[0022] The L-shaped limit rods 3 are symmetrically arranged;

[0023] The L-shaped limiting rod 3 is provided with a second slot below the first slot.

[0024] When it is necessary to culture bacteria or tissues, the sterile sampled bacteria or tissues are placed in the culture fluid of the culture bottle for culture, and then the bottle cap 2 is covered, and the moving block 403 is pulled to make the limit block 401 leave the second slot, and the L-shaped limit rod 3 moves down into the limit slot, and then the moving block 403 is released. Under the action of the tensioning spring 402, the limit block 401 moves into the first slot and limits the L-shaped limit rod 3, so that the L-shaped limit rod 3 limits the bottle cap 2 to prevent the bottle cap 2 from rotating. When the bottle cap 2 needs to be removed, the moving block 403 is pulled, and the L-shaped limit rod 3 is moved up to leave the limit slot, so that the second slot matches the limit block 401, and the limit block 401 enters the second slot. The L-shaped limit rod 3 is limited and fixed inside, and then the bottle cap 2 can be rotated to take it out, and when the sterile sampled bacteria or tissues are placed in the culture medium of the culture bottle for culture, the pull rod 303 can be pulled according to the culture requirements to move the baffle 301 for sealing and ventilation adjustment, and the wrong bottle cap 2 will not be selected, and the activated carbon plate 302 can be used to adsorb and filter harmful substances in the exchange gas to avoid contamination of cells or tissues in the culture medium. Compared with the existing sterile sampling culture bottles, the bottle cap 2 is limited and fixed by the L-shaped limit rod 3, and the baffle 301 is used to realize the switching between sealed culture and breathable culture, so as to avoid contamination of the culture and effectively ensure the culture effect.

[0025] Embodiment 2:

The baffle 301 can be fixed by the close fit between the first magnetic block 304 and the second magnetic block 305 to prevent the movement of the baffle 301 from affecting the culture effect.

[0027] A sampling port is provided on the bottle cap 2, and a sealing plug 201 is arranged in the sampling port. When sampling is performed, only the sealing plug 201 needs to be pulled out to perform sampling, and there is no need to open the bottle cap 2, which makes sampling more convenient and avoids contamination of the culture solution when opening the bottle cap 2.

[0028] A plurality of bumps 101 are arranged at the lower end of the bottle body 1. The bottle body 1 is concave inward at equal intervals on the circumference to form bumps. During the bacterial culture process, when the bacteria reach a certain concentration, they will form clumps that are difficult to be shaken apart. The bumps 101 and the bumps are conducive to breaking up the bacterial clumps, so that the bacteria form uniform individuals, which is conducive to the growth of bacteria.
