Description

Air Cooled Solar Welding Helmet

technical field

The utility model relates to an air-cooled solar welding mask used in the welding process, which is particularly suitable for labor protection equipment used in a closed environment or an environment with poor ventilation conditions.

Background technique

At present, most welding protective masks are hand-held, which consists of a mask shell, a protective lens, and a handle. During welding, the operator holds the handle at the lower part of the mask to cover the face, so as to protect the operator's face from the arc light, and remove the face when the welding is over, so as to facilitate observation and other operations. Because one hand is always required to hold the mask during the welding process, the operator's work intensity and difficulty are greatly increased, and various actions during the welding process cannot be well coordinated, especially when welding small workpieces. Effective positioning will affect welding quality and welding efficiency.

The other is to wear a manual welding mask. The welding protective mask is equipped with a headband device with adjustable elasticity, which is convenient to wear on the head. The protective lens is opened and closed manually. When welding, close the protective lens on the window to protect the eyes. , When not welding, open the protective lens for easy observation. Because it requires frequent manual opening and closing of the protective lens to achieve the protective effect, it is inconvenient to operate, especially when welding small workpieces, which may affect the quality and efficiency of welding operations.

Most of the new products developed at home and abroad are light-sensing welding masks. This kind of mask collects the welding arc generated during the welding process as a control signal, controls the change of the light transmittance of the liquid crystal panel installed on the viewing window, and realizes the welding arc. Obstruction and protection of the operator. Because the liquid crystal always changes after the welding arc is generated, so before the liquid crystal turns black, there will always be a part of the arc light that has passed through the liquid crystal and hurt the operator's eyes. It is difficult to achieve the required blackness in time, and it is inconvenient to replace the liquid crystal sheet.

In addition, during the welding operations of ships, pipelines, and pressure vessels, the ventilation conditions are poor; during the construction of gas shielded welding, the protective gas dilutes the oxygen in the air, which affects the breathing of welding operators. It affects the quality of gas shielded welding and affects the construction effect. Moreover, because the general welding operation is relatively scattered, it is unreasonable to use global gas supply, resulting in energy waste. When there are multiple groups of operations in the workshop, it is impossible to ensure that all welding operators can breathe cleanly. Air.

Contents of the invention

The purpose of this utility model is: in order to provide reliable breathing air for a single welding operator during welding operations in a closed environment or an environment with poor ventilation conditions, and prevent the welding operator from being hypoxic or inhaling harmful smoke and dust during construction, a special proposal is made. An air-cooled solar welding helmet.

In order to achieve the above purpose, the technical solution adopted by the utility model to solve this technical problem is: an air-cooled solar welding mask, which is composed of a mask shell, a solar panel, a ventilation assembly and a ventilation pipe joint, and is characterized in that: The mouth and nose position of the face mask shell is plastic injection-installed with a ventilation assembly and a ventilation pipe joint. The bottom of the joint is slightly larger and is used to install a miniature axial flow fan; the ventilation assembly is composed of a miniature axial flow fan, a ventilation sheet, and a filter pad. It is fixed on the bottom surface of the ventilation pipe joint. The suction end of the miniature axial flow fan is pressed against the edge of the filter pad, and the discharge end is facing the mouth and nose. The ventilation sheet is installed on the inner surface of the mask to limit the movement of the miniature axial flow fan in the axial direction. A group of ventilation holes are processed to form the entity of the ventilation sheet; the solar panel is installed above the ventilation pipe joint at the lower part of the mask shell, and is connected to the contact point of the miniature axial flow fan by a set of wires, or a rechargeable battery is used, and a set of wires Connect the solar panel to the rechargeable battery, and then connect the rechargeable battery to the miniature axial flow fan. The filter pad is installed at the suction end of the miniature axial flow fan. The breather connector is connected to a long breather hose.

The utility model installs a ventilation function module on the basis of the existing welding mask, and provides effective air supply for welding operators when some ventilation conditions are poor, gas shielded welding, and scattered welding operations. The miniature axial flow fan installed on the welding mask works under the power supply of solar panels, or the solar panel supplies power to the rechargeable battery, and then the rechargeable battery supplies energy to the miniature axial flow fan. One end of the long ventilation hose is connected to the ventilation pipe joint, and the other end is extended into the external fresh air, and the fresh air outside the welding workshop or workplace is transported into the inside of the welding mask to supply the welding workers to breathe, and at the same time play a role in cooling.

The beneficial effects of the utility model are: the miniature axial flow fan installed on the welding mask is powered by the solar battery, and the fresh air is delivered into the welding mask through the long ventilation hose to supply the breathing of the welding operator, which reduces the labor intensity and is beneficial Improve labor efficiency and work quality. The welding mask has the advantages of simple structure, energy saving, automatic safety, and is mainly used for welding operations in a closed environment or an environment with poor ventilation conditions.
