The working principle of the embodiment is as follows: when the storage cylinder 2 is cleaned, after the third electromagnetic valve 27 is opened, when the air pump 3 inflates the air inlet pipe 4, a part of air enters the interior of the piston cylinder 25 through the air conveying pipe 26, and when the air is flushed into the piston cylinder 25, the piston rod 29 moves towards the exterior of the piston cylinder 25, so that the movable rack 14 moves upwards along the inclined plane of the abutting plate 15, so as to drive the connecting gear 10 to rotate forwards, and finally the fixing pipe 11 rotates synchronously, so that the bottom of the buffer pipe 12 can gradually rotate to a vertical downward position, so that the standard oil for cleaning discharged from the storage cylinder 2 can be temporarily stored in the buffer tank 12, otherwise, when the air pump 3 evacuates outwards, the first piston plate 18 descends, and meanwhile, the air in the piston cylinder 25 is also evacuated, the piston rod 29 moves towards the interior of the piston cylinder 25, so that the movable rack 14 slides downwards along the bottom surface of the abutting plate 15, so as to drive the buffer tank 12 to overturn again, so that the bottom of the buffer tank 12 faces upwards, and the standard oil temporarily stored in the buffer tank 12 can be conveniently sucked into the interior of the storage cylinder 2 again.
The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are within the protection scope of the present invention.
