Vaporizer for an Electronic Cigarette

Abstract

A vaporizer for an electronic cigarette is fluidically connectable to a liquid store and electrically connectable to a power supply unit in the electronic cigarette. The vaporizer comprises at least one heating element connectable to the power supply unit, an absorbing structure comprising at least one channel configured to receive liquid from the liquid store and conduct the liquid to the at least one heating element, and a pair of electrical contacts. Each electrical contact is arranged about the sides of the at least one channel. The electrical contacts are connectable to an electrical control circuitry when arranged in the electronic cigarette, and the electrical contacts are configured to establish a closed circuit and enable a supply of power to the at least one heating element only when liquid is present in the at least one channel.

Description

FIELD OF THE INVENTION[0001]The present invention relates to an electronic cigarette as well as to a vaporizer for an electronic cigarette.BACKGROUND OF THE INVENTION[0002]The term electronic cigarette, or e-cigarette, is usually applied to a handheld electronic device that simulates the feeling or experience of smoking tobacco in a traditional cigarette. Common e-cigarettes work by heating an aerosol-generating liquid to generate the aerosol that forms a vapor, which is then inhaled by the user.[0003]Accordingly, using e-cigarettes is also sometimes referred to as “vaping”. The aerosol-generating liquid in the electronic cigarette usually comprises nicotine, propylene glycol, glycerin and flavorings. The aerosol-generating liquid is sometimes also designated as “e-liquid” or simply as “liquid”, for short.[0004]Typical e-cigarette vaporizers, i.e. systems or sub-systems for vaporizing the liquid, utilize a cotton wick and coil system to produce vapor from liquid stored in a capsule ...

AI Technical Summary

Benefits of technology

The present invention is a vaporizer for an electronic cigarette that aims to reduce or eliminate the possibility of receiving a dry hit, meaning inhaling heated air with no or insufficient e-liquid vapor present. The invention provides an electronic cigarette that matches this new vaporizer.

Problems solved by technology

If there is a lack of liquid present in the thermal proximity of the heater, the heater temperature tends to increase and there is a risk of overheating the liquid.
