Description

Retractable device for shower nozzle

Technical field

The present invention relates to a kind of retractable device for shower nozzle.

Background technology

The shower nozzle of Xiao Shouing generally comprises shower nozzle and flexible pipe in the market, one end of flexible pipe is connected with feed pipe, the other end of flexible pipe is connected with shower nozzle, outside the flexible pipe of this shower nozzle directly is suspended on, shower nozzle also is to hang on the suspension member of other setting, but there is following defective in this shower nozzle: 1, the flexible pipe of shower nozzle is directly exposed outside, easily the people is tripped; 2, after shower nozzle was suspended on the suspension member, the user runs into shower nozzle easily in the process of bathing fell it, causes shower nozzle to be pounded and hurt sb.'s feelings, and perhaps shower nozzle smashed.

Summary of the invention

Technical problem to be solved by this invention provides a kind of retractable device for shower nozzle, and the flexible pipe of this device can in time be pulled out in use, and flexible pipe can be rolled automatically when stopping using.

For this reason, retractable device for shower nozzle provided by the invention comprises shower nozzle and flexible pipe, one end of flexible pipe is connected with feed pipe, the other end of flexible pipe is connected with shower nozzle, this retractable device for shower nozzle also comprises the volume drawing device, the volume drawing device comprises the volume pull bar, the clockwork spring supporting arrangement, supporting arrangement is provided with water storage, the exit of water storage is provided with clutch shaft bearing, water storage exit phase is liquid sealing to external world, water storage and water inlet pipe conducting, and the end away from clutch shaft bearing on the supporting arrangement is provided with second bearing, volume pull bar rotating support is on the clutch shaft bearing and second bearing, the volume pull bar is connected with clockwork spring, and flexible pipe is wrapped on the volume pull bar, offers water channel in the volume pull bar, one end of water channel and water storage conducting, the other end of water channel is connected with flexible pipe.

Because retractable device for shower nozzle provided by the invention comprises the volume drawing device, when shower nozzle is in idle state, flexible pipe is wrapped on the volume pull bar, the volume pull bar is owing to the tensioner effect that is subjected to clockwork spring can not rotated easily, flexible pipe is pulled out simultaneously when the user overcomes the active force pulling shower nozzle of clockwork spring, the volume pull bar that originally twines flexible pipe this moment rotates, the volume pull bar rotates and again clockwork spring is tightened up simultaneously, the volume pull bar is owing to the tensioner effect that is subjected to clockwork spring is rotated when the user finishes shower and progressively unclamps shower nozzle, the effect that flexible pipe is rolled up pull bar is shunk once more and is wrapped on the volume pull bar, and flexible pipe can be realized by water channel on the volume pull bar and water storage with being connected of water inlet pipe, therefore the flexible pipe of retractable device for shower nozzle provided by the invention can shrink automatically when shower nozzle is idle and be wrapped on the volume pull bar, does not therefore just have the problem that flexible pipe trips the people or shower nozzle drops.
