Description

[Technical field]

[0001] The present invention relates to an air pollution control system for bathroom and toilet spaces, and more particularly to an indoor air pollution control system suitable for implementation in indoor bathroom and toilet areas. [Background technology]

[0002] Suspended particulates refer to solid particles or liquid droplets contained in gas. Because the particle size is very small, they can easily enter the human lungs through the nasal hairs in the nasal cavity, causing lung inflammation, asthma, cardiovascular disease, etc., and if other pollutants adhere to the suspended particulates, the harm to the respiratory system becomes even greater. In recent years, the problem of air pollution has become increasingly serious, and the concentration data of fine suspended particles (e.g., PM2.5) in particular is often too high, so monitoring the concentration of suspended particulates in gas has attracted attention. However, the flow of gas is unstable depending on the wind direction and volume, and most of the gas monitoring stations that currently detect suspended particulates are fixed-point type, so it is not possible to immediately check the concentration of suspended particulates in the surrounding area.

[0003] In addition, modern people are increasingly placing importance on the quality of the air around them, and gases such as carbon monoxide, carbon dioxide, volatile organic compounds (VOCs), PM2.5, nitrogen monoxide, sulfur monoxide, and even the fine particles contained in gases are all exposed to the environment, affecting human health and, in severe cases, even threatening life. Therefore, the quality of environmental gases has attracted the attention of many countries, and how to detect gas quality and avoid areas with poor gas quality or keep away from areas with poor gas quality is currently a hot topic.

[0004] As a method for checking the quality of gas, it is possible to use a gas sensor to detect the surrounding environmental gas. If the detection information can be provided in real time to warn people in the environment, so that the impact and injury of the gas hazard in the environment on human health can be prevented or avoided in real time, it is a very good application to use a gas sensor to detect the surrounding environment. In addition, the main research and development of the present invention is how to intelligently and quickly detect the source of indoor air pollution in the bathroom and toilet space area, maintain appropriate temperature and humidity, effectively remove indoor air pollution, and create a clean and safe air condition for breathing. Summary of the Invention [Problem to be solved by the invention]

[0005] The present invention is an air pollution prevention system for bathroom and toilet spaces. By disposing a plurality of gas detectors in various areas outdoors and indoors, the air pollution can be identified by the gas detectors, and air pollution information can be output and formed. The air pollution information is received and stored through a cloud computing service device, and a database of air pollution data is formed. When the air pollution data of the bathroom and toilet space exceeds a safe detection value, the cloud computing service device issues a control command to control the starting operation of the exhaust fan, thereby leading the air pollution in the bathroom and toilet space to be exhausted outside, and intelligently and selectively issues another control command, sends it to the air guide device of the filtering device to start its operation, and quickly guides the air pollution in the bathroom and toilet space to be filtered and removed by the filtering parts of the filtering device, and controls the air condition to zero the air pollution in the bathroom and toilet space. [Means for solving the problem]

[0006] In order to achieve the above object, the present invention provides an air pollution prevention system for bathroom and toilet spaces, which includes a plurality of gas detectors, at least one filtering device, at least one exhaust fan, and a cloud computing service device. The plurality of gas detectors are installed outdoors to detect air pollution and output / form outdoor air pollution information, and are installed in the bathroom and toilet spaces to detect air pollution and output / form indoor air pollution information.

The at least one exhaust fan is installed in the bathroom and toilet spaces to guide the air pollution in the bathroom and toilet spaces to be exhausted to the outside, and form a gas exchange in the bathroom and toilet spaces. The cloud computing service device receives and stores the outdoor air pollution information outside the room and the indoor air pollution information of the bathroom and toilet space, forms a database of air pollution data, and when the air pollution data of the bathroom and toilet space exceeds a safety detection value, intelligently and selectively issues a control command and sends it to the exhaust fan to start operating, guides the air pollution in the bathroom and toilet space to be exhausted outside, controls the gas exchange in the bathroom and toilet space to adjust the temperature and humidity, and performs artificial intelligence calculations to identify the location of the air pollution, intelligently and selectively issues another control command and sends it to the filtering device to start operating, quickly guides the air pollution in the bathroom and toilet space to be filtered and removed by the filtering device, and controls the air condition to reduce the air pollution in the bathroom and toilet space to zero.

[0008] The following description will provide detailed descriptions of the embodiments that illustrate the features and advantages of the present invention. It should be understood that the present invention can have various modifications in different aspects, all without departing from the scope of the present invention, and that the description and drawings are illustrative in nature, and are not intended to limit the present invention.

[0009] Referring to Figures 1A and 1B, the present invention is an air pollution prevention system for bathroom and toilet spaces, which includes a plurality of gas detectors 1, at least one filtering device 2, at least one exhaust fan 3, and a cloud computing service device 4.

[0010] The gas detectors 1 can be arranged in an outdoor area to detect air pollution and output / form outdoor air pollution information, and can be arranged inside the bathroom and toilet space A to detect air pollution and output / form indoor air pollution information. A gas detection module is installed inside the gas detector 1. As shown in FIG. 3C and FIG. 11, the gas detection module includes a control circuit board 11, a gas detection main body 12, a microprocessor 13, and a communication device 14. Note that the gas detector 1 may be in a form with an external power supply terminal, which can be started to operate and detect air pollution by directly inserting the external power supply terminal into a switch in the bathroom and toilet space A, as shown in FIG. 3A and FIG. 3B. Alternatively, as shown in FIG. 1A and FIG. 3C, the gas detector 1 may be in the form of a gas detection module without an external power supply terminal, which is directly incorporated into the device (filter 2, exhaust fan 3) and starts to operate and detects air pollution by connecting to a power source. That is, the gas detector 1 can be assembled into the filter 2 and connected to the driving operation of the filter 2, or can be assembled directly into the exhaust fan 3 and connected to the driving operation of the exhaust fan 3. The above air pollution refers to any one or combination of suspended particulate matter, carbon monoxide, carbon dioxide, ozone, sulfur dioxide, nitrogen dioxide, lead, total volatile organic compounds, formaldehyde, bacteria, fungi, and viruses.

[0011] As shown in FIG. 1A and FIG. 2A, the filtration device 2 is provided in the bathroom and toilet space A to filter air pollution in the bathroom and toilet space A. The filtration device 2 includes an air guide device 21 and a filtering component 22. The air guide device 21 is activated to guide air pollution in the bathroom and toilet space A to be filtered and removed by the filtering component 22. The gas detector 1 can be connected to the driving operation of the air guide device 21 of the filtration device 2, and when the gas detector 1 receives a control command, it can control the activation of the air guide device 21 and the rotation speed of the air guide device 21. The air intake path of the air guide device 21 is in the direction shown by the arrow in FIG. 2A, and the air guide device 21 may be installed in front of the filtering component 22 or may be installed behind the filtering component 22. As shown in FIG. 2B, the filtering component 22 is a filter screen. The filter screen can remove air pollution by physical methods of blocking and adsorption, and may be a high-efficiency filter screen 22a, which adsorbs chemical smog, bacteria, dust particles, and pollen contained in the air pollution, thereby achieving the effect of filtering and purifying the introduced air pollution. In addition, the above-mentioned filtering part 22 may be one that chemically removes air pollution by applying a decomposition layer 221 to the high-efficiency filter screen 22a. The decomposition layer 221 is activated carbon 221a, which removes organic and inorganic matter in air pollution and removes colored substances and odorous substances. The decomposition layer 221 is a chlorine dioxide cleaning factor 221b, which inhibits viruses, bacteria, fungi, influenza A virus, influenza B virus, enteric virus, and norovirus in air pollution, and the inhibition rate reaches 99% or more, contributing to reducing cross-infection of viruses. The decomposition layer 221 is a herbal protective layer 221c containing ginkgo and Japanese Rhus chinensis, which effectively resists allergies and destroys the surface proteins of influenza viruses (e.g., H1N1). The decomposition layer 221 is silver ions 221d, which inhibits viruses, bacteria, and fungi in the introduced air pollution. The decomposition layer 221 is zeolite 221e, which removes ammonia nitrogen, heavy metals, organic pollutants, E. coli, phenol, chloroform, and anionic surfactants. In some embodiments, the filtration component 22 can also remove air pollution chemically in combination with light irradiation 222.The light irradiation 222 is a photocatalyst unit including a photocatalyst 222a and an ultraviolet lamp 222b. When the photocatalyst 222a is irradiated by the ultraviolet lamp 222b, it converts light energy into electrical energy, and decomposes harmful substances in air pollution to disinfect and sterilize, thereby achieving the effect of filtering and purifying. The light irradiation 222 is an optical plasma unit including an optical nanotube 222c. By irradiating the introduced air pollution with the optical nanotube 222c, the oxygen molecules and water molecules in the air pollution are decomposed into optical plasma having high oxidizing properties, and an ion airflow having destroyed organic molecules is formed, and the gas molecules such as volatile formaldehyde, toluene, and volatile organic gases (VOCs) contained in the air pollution are decomposed into water and carbon dioxide, thereby achieving the effect of filtering and purifying. In some embodiments, the filtering component 22 can also be combined with the decomposition unit 223 to chemically remove air pollution. The decomposition unit 223 is a negative ion unit 223a, which adheres positively charged fine particles contained in the introduced air pollution to a negatively charged dust collecting plate to achieve the effect of filtering and purifying the introduced air pollution. The decomposition unit 223 is a plasma ion unit 223b, which ionizes oxygen molecules and water molecules contained in the air pollution with plasma ions to turn them into positive ions (H. + ) and anions (O 2- ) and the substances with water molecules attached around the ions attach to the surface of viruses and bacteria, where they are converted into powerful oxidizing active oxygen (hydroxyl group, OH group) through a chemical reaction, which steals hydrogen from the surface proteins of the viruses and bacteria and oxidizes and decomposes them, thereby achieving the effect of filtering and purifying the introduced air pollution.

[0012] As shown in FIG. 1A, the exhaust fan 3 is installed in the bathroom and toilet space A, and guides air pollution in the bathroom and toilet space A and exhausts it to the outside, thereby forming a gas exchange in the bathroom and toilet space A. The gas detector 1 is directly incorporated in the exhaust fan 3 in the form of a gas detection module, and is connected to the driving operation of the exhaust fan 3. Upon receiving a control command, the gas detector 1 can control the start-up of the exhaust fan 3 and the rotation speed of the exhaust fan 3.

[0013] As shown in Fig. 1A, the cloud computing service device 4 receives and stores outdoor air pollution information and indoor air pollution information of the bathroom and toilet space A, forming a database of air pollution data. When the air pollution data of the bathroom and toilet space A exceeds the safety detection value, it intelligently and selectively issues a control command and sends it to the exhaust fan 3 to start operating, thereby guiding the air pollution in the bathroom and toilet space A to be exhausted to the outside, controls the gas exchange in the bathroom and toilet space A to adjust the temperature and humidity, and performs an artificial intelligence calculation to identify the location of the air pollution, intelligently and selectively issues another control command and sends it to the filtration device 2 to start operating, guiding the air pollution in the bathroom and toilet space A to be quickly filtered and removed by the filtration device 2, and controls the air condition of the bathroom and toilet space A to be zero.

[0014] Refer to FIG. 12. The cloud computing service device 4 includes a wireless network cloud computing service module 41, a cloud control service unit 42, a device management unit 43, and an application unit 44. The wireless network cloud computing service module 41 receives the air pollution communication information of the outdoor and bathroom and toilet space A, and sends a control command. The wireless network cloud computing service module 41 receives the air pollution information of the outdoor and bathroom and toilet space A, sends the air pollution information and the air pollution communication information to the cloud control service unit 42 for storage, forms a database of air pollution data, performs artificial intelligence calculations, and compares the database of air pollution data to identify the location of air pollution, issues a control command, and sends it to the wireless network cloud computing service module 41, and sends it to the filtration device 2 and the exhaust fan 3 via the wireless network cloud computing service module 41 to control the start-up operation. The device management unit 43 can receive the communication information of the filtration device 2 and the exhaust fan 3 via the wireless network cloud computing service module 41 for user login management and device binding management, and provide device management information to the application unit 44 for system control management. The application unit 44 displays and notifies the user of the air pollution information obtained by the cloud control service unit 42, allowing the user to grasp the air pollution removal status in real time via his / her mobile phone or communication device, and to control the operation of the air pollution prevention system for the bathroom and toilet space via the application unit 44 of his / her mobile phone or communication device.

[0015] As can be seen from the above description, the present invention is a system for preventing air pollution in bathroom and toilet spaces. A plurality of gas detectors 1 in the bathroom and toilet space A and outside the room detect indoor and outdoor air pollution, output and form indoor air pollution information and outdoor air pollution information respectively, and a cloud computing service device 4 receives and stores the air pollution information to form an air pollution data database. When the air pollution information in the bathroom and toilet space A is higher than the outdoor air pollution information, the cloud computing service device 4 issues a control command to control the starting operation of the exhaust fan 3 to guide the air pollution in the bathroom and toilet space A to be exhausted to the outside, and intelligently and selectively issues another control command to the air guide device 21 of the filtering device 2 to start its operation, and quickly guides the air pollution in the bathroom and toilet space A to be filtered and removed by the filtering part 22 of the filtering device 2, and controls the air condition to zero the air pollution in the bathroom and toilet space A.

[0016] In addition, if the air pollution data of the bathroom and toilet space A exceeds a safe detection value, for example, if the detection values ​​of the air pollution data CO2, VOC, PM2.5, and temperature and humidity exceed the set safe detection values ​​of the air pollution data, the cloud computing service device 4 issues a control command and sends the exhaust fan 3 to start operating, thereby controlling the gas exchange in the bathroom and toilet space A and adjusting the temperature and humidity in the bathroom and toilet space A.

[0017] The above safety detection values ​​include suspended particulate matter 2.5 (PM 2.5 ) at a concentration of 10 μg / m 3 carbon dioxide (CO2) concentration is less than 1000 ppm, total volatile organic compounds (TVOC) concentration is less than 0.56 ppm, formaldehyde (HCHO) concentration is less than 0.08 ppm, and bacterial count is 1500 CFU / m 3 Less than 1000 CFU / m 3less than 0.075 ppm, sulfur dioxide concentration less than 0.1 ppm, carbon monoxide concentration less than 9 ppm, ozone concentration less than 0.06 ppm, lead concentration less than 0.15 μg / m 3 This includes temperature and humidity (RH%) being greater than 30 and less than 70.

[0018] In some specific embodiments, as shown in Figures 1A and 1B, multiple gas detectors 1 are arranged in the bathroom and toilet space A. Take the gas detector 1 installed in the bathroom and toilet space A to detect airborne particulate matter PM2.5 as an example. When a user activates the air pollution prevention system in the bathroom and toilet space A before 7:40, the value of the airborne particulate matter PM2.5 in the bathroom and toilet space A is close to the value of the outdoor airborne particulate matter PM2.5. When the air pollution prevention system for bathroom and toilet space A is started at 7:40, the gas detector 1 in bathroom and toilet space A detects suspended particulate PM2.5, and at the same time, the cloud computing service device 4 receives and compares at least two or more pieces of air pollution data detected by the multiple gas detectors 1 in bathroom and toilet space A, performs intelligent calculations to determine and identify the location of air pollution in bathroom and toilet space A, intelligently and selectively issues control commands and transmits them to the air guide device 21 to control the startup operation of the air guide device 21 of the filtering device 2, thereby generating a directional airflow and quickly directing the air pollution to the filtering part 22 for filtering and removal. At 7:44, it can be seen that the air pollution value of the entire bathroom and toilet space A drops sharply, and the effect of reducing air pollution to zero continues thereafter.

[0019] In order to understand the embodiment of the air pollution prevention system for bathroom and toilet spaces of the present invention, the structure of the gas detector 1 of the present invention will be described in detail below.

[0020] A gas detection module is provided inside gas detector 1, and the gas detection module includes a control circuit board 11, a gas detection main body 12, a microprocessor 13, and a communication device 14. Gas detection main body 12, microprocessor 13, and communication device 14 are packaged and integrally formed in control circuit board 11, and are electrically connected to each other. Microprocessor 13 and communication device 14 are installed on control circuit board 11, and microprocessor 13 controls a drive signal for gas detection main body 12 to start a detection operation, whereby gas detection main body 12 detects air pollution and outputs detection information, and microprocessor 13 receives the detection information, processes and outputs it, provides it to communication device 14 for external communication, and transmits it to cloud computing service device 4.

[0021] Please refer to Figs. 4A to 9A. The gas detection main body 12 includes a base 121, a piezoelectric actuator 122, a drive circuit board 123, a laser component 124, a particulate sensor 125, and an outer lid 126. The base 121 has a first surface 1211, a second surface 1212, a laser installation area 1213, an intake groove 1214, an air-conducting component mounting area 1215, and an exhaust groove 1216. The first surface 1211 and the second surface 1212 are two surfaces that are installed opposite each other. The laser installation area 1213 is formed by hollowing out from the first surface 1211 toward the second surface 1212. The outer lid 126 covers the base 121, and has a side plate 1261 that has an intake frame opening 1261a and an exhaust frame opening 1261b. The intake groove 1214 is recessed from the second surface 1212 and is adjacent to the laser installation area 1213. The intake groove 1214 is provided with an intake vent 1214a that communicates with the outside of the base 121 and corresponds to the intake frame port 1261a of the outer lid 126, and both side walls of the intake groove 1214 are penetrated by light transmission windows 1214b and communicates with the laser installation area 1213. Thus, the first surface 1211 of the base 121 is covered by the outer lid 126, and the second surface 1212 is covered by the drive circuit board 123, thereby defining an intake path by the intake groove 1214.

[0022] The air-conducting component mounting area 1215 is recessed from the second surface 1212, communicates with the intake groove 1214, has a vent hole 1215a penetrating the bottom surface, and has positioning protrusions 1215b at each of the four corners of the air-conducting component mounting area 1215. The exhaust groove 1216 is provided with an exhaust vent 1216a that is installed corresponding to the exhaust frame opening 1261b of the outer lid 126. The exhaust groove 1216 includes a first section 1216b recessed from the vertical projection area of ​​the first surface 1211 onto the air-conducting component mounting area 1215, and a second section 1216c hollowed out from the first surface 1211 toward the second surface 1212 in an area extending from the vertical projection area of ​​the air-conducting component mounting area 1215, and the first section 1216b is connected to the second section 1216c to form a step. A first section 1216b of the exhaust groove 1216 communicates with the ventilation hole 1215a of the air-conducting component mounting area 1215, and a second section 1216c of the exhaust groove 1216 communicates with the exhaust vent 1216a. Thus, when the first surface 1211 of the base 121 is covered with the outer lid 126 and the second surface 1212 is covered with the drive circuit board 123, the exhaust groove 1216 and the drive circuit board 123 together define an exhaust path.

[0023] The laser component 124 and the particle sensor 125 are both installed on the drive circuit board 123 and located in the base 121, and the drive circuit board 123 is intentionally omitted in order to clearly explain the positions of the laser component 124, the particle sensor 125, and the base 121. The laser component 124 is accommodated in the laser installation area 1213 of the base 121, and the particle sensor 125 is accommodated in the intake groove 1214 of the base 121 and aligned with the laser component 124. In addition, the laser component 124 corresponds to the light transmission window 1214b through which the laser light emitted by the laser component 124 passes, thereby irradiating the laser light to the intake groove 1214. The beam path emitted by the laser component 124 passes through the light transmission window 1214b and is perpendicular to the intake groove 1214. The beam emitted by the laser component 124 passes through the light-transmitting window 1214b and enters the intake groove 1214, irradiating the gas in the intake groove 1214. When the beam comes into contact with the gas, it scatters to generate a projection spot, and the particle sensor 125 located at the orthogonal direction receives the scattered projection spot and performs calculations to obtain gas detection data.

[0024] The piezoelectric actuator 122 is accommodated in a square air-conducting component mounting area 1215 of the base 121. The air-conducting component mounting area 1215 is connected to an intake groove 1214. When the piezoelectric actuator 122 is activated, the gas in the intake groove 1214 is sucked into the piezoelectric actuator 122, and the gas passes through a vent hole 1215a of the air-conducting component mounting area 1215 and enters the exhaust groove 1216. The driving circuit board 123 covers the second surface 1212 of the base 121. The laser component 124 is installed and electrically connected to the driving circuit board 123. The particulate sensor 125 is also installed and electrically connected to the driving circuit board 123. When the outer cover 126 covers the base 121, the intake frame port 1261a corresponds to the intake vent port 1214a of the base 121, and the exhaust frame port 1261b corresponds to the exhaust vent port 1216a of the base 121.

[0025] The piezoelectric actuator 122 includes a gas orifice plate 1221, a chamber housing 1222, an actuator 1223, an insulating housing 1224, and a conductive housing 1225. The gas orifice plate 1221 is made of a flexible material and has a suspension plate 1221a and a hollow hole 1221b, the suspension plate 1221a is a sheet-like structure that vibrates in bending, and its shape and dimensions correspond to the inner edge of the air-conducting component mounting area 1215, and the hollow hole 1221b penetrates the center of the suspension plate 1221a to allow gas to flow through. In a preferred embodiment of the present invention, the shape of the suspension plate 1221a may be any of a square, a circle, an ellipse, a triangle, and a polygon.

[0026] The chamber housing 1222 is stacked on the gas orifice plate 1221, and its appearance corresponds to the gas orifice plate 1221. The actuator 1223 is stacked on the chamber housing 1222, and defines a resonant chamber 1226 between the chamber housing 1222 and the suspension plate 1221a. The insulating housing 1224 is stacked on the actuator 1223, and its appearance is similar to the chamber housing 1222. The conductive housing 1225 is stacked on the insulating housing 1224, and its appearance is similar to the insulating housing 1224. The conductive housing 1225 has a conductive pin 1225a and a conductive electrode 1225b, where the conductive pin 1225a extends outward from the outer edge of the conductive housing 1225, and the conductive electrode 1225b extends inward from the inner edge of the conductive housing 1225. The actuator 1223 further includes a piezoelectric carrier plate 1223a, a resonance adjustment plate 1223b, and a piezoelectric plate 1223c. The piezoelectric carrier plate 1223a is stacked on the chamber housing 1222. The resonance adjustment plate 1223b is stacked on the piezoelectric carrier plate 1223a. The piezoelectric plate 1223c is stacked on the resonance adjustment plate 1223b. The resonance adjustment plate 1223b and the piezoelectric plate 1223c are housed in an insulating housing 1224. The conductive electrode 1225b of the conductive housing 1225 is electrically connected to the piezoelectric plate 1223c. In a preferred embodiment of the present invention, both the piezoelectric carrier plate 1223a and the resonance adjustment plate 1223b are made of conductive materials. The piezoelectric carrier plate 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). The driving signal can form a loop through the piezoelectric pin 1223d, the piezoelectric carrier plate 1223a, the resonance adjustment plate 1223b, the piezoelectric plate 1223c, the conductive electrode 1225b, the conductive housing 1225, and the conductive pin 1225a, and the insulating housing 1224 can cut off the conductive housing 1225 and the actuator 1223 to prevent a short circuit phenomenon, and the driving signal can be transmitted to the piezoelectric plate 1223c. After receiving the driving signal, the piezoelectric plate 1223c is deformed by the piezoelectric effect, and further drives the piezoelectric carrier plate 1223a and the resonance adjustment plate 1223b to generate a reciprocating bending vibration.

[0027] To explain further, resonance adjustment plate 1223b is located between piezoelectric plate 1223c and piezoelectric carrier plate 1223a as a buffer between them, and can adjust the vibration frequency of piezoelectric carrier plate 1223a. Basically, the thickness of resonance adjustment plate 1223b is greater than that of piezoelectric carrier plate 1223a, and the vibration frequency of actuator 1223 can be adjusted by changing the thickness of resonance adjustment plate 1223b.

[0028] Please refer to Figures 7A, 7B, 8A, 8B, and 9A. The gas orifice plate 1221, the chamber housing 1222, the actuator 1223, the insulating housing 1224, and the conductive housing 1225 are stacked and positioned in order in the air-conducting component mounting area 1215, so that the piezoelectric actuator 122 is positioned in the air-conducting component mounting area 1215, and the piezoelectric actuator 122 defines a gap 1221c for gas flow between the suspension plate 1221a and the inner edge of the air-conducting component mounting area 1215. An airflow chamber 1227 is formed between the gas orifice plate 1221 and the air-conducting component mounting area 1215. The airflow chamber 1227 is connected to a resonant chamber 1226 between the actuator 1223, the chamber housing 1222, and the suspension plate 1221a via a hollow hole 1221b in the gas orifice plate 1221. By making the vibration frequency of the gas in the resonant chamber 1226 the same as the vibration frequency of the suspension plate 1221a, the resonant chamber 1226 and the suspension plate 1221a generate a Helmholtz resonance effect, thereby increasing the gas transport efficiency. When the piezoelectric plate 1223c moves away from the bottom surface of the air-conducting component mounting area 1215, the piezoelectric plate 1223c moves the suspension plate 1221a of the gas orifice plate 1221 away from the bottom surface of the air-conducting component mounting area 1215, causing the volume of the airflow chamber 1227 to expand suddenly, the internal pressure to decrease and generate negative pressure, and gas outside the piezoelectric actuator 122 is sucked in and flows in through the gap 1221c, passes through the hollow hole 1221b, and enters the resonating chamber 1226, increasing the air pressure in the resonating chamber 1226 and generating a pressure gradient. When the piezoelectric plate 1223c moves the suspension plate 1221a of the gas orifice plate 1221 to the bottom surface of the air-conducting component mounting area 1215, the gas in the resonating chamber 1226 quickly flows out through the hollow hole 1221b, squeezing out the gas in the airflow chamber 1227, and the merged gas is quickly and in large quantities ejected in an ideal gas state close to Bernoulli's theorem, and introduced into the ventilation hole 1215a of the air-conducting component mounting area 1215.

[0029] 9B and 9C, the piezoelectric plate 1223c vibrates back and forth, and according to the principle of inertia, when the internal air pressure of the resonating chamber 1226 after exhaust becomes lower than the equilibrium air pressure, the gas is guided back into the resonating chamber 1226. In this way, the vibration frequency of the gas in the resonating chamber 1226 is controlled to be the same as the vibration frequency of the piezoelectric plate 1223c, thereby generating the Helmholtz resonance effect and realizing high-speed and large-volume gas transport. All the gas enters from the intake frame port 1261a of the outer cover 126, passes through the intake vent 1214a, enters the intake groove 1214 of the base 121, and flows to the position of the particle sensor 125. In addition, the gas in the intake path is absorbed by the continuous driving of the piezoelectric actuator 122, so that the external gas is rapidly introduced and stably flows, and passes above the particle sensor 125. At this time, the beam emitted by the laser component 124 passes through the light transmission window 1214b and enters the intake groove 1214, and the intake groove 1214 passes above the particle sensor 125. When the beam of the particle sensor 125 is irradiated on the suspended particles in the gas, a scattering phenomenon and a projection spot are generated, and the particle sensor 125 receives the scattered projection spot and performs calculations to obtain related information such as the particle diameter and concentration of the suspended particles contained in the gas. The gas above the particle sensor 125 is also introduced into the ventilation hole 1215a of the air-conducting component mounting area 1215 by the continuous driving of the piezoelectric actuator 122, and enters the exhaust groove 1216. Finally, after the gas enters the exhaust groove 1216, the piezoelectric actuator 122 continues to transport the gas to the exhaust groove 1216, so that the gas in the exhaust groove 1216 is pushed out and discharged to the outside through the exhaust vent 1216a and the exhaust frame port 1261b.

[0030] The gas detector 1 of the present invention can not only detect suspended particles in the gas, but also detect the characteristics of the introduced gas, such as formaldehyde, ammonia, carbon monoxide, carbon dioxide, oxygen gas, and ozone. Therefore, the gas detector 1 of the present invention further includes a gas sensor 127, which is positioned and installed on the driving circuit board 123, electrically connected to the driving circuit board 123, and housed in the exhaust groove 1216 to detect the characteristics of the introduced gas. The gas sensor 127 is a volatile organic compound sensor that detects gas information of carbon dioxide or total volatile organic compounds. The gas sensor 127 may be a formaldehyde sensor that detects gas information of formaldehyde. The gas sensor 127 may be a bacteria sensor that detects bacteria information or fungus information. The gas sensor 127 may be a virus sensor that detects gas information of viruses. The gas sensor 127 may be a temperature and humidity sensor that detects temperature and humidity information of the gas.

[0031] As described above, the present invention provides an air pollution prevention system for bathrooms and toilet spaces to solve the problem that indoor air pollution occurs and moves from time to time and is difficult to grasp. In the present invention, a plurality of gas detectors are arranged in various areas outdoors and indoors, and the air pollution is identified by the gas detectors, and air pollution information is output and formed, and the air pollution information is received and stored via a cloud computing service device, forming an air pollution data database. When the air pollution data of the bathroom and toilet space exceeds a safe detection value, the cloud computing service device issues a control command to control the starting operation of the exhaust fan to guide the air pollution in the bathroom and toilet space to be exhausted to the outside, and intelligently and selectively issues another control command to send it to the air guide device of the filtering device to start its operation, and quickly guides the air pollution in the bathroom and toilet space to be filtered and removed by the filtering parts of the filtering device, and controls the air condition to zero the air pollution in the bathroom and toilet space, which has a very high industrial applicability.
