Description

Technical Field

[0001] This invention relates to the field of choke control device technology, specifically a gasoline generator with an automatic choke control structure. Background Technology

[0002] In the field of internal combustion engine-driven power generation technology, gaseous fuels such as hydrogen and ammonia have become the core development direction of new energy internal combustion engines due to their clean and low-carbon characteristics. However, their characteristics of fast combustion speed, poor ignition stability, and high sensitivity to intake air cleanliness and air-fuel ratio pose serious challenges to the combustion optimization and efficient operation of general-purpose generators. Existing gasoline / gas dual-mode generators adapted to gaseous fuels have many technical bottlenecks.

[0003] First, automatic choke control is mostly based on a single temperature signal, failing to form a closed-loop linkage with intake pressure, air quality, and fuel type. This makes it impossible to accurately match the stringent air-fuel ratio requirements of gaseous fuels, resulting in difficulties with cold starts, large fluctuations during warm-up, and condensation in low-temperature intake air that can cause choke jamming, compromising combustion stability. Second, intake filtration and pressure regulation are independent, lacking an integrated design. Filter structures are mostly single-layer fixed forms, prone to clogging and requiring manual maintenance, with intake resistance continuously increasing over time. Pressure regulation relies heavily on throttle valve throttling, resulting in a delayed response and difficulty in handling fluctuations in intake parameters caused by sudden changes in air quality, failing to provide constant, controllable, and clean intake conditions for gaseous fuel internal combustion engines. Third, fuel premixing technology and combustion optimization technology are disconnected, resulting in poor premixing effects and an inability to dynamically adapt to operating conditions. Traditional premixing relies heavily on simple offset mixing, lacking a spiral turbulence enhancement structure, resulting in uneven mixing of air and atomizing medium. It also fails to dynamically adjust the gas-liquid mixing ratio based on air quality; poor air quality easily leads to combustion fluctuations and knocking, while excessive spraying reduces combustion efficiency in good air quality, making precise control of the homogeneous mixture impossible. Fourthly, the synergy between filter component cleaning and combustion optimization is insufficient, requiring manual intervention for maintenance. Existing cleaning mechanisms are mostly fixed-position cleaning, creating cleaning blind spots, and are not integrated with atomizing spray to form a wet cleaning system. Furthermore, the lack of an automatic cleaning trigger mechanism based on intake resistance feedback means that filter clogging easily leads to decreased intake efficiency, affecting the sustainability of high-efficiency combustion, increasing maintenance costs and downtime. Therefore, we propose a gasoline generator with an automatic choke control structure. Summary of the Invention

[0015] Compared with the prior art, the present invention provides a gasoline generator with an automatic choke control structure, which has the following advantages:

[0016] 1. By coordinating the intake channel, filter structure, spiral guide, pressure monitoring components and pressure regulation components, a high-precision intelligent intake control system adapted to gas fuel internal combustion engines is constructed, solving the technical defects of traditional generators such as insufficient intake cleanliness, unadjustable pressure and large gas supply fluctuations. The filtration and flow guiding structure simultaneously achieves intake air purification and spiral premixing. The pressure monitoring component provides real-time feedback on the intake air status. Combined with the telescopic adjustment and linkage transmission structure, the effective filtration area and intake air pressure and flow rate can be flexibly adjusted. The atomized water spray range and dosage can be adaptively adjusted according to the actual air quality, using atomized water to achieve wet dust interception, ensuring intake air cleanliness even in harsh air environments. At the same time, by precisely matching the spray volume with the effective filtration area, the intake resistance and flow rate are stabilized, avoiding sudden changes in intake parameters caused by differences in air quality. This provides constant, controllable, and clean intake conditions for gaseous fuel internal combustion engines, ensuring that the air-fuel ratio is maintained in the optimal stable range, precisely adapting to the stringent requirements of gaseous fuels for the air-fuel ratio. The drive and transmission components ensure smooth power transmission, and the coaxial positioning structure ensures that each component operates without deviation. Combined with the automatic adjustment of the choke, a stable and clean intake air supply is continuously provided for efficient combustion, significantly improving the overall operational stability of the engine.

[0017] 2. By integrating the pressure regulating component, the annular slide rail component, and the multi-degree-of-freedom cleaning structure, fully automatic deep cleaning of the filter components is achieved, overcoming the bottlenecks of traditional filter elements that are prone to clogging, require manual maintenance, and experience continuous decline in air intake efficiency. The telescopic scraping component can adhere to the inner wall to remove dirt, and together with the backflow airflow, it forms a dual cleaning effect; the annular slide rail and drive gear drive the cleaning module to move throughout the entire area, and the combined motion of the swing drive and the rotary cleaning structure achieves thorough cleaning without dead angles; the telescopic push rod adjusts the cleaning contact pressure, and the spray structure, together with the atomized medium, assists in wetting and removing dust. Multiple sets of bearings ensure smooth and unobstructed movement, maintaining unobstructed air intake for a long time without manual intervention, significantly extending the service life of the entire machine and reducing maintenance costs.

[0018] 3. Through the synergistic effect of rotating preheating components, airflow-driven blades, spiral guide structures, and gas-liquid spray structures, combustion optimization technology and fuel premixing technology are deeply integrated to comprehensively improve combustion efficiency under multiple fuel conditions. Airflow-driven blades rotate the preheating components, achieving uniform preheating of the intake air, improving the cold start characteristics of gaseous fuels, and preventing choke blockage caused by low-temperature condensation. The spiral guide enhances the uniformity of air-atomization medium mixing, forming a homogeneous gas-liquid mixture, achieving the homogeneous mixing requirements of fuel premixing technology. The gas-liquid mixing ratio is dynamically adjusted according to air quality; when air quality is poor, the gas-liquid mixing ratio is increased to suppress combustion fluctuations and prevent knocking and combustion disorder; when air quality is good, the gas-liquid mixing ratio is decreased to avoid excessive spraying and reduced combustion efficiency. This precisely adapts to the combustion needs of different environmental conditions throughout the process, ensuring the mixture always maintains optimal combustion conditions. Combined with closed-loop control of the choke and intake pressure, the mixture ratio remains constant and optimal, significantly improving combustion completeness and thermal efficiency, meeting the high-efficiency, stable, and low-emission operation requirements of gaseous fuel internal combustion engines.

Multiple sliding grooves are formed around the outer side of the sliding groove cylinder 424, and a cavity is formed on the inner side of the sliding groove cylinder 424.

[0042] Specifically, the servo cylinder 5 provides precise linear driving force, which, together with the C-shaped connecting rod 6, enables power steering transmission; the cavity rod 421 serves as the core mounting carrier of the pressure control component 42, and its internal cavity can reserve space for wiring and air passages; the annular bracket 422 enables the cavity rod 421 to be coaxially fixed with the assembly cylinder 423 and the sliding groove cylinder 424, ensuring transmission accuracy; the assembly cylinder 423 provides a sliding guide channel for the stop block 4212; the outer sliding groove of the sliding groove cylinder 424 provides a directional sliding trajectory for the guide rod 428, and the inner cavity is used to accommodate the first electric push rod 426, achieving structural integration; the baffle 425 provides telescopic limit support for the stop block 4212, and at the same time, together with the assembly cylinder 423, forms an airflow backflow space to enhance the cleaning effect of the filter cartridge 412.

After the multiple stop blocks 4212 are in contact, they form a circle.

[0046] Specifically, the inner clamping plate 429 receives the thrust of the guide rod 428 and transmits it to the second connecting rod 4210; the second connecting rod 4210 converts linear motion into radial extension and retraction of the stop block 4212 through angle change (oblique → vertical); the outer clamping plate 4211 disperses the force of the second connecting rod 4210 to ensure that the stop block 4212 is subjected to uniform force; multiple stop blocks 4212 fit together to form a circular structure, which can not only scrape off the dirt attached to the inner wall of the filter cartridge 412, but also adjust the space of the filter cartridge 412 by telescopic position adjustment to achieve precise control of intake pressure and flow, adapting to the sensitive air-fuel ratio requirements of gas fuel internal combustion engines.

[0047] In this embodiment, the other end of the baffle 425 is fixedly connected to an annular toothed track 711. The cross-section of the annular toothed track 711 is T-shaped. An installation box 712 is provided on the outer side of the annular toothed track 711. A first motor 713 is installed on one side of the installation box 712.

Two sets of mutually symmetrical rollers are provided on the outer side of the installation box 712. The installation box 712 is slidably connected to the outer side of the annular toothed track 711 through the rollers.

[0048] Specifically, the annular toothed track 711 provides an annular sliding trajectory for the mounting box 712, and the T-shaped cross-section design prevents the mounting box 712 from falling off; the mounting box 712 integrates core components such as the solenoid valve spray head 716 and the cleaning head 7212, realizing the modular layout of the maintenance mechanism 7; the first motor 713 provides rotational power, and drives the mounting box 712 to move in annularly through the meshing transmission of the first gear 714 and the annular toothed track 711; the rollers reduce the sliding friction between the mounting box 712 and the annular toothed track 711, ensuring smooth movement and realizing cleaning and atomized water spray coverage of the entire circumference of the filter cartridge 412.

[0049] In this embodiment, a liquid storage tank 715 is installed on the inner side of the chute cylinder 424. Deionized atomized water is provided on the inner side of the liquid storage tank 715. A solenoid valve spray head 716 is provided on the output shaft of the liquid storage tank 715 through a hose.

The outer side of the lower fixed bearing 726 is fixedly connected to the mounting box 712 through a bracket. At least four limiting slide rods 727 are slidably connected to the inner side of the sliding bearing 725.

[0052] Specifically, the second motor 721 provides oscillating power, which drives the second toothed ring 723 to oscillate back and forth through the second gear 722, thereby driving the cleaning head 7212 to achieve lateral cleaning; the third motor 724 provides rotational power, driving the slide bearing 725 to rotate; the lower fixed bearing 726 ensures the stable rotation of the slide bearing 725 and prevents it from shifting; the slide bearing 725 drives the limiting slide rod 727 to rotate synchronously, while allowing the limiting slide rod 727 to slide axially, adapting to the extension and retraction of the cleaning head 7212, and realizing flexible adjustment of cleaning pressure.

[0053] In this embodiment, the same end of multiple limiting slide rods 727 is rotatably connected to a fixed rod 728 via a rotating shaft. The outer sides of the multiple fixed rods 728 are jointly fixedly connected to an assembly bearing 729. The outer side of the assembly bearing 729 is rotatably connected to an upper fixed bearing 7210. The outer side of the upper fixed bearing 7210 is fixedly connected to a second toothed ring 723 via a bracket. A second electric push rod 7211 is provided on the inner axis of the assembly bearing 729. The output shaft of the second electric push rod 7211 is fixedly connected to a cleaning head 7212.

[0054] Specifically, the fixed rod 728 connects the limiting slide rod 727 and the assembly bearing 729, transmitting rotational power while adapting to angle changes; the assembly bearing 729 decouples the movement of the second electric push rod 7211 from the fixed rod 728, ensuring that the cleaning head 7212 can both rotate and swing; the upper fixed bearing 7210 connects the assembly bearing 729 and the second toothed ring 723, realizing the transmission of swinging power; the second electric push rod 7211 drives the cleaning head 7212 to extend and retract, adjusting its contact pressure with the inner wall of the filter cartridge 412; the cleaning head 7212 achieves deep cleaning of the inner wall of the filter cartridge 412 through the combined motion of rotation and swing, ensuring unobstructed air intake and providing stable air intake conditions for efficient combustion.

[0055] Working principle: When in use, according to the fuel type and the engine's cold and hot start requirements, the choke body 3 is opened. The outside air enters the choke body 3 after being purified, mixed, and preheated / gas-liquid premixed by the control mechanism 4. The choke body precisely adjusts the concentration of the mixture and finally introduces it into the cylinder of the generator body 1 to participate in combustion. The whole process realizes closed-loop control of fuel premixing and efficient combustion.

[0056] The airflow first enters the filter cartridge 412, where it undergoes initial dust removal and purification through the filter holes on the outside of the cartridge 412. This prevents impurities from entering the cylinder, aggravating wear, or affecting the combustion stability of the gaseous fuel. The purified airflow then passes through the filter holes and enters the air inlet duct 411, where it forms a spiral airflow under the guidance of the spiral blades 413. This spiral structure enhances the mixing uniformity of the airflow with the subsequent atomizing medium and increases the intake turbulence, laying the foundation for efficient combustion. As the airflow flows, its kinetic energy drives the blades 416 to rotate, which in turn drives the heating wire 415 and the cross rod 414 to rotate synchronously around the axis of the filter cartridge 412. The rotating heating wire 415 can uniformly preheat the spiral airflow, solving the problem of difficult atomization and ignition during cold starts of the gaseous fuel and preventing condensation in the low-temperature intake air from causing the choke to jam. The initial combustion conditions are optimized through intake temperature control. The pressure sensor inside the filter cartridge 412 monitors the intake resistance in real time, providing signal support for subsequent cleaning, maintenance, and pressure regulation.

[0057] Before entering the choke body 3 and generator body 1, the air undergoes multi-stage filtration to ensure intake air cleanliness, which is a key prerequisite for the stable operation of the gas fuel internal combustion engine. When the pressure sensor detects abnormal intake resistance and determines that the filter cartridge 412 is clogged, the control mechanism 4 activates the pressure control component 42 to simultaneously clean the filter element and compensate for the intake pressure, ensuring a stable intake volume required for efficient combustion. The specific actions are as follows: First, the first electric push rod 426 is activated, and its output shaft extends and passes through the annular bracket 422, driving the limiting plate 427 and multiple guide rods 428 to slide synchronously along the slide groove of the sliding cylinder 424 until the limiting plate 427 is in contact with the inner wall of the assembly cylinder 423. During this process, one end of multiple stops 4212 first abuts against the baffle 425 for limitation, and the first electric push rod 426 continuously outputs thrust. Under the reverse support of the baffle 425, the guide rods 428 push the inner clamping plate 429 to move. The two sets of second connecting rods 4210 gradually change from an inclined state to a vertical state. Through the connecting rod transmission, the outer clamping plate 4211 and the stop block 4212 are driven to slide out of the assembly cylinder 423 and fit tightly against the inner wall of the filter cylinder 412. Then, the servo cylinder 5 is activated, and its output shaft pulls the cavity rod 421 towards the input end of the filter cylinder 412 through the C-shaped connecting rod 6. This drives the multiple stop blocks 4212 that are attached to the inner wall of the filter cylinder 412 to scrape off the particulate dirt attached to the inside of the filter holes and restore the flow capacity of the filter holes.

[0058] After cleaning, the output shaft of the first electric actuator 426 retracts, driving the stop block 4212 to retract into the assembly cylinder 423 and reset. The output shaft of the servo cylinder 5 retracts synchronously, pulling the assembly cylinder 423 and the baffle 425 into the filter cylinder 412. During this process, the movement of the assembly cylinder 423 compresses the airflow inside the filter cylinder 412, causing some of the airflow to flow back along the gap between the filter cylinder 412 and the assembly cylinder 423, impacting the inner wall of the filter cylinder 412 in the opposite direction, thoroughly removing the loose dirt after scraping, ensuring that the air intake channel is clean and unobstructed, and providing stable air intake conditions for efficient combustion.

[0059] When the ambient air quality is poor, such as when the dust concentration is high, the extension position of the baffle 4212 is adjusted by the pressure control component 42 to divide the internal space of the filter cartridge 412 into two parts, so that the airflow is filtered only through the filter holes that are not blocked near the inlet side. By reducing the effective filtration area, the intake resistance is increased, thereby precisely controlling the intake pressure and flow rate, adapting to the sensitive requirements of the gas fuel internal combustion engine for air-fuel ratio, and avoiding incomplete combustion due to excessive or insufficient intake air.

[0060] During the operation of the control mechanism 4, the maintenance mechanism 7 can be activated simultaneously to achieve deep cleaning of the filter cartridge 412 and gas-liquid premixing, further optimizing the combustion effect: First, the second motor 721 is activated, and its output shaft drives the second gear 722 to rotate. Through gear meshing, the second toothed ring 723 swings back and forth with a maximum rotation range of 180° laterally. Then, the second electric push rod 7211 is activated, and its output shaft pushes the cleaning head 7212 to adhere to the inner wall of the filter cartridge 412. At the same time, the solenoid valve spray head 716 is opened to atomize and spray out the deionized water in the storage tank 715. On the one hand, the mounting box 712 and the inner wall of the filter cartridge 412 are moistened and cleaned. On the other hand, the atomized water and the filtered clean airflow are fully mixed to form a gas-liquid homogeneous mixture. The mixture of gas and fuel enters the cylinder of the generator body 1, which can reduce the combustion temperature in the cylinder and effectively suppress the knocking phenomenon caused by the rapid combustion of hydrogen fuel. At the same time, it can prevent carbon deposits from being sintered on the choke body 3 and the intake manifold, thus extending the service life of the gas fuel internal combustion engine. Then, the third motor 724 is started. Its output shaft drives the sliding bearing 725 to rotate. The lower fixed bearing 726 ensures the rotational stability. The sliding bearing 725 drives multiple limit sliding rods 727 to rotate synchronously. Through the fixed rod 728 and the assembly bearing 729, the cleaning head 7212 is driven to rotate and brush the inner wall of the filter cylinder 412. Combined with the second toothed ring 723 driving the upper fixed bearing 7210 to reciprocate, deep cleaning of half a circumference of the filter cylinder 412 is achieved.

[0061] After completing half a cycle of cleaning, the first motor 713 is started, and its output shaft drives the first gear 714 to rotate. Through the meshing transmission between the gear and the annular toothed track 711, the mounting box 712 is driven to move back and forth along the annular toothed track 711 with a maximum longitudinal rotation range of 180°. Simultaneously, the solenoid valve spray head 716 and the cleaning head 7212 complete the cleaning and atomized water spraying of the remaining half cycle of the filter cartridge 412. When the airflow passes through the air inlet duct 411, it is further spirally mixed with the atomized water under the guidance of the spiral blade 413 to form a homogeneous gas-liquid mixture before entering the wind choke body 3 to ensure complete combustion. Meanwhile, the maintenance mechanism 7 has the ability to adapt to different operating conditions: when the filter cartridge 412 is separated by the baffle 4212, if the proportion of effectively filtered air is small and the current air quality is judged to be poor, the solenoid valve spray head 716 will automatically expand the spraying range and increase the spraying amount, trap dust and impurities with more atomized water, and increase the gas-liquid mixing ratio to suppress combustion fluctuations; if the proportion of effectively filtered air is large and the air quality is judged to be good, the solenoid valve spray head 716 will reduce the spraying range and reduce the spraying amount, accurately adapting to the combustion needs under different environmental conditions, and achieving a dynamic balance between combustion optimization and efficient combustion throughout the process.
