DETAILED DESCRIPTION

[0019] 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.

[0020] like Figures 1 to 4As shown, a constant temperature water bath comprises a box body 1 and a constant temperature water circulation device 11. The constant temperature water circulation device 11 can circulate the water inside the box body 1. The upper part of the box body 1 is covered with a cover body 2. The constant temperature water circulation device 11 is a prior art. After the water inside the box body 1 enters the constant temperature water circulation device 11, it is heated or cooled to a set temperature value by the constant temperature water circulation device 11 and then transported into the box body 1 again to realize constant temperature water circulation.

[0021] A first support frame 13 is fixed inside the box body 1, and a plurality of storage units 4 are placed on the upper part of the first support frame 13. The plurality of storage units 4 are arranged in an upper and lower overlapped manner. The storage units 4 include a storage box 5, and a second support frame 6 is installed inside the storage box 5. A culture bottle 7 can be placed on the upper part of the second support frame 6. A liquid outlet pipe 12 is provided inside the box body 1, and water in the liquid outlet pipe 12 can flow into the storage unit 4 located at the top, and water in the storage unit 4 located at the top can flow into the storage unit 4 located below. Handles 51 are connected to both sides of the storage box 5, and a guide groove 52 is provided between the handle 51 and the side wall of the storage box 5. A liquid inlet hole 53 is provided on the side of the storage box 5, and the liquid inlet hole 53 is connected to the guide groove 52 and the inside of the storage box 5 respectively. A liquid outlet hole 54 is provided on the same side of the storage box 5 and the handle 51, and the position of the liquid outlet hole 54 is lower than the liquid inlet hole 53, so that water can enter the storage box 5 from the liquid inlet hole 53 and then flow out from the liquid outlet hole 54.

[0022] like Figures 1 to 3 As shown, after the culture bottle 7 is placed horizontally on the surface of the second support frame 6 of each storage unit 4, several storage units 4 are stacked and placed inside the box body 1. The constant temperature water circulation device 11 heats the water to 37 degrees Celsius and then flows into the guide groove 52 of the top storage unit 4 from the liquid outlet pipe 12, and flows into the storage box 5 through the liquid inlet hole 53. When the liquid level in the storage box 5 reaches the liquid level c, it flows out from the liquid outlet hole 54. The constant temperature water flowing out of the liquid outlet hole 54 then enters the guide groove 52 of the storage unit 4 located below. Finally, the constant temperature water can flow out from the liquid outlet hole 54 of the bottom storage unit 4 to the bottom of the box body 1 and circulate again through the constant temperature water circulation device 11.

[0023] The utility model can greatly increase the number of culture bottles 7 that can be placed in the box body 1 at one time by providing a multi-level storage unit 4, which is beneficial to improving the efficiency of cell harvesting. By providing a handle 51, it is not only convenient to take out the storage unit 4, but also can form a guide groove 52 between the side wall of the storage box 5 to facilitate the diversion of constant temperature water. By providing a liquid outlet 54, it can effectively ensure that the water level in each storage box 5 remains consistent.

[0024] Among them, the position of the liquid outlet 54 is higher than the upper surface of the second support frame 6 for placing the culture bottle 7, that is, the height of the liquid level c is slightly higher than the upper surface of the second support frame 6. When the culture bottle 7 is placed horizontally on the upper surface of the second support frame 6, the constant temperature water can stick to the side wall of the culture bottle 7.

[0025] The upper part of the liquid outlet pipe 12 is connected to a conversion tube 3, and the conversion tube 3 includes a connector 31 and a water outlet head 32. The connector 31 is connected to the liquid outlet pipe 12, and the water outlet head 32 is located above the guide groove 52. The conversion tube 3 is fixed to the lower part of the cover body 2. When the cover body 2 is opened, the conversion tube 3 is separated from the liquid outlet pipe 12. This design can effectively prevent interference from the conversion tube 3 when taking out the storage unit 4, and the structural design is reliable.

[0026] The storage box 5 is provided with a boss 55 on the upper part, and a groove 56 on the lower part. The boss 55 of the storage box 5 adjacent to each other and located at the lower part can be inserted into the groove 56 of the storage box 5 located at the upper part for limiting. Through the cooperation of the boss 55 and the groove 56, not only the upper and lower overlapping of the storage units 4 can be achieved, but also the upper storage unit 4 can be prevented from tipping over, thereby improving the reliability of the structure.

[0027] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
