The invention provides a juice squeezer, and belongs to the technical field of juice squeezing. The juice squeezer comprises a frame body, an
actuator and a
capsule bag, wherein the
actuator also comprises a fixed piece, a movable piece, a driving rod, an acting block and a driver; according to the juice squeezer, a mounting surface is arranged in the frame body, and a surface which is opposite to the mounting surface is arranged as a fixed surface; the
actuator is arranged on the mounting surface; a propelling plate is arranged on one side, far away from the mounting surface, of the actuator; the actuator drives the propelling plate to perform reciprocating rectilinear movement along the mounting surface to the fixed surface, so as to extrude a food
raw material which is stored between the propelling plate and the fixed surface; therefore, the work of squeezing juice is finished, and the
noise is low; the juice squeezer is driven by a motor, and is provided with a speed changing device, so that the thrust of the actuator is greater, the squeezing is more thorough, and the efficiency is higher; by adopting the
coordinated movement of a screw and the acting block, the reciprocating property is high, and the working time is effectively prolonged; the
capsule bag is arranged between the actuator and the fixed surface, so that squeezed juice cannot be sputtered on components, and the purpose of avoiding cleaning is achieved.
