    摘要： There is disclosed an aerosol delivery device. The aerosol delivery device includes a first aerosol first aerosol sized for pulmonary penetration; and a second aerosol sized to inhibit pulmonary penetration. The second aerosol is transmissible within at least one of: a mammalian oral cavity and a mammalian nasal cavity, and the second aerosol comprising an active component for activating at least one of: one or more taste receptors in said oral cavity and one or more olfactory receptors in said nasal cavity. The second aerosol generator includes a Venturi aperture to generate the second aerosol.
    There is disclosed a consumable for a substitute smoking device and a substitute smoking system. The consumable includes an airflow passage between an upstream inlet of the consumable and a downstream outlet of the consumable. The consumable also includes a porous member for passive aerosol generation. The airflow passage is constricted by the porous member to form a narrowed portion of the airflow passage.
    In another embodiment, the consumable also includes an inner porous member (315) for passive aerosol generation. The airflow passage has an annular portion surrounding at least a portion of the porous member.
    In another embodiment, a portion of the airflow passage is located between a porous surface of the porous member and an opposing airflow passage wall. A minimum distance between the porous surface of the porous member and the opposing airflow passage wall is less than 1000 microns.
    In another embodiment, the consumable also includes a porous member (315) for passive aerosol generation located within the airflow passage. The porous member is tapered along a longitudinal axis of the consumable.
    In another embodiment, the consumable has a longitudinal axis and includes an airflow passage (308) between an upstream inlet of the consumable and a downstream outlet of the consumable. The consumable also includes a porous member (315) for passive aerosol generation. A longitudinal cross section of the airflow passage includes an inclined portion forming a passage angle with the longitudinal axis of the consumable. The passage angle is greater than zero degrees and less than 90 degrees and a wall of the inclined portion is formed from a porous surface (318) of the porous member.
    In another embodiment, the consumable includes an active aerosol generator (304) for generating a first aerosol from a first aerosol precursor (310), and a passive aerosol generator (305) for generating a second aerosol from a second aerosol precursor (316).
    In another embodiment, the consumable also includes an aerosol generator for generating an aerosol. An external portion of the aerosol generator is located at the outlet of the consumable.
    In another embodiment, the consumable also includes an aerosol generator for generating an aerosol at an aerosol generation location. The aerosol generation location is substantially at the outlet located at a mouthpiece of the consumable.
    In another embodiment, the outlet is located at a mouthpiece portion of the consumable; and the mouthpiece portion includes a nozzle for control of an aerosol from the aerosol generator.

    摘要： A humidifier tub includes a first side having an air inlet opening configured to receive the pressurized flow of respiratory gas. A second side opposes the first side. An air outlet opening is configured to discharge the pressurized flow of respiratory gas with added humidity. An inlet passage extends from the air inlet opening toward the second side so that the pressurized flow of respiratory gas travels through the inlet passage in a first direction. A guidance structure is located between the first and second sides and positioned so that a traveling direction of the pressurized flow of respiratory gas changes from the first direction to a second direction upon the pressurized flow of respiratory gas engaging the guidance structure. The guidance structure extends downward from a lid. In addition, the first direction is a lateral direction and the second direction is a downward direction.
