Abstract
A mist inhaler device (200) for generating a mist for inhalation by a user. The device includes a mist generator device (201) and a driver device (202). The driver device (202) is configured to drive the mist generator device (201) at an optimum frequency to maximise the efficiency of mist generation by the mist generator device (201).
Claims33
A mist inhaler device for delivering nicotine, the device comprising:
- a liquid to be atomized, the liquid including the nicotine;
- an ultrasonic transducer to atomize the liquid to generate a mist comprising the atomized liquid;
- a housing for housing the ultrasonic transducer the housing comprising an air inlet port and a mist outlet port of a mouthpiece;
- an AC driver for generating an AC drive signal at a frequency to drive the ultrasonic transducer;
- an active power monitor for monitoring the active power used by the ultrasonic transducer when the ultrasonic transducer is driven by the AC drive signal, wherein the active power monitor provides a monitoring signal which is indicative of the active power used by the ultrasonic transducer;
- a processor for controlling the AC driver and for receiving the monitoring signal from the active power monitor;
- and
- a memory storing instructions which, when executed by the processor, cause the processor to:
- A) control the AC driver to output an AC drive signal to the ultrasonic transducer at a predetermined sweep frequency;
- B) calculate the active power being used by the ultrasonic transducer based on the monitoring signal;
- C) control the AC driver to modulate the AC drive signal to maximise the active power being used by the ultrasonic transducer;
- D) store a record in the memory of the maximum active power used by the ultrasonic transducer and the sweep frequency of the AC drive signal;
- E) repeat steps A-D for a predetermined number of iterations with the sweep frequency varying with each iteration such that, after the predetermined number of iterations has occurred, the sweep frequency has been varied between a start sweep frequency to an end sweep frequency;
- F) identify from the records stored in the memory an optimum frequency for the AC drive signal which is the sweep frequency of the AC drive signal at which a maximum active power is used by the ultrasonic transducer;
- and
- G) control the AC driver to output the AC drive signal to the ultrasonic transducer at the optimum frequency to drive the ultrasonic transducer to atomize the liquid.
