Abstract: The present invention provides a nicotine inhaler including: a body including a housing and a venturi tube disposed in the housing; a liquid nicotine storage; and a liquid supplying tube that supplies the liquid nicotine into the venturi tube, wherein the venturi tube includes an inlet pipe section communicating with an air intake port at one end of the housing, a central pipe section having a liquid injection hole on a wall thereof, and an outlet pipe section communicating with an inhalation port at the other end of the housing, and the liquid supplying tube is disposed to communicate with the liquid nicotine storage and the liquid injection hole of the central pipe section.

Abstract: There is provided a smoking material wrapper having micropores, wherein when the smoking material wrapper is divided into three regions at equal intervals from an upstream distal end based on the case where the smoking material wrapper is applied to a smoking article, an average porosity is greater as a region becomes closer to a downstream. According to an embodiment of the present disclosure, the micropores have a pore size of 10 ?m to 50 ?m, and are formed by a perforation method using plasma. The wrapper may maintain functionality as a wrapping material due to low visibility or the like, and may minimize a dilution ratio decreased due to burning of a smoking material unit while maintaining a basic dilution ratio when the smoking material wrapper is applied to a smoking article.

Abstract: Provided herein are an aerosol-generating article having a flavor optimization function and an aerosol generation system including the same. The aerosol-generating article according to some embodiments of the present disclosure includes a filter portion, a medium portion which includes an aerosol-generating substrate and has a downstream end portion connected to an upstream end portion of the filter portion, and a wrapping structure which wraps around at least a portion of the filter portion or the medium portion. Here, the wrapping structure may include a heat conduction member or a heat conduction limiting member to appropriately control thermal energy delivered to the aerosol-generating substrate. Accordingly, the flavor and taste of tobacco smoke of the aerosol-generating article may be improved.

Abstract: A sidestream smoke removing device includes a housing having a smoking space defined therein, an article inserting part positioned on one end of the housing and having an open area through which a smoking article is inserted into the smoking space, and a sidestream smoke processing part positioned at a distance from an upstream end of the smoking article inserted into the smoking space and configured to process sidestream smoke produced from the smoking article. The sidestream smoke processing part includes a filter including a filter included of pressed activated carbon having a plurality of holes allowing the sidestream smoke to pass therethrough and a ventilation fan configured to allow the sidestream smoke to be discharged through the filter. The sidestream smoke removing device obtains superior functionality in terms of a sidestream smoke removal rate and deodorizing performance while maintaining a suitable flow rate therein.

The sidestream smoke processing part includes a filter including a pleated HEPA filter capable of filtering the sidestream smoke and a ventilation fan configured to allow the sidestream smoke to be discharged through the filter. The sidestream smoke removing device using a pleated HEPA filter obtains superior functionality in terms of the removal rate of sidestream smoke and durability while obtaining a suitable flow rate for smoking in the sidestream smoke removing device.

Abstract: The present invention relates to a nicotine inhaler including: a body including a tube-shaped housing; a first liquid storage part including liquid nicotine; a second liquid storage part including a smoke generating liquid; a heating element generating smoke by heating the smoke generating liquid; and a switch disposed on the outer surface of the body.

Abstract: An aerosol inhaler including a nicotine transition unit, wherein the nicotine transition unit includes: a first container filled with a nicotine-containing solution and a propellant; and a second container connected to the first container to be filled with the liquid in the first container, and the propellant exists in a liquid state and a gas state in the first container. The nicotine transition unit enables prediction and control the amount of nicotine transition so that the actual amount of nicotine transition does not deviate significantly from the predicted value.

Abstract: A sidestream smoke removing device includes a housing having a smoking space defined therein, an article inserting part positioned on one end of the housing and having an open area through which a smoking article is inserted into the smoking space, and a sidestream smoke processing part positioned at a distance from an upstream end of the smoking article inserted into the smoking space and configured to process sidestream smoke produced from the smoking article. The sidestream smoke processing part includes a plasma ion filter configured to generate plasma ions using a high voltage electrode and a ventilation fan configured to allow the sidestream smoke to be discharged through the plasma ion filter. The sidestream smoke removing device obtains superior effects in terms of a sidestream smoke removal rate and deodorizing performance without significantly reducing the flow rate after the application of the filter.
