1. A fluid inhalation device, comprising:
a casing having therein
a fluid reservoir, having
a top end and
a bottom end,
a fluid-air outlet connected to the top end of the fluid reservoir,
a nozzle, having
a nozzle exit connected to the fluid reservoir, and
a nozzle throat,
a vacuum channel, having
a bottom end connected to the bottom end of the fluid reservoir, and
a top end connected to the nozzle,
an air duct, having
an air inlet at a first air duct end, and
a second air duct end connected to the nozzle throat, and
a mouth piece, containing the fluid-air outlet,
wherein the nozzle throat is narrower than the nozzle exit, and
when fluid is present in the fluid reservoir, the fluid inhalation device delivers 0.001 to 0.01 ml of fluid under suction pressure through the mouth piece without heating and solely powered by mouth of a human user of −0.14 to −0.36 PSI, negative pressure relative to atmospheric pressure, in 1 second, and the suction pressure causes air to enter the air inlet and a fluid-air mixture to exit through the fluid-air outlet.
