Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

As shown in fig. 1 to 3, the preferred embodiment of the present invention is shown. The burner fire cover for the gas stove comprises a fire cover body 1 and a gas mixing chamber 11 formed by the fire cover body 1, wherein a relatively isolated ignition chamber 2 is arranged in the gas mixing chamber 11, an air inlet 21 which is in fluid communication with the gas mixing chamber 11 is arranged on at least one wall of the ignition chamber 2, and an ignition hole 12 which is in fluid communication with the ignition chamber 2 is arranged at a position corresponding to the ignition chamber 2 of the fire cover body 1. The ignition chamber 2 is independent of the design of the gas mixing chamber 11, so that the excessive gas outlet speed of the ignition hole 12 can be prevented from causing flame separation; meanwhile, the thickness of the annular peripheral wall corresponding to the ignition hole 12 can be reduced, so that the depth of the ignition hole 12 can be correspondingly reduced, the ignition hole 12 is not easily blocked by overflowing liquid, in addition, the ignition chamber 2 forms a voltage stabilizing area at the ignition hole 12, the stable current of an ignition area can be ensured, the flame of the ignition hole 12 is stable, and the ignition success rate of the ignition hole 12 is improved.

An included angle alpha larger than 90 degrees is formed between the axis of the air inlet hole 21 and the central line of the ignition chamber 2, so that the gas in the ignition chamber 2 does not reach the ignition hole 12 from the air inlet hole 21 in a straight line, but the path is changed for one time by approaching 90 degrees, thereby reducing the gas speed of the ignition chamber 2, and in addition, the gas can be further uniformly mixed in the ignition chamber 2, and the stability of the gas is increased; for this reason, this structure makes it possible to enhance the ignition performance of the burner; even if the air source pressure of a user home is unstable and the combustion environment is poor, the method has good adaptability. In addition, the fire lid body 1 of the present embodiment includes an annular peripheral wall 13 and a lid body 14 covering the top opening of the annular peripheral wall 13, a flame holding channel 3 having a T-shaped cross section is extended toward the center of the inner wall of the annular peripheral wall 13, and the ignition chamber 2 is connected to the flame holding channel 3. This enables the flame stabilizing passage 3 to be independent of the gas mixing chamber 11 corresponding to the main flame hole, and can better independently perform flame stabilizing adjustment of the flame stabilizing holes 34 and also can be used as a connecting structure of the ignition chamber 2. The flame stabilizing channel 3 comprises a transverse part 31 arranged parallel to the cover body 14 and a vertical part 32 arranged parallel to the annular peripheral wall 13, a flame stabilizing chamber 33 is enclosed between the transverse part 31 and the cover body 14, and at least two flame stabilizing holes 34 communicated with the flame stabilizing channel 3 are formed in the position, corresponding to the flame stabilizing chamber 33, of the annular peripheral wall 13 of the fire cover body 1 along the circumferential direction. Because the flame stabilizing channel 3 comprises the vertical part 32 and the transverse part 31 communicated with the vertical part 32, namely the transverse part 31 is a diffusion chamber relative to the vertical part 32, the whole flame stabilizing space is equivalent to independently forming a flame stabilizing space in the gas mixing chamber 11, therefore, the flame stabilizing holes 34 can stabilize the flame of the ignition holes 12 at the same time of the main flame stabilizing holes, and the ignition success rate is further improved.

In order to improve the existing single main fire hole combustion mode, and the defects that the flame is easy to jump after combustion and the combustion area is unstable exist, the annular peripheral wall 13 of the fire cover body 1 of the embodiment is provided with a first main fire hole 15 and a second main fire hole 16 which are arranged in an upper row and a lower row at intervals along the circumferential direction at the position below the flame stabilizing hole 34, the annular peripheral wall 13 is circumferentially provided with a groove 17 between the first main fire hole 15 and the second main fire hole 16, the groove 17 is intersected with the first main fire hole 15, and the second main fire hole 16 is communicated with the groove 17. The annular peripheral wall 13 of the fire cover body 1 is provided with double rows of main fire holes, namely a first main fire hole 15 and a second main fire hole 16, a pressure stabilizing part formed by a groove 17 is arranged between the two rows of main fire holes, and the combustion efficiency of the gas stove can be obviously improved while the first main fire hole 15 and the second main fire hole 16 are stabilized. And, recess 17 is for inclining downwards and progressively from inside to outside keeping away from second main fire hole 16 from the upper end that communicates with first main fire hole 15 to the lower extreme that communicates with second main fire hole 16 to play better steady flame effect.

In summary, the burner cap for a gas stove comprises two gas flow paths, one of which is a flame stabilizing channel 3 that is independent from the gas mixing chamber 11, and the other is an ignition chamber 2 that is communicated with the gas mixing chamber 11 but can extend the gas flow path, by independently stabilizing the flame stabilizing holes 34 with the aid of the flame stabilizing channel 3, the flame can be better stabilized for the main flame holes, such as the first main flame hole 15 of the embodiment, and simultaneously, the flame can be stabilized for the ignition hole 12, and then the gas outflow time can be extended through the ignition chamber 2, thereby further improving the ignition success rate.
