The invention discloses a method for extracting anthocyanidin from black chokeberries. Azeotropic liquid (an EM reagent for short) of ethyl acetate and methyl alcohol is adopted as an extracting solvent for anthocyanidin in black chokeberries by replacing different ratios of ethanol solutions, both anthocyanidin and anthocyanidin aglycon can be extracted out, and the anthocyanidin extraction rate is increased; meanwhile, when the EM reagent is used as the extracting solvent for anthocyanidin, polarity is appropriate, few impurities with large polarity and few impurities with small polarity are dissolved out, column chromatography isolation and purification are not needed, the anthocyanidin yield is high, and the concentrated extracting solution can be directly subjected to spray drying or vacuum drying to form solid. Accordingly, by means of the method, industrial large-scale production is promoted, meanwhile, the production period is shortened, and the production cost is reduced.

The invention discloses a protective device at an air vent screw part of a heating radiator, which can prevent a screw at the terminal of the heating radiator from being twisted off and facilitate water heating dissipation to guide water and steam. The device disclosed by the invention comprises a U-shaped fixing clamp, a U-shaped push rod, a bag body and a corrugated pipe, wherein the main body of the U-shaped fixing clamp is a combination of two horizontal L-shaped clamping bars; the bottoms of the two horizontal L-shaped clamping bars are respectively provided with a ring-shaped through-hole; the two ring-shaped through-holes are distributed disorderly and are fixed with the lower part of the U-shaped push rod; the distribution of the adjustable ring-shaped through-holes is matched with the width of the heating radiator, and then the U-shaped fixing clamp is fixedly arranged on the heating radiator; the upper part of the U-shaped push rod is formed by a fine adjusting screw and a ball head; two ports of the bag body are both elastic contractive openings, the bag body is wrapped at the tail part of the heating radiator, and an air-bleed hole is wrapped in the bag body; one end of a hose is inlaid inside the bag body, and the other end of the hose faces downwards; and the corrugated pipe is sleeved outside the hose, and a part of the corrugated pipe is fixedly arranged on the U-shaped fixing clamp.

The invention relates to a detachable clothes horse which comprises an umbrella-shaped structure, a supporting rod and a base, wherein the bottom of the umbrella-shaped structure is in plug-in connection with the top of the supporting rod; the bottom of the supporting rod is detachably connected with the base. As all parts of the detachable clothes horse are detachably connected with one another, the detachable clothes horse is convenient to use and store, the occupied area is small, and a plurality of pieces of clothings can be hung on the detachable clothes horse for air-curing at a time; the usage rate of the detachable clothes horse is relatively high.
