Detailed Implementation

[0045] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0046] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0047] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0049] Existing water purification equipment typically filters water by first passing it through a purification module for primary filtration, and then through an ultrafiltration module for secondary filtration, ensuring that the obtained water is ultrafiltered water that has undergone secondary filtration. However, the cost of ultrafiltration cartridges is relatively high, increasing the cost of replacing ultrafiltration cartridges and thus raising water costs in some scenarios where ultrafiltration is not required.

[0050] To solve the above problems, such as Figures 1-6 As shown, this embodiment provides a water purification device, which includes a purification component 1, an ultrafiltration component 2, and a pipeline assembly 3. The purification component 1 is provided with a purification inlet 121 and a purification outlet 122. The ultrafiltration component 2 is provided with an ultrafiltration inlet 221 and an ultrafiltration outlet 222. The pipeline assembly 3 includes a first pipeline 31, a second pipeline 32, and a third pipeline 33. The pipeline assembly 3 is provided with a purified water outlet 34 and an ultrafiltration water outlet 35. The purified water outlet 34 and the purification outlet 122... The ultrafiltration water outlet 35 is connected to the ultrafiltration water outlet 222. The second pipeline 32 includes a first branch pipeline 321 and a second branch pipeline 322 connected to each other. The second branch pipeline 322 is connected to the ultrafiltration water inlet 221. The third pipeline 33 is connected to the ultrafiltration water outlet 222. The purified water inlet 121 can be selectively connected to one of the first pipeline 31 and the first branch pipeline 321, and the purified water outlet 122 can be selectively connected to the other of the first pipeline 31 and the first branch pipeline 321. The water purification equipment provided in this embodiment refers to... Figure 3 and Figure 4As shown, when the purified water inlet 121 is connected to the first pipeline 31 and the purified water outlet 122 is connected to the first branch pipeline 321, the water flowing into the first pipeline 31 enters the purification component 1 through the purified water inlet 121. After being filtered by the purification component 1, it flows into the first branch pipeline 321 through the purified water outlet 122. A portion of the water in the first branch pipeline 321 is directly discharged through the first branch pipeline 321 and the purified water outlet 34, while the other portion of the water in the first branch pipeline 321 flows through... The water flows through the first branch pipe 321 into the second branch pipe 322, then through the ultrafiltration inlet 221 into the ultrafiltration module 2. After secondary filtration by the ultrafiltration module 2, it flows through the ultrafiltration outlet 222 into the third branch pipe 33, and finally out through the third branch pipe 33 and the ultrafiltration water outlet 35. Thus, the primary purified water filtered by the purification module 1 is obtained through the first branch pipe 321, and the ultrafiltration water that has passed through the purification module 1 and the ultrafiltration module 2 is obtained through the third branch pipe 33. (Refer to...) Figure 5 and Figure 6 As shown, when the purification inlet 121 is connected to the first branch pipe 321 and the purification outlet 122 is connected to the first pipe 31, a portion of the water flowing into the first branch pipe 321 enters the purification component 1 through the purification inlet 121. After being filtered by the purification component 1, it flows into the first pipe 31 through the purification outlet 122 and is directly discharged through the first pipe 31 and the purified water outlet 34. Another portion of the water flowing into the first branch pipe 321 enters the second branch pipe 322 through the first branch pipe 321, then enters the ultrafiltration component 2 through the ultrafiltration inlet 221. After being filtered by the ultrafiltration component 2, it flows into the third pipe 33 through the ultrafiltration outlet 222 and is finally discharged through the third pipe 33 and the ultrafiltration water outlet 35. Thus, the primary purified water filtered by the purification component 1 is obtained through the first pipe 31, and the ultrafiltration water directly filtered by the ultrafiltration component 2 is obtained through the third pipe 33. The above configuration enables the water purification device to supply water of different qualities according to the water demand in different scenarios, meeting users' requirements for different filtered water qualities. This eliminates the need for all water to be filtered through the ultrafiltration component 2, extending its lifespan and reducing water costs. Furthermore, the device achieves differentiated water supply by designing the piping component 3 as multiple pipes, resulting in a simple structure.

[0051] It should be noted that pipeline assembly 3 is also equipped with a raw water inlet 37, as shown in the reference section. Figure 3 and Figure 4 As shown, when the purified water inlet 121 is connected to the first pipeline 31 and the purified water outlet 122 is connected to the first branch pipeline 321, the open end of the first pipeline 31 is the raw water inlet 37, the open end of the first branch pipeline 321 is the purified water outlet 34, and the open end of the third pipeline 33 is the ultrafiltration water outlet 35; (Refer to...) Figure 5 and Figure 6 As shown, when the purified water inlet 121 is connected to the first branch pipe 321 and the purified water outlet 122 is connected to the first pipe 31, the opening end of the first branch pipe 321 is the raw water inlet 37, the opening end of the first pipe 31 is the purified water outlet 34, and the opening end of the third pipe 33 is the ultrafiltration water outlet 35.

[0052] Optionally, in this embodiment, as Figure 1 As shown, the purification component 1 and the ultrafiltration component 2 are arranged sequentially along the first direction, and the pipeline component 3 extends along the first direction. This arrangement ensures that the purification component 1 and the ultrafiltration component 2 occupy the extension space along the first direction, and the pipeline component 3 also occupies the extension space along the first direction, avoiding additional space occupation in other directions by structural components. This results in a more compact and rational structure, allowing the purification component 1, the ultrafiltration component 2, and the pipeline component 3 to make efficient use of the internal space of the water purification equipment along the first direction. Optionally, the first direction can be the width direction of the water purification equipment or the length direction of the width direction of the water purification equipment.

[0053] Optionally, in this embodiment, as Figure 1 and Figure 4 As shown, the first branch pipe 321 and the second branch pipe 322 are connected in a bent shape. This arrangement effectively slows down the flow rate of water between the first branch pipe 321 and the second branch pipe 322, preventing excessive water flow and ensuring the filtration effect of the purification component 1 and the ultrafiltration component 2. Optionally, in this embodiment, the third pipe 33 is bent, effectively slowing down the flow rate of water in the third pipe 33 and ensuring the stability of the discharge from the third pipe 33.

[0054] In this embodiment, as Figure 2 As shown, the ultrafiltration assembly 2 includes an ultrafiltration outer cylinder 21, an ultrafiltration upper end cover 22, an ultrafiltration lower end cover 23, and an ultrafiltration filter element 24. The ultrafiltration outer cylinder 21 has a first opening 211 and a second opening 212. The ultrafiltration upper end cover 22 is sealed in the first opening 211. The ultrafiltration upper end cover 22 is provided with an ultrafiltration inlet 221 and an ultrafiltration outlet 222 at intervals. The ultrafiltration lower end cover 23 is sealed in the second opening 212. The ultrafiltration filter element 24 is housed in the ultrafiltration outer cylinder 21. The ultrafiltration filter element 24 is used to filter the water entering the ultrafiltration outer cylinder 21, and the outlet of the ultrafiltration filter element 24 is connected to the ultrafiltration outlet 222. The structure of the ultrafiltration component 2 is designed such that water in the second branch pipe 322 enters the ultrafiltration outer cylinder 21 through the ultrafiltration inlet 221 on the ultrafiltration upper end cover 22. After being filtered by the ultrafiltration filter element 24 in the ultrafiltration outer cylinder 21, the water passes through the outlet of the ultrafiltration filter element 24 and the ultrafiltration outlet 222 in sequence and enters the third pipe 33. Finally, it is discharged through the third pipe 33, thereby obtaining ultrafiltration water filtered by the ultrafiltration component 2.

[0055] Optionally, in this embodiment, as Figure 2 As shown, the ultrafiltration filter element 24 includes a support tube 241 and multiple ultrafiltration membranes 242. The support tube 241 extends along the axial direction of the ultrafiltration outer cylinder 21 and is fixedly connected to the ultrafiltration lower end cap 23. The multiple ultrafiltration membranes 242 are arranged at intervals along the circumference of the support tube 241, surrounding the outer periphery of the support tube 241, and the outlet of the ultrafiltration membrane 242 is connected to the ultrafiltration outlet 222. The above-mentioned structural design of the ultrafiltration filter element 24 allows water entering the ultrafiltration outer cylinder 21 to permeate into each ultrafiltration membrane 242, achieving water filtration. The ultrafiltration water entering the ultrafiltration membrane 242 flows upward along the ultrafiltration membrane 242 under the action of water pressure, passing through the outlet of the ultrafiltration membrane 242 and the ultrafiltration outlet 222 in sequence before entering the third pipeline 33. In addition, by setting up the support tube 241 and arranging multiple ultrafiltration membranes 242 at intervals along the circumference of the support tube 241, the support and fixation effect of each ultrafiltration membrane 242 is achieved, and the uniformity of the arrangement of ultrafiltration membranes 242 in the ultrafiltration outer cylinder 21 is also ensured, thus guaranteeing the filtration effect on water.

[0056] Optionally, in this embodiment, as Figure 2 As shown, each ultrafiltration membrane 242 is U-shaped, and both ends of the ultrafiltration membrane 242 are water outlets. The above-mentioned structural design of the ultrafiltration membrane 242 further ensures the contact area between the ultrafiltration membrane 242 and the water inside the ultrafiltration outer cylinder 21, thus ensuring the filtration effect of the ultrafiltration membrane 242 on the water.

[0057] Optionally, a plurality of water inlet holes 2411 are spaced apart on the outer peripheral wall of the support tube 241. The end of the support tube 241 away from the lower end cover 23 of the ultrafiltration system is sealed. The lower end cover 23 of the ultrafiltration system has a flushing hole communicating with the end of the support tube 241, and a flushing valve is installed in the flushing hole. The above arrangement ensures that when the ultrafiltration filter element 24 needs to be flushed, the ultrafiltration outlet 222 is sealed, and cleaning water is introduced into the ultrafiltration outer cylinder 21 through the ultrafiltration inlet 221. The cleaning water can carry impurities through the water inlet holes 2411 into the support tube 241, and then be discharged from the ultrafiltration assembly 2 through the support tube 241 and the flushing valve in the flushing hole, thereby realizing the flushing operation of the ultrafiltration filter element 24.

[0058] Optionally, in this embodiment, as Figure 3 and Figure 5As shown, the purification assembly 1 includes a purification outer cylinder 11, a purification upper cover 12, a purification lower cover 13, and a purification filter element 14. The purification outer cylinder 11 has a first opening 111 and a second opening 112. The purification upper cover 12 is sealed within the first opening 111 and has a purification inlet 121 and a purification outlet 122 spaced apart. The purification lower cover 13 is sealed within the second opening 112. The purification filter element 14 is housed within the purification outer cylinder 11 and is used to filter the water entering the purification outer cylinder 11. The outlet of the purification filter element 14 is connected to the purification outlet 122. This structural design of the purification assembly 1 ensures that water entering the purification outer cylinder 11 through the purification inlet 121 is filtered by the purification filter element 14 and then discharged sequentially through the outlet of the purification filter element 14 and the purification outlet 122, thus obtaining water filtered by the purification assembly 1.

[0059] Optionally, in this embodiment, as Figure 3 and Figure 5 As shown, the purification filter element 14 includes a central tube 141 and a purification membrane 142. The central tube 141 extends along the axial direction of the purification outer cylinder 11 and is connected between the purification lower end cover 13 and the purification upper end cover 12. Multiple inlet holes 1411 are spaced apart on the wall of the central tube 141. The purification membrane 142 surrounds the outer periphery of the central tube 141, and the outlet of the central tube 141 is connected to the purification outlet 122. This structural design of the purification filter element 14 ensures that water entering the purification outer cylinder 11 is filtered by the purification membrane 142 before entering the central tube 141, and then discharged sequentially through the outlet of the central tube 141 and the purification outlet 122.

[0060] In this embodiment, as Figure 7 and Figure 8 As shown, the first branch pipe 321 and the second branch pipe 322 are pluggably connected. This arrangement makes it easier to install and disassemble the first branch pipe 321 and the second branch pipe 322, and also makes it easier to separate the purification component 1 and the ultrafiltration component 2 along with their corresponding pipes, making disassembly and assembly more flexible.

[0061] In other embodiments, the first branch pipe 321 and the second branch pipe 322 are integrally formed, so that the second pipe 32 is a single pipe, which ensures the sealing effect of the second pipe 32 and also ensures the structural strength of the second pipe 32.

[0062] Optionally, such as Figure 7 and Figure 8As shown, the outer peripheral wall of the first branch pipe 321 is provided with a first annular groove 3211, and the outer peripheral wall of the second branch pipe 322 is provided with a second annular groove 3221. One of the bottom walls of the first annular groove 3211 and the second annular groove 3221 is provided with a insertion hole 3222. The pipe assembly 3 also includes a locking clamp 36, which engages with one of the first annular groove 3211 and the second annular groove 3221. The inner wall of the locking clamp 36 is provided with an insertion protrusion 361, which passes through the insertion hole 3222 and abuts against the other of the bottom walls of the first annular groove 3211 and the second annular groove 3221. This configuration effectively ensures the stability of the insertion and fixing of the first branch pipe 321 and the second branch pipe 322, and is simple in structure and easy to operate. In this embodiment, the first branch pipe 321 is inserted into the second branch pipe 322. The bottom wall of the second annular groove 3221 is provided with a insertion hole 3222. The locking clamp 36 is engaged in the second annular groove 3221, and the insertion protrusion 361 passes through the insertion hole 3222 and abuts against the bottom wall of the first annular groove 3211. Optionally, in this embodiment, the outer peripheral wall of the first branch pipe 321 is provided with a plurality of first annular grooves 3211 at intervals. The plurality of first annular grooves 3211 are distributed at intervals along the insertion direction. The insertion protrusion 361 can be selectively engaged with the bottom wall of one of the first annular grooves 3211, thereby adjusting the insertion depth of the first branch pipe 321 and the second branch pipe 322 by selecting to engage with different first annular grooves 3211. In other embodiments, the second branch pipe 322 is inserted into the first branch pipe 321. The bottom wall of the first annular groove 3211 is provided with a insertion hole 3222. The locking clamp 36 is engaged in the first annular groove 3211, and the insertion protrusion 361 passes through the insertion hole 3222 and abuts against the bottom wall of the second annular groove 3221. Optionally, in other embodiments, when the second branch pipe 322 is inserted into the first branch pipe 321, the outer peripheral wall of the second branch pipe 322 is provided with a plurality of second annular grooves 3221 at intervals. The plurality of second annular grooves 3221 are distributed at intervals along the insertion direction. The insertion protrusion 361 can selectively engage with the bottom wall of one of the second annular grooves 3221, thereby adjusting the insertion depth of the first branch pipe 321 and the second branch pipe 322 by selecting to engage with different second annular grooves 3221. Optionally, in this embodiment, the inner wall of the locking clamp 36 is provided with a plurality of insertion protrusions 361 spaced apart along its circumference, and a plurality of insertion holes 3222 are also provided at intervals, with the plurality of insertion protrusions 361 and the plurality of insertion holes 3222 corresponding one-to-one.

[0063] Optionally, in this embodiment, the second branch pipe 322 is pluggably connected to the ultrafiltration inlet 221, and the third pipe 33 is pluggably connected to the ultrafiltration outlet 222. This arrangement facilitates the installation and disassembly of the ultrafiltration assembly 2 and the pipe assembly 3, making operation more convenient. Since the specific structure of the pluggable connection is basically the same as the specific structure of the pluggable connection between the first branch pipe 321 and the second branch pipe 322, it will not be described again here.

[0064] Optionally, in this embodiment, the purified water inlet 121 can be selectively and pluggably connected to one of the first pipe 31 and the first branch pipe 321, and the purified water outlet 122 can be selectively and pluggably connected to the other of the first pipe 31 and the first branch pipe 321. This arrangement not only facilitates the installation and disassembly of the purification component 1 and the pipe assembly 3, making operation more convenient, but also facilitates connecting the purified water outlet 122 and the purified water inlet 121 to the required pipes as needed, making operation convenient. Since the specific structure of the pluggable connection is basically the same as the specific structure of the pluggable connection between the first branch pipe 321 and the second branch pipe 322, it will not be described again here.

[0065] Optionally, in this embodiment, as Figure 7 and Figure 8 As shown, the third pipeline 33 includes a first pipe section 331 and a second pipe section 332. The first pipe section 331 is connected to the ultrafiltration outlet 222. The first pipe section 331 and the second pipe section 332 are pluggably connected, and the outer wall of the first branch pipeline 321 is fixedly connected to the outer wall of the second pipe section 332. This configuration allows the first pipe section 331 and the second pipe section 332 to be separated, and the first branch pipeline 321 and the second branch pipeline 322 to be separated. A bend connects the first branch pipeline 321 and the second pipe section 332, allowing the primary purified water filtered by the purification component 1 to be obtained simultaneously through the second pipe section 332 and the first pipeline 31. Since the pluggable connection of the first pipe section 331 and the second pipe section 332 is essentially the same as the pluggable connection of the first branch pipeline 321 and the second pipe section 322, it will not be described again here.
