Abstract

The invention relates to a nebulisation device, comprising a liquid reservoir (100), a liquid supply line (121) for supply of liquid to a nebulisation zone (130) and an outlet opening (190) from the nebulisation zone by means of which a flow of nebulised liquid particles escapes the nebulisation zone. According to the invention, the outlet opening (190) opens into the liquid reservoir (100) above the level of the liquid and the liquid reservoir has an escape opening (195) for nebulised liquid particles, by means of which some of the nebulised liquid particles, coming from the outlet opening, leave the reservoir (100). Optionally, the device comprises an outside air inlet duct (140) with a nozzle (115) in the nebulisation zone and an opening to outside air (141) in the liquid reservoir.
