Abstract

The utility model discloses a gas stove head, which comprises a gas nozzle and an air mixing pipe, wherein one end of the air mixing pipe is provided with a gas baffle plate overlapped with the gas nozzle and the end part of the gas nozzle is extended into an inner cavity of the air mixing pipe. A gas inlet hole is arranged on the wall of the air mixing pipe under the end part of the gas nozzle. The other end of the air mixing pipe is bent upwards. The top of the utility model is provided with a combusting mouth. The center of the top surface of the combusting mouth is provided with a combusting hole. The combusting mouth can be clamped on the inner circle surface of the air mixing pipe and can be sheathed on the outer circle wall of the air mixing pipe. The combusting mouth is made of fire-resistant materials. In gas stove heads using the structure, gas is mixed with air in the air mixing pipe after the gas is jetted from the gas nozzle and the gas is combusted on the top surface of the combusting mouth. The utility model can not generate carbon deposition and a tempering phenomenon. The utility model has the advantages of full gas combustion, safe use and simple structure. Besides, the use quantity of gas can be reduced, and the gas stove head can save gas by more than 30% compared with disk-shaped stove heads through experiments.

Description

A kind of gas burner

Technical field

The utility model relates to a kind of gas burner.

Background technology

Existing domestic gas burner, most twin-channel porous plate-like burners that have for making by metal material, the plate-like burner is provided with porous combustion fire cover, the drawback of this burner is: the combustion gas discharge port on combustion fire cover and the burner easily produces carbon distribution and stops up combustion gas discharge port, tempering phenomenon occurs, can cause security incident when serious.

Summary of the invention

The technical problems to be solved in the utility model provides a kind of simple in structure, not susceptible to plugging gas burner of fuel gas hole.

For solving the problems of the technologies described above, the utility model comprises gas nozzle and mixture pipe, its design feature is: an end of described mixture pipe is provided with the combustion gas baffle plate with the gas nozzle overlap joint, the end of gas nozzle extend in the mixture pipe inner chamber, has air admission hole on the tube wall of the mixture pipe below the gas nozzle end; The other end of mixture pipe is bending upwards, and its top is equipped with burner, and the end face center of burner is provided with burner port.

Described burner can be installed on the internal ring wall of mixture pipe, also can be sleeved on the external annulus of mixture pipe, and burner is made by refractory material.

After adopting said structure, combustion gas mixes with air in mixture pipe after the gas nozzle ejection, on the end face of burner, burn, form stable concentration field, temperature field, the fire combustion is stable, and fuel gas flow is unimpeded in the blast tube, air changes with the variation of gas flow, by the centre bore ejection of burner end face, therefore can not produce carbon distribution and tempering phenomenon occur, fuel gas buring is abundant, safe in utilization, simple in structure, and can reduce the combustion gas use amount, through test, the gas burner of this structure is saved combustion gas more than 30% than the plate-like burner.

Description of drawings

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail:

Fig. 1 is a cross-sectional view of the present utility model;

Fig. 2 is the cross-sectional view of the another kind of embodiment of the utility model;

Fig. 3 is the A-A cutaway view of Fig. 1.

The specific embodiment

With reference to accompanying drawing, this gas burner comprises gas nozzle 1 and mixture pipe 2, gas nozzle 1 is connected on the source of the gas, one end of described mixture pipe 2 is provided with the combustion gas baffle plate 5 with gas nozzle 1 overlap joint, this combustion gas baffle plate 5 extends downwards in the end of mixture pipe 2, make combustion gas can not release mixture pipe 2, the distance that the combustion gas baffle plate is stretched for 5 times is the 20%-25% of the internal diameter of mixture pipe 2, the end of gas nozzle 1 extend in mixture pipe 2 inner chambers, be the inboard that the end of gas nozzle 1 extend into combustion gas baffle plate 5, on the tube wall of the mixture pipe 2 below gas nozzle 1 end, have air admission hole 4; The other end of mixture pipe 2 is bending upwards, forms a vertical elbow, and its top is equipped with burner 3, and the end face center of burner 3 is provided with burner port 6.The burner 3 of gas burner shown in Figure 1 is installed on the internal ring wall of mixture pipe 2; The burner 3 of gas burner shown in Figure 2 is sleeved on the external annulus of mixture pipe 2.Burner 3 is made by refractory material, as refractory.
