Claim:
An automatic water distributor comprising: a base including a chamber, a first outlet channel connected with an upper end of the chamber, a second outlet channel connected with a lower end of the chamber, and at least one inflow channel communicating with one side of the chamber; between the chamber and the first outlet channel being defined a hole; a valve member including a valve core, the valve core including a plunger portion and a shaft portion extending upward from the plunger portion; the plunger portion moving vertically along the chamber of the base, a top end of the shaft portion inserting into the first outlet channel via the hole, and the valve core also including a first passage fixed therein, the first passage including a spout to spray water downward; a distributing plug retained on the top end of the shaft portion of the valve core and moving vertically with the valve core to disengage upward and open the hole or to move downward to close the hole; a buffer device fixed in the chamber of the valve member and including a second passage to communicate with the spout and the second outlet channel, and including a stop wall disposed thereon and located at a spraying path of the spout, wherein the stop wall keeps a buffer distance from the spout so that after the water sprayed from the spout flushes the stop wall, a watering reaction is forced on the plunger portion of the valve core so that a downward movement of the valve core at a shifting instant is decreased.
