Hotels, inns, etc. are legally required to install automatic fire extinguishing devices such as sprinklers in the guest rooms, but hotels and inns without such equipment are forced to install fire extinguishing devices as soon as possible. Recently, some businesses have been forced to close down due to the enormous costs involved in renovating the building and installing the fire extinguishing equipment themselves.

These problems include the high cost of new fire extinguishing equipment, such as sprinklers, which are required to be installed in conventional hotels and inns, or the fact that new fire extinguishing equipment, like conventional fire extinguishers, must be operated by a person. If automatic fire extinguishing equipment could be provided that could solve the problem of not being able to function properly, that could be installed at an extremely low cost, and that could automatically perform the extinguishing function in the event of a fire even when unattended. This is extremely beneficial in terms of eliminating the loss of human life.

The automatic fire extinguishing equipment according to the present invention was conceived based on the above-mentioned demands, and uses a heat-sensitive variable element to keep the valve opening/closing mechanism of the injection nozzle in a general fire extinguisher in a closed state, thereby preventing the occurrence of a fire. The valve opening/closing mechanism is operated to open the valve by deforming or breaking the thermosensitive change element due to an abnormally high temperature during the operation.

Next, the automatic fire extinguishing equipment according to the present invention will be described in detail with reference to an illustrated embodiment. FIG. 1 is a sectional view showing the structure of one embodiment, in which 1 is a fire extinguisher container, 2 is an injection nozzle, and The fire extinguishing agent 3 in the fire extinguisher 1 can be sprayed in a mist form at a wide range of spray angles. Nozzle 2
A cylindrical cap 4 at the top of the container 1 in which the
A cylindrical valve 6 with a through hole 5 formed in a part of the side surface of the upper end is slidably installed inside the valve. In this valve 6, an upper end 7 of the through hole 5 is closed, and an operating rod 8 extends above the closed upper end 7. It is continuously attached to a part of the lever 9. The lever 9 is rotatably attached to a bearing 11 protruding from a pedestal 10.
The tip 9a on the side of the nozzle 2 and the tip 10a of the pedestal 10 are connected via a fuse-shaped thermosensitive element 12 which does not break at room temperature but breaks at high temperature. The height of the thermosensitive variable element 12 is shorter than the height of the bearing 11, and therefore the lever 9 is inclined with respect to the bearing 11 such that the front end 9a side is lower and the rear end 9b side is higher.

The thermosensitive change element 12 is melted at a temperature of about 65° C., which is filled between a plate 14 having a hook portion 15 at one end thereof and the opposite hook portions 15 on this plate, as shown in FIG. 2, for example. The plates 14 are made of a special connecting metal 16, and when the connecting metal 16 is melted by high heat, both plates 14 are separated from each other.

The automatic fire extinguishing equipment according to the present invention has the above-mentioned structure, and if a plurality of them are installed, for example, with the container 1 placed in a corner of the room and the nozzle 2 directed toward the center of the room, it can be used in the middle of the night or when you are away. If a fire breaks out without anyone noticing and the temperature inside the room rises abnormally, extinguishing agent will be automatically sprayed into the room. That is, when the indoor temperature rises due to a fire outbreak, the heat-sensitive element 12 connecting the tip of the lever 9 to the pedestal 10 breaks or deforms, and the rear end 9b of the lever 9 is pulled by the tension spring 13, causing the lever to operate. When the rod 8 is pushed down by the lever 9 to communicate the through hole 5 of the valve 6 with the nozzle channel 2a, the fire extinguishing agent 3 in the container 1 is sprayed from the nozzle 2 over a wide area in the room in the form of mist. For example, if this fire extinguishing equipment is in a hotel room, two
If each fire extinguisher is placed in the corner of a room, the extinguishing agent sprayed from each fire extinguisher will fill the room in about 20 seconds, making it possible to adequately extinguish a fire immediately after it occurs. For household use, it can be placed not only in the living room and bedroom, but also in the kitchen, for example, by placing it near the gas range with the nozzle 2 pointing in the direction of the range, so that the oil pot will not catch fire. In the event of a fire, extinguishing agent is automatically sprayed in that direction, and the extinguishing function can be activated instantly.

As described above, in the fire extinguishing equipment according to the present invention, the valve is opened when the heat-sensitive variable element is changed by the heat generated when a fire occurs, so that fires that occur without people noticing can be prevented at an early stage. Since the fire can be extinguished automatically, it can greatly contribute to eliminating the loss of precious human life due to fire. In addition, since the cost of equipment is as low as upgrading a conventional fire extinguisher, installation of fire extinguishing equipment, which is required in hotels, inns, and other places where large numbers of people gather, is significantly cheaper than conventional sprinkler equipment. It has extremely beneficial effects in that it can be easily and quickly installed and repaired.
