After the sintering fire, the temperature of the thermal bulb 4e1 is reduced, the piston rod drives the thimble 4e3 to move upwards, and the spray hole is dredged, in order to assist the piston rod to move upwards, a pull rod 4e4 which is arranged in parallel with the thimble 4e3 is fixed on the horizontal rod 4e2, the tail end of the pull rod 4e4 penetrates through the outer part of the combustion tube and is provided with a spring seat, a first spring 4e5 is sleeved on the pull rod 4e4, and the first spring 4e5 is positioned between the spring seat and the combustion tube.

As shown in figure 9, an outlet of an oil inlet pipe 5 is communicated with an annularly-arranged preheating pipe 5a, the preheating pipe 5a is arranged above a fire grate 4, and an outlet of the preheating pipe 5a is communicated with a fuel branch pipe 5b and a fire grate feeding pipe 5 d. The grate feeding pipe 5d is communicated with at least one connecting end 4c, the fuel branch pipe 5b is provided with a spring type one-way valve 5c, the tail end of the fuel branch pipe 5b is provided with a plurality of oil spraying pipes 5b1, and the nozzles of the oil spraying pipes 5b1 face the thermal bulb 4e 1. As shown in fig. 10, a spring is arranged behind the blocking plate of the spring type check valve 5c, the opening needs to overcome the thrust of the spring, certain opening pressure is needed, and the opening pressure can be adjusted by rotating different springs.

The nozzle of the oil injection pipe 5b1 is provided with an ignition needle 6, the ignition needle 6 is fixedly connected with the inner wall of the furnace body 1 through a fixing rod 6b, the end face of the furnace body 1 is provided with a controller 6a, the inner wall of the furnace body 1 is fixed with a power supply device 6c, and the ignition needle 6 and the power supply device 6c are respectively electrically connected with the controller 6 a.

An outdoor cooking heating method comprises the following steps:

A. preheating: an oil outlet pipe of a pressurized gasoline tank is communicated with an oil inlet pipe 5, gasoline enters the inside of the oil inlet pipe 5 by rotating an adjusting valve of the gasoline tank, because the temperature of a thermal bulb 4e1 is low, a piston of the thermal bulb 4e1 pulls a horizontal rod 4e2 to move upwards, a spray hole of a combustion pipe is blocked by a thimble 4e3, and fuel entering the oil inlet pipe 5 cannot be sprayed out through the spray hole of the combustion pipe, so continuous pressure is carried out inside the oil inlet pipe 5, when the oil pressure is greater than the opening pressure of a one-way valve 5c, the fuel flows into a fuel branch pipe 5b and then is sprayed out through an oil injection pipe 5b1, an ignition needle 6 is used for ignition, and after the fuel is ignited, a heat radiation plate 3 and a thermal bulb 4e1 are heated;

B. and (3) igniting: the thermal bulb 4e1 is heated, the piston extends, the thimble 4e3 moves downwards, the spray hole of the combustion tube is opened, the fuel is sprayed and ignited through the spray hole, the oil pressure in the oil inlet tube 5 is reduced, and the one-way valve 5c is closed;

C. adjusting the flame direction: the nut sleeve 9 is rotated, the screw 8 moves in the direction away from the center of the furnace body 1, the rack 7 drives the first combustion pipe 4a to rotate through the moving gear 4a1, the first combustion pipe 4a drives the second combustion pipe 4b to rotate through the bevel gear 4d, and flame sprayed from the spray holes of the combustion pipes rotates towards the center of the heat radiation plate 3;

D. adjusting the size of the opening of the furnace plate: when the size of the heated vessel such as a pot is smaller than the opening of the furnace plate 2, the rotary plate 11 can be rotated, the arc-shaped plate 10 rotates around the rotating shaft 10a thereof, and the size of the middle opening of the necking module is adjusted;

E. cleaning spray holes of the combustion pipe: and closing the oil inlet of the oil inlet pipe 5, finishing combustion, cooling the thermal bulb 4e1, shrinking the piston rod, inserting the ejector pin 4e3 into the spray hole of the combustion pipe, dredging the spray hole and avoiding the spray hole from being blocked.

The embodiments of the present invention have been described in detail with reference to the drawings, but the present invention is not limited to the embodiments described above, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention.
