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 method of assembling a cartomizer assembly of an electronic cigarette wherein the cartomizer assembly is formed from automated assembly compatible parts, the method comprising:

inserting an inner post into an outer post wherein a conductive strip is disposed therebetween; and

inserting a punch into a hole in the inner post wherein the punch removes a portion of the conductive strip so as to form conductors.

2. The method of claim 1, comprising aligning orientation fingers of the inner post into the outer post.

3. The method of claim 1, further comprising:

forming a container assembly, the container assembly formed by winding a heater coil around a wick, dropping the heater coil and wick into a container, and locating heater coil leads of the heater coil in location notches of the container by bending ends of the heater coil leads around an end of the container; and

putting the container assembly on the inner post wherein each heater coil lead electrically connects with a respective conductor.

4. The method of claim 3, further comprising disposing the container assembly, the inner post, and the outer post in a liquid storage area of a cartomizer assembly such that the wick is in liquid communication with liquid in the liquid storage area and the conductors are isolated from the liquid storage area.
