Nebulizer Solution
1. Product Overview
The atomizer is a device based on a circuit board where an oscillating signal is amplified by a high-power transistor and transmitted to a piezoelectric ceramic chip. When the piezoelectric ceramic chip is excited by the electrical signal, it generates high-frequency resonance, causing the liquid droplets adsorbed on the microporous membrane to produce ultrasonic oscillations, disrupting the structure of the liquid and generating naturally floating mist. No heating or addition of any chemical reagents is required, and compared to heating atomization methods, it saves 90% of energy.
2. Product characteristics
Noise level of the entire machine during normal operation: <50db
The atomization rate of the atomizer is ≥0.25mL/min, and the proportion of mist particles smaller than Φ5μm is >55%
It can be powered by 2 dry batteries or an external USB supply with DC5V
Standby current < 10uA uA
Using an 8-bit high-speed low-power MCU facilitates the development of extended functions
II. Key components
Main control chip: Selected according to requirements
III. Detailed Explanation of Measurement Principle
1. Press the button to turn on the device and check the atomization rate. The blue light will be on continuously
2.2.2V±0.2 low voltage protection, orange light flashes 5 times, atomizer stops working
3. Turn off the device to check the standby current
4. When there is no water, the atomizer stops working
5. Using 2 AA dry batteries, the atomizer should be able to operate continuously for 1 hour after being turned on (it is allowed to add an appropriate amount of drinking water or tap water to the atomizer's liquid tank during operation, but pure water cannot be used), and the atomizer should function normally
