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 .

,
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.
