Description
Technical Field
The invention relates to the water treatment industry, in particular to the aspects of deep filtration and purification of drinking water.
Background
As the consumptive material of purifier, filter courage after using a period, need change the filter courage. However, with popularization of water purifiers, defects and shortcomings of the water purifiers in application are gradually exposed: the water purifier with middle and low price mostly adopts an open type liner configuration bare metal mode. The shell with the built-in liner is hung below the machine base, and the shell can be reused, so that the cost of replacing the liner by a consumer is correspondingly reduced by 10-20%, but the problems of single product structure, difficult liner replacement, difficult cleaning of the filter cavity and the like are correspondingly generated. The water purifier with the lower open filter cartridge is usually directly placed in a kitchen cabinet through a shell with a built-in liner, the water purifier is required to be taken out and put on the air when the liner is replaced, and then a special filter liner wrench is sleeved on the shell from bottom to top and is forcibly rotated to loosen the threaded connection of the shell and the machine base to detach the shell. After the new liner is replaced, the shell with the liner is tightly screwed below the machine base, and the whole operation process is very labor-intensive. Because the water purifier with water is heavy, and the built-in filter liner in the open filter cartridge is poured out together with the water after the filter cartridge is detached, the water pollution treatment is very troublesome, and the cleaning of the inner cavity of the filter cartridge is rarely performed until now. Moreover, because the liner is placed in the filter cylinder, water leakage is easy to occur due to a little carelessness during replacement. For the horizontal water purifier, the use is very convenient: can be placed on the table top of a kitchen cabinet or in the cabinet; the machine is only required to be directly placed at the using position, and the punching hanging machine is not required. Because the filter liner is positioned above the machine base, the filter liner is convenient to replace, and the time and the labor are saved relatively. However, the biggest problem of adopting the seat type water purifier structure is that the machine operation surface is small, the display component and the operation control device can only be arranged on the side elevation of the machine, the top surface is used for replacing the filter liner, and the water passing control component can be placed in no place. Since the water purifier has a limited length and width, which is generally less than 500 mm×200 mm×450 mm, the placement of the display control device on the machine side elevation will affect the number of filter liners to be placed. When the closed filter liner is used, water in the filter liner can flow out from the water gap of the filter liner to pollute the surrounding environment when the filter liner is replaced because the water gap of the filter liner faces downwards. The water in the filter element at the front and rear stages of the replaced filter element is also discharged from the water inlet and outlet pipelines of the corresponding machine seat of the detached filter element until the water level in the water purifier is balanced again, so that the seat type water purifier with the lower machine seat has the characteristic of convenient extraction of the filter element, but the mode is rarely adopted. When the built-in filter liner of the open filter cartridge is used, the built-in filter liner in the existing open filter cartridge is poured out together with water after the filter cartridge is detached, the operation is very troublesome, and an example of cleaning the inner cavity of the filter cartridge is rarely provided until now. Because the environment for placing the water purifier is generally poor, the leaked water flow rate in the process of replacing the filter liner is too fast to be removed, so that the operation is inconvenient, and the cabinet is soaked and even the cabinet plate is damaged. In view of the fact that the replacement of the filter liner is always accompanied with the whole use process of the water purifier, the related problems caused by the replacement of the filter liner and the cleaning of the filter channel can frequently occur repeatedly. In addition, the scaling phenomenon of the filter cylinder and the inner wall of the pipeline of the water purifier is very serious after the water purifier is used for a long time, and the water purifying treatment environment of the water purifier is worse. In particular, the problems of cleaning the inner cavity of the upper open type filter cartridge, discharging sewage containing a large amount of impurities and extracting the built-in filter liner are not solved, so that the model of the lower base is rarely adopted. Even, no water purifier has been marketed so far that can clean the filter cartridge. On the other hand, the replacement of the filter liner and the cleaning maintenance of the water purifier require the service of going to the gate by a professional, which is labor-consuming, time-consuming and not high in charge, and lack of cleaning means, and the professional is reluctant to provide the service of going to the gate, so that the problem of cleaning the machine is rarely mentioned to the user. Most users only know to replace the filter liner, but little is known to regularly clean the machine. In addition, the existing nanofiltration membrane and reverse osmosis membrane liner water purifier has serious waste of water resources. Typically, the "concentrate" discharged by the machine is 3-5 times the "pure water" produced. The concentrated water is purified water filtered by the filter liner of the front-end microfiltration membrane, and is very unfortunately discharged directly. The above-mentioned drawbacks and disadvantages make it difficult to obtain a water purifier that is more widely popularized.

The ratio of the discharged concentrated water discharged from the concentrated water outlet of the reverse osmosis membrane filter liner to the pure water flowing out from the pure water outlet is about 3:1, and the quality of the discharged concentrated water is the purified water after the filtering treatment of the pre-filter liner, so that the discharged concentrated water can be used as the purified water for washing, thereby avoiding a great amount of waste of water resources caused by directly discharging the discharged concentrated water into a sewer pipeline, and reducing the loss of a filter liner filter material layer corresponding to the treatment of the discharged concentrated water by the pre-filter liner.

In the above embodiment, the U-shaped filter cartridge bin may be a single-cavity structure in which the filter cartridge is placed, or a double-cavity structure in which the filter cartridge and the water passing control member are placed. Wherein, for a single-cavity structure, the filter liner or the filter liner and certain water passing control components are positioned in one cavity; if the single-chamber structure is to be provided as a water storage chamber, whether the water passing control member placed in the single-chamber structure is to be subjected to water-proof treatment or not is considered, if necessary, a sealing water-proof structure is added, or the water passing control member is moved outside the water storage chamber.

In addition, because the external concentrated water discharging port arranged on the upper module is higher than the U-shaped filter liner bin, concentrated water discharged from the concentrated water discharging port of the reverse osmosis membrane filter liner is pressurized and discharged from the external concentrated water discharging port and the external hose through the concentrated water discharging pump device. Especially for the cabinet type model, when the pressurized water outlet pipeline is communicated with the pure water pipeline to form a water outlet pipeline, the discharged concentrated water in the discharged concentrated water tank is pressurized and discharged out of the pure water faucet positioned on the counter through the concentrated water discharging pump device.
