Description

Technical Field

[0001] The utility model relates to the field of fuel oil heating, in particular to a fuel oil air heating device linked with carbon monoxide detection. Background Art

[0002] When the ambient temperature is too low, people working or sleeping outdoors need a heating device for heating, but it is generally impossible to get AC power for air conditioning or electric heaters for heating outdoors. Even if a removable battery is used to power the heater or air conditioner for heating, the electric heating efficiency is low, the heating speed is slow, and the heater power requirement is large, so the power stored in the battery cannot support long-term heating operation and cannot meet people's heating needs outdoors in low temperatures.

[0003] Since fuel combustion heating is highly efficient, fast, and easy to carry and store, fuel air heaters have appeared on the market. Their working principle is to burn fuel in the combustion chamber, and the heat from the combustion is used to heat the combustion chamber. The airflow is then generated by the blower to bring the heat from the combustion chamber to the working and sleeping spaces where people need to be heated, so that the temperature of the space where people are located rises rapidly. Fuel air heaters have been widely used in recent years. However, when fuel is burned, it is inevitable to produce waste gases such as carbon monoxide. If a relatively closed space is heated by a fuel air heater, once carbon monoxide leaks, the carbon monoxide concentration in the closed space exceeds a certain range, which will cause carbon monoxide poisoning to people, and even death in severe cases.

[0004] Therefore, those skilled in the art provide a fuel-air heating device linked to carbon monoxide detection to solve the problems raised in the above-mentioned background technology. Utility Model Content

[0005] The utility model aims to provide a fuel air heating device linked to carbon monoxide detection to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A fuel air heating device linked to carbon monoxide detection comprises a fuel air heater, a fuel pump, a starting battery, a control panel, a carbon monoxide detection controller and a fuse for overcurrent protection, the fuel air heater is electrically connected to the starting battery through the fuse to obtain the starting power of the fuel air heater, the control panel is electrically connected to the fuel air heater through a connecting harness, and the control panel is electrically connected to the starting battery through the fuse to obtain the working power of the control panel;

[0008] The carbon monoxide detection controller includes a power conversion module, a carbon monoxide sensor module, a data processing control module, and a relay. The power conversion module is electrically connected to the carbon monoxide sensor module and the data processing control module, respectively. The data processing control module is electrically connected to the carbon monoxide sensor module and the relay, respectively. The power conversion module leads to Pin1 and Pin2 terminals. The power conversion module is electrically connected to the starting battery through Pin1, Pin2 and a fuse. The relay has a normally open contact, a normally closed contact and a common contact. The normally closed contact leads to Pin3, and the common contact leads to Pin4.

[0009] The power conversion module obtains working power from the starting battery through Pin1 and Pin2, and converts it into the voltage required by the carbon monoxide sensor module and the data processing control module for power supply; the carbon monoxide sensor module can detect the concentration value of carbon monoxide from the air, and output a voltage value that changes with the concentration value of carbon monoxide to the data processing control module, and the data processing control module receives the voltage value to obtain the concentration value of carbon monoxide in the air; the data processing control module can output voltage to control the relay, and the data processing control module can set the carbon monoxide concentration threshold. When the carbon monoxide concentration threshold reaches the set value, the data processing control module outputs voltage to the coil of the relay.

[0010] Furthermore, the fuel air heater has an output oil pump power positive interface and an oil pump power negative interface, wherein the oil pump power negative interface is electrically connected to the oil pump to provide a negative working power supply to the oil pump, and the oil pump power positive interface is electrically connected to the Pin3 end of the relay, and the Pin4 end of the relay is electrically connected to the oil pump to provide a positive working power supply to the oil pump.

[0011] Furthermore, under normal circumstances, the data processing control module does not output voltage to the relay, the normally closed contact and the common contact of the relay are connected and conducted, the Pin3 terminal and the Pin4 terminal are in a connected and conducted state, the fuel air heater and the oil pump are normally conducted, and the oil pump can work normally; when the data processing control module outputs voltage to the coil of the relay, the common contact and the normally closed contact of the relay are disconnected, the Pin3 terminal and the Pin4 terminal are in a disconnected state, the fuel air heater and the oil pump are disconnected, and the oil pump does not work.

[0012] The utility model detects the carbon monoxide concentration through the carbon monoxide sensor module. When the carbon monoxide concentration reaches a preset threshold, the data processing control module outputs a voltage control relay, thereby cutting off the power supply to the oil pump, thereby cutting off the fuel supply, and the fuel air heating device stops working. In this way, when the carbon monoxide concentration reaches a preset threshold, the oil pump can be stopped quickly and reliably, thereby making the fuel air heater unable to work normally, ensuring the safety of people in the space and improving the reliability and safety of the fuel air heater.

[0016] See also Figure 1-Figure 2 , a fuel air heating device linked to carbon monoxide detection, comprising a fuel air heater 1, an oil pump 5, a starting battery 4, a control panel 3, a carbon monoxide detection controller 2 and a fuse 6 for overcurrent protection, the fuel air heater 1 is electrically connected to the starting battery 4 through the fuse 6, for obtaining a starting power supply of the fuel air heater 1, the control panel 3 is electrically connected to the fuel air heater 1 through a connecting harness, and the control panel 3 is electrically connected to the starting battery 4 through the fuse 6, for obtaining a working power supply of the control panel 3;

[0017] The carbon monoxide detection controller 2 includes a power conversion module 7, a carbon monoxide sensor module 8, a data processing control module 9, and a relay 10. The power conversion module 7 is electrically connected to the carbon monoxide sensor module 8 and the data processing control module 9, respectively. The data processing control module 9 is electrically connected to the carbon monoxide sensor module 8 and the relay 10, respectively. The power conversion module 7 leads to Pin1 and Pin2 terminals. The power conversion module 7 is electrically connected to the starting battery 4 through the Pin1 terminal, the Pin2 terminal and the fuse 6. The relay 10 has a normally open contact, a normally closed contact and a common contact. The normally closed contact leads to a Pin3 terminal, and the common contact leads to a Pin4 terminal.

[0018] In the above technical solution, the power conversion module 7 obtains the working power from the starting battery 4 through the Pin1 and Pin2 terminals, and converts it into the voltage required by the carbon monoxide sensor module 8 and the data processing control module 9 for power supply; the carbon monoxide sensor module 8 can detect the carbon monoxide concentration value in the fuel air heater 1 in real time, and outputs a voltage value that changes with the carbon monoxide concentration value to the data processing control module 9, and the data processing control module 9 receives the voltage value to obtain the concentration of carbon monoxide in the air; the data processing control module 9 can output a voltage to control the relay 10, and the data processing control module 9 can set a carbon monoxide concentration threshold. When the carbon monoxide concentration threshold reaches the set value, the data processing control module 9 outputs a voltage to the coil of the relay 10, cuts off the power supply of the oil pump 5, thereby cutting off the fuel supply, and the fuel air heater 1 stops working. In this way, the fuel air heater 1 can be stopped quickly and reliably when the carbon monoxide concentration reaches the preset threshold, ensuring the safety of people in the space.

[0019] Among them, the fuel air heater 1 has an output oil pump power positive interface and an oil pump power negative interface, wherein the oil pump power negative interface is electrically connected to the oil pump 5 to provide the oil pump 5 with a negative working power supply, and the oil pump power positive interface is electrically connected to the Pin3 end of the relay 10, and the Pin4 end of the relay 10 is electrically connected to the oil pump 5 to provide the oil pump with a positive working power supply.

[0020] Among them, under normal circumstances, the data processing control module 9 does not output voltage to the relay 10, the normally closed contact and the common contact of the relay 10 are connected and conducted, the Pin3 terminal and the Pin4 terminal are in a connected and conducted state, the fuel air heater 1 and the oil pump 5 are normally connected, and the oil pump 5 can work normally. When the carbon monoxide sensor module 8 detects that the carbon monoxide concentration value exceeds the preset value, the data processing control module 9 outputs voltage to the coil of the relay 10, the common contact and the normally closed contact of the relay 10 are disconnected, the Pin3 terminal and the Pin4 terminal are in a disconnected state, the fuel air heater 1 and the oil pump 5 are disconnected, the oil pump 5 does not work, and the fuel air heater 1 does not work.

[0021] In this embodiment, the fuel air heater 1 is used to burn fuel to generate heat, the oil pump 5 is used to draw fuel from the fuel tank, the starting battery 4 is used to ignite the fuel air heater 1, the control panel 3 is used to adjust the temperature and start and stop control of the fuel air heater 1, the carbon monoxide detection controller 2 is used to detect and control the carbon monoxide concentration, and the fuse 6 is used to provide overcurrent protection. The power conversion module 7 inside the carbon monoxide detection controller 2 converts the input voltage into the carbon monoxide sensor module 8. The carbon monoxide sensor module 8 detects the carbon monoxide concentration in the air and outputs the corresponding electrical signal to the data processing control module 9 according to different concentration values. After receiving the electrical signal from the carbon monoxide sensor module 8, the data processing control module 9 determines the carbon monoxide concentration threshold. Once the carbon monoxide concentration reaches a preset threshold, the output voltage control relay 10 cuts off the power supply of the external oil pump 5, thereby cutting off the fuel supply, and the fuel air heater cannot work normally. In this way, the oil pump can be stopped quickly and reliably when the carbon monoxide concentration reaches the preset threshold, thereby making the fuel air heater 1 unable to work normally, thereby ensuring the safety of people in the space.

[0022] The working principle of the utility model is:

[0023] 1) Working status when carbon monoxide concentration is normal

[0024] The carbon monoxide sensor module 8 in the carbon monoxide detection controller 2 outputs the detected carbon monoxide concentration value to the data processing control module 9 through voltage. If the data processing control module 9 determines that the carbon monoxide concentration in the air does not reach the set threshold, it will not output voltage to the coil of the relay 10. At this time, the normally closed contact and the common contact of the relay 10 are connected and conducted, and the Pin3 terminal and the Pin4 terminal are in a connected and conducted state;

[0025] The negative interface of the oil pump power supply of the fuel air heater 1 is electrically connected to the oil pump 5, and the positive interface of the oil pump power supply is electrically connected to the Pin3 terminal, and then connected to the Pin4 terminal through the normally closed contact and common contact of the relay 10, and then electrically connected to the oil pump 5 through the Pin4 terminal, so that the positive interface of the oil pump power supply of the fuel air heater 1 and the oil pump 5 can be electrically conducted, and the oil pump 5 can work normally with the working power provided by the fuel air heater 1.

[0026] When the fuel air heater 1 is started through the control panel 3, since the oil pump 5 can work normally at this time, the fuel air heater 1 can burn the fuel normally and generate heat, and the entire system is in a normal working state.

[0027] 2) Working status when carbon monoxide concentration exceeds the set threshold

[0028] The carbon monoxide sensor module 8 in the carbon monoxide detection controller 2 outputs the detected carbon monoxide concentration value to the data processing control module 9 through voltage. The data processing control module 9 determines that the carbon monoxide concentration in the air reaches the set threshold value, and then outputs voltage to the coil of the relay 10. At this time, the normally open contact and the common contact of the relay 10 are connected, while the normally closed contact and the common contact are disconnected, and the Pin3 terminal and the Pin4 terminal are in a disconnected state;

[0029] Since the positive power interface of the fuel pump of the fuel air heater 1 is disconnected between Pin3 and Pin4, the positive power interface of the fuel pump of the fuel air heater 1 cannot be electrically connected to the fuel pump 5. At this time, the fuel pump 5 cannot work and can no longer supply fuel to the fuel air heater 1. At this time, the fuel air heater 1 cannot work normally due to lack of fuel, and the entire system stops working.

[0030] Since the oil pumping has stopped, fuel combustion is no longer carried out and thus no carbon monoxide is produced, which effectively and reliably prevents the personnel in the space from carbon monoxide poisoning and ensures their personal safety.
