The application relates to the technical field of plant extracts, and discloses a forsythia suspense leaf extract and application thereof. The preparation method of the forsythia suspense leaf extract is as follows: (1) forsythia suspense leaves are treated by killing green, drying and crushing, and then sprayed with a sodium hydroxide-ethanol solution and sealed and placed, followed by drying and steam explosion to obtain solid A; (2) solid A is extracted by refluxing with an ethanol solution, and then subjected to solid-liquid separation and concentration to obtain concentrated solution A, anhydrous ethanol and an additive are added into the concentrated solution A, stirred, placed, subjected to solid-liquid separation, concentrated into a paste, and then water is added into the paste, mixed, and concentrated to obtain concentrated solution B; (3) concentrated solution B is placed at room temperature, subjected to solid-liquid separation, and the collected solid is dried to obtain the forsythia suspense leaf extract. The preparation method of the forsythia suspense leaf extract in the application can effectively extract forsythoside in the forsythia suspense leaves, and the content of forsythoside in the extract can reach more than 60%.

This invention discloses an ultrasonic-assisted solid-state water electrolysis online hydrogen production device and method. The device includes a water electrolysis reactor and a water tank, with the reactor fixedly installed in the water tank. The lower part of the reactor is filled with a bed of water electrolysis material. A hydrogen outlet is located at the upper end of the reactor, and a water inlet is located at the lower end. A peristaltic pump is connected to the reactor inlet and is located in the water tank. An ultrasonic transducer is installed on the outer wall or bottom surface of the reactor. By installing an ultrasonic transducer on the outside of the reactor, the high-frequency vibration of the ultrasonic bed during the water electrolysis process effectively reduces the non-uniform water diffusion caused by material agglomeration, adhesion, and byproduct coverage. This allows water to diffuse uniformly to the material surface, resulting in a stable hydrogen production reaction and improving the stability of hydrogen supply. Ultrasonic waves also enhance the thermal conductivity of the water electrolysis material bed, improving the thermal management of the reactor during the water electrolysis process.

This invention discloses a mold for manufacturing lamp shades that facilitates mold opening, relating to the field of lamp shade injection molding technology. The mold includes a concave mold and a convex mold, which are vertically separated. Each mold consists of an outer metal shell and an inner ventilated steel layer, with a cavity between them. The cavities in the concave and convex molds are interconnected. An injection tube is located in the center of the convex mold, positioned above and inside the mold. An air injection pipe is located on one side of the convex mold, with one end connected to an air pump. The air injection pipe is connected to the cavity. An electric heating system and a water cooling system are installed inside the concave and convex molds. By using ventilated steel as the molding cavity, combined with a negative pressure mechanism and a pressure holding mechanism, this invention ensures that the molten plastic fills the entire molding cavity during molding, thereby improving the yield rate of lamp shade production.

The application discloses a V+1 type magnetic steel slot topology structure for driving a motor rotor, relates to the technical field of permanent magnet synchronous motors, and comprises a rotor which is formed by adhering a plurality of rotor punching sheets, and further comprises: a magnetic circuit structure which is arranged at equal angles on the rotor punching sheet and is used for forming a directional fixed magnetic field around the rotor punching sheet; and a heat conduction structure which is arranged at equal angles on the rotor punching sheet and is located on the inner side of the magnetic circuit structure, and is used for accelerating the heat conduction of the heat which is retained in the rotor punching sheet due to centrifugal force when the rotor punching sheet rotates with the motor starting; the heat conduction structure comprises rotor weight-reducing holes which are arranged at equal angles and are opened in the rotor punching sheet, and the inner wall of the rotor weight-reducing hole is fixed with a flow guide plate. The application utilizes the inclined heat dissipation through grooves formed by the rotor weight-reducing holes and the spiral plate structure formed by splicing a plurality of flow guide plates to accelerate the heat dissipation of the heat in the rotor weight-reducing holes.
