The present invention relates to a fire extinguisher, and more particularly, to make it easy to refill, to improve the efficiency of fire fighting education and to use the fire extinguisher as a toy.

In general, a fire extinguisher is a filling container filled with a fire extinguishing powder, a discharge handle for controlling the discharge of the extinguishing powder filled in the filling container, and an injection to inject the extinguishing powder discharged through the discharge handle into a flame. It is composed of a hose, the extinguishing powder filled in the filling container is mainly used a first ammonium phosphate, the compressor body is used nitrogen or carbon dioxide.

On the other hand, the powder extinguisher as described above is classified into a compression type and a pressurized type according to the filling method of the compressor body, the accumulator is a powder gas and the compressor body is stored together, the pressurized type is a compressor body is stored in a separate gas cylinder, Inexpensive pressure storage is mainly used in terms of price.

However, the powder fire extinguisher configured as described above cannot be reused once it is used. During fire fighting education, the fire extinguisher is not used in a fire fighting training course. Familiarity with usage is falling.

In addition, as described above, the fire extinguisher does not fully know how to use a fire extinguisher, and does not effectively extinguish a fire in extinguishing a fire using a fire extinguisher without having experienced an actual fire suppression with a fire extinguisher. This failing case is frequently occurring.

In order to solve this problem, Korean Utility Model Registration No. 258493 has provided a fire extinguisher and a filling device, and the fire extinguisher for fire fighting education which can be used without additional charge during fire fighting education by directly filling a fire extinguishing liquid. However, since the fire extinguisher takes a large amount of a digestive fluid to be used for firefighting education for a large number of trainees, there is a problem that it is not preferable in terms of cost burden.

In order to solve this problem, a practice simple fire extinguisher having the same operation and structure as a real fire extinguisher has been proposed, but the actual spraying liquid is not sprayed, thus reducing the visual education effect and causing no interest of the trainee. there was.

In addition, the conventional fire extinguisher was not only contaminated the wall or floor around the educational center by the extinguishing liquid sprayed in the training course, there was a risk that the digestive fluid can be sprayed on another person by mistake. In order to solve this problem, an air jet fire extinguisher (Korean Utility Model Application No. 1997-3257) and the like have been proposed, but there is a problem that no visual effect can be obtained at all except an auditory effect as air is injected.

The present invention has been made to solve such a problem, and the first object of the present invention is to provide a fire extinguisher capable of easily refilling pressure without using a compressor or the like.

Another object of the present invention is to provide a fire extinguisher that can be filled with water so that it can be practiced by using toys, education, and the like and can also be used in actual fire sites.

Still another object of the present invention is to provide a control mechanism that can simply control the injection and closing of water.

The present invention for achieving this object

In the fire extinguisher body having a fire extinguisher main body, a head mounted on the top of the fire extinguisher body, the head including the operation lever and the injection port for spraying the injection liquid supplied from the fire extinguisher body by the operation lever operation,

At the bottom of the fire extinguisher body, an air injection unit for filling air pressure into the fire extinguisher body is formed.

The side of the fire extinguisher body is equipped with a connection valve for injecting water,

The siphon tube of rubber material located inside the fire extinguisher main body and connected to the injection port to extract water by internal pressure is in close contact or opening by the operation of the operation lever.

In addition, the air injection portion of the fire extinguisher is characterized in that it further comprises a connector that can be connected to the compressor.

The air injection unit is composed of an air inlet handle which is moved up and down for air injection, and an air injection pump configured to fill air into the inside by the vertical movement of the handle.

In addition, the fire extinguisher may further be configured with a pressure gauge for displaying the internal pressure and a safety valve for securing the stability of the fire extinguisher body by ejecting the contents of the interior when the internal pressure rises above a predetermined level.

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

1 is a view showing the inside of a fire extinguisher according to an embodiment of the present invention, the water inlet 11 and the air injection pump 13 and the air injection pump in which water is injected below the fire extinguisher main body 1. An air inlet handle 14 is formed to fill the pressure into the fire extinguisher by moving up and down, and checks the pressure inside the safety valve to discharge the filling to the outside until the pressure falls below a predetermined pressure. ) Is installed.

In addition, the upper part of the fire extinguisher, the contents of the inside, that is, the injection port 21 is discharged and the hose 22 connected to the injection port, the upper handle 23 and the lower handle 24 for opening and closing the injection port And, and the handle is fixed arbitrarily moving so as not to spray the contents is fixed to the handle pin 25 is formed, a pressure gauge 26 to indicate the pressure inside the fire extinguisher is formed.

Inside the fire extinguisher is a siphon tube of rubber material, the opening and closing of the siphon tube is connected as shown in Figure 2, when the upper and lower handle is in the OFF state, the upper and lower close contact to prevent the injection of water, When it is turned ON, water is discharged by the internal pressure by restoring the original part.

Therefore, the user first connects the hose extending from the water pump or the faucet to the water inlet 11 to fill the water by a predetermined level therein, and then repeatedly moves the air inlet handle up and down, thereby While the air injection pump 13 moves up and down, the pressure inside the fire extinguisher becomes stronger while pushing the outside air into the fire extinguisher.

In this case, the user can fill the air only up to a predetermined pressure while watching the pressure gauge 26, and the safety valve 12 when the pressure exceeds the predetermined pressure in preparation for the possibility that the fire extinguisher body may be damaged by the internal pressure. Discharges the internal fillings to the outside.

Meanwhile, the air injection pump may separately configure an external air injection connector for connecting an external device such as a compressor, and as shown in FIG. 4, a water fire extinguisher connected to a water tank and forcibly supplying water forcibly. It may further include a valve 17.

Figure 3 shows a fire extinguisher according to another embodiment of the present invention, the water inlet 11 is not separately located on the lower side of the fire extinguisher, it is configured to be able to inject water into the lever operating portion, the upper handle (23) and the lower handle (24), the pressure gauge (26), the handle fixing pin (25), the cyphon tube (15) and the stopper portion (16) rotatably coupled with the thread (16) formed on the upper part of the fire extinguisher body (1) 27) is formed.

According to the present invention, even after opening the water inlet of the lower extinguisher and not injecting water, after filling the lever operating part 2 by rotating and injecting water into the air and pumping the air injection pump up and down, Fire extinguisher training will be available.

According to the present invention can be easily filled and digested using the surrounding tools at the learning site or education site, so it is possible to maximize the educational effect as well as the environment without a compressor without using a separate filling solution. There is also an advantage that can be repeatedly performed education.

In addition, since it can be used as a substitute for water guns in summer water play, there is an advantage that there are various applications.
