Definitions

  • the present disclosure relates generally to vaporization devices and in particular to vaporizers providing aroma-enhanced user experience profiles.
  • Electronic vaping apparatuses also referred to as vaporization devices or vaporizers, are configured to heat a vaporizable substance to generate an aerosol vapor for inhalation.
  • vaporization substances may include, for example, cannabis products, tobacco products, herbs and/or flavorants.
  • active substances in cannabis extracted to generate concentrates are used as vaporization substances.
  • Cannabis concentrates are typically formed by extracting tetrahydrocannabinol (THC), cannabidiol (CBD) and/or other cannabinoids using a solvent such as, for example, butane, ethanol, carbon dioxide, and/or the like. These types of extraction methods tend to reduce or eliminate terpenes from the final concentrate.
  • terpenes are what give the cannabis its characteristic smell, taste and/or effect (e.g., entourage effect) on the user experience.
  • terpenes there is a desire to add terpenes back into extracted cannabinoid formulations in order to add aroma, flavor and/or effect to the vaporization experience.
  • Previous attempts to address the problem have involved introduction of terpenes into the cannabinoid formulations.
  • the extracted cannabinoids are typically solubilized in a carrier oil.
  • the purpose of the carrier oil is to aid in solubilizing the hydrophobic cannabinoids in the formulation.
  • These cannabinoid formulations may further comprise terpenes.
  • cannabinoid formulations are typically heated to temperatures of between 180-190°C or even higher during vaping.
  • terpenes particularly highly volatile terpenes, will quickly evaporate before they can be inhaled and/or their effects can be experienced by the user.
  • the present disclosure is directed in part to an aroma-enhanced electronic vaporizer that in some embodiments separately stores a vaporization substance and an aroma composition such that they are not mixed prior to vaporization.
  • a potential advantage of this arrangement is that the ingredients that may react with each other and degrade can be kept separate from each other until ready to be used.
  • a vaporizer consistent with the present disclosure may allow for customizable aroma-enhanced user experience, such as providing different combinations of terpenes with cannabinoids to create different effects (e.g., entourage effects).
  • a vaporizer may give users more control over their vaping experience to provide an aroma profile (i.e., aroma character and/or intensity), such as a larger “puff” of the aroma, with the vapor to enable a more complete sensory experience.
  • an aroma profile i.e., aroma character and/or intensity
  • the vaporizer may allow for multi-sensory experiences that may be better, from the perspective of a user, than uni-sensory experiences.
  • an aroma-enhanced electronic vaporizer comprising: a first chamber for storing a vaporization substance; a first channel in fluid communication with the first chamber; a mouthpiece in fluid communication with the first channel and suitable for oral delivery, nasal delivery, or both, of vapor generated from the vaporization substance to a user; and a second chamber for storing an aroma composition, the second chamber comprising at least one outlet suitable for olfactive delivery of aroma from the stored aroma composition to the user.
  • the vaporizer further includes an atomizer in fluid communication with the first chamber to generate the vapor from the vaporization substance.
  • the vaporizer may also or instead include an atomizer in fluid communication with the second chamber to generate the aroma from the aroma composition.
  • the vaporizer may be configured to generate the aroma from the aroma composition via an active mechanism, or configured for aroma generation from the aroma composition via a passive mechanism.
  • the outlet may enable delivery of the aroma via continuous diffusion.
  • the vaporizer further includes a second channel in fluid communication with the outlet to carry the aroma to the outlet.
  • the outlet is provided at a position proximal to the mouthpiece.
  • the outlet is provided at a position distal from the mouthpiece.
  • the outlet is or includes a valve member actuable between a first position and a second position in order to change a size of an opening in the outlet.
  • the outlet is or includes a controllable vent that regulates venting of aroma from the stored aroma composition to outside of the second chamber.
  • the vaporizer is configured for controlled release of the vapor upon actuation of the vaporizer by the user.
  • the controlled release of the vapor is delayed until after release of the aroma through the outlet.
  • the vaporizer further includes a sensor to sense the actuation of the vaporizer by the user and to trigger delayed release of the aroma through the outlet responsive to sensing the actuation.
  • the vaporizer is configured for controlled release of the aroma upon actuation of the vaporizer by the user.
  • the controlled release of the aroma is delayed until after the user has drawn the vapor through the mouthpiece.
  • the vaporizer is configured to trigger generation of the vapor from the vaporization substance responsive to the actuation of the vaporizer.
  • the first chamber is refillable or replaceable.
  • the second chamber may also or instead be refillable or replaceable.
  • the vaporization substance is or includes a liquid, a solid, a gel, a wax, or a liquid concentrate.
  • the vaporizer further includes a second atomizer in fluid communication with the second chamber to generate the aroma from the aroma composition.
  • the outlet enables delivery of the aroma from the aroma composition via continuous diffusion.
  • the vaporization substance is or includes a cannabinoid.
  • the cannabinoid is or includes a cannabidiol (CBD), a tetrahydrocannabinol (THC) or a combination thereof.
  • CBD cannabidiol
