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.

A power supply integrated circuit includes a DC-DC boost regulating unit and a DC-AC output controlling unit. The DC-DC boost regulating unit is used for increasing a low DC voltage into a high DC voltage. The DC-AC output controlling unit is connected with the DC-DC boost regulating unit for converting the high DC voltage into a high AC voltage. A first portion of an integrated circuit chip and a plurality of passive components are collaboratively defined as the DC-DC boost regulating unit. A second portion of the integrated circuit chip is defined as the DC-AC output controlling unit.

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.
