Ultrasonic wave nebulizer

An ultrasonic wave nebulizer for pumping and atomizing water comprising;

• an elongated main body having an axis, a center through hole, a water inlet at once end and amist outlet at the other end,
• said main body having male screw means at an external wall around a central portion of the main body,
• a plurality of disc shaped vibration elements together with electrodes for energizing the vibration elements, each having a center hole for accepting said main body, so that vibration energy is transmitted in both directions of said main body,
• nut means with female screw means for fixing said vibration elements together with electrodes on said main body by engaging the female screw means with the male screw means on said main body,
• a first water proof means fixed to said main body for covering said vibration elements and said electrodes, and having a flange for fixing the nebulizer to an external structure,
• said flange extending in a plane perpendicular to the axis of the main body and being defined by a center of the vibration elements along the axis,
• a second water proof means for preventing water to said vibration elements through a passage between said nut means and said main body,
• said first water proof means being made of resilient plastics covering said vibration elements and said electrodes in non-contacting relation.
