DETAILED DESCRIPTION

[0014] The present invention will be further described below in conjunction with the accompanying drawings.

[0015] refer to Figure 1 , Figure 2 and Figure 3 As shown, the embodiment of the present invention is a fully premixed new energy commercial burner, which includes a fire cover 10, on which a circle of first burners 11 are arranged, and the first burners 11 have the same rotation direction, and a drain hole 12 is arranged downwardly from the center of the fire cover 10, and a circle of second burners 13 is arranged on the outer circle of the upper side of the drain hole 12, and the rotation direction of the second burners 13 is consistent with that of the first burners 11; The fire cover seat 20 is used to carry the fire cover 10. A plurality of atomizer tubes 21 are evenly arranged on the outer circle of the fire cover seat 20. An air inlet hole 22 is arranged between every two atomizer tubes 21. The fuel tank 30 is used to support the fire cover seat 20. The fuel is mixed with air in the fuel tank 30 and then sprayed upward from the fire cover 10 through the atomizer pipe 21 to burn; The wind tube 40 passes through the center of the bottom of the oil tank 30 and extends into the oil tank 30. The top and bottom of the wind tube 40 are both provided with wind tube sealing plates 41 to close the wind tube 40. The upper part of the wind tube 40 is located in the oil tank 30 and a plurality of air outlet holes 42 are provided on the side. The lower part of the wind tube 40 is located outside the bottom of the oil tank 30 and a fan connecting pipe 43 communicating with the wind tube 40 is provided on the side. The sewage pipe 50 passes through the central closed hole 44 of the upper and lower air duct sealing plates 41 and is tightly arranged. A through hole 23 corresponding to the sewage hole 12 is arranged in the center of the fire cover seat 20. The top end of the sewage pipe 50 passes through the through hole 23 and is fixed in the sewage hole 12.

[0016] The main points of the present invention are that the fire cover 10 adopts an upper and lower layer of burners, the second burner 13 located at the center is directed upward, and the first burner 11 on the periphery is directed upward and inward. When burning, the flame is in a rotating state and can pull the gas in the center to flow upward together. The two are superimposed, and the firepower is stronger; the burner has at least six atomizer pipes 21 entering the furnace cavity, and the blower supplies air to the oil tank 30 through the horizontal fan connecting pipe 43. A plurality of air outlet holes 42 are provided on the upper side of the air duct 40 of the oil tank 30. After the wind passes through the plurality of air outlet holes 42, it passes through the air inlet holes 22 on the fire cover seat 20 and the through holes 23 of the fire cover seat 20. The gap between the drain pipe 50 and the gas enters the furnace cavity, disturbing the gas and helping the mixed gas to flow upward. In addition, the drain pipe 50 located at the center of the fire cover 10 directly takes air from the room to supplement secondary air to the center of the flame, making the combustion more complete and the heat load and thermal efficiency higher. The water vapor in the combustion products, the condensed water at the bottom of the pot and the smoke and dust impurities attached to them flow to the drain pipe 50 for direct discharge to avoid blockage of the fire cover fire mouth. There is an angle between the length direction and the radius direction of the fire mouth. Compared with the fire mouth facing the axis, the fire mouth is longer and the adjacent fire mouths are closer, which is more conducive to fire transfer. The heating area of ​​the bottom of the pot is larger and more uniform, and the cooking efficiency is higher.

[0017] In some embodiments, there are at least six atomizer tubes 21, which are evenly arranged on the outer circle of the fire cover seat 20. The multiple-tube design can ensure more uniform combustion of fuel.

[0018] In some embodiments, the atomizer tubes 21 are all tilted in one direction, so that the direction of the airflow can be controlled. Tilting in one direction can naturally produce a swirl fire, which can reduce the chance of gas and flame escaping.

[0019] In some embodiments, the inner side of the top of the outer ring of the fire cover seat 20 is recessed inward to form a fire cover seat receiving groove 24, and the bottom of the outer ring of the fire cover 10 is provided with a fire cover joint edge 14 correspondingly embedded in the fire cover seat receiving groove 24. The fire cover 10 is tightly fitted into the fire cover seat receiving groove 24 through the fire cover joint edge 14 and is arranged on the fire cover seat 20, so that the fire cover 10 can be easily removed from the fire cover seat 20, which is convenient for replacement or cleaning. Of course, the fire cover joint edge 14 can also be glued to the fire cover seat receiving groove 24 by glue to firmly fix the connection.

[0020] In some embodiments, the outer bottom of the outer ring of the fire cover seat 20 is provided with a fire cover seat clamping edge 25 extending downward, and the outer top of the outer ring of the fuel tank 30 is recessed inward to provide a corresponding fuel tank engaging groove 31 embedded in the fire cover seat clamping edge 25. The fire cover seat 20 is tightly fitted with the fuel tank engaging groove 31 through the fire cover seat clamping edge 25 and is arranged on the fuel tank 30. This is also convenient for disassembly. The fire cover seat 20 can be disassembled for easy replacement or cleaning, and the fuel tank 30 can also be cleaned at the same time. Of course, it can also be firmly fixed and connected by glue.

[0021] Furthermore, in some embodiments, in order to facilitate the installation of the burner, a support portion 60 is fixedly provided on the outer side of the fire cover seat 20, and the support portion 60 is used to support the installation of the burner to facilitate the coordinated use of the burner and the stove.

[0022] In some embodiments, the support portion 60 includes a support panel 61 fixed to the outside of the fire cover seat 20, and a support base plate 62 fixedly arranged on the lower side of the support panel 61. A groove corresponding to the support base plate 62 can be designed on the stove, so that the burner can be easily installed on the stove and can also be easily disassembled, which is convenient for later maintenance, replacement or cleaning.
