<p><P>PROBLEM TO BE SOLVED: To provide a liquid sucking device for perfectly stopping the suction of a liquid without sucking air when the residual amount in a liquid container becomes a predetermined amount or below. <P>SOLUTION: The liquid sucking device is equipped with the leading end member inserted in a container through the opening provided to the container to be immersed in a liquid, the liquid storage chamber provided to the leading end member and having an inflow port and a discharge port, the suction pipe connected to the leading end member to extend from the opening of the container and the float member provided to the discharge port to open and close the discharge port. When the leading end member is immersed in the liquid, the liquid is stored in the storage chamber and a float member is floated to open the discharge port. The liquid in the container is sucked to the outside through the inflow port, the storage chamber and the suction pipe. When the liquid in the container is reduced to become a predetermined amount or less, the stored liquid is dischargved from the inflow port to close the discharge port by the float member. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
