Abstract
The utility model discloses a kind of showerheads of anti-return phenomenon, including back-flow preventer, shower and handle.When tap is opened manually, hydraulic pressure at water pipe is greater than the hydraulic pressure at pipeline, water at water pipe can get on diaphragm valve top, it is delivered water to from shower from pipeline, when tap is closed, since the hydraulic pressure in water pipe rapidly reduces, diaphragm valve is resetted, it withstands in annular brace portion, negative pressure is generated in pipeline, is drawn back into the water in shower in pipeline, and the water in shower can be sucked since diaphragm valve resets the negative pressure generated, energy Europe makes shower stop dripping outward quickly after closing tap, reduces the backflow phenomenon after closing tap.The utility model has the beneficial effects that (1) structure is simple；(2) easy to process, greatly reduce manpower, material resources；(3) anti-return effect is good.
Description
Technical field
The utility model relates to showerhead field more particularly to a kind of showerheads of anti-return phenomenon.
Background technique
Existing showerhead, shower finishes Guan Shuihou, due to still having water in water storage cavity, effect of these water in gravity
Under still can from spray orifice ooze out drip, until water storage cavity in water stream it is complete or generate enough negative pressure when can just stop.Although
The water water that Guan Shuihou drips still further below is smaller, but water temperature is relatively low, and flowing back into can make one to feel under the weather on the person, especially
It is that can also extend the wiping time in sombre season, is also possible to cause to catch a cold due to extending the wiping time.Therefore, it is necessary to seek
The showerhead of backflow phenomenon can be reduced after looking for a kind of faucet for closing showerhead.
105478260 A of China Patent Publication No. CN, publication date on April 13rd, 2016, a kind of entitled " band diaphragm valve
Showerhead " disclose a kind of showerhead with diaphragm valve, disadvantage is that, structure is complicated, and diaphragm valve processing is multiple
Miscellaneous, diaphragm valve intensity is low.
Utility model content
The purpose of this utility model is to overcome deficiency in the prior art, it is simple to provide a kind of structure, processing side
Just the showerhead of anti-return phenomenon.
To achieve the above object, the utility model uses following technical scheme:
A kind of showerhead of anti-return phenomenon, including back-flow preventer, shower and handle, the back-flow preventer setting
Below handle；The back-flow preventer includes pipeline and diaphragm valve, and the pipe ends penetrate through, and annular branch is equipped in pipeline
Support part；The annular brace portion is arranged in lower end of duct opening；The diaphragm valve is made of elastic material, diaphragm valve lower end surface
It is close to annular brace portion upper surface.The setting of diaphragm valve, can be when opening tap, and the hydraulic pressure at water pipe is greater than at pipeline
Hydraulic pressure, diaphragm valve top can be got on, be delivered water to from shower from pipeline by the water at water pipe, when tap is closed, due to
Hydraulic pressure in water pipe rapidly reduces, and diaphragm valve is resetted, and withstands in annular brace portion, and negative pressure is generated in pipeline, makes in shower
Water be drawn back into pipeline, shower stops outside flowing water.
Preferably, the insides of pipes wall is equipped with groove, the diaphragm valve is equipped with catch flanges, the catch flanges
It is arranged in groove.Guarantee that diaphragm valve can block in pipeline, diaphragm valve will not be ejected pipeline when tap is opened,
So as to cause blocking.
Preferably, the diaphragm valve diameter is greater than annular brace portion internal diameter.Guarantee when tap is closed, diaphragm valve energy
The through-hole of annular brace portion is blocked.
Preferably, the diaphragm valve thickness is between 5mm ~ 10mm.Guarantee that the intensity of diaphragm valve keeps out negative pressure enough, prevents
After sealing faucet is closed, diaphragm valve is inhaled into water pipe.
Preferably, the pipeline lateral wall is equipped with screw thread.Guarantee the connection of water pipe and pipeline.
The utility model has the beneficial effects that (1) structure is simple；(2) easy to process, greatly reduce manpower, material resources；(3)
Anti-return effect is good.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the utility model back-flow preventer structural schematic diagram；
Fig. 3 is the utility model pipeline configuration schematic diagram.
In figure: shower 1, handle 2, back-flow preventer 3, pipeline 31, annular brace portion 311, groove 312, diaphragm valve 32, card
Detain flange 321.
Specific embodiment
The structure of the utility model and working principle are further described in the following with reference to the drawings and specific embodiments:
As shown in Figure 1 to Figure 3, a kind of showerhead of anti-return phenomenon, including back-flow preventer 3, shower 1 and handle 2,
The back-flow preventer 3 is arranged below handle 2；The back-flow preventer 3 includes pipeline 31 and diaphragm valve 32, the pipeline 31
Both ends perforation, and annular brace portion 311 is equipped in pipeline 31；The annular brace portion 311 is arranged at 31 lower ending opening of pipeline；
The diaphragm valve 32 is made of elastic material, and 32 lower end surface of diaphragm valve is close to 311 upper surface of annular brace portion.
31 inner sidewall of pipeline is equipped with groove 312, and the diaphragm valve 32 is equipped with catch flanges 321, and the buckle is convex
Edge 321 is arranged in groove 312.
32 diameter of diaphragm valve is greater than 311 internal diameter of annular brace portion.
32 thickness of diaphragm valve is between 5mm ~ 10mm.
31 lateral wall of pipeline is equipped with screw thread.
In the present embodiment, when tap is opened manually, the hydraulic pressure at water pipe is greater than the hydraulic pressure at pipeline, the water at water pipe
Diaphragm valve top can be got on, be delivered water to from shower from pipeline, when tap is closed, since the hydraulic pressure in water pipe rapidly drops
It is low, diaphragm valve is resetted, is withstood in annular brace portion, negative pressure is generated in pipeline, is drawn back into the water in shower in pipeline,
The water in shower can be sucked since diaphragm valve resets the negative pressure generated, energy Europe make after closing tap shower stop quickly to
It drips outside, reduces the backflow phenomenon after closing tap.The intensity of diaphragm valve guarantees to keep out negative pressure, prevents tap from closing
After closing, diaphragm valve is inhaled into water pipe.Simultaneously between pipeline and diaphragm valve with snap connection guarantee diaphragm valve can be in pipeline
It blocks, diaphragm valve will not be ejected pipeline, so as to cause blocking when tap is opened.
