Breath-powered vapor distribution device
Device embodiments use a person's exhaled breath to distribute an evaporated, sublimated, or vaporized material. The disclosure provides non-powered devices that use evaporation or sublimation to create the vapor that is distributed and the disclosure provides devices with electric vaporizers which rapidly vaporize liquid scent materials for distribution. The scent can be designed as a masking or cover scent, an aromatic lure scent, a scent elimination material, a pleasant scent for freshening air in a room or automobile, or a repellant scent. The device can be worn as a mask. The device can be handheld or disposed at an area remote from the user's mouth with the breath blown in through a tube.
1. A scent material distribution device that uses a person's exhaled breath as an airflow that distributes the scent material from the device; the device comprising:
a body having an inlet and an outlet;
the body defining an airflow channel extending from the inlet to the outlet;
a power source;
a liquid scent material supply;
an electric burner that is selectively powered by the power source to rapidly vaporize a liquid scent material from the liquid scent material supply;
the electric burner being in fluid communication with the airflow channel at a first location such that vapor created by the burner can be distributed from the outlet;
a one-way valve;
the one-way valve being disposed along the airflow channel between the inlet and the first location; the one-way valve preventing vaporized scent material from the electric burner from being inhaled by the user through the inlet; the one-way valve allowing exhaled breath to flow from the inlet to the outlet; and
the first location being disposed along the airflow channel intermediate the one-way valve and the outlet such that exhaled breath passes through the one-way valve to move the vaporized scent material along the airflow channel to the outlet.
2. The device of claim 1 , wherein the body includes an elongated flexible inlet tube having an inlet end and an outlet end and defining a portion of the airflow channel.
3. The device of claim 2 , wherein the one-way valve is disposed at the outlet end of the flexible inlet tube.
4. The device of claim 2 , further comprising a filter disposed in the inlet tube.
5. The device of claim 1 , wherein the liquid scent material includes an animal lure aromatic material and at least one of a propylene glycol and a vegetable glycerin; the animal lure aromatic material including at least one of an animal urine material and a glandular secretion material.
6. The device of claim 1 , wherein the liquid scent material includes a scent elimination material and at least one of a propylene glycol and a vegetable glycerin.
7. The device of claim 1 , wherein the liquid scent material includes a hunting cover scent and at least one of a propylene glycol and a vegetable glycerin.
8. The device of claim 1 , wherein the liquid scent material supply is removable and replaceable.
9. The device of claim 1 , wherein the liquid scent material supply is refillable.
10. The device of claim 1 , further comprising a power switch activatable by the user to energize the electric burner.
11. The device of claim 1 , further comprising an airflow sensor in fluid communication with the airflow channel; the airflow sensor configured to energize the electric burner in response to airflow through the airflow channel.
12. A vapor distribution device comprising:
a power source;
a housing defining a fluid passageway having an outlet;
the housing including an inlet tube in fluid communication with the fluid passageway, the inlet tube adapted to receive exhaled breath from a user and direct the exhaled breath into the fluid passageway to generate a fluid flow;
a reservoir containing a vaporizable agent;
an electric vaporizing burner element in selective contact with the vaporizable agent;
a one-way valve preventing inhalation of the vaporizable agent; and
a switch being operable to selectively connect the power source to the electric vaporizing burner element, thereby energizing the electric vaporizing burner element to vaporize at least a portion of the vaporizable agent wherein the fluid flow carries the vapor into the atmosphere through the outlet as a vapor stream.
13. The device of claim 12 , further comprising an elongated flexible tube in fluid communication with the inlet tube of the housing; the elongated flexible tube adapted to deliver the exhaled breath to the inlet.
14. The device of claim 12 , wherein the vaporizable agent includes at least one of an animal lure aromatic material, a scent elimination material, and a hunting cover scent and at least one of a propylene glycol and a vegetable glycerin; the animal lure aromatic material including at least one of an animal urine material and a glandular secretion material.
15. The device of claim 12 , wherein the housing has a sidewall; the outlet being a plurality of openings in the sidewall.
16. The device of claim 12 , wherein the reservoir is removable and replaceable.
17. The device of claim 12 , wherein the reservoir is refillable.
18. A method of distributing a scent material with the user's exhaled breath comprising the steps of:
exhaling breath into a device through a one-way valve to provide an exhalation airflow;
vaporizing a liquid scent material with an electric burner to form a vaporized scent material;
mixing the vaporized scent material with the exhalation airflow only after the exhalation airflow has passed through the one-way valve such that the vaporized scent material cannot be inhaled from the device through the one-way valve; and
distributing the vaporized scent material from the device with the exhalation airflow.
19. The method of claim 18 , further comprising the step of directing the user's exhaled breath through an elongated inlet tube.
