MICRO FLUID SPRAYER FOR SPRAYING AT LEAST TWO KINDS OF FLUIDS AND METHOD THEREFOR

摘要

PURPOSE: A micro fluid sprayer and a method for spraying at least two kinds of fluids are provided to selectively use fluids by generating expansion pressure through expanding one fluid and spraying the other fluid by using the expansion pressure. CONSTITUTION: A micro fluid sprayer includes a horizontal fluid path(20). The front portion of the horizontal fluid path(20) is opened. Expansion fluid stored in an expansion fluid storing section is supplied into the horizontal fluid path(20). At least one spraying fluid feeding path(30) is provided. The spraying fluid feeding path(30) is communicated with the front portion of the horizontal fluid path(20). Spraying fluid is supplied into the spraying fluid feeding path(30) from a spraying fluid storing section. A heating section(40) is installed in the horizontal fluid path(20). Expansion fluid supplied from a rear end of the horizontal fluid path(20) stays in a predetermined portion, at which the horizontal fluid path(20) is communicated with the spraying fluid feeding path(30), thereby forming an interfacial surface with respect to spraying fluid.
