It should be understood that, since the air groove 110 provided in the cover 100 is a groove structure formed on the surface of the cover 100, if the edge portion of the air groove 110 is directly connected to the first opening surface 120 of the cover 100, the air in the air groove 110 cannot smoothly flow to the first fire hole 121 of the first opening surface 120.

Therefore, the cover body 100 of the present application may further be provided with a first transition section 111, where the first transition section 111 is located between the first open hole surface 120 and the air slot 110, and the first transition section 111 communicates the first open hole surface 120 with the air slot 110, and has a transition structure, so that fluid can smoothly pass through the first transition section 111, and thus air in the air slot 110 can smoothly flow from the first transition section 111 to the first open hole surface 120, so that the efficiency of supplementing air in the air slot 110 to the first fire hole 121 is higher. Therefore, after the fuel gas is discharged through the first flame holes 121 and ignited, the air in the air tank 110 flows toward the first open hole surface 120 under the guide of the first transition section 111, thereby increasing the oxygen content of the mixed gas at the first flame holes 121.

In some embodiments, the air port 130 of the present application may be disposed through the cover 100, and in particular, the air port 130 penetrates through the cover 100 in the axial direction of the cover 100, such that the bottom side and the top side of the cover 100 are in communication. It should be understood that the distributor matched with the fire cover may be provided with a through hole structure corresponding to the air hole 130 of the cover 100, so that the air at the bottom of the gas stove may sequentially pass through the through hole of the distributor and the air hole 130 of the cover 100 to rise to the top side of the gas stove, and thus the air at the bottom of the gas stove may be supplemented into the air slot 110 of the cover 100, so that the amount of secondary air supplemented to the first fire hole 121 of the cover 100 is more sufficient.

It should be appreciated that when the mixed gas burns at the first fire hole 121 of the cover body 100, the temperature of the gas range itself and the temperature of the surrounding environment of the gas range are high, so that the temperature of the surrounding air of the gas range is high, and thus the air at the bottom of the gas range can rise up and flow to the first opening surface 120, and under the action of the pressure difference, the surrounding air continuously enters the air tank 110 to continuously supplement secondary air for the mixed gas burned at the first fire hole 121.

In addition, the air port 130 of the cover 100 may be specifically disposed at the center of the cover 100, and accordingly, the air port 130 and the cover 100 may be circular, that is, the air port 130 and the cover 100 are concentrically disposed, and of course, the air port 130 of the embodiment of the present application may also be other shapes, such as a lumbar circle, an oval, etc., which are not limited herein.

The plurality of first fire holes 121 may be distributed between the adjacent air slots 110, so that at least one first fire hole 121 is located between two adjacent air slots 110, and thus, the air slots 110 are disposed on both sides of the first fire holes 121, so that two air slots 110 can supplement secondary air to one first fire hole 121 at the same time, and further, fuel gas at the first fire holes 121 can be combusted more fully.

Specifically, the number of the first transition sections 111 and the first perforated surfaces 120 is also plural, the first perforated surfaces 120 are provided between two adjacent air slots 110, and the two air slots 110 are connected to the first perforated surface 120 located therebetween by the first transition sections 111. Therefore, the flame formed by the gas stove is more uniform in distribution, so that the heated piece is heated uniformly.

In some embodiments, in order to enable secondary air in the air port 130 to flow to the air tank 110 more smoothly, a second transition section 131 may be further disposed on the cover body 100 of the present application, where the second transition section 131 is specifically located between the air port 130 and the air tank 110, specifically, the second transition section 131 connects the inner wall of the air port 130 with the bottom wall of the air tank 110, and the second transition section 131 is also a transition structure, so that fluid can smoothly pass through the second transition section 131, and therefore, in the process of air flowing from the air port 130 to the air tank 110, the second transition section 131 can guide the flow of air, so that the air flowing from the air port 130 flows into the air tank 110 more easily, and further improving the supply speed of secondary air in the air tank 110.

The first transition section 111 and the second transition section 131 play a role in guiding the air flow, the first transition section 111 and the second transition section 131 can be provided with arc sections, the arc sections are gentler, no corner exists, the flow resistance in the air flowing process is smaller, and the air flowing speed can be accelerated.

Of course, in other embodiments, the first transition section 111 may be disposed as an inclined plane with respect to the inner wall of the air slot 110 and the first opening surface 120, and the second transition section 131 may be disposed as an inclined plane with respect to the inner wall of the air port 130 and the inner wall of the air slot 110, so that the first transition section 111 and the second transition section 131 also have an effect of guiding the air flow, and the specific structures of the first transition section 111 and the third transition section 131 are not limited, and the number of inclined planes may be also set as a plurality.

In some embodiments, the cover body 100 of the present application includes an inner ring portion 140 and an outer ring portion 150, where the inner ring portion 140 and the outer ring portion 150 are connected, the inner ring portion 140 and the outer ring portion 150 are annular structural members, the inner ring portion 140 encloses the air port 130, the outer ring portion 150 encloses the inner ring portion 140, and in the radial direction of the cover body 100, the thickness of the inner ring portion 140 in the axial direction of the cover body 100 is gradually increased, and the thickness of the outer ring portion 150 in the axial direction of the cover body 100 is gradually decreased. Thus, the end surfaces of the inner ring portion 140 and the outer ring portion 150 are inclined, so that when oil stains fall onto the cover body 100, the oil stains can slide along the inner ring portion 140 or the outer ring portion 150, and the oil stains are prevented from accumulating on the cover body 100 to block the first fire holes 121.

In some embodiments, the cover 100 is further provided with a second flame hole 161, and the mixed gas formed by mixing the air and the fuel gas can be discharged through the second flame hole 161 and ignited to form a flame at the cover 100. That is, flames can be formed at both the first flame holes 121 and the second flame holes 161, so that flames generated from the gas range can be more vigorous.

Specifically, the second flame holes 161 may be disposed in the inner ring portion 140 of the cover body 100, so that when the mixed gas burns in the second flame holes 161, the air flowing out of the air ports 130 may directly participate in the combustion of the mixed gas in the second flame holes 161, thereby supplementing secondary air to the mixed gas in the second flame holes 161, and fully combusting the mixed gas in the second flame holes 161.

In some embodiments, the inner ring portion 140 has a second hole surface 160 for forming a second fire hole 161, where the second hole surface 160 is connected to the first hole surface 120, that is, the air flowing out from the air port 130 passes through the second hole surface 160, supplements secondary air for the mixed fuel gas at the second fire hole 161, and then flows directly to the first hole surface 120 to supplement secondary air for the mixed fuel gas at the first fire hole 121, so that the mixed fuel gas at the first fire hole 121 and the second fire hole 161 can be fully combusted in an oxygen-enriched environment.

In some embodiments, the second fire hole 161 on the cover body 100 of the present application may be arranged in a staggered manner with the air groove 110, so that a stream of secondary air output by the air port 130 may not pass through the second fire hole 161 in the process of sequentially flowing through the second transition section 131 and the second open hole surface 160 into the air groove 110, so that the fuel gas output by the second fire hole 161 may be prevented from interfering with the stream of air, so that the stream of air may fully enter into the air groove 110 and supplement to the first fire hole 121, and finally, the fuel gas at the first fire hole 121 and the second fire hole 161 may be fully combusted.

In some embodiments, in order to make the combustion effect of the gas cooker using the fire cover of the present application better, the first fire holes 121 of the cover body 100 may be further disposed to be distributed along the direction from the air ports 130 of the cover body 100 to the edge of the cover body 100, so that the length dimension of the first fire holes 121 is longer, and the amount of fuel gas that can be discharged through the first fire holes 121 per unit time is greater, so that the fuel gas at the first fire holes 121 can form the fire cover distributed along the circumferential direction of the cover body 100 and along the radial direction of the fire cover 100 after being ignited, thereby making the gas cooker have better combustion effect. Correspondingly, the air groove 110 of the cover body 100 may also be disposed along a radial direction of the cover body 100, specifically, one end of the air groove 110 facing away from the air port 130 may be disposed at an edge of the cover body 100, and the first transition section 111 may also be disposed along a radial direction of the cover body 100, so that a length of the air groove 110 may be matched with a length of the first fire hole 121, and further, air in the air groove 110 may be supplemented to each portion of the first fire hole 121, so that fuel gas in each portion of the first fire hole 121 may be fully combusted.

Of course, the number of the first fire holes 121 may be plural, and the plurality of the first fire holes 121 may be distributed along the direction from the air port 130 of the cover 100 to the edge of the cover 100. The first fire holes 121 may be provided in more than one row, and the plurality of first fire holes 121 in each row are spaced apart in the radial direction of the outer ring portion 150. Specifically, the first fire holes 121 may be provided in two rows, so that two air slots 110 disposed adjacent to the first fire holes 121 may mainly supplement secondary air to one row of the first fire holes 121 on the same side, respectively, so that the mixed fuel gas at the two rows of the first fire holes 121 is fully combusted.
