Wherein the sample processing module 101 can drain waste through its waste port to allow the waste to flow to a subsequently connected module.

The connection module 102 connects the waste liquid port of the sample processing module 101, and the connection module 102 and the waste liquid port have the same height in the vertical direction.

Wherein the connection module 102 may be configured to conduct at least two ports connected thereto such that the ports connected by the connection module 102 are in communication with each other.

The first opening of the waste liquid storage module 103 is connected to the connection module 102, and the height of the waste liquid storage module 103 in the vertical direction is smaller than the height of the connection module 102 in the vertical direction.

The connection module 102 may specifically enable the first opening of the waste liquid storage module 103 to communicate with the waste liquid port of the sample processing module 101, that is, enable the waste liquid discharged from the sample processing module 101 to flow into the waste liquid storage module 103 through the connection module 102.

As shown in fig. 1, the vertical direction D1 may specifically refer to a gravitational direction, and the greater the height of the mass object in the gravitational direction, the greater the gravitational potential energy, and the smaller the height, the smaller the gravitational potential energy.

In addition, the waste liquid storage module 103 may further have a second opening, and the second opening of the waste liquid storage module 103 may be connected to the external space B, so as to maintain the air pressure balance inside and outside the waste liquid storage module 103 by sucking or discharging air through the external space B, thereby improving the safety.

Specifically, the first opening of the check valve 104 is used to communicate a, which may refer to an external space, and air in the external space may enter the pipeline between the three-way joint 1021 and the waste liquid storage module 103 through the first opening of the check valve 104.

The one-way valve 104 may allow air to pass only from its first opening to its second opening and may not allow air to pass from the second opening to the first opening.

Based on the above-mentioned mode, can avoid sample processing module 101 when discharging the waste liquid, the condition that the waste liquid flows out from the second opening of three way connection 1021 and pollutes waste liquid storage module 103 takes place, and still can be full of the waste liquid between sample processing module 101, connecting module 102 and waste liquid storage module 103, and when sample processing module 101 stops discharging the waste liquid, through the effect of gravity between connecting module 102 and waste liquid storage module 103, the cooperation three way connection 1021 is from the air that the A received, can make the waste liquid flow to waste liquid storage module 103 between connecting module 102 and the waste liquid storage module 103, thereby realize the evacuation to the waste liquid in this section pipeline, reduce the time overlength that blocks up in this section pipeline because of the waste liquid and cause the possibility of damage to this section pipeline, also can reduce the possibility that the condensate blocks up the pipeline because of the time overlength of waste liquid degree in this section pipeline, further improve waste liquid conveyor's reliability.

Based on the above structure, after the sample processing module 101 stops generating the waste liquid, the first pipeline M1 will have the waste liquid, but the second pipeline N1 will not have the waste liquid, under the action of gravity, the air in the waste liquid storage module 103 will enter the second pipeline N1, and the waste liquid in the first pipeline M1 will flow into the waste liquid storage module 103 to form the replacement of air and waste liquid, thereby realizing the evacuation of the waste liquid in the pipeline, reducing the possibility of damage to the pipeline due to the overlong time of the blockage of the waste liquid in the pipeline, and also reducing the possibility of forming the condensate blockage pipeline due to the overlong time of the waste liquid in the pipeline, and improving the reliability of the waste liquid conveying device.

Further, at least part of the second pipes 106 are part of all of the second pipes 106 directly connected to the second opening of the three-way joint 1021.

Specifically, as shown in fig. 4, the pipeline of the D portion is directly connected to the three-way joint 1021, and no other pipeline exists between the pipeline of the D portion and the three-way joint 1021, so that the possibility that the waste liquid is blocked in the pipeline of the D portion and cannot be discharged due to the fact that the height of the pipeline of the D portion is not higher than that of the three-way joint 1021 is reduced, the possibility that a condensate is blocked in the pipeline due to the fact that the waste liquid is excessively long in the pipeline of the segment is further reduced, and the reliability of the waste liquid conveying device is improved.
