Detailed Description
As shown in the attached drawings 1-4, the utility model comprises a hose 1, and a series pipe joint 2 and a one-way joint which are respectively arranged at two ends of the hose 1, wherein the series pipe joint 2 and the one-way joint are both used for being connected with a negative pressure suction device.
The one-way joint comprises a shell, a gasket 5 arranged in the shell and a one-way sealing ring 6 arranged below the gasket 5, wherein the one-way sealing ring 6 comprises a side ring 601 and a sealing cover 602 arranged on the inner side of the side ring 601 through a connecting column 603, a through hole is formed in the middle of the gasket 5, and the sealing cover 602 is matched with the through hole of the gasket 5 to realize sealing. The connecting column 603 has a certain elasticity, and when gas or liquid moves from top to bottom, the pressure overcomes the elasticity of the connecting column 603, so that a gap is formed between the sealing cover 602 and the gasket 5, and communication is realized. When the pressure of the sealing cover 602 is released, the sealing cover 602 is restored to the original position under the action of the elastic force, if liquid or gas flowing reversely occurs, upward pressure is also applied to the sealing cover 602, and the sealing cover 602 and the through hole of the gasket are still kept in a sealing state, so that the one-way circulation effect is realized. When the negative pressure suction device is detached, one end of the one-way joint is pulled out of the negative pressure suction device, so that the waste liquid can be effectively prevented from flowing backwards.
Preferably, the cover 602 is slightly larger than the through hole on the gasket 5, and a silicone membrane 7 with holes is arranged above the gasket 5, and the holes on the silicone membrane 7 correspond to the through hole on the gasket 5.
The casing includes last casing 3 and lower casing 4 of mutual lock, is equipped with first material mouth at the top of last casing 3, is equipped with the second material mouth in the bottom of casing 4 down, and through-hole and second material mouth on first material mouth, the packing ring 5 are linked together. The silicone membrane 7 is located between the upper shell 3 and the gasket 5, matched pressure grooves and pressure blocks are arranged between the upper shell 3 and the gasket 5, between the gasket 5 and the edge ring 601 and in front of the edge ring 601 and the lower shell 4, and the silicone membrane 7, the gasket 5 and the edge ring 601 are compacted and sealed after the upper shell 3 and the lower shell 4 are buckled.
The contact surface of the upper shell 3 and the lower shell 4 is provided with a connecting groove and a connecting bulge which are matched with each other, so that the upper shell and the lower shell are connected conveniently, and the upper shell and the lower shell are connected into a whole through welding after being buckled.
Preferably, a clamping ring 8 is arranged on the top surface of the lower shell 1, the outer side wall of the clamping ring 8 is matched with the inner side wall of the upper shell 1, and the inner side wall of the clamping ring 8 is matched with the outer side wall of the gasket 5.
Preferably, the housing further comprises a cap mounted on the hose 1 or the lower housing 4 by means of a flexible rod 9, said cap cooperating with the first spout of the upper housing 3 to cover it.
