Atomizer Venting Structure for Stable Liquid Supply
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing atomizers face issues with reduced liquid supply capacity due to negative pressure buildup in the liquid storage tank, leading to dry burning and burn-out of the heating part, as external gas is not efficiently drawn in to balance pressure.
Innovation Solution
The atomizer design incorporates a sealing member with a protrusion and support part that forms a ventilation passage, allowing external gas to directly enter the liquid storage tank through a mist outlet passage, enhancing liquid supply capacity and preventing negative pressure buildup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the liquid storage tank is designed as a closed structure to avoid liquid leakage, then liquid leakage is prevented, but negative pressure builds up when liquid is consumed, reducing liquid supply capacity
Solution Approach 1:
The sealed space is segmented into two functional zones: the liquid storage tank for liquid containment and the gas balancing chamber for pressure regulation. This segmentation allows the system to maintain sealing for leakage prevention while providing a dedicated space for gas accumulation to balance negative pressure, thus resolving the contradiction between reliability and productivity.
Solution Approach 2:
The gas balancing chamber acts as an intermediary between the liquid storage tank and the external environment. It mediates the pressure balance by accumulating gas that enters through the ventilation passage, preventing direct pressure equalization that would compromise the sealed structure, thereby maintaining both leakage prevention and liquid supply capacity.
2Reliability
If external gas is directly sucked into the liquid storage tank to balance negative pressure, then gas pressure is balanced, but liquid discharge speed is seriously affected before gas entry, causing dry burning
Solution Approach 1:
The gas balancing chamber performs preliminary action by accumulating gas in advance through the ventilation passage before the liquid storage tank experiences severe negative pressure. This preliminary gas accumulation prevents the situation where liquid discharge speed drops before pressure balance occurs, thereby preventing dry burning while maintaining continuous liquid supply.
Solution Approach 2:
The gas balancing chamber provides beforehand cushioning by storing gas that enters through the ventilation passage, creating a pressure buffer that compensates for negative pressure buildup. This cushioning effect ensures that liquid discharge speed is maintained without interruption, preventing dry burning of the heating element.
3Productivity
If a ventilation passage is added to allow external gas entry, then gas pressure is balanced and liquid supply is improved, but the device structure becomes more complex
Solution Approach 1:
The support part of the sealing member is designed to simultaneously perform multiple functions: sealing the liquid storage tank and providing structural support for the ventilation passage. By merging these functions into a single component, the design adds the necessary ventilation capability while minimizing the increase in overall device complexity.
Solution Approach 2:
The sealing member is designed with multi-functionality, serving both as a sealing element and as a structural component that integrates the ventilation passage. This universal design approach allows the same component to address both leakage prevention and pressure balancing needs, reducing the need for additional separate parts and minimizing structural complexity.
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 design ensures consistent liquid supply to the heating part, preventing dry burning and improving the atomizer's operational efficiency by maintaining adequate gas pressure in the liquid storage tank.
Implementation Method 1
when the liquid in the liquid storage tank is consumed, the volume of the gas in the liquid storage tank increases, so that the gas pressure is reduced. The reduced gas pressure may prevent liquid from flowing out to the heating part through a liquid guide
Implementation Method 2
an atomization assembly for atomizing liquid and mixing the atomized liquid with gas to generate aerosol

AI summary
An atomizer includes: a liquid cup provided with a mist outlet; an atomization assembly including an atomization tube, a liquid guide part, and a heating part disposed inside the liquid guide part, the atomization tube being sleeved on an outer peripheral side of the liquid guide part and having a first end connected with the mist outlet and a second end provided with a liquid inlet; and a sealing member including a support part and a protrusion. The support part abuts against an inner wall of the liquid cup. The support, the liquid cup and the atomization tube forms a liquid storage tank. The protrusion extends into the liquid guide part from an end of the liquid guide part away from the mist outlet. The support part is provided with at least one ventilation passage for connecting the liquid storage tank with atmosphere.
