Abstract
A micro-pump for atomizing and including a main-housing, a nozzle plate, at least an actuator, and a liquid transport pipe is provided. The main-housing has a liquid inlet, a liquid outlet, an air inlet, and a micro-droplet outlet. The nozzle plate is assembled to the main-housing and has at least one nozzle. The nozzle plate divides the interior of the main-housing into a first chamber and a second chamber. The nozzle and the liquid inlet are connected with the first chamber. The air inlet, the liquid outlet, and the micro-droplet outlet are connected with the second chamber. The actuator is disposed on at least one of the main-housing or the nozzle plate. The actuator drives the nozzle plate, so that liquid is filled into the first chamber and sprayed out through the nozzle into the second chamber. The liquid transport pipe connects the liquid inlet and the liquid outlet.
