Abstract: The present application provides a backflow prevention device, and relates to a backflow prevention technical field. Such a backflow prevention device includes a shell seat, a one-way mechanism and a flow controller. The shell seat is provided with a water channel therein, the one-way mechanism is assembled in the water channel, and the flow controller is assembled in the water channel and located upstream of the one-way mechanism. When the water flows through in a forward direction, the water first passes through the flow controller, and then pushes a movable plug of the one-way mechanism to move forward, so that the water flows forward from a periphery of the movable plug along the water channel and finally passes through a bottom cover of the one-way mechanism.

Abstract: A cold water recycling and reusing apparatus includes a water inlet pipe, a cold water recycling apparatus, a recycling pipe, a cold water return apparatus, a return pipe, a recycling container, and a water outlet terminal. The cold water recycling apparatus is installed at a location near the water outlet terminal. The cold water return apparatus is installed at a location behind the cold water recycling apparatus. The cold water recycling apparatus enables cold water to flow into the recycling container via the recycling pipe. The cold water return apparatus draws the water in the recycling container into the water inlet pipe via the return pipe. The water is adapted to mix with hot water and flows out of the water outlet terminal.

Abstract: A flow control component comprises a water inlet pipe, and a shower equipped with the flow control component. A partition formed with water holes which are different in aperture is disposed in the middle of the water inlet pipe; a first rotating block with a water diversion opening and a main water opening respectively formed at two ends is installed in an inner hole of the water inlet pipe; a first water passage which communicates with the water diversion opening and the main water opening is disposed in the middle of the first rotating block. The water inlet pipe is externally sleeved with an adjusting sleeve; a toggle pin passes through a radial arc-shaped hole on an outside face of the water inlet pipe; the adjusting sleeves drives the first rotating block to rotate through the toggle pin such that the water diversion opening selectively communicates with the water holes.
