Abstract
A method and apparatus comprising a headgear that has a channel conduit implemented therein, preferably on a brim of the headgear. The channel conduit is operatively connected to a liquid source via a conduit. The liquid source holds a liquid, such as water. A liquid pumping means in the liquid source pushes the liquid, under pressure, through the conduit, into the channel conduit. Tiny openings in the channel conduit expel the liquid in the form of minute droplets, which readily evaporate because of their tiny size. Their evaporation produces a cooling effect in an area around the channel conduit, such as around the facial area of a user wearing the apparatus.
Claims13
A cooling device, comprising:
- a headgear configured to fit on a head of a user, said headgear comprising a brim and a channel implemented in said brim;
- a first conduit implemented in said channel, said first conduit comprising a plurality of openings at a bottom side of said brim, wherein said first conduit is implemented in a circular pattern extending around a periphery of a central portion of said headgear and said plurality of openings are equally distanced from said periphery of the central portion;
- and
- a liquid source operatively connected to said first conduit, said liquid source comprising:
- a cavity in said liquid source, said cavity able to hold a volume of liquid, and
- a pump for pumping said liquid in said cavity to said first conduit;
- wherein said plurality of openings are configured to expel said liquid as minute droplets of the liquid around a facial area of said user.
A method of personal cooling, comprising:
- accommodating a headgear on a head of a user, said headgear comprising a brim and a channel implemented in said brim;
- implementing a first conduit in said channel in a circular pattern extending around a periphery of a central portion of said headgear, said first conduit comprising a plurality of openings at a bottom side of said brim;
- operatively connecting a liquid source to said first conduit, said liquid source comprising:
- a cavity, said cavity operable to hold a volume of liquid, and
- a pump for pumping said liquid in said cavity;
- and
- expelling said liquid from said first conduit as minute droplets of said liquid, wherein said plurality of openings are equally distanced from said periphery of the central portion and said liquid is expelled through said openings around a facial area of said user.
A portable personal cooling device, comprising:
- a headgear, said headgear wearable on a head of a user;
- a brim on said headgear;
- a first conduit implemented in said brim in a circular pattern extending around a periphery of a central portion of said headgear;
- a second conduit having a first end and a second end, wherein the first end of said second conduit is operatively connected to said first conduit in a substantially watertight manner;
- a liquid source, wherein said liquid source is operatively connected to the second end of said second conduit in a substantially watertight manner;
- a cavity in said liquid source, wherein:
- said cavity is operable to hold and carry a liquid, and
- said second end of the second conduit has access to the liquid in said cavity;
- a pump in said liquid source, wherein
- said pump is operable to pump the liquid in said cavity under pressure through said second conduit to said first conduit;
- and
- said pump is either a mechanical pump or an electrical pump;
- and
- a plurality of openings defined in said first conduit and located at a bottom side of said brim, said plurality openings equally distanced from said periphery of the central portion,
- wherein said plurality of openings are configured to expel said liquid as minute droplets of the liquid around a facial area of said user.
