Abstract

The invention relates to digital automatic light changing welding goggles. The digital automatic light changing welding goggles comprise a shell, a lens set and an internal circuit, wherein the internal circuit comprises a single chip microcomputer minimum system (1), a power circuit (2), an electric arc detection circuit (3), an environment temperature detection circuit (4), an LED display circuit (5), a microcomputer switching circuit (6), a liquid crystal drive circuit (7), a sensitivity selection circuit (8), a keying circuit (9) and a five-voltage-multiplying generating circuit (10). When the environment temperature is lower than 0 DEG C or higher than 40 DEG C, compensation can be conducted on shade number automatically. By means of the single-chip microcomputer technology, a good human-computer interaction platform can be provided for a user, and humanization and intelligentialize can be achieved.

Description

technical field [0001] The invention belongs to the field of electronic devices and relates to a digital automatic darkening welding goggle, especially when the ambient temperature reaches below 0°C or above 40°C, it can automatically compensate the shading number. The use of single-chip microcomputer technology allows users to have a good human-computer interaction platform. Background technique [0002] There are many hazards caused by arc welding arc light, especially serious damage to the eyes. Welding goggles are a special sharp tool to prevent and control the arc light hazards of arc welding. The shading number of electric welding goggles appearing on the market is not adjustable, and can only be changed by changing the lens. At the same time, the removal of the lens will cause a certain degree of scratch to the lens, which is very inconvenient for the user. [0003] Around the welding goggles, the designers have proposed welding goggles with automatic dimming, autom...
