[0035] Specifically, the resin tank 010 is filled with resin, the resin can be arranged in layers, the top of the resin tank 010 is provided with a soft water valve 020, the raw water inlet channel can be communicated with tap water, so that the tap water flows into the resin tank 010 to form a water flow, and the water distributor in the resin tank 010 can guide the water flow to be uniformly distributed on the cross section of the resin tank 010, so that the water flow can be uniformly contacted with the resin layer, thereby improving the efficiency and uniformity of ion exchange between the water and the resin layer, and the generated soft water can be output from the first soft water outlet channel 0212A.

[0036] The water purification system 003 comprises a pre-filter core 5011, a reverse osmosis filter core 502 and a post-filter core 5012 arranged in sequence in the water path direction, the pre-filter core 5011 is communicated with the first soft water outlet channel 0212A or the raw water outlet channel 0213A, and the pure water filtered by the post-filter core 5012 can be directly drunk.

When the soft water inlet electromagnetic valve 0216A is opened, the soft water passes through the pre-filter core 5011, the reverse osmosis filter core 202 and the post-filter core 5012 in sequence to finally generate soft water, and when the raw water inlet electromagnetic valve 0217A is opened, the tap water enters the mineral water pipeline 007 through the pre-filter core 5011, and part of the soft water can also enter the mineral water pipeline 007 to mix to generate mineral water.

[0039] The mineral water pipeline 007 is communicated with the water outlet end of the pre-filter core 5011 and the water outlet end of the post-filter core 5012, and is used for mixing the water filtered by the pre-filter core 5011 and part of the pure water filtered by the post-filter core 5012 into mineral water, wherein the mineral water can also be drunk.

[0040] That is, in the water dispenser in the embodiments of the present application, both mineral water and pure water can be directly dispensed.

[0041] Referring to Figure 3 In some embodiments, the water purification system 033 further comprises a pure water backflow control member 0031, a first end of the pure water backflow control member 0031 being communicated with the upstream of the reverse osmosis filter element 502 at the first communication node a, and a second end of the pure water backflow control member 0031 being communicated with the downstream of the reverse osmosis filter element 502 at the second communication node b, wherein the membrane filtered water can be obtained by filtering through the reverse osmosis filter element 502, and the pure water backflow control member 0031 is used to make the membrane filtered water unidirectionally flow from the downstream of the reverse osmosis filter element 502 to the upstream of the reverse osmosis filter element 502.

[0042] Optionally, the first end and the second end of the pure water backflow control member 0031 are two interfaces of the pure water backflow control member 0031, the first communication node a can have two interfaces communicated with each other, a first interface of the first communication node a being communicated with the first end of the pure water backflow control member 0031, and a second interface of the first communication node a being communicated with the first pipe opening of the reverse osmosis filter element 502, so that the first end of the pure water backflow control member 0031 is communicated with the upstream of the reverse osmosis filter element 502.

[0043] The second communication node b can have two interfaces communicated with each other, a first interface of the second communication node b being communicated with the water inlet end of the pure water backflow control member 0031, and a second interface of the second communication node b being communicated with the water outlet end of the reverse osmosis filter element 502, so that the water inlet end of the pure water backflow control member 0031 is communicated with the downstream of the reverse osmosis filter element 502, and the pure water backflow control member 0031 can be a pure water backflow unidirectional valve, the pure water backflow control member 0031 can control the membrane filtered water to be unidirectionally communicated, when the soft water purification and heating system is not working, the membrane filtered water can be controlled by the pure water backflow control member 0031 to unidirectionally flow from the downstream of the reverse osmosis filter element 502 to the upstream of the reverse osmosis filter element 502, water flow can be formed to flush the dirt on the filter membrane in the reverse osmosis filter element 502, the reverse osmosis filter element 502 can be prevented from being blocked, and the service life of the reverse osmosis filter element 502 can be prolonged.

[0044] Referring to Figure 3 In some embodiments, the water outlet end of the pure water backflow control member 0031 is communicated with the water inlet end of the reverse osmosis filter element 502 and the downstream of the pre-filter element 5011 at the first communication node a, and the water inlet end of the pure water backflow control member 0031 is communicated with the water outlet end of the reverse osmosis filter element 502 and the water inlet end of the post-filter element 5012 at the second communication node b.

[0045] Specifically, the first connecting point is a tee pipe, the first connecting point has three interfaces in communication with each other, and a first interface of the first communication node a is in communication with the water outlet end of the pure water backflow control member 0031, a second interface of the first communication node a is in communication with the water inlet end of the reverse osmosis filter element 502, and a third interface of the first communication node a is in communication with the water outlet end of the pre-filter element 5011, so that the water outlet end of the pure water backflow control member 0031 is in communication with a pipeline between an upstream of the reverse osmosis filter element 502 and a downstream of the pre-filter element 5011, and the pipeline layout between the reverse osmosis filter element 502 and the pre-filter element 5011 can be simplified.

[0046] The second connecting point is a tee pipe, the second connecting point has three interfaces in communication with each other, and a first interface of the second communication node b is in communication with the water inlet end of the pure water backflow control member 0031, a second interface of the second communication node b is in communication with the water outlet end of the reverse osmosis filter element 502, and a third interface of the second communication node b is in communication with the water inlet end of the post-filter element 5012, so that the water inlet end of the pure water backflow control member 0031 is in communication with a pipeline between a downstream of the reverse osmosis filter element 502 and an upstream of the post-filter element 5012, and the pipeline layout between the reverse osmosis filter element 502 and the post-filter element 5012 can be simplified.

[0047] Please refer to Figure 3 In some embodiments, the water purification system 003 further comprises a booster pump 70, the booster pump 70 is connected in series between the pre-filter element 5011 and the reverse osmosis filter element 502, and the booster pump 70 is located downstream of the first communication node a.

[0048] It should be noted that the water purification system is connected in series with the water softening system 002, the pre-filter element 501, the reverse osmosis filter element 502, and the post-filter element in turn, and a large number of connected processing units can reduce the water pressure inside the water purification system, especially the reverse osmosis filter element 502 needs a certain pressure to work, which leads to a higher requirement for water pressure of the water purification system.

[0049] In this embodiment, by connecting the booster pump 70 in series between the pre-filter element 5011 and the reverse osmosis filter element 502, the booster pump 70 can increase the water pressure inside the water purification system to maintain the normal operation of the soft water purification system, and the booster pump 70 is located upstream of the reverse osmosis filter element 502, so that the booster pump 70 can pressurize the reverse osmosis filter element 502 to ensure that the reverse osmosis filter element 502 can work normally.

[0050] In addition, the booster pump 70 is located downstream of the first communication node a, so that the booster pump 70, the pure water backflow control member 0031, and the reverse osmosis filter element 502 can form a loop, and when the pure water backflow control member 0031 controls the membrane filtered water to flow unidirectionally from the downstream of the reverse osmosis filter element 502 to the upstream of the reverse osmosis filter element 502, the booster pump 70 can also increase the water pressure to drive the membrane filtered water to form a water flow to flush the dirt on the filter membrane in the reverse osmosis filter element 502.

[0051] Referring to Figure 3 In some embodiments, the water purification system 003 further comprises a filtered water outlet valve 0032, which is connected in series between the pre-filter 5011 and the reverse osmosis filter 502, and is used to selectively connect the pre-filter 5011 and the reverse osmosis filter 502, and the filtered water outlet valve 0032 is located upstream of the first communication node a.

[0052] Specifically, by arranging the filtered water outlet valve 0032 between the pre-filter 5011 and the reverse osmosis filter 502, the filtered water outlet valve 0032 can control the selective connection of the pre-filter 5011 and the reverse osmosis filter 502, so that the entire water purification system can be conveniently controlled to be turned on or off. By arranging the filtered water outlet valve 0032 upstream of the first communication node a, the filtered water outlet valve 0032 will not affect the pure water backflow control member 0031 when it is closed, so that when the filtered water outlet valve 0032 is in the closed state, that is, when the water purification system is closed, the pure water backflow control member 0031 can also control the one-way flow of membrane filtered water from the downstream of the reverse osmosis filter 502 to the upstream of the reverse osmosis filter 502, so as to flush the dirt on the filter membrane in the reverse osmosis filter 502.

[0053] Referring to Figure 3 In some embodiments, the water purification system 003 further comprises a raw water quality detection member 040, which is connected in series between the pre-filter 5011 and the reverse osmosis filter 502, and is used to detect the water quality of the first filtered water flowing into the reverse osmosis filter 502, and the raw water quality detection member 040 is located downstream of the first communication node a.

[0054] It can be understood that after long-term use, the pre-filter 5011 may be damaged. By connecting the raw water quality detection member 040 in series between the pre-filter 5011 and the reverse osmosis filter 502, the raw water quality detection member 040 can detect the pre-filtered water flowing out of the pre-filter 5011. When a large number of large-particle impurities are detected in the pre-filtered water, it indicates that the pre-filter 5011 has been damaged. The raw water quality detection member 040 can issue a first warning to remind the user to replace the pre-filter 5011.

[0055] In addition, the raw water quality detection member 040 is arranged downstream of the first communication node a, so that the raw water quality detection member 040 is located between the water outlet ends of the pure water backflow control member 0031 and between the water inlet ends of the reverse osmosis filter core 502, so that when the pure water backflow control member 0031 controls the one-way flow of the membrane filtered water of the reverse osmosis filter core 502 from the downstream of the reverse osmosis filter core 502 to the upstream of the reverse osmosis filter core 502, the raw water quality detection member 040 can also detect the water quality of the membrane filtered water, and when the raw water quality detection member 040 detects that the concentration of the membrane filtered water dissolved substance is high, it can be indicated that the reverse osmosis filter core 502 has been damaged, and the raw water quality detection member 040 can issue a second warning to remind the user to replace the reverse osmosis filter core 502.

[0056] Referring to Figure 3 In some embodiments, the water purification system 003 further comprises a pure water flow control member 0033, which is located downstream of the post-filter core 5012 in the water path direction, and the pure water flow control member 0033 is used to make the pure water flow from the post-filter core 5012 to the mineral water pipeline or other pure water equipment.

[0057] It should be noted that the post-filter core 5012 is an activated carbon filter core, and if part of the pure water in contact with the external environment flows back when the water purification system 003 is closed, it may contaminate the subsequent pure water and affect the user experience.

[0058] Referring to Figure 3 In some embodiments, the water purification system 003 further comprises a pure water supply valve 0071, which is located downstream of the pure water flow control member 0033, and the water inlet end of the pure water supply valve 0071 is communicated with the water outlet end of the pre-filter core 5011 in the mineral water pipeline 007 at the third communication node c.

[0059] The third communication node is also a three-way pipe, which has three interfaces in communication with each other, wherein the first interface is communicated with the water outlet end of the pure water supply valve 0071, the second interface is communicated with the water outlet end of the pre-filter core 5011, and the third interface is communicated with the mineral water system. The pure water can be introduced into the mineral water pipeline 007 through the pure water supply valve 0071, so as to be communicated with the mineral water, and the timely supply of the mineral water is ensured.

[0060] Based on the above, in an embodiment of the present application, a domestic water solenoid valve 0072 is communicated on the mineral water pipeline 007, the water outlet end of the pre-filter core 5011 is communicated with the water inlet end of the domestic water solenoid valve 0072, and the water outlet end of the domestic water solenoid valve 0072 is communicated with the water outlet end of the pure water supply valve 0071 in the mineral water pipeline 007 at the third communication node c.

[0061] The water electromagnetic valve 0072 is also a one-way valve, which is used to one-way deliver the pre-filtered water filtered by the pre-filter 5011 to the mineral water system. In addition, since the third communication node is a three-way pipe, the pure water flowing through the pure water supply valve 0071 is prevented from flowing back to the pre-filter 5011 through the water electromagnetic valve 0072, so as to change the proportion of the pure water and the pre-filtered water entering the mineral water system, thereby affecting the water quality of the mineral water. Therefore, the water quality of the mineral water can be ensured to be suitable through the arrangement of the water electromagnetic valve 0072.

[0062] Please refer to Figure 3 In some embodiments, the water purification system 003 further comprises a water demand device, and the water inlet end of the water demand device, the water inlet end of the pure water supply valve 0071 and the water outlet end of the post-filter 5012 are communicated with the fourth communication node d.

[0063] The fourth communication node d is also a three-way pipe, which has three interfaces communicated with each other, and the first interface of the three-way pipe is communicated with the water outlet end of the post-filter 5012, the second interface is communicated with the water inlet end of the pure water supply valve 0071, and the third interface is communicated with the water inlet end of the water demand device. In this way, the pipeline layout among the pure water supply valve 0071, the post-filter 5012 and the water demand device can be simplified.

[0064] The water demand device can be the pipeline machine 006, or other pure water demand device, or the pipeline machine and other pure water demand device are connected in parallel, that is, the pipeline machine and other pure water demand device can be supplied with pure water, such as a water faucet that can be directly drunk.

[0065] Please refer to Figure 3 In some embodiments, the water purification system 003 further comprises a pure water quality detection device 0034, which is located downstream of the post-filter 5012 and upstream of the water demand device and the pure water supply valve 0071, and is used to detect the water quality of the pure water.

[0066] The pure water quality detection device 0034 can adopt a TDS (Total dissolved solids) sensor. When the TDS value of the pure water is detected to be high, the user can be reminded that the water quality of the pure water has not met the requirements, and in addition, it can be indicated that the water purification system 003 or the soft water system 002 can be damaged, so as to remind the user to detect the soft water system 002 and the water purification system 003.

[0067] Please refer to Figure 4-6 In some embodiments, the reverse osmosis filter 502 has a waste water outlet, and the waste water outlet is provided with a waste water plug 5021 for controlling the opening and closing of the waste water outlet.

[0068] It should be noted that the reverse osmosis filter element 502 produces waste water when filtering the water through the filter membrane. By providing a waste water outlet on the reverse osmosis filter element 502, and a waste water plug 5021 provided on the waste water outlet to control the opening and closing of the waste water outlet, when waste water needs to be discharged, the waste water plug 5021 can be controlled to open, so that the waste water is discharged from the reverse osmosis filter element 502, and the waste water can be conveniently discharged.

[0069] In some embodiments, referring to ​ , the water softener valve 020 includes a main valve body 021, the main valve body 021 includes an inlet raw water connector 0211 having an inlet raw water passage 0211A, an outlet raw water connector 0213 having an outlet raw water passage 0213A, and the outlet raw water connector 0213 is arranged on the inlet raw water connector 0211 to make the outlet raw water passage 0213A communicate with the inlet raw water passage 0211A. The raw water from the external raw water pipeline enters the water softener valve 020, and then passes through the inlet raw water passage 0211A and the outlet raw water passage 0213A in sequence, and is directly output from the water softener valve 020, so as to shorten the path of the raw water supplied by the water softener valve 020 as much as possible, avoid turbulent flow and pressure drop caused by multi-stage diversion, and ensure rapid supply of the raw water.
