Hand vacuum with filter indicator

A portable vacuum comprising:

• an inlet housing defining an inlet that is configured to receive dirt, dust and debris therethrough;
• an outlet housing releasably coupled to the inlet housing, the outlet housing defining a handle, an intake, and an exhaust outlet;
• a fan assembly mounted in the outlet housing, the fan being operable for generating an air flow that is exhausted through the exhaust outlet;
• a hose having a first end, which may be selectively coupled to the exhaust outlet, and a second end;
• a set of inflator nozzles, each of the inflator nozzles including a coupling portion, which is configured to selectively engage the second end of the hose, a tapered male connector that defines an outlet aperture, and a relief aperture that extends through a wall of the inflator nozzle into a generally hollow interior;
• and
• a latch for releasably securing the second end of the hose and the coupling portion to one another;
• wherein the tapered male connector of each inflator nozzle is differently sized.

A hand-held portable vacuum comprising:

• an inlet housing defining an inlet that is configured to receive dirt, dust and debris therethrough;
• an outlet housing releasably coupled to the inlet housing, the outlet housing defining a handle, an intake, a fan mount and an outlet, the handle being configured to be grasped by a single hand of a user to permit the user to maneuver the hand-held portable vacuum and orient the inlet into a desired position, the fan mount being disposed between the intake and the outlet;
• a fan assembly mounted in the fan mount and housed by the outlet housing, the fan assembly having a fan inlet and being operable for generating an air flow therethrough;
• a filter disposed between the inlet and the intake and being releasably coupled to one of the inlet housing and the outlet housing;
• a filter indicator coupled to the outlet housing and being in fluid communication with a portion of the outlet housing between the fan inlet and the intake, the filter indicator including a pressure differential indicator that is configured to indicate a pressure differential between air in the portion of the outlet housing and atmospheric air pressure;
• a hose having a first end, which may be selectively coupled to the exhaust outlet, and a second end;
• and
• a set of inflator nozzles, each of the inflator nozzles including a coupling portion, which is configured to selectively engage the second end of the hose, a tapered male connector that defines an outlet aperture, a hollow body portion, which is disposed between the coupling portion and the tapered male connector, and a relief aperture that extends through a wall of the inflator nozzle into a generally hollow interior;
• wherein the tapered male connector of each inflator nozzle is differently sized;
• and
• wherein the relief aperture is formed on a forward face of the hollow body portion, the forward face being oriented relative to the coupling portion such that when the relief aperture is closed by a thumb of a person using the portable vacuum, at least a portion of a force exerted by the thumb to close the relief aperture at least partially urges the inflator nozzle in a direction toward the second end of the hose.
