This utility model discloses a rotary toothbrush head and an electric toothbrush, including a drive unit, a brush head, and a housing. The brush head is located on the side of the top of the housing, and the drive unit is located inside the housing and connected to the brush head. The drive unit moves linearly to drive the brush head to rotate. The drive unit includes a connector, a drive rod, and a first elastic member. One end of the first elastic member abuts against the connector, and the other end abuts against the inside of the housing. The brush head includes a brush disc, and the brush disc has a connecting shaft at one end near the drive rod. Through the cooperation of the connector and the first elastic member, the connector maintains contact with the output part on the electric toothbrush handle under the elastic action of the first elastic member. At the same time, when the connector receives the thrust from the output part on the electric toothbrush handle, the elastic force superimposed by the first elastic member can increase the frequency of reciprocating movement of the connector and the force of each movement, allowing the brush disc to output a higher frequency of rotation and a more stable rotational torque.

The utility model relates to the technical field of production and processing of glass wine bottles, in particular to a paint spraying device for wine bottle bodies, which comprises a rack, a conveying belt, a supporting part, a paint spraying part and a driving part, the conveying belt is arranged on the rack and used for bearing and conveying glass wine bottles, the supporting part is rotatably connected to the conveying belt, and the paint spraying part is arranged on the rack. The rotating center line of the supporting part is perpendicular to the conveying plane of the conveying belt, the supporting part is matched with a bottle opening, a bottle neck and the inner circumferential face of a bottle body of the glass wine bottle in a sliding mode, the supporting part can be used for abutting against the inner circumferential face of the bottle body of the glass wine bottle, and the paint spraying part is arranged on one side of the rack. The paint spraying part is used for spraying paint on the glass wine bottles conveyed to the paint spraying part, and the driving part is used for driving the conveying belt to conduct conveying movement. When the paint spraying device for the wine bottle body is used, labor is saved when a worker inserts a glass wine bottle into the supporting part or pulls the glass wine bottle out of the supporting part.
