Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ultrasonic high-frequency atomizing electronic cigarettes suffer from reduced atomizing efficiency and smoke production due to disordered air flow, tobacco tar accumulation, heat transfer to the shell, and condensation of smoke in metal air outflow passages, which affects user experience.
Innovation Solution
An atomizer design featuring an air guide structure that directs air to flow over the atomizing cotton, a tobacco tar guide body with closely attached atomizing cotton, and a thermal insulation liner tube to prevent heat transfer and condensation, ensuring efficient atomization and improved smoke quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If air passes through the air inflow passage to the atomizing surface, then air supply is provided for atomization, but the air flow becomes disordered causing most air to flow away directly without participating in atomization, greatly reducing atomizing efficiency and smoke amount
Solution Approach 1:
The patent introduces atomizing cotton as an intermediary substance between the air inflow passage and the atomizing surface. The cotton guides the air flow to move along the atomizing surface, ensuring that air participates in the atomization process rather than flowing away directly. This intermediary structure resolves the contradiction by transforming disordered air flow into controlled flow that enhances both atomizing efficiency and smoke production.
2Productivity
If cold air mixes with atomized smoke, then air supply is maintained, but the temperature of the smoke entering the mouth is lowered, resulting in poor mouthfeel
Solution Approach 1:
The patent changes the flow path geometry from direct vertical flow to a horizontal flow along the atomizing surface. By guiding air to flow along the surface where atomization occurs, the air mixes with hot vaporized substances during the atomization process itself, heating the air before it reaches the user. This dimensional change in flow path resolves the temperature contradiction.
3Ease of operation
If the surface of the atomizing sheet is not closely attached to the tobacco tar guide body, then tobacco tar can be supplied, but tobacco tar accumulates on the atomizing sheet surface especially when not used for long periods, causing difficulty in atomization and reduced smoke discharge
Solution Approach 1:
The patent implements preliminary action by having atomizing cotton closely attached to the atomizing surface, creating a pre-positioned structure that prevents tobacco tar accumulation before it occurs. The cotton acts as a barrier that guides tobacco tar flow and prevents it from accumulating on the atomizing sheet surface during idle periods, ensuring consistent atomization performance.
4Strength
If the air outflow passage is made of metal, then structural strength is provided, but the atomized smoke condenses after flowing a certain distance, reducing smoke amount and allowing condensed tobacco tar to be sucked into the mouth
Solution Approach 1:
The patent changes the material parameter of the air outflow passage from metal to non-metallic materials with low thermal conductivity and non-polar characteristics. This parameter change prevents heat transfer that would cause condensation, maintaining smoke in vapor form throughout the passage and preventing tobacco tar condensation that could be harmful to users.
5Productivity
If the atomizing sheet is heated for atomization, then atomizing function is achieved, but heat is easily transferred to the shell through the air outflow passage, causing the shell to become very hot
Solution Approach 1:
The patent introduces thermal insulation material as an intermediary between the atomizing sheet and the shell. This intermediary layer blocks heat transfer from the heated atomizing sheet to the shell, preventing the shell from becoming hot while maintaining efficient atomization. The insulation material acts as a thermal barrier that resolves the heat transfer contradiction.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enhances atomizing efficiency, increases smoke production, improves smoke concentration and mouthfeel, and prevents tobacco tar accumulation and heat transfer to the shell, resulting in a more satisfying user experience.
Implementation Method 1
transfers tobacco tar in a tobacco tar cavity to an atomizing sheet through tobacco tar storage cotton, and then atomizes the tobacco tar by high-frequency oscillation
Implementation Method 2
The heat generated by the atomizing sheet is easily transferred to a shell through the air outflow passage, causing the shell to be very hot
Implementation Method 3
the air guide passage is designed such that the air entering from the first air inflow passage can be guided to flow, therefore all the air can pass over, at a low level, the surface where the atomizing cotton is in contact with the atomizing sheet
Implementation Method 4
the atomizing cotton is of a hollow cylindrical structure, and the lower part of the air outflow pipe is inserted into the hollow cavity of the atomizing cotton
