Description
Technical field this utility model relates to a kind of appliances for labor protection, especially is applicable to the electrogas welding mask that is used to protect that the electrogas welding workman wears when work.
Background technology is present, the electrogas welding workman is when work, because the high temperature that electric arc or acetylene gas burning produce makes welding agent and metal that violent chemical reaction take place, produce multiple harmful gas and metal powder granulates, so operator's physical and mental health is worked the mischief.Existing common health gauze mask can not satisfy at this working environment air has been carried out filtering requirement.
The summary of the invention the purpose of this utility model provides a kind of electrogas welding mask of simple in structure, good filtration effect.
For achieving the above object, this utility model electrogas welding mask comprises cover body, cover rope, but the micro-filtration membrane of filtered air is arranged in the flexible light weight box of cover body front end, and box body back central authorities offer passage, offers the flexible panel and the flexible light weight box gummed of air inlet; Be connected with the projection of the back side central authorities of flexible light weight box with the oronasal mask of human body face contact, the bottom of oronasal mask is provided with venthole.
After adopting this structure, air sucks for human body in the passage inlet port nose cup at the air inlet of flexible panel, micro-filtration membrane, box body back, and the gas that human body is breathed out is discharged through the venthole of oronasal mask bottom.Because micro-filtration membrane has the function of filtered air, so can be with airborne harmful gas, the elimination of metallic dust granule; Reach the purpose of air in cleaning, the purification inlet port nose cup.
As further improvement of the utility model, described diaphragm that can unidirectional unlatching is located on the middorsal passage of box body.Adopt this structure to guarantee that the unidirectional of gas enters, discharges with inlet close when the human body breath.
The utility model has the advantages that: simple in structure, good filtration effect, the operator can not produce discomfort owing to wearing mask when work.
Description of drawings Fig. 1 is the cross-sectional view of this utility model electrogas welding mask.
The specific embodiment as shown in Figure 1, this utility model electrogas welding mask has cover body, elastic covering rope 8, but with the latus rectum of filtered air is that micro-filtration membrane 9 folding mats of 0.1 μ m are put in the flexiplast lightweight box 2 of the cover body front end of apery dignity portion, the drilling of box body back central authorities has passage 4, and the flexiplast panel 1 that offers air inlet 1-1 is bonding by epoxy glue with flexible light weight box 2; Be connected with the projection of the back side central authorities of flexible light weight box 2 with the facial rubber system oronasal mask 3 human body face contact and imitative, the bottom of oronasal mask is provided with venthole 7.Diaphragm 5 that can unidirectional unlatching fixes on the middorsal passage 4 of box body by moulding 6 rivetings of cotter nail.Elastic covering rope 8 is sewn to the rear end of oronasal mask 3.
In actual use, operator's inhaled air with the dust in the airborne harmful smoke, metal powder granulates elimination, reaches the purpose of purification, cleaning suction air behind the micro-filtrate membrane filtration of this utility model electrogas welding mask.The gas that human body is breathed out, saliva are discharged through the venthole of oronasal mask bottom.
The utlity model has simple in structure, good filtration effect, owing to can guarantee unidirectional suction, the discharge of gas, the operator can not produce discomfort because of wearing mask when work; Be a kind ofly to prevent that preferably the appliances for labor protection of respiratory tract occupational disease from appearring in the electrogas welding workman.
