Description

Technical Field

[0001] The utility model relates to the technical field of welding masks, in particular to a portable welding mask. Background Technique

[0002] At present, there are two types of welding masks for construction. One is the traditional handheld and head-mounted masks, and the other is the head-mounted integrated automatic dimming mask using photosensitive materials. When using the traditional welding mask, the welder needs to fix it with one hand or use a hoop to fix the mask on the head. The viewing frame of the mask is sequentially installed with a white glass and a black glass from the outside to the inside, and the viewing frame cannot be opened or closed. When observing the weld formation and stopping the welding operation, the welder needs to remove the mask or lift the mask to perform the next operation. This traditional welding mask has great limitations when welding in difficult positions and narrow positions. When wearing and lifting some head-mounted masks, the safety helmet needs to be temporarily removed, which poses a safety hazard.

[0003] The viewing frame of the head-mounted automatic dimming mask uses a dimming and filtering lens. At the moment when the electric arc is generated, the light inside the mask changes from bright to dark, which can better protect the welder's eyes. However, on the one hand, the wear resistance of this mask is poor and it is easy to be damaged in the welding environment of difficult positions and harsh conditions. On the other hand, the cost of this mask is high and the procurement cycle is long. When configured in large quantities for construction, its economic characteristics are not obvious. There is a need for a portable welding mask to solve the above technical problems. Content of the Utility Model
