AI Technical Summary
The single-layer blade design of existing food blenders results in the blades bearing a large load, wearing out quickly, and having poor cutting and blending efficiency.
It employs two blade designs: the first blade is a straight blade, and the second blade is a curved blade. The curved blade is close to the bottom of the container for cutting and stirring, while the straight blade restricts the liquid from rising, increasing the stirring area and efficiency.
In this way, the curved blade design enhances the efficiency of food cutting and mixing, improving the effectiveness and efficiency of food processing.
