Abstract
A portable beverage brewing device for brewing a single cup or other individual portion of a beverage in an automobile, boat, van, or other vehicle without distracting attention from driving or operating responsibilities. An anchored mounting base, a leveling plate and a clamp together support a coffee maker body in level position. The body includes a water reservoir, a brewing chamber, a drinking cup, and a drip cup or cupholder. A brewing chamber holds a prepackaged filter containing beverage precursor particles. A water reservoir is removable and resealable. A positive displacement pump, driven by a permanent magnet motor pumps water from the water reservoir through an electric heater to the brewing chamber. Operation of the motor and the pump commences only when water has been heated to a predetermined brewing temperature. An encoder counts the number of revolutions of the motor and shuts off the device when a predetermined number of revolutions have been counted and correspondingly a predetermined volume of water corresponding to an individual portion of brewed beverage has been pumped.
