Abstract
An aerosol aspirator has a casing (2) with a mouthpiece (8) and an outside air inlet (52), a generation passage (56, 60, 68) extending from the outside air inlet (52) to the mouthpiece (8), a syringe pump (18) arranged within the casing (2) to deliver a solution to a distributing position (A) in the generation passage in a fixed amount each time it is activated, and a tubular heater (58) disposed downstream of the distributing position (A) and forming a part of the generation passage. When a user sucks at the mouthpiece (8), the solution at the distributing position (A) is transferred from the position (A) into the heater (58), and within the heater, atomized, and then turns into an aerosol by condensing in sucked air flow, and the aerosol thus formed is sucked by the user with the air flow.
