FIRE EXTINGUISHER COMBINED USE AS LAMP}

The present invention relates to a fire extinguisher lamp, and more particularly, it relates to a fire extinguishing apparatus which can detect fire and smoke at the installation position of a lamp when a fire occurs inside a tent or a tent in a camping, mountain climbing, And more particularly, to a fire extinguisher combined with a fire extinguisher.

As the level of living has improved recently and the five-day work week has become common, various leisure activities have been activated to utilize the time remaining for many people. As a result, the number of people enjoying outdoor camping activities, fishing, and mountain climbing is increasing to be.

Also, due to the global recession, more and more people are going to enjoy leisure at affordable prices, and as a result, more and more people are camping in tents that are cheaper and more experienced than pensions or condominiums.

Generally, in order to perform various leisure activities such as fishing and camping in the outdoors, it is necessary to prepare a lot of leisure goods, and among these leisure products, there is an outdoor lantern which is indispensably used at night. The lantern for the outdoor has conventionally been mainly used as a lantern for burning fuel such as gasoline or butane gas. However, since such a conventional combustion type camping lantern requires a pressurizing process to pressurize the fuel cell during the initial operation, It is inconvenient, requires separate fuel and, in some cases, there is a risk of fire.

Accordingly, an electric lantern using a battery has been developed and used to replace such a conventional combustion type lantern. Such an electric lantern generally includes a body in which a battery is housed, a reflector coupled to the front of the body, And a glass and a cap which fix the bulb and the bulb which are installed and are emitted from the battery by electricity and protect the bulb and the reflector.

FIG. 1 is a perspective view of a conventional electric lantern, and FIG. 2 is an exploded perspective view of a conventional electric lantern.

Referring to these drawings, the lantern 100 includes a body 110, a bulb 120, a cover 130, and a power connection line 140. Here, the body 110 includes a body 111, a power and brightness control switch 112, a cover coupling part 114, and a socket 115.

The body 111 is formed in a generally cylindrical shape and has a flat bottom surface so as to be stably placed on the ground. A rechargeable secondary battery is provided inside the body 111, and a power connection line 140 are detachably connected to each other.

The power and brightness control switch 112 is located on the side of the body 111 and the user can control the on / off and brightness of the lantern 100 using the control switch 112. In addition, various circuit configurations are provided inside the body 111 to control the state of the bulb 120 according to the operation of the control switch 112. [

The cover engaging portion 114 is formed in a columnar shape on an upper portion of the body 111. A male screw is formed on the outer circumferential surface of the cover engaging portion 114 and the socket 115 is positioned at the upper end of the cover engaging portion 114 . And the bulb 120 is detachably coupled to the socket 115. In addition, the cover portion 130 is detachably coupled to the body portion 110 to protect the bulb 120. A light transmitting window 131, an engaging part 132 and an upper finishing part 133. The light transmitting window 131 is cylindrical and transmits light from the bulb 120 to the outside.

The coupling portion 132 is fixed to the lower end of the light transmission window 131 and the coupling portion 132 is formed with a female thread to be coupled to the cover coupling portion 114 of the body portion 110, (133) is fixed to the upper end of the light transmission window (131).

On the other hand, when outdoor activities such as mountain climbing and camping are carried out in summer, various insects such as mosquitoes and fleas may be bitten. In order to prevent this, there is a case where the inside of the tent for camping and the surrounding area are separately smoked. However, such a method of eradicating insects by using a mosquito repellent means that it is necessary to pay attention to sleep at the time of sleeping due to a moxibustion which is harmful to the human body, and there is a high risk of fire due to carelessness. In addition, there is a high risk of fire due to the use of a burner for cooking in a tent or a tent or a material of a tent or a tent made of fibers or plastics which is weak against heat and fire even when a fire occurs.

Accordingly, the development of a fire extinguisher lamp that can actively and promptly cope with a fire that may occur in a tent or a tent while outdoor activities such as mountain climbing and camping are maintained while maintaining the merits of the electric lantern described above Is emerging.
