A cooling pipe 7 is installed at the middle position of the surface of the exhaust pipe 6, which is convenient for cooling the exhausted gas well and avoiding threats to personnel due to excessive temperature.

[0018] In this embodiment: the two ends of the cooling pipe 7 are connected to the liquid storage tank 11 through the water outlet pipe 8 and the return pipe 9 respectively. A water pump 10 is installed at the middle position inside the liquid storage tank 11 through the water outlet pipe 8. The model of the water pump 10 can be MP-15R, so that the overall device has a good air cooling effect.

[0019] In this embodiment: a fixing component 28 is provided at the upper end of the surface of the inlet valve seat 3 and the outlet valve seat 5, a sealing cover 17 is installed on one side of the fixing component 28 through a snap component 29, and a sealing layer 30 is provided inside the sealing cover 17, so that the overall device has good sealing performance to prevent air from entering or flowing out, and a connecting rod 15 is installed at the middle position of the sealing cover 17 through a sealing ring 16.

[0020] In this embodiment, a valve spring 14 is mounted at the middle position of the surface of the connecting rod 15 through a valve spring mounting plate 13, and a mounting hole 31 is provided at one end of the connecting rod 15 to facilitate the installation and use of the structure.

[0021] In this embodiment: limiting nuts 18 and limiting bolts 19 are installed on both sides of the upper end of the surface of the intake valve seat 3 through sealing rings 16, so that the overall device has a limiting function to prevent the internal base 26 from being brought out of the device by the connecting rod 15, an upper sealing port 27 is provided inside the intake valve seat 3 above the limiting nut 18 and the limiting bolt 19, and an air intake net 21 is provided inside the intake valve seat 3 below the limiting nut 18 and the limiting bolt 19, a filter net 20 is installed on the surface of the intake valve seat 3 at one end of the air intake net 21 through a filter net mounting plate 22, a lower sealing port 23 is provided inside the intake valve seat 3 below the air intake net 21, a base 26 is installed at the middle position inside the intake valve seat 3 through the connecting rod 15, air intake holes 24 are provided on both sides of the surface of the base 26, and baffles 25 are installed at both ends of the base 26, which can block the air intake net 21 to enhance the sealing performance.

[0022] In this embodiment: limiting nuts 18 and limiting bolts 19 are installed on both sides of the lower end of the surface of the outlet valve seat 5 through sealing rings 16, so that the overall device has a limiting function to prevent the internal sealing chassis 36 from being brought out of the device by the connecting rod 15, and a sealing chassis 36 is installed at the middle position inside the outlet valve seat 5 below the limiting nuts 18 and the limiting bolts 19, and the upper end of the sealing chassis 36 is connected to the connecting rod 15 through a connecting part 35, so that the overall device has a good sealing effect.

[0023] Beneficial effects of the present invention: The present invention provides the cylinder body 1 with good air intake and exhaust effects through the arrangement of the intake valve seat 3 and the outlet valve seat 5. The base 26 and the sealing chassis 36 are driven to operate by the internal connecting rod 15 of the intake valve seat 3 and the outlet valve seat 5, so that the cylinder body 1 has good sealing performance during air intake and exhaust, and the engine has good safety during use. The filter net 20 on the surface of the intake valve seat 3 is arranged, so that the operation of the intake valve seat 3 has a good air filtering effect. When the cylinder body 1 is inhaling, air is inhaled through the intake net 21 of the intake valve seat 3, and is filtered while inhaling, so as to avoid affecting the operation of the cylinder due to the entry of the object, which is beneficial to the long-term use of the engine. The setting of the limiting bolt 19 makes the overall device have a good fixing function. The base 26 and the sealing chassis 36 connected to one end of the connecting rod 15 can be well fixed inside the inlet valve seat 3 and the outlet valve seat 5 through the limiting nut 18 and the limiting bolt 19, which also facilitates the disassembly and maintenance of the valve seat, saving manpower and material resources. Through the setting of the water tank 11, the cooling pipe 7, the outlet pipe 8 and the return water pipe 9, the overall device has a good cooling effect, which can effectively cool down the other rows of the outlet valve seat 5 to avoid scalding people. Through the setting of the air treatment bin on one side of the outlet valve seat 5, the overall device has a good air purification effect to avoid affecting the air, and the exhaust gas can be uniformly collected and processed.

[0024] Working principle: When in use, check the safety of each part of the device. After installing the connecting rod 15 through the mounting hole 31, when air is needed inside the cylinder body 1, the air is sucked into the inside of the intake valve seat 3 through the intake net 21 through the intake valve seat 3 on the side of the air inlet 2, and enters the inside of the cylinder body 1 through the air inlet hole 24 in the middle of the base 26. The exhaust port 4 is blocked by the sealing chassis 36 of the outlet valve seat 5 to prevent air from flowing out. When the exhaust gas generated inside the cylinder body 1 is discharged, the sealing chassis 36 of the outlet valve seat 5 creates a gap with the exhaust port 4 under the action of the connecting rod 15, so that the exhaust gas inside the cylinder body 1 is discharged and purified through the air treatment chamber 34 when discharged. At the same time of exhaust, the connecting rod 15 inside the intake valve seat 3 drives the base 26 to move, and the baffle 25 on one side of the base 26 blocks the air intake of the intake net 20 to prevent air from entering during exhaust.
