  • Publication number: 20240188633
    Abstract: A non-combustion-heating-type flavor inhaler, in which a flavor molded body can be fixed in position during use and from which the flavor molded body can be easily removed after use, includes a flavor molded body including a tobacco powder raw material, an aerosol source, and a magnet or a magnet adsorption material that adsorbs the magnet using magnetic force; a flavor molded body accommodation part for accommodating the flavor molded body; a power supply unit provided with a power supply part; a first heating unit for receiving a supply of electric power from the power supply part and generating heat; and a heat-transmitting member provided on the inner wall of the flavor molded body accommodation part. The heat-transmitting member transmits heat from the first heating part to the flavor molded body. The heat-transmitting member includes the magnet adsorption material if the flavor molded body includes the magnet, and includes the magnet if the flavor molded body includes the magnet adsorption material.

  • Publication number: 20240138491
    Abstract: Provided is a technology capable of suppressing the occurrence of scorching in an electrical load of an atomization unit of a suction tool. A method for manufacturing an atomization unit of a suction tool having a liquid storage section and an electrical load comprises: an extraction step (S10) in which a tobacco material subjected to an alkali treatment is heated to extract a flavor component from the tobacco material; a molding step (S20) in which a tobacco residue, which is the tobacco material after being extracted in the extraction step, is cleaned by means of an acidic cleaning liquid having a pH of 7.0 or less to reduce the pH of the tobacco residue to less than 8.0, and the tobacco residue after the cleaning is solidified to mold into a predetermined shape, thereby producing a molded body; and an assembly step (S40) in which an aerosol liquid and the molded body produced in the molding step are stored in the liquid storage section.

  • Publication number: 20240090563
    Abstract: Provided is a flavor molded article that is easy to store and transport, that prevents volatilization of flavor components during storage and transport, and that has a sufficient strength and a good flavor. This production method for a flavor molded article comprises: a step for forming a mixture by mixing a tobacco powder material having an average particle size of at most 100 ?m with an alcohol having 2-7 carbon atoms; a step for compression-molding the mixture; and a step for removing at least a portion of the alcohol from the mixture.

  • Publication number: 20230062322
    Abstract: An electric movable body transmits a signal including identification information identical to identification information retained in a first power storage pack via near-field communication when the first power storage pack is detached from the electric movable body. A charging device wiredly transmits the identification information received from the electric movable body to a second power storage pack. The second power storage pack transmits via near-field communication a signal including the identification information received from the charging device. The electric movable body collates whether or not the identification information included in the received signal matches the identification information retained in the first power storage pack.
