Description

Technical Field

[0001] This utility model relates to a water purifier, and more particularly to an ultrafiltration water purifier. This utility model further provides a control valve for the ultrafiltration water purifier. Background Technology

[0002] As people's living standards improve and their awareness of health increases, their demands for the quality of drinking water are also rising. However, in many countries, most tap water sources are surface water, which is supplied to users after purification and disinfection at water treatment plants. Water treatment at these plants is relatively rudimentary and insufficient to remove all impurities, such as particulate contaminants (flocculated gels, silt, and even bacteria). Furthermore, aging water supply networks can introduce new pollutants into the tap water. To further purify tap water and obtain cleaner water, people use water purification equipment. For example, ultrafiltration water purifiers are used to treat tap water to obtain cleaner purified water.

[0003] Ultrafiltration water purifiers typically purify raw water through their ultrafiltration membrane fibers. For example, if the ultrafiltration water purifier uses internal pressure ultrafiltration membrane fibers, raw water flows into the inner pores of the membrane fibers and is purified under water pressure to obtain purified water. After a period of use, dirt easily accumulates inside the ultrafiltration membrane fibers, causing them to become clogged. To prevent the inner pores of the ultrafiltration membrane fibers from being clogged, they need to be flushed periodically. Most existing ultrafiltration filter cartridges discharge wastewater through a drain port at the bottom of the cartridge. However, in actual use, the water flow rate of a single ultrafiltration filter cartridge may be relatively small, requiring multiple cartridges to be used in combination. In this case, the bottom-mounted drain port creates installation difficulties when using multiple cartridges together. Furthermore, the bottom-mounted drain port also makes cartridge replacement inconvenient. Utility Model Content

[0049] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the elements can be multiple, and the term "a" should not be understood as a limitation on the number.

[0050] Refer to the attached diagram in the instruction manual. Figures 1 to 13BAn ultrafiltration water purifier according to an embodiment of the present invention is described, wherein the ultrafiltration water purifier includes a control valve 10, an ultrafiltration device 20, and a connecting assembly 30, wherein the connecting assembly 30 includes a first connecting pipe 31, a second connecting pipe 32, and a third connecting pipe 33, wherein the control valve 10 has a first opening 1101, a second opening 1102, a third opening 1103, a fourth opening 1104, a fifth opening 1105, and a sixth opening 1106, wherein the ultrafiltration device 20 has a raw water channel 201, a purified water channel 202, and a sewage discharge channel 203, wherein the first connecting pipe 31 forms a first water chamber 310, the second connecting pipe 32 forms a second water chamber 320, and the third connecting pipe 33 forms a third water chamber 330, wherein the control valve The first opening 1101 of the control valve 10 is connected to the first water chamber 310, the fourth opening 1104 is connected to the raw water channel 201, the second opening 1102 is connected to the second water chamber 320, the fifth opening 1105 is connected to the purified water channel 202, the third opening 1103 is connected to the third water chamber 330, and the sixth opening 1106 is connected to the sewage discharge channel 203. When the control valve 10 is in the conducting working position, it can form a raw water conducting channel 601 connected to the first opening 1101 and the fourth opening 1104, a purified water conducting channel 602 connected to the second opening 1102 and the fifth opening 1105, and a flushing channel 603 connected to the third opening 1103 and the sixth opening 1106.Accordingly, when the control valve 10 is in the open position, raw water can flow from the first water chamber 310 of the first connecting pipe 31, the first opening 1101 of the control valve 10, the raw water conduction channel 601, and the fourth opening 1104 to the raw water channel 201. When ultrafiltration is required to obtain purified water, the water in the second water chamber 320 can flow freely. At this time, the purified water produced after ultrafiltration flows through the purified water channel 202 to the fifth opening 1105, and further flows from the purified water conduction channel 602 and the second opening 1102 to the second water chamber 320 of the second connecting pipe 32 to be supplied. When the ultrafiltration membrane fibers need to be flushed, the free flow of water in the second water chamber 320 can be prevented, while the free flow of water in the third water chamber 330 can be allowed. At this time, raw water can flow from the first water chamber 310 of the first connecting pipe 31, the first opening 1101 of the control valve 10, the raw water conduction channel 601, and the fourth opening 1104 to the raw water channel 201, thereby allowing the raw water to flush the ultrafiltration membrane fibers 21 of the ultrafiltration device 20. The resulting wastewater flows through the sewage discharge channel 203 to the sixth opening 1106, and then through the flushing channel 603 and the third opening 1103 to the third water chamber 330 of the third connecting pipe 33 for discharge. It can be understood that when flushing the ultrafiltration membrane fibers, the third water chamber 330 is in a conductive state, allowing the water inside to flow freely; when flushing the ultrafiltration membrane fibers is no longer needed, the third water chamber 330 can be blocked, putting it in a disconnected state and preventing the flow of water inside.

[0051] As shown in the attached image. Figures 1 to 13B As shown, the third connecting pipe 33 of the connecting assembly 30 of the ultrafiltration water purifier according to an embodiment of the present invention has three connecting openings 3301. One connecting opening 3301A is connected to the third opening 1103, one connecting opening 3301B is adapted to communicate with the third connecting pipe of the connecting assembly of the upstream ultrafiltration water purifier, and one connecting opening 3301C is adapted to communicate with the third connecting pipe of the connecting assembly of the downstream ultrafiltration water purifier. Accordingly, the third connecting pipe 33 forms a three-way structure, and when the control valve 10 is in the open position, it enables the sewage discharge channels 203 of multiple ultrafiltration devices of the present invention to be connected in parallel. (See attached figures) Figure 1 As shown in the attached figures, the number of ultrafiltration water purifiers according to this embodiment of the invention connected in parallel via the third connecting pipe 33 is at least two. Figures 1 to 11As shown, in the embodiment of the present invention, the first connecting pipe 31 of the connecting assembly 30 of the ultrafiltration water purifier has three first connecting openings 3101, and the second connecting pipe 32 has three second connecting openings 3201. One first connecting opening 3101A of the three first connecting openings 3101 is connected to the first opening 1101; one first connecting opening 3101B is adapted to be connected to the first connecting pipe (or second connecting pipe, raw water source) of the connecting assembly of the upstream ultrafiltration water purifier; and one first connecting opening 3101C is adapted to be connected to the first connecting pipe (or second connecting pipe) of the connecting assembly of the downstream ultrafiltration water purifier. One second connecting opening 3201A of the three second connecting openings 3201 is connected to the second opening 1102; one second connecting opening 3201B is adapted to be connected to the second connecting pipe of the connecting assembly of the upstream ultrafiltration water purifier; and one second connecting opening 3201C is adapted to be connected to the first connecting pipe (or second connecting pipe, end water outlet) of the connecting assembly of the downstream ultrafiltration water purifier. Accordingly, the first connecting pipe 31 and the second connecting pipe 32 respectively form a three-way structure, wherein when the second communication opening 3201C of the connecting component 30 of the upper stage ultrafiltration water purifier of the present invention is connected to the first communication opening 3101B of the connecting component 30 of the lower stage ultrafiltration water purifier, and the control valve 10 of the ultrafiltration water purifier is in the conducting working position, the ultrafiltration devices of the two ultrafiltration water purifiers of the present invention will be connected in series and can perform multi-stage purification of raw water; when the two (or more) ultrafiltration water purifiers of the present invention are connected in series, the control valve 10 of the ultrafiltration water purifier is in the conducting working position, the ultrafiltration devices of the two ultrafiltration water purifiers of the present invention will be connected in series and can perform multi-stage purification of raw water; when the control valve 10 of the two ultrafiltration water purifiers is in the conducting working position, the control valve 30 of the two ultrafiltration water purifiers of the present invention is connected in series, and the control valve 30 of ... When the first communication opening 3101C of the connecting component 30 of the previous stage ultrafiltration water purifier is connected to the first communication opening 3101B of the next stage connecting component 30, and the second communication opening 3201C of the previous stage connecting component 30 is connected to the second communication opening 3201B of the next stage connecting component 30, and the control valve 10 of the ultrafiltration water purifier is in the conducting position, the ultrafiltration devices of the two ultrafiltration water purifiers of this invention will be connected in parallel and can simultaneously purify the raw water. Therefore, the ultrafiltration water purifiers of this invention can be connected in series or in parallel by changing the interconnection method of the connecting components 30.

[0052] As shown in the attached image. Figures 4A to 13BAs shown, the control valve 10 of the ultrafiltration water purifier according to this embodiment is a planar valve, wherein the planar valve 10 includes a valve body 11 and a valve core 12, wherein the valve body 11 forms a valve cavity 110, a first opening 1101, a second opening 1102, a third opening 1103, a fourth opening 1104, a fifth opening 1105 and a sixth opening 1106, wherein the valve core 12 is disposed within the valve cavity 110 of the valve body 11, and the first connecting pipe 31, the second connecting pipe 32 and the third connecting pipe 33 are respectively connected to the control valve 10. Accordingly, since the third connecting pipe 33 is connected to the control valve 10, the raw water inlet, the purified water outlet and the wastewater outlet of the ultrafiltration device 20 are all formed at the high end of the ultrafiltration device 20, and it no longer has the problem of inconvenient replacement of the ultrafiltration filter element caused by the wastewater outlet of the existing ultrafiltration device being at the bottom.

[0053] As shown in the attached image. Figures 4A to 13B As shown, the valve core 12 of the control valve 10 of the ultrafiltration water purifier according to an embodiment of the present invention includes a fixed valve plate 121 and a movable valve plate 122. The fixed valve plate 121 has a first fluid control surface 1210, and the movable valve plate 122 has a second fluid control surface 1220. The planar valve 10 has a first through hole 101, a second through hole 102, a third through hole 103, a fourth through hole 104, a fifth through hole 105, and a sixth through hole 106. The first through hole 101, the second through hole 102, and the third through hole 103 are respectively disposed on the fixed valve plate 121 and extend 1210 from the first fluid control surface of the fixed valve plate 121. The fourth through hole 104, the fifth through hole 105, and the sixth through hole 106 are respectively disposed on the movable valve plate 122 and extend 1210 from the first fluid control surface of the fixed valve plate 121. The second fluid control surface 1220 extends, wherein one end of the first through hole 101 is connected to the first opening 1101, one end of the second through hole 102 is connected to the second opening 1102, one end of the third through hole 103 is connected to the third opening 1103, one end of the fourth through hole 104 is connected to the fourth opening 1104, one end of the fifth through hole 105 is connected to the fifth opening 1105, and one end of the sixth through hole 106 is connected to the sixth opening 1106. The second fluid control surface 1220 of the movable valve plate 122 is disposed on the first fluid control surface 1210 of the fixed valve plate 121, and the movable valve plate 122 is configured to rotate relative to the fixed valve plate 121. The first opening 1101 of the valve body 11 is adapted to be connected to the water source to be treated (e.g., raw water source, tap water pipe).

[0054] As shown in the attached image. Figure 5A , Figure 5B and Figures 12A to 13BAs shown, in the embodiment of the present invention, the movable valve plate 122 of the planar valve 10 of the ultrafiltration water purifier is configured to rotate relative to the fixed valve plate 121. When the movable valve plate 122 rotates relative to the fixed valve plate 121, and the planar valve 10 is in a conducting working position, the first through hole 101 of the planar valve 10 is connected to the fourth through hole 104, thereby forming a raw water conducting channel 601 that is connected to the first opening 1101 and the fourth opening 1104 respectively; the second through hole 102 of the planar valve 10 is connected to the fifth through hole 105, thereby forming a purified water conducting channel 602 that is connected to the second opening 1102 and the fifth opening 1105 respectively; the third through hole 103 of the planar valve 10 is connected to the sixth through hole 106, thereby forming a flushing channel 603 that is connected to the third opening 1103 and the sixth opening 1106 respectively. In other words, when the planar valve 10 of the ultrafiltration water purifier of this utility model is in the open working position and the water flows freely in the second water chamber 320, the water can flow through the first opening 1101, the first through hole 101, the fourth through hole 104, and the fourth opening 1104 of the planar valve 10 in sequence under the action of water pressure into the raw water channel 201. After the raw water is treated by the ultrafiltration device 20, the purified water is collected in the purified water channel 202, and under the action of water pressure, it further flows through the fifth opening 1105, the fifth through hole 105, the second through hole 102, and the second opening 1102 to the second water chamber 320 of the second connecting pipe 32 and the lifted water. When the planar valve 10 of the ultrafiltration water purifier of this utility model is in the open working position and the water flows freely in the third water chamber 330, the raw water flows under the action of water pressure through the first opening 1101, the first through hole 101, the fourth through hole 104, and the fourth opening 1104 of the planar valve 10 into the raw water channel 201. After the raw water rinses the ultrafiltration device 20, the resulting sewage gathers in the sewage discharge channel 203 and, under the action of water pressure, further flows through the sixth opening 1106, the sixth through hole 106, the third through hole 103, and the third opening 1103 to the third water chamber 330 of the third connecting pipe 33 and is discharged.In other words, when the planar valve 10 of the ultrafiltration water purifier of this utility model is in the conducting working position and the ultrafiltration membrane fiber needs to be flushed, the third water chamber 330 of the third connecting pipe 33 is in the conducting state, and the water flow can flow freely in the third water chamber 330. Thus, the raw water flow, under the action of water pressure, flows sequentially through the first opening 1101, the first through hole 101, the fourth through hole 104, and the fourth opening 1104 of the planar valve 10 into the raw water channel 201. After the raw water flushes the ultrafiltration device 20, the resulting sewage gathers in the sewage discharge channel 203, and under the action of water pressure, further flows through the sixth opening 1106, the sixth through hole 106, the third through hole 103, and the third opening 1103 to the third water chamber 330 of the third connecting pipe 33 and is discharged. Preferably, the ultrafiltration membrane fiber of the ultrafiltration water purifier of this invention is an internal pressure ultrafiltration membrane fiber. When the planar valve 10 of the ultrafiltration water purifier of this invention is in the open working position, raw water flows through and washes the inner pores of the ultrafiltration membrane fiber. Optionally, the ultrafiltration membrane fiber of the ultrafiltration water purifier of this invention is an external pressure ultrafiltration membrane fiber. When the planar valve 10 of the ultrafiltration water purifier of this invention is in the open working position, raw water flows through and washes the outer surface of the ultrafiltration membrane fiber.

[0055] As shown in the attached image. Figure 6A , Figure 6B and Figures 12A to 13B As shown, further, when the movable valve plate 122 of the planar valve 10 of the ultrafiltration water purifier of this utility model rotates relative to the fixed valve plate 121, so that the planar valve 10 is in a water-cut-off working position, the first through hole 101, the second through hole 102, and the third through hole 103 of the planar valve 10 are closed by the movable valve plate 122, and the fourth through hole 104, the fifth through hole 105, and the sixth through hole 106 are closed by the fixed valve plate 121. Correspondingly, since the fourth through hole 104, the fifth through hole 105, and the sixth through hole 106 are closed by the fixed valve plate 121, the flow of raw water to the ultrafiltration device 20 is prevented, the backflow of purified water flowing out of the ultrafiltration device 20 is prevented, and the backflow of wastewater after rinsing the ultrafiltration device 20 is also prevented. At this time, when the user disassembles and replaces the ultrafiltration device 20, water leakage will not occur. It is understood that when the plane valve 10 of the ultrafiltration water purifier of this utility model is in the water-off working position, the ultrafiltration water purifier of this utility model is in the water-off working state.

[0056] As shown in the attached image. Figures 4A to 10EAs shown, the ultrafiltration water purifier according to the embodiment of the present invention further includes a drive assembly 80, the drive assembly 80 including at least one first drive element 81 and at least one second drive element 82, wherein the first drive element 81 is fixedly disposed on the ultrafiltration device 20, and the second drive element 82 is fixedly disposed on the moving valve plate 122, wherein the first drive element 81 and the second drive element 82 are configured to be able to mesh with each other respectively.

[0057] As shown in the attached image. Figures 4A to 10E As shown in the figure, in the ultrafiltration water purifier according to an embodiment of the present invention, the first driving element 81 of the driving assembly 80 is a first engaging protrusion 811 fixed to the ultrafiltration device 20. The second driving element 82 includes a cylindrical body 822 disposed on the movable valve plate 122 and at least one second engaging protrusion 821 extending inward from the inner wall 8220 of the cylindrical body 822.
