Abstract

A cartomizer assembly of an electronic cigarette which is formed from automated assembly compatible parts comprises a container assembly including a container and a heater coil surrounding a wick in an airflow space of the container. The entire coil of the heater coil is inside the container and the heater coil is configured to heat liquid on the wick to generate an aerosol mist during a vaporization process. A liquid storage space is in liquid communication with the wick and is operable to supply liquid to the wick. The heater, the wick, and the container are shaped such that the heater and wick can be dropped into the container during automated assembly thereof and be directed to and located at a desired location in the container.

Claims

1. A cartridge assembly of an electronic vaping device configured to connect with a battery portion of the electronic vaping device, the cartridge assembly formed from automated assembly compatible parts, the cartridge assembly comprising:

a container assembly including a container and a heater coil, the heater coil surrounding a wick in an airflow space of the container, the entire coil portion of the heater coil located inside the container and the heater coil configured to heat liquid on the wick to generate a vapor;

a liquid storage space in liquid communication with the wick;

an outer post; and

an inner post disposed in the outer post, the container on the inner post, and the inner post and the outer post supporting conductors electrically connected to heater coil leads of the heater coil that are held in location notches of the container, the conductors configured to electrically connect the heater coil leads with leads of the battery of the battery portion via the inner post and the outer post, the conductors isolated from the liquid storage space of the cartridge assembly.

2. The cartridge assembly of claim 1, wherein the container configured to reduce exposure of the conductors to air flow in the airflow space thereof and heat generated by the heater coil and the container configured to reduce exposure of the liquid storage space to heat generated by the heater coil.

3. The cartridge assembly of claim 1, wherein the inner post includes chamfers at locations near the heater coil such that heat generated by the heater coil received by the inner post is reduced.

4. The cartridge assembly of claim 1, wherein the inner post includes orientation fingers which are arranged so as to orient the inner post disposed in the outer post and streamline the assembly process thereof.

5. The cartridge assembly of claim 1 comprising an isolated tube disposed on the inner post, the isolated tube between the inner post and the conductors.

6. The cartridge assembly of claim 1, wherein the cartridge assembly is disposable.

7. The cartridge assembly of claim 1, further comprising:

a sleeve disposed above the container, the sleeve forming a portion of the airflow space of the cartridge assembly, which is in fluid communication with the airflow space of the container.

8. The cartridge assembly of claim 1, wherein the cartridge assembly includes a thread which is configured to connect the cartridge assembly to the battery portion.

9. The cartridge assembly of claim 8, wherein the thread surrounds the outer post, and an insulating ring electrically isolates the post from the thread such that an electrical circuit can be formed between the cartridge assembly and the battery portion.

10. An electronic vaping device comprising:

the cartridge assembly of claim 1 and

a battery portion including a battery configured to supply power to the heater coil of the cartridge assembly.

11. The electronic vaping device of claim 10, wherein the battery portion further comprises:

a controller; and

a flow sensor, the flow sensor configured to initiate the supply of power from the battery to the heating element when the flow sensor senses air flow through the electronic vaping device.
