[0026] Embodiment 1

[0027] Please refer to Figure 1 , this embodiment of the utility model discloses a water purifier with an ultra-large water output. The water purifier of this solution includes a composite filter element 1, a booster pump 2, an RO reverse osmosis filter element 3, a make-up water solenoid valve 4, a pure water tank 5, a centrifugal pump 6, and a water outlet 7. The composite filter element 1 includes a pre-filter element and a post-filter element. The pre-filter element, the booster pump 2, the RO reverse osmosis filter element 3, the post-filter element, the make-up water solenoid valve 4, the pure water tank 5, the centrifugal pump 6, and the water outlet 7 are sequentially connected through pipelines. For example, the flux of the RO reverse osmosis filter element 3 is 800G, that is, the flow rate is 2L / min per minute. When working, the make-up water solenoid valve 4 is opened, and the RO reverse osmosis filter element 3 makes water for the pure water tank 5 until the pure water tank 5 is full. When water needs to be taken, the water outlet 7 is opened, and the centrifugal pump 6 is started to pump out pure water at a flow rate of 5L / min, which is equivalent to the water output flow rate of a 2000G RO reverse osmosis filter element 3. By adopting such a design method, the small-flux RO reverse osmosis filter element 3 can be used to make water in advance and store it in the pure water tank 5. When water needs to be taken, the water outlet 7 is opened, and the centrifugal pump 6 is started, and then the pure water is pumped out at the flow rate required for a large flux (wherein, the water output flow rate can increase with the increase of the flow rate of the centrifugal pump 6). Since a smaller-flux RO reverse osmosis filter element 3 can meet the water output requirements of a large flux, the production cost of the water purifier and the cost for users to replace the filter element can be reduced while meeting the large-flux requirements. In addition, due to the presence of the pure water tank 5, each time water is taken, it is not necessary to start the booster pump 2, and only the centrifugal pump 6 needs to pump water, resulting in lower noise compared to conventional water purifiers.

[0028] Among them, the pure water tank 5 of different volumes can be set according to actual conditions to meet the water needs of different users. It is not limited here. This embodiment takes a pure water tank 5 of 1 to 3L as an example.

[0029] In some embodiments, the water purifier with a super large water output can also support the use of pipeline machines, and the water outlet 7 can also be used to connect the pipeline machine. The water purifier with a super large water output also includes a pipeline machine solenoid valve 8 and a high-pressure switch 9, which are connected between the post-filter element and the water outlet 7 through pipes in turn. Among them, the high-pressure switch 9 is used to monitor the switch of the pipeline machine. If the pipeline machine is short of water, the high-pressure switch 9 is closed, and the booster pump 2 is started to replenish water to the pipeline machine through the pipeline machine solenoid valve 8; if the pipeline machine is full of water and stops, the high-pressure switch 9 is opened, the pipeline machine solenoid valve 8 is closed, and the booster pump 2 stops making water. With this design, if the user has a large water consumption and the pure water tank 5 is used up, the system can still achieve 2L / min of water output from the pipeline machine flow channel.

[0030] It is understandable that in other embodiments, according to actual needs, the pipeline machine and the pure water tank 5 can be used simultaneously to supply water, which is not limited here.

[0031] In some embodiments, considering that the TDS of the first cup of water in a large-throughput water purifier is prone to be high, in order to solve this problem, the water purifier with an ultra-large water output also includes a pure water reflux solenoid valve 11 and a pressure relief valve 12. The pure water reflux solenoid valve 11 is arranged between the post-filter element and the water outlet 7, and the pressure relief valve 12 is connected between the water outlet end of the centrifugal pump 6 and the water inlet end of the booster pump 2. After the water purifier stops taking water, the water replenishment solenoid valve 4 can be closed, the water outlet 7 can be closed, and the pure water reflux solenoid valve 11 can be opened. The high-concentration water at the front end of the reverse osmosis membrane of the RO reverse osmosis filter element 3 can be refluxed to the water inlet end of the booster pump 2 through the pure water reflux solenoid valve 11 and the pressure relief valve 12, replacing the high-concentration water at the front end of the reverse osmosis membrane of the RO reverse osmosis filter element 3, thereby realizing a pure water bubble membrane. This measure not only solves the problem of high TDS of the first cup of water but also improves the life of the RO reverse osmosis filter element 3.

[0032] Preferably, the pure water reflux solenoid valve 11 and the pipeline machine solenoid valve 8 are the same solenoid valve. With such a design, the structure of the water purifier can be simplified. In other embodiments, two solenoid valves can be separately provided, which is not limited here.

[0033] In some embodiments, in order to monitor the amount of water in the pure water tank 5 in time, a liquid level switch 17 is provided in the pure water tank 5, and the liquid level switch 17 is used to detect the change of the liquid level in the pure water tank 5. Specifically, the liquid level switch 17 can be used to detect the lowest preset liquid level and the highest preset liquid level. When the liquid level switch 17 detects the lowest preset liquid level, the water purifier produces water for storage, and when the liquid level switch 17 detects the highest preset liquid level, the water purifier stops producing water.

[0034] In some embodiments, considering that bacteria are likely to breed in the pure water tank 5 where pure water is stored, an antibacterial lamp 18 is further provided in the pure water tank 5, and the antibacterial lamp 18 is used for sterilization and antibacterial protection.

[0035] In some embodiments, the water purifier with a super-large water output further includes a water inlet solenoid valve 13. The water inlet end of the water inlet solenoid valve 13 is connected to the water outlet end of the pre-filter, and the water outlet end of the water inlet solenoid valve 13 is connected to the water inlet end of the booster pump 2. With such a setting, when the water purifier needs to produce water, when the water inlet solenoid valve 13 is opened, the booster pump 2 can pump water; when the water purifier does not need to produce water, the water inlet solenoid valve 13 is closed, and the booster pump 2 cannot pump water.

[0036] In some embodiments, considering that waste water will still be generated during the filtration of the RO reverse osmosis filter element 3, the water purifier with a super-large water output further includes a waste water solenoid valve 14, and the waste water solenoid valve 14 is connected to the waste water outlet 7 of the RO reverse osmosis filter element 3. With such a design, the concentrated water generated by the RO reverse osmosis filter element 3 can be discharged through the waste water solenoid valve 14.

[0037] In some embodiments, in order to prevent the pure water discharged by the RO reverse osmosis filter element 3 from flowing back during the water production process and affecting the user experience, the water purifier with a super-large water output further includes a first check valve 15, and the first check valve 15 is arranged between the RO reverse osmosis filter element 3 and the post-filter to prevent the pure water discharged by the RO reverse osmosis filter element 3 from flowing back.

[0038] In some embodiments, the water purifier with a super-large water output further includes a second check valve 16, and the second check valve 16 is arranged between the centrifugal pump 6 and the water outlet 7 to prevent the water at the water outlet 7 from flowing back to the pure water tank 5.

[0039] A water purifier with a super-large water output provided by the present utility model includes a water purifier with a super-large water output including a composite filter element 1, a booster pump 2, an RO reverse osmosis filter element 3, a make-up water solenoid valve 4, a pure water tank 5, a centrifugal pump 6 and a water outlet 7. The composite filter element 1 includes a pre-filter and a post-filter, and the pre-filter, the booster pump 2, the RO reverse osmosis filter element 3, the post-filter, the make-up water solenoid valve 4, the pure water tank 5, the centrifugal pump 6 and the water outlet 7 are sequentially connected through pipelines. With such a design, the RO reverse osmosis filter element 3 with a small flux can be used to produce water in advance and store it in the pure water tank 5. When water needs to be taken, the water outlet 7 is opened and the centrifugal pump 6 is started, and then the pure water is pumped out at a flow rate required for a large flux (wherein the water flow rate can increase with the increase of the flow rate of the centrifugal pump 6). Since a smaller flux RO reverse osmosis filter element 3 can meet the large flux water outlet demand, the production cost of the water purifier and the cost for the user to replace the filter element can be reduced while meeting the large flux requirement. In addition, due to the presence of the pure water tank 5, each time water is taken, it is not necessary to start the booster pump 2, and only the centrifugal pump 6 needs to pump water, resulting in lower noise compared to conventional water purifiers.

[0040] The technical means disclosed by the solution of the present utility model are not limited to those disclosed in the above embodiments, but also include technical solutions formed by any combination of the above technical features. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications are also regarded as the protection scope of the present utility model.
