Description

Technical area

[0001] The present invention relates to an expandable cleaning device, and more particularly to an expandable cleaning device that is connected to an indoor air pollution control system for detecting and zero-pollution cleaning of air. [Background technology]

[0002] As people place increasing importance on the air quality in their living environment, they are increasingly exposed to particulate matter (PM) such as PM1, PM2.5, and PM10, gases such as carbon dioxide, total volatile organic compounds (TVOCs), and formaldehyde, as well as fine particles, aerosols, bacteria, and viruses contained in these gases, which can affect human health and, in serious cases, can be life-threatening.

[0003] The current indoor air quality is not easy to grasp. In addition to outdoor air quality, indoor environmental conditions and pollution sources are major factors that affect indoor air quality, especially dust, bacteria, and viruses that are generated by poor indoor air circulation.

[0004] In light of this situation, the realization of an indoor air pollution prevention system requires a solution that involves installing and purifying air purifiers to detect air pollution in indoor spaces and apply purification treatment to reduce air pollution to near-zero levels. Furthermore, the air pollution purification efficiency of typical purifiers in indoor spaces is approximately 20-1000, meaning that treating air pollution in indoor spaces requires a significant amount of time. To shorten the treatment time, it is necessary to increase the number of purifiers to improve treatment efficiency, but this increases installation costs, and increasing the number of purifiers too much results in wasteful installation costs. Furthermore, typical purifiers are unable to overcome the drawbacks of real-time monitoring and effective treatment anytime and anywhere. Therefore, in order to achieve optimal treatment efficiency and installation cost of purified air pollution in a large space, how to install the optimal purification device, realize an indoor air pollution prevention system by detecting air pollution in indoor spaces and applying purification treatment to reduce air pollution to near zero, provide a purification solution to reduce the inhalation of harmful gases indoors, and eliminate them through real-time detection and real-time monitoring, efficiently control the energy-saving effect of the operation of the purification device, and quickly purify indoor air are the main research topics of this invention. Summary of the Invention Problem to be solved

[0005] The primary objective of this invention is to provide an expandable purifying device that can be connected to an indoor air pollution control system and used for indoor air pollution detection and purification to reduce air pollution to near-zero levels. After the indoor air pollution control system's AI calculation determines the equivalent clean air delivery rate (CADR) demand, the air guide body has a guide channel that can be configured as an extended guide channel in the vertical and horizontal directions. This allows the required number of fans to be matched with the optimal CADR of the fans, resulting in an assembled purifying device that meets the equivalent clean air delivery rate (CADR) demand. Furthermore, a network-connected controller is installed and connected to the indoor air pollution control system, allowing indoor air quality to be monitored anytime and anywhere and the fan operation to be controlled in real time. At the same time, the system detects air pollution in the indoor space, intelligently compares it with the ambient air quality, and adjusts the fan's airflow volume in real time according to the air quality, thereby effectively controlling the energy-saving effects of the purifying device's operation. Furthermore, the optimum clean air delivery rate (CADR) of the fan combined with the induction channel is determined according to the upper limit of the allowable noise level and the allowable time requirement in the indoor space, and the fan startup operation effectively reduces the noise in the indoor space. In this way, the assembled expandable purification device detects air pollution in real time and performs zero-pollution purification treatment, achieving cleanroom-level cleanliness and its optimal installation cost-effectiveness. [Means for solving the problem]

[0006] In order to achieve the above object, one of the broader embodiments of the present application includes a guide body, at least one filtering element, at least one blower, and at least one network connection controller, the guide body having a guide passage that can be extended in a vertical direction / horizontal direction to form an extended guide path, the guide passage communicating with at least one intake port and at least one exhaust port to introduce air pollution into an indoor space, the filtering element being disposed in the guide passage and covering one side of the intake port to filter the air pollution drawn in from the indoor space, the blower having a predetermined clean air supply rate (CADR) being disposed in the guide passage to guide the air pollution into the guide passage and pass the air pollution through the filtering element to filter and purify the air pollution, and the network connection controller is configured to control network communication. The control command from the indoor air pollution prevention system is received via the control panel, and the start-up operation of the blower is performed. The equivalent of the clean air supply rate (CADR) required for the indoor space is determined by the smart (AI) calculation of the indoor air pollution prevention system. Based on the extended flow path formed by extending the flow path of the flow guide body in the vertical / horizontal directions, the number of blowers and the optimal clean air supply rate (CADR) of the blowers are matched and arranged to form an assembled expandable purification device that meets the required equivalent of the clean air supply rate (CADR). The assembled expandable purification device performs real-time detection of air pollution and purification treatment to reduce air pollution to near-zero, thereby providing an expandable purification device that achieves cleanroom-level cleanliness and optimal installation cost-effectiveness.

DETAILED DESCRIPTION OF THE INVENTION

[0008] Examples embodying the features of the present invention are set forth in detail in the following description. It is to be understood that the invention is susceptible to various changes in its various aspects without departing from the scope of the invention, and the descriptions and illustrations are illustrative in nature and not restrictive.

[0009] Please refer to Figures 1A to 1E. The present invention provides an expandable purifying device applicable to an indoor air pollution prevention system. The purifying device mainly includes a guide body 1, at least one filtering element 2, at least one fan 3, and at least one network-connected controller A. The guide body 1 has a guide passage 11 that can be extended vertically and horizontally to form an expandable guide path. The guide passage 11 communicates with at least one air intake 12 and at least one air exhaust 13 to introduce air pollution into the indoor space. The filtering element 2 is disposed in the guide passage 11 and covers one side of the air intake 12, passing and filtering the air pollution drawn from the indoor space. The fan 3 has a predetermined clean air supply rate (CADR) and is disposed in the guide passage 11. The filtering element 2 filters the air pollution into the guide passage 11, causing it to pass through the filtering element 2 for filtration, thereby purifying the air pollution to near-zero. The connection controller A receives control commands from the indoor air pollution prevention system B via network communication and starts the blowers 3. After the demand equivalent of the clean air supply rate (CADR) in the indoor space is determined by the smart (AI) calculation of the indoor air pollution prevention system B, the flow guide body 1 matches the number of blowers 3 to achieve the required equivalent and the optimal clean air supply rate (CADR) of the blowers 3 based on the vertical / horizontal expandable flow path of the flow guide passage 11, thereby forming an assembled purification device that meets the demand equivalent of the clean air supply rate (CADR), real-time detection of air pollution and purification treatment that reduces air pollution to near-zero, achieving cleanroom-level cleanliness and optimal installation cost-effectiveness.

[0010] The clean air delivery rate (CADR) of a single blower 3 is at least 150 m 3 / h or more.

[0011] From the above description, the expandable cleaning device provided by the present invention has an optimum required clean air delivery rate (CADR) of the blower 3 of 1200 m 3 / h, it can be seen that the following several combinations can be implemented.

[0012] 1. The leftmost single expandable cleaning device shown in FIG. 1A has a configuration in which the clean air supply rate (CADR) is 1200 m 3 The air conditioner is equipped with a single blower 3 with a capacity of 1 / h. The blower 3 introduces air pollution from intake ports 12 on both sides of the flow guide body 1, filters it by passing it through the filter member 2, and then introduces the purified gas back into the flow guide passage 11 and discharges it into the indoor space from the exhaust port 13 (see FIG. 1C).

[0013] 2. In the longitudinally extending assembly relationship of the expandable cleaning device according to the present invention shown in FIG. 1A, a plurality of blowers 3 are arranged in the guide passage 11 of the guide body 1. In the expandable cleaning device in the intermediate position shown in FIG. 1A, the clean air delivery rate (CADR) is 600 m 3 / h, or in the expandable purifier in the right position shown in Figure 1A, the clean air delivery rate (CADR) is 400 m 3 The air conditioner is equipped with three sets of fans 3, each with a capacity of 1 / h. The fans 3 filter air pollutants through the filter member 2 from the air intake ports 12 on both sides of the flow guide body 1 (see FIG. 1B), and introduce the purified gas into the flow guide passage 11, from which it is discharged into the indoor space through the three exhaust ports 13 on the front (see FIG. 1A).

[0014] 3. In the laterally extending assembly relationship of the expandable cleaning device according to the present invention shown in FIG. 1D, a plurality of blowers 3 are arranged in the guide passage 11 of the guide body 1. The clean air supply rate (CADR) is 600 m 3 Two sets of fans 3, each with a capacity of 1 / h, are combined. The fans 3 filter air pollutants through the filter member 2 from the air intake ports 12 on both sides of the flow guide body 1, and introduce the purified gas into the flow guide passage 11, from which it is discharged into the indoor space through the front and rear exhaust ports 13 (see Figure 1E).

[0015] Of course, the embodiment of the optimal required clean air supply rate (CADR) of the blower 3 of the expandable purifier is not limited to this. Multiple expandable purifiers can be arranged according to the actual available space in the indoor space, and the number of blowers 3 and the optimal CADR of the blowers 3 can be matched to the equivalent of the required clean air supply rate (CADR) in the indoor space to form an assembled purifier. This achieves the equivalent of the required clean air supply rate (CADR) in the indoor space, purifies the air to near-zero pollution, achieves cleanroom-level cleanliness, and optimizes installation cost-effectiveness. The arrangement of the air guide passage 11 of each individual purifier and the optimal CADR of the blower 3 can be determined according to the maximum allowable noise level and allowable time requirements in the indoor space. For example, if the upper limit of the allowable noise level in an indoor space is 70 dB and the allowable time is 3 minutes, the optimal required clean air delivery rate (CADR) of a single blower 3 in the assembled cleaning device is 1200 m 3 / h. If the start-up operation of the blower 3 is not suitable for the upper limit of the allowable noise level of 70 dB and the allowable operation time of 3 minutes, the expandable cleaning device is designed to have a clean air delivery rate (CADR) of 600 m / h based on the expansion flow path of the flow path 11 in the vertical and horizontal directions. 3 The air purifier can be assembled by selecting and matching two sets of blowers 3 with a capacity of 1200 m / h. This allows the start-up operation of the blowers 3 to be below the allowable noise limit of 70 dB and the allowable operation time of 3 minutes, while achieving an optimal required clean air delivery rate (CADR) of 1200 m / h. 3 / h, the cleaning process can be performed to reduce air pollution to near zero, achieving the required clean room level of cleanliness. Of course, the expandable cleaning device can be configured to have a clean air delivery rate (CADR) of 400 m / s based on the expansion of the vertical / horizontal flow path of the flow path 11. 3 The cleaning device is constructed by selecting, matching, and assembling three sets of blowers 3 with a capacity of 1200 m / h, and the start-up operation of the blowers 3 is below the allowable noise limit of 70 dB and the allowable operation time of 3 minutes, while achieving an optimal required clean air supply rate (CADR) of 1200 m 3A cleaning process that reduces air pollution to near-zero with a demand equivalent of 10 ...

[0016] From the above description, the expandable purifier provided by the present invention can configure an assembled purifier that meets the demand equivalent of the clean air supply rate (CADR) based on the required number of blowers 3 and the optimal clean air supply rate (CADR) of the blowers 3, using the guide channel 11 in which the guide body 1 can be extended in the vertical and horizontal directions to form an expandable guide channel. The equivalent of the clean air supply rate (CADR) required in an indoor space is determined through intelligent (AI) calculations in the big data database of the indoor air pollution prevention system B by connecting the expandable purifier provided by the present invention to the indoor air pollution prevention system B via the network connection controller A. This allows the number of assembled purifiers to be arranged according to the demand equivalent of the clean air supply rate (CADR), the number of blowers 3 for each assembled purifier, and the optimal clean air supply rate (CADR). This makes it possible to monitor the air quality in the indoor space anytime and anywhere, simultaneously detect air pollution in the indoor space, intelligently compare it with the state of the ambient air quality, and control the airflow volume of the fan 3 in real time according to the air quality, thereby effectively controlling the energy-saving effect of the operation of the purifier.

[0017] The following is an illustrative description of a preferred embodiment of the expandable cleaning device provided by the present invention.

[0018] The number of fans 3 of the expandable purifier provided by the present invention and the optimal clean air supply rate (CADR) can be determined and arranged according to the demand equivalent of the clean air supply rate (CADR) through smart (AI) calculations of the big data database of the indoor air pollution prevention system B. In this indoor air pollution prevention system B, the required number of fans 3 of the expandable purifier and the optimal clean air supply rate (CADR) can be obtained simply by inputting the area of ​​the indoor space.

[0019] For example, if the indoor space is in the Taipei area, it is 3 ping (approximately 26.7 m 3 If it is necessary to achieve ZAP Clean Room 9 cleanliness in a space of 1000 m², the process for calculating the required number of blowers 3 of the expandable cleaning device and the optimum clean air supply rate (CADR) value is as follows: The big data database of the air pollution prevention system B can perform smart calculation analysis based on the equivalent comparison table of the required clean air supply rate (CADR) per cubic meter for clean room grades ZAP Clean Room 1 to 12 shown in Figure 12. Note that the equivalent of the required clean air supply rate (CADR) per cubic meter for the clean room grades ZAP Clean Room 1 to 12 of the present invention is as follows: The equivalent range of the clean air supply rate (CADR) per cubic meter for clean room grade ZAP Clean room 1 is 195,000 to 370,000 m 3 / h; The equivalent range of the clean air supply rate (CADR) per cubic meter for clean room grade ZAP Clean room 2 is 58,000 to 115,000 m 3 / h; The equivalent range of the clean air supply rate (CADR) per cubic meter for clean room grade ZAP Clean room 3 is 17,500 to 35,000 m 3 / h; The equivalent range of the clean air supply rate (CADR) per cubic meter for clean room grade ZAP Clean room 4 is 5200 to 10000 m3 / h; The equivalent range of the clean air supply rate (CADR) per cubic meter for clean room grade ZAP Clean room 5 is 1500 to 3000 m 3 / h; The equivalent range of the clean air supply rate (CADR) per cubic meter for clean room grade ZAP Clean room 6 is 450 to 1000 m 3 / h; The equivalent range of the clean air supply rate (CADR) per cubic meter for clean room grade ZAP Clean room 7 is 135 to 300 m 3 / h; The equivalent range of the clean air supply rate (CADR) per cubic meter for clean room grade ZAP Clean room 8 is 60 to 135 m 3 / h; The equivalent range of the clean air supply rate (CADR) per cubic meter for clean room grade ZAP Clean room 9 is 35 to 80 m 3 / h; The equivalent range of the clean air supply rate (CADR) per cubic meter for clean room grade ZAP Clean room 10 is 15 to 40 m 3 / h; The equivalent range of the clean air supply rate (CADR) per cubic meter for clean room grade ZAP Clean room 11 is 10 to 30 m 3 / h; The equivalent range of the clean air supply rate (CADR) per cubic meter for clean room grade ZAP Clean room 12 is 3 to 10 m 3 / h. By entering "Taipei" as the indoor space region, the big data database of Air Pollution Prevention System B can retrieve, based on the entered location, that the maximum PM2.5 value in the Taipei area over the past five years is 37 and the average value is 11.9. In this case, the average value of 11.9 is within the range of 10 to 15 in the comparison table for average values, and the ratio of the maximum value 37 to the average value 11.9 is 3.1, which is within the range of 3 to 4 in the comparison table for average values ​​10 to 15, and corresponds to column 2. In addition, since this example requires a cleanliness level of ZAP Clean Room 9, it can be seen that the equivalent required clean air supply rate (CADR) per cubic meter of cleanliness level of ZAP Clean Room 9 in this indoor space area is 56.26 m3 / h. The required indoor space is 3 tsubo (26.7 m 3 ), so this is 56.26m 3 / h, the equivalent clean air delivery rate (CADR) required for this required indoor space is 1502 m 3 / h. Therefore, the optimum clean air delivery rate (CADR) of the blower 3 of the expandable cleaning device of the present invention, which performs cleaning treatment to reduce air pollution to near zero, is 1500 m 3 / h.

[0020] From the above example, if the indoor space is in the Taipei area and requires ZAP Clean Room Class 9 cleanliness in a 3-ping space, the optimal clean air delivery rate (CADR) of blower 3 of the expandable purifier is 1500 m 3 Therefore, considering the layout of the indoor space, the assembled purifier has an optimum required clean air delivery rate (CADR) of 1500 m3 / h for a single blower 3. 3 Considering the arrangement in which the start-up operation of the blower 3 exceeds the allowable noise limit of 70 dB and the allowable operation time of 3 minutes, the expandable purifier can be set to have a clean air delivery rate (CADR) of 800 m / h based on the vertical and horizontal expansion paths of the guide passage 11. 3 / h and 700m 3 It is preferable to configure the purifier by assembling two sets of blowers 3, each with a fan speed of 100 rpm / h. This ensures that the start-up operation of the blowers 3 is below the allowable noise limit of 70 dB and the allowable operation time of 3 minutes. Of course, if the layout of the indoor space is not taken into consideration, the fan speed is 300 m / s. 3By arranging five sets of single blowers 3 with an optimal required clean air supply rate (CADR) of 1 / h, a cleaning process that reduces air contamination to near zero can be achieved, thereby achieving the required clean room level of cleanliness.

[0021] As a result, it can be seen that the expandable purifying device provided by the present invention is connected to an indoor air pollution prevention system B and is used to detect air pollution in indoor spaces and purify the air to near-zero levels. The air guide body 1 is equipped with a guide channel 11 that can be extended vertically and horizontally to form an expandable air guide path, thereby forming an assembled purifying device that meets the demand equivalent of the clean air supply rate (CADR) based on the required number of blowers 3 and the optimal clean air supply rate (CADR) of the blowers 3. Furthermore, a network-connected controller A is installed and connected to the indoor air pollution prevention system, allowing indoor air quality to be monitored anytime and anywhere and the activation of the blowers 3 to be controlled in real time. At the same time, the system detects air pollution in the indoor space, intelligently compares it with the ambient air quality, and adjusts the airflow rate of the blowers 3 in real time according to the air quality, thereby effectively controlling the energy-saving effect of the purifying device's operation. After the indoor air pollution prevention system B's intelligent (AI) calculation determines the indoor space's required clean air delivery rate (CADR), the guide body 1 is configured to match the number of fans 3 and their optimal CADR based on the vertical and horizontal expansion paths of the guide channel 11, forming an assembled purifier that meets the required CADR. Furthermore, the optimal CADR of the required fans 3 in the guide channel 11 is also configured according to the indoor space's allowable noise limit and allowable time requirements, effectively reducing noise within the indoor space when the fans 3 are activated. In this way, the assembled purifier, configured with the expandable purifier, achieves real-time detection of air pollution and purification treatment that reduces air pollution to near-zero, achieving cleanroom-level cleanliness and optimal installation cost-effectiveness.

[0022] The network-connected controller A includes a driver 4 and a gas detection module 5. The driver and gas detection module are electrically connected to each other and controlled. The driver 4 receives control commands from the indoor air pollution prevention system B via network communication and controls the opening and closing of the blower 3. In addition, the gas detection module 5 detects air pollution in monitoring mode, outputs gas detection data, and communicates bidirectionally with the indoor air pollution prevention system B via network communication. The indoor air pollution prevention system B receives the gas detection data, performs intelligent comparison, and issues a driving command. The gas detection module 5 receives the driving command and controls the opening and closing of the blower 3 and the adjustment of the airflow volume of the blower 3.

[0023] The air pollution may be any one or a combination of suspended particulate matter, carbon monoxide, carbon dioxide, ozone, sulfur dioxide, nitrogen dioxide, lead, total volatile organic compounds, formaldehyde, bacteria, and fungal viruses. The monitoring mode state is a monitoring mode operation to determine whether the detected air pollution gas detection data exceeds a safe detection value. This safe detection value is a value where the concentration of suspended particulate matter 2.5 (PM2.5) exceeds 15 μg / m. 3 carbon dioxide (CO2) concentration less than 1000 ppm, total volatile organic compounds (TVOC) concentration less than 0.56 ppm, formaldehyde (HCHO) concentration less than 0.08 ppm, bacterial count less than 1500 CFU / m 3 Less than 1000 CFU / m 3 less 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 0.1 μg / m 3 At least one of the following is true:

[0024] The above intelligent comparison is performed by the gas detection module 5 of the network-connected controller A detecting gas detection data, and then the indoor air pollution prevention system B receiving the gas detection data, connecting to the cloud device, intelligently calculating and comparing it with the detected gas detection data, and intelligently selecting and issuing a driving command, which is received by the gas detection module 5 of the network-connected controller A. That is, it intelligently judges and issues a driving command to start the fan 3 or adjust the airflow volume. The greater the gas detection data is above the safe detection value, the greater the adjustment of the airflow volume of the fan 3; and the closer the gas detection data is to the safe detection value, the less the adjustment of the airflow volume of the fan 3 is.

[0025] With the understanding that the installation of the expandable cleaning device of the present invention can realize real-time detection of air pollution in indoor spaces and cleaning treatment to bring air pollution close to zero, the internal structure and operation of the gas detection module 5 will be described below.

[0026] 2 and 11, the gas detection module 5 includes a control circuit board 51, a gas detection main body 52, a microprocessor 53, and a communication device 54. The gas detection main body 52, microprocessor 53, and communication device 54 are integrally packaged on the control circuit board 51 and are electrically connected to each other. The microprocessor 53 controls the detection operation of the gas detection main body 52, which detects air pollution and outputs a detection signal. The microprocessor 53 receives the detection signal, performs calculations, and generates air pollution data, which is provided to the communication device 54 and transmitted to the indoor air pollution prevention system B via external communication.

[0027] See Figures 3A, 3B, and 4 to 10C. The gas detection main body 52 includes a base 521, a piezoelectric actuator 522, a drive circuit board 523, a laser member 524, a particle sensor 525, and an outer cover 526. The base 521 has a first surface 5211, a second surface 5212, a laser mounting area 5213, an air intake groove 5214, an air guide member mounting area 5215, and an exhaust groove 5216. The first surface 5211 and the second surface 5212 are two opposing surfaces. The laser mounting area 5213 is formed by hollowing out from the first surface 5211 toward the second surface 5212. The outer cover 526 covers the base 521 and has a side plate 5261 with an air intake frame opening 5261a and an exhaust frame opening 5261b. The air intake groove 5214 is recessed from the second surface 5212 and is adjacent to the laser installation area 5213. The air intake groove 5214 is provided with an air intake passage opening 5214a that communicates with the outside of the base 521 and corresponds to the air intake frame opening 5261a of the outer lid 526. Both side walls of the air intake groove 5214 are penetrated by transmission windows 5214b that communicate with the laser installation area 5213. Therefore, the first surface 5211 of the base 521 is covered by the outer lid 526, and the second surface 5212 is covered by the drive circuit board 523, thereby defining an air intake path by the air intake groove 5214.

[0028] The air guide member mounting area 5215 is recessed from the second surface 5212 and communicates with the intake groove 5214. An air vent 5215a penetrates the bottom surface, and positioning protrusions 5215b are provided at each of the four corners of the air guide member mounting area 5215. The exhaust groove 5216 is provided with an exhaust passage opening 5216a, which is positioned corresponding to the exhaust frame opening 5261b of the outer lid 526. The exhaust groove 5216 includes a first section 5216b formed by recessing the first surface 5211 with respect to the vertical projection area of ​​the air guide member mounting area 5215, and a second section 5216c formed by hollowing out from the first surface 5211 toward the second surface 5212 in an area extending from the vertical projection area of ​​the air guide member mounting area 5215. The first section 5216b and the second section 5216c are connected by forming a step. The first section 5216b of the exhaust groove 5216 communicates with the ventilation hole 5215a of the air conducting member mounting area 5215, and the second section 5216c of the exhaust groove 5216 communicates with the exhaust passage opening 5216a. Therefore, when the first surface 5211 of the base 521 is covered by the outer lid 526 and the second surface 5212 is covered by the drive circuit board 523, the exhaust groove 5216 and the drive circuit board 523 together define an exhaust path.

[0029] The laser member 524 and the particle sensor 525 are both mounted on a driving circuit board 523 and located within the base 521. To clearly illustrate the positions of the laser member 524, the particle sensor 525, and the base 521, the driving circuit board 523 is intentionally omitted. The laser member 524 is accommodated within a laser installation area 5213 of the base 521, and the particle sensor 525 is accommodated within an air intake groove 5214 of the base 521 and aligned with the laser member 524. Furthermore, the laser member 524 corresponds to a transmission window 5214b, which allows the laser light emitted by the laser member 524 to pass through and irradiate the air intake groove 5214. The light beam path emitted from the laser member 524 passes through the transmission window 5214b and forms a direction perpendicular to the air intake groove 5214. The laser member 524 emits a light beam through the transmission window 5214b into the intake groove 5214, irradiating the gas in the intake groove 5214. When the light beam comes into contact with the gas, it scatters to generate a projection spot, and the particle sensor 525, located at a position perpendicular to the gas, receives the projection spot generated by scattering and performs calculations to obtain gas detection data. In addition, the gas sensor 527 is positioned on and electrically connected to the drive circuit board 523 and housed in the intake groove 5214 to detect air pollution introduced into the intake groove 5214. In a preferred embodiment of the present invention, the gas sensor 527 is a volatile organic compound sensor for detecting carbon dioxide or total volatile organic compound gas information, a formaldehyde sensor for detecting formaldehyde gas information, a bacteria sensor for detecting bacteria and fungi information, or a virus sensor for detecting virus gas information.

[0030] The piezoelectric actuator 522 is accommodated in a square air guide mounting area 5215 of the base 521. The air guide mounting area 5215 is connected to the air intake groove 5214. When the piezoelectric actuator 522 is activated, gas in the air intake groove 5214 is drawn into the piezoelectric actuator 522, and the gas passes through the vent hole 5215a of the air guide mounting area 5215 and enters the exhaust groove 5216. The driving circuit board 523 is covered by the second surface 5212 of the base 521. The laser element 524 is mounted on and electrically connected to the driving circuit board 523. The particle sensor 525 is also mounted on and electrically connected to the driving circuit board 523. When the outer cover 526 covers the base 521, the air intake frame opening 5261a corresponds to the air intake passage opening 5214a of the base 521, and the exhaust frame opening 5261b corresponds to the exhaust passage opening 5216a of the base 521.

[0031] The piezoelectric actuator 522 includes a blowhole plate 5221, a chamber frame 5222, an actuator body 5223, an insulating frame 5224, and a conductive frame 5225. The blowhole plate 5221 is made of a flexible material and has a floating plate 5221a and a hollow hole 5221b. The floating plate 5221a is a sheet-like structure that vibrates in a bending manner, and its shape and size correspond to the inner edge of the air-conducting member mounting area 5215. The hollow hole 5221b penetrates the center of the floating plate 5221a to allow gas to flow through. In a preferred embodiment of the present invention, the shape of the floating plate 5221a may be any one of a rectangle, a figure, an ellipse, a triangle, and a polygon.

[0032] The chamber frame 5222 is stacked on the blast hole plate 5221, and its appearance corresponds to that of the blast hole plate 5221. The actuator body 5223 is stacked on the chamber frame 5222, and defines a resonance chamber 5226 between the chamber frame 5222 and the floating plate 5221a. The insulating frame 5224 is stacked on the actuator body 5223, and its appearance is similar to that of the chamber frame 5222. The conductive frame 5225 is stacked on the insulating frame 5224, and its appearance is similar to that of the insulating frame 5224. The conductive frame 5225 has a conductive pin 5225a and a conductive electrode 5225b. The conductive pin 5225a extends outward from the outer edge of the conductive frame 5225, and the conductive electrode 5225b extends inward from the inner edge of the conductive frame 5225. Furthermore, the actuator body 5223 includes a piezoelectric carrier plate 5223a, a resonance adjustment plate 5223b, and a piezoelectric plate 5223c. The piezoelectric carrier plate 5223a is laminated on the chamber frame 5222. The resonance adjustment plate 5223b is laminated on the piezoelectric carrier plate 5223a. The piezoelectric plate 5223c is laminated on the resonance adjustment plate 5223b. The resonance adjustment plate 5223b and the piezoelectric plate 5223c are housed in an insulating frame 5224. The piezoelectric plate 5223c is electrically connected to the piezoelectric plate 5223c by a conductive electrode 5225b of a conductive frame 5225. In a preferred embodiment of the present invention, the piezoelectric carrier plate 5223a and the resonance adjustment plate 5223b are both made of conductive materials. The piezoelectric carrier plate 5223a has piezoelectric pins 5223d, which are connected to the conductive pins 5225a and a drive circuit (not shown) on the drive circuit board 523 to receive a drive signal (which may be a drive frequency and a drive voltage). The drive signal can form a loop through the piezoelectric pins 5223d, the piezoelectric carrier plate 5223a, the resonance adjustment plate 5223b, the piezoelectric plate 5223c, the conductive electrode 5225b, the conductive frame 5225, and the conductive pins 5225a, and the insulating frame 5224 isolates the conductive frame 5225 from the actuator body 5223 to prevent a short circuit from occurring, allowing the drive signal to be transmitted to the piezoelectric plate 5223c.When the piezoelectric plate 5223c receives a drive signal, it deforms due to the piezoelectric effect, and further drives the piezoelectric carrier plate 5223a and the resonance adjustment plate 5223b to generate reciprocating bending vibration.

[0033] More specifically, the resonance adjusting plate 5223b is located between the piezoelectric plate 5223c and the piezoelectric carrier plate 5223a, functions as a buffer between them, and can adjust the vibration frequency of the piezoelectric carrier plate 5223a. Basically, the thickness of the resonance adjusting plate 5223b is greater than that of the piezoelectric carrier plate 5223a, and the vibration frequency of the actuator body 5223 can be adjusted by changing the thickness of the resonance adjusting plate 5223b.

[0034] See Figures 7A, 7B, 8A, 8B, and 9. The blast hole plate 5221, chamber frame 5222, actuator body 5223, insulating frame 5224, and conductive frame 5225 are stacked in this order and positioned within the air guide member mounting area 5215. Thus, the piezoelectric actuator 522 is positioned within the air guide member mounting area 5215, and the piezoelectric actuator 522 defines a gap 5221c for gas communication between the floating plate 5221a and the inner edge of the air guide member mounting area 5215. An airflow chamber 5227 is formed between the blast hole plate 5221 and the bottom surface of the air guide member mounting area 5215. The airflow chamber 5227 communicates with a resonance chamber 5226 between the actuator body 5223, chamber frame 5222, and floating plate 5221a via a hollow hole 5221b in the blast hole plate 5221. By bringing the vibration frequency of the gas in the resonating chamber 5226 closer to the vibration frequency of the floating plate 5221a, the resonating chamber 5226 and the floating plate 5221a generate a Helmholtz resonance effect, thereby increasing the gas transmission efficiency. When the piezoelectric plate 5223c moves in a direction away from the bottom surface of the air-conducting member mounting area 5215, the volume of the airflow chamber 5227 suddenly expands, the internal pressure decreases, and negative pressure occurs. Gas outside the piezoelectric actuator 522 flows in through the gap 5221c and enters the resonating chamber 5226 via the hollow hole 5221b, increasing the air pressure in the resonating chamber 5226 and generating a pressure gradient. When the piezoelectric plate 5223c moves the floating plate 5221a of the blower hole plate 5221 toward the bottom surface of the air-conducting member mounting area 5215, the gas in the resonance chamber 5226 rapidly flows out through the hollow hole 5221b, pushing out the gas in the airflow chamber 5227, and the combined gas is ejected quickly and in large quantities in an ideal gas state close to Bernoulli's theorem, and introduced into the air vent 5215a of the air-conducting member mounting area 5215.

[0035] 9B and 9C, the piezoelectric plate 5223c vibrates back and forth. According to the principle of inertia, when the internal air pressure of the resonating chamber 5226 after exhaust falls below the equilibrium pressure, gas is reintroduced into the resonating chamber 5226. In this way, the vibration frequency of the gas in the resonating chamber 5226 is controlled to approach the vibration frequency of the piezoelectric plate 5223c, generating the Helmholtz resonance effect and achieving high-speed, large-volume gas transmission. All gas enters through the intake frame opening 5261a of the outer cover 526, passes through the intake passage opening 5214a, enters the intake groove 5214 of the base 521, and flows to the position of the particle sensor 525. Furthermore, the continuous drive of the piezoelectric actuator 522 draws in gas from the intake path, allowing external gas to be rapidly introduced and circulate steadily, passing above the particle sensor 525. At this time, the light beam emitted by the laser member 524 passes through the transparent window 5214b, irradiates the intake groove 5214, and passes above the particle sensor 525. When the light beam from the particle sensor 525 is irradiated on particles suspended in the gas, it scatters and generates a projection spot. The particle sensor 525 receives the projection spot generated by scattering and performs calculations to obtain relevant information such as the particle size and concentration of the particles suspended in the gas. The gas above the particle sensor 525 is also guided by the continuous driving of the piezoelectric actuator 522 through the ventilation hole 5215a of the air guide member mounting area 5215 and enters the exhaust groove 5216. Finally, after the gas enters the exhaust groove 5216, the piezoelectric actuator 522 continues to transport the gas to the exhaust groove 5216, pushing the gas out of the exhaust groove 5216 and exhausting it to the outside through the exhaust passage opening 5216a and the exhaust frame opening 5261b.

[0036] The gas detection module 5 of the present invention not only includes a particulate sensor 525 capable of detecting information on suspended particulates in gas (such as PM1, PM2.5, and PM10), but also detects characteristics of introduced gas, such as formaldehyde, ammonia, carbon monoxide, carbon dioxide, oxygen, and ozone. Therefore, the gas detection module 5 of the present invention further includes a gas sensor 527, which is positioned and electrically connected to the drive circuit board 523, housed in the exhaust groove 5216, and detects gases contained in the gas discharged from the exhaust path. The gas sensor 527 may include a volatile organic compound sensor for detecting carbon dioxide or total volatile organic compound gas information. The gas sensor 527 may include a formaldehyde sensor for detecting formaldehyde gas information. The gas sensor 527 may include a bacteria sensor for detecting bacterial or fungal information. The gas sensor 527 may include a virus sensor for detecting viral gas information.

In the present invention, a high efficiency air filter 13 (HEPA 13) is used, and its dust collection capacity is 12,000 mg or more. The filter element 2 may be activated carbon. The activated carbon has a formaldehyde absorption capacity of 1,500 mg or more. The activated carbon removes organic and inorganic substances in air pollution and removes colored and odorous substances, thereby absorbing 1,500 mg or more of formaldehyde from the introduced air pollution and achieving a filtering and purification effect. The filter element 2 may be a photocatalyst. The photocatalyst may be an ultraviolet (UVC) lamp with a power of 120 mW or more.

[0038] Based on the above, the present invention provides an expandable purifying device that can be connected to an indoor air pollution control system and used for indoor air pollution detection and purification to reduce air pollution to near-zero levels. After the indoor air pollution control system's AI calculation determines the equivalent clean air delivery rate (CADR) demand, the air guide body has a guide passage that can form an extended guide path in the vertical and horizontal directions. This allows the required number of fans to be matched with the optimal clean air delivery rate (CADR) of the fans, resulting in an assembled purifying device that meets the equivalent clean air delivery rate (CADR) demand. Furthermore, a network-connected controller is installed and connected to the indoor air pollution control system, allowing indoor air quality to be monitored anytime and anywhere and the fan operation to be controlled in real time. At the same time, the system detects air pollution in the indoor space, intelligently compares it with the ambient air quality, and adjusts the fan's airflow volume in real time according to the air quality, thereby effectively controlling the energy conservation of the purifying device's operation. Furthermore, the optimal clean air supply rate (CADR) of the blower combined with the induction channel is determined according to the upper limit of the allowable noise level and the allowable time requirement in the indoor space, and the start-up operation of the blower effectively reduces noise in the indoor space. In this way, the assembled expandable purification device detects air pollution in real time, purifies air pollution to zero, and achieves cleanroom-level cleanliness and optimal installation cost-effectiveness, making it highly applicable in industry.
