Refer to Figure 1-2, An integrated heating structure for sample detection includes a main frame 1, a first heating base 2, a sample tray 3, a drive motor 4, and a second heating mechanism 5. The first heating base 2 is arranged above the main frame 1, and the first heating base 2 is separated from the main frame 1 by a column 6. The first heating base 2 includes a base 21, an inner ring plate 22, and an outer ring plate 23. The inner ring plate and the outer ring plate 23 form a heating area 24. The output end of the drive motor 4 passes through the center of the inner ring plate and is connected to the sample tray 3. The second heating mechanism 5 is arranged on one side of the main frame 1. The sample tray 3 is provided with a sample cup groove 32 and a test tube groove 31. The test tube groove 31 is inside the sample cup groove 32, and the test tube groove 31 is aligned with the heating area 24. The base 21 is provided with a heating hole 8, and a heating rod is arranged in the heating hole 8. The heating rod heats the first heating base 2, so that heat is generated in the heating area 24 to heat the test tube. However, this heating effect cannot reach the required temperature. Therefore, a heat-conducting medium is arranged in the heating area 24. The heat-conducting medium is water, oil, or metal. The heating rod heats the heating area 24, and the test tube is heated through media such as water, oil, or metal, so as to achieve a better heating effect;

[0022] Therefore, an annular heat-conducting block 7 can be arranged in the heating area 24. A first heating groove 71 is arranged in the annular heat-conducting block 7. The annular heat-conducting block 7 is fixedly connected to the sample tray 3. When the drive motor 4 drives the sample tray 3 to rotate, the annular heat-conducting block 7 also rotates in the heating area 24. The test tube groove 31 is aligned with the first heating groove 71. The test tube is inserted into the first heating groove 71. When the heating rod heats the first heating base 2, the heat is transferred to the test tube through the annular heat-conducting block 7, so as to realize the heating of the test tube.

[0023] The second heating mechanism 5 includes a fixed frame 51, a motor 52, a slide rail 53, a slider 54, a lead screw 55, a nut sleeve 56, a connecting block 57, and a second heating base 58. The motor 52 is arranged on the fixed frame 51. The motor 52 is connected to the lead screw 55. The nut sleeve 56 is connected to the lead screw 55. The nut sleeve 56 is connected to the slider 54. The slider 54 is slidably matched with the slide rail 53. The connecting block 57 is fixedly connected to the nut sleeve 56. The second heating base 58 is arranged on the connecting block 57. A second heating groove 59 is arranged on the second heating base 58. The second heating groove 59 is aligned with the sample cup groove 32. The motor 52 can drive the lead screw 55 to rotate. When the lead screw 55 rotates, the nut sleeve 56 can drive the connecting block 57 and the second heating base 58 on the connecting block 57 to move up and down. When the second heating base 58 moves upward, the sample cup in the sample cup groove 32 will be wrapped by the second heating groove 59. Heating holes 8 are also arranged on the side wall of the second heating base 58, and heating rods are arranged in the heating holes 8, so as to realize the heating of the sample cup.
