Abstract
Description
DISPOSITIF D'ARROSAGE AUTOMATIQUE DE PLANTES D'APPARTEMENT
OU D'EXTERIEUR
La présente invention concerne un dispositif d'arrosage de plantes d'appartement ou d'extérieur.DEVICE FOR AUTOMATICALLY WATERING APARTMENT PLANTS
OR OUTSIDE
The present invention relates to a device for watering indoor or outdoor plants.
L'arrosage de plantes d'appartement se fait actuellement, soit manuellement, soit à l'aide de bacs dits à réserve d'eau. Watering of houseplants is currently done, either manually, or using so-called water reserve tanks.
Dans les deux cas, l'arrosage est irrégulier ou incontrôlé.In both cases, the watering is irregular or uncontrolled.
La présente invention a pour objet d'assurer un arrosage optimum en maintenant, en permanence, une humidité constante quelque soit la consommation d'eau absorbée par les plantes ou par évaporation, sans intervention manuelle. The object of the present invention is to ensure optimum watering by maintaining, at all times, constant humidity whatever the consumption of water absorbed by the plants or by evaporation, without manual intervention.
A cet effet, l'invention utilise la variation de llécoulement d'eau à travers un tube élastique susceptible d'être pincé jusqu a obturation complète par un matériau dont les dimensions varient avec l'humidité de la terre à arroser dans laquelle il est placé. To this end, the invention uses the variation of the flow of water through an elastic tube capable of being pinched until completely blocked by a material whose dimensions vary with the humidity of the soil to be watered in which it is placed. .
L'invention sera mieux comprise à la vue des schémas annexés des figures: 1 et 2
En référence à ces dessins, le dispositif comporte un cadre 1 sur lequel est fixé à une extrémité une embase 2 et dont l'autre extrémité est filetée pour laisser passer une vis 3.The invention will be better understood from the diagrams appended to the figures: 1 and 2
With reference to these drawings, the device comprises a frame 1 on which a base 2 is fixed at one end and the other end of which is threaded to allow a screw 3 to pass.
Entre l'embase 1 et la vis 3, le cadre maintient les pièces 4 et 5 en les laissant libres de se déplacer dans un mouvement de translation et en laissant apparente la pièce 4 sur une grande partie de sa surface. La pièce 4 est constituée d'un matériau dont les dimensions varient avec l'humidité, par exemple du bois. La pièce 5 est une butée dont la position dans le cadre 1 est commandée par la vis de réglage 3. Un tube élastique 6, de distribution d'eau passe entre les pièces 4 et 5.Between the base 1 and the screw 3, the frame maintains the parts 4 and 5, leaving them free to move in a translational movement and leaving visible the part 4 over a large part of its surface. The part 4 is made of a material whose dimensions vary with humidity, for example wood. The part 5 is a stop whose position in the frame 1 is controlled by the adjusting screw 3. An elastic tube 6, for distributing water passes between the parts 4 and 5.
En utilisation normale, le dispositif est enfoncé par son embase 2 dans la terre à arroser jusqu'à ce que la pièce 4 soit en contact avec la terre sur la quasi-totalité de sa surface. In normal use, the device is driven by its base 2 into the soil to be watered until the part 4 is in contact with the earth over almost its entire surface.
L'extrémité libre du tube 6 est placé au dessus de la terre à arroser.The free end of the tube 6 is placed above the soil to be watered.
Dans ces conditions, en cas d'excès d'humidité dans la terre la pièce 4 se dilate et écrase le tube 6 jusqu'à son obturation complète, interdisant ainsi tout écoulement d'eau. Dans le cas
contraire, la pièce 4 s'écarte de la pièce 5 en se rétractant et laisse passer l'eau dans le tube 6. Le dispositif fonctionne
donc suivant un asservissement dont l'équilibre ne dépend que de la position de la pièce 5 dans le cadre 1. Cette position, donc le degré d'humidité à l'état d'équilibre, est réglable par une rotation de la vis 3.Under these conditions, in the event of excess moisture in the soil, the part 4 expands and crushes the tube 6 until it is completely closed, thus preventing any flow of water. In the case
on the contrary, the part 4 moves away from the part 5 by retracting and lets the water pass through the tube 6. The device operates
therefore according to a servo whose balance depends only on the position of the part 5 in the frame 1. This position, therefore the degree of humidity in the equilibrium state, is adjustable by a rotation of the screw 3.
Le tube 6 peut être relié à un récipient d'eau 7. The tube 6 can be connected to a container of water 7.
Le récipient 7 peut éventuellement être commun à plusieurs dispositifs. On a alors un réseau de distribution pouvant arroser plusieurs plantes de façon indépendante. The container 7 may possibly be common to several devices. We then have a distribution network that can water several plants independently.
