US 11,399,574 B2 · Aerosol-generating apparatus, thermal distribution casing, and related methods

Abstract

An aerosol-generating apparatus includes a mouthpiece, an aerosolizing thermal reactor, and an air preheating passage. The aerosolizing thermal reactor has an air inlet upstream of an aerosol outlet, and includes an aerosolizable substance chamber and a thermal distribution casing. The thermal distribution casing surrounds the aerosolizable substance chamber and includes a laminate material with an at least three-layer construction including a metal middle layer between a metal outer layer and a metal inner layer. The thermal conductivity of the metal inner layer is at least double that of each of the metal outer and inner layers. The air preheating passage is located downstream of the air inlet and upstream of the aerosolizable substance chamber, and surrounds the aerosolizable substance chamber. The air preheating passage is defined by an air gap between the chamber outer wall and the metal inner layer.

Dependent claims

A thermal distribution casing for an aerosol-generating apparatus body, the thermal distribution casing comprising:

a sidewall extending longitudinally from a sidewall proximal end to a sidewall distal end, the sidewall comprising a multi-layer construction, the multi-layer construction having at least a first metal layer and a second metal layer,
the first metal layer composed of a first metal material having a first thermal conductivity, the second metal layer composed of a second metal material having a second thermal conductivity, and the first thermal conductivity being at least double of the second thermal conductivity;
a distal end portion transversely covering the sidewall distal end, the distal end portion comprising a sensory temperature indicator,
the sidewall and distal end portion together defining a body receiving chamber for an aerosol generating apparatus body, the body receiving chamber extending longitudinally from a body entry port at the sidewall proximal end to a chamber distal end proximate the distal end portion;
wherein the sensory temperature indicator has a set point temperature at which the sensory temperature indicator generates an audible alert.
