Title
(EN) NON-COMBUSTION TYPE SUCTION DEVICE
(FR) DISPOSITIF D'ASPIRATION DE TYPE SANS COMBUSTION
(JA) 非燃焼式吸引器
Abstract
(EN) Provided is a non-combustion type suction device including a power supply part, a housing part capable of accommodating an aerosol source, a heating part (104) for atomizing the aerosol source, and a suction port part in which a suction port for sucking an aerosol atomized from the aerosol source is provided. The heating part includes a porous ceramic substrate (140), a resistor pattern (142) provided on one face (140b) of the porous ceramic substrate, and a pair of electrode patterns (141) connected to the resistor pattern. The porosity bending coefficient ratio of the porous ceramic substrate is 21 or higher. In the one face of the porous ceramic substrate, a glass layer (143) is provided on a part of the face including at least the resistor pattern, and the resistor pattern is provided on the glass layer.
(FR) L'invention concerne un dispositif d'aspiration de type sans combustion comprenant une partie d'alimentation électrique, une partie boîtier pouvant recevoir une source d'aérosol, une partie chauffante (104) pour atomiser la source d'aérosol, et une partie orifice d'aspiration dans laquelle se trouve un orifice d'aspiration pour aspirer un aérosol atomisé à partir de la source d'aérosol. La partie chauffante comprend un substrat en céramique poreux (140), un motif de résistance (142) disposé sur une face (140b) du substrat en céramique poreux, et une paire de motifs d'électrodes (141) connectée au motif de résistance. Le rapport de coefficient de courbure de porosité du substrat céramique poreux est de 21 ou plus. Sur une face du substrat en céramique poreux, une couche de verre (143) est disposée sur une partie de la face comprenant au moins le motif de résistance, et le motif de résistance est disposé sur la couche de verre.
(JA) 電源部と、エアロゾル源を収容可能な収容部と、エアロゾル源を霧化させる加熱部(104)と、エアロゾル源が霧化したエアロゾルを吸引する吸引口が形成された吸口部と、を備え、加熱部は、多孔質セラミック基板(140)と、多孔質セラミック基板の一方の面(140b)上に設けられた抵抗体パターン(142)と、抵抗体パターンに接続した一対の電極パターン(141)と、を備え、多孔質セラミック基板の気孔率屈曲度係数比は21以上であり、多孔質セラミック基板の一方の面のうち、少なくとも抵抗体パターンを含む一部の面にガラス層(143)が設けられ、抵抗体パターンはガラス層の上に設けられている。
