Abstract: In a faucet main body fast detaching and replacing method and a faucet structure for implementing the same, the method includes the following steps: placing a fast detaching structure on a mesa; and detaching and replacing a faucet bottom seat, that is connected and locked tight to a faucet set main body and the mesa. The faucet main body fast detaching and replacing method is simple, while the faucet structure is compact, as such facilitating fast detaching the faucet main body.

Abstract: A pipe-in-pipe fast installation structure comprises: an outer pipe; a pliable inner pipe, disposed in the outer pipe; a connector, connected to the outer pipe; and a C ring, formed integrally with an end of the connector. Wherein, the pliable inner pipe penetrates through the outer pipe to extend out from the connector, while an end of the pliable inner pipe is fastened into the C ring. The C ring used for fixing the pliable inner pipe is formed integrally with the connector. As such, the pliable inner pipe can be fastened into the C ring of the connector by making use of the radial compressibility of the pliable inner pipe. The inner pipe and the outer pipe are fixed together through using a special design connector. Therefore, the installation structure is simple in structure, low in production cost, and fast in installation.

Abstract: A water purifying faucet not having pull-out function, comprising: a faucet main body, a dual output bend tube, a hot water input tube, a cold water input tube, a cold water output tube, a purified water input tube, a hydraulic converter, a two-input two-output valve seat, a two-input two-output valve core, a water channel tube, a connector, a central bolt, and a press plate. The two-input two-output valve seat is disposed on the faucet main body, with its two water input ports connected respectively to the hot water input tube and the cold water input tube. The water purifying faucet not having pull-out function is novel in design, easy to operate, and is capable of providing three types of water output, in meeting users' requirements effectively.

Abstract: A two-input and two-output valve core structure comprises: a hood-shape outer shell, and a sway plate sleeve, a sway plate, a movable porcelain plate, and a fixed porcelain plate disposed therein. Wherein the hood-shape outer shell is provided with an upper passage port and a lower passage port. The movable porcelain plate includes a detachable upper movable plate and a detachable lower movable porcelain plate. The fixed porcelain plate includes a detachable upper fixed porcelain plate, a detachable lower fixed plate. A middle section of the sway plate is hinged onto the sway plate sleeve, an upper sway head of the sway plate is protruded out of the upper passage port of the hood-shape outer shell, while a lower sway head of the sway plate is extended into an upper opening of the upper movable plate.

Abstract: A water purification core valve includes a shell having a top opening and a bottom opening. A cam bushing, a cam, a movable tile and a stationary tile are mounted inside the shell. A central portion of the cam is pivotally mounted to the cam bushing and a top portion protrudes beyond the top opening of the shell and is connected to a handle. The movable tile has a cam opening formed through the movable tile for the bottom portion of the cam to be inserted therein. Five water paths formed through the stationary tile and the movable tile and are respectively connected with three water inputs and two water outputs. The water purification core valve is operated by pivoting the handle to align the water paths to corresponding water supply, thereby fulfilling control over three ways of water input and two ways of water output.
