The present invention relates to a low-temperature heat-not-burn electronic cigarette comprised of the first holder including a pipe and to mounting plate with the mounting plate connected to the external wall of the pipe. The mounting plate and the second holder are connected to form an inner cavity with a control plate fixed in the inner cavity and the second holder having a key linked to the buttons on the control plate with the buffer pads. The pipe has a corrugated internal wall and a moveable cigarette cartridge. The pipe is inserted into an outer pipe. The outer pipe has an insulation retaining bracket and a battery in it with the insulation retaining bracket having an installation slot facing the cigarette cartridge and the heating coil on the installation slot.

A fluid permeable heater assembly for aerosol-generating systems includes an electrically conductive flat filament arrangement and a first contact point and a second contact point for electrically contacting the flat filament arrangement. A longitudinal axis is defined between the first contact point and the second contact point. A center resistance Rc is the electrical resistance between two points situated on the longitudinal axis. One of the two points is situated at a distance from the first contact point equal to about 40 percent and the other one of the two points being situated at a distance from the first contact point equal to about 60 percent.

A retractable mouthpiece includes an upper cover of a hollow structure with an receiving cavity, a lower cover that fits with the upper cover, a fastener arranged between the upper cover and the lower cover and housed inside the receiving cavity, a smoking pipe housed inside the receiving cavity, and an elastic component arranged between the smoking pipe and the lower cover. The fastener is sleeved on the smoking pipe, and the smoking pipe is extended out of the upper cover or retracted within the upper cover when the smoking pipe is pressed or rotated. The retractable mouthpiece is both healthy and convenient. An electronic cigarette with the retractable mouthpiece is disclosed.

An electrically operated aerosol-generating system may be configured to detect adverse conditions (e.g., a dry heater). The system may comprise an electric heater comprising at least one heating element for heating an aerosol-forming substrate, a power supply, and electric circuitry connected to the electric heater and to the power supply and comprising a memory. The electric circuitry may be configured to measure an initial electrical resistance (R.sub.1) of the electric heater; measure a subsequent electrical resistance of the electric heater after the measurement of the initial electrical resistance; determine the difference (R) between the initial electrical resistance and the subsequent electrical resistance; determine that an adverse condition is present if the difference is greater than a maximum threshold value (R.sub.max) or less than a minimum threshold value (R.sub.min) stored in the memory; and control a power to the electric heater and/or provide an indication if the adverse condition is present.

A cartridge for an aerosol-generating system includes a storage container containing a supply of an aerosol-forming substrate, a fluid permeable heating element positioned across an opening in the storage container, a protective cover coupled to the storage container and covering the fluid permeable heating element, at least one air inlet, at least one air outlet, and an airflow path from the at least one air inlet to the at least one air outlet. The protective cover is configured such that a portion of the airflow path is between the protective cover and the fluid permeable heating element.

A fluid permeable heater assembly for an aerosol-generating system includes a cap and a substantially flat electrically conductive and fluid permeable heating element. The cap includes a hollow body with a first cap opening and a second cap opening. The first cap opening is opposite to the second cap opening. The heating element is configured to vaporise aerosol-forming substrate. The heating element is mounted on the cap, such that the heating element extends across the first cap opening. A cartridge for an aerosol-generating system includes the heater assembly, a liquid storage portion, a mouth piece, and a retainer.

An electric fireplace (10) includes a fireplace housing (12) and an electrical insert (40). The fireplace housing (12) includes a base panel (30) having a base opening (230A), a back panel (32), and at least one side panel (34). The electrical insert (40) is sized and shaped to fit and be supported and retained within the base opening (230A). Additionally, the electrical insert (40) can include a heater (26), and a controller (28) including a processor that is configured to control operation of the electric fireplace (10). Further, each of the base panel (30), the back panel (32) and the at least one side panel (34) can be manufactured and installed independently of one another. The fireplace housing (12) can further include a front frame (236) that is manufactured and installed independently of each of the base panel (30), the back panel (32) and the at least one side panel (34). Still further, at least one of the back panel (32) and the at least one side panel (34) can be foldable.
