However, the bacteria culture device has the following problems in actual use:

[0004] The culture of bacterial strains has high requirements on temperature and external environmental factors. The existing bacterial strain culture devices cannot avoid external environmental factors, nor can they ensure the constancy of the internal temperature, which causes the growth environment of the bacterial community to be destroyed. On the one hand, it will affect the growth rate of the bacterial community and the efficiency of bacterial strain culture will be low. On the other hand, it may cause the mutation of the bacterial strain and cause the failure of bacterial strain culture. During the bacterial strain culture process, the bacterial strain is unevenly distributed, resulting in the existence of growth blank areas in the culture equipment, thereby reducing the growth rate of the bacterial community. The bacterial strains are divided into aerobic and anaerobic bacteria. In the closed tank, aerobic bacteria cannot get sufficient oxygen. Utility Model Content
