Referring to fig. 1 and 2, a test tube for food detection includes a test tube main body 1; the bottom of the test tube main body 1 is conical; a non-return structure 2 is arranged above the inner part of the test tube main body 1; a flexible sealing cover 3 is arranged at the opening end of the test tube main body 1, and an exhaust hole 4 is arranged at one end, far away from the test tube main body 1, of the flexible sealing cover 3; the bottom of test tube main part 1 is equipped with supporting seat 5.

The cuvette body 1 is a plastic conventional cuvette.

Specifically, the non-return structure 2 is a belt-shaped limiting block; the limiting blocks are arranged on the inner wall of the middle part or the upper part of the test tube main body 1, and two ends of the limiting blocks along the direction of the central line of the test tube main body 1 are respectively provided with an accommodating space 6; one side edge of the accommodating space 6 is connected to the inner wall of the test tube body 1.

The non-return structure 2 is a belt-shaped limiting block used for limiting the backflow of liquid. Specifically, the stopper sets up the upper portion at 1 inner wall of test tube main part. Constitute two accommodation space 6 with test tube main body 1 inner wall through the stopper, one of them accommodation space 6 is towards test tube main body 1's bottom, and another accommodation space 6 is towards test tube main body 1's open end.

The accommodating space 6 is connected to the inner wall of the test tube body 1.

After solid-liquid separation of a sample in the test tube main body 1, slowly inclining the test tube main body 1 when liquid needs to be poured out, wherein the limiting block is positioned in the flowing direction of the liquid; when liquid passed through the stopper, because the obstruction of stopper, liquid flowed to test tube main part 1 opening part by the both sides of stopper, at the in-process of pouring liquid, the solid can be blocked in the accommodation space 6 who is close to test tube main part 1 bottom, through this accommodation space 6 with the solid separation. When standing test tube main part 1 after liquid is poured out, liquid is arranged in the accommodation space 6 that is close to test tube main part 1 export one side, and this accommodation space 6 will regard as and hold the liquid use, makes solid-liquid separation through above-mentioned structure.

Specifically, stopper and test tube main part 1 formula structure as an organic whole.

The stopper is the same material with test tube main part 1, adopts transparent material conveniently to observe.

Specifically, the soft sealing cover 3 is wrapped at the opening end of the test tube main body 1; exhaust hole 4 with the open end interval of test tube main part 1 sets up.

The soft sealing cover 3 wraps the opening end of the test tube main body 1 to seal the inside of the test tube main body 1. The whole flexible sealing cover 3 has a certain length, and the length can be selected to be 3-5 cm. The part wrapping the test tube main body 1 is removed, the length of the part is about 4cm, the soft sealing cover 3 is squeezed by hands, then air in the soft sealing cover is extruded out through the exhaust holes 4, a negative pressure space is formed inside the test tube main body 1, and the attaching degree of the soft sealing cover 3 and the test tube main body 1 is increased.

Specifically, one side of the flexible sealing cover 3 away from the opening end of the test tube main body 1 is provided with the exhaust hole 4 protruding out of the flexible sealing cover 3; the exhaust hole 4 is a cylindrical pipeline; the exhaust hole 4 communicates the inside of the test tube body 1 with the outside.

When the tube-shaped pipeline forms a closed space in the test tube main body 1, the tube-shaped pipeline is sucked together to seal the exhaust hole 4. Ensure that the inside of the test tube main body 1 forms a negative pressure space.

Specifically, the end part of the exhaust hole 4 is provided with a one-way vent valve 7 which exhausts air in the test tube main body 1 to the outside.

In order that air may enter from the exhaust hole 4 after the exhaust hole 4 forms negative pressure, a one-way vent valve 7 is arranged at the end part of the exhaust hole 4, and the one-way vent valve 7 is of a conventional structure, belongs to the prior art and is applied in the technology.

Make the air only can be to test tube body 1 outside external atmospheric air through one-way ventilation valve 7, the unable backward flow of air.

The inside negative pressure that forms of test tube main part 1 can improve the laminating degree between soft sealed lid 3 and test tube main part 1, improves the seal. Avoid in use to appear that conventional 1 end cover of test tube main part and 1 lid of test tube main part close the leakproofness poor, influence the problem of testing result, can also detect 3 parcels of soft sealed lid on test tube main part 1 through this structure in addition, holistic seal, if the leakproofness is poor, when kick-backing appears in 3 soft sealed lids, can in time change 3 soft sealed lids.

Specifically, the supporting seats 5 are three supporting rods 8 arranged along the extension direction of the test tube main body 1; one end of each of the three support rods 8 is connected with the test tube main body 1 in a triangular shape, and the other end of each support rod is connected with a support ring 9; the support ring 9 is aligned with the axis of the cuvette body 1.

When test tube main part 1 was placed at the desktop, support ring 9 was placed on the desktop, can be with test tube main part 1 vertical placing for the bottom of test tube main part 1 is placed in to the food of sampling. When there is no test tube rack, it is more convenient to use.

Supporting by three support rods 8 can save costs compared to an annular support structure.

Specifically, a breaking groove 12 is arranged at the joint of the support rod 8 and the test tube main body 1.

When test tube main part 1 was placed on the test-tube rack, when the test-tube rack did not match with test tube main part 1's bottom, can be through breaking groove 12 with the rupture of supporting seat 5, do not influence test tube main part 1 and place on the test-tube rack. This structure makes the use scene of test tube main part 1 abundanter.

The breaking groove 12 is of a conventional structure, for example, the rod diameter of the support rod 8 at the joint of the support rod 8 and the test tube body 1 becomes thin, so that the breaking is convenient. Other conventional frangible forms may also be employed. The support bar 8 is hard plastic.

Specifically, the outer wall of the test tube body 1 is provided with a marking area 10 for identifying the test tube body 1; the outside of the marking area 10 is covered with a waterproof film 11; the periphery of the waterproof membrane 11 is provided with adhesive used for adhering the waterproof membrane 11 to the test tube main body 1.

The mark zone 10 is used for marking the sampling in the test tube main body 1, convenient subsequent taking, but in actual use, because the laboratory has the existence of liquid such as water, if be infected with at the mark zone 10, can influence the definition of the content of writing in the mark zone 10, consequently set up one deck water proof membrane 11 outside the mark zone 10, can be effectively waterproof, the conventional viscose (prior art) of convenient separation can be adopted to the viscose of water proof membrane 11 and test tube main body 1. The marking area 10 is a paper sticker and is stuck on the outer wall of the test tube main body 1.

Specifically, the waterproof membrane 11 is rectangular, three sides of the waterproof membrane 11 are adhered to the test tube body 1 after the test tube is labeled in the labeling area 10 by separating the three sides of the waterproof membrane 11 from the test tube body 1. Forming a water-resistant structure of the indicia area 10.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
