[0002] Food safety has always been one of the most important public concerns. Food safety testing often requires sampling, classifying, and storing food properly. Then, some samples are taken out and moved to the testing center for testing of the food's physicochemical properties and biological indicators.

[0003] Because food is rich in nutrients, it is susceptible to microbial growth and spoilage, especially at high temperatures. Furthermore, the long distances between food samples and analytical laboratories exacerbate this problem. Protein-rich foods such as meat and dairy products are particularly prone to bacterial spoilage, affecting their physicochemical and biological properties and significantly impacting analytical results. Current technologies often use ice to help cool samples, but as the ice melts during transport, the internal temperature of the storage device gradually increases, affecting the overall testing results. Therefore, a sampling and storage device for food safety testing is needed. Utility Model Content

[0017] This specific embodiment is a sampling and storage device for food safety testing, such as... Figure 1 , Figure 2 and Figure 3 As shown, the sampling and storage device for food safety testing includes a storage box 1. The top of the storage box 1 has a receiving cavity 2 and a placement slot 3. The placement slot 3 can hold receiving tapes and receiving tubes, etc. The bottom of the receiving cavity 2 has a slot 21. A retaining ring 14 for receiving tubes is snapped into the slot 21. The bottom of the retaining ring 14 is inverted T-shaped. The slot 21 includes an insertion port for the bottom of the retaining ring 14 to be inserted and a positioning slot for fixing the retaining ring 14. Through the cooperation between the detachable retaining rings 14, etc., different sizes of retaining rings 14 can be easily replaced according to the working requirements of the receiving tube during operation, improving the overall practicality of the device.

[0018] The storage box 1 has a cooling chamber at its bottom, and a cooling chip 15 is embedded in the cooling chamber. The cooling chip 15 is of model TEC1-12706, but can be used but is not limited to this model. A fan 16 is installed in the cooling chamber to assist in the heat dissipation of the cooling chip 15. A number of heat dissipation holes 18 are provided on the outer side of the storage box 1, which are equidistant from each other. Through the heat dissipation holes 18, the heat generated by the hot surface of the cooling chip 15 can be easily dissipated through the heat dissipation holes 18 under the action of the fan 16, thus avoiding heat accumulation and other problems.

[0019] By combining the separately designed storage box 1 and the cooling element 15, the food placed inside the storage box 1 can be effectively refrigerated even when there is no need for external power supply in outdoor scenarios. This ensures that a low-temperature storage environment can be maintained in the wild or in power-free scenarios, preventing sample deterioration during transportation.

[0020] An operation display screen 19 is embedded on the outer side of the storage box 1. The operation display screen 19 can be used to operate and display the temperature inside the housing cavity 2. A temperature sensor is installed inside the housing cavity 2. An auxiliary power supply battery 17 is installed inside the storage box 1. A controller for control is installed inside the storage box 1. The controller model is CARELIR32V2E000. This model can be used but is not limited to.

[0021] like Figure 1 and Figure 4 As shown, a top cover 4 is hinged to the top of the storage box 1. A snap-fit ​​groove 6 is provided on the end of the top cover 4 away from the hinge. Fixing holes 7 are symmetrically provided on both sides of the snap-fit ​​groove 6. A protruding block 8 is provided on the top of the storage box 1 away from the hinge. A fixing cavity is provided inside the protruding block 8. A fixing component 9 is installed in the fixing cavity and is fixed in conjunction with the fixing hole 7. The fixing component 9 includes a positioning pin 11 that is slidably disposed in the fixing cavity. The positioning pin 11 is engaged with the fixing hole 7. A sliding block 10 is slidably disposed on the outer side of the storage box 1. The sliding block 10 is connected and fixed to the positioning pin 11 by a connecting strip 101. A pressure spring 12 is installed in the fixing cavity to assist the positioning pin 11 in pressing down.

[0022] With the fixed component 9, the top cover 4 and the storage box 1 can be quickly opened and closed. The sliding block 10 drives the connecting belt 101 to move around the groove wheel 13, which drives the positioning pin 11 to be inserted into or separated from the fixing hole 7. The operation is convenient and efficient, suitable for on-site rapid sampling and multiple opening and closing scenarios, and should avoid situations such as the storage box 1 being opened during transportation and causing the internal containing tube to fall out and be damaged.

[0023] The protruding block 8 is symmetrically rotatably equipped with a grooved wheel 13, and the connecting belt 101 is wrapped around the outer edge of the grooved wheel 13. The grooved wheel 13 can prevent the connecting belt 101 from getting stuck when the sliding block 10 pulls the connecting belt 101.

[0024] Sealing rings 5 ​​are embedded on the side of the storage box 1 adjacent to the top cover 4. The two sealing rings 5 ​​work together to seal, which can effectively prevent external air, dust and microorganisms from entering the containment cavity 2 and reduce the risk of sample contamination.

[0025] Working principle: This food safety testing sampling and storage device achieves partitioned storage of sample containers through the receiving cavity 2 and placement slot 3 opened at the top of the storage box 1. The card slot 21 set at the bottom of the receiving cavity 2 cooperates with the carding ring 14 to stably fix the receiving tube and prevent sample leakage during transportation.

[0026] The cooling chip 15 embedded in the cooling chamber reduces the internal temperature of the storage box 1 through the semiconductor cooling principle. The fan 16 works together to dissipate heat from the cooling chip 15, ensuring stable cooling efficiency. The heat dissipation holes 18 are equidistantly arranged on the outer side of the storage box 1, which can effectively dissipate the heat generated by the cooling chip 15 when it is working.

[0027] The top cover 4 is hinged to the top of the storage box 1. When closed, its locking groove 6 engages with the protruding block 8 on the top of the storage box 1. The positioning pin 11 in the fixing assembly 9 is inserted into the fixing hole 7 under the action of the top pressure spring 12, so as to achieve a stable closure of the top cover 4. When disassembling, the sliding block 10 drives the positioning pin 11 to move through the groove wheel 13 via the connecting belt 101, so as to quickly complete the opening and closing operation of the top cover 4.

[0028] The sealing rings 5 ​​are respectively set on the adjacent sides of the storage box 1 and the top cover 4. When closed, the two sealing rings 5 ​​fit tightly to form a sealing structure, effectively preventing external air and pollutants from entering the receiving cavity 2.

[0029] The operation display screen 19 is embedded on the outer side of the storage box 1 and can display parameters such as cooling temperature and battery power in real time. The battery 17 provides independent power to the cooling chip 15, fan 16 and operation display screen 19 to ensure continuous use of the device in the absence of external power.

[0030] All technical features in this embodiment can be freely combined according to actual needs.
