Abstract
A device and method for converting a consumable into an aerosol with high heat without burning the consumable by packaging the consumable containing an internal susceptor inside a housing. A first end of the housing can be capped with an end cap and a second end of the housing can have a mouthpiece. The housing containing the consumable and the susceptor can be placed inside a case with an inductive heating element configured to heat the susceptor. Heating the susceptor results in the consumable being released as an aerosol for inhalation.
Core Innovation
The invention relates to a heat-not-burn device for generating an inhalable aerosol using a consumable-containing unit comprising compressed powder and a susceptor embedded within the consumable-containing unit. The susceptor is heated using an inductive heating element to temperatures from 550 degrees C. to 800 degrees C. while enclosed in a housing having a first end and a second end opposite the first end.
The device includes an end cap at the first end of the paper tube or housing and a mouthpiece at the second end of the paper tube or housing, with the consumable-containing unit and susceptor arranged to be heated within the package. The temperature range and the inductive heating element configuration are used to generate an inhalable aerosol from the consumable-containing unit containing the embedded susceptor.
In manufacturing, a powder form of a consumable-containing unit is compressed around a susceptor, placed into a housing having a first end and a second end, and assembled with an end cap and a mouthpiece. The assembled housing is placed into a case comprising an inductive heating element configured to heat the susceptor to temperatures from 550 degrees C. to 800 degrees C., such that a device for generating an inhalable aerosol is manufactured.
Claims Coverage
The independent claims cover four device/manufacturing approaches, centered on compressed powder consumable-containing units with embedded susceptors heated inductively to a defined temperature range (550 degrees C. to 800 degrees C.), using end cap and mouthpiece interfaces, with variations in how the consumable and package are encased and controlled. The independent claims are clm-00001, clm-00002, clm-00008, and clm-00016.
Embedded susceptor in compressed powder consumable-containing unit
A consumable-containing unit comprising compressed powder, with a susceptor embedded within the consumable-containing unit.
Paper tube encasing with end cap and mouthpiece
A paper tube encasing the consumable-containing unit and the susceptor, the paper tube comprising a first end and a second end opposite the first end; an end cap at the first end of the paper tube; and a mouthpiece at the second end of the paper tube.
Inductive heating element heating embedded susceptor to 550–800 degrees C.
An inductive heating element configured to heat the susceptor to temperatures from 550 degrees C. to 800 degrees C.
Inductive heating element within housing encasing consumable unit
A housing encasing the consumable-containing unit and the susceptor, the housing comprising a first end and a second end opposite the first end; an end cap at the first end of the housing; a mouthpiece at the second end of the housing; and an inductive heating element in the housing, the inductive heating element configured to heat the susceptor to temperatures from 550 degrees C. to 800 degrees C.
Controller controlling the inductive heating element
A controller to control the inductive heating element.
Compressed consumable-containing unit with housing and inductive heating element
A compressed consumable-containing unit comprising a compressed powder, with a susceptor embedded within the compressed consumable-containing unit; a housing encasing the compressed consumable-containing unit and the susceptor, the housing comprising a first end and a second end opposite the first end; and an inductive heating element inside the housing, the inductive heating element configured to heat the susceptor to temperatures from 550 degrees C. to 800 degrees C.
Inductive-heating-based manufacturing of inhalable aerosol device
Manufacturing an inhalable aerosol device by compressing a powder form of a consumable-containing unit around a susceptor; placing the consumable-containing unit and the susceptor into a housing having a first end and a second end; placing an end cap at the first end of the housing; placing a mouthpiece at the second end of the housing; and placing the housing into a case having an inductive heating element configured to heat the susceptor to temperatures from 550 degrees C. to 800 degrees C., whereby the device for generating an inhalable aerosol is manufactured.
Across the independent claims, the main inventive coverage centers on a consumable-containing unit with compressed powder and an embedded susceptor, an inductive heating element configured to heat the susceptor to 550 degrees C. to 800 degrees C., and assembly features including an end cap and a mouthpiece, with variations on whether the encasing is a paper tube or a housing and how the device is manufactured in a case.
Stated Advantages
Quick heat/cool.
Power conservation.
Reduced burnt flavor/toxin generation compared to prior HNB devices.
