Patent number: 12089632Abstract: An inhaler includes an atomizing unit including a piezoelectric element substrate having a first IDT including a pair of interlocking comb-shaped electrodes. The atomizing unit is configured to atomize liquid by a surface acoustic wave generated by applying a high-frequency voltage to the pair of interlocking comb-shaped electrodes, and a controller is configured to monitor a resonant frequency of the pair of interlocking comb-shaped electrodes and apply a voltage to the pair of interlocking comb-shaped electrodes at a frequency determined based on the monitored resonant frequency.Type: GrantFiled: October 9, 2020Date of Patent: September 17, 2024Assignee: JAPAN TOBACCO INC.Inventors: Yuki Minami, Takahisa Kudo, Michihiro Inagaki, Jumpei Inoue, Yuki Abe, Adam Geernaert, Franck Rubiconi, Simon Cox, Rishi Jobanputra

Patent number: 12053025Abstract: A non-combustion heating-type smoking article comprises: a mouthpiece having a suction port hole; a flavor source accommodation section that accommodates a flavor source, and that has a vapor discharge port that discharges a vapor component generated by evaporation of the flavor source; a heater for heating and evaporating the flavor source; a chamber section for establishing communication between the vapor discharge port and the suction port hole, and temporarily storing the vapor component generated by evaporation of the flavor source; and an air intake hole that establishes communication between the inside and the outside of the chamber section. The vapor discharge port is opened to only the chamber section, and during each suction, the vapor component that has accumulated in the chamber section is mixed with intake air that has flowed into the chamber section from the air intake hole and is then transported to the suction port hole.Type: GrantFiled: August 13, 2020Date of Patent: August 6, 2024Assignee: JAPAN TOBACCO INC.Inventors: Takahisa Kudo, Nobuyuki Ishikawa
