Solution Overview

Problem

Existing electronic cigarettes require the removal of a suction nozzle for refilling, which is inconvenient and can lead to the nozzle becoming dirty or lost.

Innovation Solution

An atomizer device with a rotatable adjusting valve that allows for liquid solution injection without removing the suction nozzle, featuring a sliding adjusting cover and sealing unit to open and close a liquid injection channel, and an air inlet assembly for adjustable airflow.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the suction nozzle is removed for injecting liquid solution into the cartridge, then the liquid solution can be injected into the cartridge, but the suction nozzle may easily drop off to get dirty or get lost

Engineering Contradiction:
Improveliquid solution injectionVSAvoidsuction nozzle handling
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

The patent merges the suction nozzle with the cartridge assembly by providing a threading structure that allows the suction nozzle to be screwed onto the cartridge. This integration ensures the suction nozzle remains attached during liquid solution injection, eliminating the problem of the nozzle dropping off, getting dirty, or getting lost while still allowing access to the cartridge for refilling.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of manufacture

If the suction nozzle is removed for injecting liquid solution, then the liquid solution can be injected, but the operation becomes troublesome

Engineering Contradiction:
Improveliquid solution injectionVSAvoidrefilling operation time
Core Design Contradiction:
Ease of manufactureVSLoss of time

Solution Approach 1:

The patent incorporates a pre-designed liquid solution injection channel within the cartridge structure, with a dedicated injection opening. This preliminary design allows users to inject liquid solution directly into the cartridge through the opening without needing to remove the suction nozzle, significantly reducing the time and complexity of the refilling operation.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If a rotatable adjusting valve is added to control the liquid injection channel, then the liquid injection can be controlled, but the device complexity increases

Engineering Contradiction:
Improveliquid injection controlVSAvoidadjusting valve mechanism
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent employs a rotatable adjusting valve that can be rotated between different positions to dynamically control the opening and closing of the liquid injection channel. This dynamic mechanism provides simple yet effective control over liquid injection, allowing users to open the channel for refilling and close it for normal operation, without requiring a complex multi-component valve system.

Inventive Principle:
Principle #15Dynamics

AI summary

An electronic cigarette and an atomizer device thereof are provided. The atomizer device includes a housing, a liquid reservoir chamber (115) formed in the housing, and a adjusting valve (13) engaging with the housing; a liquid injection channel (1131) is defined in the housing for injecting liquid solution into the liquid reservoir chamber (115); a first opening (1311) corresponding to the liquid injection channel (1131) is defined in the adjusting valve (13); the adjusting valve (13) is movable between a first position and a second positon across a surface of the housing; when the adjusting valve is in the first position, the first opening (1311) communicates with the liquid injection channel (1131) to open the liquid injection channel (1131), and when the adjusting valve (13) is in the second positon, the first opening (1311) misaligns with the liquid injection channel (1131) to close the liquid injection channel (1131). In the solution of the present disclosure, the adjusting valve (13) is movable between the first position and the second position such that the first opening (1311) of the adjusting valve (13) can be adjusted to open or close the liquid injection channel (1131), thus, the injection of the liquid solution is facilitated; in addition, since the liquid solution can be injected into the atomizer device without removing the suction nozzle, the injection of the liquid solution is convenient and simplified and the situation that the suction nozzle gets dirty or get lost can be avoided.
