[0007] As a further solution of the utility model: a one-way valve that can only exhaust air is installed inside the baffle, and the one-way valve can be opened under the action of high pressure.

[0008] As a further solution of the utility model: the fuel pipe passes through the pressure plate, and the pressure plate can move outside the fuel pipe.

[0009] As a further solution of the utility model: a sealing ring is provided at the connection between the pressure plate and the fuel pipe.

[0010] As a further solution of the utility model: a filter is connected to the inside of the fuel pipe nozzle, and the filter 13 can filter impurities in the fuel. A convex plate is arranged around the inner wall of the fuel pipe nozzle, and both the filter and the convex plate are provided with threaded grooves. The filter is connected to the fuel pipe by bolts.

[0012] As a further solution of the utility model: as described.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The dual-axis motor starts and drives the combustion-supporting air fan to rotate, and the external air is sucked into the casing 1 through the through hole. Then the output end of the cylinder retracts to drive the sealing plate to rotate. After the sealing plate rotates, the ventilation groove is opened, and then the air in the casing is sucked into the space between the baffle and the pressure plate from the ventilation groove. Then, the sealing plate is driven to rotate in the opposite direction through the resetting of the cylinder to close the ventilation groove. At the same time, when the dual-axis motor is started, it will also drive the threaded rod to rotate. The rotation of the threaded rod drives the pressure plate to move. When the pressure plate moves, it compresses the air between the baffle and the pressure plate. After the air is compressed, its volume becomes smaller and the pressure becomes larger to form high pressure. As the pressure plate continues to move, the pressure generated by the air becomes larger and larger, and then the one-way valve is pushed open. Then, the air enters the inside of the fuel chamber from the one-way valve to assist the combustion of the fuel and improve the combustion efficiency.

[0015] 2. Before using the heater, the filter needs to be installed inside the fuel pipe. At this time, the filter is located on one side of the convex plate, and the threaded groove on the filter is on the same straight line as the threaded groove on the convex plate during installation. Then, turning the bolt into the threaded groove will help fix the filter inside the fuel pipe, which is beneficial for filtering impurities in the fuel and improving combustion efficiency.

[0023] In this embodiment: the dual-axis motor 4 is started to drive the combustion-supporting air fan to rotate, and the external air is sucked into the casing 1 through the through hole. Then the output end of the cylinder 8 retracts to drive the sealing plate 10 to rotate. After the sealing plate 10 rotates, the ventilation groove 9 is opened, and then the air sucked into the casing 1 enters between the baffle 6 and the pressure plate 7 from the ventilation groove 9. Then, the sealing plate 10 is driven to rotate in the opposite direction through the resetting of the cylinder 8 to close the ventilation groove 9. At the same time, when the dual-axis motor 4 is started, it will also drive the threaded rod 5 to rotate. The rotation of the threaded rod 5 drives the pressure plate 7 to move. When the pressure plate 7 moves, it compresses the air between the baffle 6 and the pressure plate 7.

At this time, the filter 13 is located on one side of the convex plate 14, and when installed, the thread groove 15 on the filter 13 and the thread groove 15 on the convex plate 14 are located on the same straight line. Then, turning the bolt 16 into the thread groove 15 is conducive to fixing the filter 13 inside the fuel pipe 3, which is conducive to filtering impurities in the fuel and improving the combustion efficiency.

[0026] Working principle: The dual-axis motor 4 starts to drive the combustion air fan to rotate, and the external air is sucked into the casing 1 through the through hole. Then the output end of the cylinder 8 retracts to drive the sealing plate 10 to rotate. After the sealing plate 10 rotates, the ventilation groove 9 is opened, and then the air sucked into the casing 1 enters between the baffle 6 and the pressure plate 7 through the ventilation groove 9. Then, the sealing plate 10 is driven to rotate in the opposite direction through the reset of the cylinder 8 to close the ventilation groove 9. At the same time, when the dual-axis motor 4 is started, it will also drive the threaded rod 5 to rotate. The rotation of the threaded rod 5 drives the pressure plate 7 to move. When the pressure plate 7 moves, it compresses the air between the baffle 6 and the pressure plate 7. After the air is compressed, its volume decreases and its pressure increases, forming a The pressure is high, and as the pressure plate 7 continues to move, the pressure generated by the air becomes larger and larger, and then the one-way valve 11 is pushed open, and then the air enters the combustion chamber 2 from the one-way valve 11 to assist the combustion of the fuel and improve the combustion efficiency. Before the heater is used, the filter 13 needs to be installed inside the fuel pipe 3. At this time, the filter 13 is located on one side of the convex plate 14, and when installed, the threaded groove 15 on the filter 13 and the threaded groove 15 on the convex plate 14 are located on the same straight line. Then, turning the bolt 16 into the threaded groove 15 is conducive to fixing the filter 13 inside the fuel pipe 3, which is conducive to filtering impurities in the fuel and improving the combustion efficiency.
