Rotatable Cover Mechanism for Portable Atomizer Discharge Hole
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable atomizers with pressurizing-type discharge mechanisms often face issues with the exposure of discharge holes, leading to contamination and inconvenience in managing additional caps, which can result in inefficient and uncontrolled dispensing of substances like cosmetics.
Innovation Solution
A spray structure for portable atomizers featuring a rotatable and linearly movable cover with an elastic portion, a connection cap, and a protrusion-groove assembly, which allows for controlled exposure of the discharge hole and prevents contamination by ensuring the discharge hole is only exposed when intended, enabling easy one-handed operation and direction control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the discharge hole is exposed to the outside, then the substance can be discharged, but the discharge hole is susceptible to contamination
Solution Approach 1:
The cover is designed to be rotatable about a first axis, transitioning between a closed position (covering the discharge hole) and an open position (exposing the discharge hole). This dynamic mechanism allows the discharge hole to be exposed only when needed for substance discharge, while remaining covered otherwise to prevent contamination.
2Object-affected harmful factors
If an additional protective cap is provided, then the discharge hole is protected from contamination, but the device complexity increases
Solution Approach 1:
The protective function is merged with the existing cover structure. The cover serves dual purposes: it acts as a protective cap when closed and as an operational component when opened for discharge. This eliminates the need for a separate protective cap, reducing device complexity while maintaining contamination protection.
Solution Approach 2:
The cover is designed to perform multiple functions: protecting the discharge hole from contamination when closed, and enabling substance discharge when opened. This multi-functional design replaces the need for separate protective caps, simplifying the overall device structure.
3Ease of operation
If the cover is made rotatable and linearly movable, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The cover is designed with rotational freedom about a first axis, allowing easy transition between closed and open positions. This dynamic design enables intuitive one-handed operation and direction control, with the elastic portion providing automatic return force to the closed position.
Solution Approach 2:
The elastic portion automatically returns the cover to the closed position after opening, eliminating the need for manual resetting. This self-service mechanism simplifies operation while maintaining the rotational and linear movement capabilities.
4Reliability
If the elastic portion is added, then the reliability of the cover return mechanism is improved, but the device complexity increases
Solution Approach 1:
The elastic portion automatically returns the cover to the closed position after it has been opened for discharge. This self-service mechanism ensures reliable resetting without requiring manual intervention, improving reliability while adding only a simple elastic component.
Solution Approach 2:
The elastic portion provides a quick return mechanism that rapidly returns the cover to the closed position after opening, ensuring the discharge hole is promptly protected. This rushing through the return action enhances reliability while maintaining simplicity.

Function Achieved in This Case
The solution provides a user-friendly and efficient mechanism for dispensing substances by ensuring the discharge hole is only exposed when needed, preventing contamination and allowing for precise direction control without visual confirmation, enhancing the usability and reliability of portable atomizers.
Implementation Method 1
an elastic portion between the head portion and the cover, wherein the cover is configured to be rotatable about on a first axis by a first angle above the head portion
Implementation Method 2
when the cover is rotated by the first angle, a second end portion of the elastic portion may provide force to the cover through an opening of the connection cap

AI summary
A spray structure for a portable atomizer includes: a case including an opening; a cover exposed through the opening of the case; a head portion placed in the case and coupled to the cover, the head portion including a discharge hole; and an elastic portion between the head portion and the cover, wherein the cover is configured to be rotated on a first axis by a first angle above the head portion to expose the discharge hole through the opening of the case and to be linearly moved in a second direction perpendicular to the first axis in a state in which the discharge hole is exposed.
