Pipe II, bellows III, the dust-proof head-shield is interior to be provided with safe head-shield, and ripple is fixed in the safe head-shield lower section by fixed strip
Pipe I, the bellows I are connected with bellows II by fast joint, and bellows II is fixed on dust-proof head-shield by magic tape, institute
State bellows III one end and be connected to bellows I centre positions, the bellows I, bellows II, bellows III outside are all provided with
Have a crimp ring, steel wire screw thread be installed on the inside of crimp ring, bellows III a diameter of 3.5CM, bellows I, bellows II it is straight
Footpath is 2.7CM, and the bellows II is provided with two steam vents, respectively first row steam vent and second row steam vent, described
Bright film is located in front of safe head-shield.
Wherein, the length of the bellows I is the length around the edge 3/5 of safe head-shield.
Wherein, the bellows II is shaped as " u "-shaped, the first row steam vent that bellows II is provided with and hyaline membrane phase
Right, second row steam vent is relative with the mouth and nose of human body head.
Wherein, the first row steam vent is identical with the exhaust hole number of second row steam vent, and is vented hole number and exists
Between 6-10.
Wherein, the bellows III and bellows I connected mode bonds afterwards first to suture.
Wherein, described bellows III one end is connected with bellows I, and the other end is connected with pressure fan.
Wherein, the position of the bellows II is relative with the position of hyaline membrane.
The beneficial effects of the invention are as follows：A kind of bellows for dust-proof head-shield provided by the invention, realizes dust-proof head
Air-supply in cover, by the connections of such a three sections of bellowss can without using Double-layered transparent film in the case of in dust-proof head-shield
Staff's breathing it is smooth, and fog will not be produced.
In order to be further understood that the feature of the present invention and technology contents, refer to below in connection with the detailed of the present invention
Illustrate and accompanying drawing, however accompanying drawing only provide with reference to and explanation use, be not used for being any limitation as the present invention.
