The presently disclosed embodiment provides a steady flow water purifier 10, as shown in fig. 1, the steady flow water purifier 10 includes at least a pre-water-drive composite filter element 20 integrated with a pre-filter element and a water reservoir, a reverse osmosis filter element 30, a water inlet passage 40, a water purification passage 50, a pure water passage 60, a return passage 70, and a steady flow passage 80.

Wherein, the prepositive water drive composite filter element 20 is provided with a raw water inlet a, a purified water outlet b and a water inlet and outlet c of a water storage container; the reverse osmosis filter element 30 is at least provided with a purified water inlet d and a purified water outlet e.

One end of the water inlet passage 40 is connected to the raw water inlet a of the pre-water-drive composite filter element 20, and the other end is connected to an external water source, so as to provide the raw water to be purified for the steady-flow water purifier.

One end of the purified water passage 50 is connected with the purified water outlet b of the front water-drive composite filter element 20, the other end is connected with the purified water inlet d of the reverse osmosis filter element 30, and the purified water passage 50 is provided with a first electromagnetic valve 501 and a booster pump 502.

One end of the pure water passage 60 is connected with the pure water outlet e of the reverse osmosis filter element 30, and the other end is connected with the water inlet and outlet c of the water storage container of the front water drive composite filter element 20; the pure water passage 60 is provided with a first check valve 601, a second check valve 602 and a high-pressure switch 603;

for example, the second check valve 602 may be a pressure relief valve, and the forward directions of the pressure relief valve of the first check valve 601 are all directions from the pure water outlet e to the water inlet and outlet c of the reservoir, and the forward directions are directions in which the first check valve 601 and the pressure relief valve allow water to flow; the high-pressure switch 603 is configured to be turned off when the pressure on the side of the front water-drive composite filter element 20 is greater than a preset threshold value, and turned on when the pressure on the side of the front water-drive composite filter element 20 is less than or equal to the preset threshold value.

One end of the return passage 70 is connected to the inlet/outlet c of the reservoir of the front water-driving composite filter element 20, and the other end is connected to the front of the reverse osmosis filter element 30 provided in the purified water passage 50, and the return passage 70 is provided with a second solenoid valve 701 and a third check valve 702.

For example, as shown in fig. 1, the other end of the return passage 70 may be connected between a first solenoid valve 501 provided in the water purification passage 50 and a booster pump 502. The forward direction of the third check valve 702 is the direction from the reservoir inlet/outlet port c to the booster pump 502, and the forward direction is the direction in which the third check valve 702 allows water to flow.

One end of the steady flow passage 80 is connected between the first check valve 601 and the second check valve 602, and the other end is a steady flow water outlet 1 of the steady flow water purifier 10; the steady flow passage 80 is provided with a zero pressure pump 801.

Illustratively, the steady flow water purifier 10 shown in FIG. 1 has at least three modes of operation: a water making mode, a steady flow mode and a reflux mode.

When this stationary flow water purifier 10 work is when making the water mode, first solenoid valve 501 and booster pump 502 open, at this moment, the raw water that outside water source was not purified gets into inhalant canal 40, and get into the raw water inlet a of leading water drive composite filter element 20 through this inhalant canal 40, after this leading water drive composite filter element 20 filters the large granule impurity and some coloured impurity in aquatic, export from the water purification delivery port b of this leading water drive composite filter element 20, avoid the impurity damage rearmounted first solenoid valve 501 of former aquatic, devices such as booster pump 502 and reverse osmosis filter element 30, thereby effectively improve this stationary flow water purifier 10's life. Because the first electromagnetic valve 501 and the booster pump 502 are opened, the purified water flowing out from the purified water outlet b of the pre-water-driven composite filter element 20 enters the reverse osmosis filter element 30 through the purified water inlet d of the reverse osmosis filter element 30 for filtration after being boosted by the booster pump 502. The pure water generated after being filtered by the reverse osmosis filter element 30 flows out from the pure water outlet e of the reverse osmosis filter element 30, and flows into the water storage container integrated in the front water drive composite filter element 20 from the water storage container inlet/outlet c of the front water drive composite filter element 20 through the pure water passage 60 to be stored.

When the steady flow water purifier 10 works in the steady flow mode, the first electromagnetic valve 501, the booster pump 502 and the zero pressure pump 801 are opened, the steady flow water purifier 10 produces water according to the above mode, and because the zero pressure pump 801 is opened, the pure water flowing out of the pure water outlet e of the reverse osmosis filter element 30 can be output from the steady flow water outlet 1 under the influence of the pumping force generated by the zero pressure pump 801, so that the steady flow water purifier is convenient for a user to take. Specifically, since the working power of the zero pressure pump 801 determines the flow rate of the pure water output from the steady flow water outlet 1, the working power of the zero pressure pump can be adjusted according to the actual flow rate requirement in practical application. In order to prevent the pure water introduced into the steady flow path 80 from flowing back to the reverse osmosis filter element 30, one end of the steady flow path 80 is connected between a first check valve 601 and a second check valve 602 provided in the pure water path 60, and the flow of the pure water from the reverse osmosis filter element 30 to the steady flow path 80 is restricted by the first check valve 601.

When the steady flow water purifier 10 works in the backflow mode, the first electromagnetic valve 501, the booster pump 502, the zero pressure pump 801 and the second electromagnetic valve 701 are opened, the steady flow water purifier 10 produces water according to the steady flow mode, and since the working power of the zero pressure pump 801 is set as required, and the flow rate of pure water obtained by filtering by the reverse osmosis filter element 30 may change along with the pressure of an external water source, the situation that the pressure of the zero pressure pump 801 near the reverse osmosis filter element 30 is too high may occur. When the pressure of the zero-pressure pump 801 near the reverse osmosis filter element 30 is greater than the threshold value of the second check valve 602, the second check valve 602 is opened, and the redundant pure water flows into the water storage container through the pure water passage 60 to be stored. However, the capacity of the reservoir is limited, and if the reservoir is full of pure water, the pressure of the high-pressure switch 603 near the side of the front water-driving composite filter element 20 is high, and when the pressure is higher than the threshold value of the high-pressure switch 603, the high-pressure switch 603 is closed, that is, the pure water in the pure water passage 60 is suspended from entering the reservoir. Because the second electromagnetic valve 701 is opened, the pure water stored in the water storage container is input to the front of the booster pump 502 through the return passage 70, and then enters the reverse osmosis filter element 30 again after being boosted by the booster pump 502 for filtration, so that closed-loop return flow is formed, and the waste of the pure water is avoided. When the pressure of the high-pressure switch 603 near the side of the front water-driven composite filter element 20 is reduced along with the reduction of the pure water amount in the water storage container in the backflow process, and the pressure is smaller than or equal to the threshold value of the high-pressure switch 603, the high-pressure switch 603 is opened, and the pure water which cannot be output through the flow stabilizing passage 80 in the pure water passage 60 can continuously flow into the water storage container for storage.

In the technical scheme provided by the embodiment of the present disclosure, the steady flow path 80 can carry out steady flow output to the pure water output by the reverse osmosis filter element 30, and simultaneously when the flow of the pure water output by the reverse osmosis filter element 30 is great, the pure water path 60 can transmit redundant pure water to the storage container for storage, and when the storage container is full of pure water, the backflow path 70 can also input the pure water which cannot be stored in the storage container to the reverse osmosis filter element 30 again, thereby realizing closed loop backflow and avoiding pure water waste.

In one embodiment, as shown in fig. 2, the steady flow path 80 is further provided with a heating element 802, the heating element 802 being provided between the zero pressure pump 801 and the steady flow water outlet 1.

For example, the heating element 802 may heat pure water output from the steady flow path 80, for example, to a preset temperature set by a user. Specifically, the heating element 802 heats pure water at a constant power at a temperature related to the operating power of the zero-pressure pump 801. If the working power of the zero-pressure pump 801 is high, that is, the flow rate of pure water in the steady flow passage 80 is high, the temperature after being heated by the heating element 802 is low; if the working power of the zero-pressure pump 801 is low, that is, the flow rate of pure water in the steady flow passage 80 is small, the temperature after being heated by the heating element 802 is high. Therefore, the power of the zero pressure pump 801 and the power of the heating element 802 can be set through the target temperature set by the user, the outlet water temperature of the stable water outlet 1 is accurately controlled to be the target temperature, and the user experience is improved.

In one embodiment, as shown in fig. 3, the steady flow path 80 is further provided with a third solenoid valve 803, and the third solenoid valve 803 is disposed between the zero pressure pump 801 and the heating member 802.

Illustratively, the third solenoid valve 803 is a normally closed solenoid valve that is opened when the steady flow water purifier 10 is operating in the steady flow mode and the return flow mode. The third solenoid valve 803 can prevent the steady flow water outlet 1 from dripping when the steady flow path 80 is long.

In one embodiment, as shown with reference to fig. 1 to 3, the reservoir water inlet/outlet port c may include an opening to which the pure water passage 60 and the return passage 70 are both connected, the opening being a water inlet when the pure water passage 60 inputs pure water to the reservoir; the opening is a water outlet when pure water in the reservoir is fully returned from the return passage 70. In practical application, the water storage container water inlet/outlet port c may further include two openings, i.e., a water storage container water inlet and a water storage container water outlet, and correspondingly, the pure water passage 60 is connected to the water storage container water inlet in the water storage container water inlet/outlet port c, and the backflow passage 70 is connected to the water storage container water outlet in the water storage container water inlet/outlet port c.

In one embodiment, as shown in FIG. 4, the steady flow water purifier 10 further includes a cold water pathway 90; one end of the cold water passage 90 is connected between the first check valve 601 and the second check valve 602, and the other end is a cold water outlet 2 of the steady flow water purifier 10; the cold water passage 90 is provided with a fourth solenoid valve 901.

Illustratively, the steady flow water purifier 10 may further include a water intake mode, and when operating in the water intake mode, the first solenoid valve 501, the booster pump 502, and the fourth solenoid valve 901 are open, and the zero pressure pump 801 and the second solenoid valve 701 are closed. The steady flow water purifier 10 produces water according to the water production mode, and the fourth electromagnetic valve 901 is opened, so that the pure water flowing out of the pure water outlet e of the reverse osmosis filter element 30 can be output from the cold water outlet 2 through the fourth electromagnetic valve 901, and is convenient for a user to take.

In one embodiment, as shown in fig. 5, a flow meter 902 is further disposed between the zero-pressure pump 801 and the first check valve 601.

Illustratively, the flow meter 902 is used to measure the flow rate of pure water flowing out of the pure water outlet e of the reverse osmosis filter element 30. The steady flow water purifier 10 can obtain a target flow set by a user through a human-computer interaction interface in advance, and during the working process, the working power of the zero pressure pump 801 can be adjusted according to the detection result of the flow meter 902 and the target flow, so that the water flow output by the steady flow passage 80 is the same as the target flow.

Or, the flow water purifier 10 may obtain a target temperature set by a user through a human-computer interface in advance, and during the operation, the operation power of the zero pressure pump 801 may be adjusted according to the detection result of the flow meter 902, the heating power of the heating element 802 and the target temperature, so that the temperature of the pure water output by the steady flow path 80 reaches the target temperature.

In one embodiment, as shown in fig. 6, the water inlet passage 40 is connected to a tap water line and is provided with a pressure reducing valve 401.

Illustratively, the pressure reducing valve 401 is used to stabilize the water pressure of the tap water, so that the pressure of the tap water flowing from the water inlet passage 40 to the front water-driven composite filter element 20 is constant, thereby avoiding the problem that the water pressure of the tap water is too high, which affects the operation of a water storage container integrated in the front water-driven composite filter element 20, and avoids the problem that the back pressure is too high, which affects the water production efficiency during the water production process of the water storage container.

In one embodiment, as shown in FIG. 7, the flow-stabilizing water purifier 10 further includes a waste water pathway 100; the reverse osmosis filter element 30 is also provided with a waste water outlet f.

Wherein, one end of the waste water passage 100 is the waste water outlet 3 of the steady flow water purifier 10, and the other end is connected with the waste water outlet f of the reverse osmosis filter element 30.

Illustratively, the steady flow water purifier 10 further comprises a bubble film mode, when the steady flow water purifier 10 operates in the bubble film mode, the booster pump 502 and the second electromagnetic valve 701 are opened, and the first electromagnetic valve 501, the zero pressure pump 801, the third electromagnetic valve 803 and the fourth electromagnetic valve 901 are all closed. Pure water stored in the water storage container integrated in the front water-drive composite filter element 20 at this moment is transmitted to the booster pump 502 through the return water passage 70, and then is conveyed to the concentrated water side of the reverse osmosis filter element 30 through the booster pump 502, replace the concentrated water of high TDS (Total dissolved solids) after the normal water production of the concentrated water side, avoid the problem that the concentrated water of high TDS permeates to the pure water side when the steady flow water purifier 10 does not work, and then avoided the problem that the TDS of the first cup of water is high after the steady flow water purifier 10 is static for a period of time, and user experience is improved.

In one embodiment, the waste water pathway 100 is provided with at least two concentrate solenoid valves 1001 with different waste water ratios.

For example, referring to fig. 7, the waste water path 100 may be provided with two concentrate solenoid valves 1001 having different ratios of waste water, and when the two concentrate solenoid valves 1001 are closed, the waste water generated from the reverse osmosis cartridge 30 may be directly discharged through the waste water outlet, i.e., the waste water path 100 discharges the waste water according to the ratio of the waste water actually generated from the reverse osmosis cartridge 30. When one of the two concentrate solenoid valves 1001 is opened, the waste water pathway 100 discharges waste water according to a waste water ratio corresponding to the opened concentrate solenoid valve 1001. Assuming that the wastewater ratios of the two concentrate solenoid valves 1001 are 1:2 and 1:3, respectively, when the concentrate solenoid valve 1001 having the wastewater ratio of 1:2 is opened, the wastewater pathway 100 discharges wastewater in the wastewater ratio of 1: 2; when the concentrate solenoid valve 1001 having a waste water ratio of 1:3 is opened, the waste water pathway 100 discharges waste water in a waste water ratio of 1: 3.
