Quick-Release Nebulizer Radial Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing nebulizers face challenges in conveniently and rapidly installing and removing the spraying head, which is essential for preventing the spread of contagious germs.
Innovation Solution
A quick-release nebulizer design that allows the spraying seat to be assembled or disassembled along the radial direction, utilizing a movable member with a handle and a T-shaped block to engage or disengage a locking mechanism, enabling rapid assembly and disassembly of the spraying head.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the spraying head is designed with a traditional fixed connection structure, then the connection is stable and reliable, but the assembly and disassembly process is time-consuming and inconvenient
Solution Approach 1:
The patent applies the dynamics principle by designing a movable member that can shift between locked and unlocked positions. The movable member includes an engaging block that can engage with or disengage from the engaging trench, enabling the spraying head to be quickly assembled or disassembled by simple linear movement rather than requiring complex fastening operations.
Solution Approach 2:
The engagement structure is segmented into distinct components: the engaging trench in the body, the engaging block on the movable member, and the T-shaped block with groove. This segmentation allows each component to perform its specific function independently, enabling rapid engagement and disengagement through simple relative movements without requiring the entire assembly to be manipulated.
2Reliability
If a locking mechanism is added to secure the spraying head, then the connection stability is improved, but the device complexity increases
Solution Approach 1:
The locking mechanism uses a movable member that can dynamically transition between locked (engaging block in engaging trench) and unlocked (engaging block disengaged from engaging trench) states. This dynamic design provides reliable locking when needed while allowing quick release when required, without requiring multiple separate locking components.
Solution Approach 2:
The patent merges the locking function with the positioning function by integrating the engaging block and engaging trench into a single engagement structure. The T-shaped block and groove combination provides both lateral positioning and axial locking in one integrated mechanism, reducing the number of separate components needed while maintaining connection stability.

AI summary
A nebulizer includes a main body (1), a spraying head (2) and an engagement structure (4). The main body (1) includes a body (11). The spraying head (2) includes a spraying seat (21) assembled to the body (11). The engagement structure (4) includes a notch (41) formed on one of the body (11) and the spraying seat (21), a T-shaped trench (42) formed on an inner wall of the notch (41), an engaging trench (43) formed on another one of the body (11) and the spraying seat (21), and a movable member (44) received in the notch (41). The movable member (44) is extended with a handle (441) exposed from the notch (41), a T-shaped block (442) slidably received in the T-shaped trench (42) and an engaging block (443) embedded in or separated from the engaging trench (43).
