Claims13
A dosing system comprising:
- a dispensing tube to dispense a viscous liquid from a holding container to an output container, said dispensing tube comprising an upper and a lower valve;
- and
- a peristaltic pump comprising a solenoid with a bobbin coil and a rear magnet, said solenoid having a metal core integrally connected with a piston cap at a first end and a permanent magnet at a second end thereof, said permanent magnet having a magnet attraction to said rear magnet, and a hall effect sensor to measure a strength of a front sensor magnet of said pump and to determine a presence of said dispensing tube;
- said piston cap to push against said dispensing tube when said bobbin coil is charged, causing said viscous liquid to open said lower valve.

A home system for producing a flavored carbonated drink, said home system comprising:
- a carbonation system to carbonate water according to a desired level of carbonation;
- a syrup holder to hold at least one syrup container, each syrup container to contain a syrup;
- an RFID reader to read information about said syrup stored on an RFID tag attached to said at least one syrup container;
- a database to store pre-determined schedules based on said information;
- wherein said information is at least one of:
- attributes of said syrup and an amount of said syrup previously dispensed from said at least one syrup container;
- a pumping system includes a peristaltic pump, one per said at least one syrup container, to pump syrup according to a pre-determined schedule, the peristaltic pump comprising a solenoid with a bobbin coil and a rear magnet, said solenoid having a metal core integrally connected with a piston cap at a first end and a permanent magnet at a second end thereof, said permanent magnet having a magnet attraction to said rear magnet, and a hall effect sensor to measure a strength of a front sensor magnet of said pump and to determine a presence of said dispensing tube;
- wherein said pre-determined schedules are based on said information and a desired strength of drink;
- a drink dispenser to dispense said carbonated water and said syrup into a drinking vessel;
- and
- a controller to receive said desired strength of drink and a selected syrup flavor and to coordinate between said carbonation system, said pumping system and said drink dispenser to dispense the flavored carbonated drink according to said level of carbonation and said selected syrup flavor.
