Abstract:

An electronically controlled micro-dispensing apparatus ( ) is described. The apparatus includes a container ( ), an adaptor ( ), a nozzle ( ) and a control circuit ( or ). The container is filled with the chemical ( ) and propellant ( ). The adaptor, nozzle and control circuit are removable from the container and are reusable. The control circuits controls the length of pulse and the time duration between each pulse. By controlling these factors, the apparatus dispenses a precise amount of liquid over a set time period.

Abstract:

An electronically controlled micro-dispensing apparatus (10) is described. The apparatus includes a container (12), an adaptor (18), a nozzle (28) and a control circuit (34 or 42). The container is filled with the chemical (104) and propellant (102). The adaptor, nozzle and control circuit are removable from the container and are reusable. The control circuits controls the length of pulse and the time duration between each pulse. By controlling these factors, the apparatus dispenses a precise amount of liquid over a set time period. The ejector allows for controlled dispensing and allows the liquid to be sprayed a greater distance. In the preferred embodiment, the apparatus are used to dispense a pheromone in an outdoor setting, such as an orchard (100), to control insects.
