    • PURPOSE: To reduce the danger of forming a sticking matter upon an aerosol by the constitution that a case is provided with an air intake port and the air intake port is connected to the front chamber of an ultrasonic wave atomizer. CONSTITUTION: A sieve plate or a partition wall 22 having the plurality of a small and round holes are provided just adjacent to an ultrasonic wave atomizer. The partition wall 22 is formed as an almost half circle, and provides a comparatively larger hole 24, and the atomizing surface of an atomizing plate 10 is inserted into the hole 24. Accordingly an almost ring-shaped separated aperture is made between the atomizing plate 10 and the circumferential edge of the hole 24. The partition wall 22 has two functions. The one is to be useful for mechanically protecting the damage of an atomizer 8 and the atomizing plate 10, the other one is to send a laminar air flow through a numberless small holes into a chamber 26 where is in the upper, and which can be called as an aerosol chamber. When an air is sucked through an air intake port 28 composed as a slit having a slit end 28a, 28b connected to an aerosol chamber 26, the laminar air flow is generated at once. Accordingly, the partition wall 22 can be deemed as the laminar flow-making means of an air sucked. The air intake port 28 is arranged at the right below of the partition wall 22.
