Description

Technical Field

[0001] The invention relates to the field of mixing processing, in particular to a mixing stirrer. Background Art

[0002] A mixer is an electrical appliance used to mix materials and is widely used in food processing, beverage making, chemical mixing and other fields. A traditional mixer usually includes a fixed mixing cup and a motor-driven mixing head. Users put materials into the mixing cup and the motor drives the mixing head to mix, mix or crush them. However, existing mixers have some problems during use.

[0003] First of all, the traditional blending cup is usually fixedly connected to the machine base. When users pour out the blended materials, they often need to tilt the entire machine, which is inconvenient to operate and easily causes the materials to spill. To solve this problem, the blender is upgraded to a cup that can be detachably installed on the machine base, and the stirring head in the cup is connected to the motor in the machine base through a clutch. Since the cup body does not have the ability to supply electricity, the blender with a detachable cup body does not have a heating function. Even if a heating component is installed in the machine base, the combination of the heating component and the blending cup is not tight enough, resulting in low heating efficiency.

[0004] Secondly, since the detachable cup body is not fixed, it will vibrate and generate noise due to the high-speed rotation force of the stirring head.

[0005] In summary, the existing mixing mixers are in urgent need of a mixing mixer with a more compact structure, more convenient operation, higher heating efficiency and lower noise to meet the users' needs for efficient, convenient and silent mixing. Summary of the invention

The bottom of the installation cavity is provided with an opening groove adapted to the pressing block 232 and a rotating slot connected to the opening groove. The rotating slot is provided with a sliding groove adapted to the extension leg 231. The opening diameter of the sliding slot is smaller than the size of the pressing block 232, and only the extension leg 231 can slide. The pressing block 232 is inserted from the opening groove and rotated into the rotating slot. The pressing block 232 is pressed tightly in the rotating slot, so that the mixing cup assembly is pressed tightly in the installation cavity, reducing the noise caused by the shaking of the cup body 1 during mixing, and achieving silence.
