Description

 Irrigation device and planter

The present invention relates to an irrigation device and a planter. For the irrigation of plants planted in planters, for example, porous clay cones are known, which are connected via a water pipe with a

Water reservoir are connected. Furthermore, spherical water dispensers are known which can be inserted into the plant substrate by means of a hollow substrate spit. About such irrigation facilities is

continuously delivered water to the plant substrate.

Against this background, an object of the present invention is to provide an improved irrigation device. Accordingly, an irrigation device for a planter with a water reservoir can be arranged in or on the planter, a

Pumping device and one connected to the pumping device

Irrigation line for supplying water to planted in the planter plant substrate proposed.

With the help of the pumping device, it is possible, the plant substrate

to moisten according to demand. This is also over a longer

Period optimal water supply of planted plants in the plant substrate possible. Both dehydration and a

Over-watering of the plant substrate is prevented. Furthermore, the water reservoir allows a decentralized, so independent of a house-water connection supply of planted in the planter plants with water. In particular, the irrigation device is in a planter
