[0032] Reference Figure 1 , Figure 2 The biological sample storage library in this embodiment includes: a storage bin 1, a front bin 2, a transition bin 3, a defrosting mechanism, and a transportation mechanism 5.

[0033] Among them, the storage bin 1 is used to store sample boxes; the front bin 2 is connected to the storage bin 1, and a tube picking mechanism 21 is provided in the front bin 2; the transition bin 3 is connected to the front bin 2, and an access port 30 that can be connected to the outside is provided on the transition bin 3; the defrosting mechanism is used to transport cold air into the transition bin 3; the transportation mechanism 5 passes through the storage bin 1, the front bin 2, and the transition bin 3 in sequence, and the transportation mechanism 5 is used to transport the sample box out of the access port 30. In the process of storing and accessing samples, by transporting cold air into the transition bin 3, the temperature of the gas in the transition bin 3 is quickly reduced, the risk of frosting is reduced, and the service life of the biological sample storage library is increased.

[0034] In order to minimize the amount of air entering the biological sample storage library during the process of transporting the sample box out of the access port 30, the storage bin 1 in this embodiment is provided with a first channel (not shown), the front bin 2 is provided with a second channel (not shown) connected to the first channel, the transition bin 3 is provided with a third channel (not shown) connected to the second channel, and the biological sample storage library also includes a first valve (not shown) and a second valve (not shown), the first valve is used to control the connection or disconnection of the first channel and the second channel, and the second valve is used to control the connection or disconnection of the second channel and the third channel. Among them, the transportation mechanism 5 passes through the first channel, the second channel, and the third channel in sequence. According to this design, when the sample box stored in the storage bin 1 is placed on the transportation mechanism 5, the first valve is opened and the second valve is closed, so that the first channel and the second channel are connected, and the second channel and the third channel are disconnected, the sample box is transported to the front bin 2 through the transportation mechanism 5, and the test tube is selected by the tube picking mechanism 21 in the front bin 2, so that the test tubes left on the sample box to be transported all contain the target sample. Then, the second valve is opened and the first valve is closed to disconnect the first channel from the second channel, and the second channel is connected to the third channel. The sample box is transported to the transition chamber 3 through the transport mechanism 5, and cold air is transported into the transition chamber 3 through the defrosting mechanism to quickly reduce the gas temperature in the transition chamber 3 to avoid frost. Finally, the access port 30 is opened, and the sample box is transported out of the access port 30 through the transport mechanism 5.

[0035] In order to ensure the airtightness of the transition chamber 3 and reduce the amount of air entering the transition chamber 3 during the process of storing and accessing the sample box, refer to Figure 1 As shown, the biological sample storage library in this embodiment further includes a cover plate 8 rotatably mounted on the transition chamber 3 for controlling the opening and closing of the access port 30 .

[0036] Specifically, refer to Figure 3As shown, the biological sample storage in this embodiment also includes a driving motor 91 disposed in the transition chamber 3, a sliding rod 92 installed in linkage with the driving motor 91, a slider 93 disposed on the sliding rod 92, and a connecting rod 94, and the two ends of the connecting rod 94 are respectively hinged with the slider 93 and the cover plate 8. When the slider 93 moves upward, the connecting rod 94 drives the cover plate 8 to rotate around the axis so that the cover plate 8 is covered on the access port 30, and when the slider 93 moves downward, the connecting rod 94 drives the cover plate 8 to rotate around the axis so that the cover plate 8 is separated from the access port 30.

[0037] Specifically, refer to Figure 3 As shown, a first through hole 31 is provided on the side wall of the transition chamber 3 in this embodiment, and the defrosting mechanism includes a first gas source, which is connected to the first through hole 31 through a first pipe. The first gas source is a cold air source. For the convenience of maintenance, the first gas source in this embodiment is arranged outside the transition chamber 3. After the gas of the first gas source flows to the first through hole 31 through the first pipe, it flows into the transition chamber 3 to quickly cool down the gas in the transition chamber 3.

[0038] In order to facilitate the transfer of cold air to the designated end of the transition chamber 3, refer to Figure 3 As shown, the defrosting mechanism in this embodiment also includes a first air pipe 4 fixedly installed in the transition chamber 3, and the first air pipe 4 is connected to the first through hole 31 through the second pipe. Through the arrangement of the first air pipe 4, the cold air can be collected to the first air pipe 4 before flowing out. If the cold air is first guided to the vicinity of the access port 30, the air at the access port 30 can be prevented from frosting.

[0039] Preferably, in order to more evenly transmit the cold air to the transition chamber 3, refer to Figure 3 As shown, in this embodiment, two first air pipes 4 are provided and are arranged on the inner wall of the transition chamber 3 at intervals in the vertical direction, and both first air pipes 4 can be connected through the second pipe and the first through hole 31. Of course, the present application is not limited to this, and the number of first air pipes 4 can also be one or more than or equal to three.

[0040] The biological sample storage in this embodiment further includes a drying mechanism for delivering hot air to the front chamber 2. The drying mechanism delivers air into the front chamber 2 to dry out the moisture in the air in the front chamber 2.

[0041] Specifically, refer to Figure 2 , Figure 3As shown, a second through hole 20 is provided on the side wall of the forward warehouse 2 in this embodiment, and the drying mechanism includes a second air pipe 6 and a second air source connected to the second through hole 20, and the second air source is connected to the second air pipe 6 through a third pipe. Among them, the second air source is a hot air source. For the convenience of maintenance, the second air source in this embodiment is arranged outside the forward warehouse 2. After the gas of the second air source flows to the second through hole 20 through the third pipe, it flows into the forward warehouse 2 to quickly dry the moisture in the gas in the forward warehouse 2, thereby minimizing the moisture content of the gas flowing into the transition warehouse 3 after opening the second valve.

[0042] Reference Figure 3 As shown, the biological sample storage in this embodiment also includes a height sensor 7 arranged above the transport mechanism 5, and the height sensor 7 is arranged in the transition chamber 3. The height sensor 7 can limit the height of the sample box, and an early warning will be issued if the height exceeds the set height range value. Since the heights of different sample boxes are different, by limiting the height of the sample box, the storage of the sample box can be specifically managed, so that a biological sample storage can only store a specific sample box, simplifying the control system of the biological sample storage, and having high stability.

[0043] It can be seen from the above technical solutions that the utility model has the following beneficial effects:

[0044] The utility model provides a biological sample storage library. By arranging a defrosting mechanism, cold air can be transported into a transition bin during the process of storing and retrieving samples, so as to quickly lower the temperature of the gas in the transition bin, reduce the risk of frosting, and increase the service life of the biological sample storage library.
