As shown in fig. 1, the water-saving water purification apparatus of the present embodiment mainly includes a water purification device 10, a water storage tank 20, a first water-saving tap 31, and a second water-saving tap 32. The water purifying device 10 is provided with a water inlet 15 and two water outlets, namely a concentrated water outlet 17 and a pure water outlet 16. The water storage tank 20 is disposed downstream of the water purifying device 10, and the water inlet of the water storage tank 20 is connected to the concentrated water outlet 17. The first water saving tap 31 is disposed downstream of the water purifying device 10 and connected to the pure water outlet 16; a second water-saving tap 32 is provided downstream of the water storage tank 20 and connected to the water outlet of the water storage tank 20.

After the above water-saving water purification apparatus is adopted, tap water of the municipal water network can enter the water purification apparatus 10 from the water inlet 15, and cleaner pure water and the remaining concentrated water are produced through the water purification apparatus 10. Wherein pure water flows out from the water blowing water outlet, and concentrated water flows out from the concentrated water outlet 17. The first water saving tap 31 is provided downstream of the water purifying device 10 and is connected to the pure water outlet 16 of the water purifying device 10. When a user needs drinking water, the first water saving tap 31 can be opened, so that pure water produced by the water purifying device 10 can enter the first water saving tap 31 through the pure water outlet 16, and pure water can be taken from the first water saving tap 31. The water storage tank 20 is provided downstream of the water purifying device 10, and its water inlet is connected to the concentrated water outlet 17 of the water purifying device 10, and the concentrated water can be temporarily stored in the water storage tank 20. The water outlet of the water storage tank 20 is connected with a second water-saving tap 32, and when a user needs water other than drinking water such as dish washing, mopping or toilet flushing, the second water-saving tap 32 can be started to take concentrated water in the water storage tank 20. Therefore, water with different purification levels can be fully used, the utilization rate of the household tap water is improved, and the waste of water resources is effectively reduced.

Preferably, as shown in fig. 1, the first water saving tap 31 of the present embodiment is located higher than the second water saving tap 32. The first water-saving tap 31 and the second water-saving tap 32 which are inconsistent in height are obviously different, so that a user can conveniently distinguish the corresponding relation between the two water-saving taps and pure water and concentrated water, the user can be effectively helped to take water according to the needs, and the confusion of two kinds of water without water quality is avoided.

In addition to the manner in which the first water-saving faucet 31 and the second water-saving faucet 32 are disposed at different heights in this embodiment, it is also possible to dispose different marks for distinguishing the first water-saving faucet 31 and the second water-saving faucet 32, or to use the height distinction and the mark distinction at the same time, so as to avoid confusion of users.

The first water saving tap 31 corresponding to the pure water is higher than the second water saving tap 32 corresponding to the concentrated water, so that the concentrated water can be effectively prevented from splashing on the first water saving tap 31, and further, the pollution of the concentrated water to the first water saving tap 31 and the pure water flowing out of the first water saving tap 31 can be prevented.

In actual use, there may be a case where the water production demand of pure water is far greater than the use demand of concentrated water, or the household cleaning frequency is low, resulting in a low consumption rate of concentrated water in the water storage tank 20. In order to avoid that the water storage tank 20 is full of water and the water purification device 10 is used for preparing pure water, as shown in fig. 1, the water-saving water purification device of the present embodiment further comprises a drainage pipeline 50, wherein the drainage pipeline 50 is connected with the concentrated water outlet 17 and is connected in parallel with the pipeline where the water storage tank 20 and the second water-saving tap 32 are located. The drain port 80 at the end of the drain pipe 50 is connected to a sewer, and when the concentrated water in the water storage tank 20 is full, the concentrated water generated by continuing to prepare pure water can be discharged from the drain port 80 to the sewer through the drain pipe 50, so that the pure water preparation of the water purification device 10 is not affected even if the water storage tank 20 is full.

Further, as shown in fig. 1, the water saving and purifying apparatus of the present embodiment is provided with a first valve 41 at the concentrated water outlet 17, a second valve 42 at the water inlet of the water storage tank 20, and a third valve 43 on the water discharge line 50. The first valve 41, the second valve 42 and the third valve 43 are all preferably electromagnetic valves, and can be connected with a control panel of the water-saving water purifying device so as to control the on-off of each waterway in the water-saving water purifying device.

The water flow in each line may be indicated by reference to the arrows in fig. 1. For example:

when no water is required, the whole water-saving water purifying device is in a stop state, and the first valve 41, the second valve 42 and the third valve 43 are all in a closed and blocked state;

when the water storage tank 20 is not full due to water demand, the third valve 43 is closed, the first valve 41 and the second valve 42 are opened, the concentrated water outlet 17 is communicated with the water storage tank 20, so that pure water can flow out of the first water saving faucet 31, and the concentrated water can enter the water storage tank 20 and is temporarily stored;

when there is a demand for water and the water storage tank 20 is full, the second valve 42 is closed, the first valve 41 and the third valve 43 are opened, and the concentrated water outlet is communicated with the water discharge pipeline 50, so that pure water can flow out from the first water saving faucet 31, and the concentrated water is directly discharged into a sewer through the water discharge port 80.

To monitor the concentrated water volume in the water storage tank 20, as shown in fig. 1, a level gauge 21 is provided in the water storage tank 20 of the present embodiment, and the level gauge 21 is provided on the top of the water storage tank 20. When the liquid level of the concentrated water in the water storage tank 20 does not exceed the liquid level meter 21, the water storage tank 20 can still be considered to have water storage capacity, the water-saving water purifying device can control the second valve 42 to be opened and the third valve 43 to be closed, and the residual concentrated water for preparing pure water can be continuously injected into the water storage tank 20. When the liquid level of the concentrated water in the water storage tank 20 exceeds the liquid level meter 21, the water storage tank 20 can be considered to be full, and the water-saving water purifying device can control the second valve 42 to be closed and the third valve 43 to be opened, so that the concentrated water is discharged from the water outlet 80 through the water discharge pipeline 50. The liquid level meter 21 can also be connected with light, sound or other devices, so that the water-saving water purifying device can send out prompt information when the liquid level exceeds the liquid level meter 21, and remind a user to consume concentrated water.

The bottom area of the water storage tank 20 and the height of the liquid level meter 21 in the water storage tank 20 are preset data when the product is designed, and the specific water amount of the concentrated water in the water storage tank 20 when the liquid level reaches the liquid level meter 21 can be calculated according to the data.

As shown in fig. 1, the water saving and purifying apparatus of the present embodiment further includes a water pump 33, the water pump 33 being connected in series between the water storage tank 20 and the second water saving tap 32. The water suction pump 33 is used to pump the concentrated water in the water storage tank 20 so that the concentrated water can be discharged from the second water saving tap 32.

As shown in fig. 1, in the water saving and purifying apparatus of the present embodiment, the water purifying device 10 includes a first filter element 11, and both the concentrated water outlet 17 and the pure water outlet 16 are provided on the first filter element 11. Tap water from a municipal water network can enter the first filter element 11 from the water inlet 15, and pure water with suspended matters, inorganic salts, bacteria and other impurities in the water reduced after the tap water is filtered, adsorbed and other purifying effects in the first filter element 11 can flow out from the pure water outlet 16 and be provided for users. The remaining concentrated water can flow out of the concentrated water outlet into the water storage tank 20 or be discharged from the drain line 50 to a sewer.

Preferably, the first filter cartridge 11 of the present embodiment includes a Reverse Osmosis membrane (RO membrane) structure and an activated carbon filtration structure, which is disposed downstream of the Reverse Osmosis membrane structure. The RO reverse osmosis membrane is a filtering membrane with the finest filtering aperture at present, and can effectively filter heavy metals, bacteria, viruses, antibiotics and the like to obtain direct-drinking pure water. The active carbon filtering structure is arranged at the downstream of the RO reverse osmosis membrane, so that the taste of water quality can be further improved, and the water quality becomes more fresh, sweet and delicious as much as possible. The active carbon component in the active carbon filter structure is preferably high-efficiency active carbon so as to obtain better taste.

As shown in fig. 1, in the water-saving water purifying apparatus of the present embodiment, the water purifying device 10 further includes a second filter element 12, the second filter element 12 is disposed upstream of the first filter element 11, and a water outlet of the second filter element 12 is connected to a water inlet of the first filter element 11. The second filter element 12 may have a different filter element structure from the first filter element 11, and performs preliminary treatment on tap water before the tap water enters the first filter element 11, and filters out impurities such as larger particles, so as to improve the purification effect and the service life of the first filter element 11.

Preferably, the second filter element 12 of this embodiment may be a ppc composite filter element, specifically including a PP cotton and a carbon rod, where the PP cotton is a porous structure formed by fibers, and can filter out impurities with larger particles such as silt and rust, and the carbon rod can adsorb residual chlorine and abnormal odor in water, so that the water entering the first filter element 11 is purer.

In other embodiments not shown in the drawings, the first filter 11 may be a filter of other types, for example, a filter provided with only an RO membrane, which may affect the taste of the pure water produced to some extent, but may achieve similar effects. The second filter element 12 may be a simplified or more fully functional filter element, for example, different activated carbon structures may be disposed on the upstream and downstream sides of PP cotton to increase the filtering effect of the second filter element 12.

As shown in fig. 1, a water inlet valve 14 and a booster pump 13 are further disposed between the second filter element 12 and the first filter element 11 in this embodiment, and are used for controlling the on-off of water flow in the pipeline and providing pressure for the reverse osmosis in the first filter element 11. A check valve 60 and a high-pressure switch 70 are also arranged between the first filter element 11 and the first water saving tap 31, the check valve 60 is used for placing pure water in a pipeline to flow reversely, and the high-pressure switch 70 is used for controlling the on-off of the pipeline.
