[0034] Slots 13 are provided at both ends of the top and bottom of one side of the front end of the box body 1, and installation slots 15 are provided on the inner walls of the two slots 13. Fixed blocks 14 are slidably connected inside the two installation slots 15, and one end of the two fixed blocks 14 is fixedly connected to the pull rod 2, and springs 16 are provided on the outside of the two pull rods 2. The ends of the two plug-in blocks 8 away from the fixed seat 11 are slidably connected inside the slots 13, and the ends of the two fixed blocks 14 away from the pull rod 2 are slidably connected inside the fixed slot 10. The fixed blocks 14 fix the plug-in blocks 8 in the extended state, and the pull rod 2 is pulled to make the fixed blocks 14 withdraw from the fixed slot 10 and pull the cover plate 7 to one side to remove the plug-in blocks 8 from the slot 13, and remove the cover plate 7 from the box body 1, so that the staff can thoroughly clean the box body 1.

[0035] One end of the two springs 16 is fixedly connected to the inner wall of the installation groove 15, and the other end of the two springs 16 is fixedly connected to one end of the fixing block 14 close to the pull rod 2. After the insert block 8 is inserted into the slot 13 again, the pull rod 2 is loosened to allow the spring 16 to push the fixing block 14 into the fixing groove 10 to fix the cover plate 7 and the insert block 8.

[0036] A rubber ring 9 is fixedly connected to the rear end of the cover plate 7, a handle 6 is fixedly connected to one side of the front end of the cover plate 7, and an observation window 5 is opened in the middle of the front end of the cover plate 7. The condition of the culture dish can be observed through the observation window 5. After the cover plate 7 seals the box body 1, the rubber ring 9 can be used to seal the gap between the box body 1 and the cover plate 7. At the same time, the observation window 5 allows the staff to observe the condition of the culture dish inside the box body 1.

[0037] A display screen 4 is fixedly connected to the top of the front side of the box 1, and a plurality of evenly distributed buttons 3 are fixedly connected to one side of the front end of the box 1 close to the display screen 4. The temperature of the heating element 17 is controlled by pressing the button 3. The heating element 17 generates heat by controlling the button 3, so that the temperature inside the box 1 rises, thereby allowing the temperature to reach the temperature required by the cells inside the culture dish.

[0038] A plurality of evenly distributed grooves 12 are provided on both sides of the inner wall of the box body 1, and a plurality of trays 22 are slidably connected to the inside of the grooves 12 on both sides. Limiting grooves 21 are provided on both sides of the tops of the plurality of trays 22, and the limiting blocks 20 fix the trays 22 in the extended state. When the culture dish is placed in the box body 1, the tray 22 can be pulled out according to the height of the culture dish and placed in the corresponding groove 12, so as to adjust the height between the trays 22 to adapt to culture dishes of different heights.

[0039] A cavity 19 is formed in the inner top wall of the multiple grooves 12, and a spring 18 is fixedly connected to the inner top wall of the multiple cavities 19. The other ends of the multiple springs 18 are fixedly connected to the limiting blocks 20, and the other ends of the multiple limiting blocks 20 are slidably connected to the inside of the limiting groove 21. The tray 22 is extended into the groove 12 again and the spring 18 is used to push the limiting block 20 into the limiting groove 21 to fix the tray 22.

[0040] The rear end of the box body 1 is fixedly connected to a shell 23, and the rear end of the inner wall of the shell 23 is fixedly connected to a fan 24. The fan 24 is started to circulate air in the box body 1, and the fan 24 is started to blow air into the box body 1 to ensure the circulation of air in the box body 1.

[0041] A sensor 25 is fixedly connected to the middle of the top wall of the box body 1, and a plurality of evenly distributed heating elements 17 are fixedly connected to the inner side walls of the box body 1. The heating elements 17 can be controlled to generate heat through the button 3. At the same time, the sensor 25 can be used to detect the temperature inside the box body 1. The principles of the sensor 25 and the heating elements 17 are the same as those of the existing electric constant temperature incubator, which is a technology known to the public.

[0042] Working principle: After placing the culture dish on the top of the tray 22, hold the handle 6 and rotate the cover 7 to seal the box 1. Then, use the button 3 to control the heating element 17 to generate heat, so that the temperature inside the box 1 rises, so that the temperature can reach the temperature required by the cells inside the culture dish. At the same time, the fan 24 can be started to blow air into the box 1 to ensure the air circulation inside the box 1. When the culture dish inside the box 1 is cultured, the handle 6 can be held again to open the cover 7 to take the culture dish out of the box 1. Then, the tray 22 can be pulled to take the tray 22 out of the groove 12, so that the staff can check the tray 22. The tray 22 can be cleaned. After the cleaning is completed, the tray 22 can be extended into the groove 12 again and the spring 18 can be used to push the limit block 20 into the limit groove 21 to fix the tray 22. At the same time, the pull rod 2 can be pulled to make the fixing block 14 withdraw from the fixing groove 10 and pull the cover 7 to one side to take the plug 8 out of the slot 13, and remove the cover 7 from the box body 1, so that the staff can thoroughly clean the box body 1. After the cleaning is completed, the plug 8 can be extended into the slot 13 again, and the pull rod 2 can be released to make the spring 16 push the fixing block 14 into the fixing groove 10 to fix the cover 7 and the plug 8.
