Description
Technical field
The utility model relates to water purification field, has particularly related to a kind of waterway conversion valve and the water purifier with this waterway conversion valve.
Background technique
Household water filter on market, the water inlet of product links up with tap water, can give water purifier continuous water supply.In these water purifier products, a class is had to be placed on water purifier on kitchen countertop, its water inlet is connected on water tap, namely on water tap, a water-way conversion device is installed, by water pipe, water is imported in the filter core of water purifier again, tap water is filtered, the water purification after filtration otherwise from product water outlet flow out; Otherwise by water pipe, current are got back in conversion equipment exactly, flow out from the water purification mouth of conversion equipment; The water-way conversion device of existing market, generally can out two kinds of water or three kinds of water, namely former water, purify waste water and gondola water faucet water.Be the direction being changed current by the rotatable handle spool of conversion equipment side, realize out different water.Water-way conversion device can being fixed on faucet outlet of effective sealing, but can not bear hydraulic pressure for a long time.The opposite side of waterway converter has water outlet, connects, imported in filter core by tap water by water pipe with water purifier product.Water purifier on kitchen countertop connects the waterway converter used, and just changes the mode of current.Shutoff water tap is only had to close water outlet.When shutoff is purified waste water, when shutoff water tap, because the fire hose draught animals has very long water route (comprising transducer, water pipe, product filter core and water outlet water pipe etc.) to the water outlet of purifying waste water, the overbottom pressure of depositing in water pipe and filter core, so water outlet still has many water to flow out, these are purified waste water and may be wasted, or water clock is on product side, otherwise wait for a period of time and take away water receiving container again, make troubles to use.
If the valve turning off current is located at the water outlet of purifying waste water, this mode can solve the problem of dripping because overbottom pressure produces.Product can pass through any one shutoff current of Water tap or purification mouth of a river valve, or two are turned off to turn off current simultaneously.But when water purification mouth of a river valve turns off, Water tap is opened, and whole product, water pipe and water-way conversion device all can bear hydraulic pressure, and security requirement is higher, adds the hidden danger that product leaks.When allowing product go out to purify waste water or to turn off current, be good at making clear Water tap and purify waste water outlet valve that be close, that is opened, and is difficult to determine, Consumer will go to attempt, and brings very large inconvenience to use.
Summary of the invention
The utility model, for above-mentioned shortcoming, provides a kind of waterway conversion valve and the water purifier with this waterway conversion valve.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
Waterway conversion valve, comprise valve body, valve body be provided with raw water inlet, the inner chamber be communicated with raw water inlet, respectively with the first former water water outlet and the second former water water outlet of inner space, valve body is also provided with and the overflow valve pocket of inner space, the filtered water water intake be communicated with overflow valve pocket and filtered water water outlet, overflow spool is provided with in overflow valve pocket, the lower end of overflow spool is provided with spring, and overflow spool is provided with runner, and runner is for being communicated with filtered water water intake and filtered water water outlet.The water that second former water water outlet flows out flows into waterway conversion valve from filtered water water intake.The lower end of overflow spool is provided with spring, when the upper-end surface of overflow spool is subject to the hydraulic pressure of constantly increase in inner chamber, overflow spool is pressed downward urgent, until filtered water water intake, runner, filtered water water outlet are communicated with, hydraulic pressure in inner chamber keeps constant, and overflow valve element position no longer changes.
