  • Publication number: 20210017976
    Abstract: A micro pump is disclosed and includes a fluid-converging plate, a valve membrane, a fluid-outlet plate and a pump core module. The fluid-converging plate includes an inner recess, a protruding portion and a fluid-converging aperture. The protruding portion is disposed at a center of the inner recess. The valve membrane includes a valve aperture. The protruding portion of the fluid-converging plate abuts against the valve aperture. A fluid-converging chamber is formed between the valve membrane and the fluid-converging plate. The fluid-outlet plate in a ring shape includes a fluid-outlet channel. The valve aperture is in fluid communication with the fluid-outlet channel. When the fluid is inhaled into the pump core module, the fluid flows to the fluid-converging chamber through the fluid-converging aperture and then pushes out the valve membrane to flow into the fluid-outlet channel of the fluid-outlet plate through the valve aperture. Thereby the fluid transportation is achieved.

  • Patent number: 10883485
    Abstract: A driving system includes a voltage conversion module, a frequency control module, a voltage switching module and a detecting module. The voltage conversion module is used for converting a first DC voltage into a second DC voltage. The frequency control module searches a resonant working frequency of a piezoelectric actuator through circuit oscillation and generates a switching signal according to the resonant working frequency. According to the switching signal, the voltage switching module converts the second DC voltage into an AC voltage so as to drive the piezoelectric actuator. The detecting module includes a gas pressure sensor and a microcontroller. The gas pressure sensor generates a detected gas pressure value according to a result of detecting a gas pressure of the piezoelectric pump. The microcontroller controls the voltage conversion module to adjust the output voltage. Consequently, the gas pressure of the piezoelectric pump is adjusted.
