Personal vaporizer and aromatherapy diffuser

Abstract

A vaporizer and aromatherapy diffuser includes a base and angled tank floor. A lower end of a coil support tube is configured as a connector to a battery housing and an upper end forms a central air passage. A second air slot communicates with a first air slot in the base. A heating coil within the coil support tube is adjacent at least one opening, and a porous wick surrounds the heating coil. A tank cap forms a sealed fluid tank for holding vaping fluid. When suction is applied, air is drawn upward into the coil support tube through the porous wick and draws botanical extract contained within the sealed fluid tank through the coil support tube into the porous wick for vaporization. The tank cap has a fill hole. A drop tip is secured onto the tank cap and covers the plug to prevent refill.

That which is claimed is: 
     
         1 . A vaporizer and aromatherapy diffuser, comprising:
 a base having an outer surface and upper surface defining an angled tank floor, said base having a central orifice and at least one first air slot extending from the outer surface into the central orifice below the angled tank floor;   a coil support member received within the central orifice of the base and having a lower end extending below the base, and an upper end extending above the base and forming a central air passage, said coil support member having at least one opening formed in the side adjacent the angled tank floor and at least a second air slot below the angled tank floor and communicating with the at least first air slot in said base and configured to receive a heating coil and wick; and   a tank cap received over the base and enclosing the coil support member as a shell forming a fluid tank for holding vaping fluid, said tank cap having at least one third air slot formed below the angled tank floor and communicating with the at least one first and second air slots, and said tank cap having a vapor outlet communicating with the upper end of the coil support member.   
     
     
         2 . The vaporizer and aromatherapy diffuser according to  claim 1 , wherein said vaping fluid comprises a botanical extract. 
     
     
         3 . The vaporizer and aromatherapy diffuser according to  claim 1 , wherein said angled tank floor is configured to assist gravity feeding of said vaping fluid from the fluid tank to a wick and adjacent a heating coil to transfer heat to the vaping fluid. 
     
     
         4 . The vaporizer and aromatherapy diffuser according to  claim 1 , wherein said tank cap includes an upper surface having a fill hole configured to receive vaping fluid to fill the fluid tank and a plug secured into said fill hole. 
     
     
         5 . The vaporizer and aromatherapy diffuser according to  claim 4 , further comprising a drip tip secured onto the tank cap and covering said plug to prevent refill of said sealed fluid tank with a vaping fluid. 
     
     
         6 . The vaporizer and aromatherapy diffuser according to  claim 5 , wherein said drip tip comprises a permanent securement onto the tank cap. 
     
     
         7 . The vaporizer and aromatherapy diffuser according to  claim 1 , wherein said fluid tank has a capacity of 0.3 milliliters to 8.0 milliliters. 
     
     
         8 . The vaporizer and aromatherapy diffuser according to  claim 1 , further comprising an O-ring between said base and tank cap to prevent leakage of vaping fluid therebetween. 
     
     
         9 . The vaporizer and aromatherapy diffuser according to  claim 1 , further comprising an O-ring between said base and coil support member to prevent leakage of vaping fluid therebetween. 
     
     
         10 . The vaporizer and aromatherapy diffuser according to  claim 1 , wherein said fluid tank when filled with a vaping fluid creates a low pressure air pocket that retains the vaping fluid within the fluid tank until a user draws air through the central air passage formed by said upper end of the coil support member and vapor outlet of said tank cap to create a lower air pressure in the central air passage than in the fluid tank and allow vaping fluid to flow into the wick. 
     
     
         11 . The vaporizer and aromatherapy diffuser according to  claim 1 , wherein said tank cap comprises multiple sections, including an upper section and a lower section. 
     
     
         12 . The vaporizer and aromatherapy diffuser according to  claim 1 , wherein the coil support member comprises multiple sections, including upper and lower sections. 
     
     
         13 . A vaporizer and aromatherapy diffuser for botanical extracts, comprising:
 a base having an outer surface and an upper surface defining an angled tank floor, said base having a central orifice and at least one first air slot extending from the outer surface into the central orifice below the angled tank floor;   a coil support member received within the central orifice of the base and having a lower end extending below the base and configured as a connector to connect to a battery housing, and an upper end extending above the base and forming a central air passage, said coil support member having at least one opening formed in the side adjacent the angled tank floor and at least a second air slot below the angled tank floor and communicating with the at least first air slot in said cylindrical base;   a ceramic or mesh heating coil received within the coil support member adjacent the at least one opening, and a wick surrounding the ceramic or mesh heating coil;   a tank cap received over the base and sealed thereto and enclosing the coil support member as a shell forming a sealed fluid tank for holding the botanical extract, said tank cap having at least one third air slot formed below the angled tank floor and communicating with the at least one first and second air slots, said tank cap having a vapor outlet communicating with the upper end of the coil support member;   said tank cap including an upper surface having a fill hole and a plug secured into said fill hole; and   a drip tip secured onto the tank cap and covering the plug secured within the fill hole.   
     
     
         14 . The vaporizer and aromatherapy diffuser according to  claim 13 , wherein said angled tank floor is configured to assist gravity feeding of said botanical extract from the sealed fluid tank to the wick and adjacent the ceramic or mesh heating coil to transfer heat to the botanical extract and thin the botanical extract. 
     
     
         15 . The vaporizer and aromatherapy diffuser according to  claim 13 , further comprising a  510  connector at the lower end of the coil support member and in electrical communication with the ceramic or mesh heating coil.
