US 12,369,644 B2 · Vaporizer device with responsive inhalation detection

Abstract

Aspects of the current subject matter are directed to transitioning a vaporizer device between different modes of operation including an active mode, a standby mode, and a deep standby mode. The vaporizer device may include a pressure sensor to measure a first pressure in an air flow path, and an ambient pressure sensor to measure a second pressure corresponding to an atmospheric pressure. The transition between different modes of operation may change the sampling frequency and/or resolution of the pressure sensor and/or the ambient pressure sensor such that sampling occurs at a higher frequency and/or resolution when the vaporizer device is in an active mode. Additionally, a comparison of the pressure in the air flow path with the ambient pressure after a heating element is activated may serve as a verification by the vaporizer device that a user is drawing on the vaporizer device.

Dependent claims

A method, comprising:

measuring, by at least one pressure sensor, a first pressure in an air flow path of a vaporizer device;
measuring, by the at least one pressure sensor, a second pressure corresponding to an atmospheric pressure;
determining, while the vaporizer device is in an active mode, that the first pressure is a first threshold quantity less than the second pressure, wherein the at least one pressure sensor operates at a first sampling frequency in the active mode;
and
in response to determining that the first pressure is the first threshold quantity less than the second pressure, operating the at least one pressure sensor at a second sampling frequency;
wherein the first sampling frequency is less than the second sampling frequency.
