By arranging the solenoid valve coil in the valve body, slidingly arranging the magnetic attraction piece on the valve body, and arranging the thermocouple, one end of the thermocouple is used to detect the temperature, so that the thermocouple can make the solenoid valve coil generate a magnetic field to attract the magnetic attraction piece, by arranging the first electric contact and the second electric contact on the magnetic attraction piece and the solenoid valve coil or the valve body, the first electric contact and the second electric contact are connected with the control circuit, so that when the magnetic attraction piece is moved by the electric push rod at the beginning, the first electric contact and the second electric contact are in contact, thereby connecting the control circuit, achieving the purpose of igniting and controlling fuel delivery by the control circuit. When the thermocouple generates current due to heating, the magnetic attraction piece is attracted by the solenoid valve coil to keep the first electric contact and the second electric contact in contact, at this time, the control circuit is continuously connected to make the flame continue to burn.

By arranging the induction wire, the sensitivity of the temperature sensing probe to the flame is higher, the detection capability is stronger, and the work is more stable, so that the judgment of the extinguished fire is more accurate.

[0011] Specifically, the induction wire is in a vortex structure and arranged around the combustion zone. Since the flame may swing during combustion, the detection range of the temperature sensing probe is limited, which may affect the detection result.

[0023] As Figures 1 to 4As shown, the utility model discloses an integral plant oil fuel stove 100 including stove body 1 and setting on stove body 1 fuel tank 2, fuel passage 3, shower nozzle 4, igniter 5, control circuit 6, electromagnetic valve switch 7 and flameout power-off protection device 8, stove body 1 is equipped with furnace body 11, furnace body 11 is located stove body 1's surface and is recessed structure to the down, forms an upside open space, and the opening can be used for carrying the stove. Shower nozzle 4 sets up in stove body 11's bottom intermediate position. Shower nozzle 4 is connected with one end of fuel passage 3, and the other end of fuel passage 3 is connected with fuel tank 2, to output liquid fuel to shower nozzle 4. The fuel of the utility model is plant oil fuel. Fuel tank 2 sets up in stove body 1's downside, fuel tank 2 has oil filler 21, and oil filler 21 sets up in stove body 1's surface. The horizontal height of fuel tank 2 is greater than the horizontal height of shower nozzle 4. This can make fuel liquid in fuel tank 2 can flow to shower nozzle 4 under the action of gravity, need not use pump body to provide output power for fuel. Stove body 1, fuel tank 2 and furnace body 11 are integrally formed structure. Furnace body 11 and fuel tank 2 are equipped with heat insulation layer. The utility model discloses an integral plant oil fuel stove 100 is with plant oil as fuel, and the nature of plant oil is stable, and it is not easy to volatilize, and it is not easy to explode, ignite in the air, and it is very safe to use, therefore, through making stove body 1, fuel tank 2 and furnace body 11 integrally formed structure, and setting fuel tank 2 oil filler on the surface of stove 11, so that fuel can be directly poured into fuel tank 2 when refueling, its structure is simple, need not to dismount fuel tank 2, need not to replace fuel tank 2, and need not to worry about explosion or poisoning problem, and the use safety is high. Igniter 5 sets up in one side inside furnace body 11 and is close to shower nozzle 4, and igniter 5 is electrically connected with control circuit 6. Electromagnetic valve switch 7 sets up on fuel passage 3 to control fuel passage 3 on-off, and electromagnetic valve switch 7 is electrically connected with control circuit 6, when control circuit 6 is powered on, electromagnetic valve switch 7 is in open state, to open fuel passage 3, so that fuel can be output to shower nozzle 4, when control circuit 6 is powered off, electromagnetic valve switch 7 is in closed state, to close fuel passage 3, so that fuel pauses to shower nozzle 4 delivery. Flameout power-off protection device 8 sets up on control circuit 6, and temperature sensing probe 841 of flameout power-off protection device 8 sets up in furnace body 11 and is close to shower nozzle 4, to detect the flame near shower nozzle 4 control circuit 6 on-off. Specifically, when flameout power-off protection device 8 detects that there is flame burning in furnace body 11, flameout power-off protection device 8 controls control circuit 6 to keep powered on, when flameout power-off protection device 8 detects that the flame in furnace body 11 is extinguished, flameout power-off protection device 8 powers off control circuit 6. More specifically, as follows:

[0024] Please see again Figure 3 As shown, the flameout protection device 8 includes a valve body 81, a solenoid valve coil 82, a magnetic chuck 83, a thermocouple 84, a first electrical contact 85, a second electrical contact 86, an elastic reset member 87, and an electric push rod 88. The solenoid valve coil 82 is disposed on the valve body 81. One end of the thermocouple 84 is a temperature sensing probe 841, and the other end of the thermocouple 84 is electrically connected to the solenoid valve coil 82. The magnetic chuck 83 is slidably disposed on the valve body 81. The first electrical contact 85 is disposed on the magnetic chuck 83, and the second electrical contact 86 is disposed on the valve body 81 or the solenoid valve coil 82. The first electrical contact 85 and the second electrical contact 86 are respectively connected to the two ends of the control circuit 6. The telescopic end of the electric actuator 88 is positioned opposite the magnetic chuck 83, so that when the telescopic end extends, it pushes the magnetic chuck 83 toward the solenoid valve coil 82, causing the first electrical contact 85 to make conductive contact with the second electrical contact 86, thereby connecting the control circuit 6. The elastic reset member 87 is disposed between the valve body 81 and the magnetic chuck 83. When the magnetic force of the solenoid valve coil 82 disappears, its elastic force can separate the first electrical contact 85 from the second electrical contact 86, thereby cutting off the control circuit 6; the elastic reset member 87 is a compression spring.

[0025] Please see again Figure 3 As shown, the flameout power-off protection device 8 also includes an execution circuit 89, which is electrically connected to the electric push rod 88. The execution circuit 89 includes a time relay 891 and a start switch 892. The time relay 891 controls the on / off time of the execution circuit 89. When the start switch 892 is pressed to start the execution circuit 89, the telescopic end of the electric push rod 88 extends, thereby pushing the magnetic suction member 83 toward the direction close to the solenoid valve coil 82. At the same time, the time relay 891 starts timing. When the time relay 891 finishes timing, the execution circuit 89 is de-energized, and the telescopic end of the electric push rod 88 leaves the magnetic suction member 83. By setting the time relay 891, the energizing time of the electric push rod 88 can be controlled at regular intervals; after the power is cut off, the magnetic attracting member 83 is only subjected to the magnetic attraction of the solenoid valve coil 82 and the elastic restoring force of the elastic reset member 87. Therefore, when the flame is extinguished, the magnetic attraction disappears, and the elastic force of the elastic reset member 87 can be used to cut off the control circuit 6.

[0026] Please see again Figure 2 and Figure 4As shown, the flameout power-off protection device 8 further comprises an induction wire 810, which is arranged in the combustion zone and connected with the temperature induction probe 841 of the thermocouple 84. By arranging the induction wire 810, the sensitivity of the temperature induction probe 841 to the flame is higher, the detection capability is stronger, and the work is more stable, thereby ensuring the judgment of the flameout. The induction wire 810 is a spiral spring. In this way, sufficient elastic space can be provided when the induction wire 810 is spirally wound, the installation is more flexible, the extended length is greater, the service life is longer, and the accuracy is higher. Specifically, the induction wire 810 is arranged in a spiral structure around the combustion zone. Since the flame may swing during combustion, the detection range of the temperature induction probe 841 is limited, which may affect the detection result. Therefore, by arranging the induction wire 810 in a spiral structure, the detection range of the temperature induction probe 841 can be further increased, and the detection accuracy can be ensured. The induction wire 810 is made of nickel or nickel alloy material.

[0027] Please refer to Figure 1 and Figure 3 As shown, the integrated vegetable oil fuel stove 100 further comprises a flow control valve 9 arranged in the fuel channel 3 and electrically connected with the control circuit 6. By arranging the flow control valve 9, the flow of the fuel can be controlled, thereby controlling the fuel ejection amount of the spray head 4, achieving the purpose of controlling the fire size, and improving the convenience of use.

[0028] Please refer to Figure 1 and Figure 3 As shown, the integrated vegetable oil fuel stove 100 further comprises a gas supply device 10, the output end of the gas supply device 10 being communicated with the spray head 4 to blow out the fuel in the spray head 4. High-pressure air containing oxygen enters the inside of the spray head 4 from the gas port of the spray head 4, mixes with the fuel entering from the oil port of the spray head 4, and is sprayed from the spray port of the spray head 4 into the inside of the stove body 11, thereby making the fuel easier to burn. The gas supply device 10 comprises a gas pump and a gas valve, the output end of the gas pump being connected with the input end of the gas valve, and the input end of the gas pump being communicated with the outside. The output end of the gas valve is connected with the spray head and electrically connected with the control circuit to control the gas amount sprayed to the spray head. Of course, the gas supply device can also adopt a mode of directly connecting the gas pump with the spray head for gas supply.

[0029] In combination with the above description and the above drawings, the working principle of the integrated vegetable oil fuel stove 100 of the present application will be described in detail as follows:

[0030] When the integrated plant oil fuel stove 100 is needed to be used, the start switch 892 is pressed, so that the execution circuit 89 is powered on, at the same time, the time relay 891 starts timing, at this time, the electric push rod 88 is powered on, the execution circuit 89 controls the electric push rod 88, so that the telescopic end of the electric push rod 88 is extended. At this time, the telescopic end of the electric push rod 88 pushes the magnetic attraction piece 83, so that the magnetic attraction piece 83 moves towards the direction close to the electromagnetic valve coil 82. Finally, the first electric contact 85 and the second electric contact 86 are in electrical contact, and the control circuit 6 is powered on. After the control circuit 6 is powered on, the electromagnetic valve switch 7 is turned on and the fuel channel 3 is opened, and the fuel in the fuel tank 2 flows to the spray head 4 through the fuel channel 3. At the same time, the control circuit controls the air pump, ignition and flow control valve 9 to be in the powered-on state. Specifically, the air pump is started to blow air to the spray head 4, so that the fuel in the spray head 4 is mixed with air and then sprayed from the spray head 4 into the furnace body 11. At this time, only the button of the igniter 5 needs to be operated, so that the igniter 5 is started to generate sparks, and thus the sparks ignite the mixed combustible gas in the furnace body 11, so that the spray head 4 generates flame combustion. By controlling the flow control valve 9, the spray head 4 continuously sprays fuel to realize continuous combustion. In the initial stage of flame combustion, the flame heats the sensing wire 810, and after the sensing wire 810 detects the flame, an electric current is generated in the thermocouple 84, which makes the electromagnetic valve coil 82 generate a magnetic field, and the magnetic field generates an attractive force on the magnetic attraction piece 83, which is greater than the elastic restoring force of the elastic reset piece 87. Therefore, the magnetic attraction piece 83 can be continuously attracted by the electromagnetic valve coil 82, so that the control circuit 6 remains conductive, thereby making the electromagnetic valve switch 7, the air pump and other execution elements continuously work.

[0031] When the time relay 891 finishes timing (usually set to 60 seconds), the time relay 891 cuts off the execution circuit 89, at this time, the telescopic end of the electric push rod 88 retracts and leaves the magnetic attraction piece 83, and because the electromagnetic valve coil 82 continuously attracts the magnetic attraction piece 83 at this time, the flame in the furnace 11 can still continuously burn. However, when the flame is accidentally extinguished, the sensing wire 810 cools, the thermocouple 84 cannot generate current, so that the magnetic field of the electromagnetic valve coil 82 disappears, at this time, the magnetic attraction piece 83 is away from the electromagnetic valve coil 82 under the elastic force of the elastic reset piece 87, at this time, the first electric contact 85 and the second electric contact 86 are separated, so that the control circuit 6 is powered off. Therefore, the electromagnetic valve switch 7, the air pump, the igniter 5 and the flow control valve 9 and other execution elements stop working. The electromagnetic valve switch 7 will close the fuel passage 3 again, so that fuel cannot be sent to the spray head 4, and the spray head 4 cannot spray combustible gas to the furnace 11, so that the accident of toxic gas leakage in the furnace 11 does not occur, and each electric equipment is in a power-off state, the power is saved, and the safety of use is greatly improved.

[0032] The utility model discloses a magnetic attraction piece 83 is slidably arranged in the valve body 81 through setting electromagnetic valve coil 82 in the valve body 81, and the magnetic attraction piece 83 is slidably arranged in the valve body 81, and through setting thermocouple 84, one end of thermocouple 84 is used to detect temperature, so that the electromagnetic valve coil 82 can produce the magnetic field of attracting the magnetic attraction piece 83 by thermocouple 84, first electric contact 85 and second electric contact 86 are arranged on the magnetic attraction piece 83 and the electromagnetic valve coil 82 or valve body 81, the first electric contact 85 is connected with second electric contact 86 and control circuit 6, so that when starting, the magnetic attraction piece 83 is moved by the electric push rod 88, so that the first electric contact 85 and second electric contact 86 contact, so that control circuit 6 can be connected, the purpose of using control circuit 6 to ignite and controlling fuel delivery by electromagnetic valve switch 7 is achieved. When thermocouple 84 generates current by heating, the magnetic attraction piece 83 is attracted by the electromagnetic valve coil and makes first electric contact 85 and second electric contact 86 keep contact, at this time, control circuit 6 can be continuously connected, so that the electromagnetic valve switch 7 is opened, and then the flame is continuously burned. Conversely, when the flame is accidentally extinguished, the thermocouple 84 cools, the magnetic attraction piece 83 is pushed away from the electromagnetic valve coil 82 by the elastic reset piece 87, so that the first electric contact 85 and the second electric contact 86 are separated, and the purpose of cutting off control circuit 6 is realized, so that the electromagnetic valve switch 7 closes the fuel passage 3, and fuel leakage is avoided. Therefore, the scheme can automatically disconnect power supply and disconnect fuel delivery after accidental extinguishing, prevent electric equipment from continuing to work, effectively prolong the service life of electric equipment, fuel leakage and improve the safety of use.

[0033] The working principles of the control circuit 6 and the execution circuit 89 of the integrated vegetable oil fuel stove 100 are well known to those skilled in the art, and will not be described in detail here.

[0034] The above is only a preferred embodiment of the present application, and of course cannot limit the scope of the present application, so the equivalent changes made according to the patent application scope of the present application still belong to the scope covered by the present application.
