Abstract
A device for generating a spray of mist or fine droplets includes a spinning rotor within a mist chamber. The rotor has inner walls which taper conically outwardly from the open bottom of the rotor to a hole near the top of the rotor. Liquid is pumped by a finger actuated pump from a cartridge module into a bowl surrounding the bottom end of the rotor. A spray is created as the liquid is formed into droplets as it passes through the hole in the rotor under centrifugal force. A directional light source is used for aiming the spray.
Claims27
A mist generator comprising:
- a housing;
- a mist rotor in the housing having at least one mist hole, rotatably supported substantially within a mist chamber;
- a motor linked to the mist rotor;
- a pump adjustable to deliver a varying volume of fluid with each actuation of the pump attached to the housing, and separate from the mist rotor for supplying a fluid medium to the mist rotor.

A method of spraying a fluid mist comprising the steps of:
- pumping fluid with a finger actuated pump to deliver a fluid to a mist chamber;
- spinning a mist rotor having a mist hole within the mist chamber, thereby causing the fluid to be drawn up into the mist rotor;
- forming fine mist fluid droplets within the mist chamber by passing fluid through the mist hole in the mist rotor under centrifugal force;
- and
- directing the mist of fluid droplets in the direction of an area to be sprayed.
