The liquid storage structure 110 receives the liquid containing the detection sample dissolved in it. The liquid storage structure 110 is a test sample solution, and the excess solution in the liquid storage structure 110 overflows the overflow plate 130 and flows into the overflow structure 120 for temporary storage; the liquid storage structure 110 serves as the main body of the reaction test. By setting the specifications of the liquid storage structure 110, on the basis of being able to meet the volume and height of the test solution, the solution exceeding the overflow plate 130 of the liquid storage structure 110 will overflow to the overflow structure 120 for temporary storage, thereby preventing liquid flooding caused by excessive solution, alleviating the technical problems existing in the prior art that the detection process has many experimental steps, the operation is difficult, the use is inconvenient, and the reaction tube is prone to excessive solution, causing liquid flooding, and affecting the accuracy of the test results.

[0033] On the basis of the above embodiments, further, in a preferred embodiment of the utility model, the reaction seat 100 includes a base 140 and a receiving groove 150; the receiving groove 150 is arranged on the base 140, and the receiving groove 150 is fixedly connected to the base 140, the receiving groove 150 can be inserted into the interior of the main tube 200, the receiving groove 150 and the main tube 200 form a reaction space, and the base 140 is sealed and connected to the end of the main tube 200.

The receiving groove 150 is inserted into the main tube 200 through the open end, and the opening of the receiving groove 150 is arranged corresponding to the conveying channel of the main tube 200. When the solution inside the main tube 200 is mixed, the solution in the main tube 200 can flow into the receiving groove 150 through the conveying channel. The liquid storage structure 110 can form a liquid storage tank with the inner wall of the receiving groove 150, and the liquid storage tank is used to quantitatively store the solution, and the height of the solution in the liquid storage tank is determined to ensure that the test strip in the liquid storage tank can complete the solution running strip detection and avoid liquid overflow.

[0036] In a preferred embodiment of the present invention, the reaction seat 100 also includes a temporary retention structure 160 and a guide structure 170; the temporary retention structure 160 is arranged corresponding to the delivery channel, and the guide structure 170 is respectively connected to the temporary retention structure 160 and the liquid storage structure 110, the temporary retention structure 160 is used to buffer and temporarily retain the solution transported by the delivery channel, and the guide structure 170 is used to introduce the solution in the temporary retention structure 160 into the liquid storage structure 110.

[0037] In this embodiment, the temporary retention structure 160 is arranged corresponding to the delivery channel, that is, the delivery channel passes through the main tube 200 and is connected with the opening of the accommodating groove 150. When the solution containing the test sample dissolved in the main tube 200 flows into the temporary retention structure 160 through the delivery channel, the temporary retention structure 160 can form a buffer for the solution, that is, the temporary retention structure 160 can temporarily retain the solution. When the delivered solution gradually increases, the solution can enter the liquid storage structure 110 along the diversion structure 170, thereby ensuring the stability of the solution flow in the liquid storage structure 110 and the diversion and diversion of the solution.

[0038] In a preferred embodiment of the present invention, the temporary retention structure 160 includes a temporary retention base, which is connected to the base 140, and the temporary retention base has a temporary retention groove on the side away from the base 140; the guide structure 170 is arranged at an angle, and the distance between the end of the guide structure 170 close to the temporary retention base and the base 140 is greater than the distance between the end of the guide structure 170 close to the liquid storage structure 110 and the base 140.

At the same time, the temporary retention structure 160 is a structure adjacent to the liquid storage structure 110. The inclined guide structure 170 can ensure that the solution will only flow into the overflow structure 120 through the overflow plate 130, thereby preventing the solution in the liquid storage structure 110 from being recoiled into the temporary retention structure 160 along with the guide structure 170, thereby ensuring the unidirectional stability of the solution flow.

[0043] In a preferred embodiment of the utility model, a sampling structure 300 is also included; the base 140 is provided with a sampling port 142 corresponding to the overflow structure 120, and the sampling structure 300 is sealedly connected to the sampling port 142.
