Permeable element based vaporization process and device
11707090 · 2023-07-25 ·

The present invention discloses an atomizer. The atomizer includes a concentrate reservoir volume that is in fluid communication with a concentrate vaporization assembly. The concentrate vaporization assembly includes a frit adapted to absorb concentrate from the concentrate reservoir volume. The concentrate vaporization assembly further includes a heating element adapted to heat the frit and absorbed concentrate. The atomizer further includes a vapor collection and discharge assembly including a vapor accumulation chamber in fluid communication with the frit and a vapor evacuation channel in fluid communication with the vapor accumulation chamber and in fluid communication with an egress port. The heating element is activated by a user control of a switch on a battery, which causes the concentrate contained within the frit filter to vaporize, and the user inhales resulting vapor by inhaling at the egress port of the vapor evacuation channel.

Evaporator

An evaporator for an aerosol generating device is described. The evaporator comprises a heating body (101) comprising a plurality of channels (102) arranged through the heating body between an inlet surface (103) and an outlet surface (104). The channels are configured to transport liquid from the inlet surface through the heating body by capillary action. The heating body comprises electrically conductive material (120) and the evaporator further comprises circuitry (116) for providing a current through the electrically conductive material to provide resistive heating of the heating body to evaporate a liquid passing through the channels. The heating body and circuitry are configured to provide a positive temperature gradient across the heating body from the inlet surface to the outlet surface.
