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.

Electronic cigarettes may include an electronic cigarette, and a replaceable vaporizer assembly. Electronic cigarette may include an electronic cigarette body, and a replaceable vaporizer assembly. In certain embodiments, the electronic cigarette body may include a mouthpiece, an E-liquid storage tank, an E-liquid refill cap, a mounting ring, a connector, and a vaporizer mounting base having an internal thread. The replaceable vaporizer assembly may include an external thread of a vaporizer assembly base. The replaceable vaporizer assembly may be replaced by removing the mouthpiece, unscrewing the replaceable vaporizer assembly to detach the external thread of the vaporizer assembly base from the internal thread of the vaporizer mounting base, pulling up the replaceable vaporizer assembly, replacing a new replaceable vaporizer assembly, and reinstalling the mouthpiece back in place. The electronic cigarette includes a top adjustable air intake. The mouthpiece may be used to adjust the air intake by rotating the mouthpiece.

A control body is coupled or coupleable with a cartridge that is equipped with a heating element and contains an aerosol precursor composition, the control body and cartridge forming an aerosol delivery device. The control body includes a control component to control the heating element to activate and vaporize components of the aerosol precursor composition. The control body also includes a gas sensor configured to detect a presence of gas in an environment of the control body, and the gas sensor or control component are further configured to control operation of at least one functional element of the aerosol delivery device in response to the presence of gas so detected.

In general, embodiments of the present invention are related to an apparatus and method of use of such apparatus for the personal filtration of air. Particularly, embodiments of this invention relate to the filtration of air for a singular individual to inhale.

The invention relates to a slide-on attachment (500) for use with an electronic smoking device (10), the slide-on attachment (500) comprising a body (100) and a plurality of end-caps (300) fitted on the body (100), the body (100) comprising a plurality of cavities, the plurality of cavities (106, 108) comprising a central cavity (106) capable of facilitating fitting the slide-on attachment (500) on the electronic smoking device (10), and at least one lateral cavity (108) comprising a material imbibed with flavored fluid.

A heating assembly, an atomizer and an electronic atomizing device are disclosed. The heating assembly includes a chassis and a heating component. The chassis may include a first wall having a top surface and a bottom surface opposite to the top surface, the first wall defining an air vent extending through the bottom surface, an air entering plate being connected with the first wall and covering the air vent, the air entering plate defining at least one air entering hole communicating with the installation space and the air vent, wherein the first wall and the second wall define the installation space. A heating component may be disposed in the installation space, a length of the at least one air vent is greater than that of the air entering hole in a direction from the bottom surface to the top surface.

Systems and methods of an electronic drug delivery system for use in a treatment program (e.g., a smoking cessation program). The delivery system can include a mobile platform and a hand-held inhalation delivery device having a controller circuit coupled to a power source, sensors, aerosolizer drivers, and a rescue button, and a pod removably coupled to the delivery device. The delivery system generates an aerosol mixture from substances in the pod in accordance with the treatment program, and delivers the aerosol mixture for inhalation by a user. The controller circuit individually and dynamically controls the aerosolizer drivers to generate signals that drive a plurality of thermal, or non-thermal, aerosolizers of the pod to generate individually tailored aerosol mixtures from multiple substances in the aerosolizer pod. The generated aerosol mixtures can have various percentages of the substances, and have different aerosol droplet sizes during different portions of the treatment program.

A flavor aspirator includes: a weight-concentrated part that is provided at a position off the mouthpiece end and closer to the mouthpiece end side than to a midpoint position between the mouthpiece end and the distal end, and that accounts for at least approximately half of a total weight of the flavor aspirator. A value of (a length from the mouthpiece end to the center of gravity)/(a total length defined by a length from the mouthpiece end to the distal end) is in a range of 0.20 to 0.45.
