[0002] The cryogenic centrifuge is an efficient and precise separation device, mainly used in the fields of biomedicine, molecular biology, genetic engineering, etc. It separates substances of different densities by rotating the centrifuge cup at high speed and using centrifugal acceleration. The cryogenic centrifuge is equipped with a refrigeration system inside, which can keep the sample in a low temperature environment during the centrifugation process to prevent the sample from denaturing or inactivating, thereby protecting the biological activity of the sample. This refrigeration system can effectively reduce the centrifugal temperature and improve the separation effect.

[0003] After use, the existing low-temperature centrifuge needs to open the lid to allow the condensed water in the machine to evaporate naturally to avoid accumulation. The user needs to manually remove the lid and place it next to the machine. If the user forgets to open it, the condensed water will accumulate inside the centrifuge, which will increase the difficulty of cleaning the equipment and inconvenience for users. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1

[0023] See also Figures 1 to 4 A low-temperature centrifuge for biological culture includes a low-temperature centrifuge body 1, the top of the low-temperature centrifuge body 1 is movably connected with a cover 2 through a rotating shaft, a centrifuge chamber 3 is opened on one side of the top of the low-temperature centrifuge body 1, a rotor 4 is installed inside the centrifuge chamber 3, a cover plate 5 is arranged on the top of the rotor 4, a support plate 6 is sleeved on the outer side of the cover plate 5, and a ventilation mechanism is fixedly connected to one side of the support plate 6.

[0024] The ventilation mechanism comprises a connecting frame 701 , one end of which is fixedly connected to a sliding plate 702 , and both sides of the inner wall of the centrifugal chamber 3 are fixedly connected to fixed plates 703 .

[0025] The top of the fixed plate 703 is fixedly connected with a spring 704 , the top of the spring 704 is fixedly connected with the sliding plate 702 , and the top of the sliding plate 702 is fixedly connected with a transmission plate 705 .

[0026] The working principle of this embodiment is as follows: in the initial state, the cover 2 closed on the top of the low-temperature centrifuge body 1 will push the transmission plate 705 to move downward, so that the transmission plate 705 pushes the support plate 6 to move downward through the sliding plate 702 and the connecting frame 701. After the support plate 6 moves downward, it will drive the cover plate 5 to move downward and close with the rotor 4, so that the low-temperature centrifuge body 1 can be used normally. After using the low-temperature centrifuge body 1, the cover 2 is opened upward. After the cover 2 is opened upward, the transmission plate 705 is no longer restricted by the cover 2, and the spring 704 on the top of the fixed plate 703 will push the sliding plate 702 to move upward. The sliding plate 702 moves upward. After the movement, the connecting frame 701 will be driven to move upward, and the connecting frame 701 will be driven to move upward. After the support plate 6 moves upward, it will push the cover plate 5 to move upward, so that a gap is exposed between the cover plate 5 and the rotor 4. At this time, the user can directly move the cover plate 5 upward to separate it from the support plate 6, and then take out the separated items from the rotor 4, and then put the cover plate 5 back on the support plate 6. After the machine cover 2 is opened, the cover plate 5 will move upward by the elastic force of the spring 704, and a gap will be exposed between the cover plate 5 and the rotor 4. After the cover is automatically opened, the outside air can circulate between the cover plate 5 and the rotor 4, thereby allowing the condensed water to dry and evaporate.

[0027] Embodiment 2

[0028] This embodiment is an improvement made on the basis of the first embodiment. For details, please refer to Figures 1 to 4 The top of the transmission plate 705 is threadedly connected with an adjusting rod 8, and the adjusting rod 8 is in conflict with the machine cover 2.

[0029] By setting the adjusting rod 8, after rotating the adjusting rod 8, the adjusting rod 8 can move up and down on the top of the transmission plate 705, so that the transmission plate 705 can be extended upward, thereby achieving the effect of changing the length of the transmission plate 705. After the length of the transmission plate 705 is changed, the machine cover 2 presses down the transmission plate 705 to make the support plate 6 descend by different distances, which can adapt to different specifications of the rotor 4.

[0030] The first support column 9 is sleeved inside the spring 704 , and the bottom of the first support column 9 is fixedly connected to the fixing plate 703 .

[0031] The top of the first support column 9 is slidably connected to the second support column 10 , and the top of the second support column 10 is fixedly connected to the bottom of the sliding plate 702 .

[0032] By providing the first support column 9 and the second support column 10 , the first support column 9 and the second support column 10 can play a supporting role inside the spring 704 , so that the spring 704 is not easily bent or deformed.

[0033] One side of the top of the fixed plate 703 is fixedly connected to the limiting plate 11 , and the top of the limiting plate 11 penetrates to the top of the sliding plate 702 .

[0034] A stopper 12 is fixedly connected to the top of the limiting plate 11 , and one side of the stopper 12 is fixedly connected to the inner wall of the centrifugal chamber 3 .

[0035] By providing the limit plate 11 and the stopper 12, the stopper 12 can limit the maximum distance of the upward movement of the sliding plate 702, thereby preventing the sliding plate 702 from shaking up and down after the spring 704 pushes the sliding plate 702 upward.

[0036] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0037] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention.
