The relative prior art of the utility model has substantive distinguishing features and progressive, specifically, this micro-vibration film air pump structural design compactness, science, volume is small, easy for installation, easy to use, it can under equal conditions produce stronger steady air flow, and the air inlet/outlet flexible design, simple in structure, the convenient application.
Description of drawings
Fig. 1 is a fractionation structural representation of the present utility model;
Fig. 2 is a sectional structure schematic representation of the present utility model.
Embodiment
Below by the drawings and specific embodiments, the technical solution of the utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of micro-vibration film air pump, comprise motor fixing frame 2, be fixed on motor 1 on the motor fixing frame 2 by jackscrew 11, flat plate 9 with inlet hole and air outlet hole has the valve 8 of two valve pores, has the air chamber 7 of vibration inlet hole and vibration air outlet hole, by the shake unit of described electric-motor-driving, and the outside is by the diaphragm 6 of described shake unit interlock;
Wherein, described air chamber 7 and flat plate 9 are fixed on the motor fixing frame 2 by screw 10;
The sealing of described diaphragm 6 inside edges is arranged at described air chamber 7 one ends, and described air chamber 7 the other ends sealing is provided with described valve 8 one ends, and described valve 8 the other ends sealing is arranged on the described flat plate 9;
Further, two described valve pore one side corresponding described vibration inlet hole one end and one end settings of described vibration air outlet hole respectively, two described valve pore opposite side corresponding described inlet hole one end and one end settings of described air outlet hole respectively, described vibration inlet hole and described vibration air outlet hole be corresponding described inlet hole and described air outlet hole setting respectively; Two described valve pores are respectively arranged with openable pneumatic airtight film, the port area of the close valve end of described air outlet hole is greater than the area of described pneumatic airtight film, the area of described pneumatic airtight film is greater than the port area of described vibration air outlet hole near valve end, the port area of the close valve end of described inlet hole is less than the area of described pneumatic airtight film, and the area of described pneumatic airtight film is less than the port area of described vibration inlet hole near valve end.
This structural design is to be subjected to gas compression or when expansion for the ease of air chamber 7, makes valve 8 finish air inlet and gives vent to anger control.
