Abstract: A device (30) for nebulizing a liquid includes a nebulization head (40) having a capillary tube (40-1) and a nozzle (40-2) for ejecting a liquid (43), a liquid supply tank (42) for supplying the nebulization head with liquid (43), a vibrator (44) for vibration driving the nebulization head so that it ejects droplets of liquid in a nebulization jet. The device (30) further includes a pressure regulator for applying to the liquid at the inlet to the nebulization head (40), during nebulization cycles, a pressure greater than a first pressure threshold above which the liquid flows through the nebulization head when the head is not vibration driven, and lower than a second pressure threshold above which the liquid flows through the nebulization head when the head is vibration driven. Advantages of the device include increase in the nebulization flow rate and low sensitivity to changes in trim and to vibrations.

Abstract: A control method for one or several devices for nebulizing liquids into the air (DF1), the method including control steps for the device to nebulize a liquid into the air according to nebulizing cycles during which a liquid is nebulized into the air, the nebulizing cycles being spaced by idle periods, and comprising adjustment of the duration of idle periods as a function of the average quantity of liquid to be nebulized per unit time selected, and as a function of a concentration parameter for the active product in the liquid to be nebulized. The method enables a same apparatus to treat volumes with a factor of 100 times, typically from 7 to 700 m3.
