Diffuser With Rotatable Cover For Airflow Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aroma diffusers often require separate components for scent dispersion, leading to noise interference that can disrupt mental and physical stability, and they typically need additional electronic control for volatilization adjustment.
Innovation Solution
A diffuser design that utilizes an integrated fan to generate an air current for scent dispersion, eliminating the need for separate scent spraying components and reducing noise, while also incorporating a rotatable cover mechanism for controlling airflow without electronic control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If separate components for scent spraying are used, then scent dispersion function is improved, but noise is generated that interferes with user stability
Solution Approach 1:
The patent combines the scent storage function and the air blowing function into a single integrated base unit. The aroma container is coupled to the base, and the fan is coupled to cover a portion of the through-portion, creating a unified structure that eliminates the need for separate spraying components and reduces noise generation.
Solution Approach 2:
The base is designed to perform multiple functions: it stores aroma (aroma container coupled to base), generates airflow (fan coupled to base), and controls the communication between internal spaces through the rotatable cover. This multi-functional design eliminates separate components and reduces overall system noise.
2Ease of operation
If separate driving units are provided for controlling scent volatilization, then scent control function is improved, but device complexity and noise increase
Solution Approach 1:
The rotatable cover mechanism allows the system to control the communication between the body's internal space and the base's internal space through simple mechanical rotation. When the cover rotates to expose the through-portion, air flow is enabled; when it blocks the through-portion, air flow is stopped. This self-service mechanism eliminates the need for separate electronic control units.
Solution Approach 2:
The cover is designed to be rotatable, allowing dynamic control of the airflow path. The cover can rotate to different positions to selectively open or block the through-portion, providing flexible scent control without requiring complex electronic driving units.
3Ease of operation
If a rotatable cover mechanism is used, then airflow control is improved, but device complexity increases
Solution Approach 1:
The rotatable cover serves multiple functions: it seals the through-portion when in the closed position, allows airflow control when rotated, and provides a user interface for operation. This multi-functional design justifies the mechanical complexity by eliminating the need for separate electronic control systems.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The diffuser effectively disperses scent solely through an air current generated by the fan, reducing noise and enhancing user comfort, while allowing for easy maintenance and operation without separate electronic controls.
Implementation Method 1
a fan coupled to cover a first portion of the through-portion to form flow of air
Implementation Method 2
an internal space of the body and an internal space of the base are selectively communicated with each other as the cover is rotated

AI summary
Provided is a diffuser equipped with an integrated cover that is opened and closed by an air current formed when a fan module is driven to control the spread of scent. The diffuser includes a body forming an exterior, a base inserted and fixed into the body and having a through-portion formed on one surface thereof, and an aroma container coupled to the base, wherein the base includes a cover rotatably provided on the through-portion, and an internal space of the body and an internal space of the base are selectively communicated with each other as the cover is rotated.
