FILLED RESONANT CAVITY FOR OPTIMIZED DIELECTRIC HEATING - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240049794 titled 'FILLED RESONANT CAVITY FOR OPTIMIZED DIELECTRIC HEATING
Simplified Explanation
The abstract describes an aerosol-generating device that uses radio-frequency electromagnetic radiation to heat a substrate and generate an aerosol. The device includes an electromagnetic field generator, a resonant chamber, and a filling material.
- The electromagnetic field generator produces radio-frequency electromagnetic radiation with a specific frequency composition.
- The resonant chamber has a peripheral wall that is opaque to the radio-frequency electromagnetic radiation.
- The filling material is located inside the resonant chamber and encloses a substrate cavity where the aerosol-forming substrate is placed.
- The electromagnetic field generator is connected to the resonant chamber to transmit the generated radio-frequency electromagnetic radiation into the resonant chamber.
- The filling material has a relative permittivity greater than one, indicating its ability to store electrical energy.
Potential Applications:
- This technology can be used in the field of aerosol science and engineering for various applications such as inhalation drug delivery systems, electronic cigarettes, and air fresheners.
- It can also be applied in industries that require the generation of aerosols for testing purposes, such as pharmaceutical, chemical, and environmental industries.
Problems Solved:
- The device provides a controlled and efficient method for generating aerosols by heating the substrate using radio-frequency electromagnetic radiation.
- The resonant chamber's opaque wall prevents the radiation from escaping, ensuring that the generated aerosol is contained within the device.
- The filling material with a relative permittivity greater than one helps in maintaining a stable and consistent heating environment within the substrate cavity.
Benefits:
- The device offers precise control over the generation of aerosols, allowing for accurate dosing and delivery of substances.
- It provides a more efficient and reliable method compared to traditional heating techniques.
- The resonant chamber design ensures the safety of users by containing the aerosol within the device.
- The use of radio-frequency electromagnetic radiation allows for faster and more uniform heating of the substrate.
Overall, this patent application describes an innovative aerosol-generating device that utilizes radio-frequency electromagnetic radiation to heat a substrate and generate aerosols with improved control and efficiency.
Original Abstract Submitted
an aerosol-generating device is provided for heating an aerosol-forming substrate to generate an aerosol, the aerosol-generating device including: an electromagnetic field generator configured to generate radio-frequency (rf) electromagnetic radiation having a predetermined frequency composition; a resonant chamber including a peripheral wall configured to be substantially opaque to rf electromagnetic radiation within the resonant chamber; and a filling arranged within an interior of the resonant chamber so as to circumscribe a substrate cavity defined within the resonant chamber, the substrate cavity being configured to receive the aerosol-forming substrate, the electromagnetic field generator being coupled to the resonant chamber so as to convey the rf electromagnetic radiation generated by the electromagnetic field generator to the resonant chamber, and the filling having a relative permittivity of greater than one.
