Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
The embodiment of the present disclosure provides a three-core water purification system 10, the three-core water purification system 10 includes a pre-filter element 101, a pre-filter passage 102, a reverse osmosis filter element 103, a reverse osmosis filter passage 104, a purified water outlet 105 and a control device (not shown in fig. 1); the front filter element 101 comprises a first water inlet 10a and a first water outlet 10 b; the reverse osmosis cartridge 103 includes a second inlet 10c and a second outlet 10 d.
Wherein, the first water inlet 10a of the front filter element 101 is connected with an external water source. The first water outlet 10b of the pre-filter element 101 communicates with the second water inlet 10c of the reverse osmosis filter element 103 through the pre-filter passage 102. The second water outlet 10d of the reverse osmosis filter element 103 is communicated with the clean water outlet 105 through the reverse osmosis filtering passage 104. The pre-filter passage 102 comprises a water inlet electromagnetic valve 1021 and a booster pump 1022 which are communicated, and the water inlet electromagnetic valve 1021 and the booster pump 1022 are both connected with a control device. The reverse osmosis filtering passage 104 comprises a water storage bag 1041, a water suction pump 1042 and a pressure testing device 1043 which are communicated, and the pressure testing device 1043 and the water suction pump 1042 are both connected with a control device; the water storage bag 1041 stores first purified water which is filtered by the front filter element 101 and the reverse osmosis filter element 103 in advance;
the pressure test device 1043 is used for detecting the pressure value of the reverse osmosis filtering passage 104. The control device is used for acquiring a pressure value, and when the pressure value meets a preset condition, the control device instructs the water inlet electromagnetic valve 1021, and the booster pump 1022 and the water pump 1042 are simultaneously opened, so that the first purified water stored in the water storage bag 1041 and the second purified water filtered by the three-core water purification system 10 simultaneously flow to the purified water outlet 105.
For example, the water source may be tap water provided by a municipal administration, or may be well water or river water, which is not limited in the embodiments of the present disclosure. After the first water inlet 10a is connected to the water source, the control device may detect whether the water storage bag 1041 stores the first purified water. If not, the control device may instruct the water inlet solenoid valve 1021 and the booster pump 1022 to be turned on, at this time, the water flow of the water source enters the pre-filter 101 through the first water inlet 10a, enters the pre-filter passage 102 from the first water outlet 10b after being filtered by the pre-filter 101, is pressurized by the booster pump 1022 (because the reverse osmosis filter requires a water flow pressure of more than 0.7kg (kilogram), the water flow needs to be pressurized by the booster pump 1022), flows into the reverse osmosis filter from the second water inlet 10c, and flows into the water storage bag 1041 from the second water outlet 10d after being filtered by the reverse osmosis filter for obtaining the first purified water, and is stored, because the water pump 1042 is not turned on at this time, the first purified water may completely flow into the water storage bag 1041, and may not flow to the purified water outlet 105 through the reverse osmosis.
If the first purified water is stored in the water storage bag 1041, the control device may obtain the pressure value of the reverse osmosis filtration path 104 detected by the pressure testing device 1043 in real time. Specifically, when the user needs water, the user can take water from the purified water outlet 105, and the purified water outlet 105 can be provided with a faucet. When the user takes water, the water pressure of the reverse osmosis filtration path 104 is lowered, that is, the pressure value detected by the pressure test device 1043 is lowered. The control means may determine in real time whether the pressure value is less than or equal to a preset threshold value. If not, it indicates that the user does not take water, and the three-core water purification system 10 can keep the current state unchanged. If yes, it indicates that the user is getting water, at this time, the control device may instruct the water inlet solenoid valve 1021, the booster pump 1022 and the water pump 1042 to be simultaneously opened, the water pump 1042 pumps the first purified water stored in the water storage bag 1041, and at the same time, the water inlet solenoid valve 1021, and after the booster pump 1022 is opened, the pre-filter 101 and the reverse osmosis filter 103 start to make water, that is, the second purified water obtained by filtering through the pre-filter 101 and the reverse osmosis filter 103 while pumping the first purified water may also flow to the purified water outlet 105 through the reverse osmosis filtering passage 104, that is, the water obtained by the user at the purified water outlet 105 is a mixed water of the first purified water and the second purified water, so as to avoid a problem of a higher TDS (Total dissolved solids) value of the first cup of water caused by long-term non-water taking; meanwhile, since the water pump 1042, the front filter element 101 and the reverse osmosis filter element 103 work simultaneously, the water flow at the water purification outlet 105 is relatively large, for example, if the water production speed of the three-element water purification system 10 is about 0.5L/min (liter/min), the volume of the water storage bag 1041 is 3 liters, and the water pumping speed of the water pump 1042 is 1.5L/min, then when a user takes water, the water purification system can continuously output about 4L of water within 2 minutes at a speed of 2.0L/min, which can satisfy most water usage scenarios, and the user experience is better.
Alternatively, the reservoir bag 1041 may be made of TPU (Thermoplastic polyurethane elastomers). Preferably, the reservoir bag 1041 has a volume of 3 liters.
In the technical solution provided by the embodiment of the present disclosure, when it is detected that the pressure value of the reverse osmosis filtration passage 104 is decreased, the water inlet solenoid valve 1021, the booster pump 1022 and the water pump 1042 of the three-core water purification system 10 may be simultaneously opened, so that the first purified water pre-stored in the water storage bag 1041 and the second purified water filtered by the three-core water purification system 10 simultaneously flow to the purified water outlet 105, thereby increasing the water flow rate of the purified water outlet 105; meanwhile, the water storage bag 1041 is used for storing purified water, the cost of the whole three-core water purification system 10 is reduced, the popularization and the use of the water purifier are facilitated, and the volume of the water storage bag 1041 for storing purified water is small, so that the volume of the whole three-core water purification system 10 is reduced, and the condition that too much space is occupied under a kitchen is avoided.
In one embodiment, as shown in fig. 2, the reverse osmosis filtration circuit 104 further comprises a bypass 1044. One end of the branch passage 1044 is communicated with the second water outlet 10d of the reverse osmosis filter element 103, and the other end is communicated with the purified water outlet 105.
For example, if the first purified water stored in the water storage bag 1041 and the second purified water filtered by the front filter element 101 and the reverse osmosis filter element 103 need to be pumped by the water pump 1042, the pumping force of the water pump 1042 needs to be larger, and the price of the water pump 1042 is higher when the pumping force is larger, so that it is difficult to reduce the hardware cost of the whole three-core water purification system 10 by using the water pump 1042 with large pumping force. In the embodiment of the present disclosure, a branch passage 1044 is disposed in the reverse osmosis filtration passage 104, one end of the branch passage 1044 is communicated with the second water outlet 10d of the reverse osmosis filter element 103, and the other end is communicated with the purified water outlet 105, that is, the second purified water filtered by the pre-filter element 101 and the reverse osmosis filter element 103 in sequence does not need to be pumped by the water pump 1042, and can directly flow from the second water outlet 10d to the purified water outlet 105 through the branch passage 1044. Because the water pump 1042 only needs to pump the first purified water stored in the water storage bag 1041, and the requirement on the pumping capacity is not high, the three-core water purification system 10 can select a low-value water pump with a small pumping capacity, so that the hardware cost of the whole three-core water purification system is reduced, and the popularization and the use of the water purification system are facilitated.
In one embodiment, as shown in fig. 3, the three-core water purification system 10 further comprises a post-filter cartridge 106 and a post-filter passage 107; the rear cartridge 106 includes a third inlet 10e and a third outlet 10 f.
Wherein, the second water outlet 10d of the reverse osmosis filter element 103 is communicated with the third water inlet 10e of the post-filter element 106 through the reverse osmosis filtering passage 104. The third water outlet 10f of the post-filter element 106 communicates with the clean water outlet 105 through the post-filter passage 107.
For example, the water filtered by the front filter element and the reverse osmosis filter element can flow into the rear filter element 106 again through the third water inlet 10e, and then flows to the purified water outlet 105 through the rear filter passage 107 after being filtered by the rear filter element 106.
Specifically, the user can take water from the purified water outlet 105 when the user needs the water. When the user takes water, the water pressure of the reverse osmosis filtration path 104 is lowered, that is, the pressure value detected by the pressure test device 1043 is lowered. The control means may determine in real time whether the pressure value is less than or equal to a preset threshold value. If not, it indicates that the user does not take water, and the three-core water purification system 10 can keep the current state unchanged. If yes, it means that the user is getting water, at this time, the control device may instruct the water inlet solenoid valve 1021, the booster pump 1022 and the water pump 1042 to be simultaneously opened, the water pump 1042 pumps the first clean water stored in the water storage bag 1041, the water inlet solenoid valve 1021, and after the booster pump 1022 is opened, the front filter 101 and the reverse osmosis filter start to operate, that is, the water sequentially filtered by the front filter 101 and the reverse osmosis filter 103 while pumping the first clean water may also enter the reverse osmosis filtering path 104, flows into the rear filter 106 from the third water inlet 10e after being mixed in the reverse osmosis filtering path 104, and flows to the clean water outlet 105 through the rear filtering path 107 after being filtered by the rear filter 106, that is, at this time, the water flowing out from the clean water outlet 105 is the water after being filtered by the rear filter 106 of the first clean water stored in the water storage bag 1041, and sequentially flows through the front filter 101, the, The reverse osmosis filter element 103 and the post filter element 106 are used for filtering the second purified water and mixing the second purified water. If the pressure value obtained by the control device returns to normal again, it indicates that the user has finished taking water, and at this time, the control device may instruct the water inlet solenoid valve 1021, the booster pump 1022 and the water pump 1042 to turn off.
As can be seen from the above description, firstly, the water obtained by the purified water outlet 105 is mixed water, so that the TDS value of the first cup of water flowing out from the purified water outlet 105 when the water is not used for a long time is reduced; secondly, since the water pump 1042 and the three-core water purification system work simultaneously, the water flow at the water purification outlet 105 is relatively large, for example, if the water production speed of the three-core water purification system 10 is about 0.5L/min, the volume of the water storage bag 1041 is 3 liters, and the water pumping speed of the water pump 1042 is 1.5L/min, then when a user takes water, the water purification system can continuously output 4L of water within 2 minutes at a speed of 2.0L/min, which can satisfy most water usage scenarios, and the user experience is better; thirdly, because the three-core water purification system 10 can reach the water outlet speed with large flux on the basis of small flux, a power adapter, a booster pump, a filter element and the like with small volume can be selected, namely, the water outlet with large flux is realized at an economical and applicable price, and the cost of the whole three-core water purification system 10 is further reduced. Fourthly, the manufacturing cost of the water storage bag is far less than that of the pressure tank, so that the hardware cost of the whole three-core water purification system is reduced by adopting the water storage bag to store the first purified water, and the popularization and the use of the water purification system are facilitated; fifthly, the water storage bag in the three-core water purification system has small volume and small water storage capacity, so that the water can be stored quickly and is not easy to breed bacteria; sixth, since the reservoir bag 1041 does not require compressed air as compared to the pressure tank, a large amount of storage is achieved with a small amount, for example, a spatial pressure tank with a capacity of 3L, only 1.5L of water can be stored due to the compressed air, and a reservoir bag with a capacity of 3L can store up to 3L of water, thereby improving space utilization; seventhly, the water storage bag 1041 can be installed inside the water purifier, and an additional water storage pressure tank or water storage bag does not need to be arranged outside the main machine of the water purifier, so that the volume of the water purifier is reduced; eighth, if the water production speed of the three-core water purification system 10 is about 0.5L/Min and the capacity of the water storage bag 1041 is 3L, the three-core water purification system 10 can produce the water storage bag in about 6 minutes, and the conventional small-flux water purifier generally needs about 10-15 Min to produce the water storage bag arranged outside the water storage bag, so that the interval time for continuously using the three-core water purification system 10 is shortened, and the utilization rate of the three-core water purification system 10 is improved.
Optionally, the front filter element 101 may be a PP and carbon rod composite filter element, and may also be referred to as a PCB composite filter element; wherein the PP is a synthetic chemical fiber made of polypropylene fiber. This PCB composite filter core can filter the large granule impurity and some coloured impurity of aquatic, avoids the impurity damage of aquatic to intake original papers such as solenoid valve 1021, booster pump 1022 and reverse osmosis filter core to effectively improve this water purification system's life. The post-filter 106 may be an activated carbon filter disposed at the final position of the purified water passage for further filtering the purified water flowing therethrough, and adding metal ions for enhancing taste, such as ferrous iron ions or magnesium ions. In practical application, other filter elements can be replaced according to specific situations, and the embodiment of the disclosure does not limit the filter elements.
Optionally, the pressure testing device 1043 may be a high-voltage switch, and when it is detected that the pressure value is smaller than or equal to the preset threshold, a signal is sent to the control device, so that the control device can instruct the water inlet solenoid valve 1021, the booster pump 1022, and the water pump 1042 to be turned on simultaneously.
In the present disclosure, when a user takes water, the pressure in the reverse osmosis filtering path 104 decreases, the high-voltage switch closes the conductive loop, and the control device finds that the conductive loop is closed, and then controls the water inlet solenoid valve 1021, the booster pump 1022 and the water pump 1042 to open simultaneously, that is, to start pumping water and producing water simultaneously, so that the first purified water and the second purified water flow to the purified water outlet 105 simultaneously. When the user stops taking water, the pressure in the reverse osmosis filtering passage 104 returns to a larger state, the high-voltage switch disconnects the conductive loop, and the control device detects that the conductive loop is disconnected, and then controls the water inlet electromagnetic valve 1021, the booster pump 1022 and the water suction pump 1042 to be closed, so as to stop pumping water and producing water.
In one embodiment, referring to fig. 1, 2 and 3, the three-core water purification system 10 further comprises a waste water passage 108 and a waste water outlet 109. The reverse osmosis filter element 103 is provided with a waste water outlet 10 g. The waste water outlet 10g is connected to a waste water passage 108 for flowing the waste water generated by the reverse osmosis filter element 103 to a waste water outlet 109 through the waste water passage 108.
Illustratively, wastewater is produced when water is produced by the reverse osmosis cartridge 103. Meanwhile, in order to ensure the filtering effect, the three-core water purification system 10 also needs to periodically flush the reverse osmosis filter element 103, and waste water is also generated during flushing. In order to facilitate the rapid discharge of the two types of wastewater, a wastewater passage 108 may be provided, the wastewater passage 108 is connected to the wastewater outlet 10g of the reverse osmosis filter element 103, and a wastewater solenoid valve 1081 connected to the control device and in a normally closed state is provided, and a water through hole is provided on the wastewater solenoid valve 1081. When the waste water electromagnetic valve 1081 is closed, the diameter of the water passing through hole is smaller; when the waste water solenoid valve 1081 is opened, the diameter of the water passing through hole is large. In practical application, the specific size of the water through hole can be selected according to the water purification capacity of the reverse osmosis filter element 103, that is, the higher the water purification capacity of the reverse osmosis filter element 103 is, the smaller the aperture of the water through hole when the waste water solenoid valve 1081 is closed is.
Normally, the waste water solenoid valve 1081 is normally closed, and waste water produced by normal water production in the reverse osmosis filter element 103 flows into the waste water passage 108 through the waste water outlet 10g, and then flows to the waste water outlet 109 through the water passing hole with a small diameter. Meanwhile, the diameter of the water through hole is small, so that the pressurizing effect of the pressurizing pump 1022 is not affected. When the control device determines that the reverse osmosis filter element 103 needs to be flushed, the control device indicates that the wastewater solenoid valve 1081 is opened, the water inlet solenoid valve 1021 and the booster pump 1022 are opened, and the water suction pump 1042 is closed, so that after sewage generated after the reverse osmosis filter element 103 is flushed by water flows into the wastewater passage 108 through the wastewater outlet 10g, the sewage can flow to the wastewater outlet 109 through the water passing through hole with the larger diameter of the wastewater solenoid valve 1081.
Optionally, the reverse osmosis filtering path 104 further includes a check valve 1045, and the check valve 1045 is disposed between the reverse osmosis filter element 103 and the pressure testing device 1043, and is configured to maintain the pressure of the reverse osmosis filtering path 104 when the waste water solenoid valve 1081 is opened.
If the check valve 1045 is not provided, when the reverse osmosis filter element 103 is flushed, since the diameter of the water passing hole is larger after the waste water solenoid valve 1081 is opened, the water flow in the whole purified water passage can flow to the waste water outlet 109 through the water passing hole, which inevitably causes the water pressure of the reverse osmosis filtration passage 104 to be reduced. If the pressure testing device 1043 detects a decrease in pressure and sends a signal to the control device, it may cause the control device to make a false determination that the user is fetching water. In order to avoid the above situation, a check valve 1045 may be provided between the reverse osmosis filter element 103 and the pressure testing device 1043, that is, water is allowed to flow from the reverse osmosis filter element 103 to the pressure testing device 1043, and water is prohibited to flow from the reverse osmosis filter element 103 to the pressure testing device 1043, so that even if the diameter of the water through hole is large after the waste water solenoid valve 1081 is opened, the water pressure of the reverse osmosis filtration passage 104 is not changed, and the erroneous judgment of the control device is avoided.
The embodiment of the present disclosure provides a three-core water purification system 10, when it is detected that the pressure value of the reverse osmosis filtration path 104 is decreased, the water inlet solenoid valve 1021, the booster pump 1022 and the water pump 1042 of the three-core water purification system 10 may be simultaneously opened, so that the first purified water pre-stored in the water storage bag 1041 and the second purified water filtered by the three-core water purification system 10 simultaneously flow to the purified water outlet 105, thereby increasing the water flow rate of the purified water outlet 105; meanwhile, the water storage bag 1041 is used for storing purified water, the cost of the whole three-core water purification system 10 is reduced, the popularization and the use of the water purifier are facilitated, and the volume of the water storage bag 1041 for storing purified water is small, so that the volume of the whole three-core water purification system 10 is reduced, and the condition that too much space is occupied under a kitchen is avoided.
According to the embodiment of the present disclosure, a three-core water purifier is provided, which includes the three-core water purifying system 10 of any one of the above embodiments and a casing for wrapping the three-core water purifying system 10. When a user takes water, the water inlet electromagnetic valve 1021, the booster pump 1022 and the water pump 1042 of the three-core water purification system 10 can be simultaneously opened, so that the first purified water pre-stored in the water storage bag 1041 and the second purified water filtered by the three-core water purification system 10 simultaneously flow to the purified water outlet 105, and the water flow speed of the purified water outlet 105 is increased; meanwhile, the water storage bag 1041 is used for storing purified water, the cost of the whole three-core water purification system 10 is reduced, the popularization and the use of the water purifier are facilitated, and the volume of the water storage bag 1041 for storing purified water is small, so that the volume of the whole three-core water purification system 10 is reduced, and the condition that too much space is occupied under a kitchen is avoided.
It should be noted that, since the three-core water purifier adopts all the technical solutions of all the embodiments, all the beneficial effects brought by the technical solutions of the embodiments are also achieved, and are not described in detail herein.
