Abstract

A heating device for a smoke-free cigarette is substantially made up of a liquid container and/or a reaction element, separated from one another by a destructible seal and filled with substances, the mixing of which triggers an exothermic reaction. A pin composed of heat-conductive plastic or metal is provided on the reaction element, which pin interacts with the seal, and onto which a profile body is set. The profile body is produced from an earth alkali metal, calcium chloride, calcium chloride, magnesium sulfate, sodium hydroxide or calcium oxide.

Claims

1. A smoke-free cigarette comprising:

a tubular cigarette body;

a mouthpiece inserted in the cigarette body, the mouthpiece having a membrane;

a depot situated in the cigarette body, the depot being filled with nicotine and a carrier substance;

a heating apparatus; and

an activation device for triggering the heating apparatus, the activation device comprising a mandrel;

wherein the heating apparatus comprises

a liquid container filled with a substance, and

a reaction element produced from a substance;

wherein mixing of these substances triggers an exothermic reaction, and the substances are separated from one another by means of at least one destructible seal;

wherein a pin composed of heat-conductive plastic or metal is provided on the reaction element, the pin interacting with the seal, and onto the pin a profile body being set;

wherein the profile body is produced from an earth alkali metal, calcium chloride, calcium chloride, magnesium sulfate, sodium hydroxide or calcium oxide;

wherein the liquid container comprises a stop;

wherein the reaction element has a longitudinal center line and comprises a face-side end and a tip shaped as a conical stump;

wherein the pin extends coaxially to the longitudinal center line of the reaction element and passes through the profile body completely and extends through the tip into the depot;

wherein the liquid container is pushable into the reaction element so that the stop of the liquid container makes contact with the face-side end of the reaction element;

wherein the pin is configured to penetrate the seal by pushing the liquid container into the reaction element; and

wherein the reaction element is axially displacable in the cigarette body, and is configured to be axially displaced if pressure is exerted on the liquid container after the stop makes contact with the face-side end of the reaction element to bring about displacement of the depot in such a way that the mandrel passes through the membrane in the mouthpiece.

2. The smoke-free cigarette according to claim 1, wherein the liquid container is filled with water.

3. The smoke-free cigarette according to claim 1, wherein the reaction element is filled with calcium chloride and a fat derivative.

4. A smoke-free cigarette comprising:

a tubular cigarette body;

a depot situated in the cigarette body, the depot being filled with nicotine and a carrier substance;

a heating apparatus; and

an activation device for triggering the heating apparatus, the activation device comprising an accommodation;

wherein the heating apparatus comprises

a liquid container disposed in the accommodation and filled with a substance and

a reaction element that is produced from a substance;

wherein mixing of these substances triggers an exothermic reaction, and the substances are separated from one another by means of at least one destructible seal;

wherein a pin composed of heat-conductive plastic or metal is provided on the reaction element, the pin interacting with the seal, and onto the pin a profile body being set; and

wherein the profile body is produced from an earth alkali metal, calcium chloride, calcium chloride, magnesium sulfate, sodium hydroxide or calcium oxide.
