Aerosol delivery device
The present disclosure provides an aerosol delivery device comprising a control device that is connectable with a cartridge and that can include one or more additional elements for improving one or both of visible indications of use to a user and resistance to infiltration of liquid into the control device. More particularly, the control device may include a light guide configured for transmitting to a window from a light source that is off-set from the window and a controller configured to direct a varying level of light from the light source. The control device may include one or more elements that are configured to limit infiltration of liquids into the control device and thus may be consider to be water-resistant or water-proof.
1. An aerosol delivery device comprising:
at least one wall defining an outer housing;
a window in the at least one wall, the window extending between a first end and a second end;
a light source positioned within the outer housing and being connectable to a power source; and
a control component configured to direct power at a variable level from the power source to the light source such that light emitted from the light source fills a quantity of the window, the quantity corresponding to the variable level of power delivered to the light source.
2. The aerosol delivery device of claim 1 , wherein the light source is offset from the window so as to be beyond one of the first end of the window and the second end of the window.
3. The aerosol delivery device of claim 1 , further comprising a light guide positioned within the outer housing and proximate the window, the light guide being of sufficient size to substantially fill the window and at least partially overlap with the light source, wherein the light emitted from the light source is transmitted through the light guide and fills the quantity of the window.
4. The aerosol delivery device of claim 3 , wherein the position of the light source and the position of the light guide is effective to achieve the light emitted from the light source and transmitted through the light guide to grow in a direction from one of the first end of the window and the second end of the window to the other of the first end of the window and the second end of the window as power delivered from the power source to the light source increases and to recede in reverse of the direction as power delivered from the power source to the light source decreases.
5. The aerosol delivery device of claim 1 , further including a pressure sensor configured to detect changes in pressure within the outer housing across a continuous pressure intensity range and provide signaling to the controller corresponding to the pressure intensity.
6. The aerosol delivery device of claim 5 , wherein the control component is configured to adjust the variable level of the power delivered from the power source to the light source in response to the signaling received from the pressure sensor.
7. The aerosol delivery device of claim 5 , wherein the power source and the control component are configured for connection with an atomizer.
8. The aerosol delivery device of claim 7 , wherein the control component is configured to direct power at a variable level from the power source to the atomizer in response to the signaling received from the pressure sensor.
9. The aerosol delivery device of claim 1 , further comprising a printed circuit board positioned within the outer housing, the light source being positioned on the printed circuit board.
10. The aerosol delivery device of claim 9 , wherein the control component is positioned on the same printed circuit board as the light source.
11. The aerosol delivery device of claim 3 , further comprising a sealing member positioned between the light guide and the at least one wall defining the outer housing.
12. The aerosol delivery device of claim 11 , wherein the sealing member is integral with the light guide.
13. The aerosol delivery device of claim 12 , wherein the light guide is formed of a translucent elastomeric material.
14. The aerosol delivery device of claim 1 , further comprising a liquid-resistive membrane positioned interior to the outer housing, the liquid-resistive membrane covering the window in the at least one wall.
15. The aerosol delivery device of claim 14 , wherein the liquid-resistive membrane is adhered to an interior surface of the at least one wall.
