Description

Technical Field

[0001] The utility model relates to the technical field of water purifiers, in particular to a water purifier with an intelligent water-saving function. Background Art

[0002] A water purifier, also known as a water purifier or water purifier, is a water treatment device that deeply filters and purifies water according to the requirements of water use. The water purifier we usually talk about generally refers to a small purifier for home use. The principle of conventional household water treatment systems on the market is: after the raw water enters the water treatment system, it undergoes pretreatment and deep treatment, and then clean water can be obtained at the clean water outlet of the water treatment system. The concentrated water obtained during the filtration process is discharged through the concentrated water outlet of the water treatment system. Although the discharged concentrated water is not drinkable like clean water, it can still be used for other purposes. If it is discharged directly, it will cause waste.

[0003] Existing water purifiers do not have a water-saving function, so concentrated wastewater is directly discharged, causing waste. Therefore, there is an urgent need for a water purifier with an intelligent water-saving function. Utility Model Content

[0004] The purpose of the present utility model is to provide a water purifier with an intelligent water-saving function, so as to solve the problem that the existing water purifier proposed in the above background technology does not have a water-saving function, so that the concentrated wastewater is directly discharged, resulting in waste and the concentrated water after filtering is stored, but the concentrated water is prone to precipitation when left standing for a long time and still needs to be filtered.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a water purifier with an intelligent water-saving function, comprising a shell, a raw water pipe is arranged inside the shell, a first water pump is installed on the raw water pipe, and a PP cotton treatment barrel is connected to the left side of the raw water pipe, a granular carbon treatment barrel is arranged on the left side of the PP cotton treatment barrel, a sintered carbon treatment barrel is arranged on the left side of the granular carbon treatment barrel, a booster valve is installed on the left side of the sintered carbon treatment barrel, an RO membrane filter element is installed above the booster valve, a first connecting pipe is connected to the right side of the RO membrane filter element, and a concentrated water pipe is connected to the top of the RO membrane filter element, a clean water tank is installed on the right side of the first connecting pipe, a filter cartridge is arranged on the left side of the concentrated water pipe, and a second stopcock is installed on the concentrated water pipe. A reverse valve is provided, a filter plate is provided inside the filter cartridge, and a delivery pipe is connected to the bottom end of the filter cartridge, a return pipe is connected to the left side of the filter cartridge, a filler is provided below the filter plate, an ultrafine filter is provided below the filler, an activated carbon filter layer is provided at the end of the delivery pipe, a drain pipe is provided on the left side of the activated carbon filter layer, a second connecting pipe is connected to the left side of the drain pipe, and a threaded sleeve is sleeved on the outside of the drain pipe, a hose is connected to the left side of the second connecting pipe, a sedimentation water tank is provided at the bottom end of the hose, a perforated plate is provided inside the sedimentation water tank, and a discharge pipe is connected to the bottom end of the sedimentation water tank, a water outlet pipe is provided on the left side of the sedimentation water tank, a check plate is provided on the perforated plate, and a threaded cover is sleeved on the outside of the discharge pipe.

[0006] Preferably, the PP cotton treatment barrel, the granular carbon treatment barrel and the sintered carbon treatment barrel are connected through a raw water pipe, and the left side of the raw water pipe penetrates to the inner side of the RO membrane filter element.

[0007] Preferably, a first check valve is installed on the first connecting pipe, a clean water pipe is connected to the right side of the clean water tank, and a first water pump is installed on both the clean water pipe and the raw water pipe.

[0008] Preferably, the number of the filter plates is four, the four filter plates are provided with different filter holes, and the filler and the filter cartridge are fixedly installed via a bracket.

[0009] Preferably, both ends of the return pipe pass through the inner side of the filter cartridge, a second water pump is installed on the return pipe, a third check valve is installed on the delivery pipe, and a handle is fixed to the top of the sedimentation water tank.

[0010] Preferably, the second connecting pipe is connected to the drain pipe through a threaded sleeve and a threaded movable connection, the threaded cover is connected to the discharge pipe through a threaded movable connection, and a support block is provided at the bottom end of the sedimentation water tank.

[0011] Preferably, a transparent observation trough is provided on the outer wall of the sedimentation water tank, a sealing cover is provided on the water outlet pipe, and the angle between the check plate and the horizontal direction is 135°.

[0012] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0013] First, the utility model sets filter plates, ultrafine filters and reflux pipes. After the concentrated water passes through the four filter plates and the filler and is filtered, it falls on the ultrafine filter. If the concentrated water meets the standard after the initial filtration, it can pass through the ultrafine filter and fall into the delivery pipe, thereby entering the activated carbon filter layer. If it does not meet the standard, it will stay above the ultrafine filter and accumulate. The accumulated concentrated water is extracted into the reflux pipe and transported to the filter cartridge again for secondary filtration. It can reflux multiple times until the concentrated water meets the standard and can pass through the ultrafine filter, which can enhance the filtering effect of the concentrated water.

[0014] Second, the utility model provides a sedimentation water tank, a check plate, a perforated plate and a discharge pipe. The concentrated water is allowed to stand in the sedimentation water tank. The tiny impurities contained in the water begin to settle after standing, and pass through the perforated plate and the check plate thereon and fall to the bottom of the sedimentation water tank to accumulate. Since the angle between the check plate and the horizontal direction is 135°, the sediment will not float up when the sedimentation water tank is tilted to pour water, so that the concentrated water becomes ordinary water after settling and can be used directly. At the same time, the threaded cover can be opened to take out the sediment through the discharge pipe at the bottom. BRIEF DESCRIPTION OF THE DRAWINGS
