Abstract
The utility model discloses a dustproof and antitoxin cooling mask for a welder. The dustproof and antitoxin cooling mask is characterized by comprising a dustproof and antitoxin casing, a dustproof mask and an air delivery pipe, all of which are arranged on a mask support, wherein the dustproof and antitoxin casing is a protective cover with an end face taking the shape of a trapezoid-shaped slot, the outer side of the dustproof and antitoxin casing is provided with a filter screen, the inner side of the dustproof and antitoxin casing is provided with the air delivery pipe which is an annular pipe with a plurality of uniformly and densely distributed air outlets and tee-joint adapter pipes, and the filter screen is in buckled connection with the dustproof and antitoxin casing through buckles at two sides of the filter screen; the dustproof mask is a silicon rubber mask provided with an inhalation valve and an exhaust valve, and the mask is provided with a tying belt and a hasp; and the dustproof and antitoxin casing and the dustproof mask are respectively and fixedly arranged at the inner side and the outer side of the mask support. Compared with the prior art, the dustproof and antitoxin cooling mask disclosed by the utility model has the advantages of simple structure, comfortableness for wearing, smoothness for breath, no influence on welding and other operation and good cooling effect and is favorable for greatly improving the operation environment of operators in high-temperature climate, ensuring welding quality and improving working efficiency.
Description
Technical field
The utility model relates to the labour protection articles for use technical field, and specifically a kind of dust, high temperature or welder poisonous, the pernicious gas operating environment use dustproof and gas defence cooling mouth mask.
Background technology
Most important operation is welded exactly in the steel construction production process, well-known welding is a field operation that accompanies with high temperature, especially summer time weld job be in for a long time under the hot environment and work, thick and heavy welder's clothes are substantially drenched, the welder suffers heatstroke easily, so that welding quality can't guarantee, affects production efficiency and product quality.And existing cooling means, as ventilating and wearing thin clothing and limit because of welding process requirement and occupational protection requirement, the operating area can not adopt cooling fan directly to dispel hot-air to lower the temperature, yet ice cube and spray cooling not only expense are high, effect is not good yet, increase the humidity of operation field, because the operation place exists thawing frozen water and operating personnel self the sweat personnel that cause easily to get an electric shock, the safety utilization of electric power risk is larger, how to improve the welder in the operating environment of high temperature season, solve the welder, the painter, work post cooling in summer time such as polishing worker etc. and guarantee that instrument uses, and dust in the cancel job environment, benzene and benzene compound are to the human injury in the paint.Improve welding efficiency and quality and perplexing steel construction production always.
The utility model content
The purpose of this utility model is that a kind of welder who designs for the deficiencies in the prior art uses dustproof and gas defence cooling mouth mask, adopt the compressed air of cleaning as the respiratory gas source of face shield, and in mouth mask, form malleation, stop air-polluting entering, the user can regulate tolerance as required, make breathing more comfortable, welding, polishing and the paint of especially applicable manufacture of steel structure industry air pollution, dust is serious and air in contain in the operating environment of toxic gas and use.
The concrete technical scheme that realizes the utility model purpose is: a kind of welder is with preventing dust and gas defence cooling mouth mask, be characterized in that this prevents dust and gas defence cooling face shield is comprised of dustproof and gas defence shell, protective mask and the appendix that are arranged on the mask support frame, described dustproof and gas defence shell is the protective cover that end face is dovetail groove, its outside is provided with screen pack, the inboard is provided with appendix, described appendix is the ring pipe of evenly densely covered several exhaust vents and t-joint, and screen pack is by both sides buckle and dustproof and gas defence shell snapping; Described anti-dust respirator is the silica gel face shield that is provided with inlet valve and air bleeding valve, and its face shield is provided with frenulum and hasp; Prevent dust and be fixedly installed on respectively the inside and outside both sides of mask support frame with gas defence shell and anti-dust respirator.
Described t-joint is provided with the source of the gas control valve that is connected with flexible pipe.
The utility model compared with prior art has simple in structure, wear comfortable, breathe smooth and easy, do not affect the welding or other operation, good cooling effect has been improved the operating environment of operating worker at high temperature season greatly, guarantees welding quality, increases work efficiency.
Description of drawings

The specific embodiment
Consult accompanying drawing 4, described appendix 5 is the ring pipe of evenly densely covered several pores 15 and t-joint 9, and described t-joint 9 is provided with the source of the gas control valve 16 that is connected with flexible pipe 6.
The utility model is to use like this: anti-dust respirator 10 is worn at the scene operating worker mouth, with frenulum 3 and hasp 12 tightens, then flexible pipe 6 just is connected and can uses with the compressed air of production scene, source of the gas control valve 16 can be regulated the air quantity of exhaust vent 15, make breathing more comfortable, play air-polluting the entering and cooling effect of isolation, welding, polishing and the paint of especially applicable manufacture of steel structure industry air pollution, dust is serious and air in contain in the operating environment of toxic gas and use, improve the welder in the operating environment of high temperature season.
More than just the utility model being further described, is not to limit this patent, and all is that the utility model equivalence is implemented, and all should be contained within the claim scope of this patent.
