[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides, for example Figures 1-4 The experimental animal testing laboratory enzyme-labeled plate strip vacuum drying and storage box shown includes a box body 1 and a box cover 3 installed on the upper side of the box body 1;

[0027] The interior of the housing 1 is equipped with an internal frame 19;

[0028] Multiple support plates 25 are fixedly connected to the outer walls of the left and right ends of the internal frame 19, respectively, close to the left and right sides.

[0029] Each tray 25 has a drawer 9 on its upper side to provide storage space for ELISA strips. A humidity thermometer 4 is located on the upper side of the lid 3 to monitor temperature and humidity changes inside the chamber 1. An air inlet valve 5 is located on the upper side of the lid 3 to allow outside air into the chamber 1. An exhaust port 6 is located to the right of the air inlet valve 5 to connect to an external vacuum pump. Place the ELISA strips into their corresponding drawers 9, close the drawers 9, and store different types of ELISA strips in the sixteen drawers 9 according to their classification. Close the lid 3 and place the chamber inside. The lid 3 is securely fixed to the box body 1. Connect the vacuum pump to the air extraction port 6, close the air inlet valve 5, start the vacuum pump to evacuate the box body 1, observe the humidity thermometer 4, and ensure that the humidity inside the box is within the range of 10% to 15%. Then, place the vacuum-evacuated and well-sealed storage box into a refrigerator at 2 to 8 degrees Celsius for storage. When it is needed, take the storage box out of the refrigerator, open the air inlet valve 5, and let the outside air slowly enter the box body 1 to balance the air pressure inside and outside the box. After the air pressure is balanced, open the lid 3 and take out the enzyme labeling strips from the corresponding drawer 9 as needed.

[0030] Each of the drawers 9 has a heating plate layer 24 on its lower inner wall. Each of the heating plate layers 24 has a heating wire 23 inside to diffuse heat outward after power is applied. When the storage box is taken out of the refrigerator, the power is turned on and the heating wire 23 is activated to heat the enzyme-labeled strips in the drawer 9. The temperature displayed on the wet thermometer 4 is observed. When the temperature reaches the ambient temperature, the heating is stopped and the power is cut off.

[0031] like Figure 2 and Figure 4 As shown, the housing 1 is equipped with a control power supply 11 to provide power. The internal frame 19 is equipped with a power cord 22 to guide the power of the control power supply 11 to be distributed. Multiple power supply heads 21 are arranged at equal intervals from bottom to top on both ends of the power cord 22 to distribute the power. Each of the multiple heating plate layers 24 has a power terminal 20 on one side of its opposite side to be connected to the power supply head 21 and to supply power to the heating wire 23.

[0032] The power supply 11 outputs power, which is transmitted to each power supply head 21 through the power cord 22. The power supply head 21 then transmits the power to the connected power terminal 20, and finally to the heating wire 23. After the heating wire 23 is powered on, it starts to heat up and gently heats the enzyme-labeled strips in the drawer 9 to 30 to 35 degrees Celsius, so that the enzyme-labeled strips reach the same temperature as the outside temperature within 10 minutes.

[0033] like Figure 2 As shown, a wiring through hole 10 is provided inside the outer wall of the left end of the housing 1 to connect with the external power supply and the control power supply 11.

[0034] The through-hole 10 is a plug structure, and an external power source is inserted into the through-hole 10 to power the control power source 11.

[0035] like Figure 2 As shown, a storage box 12 is fixedly connected to the lower inner wall of the box 1. A desiccant 13 is placed inside the storage box 12. A mesh 14 is placed on the upper side of the storage box 12. A front cover 26 is placed on the front outer wall of the box 1 near the lower side to cover and seal the storage box 12.

[0036] When the humid air inside the chamber comes into contact with the desiccant 13, the moisture molecules are adsorbed into the pores of the desiccant 13, thereby reducing the humidity of the air inside the chamber and creating a dry storage environment for the ELISA strips. The mesh 14 plays a key role in isolation, allowing air to circulate freely and enabling the humid air inside the chamber to fully contact the desiccant 13, ensuring that the desiccant effectively absorbs moisture. When it is necessary to replace the desiccant 13, the front cover 26 can be removed, and the desiccant 13 can be taken out from the storage box 12 for replacement. After replacement, the front cover 26 is closed again.

[0037] like Figure 1 As shown, each of the multiple drawers 9 has a second handle 8 inside one end, which can drive the drawer 9 to move laterally under the action of external force. Each of the multiple second handles 8 has a note clip 7 on the upper side, which can hold the specific information note of the corresponding enzyme label strip, such as the test item, batch, expiration date, etc. Each of the multiple drawers 9 has a limiting frame 27 inside, which can limit the placement position and spacing of the enzyme label strip.

[0038] When the operator applies external force to pull the second handle 8, the drawer 9 will move laterally on the tray 25. The operator can record in detail the relevant information of the ELISA strips placed in the drawer 9 on a sticky note, such as the type, batch, expiration date, and applicable experimental type of the ELISA strips, and put the sticky note into the sticky note clip 7 for quick reference. The limiting frame 27, through its specific shape and size design, can limit the placement and spacing of the ELISA strips in the drawer 9, preventing the ELISA strips from shaking or colliding during the movement of the drawer 9, and avoiding damage to the ELISA strips due to mutual friction or impact.

[0039] like Figure 1 and Figure 3 As shown, the lower outer wall of the lid 3 has downward-opening grooves 17 at the four corners, and the upper outer wall of the body 1 has sealing strips 18 that are inserted into the grooves 17 at the four corners. The lid 3 has first handles 2 at the front, back, left and right ends, and the body 1 has fasteners 15 at the front, back, left and right ends. Each of the first handles 2 has a buckle 16 at one end to fasten with the fasteners 15 and restrict the position of the lid 3.

[0040] Lower the lid 3, aligning it with the body 1, so that the sealing strip 18 is accurately inserted into the groove 17. Ensure that the sealing strip 18 is in full contact with the groove 17 and forms a seal. Then, operate the first handle 2 at each of the four ends of the lid 3 in sequence to engage the buckles 16 with the corresponding fasteners 15 on the body 1. When it is necessary to remove the lid 3, open the buckles 16 on the first handle 2 at each of the four ends of the lid 3 in sequence to separate it from the fasteners 15.

[0041] The implementation principle of this embodiment is as follows: Place the ELISA strips into the corresponding drawers 9, close the drawers 9, and store the different types of ELISA strips in the sixteen drawers 9 according to the classification principle. Cover the box with the lid 3 and fix the lid 3 tightly to the box body 1. Connect the vacuum pump to the air extraction port 6, close the air inlet valve 5, start the vacuum pump to evacuate the box body 1, and observe the humidity thermometer 4 to ensure that the humidity inside the box is within the range of 10% to 15%. Then, place the vacuum-evacuated and well-sealed storage box into a refrigerator at 2 to 8 degrees Celsius for storage. When it is needed, take the storage box out of the refrigerator, open the air inlet valve 5 to allow outside air to slowly enter the box body 1 to balance the air pressure inside and outside the box. After the air pressure is balanced, open the lid 3 and take out the ELISA strips from the corresponding drawers 9 as needed. When taking the storage box out of the refrigerator, connect it to the power supply and start the heating wire 23 to heat the ELISA strips in the drawers 9. Observe the temperature displayed on the humidity thermometer 4. When the temperature reaches the ambient temperature, stop heating and disconnect the power supply.

[0042] 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.
