Benefits of technology
The present invention provides an improved air supply device and method for creating a natural environment in a partially enclosed helmet, such as a welding hood. The device includes a housing containing a blower, a filter, a partially bifurcated air supply member, a power source, and a circuit board. Turbulent air enters the housing through the filter and continues into the blower, which pushes the air through the air supply member. The bifurcated air flow is then expelled from the device in two thin sheets of laminar air, creating a smooth and natural air flow. The device can be secured to protective headgear with a clip or a clip and an inner cavity. The patent also describes the features of the air supply device, such as the at least two openings and the guiding of the turbulent air into the blower.
Problems solved by technology
Several problems exist for users while wearing a welding hood, such as high temperatures within the welding hood, exposure to toxic fumes, and fogging of the lens.
Secondly, the hose, cap, and fan configuration cannot be easily adjusted during use and poses a safety risk, as the hose can get caught on objects without the user being fully aware of the hose's positioning.
None of these known air supply systems for welding hoods, however, adequately resolve the issues of overheating within the welding hood and fogging along lens or other similar structures through which the user looks.
This merely pushes fumes towards a user's face.
A sealed hood with an air supply member also tends to increase pressure within the welding hood and on the user's head.
Even with a constant supply of new air, the air mass in the welding hood eventually heats up and cannot escape fast enough to prevent a humid environment within the hood.
In addition to this, exhalation from the user's mouth and nose, next to the lens, create significant fogging.
The inventors have found that an air supply from the back of the user's head is simply insufficient to resolve the outstanding issues in the art regarding air supply systems for welding hoods.

An improved air supply device that is removably securable within a welding hood or similar helmet structure. The air supply device provides two thin sheets of smooth, directed air within the hood. One sheet is directed toward a lens to provide a barrier to humidity. The other sheet of air is provided back toward a user's face to provide a barrier to external fumes and to cool the user. The air supply device is designed to smooth turbulent air flow through multiple structures so supply laminar sheets of air flow within the welding hood to recreate a natural environment for the user.
