Activated carbon canister with increased dust containing capacity

The invention discloses an activated carbon canister with the increased dust containing capacity. The activated carbon canister with the increased dust containing capacity is provided with a canister body (1) and is further provided with a ventilative partition board (2) arranged at a pipe orifice of the canister body (1). The ventilative partition board (2) is arranged at the pipe orifice extending into the canister body (1) and located in the canister body (1). A cavity (3) used for containing dust is formed by the ventilative partition board (2) and the canister body (1) in the canister body (1). Through holes (21) are formed in the ventilative partition board (2). A ventilation pipe (5) is communicated with the interior of the canister body (1) through the ventilative partition board (2). By the adoption of the activated carbon canister with the increased dust containing capacity, the risk of blockage of the carbon canister in the use process is lowered, and the faults that an oil tank is sucked shrunken, abnormal noise is generated, and an oil gauge is not accurate are reduced.
