AN IMPROVED PORTABLE APPARATUS FOR GENERATING AND BROADCASTING AN AEROSOL MIST

摘要

A substantially closed rectangular chamber (1) equipped with a constant liquid level control device (19) has a cylindrical tube (2), open at one end (front) and closed at the other by a fan (5), mounted horizon¬ tally along-side an upper edge of the chamber. A piezoelectric transducer (10) located in the front quarter of the chamber base furthest from the cylinder generates an aerosol and a curtain (15) dropped from the top of the chamber by about a quarter its height restricts its movement, directly above the piezoelectric transducer. The chamber and cylinder are made contiguous by two conduits the first (3) of which leaves the chamber, at a right angle to its wall, above the liquid level and enters the cylindrical tube from below. The second conduit (4) is straight passes from the back of the upper chamber to penetrate the cylindrical tube at an acute angle to the cylinder and above a horizontal plane.
