Patent number: 9611843Abstract: A micro-gas pressure driving apparatus includes a miniature gas transportation module and a miniature valve module. The miniature gas transportation module includes a gas inlet plate, a fluid channel plate, a resonance membrane and a piezoelectric actuator. A first chamber is defined between the resonance membrane and the piezoelectric actuator. After the piezoelectric actuator is activated to feed a gas through the gas inlet plate, the gas is transferred to the first chamber through the fluid channel plate and the resonance membrane and then transferred downwardly. Consequently, a pressure gradient is generated to continuously push the gas. The miniature valve module includes a gas collecting plate, a valve membrane and a gas outlet plate. After the gas is transferred from the miniature gas transportation module to the gas-collecting chamber, the gas is transferred in one direction, so that a pressure-collecting operation or a pressure-releasing operation is selectively performed.Type: GrantFiled: May 7, 2014Date of Patent: April 4, 2017Assignee: MICROJET TECHNOLOGY CO., LTD.Inventors: Ta-Wei Hsueh, Ying-Lun Chang, Hsiang-Dyi Wu, Rong-Ho Yu, Shih-Chang Chen, Tsung-Pat Chou, Yau-Ji Lee, Jia-Yu Liao

Patent number: 8864046Abstract: A closed nebulizing system for removing bubbles includes a first pump, a nebulizing module and a second pump. The first pump is for providing a fluid. The nebulizing module includes an outlet channel, an inlet channel connected with the first pump, and a plurality of nozzles for nebulizing and ejecting part of the fluid. The second pump is connected with the outlet channel for outputting non-nebulized fluid. The first pump, the nebulizing module and the second pump form a closed fluid loop, so that the fluid continuously contacts with the plurality of nozzles and bubbles generated during nebulization process are evacuated from the nebulizing module.Type: GrantFiled: October 14, 2011Date of Patent: October 21, 2014Assignee: Microjet Technology Co., Ltd.Inventors: Shih-Chang Chen, Shih-Che Chiu, Tsung-Pat Chou

Patent number: 8579606Abstract: A fluid transportation device includes a valve seat, a valve cap, a valve membrane, and an actuating module. The valve seat has an outlet channel and an inlet channel. The valve cap has a tilt structure. The valve membrane has an inlet valve structure and an outlet valve structure. The actuating module has a vibration film and an actuator. When the fluid transportation device is in a non-actuation status, a pressure cavity with a gradually-increasing depth is defined. When a voltage is applied on the actuator to result in deformation of the actuator, the vibration film generates a pressure difference to push the fluid. The fluid is introduced into the inlet valve structure through the inlet channel, guided by the tilt structure of the valve cap to be flowed from the pressure cavity to the outlet valve structure, and then flowed out of the outlet channel.Type: GrantFiled: October 12, 2011Date of Patent: November 12, 2013Assignee: Microjet Technology Co., Ltd.Inventors: Shih-Chang Chen, Shih-Che Chiu, Tsung-Pat Chou
