[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] Embodiment 1:

[0028] Reference Figure 1-4 A freezing tube thawing device comprises a shell 1, a freezing tube, and further comprises: a rotating disk 103, which is rotatably connected in the shell 1, and the freezing tube is installed in the rotating disk 103; a partition 104, which is fixedly connected in the shell 1, and the rotating disk 103 is located above the partition 104; a water pump 2, which is fixedly connected in the shell 1, and the water pump 2 is located below the partition 104; a liquid inlet pipe 201, which is fixedly connected to the liquid inlet end of the water pump 2, and the other end of the liquid inlet pipe 201 passes through the partition 104; a liquid outlet pipe 202, which is fixedly connected to the liquid outlet end of the water pump 2, and the liquid outlet end of the liquid outlet pipe 202 is located below the partition 104; a plurality of reflux pipes 104 1, are all arranged on the partition 104; multiple groups of heating tubes 3 are fixedly connected under the partition 104, the liquid inlet end of the liquid inlet tube 201 is located in the partition 104, multiple groups of reflux tubes 1041 are annularly arranged on the partition 104, and a one-way liquid outlet valve is connected in the reflux tube 1041. A bracket 101 is fixedly connected to the shell 1, and a servo motor 102 is fixedly connected to the bracket 101. The output end of the servo motor 102 passes through the bracket 101, and the output end of the servo motor 102 is fixedly connected to the rotating disk 103. The rotating disk 103 is provided with multiple groups of placement holes 1031, and the cryopreservation tubes are installed in the placement holes 1031.

[0029] When the device is in use, water is introduced into the shell 1, and the water pump 2 is started. Water is continuously introduced into the bottom of the partition 104 through the water pump 2, so that the water fills the bottom of the partition 104 and approaches the bottom of the rotating disk 103. At this time, the water injection can be stopped, and the heating tube 3 is started to increase the water temperature. At this time, the cryopreservation tube can be inserted into the placement hole 1031, and the servo motor 102 is started. At this time, the rotating disk 103 will rotate, causing the water in the shell 1 to rotate accordingly, forming a vortex flow. At this time, the cryopreservation tube has been thawed. Due to the vortex flow, the liquid near the center has a slow flow rate and does not contact the cryopreservation tube, while the surrounding areas are always in contact with the cryopreservation tube. At this time, the surrounding temperature is low and the center temperature is high. At this time, the liquid inlet pipe 201 at the center position can re-absorb the liquid with a higher temperature into the bottom of the partition 104, and after being heated by the heating tube 3 (this can reduce the energy required for heating), it flows back to the bottom of the cryopreservation tube through the reflux pipe 1041 and rotates accordingly, thereby increasing the temperature near the cryopreservation tube for easy use.

[0030] After thawing is completed, the servo motor 102 and the water pump 2 can be turned off and the cryotube can be taken out.

[0031] Embodiment 2:

[0032] Reference Figure 1-3 , a freezing tube thawing device, which is basically the same as Example 1, and further: a water-proof shell 203 is fixedly connected to the shell 1, and the water pump 2 is located in the water-proof shell 203.

[0033] By providing the water-isolating shell 203 , when the water pump 2 needs to be repaired or replaced later, the amount of water flowing out from under the partition 104 can be reduced, thereby reducing the waste of water resources.

[0034] The utility model uses the water pump 2 and the rotating disk 103 to allow hot water to continuously contact the frozen tubes when thawing the frozen tubes, thereby effectively thawing the frozen tubes.

[0035] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
