The present disclosure relates to a replaceable vaporizer assembly and an electronic cigarette having the replaceable vaporizer assembly. In certain embodiments, the electronic cigarette may include an electronic cigarette body, and a replaceable vaporizer assembly. The electronic cigarette body may include a mouthpiece installed in a mouthpiece base, a connector base, a mounting base, an E-liquid storage tank, and a connector. The mounting base and the connector base are threadedly connected through a first internal thread of the mounting base and an external thread of the connector base to form an air chamber inside of the mounting base and the connector base. When in operation, outside air enters the air chamber through the multiple air intake openings and is vaporized by the replaceable vaporizer assembly, goes up through multiple air gaps between the mounting base and the connector base, and exits the electronic cigarette body through the mouthpiece.

Present disclosure relates to a heating tube, a replaceable vaporizer assembly and an electronic cigarette having the replaceable vaporizer assembly. In certain embodiments, the electronic cigarette may include an electronic cigarette body, and a replaceable vaporizer assembly. The electronic cigarette body may include a mouthpiece installed in a mouthpiece base, a connector base, a mounting base defining multiple air intake openings, an E-liquid storage tank, and a connector. The mounting base and the connector base are threadedly connected through an internal thread of mounting base and an external thread of connector base to form an air chamber inside the mounting base and connector base. When in operation, outside air enters the air chamber through the multiple air intake openings and is vaporized by the replaceable vaporizer assembly, goes up through multiple air gaps between the mounting base and the connector base, and exits the electronic cigarette body through the mouthpiece.

A control unit for an electronic vapor provision system includes a battery for providing electrical power to a heater which is used to produce vapor. The battery is a lithium iron phosphate battery. The battery provides an output voltage which remains at an approximately constant voltage level as the battery is discharged.

The present disclosure provides an aerosol precursor consumable, and an aerosol delivery device that comprises a control unit that defines a receiving chamber, and a removable and replaceable aerosol precursor consumable, at least a portion of the consumable configured to be received into the receiving chamber. The aerosol precursor consumable comprises a housing defining an outer wall, an aerosol precursor composition reservoir located in the housing and configured to contain an aerosol precursor composition, an atomizer located in the housing, and at least one aroma diffuser. The atomizer is configured to vaporize the aerosol precursor composition to generate an aerosol for oral delivery to a user, and the at least one aroma diffuser is configured to diffuse an aroma composition for olfactory delivery to the user.

An electronic inhalation device comprising a mouthpiece and a control unit, the control unit comprising a power cell and a computer, where the computer comprises a computer processor, a memory and an input-output means; wherein the device further comprises a transmitter connected to the computer and the computer is configured in use to collect and store use data relating to a user's use of the device in the computer memory and transmit the use data.

An electronic smoking device (10) is provided including a power supply portion (12) comprising a power supply (18), an atomizer/liquid reservoir portion (14) comprising a liquid reservoir (34) storing a liquid, and an atomizer (26) adapted to atomize the liquid stored in the liquid reservoir (34) when operated by the power supply (18). The atomizer (26) extends away from the liquid reservoir (34) in a first direction (L). The atomizer (26) comprises first atomizer sections (28a, 28b, 28c, 28d), wherein each of the first atomizer sections defines an opening (50a, 50b, 50c, 50d) that is at least partly encircled by the first atomizer section. The sizes of the openings defined by the first atomizer sections decrease with increasing distance of the first atomizer sections from the liquid reservoir in the first direction.

An aerosol-generating system may include a liquid storage portion configured to hold aerosol-forming substrate, a vaporizer, and a pump. The liquid storage portion includes a movable wall and an outlet. The vaporizer includes a heating element having a structure that at least partially defines an internal passage. The pump may deliver liquid aerosol-forming substrate from the outlet of the liquid storage portion to the internal passage of the heating element. The pump may include a micro stepper motor with a drive shaft that is configured to rotate a particular amount based on performing an individual step, a piston connected to the movable wall, and a lead screw connecting the drive shaft to the piston and configured to translate rotation of the drive shaft into axial movement of the piston and the movable wall. The vaporizer may at least partially vaporize the delivered liquid aerosol-forming substrate.

A cartridge for an e-vaping device includes a reservoir configured to hold a pre-vapor formulation and a channel structure that includes a channel surface with one or more open-microchannels. An open-microchannel in the channel structure may be in fluid communication with the reservoir and may transport pre-vapor formulation from the reservoir to a heating element based on capillary action of the pre-vapor formulation through the open-microchannels. The heating element may vaporize the pre-vapor formulation drawn through one or more open-microchannels. The cartridge may be independent of fibrous dispensing interfaces, including one or more wicks. Fabrication of such a cartridge may be simplified, faster, cheaper, some combination thereof, or the like relative to fabrication of a cartridge that includes a fibrous or soft dispensing interface to draw pre-vapor formulation from a reservoir to a heating element.

A personal vapor inhaling unit is disclosed. An electronic flameless vapor inhaler unit that may simulate a cigarette has a cavity that receives a cartridge in the distal end of the inhaler unit. The cartridge brings a substance to be vaporized in contact with a wick. When the unit is activated, and the user provides suction, the substance to be vaporized is drawn out of the cartridge, through the wick, and is atomized by the wick into a cavity containing a heating element. The heating element vaporizes the atomized substance. The vapors then continue to be pulled by the user through a mouthpiece and mouthpiece cover where they may be inhaled.

Cartridges for vaporizer devices are provided. In one exemplary embodiment, the cartridge can include first and second storage chambers each configured to hold a respective fraction of a vaporizable material, a vaporization chamber that includes an elongate member that is in fluid communication with the first and second storage chambers and configured to receive the vaporizable material, a magnetic element disposed within a channel of the elongate member, and a conductive element that is configured to generate a first motive force to drive the magnetic element between first and second positions and further configured to substantially vaporize the vaporizable material within the elongate member. Vaporizer devices are also provided.
