Claims (1)

[Scope of Claim for Utility Model Registration] 1. A sealed plastic container that has an infusion intake tube for connecting to an infusion bottle at the upper end and a socket for inserting an infusion outlet tube at the lower end; a floating cylinder that is placed and receives buoyancy from the infusion flowing into the container; an annular magnet fixed to the lower end of the floating cylinder; a magnetically actuated contactor, the magnetically actuated contactor comprising two symmetrical contactor halves which are rotatably coupled to each other at one end, each having a A half-hole for fastening is provided in a semi-cylindrical shape, and there are two upper and lower gaps in each half, a semicircular magnet is arranged in the upper gap, a movable piece is arranged in the lower gap, These semicircular magnets and the movable piece are connected by a rod-shaped core, and a movable contact is formed on each of the movable pieces, and a corresponding fixed contact is provided, and the fixed and movable contacts are arranged around the rod-shaped core. A coil spring is arranged to release the infusion tube, and while the infusion in the sealed container is above a certain level, the infusion flows into the infusion take-out tube, but when the infusion drops below the above level, the lower end of the floating cylinder is An annular magnet approaches each of the semicircular magnets on the upper part of the magnetically actuated contactor, and both magnets are attracted to each other to prevent the infusion from flowing into the infusion extraction tube, and the fixed and movable magnets are moved against the elastic force of the coil spring. An automatic drip drip alarm device that generates an alarm by bringing contacts into contact and activating an alarm circuit. 2. The apparatus according to claim 1, wherein the annular magnet at the lower end of the floating cylinder and the semicircular magnet at the upper part of the magnetically actuated contactor have opposite polarities. 3. The device according to claim 1, wherein the take-out portion inside the bottom end of the closed container and the lower end of the floating cylinder are both formed in a conical shape, and firmly shut off the infusion when most of the infusion is used up.
