Toilet flusher having electromechanically induced release of active agent

Abstract

Dosing mechanism for free-flowing preparations, comprising a dosing device having an energy source, a control unit, and a sensor unit, and at least one first tank containing a first preparation and that can be coupled to the dosing device, the dosing device comprising a micropump controllable by the control unit and having a specific delivery rate of less than 500 l/min.

1 . Dosing device comprising:
 a power source,   a control unit,   a sensor unit, and   at least one first container containing a first preparation, wherein the first container is couplable to the dosing device,   wherein the control unit cooperates with the sensor unit and the power source so that when there is a defined sensor signal, the power source acts on a dispensing element and/or pump so that at least the first preparation is dispensed from the first container to the surroundings.   
   
   
       2 . Dosing device according to  claim 1 , wherein the at least one first container is couplable to the pressure side of the pump. 
   
   
       3 . Dosing device according to  claim 1 , wherein the at least one first container is couplable to the intake side of the pump. 
   
   
       4 . Dosing device according to  claim 1  further comprising a valve arranged between the at least one first container and the pump. 
   
   
       5 . Dosing device according to  claim 6 , wherein the valve is actively controllable by the control unit so that a first control signal induces opening of the valve and a second control signal induces closing of the valve. 
   
   
       6 . Dosing device according to  claim 1  further comprising at least one second container containing a second composition, wherein the at least one second container is couplable to a dosing apparatus. 
   
   
       7 . Dosing device according to  claim 6 , wherein the dispensing of the preparation is induced by a first pump couplable to the first container and a second pump couplable to the second container. 
   
   
       8 . Dosing device according to  claim 1 , wherein the at least one first container further comprises an RFID label containing at least information about the contents of the container and is readable by the sensor unit. 
   
   
       9 . Dosing device according to  claim 6 , wherein the dosing apparatus is protected from splash water. 
   
   
       10 . Dosing device according to  claim 6 , wherein the power source, control unit, sensor unit and pump are cast so that the dosing apparatus is waterproof. 
   
   
       11 . Dosing device according to  claim 6 , wherein the dosing apparatus is arranged on the outer edge of the toilet bowl. 
   
   
       12 . Dosing device according to  claim 1 , wherein the control unit ( 4 ) is a programmable microcontroller. 
   
   
       13 . Dosing device according to  claim 13 , wherein a plurality of dosing programs is stored on the microcontroller, these programs being selectable and executable in accordance with the container coupled to the dosing apparatus. 
   
   
       14 . Dosing device according to  claim 6  further comprising a container couplable to the dosing apparatus. 
   
   
       15 . Container according to  claim 14  further comprising an RFID label having at least information about the contents of the container. 
   
   
       16 . Container according to  claim 14  further comprising a pressure-equalizing valve. 
   
   
       17 . Container according to  claim 14  further comprising a nonreturn valve. 
   
   
       18 . Method for controlling the dosing device according to  claim 1  comprising:
 receiving sensor signals containing at least information about the contents of at least one container and/or information representing at least one physical, chemical or mechanical parameter,   comparing the sensor signals with threshold values, and   generating a sensor signal when a condition defined by comparison of the sensor signals with the threshold values is met.   
   
   
       19 . Method for controlling the dosing device according to  claim 18 , wherein the condition defined by comparison of the sensor signals with threshold values for generating a control signal is selected according to the contents of at least one container.
