The suspension plate 303a is in a square shape, and the suspension plate 303a is square, so compared with the design of a circular suspension plate, the structure of the square suspension plate 303a obviously has the advantage of power saving, because of the capacitive load operated under the resonant frequency, the consumed power of the square suspension plate 303a is increased along with the rise of the frequency, and because the resonant frequency of the square suspension plate 303a is obviously lower than that of the circular suspension plate, the relative consumed power is also obviously lower, namely the square suspension plate 303a adopted in the scheme has the benefit of power saving; the outer frame 303b is disposed around the outer side of the suspension plate 303 a; at least one bracket 303c is connected between the suspension plate 303a and the outer frame 303b to provide a supporting force for elastically supporting the suspension plate 303 a; and a piezoelectric element 303d having a side length less than or equal to a suspension plate side length of the suspension plate 303a, and the piezoelectric element 303d is attached to a surface of the suspension plate 303a for applying a voltage to drive the suspension plate 303a to vibrate in a bending manner; at least one gap 303e is formed between the suspension plate 303a, the outer frame 303b and the bracket 303c for air to pass through; the protrusion 303f is disposed on the other surface of the suspension plate 303a opposite to the surface to which the piezoelectric element 303d is attached, and in this embodiment, the protrusion 303f is a protrusion integrally formed on the other surface of the suspension plate 303a opposite to the surface to which the piezoelectric element 303d is attached by using an etching process.

In addition, the chamber space 307 will affect the delivery performance of the actuation pump 30, so it is important to maintain a fixed chamber space 307 to provide stable delivery efficiency for the actuation pump 30.

Thus, in another embodiment of the piezoelectric actuator 303 shown in fig. 4B, the suspension plate 303a may be formed by stamping to extend outwardly by a distance adjusted by at least one support 303c formed between the suspension plate 303a and the frame 303B, such that the surface of the protrusion 303f on the suspension plate 303a and the surface of the frame 303B are not coplanar, and a small amount of filling material is applied to the mating surface of the frame 303B, for example: the conductive adhesive is used for adhering the piezoelectric actuator 303 to the fixing portion 302c of the resonator plate 302 in a hot-pressing manner, so that the piezoelectric actuator 303 can be assembled and combined with the resonator plate 302, and thus, the structural improvement of forming a cavity space 307 by stamping the suspension plate 303a of the piezoelectric actuator 303 is directly adopted, and the required cavity space 307 can be completed by adjusting the stamping forming distance of the suspension plate 303a of the piezoelectric actuator 303, thereby effectively simplifying the structural design of adjusting the cavity space 307, simultaneously achieving the advantages of simplifying the manufacturing process, shortening the manufacturing time and the like.

The air hole plate 421 is made of a flexible material, and includes a suspension plate 4210 and a hollow hole 4211. The suspension plate 4210 is a plate-shaped structure capable of bending and vibrating, and the shape and size of the suspension plate 4210 approximately correspond to the inner edge of the air guide assembly carrying area 415, but not limited thereto, and the shape of the suspension plate 4210 may be one of square, circle, ellipse, triangle and polygon; the hollow hole 4211 penetrates the center of the suspension plate 4210 to allow gas to flow.

The cavity frame 422 is stacked on the air injection hole plate 421, and the shape thereof corresponds to the air injection hole plate 421. The actuating body 423 is stacked on the cavity frame 422, and defines a resonant cavity 426 with the cavity frame 422 and the suspension plate 4210. An insulating frame 424 is stacked on the actuating body 423 and has an appearance similar to that of the chamber frame 422.

The piezoelectric plate 4233 bears and is superposed on the tuning resonator plate 4232. The tuning resonator plate 4232 and the piezoelectric plate 4233 are accommodated in the insulating frame 424, and are electrically connected to the piezoelectric plate 4233 via the conductive electrode 4252 of the conductive frame 425. The piezoelectric carrier 4231 and the tuning resonator plate 4232 are made of conductive materials, the piezoelectric carrier 4231 has a piezoelectric pin 4234, the piezoelectric pin 4234 and the conductive pin 4251 are connected to a driving circuit (not shown) on the driving circuit board 43 to receive a driving signal (driving frequency and driving voltage), the driving signal forms a loop by the piezoelectric pin 4234, the piezoelectric carrier 4231, the tuning resonator plate 4232, the piezoelectric plate 4233, the conductive electrode 4252, the conductive frame 425 and the conductive pin 4251, and the insulating frame 424 separates the conductive frame 425 and the actuator 423 to avoid short circuit, so that the driving signal is transmitted to the piezoelectric plate 4233. After receiving the driving signal (driving frequency and driving voltage), the piezoelectric plate 4233 deforms due to the piezoelectric effect, thereby further driving the piezoelectric carrier plate 4231 and adjusting the resonator plate 4232 to generate reciprocating bending vibration.

As described above, the tuning resonator plate 4232 is located between the piezoelectric plate 4233 and the piezoelectric carrier plate 4231, and serves as a buffer between the two, thereby tuning the vibration frequency of the piezoelectric carrier plate 4231. Basically, the thickness of the tuning resonance plate 4232 is larger than the thickness of the piezoelectric carrier plate 4231, and the thickness of the tuning resonance plate 4232 is varied, thereby tuning the vibration frequency of the actuating body 423.

Referring to fig. 9A, 9B and 10A, the air injection hole plate 421, the cavity frame 422, the actuating body 423, the insulating frame 424 and the conductive frame 425 are stacked and positioned in the air guide device supporting region 415, so that the piezoelectric actuator 42 is supported and positioned in the air guide device supporting region 415, and is supported and positioned by the positioning bumps 415B, and thus the piezoelectric actuator 42 defines a gap 4212 between the suspension plate 4210 and the inner edge of the air guide device supporting region 415 for air circulation.

Referring to fig. 10A, an air flow chamber 427 is formed between the air injection hole 421 and the bottom surface of the air guide supporting region 415. The gas flow chamber 427 communicates with the resonance chamber 426 among the actuating body 423, the cavity frame 422 and the floating plate 4210 through the hollow holes 4211 of the gas injection hole plate 421, and the resonance chamber 426 and the floating plate 4210 generate a Helmholtz resonance effect (Helmholtz resonance) by controlling the vibration frequency of the gas in the resonance chamber 426 to be approximately the same as the vibration frequency of the floating plate 4210, so that the gas transmission efficiency is improved.

As shown in fig. 10B, when the piezoelectric plate 4233 moves away from the bottom surface of the air guide assembly supporting area 415, the piezoelectric plate 4233 drives the suspension plate 4210 of the air injection hole plate 421 to move away from the bottom surface of the air guide assembly supporting area 415, so that the volume of the air flow chamber 427 is expanded sharply, the internal pressure thereof is reduced to form a negative pressure, and the air outside the piezoelectric actuator 42 is sucked to flow from the gap 4212 and enter the resonance chamber 426 through the hollow hole 4211, so that the air pressure in the resonance chamber 426 is increased to generate a pressure gradient; as shown in fig. 10C, when the piezoelectric plate 4233 drives the suspension plate 4210 of the gas injection hole plate 421 to move toward the bottom surface of the gas guide module bearing area 415, the gas in the resonance chamber 426 flows out rapidly through the hollow hole 4211, the gas in the gas flow chamber 427 is squeezed, and the converged gas is rapidly and massively injected into the vent holes 415a of the gas guide module bearing area 415 in a state close to the ideal gas state of bernoulli's law. Therefore, by repeating the operations of fig. 10B and 10C, the piezoelectric plate 4233 can vibrate in a reciprocating manner, and according to the principle of inertia, when the internal gas pressure of the exhausted resonant chamber 426 is lower than the equilibrium gas pressure, the gas is guided into the resonant chamber 426 again, so that the vibration frequency of the gas in the resonant chamber 426 and the vibration frequency of the piezoelectric plate 4233 are controlled to be approximately the same, so as to generate the helmholtz resonance effect, thereby realizing high-speed and large-volume transmission of the gas.

As shown in fig. 11A, the gas enters from the inlet frame opening 461A of the cover 46, enters the inlet groove 414 of the base 41 through the inlet port 414a, and flows to the position of the particle sensor 45.

Finally, as shown in fig. 11C, after the gas enters the first section 416b of the gas outlet trench 416, since the piezoelectric actuator 42 continuously delivers the gas into the first section 416b, the gas in the first section 416b will be pushed to the second section 416C, and finally discharged through the gas outlet 416a and the gas outlet 461 b.
