Description

Technical Field

[0001] The present invention relates to an air pollution prevention and control system for bathroom spaces, and in particular to an indoor air pollution prevention and control system suitable for indoor bathrooms and toilets. Background Art

[0002] Suspended particulate matter refers to solid particles or droplets contained in the gas. Due to its very fine particle size, it is easy for it to enter the human lungs through the nasal hair in the nasal cavity, thus causing lung inflammation, asthma or cardiovascular disease. If other pollutants are attached to the suspended particulate matter, it will aggravate the harm to the respiratory system. In recent years, the problem of gas pollution has become increasingly serious, especially the concentration data of fine suspended particulate matter (such as PM2.5) is often too high. The monitoring of gas suspended particulate concentration has gradually received attention. However, since the gas will flow unstably with the wind direction and wind volume, and the gas quality monitoring stations that currently detect suspended particulates are mostly fixed points, it is impossible to confirm the concentration of suspended particulates in the surrounding area.

[0003] In addition, modern people are paying more and more attention to the quality of the gases around them. For example, gases such as carbon monoxide, carbon dioxide, volatile organic compounds (VOC), PM2.5, nitric oxide, sulfur oxide, and even particles contained in the gases will affect human health when exposed in the environment, and even endanger life in serious cases. Therefore, the quality of environmental gases has attracted the attention of various countries. How to detect gas quality to avoid and stay away from areas with poor gas quality is a current issue of concern.

[0004] How to confirm the quality of gas? It is feasible to use a gas sensor to detect the surrounding gas. If it can provide detection information in real time to warn people in the environment, so that they can take immediate precautions or escape, and avoid the harm of gas in the environment and the impact and harm to human health, using a gas sensor to detect the surrounding environment can be said to be a very good application. In addition, how to intelligently and quickly detect indoor air pollution sources in the bathroom space and maintain appropriate temperature and humidity, effectively remove indoor air pollution to form a clean and safe gas state, is the main topic developed by the present invention. Summary of the invention

[0005] The present invention is an air pollution prevention and control system for bathroom spaces. By deploying multiple gas detectors in various outdoor and indoor fields, the gas detectors can determine the air pollution and output air pollution information, which is then received and stored by a cloud computing service device to form a database of air pollution data. When the air pollution data in the bathroom space exceeds the safety detection value, the cloud computing service device sends a control instruction to control the exhaust fan to start the operation, and the air pollution in the bathroom space is drained and discharged outdoors. At the same time, it intelligently selects to send another control instruction to the fan start operation of the filter device, so that the air pollution in the bathroom space can be quickly drained through the filter element of the filter device for filtration and removal, thereby controlling the gas state of the air pollution in the bathroom space to approach zero.

[0006] To achieve the above-mentioned purpose, the present invention provides an air pollution prevention and control system for bathroom spaces, comprising: a plurality of gas detectors, each of which is respectively arranged outdoors to detect air pollution and output to form outdoor air pollution information, and is arranged in the bathroom space to detect air pollution and output to form indoor air pollution information; at least one filtering device, arranged in the bathroom space, to filter the air pollution in the bathroom space; at least one exhaust fan, arranged in the bathroom space, to drain the air pollution in the bathroom space to the outdoors, to form gas exchange in the bathroom space; a cloud computing service device, to receive the outdoor air pollution information and the bathroom space The indoor air pollution information is stored to form an air pollution data database. When the air pollution data of the bathroom space exceeds the safety detection value, it intelligently selects to issue a control instruction to the exhaust fan to start the operation, and drains the air pollution of the bathroom space to the outdoors, and controls the gas exchange of the bathroom space to adjust the temperature and humidity, and simultaneously implements artificial intelligence calculations to determine the location of the air pollution, and intelligently selects to issue another control instruction to the filter device to start the operation, so that the air pollution in the bathroom space can be quickly drained and filtered and removed through the filter device, and the gas state of the air pollution in the bathroom space can be controlled to approach zero.

[0033] Embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various variations in different aspects without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially used for illustration purposes rather than for limiting the present invention.

[0034] See also Figure 1A and Figure 1B As shown, the present invention is an air pollution prevention and control system for bathroom space, comprising: a plurality of gas detectors 1, at least one filter device 2, at least one exhaust fan 3 and a cloud computing service device 4.

[0035] The above-mentioned multiple gas detectors 1 can be deployed in outdoor areas to detect air pollution and output to form outdoor air pollution information, and can be deployed inside bathroom space A to detect air pollution and output to form indoor air pollution information. The above-mentioned gas detector 1 is internally provided with a gas detection module, and the gas detector 1 internally includes a gas detection module, such as Figure 3C Shown and Fig.11 As shown, the gas detection module includes: a control circuit board 11, a gas detection body 12, a microprocessor 13 and a communicator 14. It is worth noting that the gas detector 1 can be a Figure 3A and Figure 3B The configuration shown contains an external power terminal, which can be directly used to plug the external power terminal into the switch in the bathroom space A to start the air pollution detection operation. Figure 1A , Figure 3C The gas detection module shown does not contain an external power terminal, and is directly constructed on the device (filter device 2, exhaust fan 3) to connect the power supply to start the operation to detect air pollution. In other words, the gas detector 1 can be embedded in the filter device 2 and connected to the drive operation of the filter device 2, or directly embedded in the exhaust fan 3 and connected to the drive operation of the exhaust fan 3. It is worth noting that the above-mentioned air pollution refers to one or a combination of suspended particulate matter, carbon monoxide, carbon dioxide, ozone, sulfur dioxide, nitrogen dioxide, lead, total volatile organic compounds, formaldehyde, bacteria, fungi, and viruses.

[0036] like Figure 1A , Figure 2A As shown, the above-mentioned filter device 2 is arranged in the bathroom space A to filter the air pollution in the bathroom space A, and the filter device 2 includes a fan 21 and a filter element 22. The fan 21 starts to drain the air pollution in the bathroom space A to be filtered and removed through the filter element 22. It is worth noting that the gas detector 1 can be connected to the driving operation of the fan 21 of the filter device 2. When the gas detector 1 receives the control command, it can control the start of the fan 21 and control the speed of the fan 21. The air intake path of the above-mentioned fan 21 is Figure 2A In the direction indicated by the arrow, the fan 21 can be arranged in front of the filter element 22, or the fan 21 can be arranged in the rear of the filter element 22. Figure 2BAs shown, the filter element 22 is a filter. The filter removes air pollution by blocking and adsorbing physical methods, and is a high-efficiency filter 22a, which absorbs chemical smoke, bacteria, dust particles and pollen contained in the air pollution, so as to introduce the air pollution and achieve the effect of filtering and purification; it is worth noting that the filter element 22 can also be a high-efficiency filter 22a combined with a chemical method of coating a decomposition layer 221 to remove air pollution. The decomposition layer 221 is an activated carbon 221a, which removes organic and inorganic substances in the air pollution, and removes colored and odorous substances. The decomposition layer 221 is a chlorine dioxide cleaning factor 221b, which inhibits viruses, bacteria in the air pollution. The inhibition rate of bacteria, fungi, influenza A virus, influenza B virus, enterovirus, and norovirus is more than 99%, which helps to reduce viral cross-infection. The decomposition layer 221 is a herbal protective layer 221c of ginkgo and Japanese rhus chinensis, which is effective in anti-allergy and destroying the surface protein of influenza virus (for example: H1N1). The decomposition layer 221 is a silver ion 221d, which inhibits the introduction of viruses, bacteria, and fungi into the air pollution. The decomposition layer 221 is a zeolite 221e, which removes ammonia nitrogen, heavy metals, organic pollutants, Escherichia coli, phenol, chloroform and anionic surfactants. In some embodiments, the filter element 22 can also be used in combination with a light irradiation 222 to remove air pollution in a chemical manner. The light irradiation 222 is a photocatalyst unit of a photocatalyst 222a and an ultraviolet lamp 222b. When the photocatalyst 222a is irradiated by the ultraviolet lamp 222b, the light energy is converted into electrical energy to decompose harmful substances in the air pollution and sterilize the air pollution to achieve the effect of filtering and purification. The light irradiation 222 is a photoplasma unit of a nano-light tube 222c. The air pollution introduced by the nano-light tube 222c is irradiated to decompose oxygen molecules and water molecules in the air pollution into highly oxidizing photoplasmas, forming an ion flow that can destroy organic molecules, and volatile formaldehyde, toluene, and volatile organic gases (Volatile Organic Compounds, VOC) and other gas molecules are decomposed into water and carbon dioxide to achieve the effect of filtering and purifying; and in some embodiments, the filter element 22 can also be used with a decomposition unit 223 to remove air pollution in a chemical manner, and the decomposition unit 223 is a negative ion unit 223a, so that the particles contained in the introduced air pollution with positive charge are attached to the negatively charged particles, thereby achieving the effect of filtering and purifying the introduced air pollution; and the decomposition unit 223 is a plasma ion unit 223b, through which the oxygen molecules and water molecules contained in the air pollution are ionized to generate cations (H + ) and anions (O 2- ), and after the substances with water molecules attached to the ions attach to the surface of viruses and bacteria, they will be converted into highly oxidizing active oxygen (hydroxyl, OH group) under the action of chemical reactions, thereby taking away the hydrogen of the proteins on the surface of viruses and bacteria, oxidizing and decomposing them, so as to achieve the effect of filtering and purifying the introduced air pollution.

[0037] like Figure 1A As shown, the exhaust fan 3 is installed in the bathroom space A to drain the air and waste in the bathroom space A to the outside, thus forming a gas exchange in the bathroom space A. It is worth noting that the gas detector 1 is directly embedded 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. When the gas detector 1 receives a control command, it can control the exhaust fan 3 to start and control the speed of the exhaust fan 3.

[0038] like Figure 1A As shown, the cloud computing service device 4 receives outdoor air pollution information and indoor air pollution information of bathroom space A, and stores to form a database of air pollution data. When the air pollution data of bathroom space A exceeds the safety detection value, it intelligently selects to issue a control instruction to transmit to the exhaust fan 3 to start the operation, and drains the air pollution of bathroom space A to the outdoors, and controls the gas exchange of bathroom space A to adjust the temperature and humidity, and simultaneously implements artificial intelligence calculations to determine the location of the air pollution, and intelligently selects to issue another control instruction to transmit to the filter device 2 to start the operation, so that the air pollution in the bathroom space A can be quickly drained through the filter device 2 for filtration and removal, and the gas state of the air pollution in the bathroom space A can be controlled to approach zero.

[0039] Please see again Fig.12 As shown, 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, wherein the wireless network cloud computing service module 41 receives the air pollution communication information of the outdoor and bathroom 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 space A, and transmits the communication information to the cloud control service unit 42 to store and form a database of air pollution data, and implements artificial intelligence calculations and determines the location of the air pollution through the database comparison of the air pollution data, and sends a control command to the wireless network cloud computing service module 41. The information is then transmitted to the filter device 2 and the exhaust fan 3 through the wireless network cloud computing service module 41 to control the startup operation. The device management unit 43 receives the communication information of the filter device 2 and the exhaust fan 3 through the wireless network cloud computing service module 41 for user login management and device binding management, and can provide the device management information to the application unit 44 for system control management. The application unit 44 also displays and notifies the air pollution information obtained through the cloud control service unit 42, allowing the user to understand the real-time status of air pollution removal through a mobile phone or communication device, and the user can control the operation of the air pollution prevention and control system of the bathroom space through the application unit 44 of the mobile phone or communication device.

[0040] From the above description, it can be seen that the air pollution prevention and control system of the bathroom space of the present invention determines and detects indoor and outdoor air pollution by multiple gas detectors 1 in the bathroom space A and outdoors, and outputs them respectively to form an indoor air pollution information and an outdoor air pollution information, which are received and stored by the cloud computing service device 4 to form an air pollution data database. If the air pollution information of the bathroom space A is higher than the outdoor air pollution information, the cloud computing service device 4 sends a control instruction to control the exhaust fan 3 to start the operation, and the air pollution in the bathroom space A is drained and discharged outdoors. At the same time, it intelligently selects to send another control instruction to the fan 21 of the filter device 2 to start the operation, so that the air pollution in the bathroom space A can be quickly drained through the filter element 22 of the filter device 2 for filtration and removal, and the gas state of the air pollution in the bathroom space A is controlled to be close to zero.

[0041] Moreover, when the air pollution data of the bathroom space A exceeds the safety detection value, the air pollution data is the detection value of CO2, VOC, PM2.5 and temperature and humidity, and exceeds the set safety detection value of the air pollution data, the cloud computing service device 4 sends a control instruction to the exhaust fan 3 to start the operation, thereby controlling the gas exchange in the bathroom space A and adjusting the temperature and humidity in the bathroom space A.

[0042] It is worth noting that the above safety detection value includes suspended particulate matter 2.5 (PM 2.5 ) concentration is less than 10 μg / m 3 , carbon dioxide (CO2) concentration less than 1000ppm, total volatile organic compound (TVOC) concentration less than 0.56ppm, formaldehyde (HCHO) concentration less than 0.08ppm, bacterial count less than 1500CFU / m 3 、Fungal count less than 1000 CFU / m 3 , sulfur dioxide concentration less than 0.075ppm, nitrogen dioxide concentration less than 0.1ppm, carbon monoxide concentration less than 9ppm, ozone concentration less than 0.06ppm, lead concentration less than 0.15μg / m 3 , temperature and humidity RH% is between less than 70 and greater than 30.

[0043] Again, in some specific embodiments, such as Figure 1AAs shown, multiple gas detectors 1 are installed in the bathroom space A. Take the gas detector 1 installed in the bathroom space A to detect suspended particulate matter PM2.5 as an example. When the user starts the air pollution control system of the bathroom space A before 7:40, the suspended particulate matter PM2.5 value of the bathroom space A is similar to the outdoor suspended particulate matter PM2.5 value. When the air pollution control system of the bathroom space A is started at 7:40, when the gas detector 1 of the bathroom space A detects the suspended particulate matter PM2.5, the cloud computing service device 4B receives and compares at least 2 or more air pollution data detected by the multiple gas detectors 1 of the bathroom space A, and intelligently calculates and judges to find the location of the air pollution in the bathroom space A, and intelligently chooses to send a control instruction to the fan 21, prompting the fan 21 of the filter device 2 to start the operation, so as to generate a directional airflow and quickly guide the air pollution to the filter element 22 for filtration and removal. At 7:44, it can be seen that the air pollution value of the entire bathroom space A dropped rapidly, and the air pollution zeroing effect was maintained subsequently.

[0044] In order to understand the implementation of the air pollution prevention and control system for bathroom space of the present invention, the structure of the gas detector 1 of the present invention is described in detail as follows.

[0045] A gas detection module is arranged inside the gas detector 1, wherein the gas detection module comprises: a control circuit board 11, a gas detection body 12, a microprocessor 13 and a communicator 14. The gas detection body 12, the microprocessor 13 and the communicator 14 are packaged in the control circuit board 11 to form a whole and are electrically connected to each other. The microprocessor 13 and the communicator 14 are arranged on the control circuit board 11, and the microprocessor 13 controls the driving signal of the gas detection body 12 to start the detection operation, so that the gas detection body 12 detects air pollution and outputs a detection information, which is then processed by the microprocessor 13 and provided to the communicator 14 for external communication transmission, and transmitted to the cloud computing service device 4.

[0046] See also 4A to 9AAs shown, the gas detection body 12 comprises a base 121, a piezoelectric actuator 122, a driving circuit board 123, a laser assembly 124, a particle sensor 125 and an outer cover 126. The base 121 has a first surface 1211, a second surface 1212, a laser setting area 1213, an air inlet groove 1214, an air guide assembly bearing area 1215 and an air outlet groove 1216. The first surface 1211 and the second surface 1212 are two surfaces arranged opposite to each other. The laser assembly 124 is hollowed out from the first surface 1211 toward the second surface 1212. In addition, the outer cover 126 covers the base 121 and has a side plate 1261, and the side plate 1261 has an air inlet frame opening 1261a and an air outlet frame opening 1261b. The air inlet groove 1214 is formed by being recessed from the second surface 1212 and is adjacent to the laser setting area 1213. The air inlet groove 1214 is provided with an air inlet opening 1214a, which is connected to the outside of the base 121 and corresponds to the air inlet frame opening 1261a of the outer cover 126, and the two side walls of the air inlet groove 1214 are provided with light-transmitting windows 1214b that penetrate the piezoelectric actuator 122 and are connected to the laser setting area 1213. Therefore, the first surface 1211 of the base 121 is covered by the outer cover 126, and the second surface 1212 is covered by the driving circuit board 123, so that the air inlet groove 1214 defines an air inlet path.

[0047] The air guide component carrying area 1215 is formed by a depression of the second surface 1212, and is connected to the air inlet groove 1214, and has an air hole 1215a on the bottom surface, and each of the four corners of the air guide component carrying area 1215 has a positioning protrusion 1215b. The above-mentioned air outlet groove 1216 is provided with an air outlet port 1216a, and the air outlet port 1216a is correspondingly arranged with the air outlet frame port 1261b of the outer cover 126. The air outlet groove 1216 includes a first section 1216b formed by the vertical projection area of ​​the first surface 1211 being recessed to the air guide component bearing area 1215, and an area extending from the vertical projection area of ​​the air guide component bearing area 1215, and a second section 1216c formed by hollowing out from the first surface 1211 to the second surface 1212, wherein the first section 1216b is connected to the second section 1216c to form a step difference, and the first section 1216b of the air outlet groove 1216 is communicated with the air vent 1215a of the air guide component bearing area 1215, and the second section 1216c of the air outlet groove 1216 is communicated with the air outlet 1216a. Therefore, when the first surface 1211 of the base 121 is covered by the outer cover 126 and the second surface 1212 is covered by the driving circuit board 123, the air outlet groove 1216 and the driving circuit board 123 jointly define an air outlet path.

[0048] The laser assembly 124 and the particle sensor 125 are both disposed on the driving circuit board 123 and are located in the base 121. In order to clearly illustrate the positions of the laser assembly 124 and the particle sensor 125 and the base 121, the driving circuit board 123 is omitted. The laser assembly 124 is accommodated in the laser setting area 1213 of the base 121, and the particle sensor 125 is accommodated in the air intake groove 1214 of the base 121 and aligned with the laser assembly 124. In addition, the laser assembly 124 corresponds to the light-transmitting window 1214b, and the light-transmitting window 1214b allows the laser light emitted by the laser assembly 124 to pass through, so that the laser light is irradiated to the air intake groove 1214. The path of the light beam emitted by the laser assembly 124 is to pass through the light-transmitting window 1214b and form an orthogonal direction with the air intake groove 1214. The laser component 124 emits a light beam through the light-transmitting window 1214b into the air intake groove 1214. The gas in the air intake groove 1214 is irradiated. When the light beam contacts the gas, it is scattered and generates a projected light spot. The particle sensor 125 is located in its orthogonal direction and receives the projected light spot generated by the scattering for calculation to obtain gas detection data.

[0049] The piezoelectric actuator 122 is accommodated in the square gas guide component carrying area 1215 of the base 121. In addition, the gas guide component carrying area 1215 is connected to the air inlet groove 1214. When the piezoelectric actuator 122 is actuated, the gas in the air inlet groove 1214 is drawn into the piezoelectric actuator 122, and the gas passes through the vent hole 1215a of the gas guide component carrying area 1215 and enters the gas outlet groove 1216. In addition, the driving circuit board 123 is sealed on the second surface 1212 of the base 121. The laser component 124 is disposed on the driving circuit board 123 and is electrically connected. The particle sensor 125 is also disposed on the driving circuit board 123 and is electrically connected. When the outer cover 126 is covered on the base 121 , the air inlet frame opening 1261 a corresponds to the air inlet vent 1214 a of the base 121 , and the air outlet frame opening 1261 b corresponds to the air outlet vent 1216 a of the base 121 .

[0050] The piezoelectric actuator 122 comprises an air jet hole sheet 1221, a cavity frame 1222, an actuator 1223, an insulating frame 1224 and a conductive frame 1225. The air jet hole sheet 1221 is made of a flexible material and has a suspension sheet 1221a and a hollow hole 1221b. The suspension sheet 1221a is a sheet structure that vibrates in bending, and its shape and size correspond to the inner edge of the air guide component bearing area 1215, while the hollow hole 1221b runs through the center of the suspension sheet 1221a for gas circulation. In a preferred embodiment of the present invention, the shape of the suspension sheet 1221a can be one of a square, a figure, an ellipse, a triangle and a polygon.

[0051] The cavity frame 1222 is stacked on the jet hole sheet 1221, and its appearance corresponds to the jet hole sheet 1221. The actuator 1223 is stacked on the cavity frame 1222, and defines a resonance chamber 1226 between the cavity frame 1222 and the suspension sheet 1221a. The insulating frame 1224 is stacked on the actuator 1223, and its appearance is similar to the cavity frame 1222. The conductive frame 1225 is stacked on the insulating frame 1224, and its appearance is similar to the insulating frame 1224, and the conductive frame 1225 has a conductive pin 1225a and a conductive electrode 1225b, and the conductive pin 1225a extends outward from the outer edge of the conductive frame 1225, and the conductive electrode 1225b extends inward from the inner edge of the conductive frame 1225. In addition, the actuator 1223 further includes a piezoelectric carrier 1223a, an adjustment resonance plate 1223b and a piezoelectric plate 1223c. The piezoelectric carrier 1223a is stacked on the cavity frame 1222. The adjustment resonance plate 1223b is stacked on the piezoelectric carrier 1223a. The piezoelectric plate 1223c is stacked on the adjustment resonance plate 1223b. The adjustment resonance plate 1223b and the piezoelectric plate 1223c are accommodated in the insulating frame 1224. The piezoelectric plate 1223c is electrically connected to the conductive electrode 1225b of the conductive frame 1225. In a preferred embodiment of the present invention, the piezoelectric carrier 1223a and the adjustment resonance plate 1223b are both conductive materials. The piezoelectric carrier 1223a has a piezoelectric pin 1223d, and the piezoelectric pin 1223d and the conductive pin 1225a are connected to the 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 1223a, the adjustment resonance plate 1223b, the piezoelectric plate 1223c, the conductive electrode 1225b, the conductive frame 1225 and the conductive pin 1225a, and the conductive frame 1225 and the actuator 1223 are blocked by the insulating frame 1224 to avoid a short circuit, so that the driving signal can be transmitted to the piezoelectric plate 1223c. After receiving the driving signal, the piezoelectric plate 1223c is deformed due to the piezoelectric effect, and further drives the piezoelectric carrier 1223a and the adjustment resonance plate 1223b to generate reciprocating bending vibrations.

[0052] To further illustrate, the adjustment resonance plate 1223b is located between the piezoelectric plate 1223c and the piezoelectric carrier plate 1223a, and serves as a buffer between the two to adjust the vibration frequency of the piezoelectric carrier plate 1223a. Basically, the thickness of the adjustment resonance plate 1223b is greater than that of the piezoelectric carrier plate 1223a, and the vibration frequency of the actuator 1223 is adjusted by changing the thickness of the adjustment resonance plate 1223b.

[0053] Please refer to Fig. 7A , Figure 7B , Fig. 8A , Figure 8Band Fig. 9A As shown, the jet hole sheet 1221, the cavity frame 1222, the actuator 1223, the insulating frame 1224 and the conductive frame 1225 are stacked and positioned in sequence in the air guide component support area 1215, so that the piezoelectric actuator 122 is positioned in the air guide component support area 1215. The piezoelectric actuator 122 defines a gap 1221c between the suspension sheet 1221a and the inner edge of the air guide component support area 1215 for gas circulation. An airflow chamber 1227 is formed between the jet hole sheet 1221 and the bottom surface of the air guide component support area 1215. The airflow chamber 1227 is connected to the resonant chamber 1226 between the actuator 1223, the cavity frame 1222 and the suspension sheet 1221a through the hollow hole 1221b of the air jet hole sheet 1221. The vibration frequency of the gas in the resonant chamber 1226 is made close to the vibration frequency of the suspension sheet 1221a, so that the resonant chamber 1226 and the suspension sheet 1221a can generate a Helmholtz resonance effect, thereby improving the gas transmission efficiency. When the piezoelectric plate 1223c moves away from the bottom surface of the air guide component supporting area 1215, the piezoelectric plate 1223c drives the suspension plate 1221a of the jet hole plate 1221 to move away from the bottom surface of the air guide component supporting area 1215, so that the volume of the airflow chamber 1227 expands rapidly, the internal pressure drops to produce negative pressure, and the gas outside the piezoelectric actuator 122 flows in through the gap 1221c and enters the resonance chamber 1226 through the hollow hole 1221b, increasing the air pressure in the resonance chamber 1226 and thus producing a pressure gradient. When the piezoelectric plate 1223c drives the suspended plate 1221a of the jet hole plate 1221 to move toward the bottom surface of the air guide component supporting area 1215, the gas in the resonance chamber 1226 quickly flows out through the hollow hole 1221b, squeezing the gas in the air flow chamber 1227, and making the converged gas quickly and massively ejected out of the air hole 1215a of the air guide component supporting area 1215 in an ideal gas state close to Bernoulli's principle.

[0054] Through repetition Fig. 9B and Fig. 9CIn the action shown, the piezoelectric plate 1223c vibrates reciprocatingly. According to the inertia principle, the internal air pressure of the resonance chamber 1226 after exhaust is lower than the equilibrium air pressure, which will guide the gas to enter the resonance chamber 1226 again. In this way, the vibration frequency of the gas in the resonance chamber 1226 is controlled to be the same as the vibration frequency of the piezoelectric plate 1223c, so as to produce the Helmholtz resonance effect and realize the high-speed and large-volume transmission of the gas. The gas enters from the air inlet frame 1261a of the outer cover 126, enters the air inlet groove 1214 of the base 121 through the air inlet port 1214a, and flows to the position of the particle sensor 125. Furthermore, the piezoelectric actuator 122 is continuously driven to absorb gas from the air intake path, so that external gas can be quickly introduced and circulated stably, and pass through the top of the particle sensor 125. At this time, the laser component 124 emits a light beam through the light-transmitting window 1214b to enter the air intake groove 1214. The air intake groove 1214 passes above the particle sensor 125. When the light beam of the particle sensor 125 irradiates the suspended particles in the gas, scattering and projected light spots will occur. When the particle sensor 125 receives the projected light spots generated by the scattering, it calculates to obtain relevant information such as the particle size and concentration of the suspended particles contained in the gas, and the gas above the particle sensor 125 is also continuously driven by the piezoelectric actuator 122 and introduced into the vent 1215a of the air guide component supporting area 1215, and enters the air outlet groove 1216. Finally, when the gas enters the gas outlet groove 1216 , since the piezoelectric actuator 122 continuously delivers the gas into the gas outlet groove 1216 , the gas in the gas outlet groove 1216 will be pushed and discharged to the outside through the gas outlet port 1216 a and the gas outlet frame port 1261 b .

[0055] The gas detector 1 of the present invention can not only detect suspended particles in the gas, but also further detect the characteristics of the introduced gas, such as the gas is formaldehyde, ammonia, carbon monoxide, carbon dioxide, oxygen, ozone, etc. Therefore, the gas detector 1 of the present invention further includes a gas sensor 127, the gas sensor 127 is positioned and electrically connected to the driving circuit board 123, and is accommodated in the gas outlet groove 1216 to detect the characteristics of the introduced gas. The gas sensor 127 can be a volatile organic compound sensor to detect carbon dioxide or total volatile organic compound gas information; the gas sensor 127 can be a formaldehyde sensor to detect formaldehyde gas information; the gas sensor 127 can be a bacteria sensor to detect bacteria information or fungus information; the gas sensor 127 can be a virus sensor to detect virus gas information; the gas sensor 127 can be a temperature and humidity sensor to detect gas temperature and humidity information.

[0056] In summary, the present invention provides an air pollution prevention and control system for bathroom spaces. In order to solve the problem that indoor air pollution occurs at any time and moves at any time and is difficult to grasp, the present invention deploys multiple gas detectors in various outdoor and indoor fields, so that the gas detectors can determine the air pollution and output to form an air pollution information, which is then received and stored by a cloud computing service device to form a database of air pollution data. When the air pollution data in the bathroom space exceeds the safety detection value, the cloud computing service device issues a control instruction to control the exhaust fan to start the operation, and the air pollution in the bathroom space is drained and discharged outdoors. At the same time, it intelligently selects to issue another control instruction to transmit to the fan start operation of the filter device, so that the air pollution in the bathroom space can be quickly drained through the filter element of the filter device for filtration and removal, and the air pollution in the bathroom space can be controlled to approach the zero gas state, which is of great industrial utilization value.

[0057] Although the present invention has been disclosed as above with preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art may make some modifications and improvements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the definition of the claims.
