PumpingScrewBlender / Blender. Tumbler.


blender is a necessary thing for those who keep their health or when cooking and used in other various ways.

However, the existing blender couldn’t be used without electricity and was only limited to the use environment although it was highly utilizable. So I designed a screw mechanism so that blending could be possible only with pumping without electricity.

When you press it with your hand, the pressure is much more than you expected. You can induce a screw to rotate very fast.

Since this uses spring and buffer that support the forces of motion which are repeated when pumping, blending is possible by repetitive motion.
