Solution Overview

Problem

Current electronic cigarette atomizers experience leakage of liquid tobacco during transportation and use due to open air inlets, leading to reduced utilization and user experience.

Innovation Solution

An atomizer design featuring an atomizing assembly with airflow channels on the atomizing core and an air adjusting device, which allows controlled airflow and prevents leakage by sealing the liquid storage cavity, improving the mixing of air with smoke and allowing for adjustable airflow.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If holes are defined on the baffle piece for liquid tobacco to flow out, then liquid tobacco can be supplied to the heating coil, but liquid tobacco leaks during transportation and storage

Engineering Contradiction:
Improveliquid tobacco supplyVSAvoidleakage prevention
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent applies preliminary action by pre-defining the airflow channel structure within the atomizing core before use. The channel is formed by the circumferential outer side of the atomizing core, which preliminarily establishes a controlled pathway for air and liquid tobacco flow, preventing random leakage during transportation while ensuring proper flow during operation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent uses the atomizing core with its circumferential airflow channel as an intermediary structure. This core acts as a mediator between the liquid storage container and the heating coil, controlling the flow of liquid tobacco through its structured channels rather than allowing direct, uncontrolled flow through simple holes in the baffle piece.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If holes are totally open all the time on the baffle piece, then liquid tobacco can flow freely, but liquid tobacco cannot be prevented from leaking and being wasted

Engineering Contradiction:
Improveliquid tobacco flowVSAvoidliquid tobacco waste
Core Design Contradiction:
Ease of operationVSLoss of substance

Solution Approach 1:

The patent applies local quality by creating a specific airflow channel structure on the circumferential outer side of the atomizing core. This localized structured pathway provides controlled flow properties in specific regions, allowing liquid tobacco to flow freely where needed while preventing waste in other areas, unlike the uniform open holes in the baffle piece.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent changes the flow parameters by transitioning from simple open holes to a structured airflow channel within the atomizing core. This structural change modifies the flow characteristics, enabling controlled movement of liquid tobacco that maintains ease of flow while preventing wastage through its defined pathway geometry.

Inventive Principle:
Principle #35Parameter changes

3Use of energy by moving object

If air inlet is defined at the bottom communicating with liquid guide, then air can enter the atomizer, but liquid tobacco easily leaks from the air inlet during inhalation

Engineering Contradiction:
Improveair intakeVSAvoidleakage prevention
Core Design Contradiction:
Use of energy by moving objectVSReliability

Solution Approach 1:

The patent applies preliminary action by pre-establishing the airflow channel structure in the atomizing core before inhalation occurs. This pre-defined channel pathway controls and directs air and liquid tobacco flow, preventing leakage at the air inlet during inhalation while maintaining proper air intake functionality.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The atomizing core with its circumferential airflow channel serves as an intermediary between the air inlet and the liquid guide. This intermediary structure mediates the interaction between air flow and liquid tobacco, preventing direct leakage from the air inlet while allowing controlled mixing and atomization to occur within the structured channel.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Adaptability or versatility

If airflow channels are defined on the atomizing core, then air can enter and mix with smoke, but the structure becomes more complex

Engineering Contradiction:
Improveairflow controlVSAvoidatomizing core structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies universality by designing the atomizing core to serve multiple functions simultaneously. The circumferential outer side of the atomizing core defines airflow channels that perform both structural support and flow control functions, eliminating the need for separate, additional components and thereby reducing overall device complexity despite the enhanced airflow control capability.

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

AI summary

An atomizing head and a ventilation assembly are included in an atomizer for an electronic cigarette. The atomizing head includes an atomizing core and an atomizing tube. The circumference of the atomizing core defines airflow channels, so that air can flow into the atomizing core. This avoids the leakage caused by negative pressure when a user is inhaling smoke. The atomizer causes outside air to be more fully mixed with the smoke generated from liquid tobacco, and the user's experience is improved.
