Bewässerungseinrichtung für Topfpflanzen

摘要

The present invention relates to an irrigation assembly for potted plants including a housing for containing batteries and a motor therein with a drain hole formed on one side of the housing. A water pump extends from the bottom of the housing to extend into a container for pumping the water into the housing through a water conduit and discharging the water from the drain hole. A water outlet device is connected to the drain hole of the housing through a water discharge pipe. A control circuit PCB has two rotary switches for setting a fixed-humidity mode or a fixed-amount mode and a control circuit for controlling the electrical conduction opportunity of the motor formed thereon. A humidity sensing rod is connected to the housing by electric wires and is formed in a long strip with a plurality of electrode contacts being formed thereon, and being directly inserted into the soil of the potted plants. The moisture inside the soil can be detected by the humidity sensing rod and is compared with the set humidity value, and proceeds timely water supplying when insufficient moisture is detected.
