Description

Technical Field

[0001] The utility model belongs to the technical field of welding mask equipment, and particularly relates to a dust-proof and smoke-proof welding mask. Background Art

[0002] A welding mask refers to a tool that protects the safety of operators during welding and cutting operations. The handheld welding mask is the most traditional welding mask, which is mainly composed of a mask body and a handle. During the welding operation, it is necessary to hold the mask with one hand and the welding torch with the other hand. However, in some environments such as where the workpiece needs to be held by hand or in high-altitude operations, the operation will be very inconvenient, and there are also great safety hazards.

[0003] In order to solve the deficiencies of the existing technology, people have carried out long-term explorations and proposed various solutions. For example, a Chinese patent document discloses a dust-proof and arc-proof dual-purpose helmet and its use method [202010192037.4]. The helmet includes a helmet body, a transparent dust-proof mask, an arc-proof mask, and a respirator. The dust-proof mask is hinged to the helmet body, the arc-proof mask is hinged to the dust-proof mask, and the respirator is connected to the helmet body through a first air duct; a second air duct is installed inside the helmet body, the air inlet of the second air duct is communicated with the first air duct, and the air outlet of the second air duct is aligned with the inner side of the dust-proof mask.

[0004] The above solution solves the problems of inconvenient operation and safety hazards brought by the existing handheld welding mask to a certain extent, but there are still many deficiencies in this solution. For example, the welding mask cannot wrap key parts such as hair and neck. Summary of the Invention
