First Claim
Patent Images
1. A cyclonic vacuum cleaner comprising:
- (a) a back pack harness;
(b) an upper casing attached to said harness;
(c) a lower casing releasably mounted on said upper casing;
(d) at least one cyclone having a lower part and an air exit port, said cyclone being mounted with at least said lower part positioned within said lower casing;
(e) an air entry means providing an air flow path from outside said vacuum cleaner to said at least one cyclone;
(f) air exit means providing an air flow path from said at least one cyclone to outside said vacuum cleaner; and
,(g) fan means driven by a motor positioned within said upper casing above said at least one cyclone for generating an air flow which passes through said air entry means, through said at least one cyclone and through said air exit means.

Abstract
A back-pack vacuum cleaner comprises a back-pack harness, an upper casing attached to the harness and a lower casing rotatably mounted on the upper casing. A cyclonic cleaning assembly is mounted within the upper casing such that at least part of the assembly extends into the lower casing. The motor is positioned within the upper casing above the cyclonic cleaning assembly.

16. A cyclonic vacuum cleaner comprises:
-
(a) a back pack harness; (b) an upper casing attached to said harness; (c) a lower casing releasably mounted on said upper casing; (d) first and second coaxially positioned cyclones having a lower part, said second cyclone being mounted within said first cyclone, said second cyclone having a cyclone exit port, said cyclones being mounted with at least said lower part positioned within said lower casing, said coaxial cyclones mounted so that dirt laden air will enter the first outer cyclone and then the second inner cyclone before exiting through said cyclone exit port; (e) an air entry port positioned on said lower casing for supplying dirt laden air tangentially to said outer cyclone to produce cyclonic rotation of said air within said outer cyclone, said port being located near the top of said outer cyclone and adapted to receive a hose assembly; (f) an air exit port provided on said upper casing; and
,(g) fan means driven by a motor positioned within said upper casing above said cyclones for generating an air flow which passes through said air entry port, said outer cyclone, said inner cyclone, said cyclone exit port, past said motor and out said air exit port. - View Dependent Claims (17, 18, 19, 20)
