EXTENSION PIPE AND CIRCULATION TYPE ELECTRIC CLEANER USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an extension pipe to be used for a circulation type electric cleaner easy to use. SOLUTION: This extension pipe is composed of an outer pipe and an inner pipe disposed inside this outer pipe and any one of these outer and inner pipes is formed from plural hollow pipes (first pipe 62 and second pipe 63) formed from a hard material and capable of mutually axially sliding and being adjusted into arbitrary length by a positioning means (operating knob 120). The other pipe is formed from an axially expandable/contractible bellows-shaped hose 67 by fixing the outer peripheral parts of both terminals of the hose 67 and the inner peripheral part of the hollow pipe corresponding to these outer peripheral parts through linking members (ribs 68b and 69b). Thus, the extension pipe is made thin and light in weight easily to use.
