Upon receiving the driving signal (driving frequency and driving voltage), the piezoelectric plate 1123c deforms due to the piezoelectric effect, and further drives the piezoelectric carrier 1123a and the tuning resonator 1123b to generate reciprocating flexural vibration.

As described above, the adjustment resonance plate 1123b is located between the piezoelectric plate 1123c and the piezoelectric carrier plate 1123a, and the vibration frequency of the piezoelectric carrier plate 1123a can be adjusted as a buffer therebetween. Basically, the thickness of the tuning resonant plate 1123b is greater than the thickness of the piezoelectric carrier plate 1123a, and the thickness of the tuning resonant plate 1123b is variable, thereby tuning the vibration frequency of the actuator 1123.

Referring to fig. 6A, 6B and 7A, the air hole plate 1121, the cavity frame 1122, the actuating body 1123, the insulating frame 1124 and the conductive frame 1125 are sequentially stacked and positioned in the air guide assembly bearing region 1115, so that the piezoelectric actuator 112 is supported and positioned in the air guide assembly bearing region 1115 and supported and positioned on the positioning protrusion 1115B with the bottom, and thus a gap 1121c is defined between the suspension plate 1121a and the inner edge of the air guide assembly bearing region 1115 for air circulation.

Referring to fig. 7A, an airflow chamber 1127 is formed between the air hole plate 1121 and the bottom surface of the air guide member supporting area 1115. The gas flow chamber 1127 communicates with the resonance chamber 1126 between the actuator 1123, the gas orifice plate 1121, and the suspension plate 1121a through the hollow hole 1121b of the gas orifice plate 1121, and the resonance chamber 1126 and the suspension plate 1121a generate a helmholtz resonance effect (Helmholtz resonance) by controlling the vibration frequency of the gas in the resonance chamber 1126 so as to approach the same vibration frequency as the suspension plate 1121a, thereby improving the gas transmission efficiency.

Referring to fig. 7B, when the piezoelectric plate 1123c moves away from the bottom surface of the air guide member carrying area 1115, the piezoelectric plate 1123c drives the suspension plate 1121a of the air jet hole plate 1121 to move away from the bottom surface of the air guide member carrying area 1115, so that the volume of the air flow chamber 1127 is suddenly expanded, the internal pressure thereof is reduced to form a negative pressure, and the air outside the piezoelectric actuator 112 is sucked to flow in from the gap 1121c and enter the resonance chamber 1126 through the hollow hole 1121B, so that the air pressure in the resonance chamber 1126 is increased to generate a pressure gradient; as shown in fig. 7C, when the piezoelectric plate 1123C drives the suspension plate 1121a of the air hole plate 1121 to move toward the bottom surface of the air guide member carrying region 1115, the air in the resonance chamber 1126 flows out rapidly through the hollow hole 1121b, presses the air in the air flow chamber 1127, and causes the converged air to be ejected into the air vent 1115a of the air guide member carrying region 1115 rapidly and in large quantity in an ideal air state approaching bernoulli's law. Accordingly, by repeating the operations of fig. 7B and 7C, the piezoelectric plate 1123C is vibrated in a reciprocating manner, and the gas is guided to enter the resonant chamber 1126 again by the air pressure in the resonant chamber 1126 after the air is exhausted being lower than the balance air pressure according to the principle of inertia, so that the vibration frequency of the gas in the resonant chamber 1126 is controlled to be close to the same as the vibration frequency of the piezoelectric plate 1123C, thereby generating the helmholtz resonance effect, and realizing the high-speed and large-scale transmission of the gas.

Referring to fig. 8A, gases all enter through the inlet 1161a of the cover 116, enter the inlet channel 1114 of the base 111 through the inlet 1114a, and flow to the sensor 115. As shown in fig. 8B, the piezoelectric actuator 112 continuously drives the gas that is sucked into the gas inlet path, so that the external gas is rapidly introduced and stably flows and passes through the upper portion of the sensor 115, at this time, the laser component 114 emits a light beam into the gas inlet groove 1114 through the light-transmitting window 1114B, the gas inlet groove 1114 irradiates the suspended particles contained therein through the gas above the sensor 115, when the irradiated light beam contacts the suspended particles, the scattered light beam is scattered and generates a projected light spot, the sensor 115 receives the projected light spot generated by the scattering and calculates to obtain the information about the particle size and concentration of the suspended particles contained in the gas, and the gas above the sensor 115 is continuously transmitted by the piezoelectric actuator 112 and is introduced into the vent 1115a of the gas guide component carrying area 1115, and enters the first section 1116B of the gas outlet groove 1116.
