Description

Fully-burning spray gun head

Technical Field

The utility model belongs to the technical field of the ignition tool, especially, abundant spray gun head burns.

Background

The outdoor cooker generally refers to a burner and fuel (a butane gas tank) which are used for cooking food and boiling water outdoors, and is very convenient to carry. At present, the effect of furnace end has been replaced to the spray gun head, makes flame liberate from fixed position, is convenient for ignite the bonfire, now bakes food. The spray gun head is a new outdoor article, belongs to a field cooker, and is an ignition heating tool derived from the existing butane gas tank.

At present, traditional spray gun head is including the handle that is used for with the gas pitcher joint and the ignition pipe of going out the fire, and the inside jet-propelled chamber that is used for with the gas pitcher intercommunication that is provided with of handle is provided with on the handle and acts on the adjust knob that the jet-propelled chamber is used for adjusting the firepower, is provided with the flame projecting pipe on the ignition pipe. A copper pipe is connected between the jet cavity in the handle and the flame-spraying pipe, so that fuel is conveyed from the jet cavity to the flame-spraying pipe. Because the gas in the gas tank is liquefied through high pressure and then stored in the gas tank, when the pressure is released, the fuel liquid in the gas tank is partially vaporized and enters the gas injection cavity, and then enters the flame injection pipe through the copper pipe. Because the spray gun head needs to be adjusted the flame angle in the use, but the gas pitcher also can follow the production and excessively incline or directly be the inversion state in angle regulation for the liquid stream that fires of gas pitcher flows to the jet-propelled intracavity, thereby leads to the flame of burning to be the naked light state, can't be used for the welding to use. In addition, because the vaporization of the fuel liquid is not very sufficient, the pipe diameter of the copper pipe is relatively thick due to the fact that the existing copper pipe is matched with the pagoda joint, the pipe body is short, and the fuel cannot have sufficient vaporization time, so that the flame generated just after ignition can be preheated in an open flame state (the duration is long), the flame cannot be used for jet combustion, the jet flame can be formed in a long time, and the fuel liquid cannot be fully vaporized all the time during the jet combustion, so that the utilization rate of the fuel combustion is reduced. In the prior art, a handle of the spray gun head is fixedly connected with an ignition tube (connected by a copper tube), the spray gun head cannot be subjected to angle adjustment, the wrist posture is adjusted for a long time in the using process, people are easy to feel fatigue, and the body part is inconvenient to move under some special environments, so that the problem of inconvenience in use to a certain extent exists no matter the wrist posture direction is adjusted or the body part is moved, and the spray gun head cannot be well ignited.
