Embodiment 1

[0046]Example 1, such as Figure 1 to Figure 8 As shown, the main fire hole channel 5 is located on the upper side of the annular groove 4 , and the flame stabilizing fire hole channel 6 is connected to the main fire hole channel 5 by perforating from the annular groove 4 .

[0047] The main fire hole channel 5 gradually extends upwardly from the inside of the gas chamber 2, so that it is convenient to drill holes from the annular groove 4 to communicate with the main fire hole channel 5, so as to form the flame stabilizing hole Channel 6.

Embodiment 2

[0048] Example 2, such as Figure 9 to Figure 16 As shown, the main fire hole passage 5 is located on the lower side of the annular groove 4, and the flame stabilization fire hole passage 6 is connected to the gas chamber 2 by perforating upward from the end of the main fire hole passage 5 close to the gas chamber 2. Ring groove 4.

[0049] The main fire hole channel 5 gradually extends upwardly from the inside of the gas chamber 2, so that the drill bit can be easily inserted into the main fire hole channel 5, and the end close to the gas chamber 2 is drilled upwards to communicate with the annular groove. 4, to form the stable flame hole channel 6.

Abstract

The invention discloses a fire cover. According to the scheme, flame stabilizing fire hole channels communicate with main fire hole channels and do not directly communicate with the interior of a gascavity; according to the function of the flame stabilizing fire hole channels, part of gas entering the main fire hole channels from the gas cavity can flow into the flame stabilizing fire hole channels in a dividing manner, accordingly, on one hand, the gas flow of main fire hole channel outlets can be better reduced, and accordingly the phenomenon of arcing at the main fire hole channel outlet positions is reduced; and on the other hand, during work, flames combusting at the tail ends of the flame stabilizing fire hole channels can pull flames combusting at the main fire hole channel outletpositions, accordingly, the flame stabilizing function is achieved, and the flame stabilizing fire hole channels are good in practicability. In addition, according to the function of an annular groovein the scheme, air supplementing is conveniently conducted on the left side and the right side of each flame stabilizing fire hole channel outlet, the flames at the flame stabilizing fire hole channel outlet positions are better combusted towards the two sides of the annular groove, the transverse width of the stabilized flame fire is increased, and the flames combusting at the main fire hole channel outlet positions are better pulled.

Description

technical field [0001] The present invention relates to a fire cover. Background technique [0002] Due to the problem of flame stability, household gas stoves on the market are basically designed with flame stabilizing holes or flame stabilizing grooves, but the flame stabilizing effect of the existing flame stabilizing structure may not be good, which may affect thermal efficiency and flue gas. [0003] Therefore, how to overcome the above existing defects has become an important issue to be solved urgently by those skilled in the art. Contents of the invention [0004] The present invention overcomes the disadvantages of the above-mentioned technologies, and provides a fire cover with good practicability. [0005] To achieve the above object, the present invention adopts the following technical solutions: [0006] A fire cover, comprising an annular fire cover body 1, the annular fire cover body 1 is provided with a gas cavity 2 with an opening facing downward, and an...
