The invention discloses a trash can that can be cooled, comprising: a barrel body, a barrel cover, a pressing plate, a hydraulic pump and a refrigeration plate, the upper surface of the barrel body is partially recessed downwards to form a garbage cavity, and the interior of the barrel body is hollow, and the refrigeration plate is arranged Inside the barrel, the refrigeration plate is fixed on the side wall of the barrel close to the garbage cavity, the lid is hingedly connected to the upper surface of the barrel, and the lid is matched with the barrel so that the lid can cover the barrel When the bung is closed in the opening, the hydraulic pump is fixed on the lower surface of the bung, and the pressure plate is connected to the piston rod on the hydraulic pump, and the piston rod can make the pressure plate move vertically. The garbage can overcomes the problem that the use space inside the garbage can is not fully utilized in the prior art, and when the temperature in the garbage can is very high, the stored garbage is easy to deteriorate and produce an unpleasant smell, which affects the environment at home.
