FIELD OF THE INVENTION

The present disclosure relates to an air pollution exchange method executed in a vehicle, and more particularly to a method of preventing air pollution in a vehicle.

BACKGROUND OF THE INVENTION

With the rapid development of the global population and industry, the air quality is deteriorating gradually. It is not only harmful to human health but also life-threatening in severe cases for people to expose in the harmful air pollution gases for a long time.

There are many pollutants in the air, such as carbon dioxide, carbon monoxide, formaldehyde, bacteria, fungi, volatile organic compound (VOC), suspended particulates or ozone, etc. which may be seriously harmful to human body as the concentration of pollutants increases. In the case of suspended particles, such fine particles might pass through the alveoli and circulate throughout the body with the blood and is not only harmful to the respiratory tract, but also might cause cardiovascular disease or increases the risk of cancer.

Nowadays, the prevalence of epidemic diseases, such as influenza and pneumonia, not only threatens people's health, but also restricts people's social activities, and the willingness to take public transportation has also decreased. As a result, driving by themselves has become the first choice of transportation when people need to go out. Therefore, how to make sure that the gas in the vehicle is clean and safe for people to breath at all times during driving by people becomes an important research and development topic of the present disclosure.

A resonance chamber5226is collaboratively defined by the actuator element5223, the chamber frame5222and the suspension plate5221a. A flowing chamber5227is formed between the gas-injection plate5221and the bottom surface of the gas-guiding-component loading region5215. The flowing chamber5227is in communication with the resonance chamber5226between the actuator element5223, the chamber frame5222and the suspension plate5221athrough the hollow aperture5221bof the gas-injection plate5221. By controlling the vibration frequency of the gas in the resonance chamber5226to be close to the vibration frequency of the suspension plate5221a, the Helmholtz resonance effect is generated between the resonance chamber5226and the suspension plate5221a, so as to improve the efficiency of gas transportation.

Please refer toFIG. 11B. When the piezoelectric plate5223cis moved away from the bottom surface of the gas-guiding-component loading region5215, the suspension plate5221aof the gas-injection plate5221is driven to move away from the bottom surface of the gas-guiding-component loading region5215by the piezoelectric plate5223c. In that, the volume of the flowing chamber5227is expanded rapidly, the internal pressure of the flowing chamber5227is decreased to form a negative pressure, and the gas outside the piezoelectric actuator522is inhaled through the vacant spaces5221cand enters the resonance chamber5226through the hollow aperture5221b. Consequently, the pressure in the resonance chamber5226is increased to generate a pressure gradient.

Furthermore as shown inFIG. 11C, when the suspension plate5221aof the gas-injection plate5221is driven by the piezoelectric plate5223cto move toward the bottom surface of the gas-guiding-component loading region5215, the gas in the resonance chamber5226is discharged out rapidly through the hollow aperture5221b, and the gas in the flowing chamber5227is compressed, thereby the converged gas is quickly and massively ejected out of the flowing chamber5227under the condition close to an ideal gas state of the Benulli's law, and transported to the ventilation hole5215aof the gas-guiding-component loading region5215.

In the embodiment, the gas-guiding-component loading region5215of the base521is in fluid communication with the gas-inlet groove5214, and the piezoelectric actuator522is accommodated in the square-shaped gas-guiding-component loading region5215of the base521. Moreover, the driving circuit board523covers the second surface5212of the base521, and the laser component524is positioned and disposed on the driving circuit board523, and is electrically connected to the driving circuit board523. The particulate sensor525is positioned and disposed on the driving circuit board523, and is electrically connected to the driving circuit board523. In that, when the outer cover526covers the base521, the inlet opening5261ais spatially corresponding to the gas-inlet5214aof the base521, and the outlet opening5261bis spatially corresponding to the gas-outlet5216aof the base521. By repeating the above operation steps shown inFIG. 11BandFIG. 11C, the piezoelectric plate5223cis driven to generate the bending deformation in a reciprocating manner According to the principle of inertia, since the gas pressure inside the resonance chamber5226is lower than the equilibrium gas pressure after the converged gas is ejected out, the gas is introduced into the resonance chamber5226again. Moreover, the vibration frequency of the gas in the resonance chamber5226is controlled to be close to the vibration frequency of the piezoelectric plate5223c, so as to generate the Helmholtz resonance effect to achieve the gas transportation at high speed and in large quantities.

Furthermore, as shown inFIG. 12A, the gas outside the gas detection module5is inhaled through the inlet opening5261aof the outer cover526, flows into the gas-inlet groove5214of the base521through the gas-inlet5214a, and is transported to the position of the particulate sensor525. The piezoelectric actuator522is enabled continuously to inhale the gas into the inlet path, and facilitate the gas outside the gas detection module to be introduced rapidly, flow stably, and transported above the particulate sensor525. Further as shown inFIG. 12B, a projecting light beam emitted from the laser component524passes through the transparent window5214bto irritate the suspended particles contained in the gas flowing above the particulate sensor525in the gas-inlet groove5214. When the suspended particles contained in the gas are irradiated and generate scattered light spots, the scattered light spots are received and calculated by the particulate sensor525for obtaining related information about the sizes and the concentration of the suspended particles contained in the gas. Moreover, the gas above the particulate sensor525is continuously driven and transported by the piezoelectric actuator522, flows into the ventilation hole5215aof the gas-guiding-component loading region5215, and is transported to the gas-outlet groove5216. As shown inFIG. 12C, When the gas flows into the gas outlet groove5216, the gas is detected through the gas sensor527. Since the gas is continuously transported into the gas outlet groove5216by the piezoelectric actuator522, the gas in the gas outlet groove5216is pushed to flow through the gas-outlet5216aand the outlet opening5261band discharged out.

In that, the air pollution is inhaled into the inlet path defined by the gas-inlet groove5214through the inlet opening5261a, and passes through the particulate sensor525to detect the particle concentration of the suspended particles contained in the air pollution. Furthermore, the air pollution transported by the piezoelectric actuator522flows through the ventilation hole5215aof the gas-guiding-component loading region5215, enters the outlet path defined by the gas-outlet groove5216, passes through the gas sensor527for detecting, and then is discharged through the gas-outlet5216aof the base521the outlet opening5261b.
