Description

Technical Field

[0001] This application relates to the technical field of lactic acid bacteria, and particularly relates to a sample extraction device for lactic acid bacteria fermentation. Background Art

[0002] Lactic acid bacteria are a general term for a class of bacteria that can utilize fermentable carbohydrates to produce a large amount of lactic acid. These bacteria are widely distributed in nature and have rich species diversity. Except for a very small number, most of them are essential and have important physiological functions in the human body. Lactic acid bacteria are widely present in the human intestine.

[0003] During the detection process of lactic acid bacteria fermentation, a sampler is needed for sampling. However, the existing samplers usually use manual operation to extract lactic acid bacteria fermentation broth, which is difficult to extract different lactic acid bacteria fermentation broths. The process is cumbersome when frequently extracting lactic acid bacteria fermentation broth, reducing the extraction speed of lactic acid bacteria fermentation samples. Therefore, to solve the above problems, we provide a sample extraction device for lactic acid bacteria fermentation. Summary of the Utility Model

[0022] Please refer to Figures 1-4 , this utility model provides a technical solution for a sample extraction device for lactic acid bacteria fermentation:

[0023] A sample extraction device for lactic acid bacteria fermentation includes an extraction cylinder 1. The upper surface of the extraction cylinder 1 is fixedly communicated with a power cylinder 2. A control button 15 is fixedly installed on the outer surface of the power cylinder 2. A storage battery 3 is fixedly installed on the inner top wall of the power cylinder 2. A fixed plate 4 is fixedly connected to the inner wall of the power cylinder 2. A micro electric cylinder 5 is fixedly installed on the bottom surface of the fixed plate 4. The telescopic end of the micro electric cylinder 5 is fixedly connected to a rubber plug plate 6. An extraction hole 7 is opened at the bottom end of the extraction cylinder 1. The bottom end of the extraction hole 7 is fixedly communicated with an extraction pipe 8. A collection hole 11 is opened in the inner ring of the extraction cylinder 1. The right end of the collection hole 11 is fixedly communicated with a collection pipe 12. A collector 14 is threadedly connected to the outer surface of the collection pipe 12. Through the cooperation of the micro electric cylinder 5 and the rubber plug plate 6, negative pressure can be generated inside the extraction cylinder 1, and the lactic acid bacteria fermentation broth can be extracted through an extraction hose 10. And by removing and replacing the collector 14, it will be convenient to extract and collect different lactic acid bacteria fermentation broths again.

[0024] In this embodiment, an internal thread joint 9 is threadedly connected to the outer surface of the extraction pipe 8. The bottom end of the internal thread joint 9 is fixedly communicated with an extraction hose 10. A first limiting ring 13 is fixedly connected to the outer surface of the collection pipe 12. A second limiting ring 19 is fixedly connected to the inner ring of the extraction cylinder 1. The upper surface of the second limiting ring 19 is in contact with the bottom surface of the rubber plug plate 6. The bottom surface of the first limiting ring 13 is in contact with the top end of the collector 14. Specifically, through the setting of the internal thread joint 9, the extraction hose 10 can be installed. By increasing the extraction hose 10, the extraction length of the lactic acid bacteria fermentation broth will be lengthened. By using the first limiting ring 13 and the second limiting ring 19, the rubber plug plate 6 and the collector 14 will be respectively limited and separated.

[0025] In this embodiment, a fixed seat 16 is fixedly connected to the outer surface of the collection tube 12. The left side surface of the fixed seat 16 is fixedly connected to the outer surface of the extraction cylinder 1. An annularly arranged exhaust port 17 is formed on the outer surface of the extraction cylinder 1. A handle 18 is fixedly connected to the left side surface of the extraction cylinder 1.

When the lactic acid bacteria fermentation broth is extracted into the extraction cylinder 1, it can flow into the collector 14 through the collection hole 11, thereby completing the collection of the lactic acid bacteria fermentation broth. Then, remove the collector 14 and install another collector 14, and then extract and collect different lactic acid bacteria fermentation broths again in the above manner.
