Publication number: 20180070755Abstract: A juicer comprises a frame, an actuator, and a juicing bag. The actuator comprises a propulsion plate, stationary parts, moving parts, a driving rod, action blocks and a driver. The frame includes a mounting plate and a front fixed plate facing the mounting plate. The actuator is attached on the mounting plate and the propulsion plate is attached on the actuator and distant from the mounting plate. The juicing bag encloses food and can be placed between the actuator and the fixed surface. The propulsion plate reciprocates linearly between the mounting plate and the front fixed plate to squeeze the food in the juicing bag, thereby juicing with small noise. Because food is enclosed in the juicing bag during juicing, juice does not sputter onto the juicer. Thus, the juicer does not require cleaning.Type: ApplicationFiled: July 21, 2017Publication date: March 15, 2018Inventors: Xiuxing Chen, Yitong Liu, Zechen Yang
