[0032] A burner according to an embodiment of the present invention, the burner includes a burner head 1 and a combustion plate 2, the burner head 1 includes an air inlet housing 11 and a plurality of gas mixing housings 12, the air inlet housing 11 encloses to form an air inlet cavity, each gas mixing housing 12 encloses to form a gas mixing cavity communicating with the air inlet cavity, wherein, the plurality of gas mixing housings 12 are arranged at intervals along one side of the air inlet housing 11, and air outlet openings are formed on the opposite sides of any two adjacent gas mixing housings 12, the air inlet housing 11 is further provided with an air inlet opening, each gas mixing housing 12 communicates with the air inlet housing 11, the combustion plate 2 is connected to the air outlet openings, the number of the combustion plates 2 is the same as the number of the air outlet openings, and they correspond one by one.

[0033] Among them, the intake housing 11 and each air - fuel mixing housing 12 are both housing structures with cavities. Among them, the intake housing 11 encloses to form an intake cavity, and each air - fuel mixing housing 12 encloses to form an air - fuel mixing cavity communicating with the intake cavity. A plurality of air - fuel mixing housings 12 are arranged at intervals along the length direction of the intake housing 11. Here, the plurality of air - fuel mixing housings 12 can be evenly distributed on the same side of the intake housing 11 or not, and can be set according to different requirements.

[0034] Such as Figure 1 As shown, the combustion plates 2 are installed on the side walls of the opposite sides of two adjacent air - fuel mixing housings 12. An inverted U - shaped structure is formed between any two adjacent air - fuel mixing housings 12 and the intake housing 11. Since the combustion plates 2 are on the side walls of the air - fuel mixing housings 12, after the gas burns on the combustion plates 2, the hot air first enters the area between the two adjacent air - fuel mixing housings 12, and then heats the food on the top of the burner head 1. Because the heated air and carbon dioxide do not immediately rise and leave, the thermal efficiency of the burner is effectively improved.

[0035] In addition, since the combustion plates 2 are on the side walls of the air - fuel mixing housings 12, as long as the open end of the heating area is far from the direction of the cold air blowing, it can prevent the cold air from directly blowing on the combustion plates 2 and avoid the problem of flameout. It is suitable for indoor and outdoor use, with a wide range of applications and high user experience.

[0036] As shown in Fig. 5, a plurality of air - fuel mixing housings 12 can also be distributed on both sides of the intake housing 11, but the number of air - fuel mixing housings 12 on the same side is not less than two, and air outlets are opened on the opposite sides of two adjacent air - fuel mixing housings 12 on the same side. Then, an air inlet is opened in the width direction of the intake housing 11, and two air inlets can also be opened on the intake housing 11 according to needs to improve the air intake efficiency and air outlet effect. In this embodiment, the length direction refers to the direction where the long side of the intake housing 11 is located, and the width direction is the direction where the short side of the intake housing 11 is located.

[0037] In addition, the longitudinal section of the air - fuel mixing housing 12 can be a rectangular body, a trapezoidal body, a hexagon, an octagon, etc. Preferably, any two air - fuel mixing housings 12 have the same structure to ensure uniform air outlet of the two air - fuel mixing housings 12.

[0038] In a preferred embodiment of the present invention, the distance between any two adjacent air - fuel mixing housings 12 is 10 mm to 20 mm.

[0039] The number of air - fuel mixing housings 12 is 2 to 50. Figure 1-2 The schematic diagram when the number of air - fuel mixing housings 12 is two is shown. The number of air - fuel mixing housings 12 can also be 3, 4, 5, 6, 8, 10 or even more. One combustion area can be formed between any two adjacent air - fuel mixing housings 12, and different heating requirements for different foods can be set for each combustion area.

[0040] In addition, the distance between any two adjacent gas mixing housings 12 is 10 mm to 20 mm. By controlling the relative distance between two adjacent gas mixing housings 12, the escape of hot gas caused by an excessive relative distance between two adjacent gas mixing housings 12 is avoided, and the thermal efficiency of the burner is improved. The distance between two adjacent gas mixing housings 12 in the present application is the distance between the opposite sides of the two gas mixing housings 12.

[0041] In a preferred embodiment of the present invention, a plurality of gas mixing housings 12 are uniformly arranged along one side of the intake housing 11 to ensure uniform firepower in each combustion zone.

[0042] In a preferred embodiment of the present invention, the number of gas mixing housings 12 is not less than 3. The plurality of gas mixing housings 12 are divided into two first gas mixing housings 121 located at both ends of the intake housing 11 and at least one second gas mixing housing 122 located between the two first gas mixing housings 121; the burner head 1 includes a partition plate 6 inside the second gas mixing housing 122. One end of the partition plate 6 is connected to the side of the second gas mixing housing 122 away from the intake housing 11, and the other end of the partition plate 6 extends into the intake cavity and is connected to the intake housing 11; wherein, the intake housing 11 is divided by the partition plate 6 to form at least two independent intake zones, and each intake zone is respectively connected with an ejector tube 3 to control the intake condition of each intake zone.

[0043] For the convenience of better explaining the installation of the partition plate 6, the present application takes the number of gas mixing housings 12 as 3 as shown in Fig. 4. Since the combustion plates 2 can be installed on both sides of the middle second gas mixing housing 122, the second gas mixing housing 122 is divided into two independent parts by the partition plate 6. Specifically, one end of the partition plate 6 is connected to the side wall of the second gas mixing housing 122, and the other end of the partition plate 6 is extended into the intake cavity and connected to the intake housing 11. In this way, the partition plate 6 divides the entire second gas mixing housing 122 and the intake cavity into two parts. From the overall view, the partition plate 6 divides the burner head 1 into two independent combustion zones for intake and exhaust. The ejector tubes 3 can be installed in the two combustion zones respectively, that is, the independent control of the two combustion zones is realized, meeting the cooking requirements for food, and having a wide range of uses.

[0044] In a preferred embodiment of the present invention, one intake port is provided on one side of the intake housing 11, and the intake port is connected with an ejector tube 3.

[0047] As Figure 1-2As shown in the figure, when there are two mixing gas shells 12, only one ejector pipe 3 is provided for the burner head 1. The ejector pipe 3 can be arranged in the middle of the intake gas shell 11. The gas ejected by the ejector pipe 3 enters the two mixing gas shells 12 respectively through both ends of the intake gas shell 11, with uniform gas outlet and high thermal efficiency.

[0048] In a preferred embodiment of the present invention, there are three mixing gas shells 12, and the three mixing gas shells 12 and the intake gas shell 11 enclose an "E" - shaped structure.

[0049] The number of the mixing gas shells 12 can also be three, four or more. Among them, multiple mixing gas shells 12 are arranged at equal intervals along the intake gas shell 11. Taking the number of the mixing gas shells 12 being three as an example, the combustion plates 2 can be installed on both sides of the middle mixing gas shell 12. In this way, the middle mixing gas shell 12 can form two combustion zones with the two mixing gas shells 12. At this time, the ejector pipes 3 can be installed in the two combustion zones respectively, or one ejector pipe 3 can be installed. If separate control of the combustion zones is required, the above - mentioned partition plate 6 can be considered for partition setting.

[0050] As Figure 1 shown, in a preferred embodiment of the present invention, an oil - receiving tray 4 is further included, and the oil - receiving tray 4 is arranged at the bottom of the burner head 1. The oil - receiving tray 4 can receive oil stains and debris, which is convenient for users to clean and improves the user experience.
