  Next, an embodiment of the present invention will be described. The simple automatic fire extinguisher shown in the embodiment is composed of a box-type main body 01 having an external appearance, a tip box 02, and a support arm 03 that connects the box-type main body 01 and the tip box 02. The main body 01 is, for example, a size that can be installed in the vicinity of the stove B in the kitchen, and the support arm 03 is formed of a flexible tube or the like having flexibility, and the length of the tip reaches the upper side of the stove B. It has a thickness and strength that can support the tip box 02 at the tip.

In order to demonstrate the fire extinguishing function of the fire extinguisher, the fire extinguishing liquid A is stored and a fire extinguishing system that constitutes a spray flow path, and a drive system that performs a fire extinguishing agent spraying operation in the event of a fire, These are housed in the box-shaped main body 01, the tip box 02, and the support arm 03 described above.
The fire extinguishing system includes a sealed container 1, a discharge tube 2, and a shower port 3. The sealed container 1 has a capacity of, for example, about 500 ml and is filled with an appropriate fire extinguishing liquid (potassium carbonate solution or fluorine-based surfactant liquid for oil fires) A, and a screw-type cap 11 with a discharge tube 2 and a high-pressure gas supply path. A gas supply tube 6 to be described later is hermetically mounted and accommodated in the box-shaped main body 01.

  The discharge tube 2 is an appropriate resin tube and has flexibility, and one end reaches the bottom surface of the sealed container 1, and the discharge tube 2 coming out from the box-shaped main body 01 is stored in the support arm 03 and the other end. Is connected to the shower mouth portion 3.

  The shower mouth portion 3 is provided with a large number of small holes enough to allow the fire extinguishing liquid A to fall on the stove B at an appropriate pressure, and is mounted in the tip box 02 so that the small holes face downward.

  The drive system includes a small gas cylinder 4, an operation mechanism unit 5, a gas supply tube 6, a transmission unit 7 and a sensor unit 8.
