What it does
This humidifier uses a rotating wick mechanism and capillary action to humidify air effectively. It solves the problem of inconsistent humidification found in traditional static systems, especially in dry climates.
Your inspiration
We noticed that conventional humidifiers are either bulky, inefficient, or consume high energy. Inspired by the need for a compact and reliable solution, we designed this system to combine portability, efficiency, and adaptability.
How it works
The system features a stainless-steel rotating inner cylinder with a wick layer, driven by a 12V 100 RPM motor. Air is drawn in by a 120W centrifugal blower and passes through the moist wick. Water reaches the wick through gravity and capillary action from an overhead tank. Excess water is collected and recirculated using a diaphragm pump. Speed controllers allow fine-tuning of both airflow and rotation speed, enabling precise humidity control in different environments.
Design process
We began by studying existing humidifiers and identifying their limitations. Initial designs focused on maximizing surface area and airflow. Prototypes used Plastic containers and mesh but were later replaced with stainless steel for durability. We added a ball bearing system to reduce friction, incorporated dual pumps for water circulation, and fine-tuned airflow and rotation speed with PWM controllers. Multiple test iterations ensured optimal performance and energy efficiency.
How it is different
Unlike traditional static humidifiers, our design uses rotation to expose more wick surface area to air, improving evaporation. It's portable, adjustable, and energy-efficient. The dual-pump recirculation system ensures minimal water wastage, and the use of capillary action reduces the need for complex piping.
Future plans
We aim to miniaturize the design for household use, add sensors for auto-humidity control, and explore solar-powered operation. Commercialization as a low-cost, sustainable humidifier for arid regions is also a future goal.
