Atomizer Housing Dimensions for Low Draw Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic cigarette cartridges are thick and have an unreasonable size design, leading to poor user experience due to high draw resistance and inability to be flattened, resulting in suboptimal smoke production and handling.
Innovation Solution
An atomizer design with a housing that allows for increased air volume in the atomizing chamber, ensuring pressure balance between the E-liquid storage and atomizing chambers, featuring a gas inlet on the side surface and an atomizing core fixing member with a ventilation channel, optimizing dimensions to achieve an ultra-thin design while maintaining efficient atomization and low draw resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the cartridge is flattened to reduce thickness, then the portability and user experience are improved, but the air volume in the atomizing chamber decreases, causing poor atomization and high draw resistance
Solution Approach 1:
The E-liquid storage chamber is nested within the housing structure, with the atomizing chamber positioned around it. The atomizing core fixing member is inserted into the atomizing chamber, creating a nested arrangement where components are arranged concentrically rather than linearly. This nesting allows the atomizing chamber to maintain sufficient air volume while the overall cartridge thickness is reduced through optimized spatial arrangement.
Solution Approach 2:
The design transitions from a linear arrangement of components to a three-dimensional configuration where the atomizing chamber surrounds the E-liquid storage chamber in a radial direction. The gas inlet is positioned on the side surface of the housing, introducing air from the lateral dimension rather than from the top or bottom, which increases air volume without increasing cartridge thickness.
2Length of moving object
If the cartridge thickness is reduced, then the device becomes more portable, but the assembly efficiency of the atomizing core decreases due to space constraints
Solution Approach 1:
The atomizing core assembly is segmented into distinct components: the atomizing core itself, the atomizing core fixing member, and the housing. The fixing member is designed as a separate component that can be independently assembled into the housing, allowing for modular assembly even in the constrained thickness space. This segmentation enables efficient assembly by allowing components to be pre-assembled and then integrated into the final structure.
3Length of moving object
If the dimensions are optimized for ultra-thin design, then the user experience during handling is improved, but the pressure balance between chambers becomes difficult to maintain
Solution Approach 1:
The ventilation channel is designed to create equipotential pressure conditions between the E-liquid storage chamber and the atomizing chamber. By providing a direct communication path through the atomizing core fixing member, the design ensures that pressure differences between the two chambers are minimized, allowing both chambers to operate at nearly equal pressure levels even in the ultra-thin configuration.
4Volume of stationary object
If the atomizing chamber volume is increased to improve atomization, then the smoke production quality is improved, but the cartridge thickness increases, reducing portability
Solution Approach 1:
The atomizing chamber is designed to extend in the radial direction around the E-liquid storage chamber rather than only in the axial direction. This three-dimensional arrangement allows the atomizing chamber to achieve sufficient volume for good atomization while the cartridge thickness remains controlled. The gas inlet on the side surface further contributes to this by introducing air from the lateral dimension, maximizing the use of available space.

AI summary
An atomizer 100 for an electronic cigarette includes an E-liquid storage chamber 11, an aerosol passage 12, an atomizing chamber 13 and an inspiratory mouth 141 arranged on a housing 1. At least one gas inlet (1521) is located on a side surface of the housing. The dimensions of the housing in a thickness direction (D), a length direction L, and a width direction W satisfy L>W≥D, 5≤L/D≤9, and 2≤W/D≤5. An atomizing core fixing member 2 is provided with an atomizing core 3 that communicates with the E-liquid storage chamber and the atomizing chamber respectively. At least one atomization guide channel (21) bringing the aerosol passage and the atomizing chamber into communication is defined between the atomizing core fixing member and an inner wall of the housing. The atomizer has an ultrathin design, and ensures a pressure balance between the E-liquid storage chamber and the atomizing chamber.
