[0017] The intelligent combustion device for adaptive oxygen supply regulation provided in this embodiment of the utility model has at least one of the following technical effects:

[0018] The intelligent combustion device with adaptive oxygen supply regulation provided in this application uses a drive motor to rotate axial flow blades, drawing in air which is filtered by an intake screen before entering the intake mechanism. An ultrasonic oxygen sensor detects the oxygen concentration in real time and transmits the data to the electrical control box. The electrical control box adjusts the speed of the drive motor via a frequency converter according to a preset oxygen concentration threshold, thereby controlling the air intake. When the ultrasonic oxygen sensor detects insufficient oxygen, the electrical control box automatically increases the power of the drive motor and increases the speed of the axial flow blades, thereby increasing the air intake. Conversely, when there is excess oxygen, the power of the drive motor is reduced, decreasing the air intake. Through this closed-loop feedback control, real-time adaptive regulation of oxygen supply is achieved. Simultaneously, the electrical control box triggers an ignition needle to generate an electric spark, igniting the mixed gas ejected from the flame nozzle. During combustion, the regulating mechanism works continuously to ensure that the oxygen supply matches the combustion demand, resulting in more complete combustion, reduced energy waste, and improved safety.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0039] In one embodiment of this utility model, such as Figures 1-6 As shown, an intelligent combustion device that provides adaptive adjustment of oxygen supply includes an air intake 1, an adjustment mechanism 2, an air intake mechanism 3, a gas connector 4, an ignition mechanism 5, and a flame head 6. The air intake 1 is connected to the gas connector 4, the air intake 1 is electrically connected to the adjustment mechanism 2, and is connected to the air intake mechanism 3. The air intake mechanism 3 is respectively set on the air intake 1 and the flame head 6. The ignition mechanism 5 is set on the air intake mechanism 3 and is set on one side of the flame head 6.

[0040] The inhaler 1 includes an air intake shroud 11, a drive motor 12, and axial flow blades 13. One end of the air intake shroud 11 is connected to the air intake mechanism 3. The drive motor 12 is fixedly connected to the air intake shroud 11 and to the axial flow blades 13. The axial flow blades 13 generate airflow through the rotation of the drive motor 12, and the airflow flows to the air intake mechanism 3.

[0041] The electrical control box 21 supplies power to the drive motor 12 via the connecting cable 15. The drive motor 12 starts and drives the axial flow blades 13 to rotate at high speed. The rotation of the axial flow blades 13 generates centrifugal force, drawing air in through the intake screen 14 of the intake shroud 11. The intake screen 14 acts as a filter, preventing debris from entering and damaging the blades or affecting combustion. The axial airflow generated by the blade rotation pressurizes the air and delivers it to the first-stage intake cylinder 31, providing the necessary oxygen for combustion. Based on the oxygen concentration data fed back by the ultrasonic oxygen sensor 22, the electrical control box 21 adjusts the power of the drive motor 12 in real time, thereby changing the rotational speed of the axial flow blades 13 and achieving precise control of the intake volume.

[0042] The regulating mechanism 2 includes an electrical control box 21 and an ultrasonic oxygen sensor 22. The electrical control box 21 is located on one side of the inspirator 1, and the ultrasonic oxygen sensor 22 is fixedly connected to the air intake mechanism 3. The drive motor 12 and the ultrasonic oxygen sensor 22 are both electrically connected to the electrical control box 21.

[0043] The intelligent combustion device with adaptive oxygen supply regulation provided in this application uses a drive motor 12 to rotate axial flow blades 13. Air is drawn in, filtered by an intake screen 14, and then enters the intake mechanism 3. An ultrasonic oxygen sensor 22 detects the oxygen concentration in real time and transmits the data to an electrical control box 21. The electrical control box 21, based on a preset oxygen concentration threshold, adjusts the speed of the drive motor 12 via a frequency converter, thereby controlling the air intake. When the ultrasonic oxygen sensor 22 detects insufficient oxygen, the electrical control box 21 automatically increases the power of the drive motor 12, increasing the speed of the axial flow blades 13 and thus increasing the air intake. Conversely, when there is excess oxygen, the power of the drive motor 12 is reduced, decreasing the air intake. This closed-loop feedback control achieves real-time adaptive regulation of the oxygen supply. Simultaneously, the electrical control box 21 triggers an ignition needle 52 to generate an electric spark, igniting the mixed gas ejected from the flame nozzle 62. During combustion, the regulating mechanism 2 continuously operates to ensure that the oxygen supply matches the combustion demand, resulting in more complete combustion, reduced energy waste, and improved safety.

[0044] In another embodiment of this utility model, an air inlet 111 is provided at one end of the air intake shroud 11, and the air inlet 111 is connected to the air intake mechanism 3. When the vanes rotate, a negative pressure is formed inside the air intake shroud 11. After air is drawn in from the air intake mesh shroud 14 (if present), it is "pushed" to the air intake mechanism 3 through the air inlet 111.

[0045] In another embodiment of this utility model, the intake device 1 further includes an intake mesh cover 14 and a connecting line 15. The intake mesh cover 14 is connected to the inside of the intake hood 11 and is disposed on one side of the axial flow blade 13. The connecting line 15 is electrically connected to the drive motor 12 and the electrical control box 21 respectively. The intake mesh cover 14 is used to intercept dust, hair, particles and other impurities in the air, preventing them from entering the interior of the intake hood 11 and avoiding damage to the high-speed rotating axial flow blade 13 or blockage of the subsequent intake mechanism 3. The connecting line 15 stably delivers the electrical energy output from the electrical control box 21 to the drive motor 12, ensuring that the motor obtains the rated voltage and current, and maintaining the normal speed of the axial flow blade 13. According to the oxygen concentration data fed back by the ultrasonic oxygen sensor 22, the electrical control box 21 sends a speed regulation signal (such as PWM pulse width modulation) to the drive motor 12 through the connecting line 15 to adjust the speed of the axial flow blade 13 in real time, thereby achieving precise control of the intake volume.

[0046] In another embodiment of this utility model, the ultrasonic oxygen sensor 22 includes a sensor housing 221, an ultrasonic transducer 222, and a receiver 223. The ultrasonic transducer 222 is fixedly connected inside the sensor housing 221 and electrically connected to the receiver 223. The receiver 223 is fixedly connected to one side of the sensor housing 221 and electrically connected to the electrical control box 21. An airflow channel is provided inside the housing to allow air from the air intake mechanism 3 to flow smoothly through the sensor, ensuring measurement accuracy. The ultrasonic transducer 222 converts the electrical signal provided by the electrical control box 21 into ultrasonic pulses and emits them towards the receiver 223. Simultaneously, the ultrasonic transducer 222 uses high-precision piezoelectric ceramic material to ensure stable ultrasonic frequency (typically 40kHz~200kHz), avoiding measurement errors caused by environmental interference.

[0047] Receiver 223 is used for signal reception and conversion. Specifically, receiver 223 captures ultrasonic pulses and converts them back into electrical signals, measuring the time difference (TOF) between transmission and reception of the ultrasonic wave. Receiver 223 can preprocess the data, specifically amplifying and filtering the original signal to eliminate noise interference and improve measurement accuracy. Receiver 223 transmits the processed time difference data to control box 21 via connection line 15. Control box 21 calculates the oxygen concentration value using a temperature compensation model and adjusts the speed of drive motor 12 accordingly.

[0048] In another embodiment of this utility model, the air intake mechanism 3 includes a primary air intake cylinder 31, a secondary air intake cylinder 32, and a tertiary air intake cylinder 33. The primary air intake cylinder 31, the secondary air intake cylinder 32, and the tertiary air intake cylinder 33 are arranged and connected in sequence. The primary air intake cylinder 31 is fixedly connected to the air intake shroud 11 and is connected to the air intake port 111. The gas connector 4 is fixedly connected to the outside of the secondary air intake cylinder 32 and is connected to the secondary air intake cylinder 32.

[0049] The primary intake duct 31 is directly connected to the intake port 111 of the intake unit 1, receiving high-speed airflow and reducing its turbulence, allowing the airflow to smoothly enter the subsequent duct. The secondary intake duct 32 initially mixes with the airflow from the primary intake duct.

[0050] The diameter of the third-stage air intake 33 is further reduced, creating a Venturi effect, which increases the airflow velocity and the flame jet speed.

[0051] In another embodiment of this utility model, the ignition mechanism 5 includes an ignition fixing ring 51 and an ignition needle 52. The ignition fixing ring 51 is fixedly sleeved on the outside of the three-stage air intake cylinder 33, and the ignition needle 52 is fixedly installed on the ignition fixing ring 51, with one end set on one side of the flame head 6. The ignition needle 52 is electrically connected to the electrical control box 21.

[0052] The ignition retaining ring 51 is tightly fitted onto the outside of the three-stage air intake cylinder 33 via a ring structure, providing stable support for the ignition needle 52 and ensuring its precise alignment with the flame hole 62 of the burner head 6. The ignition retaining ring 51 is made of stainless steel or ceramic to resist the high-temperature radiation generated by combustion (up to 1000℃ or higher), preventing deformation or damage.

[0053] Triggered by the electrical control box 21, the ignition needle 52 generates a high-voltage pulse of 5000~15000V at its tip, breaking down the air gap to form an electric spark and igniting the gas mixture. The tip material of the ignition needle 52 is made of high-temperature resistant alloys such as tungsten and iridium (melting point > 3000℃) to ensure continuous operation in the flame without melting. When the equipment starts, the electrical control box 21 sends a high-voltage pulse signal to the ignition needle 52 to achieve automatic ignition. The distance between the end of the ignition needle 52 and the flame nozzle 62 is usually designed to be 3~5mm, ensuring that the electric spark can contact the gas mixture while preventing flame backburn and damage to the needle tip. The surface of the ignition needle 52 is coated with an insulating layer (such as a ceramic coating) to prevent carbon buildup or oil contamination from causing leakage and to ensure that the discharge energy is concentrated at the needle tip.

[0054] In another embodiment of the present invention, the flame head 6 includes a flame head body 61 and flame holes 62. One end of the flame head body 61 is fixedly connected to the three-stage air inlet cylinder 33. Multiple flame holes 62 are provided and are evenly arranged in a ring on the flame head body 61. The flame holes 62 are connected to the three-stage air inlet cylinder 33. The ignition needle 52 is provided on one side of the flame holes 62.

[0055] One end of the nozzle body 61 is rigidly connected to the three-stage air inlet cylinder 33 (such as by thread or flange connection) to ensure that the mixed gas is delivered to the flame hole 62 without leakage, while withstanding the high temperature and pressure generated by combustion (up to 0.5~2MPa).

[0056] The flame holes 62 are arranged in a uniform ring (usually 12 to 24 holes), so that the air and fuel gas mixture is ejected radially to form a circular flame surface that covers the heating area (such as boiler furnace, heating furnace).

[0057] The orifice diameter of the flame hole 62 is matched with the flow velocity. The orifice diameter of the flame hole 62 is usually 1~3mm. The number of holes and the diameter are adjusted according to the gas type (such as natural gas, propane) to ensure that the ejection velocity is greater than the flame propagation velocity (5~10m / s) and to avoid backfire.

[0058] The ignition needle 52 is located on one side of the flame hole 62 (3~5mm away), and the electric spark directly contacts the ejected air and gas mixture to ensure the success rate of ignition; after the flame is ignited, the flame is ejected from the flame hole 62.

[0059] In another embodiment of this utility model, a ball valve 7 is fixedly connected to the side of the primary intake cylinder 31, and the ball valve 7 is located on the side of the ultrasonic oxygen sensor 22. The ball valve 7 controls the airflow of the primary intake cylinder 31 by rotating the valve core (such as a spherical structure), with an opening range of 0% to 100%, thereby achieving precise adjustment of the intake volume (such as adjusting the air-fuel ratio to the optimal combustion state). The primary intake cylinder 31 serves as the first end of the intake mechanism 3. The air volume adjusted by the ball valve 7 is mixed with the fuel gas through the secondary and tertiary intake cylinders 33 and finally ejected through the flame nozzle 62. For example, increasing the opening of the ball valve 7 can increase the air volume, thereby increasing the air-fuel ratio and achieving more complete combustion.

[0060] The intelligent combustion device with adaptive oxygen supply regulation provided in this application uses a drive motor 12 to rotate axial flow blades 13. Air is drawn in, filtered by an intake screen 14, and then enters the intake mechanism 3. An ultrasonic oxygen sensor 22 detects the oxygen concentration in real time and transmits the data to an electrical control box 21. The electrical control box 21, based on a preset oxygen concentration threshold, adjusts the speed of the drive motor 12 via a frequency converter, thereby controlling the air intake. When the ultrasonic oxygen sensor 22 detects insufficient oxygen, the electrical control box 21 automatically increases the power of the drive motor 12, increasing the speed of the axial flow blades 13 and thus increasing the air intake. Conversely, when there is excess oxygen, the power of the drive motor 12 is reduced, decreasing the air intake. This closed-loop feedback control achieves real-time adaptive regulation of the oxygen supply. Simultaneously, the electrical control box 21 triggers an ignition needle 52 to generate an electric spark, igniting the mixed gas ejected from the flame nozzle 62. During combustion, the regulating mechanism 2 continuously operates to ensure that the oxygen supply matches the combustion demand, resulting in more complete combustion, reduced energy waste, and improved safety.

[0061] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
