Detailed implementation mode

[0039] Next, in combination with the implementation mode of the present invention, the technical solutions in the implementation mode of the present invention will be clearly and completely described. Obviously, the described implementation mode is only a part of the implementation modes of the present invention, rather than all the implementation modes. Based on the implementation modes in the present invention, all other implementation modes obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0040] As Figures 1 to 5 shown, the water purification device of the present invention includes a pre-filter mechanism 1, a booster pump 2, a reverse osmosis device 3, a water tank 4, a water-using terminal 5, a first pipe 6, a second pipe 7, a third pipe 8, a fourth pipe 9, a water pump 10, a pressure regulating valve 11, a water production valve 12, a water-using cut-off valve 13, an overflow pipe 14, a drain pipe 15, a wastewater ratio 16, a flushing valve 17 and a water stop valve 00.

[0041] The water purification device of the present invention can meet the water-using requirements of different scenarios and can be applied to a variety of water-using terminals, such as humidifiers.

[0042] Among them, the pre-filter mechanism 1, the booster pump 2, the reverse osmosis device 3, the water tank 4 and the water-using terminal 5 are connected in series through the first pipe 6 in sequence. This is a conventional water purification pipeline. After the water flow enters the pre-filter mechanism 1, it will be preliminarily filtered, and then the pipeline pressure is increased by the booster pump 2, so that the water flow passes through the reverse osmosis device for osmotic filtration, and then enters the water tank 4. The water tank 4 is used for storing water and outputting the water to the water-using terminal 5, or the water can be precipitated first and then the water is transported to the water-using terminal 5.

[0043] Specifically, the first pipe 6 includes a first pipe section 61, a second pipe section 62, a third pipe section 63 and a fourth pipe section 64. Among them, the first pipe section 61 is used to connect the pre-filter mechanism 1 and the booster pump 2; the second pipe section 62 is used to connect the booster pump 2 and the reverse osmosis device 3; the third pipe section 63 is used to connect the reverse osmosis device 3 and the water tank 4; the fourth pipe section 64 is used to connect the water tank 4 and the water-using terminal 5. In this way, the water flow will sequentially pass through the pre-filter mechanism 1, the booster pump 2, the reverse osmosis device 3 and the water tank 4 and enter the water-using terminal 5.

[0044] Since the water sources vary in quality and the quality of the incoming water is uneven, if only one pipeline is used for treatment, all components will be put into operation. For example, when the water quality is excellent, it can directly meet the water demand of the water-using terminal 5. Obviously, it is not cost-effective to put all components into operation, which will not only affect the service life of the components but also increase the operation and maintenance costs. Therefore, in this device, a second pipeline 7, a third pipeline 8, and a fourth pipeline 9 are also provided. Among them, one end of the second pipeline 7 is connected to the pre-filtering mechanism 1 through the first pipeline 6, and the other end is connected to the water-using terminal 5 through the first pipeline 6 and can be selectively switched on and off. In this way, when the water supply pressure is high and the water quality is excellent, the water flow does not need to be pressurized by the booster pump 2 and does not need to be filtered by the reverse osmosis device 3. The water flow can directly enter the water-using terminal 5 through the pre-filtering mechanism 1, the first pipeline 6, and the second pipeline 7, which can improve the water supply efficiency and reduce the number of components put into operation, so as to reduce the maintenance cost of this device and extend the service life of the components at the same time.

[0045] Specifically, one end of the second pipeline 7 is connected to the first pipe segment 61, and the other end is connected to the fourth pipe segment 64. In this way, the water flow can directly enter the water-using terminal 5 through the pre-filtering mechanism 1, the first pipeline 6, and the second pipeline 7.

[0046] One end of the third pipeline 8 is connected to the second pipeline 7, and the other end is connected to the water tank 4 and can be selectively switched on and off. In this way, when the water supply pressure is high but the water quality is slightly poor, the water flow does not need to be pressurized by the booster pump 2 and does not need to be filtered by the reverse osmosis device 3. It only needs to enter the water tank 4 through the third pipeline 8 for precipitation and then can enter the water-using terminal 5 for use, which can also improve the water supply efficiency and reduce the operating components.

[0047] One end of the fourth pipeline 9 is connected to the water tank 4, and the other end is connected to the water-using terminal 5 through the first pipeline 6 and can be selectively switched on and off. And the interface of the fourth pipeline 9 with the water tank 4 is located at the low liquid level of the water tank 4, and the interface of the first pipeline 6 with the water tank 4 is located at the high liquid level of the water tank 4. In this way, the water in the water tank 4 can be selectively transported to the water-using terminal 5 through the first pipeline 6, or the water in the water tank 4 can be transported to the first pipeline 6 through the second pipeline 7 and then transferred to the water-using terminal 5 by the first pipeline 6. Usually, the water at the high liquid level has better quality due to precipitation compared to the low liquid level. Therefore, selective water supply can be carried out according to the water demand of the water-using terminal.

[0048] Specifically, one end of the fourth pipeline 9 is connected to the water tank 4, and the other end is connected to the fourth pipe segment 64. In this way, when the water tank 4 supplies water at the low liquid level through the fourth pipeline 9, the water can be directly sent to the water-using terminal 5 through the fourth pipe segment 64 without the water-using terminal 5 opening an additional pipe orifice to connect the fourth pipeline 9.

[0049] Furthermore, a heating component is provided inside the water tank 4. The heating component can be an electric heating pipe, which is used to heat the water in the water tank 4 to meet the demand for hot water at the water usage terminal, expanding the application scenarios of this device.

[0050] When the volume of the water tank 4 is relatively large, due to the fixed heating component, its heating efficiency will be very low. Therefore, in order to improve the heating efficiency, a water pump 10 and a pressure regulating valve 11 are provided. Among them, the water pump 10 is connected in series on the fourth pipeline 9; the pressure regulating valve 11 is connected in series on the fourth pipe section 64; the fourth pipeline 9 and the fourth pipe section 64 cooperate to form a water circulation loop, and are selectively opened and closed for the water outlet and return of the water tank 4. With the above structure, the fourth pipe section 64 of the first pipeline 6 can cooperate with the fourth pipeline 9 to circulate and regulate the pressure of the water in the water tank 4, increasing the fluidity of the water and effectively improving the heating efficiency.

[0051] To control the water flow of this water purification device, a water production valve 12 and a water usage cut-off valve 13 are provided. Among them, the water production valve 12 is connected in series on the first pipeline 6 and is located between the pre-filter mechanism 1 and the booster pump 2. The water usage cut-off valve 13 is connected in series on the first pipeline 6 and is located between the water tank 4 and the water usage terminal 5. In this way, the water flow into the reverse osmosis device 3 can be controlled through the water production valve 12, and the water flow supply to the water usage terminal 5 can be controlled through the water usage cut-off valve 13 to selectively carry out water treatment work.

[0052] This water purification device also includes an overflow pipe 14, a drain pipe 15, a wastewater ratio 16, and a flushing valve 17. Among them, one end of the overflow pipe 14 is connected to the high liquid level of the water tank 4, and the other end is a free end. The overflow pipe 14 is used to overflow the excess water in the water tank 4; one end of the drain pipe 15 is connected to the low liquid level of the water tank 4, and the other end is communicated with the overflow pipe 14; the drain pipe 15 is used to drain the water in the water tank 4 and can be used for cleaning; the wastewater ratio 16 and the flushing valve 17 are connected in parallel, and the flushing valve 17 is connected to the reverse osmosis device 3 through a pipeline. With the above structure, the overflow pipe 14 and the drain pipe 15 are connected, which can reduce the number of water outlet ports and is conducive to drainage. Among the wastewater ratio 16 and the flushing valve 17, the flushing valve 17 adopts a self-flushing delay solenoid valve to regulate the inlet water pressure of the reverse osmosis device 3 to achieve the purpose of water production.

[0053] In this device, the execution control component for selective opening and closing is the stop valve 00. The stop valve 00 is used to control the opening and closing of the pipeline and can prevent the water flow from flowing turbulently in multiple pipelines.

[0054] Specific implementation steps

[0055] In the case of poor water quality and low water supply pressure, the water flow is transported in the first pipeline 6, filtered by the pre-filter mechanism 1, boosted by the booster pump 2, filtered by the reverse osmosis device 3 in sequence, then enters the water tank 4, and then is transported to the water usage terminal 5 through the water tank 4 by the fourth pipe section 64.

[0056] In the case of poor water quality but high water supply pressure, the water flow is transported in the first pipeline 6. The water flow is filtered by the pre-filtering mechanism 1 in sequence, enters the water tank 4 through the second pipeline 7 and the third pipeline 8 for precipitation, and then is transported to the water-using terminal 5 through the fourth pipe section 64 by the water tank 4.

[0057] In the case of good water quality and high water supply pressure, the water flow is first filtered by the pre-filtering mechanism 1, and then flows through the first pipe section 61, the second pipeline 7 and the fourth pipe section 64 and is directly transported to the water-using terminal 5.

[0058] According to the water quality demand for use, if the requirement is relatively low, the water in the water tank 4 can also be transported to the fourth pipe section 64 through the fourth pipeline 9 and then transported to the water-using terminal 5.

[0059] When it is necessary to heat water, the heating component in the water tank 4 is started, and the water in the water tank 4 is circulated through the fourth pipeline 9, the water pump 10 and the fourth pipe section 64 to improve the water circulation and speed up the heating of hot water; the overflow pipe 14 is used to overflow the excess water in the water tank 4, the drain pipe 15 is used to drain the water in the water tank 4 and can be used for cleaning, and the stop valve 00 is used to control the flow of the pipeline to prevent the water flow from flowing chaotically in multiple pipelines.

[0060] The above is only the preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
