A device (60) for achieving a controlled low emanation rate of small volumes of liquid solutions (37), such as single or multi-component solutions, fragrances, or pheromones, for pest and insect management or fragrance enhancement. The device (60) has a housing (61) with an upper chamber (97) to hold a bladder (62) containing desired liquid solution (37) to be released, a lower chamber (91) containing an electro-chemical gas generator (66), a collector pad (64) for receiving liquid solution (37) from the bladder (62), and a cap (65) which, when translated downward, activated the gas generator (66) which fills the upper chamber (97) with gas exerting pressure on the bladder (62) which in turn forces the liquid solution (37) from the bladder (62) onto the pad (64) for release to the environment. The gas generator (66) is capable of releasing gases such as hydrogen, oxygen, or carbon dioxide at extremely small, pre-determined, and adjustable rates.

L'invention concerne un dispositif (60) servant à réaliser un débit d'émanation faible et contrôlé de faibles volumes de solutions liquides (37), telles que des solutions, parfums ou phéromones à un seul ou à plusieurs composants, pour la lutte contre des animaux et insectes nuisibles ou le renforcement d'un parfum. Le dispositif (60) comprend un boîtier (61) comprenant une chambre supérieure (97) destinée à contenir une vessie (62) contenant la solution liquide souhaitée (37) à libérer, une chambre inférieure (91) contenant un générateur électrochimique de gaz (66), un tampon collecteur (64) servant à recevoir la solution liquide (37) provenant de la vessie (62) et un bouchon (65) qui, lorsqu'il est translaté vers le bas, active le générateur de gaz (66) qui remplit la chambre supérieure (97), le gaz exerçant alors une pression sur la vessie (62) qui à son tour force la solution liquide (37) à passer de la vessie (62) sur le tampon (64) pour la libérer dans l'environnement. Le générateur de gaz (66) est capable de libérer des gaz tels que de l'hydrogène, de l'oxygène ou du dioxyde de carbone à des débits extrêmement faibles, prédéterminés et ajustables.
