Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0027] This utility model provides, for example Figure 1-6 The intelligent double-door reagent storage cabinet shown includes:
[0028] The cabinet body 100 has an electrical control box 101 fixed inside and a storage rack 102 nested therein. Several storage plates 1021 are fixedly and interlaced inside the storage rack 102. Several reagent bottles are placed on the storage plates 1021. A long cabinet door 103 and a short cabinet door 104 are hinged to one side of the cabinet body 100. One side of the long cabinet door 103 is attached to one side of the electrical control box 101, and the top of the short cabinet door 104 is attached to the bottom of the electrical control box 101. The cabinet body 100 adopts a hollow double-layer design and the inner liner is made of PP material. The dimensions of the cabinet body 100 are not less than 1900 (height) × 900 (width) × 550 (depth) mm.
[0029] The radio frequency identification (RFID) mechanism 200 includes an electronic tag and a reader. The electronic tag is affixed to the reagent bottle and stores a unique identifier of the chemical reagent inside the bottle. The reader is located inside the weighing workbench and communicates with the electronic tag via radio waves. The RFID mechanism 200 uses the ultra-high frequency band (UHF RFID), with a working frequency of 860MHz-960MHz. It has the advantages of long distance (up to 12m), high speed, and high multi-tag reading efficiency.
[0030] The filter mechanism 300 is located on the top of the cabinet body 100. The filter mechanism 300 includes a first filter 301, a filter frame 302, and a second filter 303 arranged sequentially from bottom to top. A fan 304 is installed on the filter frame 302. The top of the cabinet body 100 is provided with an opening that matches the filter mechanism 300. When the cabinet door is opened, the fan 304 starts and draws the gas inside the cabinet outward, creating a negative pressure inside the cabinet. This effectively prevents harmful gases from escaping from the cabinet door. The gas inside the cabinet is filtered twice by the first filter 301 and the second filter 303 before being drawn out, ensuring that the discharged gas is clean and harmless.
[0031] For example, see Figures 2-3 As shown, it also includes a monitoring mechanism 400, which is located inside the cabinet body 100 and electrically connected to the electrical control box 101. The monitoring mechanism 400 includes a gas sensor, a temperature sensor and a humidity sensor.
[0032] In this technical solution, it is convenient to monitor whether there are volatile organic compounds (VOCs) inside the cabinet body 100, and at the same time, it is convenient to monitor whether the temperature and humidity inside the cabinet body 100 meet the set requirements. When an abnormality is detected, each sensor transmits the abnormal information to the electrical control box 101.
[0033] For example, see Figure 6As shown, it also includes a refrigeration mechanism 500, which includes a compressor 501, a condenser 502, an expansion valve 503 and an evaporator 504 connected in sequence by pipes. The compressor 501, condenser 502 and expansion valve 503 are located between the cabinet body 100 and the storage rack 102, and the evaporator 504 is located at the bottom inner side of the storage rack 102.
[0034] In this technical solution, compressor 501 compresses the gaseous refrigerant, raising its temperature and pressure. Then, the high-temperature, high-pressure refrigerant dissipates heat and liquefies through condenser 502, releasing heat to the outside of the cabinet. Then, the pressure is reduced by expansion valve 503, causing partial vaporization and a sudden drop in temperature. The low-temperature, low-pressure refrigerant absorbs heat and evaporates through evaporator 504, lowering its surrounding temperature. This refrigeration principle is existing technology and will not be elaborated here. By setting up the refrigeration mechanism 500, the main body of the cabinet 100 has a refrigeration function, thereby extending the storage time of reagents in the main body of the cabinet 100.
[0035] For example, see Figures 1-2 As shown, it also includes an identity recognition mechanism 600, which is located on one side of the electrical control box 101. The identity recognition mechanism 600 includes four identity recognition methods: card swiping recognition, fingerprint recognition, face recognition, and password recognition.
[0036] This technical solution allows staff to easily identify themselves and open the reagent storage cabinet using multiple methods such as work cards, fingerprints, facial recognition, and passwords, thereby enabling them to complete operations such as warehousing, requisitioning, returning, and disposal.
[0037] For example, see Figures 1-2 As shown, a display screen 105 is provided on one side of the electrical control box 101, and the display screen 105 is electrically connected to the electrical control box 101.
[0038] In this technical solution, the display screen 105 can display the inventory quantity of items in the cabinet, as well as real-time alarm information such as issuance, return, scrapping, and illegal operations.
[0039] For example, see Figure 1 As shown, both the long cabinet door 103 and the short cabinet door 104 are equipped with door handles 106, and the door handles 106 are equipped with lock holes 107. The long cabinet door 103 and the short cabinet door 104 are respectively equipped with electric locks and mechanical locks.
[0040] This technical solution enables dual-person, dual-lock management, which is more stringent and prevents reagents from being taken out illegally due to improper management. When the system is powered off, the electronic lock automatically locks and closes the cabinet door, which can be opened with two physical keys.
[0041] For example, see Figures 2-3As shown, the cabinet body 100 is equipped with a backup power supply 108 inside, which is an uninterruptible power supply with a power outage recovery time of not less than one hour.
[0042] In this technical solution, the backup power supply 108 can provide an uninterrupted power supply to the reagent storage cabinet, enabling the reagent storage cabinet to maintain normal operation and protecting its software and hardware from damage.
[0043] For example, see Figures 1-2 As shown, a camera 109 is installed at the top of one side of the main body of the cabinet 100.
[0044] In this technical solution, the environment around the reagent storage cabinet can be monitored in real time via camera 109.
[0045] It should be noted that the backup power supply 108, camera 109, fan 304, monitoring mechanism 400, cooling mechanism 500 and identification mechanism 600 are all electrically connected to the electrical control box 101. The backup power supply 108 can provide uninterrupted power supply to the electrical control box 101 when the system is powered off, and the electrical control box 101 can provide power supply to the above-mentioned electrical appliances.
[0046] Working Principle: When using this intelligent double-door reagent storage cabinet, users first check the display screen 105 to find the location of the reagent to be retrieved or returned. Then, they complete identity authentication and unlock the electronic lock using any one of the following methods: card swipe, fingerprint recognition, facial recognition, or password recognition. The cabinet door is then opened with a physical key. At this point, the fan 304 starts, drawing air upwards from the cabinet and filtering it through the first filter 301 and the second filter 303 before expelling it. Users locate the desired reagent bottle and retrieve or return it. Finally, the cabinet door closes and automatically locks. This intelligent double-door reagent storage cabinet features an advanced design, compact structure, and ease of use. By staggering the multiple storage plates 1021, it avoids obstructing the view, allowing for a more complete display of the reagent bottles on the plates, facilitating observation and retrieval. The radio frequency identification (RFID) mechanism 200 uniquely assigns a code to the location information of each reagent bottle, which is displayed on the display screen 105, enabling quick location of the required reagent bottle, reducing cabinet door opening time, and significantly minimizing the risk of harmful gas leakage.
[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
