Portable manual arc welding gas defense and dust prevention welding mask

Abstract

The invention discloses a portable manual arc welding gas defense and dust prevention welding mask, and relates to the technical field of welding masks. The welding mask aims to solve the safety problem of the welding mask. The welding mask specifically comprises a mask body, rotating bases are connected to the outer walls of two sides of the top of the mask body in a threaded manner, the outer walls of the two sides of the two rotating bases are connected with magnetic attraction blocks through mounting nuts, the outer walls of the opposite sides of the two magnetic attraction blocks are attracted with the same helmet, an observation hole is formed in the outer wall of the front face of the mask body, the outer walls of the two sides, close to the observation hole, of the mask body are fixedly provided with the same arc-shaped mounting plate through two round snap-fasteners, a clamping groove is formed in the outer wall of the front face of the arc-shaped mounting plate, the inner wall of the periphery of the clamping groove is connected with the same goggles in a clamped mode, and dust prevention filters are arranged on the outer walls of two sides of the front face, close to thelower portion of the goggles, of the mask body. According to the welding mask, sucked gas can be effectively subjected to dust filtering and disinfection through a dust prevention disinfection mechanism, so that the air sucked by a user does not contain toxic dust.

Description

technical field [0001] The invention relates to the technical field of welding masks, in particular to a portable manual arc welding anti-virus and dust-proof welding mask. Background technique [0002] A welding mask is a tool used to protect the safety of workers during welding and cutting operations. It is a high-tech product integrating optics, electronics, human body, materials and other disciplines. High-quality LCD and glass-coated combination are used as shading lenses. The light sensing system on the lens can instantly detect the generation and disappearance of arc light during electric welding, and quickly drive the liquid crystal to shading and change color to achieve safe and effective filtering of harmful light, thereby protecting welders. Eyes, face to avoid arc radiation damage. [0003] After retrieval, the Chinese patent application number is CN201520397374.1, which discloses a mouth-held welding mask, which belongs to the field of welding appliances. A m...

Problems solved by technology

[0004] Although the overall device achieves the most basic function of the welding mask, during the arc welding process, due to the burning of materials, toxic dust will be generated in the air. Once the user inhales such dust for a long time, it will cause the user to get sick. Therefore, , there is an urgent need for a portable manual arc welding anti-virus and dust-proof welding mask
