  • Publication number: 20190350265
    Abstract: The present disclosure provides a control body adapted for use in an electronic smoking article. The control body includes a shell and a coupler that is adapted to connect the control body to a cartridge of an electronic smoking article. The coupler further is adapted to communicate a pressure reduction within the coupler to a pressure reduction space in the shell. Also positioned within the shell is an electronic circuit board having a pressure sensor attached thereto. The electronic circuit board can be positioned to be parallel to a central axis of the shell. A first end of the pressure sensor can be isolated within the pressure reduction space, and a second end of the pressure sensor can be in communication with a normal pressure space within the shell. One or more light emitting diodes can be attached to the electronic circuit board. At least a portion of the coupler can be light transmissive so that light from the LED is visible through the coupler.

The control body includes a shell and a coupler that is adapted to connect the control body to a cartridge of an electronic smoking article. The coupler further is adapted to communicate a pressure reduction within the coupler to a pressure reduction space in the shell. Also positioned within the shell is an electronic circuit board having a pressure sensor attached thereto. The electronic circuit board can be positioned to be parallel to a central axis of the shell. A first end of the pressure sensor can be isolated within the pressure reduction space, and a second end of the pressure sensor can be in communication with a normal pressure space within the shell. One or more light emitting diodes can be attached to the electronic circuit board. At least a portion of the coupler can be light transmissive so that light from the LED is visible through the coupler.
