Description
Technical Field
[0001] This utility model relates to the field of water purifier technology, specifically to a dual-inlet, dual-outlet water purifier. Background Technology
[0002] As an important device for deep purification of household drinking water, water purifiers have seen their popularity increase year by year. Common water purifiers on the market usually adopt a split structure, that is, the water purification unit (containing the filter) is placed in the cabinet under the sink and connected to the faucet installed on the countertop through a long pipe. This traditional structure has problems such as complicated piping, large space occupation, and inconvenient installation. To solve the above problems, the industry has gradually developed a structure that integrates the filter and faucet on the same base, making the space layout more compact, reducing the space occupied inside the cabinet, and simplifying the installation process.
[0003] However, existing water purifier faucets using this type of water collector typically use a single-inlet, single-outlet water circuit structure. This means that only one inlet pipe is directly connected to the inlet end of the filter cartridge to deliver raw water to the filter cartridge for filtration. Then, another independent outlet pipe connects the filtered water to the faucet. This results in the connection between the filter cartridge and the inlet pipe being under pressure for a long time, which may lead to slow seepage or leakage. In severe cases, it may damage the cabinet and cause property damage. Utility Model Content
[0004] To address the technical problems existing in the background art, this utility model proposes a dual-inlet, dual-outlet water purifier.
[0005] The technical solution adopted by this utility model to solve its technical problem is as follows:
[0006] A dual-inlet, dual-outlet water purifier includes a base, on which a filter assembly and a water faucet are provided. The water faucet includes an inlet section and an outlet section, with a drain hole on the outlet section. An outlet valve is provided on the inlet section, and a first conveying channel and a second conveying channel are provided inside the outlet valve. The outlet valve can be rotated to connect or disconnect the first and second conveying channels.
[0007] The base is provided with a first water inlet pipe, a second water inlet pipe, and a return pipe. The first water inlet pipe is connected to the water inlet end of the first conveying channel, the output end of the first conveying channel is connected to the return pipe, the outlet end of the return pipe is connected to the water inlet end of the filter element assembly, the outlet end of the filter element assembly is connected to the water inlet end of the second water inlet pipe, the outlet end of the second water inlet pipe is connected to the water inlet end of the second conveying channel, the outlet end of the second conveying channel is connected to the water outlet section, and the water outlet section is provided with a first water outlet channel and a second water outlet channel that connect to the drain hole.
[0008] Preferably, the water outlet valve includes an inlet body and an outlet knob mounted on the inlet body. The bottom of the inlet body is provided with a first inlet hole, a second inlet hole, and a first outlet hole. A second outlet hole is formed on the side wall of the inlet body. The outlet knob is provided with a first connecting groove for connecting the first inlet hole and the first outlet hole, and a second connecting groove for connecting the second inlet hole and the second outlet hole. The first connecting groove connects the first inlet hole and the first outlet hole to form a first conveying channel, and the second connecting groove connects the second inlet hole and the second outlet hole to form a second conveying channel. With the above improvements, rotating the outlet knob can simultaneously control the opening and closing of the two water paths. The first connecting groove and the second connecting groove are independently set inside the knob, corresponding to the raw water and purified water channels respectively, realizing the physical isolation of the two water flows, preventing cross-contamination. In addition, the three-dimensional perforation on the bottom and side wall of the inlet body effectively shortens the water flow path, making the entire water circuit structure more compact, reducing the number of pipe joints, effectively reducing the risk of leakage, and improving the reliability and service life of the product.
[0009] Preferably, the outlet valve has an open state and a closed state; when in the open state, the two ends of the first connecting groove are respectively connected to the first inlet hole and the first outlet hole, and the two ends of the second connecting groove are respectively connected to the second inlet hole and the second outlet hole; when in the closed state, the two ends of the first connecting groove are respectively misaligned and sealed with the first inlet hole and the first outlet hole, and the two ends of the second connecting groove are respectively misaligned and sealed with the second inlet hole and the second outlet hole. Through the above improvements, when open, the first connecting groove and the second connecting groove are precisely connected to the corresponding water holes to ensure smooth dual-path water supply; when closed, the connecting groove and the water hole are completely misaligned to form a seal, preventing water leakage and simplifying the overall water circuit structure.
[0010] Preferably, the water outlet includes a first water outlet arm horizontally mounted on the water outlet and a second water outlet arm horizontally mounted on the first water outlet arm. The drain hole is located on the second water outlet arm and is positioned away from the first water outlet arm. The inlet end of the second water outlet arm is provided with a second inlet seat, and the outlet end of the second water outlet arm is provided with an outlet seat. Second delivery pipes are connected to both sides of the second inlet seat, and the second delivery pipes are connected to the outlet seat. The two second delivery pipes respectively form a first water outlet channel and a second water outlet channel. Through the above improvements, the first water outlet arm can rotate horizontally around the water outlet, and the second water outlet arm can rotate horizontally independently relative to the first water outlet arm. The combination of the two forms a multi-angle folding and extension mechanism, which allows the water outlet to cover a larger area, thereby improving the user experience. Furthermore, two second delivery pipes are set on both sides of the second inlet seat and connected in parallel to the outlet seat to form a dual-channel synchronous water delivery structure, which greatly increases the water flow rate and meets the needs of large water volume scenarios such as quick water intake in the kitchen and washing large items.
[0011] Preferably, the inlet end of the first water outlet arm is provided with a first water inlet seat that connects to the outlet end of the second conveying channel, the outlet end of the first water outlet arm is provided with an outlet connector, and a first conveying pipe connecting the first water inlet seat and the outlet connector is provided inside the first water outlet arm. The second water inlet seat is connected to the outlet connector. Through the above improvements, the first water inlet seat, the outlet connector, the second water inlet seat, and the outlet seat work together to ensure reliable water flow at the rotating connection of the double rotating arms, and smooth and unobstructed water flow at the moving joint, thereby improving the user's water usage experience.
[0012] Preferably, the second water inlet seat forms a water storage space, the water outlet seat forms a mixing space, and the two sides of the second water inlet seat form output ports connecting to the water storage space, while the two sides of the water outlet seat form input ports connecting to the mixing space. The two ends of the second delivery pipe are respectively connected to the output port and the input port. Through the above improvements, the water storage space temporarily stores the incoming water and diverts it to the two second delivery pipes through the output ports on both sides, ensuring that the water inlet pressure of the two pipes is balanced and the flow distribution is uniform. The mixing space gathers the two water flows and outputs them stably, effectively avoiding turbulent splashing. This not only improves the smoothness of the water output but also ensures the stability of large water volume output, significantly improving the user's water usage experience.
[0013] Preferably, the first water inlet seat is annularly disposed around the outer periphery of the water outlet valve, and the outer periphery of the water outlet valve forms a second water outlet hole that connects to the first water inlet seat. The outer periphery of the water outlet valve is provided with a first sealing ring and a second sealing ring that abut against the inner wall of the first water inlet seat. The second water outlet hole is disposed between the first sealing ring and the second sealing ring. Through these improvements, the first water inlet seat is annularly disposed around the outer periphery of the water outlet valve, allowing the second water outlet hole on the side wall of the water outlet valve to directly connect to the first water inlet seat, resulting in a more compact structure. Furthermore, the first sealing ring and the second sealing ring abut against the inner wall of the first water inlet seat, sealing the second water outlet hole between them, forming an independent and sealed annular water inlet channel. This effectively prevents water overflow and cross-contamination, ensuring reliable water circuit connection. It also simplifies the assembly process and improves sealing performance and product lifespan.
[0014] Preferably, the water inlet is provided with a first positioning post, and the bottom of the first water inlet seat is circumferentially arranged with first positioning grooves for the first positioning post to be inserted. With the above improvements, when the first water outlet arm is rotated and adjusted, the first positioning post is engaged in the corresponding positioning groove, generating stable positioning damping, effectively preventing the water outlet arm from shifting due to water flow impact or accidental contact, ensuring that the water outlet direction remains stable, which not only ensures the flexibility of angle adjustment, but also improves the positioning reliability during use, thereby enhancing the user experience.
[0015] Preferably, the first water outlet arm is provided with a connecting boss, and the connecting boss is provided with a rotating groove for the second water inlet seat to be inserted. The bottom of the second water outlet arm is provided with a second positioning post, and the connecting boss is provided with second positioning grooves arranged at intervals around the circumference for the second positioning post to be inserted. Through the above improvements, the second positioning post cooperates with the circumferentially arranged second positioning grooves, and can be locked into the corresponding positioning groove after the angle is adjusted, generating stable damping. This effectively prevents the second water outlet arm from deflecting due to water backflow or external force contact, ensuring that the water outlet direction is accurately maintained. This not only ensures the flexibility of multi-angle adjustment, but also significantly improves the positioning stability during use.
[0016] Preferably, a sterilizing lamp is installed on the second water inlet pipe. With the above improvements, the sterilizing lamp installed on the second water inlet pipe can perform online real-time sterilization treatment on the purified water flowing through the pipe, effectively removing bacteria and microorganisms that may grow in the water, further improving the quality of the effluent, making full use of the conveying path from the filter cartridge to the faucet, and achieving secondary sterilization without increasing the space occupation.
[0017] Compared with the prior art, the present invention has the following advantages and beneficial effects:
[0018] By setting up a dual-inlet, dual-outlet water circuit structure, water first enters the first inlet pipe inside the base, and then flows into the first delivery channel inside the outlet valve. When the faucet is turned on, the water flows through the output end of the first delivery channel into the return pipe, and then to the inlet end of the filter element assembly for filtration. The filtered clean water flows out from the outlet end of the filter element assembly, enters the inlet end of the second inlet pipe, and then flows back to the second delivery channel inside the outlet valve. Finally, the clean water enters the outlet section through the output end of the second delivery channel, and flows out from the drain hole simultaneously through the first and second outlet channels inside the outlet section for user use. This effectively solves the problem of long-term pressure on traditional faucet pipes. When the faucet is turned off, the outlet valve directly isolates the first and second delivery channels inside, and water cannot enter the filter element assembly through the outlet valve. This relieves the static pressure on the inlet end of the filter element assembly from the system's static pressure, greatly reducing the risk of slow seepage or leakage caused by the fatigue and aging of the sealing ring, significantly improving safety. In addition, the dual-outlet structure enables a large flow rate, fully meeting the large water demand of daily washing scenarios such as washing vegetables and dishes. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] It should be understood that although the terms upper, middle, lower, top, one end, etc., appear in this document to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish the elements from each other for ease of understanding, and are not used to define any directional or sequential restrictions.
[0034] like Figure 1 , Figure 2 , Figure 3 As shown, a dual-inlet, dual-outlet water purifier includes a base 1, on which a filter assembly 2 and a water faucet 3 are mounted. The water faucet 3 includes an inlet section 101 and an outlet section 102. The outlet section 102 is provided with a drain hole 201. The inlet section 101 is provided with an outlet valve 202. The outlet valve 202 is provided with a first conveying channel 203 and a second conveying channel 204. The outlet valve 202 can be rotated to connect or disconnect the first conveying channel 203 and the second conveying channel 204.
[0035] Specifically, the base 1 is provided with a first water inlet pipe 205, a second water inlet pipe 206, and a return pipe 207. The first water inlet pipe 205 is connected to the water inlet end of the first conveying channel 203. The output end of the first conveying channel 203 is connected to the return pipe 207. The water outlet end of the return pipe 207 is connected to the water inlet end of the filter element assembly 2. The water outlet end of the filter element assembly 2 is connected to the water inlet end of the second water inlet pipe 206. The water outlet end of the second water inlet pipe 206 is connected to the water inlet end of the second conveying channel 204. The water outlet end of the second conveying channel 204 is connected to the water outlet section 102. The water outlet section 102 is provided with a first water outlet channel 208 and a second water outlet channel 209 that are connected to the drain hole 201.
[0036] During the entire water flow process, water first enters the first inlet pipe 205 inside the base 1, then flows into the first conveying channel 203 inside the outlet valve 202. When the faucet is turned on, the water flows through the output end of the first conveying channel 203 into the return pipe 207, and then to the inlet end of the filter element assembly 2 for filtration. The filtered clean water flows out from the outlet end of the filter element assembly 2, enters the inlet end of the second inlet pipe 206, and then flows back to the second conveying channel 204 inside the outlet valve 202. Finally, the clean water enters the outlet section 102 through the output end of the second conveying channel 204. The water flows out from the drain hole 201 simultaneously through the first water outlet channel 208 and the second water outlet channel 209 inside the water outlet section 102 for user use. When the faucet is closed, the water outlet valve 202 directly cuts off the first delivery channel 203 and the second delivery channel 204. The water inlet end of the filter element assembly 2 no longer bears the static pressure of the system, effectively avoiding the risk of slow seepage or leakage caused by the fatigue and aging of the sealing ring, significantly improving the safety of product use. In addition, the dual-outlet structure realizes the function of large flow water, which fully meets the large water demand of daily washing scenarios such as washing vegetables and washing dishes.
[0037] like Figure 2 As shown, preferably, the second water inlet pipe 206 is equipped with a sterilizing lamp 609, which can perform online instant sterilization treatment on the purified water flowing through the pipe, effectively removing bacteria and microorganisms that may grow in the water, further improving the quality of the effluent, making full use of the conveying path from the filter cartridge to the faucet, and achieving secondary sterilization without increasing the space occupation.
[0038] like Figure 3 , Figure 4 , Figure 7 , Figure 8 As shown, to further explain the structure of the outlet valve 202, the outlet valve 202 is located on the top of the water inlet body 301, and the outlet section 102 can be controlled to discharge water through the outlet valve 202.
[0039] Specifically, the water outlet valve 202 includes an inlet body 301 and an outlet knob 302 mounted on the inlet body 301. The bottom of the inlet body 301 is provided with a first inlet hole 303, a second inlet hole 304, and a first outlet hole 305. A second outlet hole 306 is formed on the side wall of the inlet body 301. The outlet knob 302 is provided with a first connecting groove 307 for connecting the first inlet hole 303 and the first outlet hole 305, and a second connecting groove 308 for connecting the second inlet hole 304 and the second outlet hole 306. The first connecting groove 307 connects the first inlet hole 303 and the first outlet hole 305. The first conveying channel 203 is formed by the 05, and the second connecting groove 308 connects the second water inlet 304 and the second water outlet 306 to form the second conveying channel 204. Turning the water outlet knob 302 can simultaneously control the opening and closing of the two water paths. The first connecting groove 307 and the second connecting groove 308 are independently set inside the knob, corresponding to the raw water and purified water channels respectively, realizing the physical isolation of the two water flows, preventing water mixing and pollution. In addition, the bottom and side wall of the water inlet body 301 are three-dimensionally perforated, which effectively shortens the water flow path, makes the entire water circuit structure more compact, reduces the number of pipe joints, effectively reduces the risk of water leakage, and improves the reliability and service life of the product.
[0040] Furthermore, the outlet valve 202 has an open state and a closed state. When it is in the open state, the two ends of the first connecting groove 307 are connected to the first inlet hole 303 and the first outlet hole 305 respectively, and the two ends of the second connecting groove 308 are connected to the second inlet hole 304 and the second outlet hole 306 respectively. When it is in the closed state, the two ends of the first connecting groove 307 are staggered and sealed with the first inlet hole 303 and the first outlet hole 305 respectively, and the two ends of the second connecting groove 308 are staggered and sealed with the second inlet hole 304 and the second outlet hole 306 respectively, thus preventing water leakage and simplifying the overall water circuit structure.
[0041] The output end of the second connecting groove 308 is located at the center of the water outlet knob 302. The input end of the second connecting groove 308, as well as the output and input ends of the first connecting groove 307, are arranged at intervals along the circumference of the water outlet knob 302. The input end of the second water inlet 304 is located at the center of the water inlet body 301 and is opposite to the output end of the second connecting groove 308. The first water inlet 303, the second water inlet 304, and the first water outlet 305 correspond to the output and input ends of the first connecting groove 307 and the input end of the second connecting groove 308, respectively.
[0042] Preferably, a sealing gasket is provided at the bottom of the water outlet knob 302. The sealing gasket is arranged in a ring at the output end and input end of the first connecting groove 307 and the second connecting groove 308 to ensure the stability of the water outlet knob 302 during rotation.
[0043] like Figure 3 , Figure 5 , Figure 6 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 As shown, as a further explanation of the embodiment of the water outlet 102, the water outlet 102 includes a first water outlet arm 401 horizontally mounted on the water outlet 102, and a second water outlet arm 402 horizontally mounted on the first water outlet arm 401. The first water outlet arm 401 can rotate horizontally around the water outlet 102, and the second water outlet arm 402 can rotate horizontally independently relative to the first water outlet arm 401. The two together form a multi-angle folding and extension mechanism, which enables the water outlet to cover a larger area, thereby improving the user experience.
[0044] Specifically, the drain hole 201 is located on the second water outlet arm 402 and is positioned away from the first water outlet arm 401. The water inlet end of the second water outlet arm 402 is provided with a second water inlet seat 406, and the water outlet end of the second water outlet arm 402 is provided with a water outlet seat 407. The second water inlet seat 406 is connected to two sides of the second delivery pipe 408, and the second delivery pipe 408 is connected to the water outlet seat 407. The two second delivery pipes 408 respectively form the first water outlet channel 208 and the second water outlet channel 209, forming a dual-channel synchronous water supply structure, which greatly increases the water flow rate and meets the needs of large water volume scenarios such as quick water access in the kitchen and washing large items.
[0045] The first water inlet arm 401 is provided with a first water inlet seat 403 at its inlet end, which is rotatably mounted on the water outlet part 102. The first water outlet arm 401 is provided with a water outlet connector 404 at its outlet end. A first delivery pipe 405 is provided inside the first water outlet arm 401, connecting the first water inlet seat 403 and the water outlet connector 404. A second water inlet seat 406 is connected to the water outlet connector 404. The first water inlet seat 403, the water outlet connector 404, the second water inlet seat 406, and the water outlet seat 407 work together to ensure reliable water flow at the rotating connection of the double rotating arms, and smooth and unobstructed water flow at the movable joint, thus improving the user's water usage experience.
[0046] Furthermore, the second inlet seat 406 forms a water storage space 501, and the outlet seat 407 forms a mixing space 502. Output ports 503 connecting the water storage space 501 are formed on both sides of the second inlet seat 406, and input ports 504 connecting the mixing space 502 are formed on both sides of the outlet seat 407. The two ends of the second delivery pipe 408 are connected to the output ports 503 and the input ports 504, respectively. The water storage space 501 temporarily stores the incoming water and distributes it to the two second delivery pipes 408 through the output ports 503 on both sides, ensuring balanced water pressure and uniform flow distribution between the two pipes. The mixing space 502 collects the two water flows and outputs them stably, effectively avoiding turbulent splashing. This not only improves the smoothness of the water flow but also ensures the stability of large-volume water output, significantly improving the user's water experience.
[0047] In addition, the first water inlet seat 403 is arranged around the outer periphery of the water outlet valve 202. The outer periphery of the water outlet valve 202 forms a second water outlet hole 306 that connects to the first water inlet seat 403. The outer periphery of the water outlet valve 202 is provided with a first sealing ring 601 and a second sealing ring 602 that abut against the inner wall of the first water inlet seat 403. The second water outlet hole 306 is located between the first sealing ring 601 and the second sealing ring 602. The first water inlet seat 403 is arranged around the outer periphery of the water outlet valve 202, so that the second water outlet hole 306 on the side wall of the water outlet valve 202 directly connects to the first water inlet seat 403, making the structure more compact. The first sealing ring 601 and the second sealing ring 602 abut against the inner wall of the first water inlet seat 403 respectively, sealing the second water outlet hole 306 between them, forming an independent and sealed annular water inlet channel, effectively preventing water overflow and cross-flow, ensuring reliable water circuit connection, simplifying the assembly process, improving sealing performance and product service life.
[0048] The water inlet 101 is provided with a first positioning post 603, and the bottom of the first water inlet seat 403 is circumferentially arranged with first positioning grooves 604 for the first positioning post 603 to be inserted. When the first water outlet arm 401 is rotated and adjusted, the first positioning post 603 is engaged in the corresponding positioning groove, generating stable positioning damping, which effectively prevents the water outlet arm from shifting due to water flow impact or accidental contact, ensuring that the water outlet direction remains stable. This not only ensures the flexibility of angle adjustment, but also improves the positioning reliability during use, thereby enhancing the user experience.
[0049] The first water outlet arm 401 is provided with a connecting boss 605, and the connecting boss 605 is provided with a rotating groove 606 for the second water inlet seat 406 to be inserted. The bottom of the second water outlet arm 402 is provided with a second positioning post 607, and the connecting boss 605 is provided with second positioning grooves 608 arranged circumferentially for the second positioning post 607 to be inserted. The second positioning post 607 cooperates with the circumferentially arranged second positioning grooves 608, and can be locked into the corresponding positioning groove after the angle is adjusted, generating stable damping, effectively preventing the second water outlet arm 402 from deflecting due to water backflow or external force, ensuring that the water outlet direction is accurately maintained, which not only ensures the flexibility of multi-angle adjustment, but also significantly improves the positioning stability during use.
[0050] Preferably, springs are fitted on the first positioning post 603 and the second positioning post 607 so that the first positioning post 603 and the second positioning post 607 always have a tendency to move toward the first positioning groove 604 and the second positioning groove 608.
[0051] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
