DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] Hereinafter, the embodiment of the present invention will be described in detail with reference to the drawings. It should be noted that the present invention is not limited to the following examples, and can be modified as desired without departing from the spirit and scope of the present invention.

[0017] Hereinafter, a smart fume hood according to an embodiment of the present invention will be described with reference to Figures 1 and 2. Figure 1 is a schematic diagram showing a smart fume hood according to an embodiment of the present invention. Figure 2 is a system diagram showing a smart fume hood according to an embodiment of the present invention, an external computer, an electronic tag reader, and a blockchain network.

[0018] As shown in FIG. 1 and FIG. 2, in one embodiment of the present invention, the smart fume hood 1 is used to conveniently trace the source of the experimental liquid and detect the gas properties of the experimental exhaust gas. The smart fume hood 1 is used to fill the experimental liquid 900 and extract the experimental exhaust gas 910 generated by the experimental liquid 900, and is connected to an external computer 200 and a blockchain network 400 by a signal, and transmits information related to the smart 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 chemical liquid that evaporates to generate the experimental exhaust gas 910, and the experimental liquid 900 in this embodiment is, for example, ammonia water, which evaporates to generate ammonia gas of the experimental exhaust gas 910 having a pungent odor, but the type of the experimental liquid 900 is not limited to the above and may be changed according to actual needs. The external computer 200 is, for example, a desktop computer or a laptop, and transmits data to and from the smart fume hood 1. The blockchain network 400 is an external network system that uses blockchain technology to build and store data chains.

[0019] In this embodiment, the smart fume hood 1 includes a fume hood 10, a chipset 20, a detection module 30, a wireless module 40, a battery 50, and a screen 60. The fume hood 10 is a hood body with a ventilation function, and is used for an operator to fill the experimental liquid 900 and extract the experimental exhaust gas 910 generated by the experimental liquid 900. The fume hood 10 includes an experimental water tank 11, a movable door 12, and a ventilation pump 13. The experimental water tank 11 is a container (e.g., a beaker or a test tube) for an operator to fill with the experimental liquid 900. The chipset 20, the detection module 30, the wireless module 40, the battery 50, and the screen 60 are installed in the experimental water tank 11. The detection module 30 is installed on the bottom surface of the experimental water tank 11. The movable door 12 is a transparent glass or acrylic door, and is movably connected to the experimental water tank 11. The movable door 12 is used to close the experimental tank 11 and seal the experimental tank 11 to prevent the experimental exhaust gas 910 from leaking and polluting the air. The ventilation pump 13 has a ventilation duct 131 connected to the experimental tank 11, and is electrically connected to the detection module 30 and is used to extract the experimental exhaust gas in the experimental tank 11 to an external gas filtering chamber and then discharge it to the atmosphere, filtering the experimental exhaust gas 910 to form a harmless gas, so as to prevent the experimenter from inhaling the experimental exhaust gas 910 and affecting his / her health.

[0020] In this embodiment, the chip set 20 is installed in the experimental tank 11 of the fume hood 10. The chip set 20 includes a blockchain information traceability element 21, a positioning member 22, a temperature detector 23, and an electronic tag member 24. The blockchain information traceability element 21 is a computing chip, and is connected to the blockchain network 400 by a signal, and transmits and records data to the blockchain network 400, so that the data previously recorded in the blockchain network 400 can be traced. For example, the blockchain information traceability element 21 records the source and distribution history of the experimental liquid 900 in the blockchain network 400. Due to the characteristics of the blockchain being traceable and tamper-resistant, the source and distribution history of the experimental liquid 900 are recorded and traced. The blockchain information traceability element 21 can also trace the source and distribution history of the experimental liquid 900 recorded in the blockchain network 400. According to one embodiment of the present invention, the source of the experimental liquid 900 is obtained from a chemical laboratory, a pharmaceutical factory, etc. The distribution history of the experimental liquid 900 includes the acquisition point of the experimental liquid 900, the logistics process of transporting the experimental liquid 900, the manufacturing and storage points of the experimental liquid 900, etc. In addition, the source and distribution history of the experimental liquid 900 are input to the traceability element 21 of the blockchain information by the external computer 200, and the source and distribution history of the experimental liquid 900 are recorded in the blockchain network 400 by the traceability element 21 of the blockchain information. In this way, the source and distribution history of the experimental liquid 900 are clearly recorded and managed due to the characteristics of the blockchain that are traceable and difficult to tamper with. The positioning member 22 is a GPS (Global Positioning System) chip, and the positioning member 22 is used to position the smart fume hood 1 and determine the current position of the smart fume hood 1. The temperature detector 23 is a chip with a temperature detection function and is used to detect the temperature of the smart fume hood 1.In this way, the smart fume hood 1 is monitored to ensure that the quality of the experimental solution 900 is not affected by an overheated or overcooled environment. The electronic tag member 24 records information on the smart fume hood 1 and / or the experimental solution 900 using an RFID (Radio Frequency Identification) method, such as the date of manufacture of the smart fume hood 1, the date and place when the smart fume hood 1 was used to combine the experimental solution 900, and the type of the experimental solution 900. The information recorded by the electronic tag member 24 may be input by an external computer 200. However, the information on the smart fume hood 1 is not limited to the above and can be modified according to design needs. The information recorded by the electronic tag member 24 may be read by an external electronic tag reader 300 using a wireless signal, but the electronic tag reader 300 has already been widely used in the wireless frequency technology field and is not the focus of the present invention, so a description thereof will be omitted here.

[0021] In this embodiment, the detection module 30 is installed on the bottom surface of the experimental water tank 11, and a signal is connected to the chip set 20. The detection module 30 is a chip having a function of measuring gas properties, and is used to measure at least one gas property of the experimental exhaust gas 910. The gas properties are, for example, hydrogen ion concentration, pressure, density, humidity, etc. An operator may directly place a container filled with the experimental liquid 900 on the detection module 30, so that the detection module 30 can perform short-distance detection. The function of measuring gas properties of the detection module 30 can confirm the state of the gas in the experimental water tank 11. For example, if the experimental exhaust gas 910 is an acid gas (e.g., hydrogen sulfide), the detection module 30 detects whether the hydrogen ion concentration is normal to determine whether the acidic experimental exhaust gas 910 still remains in the experimental water tank 11 or has already been extracted to the outside. If the detection module 30 detects that the gas state in the experimental tank 11 is still acidic, indicating that the acidic experimental exhaust gas 910 still remains in the experimental tank 11, the detection module 30 will send a ventilation command signal to the ventilation pump 13, so that the ventilation pump 13 will continuously ventilate to completely remove the experimental exhaust gas 910 from the experimental tank 11. However, the properties of the gas that the detection module 30 can measure are not limited to those mentioned above, and can be modified according to actual needs.

[0022] In this embodiment, the wireless module 40 is, for example, a network chip, and is installed in the experimental tank 11 of the fume hood 10, and signals are connected to the chipset 20, the detection module 30, and the external computer 200. The wireless module 40 is used to transmit information measured by the chipset 20 and the detection module 30 to the external computer 200, and an operator operates the external computer 200 to check data of the experimental liquid 900 contained in the smart fume hood 1, for example, to check the source and distribution history of the experimental liquid 900 and the gas properties of the experimental exhaust gas 910.

[0023] In this embodiment, the battery 50 is installed in the experimental aquarium 11 of the fume hood 10 and supplies power to the chipset 20, the detection module 30, the wireless module 40, and the screen 60, ensuring power for the chipset 20, the detection module 30, and the wireless module 40 to operate normally.

[0024] In this embodiment, the screen 60 is installed on the wall surface of the experimental aquarium 11 of the fume hood 10, and signals are connected to the chipset 20, the detection module 30, and the battery 50. The screen 60 is used to display messages processed and detected by the chipset 20 and the detection module 30, and when an operator uses the smart fume hood 1 to conduct an experiment, the operator can look up and see the screen 60 on the wall surface of the experimental aquarium 11 to check the messages processed and detected by the chipset 20 and the detection module 30.

[0025] As shown in Figures 1 and 2, when an operator uses the smart fume hood 1 of the present invention to conduct an experiment on the experimental liquid 900, the operator pours the experimental liquid 900 into a beaker or test tube and places it in the experimental water tank 11, and the detection module 30 measures the gas properties of the experimental exhaust gas 910 in the experimental water tank 11, such as hydrogen ion concentration, pressure, density, humidity, etc. By detecting the gas properties with the detection module 30, it can be determined whether the experimental exhaust gas 910 still remains in the experimental water tank 11 or has already been extracted to the outside. The operator closes the experimental water tank 11 with the movable door 12, sealing the fume hood 10 and isolating the experimental exhaust gas 910 from the outside, preventing the experimental exhaust gas 910 from diffusing and causing pollution.

[0026] Furthermore, positioning member 22 is used to perform positioning relative to smart fume hood 1 and determine the current position of smart fume hood 1. Temperature detector 23 is a chip with a temperature detection function, and is used to detect the temperature of smart fume hood 1. In this way, it is possible to monitor whether smart fume hood 1 is at an appropriate temperature, preventing a situation in which the quality of experimental liquid 900 is affected by an overheated or overcooled environment.

[0027] Furthermore, an operator can operate the external computer 200 to connect to the wireless module 40 of the smart fume hood 1, and input information about the smart fume hood 1 and / or the experimental liquid 900, such as the manufacturing date of the smart fume hood 1, the date and place where the experimental liquid 900 was cultured using the smart fume hood 1, and the type of experimental liquid 900, into the electronic tag member 24. In this way, information about the smart fume hood 1 and the experimental liquid 900 can be recorded in the electronic tag member 24, and then an operator can use the electronic tag reader 300 to read the data recorded in the electronic tag member 24 and quickly check information related to the smart fume hood 1 and the experimental liquid 900.

[0028] In addition, the worker operates the external computer 200 to input the source and distribution history of the experimental liquid 900 into the traceability element 21 of the blockchain information, and the traceability element 21 of the blockchain information records the source and distribution history of the experimental liquid 900 in the blockchain network 400. The source of the experimental liquid 900, the acquisition point of the experimental liquid 900, the manufacturing and storage point of the experimental liquid 900, the transportation process of the experimental liquid 900, etc. can all be recorded in the blockchain network 400 by the blockchain's item distribution history tracking function. In this way, the source and distribution history of the experimental liquid 900 are clearly recorded and managed due to the blockchain's characteristics of being traceable and recordable in a manner that is difficult to tamper with. Therefore, if a problem is detected in the experimental liquid 900 (contaminated, altered, etc.), the worker quickly traces the source and distribution history of the experimental liquid 900 using the blockchain's item distribution history tracking function, and checks whether an error has occurred in the source or distribution process of the experimental liquid 900, causing contamination or alteration.

[0029] The design of the smart fume hood 1 according to the present invention allows the smart fume hood 1 to have a variety of versatile and convenient functions, such as tracking the source and distribution history of the experimental liquid, performing positioning on the smart fume hood 1 to determine the current location of the smart fume hood 1, detecting the temperature of the smart fume hood 1 to monitor whether the smart fume hood 1 is at an appropriate temperature, recording data of the experimental liquid and the smart fume hood 1 by RFID so that the data can be quickly read by workers, measuring the gas properties of the experimental exhaust gas, etc.

[0030] The present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the claims. Embodiments obtained by appropriately combining the technical means devised in different embodiments are also included in the technical scope of the present invention. [Explanation of symbols]
