Problems solved by technology

[0009] The above situation shows that when the current reverse osmosis water purifier is shut down, the solute in the concentrated water on the raw water side of the reverse osmosis membrane will pass through the reverse osmosis membrane, and the amount of penetration is positively correlated with time. The longer the time, the higher the TDS value of the produced water. The greater the range, the water purifier with a longer shutdown time will eventually lead to a significant increase in the TDS value of the initial effluent when it is restarted, or even exceed the standard, and the water quality is obviously not as good as the effluent water quality in stable operation.
The water purifier in the prior art solves the above-mentioned problems by connecting a product water return pipe to the water production pipe of the reverse osmosis module and connecting it with the inlet pipe of the high-pressure pump, but it needs to consume a large amount of water production, resulting in waste of water

Embodiment 1

[0032] Such as figure 1 Shown is a schematic structural diagram of a water purifier provided by the present invention. The water purifier in this embodiment includes: a first pretreatment filter element 1 , a membrane processor 2 , a pressure water storage tank 3 and a water pump 4 . The pressure water storage tank 3 includes: a housing 31 and a flexible diaphragm 32 . The flexible diaphragm 32 is arranged in the middle of the housing 31 , and its periphery is sealed and fixed with the inner wall of the housing 31 , dividing the inner space of the housing 31 into a water cavity 33 and an air cavity 34 . The housing 31 is provided with an air nozzle 35 which communicates with the air cavity 34 . A water nozzle 36 is also provided on the housing 31 , which communicates with the water chamber 33 .

[0033] The water inlet of the first pretreatment filter element 1 is connected to the water source, and the water outlet is connected to the inlet of the membrane processor 2 . The...

Embodiment 2

[0040] Such as image 3 As shown, it is a structural schematic diagram of another water purifier provided by the present invention. The difference between the water purifier in this embodiment and the water purifier in Embodiment 1 is that the water purifier in this embodiment The pressure water storage tank includes: a housing 301 and a bag-shaped flexible diaphragm 302 . The bag-shaped flexible diaphragm 302 is arranged inside the housing 301 , and the opening of the bag-shaped flexible diaphragm 302 is sealed and fixed with the faucet 306 on the housing 301 , and the faucet 306 communicates with the bag-shaped flexible diaphragm 302 . The bag-shaped flexible membrane 302 divides the inner space of the housing 301 into a water cavity 303 and an air cavity 304 . The inside of the bag-shaped flexible diaphragm 302 is a water chamber 303 , and the outside is an air chamber 304 . The housing 301 is provided with an air nozzle 305 which communicates with the air cavity 304 . T...

Embodiment 3

[0042] Such as Figure 4 As shown, it is a structural schematic diagram of another water purifier provided by the present invention. The difference between the water purifier in this embodiment and the water purifier in the second embodiment is that the water purifier in this embodiment also includes The inlet of the second pretreatment filter element 15 is connected to the water source, and the outlet thereof is connected to the water inlet valve 5 .

Abstract

The invention provides a water purifier which comprises a filter processor and a water production backflow pipe. A water stopper is arranged on the water production backflow pipe. The film processor is filled with filler. The filler is used for reducing the space capable of containing raw water or concentrate water in the film processor and then reducing the water yield of raw water or concentrate water through the water production backflow pipe. Compared with the prior art, the water purifier has the advantages that the film processor is filled with the filler, the space capable of containing raw water or concentrate water in the film processor can be reduced to the maximum extent, the volume of raw water or concentrate water needing to be replaced is reduced, and the consumed water yield is reduced to the maximum extent.

Description

technical field [0001] The invention relates to the technical field of water purification, in particular to a water purifier. Background technique [0002] Household reverse osmosis water purifiers have become a common water appliance because they can perform advanced treatment on municipal tap water, remove all pollutants in the water, and provide people with safe and high-quality drinking water. It usually includes a pretreatment filter element, a water pump and a reverse osmosis processor. Municipal tap water flows into the reverse osmosis processor after being treated by the pretreatment filter element. The water outlet flows out, and the water pump is arranged in the water inlet pipeline of the reverse osmosis processor to provide power for the water to pass through the reverse osmosis membrane. The reverse osmosis processor is equipped with a reverse osmosis membrane module, also known as a coiled membrane module. The coiled membrane module includes a core tube and a ...
