Description

Technical Field

[0001] The invention relates to the field of microbial experimental detection equipment, in particular to a container top cover device for culturing anaerobic microorganisms. Background Art

[0002] Microorganisms are widely distributed in nature. Microbial culture refers to the process in which the laboratory uses artificially configured culture media and artificially created environments to meet the various conditions required for microbial growth, so that the microorganisms required for the experiment can grow and reproduce rapidly. Aerobic microorganisms can be cultured directly in a constant temperature incubator, and the required culture instruments are simple and easy to operate. Compared with aerobic microorganisms, anaerobic microorganisms have higher requirements for the growth environment and need to be cultured in an oxygen-free environment.

[0003] Liquid culture medium can keep cells suspended in it, so they can obtain better nutrition and growth environment. When anaerobic microorganisms are cultured in liquid, it is necessary to remove oxygen from the liquid culture medium. The current anaerobic culture technologies include anaerobic glove boxes, anaerobic tanks, dryers, anaerobic incubators and other instruments. Traditional anaerobic culture equipment is complex to operate, expensive, requires a large space for placement, has high maintenance costs, etc., and has certain limitations. There is also the problem of inconvenience in replacing culture containers when anaerobic microorganisms multiply to a certain number.

[0004] To this end, the present invention provides a container top cover device for culturing anaerobic microorganisms according to actual scientific research requirements. Summary of the invention

[0005] In view of the above situation, in order to overcome the technical defects of the existing culture devices for liquid culture of anaerobic microorganisms, the present invention provides a container top cover device for culturing anaerobic microorganisms, which effectively solves the current problems of failure of anaerobic microorganism liquid culture and inconvenience in replacing culture containers.

[0006] In order to achieve the above-mentioned purpose, the present invention provides a preferred solution, a container top cover device for culturing anaerobic microorganisms, comprising: a cover body, a knob, a groove, an air inlet pipe, and an air outlet pipe, the cover body is provided with a groove, the knob slides in the groove to the position of the air inlet pipe or the air outlet pipe, the air inlet pipe or the air outlet pipe remains unobstructed, and the air inlet or air outlet operation of the anaerobic bottle in a sealed state is achieved by sliding the knob.

[0007] The cover body includes a top cover, an extended portion of the cover body, and a cover body thread. The knob includes an outlet ventilation duct, an outlet sliding block, an inlet ventilation duct, and an outlet sliding block. The cover body continues to extend from the outside to the extended portion of the cover body. The cover body threads are evenly distributed on the extended portion of the cover body. The sealing of the anaerobic bottle is achieved by rotation. The grooves are symmetrically distributed on the top cover. The sliding block is embedded in the grooves. When the inlet ventilation duct and the outlet ventilation duct match the inlet pipe and the outlet pipe, the inlet pipe and the outlet pipe are in a connected state. When the inlet ventilation channel and the outlet ventilation channel do not match the inlet pipe and the outlet pipe, the inlet pipe and the outlet pipe are in a closed state.
