A tobacco baking device, comprising a mouthpiece component, a baking component, and a filter component, where the filter component is located below a baking component; the mouthpiece component is located above the baking component; the baking component is detachably connected to the filter component; where there is sealed connection on the butted terminal portions of the mouthpiece component, the filtration component and the baking component; an air flow channel is provided between the mouthpiece component, the filter component, and the baking component. Vapor goes down along the air flow channel to the filtration component, and goes up after being filtered by the filter component and is released via the mouthpiece component. As the vapor is filtered by the filter component, harmful substances in the vapor are greatly reduced, and also cool the vapor and the whole device, so as to enable the device to be more suitable for using.

A fluid pipe device is provided, which includes a pipe member forming a flow channel for flowing a fluid; a heating member for generating heat to heat the pipe member; a metal heat transfer member abutting against the heating member and conducting the heat to the pipe member; and a terminal member electrically connecting the heating member and the heat transfer member. The heat transfer member includes a first heat transfer member and a second heat transfer member, and at least one of the first heat transfer member and the second heat transfer member forms the terminal member at one portion, and the first heat transfer member is provided in the pipe member in such a way as not to be exposed inside the flow channel of the pipe member.

A heater is provided that includes at least one resistive heating element having a material with a non-monotonic resistivity vs. temperature profile and exhibiting a negative dR/dT characteristic over a predetermined operating temperature range along the profile. The heater can include a plurality of circuits disposed in a fluid path to heat fluid flow.

A heater assembly for a vaporizer including a heat exchanger with an interior surface having at least one ridge and groove, and a heater positioned in the bore. An air management system for a vaporizer including a valve that allows air to be drawn through a valve inlet and pumped through a valve outlet with a pump or drawn through the valve outlet and inlet with external suction. A system and method for generating a workflow sequence for a vaporizer. The system and method including receiving task selections arranged in a task order, and generating a workflow sequence that is configured to instruct the vaporizer to sequentially perform the tasks associated with the task selections in the task order. A vaporizer that is configured to receive task selections arranged in a task order and sequentially perform the tasks associated with the task selections in the task order.

A vaporization core, a method of manufacturing the same, and an electronic vaporization device comprising the same are disclosed. The vaporization core includes a tubular porous substrate for forming a vaporization cavity and configured to guide liquid outside the tubular porous substrate into the vaporization cavity and a heating element disposed on an inner wall of the tubular porous substrate and configured to heat and vaporize the liquid guided into the vaporization cavity.

A ceramic body being configured of mainly BaTiO.sub.3-based crystalline particles in which a part of Ba is substituted with at least one rare earth element, wherein the ceramic body contains Ba.sub.6Ti.sub.17O.sub.40 crystalline particles of from 1.0 to 10.0% by mass.

A heater includes a ceramic core and a heating wire. The ceramic core includes a concave bottom end.

A heater includes a ceramic core and a metal wire secured to the ceramic core. The ceramic core includes three through holes.

A wax warmer includes a reservoir for receiving a wax melt, a housing defining an interior volume and configured to receive the reservoir, and a hermetically sealed heater engine positioned within the interior volume and in thermal contact with the reservoir.

An aerosol-generating device may include a housing having flexible portion along its length. The flexible portion is configured to transition between a relaxed or unloaded configuration and a flexed or deflected configuration. A flexible heating element and mouthpiece may also be disposed in the housing. When the housing is in a relaxed or unloaded configuration, the flexible heating element and the mouthpiece are at least partially longitudinally aligned with the flexible portion of the housing.
