Description

Technical Field

[0001] This utility model relates to the technical field of standard substance storage equipment, and in particular to a constant temperature and humidity storage device for standard substances used in food testing. Background Technology

[0002] In the field of food testing, reference materials (RTCs) are substances or materials with one or more sufficiently homogeneous and stable properties that have been well-defined and can be used for instrument calibration, evaluation of measurement methods, or assignment of values ​​to other substances. RTCs are important tools for quality control and quality assurance in food testing, ensuring the accuracy, reliability, and comparability of test results.

[0003] Currently used food testing reference materials all require specific storage environments. For example, heavy metal standard solutions, used to detect excessive heavy metals in food, are typically stored refrigerated in conventional refrigerators at set temperatures. However, when the refrigerator doors are opened, the heavy metal standard solutions or other coexisting reference materials are exposed, allowing hot air to rush in and causing the internal low-temperature environment to dissipate, leading to temperature imbalances and potential deterioration or degradation of some solutions. This is especially problematic in laboratories where frequent opening of refrigerators for material retrieval further disrupts the internal low-temperature storage environment. Furthermore, mixing different reference materials can cause cross-contamination or confusion during retrieval. While some drawer-type refrigerators exist, their limited quantity makes detailed categorization and storage impossible, resulting in inefficient space utilization. Therefore, a temperature- and humidity-controlled storage device for reference materials that combines zoned isolation, rapid retrieval, and minimizes environmental interference is needed.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this utility model, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0005] To address the problem in existing technologies where retrieving standard substances from a refrigerated cabinet can easily disrupt the low-temperature environment inside the cabinet, causing temperature imbalance and interfering with the storage of other standard substances, this invention provides a constant temperature and humidity storage device for standard substances that is convenient to access, has minimal impact on the internal environment, and avoids cross-contamination.

[0006] The present invention provides a constant temperature and humidity storage device for standard substances used in food testing, which adopts the following technical solution:

[0007] A constant temperature and humidity storage device for standard substances used in food testing includes a refrigerator. A horizontal insulation plate and a vertical insulation plate are respectively connected to the inner side of the refrigerator via horizontal and vertical slots. The horizontal and vertical insulation plates are fixed perpendicularly and cross each other, dividing the refrigerator into four equal parts. A cabinet door frame is fixedly connected to one side of each horizontal and vertical insulation plate. Multiple movable openings are provided through the side wall of the cabinet door frame. One end of each movable opening is connected to a second sealing groove on the front of the cabinet door frame, and the other end is connected to a third sealing groove on the back of the cabinet door frame. A storage box extends through the inner side of each movable opening. A first sealing plate is fixed to one end of the storage box to seal the second sealing groove, and the other end is fixed to the second sealing plate to seal the third sealing groove, forming a dynamic sealing structure during the retrieval and placement process.

[0008] Furthermore, the inner side of the refrigerator is provided with a first sealing groove that is connected to the horizontal slot and the vertical slot; the cabinet door frame is fitted into the inner side of the first sealing groove, and the contact surface is made of silicone material for easy sealing.

[0009] Furthermore, a first sealing gasket is fixedly connected to the side wall edge of the first sealing plate. The first sealing gasket is made of magnetic material and is tightly attached to the inner wall of the second sealing groove.

[0010] Furthermore, a second sealing gasket is fixed to the side wall edge of the second sealing plate. The second sealing gasket is made of magnetic material and is aligned with the third sealing groove.

[0011] Furthermore, a pull handle is fixed to one side wall of the first sealing plate for pulling the storage box outward; a label groove is provided on the side wall edge of the first sealing plate.

[0012] Furthermore, symmetrical handles are fixed to the side walls of the cabinet door frame for removing the cabinet door frame, the horizontal insulation board, and the vertical insulation board.

[0013] Furthermore, a total of sixteen movable ports are provided, corresponding to the insertion of sixteen storage boxes, and four storage boxes are located in a group, corresponding to the four spaces separated by the horizontal insulation plate and the vertical insulation plate.

[0014] Furthermore, the horizontal insulation plate, the vertical insulation plate, the first sealing plate, and the second sealing plate are all made of insulation material.

[0015] Furthermore, the bottom of the refrigerator is equipped with temperature and humidity sensors, and the data is transmitted to an external monitoring terminal in real time.

[0016] In summary, this utility model has the following beneficial technical effects:

[0017] (1) In this scheme, the standard material is stored inside the storage box. During storage, one end of the storage box is sealed to the refrigerator by the first sealing plate. When the standard material is taken out, the storage box is pulled out so that the second sealing plate at the other end of the refrigerator is sealed to ensure that only the target chamber is exposed when taking out and putting out the standard material, while other areas remain sealed. Compared with the traditional method of directly opening the cabinet door for storage and retrieval, this greatly reduces temperature fluctuations and improves the storage stability of the standard material.

[0018] (2) The insulation board set up in this scheme divides the refrigerator into four spaces for storing four types of standard substances, effectively avoiding cross-contamination. At the same time, multiple storage boxes are inserted in each space to store different batches of the same type of standard substances. With the label slot at one end of the storage box, the storage is orderly. Through label management, the problem of traditional standard substances being randomly stacked and easy to get confused is solved. Attached Figure Description

[0026] The following is in conjunction with the appendix Figure 1-6 The present invention will be described in further detail below.

[0027] Example 1: In this example, refer to Figure 1 and Figure 2As shown, specifically, a constant temperature and humidity storage device for standard substances used in food testing includes a refrigerator 1. The bottom of the refrigerator 1 is equipped with a temperature sensor and a humidity sensor, and the data is transmitted to an external monitoring terminal in real time. The specific structure and operating principle of the refrigerator 1 can refer to the refrigeration equipment in the prior art.

[0028] Reference Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, specifically, the inner side of the refrigerator 1 is connected to the horizontal insulation plate 22 and the vertical insulation plate 23 via horizontal slots 12 and vertical slots 13 respectively. The horizontal insulation plate 22 and the vertical insulation plate 23 are fixed perpendicularly and cross each other, dividing the refrigerator 1 into four parts. This does not affect the circulation of cold air inside the refrigerator 1, ensuring that all four areas are in a low-temperature environment. One side of the horizontal insulation plate 22 and the vertical insulation plate 23 is fixedly connected to the cabinet door frame 2, replacing the conventional cabinet door structure. The side wall of the cabinet door frame 2 is provided with multiple movable openings 26. One end of each movable opening 26 is connected to the second sealing groove 24 on the front of the cabinet door frame 2, and the other end... The third sealing groove 25 is connected to the back of the cabinet door frame 2; the inner side of the movable opening 26 passes through the storage box 33 for storing the same batch of standard substances. The inner wall of the storage box 33 can be additionally equipped with a humidity adjustment module (such as a silica gel desiccant box) to maintain a constant humidity environment inside the box. One end of the storage box 33 is fixed to the first sealing plate 3 to seal the second sealing groove 24, and the other end is fixed to the second sealing plate 34 to seal the third sealing groove 25, forming a dynamic sealing structure during the loading and unloading process. The horizontal insulation plate 22, the vertical insulation plate 23, the first sealing plate 3 and the second sealing plate 34 are all made of insulation material, such as polyurethane foam.

[0029] Specifically, through the above technical solution, multiple storage boxes 33 are inserted into the cabinet door frame 2. The same batch of standard materials are stored separately in the storage boxes 33. When a certain batch of standard materials is taken out, the storage box 33 is pulled outward, so that the second sealing plate 34 seals the third sealing groove 25. When the material is taken out, the refrigerator 1 is still in a sealed state. Compared with the traditional method of opening the entire cabinet door, which causes the low temperature inside the refrigerator 1 to be lost and affect the storage of other standard materials, this solution only exposes the target chamber when storing and taking out standard materials, while other areas remain sealed, which can prevent the loss of cold air and reduce temperature fluctuations by more than 80%.

[0030] Reference Figure 3 , Figure 4 and Figure 6As shown, specifically, the inner side of the refrigerator 1 is provided with a first sealing groove 11 that is connected to the horizontal slot 12 and the vertical slot 13; the cabinet door frame 2 is fitted into the inner side of the first sealing groove 11, and the contact surface is made of silicone material to facilitate sealing the first sealing groove 11; the side wall of the first sealing plate 3 is fixedly connected to the first sealing gasket 35, which is made of magnetic material and is in close contact with the inner wall of the second sealing groove 24 to seal the second sealing groove 24; the side wall of the second sealing plate 34 is fixed with the second sealing gasket 36, which is made of magnetic material and is aligned with the third sealing groove 25 to seal the third sealing groove 25 when the storage box 33 is pulled out; through the silicone contact surface and magnetic gasket, the sealing effect of the refrigerator 1 can be ensured when storing and retrieving standard substances.

[0031] Reference Figure 1 and Figure 3 As shown, specifically, a pull handle 32 is fixed to one side wall of the first sealing plate 3 for pulling the storage box 33 outward, which is convenient to operate and facilitates quick access to standard substances; handles 21 are symmetrically fixed to the side wall of the cabinet door frame 2 for removing the cabinet door frame 2, the horizontal insulation plate 22 and the vertical insulation plate 23, which facilitates the disassembly of the entire cabinet door.

[0032] Example 2: In this example, refer to Figure 1 , Figure 3 and Figure 6 As shown, specifically, the side wall of the first sealing plate 3 is provided with a label slot 31 for attaching information labels. A total of sixteen movable ports 26 are provided, corresponding to the insertion of sixteen storage boxes 33. Each group of four storage boxes 33 is located in four spaces separated by the horizontal insulation plate 22 and the vertical insulation plate 23. This solution can store four different standard substances in four independent storage spaces to avoid cross-contamination. At the same time, each independent space is provided with multiple storage boxes 33 to store different batches of the same type of standard substances, further avoiding cross-contamination. The classification is orderly, avoiding confusion when taking them out.

[0033] Working principle: A cabinet door frame 2, a horizontal insulation board 22, and a vertical insulation board 23 are inserted into the inner side of the refrigerator 1, dividing the inner space of the refrigerator 1 into four parts. Then, multiple storage boxes 33 are inserted into the inner side of the movable opening 26 on the cabinet door frame 2, so that the first sealing plate 3 at one end of the storage box 33 seals the second sealing groove 24 on the front of the cabinet door frame 2, thus sealing the refrigerator 1 in conjunction with the cabinet door frame 2. When storing or retrieving standard substances, the operator selects the appropriate storage box 33 according to the storage location and quickly pulls the first sealing plate 3 outwards, allowing... The second sealing plate 34 at the other end of the storage box 33 can seal the third sealing groove 25 on the inner wall of the cabinet door frame 2, so that the refrigerator 1 remains sealed when storing and retrieving standard materials, effectively preventing the loss of low temperature inside the refrigerator 1, keeping its internal temperature balanced, and avoiding the situation where low temperature is lost and temperature imbalance occurs after the cabinet door of traditional refrigeration equipment is opened, which affects the storage of other standard materials. At the same time, by setting up multiple storage boxes 33 in different areas, different types of standard materials and different batches of standard materials can be stored in an orderly manner, with orderly storage and avoiding cross-contamination.
