[0043] A secondary air guide mechanism is provided on the lower surface of the partition 8; the secondary air guide mechanism includes two secondary air guide boxes 22, and the two secondary air guide boxes 22 are fixedly installed on the lower surface of the partition 8; the two secondary air guide boxes 22 are respectively arranged under the front and rear side mounting seats 25; the two secondary air guide boxes 22 are respectively connected to the interior of the corresponding mounting seats 25; and through holes are opened at the bottom ends of the two secondary air guide boxes 22.

[0046] Furthermore, a top exhaust assembly 6 is fixedly installed at the inner top of the cylinder 1. The top exhaust assembly 6 is semicircular in design. Three exhaust pipes 4 are fixedly installed at positions on the upper surface of the top exhaust assembly 6 corresponding to the activated carbon box 7. The three exhaust pipes 4 are connected to the interior of the activated carbon box 7 at corresponding positions. A motor 5 is fixedly installed at the middle position on the upper surface of the top exhaust assembly 6. The output shaft of the motor 5 rotates and passes through the top exhaust assembly 6. The output shaft of the motor 5 is fixedly connected to the upper surface of the rotating plate 9.

[0047] Working principle: When in use, the oil and gas are introduced into the air inlet 2, the oil and gas are separated from the oil layer through the condenser 3, and then the exhaust gas enters the cylinder 1. Since the through hole at the bottom of the auxiliary air guide box 22 is blocked, the exhaust gas can only pass through the gap between the long plate 21 and the inner wall of the main air box 17, and then enter the interior of the main air box 17, and then filter through the activated carbon box 7 above it;

[0048] When the air intake volume of the air inlet 2 increases and the gas pressure in the cylinder 1 increases, the exhaust gas pushes the long plate 21 to rotate, so that the long plate 21 rotates around the rotating shaft 18. The rotation of the long plate 21 drives the third slider 24 to slide along the return groove of the round-shaped block 20, thereby driving the first sliders 19 on both sides fixed to the round-shaped block 20 to slide upward, and at the same time drives the spring 16 to contract; the first slider 19 slides upward to drive the first support rod 15 to slide upward, and at the same time the first support rod 15 drives the second slider 14 to slide upward along the groove 12, thereby driving The movable top block 13 moves upward, and the top block 13 moves upward to push the second support rod 11 to rotate counterclockwise; at the same time, the return spring on the second support rod 11 contracts; and then the U-shaped rod 10 fixed thereto rotates downward. At this time, the two pistons 23 fixed at the end of the U-shaped rod 10 are separated from the through holes at the bottom of the two auxiliary air guide boxes 22, and the exhaust gas is discharged to the activated carbon box 7 at the top thereof through the two auxiliary air guide boxes 22 for filtration. The intervention of the auxiliary air guide boxes 22 improves the filtration efficiency of the exhaust gas in the cylinder 1 and reduces the pressure in the cylinder 1.

[0049] When the pressure in the cylinder 1 decreases, the spring 16 stretches and then returns to its original state, thereby driving the first slider 19 to move downward; the first slider 19 moves downward and drives the top block 13 to move downward through the second slider and the first support rod, so that the top block 13 no longer acts on the end of the second support rod 11 above, and the second support rod 11 rotates clockwise under the action of the reset spring and resets, thereby driving the two pistons 23 to re-block the bottom through holes of the two auxiliary air guide boxes 22.

[0050] The bottom of the activated carbon box 7 is fixed by cooperating with the mounting seat. When the activated carbon needs to be replaced, the activated carbon box 7 outside the semicircular top exhaust assembly 6 is pulled out, and the rotation angle of the motor 5 is adjusted so that the activated carbon box 7 passes through the position outside the semicircular top exhaust assembly 6 in turn and is replaced.

Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
