[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model provides a human blood stem cell cooling and preservation device. The device is equipped with an opening and closing mechanism. The sliding cover opens and closes by pushing and pulling, with uniform and controllable resistance. Unlike flip-top covers, it does not require manual support to prevent tipping. The damping shaft baffle locks quickly when the cover is closed through a mechanical structure, with more uniform locking force and stronger durability. When the sliding cover is closed, it achieves a seal through planar pressing. Compared with the edge contact of flip-top covers, the sealing strip is subjected to more uniform force, reducing the risk of cold leakage. A sliding rod is provided so that the slider can slide smoothly. The cover can be pulled open to the sides by the handle, and closing it is also very simple. The locking plate and sealing strip between the covers provide a more airtight seal when closed. The damping shaft can rotate the stop block. Rotating it down against the baffle can quickly lock the cover, while rotating it up makes it easy to open the cover.

[0015] 2. This utility model provides a human blood stem cell cooling and preservation device. The device is equipped with an air-cooled circulation device. The fan accelerates the air flow inside the chamber through forced convection, breaking the limitations of natural convection and ensuring that the cold air quickly covers all areas. The hinged air guide plate guides the cold air flow to the high-temperature area in real time by automatically adjusting the angle, achieving "precise cooling". The fan promotes air flow, which can reduce local overcooling on the surface of the cooling plate and reduce the risk of frost formation. The air guide plate disperses the airflow to prevent the cold air from blowing directly to the same position, further inhibiting the formation of ice. The fan driven by the first motor can drive the airflow inside the device, promoting a more uniform distribution of cold air circulation. In addition, the first rotating rod driven by the second motor rotates clockwise or counterclockwise, causing the first air guide plate to rotate accordingly. The hinged rod enables the second air guide plate to follow the transmission, thereby adjusting the tilt angle of the air guide plate and facilitating the adjustment of the airflow direction.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] like Figure 1 and Figure 5As shown, a human hematopoietic stem cell cooling and preservation device includes an insulated box 1. An opening and closing device 2 is fixedly connected to the upper end of the insulated box 1. A sliding cover opens and closes via a push-pull action, providing uniform and controllable resistance, eliminating the need for manual support to prevent tipping, unlike a flip-top design. A damping shaft baffle quickly locks the cover when closed via a mechanical structure, providing more uniform locking force and greater durability. The sliding cover achieves a seal through planar pressing when closed, resulting in more uniform force distribution on the sealing strip compared to edge contact in a flip-top design, reducing the risk of cold leakage. A base 3 is fixedly connected to the lower end of the insulated box 1, and cooling plates 4 are fixedly connected to both sides of the inner wall of the insulated box 1. One side of the cooling plate 4... A fixed plate 5 is fixedly connected to the side, and a storage box 6 is movably connected to the upper part of the fixed plate 5. Spring buckles 7 are movably connected to both sides of the storage box 6. A wind-cooling circulation device 8 is fixedly connected to the rear of the inner wall of the insulated box 1. The fan accelerates the air flow inside the box through forced convection, breaking the limitations of natural convection and ensuring that the cold air quickly covers all areas. The hinge air guide plate guides the cold air flow to the high-temperature area in real time by automatically adjusting the angle, achieving "precise cooling". The fan promotes air flow, which can reduce local overcooling on the surface of the cooling plate and reduce the risk of frost formation. The air guide plate disperses the airflow to prevent the cold air from blowing directly to the same position, further inhibiting the formation of ice. The opening and closing device 2 includes a sliding plate 21, the lower end of which is fixedly connected to the upper end of the insulated box 1. The air-cooled circulation device 8 includes a blower box 81, which is fixedly installed on the rear part of the inner wall of the insulation box 1. A controller is fixedly connected to the front of the insulated box 1, and anti-slip feet are fixedly connected to the lower end of the base 3. A damping and shock-absorbing support is movably connected to the bottom of the storage box 6.

[0020] like Figure 2 As shown, both ends of the slide plate 21 are movably connected to the stop blocks 29. A damping shaft is provided between the slide plate 21 and the stop blocks 29. A slide rod 22 is fixedly connected to the inner wall of the slide plate 21. A slider 23 is slidably connected to the outer wall of the slide rod 22. A cover plate 24 is fixedly connected to one end of the slider 23. A handle 25 is fixedly connected to the upper end of the cover plate 24. A retaining plate 26 is fixedly connected to the adjacent ends of the two cover plates 24. A sealing strip 27 is fixedly connected to one side of the retaining plate 26. A baffle 28 is fixedly connected to one side of the cover plate 24. The slide rod 22 allows the slider 23 to slide smoothly. The cover plate 24 can be pulled open to both sides by the handle 25. Conversely, closing is also very simple. The retaining plate 26 and the sealing strip 27 provided between the cover plates 24 make the closure more airtight. The stop blocks 29 can be rotated by the damping shaft. Rotating them down and they abut against the baffle 28 can quickly lock the cover plate 24. Rotating them up makes it easy to open the cover plate 24. like Figure 3As shown, ventilation openings 82 are provided on both sides of the air box 81. A filter screen is fixedly connected to the inner wall of the ventilation opening 82. A fixing frame 83 is fixedly connected to the inner wall of the air box 81. A first motor 84 is fixedly connected to one side of the fixing frame 83. A fan 85 is fixedly connected to the output end of the first motor 84. An air guide component 86 is fixedly connected to one side of the air box 81. The fan 85 driven by the first motor 84 can drive the airflow inside the equipment and promote a more uniform distribution of cold air circulation. like Figure 4 As shown, the air guiding component 86 includes a second motor 861.

A second air guiding plate 865 is movably connected to one end of the hinge rod 864. The upper and lower ends of the second air guiding plate 865 are both fixedly connected to the second rotating rod 866. The second motor 861 drives the first rotating rod 862 to rotate clockwise or counterclockwise, causing the first air guiding plate 863 to rotate accordingly. The hinge rod 864 enables the second air guiding plate 865 to be driven accordingly, thereby adjusting the tilt angle of the air guiding plate and facilitating the adjustment of the airflow direction.

[0021] The working principle of this utility model is as follows: Through the opening and closing device 2, a sliding rod 22 is set so that the slider 23 can slide smoothly. The handle 25 can pull the cover plate 24 open to both sides, and closing it is also very simple. The cover plate 26 and sealing strip 27 are set between the cover plates 24, which makes the closure more airtight. The damping shaft can rotate the stop block 29. Rotating it down can abut against the baffle 28 to quickly lock the cover plate 24. Rotating it up makes it easy to open the cover plate 24. Using the air-cooling circulation device 8, the first motor 84 drives the fan 85 to rotate, which can drive the airflow inside the equipment and promote a more uniform distribution of cold air circulation. In addition, the second motor 861 drives the first rotating rod 862 to rotate clockwise or counterclockwise, causing the first air guide plate 863 to rotate accordingly. The hinge rod 864 enables the second air guide plate 865 to be driven, thereby adjusting the tilt angle of the air guide plate and making it easy to adjust the airflow direction.
