Aerosol delivery device with aroma diffusion capability
A recently filed patent (Publication Number: US20230309612A1) describes an aerosol delivery device that combines oral and olfactory delivery methods. The device includes a body, an aerosol precursor composition reservoir, an atomizer, at least one aroma diffuser, and at least one aroma reservoir. The atomizer vaporizes the aerosol precursor composition to generate an aerosol for oral delivery, while the aroma diffuser diffuses an aroma composition for olfactory delivery. Importantly, the aroma reservoir is separate from the aerosol precursor composition reservoir.
The patent also describes an aerosol precursor consumable that can be used with the aerosol delivery device. This consumable includes a housing, an aerosol precursor composition reservoir, an atomizer, at least one aroma reservoir, and at least one aroma diffuser. Similar to the device, the atomizer vaporizes the aerosol precursor composition for oral delivery, while the aroma diffuser diffuses the aroma composition for olfactory delivery. The aroma reservoir is separate from the aerosol precursor composition reservoir.
The patent further details various configurations and features of the aerosol delivery device and consumable. For example, the aroma reservoir can be located in the body of the device or consumable, or it can be separable from the body. Additionally, there can be multiple aroma reservoirs and diffusers, with each diffuser in fluid communication with a respective reservoir. The aroma reservoir can also surround at least a portion of the aerosol precursor composition reservoir.
The atomizer in both the device and consumable can be designed with a heater or a vibrating assembly. The consumable includes a mouthpiece portion, and the aroma diffuser is located upstream from the mouthpiece. When a user engages the mouthpiece, the aroma diffuser is positioned near the user's nose.
Overall, this patent introduces an innovative aerosol delivery device and consumable that combine oral and olfactory delivery methods. By separating the aroma reservoir from the aerosol precursor composition reservoir, the device and consumable offer a unique and customizable experience for users. The various configurations and features described in the patent provide flexibility in design and usage.
