Abstract

The utility model relates to a combustor for gas-fired utensils, comprising a combustor head (4), a plurality of head firing holes (5), secondary air tube (6) and other members. The utility model is characterized in that the secondary air tube (6) is a hollow and tubular spool with two end openings, which upper end is arranged in the center of the head firing holes (5) and the lower end passes through the housing of the combustor head (4), thus forming a path for secondary air. When in use, the gas mixture in combustor head firing holes (5) combusts to generate a negative pressure over the secondary air tube (6), so the secondary air is drawn into flame core via the secondary air tube (6) for fully combustion. Solving technical problems of incomplete combustion due to oxygen shortage or late supply inside the flame, the utility model has the advantages of ideal combustion status, improved heating efficiency, energy saving and reduced CO emission.

Description

A kind of combustion gas tool burner

[technical field] the utility model belongs to combustion gas tool field, particularly a kind of combustion gas tool burner.

The combustion system of [background technology] existing combustion gas tool generally all is an atmospheric burning type, combustion gas sprays at a high speed from nozzle, still air (primary air) enters injector together around the injection, form combustion mixture and enter burner head after slow down, combustion mixture fire hole from the head flows out, lighted the cost flame of lighting a fire, flame (flame envelope) auxiliary air all around helps burning, but flame inside (internal flame) oxygen supply is untimely insufficient, the higher hydrocabon anoxic is heated, decomposite carbon black, the situation of yellow flame and over-emitting black exhaust appears in (diameter less than 1 micron particle), influences combustion efficiency.

[summary of the invention] the utility model provides to make auxiliary air enter internal flame for overcoming the deficiencies in the prior art, a kind of combustion gas tool burner of overheavy firing effect.

The utility model comprises burner head 4, head fire hole 5, auxiliary air pipe 6 etc., it is characterized in that auxiliary air pipe 6 is tubes of hollow and both ends open, its upper end places head fire hole 5 central authorities, leaves enough slits around the tube wall, is convenient to combustion mixture and flows out, port protrudes on the head fire hole 5, burner head 4 drain pans are passed in the lower end, tube wall and drain pan sealing, and port protrudes in outside the drain pan, the ledge caliber is expanded as bell mouth shape gradually, forms the pipeline that auxiliary air passes through.

After using the utility model, combustion mixture in the head fire hole 5 forms negative pressure when burning above auxiliary air pipe 6, auxiliary air through 6 suction of auxiliary air pipe to internal flame, increase because of the horn mouth effect makes air mass flow, flow velocity is accelerated, and the oxygen supply in the internal flame is in time abundant, burning reaches perfect condition, improve the thermal efficiency, energy savings reduces carbon monoxide emission.

Auxiliary air pipe 6 can be out of shape for adapting to different combustion gas tool needs, and principle is constant, and effect is identical.Coupling head fire hole 5, one holes, auxiliary air pipe 6 upper ends one pipe, lower end can be kept to a pipe or more than the pipe, the middle air distribution 7 that places in the burner head 4 of using connects.

[description of drawings] Fig. 1 is that the utility model is used schematic diagram on gas-cooker, and Fig. 2 is that the utility model is used schematic diagram on gas heater.

[specific embodiment] is from the concrete enforcement of the visible the utility model of Fig. 1 on gas-cooker: combustion gas is from gas nozzle 1 ejection, still air enters injector 3 from primary air hole 2 around the injection, enter burner head 4 after forming combustion mixture, fire hole 5 flows out from the head again, is lighted the generation flame of originally lighting a fire.This flame forms negative pressure above auxiliary air pipe 6, extract auxiliary airs through auxiliary air pipe 6 enters internal flame, helps it fully to burn, and combines with auxiliary air all around together with flame envelope, makes firepower more fierce, and it is more stable to burn.From the concrete enforcement of the visible the utility model of Fig. 2 on gas heater: auxiliary air pipe 6 is out of shape at this, and its upper end distributes according to head fire hole 5, a hole one pipe, and the lower end is kept to two pipes, and is middle with placing the air distributions 7 in the burner head 4 to connect.

Claims

1, a kind of combustion gas tool burner, comprise burner head (4), head fire hole (5), auxiliary air pipe (6) etc., it is characterized in that auxiliary air pipe (6) is the tube of hollow and both ends open, its upper end places head fire hole (5) central authorities, leave enough slits on every side, burner head (4) drain pan is passed in the lower end, tube wall and drain pan sealing form the pipeline that auxiliary air passes through.

2, a kind of combustion gas tool burner according to claim 1, its feature is that also auxiliary air pipe (6) upper port protrudes on the head fire hole (5), its upper pipes shape meets head fire hole (5) shape, its lower port protrudes in outside burner head (4) drain pan, and the ledge caliber is expanded as bell mouth shape gradually.

3, a kind of combustion gas tool burner according to claim 1, its feature are that also auxiliary air pipe (6) can vertically also can tiltedly wear burner head (4).

4, a kind of combustion gas tool burner according to claim 1, its feature is that also auxiliary air pipe (6) is for adapting to the deformable of different combustion gas tool needs, head fire hole (5) distribution situation is pressed in auxiliary air pipe (6) upper end, a pipe is joined in one hole, the lower end can be kept to a pipe or more than the pipe, the middle air distribution (7) that places in the burner head (4) of using connects.
