Solution Overview
Problem
Conventional airflow heating devices for tobacco, fragrance, or herbs suffer from inadequate heating speed and non-uniform heating, leading to unnecessary waste of raw materials due to continuous heating without suction.
Innovation Solution
An airflow heating assembly comprising a heating device with an outer ceramic pipe and inner ceramic rod, a high-temperature resistant spiral guiding groove, and a detachable container with an airflow homogenizing device, which ensures rapid and uniform heating of airflow by using thermistor and heating wires integrated with the ceramic components and intelligent temperature control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single heating pipe is used to heat airflow, then the device structure is simple, but the heating speed is slow and heating uniformity is poor
Solution Approach 1:
The heating device is segmented into an outer heating pipe and an inner heating rod, creating a multi-zone heating system. The outer heating pipe heats the airflow from the outside, while the inner heating rod provides additional heating from the inside, working together to rapidly heat the airflow uniformly without requiring complex external control systems.
Solution Approach 2:
The inner heating rod is nested within the outer heating pipe, forming a compact concentric heating structure. This nested arrangement allows both heating elements to occupy minimal space while maximizing their heating efficiency, enabling rapid and uniform airflow heating without significantly increasing device complexity.
2Reliability
If continuous heating is applied without suction detection, then the heating function is always available, but raw material is wasted unnecessarily
Solution Approach 1:
A suction detection mechanism provides feedback to the heating system, detecting when user suction occurs. The heating element receives this feedback signal and activates heating only when suction is detected, ensuring the heating function is reliably available when needed while preventing raw material waste during non-use periods.
3Ease of manufacture
If heating wire and thermistor are separately assembled, then the ceramic pipe structure is simple, but the temperature control precision is insufficient
Solution Approach 1:
The heating wire and thermistor are merged into an integrated assembly that is pre-assembled together before being inserted into the ceramic pipe. This merging ensures precise spatial positioning and electrical connection between the heating element and temperature sensor, achieving accurate temperature control while maintaining simple ceramic pipe structure through modular design.
