  • Patent number: 12089632
    Abstract: 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: Grant
    Filed: October 9, 2020
    Date of Patent: September 17, 2024

  • Patent number: 12089631
    Abstract: A controller for controlling an atomizing unit, wherein the atomizing unit includes a piezoelectric element substrate including an IDT including a pair of interlocking comb-shaped metallic electrodes, and a liquid supplier configured to supply liquid, which is to be atomized, to the piezoelectric element substrate; wherein the piezoelectric element substrate is configured to atomize the liquid by use of a surface acoustic wave generated by applying a high-frequency voltage to the pair of interlocking comb-shaped metallic electrodes; and the controller is configured to periodically change amplitude and/or a frequency of the high-frequency voltage applied to the pair of interlocking comb-shaped metallic electrodes.

  • Patent number: 12053025
    Abstract: 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.

  • Patent number: 11963550
    Abstract: A inhaler includes a piezoelectric element substrate having an IDT constructed by use of a pair of interlocking comb-shaped metallic electrodes, a liquid supplier for supplying liquid, which is to be atomized, to a front surface of the piezoelectric element substrate on which the pair of interlocking comb-shaped metallic electrodes is positioned, a sensor, which includes at least a pair of detection parts which are opposite to each other, for detecting liquid supplied to the front surface of the piezoelectric element substrate, and a controller for controlling, based on result of detection by the sensor, the liquid supplier in such a manner that the liquid supplier supplies a certain quantity of the liquid to the front surface of the piezoelectric element substrate.
