Under the pressure of the anti-dumping ball, the first stopper 4 has a downward movement tendency, thereby compressing the elastic reset member 12 located between the first stopper 4 and the cover body 2. In addition, when connected to the first stopper 4, the connecting member 3 and the second stopper 5 also move downward, so that the second stopper 5 moves in a direction away from the cover body 2, thereby forming a certain distance between the second stopper 5 and the cover body 2, thereby making the interior of the box body 1 connected to the circulation hole, and the material located inside the box body 1 can flow to the outside through the circulation hole, so as to be used. When the device topples over, the position of the gravity ball 7 shifts, and the pressure exerted by the gravity ball 7 on the first limit member 4 is cancelled. The first limit member 4 moves in a direction away from the cover body 2 under the reset force of the elastic reset member 12 until the second limit member 5 abuts against the cover body 2.
