[0001] This utility model relates to the field of burner technology, specifically to a gas burner that ensures complete combustion. Background Technology

[0002] A gas burner is a device that mixes gas and air, ignites it under specific conditions, and maintains stable combustion. It is widely used in industrial heating, boilers, kilns, heat treatment equipment, and other fields.

[0003] In existing gas burners, gas and air are generally mixed and burned directly at the burner nozzle. The uneven mixing of gas and air leads to incomplete combustion of gas and easily produces a large amount of pollutants. Utility Model Content

[0004] The purpose of this invention is to provide a gas burner that ensures complete combustion, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a gas burner with complete combustion, comprising a burner body and a wind box disposed on the burner body. A motor is installed on the outer side of the burner body, and an impeller is connected to the output end of the motor. A combustion head is provided at one end of the burner body, and a gas pipe is provided inside the combustion head. A rotating rod is rotatably installed on the gas pipe, one end of which extends to the outer side of the gas pipe, and a fan is installed at one end of the rotating rod. A stirring blade is installed at the other end of the rotating rod. An air guide hopper is installed on the outer side of the gas pipe, and the air guide hopper is located inside the combustion head. Multiple annularly distributed openings are provided on the outer side wall of the gas pipe. Multiple fixing blocks are provided on the inner side wall of the gas pipe. A support rod is rotatably installed between adjacent fixing blocks. A connecting block is fixedly connected to the outer side of the support rod. A baffle for blocking the opening is connected to one end of the connecting block. A torsion spring is sleeved on the outer side of the support rod.

[0007] As a preferred embodiment of this utility model, the gas pipe has an L-shaped structure and extends to the outside of the burner body.

[0008] As a preferred embodiment of this utility model, a burner is installed at one end of the gas pipe, and an igniter is installed on the burner.

[0009] Compared with the prior art, the beneficial effects of this utility model are: the air guide hopper and the inlet allow air to enter the gas pipe and premix with the gas, and the stirring blades stir the gas and air to make the gas and air mix evenly, so as to ensure complete combustion of the gas and reduce the generation of pollutants.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 8 This utility model provides a technical solution: a gas burner for complete combustion, including a burner body 1 and a bellows 21 mounted on the burner body 1. A motor 2 is mounted on the outside of the burner body 1, and an impeller 9 is connected to the output end of the motor 2. The motor 2 drives the impeller 9 to rotate at high speed to generate centrifugal force, forming sufficient air pressure so that air enters from the bellows 21 and is delivered to the burner head 3. The burner body 1 has a burner head 3 at one end, and a gas pipe 6 is provided inside the burner head 3. A rotating rod 7 is rotatably mounted on the gas pipe 6. One end of the rotating rod 7 extends to the outside of the gas pipe 6, and a fan wheel 8 is mounted on one end of the rotating rod 7. The air delivered by the impeller 9 drives the fan wheel 8 to rotate, and the fan wheel 8 drives the rotating rod 7 to rotate. The rotating rod 7 causes the stirring blade 10 to rotate, and the stirring blade 10 stirs the gas and air to ensure that the gas and air are mixed evenly, thereby ensuring complete combustion and reducing the generation of pollutants. The other end of the rotating rod 7 is equipped with the stirring blade 10. An air guide hopper 12 is mounted on the outside of the gas pipe 6 to guide the air blown out by the impeller 9. Air is introduced into the gas pipe 6 through the inlet 11 to mix with the gas. The air guide duct 12 is located inside the burner head 3. The outer wall of the gas pipe 6 has multiple annularly distributed inlet 11. The inner wall of the gas pipe 6 has multiple fixing blocks 17. Support rods 13 are rotatably installed between adjacent fixing blocks 17. Connecting blocks 15 are fixedly connected to the outer side of the support rods 13. One end of the connecting block 15 is connected to a baffle 14 for blocking the inlet 11. The baffle 14 is used to block the gas in the gas pipe 6 and prevent the gas from flowing through. Air flows out through the opening 11. A torsion spring 16 is sleeved on the outside of the support rod 13. When air from the burner head 3 enters the gas pipe 6 through the opening 11, the baffle 14 rotates around the support rod 13 under the action of the air. The baffle 14 drives the connecting block 15 to rotate. The connecting block 15 causes the torsion spring 16 to be stressed through the extension part 20. When the motor 2 is turned off, air no longer enters the gas pipe 6 through the opening 11. The torsion spring 16 resets, causing the connecting block 15 to reset and rotate, thereby automatically resetting the baffle 14 and blocking the opening 11.

[0021] The support rod 13 has a retaining ring 18 on its outer side. The retaining ring 18 is used to limit the torsion spring 16 and prevent the torsion spring 16 from moving at will. The connecting block 15 has an extension 20 at the end away from the baffle 14. When the connecting block 15 rotates, the connecting block 15 will push one end of the torsion spring 16 to make the torsion spring 16 bear force. A slot 19 is opened on one side of the extension 20. One end of the torsion spring 16 is inserted into the slot 19, and the other end of the torsion spring 16 is pressed against the inner wall of the gas pipe 6.

[0022] Among them, the gas pipe 6 has an L-shaped structure and extends to the outside of the burner body 1.

[0023] One end of the gas pipe 6 is equipped with a burner 4, and an igniter 5 is installed on the burner 4. The igniter 5 is used to generate a high-voltage electric spark to ignite the mixture of gas and air and form an initial flame.

[0024] Specifically, during use, the motor 2 starts and rotates at high speed to generate centrifugal force, creating sufficient air pressure to allow air to enter from the bellows 21 and be delivered to the burner head 3. The air entering the burner head 3 then enters the gas pipe 6 through the inlet 11, while the gas also enters the gas pipe 6. When air enters the gas pipe 6 through the inlet 11, the baffle 14 rotates, allowing air to smoothly enter the gas pipe 6. However, when the gas attempts to move out of the gas pipe 6 through the inlet 11, the baffle 14 is blocked by the gas pipe 6 and cannot rotate. Therefore, the inlet 11 is blocked by the baffle 14, preventing the gas from moving out of the gas pipe 6 through the inlet 11. The air delivered by the impeller 9 will also drive the fan wheel 8 to rotate. The fan wheel 8 will cause the stirring blade 10 to rotate through the rotating rod 7. The stirring blade 10 will stir and mix the air and gas in the gas pipe 6, making the gas and air mixed evenly. The rotation of the stirring blade 10 can push the gas and air to the burner 4. The igniter 5 will generate a high-voltage electric spark to ignite the gas and air mixture, forming an initial flame, thus starting combustion.
