AI Technical Summary
Technical Problem
The oscillator vibration energy utilization rate of the pumping structure in a piezoelectric fan is low, resulting in low energy utilization efficiency.
Method used
An oscillator is installed in the chamber, with its free end forming a first gap and a second gap with the inlet, and forming a first space and a second space with the side wall of the chamber, respectively, thus constructing a first airflow channel and a second airflow channel. When the oscillator vibrates, it drives two streams of air to flow along the two channels respectively.
Benefits of technology
This improved the energy utilization rate of the oscillator, reduced energy loss, achieved higher airflow and velocity, and enhanced the efficiency and stability of the pump structure.
