Abstract

An electronic cigarette includes a shell and a mouthpiece. The external wall of the shell has an air inlet. An atomizer and a liquid-supply are in contact with each other. The air inlet, atomizer, an aerosol passage, and a mouthpiece are sequentially interconnected.

Claims

1. An electronic cigarette comprising;

a housing;

a mouth piece on the housing;

an LED at a first end of the housing;

an air inlet leading into the housing;

a battery within the housing;

an electronic circuit board within the housing;

a sensor within the housing;

an atomizer within the housing;

a stream passage within the housing leading from the inlet to the atomizer;

a cavity arranged in the atomizer;

a liquid-supply within the housing; and

an aerosol passage leading from the atomizer to the mouthpiece; and

with the liquid-supply in physical contact with the atomizer; and

a heating element within the cavity.

2. An electronic cigarette, comprising:

a housing;

a mouthpiece on the housing;

an LED at a first end of the housing;

an air inlet for providing air into the housing;

a battery and a sensor electrically connected to an electronic circuit board within the housing, with the sensor in a stream passage in the housing;

an atomizer within the housing, with the atomizer having a heating element within a cavity, and with the atomizer making contact with a liquid-supply, to provide for movement of liquid to the atomizer via capillary action; and

an aerosol passage extending from the atomizer to the mouthpiece.

3. The electronic cigarette of claim 2 with the heating element comprising platinum wire, nickel chromium alloy or iron chromium aluminum wire with a rare earth element.

4. The electronic cigarette of claim 2 wherein the heating element comprises a wire coil.

5. The electronic cigarette of claim 2 with the liquid-supply comprising a porous body.
