An aerosol generating device includes a first heater for heating a liquid composition accommodated in a liquid storage of a vaporizer, a puff sensor detecting a pressure change within the aerosol generating device, and a controller. The aerosol generating device may determine a puff pattern including a plurality of sections, based on a signal received from the puff sensor. In addition, the aerosol generating device may control an operation of the first heater, based on states of the plurality of sections.

Embodiments of a diffuser device, system, and method for diffusing exhaled vapor that is inhaled from a vaper producing device. In one embodiment, the diffuser device includes a first tubular portion, a second tubular portion, and a removable, disposable filter. The first tubular portion includes a length and a first interior surface that defines a first bore extending through the first tubular portion along the length, the first interior surface defining a first ledge. The second tubular portion includes a second interior surface that defines a second bore. The second tubular portion is removably and rotatably coupled to the first tubular portion such that the second bore is coaxial with the first bore. The removable, disposable filter may include a cylindrical structure sized to be positioned within the first bore between the first ledge and an end of the second tubular portion.

To provide a system for an electronic cigarette such that surrounding people do not notice that the electronic cigarette is being used. A system 1 for an electronic cigarette included an attachment part 5 to be attached to at least a portion of an electronic cigarette 3, and a container 9 in which a main body 7 of the electronic cigarette 3 is placed. The attachment part 5 attaches the main body of the electronic cigarette to the container 9 in such a manner that the main body of the electronic cigarette cannot be seen and the whole or a part of a cartridge attached to the main body of the electronic cigarette protrudes from the container 9.

A smoking pipe has a a combustion bowl, a mouthpiece, and an inhalation conduit. An inhalation check valve is connected to the inhalation conduit and positioned between the bowl and the mouthpiece, oriented to pass smoke of combustion in one direction from the bowl to the mouthpiece. An exhalation check valve is positioned between the mouthpiece and the atmosphere, and is oriented to pass exhalation in one direction from the mouthpiece to the atmosphere. A body is partially fillable to retain water, and the inhalation conduit passes from the bowl into the body and extends to an upper area inside the body, and then turns to extend towards a lower area inside the body, terminating in an open end. The inhalation conduit has a second portion that has an opening in the upper inner area and extends to the inhalation check valve.

An electrically operated aerosol-generating system for receiving an aerosol-forming substrate is provided, including one or more electric aerosol-generating elements; one or more hybrid capacitors configured to supply power to the one or more electric aerosol-generating elements; and a voltage source configured to supply power to the one or more hybrid capacitors to charge the one or more hybrid capacitors.

Vaporizers with protection are disclosed. The vaporizers includes a built-in child protective mechanism adapted to connect and disconnect the power source from the heating element of the vaporizer thereby mitigating the ability of a child to activate the vaporizer.

A vaporization device comprises one or more batteries disposed in a body portion having a first longitudinal center plane and two or more identical substance cartridges each adapted to detachably attach to the body portion in first and second orientations relative to the first longitudinal center plane.

The present invention provides an electronic cigarette and a soft power source stem thereof. The power source stem includes a power source stem sleeve with a built-in battery. One end of the power source stem sleeve is closed, while the other end thereof is provided with an absorption stem connector for connecting with an absorption stem of the electronic cigarette. Herein, the power source stem sleeve is made of soft material; and an outer wall of the power source stem sleeve is sleeved with a holding member for clamping the absorption stem connector and power source stem sleeve. The electronic cigarette and a soft power source stem have good experience when held in hand, are able to reduce production cost, have stable construction and are convenient to attach a paper layer thereon.
