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.
Claims17
A mist generator comprising:
- a housing;
- a mist rotor within the housing and having at least one mist hole, rotatably supported substantially within a mist chamber;
- means for rotating the mist rotor, supported by the housing;
- a bowl in the mist chamber for supplying a fluid medium to the mist rotor;
- and
- a bowl supply port in the bowl for supplying a mist medium.
A device for generating a spray of fine surface-wetting droplets of a liquid comprising:
- a nebulizing module including:
- a nebulizing module housing;
- a motor within the nebulizing module housing, the motor including a shaft;
- a rotor mounted on the shaft and supported in a mist chamber;
- a mist port extending through the nebulizing module housing into the mist chamber;
- a directional light source within the nebulizing module housing for targeting the spray;
- a switch means for actuating the motor and directional light source;
- attachment means on the nebulizing module housing for attaching it to another module;
- a pump and cartridge composite module attached to the nebulizing module by said attachment means and including:
- a composite module housing;
- a cartridge for holding a liquid within the composite module housing;
- and
- a finger actuated pump within the composite module housing for pumping the liquid from the cartridge to the mist chamber in the nebulizing module.
A device for generating a spray of fine surface-wetting droplets of a liquid comprising:
- a nebulizing module including:
- a nebulizing module housing;
- a motor, within the nebulizing module housing, the motor having a shaft;
- a rotor mounted on the shaft and supported in a mist chamber;
- a mist port extending through the nebulizing module housing into the mist chamber;
- a switch on the device for actuating the motor;
- a pump module attached to the nebulizing module housing;
- a cartridge module attached to the pump module, for containing the liquid;
- and
- a pump in the pump module for pumping the liquid from the cartridge module into the mist chamber of the nebulizing module.
