Description

[Technical field]

[0001] The present invention relates to an indoor air purification system, and in particular to an indoor air purification system suitable for achieving a clean room grade cleanliness in a gas state in an indoor space. [Background technology]

[0002] Suspended particulate matter refers to solid particles or liquid 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 the concentration of gas suspended particulate matter 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 particulate matter are mostly fixed points, it is impossible to confirm the concentration of suspended particulate matter in the surrounding area.

[0003] In addition, modern people are paying more and more attention to the quality of the air around them, such as carbon monoxide, carbon dioxide, volatile organic compounds (VOC), PM 2.5 , nitric oxide, sulfur oxide and other gases, and even the particles contained in the gases, will be exposed to the environment and affect human health, and even endanger life in serious cases. Therefore, the quality of environmental gases has attracted the attention of all countries. How to detect gas quality to avoid and stay away from areas with poor gas quality is a current topic 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 real-time precautions or escape, and avoid being harmed by the gas in the environment and causing health effects and injuries to the human body, using a gas sensor to detect the surrounding environment can be said to be a very good application.

[0005] In addition, indoor air quality is not easy to grasp. In addition to outdoor air quality, indoor air conditioning conditions and pollution sources are the main factors affecting indoor air quality. Indoor air pollution sources can be intelligently and quickly detected in various indoor fields, effectively removing indoor air pollution to form a clean and safe gas state, and indoor air quality can be monitored in real time anytime and anywhere. Of course, if the indoor space can strictly control the concentration of suspended particulates according to the "clean room" standard, strive to avoid the introduction, generation and retention of particles, and control the temperature and humidity within the required range, that is to say, the indoor space is distinguished by the number of suspended particles in the air, and the number of particles in 1 cubic meter is ≧0.5μm, so as to achieve the clean room requirements of indoor space that can be safely breathed; in addition, clean rooms can be divided into positive pressure and negative pressure. Generally, the semiconductor industry uses positive pressure type, which is mainly to prevent outdoor dust pollution. Negative pressure clean rooms are used in hospitals or some biotechnology plants because of the fear of bacteria leakage. Therefore, the indoor air pressure must be negative relative to the outdoor pressure. However, both positive pressure and negative pressure use a large amount of ventilation to achieve indoor cleanliness, and the cost of setting up multiple clean room equipment is quite expensive. It is difficult for ordinary consumers to accept and implement them in the indoor space of the home. Therefore, how to detect indoor air quality and how to solve the air pollution problem so that the indoor space can meet the requirements of a clean room and avoid the impact and harm to human health caused by the hazards of gases in the environment are the main topics developed by the present invention. [Summary of the invention]

Through the detection, purification and prevention efficiency of locating air pollution-draining air pollution-zeroing air pollution in the indoor field, the gas state of the indoor field can reach the cleanliness level of the clean room level.

[0007] To achieve the above-mentioned purpose, the present invention provides an indoor air purification system, comprising: at least one gas detector, which is arranged in an indoor field to detect an air pollutant and output to form an air pollution information; at least one purification device, which comprises a fan, a filter component and a sterilization component, wherein the fan is controlled to start and guide the air pollutant to pass through the filter component for filtration, and the air pollutant is sterilized and removed by the sterilization component, and the machine has a specific clean air output to generate a circulating directional airflow, and the filter component is a high-efficiency particulate air filter (HEPA); a cloud computing service device, which receives the air pollution information of the indoor field, stores a database of air pollution data, and intelligently selects to issue a control instruction based on the air pollution data to transmit to the fan of the purification device to start the operation, so that the indoor field generates a circulating directional airflow, and the air pollution in the indoor field is quickly guided to pass through the filter component for filtration and removal to zero multiple times and is sterilized and removed by the sterilization component, so that the gas state of the indoor field reaches the cleanliness level of the clean room.

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.

[0011] See also Figure 1 As shown, the present invention is an indoor air purification system, comprising: at least one gas detector 1, at least one purification device 2 and a cloud computing service device 3.

[0012] The gas detector 1 is arranged in an indoor field A to detect air pollution and output air pollution information. The gas detector 1 of the present invention is provided with a gas detection module. Please note that Figure 3A and Figure 3B As shown, the gas detector 1 can be a type of structure with an external power terminal, which can be directly plugged into the power interface in the indoor field A to start the operation of air pollution detection. Figure 3C The gas detection module shown does not include an external power terminal, is directly mounted on the device (purification device 2), and is connected to a power source to start the operation of detecting air pollution. 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.

[0013] The following is a detailed description of the gas detection module structure of the gas detector 1 of the present invention. Figures 3A to 11As shown, the gas detection module includes: 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 processed by the microprocessor 13 and provided to the communicator 14 for external communication transmission, and transmitted to the cloud computing service device 3. The communication transmission can be a wireless communication, and the wireless communication is one of a Wi-Fi module, a Bluetooth module, a wireless radio frequency identification module, and a near field communication module. In this way, the communicator 14 of the gas detection module and the cloud computing service device 3 are interconnected through the Internet (IOT).

[0014] Please see again 4A to 9A As 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 setting area 1213 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 1261a and an air outlet frame 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 port 1214a, which is connected to the outside of the base 121 and corresponds to the air outlet port 1216a of the outer cover 126, and the two side walls of the air inlet groove 1214 penetrate the light-transmitting window 1214b of 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.

[0015] 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.

[0016] 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, and the detection data in the gas in the air intake groove 1214 is irradiated. When the light beam contacts the gas, it will scatter and generate a projected light spot, so that the particle sensor 125 is located in its orthogonal direction and receives the projected light spot generated by the scattering for calculation to obtain the detection data of the gas.

[0017] 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 outlet 1216 a corresponds to the air inlet 1214 a of the base 121 , and the air outlet frame opening 1261 b corresponds to the air outlet 1216 a of the base 121 .

[0018] 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.

[0019] 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 actuator 1223, the jet hole sheet 1221, 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 extending outward from the outer edge of the conductive pin 1225a, 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 plate 1223a is stacked on the cavity frame 1222. The adjustment resonance plate 1223b is stacked on the piezoelectric carrier plate 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 plate 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.

[0020] 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.

[0021] Please refer to Fig. 7A , Figure 7B , Fig. 8A , Figure 8B and 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 airflow hole sheet 1221 and the suspension sheet 1221a through the hollow hole 1221b of the airflow 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.

[0022] By 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 1214a of the outer cover 126, enters the air inlet groove 1214 of the base 121 through the air inlet 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 air 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 .

[0023] 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 127a 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.

The fan 21 can be arranged in front of the filter assembly 22, or in the rear of the filter assembly 22.
