Air-pressure-adjustable bacteriological incubator

Abstract

The invention discloses an air-pressure-adjustable bacteriological incubator which comprises an incubator body. A lower swinging tray and an upper swinging tray are movably mounted in the incubator body, fixing grooves are formed in the upper swinging tray and the lower swinging tray, the upper swinging tray is connected with the lower swinging tray through a linkage rod, an air pressure adjusting cavity is formed in the side wall of the incubator body, the side wall of the air pressure adjusting cavity is communicated with the inside of the incubator body through a through hole, a piston is assembled in the air pressure adjusting cavity, a piston rod is connected on the piston, and one end of the piston rod penetrates the top surface of the air pressure adjusting cavity and is connected with a linear driving mechanism arranged on the side surface of the air pressure adjusting cavity. According to the bacteriological incubator, the air pressure in the incubator can be adjusted within a certain ranges according to practical experiment requirements by the aid of the air pressure adjusting cavity, so that relationships between the air pressure and bacterium growth are conveniently researched. According to the bacteriological incubator, carbon dioxide, nitrogen, oxygen, temperature and humidity can be adjusted, so that experimental research can be performed under multi-parameter conditions.

Description

technical field [0001] The invention relates to a test appliance, in particular to an air pressure adjustable bacteria incubator. Background technique [0002] Bacterial incubators are equipment used to cultivate, preserve, and test bacteria, molds, and microorganisms. They are widely used in food, biology, and other technical fields. With the continuous deepening of the current research on bacteria, the requirements for bacterial incubators are also getting higher and higher. [0003] The structure of the traditional bacterial incubator is very simple, and most of them only have the function of constant temperature regulation, or can only provide a single mode of experiment. However, the research on microorganisms needs to make the test equipment simulate the real environment of the bacteria as much as possible, so as to study the influence of different external parameters on the bacteria, but the current test chambers cannot meet this requirement. [0004] Some improved ...

AI Technical Summary

Problems solved by technology

There is no test chamber that can realize this function in the prior art, so there are many problems in the research of bacteria in this area

[0006] In addition, in the process of bacterial culture, the regular swing of the petri dish can promote mass transfer, oxygen fusion and system uniformity, but the existing incubators rarely involve this structure, or the structure is too complicated, which makes the whole incubator integrated and easy to operate. The usability is poor, and the test results are not accurate enough
