[0038] like Figure 1 Combination Figure 2 As shown, the utility model provides a furnace head mechanism, including a furnace body 1, a first partition 2 and a second partition 3; a first ejector tube 103, a second ejector tube 104 and an outer ring premixing chamber are formed on the furnace body 1, the first partition 2 and the second partition 3 are both arranged in the outer ring premixing chamber, and the first partition 2 and the second partition 3 divide the outer ring premixing chamber into a first mixing chamber 4, a second mixing chamber 5 and an outer ring mixing chamber 6; one end of the first mixing chamber 4 is connected to the air inlet of the first ejector tube 103, and the other end is connected to the outer ring mixing chamber 6, one end of the second mixing chamber 5 is connected to the air inlet of the second ejector tube 104, and the other end is connected to the outer ring mixing chamber 6.

[0039] Compared with the prior art, the burner head mechanism provided by the utility model has the following advantages:

[0040] The burner head mechanism provided by the utility model can cooperate with the furnace body 1 to form an annular side wall of the outer ring mixing chamber 6 by arranging the first partition 2 and the second partition 3 in the outer ring premixing chamber of the furnace body 1, thereby forming the above-mentioned first mixing chamber 4 and second mixing chamber 5, and the first mixing chamber 4 and the second mixing chamber 5 in the present application are independent of each other and not connected to each other.

[0041] By connecting one end of the first mixing chamber 4 to the first ejector tube 103 and the other end to the outer ring mixing chamber 6, the gas entering from the first ejector tube 103 can flow into the first mixing chamber 4 and flow into the outer ring mixing chamber 6 from the outlet of the first mixing chamber 4. Correspondingly, by connecting one end of the second mixing chamber 5 to the second ejector tube 104 and the other end of the second mixing chamber 5 to the outer ring mixing chamber 6, the gas entering from the second ejector tube 104 can flow into the second mixing chamber 5 and flow into the outer ring mixing chamber 6 from the outlet of the second mixing chamber 5, that is, the gas entering from the first ejector tube 103 and the gas entering from the second ejector tube 104 in the present application can flow for a distance in two independent spaces and then merge in the outer ring mixing chamber 6, thereby eliminating the problem of the existing burner structure that the gas is prone to collision when entering, resulting in poor gas uniformity, so that the gas can be more uniform in the outer ring mixing chamber 6, and the flow rate is more stable when meeting, thereby improving the uniformity and flame quality of the formed flame.

[0042] It should be noted here that the above-mentioned premixing chamber in the present application is a chamber formed by the inner ring wall 101, the outer ring wall 102 and the bottom surface of the furnace body 1 itself, and the first mixing chamber 4, the second mixing chamber 5 and the outer ring mixing chamber 6 are all formed based on the premixing chamber being separated by the first partition 2 and the second partition 3.

[0043] Alternatively, if Figure 1 Combination Figure 2 and Figure 4 As shown, the first partition 2 in the present application is located below the second partition 3, and the first partition 2 is arc-shaped, and the curvature of the first partition 2 is adapted to the outer ring premixing chamber; the second partition 3 includes a partition portion 301 and a baffle portion 302, and the second mixing chamber 5 is formed by the partition portion 301, the baffle portion 302, the first partition 2, the inner ring wall 101 and the outer ring wall 102 of the outer ring premixing chamber.

[0044] It is understandable that if Figure 5 As shown, since the first ejector tube 103 and the second ejector tube 104 are arranged in parallel in the present application, in order to ensure the formation of the second mixing chamber 5 and the smooth entry of the fuel gas through the second ejector tube 104, a slope section 201 is formed at one end of the first partition 2 close to the second ejector tube 104 in the present application, and the end 2011 of the slope section 201 is not higher than the bottom surface of the second ejector tube 104, so that an independent second mixing chamber 5 can be formed through the first partition 2, the second partition 3 and the inner ring wall 101 and the outer ring wall 102 of the furnace body 1 itself, so that the fuel gas ejected from the second ejector tube 104 can enter the second mixing chamber 5 and enter the outer ring mixing chamber 6 from the second gas outlet 501 of the second mixing chamber 5.

[0045] Accordingly, since the area between the inner ring wall 101 and the outer ring wall 102 in the present application is occupied as the second mixing chamber 5, the first mixing chamber 4 in the present application is located at the periphery of the second mixing chamber 5, that is, the first mixing chamber 4 bypasses the position of the second mixing chamber 5 and is formed along the outer ring of the second mixing chamber 5. Since the first partition 2 in the present application needs to form the first mixing chamber 4 and the outer ring mixing chamber 6 at the same time, and cooperate with the second partition 3 to form the second mixing chamber 5, the first partition 2 in the present application has an arc-shaped structure, and as shown Figure 5 As shown, the head end 2012 of the slope section 201 formed by the first partition 2 is not lower than the top surface of the first ejector tube 103 , so that the first ejector tube 103 and the second ejector tube 104 can be separated into the first mixing chamber 4 and the second mixing chamber 5 .

[0046] Correspondingly, one end of the first partition 2 away from the slope section 201 is in contact with the bottom surface of the premixing chamber of the furnace body 1, that is, Figure 1 As shown, the first partition 2 in the present application gradually decreases in height from the head end 2012 of the slope section 201 to the end away from the slope section 201 between the inner ring wall 101 and the outer ring wall 102 of the furnace body 1, so that the gas flowing out of the first gas outlet 401 of the first mixing chamber 4 can smoothly transition to the outer ring mixing chamber 6.

[0047] Preferably, if Figure 1 Combination Figure 3As shown, in the present application, the furnace body 1 is formed with a guide slope 107 at the position corresponding to the first gas outlet 401, and when the furnace body 1 forms the guide slope 107, the first partition 2 can be connected with the highest point of the guide slope 107, so that the gas flowing out of the first gas outlet 401 can smoothly transition to the first partition 2 through the guide slope 107, that is, enter the outer ring mixing chamber 6. And the formed guide slope 107 enables all positions of the first partition 2 in the present application to be located at the same horizontal height between the outer ring wall 102 and the inner ring wall 101, that is, the first partition 2 does not have any inclination relative to the horizontal plane, so that the gas flowing out of the first gas outlet 401 and the gas flowing out of the second gas outlet 501 can flow and mix in the space of the balanced outer ring mixing chamber 6, ensuring the uniform distribution of the gas.

[0048] Optionally, since it is difficult for gas to enter the area where the second partition 3 is arranged, Figure 1 As shown, the present application forms a plurality of gas outlet holes 3011 on the partition portion 301, so that part of the fuel gas can flow to the upper part of the partition portion 301 through the gas outlet holes 3011, thereby replenishing the fuel gas for the upper area of ​​the partition portion 301, so that the fuel gas can be evenly distributed along the circumferential direction in the furnace body 1, thereby ensuring the uniformity of the flame to a certain extent.

[0049] It is understandable that if Figure 1 As shown, in the present application, the end of the first mixing chamber 4 away from the first ejector tube 103 is the first air outlet 401, the end of the second mixing chamber 5 away from the baffle portion 302 is the second air outlet 501, and the first air outlet 401 is located on the side of the baffle portion 302 away from the second air outlet 501.

[0050] Alternatively, if Figure 1 Combination Figure 3 As shown, the burner head mechanism provided by the utility model further includes a third ejector tube 105 and an inner ring premixing chamber 106 , and one end of the third ejector tube 105 is connected to the inner ring premixing chamber 106 .

[0051] The third ejector tube 105 and the inner ring premixing chamber 106 formed on the furnace body 1 can provide a basis for the burner to form an inner ring fire.

[0052] Accordingly, if Figure 2-Figure 4 As shown, the burner head mechanism provided in the present application further includes an inner fire cover 7 and an outer fire cover 8. The inner fire cover 7 corresponds to the inner ring premixing chamber 106, and the outer fire cover 8 corresponds to the outer ring premixing chamber.

[0053] It can be understood that multiple exhaust holes are formed on the inner fire cover 7 and the outer fire cover 8 in the present application, and the multiple exhaust holes are evenly distributed along the circumference of the inner fire cover 7 and the outer fire cover 8, so as to form a uniform flame shape, ensure the flame quality, improve cooking efficiency, and enhance user experience.

[0054] In addition, the utility model also provides a burner, including a nozzle seat 9 and the above-mentioned burner head mechanism, wherein the burner head mechanism is located on the nozzle seat 9 and is detachably connected to the nozzle seat 9.

[0055] The burner of the burner head mechanism provided in the present application can provide a stable gas supply to the burner head mechanism through the nozzle seat 9, and after the gas enters the burner head mechanism, it can be distributed more evenly, so that during operation, the flame formed on the burner head mechanism can be more uniform and the flame effect can be better.

[0056] It can be understood that a plurality of nozzle columns 901 are formed on the nozzle seat 9 in the present application, and nozzles are connected to the nozzle columns 901. Accordingly, a gas inlet 902 is also formed on the nozzle seat 9 corresponding to the nozzle column 901. The gas enters through the gas inlet 902, passes through the nozzle column 901 to reach the nozzle, is ejected through the nozzle and can enter the corresponding first ejector tube 103, the second ejector tube 104 and the third ejector tube 105, thereby realizing the gas supply to the furnace body 1.

[0057] In addition, the utility model also provides a stove, comprising the above-mentioned burner.

[0058] The stove using the burner provided in the present application can provide a more uniform and higher quality flame state, thereby improving cooking efficiency and enhancing the user experience to a certain extent.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
