[0029] Reference Figure 3Furthermore, a high-security mechanism 3 is installed inside the storage tank 102 and on the inner wall of the door 101. This high-security mechanism 3 consists of a camera 31, a storage module 32, an alarm 33, a monitoring system 34, and a door magnetic sensor 35.

By implementing this high-security mechanism, the operator's steps can be monitored in real time, ensuring the safety of food sample storage.
[0030] Specifically, when using this food testing sample storage device: First, place the device housing 1 in the designated location. The user places the storage boxes 109 for storing food samples on the surface of the pull-out plate 103. The bottom of the pull-out plate 103 moves to the surface of the support plate 104. The user affixes a label to the surface of the storage boxes 109 for easy retrieval later. The support plate 104 supports the bottom of the storage boxes 109. At this time, the storage boxes 109 move to contact the surface of the first limiting clamp 105. Under the action of the first limiting clamp 105, the storage boxes... Position 109 is limited. Then, if sterilization of the interior of the device housing 1 is required, the user removes the support plate 104 and pull-out plate 103 from the interior of the device housing 1, and installs the perforated box 106 onto the inner wall of the device housing 1 using screws. The controller 108 controls the ultraviolet germicidal lamp 107 inside the perforated box 106 to operate. Under the action of the ultraviolet germicidal lamp 107, the interior of the device housing 1 is irradiated and disinfected through the perforated box 106. After disinfection for a certain period, bacteria growth inside the device housing 1 can be effectively prevented. Afterwards, the user closes the door 101. This causes the door 101 to move, bringing the rubber pad 113 into contact with the inner wall of the device housing 1. The rubber pad 113 seals the space between the device housing 1 and the door 101. The temperature sensor 110 monitors the internal temperature of the device housing 1 and converts this information into an electrical signal, which is then transmitted to the controller 108. Upon receiving the signal from the temperature sensor 110, the controller 108 compares and calculates the signal against a preset temperature setpoint. If the internal temperature of the device housing 1 is found to be unstable, the controller 108 sends control commands to the cooler 116 and the valve 114 to activate the cooling system. The device 116 operates according to the instructions of the controller 108, adjusting the cooling capacity to achieve the set temperature target. The valve 114 adjusts its opening according to the instructions of the controller 108, controlling the flow and pressure of the fluid to ensure more precise temperature control inside the device housing 1. After the cold air inside the constant temperature chamber 117 enters the inside of the device housing 1, it cools down the temperature inside the device housing 1. When the temperature sensor 110 detects that the temperature inside the device housing 1 has reached the preset temperature set value, the controller 108 controls the valve 114 to close, so that the inside of the device housing 1 is in a constant temperature environment.
[0031] Subsequently, when the user needs to retrieve or place items from the storage box 109, the user opens the door 101 and pulls the support plate 104 inside the device box 1. This causes the support plate 104 to slide the pull-out plate 103 against the inner wall of the device box 1 and the surface of the fixed plate 111, thereby pulling the pull-out plate 103 and the support plate 104 out of the device box 1 to the desired position. Then, the user pulls the second limiting plate 112 away from the first limiting plate 105, causing the second limiting plate 112 to slide the slider 22 inside the groove 21. At this time, the slider 22 slides inside the guide groove 25. Under the combined action of the groove 21 and the guide groove 25, the slider 22 and the second limiting plate 112 are... When the slider 22 moves, it presses against the elastic element 23 on the inner wall of the groove 21, causing the elastic element 23 to contract. At this time, the slider 22 presses against the telescopic column 24 on the inner wall of the guide groove 25, causing the telescopic column 24 to also contract, thereby allowing the storage box 109 to be retrieved or placed. Subsequently, when the user releases the second limiting clamp 112, the slider 22 slides inside the groove 21 and the guide groove 25 under the elastic force of the elastic element 23 and the telescopic column 24, causing the slider 22 to drive the second limiting clamp 112 to reset, thus realizing the function of convenient retrieval and placement of the sample storage device. This makes the sample storage device more convenient for users to operate, and improves its convenience and practicality.
[0032] Subsequently, the controller 108 controls the blower 42 inside the holding box 41 to operate. Under the action of the blower 42, external air is drawn into the processing box 44. Under the action of the filter screen 43, pollutants such as dust in the air are filtered. Then, when the air passes through the activated carbon filter layer 45, the activated carbon filter layer 45 can absorb harmful substances such as formaldehyde in the air, thereby improving the air quality entering the constant temperature box 117. This prevents the samples stored in the storage box 109 from deteriorating due to contamination by foreign substances during sampling. It ensures that the air entering the device box 1 does not contain pollutants such as dust, thus realizing the anti-contamination function of the sample storage device. This allows the sample storage device to filter the air entering the device box 1 during use, which is beneficial to maintaining the integrity of the samples. At the same time, it can ensure the storage effect of the samples inside the storage box 109 and prevent the samples from deteriorating due to contamination during sampling.
[0033] Subsequently, when door 101 is opened, the door magnetic sensor 35 detects the opening status of the cabinet door. When door 101 is opened, the switch of door magnetic sensor 35 is triggered, sending a signal to monitoring system 34. After receiving the signal from door magnetic sensor 35, monitoring system 34 automatically starts shooting and transmits the captured image information to monitoring system 34. Monitoring system 34 processes the received image information and stores it inside storage module 32 for subsequent retrieval and playback. When door 101 is illegally opened or an abnormal situation occurs, alarm 33 can send alarm information to relevant personnel's mobile phones or computers via the network for timely action. The synergistic effect of these technologies ensures that camera 31 can automatically start and begin storing when door 101 is open, and automatically start storing when door 101 is closed. When closed, it will not continue to work, providing strong protection for safety and making the device housing 1 safer when storing food samples, thus achieving a high-safety function for the sample storage device. This allows for real-time monitoring of the operator's steps during use, ensuring the safety of food sample storage. The controller 108 controls the ultraviolet germicidal lamp 107, temperature sensor 110, valve 114, cooler 116, and blower 42. The specific connection and control method is existing technology. The controller 108 has sufficient processing power and interface to simultaneously monitor and control the operating status and actions of multiple electrical components, performing centralized control to ensure the efficient operation of the entire sample storage device. The specific connection and control method is existing technology and will not be elaborated here. Finally, the sample storage device is put into use.
[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
