Abstract

A motor assembly including a motor, a shaft, a gear assembly and an air compressor, encompassed by a vacuum casing and an impeller housing encompassing a number of evenly spaced impellers and impeller casings, the impellers being driven by the shaft of the motor assembly and the air compressor being driven indirectly by the motor through the gear assembly. The motor assembly and the impeller housing and related parts fit in a cylindrical cavity of a body so as to provide suction; high volume, low pressure air compression; and low volume, high pressure air compression. The body has a handle with a light on its front end.

Claims

1. A portable vacuum cleaner/air compressor comprising the combination of:

(a) a body (1);

said body (1) having a substantially cylindrical cavity (13) extending lengthwise therethrough;

said body (1) also having a handle (10) thereon with a light (12) at a front end thereof;

(b) a cylindrical vacuum casing (2) with a first end and a second end;

said first end being open and said second end having an air exit (22) extending therefrom;

said cylindrical vacuum casing (2) being fixed in said cylindrical cavity (13);

(c) at least one impeller (5) being fixed on a shaft (41), an impeller housing (3) which is frictionally secured against an inner wall of said cylindrical cavity (13);

one end of said impeller housing being open and a second end fitting in the open end of said vacuum casing;

said second end of the impeller housing (3) also having vents (31) for exhausting low pressure air therefrom into said vacuum casing (2);

said impeller housing housing (3) having at least one impeller casing (6) therein;

said impeller (5) being encompassed by a respective impeller casing (6);

(d) a motor assembly (4) including a motor (40), said shaft (41), a gear assembly (42) and an air compressor (43) with a high pressure hose (431) connected thereto;

said motor assembly being mounted on the second end of said impeller housing (3) with screws;

said motor (40) driving both said shaft (41) and said gear assembly (42);

said gear assembly (42) driving said air compressor (43); and

(e) an air intake cover (8) with an air intake nozzle (81) extending therethrough;

a filter (7) that fits between a circular plate (71) with a hole in the center thereof and said air intake cover (8);

said air intake cover (8) securing at said open end of said impeller housing (3);

high pressure air from said motor assembly (4) and low pressure exhaust air from said air exit (22) being continuously and simultaneously available whenever said motor (40) is operating.

2. A portable vacuum cleaner/air compressor as claimed in claim 1 further comprising,

said at least one impeller including a plurality of impellers fixed on said shaft (41),

said at least one impeller casing including having a plurality of impeller casings (6);

said multiple impellers (5) being encompassed by respective impeller casings (6).
