  • Patent number: 9322593
    Abstract: An umbrella draining assembly mainly includes a cylindrical containing cistern body, a flinging device disposed in an inner section of the containing cistern body, and a bearing plate disposed at a bottom edge of the containing cistern body. A positioning component is disposed in the containing cistern body. The flinging device includes an embedding section, at an inner edge thereof is disposed a plurality of tapering serrated segments. A transmission component is disposed at a bottom edge of the embedding section. When the umbrella draining assembly is in use, a top shaft of an umbrella is inserted into the embedding section, with the positioning component fixing the position of the umbrella. The transmission component drives the embedding section to rotate quickly, causing rainwater on the umbrella to be flung outward due to centrifugal force and to fall on the bearing plate at a bottom edge of the containing cistern body.
