Air supply device with air refreshing and mosquito repelling function
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electric fans and heaters serve only single functions, requiring separate purchases for cooling and heating, and additional devices for aromatherapy and mosquito repellent, which is costly and space-consuming, and inconvenient to use.
Innovation Solution
An integrated air supply device that combines the functions of a fan, heater, aromatherapy diffuser, and mosquito repellent diffuser, featuring a centrifugal fan, heating component, and interchangeable aromatherapy or mosquito repellent components, with a compact design and easy operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate devices (fan, heater, aromatherapy diffuser, mosquito repellent device) are purchased to provide different functions, then the functional versatility is improved, but the device complexity and space occupation increase
Solution Approach 1:
The patent combines a fan unit, heater unit, aromatherapy diffuser unit, and mosquito repellent device into a single integrated air supply device. The housing contains all four functional units that can operate independently or in combination, allowing users to replace multiple separate devices with one unified system that provides cooling, heating, aromatherapy, and mosquito repellent functions simultaneously.
Solution Approach 2:
The air supply device is designed as a universal device that can perform multiple functions: air circulation (fan), heating (heater), aromatherapy diffusion, and mosquito repellent. The device incorporates interchangeable cartridges that allow it to adapt to different functional needs, making it a multi-functional replacement for several specialized devices.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Provides a cost-effective, space-efficient solution for air refreshing and mosquito repellent functions, optimizing indoor air conditions and environment, while allowing for easy switching between fan and heater modes, with efficient airflow and convenient assembly.
Implementation Method 1
a PTC heating plate sandwiched between the upper electrode plate and the lower electrode plate and electrically connected to the upper electrode plate and the lower electrode plate
Implementation Method 2
the aroma sheet or the mosquito repellent sheet are interchangeable for use, wherein the heating body is positioned at the auxiliary air inlet
Implementation Method 3
a centrifugal fan received inside the air duct unit
Implementation Method 4
a heating component detachably connected to the housing at one of the main air inlet serving as an optional component for heating air intake from one of the main air inlets
