A fluid delivery device including a fluid reservoir, a pump in fluid communication with the reservoir, an electric motor, a bladder in fluid communication with the pump, the bladder including at least in part, an elastic portion, a nozzle valve in fluid communication with the bladder, the nozzle being adjustable from an open mode to a closed mode, and from a closed mode to an open mode, a pressure release valve in fluid communication with the bladder and the fluid reservoir; and an electronic control unit for controlling delivery of the fluid. The invention also encompasses a method of delivering a treating fluid in a fine mist, including powering-up a fluid delivery device, comparing a signal being received from an ambient light sensor to predetermined trigger values consistent with dusk and dawn ambient light conditions, and dispensing treating fluid for a selected duration period on the basis of the signal being received from the ambient light sensor.

L'invention concerne un dispositif de distribution de fluide comprenant un réservoir de fluide, une pompe reliée fluidiquement au réservoir, un moteur électrique, une vessie reliée fluidiquement à la pompe, ladite vessie comprenant au moins partiellement une partie élastique, un obturateur de buse relié fluidiquement à la vessie, la buse pouvant se régler dans un mode ouvert et dans un mode fermé, et d'un mode fermé à un mode ouvert, un soupape de relâchement de la pression relié fluidiquement à la vessie et au réservoir de fluide; et une unité de commande électronique servant à réguler la distribution du fluide. L'invention concerne également un procédé de distribution d'un fluide de traitement sous la forme d'une brume fine, consistant à activer un dispositif de distribution de fluide, à comparer un signal reçu d'un capteur de lumière ambiante avec des valeurs de déclenchement prédéterminées correspondant à des conditions de lumière ambiante crépusculaire et à diffuser le fluide de traitement sur une période sélectionnée en fonction du signal reçu du capteur de lumière ambiante.
