Description
Technical field
Water purification product is the utility model is related to, is more specifically a kind of small-sized RO machines with current-stabilizing structure.
Background technology
RO machines are a kind of osmosis filtration methods by international popular, and raw water is pressurizeed, utilizes physical principle mistake
Filter is handled, and is not then added any compound, is produced the pure water machine for being available for the mankind directly to drink（Also referred to as terminal water purification
Equipment）.QB/T4144-2010 requires that water purifier terminal water purification amount need to be more than 0.8L/min.But the product of commercial type,
More than 400G RO machines are because the larger product of net water flux is all without water butt；The flow of conventional 400G RO machines is in 1.05L/min
More than, if to reach bigger terminal water yield, such as 800G specifications, Normal practice is to increase pump output flow and increasing RO films
Area, cause raising up for production unit cost.
The content of the invention
In order to solve the above-mentioned technical problem, the purpose of this utility model is to provide a kind of small-sized RO with current-stabilizing structure
Machine.
The utility model is achieved through the following technical solutions：
A kind of small-sized RO machines with current-stabilizing structure, including for accessing the first order filter core of raw water, the first order filter
The water inlet end of the pump of water side one and RO filter cores of core is connected, and the pure water water side of the RO filter cores is parallel with water butt and gone out
Water water route, third level filter core is provided with the water outlet water route, the third level filter core is connected through a flow-limiting valve with depotition cock
Connect.
In the utility model embodiment, it is unidirectional on the water outlet water route of third level filter core current front end to be additionally provided with one
Valve.
In the utility model embodiment, a pressure air bag is provided with the water butt.
In the utility model embodiment, High-Pressure Water is provided with the water outlet water route between the check valve and third level filter core
Switch, High-Pressure Water switch are connected with pump.
A kind of small-sized RO machines with current-stabilizing structure of the present utility model, have the advantages that：
Terminal net water flux can be increased, in user's acceptable time on the basis of pump and the configuration of RO films is not changed
In the range of, water flow is maintained a stable value range all the time.
Brief description of the drawings
, below will be to institute in embodiment or description of the prior art in order to illustrate more clearly of the technical solution of the utility model
The accompanying drawing needed to use is briefly described, it should be apparent that, drawings in the following description are only more of the present utility model
Embodiment, for those of ordinary skill in the art, on the premise of not paying creative work, can also be attached according to these
Figure obtains other accompanying drawings.
Fig. 1 is schematic diagram of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in inventive embodiments is carried out it is clear,
It is fully described by, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole implementation
Example.Based on embodiment of the present utility model, those of ordinary skill in the art are obtained on the premise of creative work is not made
The every other embodiment obtained, belong to the scope of the utility model protection.
Reference explanation book accompanying drawing, a kind of small-sized RO machines with current-stabilizing structure, including the first order for accessing raw water are filtered
Core 10, the water inlet end of the pump 20 and RO filter cores 30 of water side one of the first order filter core 10 are connected, the RO filter cores 30
Pure water water side is parallel with water butt 40 and water outlet water route, is provided with third level filter core 50 on the water outlet water route, and the described 3rd
Level filter core 50 is connected through a flow-limiting valve 60 with depotition cock 70.
Further, a check valve 80 is additionally provided with the water outlet water route of the current front end of third level filter core 50.
Further, High-Pressure Water switch 81 is provided with the water outlet water route between the check valve and third level filter core, should
High-Pressure Water switch is connected with pump, and High-Pressure Water switch is used for detecting in water butt whether fill water, if filling water,
Pump will be signaled to, pump is stopped.
Further, a pressure air bag 90 is provided with the water butt, the pressure air bag at work, will be located at water storage
Water in bucket is pressed on water outlet water route.
The application is in the other small-sized RO machines of some flux level（Such as 400G) configuration on the basis of increase an external water butt,
Increase a flow restriction in water side.Its principle：Terminal（Depotition cock）During closing, machine, which works on, is stored into water purification
Water butt, the pressure air bag that hydraulic pressure will be extruded in water butt, when the pressure of water butt reaches the boundary of setting（Water butt storage is full
Water）, machine is stopped.When terminal water outlet is opened, machine operation, net water flux is produced, the air bag in water butt is also because letting out
Pressure squeezes out the water in bucket, produces a net water flux, because the flow of water butt can reduce because pressure reduces, at end
Increase a flow restriction before bringing out water（Such as current limliting 1.6L/min, 2L/min）, with regard to can make terminal water outlet reach one it is relatively large
Flow and the effect of constant current.When the pressure of water butt drops to certain, High-Pressure Water switch will send signals to pump, start pump
Work, produce net water flux.
Above disclosed is only preferred embodiment of the present utility model, certainly can not be new to limit this practicality with this
The interest field of type, therefore the equivalent variations made according to the utility model claims, still belong to the model that the utility model is covered
Enclose.
