The second connector 12 is connected to a hose 4. The end of the hose 4 is connected to a container for holding materials.

[0035] An inner cavity 14 is formed in the connecting member 1, and an intake pipe 5 and an exhaust pipe 6 are connected to the connecting member 1.

[0036] A material sensing unit is fixedly connected to the interior of the inner cavity 14 , and a signal output end of the material sensing unit is signal-connected to signal input ends of the first air pump 51 , the first valve 52 , the second air pump 61 and the second valve 62 .

[0037] When the material inside the reactor has completed its reaction and needs to be discharged, the operator can connect the discharge pipe 3 through the discharge valve on the discharge pipe 3. The material flows out from the reactor body and then passes through the discharge pipe 3, the connector 1, and the hose 4 in sequence before flowing into the container for holding the material. In the process of the material flowing through the inner cavity 14 of the connector 1, the material sensing unit senses the material and controls the first air pump 51, the first valve 52, the second air pump 61, and the second valve 62 to open. Nitrogen passes through the air intake pipe 5, the inner cavity 14, and the exhaust pipe 6 in sequence before flowing to the exhaust gas treatment system. In the process of nitrogen circulation, the volatile toxic gases can be discharged together to the exhaust gas treatment system for unified treatment, thereby reducing the occurrence of adverse effects on on-site operators caused by the emission of volatile toxic gases into the atmospheric environment.

[0038] It should be noted that in the embodiment of the present application, the portion of the hose 4 extending into the second connection part 12 is made of hard plastic, and a fourth sealing ring is installed between the discharge pipe 3 and the first connection part 11 and between the portion of the hose 4 extending into the second connection part 12 and the second connection part 12, respectively.

At the same time, the first sealing ring 131 and the first ring groove 532 can improve the tightness of the connection between the intake pipe 5, the exhaust pipe 6 and the connecting piece 1, which can effectively reduce the occurrence of toxic gas overflowing through the joints between the connecting piece 1 and the intake pipe 5, the exhaust pipe 6.

The intensity of the ultrasonic waves is attenuated, and the ultrasonic ranging sensor outputs a high-level signal. After identifying the high-level signal, the single-chip microcomputer determines that material has flowed out of the inner cavity 14 of the connector 1, and controls the first air pump 51, the first valve 52, the second air pump 61 and the second valve 62 to start so as to circulate nitrogen into the inner cavity 14 to discharge the toxic gas.
