The present invention relates to a fire extinguishing device, and more particularly, to an automatic fire extinguishing device that can be applied to a vehicle such as a vehicle by increasing the extinguishing capacity to be applicable to a large space.

Generally, a sprinkler is installed indoors to extinguish a fire. The sprinkler is designed to sense the room temperature and sprinkle water when the room temperature exceeds a preset temperature. Here, the sprinkler receives water through the pipe, but when the valve of the pipe is closed, water cannot be sprayed. That is, even if the room temperature is higher than a preset temperature, if the valve of the pipe is closed, it cannot function as a sprinkler.

In addition, when the weather is cold, such as winter, there is a risk that the piping freezes, and even in this case, it is impossible to properly function as a sprinkler. In addition, sprinklers can extinguish a fire only within an angle where water is injected, and there is a problem that it is not possible to extinguish a fire outside the angle where water is injected.

In addition, in the case of an electric fire that occupies a significant portion of the cause of the fire, most of the fire extinguishing facilities are installed on the ceiling and are located far away from the ignition point, resulting in a large fire due to early detection and initial suppression in the event of a fire. Will be a lot.

Hereinafter, a fire extinguishing device and a system according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art to which the present invention pertains can easily carry out. The present invention is not limited to the embodiments described herein, and may be implemented in various different forms. In order to clearly describe the present invention, parts irrelevant to the description are omitted, and the same reference numerals are assigned to the same or similar elements throughout the specification.

First, the agent and the extinguishing agent used throughout the specification of the present invention are the most important components of the fire extinguishing device according to the present invention and are liquid substances that directly extinguish the fire. Therefore, even if it is used as an agonist and an agonist, its meaning does not change, and even when used as an extinguishing agent or an extinguishing agent, it can be interpreted in the same way. In addition, the agent and the extinguishing agent may be used separately or according to their role and function, and in some cases, the same agent may be used.

1 and 2, an automatic fire extinguishing device 1 by an applicant of the present invention has been disclosed. According to this, it is characterized in that it is automatically opened as a fire extinguishing device for obtaining an expansion spray effect according to the gasification of the extinguishing agent and the melting temperature conditions of the nozzle. However, the automatic fire extinguishing device disclosed in accordance with the structural characteristics and the operation of the extinguishing agent must be utilized in a small amount, and the usability and applicability are narrow.
