Solution Overview

Problem

Conventional electronic cigarette atomizing devices with liquid reserving members suffer from chemical reactions that affect the taste of the tobacco solution over time, and they have limited space for storing tobacco liquid, reducing the smoking experience.

Innovation Solution

A ventilation member with a T-shaped design and an inclined surface is integrated into the atomizing device, eliminating the need for a liquid reserving member by using a cavity within the flange and air pipe to reserve and purify the atomized tobacco solution, while a guiding wall and sealing ring ensure secure assembly and prevent leakage, thereby increasing the space for tobacco liquid storage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If a liquid reserving member is used to store tobacco solution, then the storage function is provided, but the liquid reserving member causes chemical reaction and influences the taste of the tobacco solution after long time immersion

Engineering Contradiction:
Improvetobacco solution storageVSAvoidchemical reaction affecting taste
Core Design Contradiction:
Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The patent removes the liquid reserving member from the atomizing device structure. Instead of having a separate container for tobacco solution, the design integrates the storage function into the air pipe cavity, eliminating the material that causes chemical reactions and taste degradation over time.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent combines the air pipe and liquid storage cavity into a single integrated structure. The air pipe itself serves dual functions as both the airflow channel and the tobacco solution storage cavity, reducing the number of components and eliminating the liquid reserving member that causes chemical reactions.

Inventive Principle:
Principle #5Merging (Combining)

2Quantity of substance

If a liquid reserving member is used to store tobacco solution, then the storage function is provided, but the space for storing tobacco liquid is limited

Engineering Contradiction:
Improvetobacco solution storage capacityVSAvoidstructure complexity
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The patent merges the air pipe and liquid storage cavity into one integrated component. This combination increases the tobacco solution storage capacity without adding separate parts, as the cavity within the air pipe structure is utilized for liquid storage.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The air pipe is designed to serve multiple functions: it acts as both the airflow channel and the tobacco solution storage cavity. This multi-functionality increases storage capacity while avoiding the need for additional dedicated storage components.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Reliability

If the ventilation member is integrated into the atomizing device, then the assembly is secured and leakage is prevented, but the device complexity increases

Engineering Contradiction:
Improveleakage preventionVSAvoidassembly complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The ventilation member is integrated directly into the air pipe structure, forming a unified component. This integration secures the assembly and prevents leakage at interfaces, while the merging of functions reduces the number of separate parts that would otherwise increase complexity.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

An atomizing device of an electronic cigarette without a liquid reserving member is provided. The atomizing device includes an atomizing sleeve, a support, a heating assembly, and a ventilation member fixed inside the atomizing sleeve. The ventilation member includes an air pipe and a flange formed on the air pipe. The flange includes a cavity in communication with the air pipe, and the air pipe is fixed on the support. An annular space for containing a tobacco solution is formed between the air pipe and the atomizing sleeve. The heating assembly is placed under the support. An electronic cigarette having the atomizing device and the ventilation member is also disclosed.
