Solution Overview

Problem

Existing e-liquids with nicotine salts require complex preparation processes and cannot effectively meet the diverse satisfaction needs of users due to varying absorption rates in the respiratory system, particularly in the lung, where protonated forms are not absorbed.

Innovation Solution

A ceramic vaporization core with a porous body doped with a hydroxyl group-containing matrix, comprising specific ceramic powder and pore-forming agents, is designed to reduce nicotine protonation and control particle size for enhanced lung absorption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If e-liquids with nicotine salts are prepared to improve user satisfaction, then nicotine absorption in the lung is improved, but the preparation process becomes complex and has technological barriers

Engineering Contradiction:
Improvenicotine absorption efficiencyVSAvoidpreparation process complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces a ceramic vaporization core as an intermediary component that contains basic substances (such as calcium carbonate, magnesium carbonate, or aluminum hydroxide) to neutralize nicotine protonation in situ. This mediator approach allows the system to achieve low protonation levels without requiring complex pre-preparation of nicotine salts, thereby improving absorption efficiency while simplifying the overall process

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent changes the pH parameter of the vaporization environment by incorporating basic substances in the ceramic core. This parameter change (increasing pH to reduce protonation) is achieved through material selection rather than complex chemical preparation, allowing nicotine to remain in free-base form for better lung absorption while avoiding the technological barriers of nicotine salt preparation

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If nicotine is delivered in protonated forms to meet user requirements, then diverse user requirements can be met, but nicotine cannot enter blood through the biofilm in the lung

Engineering Contradiction:
Improveuser requirement satisfactionVSAvoidnicotine absorption in lung
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent applies local quality by creating different chemical environments in different parts of the vaporization system. The ceramic core contains basic substances that locally increase pH and reduce protonation at the vaporization interface, ensuring nicotine is in free-base form for lung absorption. This localized chemical modification allows the system to maintain adaptability for different users while ensuring reliable lung absorption

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

Basic substances in the ceramic core act as intermediaries that facilitate nicotine conversion from protonated to free-base form. This intermediary mechanism ensures that regardless of the initial nicotine form in the e-liquid, the vaporization process produces free-base nicotine suitable for lung absorption, thereby maintaining both user requirement satisfaction and absorption reliability

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

The present invention relates to a vaporizer and a ceramic vaporization core thereof, and a method for fabricating the ceramic vaporization core. The ceramic vaporization core includes a porous body and a heating body disposed on the porous body. The porous body includes at least one porous ceramic layer doped with hydroxyl group-containing matrix. The configuration of the at least one porous ceramic layer doped with hydroxyl group-containing matrix allows hydrogen ions in nicotine in e-liquid that passes through the porous body and has not been vaporized to react with hydroxyl groups, to reduce the degree of protonation of nicotine in e-liquid, thereby improving the absorption degree of nicotine in the lung and improving user experience.
