The displacement of the magnet 71 at the end of the lifting column 51 is sensed The sensing signal is sent to the controller to detect whether the two bodies match or not match each other when the bottom body 10 and the middle body 20 are coupled to each other.

In the past, the open terminal used for sensing the displacement of the lifting column needs to be in contact with the lifting column (or the flange at the upper end of the lifting column), so that there is a problem that gas leaks through the contact path between the opening terminal and the lifting column. . In order to improve the problem, the sensing liquid-removing structure-improving connector of the cylindrical container of the present invention passes the bottom surface 721 of the insertion groove 72 so that the magnet 71 and the sensing member 73 do not contact each other to block The venting passage itself can solve the problem of gas leakage in the past.

Further, the storage liquid discharge connector of the cylindrical container of the present invention further includes a matching means 60, as shown in Figs. 1 to 3, the matching means 60 includes: a coding groove 61 at the bottom casing 11 of the bottom body 10. The upper portion is formed in a specific mode; and the coding protrusion 62 is formed corresponding to the code groove 61 at a lower portion of the middle casing 21 of the middle body 20.

At this time, the code groove 61 forms one or two or more circular or polygonal grooves, and the code protrusions 62 also form one or two or more circular or polygonal protrusions.

Therefore, as shown in FIG. 3, only when the coding groove 61 and the coding protrusion 62 are combined with each other in an uneven manner, the lifting column 51 of the lifting unit 50 is in contact with the upper periphery of the flow path 121 of the tube 12, and the lifting unit 50 The lifting column 51 rises and the magnet 71 is displaced.
