Wherein, be provided with on the locating plate 100 and draw the center of penetrating the fire chamber 201, the annular that is linked together with second and penetrates pipe 300 with first penetrating pipe 200 intercommunication and go out fire chamber 301, first penetrating pipe 200 runs through locating plate 100 and supports center and goes out fire chamber 201 and go out fire chamber 301 internal periphery central point department in the annular from locating plate 100 bottom, and second penetrates pipe 300 and runs through locating plate 100 and supports annular and go out fire chamber 301 and hang and locate locating plate 100 top. The first induction pipe 200 and the second induction pipe 300 are separated from each other and work independently of each other. An annular cavity 400 is arranged between the central fire outlet cavity 201 and the annular fire outlet cavity 301, an air supply channel 500 is communicated with the annular cavity 400, and the air supply channel 500 is formed by an overhead part enclosed among the second ejector pipe 300, the positioning plate 100 and the annular fire outlet cavity 301.

Through the structure, the gas in the furnace end flows to the center fire outlet cavity 201 through the first injection pipe 200, is sprayed out of the inner fire cover 600 covered on the center fire outlet cavity 201, and is ignited to be divergently to burn around the inner fire cover 600. The rest of the fuel gas flows to the annular fire outlet cavity 301 through the second injection pipe 300, is sprayed out of the outer fire cover 700 covered on the annular fire outlet cavity 301, and is ignited to burn around the outer fire cover 700. The annular flame outlet chamber 301 is arranged coaxially with the central flame outlet chamber 201 with an annular gap therebetween, which forms an annular chamber 400, wherein air can be stored in the annular chamber 400 for the second ignition of the gas in the annular flame outlet chamber 301 and the central flame outlet chamber 201. The air supply channel 500 is arranged on the circumferential direction of the positioning plate 100, the air supply channel 500 is surrounded by a bottom disc of the positioning plate 100, the lower end surface of the annular fire outlet cavity 301 and the arc-shaped communicating cavity 302, the air supply channel 500 is directly connected with the annular cavity 400, and a cavity capable of exchanging air with the outside is formed together.

When the gas stove works, the central fire outlet cavity 201 and the annular fire outlet cavity 301 spray flames through the fire outlet holes 701 in the fire cover, and part of the un-ignited gas is sprayed out through the fire outlet holes 701 due to insufficient oxygen content, the part of the gas and the oxygen in the annular cavity 500 can be mixed for the second time, the oxygen content of the gas is improved, so that the gas can be ignited by the flames for further combustion, the utilization efficiency of the gas stove head of the gas stove on the gas is improved, the loss of the gas is greatly reduced, in addition, the non-ignited gas is reduced by the secondary combustion of the gas stove head to be emitted to other spaces except for a working space, the probability that a user inhales the gas is avoided, and the health of the user is further guaranteed.

As shown in fig. 1, the alignment plate 100 has a disk-shaped structure at a bottom, and the disk-shaped structure has a semi-circular groove at a circumference. The second draws and penetrates behind the semi-annular groove that locating plate 100 runs through locating plate 100 to form the arc intercommunication chamber 302 that is used for supporting and communicates annular play fire chamber 301, and this arc intercommunication chamber 302 switches on with the semi-annular groove on locating plate 100 mutually, and the top of arc intercommunication chamber 302 switches on with the cavity that the annular goes out fire chamber 301 for the gas can enter into annular play fire chamber 301 from arc intercommunication chamber 302. The radian of the profile of the arc-shaped communicating cavity 302 is preferably 30-150 degrees, when the radian of the profile of the arc-shaped communicating cavity 302 is 45 degrees, the opening of the arc-shaped communicating cavity 302 is smaller, so that a larger pressure can be kept when fuel gas enters the annular fire outlet cavity 301 through the arc-shaped communicating cavity 302, the larger pressure can enable the distance of flame spraying to be longer, the coverage area of the flame is increased, the actual contact area of a pot bottom and the flame is increased, and the heat efficiency is improved. And when the profile radian of the arc communicating cavity 302 with a larger numerical value is selected, for example 135 degrees, the limitation of the size of the arc communicating cavity 302 on the gas ejection quantity can be reduced, and more gas can enter the annular fire outlet cavity 301 through the arc communicating cavity 302, so that the gas-fuel injection device is suitable for a working scene requiring larger flame, and in addition, the two arc communicating cavities can be comprehensively considered, and the radians with other numerical values, for example 75 degrees, 135 degrees and the like can be selected. Those skilled in the art can appropriately select the profile radian of the arc-shaped communication cavity 302 according to the actual use requirement and the actual working environment of the gas stove.

As shown in fig. 1, a support rib 304 for reinforcing the overhead portion is disposed between the positioning plate 100 and the annular fire outlet cavity 301, and two ends of the support rib 304 are respectively connected to the positioning plate 100 and the annular fire outlet cavity 301. The number of the support ribs 304 is reduced as much as possible on the basis of ensuring the strength of the whole structure, and the influence of excessive support ribs 304 on the air inlet rate of the air supply channel 500 is avoided.

Because the first injection pipe 200 and the second injection pipe 300 are horizontally arranged, and the axes of the central fire outlet cavity 201 and the annular fire outlet cavity 301 are perpendicular to the horizontal direction, the gas needs to be guided through the flow guide cavity wall 206(306) to be in transitional connection with the central fire outlet cavity 201 and the annular fire outlet cavity 301 through the first injection pipe 200 and the second injection pipe 300. The diversion cavity walls 206 and 306 are arranged in a form of extending obliquely upwards, and the gas enters the central fire outlet cavity 201 and the annular fire outlet cavity 301 along the oblique diversion cavity walls 206 and 306 through the injection pipe, so that the resistance of the gas in the flowing process is reduced, and the gas can flow smoothly. The projection profile of the diversion cavity wall 306 of the second injection pipe 300 along the direction perpendicular to the positioning plate 100 is matched with the profile radian of the arc-shaped communicating cavity 302, and stepped separation does not exist between the two, so that the gas can pass through more smoothly.

It should be noted that, the setting mode of the shielding portion 3073 is adapted to the arc-shaped communicating cavity 302 of the second injection pipe 300, the shielding portion 3073 should be able to cover the arc-shaped communicating cavity 302 entirely in the circumferential direction, when the profile radian of the arc-shaped communicating cavity 302 is large, the number of the step levels of the shielding portion 3073 can be increased appropriately, for example, when the profile radian of the arc-shaped communicating cavity 302 is 150 °, the third shielding portion and the fourth shielding portion may be further provided on the basis of the first shielding portion 3071 and the second shielding portion 3072 until the shielding portion 3073 is able to cover the arc-shaped communicating cavity 302 entirely. Alternatively, the existing shielding portion 3073 may be extended while keeping the number of step levels of the shielding portion 3073 constant, for example, the first shielding portion 3071 and the second shielding portion 3072 may be extended in the circular axis direction so that the shielding portion 3073 may entirely cover the arc-shaped communication chamber 302. Accordingly, when the curvature of the contour of the arc-shaped communication chamber 302 adopts a small curvature, a reduction in the number of step levels of the shielding portion 3073 or a compression in the extending length of the shielding portion 3073 can be adopted accordingly.
