Abstract
A nebulizer having an elongate housing supporting an air nozzle in aspirating relation to a liquid nozzle in an interior chamber of the housing to vaporize the liquid. Baffle discs each having a chordal section removed therefrom are placed in parallel spaced relation in the chamber substantially transverse to the direction of vapor flow in the chamber. The openings formed by the chordal sections of adjacent discs are non-aligned causing the vapor flow to follow a tortuous path, and impinge upon a baffle surface, collapsing larger liquid droplets in the vapor which collect in the chamber. A liquid flow control valve in one position connects the liquid nozzle to the accumulated liquid in the chamber, or to an external reservoir, and in a second position, to an exterior source of liquid.
Claims7
Nebulizer apparatus comprising;
- an elongate housing having a chamber therein and supporting a pneumatic nozzle in aspirating relation to a liquid nozzle in said chamber;
- a liquid inlet formed in said housing in fluid communication with said liquid nozzle;
- a pneumatic inlet formed in said housing in fluid communication with said pneumatic nozzle;
- a liquid passage between said chamber and said liquid nozzle;
- and
- flow control means for selectively connecting said liquid nozzle to one of said liquid inlet and liquid passage and comprising;
- a drum rotatably mounted at one end of said housing;
- said pneumatic inlet comprising a first axial passage;
- said drum having an eccentric axial passage parallel with said first axial passage and connected to a first transverse passage terminating in said liquid nozzle;
- said liquid inlet comprising a second transverse passage in fluid communication with said eccentric passage;
- and
- said liquid passage comprising a third transverse passage in fluid communication with said eccentric passage and angularly displaced from said second transverse passage.
A nebulizer according to claim 6 including means for connecting a liquid container to said housing in fluid communication with said liquid inlet.
