A drainage structure is provided between the support plate 10 and the placement groove 21, and the drainage structure is used to drain the condensed water discharged from the drainage hole 12 to the drainage groove 22.

[0035] By applying the technical solution of the utility model, the temperature regulating device includes a support plate 10 and a temperature regulating table 20. The condensed water on the outer wall of the PCR tube placed in the socket 11 will flow to the placement groove 21 through the drainage hole 12 under the action of gravity, and will be discharged from the temperature regulating table 20 through the drainage groove 22 under the drainage action of the drainage structure. In this way, the condensed water can be prevented from being deposited in the socket 11, and the condensed water can be prevented from being transferred along with the PCR tube when the PCR tube is transferred, thereby contaminating the workbench or other reagents. In this application, the automatic discharge of condensed water can be achieved through the arrangement of the drainage hole 12, the drainage structure and the drainage groove 22, without the need for manual wiping of the PCR tube, which is convenient for operation, and there is no need to manually clean the support plate 10, thereby reducing the manual operation cost.

[0036] Specifically in the present application, one end of the drainage groove 22 is connected to the placement groove 21, and the other end can be connected to the pipeline or collection device for collecting condensed water to complete the collection of condensed water and prevent the condensed water from flowing out and polluting the laboratory environment.

[0037] Furthermore, the extension direction of the drainage groove 22 can be set according to the collection pipeline or the collection device, and can be extended in the horizontal direction or the vertical direction, as long as it can play a role in draining the condensed water.

[0038] Furthermore, if Figure 2 As shown, the placement groove 21 has a first end 201 and a second end 202 that are relatively arranged along a preset direction, the drainage groove 22 is connected to the first end 201, and the distance from the groove bottom of the placement groove 21 to the notch of the placement groove 21 gradually increases from the second end 202 to the first end 201, and there is a drainage gap between the groove bottom of the placement groove 21 and the support plate 10. Through the above arrangement, the condensed water discharged from the drainage hole 12 can flow from the second end 202 to the first end 201 under the action of gravity, and be discharged through the drainage groove 22, so that the automatic discharge of the condensed water can be realized, and the drainage gap formed between the support plate 10 and the placement groove 21 can prevent the support plate 10 from blocking the drainage groove 22, thereby ensuring the normal flow of the condensed water.

[0041] Specifically in the present application, a support member can be set at the first end 201, one end of the support plate 10 abuts against the bottom of the placement groove 21 at the second end 202, and the other end of the support plate 10 abuts against the support member, so that after the support plate 10 is placed in the placement groove 21, a drainage gap can be formed between the support plate 10 and the placement groove 21.

[0042] Optionally, a protrusion may be provided at the bottom of the placement groove 21 near the first end 201 , and the support plate 10 is supported by the protrusion to form a drainage gap between the support plate 10 and the placement groove 21 .

With such a configuration, the water diversion grooves 13 can converge the condensed water in the plurality of drainage holes 12, so that the condensed water can be more easily gathered into a water flow and flow along the water diversion grooves 13, thereby improving the drainage effect of the drainage holes 12. Specifically, the height from the bottom of the water diversion groove 13 to the temperature control table 20 gradually decreases from the second end 202 to the first end 201. Through the above configuration, the condensed water can flow toward the first end 201 under the action of gravity, which can further improve the diversion effect of the water diversion groove 13 and make the condensed water easier to discharge.

[0044] In the present application, a confluence groove 23 is provided at the bottom of the placement groove 21 near the first end 201, and the confluence groove 23 extends in a direction perpendicular to the first end 201 to the second end 202. The confluence groove 23 is provided corresponding to the ends of the plurality of water diversion grooves 13 near the first end 201, and is connected to the drainage groove 22.
