[0019] The present invention will be further illustrated below with reference to the accompanying drawings and specific embodiments. These embodiments are implemented based on the technical solutions of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0020] like Figures 1 to 4As shown, an embodiment of the present invention provides a device for storing drug-resistant gene samples of carbapenem-resistant Enterobacteriaceae, comprising an outer box 1, with a lid 2 provided at the upper end of the outer box 1. The lid 2 is preferably hinged to the outer box 1 at the rear and removably fixed to the box 1 at the front via a snap, lock, or the like. An inner box 3 is spaced apart from the inner side of the outer box 1, and a plurality of semiconductor cooling fins 4 are embedded in the inner box 3. When in operation, the inner ends of the semiconductor cooling fins 4 cool the interior of the inner box 3, while the outer ends of the semiconductor cooling fins 4 heat the interior. The heat generated by these outer ends is carried away by air in the air duct formed between the outer box 1 and the inner box 3. A temperature sensor is provided inside the inner box 3, and a partition 5 is fixed to the upper end of the inner box 3. Both the inner box 2 and the partition 5 are preferably made of insulating material, but may also be a multi-layer board structure, i.e., insulating material is filled between the inner and outer boards. The partition 5 can seal the upper end of the inner box 3, preventing air from flowing between the interior of the inner box 3 and the outside. A plurality of through holes 6 are provided on the partition 5, and the through holes 6 can be used for inserting test tubes 7 containing drug-resistant gene samples, and the top cover of the upper end of the test tube 7 can be set on the upper side of the through hole 6. A plurality of sealing assemblies are fixed on the lower side of the partition 5. The number of sealing assemblies is the same as the number of through holes 6, and each sealing assembly is set on one side of a through hole 6. The sealing assembly includes a connecting seat 8 fixed to the lower side of the partition 5, and a cover 10 is hinged on the connecting seat 8 through a rotating shaft 9. A torsion spring 11 is provided between the cover 10 and the connecting seat 8. Specifically, one end of the torsion spring 11 is fixed relative to the connecting seat 8, and the other end thereof is fixed relative to the cover 10. When no test tube 7 is placed in the through hole 6, the cover 10 will rotate upward under the action of the torsion spring 11 and cover the lower side of the through hole 6. When it is necessary to take out one or some test tubes 7, the cover 10 can be automatically closed after the test tubes 7 are taken out, thereby preventing the cold air in the inner box 3 from flowing out through the through hole 6, ensuring that the temperature in the inner box 3 will not drop significantly. When the test tube 7 is placed, the cover 10 is pressed down by the test tube 7, thereby overcoming the elastic force of the torsion spring 11 to open the cover 10, without affecting the placement of the test tube 7. A small gap is set between the outside of the test tube 7 and the inside of the through hole. After the test tube is placed, the through hole 6 can basically be blocked. An elastic spacer 12 can also be set on the inside of the through hole 6, and the lower end of the spacer 12 is protruding from the lower surface of the partition 5. When the test tube 7 is taken out, the upper surface of the cover 10 is arranged to fit the lower end surface of the spacer 12. The spacer 12 can protect the test tube 7 on the one hand, and the elasticity of the spacer 12 can also be used to improve the sealing effect between the test tube 7 and the cover 10. The outer box 1 is provided with an air inlet and an air outlet, preferably on both sides of the outer box 1. A heat dissipation fan 13 is provided inside the air outlet. The outer box 1 is provided with a main controller 14 and a power interface 15. The semiconductor cooling plate 4, temperature sensor, heat dissipation fan 13 and power interface 15 are all connected to the main controller 14.An external power adapter plugs into power port 15 to provide the necessary power. Main controller 14 controls the operation of semiconductor cooler 4 based on the temperature feedback from the temperature sensor, thereby maintaining the temperature within inner box 3 within a set range. When main controller 14 controls the operation of semiconductor cooler 4, it also controls the rotation of cooling fan 13, thereby dissipating heat from the outer ends of semiconductor cooler 4. To improve heat exchange efficiency, cooling fins 16 are preferably fixed to the inner and outer ends of semiconductor cooler 4.

[0021] In order to prevent the test tube 7 from directly contacting the semiconductor refrigeration plate 4, a shield 17 is fixed on the inner side of the inner box 3. The shield 17 covers the outer side of the semiconductor refrigeration plate 4 and is provided with a plurality of heat dissipation holes.

[0022] In order to facilitate the fixing of the partition 5, a fixing column 18 is provided at each of the four inner corners of the outer box body 1. A threaded hole is opened at the upper end of the fixing column 18, and the partition 5 is fixed to the upper end of the fixing column 18 by multiple bolts.

[0023] It is also preferred to set a pad 19 at the bottom of the inner box 3. The pad 19 can be an pearl cotton board or a sponge board. A slot 191 is provided on the pad 19 on the lower side of the through hole 6. The lower end of the test tube 7 can be inserted into the slot 191, thereby fixing and protecting the lower end of the test tube 7.

[0024] In order to improve the sealing effect between the inner box 3 and the partition 5 , a sealing gasket 20 is preferably provided between the lower end of the partition 5 and the upper end of the inner box 3 .

[0025] To allow continued operation during sample transport, a battery 21 is preferably detachably fixedly attached to the outside of the outer box 1, and the battery 21 is connected to the main controller 14. While the power interface 15 is connected to the power adapter, the main controller 14 can control the charging of the battery 21, and the battery 21 can provide operating power during transport.

[0026] To prevent dust from entering the outer housing 1 through the air inlet, an air filter 22 can be installed inside the air inlet. Air filter 22 can be made of non-woven fabric, for example. To improve safety, a protective grid 23 can be installed outside the air outlet. Multiple legs 24 can also be fixed to the underside of the outer housing 1. The lower ends of the legs 24 are rubber blocks that protect the placement area and increase friction.

[0027] The above description is merely a preferred embodiment of the present invention. It should be noted that for those skilled in the art, any other aspects not specifically described are considered prior art or common knowledge. Improvements and modifications may be made without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention.
