Description

Technical Field

[0001] This invention relates to the field of oil supply equipment technology, specifically to a steam-type cold fogger oil supply system. Background Technology

[0002] Traditional fogging machine fuel supply systems mostly use plunger pumps with mechanical throttle valves to achieve overall fuel supply. However, traditional plunger pumps have low flow rates and relatively weak suction, often resulting in untimely fuel supply. Furthermore, the mechanical throttle valves are not sensitive and have poor control precision. When the machine is subject to elevation differences or movement during operation, untimely fuel supply often occurs. Moreover, gasoline inside the pump body will generate bubbles over long-term use, causing corrosion or damage to internal parts. Therefore, a steam-type fogging machine fuel supply system is needed. Summary of the Invention

[0003] The purpose of this invention is to provide a steam-type cold fog generator oil supply system to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a steam-type cold fog generator oil supply system, comprising an oil storage tank, a first connector connected to the outside of the oil storage tank, a first connecting hose connected to the end of the first connector away from the oil storage tank, an air pump installed at the end of the first connecting hose away from the first connector, an oil outlet regulating structure installed outside the oil storage tank, a burner installed outside the oil outlet regulating structure, a pneumatic oil control ignition control mechanism installed inside the burner, and a pressure regulating structure installed outside the oil storage tank.

[0005] Preferably, the oil outlet regulating structure includes a second connector, which is connected to the oil storage tank. The end of the second connector away from the oil storage tank is connected to a second connecting hose. A solenoid valve is installed at the end of the second connecting hose away from the second connector. The oil outlet of the solenoid valve is connected to an oil supply pipe. The end of the oil supply pipe away from the solenoid valve is connected to the oil inlet of the burner.

[0006] Preferably, the pneumatic oil-controlled ignition control mechanism includes a spark plug, which is installed on the front end cover of the burner, and a flame sensor is installed inside the burner.

[0007] Preferably, the pressure regulating structure includes a pressure switch, which is installed on the outside of the oil storage tank. A pressure relief valve is installed on the outside of the oil storage tank. The control output terminals of the pressure switch and the solenoid valve are connected to a microcontroller via wires.

[0008] Preferably, the oil storage tank is equipped with a sealed top cover.

[0009] Preferably, the end of the first connecting hose away from the first connector is snapped into the air outlet of the air pump.

[0010] Preferably, the flame sensor includes a photoresistor for detecting the light source signal in the burner and activating or deactivating the spark plug.

[0011] Preferably, the flame sensor includes a thermocouple for detecting heat in the burner and activating or deactivating the spark plug.

[0012] Preferably, the flame sensor includes an ion ignition needle for detecting the flame ion state and activating or deactivating the spark plug.

[0013] Preferably, a transparent observation tube is installed on the outside of the oil storage tank.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] In this invention, the oil tank is pressurized by starting an air pump, so that the oil is delivered to the second connector and the second connecting hose by pressure. The oil is then delivered to the inside of the burner by an oil delivery pipe through a solenoid valve. The pressure value is monitored by a pressure relief valve, and automatic pressure relief is performed when the pressure value is too high to ensure safety.

[0016] In this invention, the opening and closing time of the solenoid valve is controlled by a microcontroller, thereby adjusting the amount of oil entering the burner. During ignition, a longer opening time and a shorter closing time result in a larger oil output, making ignition easier. Once combustion is successful, the opening time is reduced and the closing time is lengthened to reduce the oil supply and save oil usage. The entire system is powered by an air pump, avoiding direct contact between the oil and the pump body, reducing oil corrosion and extending the pump's lifespan. The system is stable, easy to control, and maintains constant pressure. The use of a microcontroller for control makes overall control faster and more precise, avoiding situations where the control is insensitive.

[0017] In this invention, during the burner ignition process, after the solenoid valve supplies oil in conjunction with the oil supply pipe, ignition is achieved through the spark plug. Once ignition is successful, the flame sensor detects the flame, heat, and flame ionization state inside the burner and then stops the spark plug from working. However, if the burner unexpectedly stops working midway, the flame sensor detects the absence of flame, heat, and flame ionization inside the burner and then continuously starts the spark plug for ignition, forming a closed-loop control. This results in a relatively stable flow rate and a relatively stable and rapid ignition process, avoiding situations where ignition is not timely. Attached Figure Description

[0026] Example 1

[0027] Please see Figures 1-6 The present invention provides a technical solution:

[0028] A steam-type cold fogger oil supply system includes an oil storage tank 10. A first connector 11 is externally connected to the oil storage tank 10. A first connecting hose 12 is connected to the end of the first connector 11 away from the oil storage tank 10.

The oil storage tank 10 stores oil, and the air pump 13 is externally connected to it via the first connector 11 and the first connecting hose 12. Gas is injected into the oil storage tank 10 by the air pump 13, creating air pressure inside the oil storage tank 10, thereby pressurizing the oil and delivering it to the oil outlet regulating structure.

The opening and closing of the solenoid valve 22 will restrict the entry and exit of the oil. When the solenoid valve 22 is opened, the oil enters the interior of the oil delivery pipe 23. The oil delivery pipe 23 will deliver the oil to the interior of the burner 24.

[0031] like Figures 4-6 As shown, the pneumatic oil-controlled ignition control mechanism consists of a spark plug 30, which is installed on the front end cover of the burner 24, and a flame sensor 31 is installed inside the burner 24.

[0032] like Figures 4-6 As shown, the principle of the pneumatic oil-controlled ignition mechanism is as follows: In the pneumatic oil-controlled ignition mechanism, the spark plug 30 is used to ignite the inside of the burner 24. The spark plug 30 is an electric ignition device. The flame sensor 31 is set to detect whether there is light inside the burner 24. When the flame sensor 31 does not detect any light, the spark plug 30 is activated to ignite the burner.

[0033] like Figure 2 As shown, the pressure regulating structure consists of a pressure switch 40, which is installed outside the oil storage tank 10.

[0034] like Figure 2 As shown, the principle of the pressure regulation structure is as follows: In the pressure regulation structure, the pressure value inside the oil storage tank 10 is monitored by the pressure switch 40 and the pressure relief valve 41. When the pressure is too high, the pressure is quickly relieved by the pressure relief valve 41 to ensure the pressure stability and safety inside the oil storage tank 10. The whole system is controlled by the microcontroller 42.

[0038] like Figures 1-3 As shown, the oil outlet regulating structure consists of: a second connector 20, which is connected to the oil storage tank 10; a second connecting hose 21 is connected to the end of the second connector 20 away from the oil storage tank 10; the second connecting hose 21 is connected to the oil inlet of the solenoid valve 22; an oil supply pipe 23 is connected to the oil outlet of the solenoid valve 22; and the end of the oil supply pipe 23 away from the solenoid valve 22 is connected to the oil inlet of the burner 24.

[0039] like Figures 1-3 As shown, the principle of the oil outlet adjustment structure is as follows: In the oil outlet adjustment structure, the oil storage tank 10 and the second connecting hose 21 are connected through the second connector 20. The oil is connected to the second connecting hose 21 through the second connector 20. The second connecting hose 21 delivers the oil to the solenoid valve 22. The opening and closing of the solenoid valve 22 restricts the inflow and outflow of the oil. The oil enters the oil inlet of the solenoid valve 22 through the second connecting hose 21 and is delivered to the inside of the oil supply pipe 23 through the oil outlet of the solenoid valve 22. When the solenoid valve 22 is opened, the oil enters the inside of the oil supply pipe 23, and the oil supply pipe 23 delivers the oil to the inside of the burner 24.

[0044] To ensure the airtightness of the oil storage tank 10, a sealing cover 50 is installed on the oil storage tank 10.

[0045] Specifically, the flame sensor 31 includes an ion ignition needle for detecting the flame ion state and activating or deactivating the spark plug 30.

[0046] Example 3 differs from Examples 2 and 1 in that...

[0047] A steam-type cold fogger oil supply system includes an oil storage tank 10, an external connection to the oil storage tank 10 via a first connector 11, a first connecting hose 12 connected to the end of the first connector 11 away from the oil storage tank 10, an air pump 13 connected to the end of the first connecting hose 12 away from the first connector 11, an oil outlet regulating structure installed on the outside of the oil storage tank 10, a burner 24 installed on the outside of the oil outlet regulating structure, a pneumatic oil control ignition control mechanism installed inside the burner 24, and a pressure regulating structure installed on the outside of the oil storage tank 10.

[0048] like Figures 1-3 As shown, the oil outlet regulating structure consists of: a second connector 20, the oil inlet of the second connector 20 being connected to the oil storage tank 10, the oil outlet of the second connector 20 being connected to a second connecting hose 21, the second connecting hose 21 being connected to the oil inlet of the solenoid valve 22, the oil outlet of the solenoid valve 22 being connected to an oil supply pipe 23, and the oil outlet of the oil supply pipe 23 being connected to the oil inlet of the burner 24.

[0049] like Figures 1-3As shown, the principle of the oil outlet adjustment structure is as follows: In the oil outlet adjustment structure, the oil storage tank 10 and the second connecting hose 21 are connected through the second connector 20. The oil is connected to the second connecting hose 21 through the second connector 20. The second connecting hose 21 delivers the oil to the solenoid valve 22. The opening and closing of the solenoid valve 22 restricts the inflow and outflow of the oil. The oil enters the oil inlet of the solenoid valve 22 through the second connecting hose 21 and is delivered to the inside of the oil supply pipe 23 through the oil outlet of the solenoid valve 22. When the solenoid valve 22 is opened, the oil enters the inside of the oil supply pipe 23, and the oil supply pipe 23 delivers the oil to the inside of the burner 24.

[0050] like Figures 4-6 As shown, the pneumatic oil-controlled ignition control mechanism consists of a spark plug 30, which is installed on the front end cover of the burner 24. A flame sensor 31 is installed at the opening of the front end cover of the burner 24.

[0051] like Figures 4-6 As shown, the principle of the pneumatic oil-controlled ignition mechanism is as follows: In the pneumatic oil-controlled ignition mechanism, the spark plug 30 is used to ignite the inside of the burner 24. The spark plug 30 is an electric ignition device. The flame sensor 31 is set to detect whether there is light inside the burner 24. When the flame sensor 31 does not detect any light, the spark plug 30 is activated to ignite the burner.

[0052] like Figure 2 As shown, the pressure regulating structure consists of a pressure switch 40, which is installed outside the oil storage tank 10. A pressure relief valve 41 is connected to the oil storage tank 10 to monitor the internal pressure value of the oil storage tank 10. A microcontroller 42 is electrically connected to the pressure switch 40 and the solenoid valve 22.

[0053] like Figure 2 As shown, the principle of the pressure regulation structure is as follows: In the pressure regulation structure, the pressure value inside the oil storage tank 10 is monitored by the pressure switch 40 and the pressure relief valve 41. When the pressure is too high, the pressure is quickly relieved by the pressure relief valve 41 to ensure the pressure stability and safety inside the oil storage tank 10. The whole system is controlled by the microcontroller 42.

[0054] Specifically, the flame sensor 31 includes a photoresistor for detecting the light source signal in the burner 24 and activating or deactivating the spark plug 30.

[0055] Specifically, a transparent observation tube 51 is installed on the outside of the oil storage tank 10.

[0056] Based on the above technical solution, the working steps of this solution are summarized as follows: During use, the air pump 13 is started to pressurize the inside of the oil storage tank 10, so that the oil is delivered to the second connector 20 and the second connecting hose 21 through pressure. The solenoid valve 22, in conjunction with the oil delivery pipe 23, delivers the oil to the inside of the burner 24. The pressure value is monitored by the pressure relief valve 41. When the pressure value is too high, the pressure relief valve 41 automatically releases pressure when the oil storage tank 10 reaches the maximum pressure value. The pressure value is set by the sensor in the microcontroller 42. When the oil storage tank 10 reaches the set value, the air pump 13 stops working. At the same time, the pressure switch 40 can release pressure in advance to prevent the pressure from adhering to the sealing cover 50, making it easier to open the sealing cover 50 and ensuring safety. The microcontroller 42 controls the opening and closing time of the solenoid valve 22 to adjust the oil flow into the burner 24. During ignition, the opening time is long and the closing time is short, resulting in a larger oil output. The burner 24 is relatively easy to ignite. After successful combustion, the opening time is reduced and the closing time is increased, thus reducing the oil supply and saving oil usage. The entire system is powered by an air pump 13, avoiding direct contact between the oil and the pump body, reducing oil corrosion and extending the service life of the air pump 13. The system is stable and easy to control, with constant overall pressure. It is controlled by a single-chip microcomputer 42, making the overall control faster and more precise, avoiding insensitive control. During the ignition process of the burner 24, the solenoid valve 22 supplies oil in conjunction with the oil supply pipe 23, and then ignites it through the spark plug 30. When ignition is successful, the flame sensor 31 detects a flame inside the burner 24 and stops the spark plug 30 from working. If the burner 24 unexpectedly stops working midway, the flame sensor 31 detects no flame inside the burner 24 and continues to start the spark plug 30 for ignition, forming a closed-loop control. The flow rate is relatively stable, and the ignition process is relatively stable and fast, avoiding untimely ignition.
