Atomizer With Nested Tubes For E-Cigarette Storage

The patent implements nesting by placing the metal inner tube inside the plastic outer tube, creating a concentric dual-tube structure. The metal inner tube defines an air inlet passage while the space between the inner and outer tubes forms the liquid storage chamber, effectively utilizing the annular space for e-liquid storage without increasing overall device volume.

The patent employs a thin-walled metal inner tube that provides sufficient structural strength while minimizing the occupation of liquid storage space. The metal inner tube is designed with optimized wall thickness to balance mechanical strength requirements with the need to maximize the annular liquid storage chamber volume between the inner and outer tubes.

The patent merges the connection function into the integral structure by designing the metal inner tube to be directly connected to the plastic outer tube through an integrated forming process. The connecting portion is formed as an integral part of the plastic outer tube, eliminating the need for separate connecting components and reducing overall device complexity while maintaining connection reliability.

The patent transforms the conventional single-tube structure into a nested dual-tube configuration where the metal inner tube is positioned inside the plastic outer tube. This nesting arrangement creates an annular liquid storage chamber that significantly increases e-liquid capacity while maintaining relatively simple manufacturing processes and structural design.
