  • Personal cooling device
    Patent number: 12178273
    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.
