- the neck extends along a neck axis and has a neck section such that, by moving the neck section along the neck axis from the storage tank towards the neck, the neck section has a surface which decreases then increases; this makes it easier to fill the device while limiting the surface exposed to the sun, which limits the rise in temperature of the device;
- the device comprises a cover for closing the device, through which is formed an opening, the sensing element comprising a float configured to float in the filling liquid of the irrigation device, and in which the interface element includes a stem bonded to the float, the stem being configured to extend through the lid opening regardless of the position of the float in the irrigation device;
- the stem has indicia regarding the amount of liquid available in the device; this allows the user to know what volume of liquid is present in the device;
- the device comprises acquisition means cooperating with the liquid level detection device in order to measure the level of liquid in the device; this makes it possible to automatically measure the volume of liquid in the device;
- the device comprises acquisition means capable of measuring the temperature of the liquid in the device; this makes it possible to estimate the rate of evaporation in the device;
- the device comprises transmission means able to communicate information coming from the acquisition means to a terminal equipped with a processor and a memory, for example a telephone terminal; this allows liquid level and temperature information to be communicated to a remote control station.
- the invention proposes a monitoring device configured to cooperate with an irrigation device according to the invention, the monitoring device comprising: a temperature probe able to measure a liquid temperature; an optical acquisition means capable of acquiring information characterizing a level of liquid in the device; transmission means capable of communicating the information recorded to a terminal equipped with a processor and a memory.

- FIG. 1 is a schematic representation illustrating an irrigation device according to the prior art
- FIG. 2 is a schematic representation of an embodiment of the invention
- FIG. 3 is a schematic representation of another embodiment of the invention.
- FIG. 4 is a schematic representation of a monitoring device according to one aspect of the invention. Detailed description of one or more embodiments
- the invention relates to an irrigation device 1 configured to be at least partially buried, comprising a container 2 configured to contain a liquid, a cover 3 intended to close the container 2, and a liquid level detection device 4, comprising a liquid level detection element 5 located in the container 2, and an interface element 6 configured to communicate the liquid level information.
- the container comprises a wall formed of a material permeable to gases and having a permeability to liquids corresponding to a surface flow rate of between 0.1 mL per cm 2 per day and 1 mL per cm 2 per day, under normal conditions of use. Normal conditions of use mean a temperature of 25°C and a pressure equivalent to atmospheric pressure.
- Such a device makes it possible, thanks to an increased exchange surface and the low permeability to the liquid of the container, to greatly increase the irrigation flow rate of the device.
- the absence of the need to completely bury the device is also an advantage because it greatly facilitates installation.
- the irrigation device 1 comprises a jar made of microporous terracotta, which makes it possible to limit the manufacturing cost of the device, and has a geometry comprising a storage tank 8 of substantially spherical shape, an insulation neck 9 extending from the storage tank 8 along a neck axis X, and a neck 10 located at the end of the neck 9, the neck 10 being configured to cooperate with the cover 3

This facilitates the filling of the device by a user, and also limits the phenomena of convective exchange between the surface of the liquid in the storage tank 8 and the air at the level of the neck 10. Indeed, the masses of hottest air are thus concentrated towards the neck 10, and the reduction in section caused by the bottleneck 9 limits the circulation of these masses of air towards the storage tank 8, which limits the quantity of hot air in contact with the liquid. This makes it possible to limit the heating of the liquid in the storage tank 8, which limits evaporation and improves the autonomy of the irrigation device 1.

- the irrigation device may comprise two internal pipes so as to connect two irrigation devices 1 to a third irrigation device 1, and thus create a network connected by a fluidic link. Thanks to the communicating vase linking the various irrigation devices of the network, it suffices to fill an irrigation device so that the fluid circulates and is distributed in all the irrigation devices 1 of the network, which facilitates filling. This also allows to use only one detection device 4 for the whole network.
- the detection element 5 comprises a float 12 configured to float in the filling liquid of the irrigation device 1
- the interface element 6 comprises a rod 13 linked to the float 12, the rod 13 extending substantially parallel to the bottleneck axis X.
