A smoke generation product and a manufacturing method therefor, which relate to the technical field of tobaccos. The smoke generation product comprises a filter tip base body, a second connecting component, and an aroma generation portion. The filter tip base body comprises a first connecting component, and comprises a cooling portion and a filtering portion that are sequentially disposed in a smoking direction. The filtering portion and the cooling portion are connected by means of the first connecting component. A filtering passage and a cooling passage are in mutual communication. The aroma generation portion is connected to the filter tip base body by means of the second connecting portion, and the aroma generation portion is configured to release smoke by means of heating and make the smoke enter the cooling passage.

An article (1) for use in a non-combustible aerosol provision system is provided. The article comprises a rod comprising a column of aerosol-generating material (3) and a mouthpiece (2) at a first end of the column of aerosol-generating material. The column of aerosol generating material is wrapped in a wrapper (4). A component (5) is located within the wrapper at an opposite end of the column of aerosol-generating material to retain the aerosol generating material within the wrapper. A method for manufacturing an article for use in a non-combustible aerosol provision system is also disclosed.

An aerosol-generating device includes a housing having a first end defining a mouthpiece, a second end, and a cavity defined between the first end and the second end. The device also includes a reservoir within the cavity. The reservoir is configured to store a liquid aerosol-forming substrate. The device also includes an atomizer and a valve within the mouthpiece of the housing. The valve has a first side and an second side. The second side of the valve includes a hydrophilic coating, a hydrophobic coating, or both a hydrophilic coating and a hydrophobic coating.

An aerosol-generating article and a method of manufacturing the same capable of simultaneously improving satisfaction with a tobacco smoke taste and allowing the aerosol-generating article to be manufactured at low cost are provided. The aerosol-generating article according to some embodiments of the present disclosure may include an aerosol-forming substrate portion which includes shredded tobacco leaves and is configured to form an aerosol when electrically heated by an aerosol generation device and a mouthpiece portion which is disposed downstream of the aerosol-forming substrate portion to form a downstream end of the aerosol-generating article. Since the shredded tobacco leaves are cheaper than a reconstituted tobacco sheet, manufacturing costs of the aerosol-generating article may be reduced. Also, unlike the reconstituted tobacco sheet, since the amount of supplementary materials added to the shredded tobacco leaves is small, an off-taste may be reduced, and thus user satisfaction with a tobacco smoke taste may be improved.

A method of constructing a cigar includes the providing of a plurality of frusto-conically shaped tubes, each tube being of a smokable material such as a spirally wrapped layer of tobacco material. The tubes are nested, one tube inside the other tube. The nested tubes are then attached to a mouthpiece having a socket that is internally threaded. The nested tubes and mouthpiece are packaged either filled with tobacco filler material, partially filled, or unfilled in a container.

An aerosol-generating article is provided, including: a rod of aerosol-generating substrate, the aerosol-generating substrate including one or more aerosol formers, a content of aerosol former in the aerosol-generating substrate being between 10 percent and 20 percent by weight on a dry weight basis; a mouthpiece element located downstream of the rod of aerosol-generating substrate, the mouthpiece element including at least one mouthpiece filter segment formed of a fibrous filtration material and a resistance to draw of the mouthpiece filter segment being between 4 mm H.sub.2O and 11 mm H.sub.2O; and a hollow tubular element located between the rod of aerosol-generating substrate and the mouthpiece element, a combined length of the hollow tubular element and the mouthpiece element being between 24 mm and 32 mm. An aerosol-generating system is also provided, including the aerosol-generating article and an aerosol-generating device including a heating chamber to receive the article and a heating element.

This heat-not-burn tobacco product is provided with an electric heating device and a tobacco stick. The tobacco stick is provided with: a tobacco rod part having a tobacco filler containing cut tobacco; a mouthpiece part coaxially connected to the tobacco rod part; and a ventilation hole provided in the mouthpiece part. The electric heating device has a hollow piping heater having a heating chamber formed therein. The hollow piping heater has: a compression tube part that compresses the tobacco rod part from the outer circumferential side when the tobacco stick is inserted; and a heating wall part that is at least partially formed by the compression tube part and heats the tobacco rod part from the outer circumferential side.

A mouthpiece for an article for use in an aerosol provision system and an article for use in an aerosol provision system. A mouthpiece for an article for use in an combustible aerosol provision system includes a body of material at a mouth end of the mouthpiece. The body has a longitudinal axis and a cross sectional area measured perpendicular to the longitudinal axis and comprises fibrous material. The total denier of fibrous material per cross sectional mm.sup.2 of the body is less than about 720 grams/9000 m. The pressure drop across the length of the body is from 1.05 to 1.70 mm water per mm length of the body.

An aerosol-generating device includes a housing having a first end defining a mouthpiece, a second end, and a cavity defined between the first end and the second end. The device also includes a reservoir within the cavity. The reservoir is configured to store a liquid aerosol-forming substrate. The device also includes an atomizer and a valve within the mouthpiece of the housing. The valve has a first side and an second side. The second side of the valve includes a hydrophilic coating, a hydrophobic coating, or both a hydrophilic coating and a hydrophobic coating.
