Referring to fig. 1, 2 and 4, in the present embodiment, after the air inlet plate 16, the resonator plate 17 and the outer frame 12 are assembled in sequence, the resonator plate 17 has a movable portion 17a and a fixed portion 17b, the movable portion 17a and the air inlet plate 16 thereon form a chamber for collecting gas, and a first chamber 10 is further formed between the resonator plate 17 and the suspension plate 11, the bracket 13 and the outer frame 12 for temporarily storing gas, the first chamber 10 is communicated with the collecting chamber at the central recess 16c of the air inlet plate 16 through the hollow hole 17c of the resonator plate 17, and two sides of the first chamber 10 are communicated with the fluid channel through the gap 15 of the bracket 13.
Referring to fig. 1, 2, 4, and 5A to 5E, when the piezoelectric sheet 14 is actuated by voltage, the support 13 is used as a fulcrum to perform reciprocating vibration in the vertical direction. As shown in fig. 5A, when the piezoelectric sheet 14 is actuated by voltage to vibrate downwards, since the resonance sheet 17 is a light and thin sheet-like structure, when the piezoelectric sheet 14 vibrates, the resonance sheet 17 also vibrates vertically and reciprocally along with the resonance, that is, the portion of the resonator plate 17 corresponding to the central recess 16c is deformed by bending vibration, that is, the portion corresponding to the central recess 16c is the movable portion 17a of the resonator plate 17, so that when the piezoelectric plate 14 bends and vibrates downward, at this time, the movable portion 17a of the resonator plate 17 corresponding to the central recess 16c is brought by the gas and pushed and the piezoelectric sheet 14 is vibrated, and, as the piezoelectric sheet 14 is deformed by bending vibration downward, gas enters through at least one gas inlet hole 16a of the gas inlet plate 16, and then flows into the first chamber 10 through at least one bus bar hole 16b to be collected at the central concave portion 16c and then through the hollow hole 17c of the resonance sheet 17 corresponding to the central concave portion 16 c. Thereafter, the resonator plate 17 is driven by the vibration of the piezoelectric plate 14 to perform vertical reciprocating vibration along with the resonance, as shown in fig. 5B, at this time, the movable portion 17a of the resonator plate 17 also vibrates downward along with the vibration and is attached to and abutted against the convex portion 11a of the suspension plate 11, so that the distance between the confluence chamber between the region outside the convex portion 11a of the suspension plate 11 and the fixing portions 17B at both sides of the resonator plate 17 is not decreased, and the volume of the first chamber 10 is compressed by the deformation of the resonator plate 17, and the middle circulation space of the first chamber 10 is closed, so that the gas in the first chamber is pushed to flow to both sides, and further flows downward through the gap 15 between the brackets 13 of the piezoelectric plate 14. Then, as shown in fig. 5C, the movable portion 17a of the resonator plate 17 is bent and vibrated to return to the initial position, and the piezoelectric plate 14 is driven by the voltage to vibrate upwards, so as to press the volume of the first chamber 10, but at this time, since the suspension plate 11 is lifted upwards, the gas in the first chamber 10 flows towards both sides, and the gas continuously enters from the at least one gas inlet hole 16a of the gas inlet plate 16 and then flows into the confluence chamber formed by the central recess 16C. Then, as shown in fig. 5D, the resonator plate 17 resonates upward due to the upward vibration of the suspension plate 11, and the movable portion 17a of the resonator plate 17 also vibrates upward, so as to slow down the gas from continuously entering from the at least one gas inlet hole 16a of the gas inlet plate 16, and then flowing into the converging chamber formed by the central concave portion 16 c. Finally, as shown in fig. 5E, the movable portion 17a of the resonator plate 17 is also returned to the initial position, so that the maximum distance of the vertical displacement of the resonator plate 17 can be increased by the gap h between the resonator plate and the outer frame 12 when the resonator plate 17 performs vertical reciprocating vibration, in other words, the gap h is provided between the two structures to allow the resonator plate 17 to generate a larger vertical displacement at the time of resonance. Therefore, a pressure gradient is generated in the flow channel design of the fluid actuator 13, so that the gas flows at a high speed, and the gas is transmitted from the suction end to the discharge end through the impedance difference in the inlet and outlet directions of the flow channel to complete the gas transmission operation, even if the discharge end has air pressure, the gas can still be continuously pushed into the fluid channel, and the silencing effect can be achieved, so that the actions of the figures 5A to 5E are repeated, and the gas transmission from the outside to the inside can be generated.
In summary, the actuator provided by the present disclosure generates a pressure gradient in the designed flow channel by the fluid fluctuation generated by the high-frequency actuation of the piezoelectric plate, so that the fluid flows at a high speed, and the fluid is transmitted from the suction end to the discharge end through the impedance difference in the inlet and outlet directions of the flow channel, so that the fluid flows at a high speed and can be continuously transmitted, thereby achieving the effects of rapidly transmitting the fluid and muting the fluid, further reducing the overall volume and thinning the actuator, and achieving the portable purpose of being light and comfortable. In addition, this scheme passes through the surface of air inlet plate, piezoelectric plate electrode coating doping graphite alkene material synthetic coating, and then reaches the excellent radiating effect. Therefore, the present application has great industrial application value, and the application is provided by the method.
Various modifications may be made by those skilled in the art without departing from the scope of the invention as defined by the appended claims.
