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.

The present invention discloses a preparation method of a ginsenoside extract for improving mitochondrial function, and the specific steps are: after pre-treatment of fresh ginseng, ultrasound-assisted flash extraction is performed, after centrifugation, an extract is obtained, and after fermentation, purification is performed, and rotary evaporation is performed using a rotary evaporator to obtain a ginsenoside extract. In the present invention, through the mutual cooperation of multiple steps, the biological components in ginseng can be gradually separated and processed, and through fermentation and enzymatic treatment, ginsenoside Rd can be converted into Rd, and ginsenoside Rd can be further converted into rare saponin F2, and finally converted into Rg3 and CK, so that the obtained ginsenoside has more excellent antioxidant and antibacterial effects, so that the application value is higher, and the crude polysaccharide components contained are separated, the purity of ginsenosides in the extract is improved, so that the mitochondrial function improvement of ginsenosides is further improved.

The invention discloses a motor glue filling tool and a motor glue filling method, and relates to the technical field of motor stator machining, the motor glue filling tool comprises a motor placing seat, a limiting unit and an auxiliary unit are installed on the motor placing seat, and a motor assembly and a feeding pipe are installed on the auxiliary unit. The device has the beneficial effects that hot air is conveyed into the air guide hole through the quick plug, heat preservation is carried out on the stand column, the motor isolation sleeve and the motor assembly, temperature loss is reduced, and it is avoided that flowing of glue in the motor assembly is affected by cooling, and meanwhile airflow flowing in the air guide hole drives the rotating shaft, the telescopic mechanism and the hammer head to rotate through the blades; and the vertical column is knocked and vibrated in the rotating process, through knock vibration, overflow of air in glue is accelerated, flowing is accelerated, the motor assembly is evenly filled with the glue, the situation that filling is not in place is avoided, and the glue filling quality and efficiency are improved.

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.
