[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1 and Figure 4 This utility model provides an embodiment of a sample detection and extraction temperature control device, comprising a base 1, an insulation sleeve 2 fixedly connected to the top of the base 1, an extraction vessel 3 fixedly connected to the middle of the insulation sleeve 2, and an electromagnetic coil 21 fixedly connected inside the base 1, located directly below the extraction vessel 3. First, the sample is placed inside the extraction vessel 3. The electromagnetic coil 21 quickly heats the sample inside the extraction vessel 3. The temperature change inside the extraction vessel 3 can be observed through a thermometer on the top of the extraction vessel 3, and the temperature of the sample inside the extraction vessel 3 can be maintained by controlling the voltage supply.

[0035] Reference Figures 1-4A water tank 4 is fixedly connected to the top of the base 1. A semiconductor cooling chip 11 is fixedly connected to the middle of the left wall of the water tank 4. A water outlet pipe 10 and a water inlet pipe 19 are fixedly connected to the front and rear sides of the water tank 4, respectively. Two centrifugal pumps 5 are fixedly connected to the top of the base 1. The ends of the water outlet pipe 10 and the water inlet pipe 19 away from the water tank 4 are respectively connected to the input ends of the two centrifugal pumps 5. A connecting assembly is installed at the output end of the centrifugal pumps 5. A connecting port 2 16 and a connecting port 14 are fixedly connected to the front and rear sides of the insulation sleeve 2, respectively. The insulation sleeve 2 and the extraction tank 3 are connected together. A guide plate 15 is installed, which is spiral in shape. The connecting assembly includes two diversion pipes 6, which are fixedly connected to the output ends of two centrifugal pumps 5 respectively. A solenoid valve 7 is installed in the middle of each of the two diversion pipes 6. One diversion pipe 6 is fixedly connected to a water supply pipe 8 and a connecting pipe 17 at its two ends away from the outlet pipe 10, and the other diversion pipe 6 is fixedly connected to a return pipe 9 and a connecting pipe 2 18 at its two ends away from the inlet pipe 19. The water supply pipe 8 is connected to the connecting port 2 16, and the return pipe 9 is connected to the connecting port 14. The semiconductor cooling chip 11 can quickly cool the water in the water tank 4. When the temperature inside the extraction tank 3 is too high, the centrifugal pump 5 can be driven to extract the cooling water from the water tank 4 through the outlet pipe 10 and open the solenoid valve 7 at the connection between the diversion pipe 6 and the water supply pipe 8, so that the cooling water can be delivered between the insulation jacket 2 and the extraction tank 3, thereby quickly cooling the extraction tank 3 and the sample inside the extraction tank 3 and preventing the temperature inside the extraction tank 3 from becoming too high. At the same time, under the action of the spiral guide plate 15, the turbulence effect of the cooling water in the insulation jacket 2 can be improved, thereby improving the cooling efficiency of the cooling water. At the same time, the solenoid valve 7 between another diversion pipe 6 and the return water pipe 9 is opened, and another centrifugal pump 5 is driven to allow the cooling water in the insulation jacket 2 to return to the water tank 4 through the inlet pipe 19 through the connection port 14, the return water pipe 9 and the diversion pipe 6, thereby avoiding the waste of water resources.

[0036] Reference Figures 4-6A heat dissipation hole 20 is provided on the left side of the base 1. A cooling fan 24 is fixedly connected to the middle of the base 1. A filter screen 12 is slidably connected to the middle of the right wall of the base 1. A round rod 26 is rotatably connected to the middle of the base 1. A knob 13 is fixedly connected to one end of the round rod 26. A gear 27 is fixedly connected to the other end of the round rod 26. A rack 28 is slidably connected to the middle of the base 1. The rack 28 meshes with the gear 27. A movable plate 29 is fixedly connected to the end of the rack 28 away from the gear 27. An insertion rod 30 is fixedly connected to the middle of the movable plate 29. The insertion rod 30 is slidably connected to the middle of the filter screen 12. An insertion hole 32 is provided in the middle of the filter screen 12. The insertion rod 30 is slidably connected to the middle of the insertion hole 32. An elastic component is installed in the middle of the base 1. The elastic component includes a connecting rod 31. The connecting rod 31 is fixedly connected to the middle of the base 1. The movable plate 29 is slidably connected to the outer periphery of the connecting rod 31. A compression spring 25 is sleeved on the outer periphery of the connecting rod 31. The cooling fan 24 drives the airflow to continuously expel the heat generated by the electromagnetic coil 21 through the heat dissipation hole 20, thereby preventing the electromagnetic coil 21 from short-circuiting due to overheating. At the same time, the filter screen 12 filters the dust in the air, preventing dust from adhering to the electromagnetic coil 21. After the filter screen 12 has been filtering for a long time, turning the knob 13 drives the round rod 26 to rotate, which in turn drives the gear 27 to rotate. The gear 27 moves the rack 28, which, through the movable plate 29, drives the insertion rod 30 to slide out from the middle of the insertion hole 32, so that the filter screen 12 can be quickly removed for cleaning, thereby preventing the filter screen 12 from being blocked by dust and ensuring airflow. At the same time, as the movable plate 29 moves, it slides on the outer periphery of the connecting rod 31 and squeezes the compression spring 25. After releasing the knob 13, the compression spring 25 can push the movable plate 29 and the insertion rod 30 to quickly return to their original positions, so as to quickly install and fix the filter screen 12.

[0037] Reference Figure 1 and Figure 4 A support plate 22 is fixedly connected inside the base 1. A circulation pipe 23 is fixedly connected to the middle of the support plate 22. The two ends of the circulation pipe 23 are connected to connecting pipe 17 and connecting pipe 18, respectively. The circulation pipe 23 is located between the electromagnetic coil 21 and the cooling fan 24. By opening two of the solenoid valves 7, the centrifugal pump 5 can input the cooling water in the water tank 4 into the circulation pipe 23 through connecting pipe 17, and under the action of connecting pipe 18, it can flow back into the water tank 4. This allows the air input by the cooling fan 24 to come into contact with the circulation pipe 23 and reduce its temperature, thereby improving the cooling effect on the electromagnetic coil 21.

[0038] Working principle: First, the sample is placed inside the extraction tank 3. The sample inside the extraction tank 3 can be quickly heated by the electromagnetic coil 21. The temperature of the sample inside the extraction tank 3 can be maintained by controlling the voltage supply. When the temperature inside the extraction tank 3 is too high, the centrifugal pump 5 is driven to draw cooling water from the water tank 4 through the water outlet pipe 10 and open the solenoid valve 7 at the connection between the diversion pipe 6 and the water supply pipe 8, so that the cooling water can be delivered between the insulation jacket 2 and the extraction tank 3, thereby quickly cooling the extraction tank 3 and the sample inside the extraction tank 3 and preventing the temperature inside the extraction tank 3 from becoming too high.

[0039] The cooling fan 24 drives the airflow to continuously expel the heat generated by the electromagnetic coil 21 through the heat dissipation hole 20, thereby preventing the electromagnetic coil 21 from short-circuiting due to overheating. After the filter screen 12 has been filtering for a long time, turning the knob 13 drives the round rod 26 to rotate, which in turn drives the gear 27 to rotate. At the same time, the gear 27 moves the rack 28. The rack 28 drives the insertion rod 30 to slide out from the middle of the insertion hole 32 through the movable plate 29, so that the filter screen 12 can be quickly removed for cleaning, thereby preventing the filter screen 12 from being blocked by dust and ensuring the airflow effect.
