Atomizer Liquid Channel Sealing for On-Demand Aerosol Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic vaporization devices fail to prevent the liquid substrate from being transferred to the vaporization assembly before use, leading to potential leakage and inefficiencies.
Innovation Solution
A vaporizer design with a housing containing a liquid storage compartment divided into first and second compartments, a liquid channel, a fluid-permeable heating element, and a sealing member with a blocking arm that selectively opens and closes the liquid channel, controlled by an electrical contact that moves longitudinally to manage liquid flow and power distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the liquid storage compartment is continuously open to the vaporization assembly, then liquid substrate can be readily supplied to the heating element, but liquid leakage and premature transfer occur before use
Solution Approach 1:
The blocking arm is positioned to close the liquid channel before the device is activated. The electrical contact is pre-positioned to drive the blocking arm open only when power is applied, ensuring liquid substrate is supplied to the vaporization assembly only at the appropriate time and preventing premature transfer or leakage
Solution Approach 2:
The blocking arm transitions from a static closed position to an open position when the electrical contact is actuated. This dynamic control mechanism allows the liquid channel to be sealed during storage and transport, then opened on-demand during operation, resolving the contradiction between continuous supply readiness and leakage prevention
2Use of energy by moving object
If the electrical contact remains continuously connected to the heating element, then power is always available for vaporization, but unintended heating and liquid evaporation occur
Solution Approach 1:
The electrical contact is pre-positioned in a disconnected state before use. The system is designed so that power connection to the heating element occurs only when the user intentionally activates the device, preventing unintended heating and evaporation while ensuring power is available when needed
Solution Approach 2:
The movable electrical contact acts as an intermediary between the power source and the heating element. It controls the timing of power delivery by making or breaking the electrical connection based on device activation, preventing direct continuous power application that would cause harmful evaporation
3Productivity
If the liquid channel remains open for easy liquid flow, then vaporization efficiency is maintained, but liquid substrate leaks to unintended areas
Solution Approach 1:
The blocking arm is positioned to seal the liquid channel before the device is activated. When power is applied, the electrical contact drives the blocking arm to open the channel, ensuring liquid flows only when intended for vaporization, thus maintaining efficiency while preventing leakage to unintended areas
Solution Approach 2:
The blocking arm is extracted as a separate controllable element that can be selectively positioned to open or close the liquid channel. This allows the channel to be sealed during non-use periods, preventing leakage, while enabling efficient liquid flow to the vaporization assembly when the blocking arm is actuated open

AI summary
This application provides a vaporizer and an electronic vaporization device. The vaporizer includes: a housing; a liquid storage compartment, storing a liquid substrate, and having a first compartment and a second compartment; a liquid channel, located between the first compartment and the second compartment, to provide a flow path for liquid in the first compartment to flow to the second compartment; and a fluid-permeable heating element, in fluid communication with the second compartment, and configured to heat and vaporize the liquid substrate to generate an aerosol; a sealing member, having a blocking arm, where the blocking arm closes a liquid channel when in a first configuration, and opens a liquid channel when in a second configuration; and an electrical contact, movable in a longitudinal direction of the housing, to drive the blocking arm to be configured from the first configuration toward the second configuration. Using the vaporizer, a user can move the electrical contact to drive the blocking arm to open the liquid channel.
