Description

Leak the reverse osmosis water dispenser in anti-

Technical field

The utility model relates to a kind of anti-interior reverse osmosis water dispenser that leaks.

Background technology

Present reverse osmosis water dispenser type both domestic and external, its system water process is basic identical, and flow process is: tap water → pre-flock → gac → reverse osmosis membrane → direct drinking water.Tap water reaches clean tap water with reverse osmosis after filtration, and water quality is good, because of its element manufacturing meticulous, all very high to the requirement of each accessory.Can produce some faults in actual use, the 1st, the foreign material that tap water is carried secretly can make entering water electromagnetic valve be not closed completely, thus internal leakage appears in disconnected not boiling water soruce; The 2nd, the water dispenser life-time service can be run into mishandle, super full water phenomenon occurs; The 3rd, water intaking valve existing problems itself are revealed in taking place.

The utility model is a weak point of avoiding prior art to exist, provides a kind of device simple, a kind of anti-interior reverse osmosis water dispenser that leaks that result of use is good.

Provided by the utility modelly leak the reverse osmosis water dispenser in anti-, its device includes by tap water water inlet intake pump, magnetic valve, strainer, jug and hot water and/or the cooling water outlet of process in proper order, emits to water tap behind water dispenser chilled water, hot water.Also be provided with the wiring board of device control circuit, pilot circuit is electrically connected with pump, magnetic valve.At the other flow-limiting valve that connects of strainer.Jug built-in one upper and lower mobile float, the fixed electric contact is electrically connected with pilot circuit on the float.Also being equipped with one in the jug can be with the unsteady ball float of the water surface, and ball float connects a fly rod, and fly rod can connect a plug, the water inlet of plug shutoff jug when ball float is in a high position around a turning axle rotation of being fixed in the tank skin that is filled with water on the fly rod.Jug has high, medium and low three water level reference mark, float control low-water level and median water level, high-water control ball float.

This utility model also has following feature: its jug built-in one vertical traveller, float is upper and lower two and slides along traveller, the baffle plate of fixed constraints float slip gauge on the traveller, the electric contact on baffle plate or the traveller matches with electric contact on pilot circuit and the float.

Described plug external fixation one layer of silica gel.

Described flow-limiting valve valve opening is a micropore.

The utility model has following advantage compared to existing technology: only carry out simple configuration in jug, do not influence the one-piece construction and the performance of water dispenser, be suitable for promoting.The accessory of new device is simply suitable, and it is all easy to make and install.This device can prevent internal leakage reliably, has eliminated a big disadvantage of water dispenser.

Description of drawings

Fig. 1 is the utility model process flow diagram;

Fig. 2 is the device for preventing leakage structural diagrams.

Embodiment

Referring to Fig. 1, it is the utility model technical process schematic illustrations, tap water at first passes through intake pump, order is flowed out by hot water 11 and/or cold water 12 outlets through magnetic valve, strainer, jug 1 again, emits for the end user to water tap after water dispenser is made cold water and/or hot water and drinks, said apparatus and operation are identical with common reverse osmosis water dispenser, strainer comprises reverse osmosis membrane filt, or is added with activated carbon filtration, or adds other pre-filter devices.Also be provided with the wiring board of device control circuit, pilot circuit is electrically connected with pump, magnetic valve, because of circuit card and pilot circuit are all ordinary skill, does not give expression among the figure.For making the water that overflows flow into the regulation place, connect a flow-limiting valve on the strainer side, valve opening is a micro channel in the middle of the described flow-limiting valve valve, behind the water inlet 6 of plug 5 shutoff jugs 1, the interior hydraulic pressure of strainer is raise, and forces leakage water to flow away from the flow-limiting valve micropore.

In jug 1, give high, medium and low three water level control limit points of setting earlier, in addition in Fig. 2 respectively with C, B, high, medium and low three the water level boundary points of three line index of A.In addition in jug 1 built-in one vertical traveller 7, be equipped with upper and lower mobile float 2 on the post, be fixed with the electric contact that is electrically connected with pilot circuit on the float 2, when water is in low-water level, electric contact on this float 2, the pilot circuit turn on pump on the control plate circuit plate supplies water.Float 2 rises with the water surface then, when the water surface reaches the median water level place, and the electric contact on the float 2, the pilot circuit on the control plate circuit plate closes pump cuts off the water supply, and keeps water level.Only when tap water, water level just descends, and float 2 also descends thereupon, and its process is gone round and begun again, control water dispenser works better.Everything goes well with your work in order to make, reliable, the utility model is provided with two floats 2, controls low-water level and median water level respectively.Upper and lower two floats 2 slide at buoyancy of water lower edge traveller 7, be fixed with the baffle plate 8 of restriction float 2 slip gauges on the traveller 7, two baffle plates 8 cooperate with upper and lower float 2 respectively, and set electric contact matches with electric contact on pilot circuit and the float 2 on baffle plate 8 or the traveller 7.

See Fig. 2, also be equipped with in the jug 1 in the water level active scope of a qualification, can be with the unsteady ball float 3 of the water surface, ball float 3 connects a fly rod 4 one ends, fly rod 4 the other ends can connect a plug 5 again, for adapting to technological operation around turning axle 10 rotations of being fixed in jug 1 wall on the fly rod 4, this plug 5 is to be connected on the pole of a bending of fly rod 4, as shown in the figure.For making shutoff water inlet 6 better effects if, in described plug 5 external fixation one layer of silica gel 9, fixing means can adopt existing several different methods.When water dispenser breaks down, after the water surface rises to median water level, no longer descend and continue to rise, when the water that generation is unusual leaks, the water surface will be higher than median water level will act on ball float 3, and the water inlet 6 that plug 5 will shutoff jug 1 when ball float 3 is in a high position does not make water overflow and causes unnecessary loss.Impel the flow-limiting valve work of reverse osmosis preceding device because water leaks the rising that produces hydraulic pressure this moment, and the water that pumps will enter outfall sewer through the flow-limiting valve micropore.When this device was between low-water level and the median water level normal running at jug 1 water surface, ball float 3 was inoperative, and plug 5 departs from the water inlet 6 of jug 1.
