A fluid discharging system having a pump and a discharging spray head having at least one nozzle through which fluid to be discharged exits is provided. The pump has a stator and a rotor which is attached in a chamber of the stator and can be rotated in relation to the stator about a rotational axis and axially along the axis. The axial displacement of the rotor in a first axial direction is configured such that it brings about pump filling operation. A fluid is drawn via an inlet into the stator chamber, and the axial displacement in an opposite second axial direction is configured such that it brings about discharging operation. The fluid in the chamber is expelled out of an outlet of the pump. The outlet of the pump is arranged in the rotor, and the discharging spray head is fluidically connected to the outlet of the pump.

Fluid discharging system

A release device for releasing a flowable preparation includes an electrical energy source, a control unit connected to the energy source, a sensor unit, a release element and an acoustic transducer. The sensor unit is a piezoelectric element suitable for picking up sound waves and/or structure-borne noise from the surrounding environment and converting them into a sensor signal which is converted in the control unit into a control signal for the release element. The release element is the same piezoelectric element and is supplied with electrical signals from the control unit and sprays at least one first preparation from at least one first container. The acoustic transducer is the same piezoelectric element and is supplied with electrical signals from the control unit, which electrical signals are converted by the piezoelectric element into audible acoustic signals in a frequency range of 20 Hz to 20 kHz.

Dispensing device having a piezoelectric element

A method of operating a toilet freshener includes the step of flushing water flow through a toilet bowl within a flushing water period [t-t], in which trepresents the start of flush water flow and tthe end of flush water flow. A sensor unit detects triggering of a flush water stream through the toilet bowl within the flushing water period [t-t] at a time t. A sensor signal, which represents triggering of the flush water stream, is sent to a control unit. The sensor signal is converted, using the control unit, into a control signal for the release element, in response thereto, to release preparation from the container into the interior of the toilet bowl, release of the preparation from the container taking place with a time delay &#x394;t after detection of the flush stream by the sensor unit and continuing for a first preparation release period &#x394;t.

Method for operating a dispenser device in particular a WC rinser

A release device, such as a toilet freshener that releases at least one preparation into the interior of a toilet bowl, comprises a dispenser, at least one container connected to the dispenser for storing at least one preparation, a release element for releasing preparation, a line connecting the release element and the container in communicating manner, a sensor unit capable of detecting vibrations, and a fastening means for detachably fixing the dispenser to the rim of a toilet bowl. In a preferred embodiment, the fastening means rests at least in part on the toilet bowl and is configured to pick up vibrations, such as structure-borne noise, from the toilet bowl and transmit them to the sensor unit.

Dispenser device in particular a WC rinser with fixing means

The application relates to a release device, in particular toilet freshener, for releasing at least one preparation into the interior of a toilet bowl comprising a dispenser, at least one container connected to the dispenser for storing at least one preparation, a release element for releasing preparation, in particular into the interior of a toilet bowl, the release element being connected in communicating manner to the container via a line and the bottom of the container being arranged above the release orifice of the release element in the direction of gravity, such that a difference in level &#x394;h is formed between the bottom of the container and the release orifice of the release element.

A toilet freshener for releasing a preparation into a toilet bowl includes a dispenser, at least one container couplable with the dispenser for storing the preparation, a release element for releasing preparation into the toilet bowl and connected in communicating manner to the container via a line so that the bottom of the container is arranged above the release orifice of the release element in the direction of gravity, such that a difference in level is formed between the bottom of the container and the release orifice of the release element, and a pin connected to the line, which interacts with the couplable container such that, during coupling of the container with the dispenser, the pin displaces a volume of preparation in the container, whereby a pressure is produced in the container, which pressure conveys the preparation over the difference in level into the line.
