[0039] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0040] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0041] Example:

[0042] See Figure 1 and Figure 2 Based on the same inventive concept, the first aspect of this application discloses a multi-point fuel supply device with a mixing function, which includes a base 100, a fuel delivery structure 200, a lubricating oil delivery structure 300, and a connector structure 400. The fuel delivery structure 200 is mounted on the base 100, and the lubricating oil delivery structure 300 is also mounted on the base 100, with the lubricating oil delivery structure 300 and the fuel delivery structure 200 spaced apart. The connector structure 400 includes a mixing pipe 410 and multiple fuel outlets 420 connected to the mixing pipe 410, with the fuel outlets 420 spaced apart. The mixing pipe 410 is connected to the fuel delivery structure 200 via a first pipe 430, and the mixing pipe 410 is connected to the lubricating oil delivery structure 300 via a second pipe 440.

[0043] The multi-point fuel supply device with oil mixing function disclosed in this embodiment achieves multi-point fuel output by precisely controlling the delivery ratio and flow rate of fuel oil and lubricating oil, thus meeting the fuel needs under various complex working conditions.

[0044] In one embodiment, a first solenoid valve 230 and a first flow sensor 240 are provided on the first pipe 430, and a second solenoid valve 330 and a second flow sensor 340 are provided on the second pipe 440.

[0045] The first conduit 430 is responsible for conveying fuel from the fuel delivery structure 200 to the mixing conduit 410. The first solenoid valve 230 is used to control the on / off of fuel delivery, achieving precise regulation of fuel flow. The first flow sensor 240 monitors the fuel delivery flow in real time, ensuring that fuel is delivered according to the preset ratio and flow rate.

[0046] The second pipe 440 is responsible for conveying lubricating oil from the lubricating oil conveying structure 300 to the mixing pipe 410. The second solenoid valve 330 is used to control the on / off of lubricating oil delivery, realizing precise regulation of lubricating oil flow rate. The second flow sensor 340 monitors the lubricating oil delivery flow rate in real time to ensure that the lubricating oil is delivered according to the preset ratio and flow rate.

[0047] By setting a first solenoid valve 230, a first flow sensor 240, a second solenoid valve 330, and a second flow sensor 340, the present invention can achieve precise control of fuel and lubricating oil delivery, ensuring accurate oil-fuel ratio and stable flow rate after mixing.

[0048] In one embodiment, multiple first solenoid valves 230 are provided, and the multiple first solenoid valves 230 are spaced apart on the first pipe 430. Multiple second solenoid valves 330 are provided, and the multiple second solenoid valves 330 are spaced apart on the second pipe 440.

[0049] Three solenoid valves 230 or 330 are installed on the same pipeline, each capable of independently controlling the flow of media in its respective pipe section. These three valves can control different sections, enabling flexible adjustment of the media flow within the pipeline. For example, the flow rate or pressure of the media can be controlled by adjusting the opening degree of one of the solenoid valves. If one solenoid valve 230 or 330 fails, the others can still operate normally, ensuring the continuity and stability of the pipeline system. Furthermore, through redundant design (such as using three solenoid valves 230 or 330 instead of one or two), the risk of system failure due to the failure of a single component can be reduced.

[0050] In one embodiment, a one-way valve 500 is provided at the connection between the mixing pipe 410 and the first pipe 430 and the second pipe 440, so that fluid can only enter the mixing pipe 410 along the first pipe 430 and the second pipe 440.

[0051] To ensure that fuel and lubricating oil flow in a predetermined direction and prevent the mixed mixture from flowing back into the fuel delivery structure 200 or the lubricating oil delivery structure 300, this invention provides a one-way valve 500 at the connection between the mixing pipe 410 and the first pipe 430 and the second pipe 440. At the connection between the mixing pipe 410 and the first pipe 430, this invention provides a first one-way valve 500 to ensure that fuel can only flow into the mixing pipe 410 from the first pipe 430 and cannot flow in the reverse direction. Similarly, at the connection between the mixing pipe 410 and the second pipe 440, this invention provides a second one-way valve 500 to ensure that lubricating oil can only flow into the mixing pipe 410 from the second pipe 440 and cannot flow in the reverse direction.

[0052] By setting up a first check valve 500 and a second check valve 500, the present invention effectively controls the flow direction of fuel and lubricating oil, avoiding unnecessary interference or damage to the fuel delivery structure 200 and the lubricating oil delivery structure 300 caused by the mixed oil. At the same time, this also ensures the purity and stability of the oil in the mixing pipeline 410, improving the overall performance and reliability of the equipment.

[0053] In one embodiment, a filter separator 800 is also provided at the connection between the mixing pipe 410 and the first pipe 430 and the second pipe 440, and the filter separator 800 is used to filter the oil.

[0054] Fuel oil and lubricating oil may flow in from different sources through the first pipe 430 and the second pipe 440, and finally be mixed in the mixing pipe 410. However, since various impurities, such as solid particles, moisture or other contaminants, may be mixed into the fuel oil and lubricating oil during the transmission process, it is necessary to filter them before mixing.

[0055] A filter separator 800 is installed at the connection between the mixing pipe 410 and the first pipe 430 and the second pipe 440, for the purpose of filtering and separating the oil that is about to enter the mixing pipe 410. The filter separator 800 is usually equipped with precision filter elements, such as filter screens, filter cartridges or membrane separators, which can effectively remove solid particles, water and most contaminants from the oil.

[0056] Specifically, when the oil passes through the filter separator 800, impurities are trapped by the filter element, while the pure oil continues to flow into the mixing pipe 410. This not only ensures the quality of the mixed oil but also extends the service life of other equipment in the system, such as pumps, valves, and nozzles.

[0057] In one embodiment, a third flow sensor is installed on the mixing pipe 410. This third flow sensor is installed on the mixing pipe 410 to monitor the flow rate of the mixed oil in real time. Through the third flow sensor, users can intuitively understand the flow of the oil within the mixing pipe 410, including key information such as flow rate magnitude and flow stability. This is of great significance for adjusting the delivery ratio of fuel oil and lubricating oil, optimizing output flow, and improving equipment performance.

[0058] The inclusion of a third flow sensor not only enhances the transparency and controllability of equipment operation but also provides users with more accurate and reliable fuel flow data. By combining data from the first flow sensor 240 and the second flow sensor 340, users can further analyze the accuracy of the fuel and lubricating oil mixing ratio and take appropriate adjustment measures to ensure stable equipment operation and efficient fuel utilization.

[0059] In one embodiment, the delivery structure includes a fuel pump 220 and a fuel tank 210, with a first conduit 430 connected to the fuel tank 210. The fuel pump 220 delivers fuel from the fuel tank 210 into the first conduit 430. The fuel tank 210 stores fuel, ensuring sufficient fuel supply when needed. The fuel pump 220 is responsible for delivering fuel from the fuel tank 210 to the mixing conduit 410 via the first conduit 430. The fuel pump 220 is designed with the physical properties of the fuel, such as viscosity and density, in mind to ensure stable and continuous fuel delivery.

[0060] The lubricating oil delivery structure 300 includes an oil pump 320 and an oil tank 310. A second pipe 440 is connected to the oil tank 310. The oil pump 320 is used to deliver lubricating oil from the oil tank 310 into the second pipe 440. The oil tank 310 stores lubricating oil, providing necessary lubrication and protection for the equipment. The oil pump 320 is responsible for delivering the lubricating oil from the oil tank 310 to the mixing pipe 410 via the second pipe 440. The design of the oil pump 320 also takes into account the physical properties of the lubricating oil to ensure stable and continuous delivery.

[0061] It should be noted that although fuel oil and lubricating oil are transported to the mixing pipe 410 through different pipes (first pipe 430 and second pipe 440), they are mixed within the mixing pipe 410 to form a suitable oil mixture. This design ensures both independent transport of fuel oil and lubricating oil and their mixing, meeting the equipment's requirements for multiple oils.

[0062] In one embodiment, the multi-point fuel supply device with oil mixing function also includes an expansion interface, which is detachably coupled to the fuel outlet 420. The expansion interface is used for subsequent expansion, so that the end refueling component can be quickly connected to the multi-point fuel supply device with oil mixing function.

[0063] The expansion interface is designed to accommodate the connection needs of various end-point refueling components, ensuring a quick and stable connection with the equipment. Through the expansion interface, users can easily replace or expand end-point refueling components to meet fuel delivery requirements in different scenarios. This design not only improves the equipment's versatility and adaptability but also provides users with a more convenient operating experience. In practical applications, users can select the appropriate end-point refueling component as needed and connect it to the equipment via the expansion interface. This design ensures both the stability and reliability of the equipment while offering users greater choice and flexibility.

[0064] In one embodiment, a first pressure sensor is provided on the first pipe 430, a second pressure sensor is provided on the second pipe 440, and a third pressure sensor is provided on the mixing pipe 410.

[0065] The first pressure sensor is installed on the first pipe 430 to monitor pressure changes in real time during fuel delivery. This sensor allows the user to determine if the fuel is under sufficient pressure during delivery, ensuring a smooth and stable flow into the mixing pipe 410. The second pressure sensor, similar to the first, is installed on the second pipe 440 to monitor pressure changes in real time during lubricating oil delivery. This sensor allows the user to monitor the pressure status of the lubricating oil during delivery, ensuring it is delivered to the mixing pipe 410 at the predetermined pressure and flow rate. The third pressure sensor is installed on the mixing pipe 410 to monitor the pressure of the mixed fuel mixture. This sensor allows the user to determine if the pressure of the mixed fuel mixture is stable and if there are any abnormal pressure fluctuations. This is crucial for ensuring the stability and safety of the mixed fuel mixture.

[0066] In one embodiment, the multi-point fuel supply device with oil mixing function further includes a control box 600 and a control box 700. The control box 600 supplies power to the control box 700, fuel pump 220, lubricating oil pump 320, first pressure sensor, second pressure sensor, third pressure sensor, first flow sensor 240, second flow sensor 340, and third flow sensor. The control box 600 is equipped with appropriate power management modules and protection devices to ensure that suitable voltage and current are provided to each component under various operating conditions.

[0067] The control box 700 is the main interface for user interaction with the equipment. It integrates a controller. The first pressure sensor, second pressure sensor, third pressure sensor, first flow sensor 240, second flow sensor 340, and third flow sensor respectively collect pressure and flow data signals at their corresponding locations. These signals are then fed back to the controller within the control box 700. The controller uses these pressure and flow data signals to control the fuel pump 220, oil pump 320, and various solenoid valves to perform corresponding actions. For example, when the pressure in a certain pipeline exceeds a preset value, the controller can automatically adjust the fuel pump 220 or oil pump 320 to stop rotating to control the pressure; when a certain proportion of flow needs to be output, the controller can adjust the opening of the solenoid valve in the corresponding pipeline to regulate the flow.

[0068] Based on the same inventive concept, a second aspect of this application discloses a control method for a multi-point fuel supply device with oil mixing function based on any of the embodiments of the first aspect described above, which includes the following steps:

[0069] Set the required lubricating oil and fuel ratio;

[0070] Set the required total output of lubricating oil and fuel;

[0071] The controller controls the fuel delivery structure 200 and the lubricating oil delivery structure 300 to output fuel and lubricating oil respectively until the amount of fuel and lubricating oil delivered reaches the set total output.

[0072] The control method for a multi-point fuel supply device with mixing function disclosed in this application meets the requirements for high-precision fuel supply by precisely controlling the output ratio and total amount of fuel oil and lubricating oil. Furthermore, this control method is simple, easy to implement, and applicable to various occasions requiring precise mixing and output control.

[0073] In one embodiment, the step of the controller controlling the fuel delivery structure 200 and the lubricating oil delivery structure 300 to output fuel and lubricating oil respectively until the amount of fuel and lubricating oil delivered reaches the set output amount includes:

[0074] When the third flow sensor detects that the flow rate output from the mixing pipe 410 is equal to the set total output; and / or

[0075] When the sum of the flow rate output from the first pipe 430 detected by the first flow sensor 240 and the flow rate output from the second pipe 440 detected by the second flow sensor 340 equals the set total output;

[0076] The controller stops the output of the fuel delivery structure 200 and the lubricating oil delivery structure 300.

[0077] When the third flow sensor detects that the flow rate output from the mixing pipe 410 reaches a preset value, that is, the flow rate equals the set total output, it indicates that the mixed fuel has met the user's needs. Simultaneously, the system can also monitor the output flow rates of the fuel pipe and lubricating oil pipe through the first flow sensor 240 and the second flow sensor 340, respectively. When the sum of the fuel flow rate detected by the first flow sensor 240 and the lubricating oil flow rate detected by the second flow sensor 340 equals a preset value, it also indicates that the total output fuel has met the user's needs.

[0078] When any of the above conditions are met (i.e., the flow rate in the mixing pipe 410 reaches the set value, or the sum of the flow rates in the fuel and lubricating oil pipes reaches the set value), the controller will receive a corresponding signal. The controller will then execute a stop output command, sending stop signals to the fuel delivery structure 200 and the lubricating oil delivery structure 300 respectively, ensuring that both stop outputting fuel. After stopping the output, the controller will further verify the readings of each sensor to ensure that the fuel output has indeed stopped and that the total amount set by the user has been reached. If any abnormality or error exists (such as sensor failure, pipe blockage, etc.), the controller will trigger the corresponding alarm or error handling mechanism.

[0079] The control method in this embodiment provides dual protection by simultaneously monitoring the flow rates of the mixing pipe 410 and the individual pipes, ensuring the accuracy and reliability of fuel output. Furthermore, it can promptly stop output when the set output volume is reached, avoiding fuel waste and excessive equipment wear.

[0080] In one embodiment, pressure thresholds are set for the first pipe 430, the second pipe 440, and the mixing pipe 410;

[0081] The pressure within the first conduit 430 is greater than or equal to a set threshold; and / or

[0082] The pressure within the second conduit 440 is greater than or equal to a set threshold; and / or

[0083] When the pressure in the mixing pipe 410 is greater than or equal to a set threshold;

[0084] The controller stops the output of the fuel delivery structure 200 and the lubricating oil delivery structure 300.

[0085] Before starting the equipment or during operation, the user needs to set the pressure thresholds for the first pipeline 430 (fuel pipeline), the second pipeline 440 (lubricating oil pipeline), and the mixing pipeline 410 according to the actual conditions of the equipment and the characteristics of the oil. These thresholds are used to determine whether the pressure in the pipelines is within a safe range. During operation, the equipment continuously monitors the pressure values ​​in the pipelines in real time using pressure sensors installed on each pipeline. These pressure sensors transmit the detected pressure data to the controller in real time so that the controller can make subsequent judgments and processes.

[0086] When the controller receives data from the pressure sensor, it immediately performs a pressure assessment. If the pressure in the first pipe 430, the second pipe 440, or the mixing pipe 410 is greater than or equal to a set threshold, the controller considers the equipment to be in an unsafe state. In this case, the controller immediately sends a stop signal to the fuel delivery structure 200 and the lubricating oil delivery structure 300 to ensure that both stop supplying oil, thereby preventing equipment damage or safety accidents.

[0087] When the controller triggers a stop output command, it will also simultaneously activate an alarm mechanism to alert the user that the equipment is in an abnormal state. The user can check the specific condition of the equipment based on the alarm information and take appropriate troubleshooting measures. If the fault cannot be resolved immediately, the user can choose to shut down the equipment and contact a professional repair technician for inspection.

[0088] When setting the pressure thresholds for the first pipe 430, the second pipe 440, and the mixing pipe 410, the pressure thresholds for the first pipe 430, the second pipe 440, and the mixing pipe 410 can be set to the same value, or the pressure thresholds for the first pipe 430, the second pipe 440, and the mixing pipe 410 can be set to different values ​​depending on the situation.
