[0034] The inner wall of the box body 1 is fixedly connected with slide rails 2. A plurality of slide rails 2 are evenly distributed along a straight line from top to bottom. The inner side of the slide rails 2 is slidably connected with a support plate 3. The slide rails 2 and the support plate 3 divide the inside of the box body 1 into multiple non-connected regions. The front side of the outer wall of the box body 1 is rotatably connected with a front door 4, and the left side of the outer wall of the box body 1 is rotatably connected with a side door 5;

[0035] A multi-region gas transportation mechanism 6 for transporting various gases into the inside of the box body 1 is arranged on the front door 4;

[0036] The multi-region gas transportation mechanism 6 includes a region sealing component 61 for separately sealing each region inside the box body 1, a gas input component 62 for inputting the same type of gas, and a specific gas transportation structure 63 for inputting special types of gas. The region sealing component 61 is connected to the front door 4, and both the gas input component 62 and the specific gas transportation structure 63 are arranged on the region sealing component 61;

[0037] A cavity is formed at the rear side of the box body 1, and an air replacement component 7 for discharging the waste gas in the box body 1 and a condensation component 8 for condensing water vapor are arranged in the cavity.

[0038] When the utility model is in use, open the side door 5, slidably install the support plate 3 on the slide rail 2, then close the side door 5, open the front door 4, place the culture dish on the support plate 3, and place the culture dishes on different layers of the support plate 3 according to the classification. Close the front door 4, so that the area sealing component 61 realizes gas sealing for each area. Before culturing the culture dish, introduce a cleaning gas through the gas input component 62. After the cleaning gas discharges the waste gas inside the box body 1, seal the box body 1 through the air replacement component 7. At this time, input the required gas into the box body 1 through the gas input component 62, and transport the gas to different areas through the gas input component 62 respectively. When it is necessary to introduce a special gas into a specific culture dish, connect the specific gas transport structure 63 corresponding to the specific culture dish to the external gas output end, and then input the gas into the corresponding area through the specific gas transport structure 63 to realize the separate culture of the culture dishes in different areas. Introduce water vapor into the box body 1 through the condensation component 8, and condense the water vapor in advance, reducing the amount of water vapor condensation in the box body 1, which can reduce the humidity inside the box body 1 and is conducive to the subsequent cleaning of the inside of the box body 1.

[0039] The area sealing component 61 includes a sealing strip 611 and a trapezoidal block 612. The trapezoidal block 612 is fixedly connected to the inner side of the front door 4.

[0041] The gas distribution plate 623 is connected to the external gas input pipe. The gas is evenly distributed through the gas distribution plate 623 into the porous pipes 621 in each area, and the gas flows out from the output nozzle 622 through the porous pipes 621 and enters each area respectively. While ensuring the separation of each area, the gas is input, avoiding the problem of cross - contamination of cell culture dishes caused by the gas connection between areas. Due to the installation of the one - way gas valve, gas back - flow pollution of the gas distribution plate 623 will not occur.

[0042] The specific gas transportation structure 63 is set as the input pipe 631. The outer wall of the porous pipe 621 is fixedly connected with the input pipe 631. The input pipe 631 penetrates and is fixedly connected with the front door 4, and the input end of the input pipe 631 extends to the outside of the front door 4;

[0043] When special gas needs to be input, the input pipe 631 in the corresponding area is connected to the external gas input pipe, so that special gas can be input into a specific area according to needs, which is beneficial to the cultivation of various culture dishes.

[0044] The air replacement component 7 includes a driving component 71 and an air outlet 72. The air outlet 72 is opened on the inner wall of the cavity and there are multiple air outlets 72. The driving component 71 is arranged inside the cavity;

The sealing plate 712 is fixedly connected to the output end of the cylinder 711, and the sealing plate 712 is connected with the inner wall of the cavity in a limited - sliding manner;

[0046] Before culturing the culture dish, clean gas is introduced through the porous pipe 621. After the clean gas discharges the waste gas inside the box body 1 through the air outlet 72, the cylinder 711 is controlled to drive the sealing plate 712 to move, so that the sealing plate 712 covers the air outlet 72, thus sealing the box body 1 and avoiding the pollution of the box body 1 by external air;

[0047] The condensation component 8 includes a condensation pipe 81, condensation air holes 82, heat - dissipating fins 83, a collection pipe 84 and a housing 85. The condensation pipe 81 is fixedly installed on the right side of the box body 1. A plurality of condensation pipes 81 are evenly arranged in a straight - line direction. The right side of the inner wall of the cavity is fixedly connected with the housing 85. The inner end of the condensation pipe 81 extends into the housing 85. The bottom end of the housing 85 is fixedly connected with the collection pipe 84. The discharge port of the collection pipe 84 extends to the outside of the box body 1.

[0048] The collection pipe 84 extends to the outside of the box body 1;

[0049] When steam is introduced, different condenser tubes 81 are used in different areas and steam is introduced separately. The heat dissipation fins 83 are cooled through the air ducts externally connected to the box body 1. The steam enters the box body 1 from the condenser tube 81 and passes through the condensation air holes 82. During this process, the heat dissipation fins 83 will cool the condenser tube 81 inside the casing 85. When the steam encounters the inner wall of the cooling area of the condenser tube 81 inside the casing 85, it will release heat and liquefy. Most of the condensed water will fall from the dripping tube and be discharged and collected through the collecting tube 84, and then recycled. The remaining steam enters the box body 1, which is beneficial to reducing the amount of steam liquefaction in the box body 1, can reduce the humidity inside the box body 1, and is conducive to the subsequent cleaning inside the box body 1. If steam with normal humidity is to be obtained, it is only necessary not to cool the heat dissipation fins 83.
