A CONTINUOUS EJECTOR WITH A PARALLEL THERMO-PNEUMATIC PUMP

摘要

PURPOSE: A continuous ejector equipped with a parallel-connected thermo pneumatic pump is provided to successively jet fluid by making two or more parallel-connected thermo pneumatic pumps have opposite periodicity. CONSTITUTION: A continuous ejector of fluid comprises a first thermo pneumatic pump(210), a second thermo pneumatic pump(220), an ejector(230), and a controller(240). The first thermo pneumatic pump includes a thin film(215). The second thermo pneumatic pump includes the thin film(225) and is connected with the first thermo pneumatic pump in parallel. The ejector inhales the fluid which is exhausted from the first thermo pneumatic pump and the second thermo pneumatic pump by turns and sprays the fluid. The controller creates a first control signal and a second controlling signal. The first control signal controls operation of the first thermo pneumatic pump. The second controlling signal controls the operation of the second thermo pneumatic pump.
