Abstract
Percussive ignition systems and heat packages incorporating percussively igniter systems capable of being activated by inhalation are disclosed.
Claims45
An inhalation actuated percussive ignition system comprising:
- a housing defining an airway, wherein the housing comprises at least one air inlet and a mouthpiece having at least one air outlet;
- an airflow sensitive actuator coupled to the airway;
- and
- a mechanism coupled to the airflow sensitive actuator configured to activate a percussive igniter;
- wherein the percussive igniter is activated by an airflow in the airway produced by inhaling through the mouthpiece.
2 more elements
A method for activating a percussive igniter, comprising the steps of:
- providing an inhalation actuated percussive ignition system, comprising:
- a housing defining an airway, wherein the housing comprises at least one air inlet and a mouthpiece having at least one air outlet;
- an airflow sensitive actuator coupled to the airway;
- and
- a mechanism coupled to the airflow sensitive actuator configured to activate a percussive igniter;
- inhaling through the mouthpiece to generate an air flow in the airway;
- actuating the airflow sensitive actuator;
- and
- activating the percussive igniter.
6 more elements
An inhalation actuated percussive ignition system comprising:
- a housing defining an airway, wherein the housing comprises at least one air inlet and a mouthpiece having at least one air outlet;
- an airflow sensitive actuator coupled to the airway;
- and
- a mechanism coupled to the airflow sensitive actuator configured to activate a percussive heating element;
- wherein the percussive heating element comprises an enclosure comprising a region capable of being deformed by a mechanical impact;
- an anvil disposed within the enclosure;
- a percussive initiator composition disposed within the enclosure, wherein the initiator composition is configured to be ignited when the deformable region of the enclosure is deformed;
- and
- a fuel disposed within the enclosure configured to be ignited by the initiator composition;
- and
- wherein the percussive heating element is activated by an airflow in the airway produced by inhaling through the mouthpiece.
8 more elements
An inhalation actuated heating system, comprising:
- a housing defining an airway, wherein the housing comprises at least one air inlet and a mouthpiece having at least one air outlet;
- an airflow sensitive actuator coupled to the airway;
- a mechanism coupled to the airflow sensitive actuator configured to activate a percussive igniter;
- and
- a heating element comprising a fuel, wherein the fuel is configured to be ignited by the percussive igniter;
- wherein the percussive igniter is activated by an airflow in the airway produced by inhaling through the mouthpiece.
3 more elements
A method of actuating a heating element, comprising:

2 more elements
A method of producing a condensation aerosol of a substance, comprising:
- providing an inhalation actuated heating element comprising:
- a housing defining an airway, wherein the housing comprises at least one air inlet and a mouthpiece having at least one air outlet;
- an airflow sensitive actuator coupled to the airway;
- a mechanism coupled to the airflow sensitive actuator configured to activate a percussive igniter;
- a heating element disposed within the airway, wherein the heating element comprises a fuel disposed within the enclosure, and a percussive igniter disposed within the enclosure and configured to ignite the fuel;
- and
- a substance disposed on at least a portion of the exterior of the enclosure;
- inhaling through the mouthpiece to generate an airflow in the airway;
- actuating the airflow sensitive actuator;
- activating the percussive igniter;
- igniting the fuel;
- and
- vaporizing the substance disposed on exterior of the enclosure to form an aerosol comprising the substance in the airway.
