[0007] Beneficial effects of the utility model:

[0008] The utility model realizes the effective collection and storage of exhaust gas through the up and down movement of the piston head. When the piston head moves downward, the air in the air cylinder is discharged, and at the same time, the exhaust gas enters the air cylinder from the one-way valve. This design ensures the efficient collection of exhaust gas. After opening the switch valve, the exhaust gas is compressed in the air cylinder by using an air pump to pump air into the air cylinder, thereby realizing the effective compression and storage of the exhaust gas. In this way, more gas can be effectively stored under a certain volume, which is beneficial to subsequent transportation and treatment. BRIEF DESCRIPTION OF THE DRAWINGS
