Atomizer Control Switch With Dual Buttons and Flow Regulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing atomizers suffer from mistouch activation due to a fixed button configuration, leading to inconvenient operation and inability to regulate outlet flow rate, and share a common button for fan and water outlet control.
Innovation Solution
A control switch and regulating mechanism with separate push and press buttons, utilizing a rotating rod and torsion spring system to prevent mistouch and allow independent control of the fan and water outlet, along with a spline shaft and gear system for flow rate adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single button is used to control both fan and water outlet, then device complexity is reduced, but ease of operation deteriorates due to mistouch activation and inability to independently control functions
Solution Approach 1:
The single button control is segmented into two distinct buttons: a push button for fan control and a press button for water outlet control. This segmentation allows independent control of each function, preventing mistouch activation while maintaining manageable device complexity through clear functional separation.
Solution Approach 2:
The press button is designed with rotational capability around a rotating rod, transforming it from a static push component to a dynamic control mechanism. This dynamic design enables the press button to be pressed downward to activate the water outlet while returning to its original position, providing intuitive operational feedback and preventing accidental activation.
2Device complexity
If a fixed-length connecting rod is used, then device complexity is reduced, but adaptability deteriorates due to inability to regulate outlet flow rate
Solution Approach 1:
The fixed-length connecting rod is replaced with an adjustable-length mechanism comprising a rotating ferrule that can move along a spline shaft. The rotating ferrule's position can be adjusted by rotating an adjusting knob, which drives the ferrule along the spline shaft's threads. This dynamic adjustment capability allows the connecting rod length to be varied, enabling flow rate regulation while maintaining relatively simple device structure.
Solution Approach 2:
The connecting rod length parameter is made variable through the spline shaft and rotating ferrule mechanism. By changing the position of the rotating ferrule along the spline shaft, the effective length of the connecting rod is adjusted, thereby regulating the outlet flow rate. This parameter change approach provides adaptability without significantly increasing device complexity.
3Ease of operation
If the button is located below the handle for easy access, then ease of operation is improved, but reliability deteriorates due to mistouch activation when users take the atomizer
Solution Approach 1:
The control functions are segmented into two separate buttons with distinct operating mechanisms: a push button requiring lateral pressing motion for fan control, and a press button requiring downward pressing motion for water outlet control. This segmentation ensures that neither button can be accidentally activated during normal handling, as the required pressing directions are orthogonal to typical picking motions.
Solution Approach 2:
The press button incorporates a rotating rod mechanism that allows the button to rotate around its axis when pressed downward. This dynamic rotational feature provides tactile feedback to confirm activation and ensures that only deliberate downward pressing activates the function, preventing mistouch during lateral picking motions.

Implementation Method 1
the rotating rod is sleeved with a torsion spring for driving an end, away from the regulating mechanism, of the press button to rotate downwards around the rotating rod
Implementation Method 2
a fixed pillar is fixedly arranged on an end face, facing the press button, of the fixed rod, the fixed pillar is sleeved with a spring for driving the push button to move away from the press button

AI summary
A control switch and regulating mechanism for an atomizer is provided. A push button is pushed to move towards a press button to start a fan by a fan controller, the push button drives a fixed rod on the push button to be located above a clamping groove in the press button, the press button is held to drive an end of the press button to rotate upwards around a rotating rod until the clamping groove in the press button clamps a lower end of the fixed rod, and an atomizer starts to spray water; either the push button or the press button is pressed separately, the atomizer will not spray water; and a spring can apply a force to the fixed rod to drive the fixed rod to move away from the press button until the lower end of the fixed rod is steadily clamped in the clamping groove.
