  • Patent number: 11492791
    Abstract: A dosing system and method for dispensing a chemical composition into a tank of a toilet. The system includes a sensor obtaining a parameter representative of an environment of the toilet. The dosing system further includes a non-transitory control unit receiving the parameter and generating an activation signal for triggering dispensing of an amount of the chemical composition into the tank based on the parameter. The system further includes a dosing device inserted inside the tank. The dosing device has a cavity containing the chemical composition and a dispensing mechanism coupled with the cavity. The dispensing mechanism receives the activation signal and dispenses the amount of chemical composition into the tank upon reception of the at least one activation signal.
