[0026] By setting the filter plate 311, the air carrying spores flowing out from the fermentation equipment body 1 can be filtered to prevent the spores from leaking and spreading due to the poor sealing of the internal container.

[0027] See also Figure 4 The ventilation mechanism 2 includes a ventilation hood 201, an air inlet slot 202, a constant temperature fin 203, an air inlet hole 204, a circulation hole 205 and a fan 206.

[0029] Working principle: when a strain fermentation device is used, in the initial state, first, a vibration shaker 106 is arranged inside the fermentation equipment body 1, and a closed cover 102 is arranged above the vibration shaker 106 and is rotatably connected to the fermentation equipment body 1 through a hinge 101, so as to close the fermentation equipment body 1 for strain fermentation operation, and a filter mechanism 3 is installed inside the ventilation mechanism 2 arranged on the back of the fermentation equipment body 1, and the inner cavity of the ventilation mechanism 2 is communicated with the fermentation equipment body 1, so as to realize air circulation in the fermentation equipment body 1 and collect leaked spores;
[0030] When it is necessary to collect the leaked spores to prevent them from spreading into the air, the working fan 206 first draws the external air into the interior of the ventilation mechanism 2 through the air inlet slot 202, and the temperature is adjusted by the constant temperature fin 203, and then the air passes through the air inlet hole 204 for constant temperature treatment.
