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 having a longitudinal axis, an inlet and an outlet;

a liquid supply in the housing;

an air flow channel in the housing connecting the inlet to the outlet; and

an atomizer assembly in the housing between the inlet and the outlet, including;

a porous body projecting into the liquid supply; and

a heating wire in the atomizer having a central axis oriented substantially perpendicular to the longitudinal axis of the housing.

2. The electronic cigarette of claim 1 further including a battery, a sensor and an electronic circuit board within the housing, with the circuit board electrically connected to the battery, the sensor and the heating wire.

3. The electronic cigarette of claim 1 further including an atomization cavity within the atomizer.

4. The electronic cigarette of claim 1 with the outlet within a mouthpiece that is screwed onto the housing.

5. The electronic cigarette of claim 1 with the liquid supply comprising a fiber material.

6. The electronic cigarette of claim 1 with the porous body of atomizer projecting into the liquid supply comprising a porous bulge section.

7. An electronic cigarette, comprising:

a housing having an inlet and an outlet;

a liquid supply in the housing;

an air flow channel through the housing connecting the inlet to the outlet, with part of the air flow channel extending alongside of the liquid supply; and

an atomizer in the housing between the inlet and the outlet, the atomizer including;

a porous body extending into the liquid supply;

a heating wire in the atomizer having a central axis oriented substantially perpendicular to a longitudinal axis of the housing; and

a battery, a sensor and an electronic circuit board within the housing, with the circuit board electrically connected to the battery, the sensor and the heating wire.

8. An electronic cigarette, comprising:

a housing having an inlet and an outlet ;

a liquid supply, a battery, and an electronic circuit board in the housing;

an air flow channel in the housing between the inlet and the outlet; and

an atomizer in the housing including;

a porous body extending into the liquid supply;

a heating wire having a central axis generally perpendicular to a longitudinal axis of the housing; and

with the circuit board electrically connected to the battery and the heating wire.
