[0006] The box body is provided with a thawing inner cavity, a limiting inner frame is fixedly provided in the thawing inner cavity, a plurality of upper and lower connected testing bottle limiting cavities are provided in the limiting inner frame, six bearing external blocks are fixedly provided on the lower end surface of the thawing inner cavity, and a connecting cavity opening upward is provided in the bearing external block.

[0007] As a preferred embodiment of the utility model, a bottom connecting block that can move up and down is provided in the connecting cavity, a bottom electric heating block is fixedly provided in the bottom connecting block, the bottom electric heating block can be heated, and a load-bearing spring is fixedly connected between the lower end surface of the bottom connecting block and the lower wall of the connecting cavity.

[0008] As a preferred embodiment of the utility model, a water passage cavity connected front to back is provided in the external bracket, a stirring motor is fixed in the water passage cavity, a water stirring fan blade is rotatably provided in the water passage cavity close to one side wall of the box body, and the water stirring fan blade is dynamically connected to the stirring motor at the end face of the side away from the box body.

[0009] As a preferred embodiment of the present invention, the side wall of the thawing inner cavity is provided with a plurality of water inlet holes connected to the left and right.

[0010] As a preferred embodiment of the present invention, a handle is fixedly provided on the upper end surface of the top rotating cover.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0012] 1. In the present invention, after the present invention is placed in a water bath, the thawing warm water in the external water bath will enter the thawing inner cavity through the water inlet hole. At this time, the stirring motor is started to drive the water stirring fan blades to rotate, so that the water around the box body can continuously enter the thawing inner cavity, thereby greatly improving the water flow rate in the thawing inner cavity area, and enabling the test bottle to be thawed more quickly.

[0013] 2. In the present invention, the bottom electric heating block can be started while thawing to thaw the lower fitting surface of the test bottle together, thereby preventing the fitting surface and the upper end surface of the bottom connecting block from freezing, making it easier to remove the test bottle and significantly reducing the mortality rate of stem cells.
