An upper float ball is set in the jar mouth shrunk at the bottom, and a bottom float ball is set outside of the jar mouth. Two float balls are joined together by an inner bulgy circle of the fixing coat, and the fixing coat connects with the jar mouth. The two float balls with opposite awl-shape necks are wedged to the aperture formed by inner bulgy circle. The two float balls can be adjusted clearance. When the upper float ball is moved up, the liquid in the jar will flow out gradually. As the upper float ball is moved down, the aperture will be closed. A heavy article is connected with the bottom float ball to accelerate pulling down. Furthermore, a fixed position cup is hooked on the jar, and the bottom of the fixed position cup has a perforated colander.
