The invention discloses an active valve based on a middle clamped piezoelectric film and application thereof, and belongs to the technical field of fluid control. The active valve comprises a non-piezoelectric actuating structural member and at least one piezoelectric actuating structural member; the non-piezoelectric actuating structural member comprises an outer frame and a supporting component, the outer frame forms a frame of the whole valve, and the supporting component is used for supporting and fixing the piezoelectric actuating structural member; the piezoelectric actuating structural member is used for controlling and forming an air flow / liquid flow channel so as to control the opening and closing of the valve; gaps are formed between the piezoelectric actuating structural members and the outer frames of the non-piezoelectric actuating structural members, or between the piezoelectric actuating structural members when a plurality of piezoelectric actuating structural members exist, or between the piezoelectric actuating structural members and the outer frames and between the piezoelectric actuating structural members at the same time, and the gaps are opened to form air flow / liquid flow channels; the piezoelectric actuating structural member is fixed on the supporting component in a middle fixed support manner; the piezoelectric actuating structural member at least comprises a piezoelectric material, and a piezoelectric film material enables the valve to quickly respond to voltage change.

This utility model discloses a charger cover structure, aiming to provide a charger cover structure that improves assembly efficiency. It includes a charging base bracket; a top cover, with a mounting groove at the upper end of the charging base bracket, the top cover being fitted into the mounting groove; a buckle, connected to the top cover, the buckle including a positioning buckle, a fixing buckle, and a fastening buckle, all of which are engaged with the mounting groove; the positioning buckle is connected to a locking block, the fixing buckle is connected to an anti-disengagement buckle, and the fastening buckle is connected to a reinforcing rib; a screw fixing post, connected to the top cover, the mounting groove having a screw fixing hole; and a charging bracket, the top cover connecting to a limit seat and a second screw fixing post, the other end of the charging bracket having a second screw fixing hole, the top cover having a clearance hole, and the charging bracket connected to a charging spring. The beneficial effects of this utility model are: the charger's structure and assembly are simple and efficient; it facilitates quick positioning and assembly and subsequent disassembly and maintenance; and the assembly method is reliable and stable.

The utility model discloses an optical reflector and a lamp. The optical reflector comprises a wedge-shaped body defined by a first reflecting surface, a third reflecting surface and two second reflecting surfaces, the first reflecting surface and the third reflecting surface are oppositely arranged, and the two second reflecting surfaces are adjacent to the first reflecting surface and the third reflecting surface respectively and are oppositely arranged; the upper bottom surface of the wedge-shaped body is a light source incident port, and the lower bottom surface of the wedge-shaped body is a light outlet; the area of the light outlet is larger than that of the light source incident port; the first reflecting surface, the third reflecting surface and the two second reflecting surfaces are all planes or curved surfaces. According to the technical scheme, the curved surface curvature is high in accuracy, economical efficiency is achieved, and mass production and manufacturing can be achieved; meanwhile, structural assembly is simple, the optical requirement is directly met through a single element, a product and a lamp light-emitting assembly can be directly assembled together, an additional assembling structure is not needed, and cost is greatly saved.
