Description

Educational Fire Extinguishers {FIRE EXTINGUISHER FOR TRAIN}

The present invention relates to the structure of an educational spray fire extinguisher that can be used continuously and repeatedly. It is proposed to have the same operating principle and spraying effect as an actual fire extinguisher, especially when learning the proper use of a fire extinguisher and teaching a fire extinguisher to cope with an emergency. It is a fire extinguisher, and relates to an educational spray fire extinguisher that guarantees a long continuous use by maintaining a continuous charging action and excellent durability of the fuel.

In general, in order to protect valuable lives and property from the risk of fire, various buildings are required to comply with various fire protection regulations (e.g. evacuation routes, life-saving equipment, the provision of non-combustible and extinguishing facilities, and the entry of fire trucks). The mobile fire extinguisher, which is an example of a double fire extinguishing facility, is easy and effective in responding to a fire in an emergency situation, and it is required even in a general home. It is the fact that beach to is essential.

The reason why the portable fire extinguisher is in the spotlight is that it is much easier to use than the buried fire hydrant which enables the high pressure water spray by releasing the coiled pipe which is installed in the hydrant case of the building and minimizes the economic burden of the installation. It can be used and can be used while moving from time to time regardless of location and location.

Therefore, such a mobile spray fire extinguisher has a certain number in a building equipped with a separate fire hydrant, but it plays an important role and knows the proper use of a fire extinguisher in comparison with many possessions. In rare cases, people often come across with fire extinguishers, who are not working properly in the event of a fire, or who are embarrassed and are suffering from irreparable damage.

Therefore, the necessity of education on the proper use of a fire extinguisher is very urgent and it is becoming a major curriculum in adult education such as reserve military and civil defense as well as schools at various levels.

However, in the conventional education, the use of expensive fire extinguishers to enable trainees to operate or demonstrate them individually involves a large economic burden, and in the case of fire extinguishers that cannot be reused due to difficulty in refilling digestive fluids, they are expensive. Is used for educational purposes only and is not economically desirable, and moreover, the spray extinguisher is repeatedly sprayed with the contents (digested liquid) once sprayed around, which causes very dirty contamination of the floor. In practice, the education has to be resumed after the contaminants are removed or cleaned from time to time, so that both the educators and the trainees are very troublesome.

Therefore, a practice simple fire extinguisher was also proposed for training, which has the same operation structure as the actual fire extinguisher, which is suitable for learning the opening and closing operation of the valve. And because of the low educational level, the educational effect was low, especially when education was given to younger students, including the dismissal of causing no interest.

Therefore, the air injection type fire extinguishers and the like have been proposed to solve this problem, but other than the auditory effect, no visual effect can be obtained, which is not suitable for education.

Therefore, an educational fire extinguisher having the same operating principle and spraying function as an actual fire extinguisher is urgently needed, and such a fire extinguisher should be capable of being repeatedly reused and should not affect the surrounding environment by spraying.

Therefore, an object of the present invention is to provide an educational fire extinguisher having the same appearance and operation structure as the actual spray fire extinguisher, while the actual liquid sublimated through the heater heated to a predetermined temperature by the external power supply is sublimed into gas It can be injected through the nozzle with the same effect as the spray fire extinguisher of the same, which can increase the educational effect according to the realism and at the same time, it is possible to repeatedly recharge the fuel, which enables continuous and repeated use, and is harmless to the human body. Spraying vanishing smoke ensures a clean educational environment without contaminating the surroundings, even with continued use.
