Abstract
Description
Technical Field
[0001] This utility model relates to the field of food processing machines, specifically to a stirring device. Background Technology
[0002] Food processors commonly found on the market typically employ a combination of fixed and moving blades to pulverize food. However, a common problem in their operation is that the fixed and moving blades are usually positioned facing each other. This design leads to low synergy between the two blades during processing, thus affecting the overall pulverizing effect. Specifically, the gap between the moving and fixed blades cannot remain uniform during high-speed rotation, resulting in uneven stress on the food during processing. Some ingredients may not be fully cut by the blades, leaving behind particles of varying sizes. This not only reduces the uniformity of food processing but also affects the texture and quality of the final product, especially noticeable when making fruit purees, meat fillings, and other foods requiring a fine texture.
[0003] This design also leads to problems with the stability and durability of the equipment. Due to the mismatch in position between the two cutter discs, the imbalance during rotation can easily cause localized collisions or increased friction, accelerating wear of the cutter discs over long-term use and potentially causing blade deformation or damage. This not only increases maintenance costs for users but also shortens the overall lifespan of the mixing device to some extent, reducing its practicality and economic efficiency. Utility Model Content
[0004] The purpose of this invention is to provide a stirring device in which the fixed blade is mounted on the blade holder.
[0005] This is how the objective was achieved.
[0006] A stirring device includes stirring blades and a stirring cup. The stirring blades are disposed inside the stirring cup. The stirring blades include a movable blade disc, a fixed blade disc, a rotating shaft, and a blade holder. The blade holder is located at the bottom of the stirring cup. The movable blade disc is drivenly connected to the rotating shaft, which is rotatably mounted on the blade holder. The fixed blade disc is fixedly mounted on the blade holder. The fixed blade disc is installed close to the center of the cup. When the movable blade disc rotates, the movable blade disc does not contact the fixed blade disc.
[0007] This utility model can also be optimized in the following ways.
[0008] Preferably, the moving blade disc is provided with a first blade section, a second blade section, a third blade section and a fourth blade section in sequence. The first blade section extends horizontally upward from the blade holder and has a vertically downward turning part. The other end of the first blade section extends horizontally to form the second blade section. The other end of the second blade section extends vertically downward to form the third blade section. The other end of the third blade section extends to form the fourth blade section that fits the shape of the bottom surface of the mixing cup. The second blade section, the third blade section and the fourth blade section together form a clearance space.
[0009] Furthermore, the fixed tool disc is disposed within the clearance space.
[0010] With this structural design, when the moving cutter head rotates at high speed driven by the rotating shaft, the fixed cutter head is positioned within a clearance space. This prevents contact and collision between the moving and fixed cutter heads, effectively avoiding problems such as localized collisions and increased friction caused by mismatched positions. This significantly reduces cutter head wear and the possibility of blade deformation or damage. This not only lowers user maintenance costs but also significantly extends the overall service life of the mixing device, improving its practicality and economy. Furthermore, the unique blade design of the moving cutter head and its optimal positional relationship with the fixed cutter head enable the mixing device to operate more stably and efficiently during the mixing process, enhancing the mixing effect.
[0011] Preferably, the fixed blade includes a support portion and a cutting portion, the support portion connects the cutting portion and the blade holder, and the cutting portion extends horizontally from one end of the support portion in a direction away from the blade holder.
[0012] The support structure provides a stable foundation for the fixed blade, ensuring the cutting section maintains a stable posture during mixing and preventing displacement or shaking due to material impact or mixing forces. The horizontally extended cutting section increases the cutting area, allowing the fixed blade to better contact the material during mixing and improving cutting efficiency. This design also enables the fixed blade to generate shearing force during mixing, working in conjunction with the moving blade disc to further enhance the mixing effect. Furthermore, the connection between the fixed blade and the blade holder is carefully designed to ensure the stability and reliability of the fixed blade during mixing.
[0013] Preferably, the stirring cup has equidistant protruding ribs on its wall.
[0014] These protruding ribs are evenly distributed along the circumference of the mixing cup wall, serving multiple functions during the mixing process. Firstly, the ribs alter the flow trajectory of the material within the mixing cup, generating more turbulence and collisions, resulting in more uniform mixing and improved mixing efficiency. Secondly, the ribs enhance the structural strength of the mixing cup wall, making it more stable against the impact forces of the material during mixing, less prone to deformation or damage, and extending the lifespan of the mixing cup. Furthermore, this design reduces material adhesion to the cup wall during mixing, facilitating subsequent cleaning.
[0015] By adopting the above technical solution, this utility model effectively avoids direct collisions and wear between the fixed and moving blades by placing the fixed blade on the blade holder and positioning it close to the center of the cup, while ensuring that the moving blade does not contact the fixed blade during rotation. This design improves the service life and stability of the stirring device. The first, second, third, and fourth blades sequentially arranged on the moving blade, along with the clearance space they form, further optimize the stirring effect, allowing the material to be cut and mixed more evenly during the stirring process. The fixed blade, positioned within the clearance space, further ensures smooth stirring. In addition, the equidistantly spaced protruding ribs on the wall of the stirring cup increase friction during stirring, resulting in more thorough stirring and improved stirring efficiency.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0022] Combination Figures 1 to 3A stirring device includes stirring blades and a stirring cup 1. The inner side of the stirring cup 1 has a number of protruding ribs evenly distributed along the circumferential direction. These protruding ribs help to form turbulence during the stirring process and improve the mixing uniformity of the materials.
[0023] Combination Figure 2 The stirring blade is integrally disposed inside the stirring cup 1, and its structure includes a moving blade disc 4, a fixed blade disc 5, a rotating shaft 3, and a blade holder 2, wherein the blade holder 2 is fixedly installed at the bottom center position of the stirring cup 1. The moving blade disc 4 is driven by the rotating shaft 3, and the rotating shaft 3 itself is rotatably supported on the blade holder 2.
[0024] Combination Figure 3 The moving blade disc 4 is provided with a first blade section 41, a second blade section 42, a third blade section 43, and a fourth blade section 44 arranged sequentially from top to bottom. The first blade section 41 extends horizontally upward from the blade holder 2 for a certain distance and then forms a vertical turning section 40 downward. Its other end continues to extend horizontally to form the second blade section 42. The end of the second blade section 42 bends downward to form the vertically downward third blade section 43. The third blade section 43 further extends into the fourth blade section 44, which matches the curved surface shape of the bottom of the mixing cup 1. The second blade section 42, the third blade section 43, and the fourth blade section 44 together form a clearance space. The fixed blade disc 5 is fixedly installed on the blade holder 2, and its entire body is located inside the aforementioned clearance space.
[0025] Combination Figure 3 The fixed blade disc 5 specifically includes a support part 51 and a cutting part 52. One end of the support part 51 is connected to the blade holder 2, and the other end extends horizontally outward to form the cutting part 52, which is arranged in a direction away from the blade holder 2. The support part 51 of the fixed blade disc 5 is installed close to the center area of the cup body. When the moving blade disc 4 rotates around its axis, its blades maintain a non-contact relationship with the fixed blade disc 5, achieving efficient and safe stirring action.
[0026] Combination Figure 4 In another embodiment, the fixed cutter head may be provided with two cutter heads facing each other.
