[0013] The present invention will be further described below with reference to the drawings.

[0014] As Figures 1 to 2 shown, a backpack diesel fire extinguishing blower capable of self-producing fire extinguishing agent according to the present invention includes an electronically controlled injection combustion engine 6 and a blower 2 fixed on the electronically controlled injection combustion engine 6; An exhaust port 201 is connected to the air outlet of the blower 2; A front exhaust pipe 3 is connected between the engine exhaust pipe 602 of the electronically controlled injection combustion engine 6 and the exhaust port 201; the output end of the electronically controlled injection combustion engine 6 is connected to the impeller of the blower 2; A diesel fuel tank is mounted on the electronically controlled combustion engine 6. The electronically controlled combustion engine 6 has no essential difference from the prior art, so it will not be elaborated here. A cracker for cracking diesel into carbon monoxide and hydrogen is installed at the intake end of the electronically controlled combustion engine 6, enabling the diesel engine to burn more fully, and the products after combustion are carbon dioxide and water. After the output end of the electronically controlled combustion engine 6 is connected to the impeller of the blower 2, the electronically controlled combustion engine 6 can drive the impeller of the blower 2 to rotate, and the blower 2 is driven by the electronically controlled combustion engine 6. The carbon dioxide and water generated after the electronically controlled combustion engine 6 burns enter from the front exhaust pipe 3 and are then discharged through the exhaust port 201. The airflow generated by the blower 2 accelerates the carbon dioxide and water at the exhaust port 201 and then directly sprays them to the root of the flame for direct fire extinguishing. The output of the fire extinguisher depends on the diesel fuel provided, and the diesel can be refilled after being used up, improving the fire extinguishing ability of the fire extinguisher. Moreover, the refilling agent for fire extinguishing is the sustainable diesel fuel, reducing the use cost.

The condenser 5 has no essential difference from the prior art, so it will not be elaborated here. The content of carbon dioxide and water in the gas discharged from the condenser 5 is increased, enhancing the fire extinguishing effect. By cooling the gas discharged from the engine exhaust pipe 602 through the condenser 5, the fire extinguishing effect is also improved.

The other end of the second exhaust passage 20102 is connected to an intake pipe 4. The end of the intake pipe 4 is connected to the engine intake pipe 601 of the electronically controlled combustion engine 6. The airflow generated by the blower 2 is discharged from the exhaust port 201 and is divided into two independent airflows that respectively enter the first exhaust passage 20101 and the second exhaust passage 20102. The carbon dioxide and water entering the first exhaust passage 20101 from the front exhaust pipe 3 are directly blown to the root of the flame through the first exhaust passage 20101 for fire extinguishing. A flexible pipe is connected to the first exhaust passage 20101, and a nozzle is provided at the end of the pipe. A person holds the nozzle and directs the ejected carbon dioxide and water towards the root of the flame. The air that enters the second exhaust passage 20102 from the exhaust port 201 enters the engine intake pipe 601 through the intake pipe 4, achieving the effect of boosting the engine intake pressure and increasing the engine power.

[0019] As a preferred embodiment of the present invention, a handle 102 is provided at the top of the back bracket 1; the handle 102 is used to facilitate lifting the entire fire extinguisher by hand.

[0020] As a preferred embodiment of the present invention, the back bracket 1 is a hollow shell structure; a bracket through-hole is provided on one end surface of the back bracket 1 close to the blower 2; the bracket through-hole is provided opposite to the air inlet of the blower 2; a plurality of air inlet grooves 103 are provided on the side surface of the back bracket 1; both the bracket through-hole and the air inlet grooves 103 are communicated with the inner cavity of the back bracket 1; when the blower 2 operates, a negative pressure is generated in the inner cavity of the back bracket 1 through the bracket through-hole, and the air enters the inner cavity of the back bracket 1 from the air inlet grooves 103 and then enters the inner part of the housing of the blower 2 successively through the bracket through-hole and the air inlet of the blower 2; when the air inlet of the blower 2 passes through the back bracket 1, it can take away the heat of the back bracket 1, making the back of a person cooler.
