Description

Nose guard for welding work with protect function for automobile production

Technical Field

The invention relates to the field of welding protection tools, in particular to a nose guard for a welding tool with a protection function for automobile production.

Background

Welding, also known as fusion welding, is a manufacturing process and technique for joining metals or other thermoplastic materials, such as plastics, in a heated, high temperature or high pressure manner, and there are many processes that need to be applied to welding techniques in the automotive production process, and modern welding uses a wide variety of energy sources, including gas flame, electric arc, laser, electron beam, friction, and ultrasonic, among others. In addition to use in a factory, welding can be performed in a variety of environments, such as the field, underwater, and space. Wherever welding can be dangerous for the operator, appropriate precautions must be taken while welding is being performed. The possible injuries to human body caused by welding include burn, electric shock, visual impairment, toxic gas inhalation, over-irradiation of ultraviolet rays, etc.

The inside of the nasal cavity of a mammal is generally covered with the vibrissa, the vibrissa has a certain protection effect, on one hand, large-particle impurities can be prevented from entering the body through the nasal cavity, on the other hand, the nasal cavity can be used for adsorbing partial toxic gas or powder through gland-sealed viscous liquid, and the influence of the toxic gas and small-particle powder gathered in the external environment is reduced.

The traditional welding protection device is a simple mask, welding work can be normally carried out on the premise of not influencing the normal work of technicians, but the simple mask has limited protection effect, generally, the technicians can only be protected from being damaged by sparks generated in the welding work, the influence of strong light generated in the welding process on the eyesight of the technicians can be effectively relieved by lenses arranged on the simple mask, the protection effect on toxic gas generated in the welding process is very little, although the mask can partially shield smoke from flowing to the technicians, when the welding work is carried out for a long time, the toxic gas is very easy to be gathered at the position of the welding work in a large amount, physiological damage is easily caused to the technicians, although a special mask has a certain protection effect, the welding work environment is relatively severe, and if the mask is used for a long time to shield the mouth and the nose, a reaction of unsmooth breathing can be generated, particularly, the heat stroke of technicians is easily caused in a partially sultry environment.
