Video welding mask

Abstract

The invention provides a video welding mask (1). The video welding mask comprises a mask main body (10), a camera (30), a display (40), a lithium battery, a filter lens (24), a polarized lens A (11),a polarized lens B (22), a transparent lens (21), a gasket (23) and a lens cone (20). The camera (30) is mounted at a small hole of a boss (13) on the mask main body (10), and the display (40) is mounted inside the mask main body (10); the lithium battery is integrated with the display (40) and supplies power to the display; the polarized lens A (11), the filter lens (24), the gasket (23), the polarized lens B (22) and the transparent lens (21) are sequentially mounted outside the camera; the lens cone (20) is mounted on the boss (13); and the polarized lens B (22) and the transparent lens (21) are sequentially and fixedly mounted in the lens cone (20) from the direction close to the mask main body (10).

Description

technical field [0001] The present application relates to the field of welding protection, in particular to a welding mask. Background technique [0002] At present, known welding helmets are composed of observation windows, optical filters, protective sheets and face shields. There are regular non-dimming masks and auto-dimming masks. [0003] Ordinary non-mutable light masks filter and weaken harmful light and strong light generated by welding by dark lenses. The larger the lens number, the darker the color, the better the protective effect, but the worse the visibility. The smaller the lens number, the lighter the color, and the worse the protective effect. The color of the lens is not adjustable for the same mask. During the welding process, especially with current welding, the light intensity produced by different currents is different, and sometimes the use effect is relatively poor. For safety protection, relatively large lenses are generally used, and the use exp...

Problems solved by technology

Moreover, the quality of automatic darkening masks on the market is uneven. The price of high-quality basic foreign manufacturers is particularly expensive, and the low-quality ones cannot achieve the protective effect. Relatively few automatic darkening masks are used in China.

[0005] The basic principle of ordinary non-variable and automatic darkening masks is to pass harmful light through dark lenses, and remove the dimming delay problem of automatic darkening masks, harmful light cannot be completely filtered, and it is impossible to completely avoid welding work. injury

[0006] In summary, the protection and visibility of masks in the existing market are relatively poor

In addition, it is not particularly convenient to adjust for different needs
