Isolating plate for a flowerpot for storing water and supplying water

An isolating plate for a flowerpot for storing water and supplying water with predetermined amount, comprising:

• an isolating plate with vent holes, an auxiliary water storage chamber, and a water control chamber;
• wherein
• the isolating plate has a downward groove seat;
• the groove seat is installed with a spacer having a cover;
• the spacer spaces the groove seat into a water control chamber and a water supply groove;
• the spacer is not tightly sealed so that water in the water control chamber drains into the water supply groove;
• the cover above the spacer seals the opening at an upper end of the water control chamber of the groove seat;
• thereby, the planting earth will not drop into the water control chamber;
• the opening at an upper end of the water supply groove is not sealed so that the planting earth fills into the groove to absorb water in the groove;
• moreover, a lower end of the water control chamber has a water hole;
• a lower end of the water hole is communicated to a water storage space below the isolating plate;
• an upper end of the water hole is assembled with a water control means so that water in the water storage space flows into the water control chamber;
• moreover, the water level is controlled in a proper value by the water control means so that the water level in the water supply groove is controllable within a predetermined value;
• an auxiliary water storage chamber has the water storage space;
• a ventilating tube is installed in the auxiliary water storage chamber at a place not to communicate with the groove seat of the isolating plate;
• an upper end of the ventilating tube is lower than a bottom of the isolating plate and has a gap to the bottom of the isolating plate so that water will not contact the isolating plate;
• thereby, air flows into the space below the bottom of the isolating plate through the ventilating tube.
