Description

Water purifier
Technical Field
The present invention relates to a water purifier, and more particularly, to a water purifier capable of purifying raw water (or tap water) in two stages. Furthermore, the water purifier can control raw water to carry out back flushing on the primary filter element.
Background
With the increasing improvement of living standard and the increasing emphasis on health, the quality requirement of people on domestic water is higher and higher. On the other hand, however, many countries, especially developing countries, have increasingly serious water pollution problems with the continuous development of agriculture and industry, which inevitably leads to the water source of domestic water, especially tap water, being affected either lightly or heavily. In addition, the quality of tap water is affected by the external environment and water supply pipelines. For example, the water source of tap water has an increased sand content, which leads to a deterioration of the quality of the tap water. The quality of tap water can be influenced by lack of cleaning and aging of a tap water supply pipe network for a long time. Thus, in many cases, tap water is not suitable for direct drinking. In order to solve the above problems of the tap water, various household water purification apparatuses, such as an ultrafiltration water purifier, an RO membrane water purifier, a pre-filter, and the like, have appeared on the market to purify the tap water. Among these water purification units, faucet water purifiers are popular with many consumers because of their advantages of small size, convenient assembly and disassembly, and the ability to automatically purify tap water under tap water pressure without the need of electric power. However, the existing faucet water purifier also has a plurality of defects. First, most faucet water purifiers currently use only a single purifying filter element, such as a ceramic filter element, an activated carbon filter element, or an ultrafiltration filter element, to purify tap water. The tap water purifier using the single ceramic filter element or the single activated carbon filter element has large aperture of the ceramic filter element or the activated carbon filter element, so that tap water is not thoroughly purified, and the obtained purified water is not suitable for direct drinking. The tap water purifier which purifies tap water by using the single ultrafiltration filter element is very easy to block and cause the tap water purifier to be very unusable due to the small aperture of the ultrafiltration filter element. Especially under the condition of poor water quality, the ultrafiltration filter element is easy to block.
The chinese patent application No. 201811199228.2 discloses a tap water purifier for purifying tap water by using micro-filtration ceramic, activated carbon and ultra-filtration ceramic, wherein when the tap water purifier is used for treating tap water, the micro-filtration ceramic is firstly used for carrying out micro-filtration on the tap water, then the activated carbon is used for carrying out activated carbon filtration on purified water generated by the micro-filtration ceramic, and then the purified water generated by the activated carbon is further filtered by the ultra-filtration ceramic to generate ultra-filtration purified water. However, the faucet water purifier disclosed in this patent lacks a flushing mechanism, and particularly lacks a mechanism for flushing the micro-filtration ceramic and the ultra-filtration ceramic, which results in a very short time period for a large amount of impurities and microorganisms to accumulate on the surfaces of the micro-filtration ceramic and the ultra-filtration ceramic membrane, and clog the micro-filtration ceramic and the ultra-filtration ceramic membrane. Even more, the accumulation of a large number of microorganisms causes the faucet water purifier provided by the patent of the invention to be likely to smell after being used for a short time. And finally, the water inlet of the faucet water purifier is communicated with the water outlet of the faucet. In other words, the water supply and treatment of the faucet water purifier are controlled by the faucet switch, not by the faucet water purifier itself. This makes it difficult for the faucet water purifier to perform functions other than water treatment such as filtration. For example, the control regulates the flow rate of raw water flowing through and treated by the faucet water purifier.
The application number is 201220080023.4's chinese utility model patent application discloses an utilize pottery and ultrafiltration filter core to carry out two-stage purification treatment's leading water purifier to the running water, wherein this one-level filter core of this leading water purifier can carry out preliminary purification to the running water, and its second grade filter core further purifies the purification water that the one-level filter core generated. However, this utility model patent application provides this tap water purifier both lacks the mechanism that washes the one-level filter core, also lacks the mechanism that washs (or washes) the second grade filter core, leads to this utility model patent application to provide a tap water purifier also can use very short time will stink. And finally, the water inlet of the faucet water purifier is communicated with the water outlet of the faucet. In other words, the water supply and treatment of the faucet water purifier are also controlled by the faucet switch, not by the faucet water purifier itself. This makes it difficult for the faucet water purifier to perform functions other than water treatment such as filtration. For example, the control regulates the flow rate of raw water flowing through and treated by the faucet water purifier.

Preferably, the secondary filter element 23K of the filtering means 20K of the water purifier 2 of the present invention is an external pressure type ultrafiltration filter element. Correspondingly, each ultrafiltration membrane wire 231K of the secondary filter element 23K forms a membrane wire channel 2310K, and the membrane wire channels 2310K of the ultrafiltration membrane wires 231K are communicated with the purified water outlet 2301K of the secondary filter element 23K, so that the purified water generated by each ultrafiltration membrane wire 231K of the secondary filter element 23K can flow to the third communication opening 203K of the filtering device 20K under the action of water pressure.
As shown in fig. 1A, 2B to 4D and 10A to 10B of the drawings, accordingly, when the filter device 20K of the water purifier 2 according to the first embodiment of the present invention is used for treating raw water, a user can control the raw water to flow to the first communication opening 201K of the filter device 20K through the control valve 10K, the raw water flows to the raw water passage 2101K of the filter device 20K under the action of water pressure, the raw water is treated by the primary filter element 22K under the action of water pressure, and the produced purified water flows to the purified water passage 2201K, at this time, if the purified water in the purified water passage 2201K cannot freely flow through the second communication opening 202K of the filter device 20K under the control of the control valve 10K, and the purified water produced by the secondary filter element 23K can freely flow to the third communication opening 203K, the purified water produced by the primary filter element 22K will be under the action of water pressure, further purified by the secondary filter element 23K, the purified water produced by the secondary filter element 23K is discharged from the third communication opening 203K and supplied. Accordingly, the water purifier 2 according to the first embodiment of the present invention is now in a first purification operation state. On the other hand, if the purified water in the purified water passage 2201K can freely flow through the second communication opening 202K of the filter device 20K under the control of the control valve 10K, and the purified water generated by the secondary filter element 23K cannot freely flow to the third communication opening 203K, the purified water generated by the primary filter element 22K will flow out from the second communication opening 202K and be supplied under the action of the water pressure. Accordingly, the water purifier 2 according to the first embodiment of the present invention is now in a second purification operation state.
As shown in fig. 1A, 2B to 4D and 10D of the drawings, the water purifier 2 according to the first embodiment of the present invention further has a back-flushing operation state, wherein when the water purifier 2 of the present invention is in the back-flushing operation state, a user can control raw water to flow to the second communication opening 202K of the filtering device 20K through the control valve 10K, raw water flows from the second communication opening 202K to the water purifying passage 2201K of the filtering device 20K under the action of water pressure, at this time, under the control of the control valve 10K, purified water generated by the secondary filter element 23K cannot flow freely to the third communication opening 203K, raw water in the water purifying passage 2201K back-flushes the primary filter element 22K under the action of water pressure, generated sewage flows from the raw water passage 2101K to the first communication opening 201K of the filtering device 20K under the action of water pressure, and flows out from the first communication opening 201K under the control of the control valve 10K. It should be understood that the term "back flushing" as used herein refers to the flow direction of raw water flowing through the primary filter element 22K when the primary filter element 22K is flushed, and the flow direction of raw water flowing through the primary filter element 22K when the primary filter element 22K purifies raw water.
As shown in fig. 10C of the drawings, the water purifier 2 according to the first embodiment of the present invention further has a standby operation state, wherein when the water purifier 2 is in the standby operation state, a user can control the raw water not to flow to the filtering device 20K through the control valve 10K.
It is worth noting that, when the second-stage filter element 23K of the filtering device 20K of the water purifier 2 of the present invention is an external pressure type ultrafiltration filter element, and the purified water generated by the first-stage filter element 22K can freely flow out from the second communication opening 202K of the filtering device 20K, and the purified water generated by the first-stage filter element 22K flows out through the second communication opening 202K of the filtering device 20K, the purified water generated by the first-stage filter element 22K will flow through the ultrafiltration membrane wire 231K of the second-stage filter element 23K, so that the ultrafiltration membrane wire 231K of the second-stage filter element 23K is washed by the purified water generated by the first-stage filter element 22K. In other words, at this time, the filter device 20K of the water purifier 2 of the present invention allows the ultrafiltration membrane wires 231K of the secondary filter element 23K to be further cleaned with the purified water produced by the primary filter element 22K while supplying the purified water produced by the primary filter element 22K. As known to those skilled in the art, a faucet water purifier directly installed in a faucet has a small volume due to the limitation of a use space where the faucet water purifier is located. When the tap water purifier utilizes the ultrafiltration filter element, particularly the ultrafiltration filter element which takes the ultrafiltration membrane wire as the main filter element, the ultrafiltration filter element is easy to stink and cannot be used continuously because of the accumulation of tap water impurities, such as microorganisms and other impurities, attached to the surface of the ultrafiltration membrane wire. The filter device 20K of the water purifier 2 of the present invention allows the purified water produced by the primary filter element 22K to be supplied, and also allows the surface of the ultrafiltration membrane wire 231K of the secondary filter element 23K to be cleaned by the purified water produced by the primary filter element 22K, thereby preventing impurities such as microorganisms in the tap water from being accumulated in the secondary filter element 23K and preventing the impurities from being smelled and being unable to be used continuously. In other words, the water purifier 2 solves the problem that the traditional faucet water purifier is easy to generate impurity accumulation and cannot be discharged in time to cause odor when the traditional faucet water purifier uses an ultrafiltration filter element (or an ultrafiltration membrane wire) to filter water through the ingenious structural design of the filtering device 20K, so that the ultrafiltration membrane wire 231K of the secondary filter element 23K has a better filtering effect and the service life of the secondary filter element 23K is prolonged. More importantly, because the faucet water purifier has smaller volume, with the structure of the traditional faucet water purifier, when the ultrafiltration filter element is used for treating raw water such as tap water, blockage can occur in a short time. When the water purifier 2 utilizes the purified water generated by the first-stage filter element 22K, the flushing effect of the ultrafiltration membrane wire 231K of the second-stage filter element 23K obviously improves the problem that impurities are gathered and cannot be discharged in time when the traditional tap water purifier uses the ultrafiltration filter element (or ultrafiltration membrane wire) to filter water, so that the tap water purifier can filter water by using the ultrafiltration filter element. The greater significance of the water purifier 2 of the present invention is the potential for consumers to get rid of the bulky, expensive traditional desktop water purifiers. In addition, since the first-stage filter element 22K of the water purifier 2 of the present invention is preferably a ceramic filter element, the purified water produced by the filtration is not suitable for direct drinking, but is subjected to preliminary filtration and purification treatment, and can be used for washing vegetables, washing, etc.

It can be understood that the distribution of the first, second, third, fourth, fifth and eighth passages 101K, 102K, 103K, 104K, 105K and 108K of the planar valve 10K of the water purifier 2 according to the first embodiment of the present invention at the first fluid control surface 1210K of the fixed valve plate 121K of the planar valve 10K, so that when the movable valve plate 122K of the flat valve 10K of the water purifier 2 rotates relative to the fixed valve plate 121K, so that when the flat valve 10K is switched from the standby operating position to the first purge operating position (or from the first purge operating position to the standby operating position), or is switched from the standby operating position to the second purge operating position (or from the second purge operating position to the standby operating position), even if the working position is not completely switched (or during switching), the movable valve plate 122K of the flat valve 10K can rotate relative to the fixed valve plate 121K to achieve stable conduction of the flow passage. The main reason is that when the flat valve 10K is switched from the standby operating position to the first purge operating position or from the first purge operating position to the standby operating position, during the switching process, the sixth channel 106K of the flat valve 10K is always in stable communication with only the first channel 101K, and the seventh channel 107K of the flat valve 10K is always in stable communication with only the fourth channel 104K and the fifth channel 105K, respectively; when the flat valve 10K is switched from the standby operating position to the second purge operating position or from the second purge operating position to the standby operating position, during the switching process, the sixth channel 106K of the flat valve 10 is always in stable communication with only the eighth channel 108K, and the seventh channel 107K of the flat valve 10K is always in stable communication with only the second channel 102K and the third channel 103K, respectively. The sixth channel 106K of the flat valve 10K is always in stable communication only with the first channel 101K, the seventh channel 107K of the flat valve 10K is always in stable communication only with the fourth channel 104K and the fifth channel 105K respectively, and the sixth channel 106K of the flat valve 10 are always in stable communication only with the eighth channel 108K, the seventh channel 107K of the flat valve 10K is always in stable communication with only the second channel 102K and the third channel 103K, respectively, ensuring that when the flat valve 10K is switched from the standby operating position to the first purge operating position or from the first purge operating position to the standby operating position, and when switching from the standby working position to the second purge working position or from the second purge working position to the standby working position, no streaming occurs, thereby ensuring stepless control of the flow rate of the water flow through the control valve 10K during station switching.
As shown in fig. 11A to 12F of the drawings, it should be noted that when a user needs to switch the water purifier 2 according to the first embodiment of the present invention from the back-flushing operation state to the second cleaning operation state, the user only needs to rotate the movable valve plate 122K of the flat valve 10K counterclockwise by an equal angle, so that the first area 2001K of the second fluid control surface 1220K of the movable valve plate 122K faces the third portion 1203K of the first fluid control surface 1210K of the fixed valve plate 121K; when the user needs to switch the water purifier 2 from the second purification operating state to the standby operating state according to the first embodiment of the present invention, the user only needs to rotate the movable valve plate 122K of the planar valve 10K counterclockwise again by an equal division angle, so that the first area 2001K of the second fluid control surface 1220K of the movable valve plate 122K faces the second portion 1202K of the first fluid control surface 1210K of the fixed valve plate 121K; when the user needs to switch the water purifier 2 from the standby operation state to the first purification operation state according to the first embodiment of the present invention, the user only needs to rotate the movable valve plate 122K of the planar valve 10K counterclockwise by an equal division angle again, so that the first area 2001K of the second fluid control surface 1220K of the movable valve plate 122K faces the first portion 1201K of the first fluid control surface 1210K of the fixed valve plate 121K. In other words, the structure of the planar valve 10K of the water purifier 2 according to the present invention enables four operation states of the back flush operation state, the second purification operation state, the standby operation state and the first purification operation state of the water purifier 2 to be continuously distributed, so that the complete switching among the adjacent operation states of the back flush operation state, the second purification operation state, the standby operation state and the first purification operation state of the water purifier 2 according to the present invention can be realized only by rotating the movable valve plate 122K of the planar valve 10K by an equal division angle. The switching manner among the four working states of the water purifier 2 determined by the structure of the plane valve 10K of the water purifier 2 of the invention enables the switching among the four working states of the water purifier 2 of the invention to be more in line with the use habits of users and to be difficult to cause the working states to be switched wrongly due to different rotating angles when the users switch among the working states. It can be understood that, since the extension portion 12102K and the edge portion 12103K of the first fluid control surface 1210K of the planar valve 10K of the water purifier 2 according to the first embodiment of the present invention are equally divided, and the extension area 12202K and the edge area 12203K of the second fluid control surface 1220K of the movable valve plate 122K of the planar valve 10K are equally divided, accordingly, the water purifier 2 according to the present invention rotates the movable valve plate 122K of the planar valve 10K by 90 degrees every time an operation state is switched. In other words, an angle of bisection between the movable valve plate 122K and the fixed valve plate 121K of the planar valve 10K is 90 degrees. Optionally, the extension portion 12102K and the edge portion 12103K of the first fluid control surface 1210K are equally divided into the first portion 1201K, the second portion 1202K, the third portion 1203K and the fourth portion 1204K counterclockwise, and the extension area 12202K and the edge area 12203K of the second fluid control surface 1220K of the movable valve plate 122K of the planar valve 10K are equally divided into the first area 2001K, the second area 2002K, the third area 2003K and the fourth area 2004K counterclockwise. At this time, the structure of the flat valve 10K of the water purifier 2 according to the present invention continuously distributes four working states of the first purification working state, the standby working state, the second purification working state and the backwash working state of the water purifier 2, so that the switching between the adjacent working states of the first purification working state, the standby working state, the second purification working state and the backwash working state of the water purifier 2 according to the present invention can be realized only by rotating the movable valve plate 122K of the flat valve 10K by an equal division angle. In addition, as described above, when the water purifier 2 according to the first embodiment of the present invention is switched from the standby operation state to the first purification operation state (or the second purification operation state), the stepless control of the flow rates of the inlet water and the outlet water of the water purifier 2 according to the present invention can be realized by adjusting the overlapping degree of the passages (the sixth passage 106K and the seventh passage 107K) of the movable valve plate 122K and the passages (the first passage 101K, the second passage 102K, the third passage 103K, the fourth passage 104K, the fifth passage 105K and the eighth passage 108K) of the fixed valve plate 121K. However, when the water purifier 2 of the present invention is switched from the standby operation state to the first purification operation state (or the second purification operation state), the sixth channel 106K of the movable valve plate 122K is directly opposite to the first channel 101K (or the eighth channel 108K) of the fixed valve plate 121 by rotating the movable valve plate 122K through an equal division angle, and the seventh channel 107K is directly opposite to the fourth channel 104K and the fifth channel 105K (or the second channel 102K and the third channel 103K), so as to implement the state switching. At this time, the flow rates of the inlet water and the outlet water of the water purifier 2 according to the present invention are maximized. It is understood that the water purifier 2 can also be switched from the first purification operation state to the standby operation state (or from the second purification operation state to the standby operation state) quickly by rotating an equal division angle.

Wherein when the movable valve plate 122T of the planar valve 10T is rotated to the position where the first partition (the first region 2001T) of the second fluid control surface 1220T of the movable valve plate 122T faces the first partition (the first portion 1201T) of the first fluid control surface 1210T of the fixed valve plate 121T, the third partition (the third region 2003T) of the second fluid control surface 1220T of the movable valve plate 122T of the planar valve 10T faces the third partition (the third portion 1203T) of the first fluid control surface 1210T of the fixed valve plate 121T, such that the sixth channel 106T of the planar valve 10T is respectively communicated with the raw water inlet channel 1012T and the first channel 101T, and the seventh channel 107T is respectively communicated with the fourth channel 104T and the fifth channel 105T, so as to allow raw water to flow from the raw water inlet 1106K, the raw water inlet channel 1012T, the sixth channel 106T, and the fifth channel 105T, The first passage 101T, the first opening 1101K, and the first communication opening 201K flow into the filtering device 20K, after the raw water is filtered by the primary filter element 22K of the filtering device 20K, the generated purified water flows into the purified water passage 2201K of the filtering device 20K, the purified water generated by the primary filter element 22K further flows out from the third communication opening 203K through the purified water outlet 2301K, and then flows out and is provided through the fourth opening 1104K, the fourth passage 104T, the seventh passage 107T, the fifth passage 105T, and the fifth opening 1105K, where correspondingly, the water purifier 2 is in the first purification working state at this time.
As shown in fig. 26A to 27F of the drawings, preferably, the fourth channel 104T and the fifth channel 105T extend along the first fluid control surface 1210T, the extending direction of the fourth channel 104T is the same as that of the fifth channel 105T, and the sixth channel 106T corresponds to that of the seventh channel 107T, so that when the flat valve 10T is switched from the standby operating position to the first purification operating position, the movable valve plate 122T of the flat valve 10T is rotated to a state where the sixth channel 106T coincides with the raw water inlet channel 1012T and the first channel 101T, and the seventh channel 107T coincides with the fourth channel 104T and the fifth channel 105T at the same time; and switching the flat valve 10T from the standby operating position to the second purification operating position, wherein the movable valve plate 122T of the flat valve 10T is rotated until the seventh channel 107T coincides with the second channel 102T and the third channel 103T at the same time when the sixth channel 106T coincides with the raw water inlet channel 1012T and the eighth channel 108T. Accordingly, when the flat valve 10T is switched from the standby position to the first purification position (or from the first purification position to the standby position), the user can control the flow rate of the raw water flowing to the filter device 20K by adjusting the overlapping degree of the sixth channel 106T and the first channel 101T. Further, the second channel 102T and the third channel 103T extend along the first fluid control surface 1210T, and the extending directions of the second channel 102T and the third channel 103T are the same, so that when the planar valve 10T is switched from the standby operating position to the second purification operating position (or from the second purification operating position to the standby operating position), a user can control the flow rate of raw water flowing to the filtering device 20K by adjusting the overlapping degree of the sixth channel 106T and the eighth channel 108T. Accordingly, the fourth channel 104T corresponds to the fifth channel 105T, and the second channel 102T corresponds to the third channel 103T. It can be understood that when the user adjusts the degree of coincidence of the sixth channel 106T with the first channel 101T, the degree of coincidence of the seventh channel 107T with the fourth channel 104T (and the fifth channel 105T) is adjusted accordingly; when the user adjusts the overlapping degree of the sixth channel 106T and the eighth channel 108T, the overlapping degree of the seventh channel 107T and the second channel 102T (and the third channel 103T) is also adjusted accordingly. Therefore, the user can adjust the inflow and outflow of the water purifier 2 according to the first embodiment of the present invention, thereby achieving a stepless flow rate control of the water purifier 2 according to the first embodiment of the present invention. In other words, when the planar valve 10T is switched from the standby operating position to the first purification operating position or from the standby operating position to the second purification operating position, the movable valve plate 122T can be rotated around the center of the movable valve plate 122T to adjust the overlapping degree of the passages of the movable valve plate 122T (the sixth passage 106T and the seventh passage 107T) and the passages of the fixed valve plate 121T (the first passage 101T, the second passage 102T, the third passage 103T, the fourth passage 104T, the fifth passage 105T and the eighth passage 108T), so as to achieve the stepless flow control of the inlet water and the outlet water of the water purifier 2.

More preferably, the first channel 101T, the second channel 102T, the third channel 103T, the fourth channel 104T, the fifth channel 105T and the eighth channel 108T all extend around the center arc of the first fluid control surface 1210T of the fixed valve plate 121T of the flat valve 10T, and the sixth channel 106T (the portion located in the extending area 12202T) and the seventh channel 107T all extend around the center arc of the second fluid control surface 1220T of the movable valve plate 122T. More preferably, the first channel 101T, the second channel 102T, the third channel 103T, the fourth channel 104T, the fifth channel 105T and the eighth channel 108T all extend in an arc around the central portion 12101T of the first fluid control surface 1210T of the fixed valve plate 121T of the flat valve 10T, the sixth channel 106T (which is located in the extended area 12202T) and the seventh channel 107T extend in an arc around the central area 12201T of the second fluid control surface 1220T of the movable valve plate 122T, the fourth channel 104T and the fifth channel 105T correspond to the same central angle, and the second channel 102T and the third channel 103T correspond to the same central angle, so as to easily realize the stepless control of the water flow rate by the flat valve 10T.

It can be understood that the distribution of the first passage 101T, the second passage 102T, the third passage 103T, the fourth passage 104T, the fifth passage 105T and the eighth passage 108T of the planar valve 10T of the water purifier 2 according to the first embodiment of the present invention at the first fluid control surface 1210T of the fixed valve plate 121T of the planar valve 10T, so that when the movable valve plate 122T of the flat valve 10T of the water purifier 2 rotates relative to the fixed valve plate 121T, so that when the flat valve 10T is switched from the standby operating position to the first purge operating position (or from the first purge operating position to the standby operating position), or is switched from the standby operating position to the second purge operating position (or from the second purge operating position to the standby operating position), even if the working position is not switched completely (or during switching), the movable valve plate 122T of the flat valve 10T can rotate relative to the fixed valve plate 121T to achieve stable conduction of the flow passage. The main reason is that when the flat valve 10T is switched from the standby operating position to the first purification operating position or from the first purification operating position to the standby operating position, during the switching process, the sixth channel 106T of the flat valve 10T is always in stable communication with only the raw water inlet channel 1012T and the first channel 101T, respectively, and the seventh channel 107T of the flat valve 10T is always in stable communication with only the fourth channel 104T and the fifth channel 105T, respectively; when the flat valve 10T is switched from the standby operating position to the second purification operating position or from the second purification operating position to the standby operating position, during the switching process, the sixth channel 106T of the flat valve 10 is always in stable communication with only the raw water inlet channel 1012T and the eighth channel 108T, and the seventh channel 107T of the flat valve 10T is always in stable communication with only the second channel 102T and the third channel 103T. The sixth channel 106T of the flat valve 10T is always in stable communication only with the raw water inlet channel 1012T and the first channel 101T, respectively, the seventh channel 107T of the flat valve 10T is always in stable communication only with the fourth channel 104T and the fifth channel 105T, respectively, and the sixth channel 106T of the flat valve 10 is always in stable communication only with the raw water inlet channel 1012T and the eighth channel 108T, respectively, the seventh channel 107T of the flat valve 10T is always in stable communication only with the second channel 102T and the third channel 103T, respectively, ensuring that no cross-flow occurs when the flat valve 10T is switched from the standby operating position to the first purification operating position or from the first purification operating position to the standby operating position, and from the standby operating position to the second purification operating position or from the second purification operating position to the standby operating position, thereby ensuring stepless control of the flow rate of the water flow through the control valve 10T during station switching.
As shown in fig. 26A to 27F of the drawings, it should be noted that when a user needs to switch the water purifier 2 according to the first embodiment of the present invention from the back-flushing operation state to the second purification operation state, the user only needs to rotate the movable valve plate 122T of the flat valve 10T counterclockwise by an equal angle, so that the first region 2001T of the second fluid control surface 1220T of the movable valve plate 122T faces the third portion 1203T of the first fluid control surface 1210T of the fixed valve plate 121T; when the user needs to switch the water purifier 2 from the second purification operating state to the standby operating state according to the first embodiment of the present invention, the user only needs to rotate the movable valve plate 122T of the planar valve 10T counterclockwise again by an equal angle, so that the first area 2001T of the second fluid control surface 1220T of the movable valve plate 122T faces the second portion 1202T of the first fluid control surface 1210T of the fixed valve plate 121T; when the user needs to switch the water purifier 2 from the standby operation state to the first purification operation state according to the first embodiment of the present invention, the movable valve plate 122T of the planar valve 10T only needs to be rotated counterclockwise again by an equal angle, so that the first area 2001T of the second fluid control surface 1220T of the movable valve plate 122T is opposite to the first portion 1201T of the first fluid control surface 1210T of the fixed valve plate 121T. In other words, the structure of the flat valve 10T of the water purifier 2 according to the present invention enables the four operation states of the back flush operation state, the second purification operation state, the standby operation state and the first purification operation state of the water purifier 2 to be continuously distributed, so that the switching between the adjacent operation states of the back flush operation state, the second purification operation state, the standby operation state and the first purification operation state of the water purifier 2 according to the present invention can be realized by only rotating the movable valve plate 122T of the flat valve 10T by an equal division angle. The switching manner among the four operating states of the water purifier 2 determined by the structure of the flat valve 10T of the water purifier 2 according to the present invention makes the switching among the four operating states of the water purifier 2 according to the present invention more suitable for the use habit of the user and makes it difficult for the user to switch between the operating states, which results in erroneous switching of the operating states due to different rotation angles. It can be understood that, since the extension portion 12102T and the edge portion 12103T of the first fluid control surface 1210T of the planar valve 10T of the water purifier 2 according to the first embodiment of the present invention are quartered, and the extension area 12202T and the edge area 12203T of the second fluid control surface 1220T of the movable valve plate 122T of the planar valve 10T are quartered, accordingly, the movable valve plate 122T of the planar valve 10T rotates 90 degrees for every operation state switching of the water purifier 2 according to the present invention. In other words, an angle of bisection between the movable valve plate 122T and the fixed valve plate 121T of the planar valve 10T is 90 degrees. Optionally, the extension portion 12102T and the edge portion 12103T of the first fluid control surface 1210T are equally divided into the first portion 1201T, the second portion 1202T, the third portion 1203T and the fourth portion 1204T counterclockwise, and the extension region 12202T and the edge region 12203T of the second fluid control surface 1220T of the movable valve plate 122T of the planar valve 10T are equally divided into the first region 2001T, the second region 2002T, the third region 2003T and the fourth region 2004T counterclockwise. At this time, the structure of the flat valve 10T of the water purifier 2 according to the present invention continuously distributes four operating states of the first purification operating state, the standby operating state, the second purification operating state, and the backwashing operating state of the water purifier 2, so that the switching between the adjacent operating states of the first purification operating state, the standby operating state, the second purification operating state, and the backwashing operating state of the water purifier 2 according to the present invention can be realized by rotating the movable valve plate 122T of the flat valve 10T by only one equal division angle. In addition, as described above, when the water purifier 2 according to the first embodiment of the present invention is switched from the standby operation state to the first purification operation state (or the second purification operation state), the stepless control of the flow rates of the inlet water and the outlet water of the water purifier 2 according to the present invention can be realized by adjusting the overlapping degree of the passages (the sixth passage 106T and the seventh passage 107T) of the movable valve plate 122T and the passages (the first passage 101T, the second passage 102T, the third passage 103T, the fourth passage 104T, the fifth passage 105T and the eighth passage 108T) of the fixed valve plate 121T. However, when the water purifier 2 of the present invention is switched from the standby operation state to the first purification operation state (or the second purification operation state), the sixth channel 106T (the portion in the extension area 12202T) of the movable valve plate 122T can be opposite to the first channel 101T (or the eighth channel 108T) of the fixed valve plate 121 by rotating the movable valve plate 122T by an equal division angle, and the seventh channel 107T is opposite to the fourth channel 104T and the fifth channel 105T (or the second channel 102T and the third channel 103T), so as to implement the state switching.

As known to those skilled in the art, a faucet water purifier directly installed in a faucet has a small volume due to the limitation of a use space where the faucet water purifier is located. When the tap water purifier utilizes the ultrafiltration filter element, particularly the ultrafiltration filter element which takes the ultrafiltration membrane wire as the main filter element, the ultrafiltration filter element is easy to stink and cannot be used continuously because of the accumulation of tap water impurities, such as microorganisms and other impurities, attached to the surface of the ultrafiltration membrane wire. The filtering device 20 of the water purifier 2 of the present invention allows the purified water generated from the primary filter element 22 to be supplied and also allows the surface of the ultrafiltration membrane wire 231 of the secondary filter element 23 to be cleaned by the purified water generated from the primary filter element 22, thereby preventing impurities such as microorganisms in the tap water from being accumulated in the secondary filter element 23 and preventing the impurities from being smelled and thus being unable to be used continuously.

More importantly, because the faucet water purifier has smaller volume, with the structure of the traditional faucet water purifier, when the ultrafiltration filter element is used for treating raw water such as tap water, blockage can occur in a short time. The water purifier 2 of the invention has the washing function to the ultrafiltration membrane wire 231 of the secondary filter element 23 when the water purifier utilizes the purified water generated by the primary filter element 22, thereby obviously improving the problem that the impurities are gathered and can not be discharged in time when the traditional tap water purifier uses the ultrafiltration filter element (or ultrafiltration membrane wire) to filter water, and leading the tap water purifier to use the ultrafiltration filter element to filter water to be possible. The greater significance of the water purifier 2 of the present invention is the potential for consumers to get rid of the bulky, expensive traditional desktop water purifiers.
