Atomizer-vaporizer for a personal vaporizing inhaler
View Patent ↗A personal vapor inhaling unit is disclosed. An electronic flameless vapor inhaler unit that may simulate a cigarette has a cavity that receives a cartridge in the distal end of the inhaler unit. The cartridge brings a substance to be vaporized in contact with a wick. When the unit is activated, and the user provides suction, the substance to be vaporized is drawn out of the cartridge, through the wick, and is atomized by the wick into a cavity containing a heating element. The heating element vaporizes the atomized substance. The vapors then continue to be pulled by the user through a mouthpiece and mouthpiece cover where they may be inhaled.
1. A vaporizer, comprising:
a first wick element comprising a porous ceramic, the first wick element adapted to directly contact a liquid held in a reservoir;
a second wick element comprising the porous ceramic;
a heating element disposed through said second wick element;
an air gap defined between at least a first portion of said first wick element and said second wick element, said heating element exposed to said air gap; and,
a housing that defines at least one area on a surface of said first wick element for air to enter at least a second portion of said first wick element;
wherein said housing has a first cylindrical section having a first outer diameter and a first inner diameter, said housing also having a second cylindrical section having a second outer diameter and a second inner diameter, a first chamfer surface transitioning said first outer diameter to said second outer diameter, a second chamfer surface transitioning said first inner diameter to said second inner diameter.
2. The vaporizer of claim 1 , wherein said second outer diameter is configured to form a contact seal with said reservoir that substantially prevents said liquid from flowing out of said reservoir except through said first wick element.
3. The vaporizer of claim 2 , wherein said reservoir comprises:
a housing configured to be inserted in a first end of said vaporizer, said housing configured to hold a fluid to be vaporized in said vaporizer, said housing and an interior surface of said vaporizer forming, when said cartridge is inserted in said vaporizer, at least one space between an exterior surface of said housing and an interior surface of said vaporizer that defines a passage for air to be drawn through said vaporizer from outside said vaporizer.
4. The vaporizer of claim 1 , wherein said at least one area on a surface of said first wick element for air to enter said first wick element is defined by at least one hole through said first and second chamfer surfaces.
5. The vaporizer of claim 4 wherein the longitudinal axis of said at least one hole is substantially perpendicular to the longitudinal axis of said first and second cylindrical sections.
6. The vaporizer of claim 5 , wherein said first wick element is disposed inside, and in contact with, said second inside diameter, and said first wick element is also in contact with said second chamfer surface.
7. The vaporizer of claim 6 , wherein said at least one hole has a hole diameter substantially in the range of 0.02 to 0.0625 inches.
8. The vaporizer of claim 4 , wherein said first wick element has a first wick first outer diameter surface in contact with said second inside diameter of said housing, a first wick second outer diameter surface disposed inside said first inside diameter of said housing, and a first chamfer surface a first wick chamfer surface transitioning said first wick first outer diameter surface to said first wick second outer diameter surface.
9. The vaporizer of claim 8 , wherein substantially all of said first wick second outer diameter surface is in contact with said first inside diameter of said housing.
10. The vaporizer of claim 8 , wherein said first wick second outer diameter surface has a smaller diameter than said first inside diameter of said housing.
11. The vaporizer of claim 1 , wherein said second wick element comprises Magnesia Partial Stabilized Zirconia.
12. The vaporizer of claim 1 , wherein said second wick element comprises Yttria Tetragonal Zirconia Polycrystal.
13. A personal vaporizing unit, comprising:
a chamber configured to receive a cartridge having a first end and a second end and holding a fluid to be vaporized;
a vaporizer configured to remove fluid from said cartridge and having a first wick element comprising a porous ceramic, the first wick adapted to directly contact said fluid to be vaporized, said vaporizer comprising:
a housing that defines at least one area on a first surface of said first wick element to be in contact with said fluid and at least one area on a second surface of said first wick element for air to enter at least a second portion of said first wick element;
a second wick element comprising the porous ceramic;
an air gap defined between at least a first portion of said first wick element and a second portion of said second wick element; and,
a heating element, exposed to said air gap, disposed through said second wick element,
wherein said first wick element has a wick chamfer surface, said wick chamfer surface in contact with a housing chamfer surface of said housing, said housing chamfer surface limiting a first air flow entering said first wick element to at least a portion of said wick chamfer surface.
14. The personal vaporizing unit of claim 13 , wherein said housing is configured to form a seal with said cartridge that substantially prevents said liquid from flowing out of said cartridge except through said first wick element.
15. The personal vaporizing unit of claim 13 , wherein said housing also allows a second air flow to bypass said first wick element.
16. The personal vaporizing unit of claim 13 , wherein said first wick element also contacts said second wick element to allow said fluid to be vaporized to flow from said first wick element to said second wick element.
17. A method of vaporizing a fluid, comprising:
placing said fluid in contact with a first wick element, said first wick element comprised of a porous ceramic;
displacing a set volume of liquid suspended in said first wick element with incoming air, said set volume of liquid exiting said wick into an open cavity as an atomized cloud;
vaporizing at least a portion of said atomized cloud with a heating element;
drawing said fluid into a second wick element; and,
heating said second wick element with said heating element;
wherein said first wick element has a wick chamfer surface, said wick chamfer surface in contact with a housing chamfer surface of a housing, said housing chamfer surface limiting a first air flow entering said first wick element to at least a portion of said wick chamfer surface.
18. The method of claim 17 , further comprising:
providing a negative air pressure to said first wick element.
19. The method of claim 18 , wherein said set volume of liquid is determined by limiting said incoming air drawn through said first wick element by said negative air pressure to a first surface area of said first wick element.
