An atomizer design featuring a core assembly with defined air-inlet and smoke-outlet passages, including at least one atomizing chamber and one cooling passage, where the cooling passage is spaced from the atomizing chamber to dissipate heat and reduce smoke temperature, comprising a heating assembly with an oil-absorbing element and heating wire, and additional components like an insulating element and conductive components for efficient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the core assembly heats the atomizing chamber to generate smoke, then the atomizing function is improved, but the temperature of the core assembly and smoke becomes too high, reducing stability and service life
Solution Approach 1:
The core assembly is divided into functionally independent segments: the atomizing chamber for heating and smoke generation, and the cooling passage for heat dissipation. This segmentation allows the heating function to operate at high temperature while the cooling function operates independently, resolving the contradiction between achieving sufficient atomizing temperature and maintaining reliability through temperature control.
Solution Approach 2:
Air serves as an intermediary cooling medium that flows through the cooling passage, absorbing excess heat from the core assembly and smoke without interfering with the atomizing process. This intermediary approach allows heat removal while maintaining the high temperature needed for effective atomization.
2Temperature
If the core assembly heats the atomizing chamber to generate smoke, then the atomizing function is improved, but the service life of the core assembly is reduced due to high temperature
Solution Approach 1:
The core assembly is divided into functionally independent segments: the atomizing chamber for heating and smoke generation, and the cooling passage for heat dissipation. This segmentation allows the heating function to operate at high temperature while the cooling function operates independently, resolving the contradiction between achieving sufficient atomizing temperature and maintaining reliability through temperature control.
Solution Approach 2:
The cooling passage is designed to cool the core assembly before and during the heating process, preventing excessive temperature accumulation that would reduce service life. This preliminary cooling action ensures the core assembly can sustain high-temperature operation for longer periods.
3Temperature
If the core assembly generates high temperature smoke during heating, then the atomizing efficiency is improved, but the risk of burning users is increased
Solution Approach 1:
Air serves as an intermediary cooling medium that flows through the cooling passage, absorbing excess heat from the core assembly and smoke without interfering with the atomizing process. This intermediary approach allows heat removal while maintaining the high temperature needed for effective atomization.
Solution Approach 2:
The harmful excess heat is extracted from the smoke through the cooling passage, separating the useful hot smoke for atomization from the harmful excessive temperature that causes burning risk. This extraction process reduces smoke temperature to safe levels while maintaining atomizing efficiency.
4Temperature
If a cooling passage is added to the core assembly, then the temperature control is improved, but the structural complexity of the core assembly increases
Solution Approach 1:
The cooling passage is merged with the existing core assembly structure, utilizing the same material and integration process as the atomizing chamber. This combining approach adds the cooling function without significantly increasing overall structural complexity, as both functions share the same structural framework.
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 atomizer effectively cools down the core assembly, enhancing stability and service life while preventing smoke burning by reducing the temperature of the smoke through air passage through the cooling passage, ensuring safer user experience.
Implementation Method 1
Air passing through the cooling passage may take away a part of heat so as to cool down the atomizer
Implementation Method 2
a part of air entering the atomizer passes through the cooling passage and then is further mixed with smoke generated by atomizing another part of air through the atomizing chamber, thus reducing the temperature of the smoke
