Abstract
The utility model provides a self-suction type electric welding protective mask with air purification function, which is suitable for the electric welding operation under multiple environmental conditions; the utility model comprises a protective mask (1), an oronasal mask (2) installed at the inner side of the protective mask, an air duct (4), an air purification filtration chamber (3), etc.; the air purification filtration chamber (3) which is connected with the oronasal mask (2) through the air duct (4) is arranged on the top of the inner side of the protective mask, and the air purification filtration chamber (3) is internally provided with a replaceable filter element; in the utility model, the protective mask is fixed on the face by a lace, and when in work, the breathing quality of electric welding operators can be effectively improved; furthermore, the self-suction type electric welding protective mask has simple structure, low cost, convenient usage and good air filtering effect.
Description
Technical field
This utility model relates to a kind of labor protection instrument, is specially a kind of self-priming air cleaning electric welding protective mask that is applied to electric welding field.
Background technology
At present, the face protection cover of using in the electric welding operation process on the market can only play the protective action to electro-welding arc and baking mostly, and a large amount of smog, micronic dust and harmful gas that electric welding field is produced almost do not have protective action.Under such environment, work for a long time, electric welding field personnel's respiratory system is caused great harm, as pneumoconiosis, respiratory tract disease etc.
Summary of the invention
The purpose of this utility model is exactly in order to provide a kind of simple in structure and keeping on the basis of former electric welder's helmet effect the self-priming air cleaning electric welding protective mask that can carry out effective respiratory protection to flue dust and harmful gas.
Goal of the invention of the present utility model is achieved in that a kind of self-priming air cleaning electric welding protective mask, include protective mast and the oronasal mask that is installed in the face shield inboard, airway, compositions such as gas purification filter chamber, the gas purification filter chamber that connects by airway and oronasal mask is placed in the inboard top of face shield, in the gas purification filter chamber changeable type is installed and crosses filter element, two inlet valves and an outlet valve are housed on the oronasal mask of protective mast inboard, left and right sides inlet valve UNICOM about the gas filtration clean room passes through on two airways and the oronasal mask, and inlet valve and outlet valve are check valve, and wherein the material of filter element can adopt dustproof, protection from fumes, the material of kinds such as gas defence.
Smooth and easy in order to guarantee that operator breathe, the channel diameter of outlet valve is greater than the inlet valve channel diameter.
The protective mast top of this device curves inwardly; damages such as the spark that the inboard gas filtration chamber of protection is not spilt, welding slag; the nose and mouth of face shield are to outer lug; guarantee certain placement space for the oronasal mask of protective mast inboard; in the upper end of face shield inboard and the position, both sides of the edge of lower end two bracelets are arranged respectively; can connect two with frenulum, be enclosed within head and cervical region is used for fixing protective mast.
The protective eye lens of this self-priming air cleaning electric welding protective mask comprises transparent glasses lens that is embedded on the face shield and the filter lens for arc welding composition that is embedded in the upset picture frame, the screening glass that can open the outer end in the gap of electric welding field sees through interior eyeglass and watches, and will not take off by face shield.
The beneficial effects of the utility model are, this apparatus structure is simple, and cost is low; on the protective action of electric welder's helmet basis; can effectively improve the air-breathing quality of electric welding field personnel when work, protect the healthy of electric welding staff, reduce the generation of electric welding staff occupation disease.
