After passing through the fourth pipe 703, the buffer enters the third connection port 7041, and then enters the corresponding first three-way joint 501 through the corresponding pipe from the fourth connection port 7042. The rocker arm liquid adding mechanism 50 adds the buffer into the corresponding centrifugal sample tube 13 through the left pipe of the corresponding first three-way joint 501. When emptying, the second air port 802 is connected with the second inlet and outlet 803. Driven by the second liquid adding pump 701, the air sucked from the second air port 802 passes through the fourth pipe 703 and enters the third connection port 7041, and then enters the rocker arm liquid adding mechanism 50 through the corresponding pipe from the fourth connection port 7042, so as to empty the buffer remaining in the second multi-valve 704 and the rocker arm liquid adding mechanism 50.

[0042] Furthermore, if Figure 1 As shown, the liquid circuit system also includes: a waste liquid temporary storage mechanism 90, a waste liquid suction and discharge control mechanism 11 and a waste liquid collecting mechanism 12; the liquid circuit input end of the waste liquid temporary storage mechanism 90 is connected to the rocker arm liquid adding mechanism 50, the liquid circuit output end of the waste liquid temporary storage mechanism 90 is connected to the waste liquid collecting mechanism 12, and the gas circuit output end and the gas circuit input end of the waste liquid temporary storage mechanism 90 are both connected to the waste liquid suction and discharge control mechanism 11.

The liquid suction and discharge control mechanism 11 extracts the air in the temporary storage tank 902, so that the temporary storage tank 902 is in a negative pressure state. When the middle pipe of the first three-way joint 501 of the rocker arm liquid adding mechanism 50 contacts the waste liquid in the centrifugal sample tube 13, the liquid suction solenoid valve 903 is opened, and the waste liquid passes through the rocker arm liquid adding mechanism 50 and the waste liquid suction pipe 901 and enters the temporary storage tank 902 for temporary storage.

The waste liquid suction and discharge control mechanism 11 inputs air into the temporary storage tank 902, so that the temporary storage tank 902 is in a positive pressure state, and the waste liquid in the temporary storage tank 902 is forced into the waste liquid collection mechanism 12. During the entire process of sucking and discharging the waste liquid, the waste liquid has no contact with the waste liquid suction and discharge control mechanism 11, thereby reducing the probability of clogging of components. At the same time, the principle of negative pressure suction of waste liquid can store energy in advance, and the negative pressure suction force is much greater than that of a traditional waste liquid pump, thereby solving the problem of uneven suction caused by uneven pressure in a single tube.

[0045] In actual application, the third control valve 111 and the fourth control valve are both three-way solenoid valves. When the waste liquid suction and discharge control mechanism 11 controls the suction of waste liquid, the first air inlet is controlled to be connected with the first air outlet, and the third air inlet is controlled to be connected with the second air outlet. The air in the temporary storage tank 902 is sucked by the drive of the air pump 116 component, and the air in the temporary storage tank 902 is discharged after passing through the fifth pipeline, the third control valve 111, the air pump 116 component and the fourth control valve, so that the temporary storage tank 902 is in a negative pressure state. When the waste liquid suction and discharge control mechanism 11 controls the discharge of waste liquid, the second air inlet is controlled to be connected with the first air outlet, and the third air inlet is controlled to be connected with the third air outlet. The atmospheric air is sucked by the drive of the air pump 116 component, and the atmospheric air passes through the third control valve 111, the air pump 116 component, the fourth control valve and the sixth pipeline and the fifth pipeline 114 and then enters the temporary storage tank 902, so that the temporary storage tank 902 is in a positive pressure state. Specifically, the air pump 116 component includes: at least one air pump 116; when there is one air pump 116, the input end of the air pump 116 is connected to the first air outlet through a pipeline, and the output end of the air pump 116 is connected to the third air inlet through a pipeline; when there are multiple air pumps 116, the input ends of the multiple air pumps 116 are connected to the second multi-pipe connector 117 through a pipeline, the second multi-pipe connector 117 is connected to the first air outlet through a pipeline, the output ends of the multiple air pumps 116 are connected to the third multi-pipe connector 118 through a pipeline, and the third multi-pipe connector 118 is connected to the third air inlet through a pipeline.

[0046] Furthermore, the waste liquid suction and discharge control mechanism 11 further includes: a pressure sensor 115 ; the pressure sensor 115 is arranged on the sixth pipeline and the fifth pipeline 114 .

[0047] Specifically, the pressure sensor 115 is arranged on the sixth pipeline and the fifth pipeline 114 through the second three-way joint 119. The pressure sensor 115 detects the pressure in the temporary storage tank 902, and controls whether the air pump 116 continues to drive according to the pressure detected by the pressure sensor 115, so as to control whether to continue to extract the air in the temporary storage tank 902, or control whether to continue to input air into the temporary storage tank 902, so as to facilitate the control of the waste liquid volume sucked into the temporary storage tank 902 and the waste liquid volume discharged from the temporary storage tank 902.

[0048] Furthermore, the waste liquid collection mechanism 12 includes: a fifth control valve 121, a waste liquid barrel 122, a seventh pipe 123 and an eighth pipe 124; one end of the seventh pipe 123 is connected to the liquid circuit output end, and the other end of the seventh pipe 123 is connected to the input end of the fifth control valve 121, one end of the eighth pipe 124 is connected to the output end of the fifth control valve 121, and the other end of the eighth pipe 124 is connected to the inlet of the waste liquid barrel 122.

[0049] In actual application, the fifth control valve 121 is a solenoid valve. When the temporary storage tank 902 is positively pressure controlled, the air pump 116 works, and the atmospheric air enters the third control valve 111, the air pump 116 assembly, the fourth control valve and the sixth pipeline and the fifth pipeline 114 from the second air inlet, and then enters the temporary storage tank 902, and the waste liquid in the temporary storage tank 902 is output through the bottom pipeline in the bottle. The fifth control valve 121 is opened, and the waste liquid is pressed into the waste liquid barrel 122 to complete the collection of the waste liquid.
