Description

Technical Field

[0001] This utility model relates to the field of combustion device technology, and more specifically, to an air-stage combustion device. Background Technology

[0002] Outdoor gas heaters primarily generate heat by burning gas and then dissipate that heat into the surrounding environment in a specific way to achieve the purpose of heating. As people's awareness of energy efficiency and environmental protection continues to increase, the limitations of traditional combustion devices are becoming increasingly apparent.

[0003] A search revealed Chinese patent CN215583917U, which discloses a multifunctional outdoor heater. This invention addresses the problems of existing outdoor heaters, such as reduced heat conduction due to their non-enclosed design, minimal heating of the torso (from ankle to toe) instead of the head (vertically from top to bottom), and the cumbersome need for constant monitoring to prevent fires. By incorporating a heating lamp and heater, and combining electricity and gas, this invention improves outdoor heating, ensuring warmth reaches both the feet and body. Furthermore, the heater includes a fire extinguisher with multiple activation methods to prevent accidents from spreading due to the difficulty of immediate response.

[0004] Gas combustion devices often employ a relatively simple combustion method, resulting in insufficient mixing of gas and air. This leads to significant energy loss during combustion. Because air and gas cannot be mixed evenly, some gas cannot come into contact with enough oxygen in time, preventing the combustion reaction from proceeding completely. This not only wastes gas but also prevents the heat generated from combustion from reaching the ideal level, making it difficult to meet people's needs for efficient heating. Furthermore, the uneven distribution of gas concentration during combustion can easily cause combustion fluctuations, resulting in poor flame stability and the possibility of flame extinguishing or unstable combustion. Utility Model Content

[0005] In order to overcome the problems and defects in the prior art, this utility model provides an air staged combustion device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an air-stage combustion device, comprising a device base plate, a gas cylinder fixedly installed on the top of the device base plate, a gas pipe fixedly connected to the top of the gas cylinder, a burner head fixedly installed on the top of the gas pipe, and a vortex combustion mechanism provided on the top of the burner head;

[0007] The vortex combustion mechanism includes a fixed sleeve fixed to the top of the burner head. The fixed sleeve has an inner cavity. An exhaust fan is installed on one side of the fixed sleeve. An air inlet pipe is fixedly connected between the fixed sleeve and the exhaust fan. Multiple inclined air outlets are opened through the inner wall surface of the fixed sleeve. A first igniter is fixedly installed at the bottom of the inner wall of the fixed sleeve. A bearing is sleeved and installed on the outside of the first igniter. A connecting branch pipe is fixedly connected to the outside of the bearing. A second igniter is fixedly installed at one end of the connecting branch pipe. A secondary combustion mechanism is provided at the top of the fixed sleeve.

[0008] Preferably, the secondary combustion mechanism includes an ignition tube, which is fixedly installed on the top of the fixed sleeve, and the outer surface of the ignition tube is provided with a plurality of air circulation holes evenly distributed.

[0009] Preferably, the ignition tube has an internal air chamber, and an inclined air outlet pipe is fixedly installed on the inner wall of the air chamber.

[0010] Preferably, a fixing block is fixedly connected to the top of the ignition tube, an air pump is fixedly installed on the top of the fixing block, and a connecting pipe is fixedly connected between the air pump and the air chamber.

[0011] Preferably, a fixing rod is fixedly installed inside the ignition tube, and a rotating fan blade is fixedly installed at the bottom of the fixing rod.

[0012] Preferably, a reflective umbrella cover is fixedly sleeved on the outside of the fixing block.

[0013] Preferably, the bottom of the first igniter is fixedly connected to the burner head, the number of the second igniters is set to multiple, and a gas regulating valve is fixedly installed on the front side of the burner head.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] By setting up a vortex combustion mechanism and a secondary combustion mechanism, the exhaust fan introduces air and forms a rotating vortex airflow within the fixed sleeve, enabling good mixing of gas and air in the initial combustion stage. Multiple secondary igniters further ensure complete ignition and combustion of the gas, greatly improving the initial combustion efficiency and reducing energy loss due to incomplete combustion. The air pump supplies air, and the inclined exhaust pipe and air flow hole introduce air to fully mix with the incompletely burned gas. The stirring action of the rotating fan blades promotes secondary combustion, further improving the overall combustion efficiency and enabling the fuel to release more heat, achieving efficient energy utilization. Compared with traditional combustion devices, it can generate more heat energy with the same gas consumption, reducing energy costs.

[0016] By rotating the fan blades to stir and disperse the mixed gas inside the ignition tube, the uniformity of the mixed gas during secondary combustion is maintained, further enhancing combustion stability and avoiding combustion fluctuations caused by uneven local gas concentration. This provides users with a continuous and stable heat output, improving the user experience. The efficient combustion process allows the fuel to burn more completely, reducing the generation of harmful gases such as carbon monoxide and hydrocarbons from incomplete combustion. While meeting heating needs, it also reduces pollution to the surrounding environment, meeting environmental protection requirements. Attached Figure Description

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.

[0025] As attached Figure 1-6An air-stage combustion device is shown, including a device base plate 1, a gas tank 2 is fixedly installed on the top of the device base plate 1, a gas pipe 3 is fixedly connected to the top of the gas tank 2, a burner head 4 is fixedly installed on the top of the gas pipe 3, and a vortex combustion mechanism is provided on the top of the burner head 4.

[0026] The vortex combustion mechanism includes a fixed sleeve 5, which is fixed to the top of the burner head 4. The fixed sleeve 5 has an inner cavity 6. An exhaust fan 7 is installed on one side of the fixed sleeve 5. An air inlet pipe 8 is fixedly connected between the fixed sleeve 5 and the exhaust fan 7. Multiple inclined air outlets 9 are opened through the inner wall surface of the fixed sleeve 5. A first igniter 10 is fixedly installed at the bottom of the inner wall of the fixed sleeve 5. A bearing 11 is sleeved on the outside of the first igniter 10. A connecting branch pipe 12 is fixedly connected to the outside of the bearing 11. A second igniter 13 is fixedly installed at one end of the connecting branch pipe 12. A secondary combustion mechanism is provided at the top of the fixed sleeve 5.

[0027] As attached Figure 1-5 As shown, the secondary combustion mechanism includes an ignition tube 14, which is fixedly installed on the top of the fixed sleeve 5. Multiple air flow holes 15 are evenly opened on the outer surface of the ignition tube 14. An air chamber 16 is opened inside the ignition tube 14. An inclined air outlet pipe 17 is fixedly installed on the inner wall of the air chamber 16. A fixed block 18 is fixedly connected to the top of the ignition tube 14. An air pump 20 is fixedly installed on the top of the fixed block 18. A connecting pipe 19 is fixedly connected between the air pump 20 and the air chamber 16. A fixed rod 21 is fixedly installed inside the ignition tube 14. A rotating fan blade 22 is fixedly installed at the bottom of the fixed rod 21 to further improve the mixing effect of gas and air and effectively avoid the phenomenon of incomplete combustion of air.

[0028] As attached Figure 1 , 2 As shown, a reflective umbrella cover 23 is fixedly fitted on the outside of the fixing block 18 to improve the heating effect and prevent excessive heat dissipation.

[0029] As attached Figure 1 , 2 As shown in Figures 4 and 6, the bottom of the first igniter 10 is fixedly connected to the burner head 4, and the number of second igniters 13 is set to multiple to improve the combustion effect. A gas regulating valve 24 is fixedly installed on the front side of the burner head 4 to facilitate the adjustment of the gas volume.

[0030] The working principle of this utility model is as follows: Gas is stored in a gas tank 2 at the top of the device's base plate 1. Gas is transported from the top of the gas tank 2 to the burner head 4 via a gas pipe 3. The gas flow rate can be precisely controlled by the gas regulating valve 24 on the front side of the burner head 4, thereby adjusting the combustion intensity according to actual needs. The exhaust fan 7 draws outside air into the inner cavity 6 of the fixed sleeve 5 through the air inlet pipe 8. The air forms a certain pressure in the inner cavity 6. Because multiple inclined air outlets 9 are perforated on the inner wall surface of the fixed sleeve 5, air is ejected at high speed from these inclined air outlets 9. A rotating vortex airflow is formed inside the fixed sleeve 5. The first igniter 10 at the bottom of the inner wall of the fixed sleeve 5 generates an electric spark, igniting the gas ejected from the burner head 4 and initially mixed with the rotating air, thus forming initial combustion. At the same time, the bearing 11 and the connecting branch pipe 12 installed on the outside of the first igniter 10 provide support and connection. Multiple second igniters 13 at one end of the connecting branch pipe 12 further ensure that the gas is fully ignited and burned in the rotating vortex, making the combustion more stable and uniform, improving the efficiency of initial combustion, and reducing the generation of incomplete combustion products.

[0031] Air pump 20 supplies air to the air chamber 16 inside the ignition tube 14 through connecting pipe 19. The inclined exhaust pipe 17 on the inner wall of the air chamber 16 ejects the gas at a specific angle, further mixing it with the incompletely burned gas rising from the vortex combustion mechanism into the ignition tube 14. Multiple air vents 15 evenly distributed on the outer surface of the ignition tube 14 also introduce outside air, increasing the oxygen content in the mixture and providing sufficient oxidant for secondary combustion. Inside the ignition tube 14, the rotating fan blades 22 at the bottom of the fixed rod 21 rotate under the action of airflow, stirring and dispersing the mixture. Its distribution is more uniform, which is conducive to the combustion reaction. At this time, if there are unburned gas components, they will be ignited again under the stirring of the rotating fan blades 22 and the full mixing of air, realizing secondary combustion, further improving combustion efficiency, making the fuel burn more completely, releasing more heat, and reducing harmful gas emissions. The reflective umbrella cover 23 fixedly sleeved on the outside of the fixed block 18 can reflect and radiate the heat generated by combustion to the surroundings, improving the heat utilization rate, so that the combustion device can more effectively provide warmth to the surrounding space in the outdoor environment and enhance the heating effect.

[0032] In conclusion, the above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
