Solution Overview
Problem
Existing smoke generating devices cause heat shrinkage or collapse of the supporting section in cigarette filter rods due to high temperatures, affecting the smoking experience and taste, especially when using general-purpose utensils not designed for specific cigarette varieties.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the heating element is positioned close to the cigarette filter rod to enhance heating efficiency, then heat exchange effect is improved, but the supporting section material cannot withstand the high temperature causing heat shrinkage or collapse
Solution Approach 1:
The cigarette introduction pipe is divided into an upper duct and a lower duct that are detachably connected or fixed by adhesive. This segmentation allows the lower duct to be positioned close to the heating element for efficient heat exchange, while the upper duct remains at a safer distance from the high-temperature zone, preventing heat shrinkage of the supporting section.
Solution Approach 2:
The cigarette introduction pipe acts as an intermediary structure between the heating element and the cigarette filter rod. By positioning the lower duct close to the heating element while maintaining thermal isolation through the duct structure itself, it enables efficient heat transfer to the cigarette without directly exposing the supporting section to excessive temperatures that would cause shrinkage or collapse.
2Object-affected harmful factors
If the cigarette introduction pipe is divided into upper and lower ducts with heat insulation pads, then heat transfer to the supporting section is reduced, but device complexity increases
Solution Approach 1:
The cigarette introduction pipe is segmented into an upper duct and a lower duct that can be detachably connected or fixed by adhesive. This modular segmentation reduces heat transfer to the supporting section by creating thermal zones, while the segmented structure itself becomes a manageable solution to the complexity issue through standardized connection interfaces.
Solution Approach 2:
Heat insulation pads are incorporated into the cigarette introduction pipe structure, creating a composite construction that combines conductive and insulating materials. This allows the lower duct to be positioned close to the heating element for efficient heat exchange while the insulation pads prevent excessive heat from reaching the supporting section, reducing heat shrinkage without requiring complete structural redesign.
3Use of energy by moving object
If the air-mixing cavity diameter is greater than the first introduction hole diameter, then heat exchange efficiency is improved, but manufacturing precision requirements increase
Solution Approach 1:
The air-mixing cavity has a diameter greater than the first introduction hole, creating a localized expansion zone where air can mix and circulate more effectively. This local quality change enhances heat exchange efficiency by providing a larger volume for thermal interaction between the air and the heated cigarette, while the dimensional difference between the cavity and the hole is managed through standard manufacturing tolerances for the duct structure.

AI summary
The present disclosure relates to the field of novel cigarette smoking utensil, and in particular, to a smoke generating device with enhanced heat exchange effect. The smoke generating device includes: a cigarette introduction pipe (1); the cigarette introduction pipe (1) is disposed at the upper end of the smoke generating device, with a hollow tubular structure, its internal cavity is an air-mixing cavity (1D), which is divided into an upper duct (1F) and a lower duct (1J), and at least one heat insulation pad is disposed between the upper duct (1F) and the lower duct (1J). In the present disclosure, for the first time, the cigarette introduction pipe is designed with two separable parts-the upper and lower duct, the heat insulation pad performs relative heat insulation on the upper duct and the lower duct, further playing the role of reducing the heat transmitting from the lower heating cup and heating element to the upper part. Thus, the temperature of the upper duct in contact with the cigarette filter rod is lower, which greatly reduces heat shrinkage or collapse caused by the material of the supporting section of the cigarette filter rod in contact with the cigarette introduction pipe of the smoke generating device that cannot withstand high temperature of the heating body.
