Patent Searching and Data

Document Type and Number:
WIPO Patent Application WO/2019/148560
Kind Code:
A retractable water pipe, comprising a pipe body, a pipe joint, and a valve joint. The pipe body comprises an inner pipe (1) and an outer pipe (2). The inner pipe (1) is located inside the outer pipe (2). The inner pipe (1) is prepared from an elastic material. The outer pipe (2) is made of an inelastic fabric. The length of the outer pipe (2) is greater than that of the inner pipe (1). One end of the pipe body is provided with the pipe joint, and the other end is provided with the valve joint. The retractable water pipe is fixed on a component such as a faucet by means of the pipe joint, such that high-pressure tap water flows into the inner pipe (1), and when a valve (11) is closed, due to the pressure of the tap water, the inner pipe (1) is deformed and extended, and the diameter of the deformed inner pipe (1) is limited by the outer pipe (2), thereby implementing extension of the retractable water pipe; when the use of the retractable water pipe is completed, the pressure inside the inner pipe (1) disappears, and the inner pipe (1) is contracted, so as to drive the outer pipe (2) to be contracted together, thereby implementing retraction of the retractable water pipe. The retractable water pipe is convenient to use and store.
