Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing atomizers for electronic cigarettes have complex structures due to separate liquid inlet and gas adjusting devices, leading to potential smoke liquid leakage during liquid injection due to pressure differences, affecting user experience.
Innovation Solution
An atomizer with a switching device comprising a movable and static piece that can switch between liquid injection and gas inflow adjustment states, ensuring gas inlets are closed during liquid injection to prevent leakage, featuring ceramic construction for smooth contact and a pin connection for rotation-driven operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If liquid inlet and gas adjusting device are provided separately, then the atomizer can perform both liquid injection and gas inflow adjustment functions, but the atomizer structure becomes complicated
Solution Approach 1:
The patent combines the liquid inlet device and gas adjusting device into a single integrated switching device. The switching device includes a movable piece and a static piece that work together to control both liquid injection and gas inflow adjustment functions through a unified structure, eliminating the need for separate devices and reducing overall structural complexity.
Solution Approach 2:
The switching device is designed as a multi-functional component that can perform both liquid injection and gas inflow adjustment operations. By incorporating both liquid inlet and gas inlet channels within the same device, it serves multiple purposes simultaneously, improving adaptability while reducing the number of separate components needed.
2Productivity
If smoke liquid is directly injected into the atomizer, then liquid injection is simple and fast, but smoke liquid leakage occurs due to pressure difference when gas inflow channel is open
Solution Approach 1:
The switching device is designed to automatically close the gas inlet channel before liquid injection begins. The movable piece and static piece are positioned such that when liquid injection is activated, the gas inlet is already sealed, preventing pressure difference-induced leakage. This preliminary closing action eliminates the harmful effect before it can occur.
Solution Approach 2:
The switching device acts as an intermediary mechanism between the liquid injection system and gas inflow system. It coordinates the timing and state of both channels, ensuring that gas inlet is closed when liquid injection occurs, thereby mediating the interaction between these two functions to prevent leakage while maintaining both capabilities.
3Adaptability or versatility
If gas adjusting device is provided, then gas inflow can be adjusted, but user may forget to close it during liquid injection, causing leakage
Solution Approach 1:
The switching device is designed to automatically manage both liquid injection and gas inflow adjustment without requiring separate user operations. When liquid injection is activated, the device self-regulates by closing the gas inlet channel through the movable piece and static piece mechanism, eliminating the need for users to manually close the gas adjusting device and preventing leakage through automated control.

AI summary
Provided are an atomizer (100) and an electronic cigarette thereof, the atomizer comprising a switching device (1), a liquid storage component (3) and an atomization component. The atomization component is disposed in the liquid storage component (3), and the switching device (1) includes a movable piece (13) and a static piece (14) that are cooperatively arranged, and the movable piece (13) is capable of moving relative to the static piece (14) to make the atomizer (100) switch between two states of liquid injection and gas inflow adjustment. The movable piece (13) and the static piece (14) are each provided with a liquid inlet and a gas inlet. When the atomizer (100) is in the state of liquid injection, the gas inlets are closed to avoid a possible leakage of smoke liquid from the atomization head (5) during liquid injection due to a pressure difference when the gas inlets communicate.
