The present disclosure provides a power supply for an aerosol generator and an aerosol generator having the same. The power supply may include a power supplying main body including a mounting chamber, a pneumatic switch, a seal seat, and an adjusting element. The seal seat may be in socket joint with the pneumatic switch and may be accommodated in the mounting chamber, and a peripheral part of the seal seat may be elastically abutted against the wall of the mounting chamber. One end of the mounting chamber may include an inlet hole which communicates the air supplying end of the pneumatic switch with ambient air, and the other end is provided with the vent hole which may communicate the sensing end of the pneumatic switch with ambient air. The adjusting element may be rotatably connected to the power supplying main body.

An electronic cigarette (“e-Cig”) may include functionality for targeted marketing. The marketing may be through communications with a computing device, such as a smartphone. For example, a smartphone application may be used for monitoring e-Cig usage and collecting data regarding the user and the usage. That data may result in targeted marketing. In another example, location information may also be used for targeted advertisements from a retailer.

Methods and vaporizer apparatuses that estimate, measure and/or predict the amount of vapor and/or material (including active ingredients) released by the vaporizer apparatus. In particular, described herein are electronic vaporizers and methods of using them that determine a dose/amount of vapor and/or a material in the vapor based primarily or exclusively on the electrical and thermal properties, e.g., power or energy applied to the vaporizing element (e.g., heating coil) and the temperature of the material immediately before and as it is vaporized. Dose information may be used to control operation of the device and/or reported to the user.

A measurement circuit and a measurement method for measuring and updating a voltage resolution of an electronic atomizer circuit are provided. In the measurement circuit, a comparison unit is configured to compare a first preset value and a second preset value to obtain a voltage difference, an accumulation and subtraction unit is configured to perform counting according to a comparison result, and a control unit is configured to adjust the voltage difference between two compared voltage input terminals, thereby calculating a voltage resolution of the control unit, avoiding the impact of the actual error of the first constant current source and the unit resistor on the actual voltage resolution, and ensuring the measurement accuracy. In addition, an accurate to-be-measured voltage is calculated, and a measurement value of the to-be-measured voltage is corrected, to ensure the high measurement accuracy of the to-be-measured voltage and the output power.

A aerosol-generating system includes a liquid storage portion, a liquid pressure sensor within the liquid storage portion, and a control unit that is in communication with the pressure sensor. The aerosol-generating system further includes an atmospheric pressure sensor in communication with the control unit. The atmospheric pressure sensor is configured to sense the atmospheric pressure of the environment. The control unit is configured to receive the pressure signals from the liquid pressure sensor and the atmospheric pressure sensor. The control unit is further configured to determine the fill level of the liquid aerosol-forming substrate based on a comparison of the pressure signals from the liquid pressure sensor and the atmospheric pressure sensor.
