Claim:
1. A plant watering device, comprising: a water-absorbent first body portion, a second body portion having an open chamber therein and connected to a bottom end of the first body portion, and a water supplying tube having a water outflow opening formed between two ends thereof, wherein the water supplying tube is entirely outside of the open chamber and has a middle section containing the water outflow opening passing adjacent a bottom end of the second body portion, wherein the open chamber is in fluid communication with the first body portion above; wherein the second body portion has a conical or bullet-like shape pointing downwards; a water passage hole is formed at the bottom end of the second body portion-adjacent and immediately next to the water outflow opening of the water supplying tube; and a primary water pressure reducing mechanism is provided in the open chamber; whereby a water flow entering one either of the two ends of the water supplying tube will divide at the water outflow opening so that a portion of the water flow is able to flow through the water outflow opening and upwards through the water passage hole into the open chamber and, after the portion of the water flow through the water passage hole passes about the primary water pressure reducing mechanism, an amount of water from the water flow is able to permeate upwards through the first body portion for supplying water to nearby plant and soil; a secondary water pressure reducing mechanism between the open chamber and the bottom end of the first body portion, wherein the secondary water pressure reducing mechanism includes a water-permeable disc disposed at the bottom end of the first body portion.
