Dispenser and a control method of the dispenser

A dispenser for a compound-containing container, comprising:

• a dispenser body defining a housing for at least a motor, a main switch, a control unit, a sensor, an indicator, and at least one push rod;
• a replaceable cassette removably attachable to the dispenser body and configured to receive a compound-containing container during dispensing;
• the at least one push rod supported by the dispenser body and mechanically coupled to the motor for displacement relative to the compound-containing container to dispense the compound therefrom;
• the motor disposed within the dispenser body and operatively coupled to the at least one push rod;
• the main switch mounted to the dispenser body and electrically connected to the control unit for actuating the motor;
• the control unit disposed within the dispenser body and comprising a processor and a memory module, the control unit operatively connected to the motor to drive the motor based on actuation of the main switch;
• the sensor configured to detect movement of the at least one push rod and electronically connected to the control unit and configured to generate a movement signal indicative of the displacement of the at least one push rod;
• the indicator mounted to the dispenser body and electrically connected to the control unit, the indicator being configured to receive an alert signal from the control unit;
• wherein the processor of the control unit is configured to execute instructions stored in the memory module to receive the movement signal from the sensor, process the movement signal to determine the displacement of the at least one push rod, calculate a cumulative dispensed volume of compound from a plurality of disposable compound-containing containers received in the cassette, store the cumulative dispensed volume in the memory module, retrieve the cumulative dispensed volume from the memory module for comparison to a predefined threshold corresponding to a replacement condition of the cassette, and, when the predefined threshold is reached, transmit the alert signal to the indicator to provide a user feedback signal to replace the cassette.
