Description

A dust-proof and arc-proof dual-purpose helmet and using method thereof

technical field

The invention relates to the technical field of labor protection appliances, in particular to a dust-proof and arc-proof dual-purpose helmet and a method for using the same.

Background technique

In mining, metallurgy, construction, mechanical cutting and welding and other operating environments with a large amount of dust, workers work in conditions with severe dust and other pollution for a long time. Because they cannot breathe clean air for a long time, it will cause great harm to health. Therefore, appropriate dust respirator must be worn.

At present, the existing dust-proof respirator on the market has the air outlet set on the side of the cheek. It seems that the air flow path is short and the air outlet effect is direct. will be affected. In addition, the dust-proof respirator currently on the market only has a single function of dust-removing and air-supplying, and the air-supplying device is bulky, consumes a lot of power, and is inconvenient to use.

Sometimes electric welding is also performed during construction operations. For safety reasons, workers will use masks for protection during the welding process. The existing protective masks for electric welding are mainly hand-held masks and head-worn masks. The handle of the hand-held mask is fixed by two screws, and the screws are easy to fall off during long-term operation. When using a hand-held mask, it is difficult to carry out other tasks with the mask in one hand and the welding tongs in the other. When using a head-worn welding mask, workers may take off the mask and look at the welding points before working, which is very inconvenient to put on and take off.

It is very necessary to design a product that can not only play a dustproof effect but also play a protective effect during the welding operation.
