Liquid dispensing device

摘要

The liquid dispensing device comprises a dispensing armature (1) for supplying liquid, where the dispensing armature comprises a dispensing direction (5) having a dispensing channel, which ends in a valve-less drain cock with an end-side outlet opening (8). The drain cock is provided with a sterilization device for preventing a recontamination, which has a pair of electrodes that consist of an anode (15) and a cathode (16), which are arranged in the dispenser channel and is connected on a power source. The liquid dispensing device comprises a dispensing armature (1) for supplying liquid, where the dispensing armature comprises a dispensing direction (5) having a dispensing channel, which ends in a valve-less drain cock with an end-side outlet opening (8). The drain cock is provided with a sterilization device for preventing a recontamination, which has a pair of electrodes that consist of an anode (15) and a cathode (16), which are arranged in the dispenser channel and is connected on a power source, where the drain cock is designed in such a way that a residual liquid column remains in a cock section of the drain cock through assembly of the dispenser armature after a dispensing process and flows through the outlet opening. The electrodes are arranged in the area of its cock section in such a way that the oxygen forms itself by the application of power to electrodes at the anode of a part of the residual liquid column, where the dispensing direction comprises a dispensing valve outside the drain cock. A control device is present that is coupled with a sterilization device, where the dispensing valve is electrically actuated. The control device is formed in such a way that the control device is opened by interruption of the current flow between the electrodes around a time. The residual liquid column receives in the dispensing channel by subsequently liquid to an extension in such a way that the both electrodes are wetted. The electrodes are arranged in opposite direction in a row. The cock section of the drain cock has an increasing line section. The cathode is arranged above the anode, which is arranged in the area of the bottom ends and the cathode is arranged at the upper end of the line section. The electrodes in the area of the dispensing channel consist of carbon. The current application of the electrodes is carried out with a voltage of 10-30 V. A current limiting device is provided over which the electrical voltage is adjusted in such a way that the current does not exceed a certain value.
