Description

`- 2133008 SPECIFICATION
This invention is concerned with the automatic watering of interior or exterior plants or flowers grown in pots, which must be artificially supplied with water by human intervention.
The growing of plants or flowers in pots, as a natural decoration, is extremely spread all over the world. A difficulty in their correct maintenance is the necessity to water them frequently, in order to maintain in the earth a rather constant humidity. The lack or excess of water, may result in damaging or destruction of the plants. The problem becomes more acute when the human intervention is not available for a long period of time.
The idea of the present invention is to overcome this problem by proposing new types of pots for plants and flowers, with automatic watering, able to maintain a constant humidity for long periods of time.
It has to be mentioned that this idea is not new, but this invention presents new solutions based on a new concept.
The present invention proposes a new type of automatic watering pot, suitable especially for cases of very long time of lack of human intervention, using the floating principle. The pot containing the plant or flower is forced to float on water contained in another pot - the basin or reservoir - such that only the bottom of the pot to be emerged in water. In this way the constant humidity in the earth is ensured by the natural absorption of earth. The flower pot is extracting from the basin only as much water as it is necessary to replace the consumption, represented by the natural requirement of the plant and the evaporation of the earth .

2133~û8 In drawings which illustrate the embodiments of the invention:
Fig.1 is an elevation in section of the embodiment of the invention.
Fig.2 is a detail of the embodiment illustrated in fig.1.
Fig.3 is another detail of the embodiment illustrated in fig.1 Fig.4 is another detail of the embodiment illustrated in fig.1 213~0~8 , The embodiment illustrated in fig.1, comprises the pot 1 which is the container of the earth in which the plants or flowers are planted, the reservoir 2 which contains the water, the float 3 which creates sufficient buoyancy to keep the flower pot floating such as only the bottom (1 to 4 cm) is submerged in the water, and one or more floating rings 4, which are added to float in order to adjust the buoyancy when necessary. This floating ring differs from the float 3 only by itsthickness .
The flower pot can have any shape and can be made of any material like plastic, fiberglass, etc., but is better to have the shape shown in fig.2 and it must be provided with some holes at the bottom to permit the passage of the water. The smaller diameter d should match with the interior diameter of the of the float.
The float 3 and the floating ring 4 can be empty inside and made of plastic, fiberglass, etc., or from Styrofoam (hard plastic foam).

The device works as follows:
A plant or flower planted in the pot, sucks water from the earth, according to its kind, size and environmental conditions such as air temperature and humidity. The best watering is obtained when the water is supplied from the bottom of the pot, if it is maintained at a constant low level under the ends of the roots. In this case the earth absorbs only as much water as the plant or flower sucks from it, keeping a perfect constant humidity.
In the present invention, the pot absorbs water fro the basin through the holes provided at the bottom of the pot. The float and the floating rings provide the necessary buoyancy such as the bottom of the pot to submerge in the water only afew centimeters. From time to time may be once a year, a floating ring should beadded to the float, in order to compensate for the growth of the plant.

Claims

1. A device for automatically watering the plants or flowers, said device comprising a pot adopted to retain said plant or flower, said pot having at least one orifice at the bottom thereof, a basin adopted to retain water therein, a float adopted to support the said pot to float on the water in the basin, such as only the bottom few centimeters of the said pot to be submerged in the water.

2. A device as claimed in claim 1 in which the float and the float rings are made of plastic, or any other impermeable material, empty inside to ensure buoyancy, or from plain Styrofoam.
