Description

Head assembly of portable gas burner

The present invention relates to a head assembly of a portable gas burner, and more particularly, to a head assembly of a portable gas burner connected to a venturi tube and having a flame formed therein.

In general, portable gas burners are easy to carry and can be conveniently used outdoors or indoors by selectively combining can-type gas containers, and thus are widely used in going out or restaurants.

1 is a perspective view of a head assembly of a conventional portable gas burner, and FIG. 2 is a longitudinal sectional view of FIG. 1.

1 and 2, the head assembly 10 of the conventional portable gas burner is coupled to the cylindrical head main body 4 connected to the venturi tube 2, the upper end of the head main body (4) It is provided with a cover 6. The head body 4 is formed with an air hole 8 penetrated at the center thereof, and an ignition device 1 is installed at the outer surface. A plurality of gas discharge grooves 3 are formed at the lower edge of the cover 6. The gas discharge groove 3 is a portion which forms the main flame of the gas burner (not shown) by coupling with the head body 4. On the upper side of the cover 6, four pairs of auxiliary discharge holes 5 are arranged at an angle of 90 degrees, and the auxiliary discharge holes 5 are for forming an auxiliary flame inside the main flame. The cover 6 is fastened to the head body 4 by bolts 7.

However, in the head assembly 10 of the conventional gas burner, since the auxiliary discharge holes 5 of the cover 6 fastened to the head body 4 are arranged at an angle of 90 degrees, the gas for forming the auxiliary flame is evenly distributed. Since it is not distributed and is concentrated only at one point, the amount of gas to oxygen is relatively increased. Therefore, as shown in FIG. 3, there is a problem in that a so-called lifting phenomenon occurs in which the auxiliary flames do not adhere to the surface of the auxiliary discharge hole 5 and rise. In addition, since the auxiliary flame is biased, it cannot be evenly spread, and thus there is a problem that the thermal efficiency is lowered. On the other hand, the head assembly 10 of the conventional gas burner has a problem that the flame is changed from blue to red, so-called sulfur salt phenomenon occurs because the gas is biased when using the gas burner for a long time.

The present invention was conceived in view of the above problems, and the thermal efficiency is increased by installing a ignition member made of brass formed with a dual gas discharge hole that is radially disposed on the structure of a conventional head body. It is, of course, an object of the present invention to provide a head assembly of a portable gas burner whose structure is improved to prevent lifting and sulfur salts.
