Description

Mask for supplying oxygen and protecting dust}

The present invention relates to a work hood for use in a harsh working environment, and more particularly, a safety helmet fixing net is mounted on the upper surface of the hood worn during work in the workplace, and can be used by exchanging hard hats of various sizes according to the head size of the worker. And a work hood configured to allow the hard hat to be removed.

Typically, in a poor working environment, for example, sanding, dusting, dustproofing, painting, painting the bottom of the ship, coal mining, and excavation of the tunnel will be insufficient oxygen during the operation, preventing In order to do this, the operator must wear a work hood on his head. The work hood also protects the operator's head as well as oxygen supply and prevents ingress of dust, toxic gas particles and other foreign matter.

Conventional working hood that performs the above function is largely composed of a hard hat, hood cover and sight glass. Conventional working hood is formed so that the cover is formed of a forge material and covered from the helmet to the lower part of the shoulder of the worker and the helmet is fixed with a rivet inside the hood. In addition, an endothelial to support the head of the worker is installed inside the hard hat, and the purified air hose is fixedly installed in a state where a plurality of holes are formed on the upper side of the endothelial. The air hose installed in the conventional working hood receives oxygen from the oxygen cylinder and supplies the inside of the hood. And, the front of the conventional work hood is fixed to the viewing window to allow the operator to observe the outside.

However, in the conventional working hood, since the cover is attached only to the upper end of the hard hat, the hood cover flows from the hard hat, and the sight window installed on the hood cover is not only flowed left / right, up / down, but the sight window is twisted from side to side. As a result, the front view of the worker cannot be secured, causing inconvenience to the work, and a problem arises in which an emergency situation cannot be dealt with promptly.

In addition, the conventional working hood has a hole in the hard hat and a plurality of screws, pins or rivets are covered in a fixed state by combining the hard hat and the hood, so it is impossible to replace the hard hat or very uncomfortable, which takes a lot of replacement time. There is this. In addition, the conventional work hood is drilled in a hard hat and covered with a plurality of screws, pins, or rivets, so that the hard hat is broken or damaged when a hard impact is applied to the hard hat. There was a problem. In addition, the conventional work hood causes workers to cause respiratory diseases due to the adhesion of dust, toxic gas particles and other foreign matter in the gap of the hood cover.

The purpose of the present invention is to provide a work hood that is equipped with a hard hat fixing net on the upper surface of the work hood to cover and fix the hard hat, to enable the exchange and detachment of the hard hat, and to prevent the flow of the hood cover and the flow phenomenon of the sight glass. Is in. Since the work hood of the present invention does not drill holes for using rivets on the hard hat itself or drill holes for inserting purified air hoses, the hard hat itself has strong impact resistance and safety that may be caused by a strong impact on the hard hat when using the hard hat. The risk of an accident can be prevented. In addition, the work hood of the present invention is easy to manufacture the hood because the rivet is not used in the state of drilling a hole in the hard hat itself or a combination of the hard hat and the hood.

The present invention for achieving the above object is a hood cover 10 to be covered with a hard hat for protecting the head of the operator and the lower part of the face and shoulders; A hard hat fixing net 20 attached to an upper portion of the inner surface of the hood to cover and fix the hard hat and to exchange and detach the hard hat; It provides a working hood consisting of a viewing window 30 mounted to the front of the hood for the operator to observe the outside.

Working hood of the present invention is characterized in that the endothelial 40 is mounted on the lower inner surface of the hood so as to surround the lower portion of the neck, characterized in that the hose 50 for supplying purified air into the hood.

Working hood of the present invention is a hood that works while supplying purified air inside the hood. The air supplied during the operation while wearing the working hood of the present invention is purified air and contains oxygen. The work performed while wearing the hood of the present invention includes sanding, dusting, dustproofing, painting and dusty work. If a worker wants to work with the work hood of the present invention, the worker first covers the work hood of the present invention with a hard hat suitable for the worker's head, and then wears the hard hat and work hood and supplies purified air to the inside of the hood. Work with the hose fitted.

The work hood of the present invention is attached to the removable helmet of the helmet is prepared according to the size of the head of the operator to prepare a suitable helmet, and the helmet is used to cover the net mounted on the work hood of the present invention. The net attached to the working hood of the present invention is made of a cloth or a net and preferably made of an elastic body having good elasticity. In addition, the mesh attached to the working hood of the present invention is preferably manufactured to be fixed in a state surrounding the helmet by mounting a rubber band at the bottom. The work hood of the present invention can be removed from the hard hat because it can be removed and washable, and the production itself is convenient. In addition, the working hood of the present invention is fixed to the helmet with a rubber band, so that the hood cover itself does not flow or be pushed out, so that the sight window installed on the hood cover does not flow left / right, up / down, and the sight window is twisted from side to side. As a result, the front view of the worker can be securely secured, and thus the work is easy and has the advantage of being able to respond quickly to an emergency situation.

In addition, since the work hood of the present invention does not use a rivet in the hard hat itself, or a hole for inserting a purified air hose, the hard hat itself has a high impact resistance and may be caused by a strong shock applied to the hard hat when using the hard hat. The risk of a safety accident can be prevented. In addition, the work hood of the present invention is easy to manufacture a work hood because a hole in the hard hat itself or do not use a rivet in a state in which the hard hat and the hood combined.

The work hood of the present invention is attached to the lower end of the inner surface of the hood so as to surround the lower portion of the neck in the state in which the rubber band 42 is mounted to prevent dust and dust from entering during operation.

In addition, the working hood of the present invention is equipped with an air hose that can supply the purified air to the inside of the hood when working with the hood. When the air hose is mounted on the hood of the present invention, the air hose is inserted into the lower part of the hood and the inlet of the hose is mounted to the inside of the hard hat to supply the purified air. And the inlet of the hose is fitted inside the hard hat to supply purified air.

When it is necessary to supply purified air when using the working hood of the present invention, the air hose 50 passes through the inside of the hood so that it can be mounted inside the hard hat. Working hood of the present invention can be equipped with an air hose to distinguish between the need and supply of the purified air is easy to manufacture the work hood and the use of the work hood is convenient.

As described above, the work hood of the present invention can exchange the hard hat according to the size of the worker's hard hat, the removable work hood and the hard hat can be detached and detached, the laundry is easy to wash the work hood with the safety hat separated and the hole in the hard hat. Since no punctures or rivets are used, the helmet itself is strong in impact resistance, has high safety, ensures the widest field of view and prevents the flow of sight glass, and dust, toxic gas particles and other foreign matters are fixed to the hood cover. Preventing symptoms can prevent workers' respiratory diseases. In addition, it is possible to prevent choking and oxygen deficiency during work by keeping the amount of purified air supplied to the worker constant as necessary.
