Energy-efficient electromagnetic micropump system

A micropump comprising:

• a head portion comprising a first movement guide and a second movement guide that are formed inside the head portion, the head portion comprising a first tip formed outside the head portion;
• and
• a body portion having at least a portion thereof accommodated in the head portion, the body portion comprising a core, a winding body surrounding the core, a first permanent magnet disposed at a lower end of a second side of the core, a second permanent magnet disposed at a lower end of a first side of the core, a first fixing guide disposed at an upper end of the second side of the core, and a second fixing guide disposed at an upper end of the first side of the core,
• wherein the first movement guide and the first fixing guide are formed such that the first movement guide and the first fixing guide correspond to each other, the second movement guide and the second fixing guide are formed such that the second movement guide and the second fixing guide correspond to each other,
• wherein the first permanent magnet is disposed such that a pole thereof faces or opposes a lower end contact surface of the core, and the second permanent magnet is disposed such that a facing direction of a pole thereof is same as a facing direction of the first permanent magnet, and
• wherein the head portion is configured to be moved to a first side thereof when electric current is applied to the winding body in a first direction, and the head portion is configured to be moved to a second side thereof when electric current is applied to the winding body in a second direction that is a direction opposite to the first direction.
