Abstract
An electronic vapor provision system is provided including a pressure drop or air flow sensor for monitoring inhalation by a user through the electronic vapor provision system; and a control unit for detecting the start and end of inhalation based on readings from the sensor. The control unit is configured to monitor the cumulative period of inhalation (Ti) over a predetermined window (Tw); and transfer the electronic vapor provision system to a sleep mode if the cumulative period (Ti) exceeds a predetermined threshold (Th).
Claims12
An electronic vapor provision system including:
- a vaporizer for vaporizing liquid for inhalation by a user of the electronic vapor provision system;
- a power supply comprising a cell or a battery for supplying power to the vaporizer;
- and
- a control unit for controlling the supply of power from the power supply to the vaporizer, the control unit having a sleep mode in which no power is supplied to the vaporizer and a user mode in which power is available for supply to the vaporizer, whereby the control unit reverts from the user mode to the sleep mode in response to one of a plurality of triggers, the plurality of triggers including a trigger representing a predetermined amount of time of inactivity in the user mode and another trigger representing that the vaporizer has been disengaged from the power supply.

- and
- a control unit for controlling the supply of power from the power supply to the vaporizer, the control unit having a sleep mode in which no power is supplied to the vaporizer and a user mode in which power is available for supply to the vaporizer, wherein in the user mode, the control unit is configured to cut power to the vaporizer after a predetermined time from the start of vaporization, whereby the control unit reverts from the user mode to the sleep mode in response to one of a plurality of triggers, the plurality of triggers including a trigger representing a predetermined amount of time of inactivity in the user mode and another trigger representing that the vaporizer has been disengaged from the power supply.
