Specifically, the present embodiment provides the check valve 241 to close the exhaust passage 24, so as to prevent external foreign matters from entering the exhaust passage 24.
As shown in fig. 9 and 12, further, based on the above-described embodiment, the second plugs are provided with the second exhaust passages 223 corresponding to each accommodation groove 221, respectively, one end of the second exhaust passage 223 communicates with the corresponding accommodation groove 221, and the other end of the second exhaust passage 223 communicates with the exhaust passage 24. So configured, when the vent top ring 25 opens the one-way vent valve 171, the gas in the airbag 17 enters the first vent passage 222 through the one-way vent valve 171, enters the vent passage 24 through the first vent passage 222, and thus the impurities are discharged out of the connector, and because the flow rate of the second vent passage 223 is slower than that of the vent passage 24, the second vent passage 223 can generate suction force under the bernoulli effect, and the impurities attached to the surface of the second insertion stage 22 and the cleaning strip 142 are sucked into the second vent passage 223 and then discharged through the vent passage 24.
The foregoing description is only one preferred embodiment of the invention, and therefore all changes and modifications that come within the meaning and range of equivalency of the structures, features and principles of the invention are intended to be embraced therein.
