Description

Technical Field

[0001] The utility model relates to the technical field of microorganism detection, in particular to a folding sampling and storage device. Background Art

[0002] The process of customs microorganism detection usually includes sampling, storage, and monitoring processes. For example, when sampling the surface of a tree, a scraper is generally used to scrape the surface layer, and then it is put into a culture solution, and then the liquid is sucked for quarantine inspection.

[0003] The utility model patent CN209412214U discloses a microorganism sampling device for the surface of wood, including a test tube, a dropper, and a sampling rod. The rubber head dropper is used to take liquid from the test tube. The sampling part is used to sample microorganisms from the surface of wood. The sampling part includes artificial fibers wrapped around the second end of the sampling rod. The second end of the sampling rod can be immersed in the culture solution in the test tube to culture the sampled microorganisms.

[0004] However, the above structure has the following problems: Before sampling, both the dropper and the sampling rod are in contact with the culture solution in the test tube. If microorganisms are attached to the dropper and the sampling rod before, they may have been cultured into a large number of microorganisms by the culture solution during detection, affecting the final detection result. At the same time, using a sampling part with artificial fibers for sampling has poor sampling effect on hard surfaces such as trees.

[0005] Based on this, the utility model designs a folding sampling and storage device to solve the above problems. Summary of the Utility Model

[0006] In view of the above-mentioned shortcomings of the prior art, the utility model provides a folding sampling and storage device.

[0007] To achieve the above objectives, the utility model is realized through the following technical solutions:

[0008] A folding sampling and storage device includes a test tube;

[0009] A cap for sealing the top of the test tube is threadedly connected to the upper end of the test tube;

[0010] A liquid suction component for sucking the culture solution in the test tube is installed on the cap;

[0011] A scraping component for scraping the surface of the sampling object and piercing the liquid storage component, and being in a folded state before scraping, and in an unfolded state during and after scraping is installed on the cap;

[0012] A wiping component for wiping and sampling the material for scraping the surface of the sampling object is installed on the cap (2);

[0013] Inside the test tube, a liquid storage component is installed to separate the culture medium from the liquid suction component, wiping component, and scraping component.

[0014] Furthermore, the liquid suction component includes a balloon and a straw; the lower end of the balloon is fixedly connected to the straw, the upper end of the straw is fixedly and sealingly connected to the cap, and the lower end of the straw is located inside the test tube.

[0015] Furthermore, the liquid storage component includes a curved cover and a sealing diaphragm; the upper end of the curved cover is fixedly connected to the upper cross plate, the upper cross plate is fixedly connected to the inner wall of the test tube, the lower end of the curved cover is fixedly connected to the lower cross plate, the lower cross plate is fixedly connected to the arc plate, the arc plate is fixedly connected to the inner wall of the test tube, and the sealing diaphragm is fixedly connected to the structure similar to a ring formed by the combination of the lower cross plate and the arc plate; a liquid storage space is formed between the curved cover, the sealing diaphragm and the inner wall of the test tube.

[0016] Furthermore, the liquid suction component, scraping component, and wiping component are all located above the sealing diaphragm.

[0017] Furthermore, the sealing diaphragm is fixedly connected to the lower cross plate and the arc plate by glue.

[0018] Furthermore, the wiping component includes a straight rod and a cotton ball; the top of the straight rod is fixedly connected to the inner top of the cap, and the bottom of the straight rod is fixedly connected with a cotton ball.

[0019] Furthermore, the scraping component includes a straight plate, a scraper, a horizontal axis, a stop block and a stop block; the top of the straight plate is fixedly connected to the inner top of the cap, the lower end of the straight plate is rotatably connected to the scraper through the horizontal axis, the horizontal axis is fixedly connected to the upper end of the connecting block, and a stop block for preventing the connecting block from continuing to rotate counterclockwise after rotating to the vertical state is fixedly connected to the straight plate.

[0020] Furthermore, the horizontal axis is rotatably connected to the straight plate and fixedly connected to the scraper.

[0021] Beneficial effects

[0022] The utility model forms a primary seal through the cap and a secondary seal through the sealing diaphragm. The sealing diaphragm isolates the liquid suction component, scraping component, and wiping component from the culture medium, avoiding microbial contamination; before sampling, the liquid suction component, scraping component, and wiping component of the utility model are isolated from the culture medium, preventing a large number of microorganisms from already existing in the culture medium during detection and affecting the final detection result.

[0023] When the utility model is in use, the scraping component is used to scrape the surface of the sampling object, and the wiping component is used to wipe and sample the material scraped from the surface of the sampling object. Then, the cap is covered. During this process, the scraping component pierces the sealing diaphragm. The sealing diaphragm is made of flexible material. At this time, the culture solution flows into the space where the liquid suction component, the scraping component, and the wiping component are located from the liquid storage space formed between the curved cover, the sealing diaphragm, and the inner wall of the test tube. The culture solution contacts the wiping component, and microorganisms can be cultured.

[0024] In the initial state of the utility model, the scraper is in a folded state, overlapping with the straight plate. The rotating connecting block drives the horizontal axis to rotate counterclockwise. The horizontal axis drives the scraper to rotate. After the horizontal axis rotates to the vertical state, the scraper also rotates to the vertical state, and the blade of the scraper unfolds. Then, under the blocking action of the stop block, the connecting block cannot continue to rotate. At this time, the scraper can be used to scrape the surface of the sampling object. After that, inserting the scraper into the test tube can pierce the sealing diaphragm. The present invention uses the scraping component to sample hard surfaces such as trees, with good results, and is conducive to subsequently piercing the sealing diaphragm so that the wiping component contacts the culture solution.
