Referring to fig. 1, the fan heater generally includes an oil tank 1, an electromagnetic pump 3, and a nozzle 7, fuel is supplied from the oil tank 1 to the nozzle 7 through the electromagnetic pump 3 for combustion (for example, patent CN201920549281), and an exhaust oil return line 5 is provided on an oil outlet line 6 between the electromagnetic pump 3 and the nozzle 7, such a system configuration may cause the following problems: when the machine is started, air in the pipeline can be discharged back to the oil tank 1 from the exhaust oil return pipeline 5 under the action of the electromagnetic pump 3, however, the caliber of a nozzle of the nozzle 7 is small, the air in the oil outlet pipeline 6 cannot be completely discharged, when the machine is started, oil supply delay of the electromagnetic pump 3 can be caused due to the air in the oil outlet pipeline 6, ignition difficulty can be caused after the air and the oil are mixed, and after the machine is shut down, fuel oil remained in the oil outlet pipeline 6 cannot be discharged back to the oil tank 1 through the exhaust oil return pipeline 5, so that the problem that the nozzle oil dripping is possibly caused due to fuel oil retention can be caused.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide an oil supply (same as the following) system of a fan heater to solve the problems in the background art.
In order to achieve the purpose, the utility model adopts the following technical scheme:
an oil return system of a fan heater comprises an oil tank, an electromagnetic pump, a nozzle and an electromagnetic valve, wherein an oil outlet of the oil tank is connected with an inlet of the electromagnetic pump through an oil inlet pipe, an outlet of the electromagnetic pump is connected with the nozzle through an oil outlet pipe,
the nozzle seat of the nozzle is connected with an oil return opening of the oil tank through an exhaust oil return pipeline, and the electromagnetic valve is arranged on the exhaust oil return pipeline.
Further, the oil outlet is located at the top of the oil tank, and the oil return port is located at the bottom of the oil tank.
Compared with the prior art, the utility model has the beneficial effects that:
when the electromagnetic pump is started, under the action of the electromagnetic pump, air in the pipeline can be discharged back to the oil tank from the exhaust oil return pipe, and because the inlet outlet of the exhaust oil return pipe is connected to the nozzle seat of the nozzle, the air in the oil inlet pipe and the air in the oil outlet pipe can be discharged into the oil return port of the oil tank through the exhaust oil return pipe, so that the problems that the oil supply of the electromagnetic pump is lagged due to the air in the oil outlet pipe, and the ignition is difficult due to insufficient pressure after the air and the oil are mixed can be solved; after the machine is shut down after use, residual fuel in the oil inlet pipe and the oil outlet pipe can be discharged into an oil return port of the oil tank through the exhaust oil return pipe, so that the fuel cannot be residual in the oil outlet pipe, the problems of fuel retention and possible nozzle oil dripping are avoided.
The foregoing description is only an overview of the technical solutions of the present invention, and in order to make the technical solutions of the present invention more clearly understood and to implement them in accordance with the contents of the description, the following detailed description is given with reference to the preferred embodiments of the present invention and the accompanying drawings. The detailed description of the present invention is given in detail by the following examples and the accompanying drawings.
