Description

CROSS-REFERENCE TO RELATED APPLICATION

This application claims priority to Taiwan Patent Application No. 112128190, filed on Jul. 27, 2023. The entire contents of the above-mentioned patent application are incorporated herein by reference for all purposes.

FIELD OF THE INVENTION

The present disclosure relates to an indoor air pollution prevention system, and more particularly to an indoor air pollution prevention system suitable for various indoor fields.

BACKGROUND OF THE INVENTION

Suspension particles are solid particles or droplets within the gas. Since the suspension particles are extremely fine, it is often that the suspension particles are inhaled into the lung by passing through the nose hair inside the nasal cavity of human's body. As a result, inflammation of the lungs, asthma or cardiovascular diseases are caused. Furthermore, if the suspension particles are attached with other pollutants, it will be more harmful to the respiratory system of human's body. Recently, the problem of the gas pollution is getting worse, especially, the concentration data of fine suspended particles, e.g., PM2.5, is often too high. Therefore, the detection of the concentration of the suspension particles is getting more attention. However, since the gas flows unstably owing to the wind direction and air volume, and the conventional air quality monitoring stations used for detecting the suspension particles are fixedly disposed at certain locations, people cannot check the concentration of the suspension particles in the surrounding environment.

Moreover, people pay more attention to the quality of the air around their lives. For example, carbon monoxide, carbon dioxide, volatile organic compounds (VOC), PM2.5, nitric oxide, sulfur monoxide and even the suspended particles contained in the air are exposed in the environment to affect the human health, and even endanger the life seriously. Therefore, the quality of environmental air has attracted the attention of various countries. How to detect the air quality and avoid the harm from the area with poor air quality is a problem that urgently needs to be solved.

In order to confirm the quality of the air, it is feasible to use a gas detector to detect the air surrounding in the environment. If the detection information is provided in real time to warn the people in the environment, it is helpful of avoiding the harm and facilitates the people to escape the hazard immediately. Thus, it prevents the hazardous gas exposed in the environment from affecting the human health and causing the harm. Therefore, it is a very good application to use a gas detector to detect the air in the surrounding environment.

However, it is not easy to control the indoor air quality. In addition to the air quality of the outdoor space, the air environmental conditions and pollution sources are the major factors that affect indoor air quality. There is needs of intelligently and quickly detecting the indoor air pollution sources in various indoor field, effectively removing the indoor air pollution to form a clean and safe breathing gas state, instantly monitoring the indoor air quality anytime and anywhere, and quickly purifying the indoor air when the indoor air quality is poor. The main subjects of research and development of the disclosure are to intelligently generate an air convection in the indoor space, quickly detect and determine the location of air pollution field, use the location to effectively control multiple filtering devices to implement the intelligent air convection to accelerate the directional flow of the air pollution, filter and remove the indoor air pollution sources, and make the indoor air pollution treatment of positioning the air pollution positioning-guiding the air pollution guiding-purifying the air pollution completely, whereby a clean and safe breathing gas state is achieved.

SUMMARY OF THE INVENTION

One object of the present disclosure is to provide an indoor air pollution prevention system. Since the indoor air pollution occurs and moves at any time, the indoor air pollution prevention system of the present disclosure includes a plurality of gas detectors arranged in various indoor fields and outdoor field. With the arrangement, the gas detector determines a characteristic, a concentration and a location of an air pollution, and outputs to form air pollution data. Furthermore, the gas exchange device includes an intake channel communicated to an intake filter device and an exhaust channel communicated to an exhaust filter device. The cloud computing service device receives the air pollution data detected in the indoor field unit and the outdoor field unit, stores the air pollution data in an air pollution database, implements an artificial intelligence calculation to determine the location of the air pollution, and issues a control command to the intake filter device and the exhaust filter device to control activation operations of the intake filter device and the exhaust filter device. In that, the indoor gas and the outdoor gas are intelligently selected for exchange, and a directional airflow is generated in the indoor field unit to quickly guide the air pollution to the filter element for filtering and removal completely.

In the embodiment, the laser component 324 and the particulate sensor 325 are disposed on and electrically connected to the driving circuit board 323 and located within the base 321. In order to clearly describe and illustrate the positions of the laser component 324 and the particulate sensor 325 in the base 321, the driving circuit board 323 is intentionally omitted.

In addition, the laser component 324 is spatially corresponding to the transparent window 3214b, therefore, a light beam emitted by the laser component 324 passes through the transparent window 3214b and is irradiated into the gas-inlet groove 3214. A light beam path emitted from the laser component 324 passes through the transparent window 3214b and extends in an orthogonal direction perpendicular to the gas-inlet groove 3214.

In addition, the gas-guiding-component loading region 3215 of the base 321 is in fluid communication with the gas-inlet groove 3214. When the piezoelectric actuator 322 is enabled, the gas in the gas-inlet groove 3214 is inhaled by the piezoelectric actuator 322, so that the gas flows into the piezoelectric actuator 322, and is transported into the gas-outlet groove 3216 through the ventilation hole 3215a of the gas-guiding-component loading region 3215.

In the embodiment, the gas-injection plate 3221 is made by a flexible material and includes a suspension plate 3221a and a hollow aperture 3221b. The suspension plate 3221a is a sheet structure and is permitted to undergo a bending deformation. Preferably but not exclusively, the shape and the size of the suspension plate 3221a are accommodated in the inner edge of the gas-guiding-component loading region 3215, but not limited thereto. The hollow aperture 3221b passes through a center of the suspension plate 3221a, so as to allow the gas to flow therethrough. Preferably but not exclusively, in the embodiment, the shape of the suspension plate 3221a is selected from the group consisting of a square, a circle, an ellipse, a triangle and a polygon, but not limited thereto.

In the embodiment, the chamber frame 3222 is carried and stacked on the gas-injection plate 3221. In addition, the shape of the chamber frame 3222 is corresponding to the gas-injection plate 3221. The actuator element 3223 is carried and stacked on the chamber frame 3222. A resonance chamber 3226 is collaboratively defined by the actuator element 3223, the chamber frame 3222 and the suspension plate 3221a and is formed between the actuator element 3223, the chamber frame 3222 and the suspension plate 3221a. The insulation frame 3224 is carried and stacked on the actuator element 3223 and the appearance of the insulation frame 3224 is similar to that of the chamber frame 3222. The conductive frame 3225 is carried and stacked on the insulation frame 3224, and the appearance of the conductive frame 3225 is similar to that of the insulation frame 3224. In addition, the conductive frame 3225 includes a conducting pin 3225a and a conducting electrode 3225b. The conducting pin 3225a is extended outwardly from an outer edge of the conductive frame 3225, and the conducting electrode 3225b is extended inwardly from an inner edge of the conductive frame 3225. Moreover, the actuator element 3223 further includes a piezoelectric carrying plate 3223a, an adjusting resonance plate 3223b and a piezoelectric plate 3223c. The piezoelectric carrying plate 3223a is carried and stacked on the chamber frame 3222. The adjusting resonance plate 3223b is carried and stacked on the piezoelectric carrying plate 3223a. The piezoelectric plate 3223c is carried and stacked on the adjusting resonance plate 3223b. The adjusting resonance plate 3223b and the piezoelectric plate 3223c are accommodated in the insulation frame 3224. The conducting electrode 3225b of the conductive frame 3225 is electrically connected to the piezoelectric plate 3223c. In the embodiment, the piezoelectric carrying plate 3223a and the adjusting resonance plate 3223b are made by a conductive material. The piezoelectric carrying plate 3223a includes a piezoelectric pin 3223d. The piezoelectric pin 3223d and the conducting pin 3225a are electrically connected to a driving circuit (not shown) of the driving circuit board 323, so as to receive a driving signal, such as a driving frequency and a driving voltage. Through this structure, a circuit is formed by the piezoelectric pin 3223d, the piezoelectric carrying plate 3223a, the adjusting resonance plate 3223b, the piezoelectric plate 3223c, the conducting electrode 3225b, the conductive frame 3225 and the conducting pin 3225a for transmitting the driving signal. Moreover, the insulation frame 3224 is insulated between the conductive frame 3225 and the actuator element 3223, so as to avoid the occurrence of a short circuit. Thereby, the driving signal is transmitted to the piezoelectric plate 3223c. After receiving the driving signal such as the driving frequency and the driving voltage, the piezoelectric plate 3223c deforms due to the piezoelectric effect, and the piezoelectric carrying plate 3223a and the adjusting resonance plate 3223b are further driven to generate the bending deformation in the reciprocating manner.

Furthermore, in the embodiment, the adjusting resonance plate 3223b is located between the piezoelectric plate 3223c and the piezoelectric carrying plate 3223a and served as a cushion between the piezoelectric plate 3223c and the piezoelectric carrying plate 3223a. Thereby, the vibration frequency of the piezoelectric carrying plate 3223a is adjustable. Basically, the thickness of the adjusting resonance plate 3223b is greater than the thickness of the piezoelectric carrying plate 3223a, and the vibration frequency of the actuator element 3223 can be adjusted by adjusting the thickness of the adjusting resonance plate 3223b.

Please further refer to FIG. 7A, FIG. 7B, FIG. 8A, FIG. 8B and FIG. 9A. In the embodiment, the gas-injection plate 3221, the chamber frame 3222, the actuator element 3223, the insulation frame 3224 and the conductive frame 3225 are stacked and positioned in the gas-guiding-component loading region 3215 sequentially, so that the piezoelectric actuator 322 is supported and positioned in the gas-guiding-component loading region 3215. A plurality of clearances 3221c are defined between the suspension plate 3221a of the gas-injection plate 3221 and an inner edge of the gas-guiding-component loading region 3215 for gas flowing therethrough. In the embodiment, a flowing chamber 3227 is formed between the gas-injection plate 3221 and the bottom surface of the gas-guiding-component loading region 3215. The flowing chamber 3227 is in communication with the resonance chamber 3226 between the actuator element 3223, the chamber frame 3222 and the suspension plate 3221a through the hollow aperture 3221b of the gas-injection plate 3221. By controlling the vibration frequency of the gas in the resonance chamber 3226 to be close to the vibration frequency of the suspension plate 3221a, the Helmholtz resonance effect is generated between the resonance chamber 3226 and the suspension plate 3221a, so as to improve the efficiency of gas transportation. When the piezoelectric plate 3223c is moved away from the bottom surface of the gas-guiding-component loading region 3215, the suspension plate 3221a of the gas-injection plate 3221 is driven to move away from the bottom surface of the gas-guiding-component loading region 3215 by the piezoelectric plate 3223c. In that, the volume of the flowing chamber 3227 is expanded rapidly, the internal pressure of the flowing chamber 3227 is decreased to form a negative pressure, and the gas outside the piezoelectric actuator 322 is inhaled through the clearances 3221c and enters the resonance chamber 3226 through the hollow aperture 3221b. Consequently, the pressure in the resonance chamber 3226 is increased to generate a pressure gradient. When the suspension plate 3221a of the gas-injection plate 3221 is driven by the piezoelectric plate 3223c to move toward the bottom surface of the gas-guiding-component loading region 3215, the gas in the resonance chamber 3226 is discharged out rapidly through the hollow aperture 3221b, and the gas in the flowing chamber 3227 is compressed, thereby the converged gas is quickly and massively ejected out of the flowing chamber 3227 under the condition close to an ideal gas state of the Benulli's law, and transported to the ventilation hole 3215a of the gas-guiding-component loading region 3215.

By repeating the above operation steps shown in FIG. 9B and FIG. 9C, the piezoelectric plate 3223c is driven to generate the bending deformation in a reciprocating manner. According to the principle of inertia, since the gas pressure inside the resonance chamber 3226 is lower than the equilibrium gas pressure after the converged gas is ejected out, the gas is introduced into the resonance chamber 3226 again. Moreover, the vibration frequency of the gas in the resonance chamber 3226 is controlled to be close to the vibration frequency of the piezoelectric plate 3223c, so as to generate the Helmholtz resonance effect to achieve the gas transportation at high speed and in large quantities. The gas is inhaled through the gas-inlet 3214a on the outer cover 326, flows into the gas-inlet groove 3214 of the base 321 through the gas-inlet 3214a, and is transported to the position of the particulate sensor 325. The piezoelectric actuator 322 is 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 sensor 325. At this time, a projecting light beam emitted from the laser component 324 passes through the transparent window 3214b to irritate the suspended particles contained in the gas flowing above the particulate sensor 325 in the gas-inlet groove 3214. 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 sensor 325 for obtaining related information about the sizes and the concentration of the suspended particles contained in the gas. Moreover, the gas above the particulate sensor 325 is continuously driven and transported by the piezoelectric actuator 322, flows into the ventilation hole 3215a of the gas-guiding-component loading region 3215, and is transported to the gas-outlet groove 3216. At last, after the gas flows into the gas outlet groove 3216, the gas is continuously transported into the gas-outlet groove 3216 by the piezoelectric actuator 322, and thus the gas in the gas-outlet groove 3216 is pushed to discharge through the gas-outlet 3216a and the outlet opening 3261b.

The gas detector 3 of the present disclosure not only includes particulate sensor 325 for detecting the particulate matters in the gas, but also includes a gas sensor for detecting the gas characteristics of the introduced gas, for example, to determine whether the gas is formaldehyde, ammonia, carbon monoxide, carbon dioxide, oxygen, ozone, or the like. Therefore, in one or some embodiments, the gas detector 3 of the present disclosure further includes the gas sensor 327 positioned and disposed on the driving circuit board 323, electrically connected to the driving circuit board 323, and accommodated in the gas-outlet groove 3216, so as to detect the concentration or the characteristics of volatile organic compounds contained in the gas exported from the gas outlet path.
