Abstract
Abstract The present invention features a suction wand for use in cleaning lint from the lint-screen cavity of clothes dryers. This lint-catching tool is uniquely designed to provide a lint-loosening action in combination with a vacuum action. This dual action eliminates most of the drudgery associated with this particular task. The tool itself has four snap-together portions. The first portion of the tool consists of a collar that attaches to the corrugated conduit or hose of a vacuuming device. The collar has a flared, rounded end that receives a substantially flat, rounded, hollow, flexible, elongated cleaning tube. The peripheral edges of the cleaning tube are designed to be rounded so as to provide for ease of bending, which is a necessary flexibility for accessing hard-to-reach areas within the clothes-dryer cabinet. The third portion of the wand has an intermediate collar that links the elongated cleaning tube with its unique scraping-and-suction nozzle. This scraping-and-suction nozzle has novel inlet windows that are designed to capture the lint as the wand is thrust against lint-laden surfaces within the clothes cabinet. The inlet windows have scraping edges that form narrow inlet areas for the purpose of drawing strong vacuum through the nozzle.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
109 words
A cleaning wand for particular use in removing lint from a clothes-drying machine, comprising: a collar attachment portion an intermediate portion; an elongated, flexible, hollow, generally flat body portion having first and second distal ends, said body portion being attached to said collar at said first distal end and to said intermediate portion at said second distal end; and a nozzle portion attached to said intermediate portion, said nozzle portion having means defining inlet windows on side and front sections thereof, said inlet windows having scraping edges, whereby the lint may be loosened while a vacuum is being applied, thereby providing a dual-action scraping and vacuuming of lint-laden surfaces.
Claim 2
Dependent Claim
109 words
A cleaning wand for particular use in removing lint from a clothes-drying machine, comprising: a collar attachment portion an intermediate portion; an elongated, flexible, hollow, generally flat body portion having first and second distal ends, said body portion being attached to said collar at said first distal end and to said intermediate portion at said second distal end; and a nozzle portion attached to said intermediate portion, said nozzle portion having means defining inlet windows on side and front sections thereof, said inlet windows having scraping edges, whereby the lint may be loosened while a vacuum is being applied, thereby providing a dual-action scraping and vacuuming of lint-laden surfaces.
Claim 3
Dependent Claim
28 words
The cleaning wand in accordance with claim 1, wherein said collar, said intermediate portion, said body portion and said nozzle portion respectively snap together for ease of assembly.
