An insulated box is fixedly installed inside the box body, and a storage box is fixedly installed inside the insulated box. An insulated cover that cooperates with the insulated box is fixedly installed inside the lid. A refrigeration mechanism is installed inside the storage box. A moving mechanism is installed at the bottom of the box body. The refrigeration mechanism includes a storage slot, a fixing base, a filling port, a heat-conducting plate, and four fixing rods. This portable stem cell refrigerator uses liquid nitrogen or dry ice to preserve stem cells at low temperatures. It eliminates the need for a refrigeration mechanism inside the box, effectively reducing the size and weight of the refrigerator, making it easier to carry and transport. When stationary, the casters can retract into the support cylinder, which provides support for the box body, effectively improving the stability of the refrigerator when stationary and facilitating its use.

[0003] When staff handle cell collection tubes or open the cell storage box, a large amount of cold air inside the storage box will escape from the opening, causing the temperature inside the storage box to rise and affecting the cell storage effect. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where a large amount of cold air inside the preservation box will diffuse outward from the opening when the test tube for cell removal is opened. This invention proposes a temperature-controlled, sandwich-type cell preservation box.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a temperature-controlled sandwich cell preservation box, comprising a box body, a box cover on the top of the box body, a control panel on the top surface of the box body, a processor at the bottom of the control panel, a lithium battery at the bottom of the processor, heat dissipation holes on the bottom surface of the box body, a semiconductor cooling chip at the top of the heat dissipation holes, an insulation box at the top of the semiconductor cooling chip, storage slots arranged horizontally on the surface of the insulation box, a first return spring inside each storage slot, a storage rack at the top of each first return spring, an insulation cover on the top of the insulation box, a through hole arranged horizontally on the surface of the insulation cover, two slots on the inner wall surface of each through hole, a sealing cap inside each through hole, a guide groove on the top surface of each sealing cap, two locking blocks inside the sealing cap, a second return spring between each of the two locking blocks inside the sealing cap, and a lever on the top surface of each of the two locking blocks inside the sealing cap.

[0006] Preferably, the lid is hinged to the body, the control panel is mounted on the top surface of the body and screwed to the body, and the processor, lithium battery and thermoelectric cooler are all located inside the body.

[0007] Preferably, the insulated box is installed inside the box body and on the top surface of the semiconductor cooling chip, and the insulated cover is embedded in the top surface of the box body and installed on the top surface of the insulated box.

[0008] Preferably, the positions of the through holes on the surface of the heat-insulating cover correspond one-to-one with the positions of the storage slots on the surface of the heat-insulating box.

[0009] Preferably, the storage racks are all installed inside the storage slots, and the bottom surface of the storage racks is installed on the top surface of the first return spring.

[0010] Preferably, the caps are all installed in the through holes of the insulation caps, one end of each of the two locking blocks extends through the caps, and the ends of the two locking blocks extending through the caps are installed in the slots on the inner wall surface of the through holes.

[0011] Preferably, the second reset spring is installed inside the cover, the push block and the locking block are integrally formed, and one end of the push block is installed in the guide groove on the top surface of the cover.

[0012] Beneficial effects

[0013] In this invention, when the lid is opened, the cold air inside the incubator is blocked by the lid. When it is necessary to remove the test tubes containing cells, squeezing the two levers on the lid moves the two locking blocks inside the lid, causing the two locking blocks to disengage from the slots on the inner wall of the through hole on the top surface of the lid. Lifting the lid upwards releases the lid, and once released, the storage rack inside the incubator is no longer obstructed by the lid, allowing it to be ejected by the first return spring inside the storage slot. At this point, the test tubes inside the storage rack can be removed. For storage, the test tubes are placed in the storage rack, and after placement, the lid is inserted into the through hole of the incubator lid, causing the lid to press downwards for storage. The rack retracts into the insulated box. When the lid is inserted downwards, the locking blocks on both sides of the lid retract inwards. When the locking blocks of the lid move to the position of the locking groove on the inner wall of the through hole, the two locking blocks inside the lid will be squeezed out by the second return spring inside the lid, so that the locking blocks of the lid are locked into the locking groove on the inner wall of the through hole of the insulated lid to complete the fixation of the lid. Since each storage and removal only opens the lid of the corresponding area, it will not affect the lids of other areas, so that only a small amount of cold air will escape. This solves the problem that when test tubes for cell storage are opened, a large amount of cold air inside the storage box will diffuse outward from the opening of the storage box.

[0023] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1:

[0025] Reference Figure 1-6 A temperature-controlled, sandwich-type cell preservation box includes a box body 1, a box cover 2 on the top of the box body 1, a control panel 3 on the top surface of the box body 1, a processor 4 at the bottom of the control panel 3, a lithium battery 5 at the bottom of the processor 4, heat dissipation holes 7 on the bottom surface of the box body 1, a semiconductor cooling chip 6 on top of the heat dissipation holes 7, an insulation box 8 on top of the semiconductor cooling chip 6, and storage slots 9 arranged horizontally on the surface of the insulation box 8.

The surface of the insulation cover 12 has a horizontal array of through holes 13. The inner wall of each through hole 13 has two slots 14. Each through hole 13 has a cover 15 inside. The top surface of each cover 15 has a guide groove 16. Each cover 15 has two locking blocks 18 inside. A second return spring 17 is located between each of the two locking blocks 18 inside the cover 15. Each locking block 18 has a lever 19 on its top surface. The cover 2 and the box body 1 are hinged. The control panel 3 is installed on the top surface of the housing 1 and is connected to the housing 1 by screws. The processor 4, lithium battery 5, and semiconductor cooling chip 6 are all located inside the housing 1. The insulation box 8 is installed inside the housing 1 and is mounted on top of the semiconductor cooling chip 6. The insulation cover 12 is embedded in the top surface of the housing 1 and is mounted on top of the insulation box 8. The positions of the through holes 13 on the surface of the insulation cover 12 correspond one-to-one with the positions of the storage slots 9 on the surface of the insulation box 8. (Storage rack) All 11 are installed inside the storage slot 9, and the bottom surface of the storage rack 11 is installed on the top surface of the first return spring 10. All 15 are installed in the through hole 13 of the heat preservation cover 12. One end of each of the two locking blocks 18 extends through the cover 15, and the ends of the two locking blocks 18 extending through the cover 15 are installed in the locking groove 14 on the inner wall surface of the through hole 13. The second return spring 17 is installed inside the cover 15. The push block 19 is integrally formed with the locking block 18, and one end of the push block 19 is installed in the guide groove 16 on the top surface of the cover 15.

[0026] The enclosure 1 is the outer shell of the entire storage box, housing various internal components and providing protection and support. The lid 2 is connected to the enclosure 1 via hinges, allowing it to be opened and closed. When open, it facilitates user access to the internal components; when closed, it ensures a relatively sealed environment inside the insulated box 8, minimizing cold air loss. The control panel 3 serves as the user interface, providing operation buttons, a display screen, etc. Users input commands through the control panel 3, such as setting the target temperature, viewing the current internal temperature, and operating status. These commands are transmitted to the processor 4 in the form of electrical signals. The processor 4 is the "brain" of the storage box, receiving and processing the command signals from the control panel 3. Based on preset programs and algorithms, the processor 4 controls the operation of other components, such as adjusting the working state of the thermoelectric cooler 6 to maintain the internal temperature. The lithium battery 5 provides stable DC power to the entire electronic system of the storage box. When the storage box is in an environment without an external power source, the lithium battery 5 continuously outputs power to ensure the normal operation of components such as the processor 4 and the thermoelectric cooler 6. The thermoelectric cooler 6 absorbs heat on its cold side, cooling the interior of the incubator 8; it releases heat on its hot side. The generated heat is dissipated to the external environment through the heat dissipation holes 7. The processor 4 precisely controls the cooling capacity by adjusting the magnitude and direction of the current flowing through the thermoelectric cooler 6, achieving precise temperature regulation within the incubator 8. The heat dissipation holes 7 are located on the bottom surface of the chamber 1 and serve as channels for heat dissipation from the hot side of the thermoelectric cooler 6. Hot air is exhausted from the chamber through the heat dissipation holes 7, promoting air circulation, accelerating heat dissipation, and ensuring the cooling efficiency of the thermoelectric cooler 6. The incubator 8 is made of a material with good thermal insulation properties and is used to store cell samples. Its function is to reduce heat exchange between the internal cold air and the external environment, maintaining a relatively stable low-temperature environment and providing suitable conditions for cell sample preservation. Storage slots 9 are distributed on the surface of the incubator 8 and serve as mounting positions for the storage rack 11, providing guidance and support for the rack 11, enabling stable vertical movement. A first return spring 10 is installed inside the storage slot 9 and is in a compressed state. When the cap 15 disengages from the through-hole 13 of the insulation cap 12, and the obstruction to the storage rack 11 disappears, the first return spring 10 releases its elastic potential energy, pushing the storage rack 11 upwards for easy removal of the test tubes. The storage rack 11 is used to hold test tubes containing cells and can move up and down within the storage slot 9. When test tubes need to be stored, they are placed in the corresponding position on the storage rack 11; when the cap 15 is removed, it rises to a position easily accessible under the action of the first return spring 10. The insulation cap 12 is embedded in the top surface of the box 1, located above the insulation box 8, further enhancing the insulation effect. The through-holes 13 on its surface correspond one-to-one with the storage slots 9 of the insulation box 8, ensuring that the storage rack 11 can pop out and retract smoothly, and also preventing the loss of cold air when the cap 15 is installed. The through-hole 13 is the installation channel for the cap 15, and also the channel for the storage rack 11 to pop out and retract.The slot 14 on the inner wall is used to engage with the locking block 18 of the cover 15 to fix the cover 15. The slot 14 is set on the inner wall surface of the through hole 13 to lock the locking blocks 18 on both sides of the cover 15, keeping the cover 15 fixed on the insulation cover 12 and preventing it from accidentally falling off. The cover 15 is installed in the through hole 13 of the insulation cover 12 to seal the through hole 13 and reduce the loss of cold air from the corresponding area. Installation and removal are achieved through the engagement of the slot 14 and the locking block 18. The guide groove 16 is located on the top surface of the cover 15 to guide the movement of the lever 19, ensuring that the lever 19 can drive the locking block 18 to move in a predetermined direction when squeezed. The second return spring 17 is installed in the middle of the two locking blocks 18 inside the cover 15 and is in a compressed state. When the cover 15 is inserted into the through hole 13 and the locking block 18 reaches the slot 14, the second return spring 17 releases its elastic potential energy, pushing the locking block 18 outward and locking it into the slot 14, thus fixing the cover 15. The locking block 18 is connected to the second return spring 17 inside the cover 15, with one end extending through the cover 15. Driven by the lever 19, it can move inside the cover 15, achieving engagement and disengagement with the slot 14. The lever 19 and the locking block 18 are integrally formed. By squeezing the lever 19, the user moves the locking block 18 into the cover 15 under the constraint of the guide groove 16, causing the locking block 18 to disengage from the slot 14, so that the cover 15 can be removed. Specific Implementation Example 2:

[0028] Reference Figure 1-6 A temperature-controlled, sandwich-type cell preservation box is further based on the basic structure in Specific Embodiment 1. The specific process is as follows: the user sets the required temperature and other parameters through the control panel 3, and the command is transmitted to the processor 4. A lithium battery 5 powers the entire system, and a semiconductor cooling chip 6, under the control of the processor 4, performs cooling based on the Peltier effect. The cold side absorbs heat from the insulated box 8, lowering the internal temperature, while the heat from the hot side is dissipated to the outside through the heat dissipation holes 7. The insulated box 8 and the insulated cover 12 work together to reduce heat exchange and maintain a low-temperature internal environment.

[0029] When cell tubes need to be removed, open the lid 2, squeeze the lever 19 on the cap 15 to disengage the locking block 18 from the slot 14, remove the cap 15, and the storage rack 11 pops out under the action of the first return spring 10, making it easy to retrieve the test tubes. To store the test tubes, place them in the storage rack 11, insert the cap 15, and the cap 15 will press against the storage rack 11 to retract it. Simultaneously, the locking block 18 will engage with the slot 14 under the action of the second return spring 17, completing the fixation. Because only the corresponding area of ​​the cap 15 is opened at a time, the loss of cold air is greatly reduced, ensuring that cell samples are preserved in a stable low-temperature environment.

[0030] In summary:

[0031] 1. When the lid 2 is opened, the cold air inside the incubator 8 will be blocked by the incubator lid 12. When it is necessary to remove the test tubes containing cells, squeeze the two levers 19 of the cover 15 to move the two locking blocks 18 inside the cover 15, causing the two locking blocks 18 of the cover 15 to disengage from the locking grooves 14 on the inner wall of the through hole 13 on the top surface of the incubator lid 12, and lift upwards to disengage the cover 15. After the cover 15 is disengaged, the storage rack 11 inside the incubator 8 is no longer blocked by the cover 15, and the storage rack 11 is ejected by the first return spring 10 inside the storage slot 9. At this time, the test tubes inside the storage rack 11 can be taken out. When storing, install the test tubes in the storage rack 11, and after placing them, insert the cover 15 into the through hole 13 of the incubator lid 12, so that the cover 15 is pressed downwards to store them. The rack 11 is retracted into the insulated box 8. When the cover 15 is inserted downwards, the locking blocks 18 on both sides of the cover 15 retract inwards. When the locking blocks 18 of the cover 15 move to the position of the locking groove 14 on the inner wall of the through hole 13, the two locking blocks 18 inside the cover 15 will be squeezed out by the second return spring 17 inside the cover 15, so that the locking blocks 18 of the cover 15 are locked into the locking groove 14 on the inner wall of the through hole 13 of the insulated cover 12 to complete the fixation of the cover 15. Since each storage and retrieval only opens the cover 15 of the corresponding area, it will not affect the cover 15 of other areas, so that only a small amount of cold air will escape. This solves the problem that when the test tubes for cell storage are opened, a large amount of cold air inside the storage box will diffuse outward from the opening of the storage box.
