20120318260 | PORTABLE NEBULIZING APPARATUS - A nebulizing apparatus includes a housing, a carrying cavity, an nebulizing element, a slide element and a circuit board. The carrying cavity is formed in the housing for carrying a nebulized liquid and the carrying cavity includes a through hole. The nebulizing element is installed at the through hole. The slide element is slidably installed on a side of the housing and includes a magnet. The circuit board is installed on an internal side of the housing and includes a magnetic switch installed on a side of the circuit board. When the slide element is move to an ON position, the magnetic switch is turned on by the magnetism of the magnet, so that the nebulizing element can spray the nebulized liquid. | 12-20-2012 |
20120205468 | NOZZLE PLATE AND ATOMIZING MODULE USING THE SAME - A nozzle plate and an atomizing module using the nozzle plate are disclosed. The atomizing module is installed at a cavity and includes a piezoelectric circular plate, a braking circular plate and a nozzle plate. The braking circular plate is installed on a side of the piezoelectric circular plate. The nozzle plate is a circular disc clamped between the piezoelectric circular plate and the braking circular plate, and the nozzle plate includes firing holes and first protrusions. Each first protrusion is non-circular and protruded in a direction towards the piezoelectric circular plate or the braking circular plate to form a multi-curved surface structure radially or circularly arranged into a specific geometric pattern. The nozzle plate can increase the atomizing area, atomizing quantity and liquid-gas exchange rate to prevent excessive stresses from concentrating at the center of the nozzle plate or vibrations from cracking or breaking the nozzle plate. | 08-16-2012 |
20100068080 | WIRING STRUCTURE FOR USE IN MICRO PIEZOELECTRIC PUMP - An electrical connection structure for use in a micro piezoelectric pump is disclosed. The electrical connection structure includes a driving circuit board and a multilayered wiring structure. The electrical connection structure includes the driving circuit board, the wiring structure, and a piezoelectric element arranged from top to bottom.
