Abstract

A vaporization device including a housing, a plurality of wicks, a plurality of heating elements and a power control circuit. The plurality of wicks are at least partially contained within the housing and include a first wick and a second wick. The plurality of heating elements include a first heating element and a second heating element. The first heating element is proximate to the first wick and the second heating element is proximate to the second wick. The power control circuit powers the first heating element at a first level when the second heating element is not powered. The power control circuit powers the first heating element at a second level when the second heating element is powered.

Claims (20)

1. A vaporization device, comprising:

a housing;

a plurality of wicks at least partially contained within said housing including a first wick and a second wick;

a plurality of heating elements including a first heating element and a second heating element, said first heating element proximate to said first wick, said second heating element proximate to said second wick, said plurality of heating elements being in an electrically parallel relationship; and

a power control circuit powering said first heating element at a first average power level when said second heating element is substantially not powered, said power control circuit powering said first heating element at a second average power level when said second heating element is powered.

2. The vaporization device of claim 1 , wherein said first average power level and said second average power level are average power levels determined over at least one second.

3. The vaporization device of claim 1 , wherein said second heating element is powered at substantially said second average power level when said first heating element is powered at said second average power level, said first average power level being greater than said second average power level.

4. The vaporization device of claim 3 , further comprising a selector controllably connected to said power control circuit, said selector setting determining whether said first heating element and said second heating element are powered.

5. The vaporization device of claim 4 , wherein said selector selects one of a plurality of modes including a heating of said first wick mode, a heating of said second wick mode and a heating of both said first wick and said second wick mode.

6. The vaporization device of claim 5 , wherein said heating of said first wick mode and said heating of said second wick mode respectively causes said first average power level of heating to occur in said first heating element and said first average power level of heating to occur in said second heating element.

7. The vaporization device of claim 6 , wherein said second wick receives some heat from said first heating element when said first heating element is powered.

8. A method controlling the vaporization rates of a multi-wick device, comprising the steps of:

positioning a plurality of wicks in a housing, including a first wick and a second wick;

supplying a first average power level to a first heating element proximate to said first wick when no power is supplied to a second heating element proximate to said second wick; and

supplying a second average power level to said first heating element when power is supplied to said second heating element, said second average power level being lower than said first average power level, said first average power level and said second average power level being determined over at least one second.

9. The method of claim 8 , further comprising the step of supplying said second heating element at approximately said second average power level when said first heating element is powered at said second average power.

10. The method of claim 8 , further comprising the step of selecting to power one of said first heating element, said second heating element, and both said first heating element and said second heating element.

11. The method of claim 10 , wherein if said selecting step is to power said first heating element said first average power level is supplied to said first heating element, if said selecting step is to power said second heating element said first average power level is supplied to said second heating element, if said selecting step is to power both said first heating element and said second heating element said second average power level is supplied to both said first heating element and said second heating element.

12. The method of claim 11 , wherein said second average power level is less that said first average power level.

13. The method of claim 12 , wherein said first wick receives some heat from said second heating element when said second heating element if powered.
