Abstract: An atomizer includes a main path having an entrance and an exit. At least two sources are connected to the entrance of the main path. A plurality of chambers communicate with the main path and a narrow path communicates with each chamber and the main path. A plurality of stops extend from an inner periphery of the main path and a distal end of each stop is located corresponding to the narrow path corresponding thereto. The chambers and the stops are located between the entrance and the exit. The two different fluids flow into the entrance and are disturbed by the stops and mixed in the chambers.
