Description
Technical field
This utility model relates to a kind of Auto-changing Shade Welding Mask Made.
Background technology
Welding mask can effectively prevent the strong arc light produced in weld job process to the injury of eye, and each harmful gas of splash etc. of appearance causes infringement to face, reduces the generation of skin burn disease.Before the welding starting the arc; electric welder's helmet is on state of; the position of weld seam can be observed clearly to avoid the starting the arc blindly; and the brightness (this brightness can regulate) required when the moment automatic light-changing electric-welding face guard of the starting the arc controls within the extremely short time that liquid crystal lens is dimmed reaches welding; protect the eyes of people not by the injury of electro-welding arc; and whole welding process can be observed clearly, ensure welding quality, thus improve speed of welding.After welding completes, electric welder's helmet must return on state of wait and weld next time, to avoid the twilight sunset of welding high temperature generation to the injury of eye.Present traditional Auto-changing Shade Welding Mask Made, can not protect weld job personnel away from the injury producing a large amount of harmful gas dust during welding when weld job.
Utility model content
For solving above-mentioned prior art Problems existing; the utility model proposes a kind of Auto-changing Shade Welding Mask Made; this welding mask can protect weld job personnel away from the injury producing a large amount of harmful gas dust during welding when weld job, ensure the work health safety of weld job personnel.
The technical solution of the utility model is achieved in that
A kind of Auto-changing Shade Welding Mask Made, comprise face shield, headband, U-shaped discharge pipe, flexible ajutage, pressure fan and belt, described headband arranges above described face shield, described U-shaped airduct one end is located in described face shield, its other end is connected with one end of described flexible ajutage, the other end of described flexible ajutage is connected with described pressure fan, and described blower setting is in the middle of described belt; Described U-shaped discharge pipe is flexibly connected with between described headband.
Further, described pressure fan is brush DC turbofan, is provided with air-purifying net in described pressure fan.
Further, described air-purifying net is made up of filter cotton, sponge and rustless metal net.
Further, the air inlet protecgulum of described pressure fan is for being threaded into tuyere-type air inlet protecgulum, and described air-purifying net is fixed in described pressure fan by described air inlet protecgulum.
Further, described U-shaped discharge pipe is provided with draw-in groove, and described headband is through described draw-in groove.
The beneficial effects of the utility model:
