[0019] The utility model will be further explained in detail in combination with the drawings and examples. Same parts are indicated by same reference numerals.
[0020] As Figs. 1-3 Indicated, moisture indication centrifugal tube, including pipe body 1, pipe body 1 is transparent material, and pipe body 1 is provided with containing cavity 2, and containing cavity 2 upper end is open, and containing cavity 2 is used for containing solution, and the side of pipe body 1 is provided with the detection hole 3 that communicates with containing cavity 2, specifically, detection hole 3 is close to containing cavity 2 bottom setting.
[0021] Preferably, the adjusting piece 4 is made of transparent material, and the adjusting piece 4 is movably connected to the tube body 1, so that the position of the adjusting piece 4 is adjustable relative to the tube body 1. The inner side of the adjusting piece 4 is an installation surface 5, and the installation surface 5 is attached to the outer surface of the tube body 1. The installation surface 5 is provided with an installation groove 6. The adjusting piece 4 is provided with a clamping groove corresponding to the end of the installation groove 6, and an elastic ball 7 is clamped in the clamping groove. The elastic ball 7 corresponds to the detection hole 3 and is used to block the detection hole 3. When the elastic ball 7 is separated from the detection hole 3, the containing cavity 2 and the installation groove 6 are in communication through the detection hole 3.
[0022] Preferably, the test paper 8 is arranged in the installation groove 6, and the test paper 8 is used to contact the solution in the containing cavity 2 and generate a color reaction to display the water content of the solution. The test paper 8 is any water content detection test paper in the prior art.
[0023] In the initial state, the elastic ball 7 corresponds to the detection hole 3 and blocks the detection hole 3. Further, the solution enters the containing cavity 2 and is dehydrated by the dehydration agent. After the dehydration is completed, the adjusting piece 4 is moved so that the elastic ball 7 is separated from the detection hole 3. At this time, the containing cavity 2 and the installation groove 6 are in communication, so that the solution in the containing cavity 2 can flow into the installation groove 6 in a small amount and contact the test paper 8. The test paper 8 generates a color reaction for the operator to observe the water content. When the test paper 8 shows that the water removal is completed, the adjusting piece 4 can be moved again so that the elastic ball 7 blocks the detection hole 3 again. Thus, the solution in the containing cavity 2 can be moved to other test tubes, or the tube body 1 can be used as a general test tube by blocking the detection hole 3 with the elastic ball 7.
[0024] In another detection mode, in the initial state, the elastic ball 7 is in a separated state from the detection hole 3. At this time, the containing cavity 2 and the installation groove 6 are in communication, so that the test paper 8 contacts the solution before detection, thereby achieving initial water content detection of the solution. Further, during the dehydration process, the color change on the test paper 8 can display the water content change in real time, thereby providing a basis for the operator to judge.
[0025] Preferably, the adjusting piece 4 is annular and rotates relative to the tube body 1 along the circumferential direction with the axis of the tube body 1 as the center.
[0026] The annular arrangement can reduce the difference from a general test tube, so that the tube body 1 can be directly used as a general test tube after the dehydration is completed, thereby reducing the operation process.
[0027] Preferably, the outer wall of the tube body 1 is provided with a first limiting unit, and the first limiting unit is used to abut against the adjusting piece 4 to limit the movement range of the adjusting piece 4 along the axis direction of the tube body 1.
[0028] The first limiting unit can position the adjusting piece 4, so as to ensure the correspondence between the elastic ball 7 and the detection hole 3.
[0029] Preferably, the first limiting unit comprises a limiting ring 9 sleeved on the outer wall of the pipe body 1, and the limiting ring 9 is used for abutting against the upper end of the adjusting piece 4.
[0030] The limiting ring 9 is arranged to limit the adjusting piece 4, and the limiting ring 9 is also convenient for subsequent installation of the centrifugal device.
[0031] Preferably, the outer wall of the pipe body 1 is provided with a second limiting unit, and the second limiting unit is used for limiting the rotating range of the adjusting piece 4 along the axis of the pipe body 1.
[0032] The second limiting unit is arranged to further limit the position of the adjusting piece 4, so as to ensure the position accuracy of the adjusting piece 4.
[0033] Preferably, the second limiting unit is a limiting piece 10 arranged along the axis direction of the pipe body 1, the mounting surface 5 is provided with a limiting groove 11 corresponding to the limiting piece 10, and the upper end of the limiting groove 11 is provided with an open groove 12 for the limiting piece 10 to enter the limiting groove 11.
[0034] The limiting piece 10 and the limiting groove 11 are arranged to cooperate with the annular adjusting piece 4, so as to achieve a multidirectional constraint effect, thereby ensuring the stability of the adjusting piece 4, and the open groove 12 is arranged to facilitate the connection and separation of the limiting piece 10 and the limiting groove 11, thereby facilitating the disassembly and cleaning of the adjusting piece 4 and the pipe body 1.

Any technical solution falling within the concept of the present application belongs to the protection scope of the present application.
