Among them, the hoverboard 303a is a square shape. The reason why the hoverboard 303a adopts a square shape is that compared with the design of a circular hoverboard, the structure of the square hoverboard 303a obviously has the advantage of saving power, because it operates under the resonant frequency. For capacitive loads, the power consumption will increase with the increase of the frequency, and because the resonance frequency of the square suspension board 303a is obviously lower than that of the circular suspension board, its relative power consumption is also significantly lower, that is, the used in this case The suspension board 303a of square design has the advantage of saving electricity; the outer frame 303b is arranged around the outside of the suspension board 303a; at least one bracket 303c is connected between the suspension board 303a and the outer frame 303b to provide elastic support for the suspension board 303a Support force; and a piezoelectric element 303d has a side length, the side length is less than or equal to the side length of the suspension plate 303a, and the piezoelectric element 303d is attached to a surface of the suspension plate 303a for being applied with voltage to drive the suspension The plate 303a bends and vibrates; and at least one gap 303e is formed between the suspension plate 303a, the outer frame 303b and the support 303c for the passage of gas; On the other surface, the protrusion 303f in this embodiment can be a protrusion protruding from the other surface opposite to the surface on which the piezoelectric element 303d is attached, which is integrally formed by performing an etching process on the suspension plate 303a. shape structure.

The cavity space 307 can be formed by filling a material between the resonant plate 302 and the outer frame 303b of the piezoelectric actuator 303, such as: conductive glue, but not limited thereto, so that the space between the resonant plate 302 and the suspension plate 303a A certain depth can be maintained between them to form a chamber space 307, which can guide the gas to flow more quickly, and because the suspension plate 303a and the resonant plate 302 keep an appropriate distance to reduce the contact and interference with each other, so that the noise generation can be reduced. Of course, in the embodiment, the thickness of the conductive glue filled between the resonant sheet 302 and the piezoelectric actuator 303 outer frame 303b can also be reduced by increasing the height of the piezoelectric actuator 303 outer frame 303b, so First, it can prevent the thermal expansion and contraction of the conductive adhesive with the hot-pressing temperature and cooling temperature from affecting the actual spacing of the cavity space 307 after molding, and reduce the indirect influence of the hot-pressing temperature and cooling temperature of the conductive adhesive on the overall structure assembly of the micropump 30. influence, but not limited to. In addition, the chamber space 307 will affect the transmission effect of the micropump 30 , so maintaining a fixed chamber space 307 is very important for the micropump 30 to provide stable transmission efficiency.

Therefore, as shown in FIG. 8B , in other embodiments of the piezoelectric actuator 303, the suspension plate 303a can be stamped and formed to extend outward for a distance, and the outward extension distance can be determined by forming the suspension plate 303a and the outer frame. At least one bracket 303c between 303b is adjusted so that the surface of the convex part 303f on the suspension board 303a and the surface of the outer frame 303b form a non-coplanar surface, and is used to coat a small amount of filling on the assembly surface of the outer frame 303b Material, such as: conductive glue, the piezoelectric actuator 303 is attached to the fixed part 302c of the resonant plate 302 by means of hot pressing, so that the piezoelectric actuator 303 can be combined with the resonant plate 302, so that the The suspension plate 303a of the above-mentioned piezoelectric actuator 303 is used for stamping to form a structural improvement of a cavity space 307, and the required cavity space 307 can be adjusted by adjusting the stamping distance of the suspension plate 303a of the piezoelectric actuator 303 This effectively simplifies the structural design of the adjustment chamber space 307, and also achieves the advantages of simplifying the manufacturing process and shortening the manufacturing process time. In addition, the first insulating sheet 304 , the conductive sheet 305 and the second insulating sheet 306 are frame-shaped thin sheets, which are sequentially stacked on the piezoelectric actuator 303 to form the overall structure of the micropump 30 .

In order to understand the output actuation mode of the above-mentioned micropump 30 for gas transmission, please continue to refer to FIG. 8C to FIG. 8E . Please refer to FIG. 8C first. The piezoelectric element 303d of the piezoelectric actuator 303 is deformed after being applied with a driving voltage to drive the suspension plate 303a to move downward. At this time, the volume of the chamber space 307 is increased, forming a The negative pressure draws the gas in the confluence chamber 301c into the chamber space 307, and at the same time, the resonance plate 302 is affected by the resonance principle and moves downward synchronously, which increases the volume of the confluence chamber 301c, and because the confluence chamber 301c The gas in the chamber enters the chamber space 307, causing the confluence chamber 301c to be in a negative pressure state, and then the gas is sucked into the confluence chamber 301c through the inlet hole 301a and the confluence row groove 301b; please refer to FIG. 8D again, The piezoelectric element 303d drives the suspension plate 303a to move upwards, compressing the chamber space 307. Similarly, the resonator plate 302 moves upward due to resonance with the suspension plate 303a, forcing the gas in the chamber space 307 to be simultaneously pushed downward through the gap 303e to Down transmission to achieve the effect of gas transmission; finally please refer to Figure 8E, when the suspension plate 303a returns to its original position, the resonant plate 302 is still displaced downward due to inertia, and the resonant plate 302 at this time will make the compression chamber space 307 The gas moves to the gap 303e and increases the volume of the confluence chamber 301c, so that the gas can continuously pass through the inlet hole 301a and the confluence row groove 301b to converge in the confluence chamber 301c. By continuously repeating the action steps of the gas transmission provided by the micropump 30 shown in FIG. 8C to FIG. 8E , the micropump 30 can make the gas continuously enter the flow formed by the inlet plate 301 and the resonant plate 302 from the inlet hole 301a. and generate a pressure gradient, and then transmit downwards through the gap 303e, so that the gas flows at a high speed, so as to achieve the actuation operation of the micropump 30 to transmit the gas output.

Please continue to refer to FIG. 8A, the inlet plate 301, the resonance plate 302, the piezoelectric actuator 303, the first insulating plate 304, the conductive plate 305 and the second insulating plate 306 of the micropump 30 can all pass through the surface of the micro-electromechanical machine. The micro-machining process reduces the volume of the micro-pump 30 to form a micro-electro-mechanical system micro-pump.

Certainly, the gas actuator 224 in this case may not only have the structure of the above-mentioned micropump 30, but also may be a structure and operation method of a blower box micropump 40 to implement gas transmission. Please refer to FIG. 9 , and FIG. 10A to FIG. 10C , the blower box micropump 40 includes an air injection orifice sheet 401 , a cavity frame 402 , an actuating body 403 , an insulating frame 404 and a conductive frame 405 stacked in sequence. The air jet hole plate 401 includes a plurality of connecting pieces 401a, a suspension piece 401b and a hollow hole 401c. The suspension piece 401b can bend and vibrate, and the multiple connection pieces 401a are adjacent to the periphery of the suspension piece 401b. In this embodiment, the number of connecting elements 401a is four, which are respectively adjacent to four corners of the suspension piece 401b, but it is not limited thereto. The hollow hole 401c is formed at the center of the suspension piece 401b. The cavity frame 402 is carried and stacked on the suspension sheet 401b. The actuating body 403 is loaded and stacked on the cavity frame 402, and includes a piezoelectric carrier plate 403a, an adjustment resonant plate 403b, and a piezoelectric plate 403c, wherein the piezoelectric carrier plate 403a is loaded and stacked on the cavity frame 402, the adjustment resonant plate 403b is loaded and stacked on the piezoelectric carrier plate 403a, and the piezoelectric plate 403c is loaded and stacked on the adjusted resonance plate 403b for deformation after being applied with voltage to drive the piezoelectric carrier plate 403a and The resonance plate 403b is adjusted to perform reciprocating bending vibration. The insulating frame 404 is carried on the piezoelectric carrier plate 403a of the actuating body 403, and the conductive frame 405 is carried and stacked on the insulating frame 404. A resonance chamber 406 is formed.

Please refer to FIG. 10A to FIG. 10C , which are schematic diagrams of the operation of the blower box micropump 40 in this case. Please refer to Fig. 9 and Fig. 10A first, the blower box micro-pump 40 is fixedly installed through a plurality of connecting pieces 401a, and an air flow chamber 407 is formed at the bottom of the air injection hole 401; please refer to Fig. 10B again, when a voltage is applied to the actuating body 403 When the piezoelectric plate 403c is formed, the piezoelectric plate 403c begins to deform due to the piezoelectric effect and synchronously drives and adjusts the resonant plate 403b and the piezoelectric carrier plate 403a. The principle is driven together, so that the actuating body 403 moves upward. Due to the upward displacement of the actuating body 403, the volume of the airflow chamber 407 on the bottom surface of the air-jet hole sheet 401 increases, and the internal air pressure forms a negative pressure, and the gas outside the blower box micropump 40 will be driven by the gas-jet hole sheet 401 due to the pressure gradient. The gap of the connecting piece 401a enters the airflow chamber 407 and collects pressure; finally please refer to FIG.
