Description

Technical Field

[0001] The invention relates to the technical field of tools for painting, in particular to a gas-proof helmet mask. Background Art

[0002] Spray painting technology has long been popularized in both industrial and civilian use, especially in the industrial field, where most industries have achieved automated and systematic operations. However, no matter how advanced the spray painting system is, it will generate a large amount of paint mist (toxic gas) during the spray painting process. To deal with this problem, the traditional solution is usually to slowly remove the generated paint mist by exhausting and changing the air, and to let the operator wear an ordinary mask during the exhaust and change of air to prevent the operator from inhaling a large amount of paint mist. It is well known that although this solution can reduce the operator's inhalation of paint mist and toxic gas, it cannot effectively prevent the operator from inhaling paint mist and toxic gas. The paint mist generated at the spray painting site will still have a serious impact on the operator's health. Summary of the invention

In this way, the wearing, use and removal of the gas helmet mask can be achieved by moving the mask. When the gas helmet mask needs to be worn on the head and face of the operator for gas-proof breathing, the mask is translated so that the mask is located below the helmet. At this time, the mask will cooperate with the bottom of the clean air delivery structure arranged on the helmet to be sealed and connected, and then the clean air delivery structure delivers clean air for the operator to breathe, and the exhaust gas is discharged through the one-way valve on the breathing mask, which can effectively prompt the operator to breathe fresh and clean air and effectively prevent the operator from inhaling exhaust gas and poisonous gas.

Figure 1-Figure 4 As shown, in this embodiment, the gas helmet mask includes:

[0049] Helmet 1;

[0050] The mask 2 is arranged below the helmet 1 and can be translated below the helmet 1. When translated to outside the projection range of the helmet 1, the mask 2 can be flipped upward and detachably connected to the helmet 1.
