Abstract: The present invention provides a lateral draft tube for a water control valve core, which is defined by a through-type groove and upper and lower openings. The through-type groove is sleeved around the shell of the water control valve core. The upper and lower portions have different diameters on the external wall of the draft tube. A ring flange is formed on the upper portion, and a guide ring surface is formed on the lower portion. The ring flange is provided with a sealing ring, and a drainage portion is arranged at the lower end of the draft tube to connect the through-type groove and guide ring surface. The draft tube can be located higher than the water control valve core, such that upward flow of the guide ring surface is not limited by the water control valve core. Thus, the upward flow of the water control valve core improves.

Abstract: The present invention provides a water control valve core with a segmented locking function. The invention includes a valve casing, a brake unit, and a water control element. A bottom plate under the tube portion of the seat of the brake unit is placed within the hold tank of the valve casing. A driven portion penetrates the bottom plate. The fixed valve, free valve and driving seat of the water control element are arranged within the hold tank of the valve casing. An upper locking portion is assembled under the bottom plate of the seat of the brake unit; and a collapsible lower locking unit is individually manufactured and then assembled onto the locating portion at top of the driving seat of the water control element. The lower locking unit could be interlocked with the upper locking portion.

Abstract: The faucet valve structure of two way automatic repositioning function includes a base ring, resilient spring, activating ring, and linking component. The base ring has a protruding block placed thereon. The resilient spring is placed on the base ring, which includes a first and second effector. The activating ring is placed on the resilient spring, which includes a first support that corresponds to the protruding block and a second support that corresponds to the second effector. The linking component is placed on the top end of the rotary base, and it has a crosswise protruding extension. When the user is using the faucet, whether it is on hot water mode or cold water mode, the brake valve shaft can be repositioned to the middle position, so that when the user is turning on the water regardless of warm or cold, it ensures safety from a burn injury.

Abstract: The water separator of the present invention has water inlets arranged onto a side wall, and a through-hole placed centrally at top of the body for insertion of brake valve rod. The coupling swing base is installed at bottom of the brake valve rod. The bottom of the coupling swing base is mated with the rotational valve plate, and the rotational valve plate is fitted with a through-groove that can align with any water outlet on the stationary valve plate and foundation. Flexible snappers are arranged at intervals around the coupling swing base, such that snapping portions are placed at intervals onto the wall of upper space in the body. When the coupling swing base is rotated to a preset angle under the drive of brake valve rod, the positioning effect could be achieved through the mating of flexible snapper and snapping portion.

Abstract: A ceramic valve core has a multi-stage positioning structure. The multi-stage positioning structure includes a first snapper, which can move along with the swaying motion of the brake valve handle of the ceramic valve core, and a second snapper, which is an integrated component positioned correspondingly to the displacement track of the said first snapper. At the corresponding ends of the first snapper and the second snapper, there is a snap ring mated with at least two pin joint ends. The positioning structure also includes a flexible member, which allows the first snapper or second snapper to operate flexibly. The multi-stage positioning structure of the present invention is sturdy because the first snapper is of a combined type and is flexible thanks to the flexible member.
