[0003] Existing technical solutions rely solely on the negative pressure generated by the airflow velocity at the throat for initial atomization. The diameter of fuel particles is mostly between 80-150μm, making it difficult to form fine and uniform fuel mist. This results in insufficient mixing of fuel and air, making it difficult to meet the requirements for efficient combustion.

[0004] To address the above problems, this utility model provides a carburetor with high-efficiency atomization. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing carburetors have insufficient atomization fineness, making it difficult to meet the requirements of high-efficiency combustion, and to propose a carburetor with high-efficiency atomization.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a high-efficiency atomizing carburetor, comprising a carburetor body, an atomizing mechanism, and a fuel supply mechanism, wherein the atomizing mechanism is fixedly connected to the interior of the carburetor body, and the fuel supply mechanism is threadedly connected to the outer surface of the carburetor body, and the atomizing mechanism includes sealing gaskets threadedly connected to both ends of the carburetor body.

[0007] The atomizing mechanism includes a high-efficiency atomizing component and an air intake component. The high-efficiency atomizing component includes a pre-atomizing conical spray head and a spiral guide plate. The air intake component includes an air filter.

[0008] The pre-atomizing conical spray head is fixedly connected to one side of the inner wall of the carburetor body. The outer surface of the pre-atomizing conical spray head is provided with a plurality of pre-atomizing holes at equal intervals. The atomizing mechanism also includes a fixed circular plate symmetrically fixedly connected to the inner wall of the carburetor body. The fixed circular plate divides the inner wall of the carburetor body into a preliminary atomizing chamber and an air mixing atomizing chamber. The pre-atomizing conical spray head is fixedly connected to the inside of the preliminary atomizing chamber, and the spiral guide plate is fixedly connected to the inside of the air mixing atomizing chamber.

[0009] Furthermore, the fixed circular plates are symmetrically arranged on the inner wall of the carburetor body, and a rotating bearing is fitted on the outer surface of the fixed circular plates. The two ends of the spiral guide plate are rotatably connected to the interior of the symmetrically arranged fixed circular plates through the rotating bearing.

[0010] Furthermore, the air intake assembly is fixedly connected to the outer surface of the top of the carburetor body, the interior of the air intake assembly is connected through the interior of the carburetor body, the air intake assembly is fixedly connected to the top of the air mixing and atomizing chamber, and the air intake assembly includes an air intake pipe fixedly connected to the top of the carburetor body.

[0011] Furthermore, the air filter is fixedly connected to the inside of the air intake pipe, an air flow sensor is fixedly connected to one end of the air intake pipe, an air connecting pipe is fixedly connected to the other side of the air intake pipe, and a preliminary air filter is fixedly connected to the inner wall of the air connecting pipe.

[0012] Furthermore, the atomizing mechanism also includes connecting bolts threaded to both sides of the carburetor body, the sealing gaskets are threaded to both sides of the carburetor body via the connecting bolts, one side of the carburetor body is threaded to the intake manifold via the connecting bolts, and the fuel supply mechanism is threaded to the other side of the carburetor body via the connecting bolts.

[0014] Furthermore, a suction pipe is fixedly connected to one side of the outer surface of the fuel pump, and an oil pipe is fixedly connected to the other side of the outer surface of the fuel pump. One end of the oil pipe is fixedly connected to the inside of the fuel filter, and the fuel filter is precisely aligned with the outer surface of the pre-atomizing cone spray head.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, by setting up a pre-atomizing conical spray head, a spiral guide plate, and an air flow sensor, the staged atomization of fuel and dynamic matching of air-fuel ratio are achieved. The multiple fine pre-atomizing holes of the pre-atomizing conical spray head can initially break the fuel into oil mist particles, improving the atomization precision. The spiral guide plate rotates under the push of airflow, so that the oil mist and air form a spiral mixing flow, which can increase the contact area and improve the mixing uniformity. The air flow sensor provides real-time feedback of intake air data, controls the fuel pump supply, and ensures that the air-fuel ratio is stable within the ideal range at different speeds.

The dual filtration structure of the fuel filter and air filter can comprehensively intercept impurities in the fuel and air, avoiding clogging of the pre-atomization holes. The connection method adopts a combination of quick-connect fittings and threaded connections, which makes disassembly and replacement convenient and reduces maintenance difficulty and cost.

[0019] Please see Figure 1-6 This utility model provides a technical solution: a high-efficiency atomizing carburetor, including a carburetor body 1, an atomizing mechanism 2 and a fuel supply mechanism 3. The atomizing mechanism 2 is fixedly connected to the inside of the carburetor body 1, and the fuel supply mechanism 3 is threadedly connected to the outer surface of the carburetor body 1. The atomizing mechanism 2 includes sealing gaskets 21 threadedly connected to both ends of the carburetor body 1.

[0020] The specific setup and function of its atomizing mechanism 2 and fuel supply mechanism 3 will be explained below.

[0021] In this embodiment: the atomizing mechanism 2 includes a high-efficiency atomizing component 22 and an air intake component 23. The high-efficiency atomizing component 22 includes a pre-atomizing cone spray head 221 and a spiral guide plate 222. The air intake component 23 includes an air filter 231.

[0022] The pre-atomizing conical spray head 221 is fixedly connected to one side of the inner wall of the carburetor body 1. The outer surface of the pre-atomizing conical spray head 221 is provided with a plurality of pre-atomizing holes 223 at equal intervals. The atomizing mechanism 2 also includes a fixed circular plate 224 symmetrically fixedly connected to the inner wall of the carburetor body 1. The fixed circular plate 224 divides the inner wall of the carburetor body 1 into a preliminary atomizing chamber 225 and an air mixing atomizing chamber 226. The pre-atomizing conical spray head 221 is fixedly connected to the inside of the preliminary atomizing chamber 225, and the spiral guide plate 222 is fixedly connected to the inside of the air mixing atomizing chamber 226.

[0023] The effects achieved by the above components are as follows: the coordinated design of the high-efficiency atomizing component 22 and the air intake component 23, the pre-atomizing cone spray head 221 disperses the fuel from the columnar flow into preliminary mist particles through multiple pre-atomizing holes 223 evenly distributed on the outer surface, laying the foundation for subsequent deep mixing, the spiral guide plate 222 can guide the airflow and fuel mist to form a spiral motion, greatly increasing the contact area and mixing time between the two, the air filter 231 can filter out dust and impurities in the intake air, and prevent pollutants from adhering to the surface of the atomizing component and affecting the atomization efficiency, the symmetrically arranged fixed circular plate 224 precisely divides the interior of the carburetor body 1 into the preliminary atomization chamber 225 and the air mixing atomization chamber 226, so that the fuel atomization and fuel-air mixing are carried out in an orderly manner in an independent and continuous space, effectively avoiding mutual interference between the two processes, ensuring that the atomized fuel mist can be fully integrated with the clean air in the air mixing atomization chamber 226, and significantly improving the uniformity of the combustible mixture.

[0024] Specifically, the fixed circular plate 224 is symmetrically arranged on the inner wall of the carburetor body 1, and the outer surface of the fixed circular plate 224 is fitted with a rotating bearing 227. The two ends of the spiral guide plate 222 are rotatably connected to the interior of the symmetrically arranged fixed circular plate 224 through the rotating bearing 227.

[0025] The effects achieved by the above components are as follows: the symmetrical arrangement of the fixed circular plate 224 provides stable installation support for the spiral guide plate 222. The rotating bearing 227 embedded on its outer surface transforms the fixed connection of the spiral guide plate 222 into a flexible rotating connection. When air enters the air mixing atomization chamber 226 from the air intake assembly 23, the thrust of the airflow can drive the spiral guide plate 222 to rotate freely around the bearing, forming a dynamic stirring effect. This rotational motion can not only further shear and refine the oil mist particles after initial atomization, but also allow the oil mist and air to fully intertwine under the dual action of centrifugal force and airflow thrust, improving the uniformity of oil-air mixing. At the same time, the low friction characteristics of the rotating bearing 227 ensure that the guide plate operates smoothly for a long time without the risk of jamming.

[0026] Specifically, the intake assembly 23 is fixedly connected to the outer surface of the top of the carburetor body 1, the interior of the intake assembly 23 is connected through the interior of the carburetor body 1, the intake assembly 23 is fixedly connected to the top of the air mixing atomization chamber 226, and the intake assembly 23 includes an intake pipe 232 fixedly connected to the top of the carburetor body 1.

[0027] The effects achieved by the above components are as follows: the intake assembly 23 is fixed to the top of the carburetor body 1 and is connected to the air mixing atomization chamber 226, which can accurately introduce external air into the mixing area and provide sufficient air source for fuel-air mixing. The intake pipe 232, as the main intake channel, has an optimized pipe diameter and length to reduce air flow resistance and ensure smooth and stable intake. At the same time, the fixed connection and through structure between the intake pipe 232 and the carburetor body 1 avoids air leakage during the intake process, ensures the stability of air flow, and provides the basis for the precise control of the air-fuel ratio.

[0028] Specifically, the air filter 231 is fixedly connected to the inside of the air intake pipe 232. An air flow sensor 233 is fixedly connected to one end of the air intake pipe 232, and an air connecting pipe 234 is fixedly connected to the other side of the air intake pipe 232. An air pre-filter 235 is fixedly connected to the inner wall of the air connecting pipe 234.

[0029] The effects achieved by the above components are as follows: the primary air filter 235 first pre-filters the air entering the intake pipe 232, intercepting larger particulate impurities and reducing the filtration load of the air filter 231. The air filter 231 then deeply purifies the air through a multi-layer filtration structure, ensuring the cleanliness of the air entering the mixing chamber and effectively protecting precision components such as the pre-atomizing hole 223 and the spiral guide plate 222 from wear or blockage by impurities. The air flow sensor 233 can detect the air flow through the intake pipe 232 in real time and accurately, and transmit the data to the control unit to provide a basis for adjusting the fuel supply, realize dynamic matching of the air-fuel ratio, and avoid the problem of overly rich or lean mixture caused by fluctuations in the intake volume.

[0030] Specifically, the atomizing mechanism 2 also includes connecting bolts 24 threaded to both sides of the carburetor body 1, sealing gaskets 21 threaded to both sides of the carburetor body 1 via connecting bolts 24, an intake manifold 25 threaded to one side of the carburetor body 1 via connecting bolts 24, and a fuel supply mechanism 3 threaded to the other side of the carburetor body 1 via connecting bolts 24.

[0031] The effects achieved by the above components are as follows: the connecting bolt 24 adopts a threaded connection, which realizes the detachable fixation of the atomizing mechanism 2 to the carburetor body 1, the intake manifold 25, and the fuel supply mechanism 3. The connection strength is high and the disassembly and assembly are convenient, which facilitates the maintenance, repair and replacement of components. Under the tightening action of the connecting bolt 24, the sealing gasket 21 fits tightly into the gap of each connection part, effectively preventing the leakage of the oil-air mixture and the entry of external dust and moisture into the carburetor, ensuring the sealing performance and working stability of the carburetor. The intake manifold 25, as the output channel of the air-fuel mixture, can stably deliver a uniform combustible mixture to the internal combustion engine cylinder, ensuring that the combustion process proceeds in an orderly manner. The reliable connection between the fuel supply mechanism 3 and the carburetor body 1 provides a continuous and stable fuel source for the atomizing components.

[0032] Specifically, the fuel supply mechanism 3 includes a fixing frame 31 that is threadedly connected to the outer surface of the carburetor body 1 by connecting bolts 24. A fuel filter 32 is fixedly connected inside the fixing frame 31, and a fuel pump 33 is fixedly connected to the top of the fixing frame 31.

[0033] The effects achieved by the above components are as follows: the fixed frame 31 provides a stable mounting carrier for the fuel filter 32 and the fuel pump 33, ensuring that neither of them will shift or loosen during the operation of the carburetor, thus ensuring the structural stability of the fuel supply system. As a power source, the fuel pump 33 can generate stable pressure to draw fuel from the fuel tank and deliver it to subsequent components. Its rated pressure and flow parameters match the atomization requirements of the carburetor, ensuring sufficient fuel supply and stable pressure. The fuel filter 32 can efficiently filter out impurities, gum, moisture and other contaminants in the fuel, preventing contaminants from clogging the pre-atomization hole 223 or wearing atomization components, extending the service life of the atomization components, and ensuring fuel cleanliness to improve atomization effect.

[0034] Specifically, a suction pipe 34 is fixedly connected to one side of the outer surface of the fuel pump 33, and an oil pipe 35 is fixedly connected to the other side of the outer surface of the fuel pump 33. One end of the oil pipe 35 is fixedly connected to the inside of the fuel filter 32, and the fuel filter 32 is precisely aligned with the outer surface of the pre-atomizing cone spray head 221.

[0035] The effects achieved by the above components are as follows: the suction pipe 34 serves as the initial channel for fuel extraction, and its oil-resistant material can adapt to the fuel environment, ensuring that fuel can smoothly enter the fuel pump 33 from the fuel tank. The fuel pipe 35 stably delivers the fuel output from the fuel pump 33 to the fuel filter 32. Its flexibility and corrosion resistance ensure the smoothness and durability of the fuel delivery path. The precise docking between the fuel filter 32 and the pre-atomizing cone spray head 221 allows the filtered clean fuel to directly enter the pre-atomizing cone spray head 221, reducing fuel retention or leakage during the delivery process and ensuring that the fuel enters the pre-atomizing hole 223 with stable pressure and flow, thus providing a guarantee for the stability of the initial atomization effect.

[0036] Working principle: When the internal combustion engine starts, the fuel pump 33 starts to work, drawing fuel from the fuel tank through the suction pipe 34. The fuel is then transported to the fuel filter 32 through the fuel pipe 35. The fuel filter 32 performs deep filtration on the fuel, removing impurities, gum and other contaminants, and then accurately delivers the clean fuel to the pre-atomizing cone spray head 221 in the initial atomization chamber 225. After clean fuel enters the pre-atomizing cone spray head 221, it is sprayed out through multiple pre-atomizing holes 223 on its outer surface under the pressure provided by the fuel pump 33, forming a small-diameter initial oil mist. The initial oil mist enters the air mixing atomization chamber 226 under the action of airflow. At this time, the air required in the air mixing atomization chamber 226 is provided by the air intake assembly 23. The external air is first pre-filtered by the air preliminary filter screen 235 in the air intake pipe 232, and then deeply purified by the air filter 231. At the same time, the air flow sensor 233 detects the intake air flow in real time and feeds back the data. The purified air enters the air mixing atomization chamber 226 through the air connecting pipe 234, which pushes the spiral guide plate 222 to rotate around the rotating bearing 227. The rotating guide plate further shears and stirs the initial oil mist, making the oil mist particles finer and atomized, thus achieving staged atomization. Under the rotation of the spiral guide plate 222, the refined oil mist and clean air are fully intertwined and mixed along the spiral path to form a uniform combustible mixture. During this process, the control unit adjusts the fuel supply of the fuel pump 33 in real time according to the detection data of the air flow sensor 233 to ensure that the air-fuel ratio is maintained within the ideal range. A uniform combustible mixture is delivered to the internal combustion engine cylinder through the intake manifold 25 on one side of the carburetor body 1. Under the ignition of the spark plug, it burns and does work. Throughout the process, the sealing gasket 21 and the connecting bolt 24 ensure that there is no leakage at each connection point. The fixed circular plate 224 maintains the independent working space of the initial atomization chamber 225 and the air mixing atomization chamber 226, ensuring the overall stable operation.
