a fruit juice machine

Abstract

The invention relates to a juicer, comprising a machine body and a cup body, wherein the machine body is internally provided with a motor and a lower shaft coupling piece connected with a motor power output shaft; the cup body is provided with an agitating tool base in a penetrating manner; the agitating tool base is provided with a rotary shaft; the upper end of the rotary shaft is connected with a tool and the lower end of the rotary shaft is connected with an upper shaft coupling piece matched with the lower shaft coupling piece; a plurality of arc-shaped grooves are formed in the lower end face of the upper shaft coupling piece; a plurality of elastic convex parts adapted to the arc-shaped grooves are arranged on the lower shaft coupling piece; parts of the elastic convex parts are embedded into the arc-shaped grooves to drive the tool to rotate normally under the driving of the motor; when the tool encounters the phenomenon of being stuck, the upper shaft coupling piece cannot rotate; the lower shaft coupling piece is forcedly driven by the motor and the elastic convex parts slide in the plane of the arc-shaped grooves; and the lower shaft coupling piece continues to rotate and the problem that the tool is burnt up due to the fact the motor cannot rotate since the tool is stuck is avoided.

Description

technical field [0001] The invention relates to a fruit juice machine, in particular to a fruit juice machine safety mechanism for preventing the motor of the fruit juice machine from being overloaded. Background technique [0002] With the rapid development of the economy and the accelerated pace of life, people have less and less time to participate in sports, and the amount of exercise is seriously insufficient. More and more people tend to be obese. Obesity can easily lead to various diseases. Under the guidance of good health, organic fruits and vegetables have become a good food in people's healthy life, and squeezing fruits and vegetables through a juice machine is not only more convenient to eat, but also improves the taste. [0003] In the process of juicing, the motor of the juice machine provides power to drive the cutter to rotate at a high speed to cut vegetables and fruits to achieve the purpose of juicing. The cutter is installed on the stirring tool seat,...
