Outlet connects the concentrated water collecting box 401, and the connection of the backwashing water outlet of pre-filtering component 21, cartridge filter 22 is rushed
Swabbing collecting box 402.Specifically, during the water process for conveying city planting ductwork forms direct drinking, city planting ductwork conveying
Water of the water after 22 filtration treatment of pre-filtering component 21 and cartridge filter enter in filter membrane component 32, and enter filter
Part water in membrane module 32 forms direct drinking and is delivered in clear water tanks 33, be trapped within the ion of the influent side of film, organic matter,
Bacterium, virus etc. form concentrated water with remaining water and from the waste water discharge opening of filter membrane component 32, concentrated water collecting box 401 is collected useless
Water, which is only the hardness of water, turbidity is higher is unsatisfactory for user's domestic water, still, has due to containing organic matter and inorganic salts in concentrated water
Conducive to plant growth, the irrigation that concentrated water can be used for cell plant is collected by concentrated water collecting box 401；And for pre-filtering component
21, the backwashing water generated when cartridge filter 22 is backwashed, it is exceeded due to containing medicament, pH value, it is impossible to be used in plant
Irrigation, can be collected by washing away water collection tank 402, the water washed away in water collection tank 402 can be used in cell public
The flush water of toilet altogether.Potable water equipment in compared with the prior art directly arranges waste water outside, the present embodiment smart water quality
Regulation and control no-negative-pressure water supply equipment can maximumlly utilize water resource, reduce waste, realize environmentally protective.
The utility model also provides a kind of method of supplying water of above-mentioned Intelligent negative pressure-free multichannel sub-prime water work, including routine
Water supply pattern, direct drinking water supply pattern and water quality adjustment water supply pattern；
The routine water supply pattern：The water of primary flow pipe output directly feeds user terminal use.Specifically, conventional water supply mould
Formula is identical as the mode that the non-negative pressure water-supply installation used usually supplies water, that is, utilizes non-negative pressure water-supply installation by city planting ductwork
Water pressurized delivered to every family use.
The direct drinking water supply pattern：The water of primary flow pipe output is successively after pre-filtering component and filter membrane component processing
The direct drinking supply user terminal of acquisition uses.Specifically, non-negative pressure method of water supply module is entered directly by the water that primary flow pipe exports
In processing module of drinking water, water obtains direct drinking after pre-filtering component and filter membrane component processing and is supplied to user.
The water quality adjustment water supply pattern：Under conventional water supply pattern, when the water quality of the first water quality sensor detection does not reach
When mark, the water of primary flow pipe output first passes through after pre-filtering component is filtered processing, then after being pressurizeed by the first water pump through by
First bypass pipe is delivered to primary flow pipe.Specifically, the water in city planting ductwork is influenced by factors such as season, environment, when different
Phase, the water quality in city planting ductwork can be different, and after the deteriorating water quality of city planting ductwork, this will lead to the water quality of the domestic water of user
Decline, higher level is kept in order to ensure the water quality of user's domestic water, to improve user experience, conventional water supply pattern
Under, when the water quality of the first water quality sensor detection is not up to standard, then the part water of primary flow pipe output will pass through direct drinking and handle
Mould pre-filtering component processing in the block, to obtain the water source of higher water quality, then, then by the way that the first bypass pipe will treated
The water of high water quality is delivered to primary flow pipe, the water quality of user's domestic water can be effectively adjusted in this way, so that this implementation
The functional diversities of example Intelligent negative pressure-free multichannel sub-prime water work, versatility are stronger.Wherein, water quality adjustment water supply pattern, tool
Body is：When the water impurity of the first water quality sensor detection is exceeded, the water of primary flow pipe output is filtered by more medium filter
Processing；And/or when the first water quality sensor detection water have peculiar smell it is heterochromatic when, primary flow pipe output water pass through activated carbon mistake
Filter filtration treatment；And/or when the hardness or exceeded content of beary metal of the water of the first water quality sensor detection, primary flow pipe
The water of output passes through water softener filtration treatment.
Further, the method for supplying water further includes energy saving water supply pattern, the energy saving water supply pattern, when user terminal is always used
When water is less than setting value, main feed water pump shuts down, and the water that main water inlet tube introduces is delivered to the first water via the second bypass pipe
Pump, then passed through after being pressurizeed by the first water pump and primary flow pipe is delivered to by the first bypass pipe.Specifically, being transported in non-negative pressure method of water supply module
During row, for main feed water pump in order to provide sufficiently large hydraulic pressure, the power of main feed water pump 12 is larger to cause power consumption larger, but
It is that, in the stage at night, the water consumption of user is seldom, at this point, energy saving water supply pattern starts, main feed water pump shuts down, and utilizes
The water pressurized delivered that the first water pump in direct drinking processing module is introduced main water inlet tube as power is to user terminal, in this way, can
It is real in the case where water consumption is less, to effectively reduce the energy consumption of the present embodiment Intelligent negative pressure-free multichannel sub-prime water work
Existing green low-carbon operation.
Compared with prior art, the advantages of the utility model and good effect is：Intelligence provided by the utility model is without negative
Multichannel sub-prime water work is pressed, mould is handled simultaneously for the domestic water of user and direct drinking by using non-negative pressure method of water supply module
Block supplies water, and non-negative pressure method of water supply module is separately configured without being directed to direct drinking function, this will greatly reduce installation cost and make
With cost, while the occupied space of complete equipment is substantially reduced, meanwhile, using the first water quality sensor in main waterway come
The water quality situation of the water of detection non-negative pressure method of water supply module conveying can pass through part water when detecting that water quality is unsatisfactory for requiring
Primary flow pipe output is again returned to after crossing the processing of pre-filtering component, so as to easily adjust the water quality of user's domestic water,
It realizes Intelligent negative pressure-free multichannel sub-prime water work function diversification, and reduces its occupied space, reduce installation and make
Use cost.
Finally it should be noted that：Above example is only to illustrate the technical solution of the utility model, rather than its limitations；
Although the utility model is described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that：
It still can be with technical scheme described in the above embodiments is modified, or is carried out to which part technical characteristic etc.
With replacement；And these modifications or replacements, various embodiments of the utility model technology that it does not separate the essence of the corresponding technical solution
The spirit and scope of scheme.
