Benefits of technology

[0002]When jetting a fluid onto a heated surface it is highly desirable for 100% of the fluid to vaporize so that liquid is not discharged from the vaporizing device. The problem lies in that the vaporizing heater must be small enough to heat up extremely quickly, but yet has enough surface area to catch all fluid and fluid droplets that are being ejected onto the heating element. A typical metal foil heating element has a smooth surface with minimal liquid/heater interface which is due to a low surface roughness of the heating element surface. Accordingly, some of the fluid droplets impinging on th

Embodiment Construction

[0023]The disclosure is directed to a vaporization device 10 as shown in FIGS. 1 and 2 and heating elements therefor as shown in FIGS. 3-8. Such devices 10 may be used for a wide variety of applications wherein a liquid is ejected onto a heating element to provide a vapor stream as described in more detail below. Such devices 10 are typically hand held devices such as electronic cigarettes that have a mouthpiece 12 for inhaling vapors generated by the device 10. The mouthpiece 12 includes a conduit 14 for flow of vapors out of the device 10. The main components of the device 10 include a housing body 16, a removable cartridge cover 18, a removable fluid supply cartridge 20, an ejection head 22 associated with the fluid supply cartridge 20, and a heating element 24 and holder therefor 26 for vaporizing fluid ejected from the ejection head 22. Other components associated with the vaporization device 10 include a rechargeable power supply 28, a main circuit board 30, and a vaporization...

Abstract

A heating element for a vaporizing device, a vaporizing device containing the heating element, and a method for vaporizing fluid ejected by an ejection head. The heating element includes a conductive material deposited onto an insulative substrate, a protective layer deposited onto the conductive layer, and a porous layer having a porosity of at least about 50% deposited onto the protective layer. The heating element has an effective surface area (ESA) for fluid vaporization that is greater than a planar surface area defined by dimensions of the heating element so that a fluid contact surface of the heating element is greater than the planar surface area of the heating element.

Description

TECHNICAL FIELD[0001]One of the applications of a fluidic ejection device is to jet a solution onto to another device where a secondary function may be performed. A common secondary function is to vaporize a solution using a heater such that the contents of the solution can be vaporized so as to deliver the solution as a gaseous substance. Applications of such technology include, but are not limited to, metering and vaporizing device for electronic cigarettes, vapor therapy, gaseous pharmaceutical delivery, vapor phase reactions for micro-labs, and the like. A problem associated with such devices is efficient vaporization of the fluid. This document discloses improved heating elements and methods for improving the vaporization efficiency of heating elements for vaporization devices.BACKGROUND AND SUMMARY[0002]When jetting a fluid onto a heated surface it is highly desirable for 100% of the fluid to vaporize so that liquid is not discharged from the vaporizing device. The problem lie...
