In other embodiments, the height of the outer frame 1332 of the high voltage actuator 133 may be increased to increase a gap when the resonant plate 132 is assembled with the high voltage actuator, but not limited thereto.

Referring to fig. 2C, 2D, 3A, 3B and 5, in the present embodiment, after the air inlet plate 131, the resonator plate 132 and the piezoelectric actuator 133 are correspondingly assembled in sequence, the resonator plate 132 has a movable portion 132a and a fixed portion 132B, the movable portion 132a and the air inlet plate 131 thereon form a chamber for collecting air, and a first chamber 130 is further formed between the resonator plate 132 and the piezoelectric actuator 133 for temporarily storing air, the first chamber 130 is communicated with the chamber at the central recess 131C of the air inlet plate 131 through the hollow hole 132C of the resonator plate 132, and two sides of the first chamber 130 are communicated with the channel 17 through the gap 1335 between the brackets 1333 of the piezoelectric actuator 133.

Referring to fig. 2C, 2D, 3A, 3B, 5, and 6A to 6E, the operation of the fluid actuator 13 of the present invention is briefly described as follows. When the fluid actuator 13 is operated, the piezoelectric actuator 133 is driven by a voltage to perform reciprocating vibration in the vertical direction with the support 1333 as a fulcrum. As shown in fig. 6A, when the piezoelectric actuator 133 is actuated by a voltage to vibrate downward, because the resonance plate 132 is a light and thin sheet-like structure, when the piezoelectric actuator 133 vibrates, the resonance plate 132 also vibrates vertically in a reciprocating manner along with the resonance, i.e. the portion of the resonance plate 132 corresponding to the central recess 131c also deforms along with the bending vibration, i.e. the portion corresponding to the central recess 131c is the movable portion 132a of the resonance plate 132, when the piezoelectric actuator 133 vibrates in a downward bending manner, the movable portion 132a of the resonance plate 132 corresponding to the central recess 131c is pushed and pressed by air and driven by the piezoelectric actuator 133 to vibrate, and along with the bending vibration of the piezoelectric actuator 133, the air enters from at least one air inlet hole 131a on the air inlet plate 131 and is collected to the central recess 131c through at least one row of bus holes 131b, and then flows downward into the first chamber 130 through a hollow hole 132c of the resonance plate 132, which is provided corresponding to the central recess 131 c. Thereafter, as the piezoelectric actuator 133 is driven to vibrate, the resonator 132 also vibrates vertically and reciprocally along with the resonance, as shown in fig. 6B, at this time, the movable portion 132a of the resonator 132 also vibrates downward along with the resonance and sticks and abuts on the protrusion 1331a of the floating plate 1331 of the piezoelectric actuator 133, so that the distance between the confluence chambers between the region other than the protrusion 1331a of the floating plate 1331 and the fixing portions 132B at both sides of the resonator 132 is not decreased, and the deformation of the resonator 132 compresses the volume of the first chamber 130, closes the middle flow space of the first chamber 130, and causes the air therein to flow to both sides, and further to flow downward through the gap 1335 between the brackets 1333 of the piezoelectric actuator 133. Then, as shown in fig. 6C, the movable portion 132a of the resonator plate 132 is bent and vibrated to return to the initial position, and the piezoelectric actuator 133 is driven by the voltage to vibrate upwards, so as to press the volume of the first chamber 130, but at this time, since the piezoelectric actuator 133 is lifted upwards, the air in the first chamber 130 flows towards both sides, and the air continuously enters from the at least one air inlet hole 131a of the air inlet plate 131 and then flows into the chamber formed by the central recess 131C. Then, as shown in fig. 6D, the resonance plate 132 resonates upward due to the upward vibration of the piezoelectric actuator 133, and the movable portion 132a of the resonance plate 132 vibrates upward, so as to slow down the air from continuously entering the at least one air inlet hole 131a of the air inlet plate 131, and then flows into the chamber formed by the central recess 131 c. Finally, as shown in fig. 6E, the movable portion 132a of the resonator plate 132 returns to the initial position, so that when the resonator plate 132 performs vertical reciprocating vibration, the maximum distance of the vertical displacement can be increased by the gap h between the resonator plate and the piezoelectric actuator 133, in other words, the gap h between the two structures can enable the resonator plate 132 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 to make the air flow at a high speed, and the air 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 air conveying operation, even if the discharge end has air pressure, the air can be continuously pushed into the channel 17, and the silencing effect can be achieved, so that the fluid actuator 13 can generate the air transmission from the outside to the inside by repeating the operation of the fluid actuator 13 in fig. 6A to 6E.

In view of the above, the operation of the fluid actuator 13 is further described below, the air inlet plate 131, the resonance plate 132, the piezoelectric actuator 133, the insulation plate 134a, the conductive plate 135 and the other insulation plate 134b are sequentially stacked, and as shown in fig. 2C and fig. 2D, the fluid actuator 13 is assembled on the carrier 11, and a channel 17 is maintained with the carrier 11, and the channel 17 is located at one side of the sensor 12, the fluid actuator 13 is driven to actuate the compressed air, flow is generated by flowing out of the channel 17, as indicated by the arrow shown in fig. 2D, to measure the air received by the sensor 12, thus allowing the fluid actuator 13 to direct air internally, and provide stable uniformity flow and directly introduce into sensor 12 department, let sensor 12 can acquire stable uniformity circulation of air direct monitoring, and shorten the monitoring reaction action time of sensor 12, reach accurate monitoring.

Referring to fig. 7, a driving and information transmission system of the air filter protector is shown, in which a power controller 15 of an actuation sensing device 1 stores and outputs energy to provide energy for measurement operation of a sensor 12 and actuation control of an actuator 13, the actuation sensing device 1 itself may not be provided with a power supply device, and an external power supply device 3 is further used to conduct energy to provide actuation of the driving sensor 12 and the actuator 13, so as to save the installation space of the whole module and achieve a miniaturized design trend.
