Inside the windshield. The primary wind cover is placed in the hollow secondary wind cover and fixedly connected by brackets. There is an air inlet channel between the primary wind cover and the secondary wind cover. The upper opening of the windshield also constitutes the combustion head. Arranged air closing holes are arranged on the side wall of the inlet end of the primary air closing hood. Its advantages are reasonable design, simple structure, and sufficient oxygen supply, so that the gas can be fully burned, thereby improving the combustion efficiency, and achieving the effects of energy saving, environmental protection, and no pollution.

Description

high efficiency burner

technical field

The utility model belongs to a combustion device, in particular to a high-efficiency burner.

Background technique

Because gas is clean, thermal efficiency is high, environmental protection, so the various gas appliances that use gas are of a great variety, but existing household gas stove, burner mostly adopts the metal structure that is provided with inner and outer fire cover. This kind of structure generally has the flame combustion dispersion, insufficient combustion, and large heat loss. How to improve the gas combustion efficiency in the combustion process is the primary consideration of the burner. Due to the design and production defects of the popular gas stoves on the market, most of them have low combustion firepower, insufficient oxygen supply, insufficient combustion, and low thermal efficiency. , waste energy and pollute the environment.

Contents of the invention

The utility model aims at overcoming the deficiencies of the prior art, and provides a high-efficiency burner with sufficient combustion and energy saving.

The high-efficiency burner of the present utility model is made of intake pipe, nozzle, primary wind cover, secondary wind cover. Air intake pipe, nozzle and the end plate of the primary wind cover are coaxially fixed, and the secondary wind cover is coaxially fitted with the primary wind cover and fixedly connected by the support.

As a further improvement of the utility model, arranged air-closing holes are arranged on the side wall of the inlet end of the primary air-closing hood.

As a further improvement of the utility model, the end of the nozzle is provided with a spray screen.

As a further improvement of the utility model, the upper opening of the primary wind hood is sunk in the upper opening of the secondary air hood to form a combustion head.

The high-efficiency burner of the utility model has reasonable design, simple structure and sufficient oxygen supply, so that the gas can be fully burned, thereby improving the combustion efficiency, and achieving energy saving, environmental protection and no pollution.

Description of drawings

The accompanying drawing of the description is a schematic structural view of the high-efficiency burner of the present utility model.

Detailed ways

Example 1

The high-efficiency burner of the utility model is composed of an air intake pipe 1, a nozzle 2, a primary wind cover 3, and a secondary wind cover 4, and the air intake pipe 1, the nozzle 2 and the end plate 5 of the primary air cover 3 are coaxial Phase is fixed, the secondary combined wind cover 4 and primary combined wind cover 3 coaxial sets, and are fixedly connected by support 6. On the side wall of the inlet end of the primary wind-closing hood 3, arranged wind-closing holes 7 are arranged. The end of described nozzle 2 has injection screen hole 8.

Example 2

The high-efficiency burner of the present utility model is to be connected nozzle 2 by inlet pipe 1, has injection screen hole 8 at the end of nozzle 2, and the bottom end plate 5 of inlet pipe 1, nozzle 2 and primary wind cover 3 and its The coaxial core is fixed and placed in the primary wind cover 3 . The primary wind cover 3 is placed in the hollow secondary wind cover 4 and is fixedly connected by the bracket 6. There is an air inlet passage between the primary wind cover 3 and the secondary wind cover 4. The primary wind cover 3 The upper opening is sunk in the upper opening of the secondary wind cover 4 and constitutes the combustion head. On the side wall of the inlet end of the primary wind-closing hood 3, arranged wind-closing holes 7 are arranged.
