Abstract
A vacuum extraction apparatus comprises a base having a first end and a second end, a tank assembly having a first end and a second end, a fluid pump operable to draw fluid from a first tank of the tank assembly and distribute the fluid to a fluid port, a heating unit operable to control a temperature of the fluid, and one or more vacuum units operable to decrease a pressure level within a second tank of the tank assembly. The second end of the tank assembly is rotatably coupled to the second end of the base, thereby providing access to an internal chamber of the base.
Claims20
A vacuum extraction apparatus, comprising:
- a base having a front side, an opposing rear side, an upper end, and a lower end vertically spaced from the upper end of the base;
- a tank assembly having a front side, an opposing rear side, an upper end, and a lower end vertically spaced from the upper end of the tank assembly, the tank assembly including a first tank defining a first fluid volume and a second tank defining a second fluid volume, wherein the tank assembly is rotatably coupled to the lower end of the base such that the vacuum extraction apparatus is movable between a closed position wherein the front side of the base is in contact with the rear side of the tank assembly and an open position wherein the front side of the base is spaced apart from the rear side of the tank assembly;
- at least two transport wheels coupled to the lower end of the base;
- a fluid pump coupled to the base and operable to draw fluid from the first tank and distribute the fluid to a fluid port;
- and
- one or more vacuum units coupled to the base and operable to decrease a pressure level within the second tank;
- wherein at least a portion of the fluid pump is vertically spaced from the one or more vacuum units within a base chamber when the vacuum extraction apparatus is in a generally vertical operational position;
- wherein both the first tank and the second tank are positioned forward of the front side of the base when the vacuum extraction apparatus is in the generally vertical operational position;
- and
- wherein the first fluid volume of the first tank is positioned above the second fluid volume of the second tank when the vacuum extraction apparatus is in the generally vertical operational position.

A vacuum extraction apparatus, comprising:
- a base having a front side, an opposing rear side, a top side, a bottom side vertically spaced from the top side, and an interior defining a base chamber;
- a tank assembly pivotally coupled to the base with a hinge, the tank assembly including a first tank defining a first fluid volume and a second tank defining a second fluid volume;
- a fluid pump disposed within the base chamber and operable to draw fluid from the first tank and distribute the fluid to a fluid port;
- a heating unit disposed within the base chamber and operable to elevate a temperature of the fluid;
- one or more vacuum units disposed within the base chamber and operable to decrease a pressure level within the second tank, each of the one or more vacuum units including a vacuum motor intake extending from an air intake and providing a closed fluid path to the exterior of the vacuum extraction apparatus;
- and
- an exhaust chamber positioned adjacent to the bottom side of the base and including an exhaust chamber inlet and an exhaust chamber outlet, the exhaust chamber inlet in communication with the base such that during operation of the vacuum extraction apparatus, the exhaust chamber receives exhaust air from the one or more vacuum units and releases the exhaust air through the exhaust chamber outlet;
- wherein, when the vacuum extraction apparatus is in a generally vertical operational position:
- the first tank and the second tank are positioned forward of the front side of the base;
- and
- the first fluid volume of the first tank is positioned above the second fluid volume of the second tank.

A vacuum extraction apparatus, comprising:
- a base having a front side, an opposing rear side, an upper end, and a lower end vertically spaced from the upper end of the base;
- a handle positioned near the upper end of the base and extending away from the rear side of the base;
- a tank assembly pivotally coupled to the lower end of the base such that the vacuum extraction apparatus is movable between a closed position wherein the front side of the base is in contact with a rear side of the tank assembly and an open position wherein the front side of the base is spaced apart from the rear side of the tank assembly, the tank assembly including a first tank defining a first fluid volume and a second tank defining a second fluid volume;
- a fluid pump operable to draw fluid from the first tank and distribute the fluid to a fluid port;
- a heating unit operable to heat the fluid to a selectable temperature, the heating unit including at least a first bi-metal thermostat device for substantially maintaining the fluid at a first temperature and a second bi-metal thermostat device for substantially maintaining the fluid at a second temperature;
- a vacuum system, including a first vacuum unit and a second vacuum unit, the first and second vacuum units configured to be individually or simultaneously operated to provide at least two distinct pressure levels within the second tank;
- an exhaust chamber positioned adjacent to a bottom side of the base and configured to receive exhaust air from the vacuum system;
- a first air intake spaced vertically above the exhaust chamber,
- a second air intake spaced vertically above the exhaust chamber;
- a first vacuum motor intake extending from the first air intake and providing a closed fluid path to the exterior of the vacuum extraction apparatus;
- and
- a second vacuum motor intake extending from the second air intake and providing a closed fluid path to the exterior of the vacuum extraction apparatus;
- wherein, when the vacuum extraction apparatus is in a generally vertical operational position:
- the first tank and the second tank are positioned forward of the front side of the base;
- and
- the first fluid volume of the first tank is positioned above the second fluid volume of the second tank.
