Abstract

The present disclosure relates to aerosol delivery devices. The aerosol delivery devices may include a housing and a cartridge including an atomizer and a reservoir configured to contain an aerosol precursor composition. The cartridge may be configured to move relative to at least a portion of the housing between a retracted configuration and an extended configuration. Related assembly methods are also provided.

Claims

1. An aerosol delivery device, comprising:

a housing;

an actuator moveably engaged with the housing;

a coupler being engaged with the actuator and configured to engage a cartridge comprising an aerosol precursor composition, an atomizer configured to heat the aerosol precursor composition to produce an aerosol, and a mouthpiece configured for passage of the aerosol therethrough;

a track engaged with the housing about a support frame and moveably attached to the actuator such that the coupler is configured to move the cartridge relative to at least a portion of the housing;

a flow sensor disposed on the support frame and configured to measure a change in air pressure resulting from a draw on the mouthpiece of the cartridge; and

a tube positioned in fluid communication between the coupler and the flow sensor, the tube being configured to transmit the change in the air pressure to the flow sensor.

2. The aerosol delivery device of claim 1, further comprising a flow sensor seal engaged with the flow sensor to seal against the flow sensor, such that the tube is positioned in fluid communication with the coupler and the flow sensor seal.

3. The aerosol delivery device of claim 1, wherein the tube is configured to move relative to the movement of the coupler, the actuator being configured to move the cartridge between an extended configuration in which the mouthpiece of the cartridge is exposed relative to the portion of the housing and a retracted configuration in which the mouthpiece of the cartridge is closer to the portion of the housing relative to the extended configuration.

4. The aerosol delivery device of claim 1, wherein the actuator comprises a slider and an external engagement member, the housing defining an opening through which one or both of the slider and the external engagement member extend to allow for coupling therebetween.

5. The aerosol delivery device of claim 4, wherein the tube is directly coupled to the slider, the slider being in fluid communication with the coupler.

6. The aerosol delivery device of claim 4, wherein the track further comprises a longitudinal extension, such that the slider is moveably attached to the longitudinal extension.

7. The aerosol delivery device of claim 6, wherein the longitudinal extension is engaged with the support frame of the track.

8. The aerosol delivery device of claim 1, further comprising a controller engaged with the support frame of the track.

9. The aerosol delivery device of claim 8, further comprising a power source engaged with the controller.

10. The aerosol delivery device of claim 8, further comprising a display engaged with the controller.

11. The aerosol delivery device of claim 10, further comprising a display cover engaged with the display.

12. The aerosol delivery device of claim 11, further comprising an input mechanism engaged with the display cover.

13. The aerosol delivery device of claim 8, wherein the flow sensor is engaged with the controller.

14. The aerosol delivery device of claim 1, wherein the housing comprises a first housing portion and a second housing portion, the track being engagingly received therebetween.

15. The aerosol delivery device of claim 1, wherein the coupler comprises a plurality of electrical terminals engaged with a plurality of electrical wires, the electrical wires being engaged with an electrical connector.

16. The aerosol delivery device of claim 15, wherein the coupler comprises a second plurality of electrical wires engaged with a second electrical connector, the second plurality of electrical wires being engaged with a controller, and the electrical connector being engaged with the second electrical connector.
