As shown in fig. 2, the observation eyepiece 9 includes a frame and two lenses mounted on the frame, the two lenses are an objective lens having an amplifying effect and a field lens capable of making the influence highly uniform, the objective lens and the field lens are arranged at intervals, and the field lens is closer to the liquid crystal display.
The electric welding mask also comprises an illuminating lamp 6, wherein the illuminating lamp 6 is arranged on the outer side face of the mask main body 1 and is positioned right above the liquid crystal display 8, and the illuminating lamp 6 is electrically connected with the photovoltaic cell panel 21 and the storage battery 222; the control buttons further include a lamp control button 74, and the lamp control button 74 is electrically connected to the lamp 6.
In this embodiment, the welding helmet further includes a hinge 12 and a head band 13, where the hinge 12 connects the head band 13 and the helmet body 1, so that the helmet body 1 can rotate relative to the head band 13 to be worn by a user, and compared with a hand-held helmet, the welding helmet can release the hands of the user, so that the hands can cooperate and coordinate with each other.
The invention displays the images before and during the electric welding on the liquid crystal display screen in real time through the two camera devices without direct observation by human eyes, thereby avoiding the damage of harmful arc light caused by direct vision of the arc by the human eyes, and in particular:
the image before electric welding and during arc striking can be clearly shot through the flat light camera device 4, an operator can check the position of the welding spot in time through the image, and the position deviation of the welding spot during arc striking operation is avoided;
the speed, the direction and the state of a molten pool of the strip during welding operation can be clearly observed through the optical filtering camera device 5, so that the welding quality is better ensured;
the liquid crystal display screen 8 can present images shot by the two camera devices in real time, and can realize free switching of double-screen and single-screen display; because the arc striking process is short in time and can emit infrared rays, ultraviolet rays and high-intensity visible light, an operator can conveniently operate the arc striking step during double-screen display, and the arc striking and strip conveying steps are smoothly transited;
the photovoltaic cell panel is a semiconductor material, has a wider band gap, and can convert all light energy from ultraviolet light to infrared light in electric welding arc light into electric energy; the charge-discharge control circuit board 223 can regulate and control the charge and discharge of the photovoltaic cell panel 21 and the storage battery 222 in real time according to the generated energy of the photovoltaic cell panel 21 and the power consumption of the equipment. Meanwhile, after working, the electric welding mask is placed under the sun for shining and generating electricity, the generated electricity can be used for electric appliances such as mobile phones, mini fans and the like, and the storage battery 222 can be charged through commercial power, so that the electric welding mask can be used as a mobile power supply.
The foregoing description is only illustrative of the preferred embodiments of the present invention, and therefore should not be taken as limiting the scope of the invention, for all changes and modifications that come within the meaning and range of equivalency of the claims and specification are therefore intended to be embraced therein.
