Description

Dust and gas masks {GOGGLE FOR ANTI-DUST AND ANTI-GAS}

The present invention relates to a goggles for dust and gas, especially the goggles are worn so that the nose portion is located inside the goggles so that the intake of the breath through the inside of the goggles and the exhaust of the breath through the mouth and from the outside of the goggles Fresh air or fresh air filtered with dust or toxic gas is introduced, and the fresh air or filtered air is introduced to the dust and goggles safety glasses for preventing the steam on the inner surface of the safety glasses.

In order to protect the eyes from the conventional working environment and to prevent inhalation of dust or toxic gas during breathing, the nose part of the worker is worn to be placed in the safety goggles. There is a flaw that causes obstruction of the worker and interferes with the work of the worker. In addition, in the case that the filter device is integrally configured for dust or gas, the projecting structure of the filter device narrows the operator's field of vision, which may impede the worker's work activity. In addition, having a means for forcibly supplying air for breathing into the safety glasses has a drawback that is not only complicated in construction but also expensive in manufacturing.

In the present invention, in view of such a conventional point of view, the safety goggles of the structure covering the nose of the worker to allow the fresh air or filtered air to enter the safety goggles during inhalation of the worker breathing, and inside and outside the safety goggles This inflow of fresh or filtered air at the same temperature as the ambient temperature prevents fog on the inner surface of the sight glass of the eye shield, and at the end of the air supply for supplying fresh or filtered air into the eye shield. The purpose of this is to connect the easy-to-use filter can be dustproof and anti-gas.

To this end, in the present invention, a transparent viewing window is attached to the front of the hood that can cover the eyes and nose of the worker and is worn on the head of the worker so as to extend from both sides of the hood so that the hood can be closely attached to the face of the worker. To provide a pair of safety glasses. An intake pipe extending from the outside to the inside of the hood near the viewing window is installed on the upper side of the hood, and the intake pipe extending from the filter can be carried by being detachably fixed to the waist belt of the operator or carried in conjunction with the band of the hood. Connect to the outer end of the

A transparent viewing window 12 is attached to the front of the hood 10, which is sized to cover the eyes and nose of the worker, and extends from both sides of the hood 10 so that the hood 10 can be closely attached to the face of the worker. In the band 14 worn on the head of the worker is coupled, the intake pipe 16 extending from the outside to the inside in close proximity to the see-through window 12 on the upper side of the hood 10 is installed, and on the bottom in the form of a container. The intake hose 28 extending from the filter cylinder 26 in which a plurality of air supply holes 18 are formed and a permeable sponge layer 20, a microfiber layer 22, and an activated carbon layer 24 is filled therein is provided. It is a structure that can be connected to the outer end 30 of the intake pipe 16.

The present invention is such that the operator facing the sight window 12 to the front so that the hood 10 is in close contact with the face so as to cover their eyes and nose portion, wearing a band on their head using a filter 14 (26) can be detachably fixed to the waist belt (32).

The worker inhales and exhales through his nose for breathing. At the time of inhaling the nose, outside air is introduced into the inside of the safety glasses, that is, the hood 10 and the sight glass 12, and the inside of the face, through the intake pipe 16. Thus, the worker can inhale through the nose and breathe out through the mouth. Outside air flowing into the intake pipe 16 is absorbed with the filter cylinder 26 in a state in which dust or toxic gas is filtered through a filter cylinder 26 fixed and carried by the worker's own waist belt 32. It is supplied through an intake hose 28 connecting the engine 16. When the worker inhales during inhalation, the intake pressure is transmitted to the filter cylinder 26 as a negative pressure so that external air passes through the air supply holes 18 of the filter cylinder 26, and the sponge layer 20 and the microfiber layer are substantially filter media. (22) and the activated carbon layer 24 is introduced, and in this process, the dust or toxic gas contained in the air is filtered and filtered fresh air is supplied into the safety glasses. Furthermore, since the air has an ambient temperature around it, when it enters the safety glasses, the inside and outside surfaces of the see-through window 12 are the same, so that the air is temporarily vented through the nose when breathing, causing steam to swell in the see-through window or sweat from the worker's face. This prevents the steam from frosting on the sight glass.

For example, it has been described that the filter barrel 26 is composed of a sponge layer 20, a microfiber layer 22 and an activated carbon layer 24 as a filter medium, but such a filter medium has a composition or composition as necessary. It may vary.

In addition, the operator can use the filter can be combined with the band 14 connected to the hood 10 as it is or miniaturized. In such a case, the length of the intake hose 28 connecting the filter cylinder 26 and the intake pipe 16 is short, and it is easy to carry even with low intake force, and it is easy to carry. .

On the other hand, the operator can use the intake pipe 16 formed in the hood 10 of the safety glasses worn by the operator without using the filter cylinder 26 to the external forced air supply means. As the forced air supply means, an oxygen cylinder or a blowing fan may be used.

As such, the present invention allows the fresh air or filtered air to be introduced into the safety goggles during inhalation of the worker in a wide goggles covering up to the nose of the worker. The inflow of air or filtered air prevents steaming on the inner surface of the sight glass of the safety glasses, and is easily dustproof by connecting a portable filter can to the end of the air supply pipe for supplying fresh or filtered air into the safety glasses. It is to provide safety goggles to work safely and efficiently when working in a place where the environment is poor by allowing gas and gas.
