Problems solved by technology
However, there is no oil return structure between the electromagnetic pump and the oil suction pipe of the fuel heater. Therefore, after the fuel heater is turned off to stop the electromagnetic pump and the wind turbine motor, the fuel remaining in the oil suction pipe enters the combustion barrel for insufficient combustion. And emit black smoke, so its fuel supply is not accurate enough to make the combustion effect not ideal

Embodiment Construction
[0026] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.
[0027] Such as Figures 1 to 2 As shown, the fuel oil heater includes a fuel tank 1 and an outer cover 2 fixedly connected to the fuel tank 1. A combustion tube 3 is fixedly connected inside the outer cover 2. A heat sink 4 is fixedly connected to the front end of the combustion tube 3. The inner end of the combustion tube 3 has The oil and gas inlet 3a is equipped with a fuel injector 5, an ignition needle 6 and a fan 7, and the air outlet of the fan 7 and the fuel injection port of the fuel injector 5 are all facing the oil and gas inlet 3a. The pump 8 and the oil return solenoid valve 9, the oil return solenoid valve 9 has an oil inlet end, an oil outlet end and an oil return end, the oil inlet end of the oil return sol...

The invention provides a fuel oil warm air blower and belongs to the technical field of machines. The fuel oil warm air blower solves the problems that oil supplying of an existing fuel oil warm air blower is not accurate enough and consequently a combustion effect is not ideal. The fuel oil warm air blower comprises an oil tank and an outer cover fixedly connected to the oil tank; a combustion barrel is fixedly connected in the outer cover, and a cooling fin is fixedly connected to the front end of the combustion barrel; the inner end of the combustion barrel is provided with an oil gas inlet, and an oil spraying nozzle, an ignition needle and a draught fan are arranged at the position of the oil gas inlet; an electric fuel oil spraying pump and an oil returning electromagnetic valve arearranged in the oil tank; the oil inflow end of the oil returning electromagnetic valve communicates with the oil outflow end of the electric fuel oil spraying pump through a first oil pipe; the oil outflow end of the oil returning electromagnetic valve can communicate with the oil spraying nozzle through a second oil pipe; the oil returning end of the oil returning electromagnetic valve communicates with the oil tank; and when the electric fuel oil spraying pump stops oil supplying on the oil spraying nozzle, the oil returning end of the oil returning electromagnetic valve is in an open state. An oil supplying pipeline of the fuel oil warm air blower has the backflow function and has the beneficial effects that oil supplying is accurate and work is reliable.
Description
technical field [0001] The invention belongs to the technical field of machinery, and relates to a heater, in particular to a fuel heater. Background technique [0002] The energy-saving and environment-friendly oil heater uses diesel or kerosene as fuel, and generates heat by burning diesel or kerosene. The existing energy-saving and environment-friendly fuel heater pumps the fuel in the fuel tank to the combustion tube of the energy-saving and environment-friendly fuel heater through the gear pump for combustion, but the fuel heater in the prior art uses the gear pump to transport the fuel, and the mist of the fuel The particles are large, and the oxygen supply is less during combustion, so it will cause insufficient combustion. In addition, the heat output effect of the existing fuel oil heater is not very good, and it is easy to generate a large heat loss. [0003] For example, a fuel oil heater disclosed in Chinese patent literature (application number: 201721446144.5)...
