Abstract
The present invention relates to a liquid infusion device composed of a combination of a reusable module, which can be used repeatedly, and a disposable module, which is replaced after use. The present invention includes a solenoid () that generates magnetic force when powered, a first movable body () equipped with a magnet that performs a reciprocating motion driven by the magnetic force of the solenoid, and a steel plate () configured to interact with the magnet of the first movable body through attractive force. The reciprocating first movable body moves between a first point, where it is closest to the solenoid, and a second point, where it is farthest from the solenoid. When the solenoid is not powered, the first movable body is fixed at either the first or second point due to the attractive force between the magnet and the steel plate.
