摘要：
A spray device for generating a slow moving aerosol, whereby the aerosol is generated from at least two impinging jets and the jets are formed by forcing liquid through a single moulded plastic nozzle assembly comprising: a. one or more thin walled sections (typically <200 μm) (18) where the thin wall sections (18) are supported by one or more thick walled sections (typically >200 μm) (17, 19). b. at least two opposing holes (13) with hydraulic diameters of 5 pm to 100 μm (typically 30 μm) and axes at an angle of between 55 and 125 degrees (preferably 90 degrees) to an external surface of the thin walled section (18), such that the projected areas of the holes (13) at least partially intersect at the outlet side of the nozzle.
