Referring to fig. 1 and 2, one embodiment of the method of the present invention is described as follows, the method of the present invention includes: a plurality of gas detection devices 1a, 1b, 1c, and 1d, a coupling device 2, and a

multi-filtration purification device

3a, 3b, 3c, and 3d are disposed in each indoor space. For the purpose of describing the present embodiment in detail, the area around the gas detection device 1a and the filtration purification device 3a is defined as an area a, the area around the gas detection device 1B and the filtration purification device 3B is defined as an area B, the area around the gas detection device 1C and the filtration purification device 3C is defined as an area C, and the area around the gas detection device 1D and the filtration purification device 3D is defined as an area D, so that the gas pollution data of each area A, B, C, D is detected and outputted to the connection device 2.

The connection device 2 is used for receiving and comparing the gas pollution data detected by the plurality of gas detection devices 1a, 1b, 1c, 1d to perform intelligent operation, so as to find out the position of the area location L with gas pollution in the indoor space of the area A, B, C, D, and intelligently selects to send out a first control command to be transmitted to the filtering and

purifying devices

Watch 1

Further explaining the method for detecting and filtering indoor gas pollution, the connecting device 2 of the present invention intelligently calculates the area position L of gas pollution by a three-point positioning method. First, the positioning positions (e.g. 1a, 1b, 1c) of any three gas detection devices are found, and the distances between the positions of the three gas detection devices 1a, 1b, 1c and the gas pollution can be found by using the gas detection devices 1a, 1b, 1c as the centers of circles, so as to calculate the region position L of the gas pollution. For example, in the above table one, the location L of the gas contaminated area is located in the area C of the indoor space and the data is 30.00, so that the data measured by the gas detecting device 1C closest to the location L of the gas contaminated area is the highest 6.69, the data measured by the gas detecting device 1b farthest from the location L of the gas contaminated area is 1.07, and the data measured by the remaining two gas detecting devices 1a and 1d are 2.72 and 2.63, respectively. Therefore, the positions of the three gas detecting devices 1a, 1b, and 1c are respectively used as the center of circle, and the data 2.72, 1.07, and 6.69 measured by the three gas detecting devices 1a, 1b, and 1c are used as the reference to calculate the distance between the three gas detecting devices 1a, 1b, and 1c and the location L of the area contaminated with gas, and when the locations of the three gas detecting devices 1a, 1b, and 1c are known and the distances between the area L contaminated with gas and the three gas detecting devices 1a, 1b, and 1c are calculated, the location L of the area contaminated with gas can be calculated as the location of the area contaminated with gas by three-point positioning. The method of three-point positioning is a preferred embodiment of the present invention, but not limited thereto, that is, the location L of the gas-polluted area can be calculated by using the method of three-point positioning.

In this embodiment, the gas detection devices 1a, 1b, 1c, and 1d may be fixed or mobile, and the connection device 2 may be a mobile device 2a or a cloud processing device 2 b.

When the connecting device 2 of the present invention calculates the location L of the area polluted by the gas in the area C of the indoor space through the intelligent operation, the connecting device 2 sends a first control command to the filtering and purifying device 3C nearest to the location L of the area polluted by the gas to receive and start the filtering and purifying device, and then the connecting device 2 sends a second control command to the other three filtering and

purifying devices

3a, 3b and 3d to receive and start the filtering and purifying device to filter and purify the gas, so as to accelerate the filtering and purifying of the gas and promote the indoor space to form a clean and safe breathable gas state.

purifying devices

3a, 3b, 3c, and 3d each include a wind guide 21 and a filtering and purifying module 22, wherein the wind guide 21 guides the gas pollution to pass through the filtering and purifying module 22 for filtering and purifying. The air guide 21 can be a fan, a cleaner, an air conditioner, or a fresh air machine. And the space volume of each of the

filter purification devices

3a, 3b, 3c, and 3d in the region A, B, C, D of the indoor space is 16.5 to 247.5m ³ At least 1-75 Air guiding devices 21 are installed in the indoor space, and the Clean Air output ratio (CADR) of the Air guiding devices 21 of the filtering and

In the preferred embodiment of the present invention, the piezoelectric carrier 1223a and the tuning resonator 1223b are made of conductive materials. The piezoelectric carrier 1223a has a piezoelectric pin 1223d, and the piezoelectric pin 1223d and the conductive pin 1225a are connected to a driving circuit (not shown) on the driving circuit board 123 to receive a driving signal (which may be a driving frequency and a driving voltage), where the piezoelectric pin 1223d, the piezoelectric carrier 1223a, the tuning resonator plate 1223b, the piezoelectric plate 1223c, the conductive electrode 1225b, the conductive frame 1225, and the conductive pin 1225a form a loop, and the insulating frame 1224 separates the conductive frame 1225 from the actuator 1223 to avoid short-circuit, so that the driving signal is transmitted to the piezoelectric plate 1223 c. After receiving the driving signal, the piezoelectric plate 1223c deforms due to the piezoelectric effect, and further drives the piezoelectric carrier plate 1223a and the tuning resonator plate 1223b to generate a reciprocating bending vibration.

To explain, the tuning resonator plate 1223b is disposed between the piezoelectric plate 1223c and the piezoelectric carrier plate 1223a, and serves as a buffer therebetween, so as to tune the vibration frequency of the piezoelectric carrier plate 1223 a. Basically, the tuning resonator plate 1223b has a thickness greater than that of the piezoelectric carrier plate 1223a, and the frequency of vibration of the actuator 1223 is tuned by changing the thickness of the tuning resonator plate 1223 b. The air hole plate 1221, the chamber frame 1222, the actuator 1223, the insulating frame 1224, and the conductive frame 1225 are sequentially stacked and positioned in the air guide unit bearing area 1215, such that the piezoelectric actuator 122 is positioned in the air guide unit bearing area 1215, and the piezoelectric actuator 122 defines a gap 1221c between the floating plate 1221a and the inner edge of the air guide unit bearing area 1215 for air circulation.

An airflow chamber 1227 is formed between the air injection hole 1221 and the bottom surface of the air guide unit loading area 1215. The air flow chamber 1227 is communicated with the resonance chamber 1226 among the actuating body 1223, the air injection hole piece 1221 and the floating piece 1221a through the hollow holes 1221b of the air injection hole piece 1221, and the vibration frequency of the air in the resonance chamber 1226 is made to be approximately the same as the vibration frequency of the floating piece 1221a, so that the resonance chamber 1226 and the floating piece 1221a can generate a Helmholtz resonance effect (Helmholtz resonance) to improve the transmission efficiency of the air. When the piezoelectric plate 1223c moves away from the bottom surface of the gas guide unit carrying area 1215, the piezoelectric plate 1223c moves the suspension piece 1221a of the orifice piece 1221 away from the bottom surface of the gas guide unit carrying area 1215, so that the volume of the gas flow chamber 1227 is abruptly expanded, the internal pressure is decreased to generate a negative pressure, the gas outside the suction piezoelectric actuator 122 flows into the resonance chamber 1226 through the hollow orifice 1221b from the air gap 1221c, and the gas pressure in the resonance chamber 1226 is increased to generate a pressure gradient. When the piezoelectric plate 1223c moves the floating piece 1221a of the air injection hole piece 1221 toward the bottom surface of the gas guide module bearing section 1215, the gas in the resonance chamber 1226 rapidly flows out through the hollow hole 1221b, presses the gas in the gas flow chamber 1227, and causes the collected gas to be rapidly and largely ejected out of the air holes 1215a of the gas guide module bearing section 1215 in a state close to the ideal gas state of the bernoulli's law.

By repeating the operations shown in fig. 10B and 10C, the piezoelectric plate 1223C vibrates in a reciprocating manner, and according to the principle of inertia, when the air pressure inside the exhausted resonant chamber 1226 is lower than the equilibrium air pressure, the air is guided into the resonant chamber 1226 again, so that the vibration frequency of the air in the resonant chamber 1226 and the vibration frequency of the piezoelectric plate 1223C are controlled to be approximately the same, so as to generate the helmholtz resonance effect, and achieve high-speed and large-volume transmission of the air.

Referring to FIGS. 11A-11C, gas enters through the inlet port 1214a of the cover 126, enters the inlet channel 1214 of the base 121 through the inlet port 1214a, and flows to the particle sensor 125. Furthermore, the piezoelectric actuator 122 continuously drives the gas sucking the gas path to facilitate the rapid introduction and stable circulation of the external gas, and passes through the upper portion of the particle sensor 125, the laser assembly 124 emits a light beam into the gas inlet channel 1214 through the light-transmitting window 1214b, the gas inlet channel 1214 passes through the upper portion of the particle sensor 125, when the light beam of the particle sensor 125 irradiates the aerosol in the gas, a scattering phenomenon and a projected light spot are generated, when the projected light spot generated by scattering is received by the particle sensor 125, calculation is performed to obtain information about the particle size and concentration of the aerosol contained in the gas, and the gas above the particle sensor 125 is continuously driven by the piezoelectric actuator 122 to be introduced into the gas vent 1215a of the gas guide module bearing area 1215 and enter the gas outlet channel 1216. Finally, when the gas enters the gas outlet trench 1216, the gas in the gas outlet trench 1216 is pushed and exhausted to the outside through the gas outlet port 1216a and the gas outlet frame port 1261b because the piezoelectric actuator 122 continuously transmits the gas into the gas outlet trench 1216.
