The movable portion 302b is provided around the hollow hole 302a in a region opposed to the confluence chamber 301c. The fixing portion 302 c is provided on the outer peripheral portion of the resonance sheet 302 and is fixed to the inflow plate 301.

Please continue to refer to FIGS. 9A, 9B and 10A. In the embodiment of the present invention, the piezoelectric actuator 303 includes a suspension plate 303a, an outer frame 303b, at least one bracket 303c, and a piezoelectric element 303d , At least a gap 303e and a convex portion 303f. In the embodiment of the present invention, the suspension board 303a has a square shape. The reason why the suspension board 303a adopts a square shape is that compared with the design of the circular suspension board, the structure of the square suspension board 303a has obvious advantages of power saving. The power consumption of a capacitive load operating at a resonant frequency will increase as the frequency rises, and because the resonant frequency of the square suspension plate 303a is significantly lower than that of a circular suspension plate, its relative power consumption is also significantly higher Low, so the square-shaped suspension plate 303a used in this case has the advantage of power saving. In the embodiment of the present invention, the outer frame 303b is disposed around the outer side of the suspension plate 303a, and at least one bracket 303c is connected between the suspension plate 303a and the outer frame 303b to provide elastic support for the suspension plate 303a. In the embodiment of the present invention, the piezoelectric element 303d has a side length that is less than or equal to one side length of the floating plate 303a. The piezoelectric element 303d is attached to a surface of the suspension plate 303a, and is used for applying a voltage to drive the suspension plate 303a to bend and vibrate. At least one gap 303e is formed between the floating plate 303a, the outer frame 303b and the at least one bracket 303c for the gas to pass through. The convex portion 303f is disposed on the opposite surface of the surface of the suspension plate 303a to which the piezoelectric element 303d is attached. In this embodiment, the convex portion 303f may be a body produced by performing an etching process on the suspension plate 303a A convex structure protruding on the surface opposite to the surface to which the piezoelectric element 303d is attached is formed.

Please continue to refer to FIG. 9A, FIG. 9B and FIG. 10A, the first insulating sheet 304, the conductive sheet 305 and the second insulating sheet 306 are all frame-shaped thin sheets, the inlet plate 301, the resonance sheet 302, The piezoelectric actuator 303, the first insulating sheet 304, the conductive sheet 305, and the second insulating sheet 306 are sequentially stacked to form the overall structure of the micropump 30. A chamber space 307 needs to be formed between the suspension plate 303a and the resonance plate 302. The cavity space 307 can be formed by filling a material between the resonant sheet 302 and the piezoelectric actuator 303 and the outer frame 303b, for example: conductive adhesive, but not limited thereto. It can maintain a certain depth between the resonance plate 302 and the suspension plate 303a to form the chamber space 307, which can guide the gas to flow more quickly, and because the suspension plate 303a and the resonance plate 302 maintain an appropriate distance, the contact interference is reduced, which promotes Noise generation can be reduced. In other embodiments, the thickness of the conductive paste filled between the resonance plate 302 and the piezoelectric actuator 303 outer frame 303b can be reduced by adding the height of the high voltage electric actuator 303 to the outer frame 303b. It can avoid that the conductive adhesive will expand and contract with the hot pressing temperature and cooling temperature to affect the actual spacing of the chamber space 307 after forming, and reduce the indirect impact of the hot pressing temperature and cooling temperature of the conductive adhesive on the overall structure assembly of the micro pump 30. But not limited to this. In addition, the depth of the chamber space 307 affects the transmission effect of the micropump 30, so maintaining a fixed depth of the chamber space 307 is very important for the micropump 30 to provide stable transmission efficiency.

As shown in FIG. 10B, in other embodiments, the suspension plate 303a may be stamped and formed to extend outward by a distance, and the outward extension distance may be formed at least one between the suspension plate 303a and the outer frame 303b The bracket 303c is adjusted so that the surface of the convex portion 303f on the suspension plate 303a and the surface of the outer frame 303b form a non-coplanar surface, and a small amount of filler material is applied to the assembled surface of the outer frame 303b, for example: conductive adhesive , The piezoelectric actuator 303 is bonded to the fixing portion 302c of the resonance sheet 302 by hot pressing, so that the piezoelectric actuator 303 can be combined with the resonance sheet 302 in combination. In this way, by directly stamping and forming the suspension plate 303a of the piezoelectric actuator 303 to form the structure of the chamber space 307, the required chamber space 307 can be stamped and formed by adjusting the suspension plate 303a of the piezoelectric actuator 303 The distance is completed, which effectively simplifies the structural design of the adjustment chamber space 307, and at the same time achieves the advantages of simplifying the process and shortening the process time.

It is worth noting that the inflow plate 301, the resonance sheet 302, the piezoelectric actuator 303, the first insulating sheet 304, the conductive sheet 305, and the second insulating sheet 306 can all be manufactured by the micro-electromechanical surface micro-machining technology, so that The volume of the micropump 30 is reduced to form a micropump of a microelectromechanical system.

In the embodiment of the present invention, the operation mode of the micropump 30 is shown in FIGS. 10C to 10E, please refer to FIG. 10C first, the piezoelectric element 303d of the piezoelectric actuator 303 is deformed and driven to float after being applied with a driving voltage The plate 303a is displaced away from the inlet plate 301. At this time, the volume of the chamber space 307 is increased, and a negative pressure is formed in the chamber space 307. Then, the gas in the confluence chamber 301c is drawn into the chamber space 307. The resonance plate 302 is synchronously displaced away from the inlet plate 301 due to the influence of the resonance principle, which increases the volume of the confluence chamber 301c, and the gas in the confluence chamber 301c enters the chamber space 307, causing the confluence chamber The inside of the chamber 301c is also in a negative pressure state, and the gas is sucked into the merge chamber 301c through the inflow hole 301a and the merge groove 301b. Referring again to FIG. 10D, the piezoelectric element 303d drives the suspension plate 303a to move closer to the inlet plate 301, compressing the chamber space 307. Similarly, the resonance plate 302 resonates with the suspension plate 303a and approaches the inlet plate 301 The displacement in the direction of synchronously pushes the gas in the chamber space 307 to transmit outward through at least one gap 303e to achieve the effect of transmitting the gas. Finally, referring to FIG. 10E, when the suspension plate 303a returns to the original position, the resonance plate 302 is still displaced away from the inlet plate 301 due to inertia. At this time, the resonance plate 302 will compress the chamber space 307 to make the chamber space 307 The gas inside moves in the direction of at least one gap 303e, and increases the volume in the confluence chamber 301c, so that the gas can continue to converge in the confluence chamber 301c through the inlet hole 301a and the confluence groove 301b. By continuously repeating the operation steps of the micro-pump 30 shown in FIGS. 10C to 10E, the micro-pump 30 can continuously flow the gas from the inflow hole 301a into the flow path formed by the inflow plate 301 and the resonance plate 302 and A pressure gradient is generated, and then is transmitted outward through at least one gap 303e, so that the gas flows at a high speed, so as to achieve the actuation operation of the micro-pump 30 to transmit the gas.

In the embodiment of the present invention, the number of the connecting pieces 401a is four, which are respectively adjacent to the 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 coupled to the suspension sheet 401b. The actuating body 403 is coupled to the cavity frame 402 and includes a piezoelectric carrier plate 403a, a tuning resonance plate 403b, and a piezoelectric plate 403c. The piezoelectric carrier plate 403a is coupled to the cavity frame 402, the tuning resonance plate 403b is coupled to the piezoelectric carrier plate 403a, and the piezoelectric plate 403c is coupled to the tuning resonance plate 403b. The piezoelectric plate 403c is deformed after being applied with a voltage, and drives the piezoelectric carrier plate 403a and the tuning resonance plate 403b to perform reciprocating bending vibration. The insulating frame 404 is coupled to the piezoelectric carrier 403a of the actuator 403, and the conductive frame 405 is coupled to the insulating frame 404. A resonance chamber 406 is formed between the actuating body 403, the cavity frame 402 and the suspension piece 401b.

Please refer to Fig. 12A to Fig. 12C for the operation mode of the blower box micro pump 40. Please refer to FIG. 11 and FIG. 12A first, the blower box micropump 40 is fixedly arranged through a plurality of connecting pieces 401a, and the air jet orifice 401 forms a gas flow chamber 407 at the bottom of the chamber accommodating the blower box micropump 40. Referring again to FIG. 12B, when a voltage is applied to the piezoelectric plate 403c of the actuating body 403, the piezoelectric plate 403c begins to deform due to the piezoelectric effect and simultaneously drives the tuning resonance plate 403b and the piezoelectric carrier plate 403a. At this time, the orifice 401 will be driven together by the principle of Helmholtz resonance, so that the actuating body 403 moves away from the bottom of the chamber housing the blower box micropump 40. Due to the displacement of the actuating body 403, the volume of the airflow chamber 407 increases, and the internal air pressure forms a negative pressure. Therefore, due to the pressure gradient, the gas outside the blower box micropump 40 is formed by the plurality of connecting pieces of the air jet orifice 401 The gap between 401a enters the airflow chamber 407 and collects pressure. Finally, referring to FIG. 12C, after the gas continuously enters the airflow chamber 407, the air pressure in the airflow chamber 407 forms a positive pressure. At this time, the actuating body 403 is driven by the voltage toward the micro-pump 40 containing the blower box. The direction of the bottom of the chamber moves. The volume of the airflow chamber 407 is thus compressed, and the gas in the airflow chamber 407 is pushed, so that the gas that enters the blower box micropump 40 is pushed and discharged to realize the transmission flow of the gas.

It is worth noting that the blower box micro-pump 40 can also be a micro-electro-mechanical system gas pump manufactured by a micro-electro-mechanical process. In other words, the air jet orifice 401, the cavity frame 402, the actuating body 403, the insulating frame 404, and the conductive frame 405 can all be made by surface micromachining technology to reduce the volume of the blower box micropump 40.

In addition, the design of the first gas compartment 221b and the second gas compartment 221c through the compartment body 221 can also prevent the gas sensor 223 from being affected by other components in the device, so that the gas monitoring machine 2 can detect anytime, anywhere The purpose is to have a fast and accurate monitoring effect.
