Top-bottom water division valve

The utility model discloses a top-bottom water division valve, which comprises a valve body, a valve rod, a moving plate and a fixed plate, wherein the valve rod, the moving plate and the fixed plate are sequentially sleeved in the valve body; a water tank is arranged on the sidewall of the valve body, and the interior and the exterior are communicated through the water tank; the moving plate is arranged on the inner side of the water tank; a water passing groove matched with the water tank is formed in the moving plate; the valve rod and the moving plate are relatively fixed, and have rotating margin relative to the valve body; the fixed plate and the valve body are relatively fixed; through holes and non-through grooves are distributed in the fixed plate; the valve rod and the moving plate rotate relative to the valve body to form at least two states; in a first state, the water tank, the water passing groove, the grooves and an inner passage of the valve rod are sequentially communicated to form a passage, and a passage in the lower side of the valve body is relatively independently closed; in a second state, the water tank, the water passing groove, the through holes and the passage in the lower side of the valve body are sequentially communicated to form a passage, and the inner passage of the valve rod is relatively independently closed. The top-bottom water division valve is more novel and reasonable in structure and favorable for simplifying the inner structural design of a water tap main body and reducing the manufacturing cost of a water tap.
