A folding device for a vehicle flag, which includes a flag, a flagpole, an upper tumbler, a lower tumbler, an elevating mechanism, a locking part, a locking mechanism, and a driving mechanism of the locking part, wherein the flag is fixed on the flagpole, and the flagpole is fixed on the upper tumbler; the lower part of the upper tumbler is rotatably connected to the lower tumbler; the elevating mechanism is arranged between the upper tumbler and the lower tumbler and drives the upper tumbler to rotate to lift and fall; the middle part of the locking part is rotatably connected to the lower tumbler, the rear part of the locking part is connected to the driving mechanism of the locking part; the locking mechanism is arranged between the upper tumbler and the locking part or between the flagpole and the locking part, the driving mechanism of the locking part drives the locking part to rotate upward to lock with the fallen upper tumbler by the locking mechanism. The folding device for thevehicle flag has the advantages that: 1. the flagpole can be folded and can automatically lift and fall, which greatly facilitate installation of the flag; 2. when the flagpole is in the folding andretraction state, driving height of the vehicle is achieved; 3. the retraction state of the flagpole can be locked, thereby preventing the flagpole from being opened under the situation of power off or expire.

The invention belongs to the technical field of electronic atomization, and particularly relates to a flip assembly and an electronic atomizer. The flip assembly comprises a base, a cover body and an elastic piece, wherein the base is provided with a feeding hole; the cover body is provided with a rotating shaft; the base is provided with a sliding groove; the rotating shaft is inserted into the sliding groove; the base is provided with a first clamping part; the cover body is provided with a second clamping part; and when the second clamping part is clamped with the first clamping part, the cover body is in a closed state and can cover the feeding hole. When the feeding hole needs to be opened, the cover body can be directly pushed to enable the second clamping part to be far away from the first clamping part, and at the moment, the elastic piece can push the cover body to flip the cover body so as to enable the cover body to be in an open state, thereby opening the feeding hole. According to the flip assembly, the cover body can be switched between a closed state and an open state without arranging a movable buckle, the situation that the cover body is opened accidentally due to the fact that the movable buckle is touched by mistake can be prevented, leakage is thus avoided, and use safety is improved.
