Technical Field

[0001] The utility model relates to the technical field of water dispensers, and in particular to an integrated water supply reverse osmosis water purifier. Background Art

[0002] Reverse osmosis water purifier is currently the safest purification process. The water quality meets the direct drinking standard and is the consumer's first choice of water purification product. The application scenarios are becoming more and more extensive. It is not only used for cooking and drinking. Nowadays, people choose purified water for washing. There is an increasing demand for families to install a water purifier and choose multiple water use points. The water outlet pressure of the reverse osmosis water purifier is low. Some pipelines for multiple water use are long from the water purifier. The water outlet pressure of some water use points cannot be met by the water purifier on the next floor. Some water use points are used less frequently, and the stale water in the pipeline is too long, affecting the water quality.

[0003] In view of this, the present utility model is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide an integrated water supply reverse osmosis water purifier. The utility model reverse osmosis water purifier is provided with a circulating water supply device, so that the water outlet pressure of the water purifier is constant and circulating water supply is realized. At the same time, the ultraviolet sterilization lamp can circulate and sterilize the transported pure water, making the transported pure water safer. One water purifier can meet the water needs of multiple points in the whole house of an average family.

[0005] In order to achieve the above-mentioned purpose of the present invention, the following technical solutions are adopted:

[0006] The utility model provides an integrated water supply reverse osmosis water purifier, comprising a circulating water supply device, wherein a circulating pipeline and a breathing pipeline are provided in the circulating water supply device, one end of the breathing pipeline is connected in series with the circulating pipeline through a water outlet faucet; a breathing interface is provided on the top of the pure water tank, and the other end of the breathing pipeline is connected to the pure water tank through the breathing interface.

[0007] In the present invention, the water outlet faucet has two interfaces, one of which is directly connected to the breathing tube, and the breathing tube is directly connected to the pure water tank through the water outlet faucet. That is to say, in the present invention, the breathing tube and the breathing filter are always in an open state. The other interface of the water outlet faucet is connected to the circulation pipeline. When water is needed, the water outlet faucet is opened, and water from the inside of the water tank passes through the splitter to reach the water outlet faucet and flows out from the water outlet faucet; when water is not needed, the faucet is closed, and water flows out from the inside of the water tank and circulates continuously through the circulation pipeline. Since an ultraviolet sterilization lamp is also provided in the circulation pipeline, the water flow in the circulation pipeline can be circulated and sterilized, thereby ensuring that the water inside the water tank remains active and preventing the water from being stagnant in the pipeline for too long and affecting the water quality.

[0008] When it is detected that the water tank has not reached the high liquid level for 5 consecutive minutes and the water purifier is in standby mode, start the water purifier to replenish the water tank to avoid the circulating water working without stopping.

[0009] Preferably, as a further specific implementation method, a water tank outlet is provided on the side of the pure water tank, and a water tank return port is provided next to the breathing interface; the circulation pipeline is provided with a one-way valve, a delivery pump, an ultraviolet sterilization lamp, a splitter, a water outlet faucet, a pressure switch, and a return water limiting valve in sequence along the direction of the water tank outlet; and the circulation pipeline is connected to the pure water tank through the water tank outlet and the water tank return port.

[0010] Preferably, as a further specific embodiment, two interfaces are provided at the bottom of the water outlet faucet, one of which is connected to the breathing pipeline, and the other is connected to the splitter on the circulation pipeline, and the splitter of the circulation pipeline is provided with water outlet and return water interfaces for branching water supply; a breathing filter is provided in the breathing pipeline between the pure water tank and the water outlet faucet.

[0011] Preferably, as a further specific embodiment, a pure water tank water inlet is provided on the top of the pure water tank, and the pure water tank is connected to the purification system through the pure water tank water inlet; a composite filter element, an RO filter element and an activated carbon filter element are sequentially provided inside the purification system.

[0012] Preferably, as a further specific implementation, a water inlet solenoid valve and a booster pump are sequentially arranged between the composite filter element and the RO filter element; a one-way valve and a pressure switch are sequentially arranged between the RO filter element and the activated carbon filter element.

[0013] Preferably, as a further specific implementation, a combined solenoid valve is provided at the concentrated water outlet at the bottom of the RO filter element; and a water tank water replenishment solenoid valve is provided between the activated carbon filter element and the pure water tank.

[0014] Preferably, as a further specific implementation manner, a liquid level sensor and a mechanical float switch are further provided in the pure water tank for monitoring and controlling the water level in the pure water tank.

[0015] In the present invention, mechanical float switches are installed at both the water tank's return port and the water tank's water inlet to monitor and control changes in the water tank's water level. A liquid level sensor monitors the water level within the tank. When the water level changes, the sensor transmits a signal back to the circuit control board, which controls the tank's water replenishment solenoid valve to replenish and stop replenishment based on the actual water level within the tank. If the liquid level sensor fails and the circuit control board fails to receive a signal, the float of the water replenishment mechanical float switch rises, shutting off the water inlet to the tank. Even after the mechanical float switch is closed, the water purification system can still automatically stop. When the high water level drops to a set position, the water purification system automatically restarts to replenish water, maintaining the water level within the pure water tank. The transported pure water pipeline is supplied to the water outlet faucet through the one-way valve, ultraviolet sterilization lamp, and splitter in turn. The return water pipeline returns to the pure water tank through the splitter, high-pressure switch, flow limiting valve, and return water mechanical float switch in turn. The return water flow limiting valve is used to increase the resistance of the return water to maintain a constant water pressure in the circulation pipeline; when the pure water tank is full of water and the return water mechanical float switch is closed, the water pressure in the circulation pipeline increases, triggering the pressure switch to disconnect, and the delivery pump stops working. When the water outlet faucet uses water, the water pressure in the circulation pipeline drops, the pressure switch closes, and the delivery pump starts to circulate water and sterilize.

[0016] Preferably, as a further specific embodiment, the splitter is provided with a main water inlet pipe and a main water return pipe, and the main water inlet pipe and the main water return pipe are respectively provided with a water outlet interface and a water return interface; the main water inlet pipe is used to deliver pure water to the water use point; the pure water returns to the pure water tank through the main water return pipe.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] This patented technology integrates a water circulation system inside the reverse osmosis water purifier, which realizes the automatic delivery of pure water to the water use point. The water supply cycle is circulated and sterilized by ultraviolet light. Not only is the water output large, but the problem of long pipes is not a problem. A family can install a water purifier to meet the needs of multiple water use points. The water outlet pressure of the reverse osmosis water purifier is low. The multi-point water use pipes are long from the water purifier. The water outlet of the water purifier at the water point is constant through the integrated water supply of this patent to meet the water demand. For water use points with low frequency, this patented technology realizes circulating water supply and ultraviolet sterilization to avoid the water quality being affected by the long-term stale water in the pipes.

[0031] In order to more clearly illustrate the technical solution of the present invention, it is described below in the form of specific embodiments.

[0032] Example

[0033] Reference Figure 1 、 Figure 2 and Figure 3 An integrated water supply reverse osmosis water purifier includes a pure water tank 9. The top of the pure water tank is provided with a breathing port 24, a water tank water inlet 22, and a water tank return port 21. One end of the breathing pipe 16 is connected to the pure water tank 9 through the breathing port 24; the other end of the breathing pipe 16 is connected in series with the circulation pipe 19 through the water outlet faucet 14. The bottom of the water outlet faucet 14 is provided with two interfaces for connecting the circulation pipe 19 and the breathing pipe 16. A breathing filter 23 is provided between the pure water tank 9 and the water outlet faucet 14.

[0034] A water outlet 20 is located on the side of the pure water tank. Along the water outlet 20, a check valve 7-1, a delivery pump 10, an ultraviolet germicidal lamp 15, a manifold 13, a pressure switch 6-1, a return flow limiting valve 12, and a return flow mechanical float switch 18 are located. The check valves 7 and 7-1 control the flow of water and prevent backflow. The delivery pump 10 provides pressure for the water to circulate through the pipeline. The ultraviolet germicidal lamp 15 performs repeated sterilization. The manifold 13 is equipped with a main water inlet pipe and a main return pipe, each with an outlet and return connection, respectively. This manifold 13 allows for a circulating water supply to each water point. The pressure switches 6-1 and 6 monitor the pressure in the pipeline and transmit signals. The return flow limiting valve 12 maintains a constant water flow and stabilizes the water pressure in the circulation pipeline 19.

[0035] The water outlet tap 14 is connected to the circulation pipeline 19 and the breathing pipeline 16. The breathing pipeline 19 is constantly exchanging gas with the external environment through the water outlet tap 14. The purpose of this arrangement is that when the pure water tank 9 is replenished with water, the air inside needs to be discharged. If the air in the pure water tank 9 cannot be discharged when replenishing water, the air inside the pure water tank 9 will be compressed; when the pure water tank 9 is pumping water, if no air enters the pure water tank 9, the pure water tank 9 will form a siphon state. In order to connect to the external environment, a breathing filter 23 needs to be set between the breathing interface 24 and the water outlet tap 14. The breathing filter 23 is used to filter the air intake of the pure water tank 9 to ensure hygiene and safety. When water is needed, the water in the circulation process flows out from the water outlet faucet 14 or other water use points; when water is not needed, the water outlet faucet 14 is closed, and the water in the water tank 9 flows out through the water outlet 20 of the water tank, and is powered by the delivery pump to continuously pump the water in the water tank 9 into the circulation pipeline 19, and continuously pass through the ultraviolet germicidal lamp 15 for sterilization circulation, thereby ensuring the activity of the water in the water tank 9 and preventing the stale water from affecting the water quality for too long.

[0036] The top of the pure water tank 9 is equipped with a water inlet 22, which is connected to the purification system. The purification system is equipped with a composite filter element 1, an RO filter element 4, and an activated carbon filter element 8. The activated carbon filter element 8 is connected to the water inlet 22 via a water tank water supply solenoid valve 11. A water inlet solenoid valve 2 and a booster pump 3 are installed between the composite filter element 1 and the RO filter element 4. A check valve 7 and a pressure switch 6 are installed between the RO filter element 4 and the activated carbon filter element 8. A combined solenoid valve 5 is installed at the bottom of the RO filter element to discharge concentrated water.

[0037] The pure water tank is also equipped with a liquid level sensor 17, a mechanical float switch 18, and a water replenishment mechanical float switch 18-1 to monitor the water level within the pure water tank. The water replenishment mechanical float switch 18-1 shuts off the water inlet to the pure water tank 9 if the liquid level sensor 17 fails. The return water mechanical float switch 18 controls the circulating water supply. When the pure water tank 9 is full, the float of the return water mechanical float switch 18 rises, closing the return water mechanical float switch 18. At this point, the return water pressure in the water supply pipe increases momentarily when the water point is empty, triggering the high-pressure switch 6-1 to disconnect the signal feedback circuit control board and disconnect the power to the delivery pump 10 and the UV sterilizer 15. When the water point is drained, the water pressure in the return water pipe 19 drops to the activation pressure of the high-pressure switch 6-1, automatically activating the delivery pump 10 and the UV sterilizer 15.

[0038] The specific working process of the utility model when in use is as follows:

[0039] When the water purifier begins operation, water flows along the pipeline into composite filter element 1, where it undergoes preliminary filtration. The water inlet solenoid valve 2 controls the opening and closing of the pipeline. When the water purifier enters operating mode, the water inlet solenoid valve 2 opens, opening the pipeline and allowing water to flow through the solenoid valve 2 and into the booster pump 3. The booster pump 3 increases the water pressure to the required operating pressure, allowing the water to flow smoothly into the RO filter element 4. Once the water enters the RO filter element 4, it removes most dissolved solids, heavy metals, microorganisms, bacteria, viruses, and other substances from the water, resulting in purified water. Simultaneously, the concentrated water from the RO filter element 4 flows out through the capillary channel within the combined solenoid valve at the bottom, and then flows along the pipeline into the one-way valve 7. The one-way valve 7 controls the flow direction of pure water and prevents the pure water from flowing back after shutdown. After passing through the one-way valve 7, the pure water passes through the pressure switch 6 and enters the activated carbon filter element 8. The activated carbon filter element 8 can absorb substances harmful to the human body such as discoloration, odor, halogenated hydrocarbons and organic matter in the water. After the pure water is adsorbed again, the water tank water replenishment solenoid valve 11 in the pipeline is opened, and the purified pure water enters the pure water tank 9 through the water tank inlet 22.

[0040] The pure water tank 9 is equipped with a liquid level sensor 17 and a water mechanical float switch 18, which monitor and control the water level in the pure water tank 9. When the liquid level sensor 17 detects that the water level in the pure water tank 9 has reached the high level, it provides feedback. This feedback triggers the control circuit to shut off the power to the water supply solenoid valve 11, stopping the flow of water into the pure water tank 9. Simultaneously, the pressure in the pure water pipeline increases, driving the pressure switch 6. This feedback triggers the control circuit to shut down the water purifier. If the liquid level sensor 17 detects that the water level in the pure water tank 9 is low, it provides feedback again. This feedback triggers the circuit to output power to the water supply solenoid valve 11, opening it and allowing filtered pure water to continue entering the pure water tank 9. If the liquid level sensor 17 fails, the water level exceeds the high level, and the water supply mechanical float switch 18-1 promptly shuts off the water inlet to the pure water tank 9.

[0041] The purified water in the pure water tank 9 can be placed in the pure water tank for storage. When the water is stored for a long time, the purified water is sterilized through the circulation pipeline 19 and then returned to the pure water tank 9 for storage. The specific process is as follows: the water outlet tap 14 is closed, and the purified water enters the circulation pipeline 19 through the water tank outlet 20. The circulation pipeline 19 is provided with a one-way valve 7-1, which also prevents the purified water from flowing back. The purified water passing through the one-way valve 7-1 is then pressurized by the delivery pump 10 and sterilized again by the ultraviolet sterilization lamp 15, and then enters the splitter 13. The splitter 13 distributes and circulates the purified water. The use of the splitter 13 can avoid stale water in the pipeline. The purified water passing through the splitter 13 passes through the pressure switch 6-1, the return water limiting valve 12, and the return water mechanical float switch 18, and returns to the pure water tank 9 through the water inlet 21 of the circulation return pipeline.

[0042] When using the purified water in pure water tank 9, it enters circulation line 19 through water tank outlet 20. It then passes through one-way valve 7-1, through delivery pump 10 and ultraviolet germicidal lamp 15, and into splitter 13. After the purified water is diverted by splitter 13, outlet tap 14 is opened, and the water flows out through outlet tap 14 for use. At this point, breathing line 16 is connected to circulation line 19, and external air passes through outlet tap 14 along the pipeline into the breathing filter and into pure water tank 9, allowing pure water tank 9 to "breathe" healthily.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
