As shown in fig. 1, the utility model discloses a pivot 16, 16 both sides of pivot are installed on frame 4, and two outer ends of pivot 16 are fixed with preceding driving lever 6 and back driving lever 7 respectively, have arranged burner 2 and compressor arrangement 3 in proper order between two frames 4, respectively install one set of lever mechanism 1 on frame 4 of both sides.
Referring to fig. 3 to 6, the front shift lever 6, the rear shift lever 7 and the feeler lever 20 on the same side of the combustion device 2 are fixed on the rotating shaft 16, and the piston bar 17 in the combustion device 2 is fixed on the rotating cylinder 18 on the same side. The included angle between the front deflector rod 6 and the rear deflector rod 7 is 29 degrees, and the front deflector rod 6 moves forward 10 degrees along the rotating direction of the rotating cylinder along the radial direction of the piston strip 17 on the rotating cylinder 18 on the same side; the feeler lever 20 is angled at 15 ° to the radial direction of the piston rod 17 on the same side of the drum 18, with the piston rod 17 in front. When the air valve on the air inlet pipe 22 in the combustion device 2 is opened, compressed gas in the air storage tank 15 enters a combustion cavity, the fuel injector 24 also starts to inject fuel, and the fuel injector 24 and the air valve on the air inlet pipe 22 are closed after fuel enters the combustion cavity, so that the combustion cavity forms a relatively closed space. At the moment that the electric spark controller 19 is ignited, the pressure intensity of the combustion chamber is greater than that of the exhaust chamber at the moment that fuel oil in the combustion chamber is combusted, so that the piston bar 17 and the rotary drum 18 in the combustion device 2 are pushed to rotate (the gaps between the two end surfaces of the rotary drum 18 and the two inner end surfaces of the combustion cylinder 21, between the two end surfaces of the piston bar 17 and the two inner end surfaces of the combustion cylinder 21 are 0.3-0.6mm, and between the top surface of the piston bar 17 and the inner surface of the combustion cylinder 21 are 0.3-0.45mm), and gas in the exhaust chamber is exhausted through the. When the rotating shaft 16 rotates, the front shifting lever 6 contacts the roller, the roller 8 is pressed down, the roller 8 rapidly descends to the lowest position, the lever principle shows that the bracket 9 is used as a fulcrum, the roller 8 is used as an outer end point, the lever 10 is used as a lever shaft, the flashboard 13 is used as an inner end point, when the roller 8 descends, the flashboard 13 rapidly ascends through the transmission motion of the lever 10, the collision of a piston strip 17 on a rotary cylinder 18 of the combustion device 2 with the flashboard 13 in the rotating process is avoided, and when the piston strip 17 rotates to the position of the flashboard 13, the front shifting lever 6 is separated from the contact with the roller 8. When the rotating shaft 16 continues to rotate, the contact part of the rear deflector rod 7 and the roller 8 is in a triangular design (triangular wedge structure), the roller 8 quickly rises to the highest position when the rear deflector rod 7 contacts the roller 8, similarly, the roller 8 rises and the flashboard 13 quickly falls to the lowest point due to the lever principle, in the lifting process of the flashboard 13 (the gap between the flashboard 13 and a flashboard groove at the top of the combustion cylinder 21 is 0.3-0.45mm), the tension spring 11 can stabilize the lever 10 and ensure the contact between the flashboard 13 and the rotary drum 18 to prevent air from overflowing, and the gap between the flashboard 13 and the rotary drum 18 when the flashboard 13 contacts at the lowest point is 0.3-0.45 mm. When the rotating shaft 16 continues to rotate to the position where the piston bar 17 is close to the fuel injector 24, the touch rod 20 touches a gas valve switch in the air inlet pipe 22, compressed gas in the gas storage tank 15 enters a combustion cavity, the fuel injector 24 is opened again, and after fuel enters the combustion cavity, the gas valve in the air inlet pipe 22 and the fuel injector 24 are closed, so that a relatively closed space is formed, which is a circulation process of combustion.
As can be seen from fig. 2, 4, 5, and 7, in the compression device 3, the compression chamber gradually decreases and the negative pressure chamber gradually increases as the rotating shaft 16 rotates. The compressed gas in the compression cavity enters the gas storage tank 15 through the one-way valve on the gas outlet pipe 14 along with the rotation of the rotary drum 18 in the compression device 3, wherein the one-way valve is opened when the pressure in the compression cavity is higher than the pressure in the gas storage tank 15, otherwise, the one-way valve is closed. In the process of gradually reducing the compression cavity, the negative pressure cavity is gradually increased and the internal air pressure is lower than the atmospheric pressure, and at the moment, the external air enters the negative pressure cavity through the air suction pipe 12. The rotating shaft 16 continues to rotate, the front deflector rod and the rear deflector rod on the same side of the compression device 3 also rotate along with the rotating shaft, when the front deflector rod 6 contacts the roller 8, the roller 8 is pressed down after the continuous rotation, the roller 8 is quickly lowered to the lowest position, the flashboard 13 quickly rises, the collision between the top surface of the piston strip 17 and the flashboard 13 in the rotating process is avoided (the gap between the top surface of the piston strip 17 and the inner surface of the combustion cylinder 21 is 0.3-0.45mm), and when the piston strip 17 rotates to the position of the flashboard 13, the front deflector rod 6 is separated from the. When the rotating shaft 16 continues to rotate, the rear deflector rod 7 is in contact with the roller 8, so that the roller 8 quickly rises to the highest position, similarly, due to the lever principle, the roller 8 rises, the gate 13 quickly falls to the lowest point, and in the lifting process (the gap between the gate 13 and the gate groove at the top of the compression cylinder 21 is 0.3-0.45mm), the tension spring 11 can stabilize the lever 10 and ensure the contact between the gate 13 and the rotating cylinder 18, so that the air overflow is prevented, and the compression is a cyclic process. The gap between the shutter 13 and the drum 18 at the lowest point is 0.3-0.45mm, and the gap between the two end faces of the drum 18 and the two inner end faces of the compression cylinder 5 is 0.3-0.6 mm.
