The respiration full face mask has the beneficial effects that hard light of electric arc is prevented from damaging eyesight of human eyes; electromagnetic waves, such as ultraviolet rays and infrared rays generated by electric arc during welding are prevented from generating harmful radiation on human bodies; welding splash or impurities can be prevented from hurting faces, and the occurrence of skin burning diseases is reduced; damage to the respiratory system of a human body caused by poisonous and harmful gas, dust and the like discharged during welding is reduced, and the occurrence rate of pneumonoconiosis occupational diseases is reduced; and the condition that when operating personnel break, observing sight line of the operating personnel is obstructed by the welding lens so as to influence the welding quality of workpieces is avoided.
Description
Technical field
The utility model relates to a kind of protective device, relates in particular to a kind of respiratory system protective device.
Background technology
At present; breathing mask is widely used in the every field such as fire-fighting and rescue, metallurgy, chemical industry, boats and ships and army as respiratory protection equipment, make the fireman or speedily carry out rescue work that the rescue personnel can put out a fire safely under the adverse circumstances that are full of dense smoke, poison gas, steam or anoxic, rescue and relief work and rescue.The operation principle of breathing mask is to utilize extraneous source of the gas to enter breathing mask, breathes for the wearer, and protection user respiratory apparatus is not subject to the infringement of poisonous and harmful surrounding air.Usually breathing mask be furnished with afford a wide field of vision, become clear, airtight good face shields and the extraneous source of the gas that is equipped with small volume, lightweight, stable performance and holds time and grow, so that the wearer can work in the fatal atmosphere environment or implement rescue action.
Along with the progressively application of new technology in respiratory protection equipment field; the breathing mask that originally only has the respiratory protection function is derivatized out increasing other functions; for example; some breathing masks possess can detect external environment air poisonous and harmful whether function; dehumidification function, or the function of early warning air feed surplus.Have the breathing mask of these functions when satisfying respiratory protection, increased again wearer's practicality, security and comfortableness.
In the industrial operation environment, especially when implementing weld job, working environment is often more abominable, and the electromagnetism swash such as the ultraviolet ray that electric arc produces and infrared ray can form harmful radiation and eye is caused great injury the operator; The spatter thing that produces in operation process can cause infringement to operator's face; Simultaneously, the harmful poisonous gas that discharges during welding and dust also can consist of damage to operator's respiratory system.Therefore, each side wishes to obtain a kind of breathing mask of multiple function that integrates to tackle work production environment complicated and changeable.
The utility model content
The purpose of this utility model is to provide a kind of breathing full facepiece mask; this breathing full facepiece mask is when satisfying respiratory protection; can avoid the user not to be subjected to the infringement of intense light and harmful radiation when welding, can prevent that again spatter thing and dust are to its injury facial and respiratory system causes.
In order to realize above-mentioned purpose, the utility model provides a kind of breathing full facepiece mask, and it comprises: face frame and the face that is embedded in the face frame shield, and described screen is provided with intake interface; In addition, described screen has a window area; One welding lens, itself and described frame are flexibly connected, and shield the position of corresponding window area, the outside or leave this position to be located at face with switching.
Breathing full facepiece mask of the present utility model is provided with the welding lens that is flexibly connected with the face frame on the design basis of existing breathing mask, and this welding lens is arranged on the outside of face screen.The upper zone that covers user's eye of face screen is the window area, and the operator can observe workpiece or welding situation by the window area, and the welding lens switchable type ground of this flexible connection is in the position, window area or leaves the position, window area.When welding is carried out, thereby the operator makes welding lens eyeglass filter the welding high light to ocular with whole overwrite job persons' eyes to avoid human eye to be subject to ultraviolet ray and ultrared radiation that electric arc is produced along outer being sidelong of face screen, and welding lens is in the position, window area at this moment.When welding was ended, the operator pushed away welding lens the observation sight line that can not affect the operator until welding lens breaks away from ocular fully outside the face screen, and this moment, welding lens left the position, window area.Be connected with extraneous source of the gas air guide by intake interface owing to breathing full facepiece mask, make pernicious gas and dust in operating personnel and welding surroundings isolated, can breathe all the time air clean, cleaning in the welding job process; Simultaneously, the face screen of breathing full facepiece mask also can prevent impurity dying in spatter thing and welding air to the infringement of operating personnel face and burn.
Further, welding lens and the face frame in breathing full facepiece mask described in the utility model is hinged.
Further, breathing full facepiece mask described in the utility model also comprises a headband, and the two ends of this headband are connected to the both sides of described frame.Breathe full facepiece mask to the pressure of head in order to alleviate when welding stops, the operating personnel can unload from its face breathing full facepiece mask, and only relies on the support of headband that full facepiece mask is hung on neck.
Further, breathing full facepiece mask described in the utility model also comprises a net, and this net is connected with described frame by a pair of connecting band at least.Online connecting band can be regulated the tightness between face shield and head.
Further, breathing full facepiece mask described in the utility model also comprises an air inlet pipe, and it is connected with described intake interface.Intake interface is connected with air inlet pipe in order to the fresh air that comes from source of the gas is provided to the operating personnel, and this source of the gas makes to breathe in full facepiece mask and remains malleation.
Compared with prior art, breathing full facepiece mask described in the utility model, due to the welding lens that is provided with flexible connection, its advantage that possesses is as follows:
1) prevent that the electric arc high light is to the injury of human eyesight;
The electromagnetic waves such as the ultraviolet ray that when 2) avoiding welding, electric arc generates and infrared ray produce harmful radiation to human body;
3) isolated spatter thing or impurity cause infringement to face, reduce the generation of skin burn disease;
The toxic and harmful that discharges when 4) reducing welding and dust etc. reduce pneumoconiosis occupational disease odds to human respiratory institute injury;
When 5) avoiding work intermittently, welding lens hinders operating personnel's observation sight line and affects the workpiece welding quality.
