A nebulizer and a nozzle thereof are provided. The nozzle has a containing seat and a cover. The containing seat has an air conduit. The air conduit has an input terminal and an output terminal. The cover has a guiding channel and an impediment. An input opening is formed in the nozzle for introducing air. A first opening of the guiding channel is disposed near the output terminal and the input opening is disposed far of the output terminal. The impediment is disposed in front of the output terminal and has a plane. Air emitted from the output terminal lashes the plane and then flows to a second opening of the guiding channel, and the air of the input opening is guided to the first opening for decreasing a whole resistance of the nozzle, and thereby increasing nebulization efficiency.

An atomizer includes a motor mounted in a housing. First and second cylinder units are received in the housing. The first cylinder unit includes a first piston and a first coupling bearing connected to the first piston. The second cylinder unit includes a second piston and a second coupling bearing connected to the second piston. An eccentric transmission shaft of the motor extends through the first and second coupling bearings of the first and second cylinder units. The first and second pistons of the first and second cylinder units move reciprocatingly when the motor operates. An intake check valve is mounted in an intake passage between an intake port of the first cylinder unit and an inlet of the housing. An outlet check valve is mounted in an outlet passage between an outlet port of the second cylinder unit and an outlet of the housing.
