Claim 8:
9. An automatic self-extinguishing fire device to protect an object, the device consisting of:
a colored fire-extinguishing substance;
a hose having a straight tubular body having an entire length that is linear from a first end of the hose to a second end of the hose;
a first pressing ending connected to the first end of the hose and a second pressing ending connected to the second end of the hose, wherein the colored fire-extinguishing substance is inside the hose, wherein the first pressing ending and the second pressing ending are made of a metallic material;
a first closing screw connected to the first pressing ending at a first connection and a second closing screw connected to the second pressing ending at a second connection;
a first protector made of a heat shrinkable material covering the first connection and a second protector made of heat shrinkable material covering the second connection, wherein the hose does not touch the first protector or the second protector;
a pressure valve for filling by the colored fire-extinguishing substance that is located by one of the pressing endings;
a spherically shaped floating body located inside the hose, the spherically shaped floating body having a reflexive color, wherein the spherically shaped floating body descends in the hose;
a plurality of flexible stretching straps attached to the hose, the flexible straps are adapted to be wrapped around the object to be protected;
an outlet valve connected to the hose, the outlet valve including a bimetal or memory metal that at a set temperature opens the outlet valve and the colored fire-extinguishing substance is released outside the hose;
wherein the automatic self-extinguishing fire device is free of electric or electronic components;
wherein a sealing or integrity of the hose is disrupted under effects of a fire;
wherein the hose is at least partially flexible and the colored fire-extinguishing substance in the hose is under pressure;
wherein the hose is transparent in order to observe an inner content of the hose;
wherein the hose includes a pyrotechnical substance configured to cause an increase in pressure inside the hose to manually activate the colored fire-extinguishing substance;
the hose has at least one place with a weakened cross-section configured to allow an outflow of the colored fire-extinguishing substance during the increase in pressure inside the hose caused by the pyrotechnical substance;
wherein after manually activating the pyrotechnical substance, the hose is torn at the weakened cross-section and the colored fire-extinguishing substance leaks into an environment; and
wherein the hose has a control surface with a color corresponding to a color of the colored fire-extinguishing substance, as perceived from an outside, on an outer surface of the hose.
