[0038] To better understand the technical content of this invention, preferred embodiments are described below.
[0039] Please refer to the following as well. Figures 1 to 2 An intelligent fume hood according to an embodiment of the present invention. Figure 1 A schematic diagram of an embodiment of the present invention, showing an intelligent fume hood. Figure 2 A system architecture diagram of an embodiment of the present invention, comprising an intelligent fume hood, an external computer, an electronic tag reader / writer, and a blockchain network.
[0040] like Figures 1 to 2 As shown, in one embodiment of this invention, the intelligent fume hood 1 facilitates the traceability of the source of the experimental liquid and the detection of the gas properties of the experimental waste gas. The intelligent fume hood 1 is used to hold an experimental liquid 900 and extract an experimental waste gas 910 generated by the experimental liquid 900. It is connected to an external computer 200 and a blockchain network 400 to transmit relevant information about the intelligent fume hood 1 and the contained experimental liquid 900 to the external computer 200 and the blockchain network 400. The experimental liquid 900 is a volatile chemical liquid that produces experimental waste gas 910. In this embodiment, the experimental liquid 900 is, for example, ammonia water, which volatilizes to produce ammonia gas, the pungent odor of the experimental waste gas 910. However, the type of experimental liquid 900 is not limited to the above and can be changed according to actual usage requirements. The external computer 200 is, for example, a desktop computer or laptop, used to exchange data with the intelligent fume hood 1. The blockchain network 400 is an external network system that uses blockchain technology to establish and store a chain of data.
[0041] In an embodiment of the present application, the intelligent fume hood 1 comprises a fume hood 10, a chip set 20, a detection module 30, a wireless module 40, a battery 50 and a screen 60. The fume hood 10 is a cabinet with ventilation function, for placing experimental liquid 900 by the worker and extracting experimental exhaust gas 910 generated by the experimental liquid 900. The fume hood 10 comprises an experimental tank 11, a movable door 12 and an exhaust pump 13. The experimental tank 11 is used for placing the container (such as beaker or test tube) filled with experimental liquid 900 by the worker. The chip set 20, the detection module 30, the wireless module 40, the battery 50 and the screen 60 are arranged in the experimental tank 11; the detection module 30 is arranged on the bottom surface of the experimental tank 11. The movable door 12 is a transparent glass or acrylic door, which is movable to connect the experimental tank 11. The movable door 12 is used to cover the experimental tank 11, so that the experimental tank 11 is sealed to avoid the experimental exhaust gas 910 overflowing to cause air pollution. The exhaust pump 13 has a ventilation pipe 131 to communicate with the experimental tank 11. The exhaust pump 13 is electrically connected to the detection module 30. The exhaust pump 13 is used to extract the experimental exhaust gas in the experimental tank 11 to the external gas filtering chamber and then disperse to the atmosphere, so that the experimental exhaust gas 910 can be filtered into harmless gas, and the experimental exhaust gas 910 can be avoided to be inhaled by the experimental personnel to affect the health.
[0042] In an embodiment of the present disclosure, the chip set 20 is disposed in the experiment tank 11 of the fume hood 10. The chip set 20 comprises a blockchain information tracing element 21, a positioning element 22, a temperature detecting element 23, and an electronic tag element 24. The blockchain information tracing element 21 is a computing chip which is signal connected with a blockchain network 400 and transmits and records data in the blockchain network 400, and can also trace the data previously recorded in the blockchain network 400. For example, the blockchain information tracing element 21 can record the source and circulation history of the experimental liquid 900 in the blockchain network 400. By using the traceable and unalterable characteristics of the blockchain, the source and circulation history of the experimental liquid 900 can be recorded and tracked. The blockchain information tracing element 21 can also trace the source and circulation history of the experimental liquid 900 recorded in the blockchain network 400. According to an embodiment of the present disclosure, the source of the experimental liquid 900 is, for example, from a chemical laboratory or a pharmaceutical factory. The circulation history of the experimental liquid 900 includes the location of obtaining the experimental liquid 900, the logistics process of transporting the experimental liquid 900, the location of manufacturing and storing the experimental liquid 900, and the like. In addition, the source and circulation history of the experimental liquid 900 can also be input into the blockchain information tracing element 21 by the external computer 200, and then recorded in the blockchain network 400 by the blockchain information tracing element 21. In this way, by using the traceable and unalterable characteristics of the blockchain, the source and circulation history of the experimental liquid 900 can be clearly recorded and managed. The positioning element 22 is a global positioning system (GPS) chip which is used to locate the smart fume hood 1 to determine the current position of the smart fume hood 1. The temperature detecting element 23 is a chip with temperature sensing function which is used to detect the temperature of the smart fume hood 1, so that whether the smart fume hood 1 is in a suitable temperature environment can be monitored to avoid the influence of overheating or overcooling environment on the quality of the experimental liquid 900. The electronic tag element 24 records the information of the smart fume hood 1 and / or the experimental liquid 900 in a radio frequency identification (RFID) manner, such as the manufacturing date of the smart fume hood 1, the date and location of using the smart fume hood 1 to conduct experiments with the experimental liquid 900, the type of the experimental liquid 900, and the like. The information recorded by the electronic tag element 24 can be input by the external computer 200. However, the information of the smart fume hood 1 is not limited to the above, and can be changed according to design requirements. The information recorded by the electronic tag element 24 can also be read by an external electronic tag reader / writer 300 through radio signals. However, the electronic tag reader / writer 300 has been widely used in the field of radio frequency technology, and is not the focus of the present disclosure, so it will not be described in detail.
[0043] In an embodiment of the present application, the detection module 30 is disposed on the bottom surface of the experiment tank 11 and is signal connected to the chip set 20. The detection module 30 is a chip with a gas property measuring function, which is used to measure at least one gas property of the experiment waste gas 910, such as pH, pressure, density, humidity, and the like. The staff can directly place the container containing the experiment liquid 900 on the detection module 30 for close detection by the detection module 30. By the gas property measuring function of the detection module 30, the gas state in the experiment tank 11 can be confirmed. For example, if the experiment waste gas 910 is an acidic gas (such as hydrogen sulfide), the detection module 30 can determine whether the acidic experiment waste gas 910 remains in the experiment tank 11 or has been extracted to the outside by detecting whether the pH is normal. If the detection module 30 detects that the gas state in the experiment tank 11 is still acidic, it indicates that the acidic experiment waste gas 910 remains in the experiment tank 11, and the detection module 30 can send an air extraction instruction signal to the air extraction pump 13 to continue air extraction to completely remove the experiment waste gas 910 in the experiment tank 11. However, the gas properties that can be measured by the detection module 30 are not limited to the above, and can be changed according to actual needs.
[0044] In an embodiment of the present application, the wireless module 40, for example, is a network chip, which is disposed in the experiment tank 11 of the fume hood 10 and is signal connected to the chip set 20, the detection module 30, and the external computer 200. The wireless module 40 is used to transmit the information measured by the chip set 20 and the detection module 30 to the external computer 200, so that the staff can operate the external computer 200 to understand the data of the experiment liquid 900 contained in the intelligent fume hood 1, such as the source and flow path of the experiment liquid 900, and the gas property of the experiment waste gas 910.
[0045] In an embodiment of the present application, the battery 50 is disposed in the experiment tank 11 of the fume hood 10 and provides power to the chip set 20, the detection module 30, the wireless module 40, and the screen 60, to ensure that the chip set 20, the detection module 30, and the wireless module 40 can normally operate.
[0046] In an embodiment of the present application, the screen 60 is disposed on the wall surface of the experiment tank 11 of the fume hood 10, and the screen 60 is signal connected to the chip set 20, the detection module 30, and the battery 50. The screen 60 is used to display the information processed and detected by the chip set 20 and the detection module 30, so that the staff can see the information processed and detected by the chip set 20 and the detection module 30 by looking up at the screen 60 on the wall surface of the experiment tank 11 when using the intelligent fume hood 1 to do experiments.
[0047] As Figure 1 and Figure 2As shown, when the worker uses the intelligent fume hood 1 to conduct experiments on the experimental liquid 900, the worker can pour the experimental liquid 900 into a beaker or test tube and place it on the experimental tank 11. The detection module 30 measures the gas properties of the experimental exhaust gas 910 in the experimental tank 11, such as pH, pressure, density, humidity, etc. By detecting the gas properties through the detection module 30, it can be determined whether the experimental exhaust gas 910 still remains in the experimental tank 11 or has been extracted to the outside. The worker can cover the experimental tank 11 with the movable door 12 to seal the fume hood 10 and isolate the experimental exhaust gas 910 from the outside to prevent the experimental exhaust gas 910 from spreading and causing pollution.
[0048] In addition, the positioning member 22 is used to position the intelligent fume hood 1 to determine the current position of the intelligent fume hood 1. The temperature detection member 23 is a chip with temperature sensing function to detect the temperature of the intelligent fume hood 1, so that the temperature of the intelligent fume hood 1 can be monitored to avoid the influence of overheating or overcooling environment on the quality of the experimental liquid 900.
[0049] In addition, the worker can also operate the external computer 200 to connect to the wireless module 40 of the intelligent fume hood 1 to input information of the electronic tag member 24, such as the manufacturing date of the intelligent fume hood 1, the date and place of cultivating the experimental liquid 900 using the intelligent fume hood 1, the type of the experimental liquid 900, etc. Therefore, the information of the intelligent fume hood 1 and the experimental liquid 900 can be recorded in the electronic tag member 24, and the worker can use the electronic tag reader 300 to read the data recorded in the electronic tag member 24 to quickly understand the relevant information of the intelligent fume hood 1 and the experimental liquid 900.
[0050] In addition, the worker can also operate the external computer 200 to input the source and circulation history of the experimental liquid 900 into the blockchain information tracing member 21, and then record the source and circulation history of the experimental liquid 900 in the blockchain network 400 through the blockchain information tracing member 21. By using the function of tracing the circulation history of the blockchain, the source of the experimental liquid 900, the place where the experimental liquid 900 is obtained, the place where the experimental liquid 900 is made and stored, the process of transporting the experimental liquid 900, etc. can be recorded in the blockchain network 400. In this way, the source and circulation history of the experimental liquid 900 can be clearly recorded and managed by using the traceable and tamper-proof characteristics of the blockchain. Therefore, even if the experimental liquid 900 is found to have problems (such as contamination or deterioration), the worker can quickly trace the source and circulation history of the experimental liquid 900 through the function of tracing the circulation history of the blockchain, and confirm whether the source or circulation process of the experimental liquid 900 is wrong to cause contamination or deterioration.
[0051] By the design of the intelligent fume hood 1, the intelligent fume hood 1 has diversified and convenient multiple functions, such as tracing the source and circulation process of the experimental liquid, positioning the intelligent fume hood 1 to determine the current position of the intelligent fume hood 1, detecting the temperature of the intelligent fume hood 1 to monitor whether the intelligent fume hood 1 is at a suitable temperature, recording the experimental liquid and the intelligent fume hood 1 data by using a wireless radio frequency identification method so that the staff can quickly read the data, and measuring the gas properties of the experimental exhaust gas.
[0052] Of course, the present application can have other various embodiments, and those skilled in the art can make various corresponding changes and modifications according to the present application without departing from the spirit and essence of the present application. However, these corresponding changes and modifications should belong to the protection scope of the claims attached to the present application.
