20160127817, May 5, 2016

Filed:

Oct 30, 2015

Appl. No.:

14/927463

Inventors:

Gregory Michael MacDonald - Alameda CA, US

International Classification:

H04R 1/10

Abstract:

The present invention provides a device for removing sweat from the inner ear by creating a vacuum in connecting tubing between the inner ear and a converging-diverging nozzle. When air enters the front of the converging-diverging nozzle, its velocity accelerates as it flows through the smaller cross-sectional area in the middle section, which causes a drop in pressure in the middle section and a resulting vacuum in the connecting tubing. This vacuum draws sweat from the bottom of the inner ear toward the middle of the converging-diverging nozzle, where it drips out of either end, resulting in sweat being removed from the inner ear.

Abstract:

The present embodiment provides a straw that is bent near its middle portion to form a reservoir compartment to store a liquid for cooling. When a user sips from the straw, hot liquid from a container enters the reservoir compartment, where it begins to cool towards the surrounding air temperature. When the liquid in the reservoir compartment reaches an acceptable drinking temperature, the user again sips from the straw, which allows him to drink the cooled liquid from the reservoir compartment, and to draw additional hot liquid from the container into the reservoir compartment for cooling.
