1. A spraying device comprising:
- a tank that has an opening at an upper part thereof, the tank being configured to contain a liquid to be sprayed while being filled up to the opening and wherein the cross-section of the tank has a progressive constriction toward the opening;
a piezoelectric element configured to emit waves into the liquid, the waves being focused adjacent the opening of the tank;
a fan configured to circulate air in the vicinity of the surface of the liquid;
a collection container in which the tank is located;
a pump connected to the collection container and to the tank and configured to circulate liquid continuously between the tank from which the liquid overspills and the collection container where the liquid is collected; and
a liquid reservoir connected to the pump for keeping a quantity of liquid circulating in the spraying device substantially constant.

Abstract
The invention relates to a spraying device including a tank which is open at its upper part, capable of containing a liquid to be sprayed, such as water, while being filled up to its opening, a piozoelectric element capable of emitting waves into the liquid and fan means for creating a circulation of air in the vicinity of the surface of the liquid. The waves are focused in the vicinity of the opening of the tank, and the cross-section of the tank (1) has a progressive constriction towards the opening (2) of the tank (1).
