Aspects of the instant disclosure relate to electronic cigarettes; more particularly, to electronic cigarettes including a clearomizer. Various embodiments of the present disclosure are directed to a clearomizer with a refillable electronic cigarette juice tank with a first fill aperture, and a mouthpiece including a second fill aperture. The mouthpiece and the refillable tank rotate relative to one another along a common longitudinal axis to align the fill apertures, and facilitate filling of the refillable tank.

A portable vaporizer system and method are provided. The portable vaporizer system includes a housing having an airflow channel connecting an air inlet to a vapor outlet through a mouthpiece disposed at a first end of the housing. A fluid chamber within the housing can store fluid to be vaporized and is operably connected to an atomizer within the housing, between the air inlet and the vapor outlet. A power control is disposed at a base of the housing and can selectively adjust voltage supplied from a power source to the atomizer for controlling a fluid temperature during the vaporizing process. A sensor is disposed within the housing for detecting fluid levels, power usage, flow rates, and the like. The information detected by the sensor is stored as user data and transmitted to a remote electronic device, wherein a graphical user interface (GUI) displays the user data.

An electrically operated aerosol generation system has a replaceable atomizer. The system includes a housing and an atomizer that can be received within a bore in a grasp ring of the housing. A power supply unit can be connected to the housing. A reservoir contains vaporizable liquid which can be supplied to the atomizer. A mouthpiece assembly is provided and can be actuated relative to the housing in order to separate and eject the atomizer from the housing when the power supply unit is removed.

A vaporizer device includes an inhalation nozzle, a container containing the vaporizable material; and an atomizer arranged for carrying out a single continual atomization process for producing an inhalable vapor. A dosage reminder system for the vaporizer device includes a control module, a reminder determination unit configured for detecting a parameter during the single continual atomization process of the atomizer and a reminder element arranged for providing a reminder effect under control of the control module when the parameter reaches to a predetermined threshold.

A smoking article comprises a tobacco rod and a filter connected to the tobacco rod. The filter comprises a first filter segment and a hollow tube segment downstream of the first filter segment. The hollow tube segment defines a cavity at the mouth end of the filter providing an unrestricted flow channel that extends from the downstream end of the first filter segment to the mouth end of the filter. The length of the hollow tube segment is at least about 25 percent of the overall filter length. Further, the smoking article comprises a ventilation zone comprising at least one circumferential row of perforations provided at a location around the first filter segment.

An atomizing device, an electronic cigarette and a control method for the atomizing device are disclosed. The atomizing device includes a liquid storage assembly configured for storing a tobacco liquid, a liquid guiding assembly connected to the liquid storage assembly and configured for guiding the tobacco liquid, and a heating assembly electrically connected to the battery assembly and configured for atomizing the tobacco liquid; and includes a signal transmitter configured for transmitting a detection signal having a first intensity and a signal receiver configured for receiving a detection signal having a second intensity. The electronic cigarette determines the amount of tobacco liquid on a transmission path of the detection signal according to a difference between the first intensity and the second intensity, and controls on/off of the electrical connection between the heating assembly and the battery assembly according to the determined amount of tobacco liquid.

A cartridge for an e-vaping device includes a housing extending along a longitudinal axis of the cartridge, and an outlet-end insert coupled to the outlet end of the housing. The housing at least partially encloses a pre-vapor formulation reservoir and a vapor generator of the cartridge and further channels light via internal reflection through an interior of the housing. The outlet-end insert includes an outlet in flow communication with the vapor generator, directs the vapor generated by the vapor generator out of the cartridge through the outlet, and further emits the light channeled through the interior of the housing. One or more properties of the light are controllable.

A vaporizer device includes various modular components. The vaporizer device includes a first subassembly. The first subassembly includes a cartridge connector that secures a vaporizer cartridge to the vaporizer device and includes at least two receptacle contacts that electrically communicate with the vaporizer cartridge. The vaporizer device includes a second subassembly. The second subassembly includes a skeleton defining a rigid tray that retains at least a power source. The vaporizer device also includes a third subassembly. The third subassembly includes a plurality of charging contacts that supply power to the power source, and an end cap that encloses an end of the vaporizer device.

The present disclosure provides a driving method, a driving assembly, and an electronic cigarette having the same. The driving method includes: acquiring an output voltage of a power supply of the electronic cigarette; calculating a duty ratio meeting a preset power using the detected output voltage and an effective resistance of a heating assembly; and driving a current circuit of the heating assembly of the electronic cigarette to switch on or switch off according to the duty ratio, so that the heating assembly operates under the preset power. According to the present disclosure, the cost of the electronic cigarette can be lowered, a relatively stable TPM (Total Particulate Matter) value can be output, and the size of the electronic cigarette can be reduced.
