The cartridge supporting a plurality of herb bowls each sized to contain a spectrum of a herb compound to allow a user to inhale a vapor of the herb compound. A herb bowl is selected by rotating the cartridge's cylinder plate to a different location in the cartridge each time the user desires to inhale vapor from an unused herb bowl. The cartridge is easily removed from and installed in the carrier. ## Claims ### Claim 1 A multi-portion vaping device comprising: a carrier comprising: a cap assembly comprising: a heater assembly; a cap peg; a spring, wherein the spring biases the cap peg; and a lever assembly including a release button, wherein the cap peg is movable by depressing and releasing the release button; a mouthpiece; and a cartridge removably mounted to the carrier, the cartridge comprising: a cylinder top plate defining an herb aperture; and a cylinder bowl plate that includes a plurality of herb bowls each sized to contain a volume of fresh herb, wherein the mouthpiece, heater assembly, and cap peg define at least a portion of a vapor flow path, further wherein the cylinder bowl plate is rotatable with respect to the vapor flow path such that the plurality of herb bowls can be selectively fluidly coupled with the vapor flow path, and air within the vapor flow path is heated by the heater assembly prior to entering a selected one of the plurality of herb bowls, and the cap peg is configured to selectively contact the cylinder top plate to allow unheated ambient air to flow into the vapor flow path when the cap peg is spaced from the cylinder top plate, and configured to selectively seal the herb aperture to prevent unheated ambient air from flowing into the vapor flow path in the selected one of the plurality of herb bowls. ### Claim 2 (depends on 1) The multi-portion vaping device of claim 1 wherein when a cartridge release mechanism is activated, the cartridge can be pulled away from the carrier for removal from the carrier or pushed into the carrier for installation of the cartridge into the carrier. ### Claim 3 (depends on 1) The multi-portion vaping device of claim 1, wherein the mouthpiece can be inserted into a hole formed in a bottom section of the cartridge so that spent herb compound can be blown out from the herb bowls as necessary. ### Claim 4 (depends on 1) The multi-portion vaping device of claim 1, wherein each of the plurality of herb bowls includes an integrated bed support, which acts as both a screen and a heat sink to filter and cool the vapor. ### Claim 5 (depends on 1) The multi-portion vaping device of claim 1, wherein each cartridge and each of the plurality of herb bowls herb bowl have-include distinct unique, easy to read, identification markings. ### Claim 6 (depends on 1) The multi-portion vaping device of claim 1, wherein one or more magnets hold the cartridge in place in the carrier when a cartridge release mechanism is activated. ### Claim 7 (depends on 1) The multi-portion vaping device of claim 1, wherein depressing and releasing the release button sends thermal pulses through the selected one of the plurality of herb bowls. ### Claim 8 (depends on 1) The multi-portion vaping device of claim 1, further comprising: a male feature disposed on the carrier; and a female feature disposed on a bottom surface of a cylinder plate assembly, wherein the male feature interfaces with the female feature to install the cartridge on the carrier. ### Claim 9 (depends on 1) The multi-portion vaping device of claim 1, wherein heated air in the vapor flow path vaporizes compounds in the volume of fresh herb. ### Claim 10 (depends on 9) The multi-portion vaping device of claim 9, wherein the heater assembly includes an electrically resistive element. ### Claim 11 (depends on 10) The multi-portion vaping device of claim 10, wherein the electrically resistive element is a wire wound heater coil. ### Claim 12 (depends on 11) The multi-portion vaping device of claim 11, wherein the wire wound heater coil is coaxial. ### Claim 13 (depends on 12) The multi-portion vaping device of claim 12, wherein air within the vapor flow path passes through and between the wire wound heater coil and a coil housing results in heat transfer between the wire wound heater coil and the air. ### Claim 14 (depends on 9) The multi-portion vaping device of claim 9, wherein-further comprising: a top distribution screen that distributes heated air flow throughout the volume of fresh herb. ### Claim 15 (depends on 10) The multi-portion vaping device of claim 10, wherein at least one portion of the heater assembly is in contact with a top distribution screen. ### Claim 16 (depends on 14) The multi-portion vaping device of claim 14, wherein the top distribution screen has perforated, radially canted formed slots.
