Description

Butane gas burner

The present invention relates to a burner for butane gas, and more specifically, the ignition switch is placed inside the burner body so that the ignition switch or lever cannot be inadvertently operated by the user's carelessness so that the lid is opened and operated only when necessary, and the butane gas cylinder is By mounting the lever on one side of the enclosure, it is possible to control the butane gas cylinder even in a narrow structure where the lever for protruding the butane gas cylinder can not be protruded to the outside. The present invention relates to a butane gas burner that can fundamentally prevent the release of butane gas and thus prevent fire or safety accidents caused by gas explosions.

In general, butane of butane gas, which is one of many gases used in homes and businesses, is one of chain hydrocarbons, has a chemical formula of C4H10 and a molecular weight of 58.1. There are two isomers, n-butane, in which four carbon atoms are continuously bonded in a chain, and isobutane, in which three carbon atoms are bonded to one carbon atom.

n-butane is also called normal butane, and often referred to as butane. It is contained in natural gas or petroleum cracking gas. Under normal temperature and pressure, it is a colorless gas, which burns well if air or oxygen is present, and the calorific value is 27,600 kcal / m3.

It is used as fuel for liquefied petroleum gas, and is also used for the production of butene and butadiene as petrochemical raw materials. It has a good liquefaction and is used as a main component of gas lighter fuel.

Isobutane is contained in natural gas or petroleum cracking gas like n-butane. Colorless gas, highly flammable and easily liquefied. Combination with propylene yields high octane gasoline. It is also used as a raw material for synthesizing isobutylene.

Butane gas with this characteristic is filled in a small sized aluminum container at a proper pressure and is sold at a supermarket or convenience store.The user purchases a butane gas container on a commercially-available small home burner, which is easy to move around. It is used when cooking food or baking meat when camping.

Such a burner is a name for a device that burns gas to obtain a high temperature, and has been the basis of various burners since the invention of R. W. Bunsen in Germany in 1855, and is also referred to as Bunsen or simply burner (or bunsen burner).

Such a burner ejects the gas introduced into a rubber tube into a small hole of a metal cylinder of 10 cm in height and sucks air from the air hole to mix the gas by using a pressure drop in the vicinity thereof. When ignited at the top, the gas continues to ride, and the flame can be controlled by varying the amount of gas and the size of the air holes.

The inside of the flame is a mixture of carbon monoxide, hydrogen, carbon dioxide, water vapor, etc. by the combustion of gas mixed with air, and because it is reducing, it is called reducing flame or flame. The temperature of the reducing flame is 300 ℃ at the bottom and 1,500 ℃ at the front end.

The outer part of the flame is called an oxidative flame or a top flame because hydrogen or carbon monoxide reacts with the surrounding air and burns to produce carbon dioxide and water vapor. To this.

Gas burners that boast such thermal power are commonly used city gas burners, propane gas burners, butane gas burners, but the butane gas burners that use butane, which is usually small and easy to move, are the most widely used.

This butane gas burner places a butane gas cylinder in a commercially available butane gas cylinder inside a housing located on the right side of the combustion unit, with the discharge port at the tip of the butane gas cylinder being directed toward a coupling hole of the housing in which the burner pipe is coupled. Position the fixing bar of the enclosure on the recess of the tip.

When the user lowers the lever mounted on the outside of the burner to the lower side, the butane gas cylinder inside the enclosure is advanced toward the coupling hole of the enclosure to be in close contact with the discharge port, and the butane gas inside the butane gas cylinder is discharged to the outside through the discharge port at a suitable pressure and then recombined. The sphere is then ready for supply to the burner via the burner tube.

At this time, when the user operates the ignition switch, the flame is splashed on one side of the burner nozzle and the butane gas discharged to the burner nozzle is caught with fire, and the burner is burned.

However, such a butane gas burner protrudes the lever and the ignition switch on one side of the burner, and when the ignition switch is rotated a little while the lever is inadvertently released, all butane gas in the butane gas cylinder is discharged to the outside through the nozzle of the combustion unit. In narrow spaces, there was a safety problem that could be a choking hazard.

In addition, when the butane gas is inadvertently discharged to some extent, if the cigarette light is attached, there is a problem that explosion and fire occur along with the explosion, causing a great loss of lives or property damage.

The present invention is to solve the above problems, the ignition switch is placed inside the burner body so that the ignition switch or lever can not be inadvertently operated by the user to open and operate the lid only when necessary, but the butane gas cylinder is seated By installing a lever on one side of the enclosure, it is possible to control the butane gas cylinder even in a narrow structure that cannot protrude the lever for the operation of the butane gas cylinder.Butane gas is caused by the user's carelessness because the lever does not protrude outside. The purpose of the present invention is to provide a butane gas burner that can prevent the emission of gas and prevent fire or safety accidents caused by gas explosion.

In order to achieve the above object, the present invention has a coupling hole on one side and a coupling hole coupled to a fixed bar at the top is installed in the nozzle and the butane gas of the butane gas cylinder mounted on the operating body and pipe connected to the burner tube from the nozzle A butane gas burner having an ignition switch to ignite;
