Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic cigarettes have fixed airflow holes, resulting in non-adjustable suction resistance, which cannot meet the diverse preferences of users.
Innovation Solution
An electronic cigarette with an air adjusting mechanism that includes a microphone starting switch, flow dividing piece, and air adjusting piece, allowing for adjustable suction resistance through the movement of the air adjusting piece within a guide groove, and utilizing clamping and elastic pieces for stable connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If an induction switch is used to realize automatic start and stop, then the electronic cigarette can be activated automatically, but the airflow holes become fixed and suction resistance becomes non-adjustable
Solution Approach 1:
The patent introduces a movable air adjusting piece that can be positioned at different locations within a guide groove to dynamically change the opening area of air holes. This allows the suction resistance to be adjusted according to user preferences while maintaining the automatic start-stop function through the induction switch.
Solution Approach 2:
The air adjusting mechanism is divided into separate components: the air adjusting piece, the guide groove, and the air holes in the flow dividing piece. This segmentation allows independent adjustment of air flow parameters without affecting the automatic activation function, resolving the contradiction between automation and adaptability.
2Device complexity
If airflow holes are fixed, then the device structure is simple, but suction resistance cannot be adjusted to meet different user requirements
Solution Approach 1:
The patent transforms the fixed air hole structure into a dynamic one by introducing a movable air adjusting piece that can change the effective opening area of air holes. This maintains relative structural simplicity while enabling adjustable suction resistance through the movement of the air adjusting piece within the guide groove.
3Adaptability or versatility
If the air adjusting piece is added to enable suction resistance adjustment, then user preferences can be accommodated, but the device complexity increases
Solution Approach 1:
The air adjusting piece moves within a predefined guide groove, which constrains the movement to a simple linear path. This dynamic adjustment mechanism adds minimal complexity while achieving the goal of suction resistance adjustment. The guide groove ensures the air adjusting piece moves smoothly and maintains proper sealing through the elastic piece.
Solution Approach 2:
The elastic piece acts as an intermediary between the air adjusting piece and the housing, providing sealing without requiring complex mechanical connections. This intermediary element simplifies the overall structure by using elastic deformation to achieve sealing, avoiding the need for precision-machined sealing surfaces or complex fastening mechanisms.

AI summary
An electronic cigarette with a suction resistance adjusting function includes a mouthpiece, an electronic cigarette body and an air adjusting mechanism. The air adjusting mechanism includes a microphone starting switch, a flow dividing piece, an air adjusting piece and a bottom cover. The flow dividing piece is provided with a microphone starting air hole and an air suction hole, the microphone starting switch is arranged above the microphone starting air hole. An air adjusting guide groove is provided in the bottom cover, the air adjusting piece extends out of the air adjusting guide groove and is arranged on the bottom cover. A suction resistance is adjustable by blocking air inlet areas of the microphone starting air hole and the air suction hole while stirring the air adjusting piece to move in the air adjusting guide groove.
