Abstract

The present invention relates generally to electronic smoking devices and in particular electronic cigarettes. A mouthpiece for an electronic smoking device has an elongated housing having ports at opposite ends; a central passage formed as a hollow channel through the housing in communication with the ports, contact terminals for connecting to a battery of the electronic smoking device and conductive elements connected to the contact terminals, the conductive elements being configured for connecting, to the battery, an tempering element for tempering an aerosol produced by the electronic smoking device. Using the tempering element, aerosol passing through the central passage can be tempered and loss of aerosol due to condensation is reduced.

Claims

1. A mouthpiece for an electronic smoking device, the mouthpiece comprising:

an elongated housing having an attachment port at a first end and an inhalation port at an opposing second end;

a central passage formed as a hollow channel through the housing, the central passage in communication with the attachment port and the inhalation port;

contact terminals for connecting to a battery of the electronic smoking device;

conductive elements connected to the contact terminals, the conductive elements being configured for connecting, to the battery; and

a tempering element electrically connected to the conductive element and located along the central passage, the tempering element for heating the air in the central passage, and wherein tempering element is configured to operate below a temperature at which the aerosol evaporates.

2. The mouthpiece of claim 1 wherein the mouthpiece is an atomizer/liquid reservoir portion of the electronic smoking device and the contact terminals are arranged at the attachment port, the atomizer/liquid reservoir portion further comprising:

a liquid reservoir located within the elongated housing and communicatively coupled with the central passage; and

an atomizer arranged in the central passage operable when connected to the battery for the electronic smoking device to atomize liquid stored in a liquid reservoir such that the aerosol is provided in the central passage.

3. The mouthpiece of claim 2 further comprising the liquid reservoir.

4. The mouthpiece of claim 2 further comprising:

a second mouthpiece configured for attachment to the mouthpiece, the second mouthpiece including;

a second housing including a second attachment port at a first end and a second inhalation port at a second end;

a second central passage formed as a hollow channel through the second housing, the second central passage in communication with the second attachment port and the second inhalation port, the second central passage is adapted to receive the aerosol from the central passage through the second attachment port;

a coupling element configured for releasably attaching the inhalation port to the second attachment port of the second mouthpiece; and

a second battery within the second housing, the second battery electrically coupled to a second tempering element using a plurality of coupling elements, the second tempering element adapted to heat air in the second central passage to reduce condensation of the aerosol.

5. The mouthpiece of claim 1 wherein the tempering element is arranged in the central passage and connected to the conductive elements.

6. The mouthpiece of claim 5 wherein the tempering element extends from the inhalation port at least along a section of the central passage.

7. The mouthpiece of claim 6 wherein the tempering element is arranged around the hollow channel of the section of the central passage.

8. The mouthpiece of claim 6 wherein the tempering element surrounds a further element surrounding the section of the central passage.

9. The mouthpiece of claim 1 wherein the mouthpiece further comprises further contact terminals arranged at the inhalation port, the further contact terminals adapted for connecting the battery to the tempering element.

10. The mouthpiece of claim 9 wherein a further attachment port of a further mouthpiece is configured for attachment to the inhalation port of the mouthpiece, and wherein the further contact terminals are adapted to contact with the contact terminals.

11. The mouthpiece of claim 10 wherein the further mouthpiece includes a further central passage, and the tempering element is arranged in the further central passage and connected to the conductive elements.

12. The mouthpiece of claim 10, further comprising at least one coupling element configured for releasably attaching the inhalation port to the further attachment port of the further mouthpiece.

13. The mouthpiece of claim 1 wherein the mouthpiece further comprises a filter arranged in the central passage.

14. The mouthpiece of claim 1 wherein the mouthpiece further comprises a catalytic converter arranged in the central passage.

15. The mouthpiece of claim 1 wherein the tempering element is operable when connected to the battery to temper the aerosol such condensation of the aerosol is reduced.

16. An electronic smoking device comprising:

a battery portion including a battery and first contact terminals electrically coupled to the battery;

a mouthpiece adapted to attach to the battery portion, the mouthpiece including;

an elongated housing having an attachment port at a first end and an inhalation port at an opposing second end;

a central passage formed as a hollow channel through the housing in communication with the attachment port and the inhalation port;

a tempering element located in the central passage and adapted to heat air in the central passage to reduce condensation of an aerosol, wherein tempering element is configured to operate below a temperature at which the aerosol evaporates;

second contact terminals coupled to the elongated housing and configured to connect to the first contact terminals; and

conductive elements connected to the second contact terminals and the tempering element, the conductive elements configured for connecting the battery to the tempering element for heating the air in the central passage.

17. The electronic smoking device of claim 16 wherein the mouthpiece is an atomizer/liquid reservoir portion of the electronic smoking device and the second contact terminals are arranged at the attachment port, the atomizer/liquid reservoir portion further comprising:

an atomizer arranged in the central passage operable when connected to the battery for the electronic smoking device to atomize liquid stored in a liquid reservoir such that the aerosol is provided in the central passage.

18. The electronic smoking device of claim 16 wherein the tempering element extends from the inhalation port at least along a section of the central passage.

19. The electronic smoking device of claim 16 wherein in the tempering element surrounds the section of the central passage.
