Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a hand-held manual fire extinguisher that can be carried by hand, and an accumulator fire extinguisher that doubles as an automatic fire extinguisher installed in a place where fire is used, and is obtained with a particularly simple structure.

[0002]

[Prior art]

 Normally, a manual fire extinguisher attaches a valve case with a drug injection port to the base of a pressurized container filled with fire extinguishing agent, and pushes down the hand handle at the upper end of the valve case to release the drug in the pressurized container from the injection port. To do. On the other hand, in an automatic fire extinguisher using such a pressure vessel, the other end of the conduit is provided with a nozzle with a heat sensing plate whose opening is closed by a low melting point metal that melts by fire heat at the other end of the pressure vessel. It is attached to the base, and the nozzle with the heat sensing plate is installed in a place where a fire is likely to occur, and when a fire occurs, the heat sensing plate will automatically drop off and the nozzle will open to release the drug. .

[0003]

[Problems to be solved by the device]

 There are many demands to install both such a manual fire extinguisher and an automatic fire extinguisher, but there was a problem in terms of cost and installation location because the pressurized container and other parts increased accordingly. On the other hand, although there are manufactured fire extinguisher that have both manual and automatic functions in one pressurized container, it is expensive because a special valve case is attached to the base of the pressurized container. And was poor in versatility.

[0004]

[Means for Solving the Problems]

 As a result of various studies in view of this, the present invention has developed a pressure accumulating fire extinguisher capable of easily having both a manual function and an automatic function.

That is, the present invention has a connection opening opened by a manual handle, and a valve case having a medicine injection port provided in an internal passage leading to the connection opening and a mouthpiece of a container for filling a fire extinguishing agent. A joint holder having a through hole that communicates the connecting port and the base, and a branch hole branched from the through hole and having a jetting nozzle with a heat sensing plate is attached.

【Example】

 Next, the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a conventional manual fire extinguisher, in which a manual handle (3) is pushed down onto a mouthpiece (2) of a container (1) filled with a pressurized fire extinguishing agent. A valve case (5) having a structure for discharging the drug in (1) from the injection port (4) is tightly screwed together. In the figure, (6) is a safety stopper for preventing erroneous operation, (7) is a pressure indicator for displaying the pressure in the container (1), and (8) is a siphon tube.

According to the present invention, a joint holder having a nozzle with a heat sensing plate as described below is mounted between the pressure container and the valve case of such a conventional hand-held fire extinguisher. It is characterized by this. That is, the joint holder (15) has a through hole (10) in a vertical direction as shown in FIGS. 2 and 3, and a heat sensing plate is provided at a tip of a branch hole (11) from the through hole (10). This is a structure in which the other end of a conduit (14) provided with an injection nozzle (13) with (12) is attached. The connection opening (16) at the lower end of the valve case (5) with the joint holder (15) is normally closed by a valve stem (17) operated by a manual handle (3). The internal passage (18) of the valve case (5) connected to the connection port (16) continues to the external drug injection port (4) as shown in FIG.

According to such a fire extinguisher of the present invention, the pressurized medicine in the container (1) is normally stored in the through hole (10) of the joint holder (15) and the heat sensing plate (12). The inside of the closed nozzle (13) and the inside of the conduit (14) and the lower surface of the valve stem (17) are filled. Therefore, in order to use this fire extinguisher as a manual fire extinguisher, push down the valve handle (17) by pushing down the manual handle (3) as in the conventional manual fire extinguisher of Fig. 1, and connect the valve case (5). The fire extinguishing agent in the pressurized container (1) is injected from the injection port (4) to extinguish the fire by opening the mouth (16).

On the other hand, when using this fire extinguisher as an automatic fire extinguisher, install the fire extinguisher shown in FIG. 3 on the wall of the kitchen or other places where there is fire, and set the heat sensing plate (12) as the source of fire. Face it. Since the heat sensing plate is used to monitor the fire in this way, when a fire actually occurs, the heat sensing plate will fall off due to the heat and the extinguishing agent will be released from the injection nozzle (13). become.

[0011]

[Effect of device]

 As described above, according to the present invention, a joint holder having the functions of an automatic fire detector and a fire extinguishing agent injection nozzle is simply provided between the valve case and the container mouth of a conventional hand-held manual fire extinguisher. An automatic extinguisher that is both automatic and manual can be obtained with a simple structure. In other words, without replacing the conventional valve case, and without using a dedicated valve case, you can achieve the intended purpose simply by adding the joint holder while keeping the parts of the conventional manual fire extinguisher, and it is inexpensive. Is.
