Background

In the prior art, chinese patent 201921746726.4 discloses an upper air inlet multi-head gas burner, which is formed by connecting a distributor, a distributor seat plate and a distributor seat plate from top to bottom, wherein a central air hole is distributed on the upper end surface of the distributor seat plate, a plurality of air holes are arranged in an annular array around the central air hole, and the distributor is in threaded connection with the central air hole and the air holes on the distributor seat plate; the lower end face of the fire distribution base plate is provided with supporting legs and an air guide pipe, and the supporting legs are clamped with positioning convex blocks correspondingly arranged on the upper end face of the fire distribution base plate; the air duct is communicated with air holes distributed on the upper end face of the fire distribution seat plate and corresponds to an air nozzle arranged on the upper end face of the flow distribution seat plate, the flow distribution seat plate is provided with an annular air duct communicated with the central air duct, an air duct opening is connected with an air source, and a downward mounting support leg is arranged. The problems exist that: the distributor burns insufficiently and has low energy efficiency.

SUMMERY OF THE UTILITY MODEL

The purpose of the utility model is: the gas burner has the advantages of full combustion and high energy efficiency due to the arrangement of the main fire and the auxiliary fire.

The utility model is realized by the following steps: a gas burner head is characterized in that: it comprises an air inlet interface, a combustion cavity with an upper opening and a core body,

the core body comprises a main combustion hole arranged in the center and a plurality of axial gas grooves which are uniformly distributed;

the air inlet interface and the combustion cavity are integrally formed, the core body is arranged in the combustion cavity, the axial gas groove and the inner surface of the combustion cavity form an axial gas channel, the upper end of the axial gas channel is provided with an auxiliary combustion hole, and the lower end of the core body and the bottom plate of the combustion cavity form a premixing cavity.

The gas burner is characterized in that: the lower part of the combustion chamber is provided with a step which supports the lower end of the core body.

The gas burner is characterized in that: the upper end of the core body is provided with a head part, and the diameter of the head part is smaller than that of the core body;

the combustion ring is sleeved on the head, and the combustion ring and the axial gas groove on the head form the auxiliary combustion hole.

The gas burner is characterized in that: the air inlet interface, the combustion cavity with the upper opening and the core body are made of copper materials.

An upper air inlet cooking appliance burner is characterized by comprising a burner, a flow dividing seat, a central fire cover and the gas burning head.

According to the gas combustion head, due to the arrangement of the premixing cavity, gas and air are uniformly mixed, the main fire and the auxiliary fire are distinguished, secondary air is sufficient, combustion is sufficient, and the energy efficiency is improved; an upper air inlet cooking stove burner is sufficient in combustion and high in energy efficiency.

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1, a gas burner head 1 comprises an air inlet port 11, a combustion chamber 12 with an upper opening and a core body 2,

the core body 2 comprises a main combustion hole 21 arranged in the center and a plurality of axial gas grooves 22 which are uniformly distributed;

the air inlet connector 11 and the combustion chamber 12 are integrally formed, the core body 2 is arranged in the combustion chamber 12, the axial gas groove 22 and the inner surface of the combustion chamber 12 form an axial gas channel, the upper end of the axial gas channel is provided with an auxiliary combustion hole 23, and the lower end of the core body 2 and the bottom plate of the combustion chamber 12 form a premixing chamber 3. By adopting the structure, the mixed gas of the fuel gas and the air enters the premixing cavity 3 through the air inlet interface 11 and is fully mixed in the premixing cavity 3; premixing again in the lower part of the shaft gas and gas channel, and burning in the auxiliary burning hole 23; because the fuel gas and the air are uniformly mixed, the combustion is sufficient; the secondary air surrounds the auxiliary combustion holes 23, the secondary air is sufficient, no flying fire or yellow fire exists, and the energy efficiency is improved.
