The invention relates to a vehicular continuous packaging garbage can which comprises a main cylinder, a garbage bag storage mechanism, a transmission mechanism, a door opening mechanism, a cutting mechanism, a binding mechanism and sealing mechanisms. The garbage bag storage mechanism comprises an auxiliary cylinder and an upper cover and is used for storing long-cylinder plastic bags without hotcutting, the transmission mechanism is mounted at the bottom of the main cylinder and comprises an outer pedal and an inner pedal, power is transmitted to mechanisms through three groups of steel wire ropes, the binding mechanism and the sealing mechanisms are mounted in the main cylinder according to a set sequence, the cutting mechanism are mounted in the middle of the two sealing mechanisms, the steel wire ropes drive the door opening mechanism, the binding mechanism, the sealing mechanisms and the cutting mechanism to move according to sequences when the pedals are stepped, two sections of a garbage bag are bound, sealed and cut, the lower garbage bag slides out from a garbage can door, the upper garbage bag is sealed and then serves as bottom of next garbage bag packaging, and the mechanisms reset through corresponding spring mechanisms when the pedals are loosened, so that a simple, efficient and continuous garbage packaging function is achieved.
