the scraper 3. The reinforcing section 8 has a curved surface, which allows the ice slush to be discharged along the curved surface of the reinforcing section 8 during the stirring process, resulting in more uniform stirring.

[0038] The bushing 2 has ventilation holes 7 inside, which effectively reduces air resistance generated during high-speed rotation and reduces energy loss. In practical applications, this improvement significantly reduces the motor load, not only improving energy efficiency but also extending the motor's service life.

[0039] When this stirring blade is applied to a smoothie machine, its performance advantages are fully demonstrated. In comparative tests, the stirring time using this embodiment is reduced by approximately 30% compared to traditional blades, and the uniformity of the finished smoothie is significantly improved. Particularly when processing raw materials containing a large amount of ice, no obvious uncrushed ice residue was found, fully demonstrating its excellent crushing ability.

[0040] In practice, the agitator blades can be made of food-grade stainless steel or high-strength engineering plastics. For commercial models, stainless steel is preferred to ensure durability; for household models, lightweight engineering plastics can be used. In terms of manufacturing process, a one-piece molding technology can be used to ensure the strong connection of each component, or a modular manufacturing and assembly method can be adopted for easy maintenance and replacement.

[0041] During use, the mixing blades demonstrated excellent adaptability. Whether making fruit smoothies, milkshakes, or other cold drinks, they ensured thorough mixing of ingredients. The unique spiral scraper design created a vortex effect that effectively prevented stratification of the ingredients during mixing. At the same time, the optimized structural design made cleaning and maintenance easier, with no hard-to-reach corners between the components.

[0042] Experimental data shows that by adopting the stirring blades of this embodiment, the overall energy efficiency ratio of the smoothie machine is improved by more than 25%. This is mainly due to the improved fluid dynamics design and reduced air resistance. Furthermore, the increased stirring efficiency and shorter single-cycle operation time significantly reduce heat generation during continuous operation, further enhancing reliability.

[0043] Another significant advantage of this stirring blade is its wide applicability. By adjusting parameters such as the spiral angle of the scraper 3 and the density of the serrations 5, it can be optimized for raw materials of different viscosities. For example, a smaller spiral angle design can be used for thicker milkshakes, while a denser serration design can be selected for drinks with a higher ice content.

[0044] In summary, the stirring blade of this embodiment, through its innovative structural design, effectively solves the problems of uneven mixing and low efficiency found in existing smoothie machines. Its unique spiral scraper 3, combined with the support structure of the ribs 4 and the optimized distribution of the serrations 5, together constitute a highly efficient and reliable stirring system. Applying this blade to a smoothie machine can significantly improve product quality and production efficiency, demonstrating significant practical value and market potential.
