ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to flowerpots and, more particularly, to a flowerpot, which automatically supplies water to the soil in the pot body, and automatically carries off excessive amount of rainwater.
2. Description of the Related Art
FIG. 1
shows a flowerpot according to the prior art. This structure of flowerpot comprises a pot body
10
′, the pot body
10
′ having air holes
11
′ in the bottom wall thereof, and a ventilation filter
12
′ mounted in the pot body
10
′ and adapted for carrying soil for raising plants. The ventilation filter
12
′ comprises a bottom center leg
14
′ supported on the-bottom wall of the pot body
10
′, air vents
13
′ for ventilation of air. This structure of flowerpot is still not satisfactory in function. One drawback of this structure of flowerpot is that the pot body
10
′ cannot accumulate water because the air holes
11
′ quickly carries off water from the pot body
10
′. Another drawback of this structure of flowerpot is that the flowerpot has no means to automatically supply water to the soil carried on the ventilation filter
12
′.
SUMMARY OF THE INVENTION
The present invention has been accomplished to provide a flowerpot, which eliminates the aforesaid drawbacks. According to one aspect of the present invention, the flowerpot comprises a pot body having a plurality of upright ventilation tubes adapted for guiding in outside fresh air and guiding out excessive amount of water accumulated in the pot body, a perforated ventilation filter mounted in the pot body above the upright ventilation tubes and adapted for carrying soil for raising plants, the ventilation filter having a perforated hollow center leg supported on the bottom wall of the pot body for the passing of air and water from the pot body into gaps in the soil carried on the ventilation filter. According to another aspect of the present invention, a perforated ventilation tube is embedded in the soil carried on the ventilation filter and connected to one upright ventilation tube of the pot body for guiding air into gaps in the soil.
