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.

Liquid infusion device equipped with a magnetic return-to-origin and fixation means

Provided is an electroosmotic pump including a housing including a shaft hole, a membrane disposed between a first space arranged in a direction away from the shaft hole and a second space adjacent to the shaft hole, a first electrode body and a second electrode body arranged at opposite sides based on the membrane, a shaft extending to an outside of the housing through the shaft hole, and a first fluid included in an internal space of the housing.
