Description

An education fire-extinguisher device

More particularly, the present invention relates to an educational fire extinguisher, and more particularly, to an educational fire extinguisher, which is provided with a smoke bomb and a battery inside the fire extinguisher body and an ignition rod for igniting the electric power of the battery by the on- The smoke can be operated by using the smoke of the smoke bomb, which is ignited by the electric power source of the battery, and the smoke bomb generates smoke of various colors to maximize the effect of the appearance of the fire extinguisher The present invention relates to an educational fire extinguisher system.

Generally, fire extinguisher is a kind of fire extinguisher which can be cooled quickly by simple operation or air can be evacuated by fire extinguisher. Fire extinguisher is fire extinguisher, powder fire extinguisher, carbon monoxide fire extinguisher and Halon fire extinguisher.

Since a fire extinguisher of this kind can not be used continuously or repeatedly, there is a problem that it is not easy to show a demonstration of how to use the fire extinguisher, or to directly hold the fire extinguisher.

In order to solve such a problem, the inventor of the fire extinguishing device of the present invention has been invented as disclosed in Japanese Patent No. 1591756.

4, the conventional educational fire extinguishing system includes a handle 210 having a switch 211 and a discharge hose 201 for discharging the fire extinguishing liquid to the outside according to the operation of the handle 210, As shown in FIG.

A fire extinguishing solution tank 220 in which fire extinguishing mist liquid in which fume material is melted is installed in the fire extinguisher main body 200 and a heating tank 230 connected to the fire extinguishing solution tank 220 and the flow pipe 221, And is installed inside the extinguisher main body 200.

A heater 231 connected to a power supply line 240 supplying power from the outside is screwed into the outer circumferential surface of a flow pipe 221 passing through the heating tank 230, And a motor 241 capable of supplying fire extinguishing liquid to the inside of the heating tank 230 is installed inside the fire extinguisher main body 200 so as to be connected to the power line 240.

Therefore, when a force is applied to the hand holding the handle 210 in a state where the safety pin 212 coupled to the handle 210 is pulled out, the switch 211 provided on the handle 210 is turned on and the heater 231 Is supplied with power from the power line 240 and generates a high temperature.

When a high temperature is generated in the heater 231, the motor 241 installed in the fire extinguisher main body 200 is operated to supply the fire extinguishing liquid stored in the fire extinguishing solution tank 220 to the heating tank 230, The fire extinguishing liquid supplied to the heating tank 230 is vaporized in the heater 231 generating high heat and the vaporized fire extinguishing liquid is discharged to the outside through the discharge hose 201 to manifest the actual use of the fire extinguisher You can.

However, a problem with the conventional fire extinguishing apparatus is that a high-temperature heat can be generated in the heater 231 provided inside the heating tank 230 by using the power line 241 connected to an external power source, It is not easy to move and the educational fire extinguishing device can not be displayed in a place where the power line 241 is not connected to the power source.

Since the heater 231 generates fumes by supplying and vaporizing the extinguishing mist liquid that has flowed into the heating tank 230 in the state of generating heat of 300 ° C or more, the power consumption is intensive and the heat generated by the high temperature Which causes a problem that the person who displays the digestive system frequently gets burned.

Then, the fire extinguishing liquid vaporized through the heater 231 is diverted to the outside through the discharge hose 201. At this time, since the fogging material made of oil is melted in the fire extinguishing liquid, A problem has arisen that it has to be cleaned.

The heat of the heater 231 causes various components of the rubber material installed in the fire extinguisher main body 200 to melt.

Particularly, since the conventional fire extinguisher body 200 is provided with the fire extinguishing solution tank 220 containing the fire extinguishing liquid and the heating tank 230 for heating the fire extinguishing liquid supplied from the fire extinguishing solution tank 220, Since the load of the apparatus is increased, children with weak strength directly carry the fire extinguisher main body 200 directly to the place where the fire is generated, which makes it difficult to carry out early education in which the fire is burned.

On the other hand, like the utility model No. 475272 registered in advance, the educational fire extinguisher apparatus was invented.

In the conventional fire extinguisher system, at least one fire extinguisher is installed on the upper surface of the body formed in a hexahedron, and an extinguishing device for supplying the fire extinguishing liquid to the fire extinguisher is separately provided from the body.

In this case, the fire extinguishing liquid supplied to the extinguisher is supplied as high heat. When the pressure is applied by holding the handle of the extinguisher by hand, the extinguishing mist liquid supplied to the extinguisher through the body is discharged to the outside It is divergent.

However, since the connection pipe connecting the conventional fire extinguisher and the fire extinguishing liquid is supplied with the fire extinguishing liquid at a high temperature, dew is generated around the connection pipe in the cold winter season. At this time, There is a problem that a large amount of water is generated due to the dew and water droplets in the aerosol state due to the temperature difference around the discharge hose 201.

In order to solve the above problems, according to the present invention, there is provided a fire extinguisher which includes a fire extinguisher main body and a battery, and a controller for supplying the battery power to the smoke fuels by the On signal of the operation switch, It is possible to reduce the manufacturing cost of the educational fire extinguishing system and to install the solenoid valve inside the fire extinguisher body so as to be connected to the control unit, When the solenoid valve opens the communication hole by the control signal of the control unit, a large amount of mist is diverted to the outside through the discharge hose. At this time, A fan is installed on the upper surface of the fan, Since the smoke of the bullet is strongly emitted to the outside through the discharge hose, it is possible to maximize the visual effect, and fumes are generated in colors such as white, red, yellow, and black depending on the color type of the smoke bomb attached to the main body of the fire extinguisher And it is an object of the present invention to provide an educational fire extinguisher apparatus which can maximize the effect of fire extinguisher appearance.
