[0013] Preferably, the fixing ring is in interference fit with the air inlet.

[0014] Beneficial effects:

[0015] 1. The utility model provides a corrugated absorption bottle. By arranging a check valve at the air outlet of the corrugated absorption bottle, it is convenient to distinguish the air inlet and air outlet of the corrugated absorption bottle, and it is not easy to install them reversely. At the same time, the check valve enables the liquid in the corrugated absorption bottle to flow only in one direction, preventing the liquid from being sucked into the instrument to damage the instrument and invalidate the sample.

Detailed description of the specific implementation

[0021] The content of the present utility model can be more easily understood by referring to the following detailed description of the preferred implementation methods of the present utility model and the included embodiments. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the art to which the present invention belongs. When there is a contradiction, the definition in this specification shall prevail.

[0022] Embodiment 1:

[0023] Provided is a corrugated absorption bottle as shown in Figures 1 - 3 which includes: an integrally formed bottle body 1 and a check valve 2. An air inlet 11 is provided at one end of the bottle body 1, and an air outlet 12 is provided at the other end of the bottle body 1. The check valve 2 is fixedly installed at the air inlet 11, and the check valve 2 is used to prevent the liquid from flowing back in the bottle body 1.

[0024] The bottle body 1 includes a U-shaped tube 13, a spherical part 14 and an extension part 15. One end of the U-shaped tube 13 is communicated with the air inlet 11, the other end of the U-shaped tube 13 is communicated with the extension part 15, the spherical part 14 is at the top of the extension part 15, the spherical part 14 is communicated with the extension part 15, and the air outlet 12 is communicated with the spherical part 14.
