This antifouling protecting cover not only is used for specially carrying out antifouling protection with the breathing machine joint, but also has for the sterile effect of breathing machine joint in the protection chamber 450, and direct movable mounting is in breathing machine U type frame, and spring wire 300 can stretch wantonly again, does not worry that antifouling protecting cover is lost, can take at any time, convenient to use.

As an optional embodiment, the two clamping wings 110 are movably connected by a torsion spring 113, each clamping wing 110 is provided with a semicircular groove 111, and after the two clamping wings 110 abut against each other, the two semicircular grooves 111 can be spliced to form the movable cavity 1110. The clamping ends of the clamping wings 110 are in a sawtooth shape, and the clamping ends of the two clamping wings 110 are meshed after being clamped. The two clip wings 110 are provided at their rear ends with a connection hole 112, and the connection hole 112 is connected to the spring 540 wire 300 through a detachable coil loop 200. After the bracket is arranged in the movable cavity 1110, the movable clamp 100 can move freely on the bracket, and is more flexible and applicable in use. The coil loop 200 may be a conventional key coil metal loop, which is easy to disassemble, and a plurality of protective covers 400 may be installed in the connection holes 112 through the spring wires 300 according to the number of terminals to be actually protected.

One end of the connecting block 310 is fixedly connected to the spring wire 300, and the other end is screwed to the first hard portion 410. After the liquid pre-filled in the disinfection liquid cavity 423 is used up, the connecting block 310 and the protective cover 400 are conveniently detached, the protective cover 400 is more convenient to replace, and the resource waste is reduced.

As shown in fig. 2, the flow control mechanism 500 includes a contact plate 510, a cross bar 520, a leak-proof boss 530, a spring 540, and a hard boss 550. The cross bar 520 is sleeved in the liquid outlet holes 4210, and two liquid outlet holes 4210 are oppositely arranged. The contact plate 510 is fixedly connected to the end of the protection cavity 450, and the inner wall of the protection cavity 450 is provided with a cotton layer 600 to cover the contact plate 510. The section of the disinfection liquid cavity 423 is fixedly connected with a leak-proof circular truncated cone 530, the leak-proof circular truncated cone 530 is wound on the outer wall of the cross rod 520, the leak-proof circular truncated cone 530 abuts against the inner layer 421, so that the liquid outlet hole 4210 is sealed, and a silica gel layer (not shown in the figure) covers the contact surface of the leak-proof circular truncated cone 530 and the inner layer 421. The end of the cross bar 520 located in the disinfectant chamber 423 is fixedly connected with one end of the spring 540, the other end of the spring 540 is fixedly connected with the hard round block 550, and the hard round block 550 is embedded in the outer layer 422. When the respirator joint extends into the protection cavity 450 from the elastic tying part 440, the joint can automatically squeeze the contact plate 510 to push the contact plate 510 to the direction of the disinfectant, at the moment, the spring 540 is compressed, the anti-leakage circular truncated cone 530 is far away from the liquid outlet hole 4210, the liquid flows to the protection cavity 450 from the gap of the liquid outlet hole 4210 and soaks the cotton layer 600 on the inner wall, the cotton layer 600 with the disinfectant surrounds the periphery of the joint, and the effect of contacting the disinfectant by the joint is better. After the respirator joint is pulled out, the spring 540 returns to push the side of the leak-proof circular truncated cone 530 with the silica gel layer to tightly abut against the liquid outlet hole 4210, so that liquid is prevented from flowing outwards.

The elastic binding portion 440 has a variable cross-sectional structure with a gradually increasing cross-sectional area from the non-connection end to the connection end, and the end with the largest cross-sectional area is fixedly connected to the second hard portion 430. When the elastic restricting opening part 440 covers the respirator connector, only the end with the smallest inner diameter tightly covers the connector, and the space is wider towards the second hard part 430, so that the elastic restricting opening part 440 can be conveniently detached.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all equivalent structures made by using the contents of the present specification and the drawings can be directly or indirectly applied to other related technical fields, and are within the scope of the present invention.
