  • Patent number: 11913459
    Abstract: A fan assembly includes a fan cover. The fan cover is provided with a vane assembly and is fixed by a rotating shaft, which includes blades and magnetic vanes arranged along its outer contour. The coils are evenly arranged along the fan cover. The magnetic rotor blade and the alternating magnetic field generated by the coils can drive the blades to rotate, and the rotation speed can be adjusted by changing the speed of the alternating magnetic field. The coils are fixedly installed in the outer cover of the fan, and the vane assembly is only installed by the rotating shaft, which can easily disassemble from the vane assembly. The structure is simple and has higher reliability. So, it is not easily damaged, and has a longer service life. The fan assembly can be completely waterproof, so that the product can be used in high humidity and even water.

  • Patent number: 10913140
    Abstract: A bicycling multi-tool with a quicklink removal tool is disclosed. The quicklink tool includes a body having a first prong integral with the body and protruding in a first direction, and a first aperture proximate the first prong. The quicklink removal tool also includes a floating prong base having a second prong integral with the floating prong base and protruding in the first direction. The floating prong base includes a second aperture and a sliding face, and is slideably coupled to the body through a bolt passing through both the first aperture and the second aperture. The bolt is threadedly coupled to at least one of the first aperture and the second aperture. The face of the floating prong base is positioned proximate to and facing a sliding surface of the body. Turning the bolt drives the floating prong towards and away from the first prong.
