Abstract

Disclosed in the invention is a portable food processor which comprises a container for containing food, a food processing component and a container cover component. The food processing component which is arranged inside the container can rotate relative to the container. The container cover component which is fixed to cover an opening of the container comprises a cover body, a driving component arranged in the top of the cover body and a transmission mechanism arranged in the cover body. The driving component drives the food processing component to rotate relative to the container through the transmission mechanism. The driving component is a pull rod component which comprises a chute arranged in the top of the cover body and a pull rod arranged in the chute. The pull rod is provided with a rack to mesh with a gear of the transmission mechanism. Since the pull rod component is used as the driving component in the present invention, only the pull rod needs to be pulled in a reciprocating manner when the portable food processor is operated. Compared with the operation mode of rotating a knob in the prior art, the portable food processor is more convenient and the transmission ratio during driving can be increased by providing a longer pull rod.
