the servo motor 81 can also drive the eccentric wheel 111 to rotate in the forward and reverse operation process, and the eccentric wheel 111 can continuously drive the two suction structures to operate when rotating, and because the specific structures of the two suction structures are completely the same, only the working principle of any one suction structure is described here: when the eccentric wheel 111 presses the connecting rod 1124, the connecting rod 1124 can drive the sliding plug 1122 to move and press the first spring 1123, when the eccentric wheel 111 is separated from the connecting rod 1124, the sliding plug 1122 can reset under the elastic force of the first spring 1123, so that the sliding plug 1122 can continuously reciprocate in the sealing cylinder 1121 along with the rotation of the eccentric wheel 111, because the flow limiting directions of two one-way valves 1126 are opposite, in particular, one-way valve 1126 can limit the gas or the liquid to only enter the sealing cylinder 1121, the other one-way valve 1126 can limit the gas or the liquid to only flow out from the sealing cylinder 1121, therefore, when the sliding plug 1122 moves towards one direction, the sliding plug 1122 can perform suction action, when the sliding plug 1122 moves towards the other one direction, the sliding plug 1122 can perform discharge action, as shown in the summary, when the two suction structures operate, one of the suction structures sucks and discharges the liquid and the other suction structure sucks and discharges the gas, so that with the operation of the eccentric wheel 111, one of the suction structures can continuously suck the heat transfer oil accumulated between the outer tube 92 and the inner tube 93 and discharge the heat transfer oil at high temperature into the inside of the stirring vane 83, the heat transfer oil in the stirring vane 83 enters between the outer tube 92 and the inner tube 93, the heat transfer oil circulates between the outer tube 92 and the stirring vane 83, the stirring vane 83 can be warmed up after the heat transfer oil enters the inside of the stirring vane 83, the warmed stirring vane 83 can heat the sample through the inside of the sample, thereby improving the heating efficiency and heating effect of the device on the sample, the other suction structure continuously sucks the air in the external environment, pumps the gas into the inside of the inner tube 93, the gas enters the inside of the cavity 101 after passing through the inner tube 93, the high-temperature heat conduction oil can heat the air flow flowing in the inner layer pipe 93 in the process of flowing through the inner layer pipe 93 through the plurality of spray holes 102, so that the temperature of the air flow is increased, under the condition, the air can continuously form upwards-rushed air bubbles in the sample, the air bubbles can also play a role in stirring the sample, in addition, the high-temperature air can also comprehensively heat the sample, the heating efficiency and the heating effect of the device on the sample are further improved, the rotating shaft 82 and the mounting pipe 104 are connected through the rotating joint 103, the rotating joint 103 is designed to enable the rotating shaft 82 and the mounting pipe 104 to rotate relatively, the mounting pipe 104 is prevented from being wound on the rotating shaft 82, and meanwhile, the moving interference between the rotating shaft 82 and the mounting pipe 104 is avoided;
The cover assembly is arranged on the rotating shaft 82, when the rotating shaft 82 descends, the rotating ring 132 descends along with the rotating shaft, the top cover 131 can be driven to move downwards through the third spring 133 when the rotating ring 132 descends, so that the top cover 131 covers the tank opening of the heating tank 5, at the moment, the top cover 131 can block the tank opening of the heating tank 5 to avoid heat dissipation through the tank opening of the heating tank 5, the temperature rising speed of a sample in the heating tank 5 can be improved through the design, and the rotating ring 132 is rotatably arranged on the rotating shaft 82;
After heating, a worker starts the air cylinder 4, so that the air cylinder 4 drives the sliding frame 3 to move downwards, the servo motor 81 and the rotating shaft 82 also move downwards along with the sliding frame, the rotating shaft 82 can drive the pressing rod 126 to move downwards when moving downwards until the pressing rod 126 presses the plugging core 124, the plugging core 124 moves downwards, the opening 123 is not plugged when the plugging core 124 moves downwards, at the moment, liquid in the heating tank 5 flows out through the opening 123 and the discharge opening 121 and flows into the collecting tank 6, and because the collecting tank 6 does not participate in the heating process, the surface temperature of the collecting tank 6 is lower, so that the worker can conveniently hold the collecting tank 6 directly, and transfer samples in the collecting tank 6 and the collecting tank 6;
The device also has the function of flushing the heating tank 5, after finishing the heating work of the sample, the worker adjusts the three-way valve 141 to enable the water inlet pipe 142 to be communicated with the connecting pipe 1125 for exhausting, then the worker starts the servo motor 81 to enable the eccentric wheel 111 to rotate, and further two pumping structures are operated, when the two pumping structures are operated, the pumping structures originally used for exhausting are continuously pumping water in the water tank 143 through the water inlet pipe 142 and pumping the water into the cavity 101, then water flows are sprayed out through the plurality of spray holes 102 and are sprayed towards the inner wall of the heating tank 5, so that the flushing effect is achieved on the inner wall of the heating tank 5, the phenomenon of cross contamination on different samples during heating can be avoided due to the flushing effect, and the detection precision is ensured.
