Abstract
A flavored vapor generator (100, 200, 300, 400) used for an electronic smoking apparatus (10) comprises a housing; a liquid retention material (155, 255) which is filled, soaked or immersed with a flavored liquid and received inside the housing; an electric heater (150, 350, 450) for heating the liquid retention material (155, 255) to generate flavored vapor; and a sensor (156, 356, 456) for monitoring soaking or wetness conditions of the liquid retention material (155, 255) and providing signals for determining whether the flavored liquid in the liquid retention material (155, 255) is exhausted or almost exhausted.
Claims20
A flavoured vapour generating apparatus comprising a liquid retention device which comprises fibrous liquid retention materials for retaining a flavoured liquid, a liquid reservoir to supply a flavoured liquid to the fibrous liquid retention materials of the liquid retention device, a converter which is operable by electrical power to convert flavoured liquid on the fibrous liquid retention materials into flavoured vapour, and a sensor;
- wherein the sensor is arranged to provide information on the amount or density of flavoured liquid being retained on the fibrous liquid retention materials.
A flavoured vapour generating apparatus comprises a liquid retention device, which is also a liquid reservoir to store a flavoured liquid, a converter which is operable by electrical power to convert stored flavoured liquid into flavoured vapour, and a sensor;
- wherein the sensor and the converter are immersed in a liquid bath of the stored flavoured liquid and the sensor is arranged to provide information on electrical properties due to separation of the converter and the sensor.
An electronic smoking apparatus comprising 65a flavoured vapour generating apparatus and an electronic controller, wherein the flavoured vapour generating apparatus comprises a liquid retention device which comprises fibrous liquid retention materials for retaining a flavoured liquid, a liquid reservoir to supply a flavoured liquid to the fibrous liquid retention materials of the liquid retention device, a converter which is operable by electrical power to convert flavoured liquid on the fibrous liquid retention materials into flavoured vapour, and a sensor;
- or comprises a liquid retention device, which is also a liquid reservoir to store a flavoured liquid, a converter which is operable by electrical power to convert stored flavoured liquid into flavoured vapour, and a sensor;
- wherein the sensor and the converter are immersed in a liquid bath of the stored flavoured liquid and the sensor is arranged to provide information on electrical properties due to separation of the converter and the sensor, wherein the sensor is arranged to provide information on the amount or density of flavoured liquid being retained on the fibrous liquid retention materials;
- and wherein the electronic controller is to control operation of the converter to generate smoke flavoured vapour with reference to output of the sensor.
