Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

The first embodiment is as follows: as shown in fig. 1, 2, 3 and 4, the present embodiment provides a fire cover for a gas cooker, including a circular ring-shaped main body 1, where the main body 1 includes an upper panel 11, an inner side plate 12 extending downward from an inner edge of the upper panel 11, and an outer side plate 13 extending downward from an outer edge of the upper panel 11, a gas chamber 10 with an open bottom is formed between the upper panel 11, the inner side plate 12 and the outer side plate 13, 6 continuously fluctuating slope sections 110 are formed on the upper panel 11, 4 fire outlets 111 are provided on each slope section 110, the fire outlets 111 are long and have a length of 32mm to 38mm and a width of 0.8mm to 1.2mm, a connecting line L1 is formed between a center of the fire outlet 111 and a center of the main body 1, an included angle a1 between the fire outlet 111 and the connecting line L1 is 50 ° to 55 °, and the fire outlets 111 are inclined in a radial direction of the main body 1 so that the fire outlets 111 can be arranged in the radial direction of the main body 1 The length of the fire holes 111 is extended within the limited width of the panel 11 to increase the area of the single fire hole 111. In this embodiment, the fire hole 111 has a length of 35mm and a width of 1.0 mm. Of course, the length and width of the fire hole 111 can be modified by adapting the fire cover with different sizes.

The fire lid of this embodiment, through the reasonable overall arrangement that sets up out fire hole 111, increases the area of a single fire hole 111, and to a certain extent, the total area of multiplicable fire hole 111 makes the gas combustion of fire hole department more abundant from this, and combustion efficiency is higher, and then promotes the combustion efficiency of fire lid.

Furthermore, the fire holes 111 at least partially extend to the outer plate 13, so that the area of a single fire hole 111 can be increased, and the gas sprayed out through the fire holes 111 can be more fully mixed with the air outside the main body 1, thereby achieving the purposes of more fully combusting the gas and improving the combustion efficiency.

In this embodiment, an included angle a2 between two adjacent fire holes 111 on each slope surface section 110 is 10 ° to 15 °, specifically, an included angle a2 between two adjacent fire holes 111 is 13 °, so that two adjacent fire holes 111 can be fully combusted.

Preferably, the included angle A3 between the fire outlet 111 and the horizontal plane is 50 ° to 60 °, in this embodiment, the included angle A3 between the fire outlet 111 and the horizontal plane is 55 °, so that the gas at the fire outlet 111 can be combusted more sufficiently, the combustion efficiency is higher, and the combustion efficiency of the fire cover is further improved.

Specifically, the internal diameter of main part 1 is 80mm to 85mm, and the external diameter is 112mm to 118mm, and the height is 9mm to 12mm, and the degree of depth of gas chamber is 6mm to 7 mm. In this embodiment, the main body 1 has an inner diameter of 82mm, an outer diameter of 115mm, a height of 10.5mm, and a depth of 6.5 mm.

In addition, the included angle between the slope surface section 110 and the horizontal plane is 8-12 degrees. In this embodiment, the included angle between the slope surface section 110 and the horizontal plane is 10 °. Because the existence of slope makes gas chamber 10 form the continuous undulation of crest form, forms the combustion pressure differential, is favorable to the air to enter into gas chamber 10 and carries out more abundant mixture for difficult flame that leaves when the fire lid burning, the steady flame is effectual.

Further, the main body 1 is integrally formed by pressing a stainless steel plate, and the stainless steel plate can be selected from SUS304, SUS316, SUS201, SUS430 or SUS409L, wherein the thickness of the stainless steel plate is 2.5mm to 3.5mm, and specifically, the thickness of the stainless steel plate is 3.0 mm. During production, the stainless steel plate is placed on the hardware stamping die to be operated on the stamping machine, so that the operation can be completed, and the stainless steel plate stamping die is compact and firm in structure, not easy to deform, good in working stability and safety, convenient to assemble, long in service life, low in cost, and high in manufacturing yield and production efficiency.

Preferably, the outer side surface of the lower end of the outer side plate 13 is provided with a clamping position 130, so that the main body 1 can be conveniently installed on the furnace head, the installation efficiency of the main body 1 is improved, and the installation reliability of the clamping installation mode is relatively higher.

More preferably, a high temperature resistant coating is provided on the surface of the main body 1, so that the stability and safety of the fire cover operation can be improved, and the service life of the fire cover can be prolonged.

What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
