Abstract
An inner flame cover for domestic gas burners comprises an inner flame cover body. The inner flame cover comprises a downwardly open cylinder, radial flame holes formed in the upper portion of the cylinder, and a connector on the lower portion of the cylinder. The inner flame cover is characterized in that the outer peripheral surface of the part, above the connector, of the cylinder is provided with a circular groove, and a lower axial wall plate of the circular groove is provided with flame holes passing the lower wall plate. The inner flame cover with the structure has the advantages that the flame holes in the circular groove burn while the upper radial flame holes of the inner flame cover burn; the flame holes in the circular groove burn to pull the root of flame burning in the upper flame holes of the cylinder, so that separate flames from the inner flame cover are prevented; burning is sufficient, burning efficiency is improved, and energy is saved. A burner with the inner flame cover and radial gas guide channels; the radial guide channels spiral left or right, so that gas and air can be mixed well, the gas can burn sufficiently, and heating efficiency is improved.
