The present invention relates to a fire extinguisher, and more particularly to a fire extinguisher having a transparent window so as to determine the amount of the extinguishing powder stored in the fire extinguisher.

Fire extinguishers include foam fire extinguishers, powder fire extinguishers, halo fire extinguishers, and carbon dioxide fire extinguishers, depending on the drug used and the mechanism thereof. Most small fire extinguishers installed in apartments, schools, factories and large buildings are powder fire extinguishers. Powder fire extinguishers are devices that emit chemicals using non-combustible high-pressure gas such as nitrogen or carbon dioxide by using specially processed sodium hydrogen carbonate powder. .

General powder fire extinguishers are difficult to manage because the amount of fire extinguishing powder stored in the case cannot be observed from the outside. For example, when a powder fire extinguisher is stored for a long time in a humid place or a harsh environment, fine powder fire extinguishing powders are entangled or hardened with each other, in which case the operation of the powder fire extinguisher is poor or impossible. Then, there is a problem that the powder fire extinguisher cannot be used in case of emergency.

In addition, the airtightness of the bonded portion is poor, the problem that the digestive powder leaks through the edge of the transparent window also occurs.

In one embodiment of the present invention, there is provided a fire extinguisher with a case in which extinguishing powder is stored, comprising: an opening formed in the case; A transparent window whose edge is supported on an inner surface of the case and has a central portion penetrating the opening; And it provides a fire extinguisher with a transparent window made of a fixing cap which is screwed to the transparent window fixed to the outside of the case.

In the fire extinguisher equipped with a transparent window according to the present invention, the transparent window, a flange supported on the inner surface of the case; A cylindrical body protruding from the center of the flange and penetrating the opening and having a thread formed on an outer circumferential surface thereof; And it may be made to include a transparent glass for closing the end of the body.

Extinguisher equipped with a transparent window according to the present invention, may further comprise a sealing interposed between the edge of the transparent window and the inner surface of the case.

The fire extinguisher with a transparent window according to the present invention may further include a sealing interposed between the outer surface of the case and the fixing cap.

The transparent window according to the present invention is stably mounted to the case of the fire extinguisher by screwing with a fixing cap disposed on an outer surface of the case after being inserted into an opening formed in the case. Therefore, according to the present invention, the mounting of the transparent window is very easy, there is an effect that the workability is improved.

The transparent window and the fixing cap according to the present invention are screwed to close the opening formed in the case. The sealing is interposed between the transparent window and the case and / or between the fixed cap and the case. Therefore, according to the present invention, there is no fear of poor bonding or the like, and therefore, there is no fear of the extinguishing powder leaking along the edge of the transparent window.
