The utility model is described below with reference to specific embodiments in conjunction with the accompanying drawings:

referring to fig. 1 to 3, an embodiment of the present utility model discloses a combustion device, which includes a combustion portion 100, wherein a combustion air passage 111, a first fire hole 112 and a second fire hole 113 are disposed in the combustion portion 100. The combustion device can be applied to a gas stove and other combustion equipment, and the utility model is not limited.

Wherein the combustion section 100 is a basic component of the combustion apparatus of the present utility model, the combustion section 100 may provide a mounting basis for other at least partial components of the combustion apparatus of the present utility model such that the other at least partial components of the combustion apparatus may be fixedly mounted. The combustion portion 100 may specifically include a distributor 110 and a fire cover 120, where the fire cover 120 may be covered on the distributor 110, the fire cover 120 and the distributor 110 may enclose to form a combustion air passage 111, fuel gas may be input into the combustion air passage 111 of the combustion portion 100, and the combustion air passage 111 of the combustion portion 100 may specifically be configured as an annular or circular structure, so that when the fuel gas is input into the combustion air passage 111 of the combustion portion 100, the fuel gas may be uniformly distributed along the circumferential direction of the combustion portion 100, and correspondingly, fire holes on the fire cover 120 may also be uniformly distributed along the circumferential direction of the combustion portion 100, so that flame formed after the fuel gas is ignited may be uniformly distributed.

In addition, the combustion device can be further provided with an injection pipe, one end of the injection pipe is communicated with the combustion air passage 111 of the combustion part 100, the other end of the injection pipe is connected with the fuel pipe, the fuel pipe can supply fuel gas to the injection pipe, and in the process of passing through the injection pipe, external air can be sucked by the injection pipe as primary air, so that mixed gas of fuel gas and air can be input into the combustion air passage 111.

The first fire hole 112 and the second fire hole 113 are open pore structures arranged on the surface of the combustion part 100, and the first fire hole 112 and the second fire hole 113 can be arranged on the side wall of combustion. Specifically, the first and second flame holes 112 and 113 are specifically through-hole structures formed in the side walls of the combustion portion 100, and one ends of the first and second flame holes 112 and 113 communicate with the combustion air duct 111, so that the other ends of the first and second flame holes 112 and 113 form openings on the outer side walls of the combustion portion 100. It should be understood that, when the combustion apparatus is used, the to-be-heated member, such as a pot, is placed on the combustion side 130 of the combustion portion 100, i.e. on one side end surface of the combustion portion 100, and when the first fire hole 112 and the second fire hole 113 are opened on the side wall of the combustion portion 100, the flow direction of the fuel gas discharged through the first fire hole 112 and the second fire hole 113 may be in a form of diverging to the outside of the combustion portion 100, so that the distributable range of the fuel gas is larger, and correspondingly, the range of the flame formed after the fuel gas is ignited is wider, so that the range of the heated portion of the to-be-heated member is larger, and thus the to-be-heated member may be heated relatively uniformly and sufficiently.

It should be appreciated that, after the fuel gas is discharged through the first and second flame holes 112 and 113, air located around the combustion portion 100 may be supplemented as secondary air to the fuel gas discharged from the first and second flame holes 112 and 113, so that the fuel gas may be combusted more sufficiently. It should also be appreciated that secondary air located near the first fire hole 112 is mainly supplemented to the fuel gas exhausted from the first fire hole 112, and secondary air located near the second fire hole 113 is mainly supplemented to the fuel gas exhausted from the second fire hole 113, and if the overlapping range of the surrounding spaces of the first fire hole 112 and the second fire hole 113 is large, that is, the distance between the first fire hole 112 and the second fire hole 113 is too small, the first fire hole 112 and the second fire hole 113 can "rob" gas, so that the amount of secondary air supplemented to the first fire hole 112 and the second fire hole 113 is insufficient, and finally, the fuel gas exhausted through the first fire hole 112 and the second fire hole 113 is insufficiently combusted to generate large smoke. However, if the distance between the first fire hole 112 and the second fire hole 113 is too large, the number of the first fire hole 112 and the second fire hole 113 that can be arranged on the combustion device is smaller, so that the combustion effect of the combustion device is affected.

In the present utility model, the extending direction of the first flame holes 112 may be set to be different from the extending direction of the second flame holes 113, that is, the extending direction of the first flame holes 112, that is, the direction from the end of the first flame holes 112 connected to the combustion air duct 111 to the end of the first flame holes 112 forming the opening on the combustion part 100, and the extending direction of the second flame holes 113, that is, the direction from the end of the second flame holes 113 connected to the combustion air duct 111 to the end of the second flame holes 113 forming the opening on the combustion part 100. Therefore, the flow directions of the fuel gas discharged through the first and second flame holes 112 and 113 are different, so that the fuel gas discharged through the first and second flame holes 112 and 113 can be diffused in different directions, and overlapping portions of ranges in which the first and second flame holes 112 and 113 are spatially distributed are relatively small, so that the fuel gas discharged through the first and second flame holes 112 and 113 can use secondary air in different regions in space, and the fuel gas discharged through the first and second flame holes 112 and 113 can be fully combusted.

In the combustion device provided by the embodiment of the utility model, the first fire holes 112 and the second fire holes 113 are formed in the side wall of the combustion part 100, so that the diffusion distribution range of the fuel gas discharged through the first fire holes 112 and the second fire holes 113 is larger, and the flame distribution range formed after the fuel gas is ignited is larger, thus the combustion device has better combustion effect. The extending directions of the first fire hole 112 and the second fire hole 113 are different, so that the distribution ranges of the fuel gas discharged through the first fire hole 112 and the second fire hole 113 in the space around the combustion part 100 are overlapped less, the fuel gas discharged through the first fire hole 112 and the second fire hole 113 can fully utilize secondary air in different space ranges around the combustion part 100, and the fuel gas discharged through the first fire hole 112 and the second fire hole 113 can fully burn, and finally, the combustion effect of the combustion device is better.

In some embodiments, referring to fig. 2 to 4, in order to make the heating effect of the combustion apparatus of the present utility model on the heating member more sufficient, the extending direction of the first fire hole 112 of the combustion portion 100 may be set to be biased toward the combustion side 130 of the combustion portion 100 with respect to the second fire hole 113, and correspondingly, the extending direction of the second fire hole 113 may be set to be biased toward the combustion side 130 of the combustion portion 100 with respect to the first fire hole 112. Specifically, since the first fire hole 112 is formed on the side wall of the combustion portion 100, and the extending direction of the first fire hole 112 is relatively biased towards the combustion side 130 of the combustion portion 100, an included angle between the extending direction of the second fire hole 113 and the axial direction of the combustion portion 100 is relatively large, so that the fuel gas discharged from the second fire hole 113 can be distributed along the radial direction of the combustion portion 100 relative to the fuel gas discharged from the first fire hole 112, and the fuel gas discharged from the second fire hole 113 can be fully dispersed and distributed in the circumferential space of the combustion portion 100, so that the air in the circumferential space of the combustion portion 100 can be fully utilized.

The second fire hole 113 is formed on the side wall of the combustion portion 100, and the extending direction of the second fire hole 113 is relatively deviated from the combustion side 130 of the combustion portion 100, so that an included angle between the extending direction of the first fire hole 113 and the axial direction of the combustion portion 100 is relatively smaller, and thus the fuel gas discharged from the first fire hole 112 can be distributed along the axial direction of the combustion portion 100 relative to the fuel gas discharged from the second fire hole 113, so that the fuel gas discharged from the first fire hole 112 can be relatively dispersed and distributed in the space at the combustion side 130 of the combustion portion 100, and the air in the space at the combustion side 130 of the combustion portion 100 can be fully utilized.

Specifically, when the to-be-heated member, such as a pot, is mounted above the combustion side 130 of the combustion portion 100, the gas discharged from the first flame holes 112 may be relatively more concentrated in the middle portion of the bottom of the pot, so that a flame generated by igniting the gas discharged from the first flame holes 112 may be formed in the middle portion of the combustion portion 100 to sufficiently heat the middle portion of the bottom of the pot. The gas discharged from the second flame holes 113 may be relatively more concentrated at the outer circumferential portion of the cooker such that flames formed by the ignition of the portion of the gas may be formed at the outer circumferential portion of the combustion part 100 to sufficiently heat the sidewall portion of the cooker such that both the side and bottom portions of the cooker may be sufficiently heated.

In some embodiments, referring to fig. 6, in order to allow the first flame holes 112 to be more toward the combustion side 130 of the combustion part 100 than the second flame holes 113 in the present utility model, the first flame holes 112 and the second flame holes 113 may be disposed to be inclined more than the second flame holes 113. When the combustion device of the present utility model is placed on a cooking bench, the bottom wall of the first fire hole 112 is located at one side of the bottom of the first fire hole 112, the bottom wall of the first fire hole 112 has a first included angle with a preset plane, and the preset plane is a virtual plane perpendicular to the axial direction of the combustion part 100, so that the preset plane is also opposite to the combustion side 130 of the combustion part 100, and the bottom wall of the first fire hole 112 is obliquely arranged relative to the preset plane, so that the bottom wall of the first fire hole 112 can guide the gas passing through the first fire hole 112, and the gas passing through the first fire hole 112 can flow along the bottom of the first fire hole 112, so as to achieve the purpose of controlling the flow direction of the gas.

The second fire hole 113 is also provided with a bottom wall opposite to the combustion side 130, when the combustion device is placed on the cooking bench, the bottom wall of the second fire hole 113 is positioned at one side of the bottom of the second fire hole 113, the bottom wall of the second fire hole 113 and a preset plane have a second included angle, and the preset plane is a virtual plane perpendicular to the axial direction of the combustion part 100, so that the preset plane is also opposite to the combustion side 130 of the combustion part 100, and the bottom wall of the second fire hole 113 is obliquely arranged relative to the preset plane, so that the bottom wall of the second fire hole 113 can guide gas passing through the second fire hole 113, and the gas passing through the second fire hole 113 can flow along the bottom of the second fire hole 113, so that the purpose of controlling the flow direction of the gas is achieved. The first included angle is larger than the second included angle, so that the bottom wall of the first fire hole 112 is deviated from the preset plane relative to the bottom wall of the second fire hole 113, and further, the bottom wall of the first fire hole 112 is deviated from the combustion side 130 of the combustion portion 100 relative to the bottom wall of the second fire hole 113, so that the fuel gas discharged through the first fire hole 112 can be relatively concentrated on the combustion side 130 of the combustion portion 100, and the fuel gas discharged through the second fire hole 113 is relatively concentrated on the peripheral portion of the combustion portion 100.

In some embodiments, referring to fig. 5, the gas in the first flame holes 112 is discharged through the openings formed in the surface of the combustion part 100 by the first flame holes 112, and the gas in the second flame holes 113 is discharged through the openings formed in the surface of the combustion part 100 by the second flame holes 113, so that the openings of the first flame holes 112 and the second flame holes 113 determine the initial positions of the gas discharged through the first flame holes 112 and the second flame holes 113. The first flame holes 112 and the combustion side 130 of the combustion portion 100 have a first distance, and the second flame holes 113 and the combustion side 130 of the combustion portion 100 have a second distance, where the first distance is equal to the second distance, so that the flame formed by igniting the fuel gas discharged through the first flame holes 112 and the second flame holes 113 has a relatively close height, so that the heating effect of the flame formed at the first flame holes 112 and the second flame holes 113 on the workpiece to be heated is relatively close.

In some embodiments, referring to fig. 1, 4 and 5, the number of the first fire holes 112 and the second fire holes 113 of the present utility model is plural, the first fire holes 112 may be distributed at intervals along the circumferential direction of the combustion part 100, and accordingly, the combustion air passages 111 of the combustion part 100 may be distributed along the circumferential direction of the combustion part 100, so that the first fire holes 112 may be in communication with the combustion air passages 111. Specifically, the combustion air path 111 may be configured in a ring shape, such that the fuel gas entering the combustion air path 111 may be distributed along the ring shape, so that the fuel gas may be relatively uniformly distributed in the combustion portion 100. The fuel gas discharged from the plurality of first flame holes 112 may be relatively uniformly distributed in each portion of the circumference of the combustion part 100, so that flames formed at the plurality of first flame holes 112 are distributed along the circumference of the combustion part 100. The plurality of second flame holes 113 may also be spaced apart along the circumferential direction of the combustion portion 100 such that flames formed at the plurality of second flame holes 113 may also be distributed along the circumferential direction of the combustion portion 100.

Specifically, the plurality of first fire holes 112 and the plurality of second fire holes 113 may be alternately arranged along the circumferential direction of the combustion portion 100, such that the two sides of the first fire holes 112 are the second fire holes 113, the two sides of the second fire holes 113 are the first fire holes 112, and the adjacent first fire holes 112 and second fire holes 113 maintain a certain distance, so that the first fire holes 112 and the second fire holes 113 may be relatively regularly arranged in the combustion portion 100. In addition, the first and second flame holes 112 and 113 may also sufficiently utilize the area of the surface of the combustion part 100 such that the number of the first and second flame holes 112 and 113 may be set relatively more while flames generated at the first and second flame holes 112 and 113 may also be continuously distributed in the circumferential direction of the combustion part 100. When the first and second flame holes 112 and 113 are adjacently disposed, since the first and second flame holes 112 and 113 correspond to secondary air in different spaces outside the combustion part 100, sufficient secondary air can be combustion-supporting gas discharged at the adjacently disposed first and second flame holes 112 and 113, so that the combustion effect of flames generated at the first and second flame holes 112 and 113 is better.

In some embodiments, referring to fig. 2 and 3, it should be appreciated that, since the first flame holes 112 are more toward the combustion side 130 of the combustion portion 100 than the second flame holes 113, the flame generated at the second flame holes 113 may be enclosed by the flame generated at the first flame holes 112, such that the combustion apparatus of the present utility model may generate a center flame and an outer ring flame. Further, it should also be understood that the space between the bottom of the member to be heated and the combustion portion 100 is a semi-closed space, and thus the amount of air in this space is relatively small, while the outer periphery of the member to be heated and the outer periphery of the combustion portion 100 are open spaces, and thus the amount of air in this space is relatively sufficient. In order to avoid that the gas discharged from the first fire hole 112 cannot be combusted sufficiently, the flow rate of the gas passing through the first fire hole 112 may be set to be smaller than the flow rate of the gas passing through the second fire hole 113, so that the amount of the gas passing through the first fire hole 112 is relatively small, thereby enabling the gas discharged from the first fire hole 112 to be combusted sufficiently with relatively small secondary air and reducing the amount of smoke. Since the gas discharged from the second flame holes 113 is distributed in the circumferential direction of the combustion part 100, the flow rate of the gas passing through the second flame holes 113 can be set to be relatively large, so that the amount of the gas discharged from the second flame holes 113 is relatively large, and the gas discharged from the second flame holes 113 can be combusted sufficiently under the condition that the secondary air is relatively sufficient, so that the flame generated at the second flame holes 113 is stronger in firepower, and the combustion device of the utility model has a better combustion effect and generates relatively less smoke.

Specifically, the first flame hole 112 has a first cross section in the extending direction of the first flame hole 112, the second flame hole 113 has a second cross section in the extending direction of the second flame hole 113, the first cross section is smaller than the second cross section, and if the first flame hole 112 and the second flame hole 113 are circular holes, the inner diameter of the first flame hole 112 is smaller than the second flame hole 113.

In some embodiments, referring to fig. 4-6, it should be appreciated that when the gas flow through the first flame holes 112 is less than the gas flow through the second flame holes 113, and accordingly, the flow rate of the gas through the first flame holes 112 is faster than the flow rate of the gas through the second flame holes 113, if the flow rate of the gas in the first flame holes 112 is too fast, the distance that the gas continues to flow after being discharged through the first flame holes 112 increases, and thus the gas is far from the first flame holes 112, so that the flame formed by the partial ignition is far from the combustion part 100, resulting in the occurrence of a flame-out phenomenon.

In order to prevent the combustion apparatus of the present utility model from generating the lifted flame phenomenon to some extent, it may be achieved by reducing the flow rate of the gas passing through the first flame holes 112. Specifically, the combustion portion 100 of the present utility model may further include a flame stabilizing hole 114, where the flame stabilizing hole 114 is disposed between the first flame hole 112 and the second flame hole 113, and the flame stabilizing hole 114 is also in communication with the combustion air duct 111, so that the gas in the combustion air duct 111 may be further input into the flame stabilizing hole 114, and thus the gas pressure in the combustion air duct 111 may be reduced to a certain extent, so as to reduce the flow rate of the gas passing through the first flame hole 112, and thus the flame formed after the gas discharged from the first flame hole 112 is ignited may be relatively close to the combustion portion 100. In addition, the flame stabilizing hole 114 is disposed adjacent to the first flame hole 112, so that the flow rate and the air pressure of the fuel gas entering the first flame hole 112 through the combustion air passage 111 can be further reduced, and the fuel gas discharged from the first flame hole 112 can be further ignited to form a flame near the combustion part 100.

Of course, the gas is ignited after being discharged through the flame stabilizing hole 114 to form flame, and the flame at the flame stabilizing hole 114 is adjacent to the first flame hole 112, so that the gas discharged from the first flame hole 112 can be more effectively ignited, and the gas discharged from the first flame hole 112 can be ignited without enlarging the distance between the gas and the combustion part 100, thereby alleviating the flame-off phenomenon of the combustion device of the present utility model to some extent.

In some embodiments, referring to fig. 5 and 6, in order to further reduce the possibility of the flame lift phenomenon of the combustion apparatus of the present utility model, the flame stabilizing hole 114 and the first flame hole 112 may be further disposed in a communicating state, so that a portion of the fuel gas passing through the first flame hole 112 may be further diffused into the flame stabilizing hole 114 to reduce the air pressure and the flow rate of the fuel gas passing through the first flame hole 112, so that the flow rate of the fuel gas discharged from the first flame hole 112 is not excessively fast. Part of the fuel gas in the flame stabilizing hole 114 can be diffused in the first flame hole 112, so that the air pressure and the flow rate of the fuel gas in the flame stabilizing hole 114 can be reduced, and the flow rate of the fuel gas discharged from the flame stabilizing hole 114 can not be too fast. In addition, the flame stabilizing hole 114 is communicated with the first flame hole 112, so that the fuel gas in the flame stabilizing hole 114 and the fuel gas in the first flame hole 112 can be mutually supplemented, and the fuel gas flow in the first flame hole 112 and the flame stabilizing hole 114 can be kept stable, and thus, the flame formed by igniting the fuel gas discharged from the first flame hole 112 and the flame stabilizing hole 114 is relatively stable.

In some embodiments, referring to fig. 6, in order to further reduce the flow rate of the gas in the flame holding hole 114, the flame holding hole 114 may be configured as an expanding structure, specifically, the flame holding hole 114 has one end communicating with the combustion air passage 111 and an opening opened at a side wall of the combustion part 100, and in a direction from one end of the flame holding hole 114 connected with the combustion air passage 111 to the opening end of the flame holding hole 114, the cross-sectional area of the flame holding hole 114 may be configured to gradually increase so that the flame holding hole 114 may gradually expand in the extending direction of the flame holding hole 114, and thus, the pressure of the gas passing through the flame holding hole 114 may gradually decrease and the flow rate of the gas may gradually decrease so that the distance that the gas discharged from the flame holding hole 114 continues to flow may be relatively small, and thus, the part of the gas may be ignited relatively close to the combustion part 100, so that the flame generated at the flame holding hole 114 may be prevented from being lifted. Specifically, in order to make the flame stabilizing hole 114 have an outward expansion structure with a gradually increased cross section, in the extending direction of the flame stabilizing hole 114, the distance between the two opposite side walls of the flame stabilizing hole 114 may be gradually increased, so that the two opposite side walls of the flame stabilizing hole 114 may play a role in guiding the fuel gas in the flame stabilizing hole 114, so that the fuel gas gradually diffuses in the process of flowing in the flame stabilizing hole 114, and thus the fuel gas discharged from the flame stabilizing hole 114 may sufficiently diffuse around the flame stabilizing hole 114 relatively, so as to play a sufficient flame stabilizing role on the fuel gas discharged from the first flame hole 112.

In some embodiments, referring to fig. 1, the combustion portion 100 of the present utility model may specifically include a fire cover 120 and a flame divider 110, where the fire cover 120 is covered on the flame divider 110, and the flame divider 110 has an open mouth structure therein, and the fire cover 120 is covered on the flame divider 110, and the fire cover 120 and the cavity in the flame divider 110 enclose a combustion air channel 111, a first fire hole 112, a second fire hole 113, and a flame stabilizing hole 114. Specifically, the opening of the first flame hole 112 may be formed on the sidewall of the distributor 110, and correspondingly, the opening of the second flame hole 113 and the opening of the flame stabilizing hole 114 may be formed on the sidewall of the distributor 110. When the combustion device is used for heating a piece to be heated, such as a cooker, the piece to be heated can be directly placed on the fire cover 120, so that the contact area between the piece to be heated and the fire cover 120 is larger, and the piece to be heated can be kept stable.
