Universal dual-cone vacuum hose adapter
View Patent ↗The present device relates to a Universal Dual-Cone Vacuum Hose Adapter suitable for wet or dry applications. This adapter includes a central body made of pliable silicone, ensuring durability and chemical resistance. It features two conical surfaces at opposite ends, each with a unique taper capable of accommodating vacuum hoses and pipes ranging from ¾″ to 2.5″ in diameter. The design includes smaller diameter cylinders at both ends of the central body for aligning with smaller diameter pipes, enhancing attachment stability. Additionally, a center hole runs through the adapter, providing a continuous passageway for fluid or air transfer between the hoses or pipes. This adapter is designed for secure sealing and ease of use, offering improved functionality in various vacuum applications.
1. A universal dual-cone vacuum hose adapter consisting of:
a central body having opposite first and second ends;
a first conical surface formed at the first end and a second conical surface formed at the second end of the central body symmetrical to the first conical surface, each conical surface having a tapered, external diametrical surface configured for sealing engagement with a vacuum hose or piping having a diameter in a range from approximately ¾ inch to 2½ inches;
a first smaller diameter cylinder integrally formed on the first conical surface projecting away from the central body and a second smaller diameter cylinder integrally formed on the second conical surface projecting away from the central body, each cylinder configured to align the adapter with smaller diameter pipes and to enhance the rigidity of the corresponding conical surface;
a center hole formed through the entire length of the adapter to create a continuous passage for fluid or air transfer through the adapter; and,
wherein the central body, the conical surfaces, the smaller diameter cylinders, and center hole are integrally molded as a single piece from a silicone material that is sufficiently transparent to permit visual observation of fluid transfer through the adapter.
