Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0021] Reference Figures 1 to 16 As shown in the figure, this application embodiment provides a faucet, including a faucet body 100, a water outlet pipe 200, and a water outlet connector 300.

[0022] One end of the water outlet pipe 200 is located on the faucet body 100, and the faucet body 100 is provided with a purified water flow channel 110 for purified water flow and a tap water flow channel 120 for tap water flow; the water outlet pipe 200 is provided with a purified water channel 210 connected to the purified water flow channel 110 and a tap water channel 220 connected to the tap water flow channel 120; the other end of the water outlet pipe 200 is provided with a tap water outlet 230 connected to the tap water channel 220.

[0023] The water outlet connector 300 is located at the other end of the water outlet pipe 200, and the water outlet connector 300 is provided with a clean water outlet 310 that communicates with the clean water channel 210. The water outlet connector 300 can rotate relative to the water outlet pipe 200 around the central axis of the water outlet pipe 200, so that the water outlet connector 300 can switch between a clean water outlet position with the clean water outlet 310 facing downward and a clean water rinsing position with the clean water outlet 310 facing upward.

[0024] In specific implementation, refer to Figures 6 to 10 As shown, one end of the water outlet pipe 200 can be connected to the faucet body 100 by fastener limiting connection, threaded connection, or snap-fit. Two main flow channels can be formed within the faucet body 100: one is a purified water flow channel 110 for purified water, and the other is a tap water flow channel 120 for tap water. The tap water can be cold water, hot water, or a mixture of both, and the water temperature can be set according to actual needs.

[0025] The outlet pipe 200 is also equipped with two main flow channels, one of which is a purified water channel 210 connected to the purified water channel 110, and the other is a tap water channel 220 connected to the tap water channel 120. The outlet pipe 200 is also equipped with a tap water outlet 230.

[0026] When tap water is needed, please refer to the following: Figure 10 As shown in the water flow path, external tap water flows through tap water channel 120 to tap water channel 220 and then is discharged through tap water outlet 230 to realize the tap water dispensing operation. That is, at this time, the faucet is in the position shown in the diagram. Figure 10 The water dispensing mode shown is for tap water.

[0027] The other end of the water outlet pipe 200 is equipped with a water outlet connector 300, and the water outlet connector 300 is equipped with a clean water outlet 310. When clean water is required, refer to... Figure 7 The water flow path shown indicates that after purification, external water flows from the purified water channel 110 to the purified water channel 210 and is discharged through the purified water outlet 310, realizing the purified water dispensing operation. That is, the faucet is in the purified water dispensing mode at this time.

[0028] In this embodiment, the water outlet connector 300 and the water outlet pipe 200 are configured to be rotatably connected, that is, the water outlet connector 300 can rotate relative to the water outlet pipe 200 around the central axis of the water outlet pipe 200, so that the water outlet connector 300 can switch between a water outlet position with the water outlet 310 facing downward and a water rinsing position with the water outlet 310 facing upward.

[0029] For example, refer to Figure 1 and Figure 2 As shown, when using purified water for cooking or drinking, the water outlet 300 can be rotated so that the purified water outlet 310 faces downwards, allowing purified water to flow out downwards for easy collection. (Refer to...) Figure 3 and Figure 4 As shown, when it is necessary to use purified water for rinsing, simply rotate the water outlet 300 so that the purified water outlet 310 is upward, so that purified water can be sprayed upward through the purified water outlet 310 to spray purified water into the user's mouth for rinsing, thereby making the rinsing operation more convenient.

[0030] For example, the tap water outlet 230 can be set on the bottom surface of the water outlet pipe 200 so that water can flow downwards, making it convenient for users to collect water or use tap water for washing and other operations.

[0031] In practice, the purified water channel 210 and the tap water channel 220 can be two parallel and independent channels to facilitate the arrangement of the channels in the outlet pipe 200. Similarly, the purified water channel 110 and the tap water channel 120 can also be set as two parallel and independent channels to facilitate the arrangement of the channels within the faucet body 100.

[0032] The faucet in this embodiment includes a faucet body 100, a water outlet pipe 200, and a water outlet connector 300. One end of the water outlet pipe 200 is located on the faucet body 100, and the faucet body 100 contains a purified water channel 110 for purified water flow and a tap water channel 120 for tap water flow. The water outlet pipe 200 contains a purified water channel 210 connected to the purified water channel 110 and a tap water channel 220 connected to the tap water channel 120. The other end of the water outlet pipe 200 has a tap water outlet 230 connected to the tap water channel 220. The water outlet connector 300 is located at the other end of the water outlet pipe 200 and has a purified water outlet 310 connected to the purified water channel 210. Thus, tap water can be discharged through the tap water channel 120, the tap water channel 220, and the tap water outlet 230 when needed. When purified water is needed, it can be discharged through the purified water flow channel 110, purified water channel 210, and purified water outlet 310, allowing different water to be discharged through different water paths, thus achieving multi-functional water dispensing operation of the faucet and meeting the user's needs. Simultaneously, in this embodiment, the faucet's outlet connector 300 can rotate relative to the outlet pipe 200 around the central axis of the outlet pipe 200, allowing the outlet connector 300 to switch between a purified water outlet 310 facing downwards and a purified water rinsing position with the outlet 310 facing upwards. In other words, when purified water is needed for cooking or drinking, the outlet connector 300 can be rotated so that the purified water outlet 310 faces downwards, allowing purified water to flow downwards for easy collection. When rinsing with purified water is needed, simply rotate the water outlet 300 to raise the purified water outlet 310, allowing purified water to spray upwards into the user's mouth for rinsing, thus making the rinsing operation more convenient. Therefore, the faucet in this embodiment integrates tap water dispensing, purified water dispensing in normal mode, and purified water rinsing, offering rich functionality and convenient function switching.

[0033] Reference Figure 2 and Figure 4 As shown, in some embodiments, the water outlet 310 is also tilted away from the faucet body.

[0034] In practice, when a user needs to rinse their mouth with purified water, in order to make it easier for the water sprayed from the purified water outlet 310 to be sprayed into the user's mouth, the central axis of the purified water outlet 310 can be tilted towards the end away from the water outlet 200 along the direction from the water outlet pipe 200 to the faucet body 100. This allows the purified water sprayed from the purified water outlet 310 to tilt outward (i.e. towards the user's location) at a certain angle, rather than spraying straight upward. This makes it easier for the purified water to be sprayed into the user's mouth in a direction closer to the user, thereby improving the user experience.

[0035] Reference Figure 7 and Figure 10 As shown, in some embodiments, the purified water channel 210 is located inside the tap water channel 220, and the end of the purified water channel 210 near the water outlet connector 300 is rotatably connected to the water outlet connector 300.

[0036] This arrangement can effectively utilize the space within the water outlet pipe 200, rationally arrange the purified water channel 210 and the tap water channel 220, and set the purified water channel 210 to be rotatably connected to the water outlet connector 300, so that the water outlet connector 300 connected to the purified water channel 210 can rotate freely without being restricted, that is, it will not be affected by the purified water channel 210.

[0037] The specific rotary connection can be achieved by using an insertion rotary connection or by using a hollow coupling to achieve the rotary connection between the two.

[0038] In practice, a water pipe can be inserted into the outlet pipe 200, and the inner cavity of the water pipe forms a clean water channel 210. The end of the water pipe near the outlet connector 300 is rotatably connected to the outlet connector 300, and the space between the outer wall of the water pipe and the inner wall of the outlet pipe 200 forms a tap water channel 220.

[0039] Reference Figure 2 , Figure 4 and Figure 11 As shown, in some embodiments, one end of the water outlet connector 300 is inserted into the water outlet pipe 200, and a stop structure 400 is provided between the water outlet connector 300 and the water outlet pipe 200.

[0040] In practice, to make it easier to remind the user that the water outlet connector 300 has been rotated to the required position, a stop structure 400 can be provided between the water outlet connector 300 and the water outlet pipe 200.

[0041] For example, when the required position is the purified water outlet position, when the water outlet connector 300 is rotated to the position where the purified water outlet 310 is facing downwards, the water outlet connector 300 is not easy to continue rotating in this position, that is, it requires relatively large force to continue rotating. This can achieve a sense of gear position to remind the user that the water outlet connector 300 has been rotated to the purified water outlet position, thereby improving the user experience.

[0042] For example, when the desired position is the water rinsing position, when the water outlet 300 is rotated to the position where the water outlet 310 is facing upwards, the water outlet 300 is not easy to continue rotating in this position, that is, it requires relatively large force to continue rotating. This can achieve a sense of gear position to remind the user that the water outlet 300 has been rotated to the water rinsing position, thereby improving the user experience.

[0043] Reference Figure 2 , Figure 4 and Figure 11 As shown, in some embodiments, the gear position structure 400 includes an elastic abutment structure 410 and a stop portion 420. One of the elastic abutment structure 410 and the stop portion 420 is provided in the water outlet connector 300, and the other of the elastic abutment structure 410 and the stop portion 420 is provided in the water outlet pipe 200. The elastic abutment structure 410 can cooperate with the stop portion 420 to stop when the water outlet connector 300 is rotated to either the purified water outlet position or the purified water rinsing position.

[0044] In practice, to remind the user that the water outlet connector 300 has been rotated to the desired position, the elastic abutment structure 410 and the stop part 420 cooperate to stop it. In this position, the water outlet connector 300 is not easy to continue rotating, that is, it requires relatively large force to continue rotating. This can achieve a sense of position, reminding the user that the water outlet connector 300 has been rotated to the desired position, thereby improving the user experience.

[0045] Reference Figure 2 , Figure 4 and Figure 11 As shown, in some embodiments, the elastic abutment structure 410 includes an elastic member 411 and an abutment member 412. One end of the elastic member 411 is connected to the outer wall of the water outlet connector 300, and the abutment member 412 is disposed at the other end of the elastic member 411. The stop portion 420 includes at least two stop grooves that engage with the abutment member 412. The at least two stop grooves are disposed on opposite upper and lower sides of the inner wall of the water outlet pipe 200.

[0046] For example, when the required position is the purified water outlet position, when the water outlet connector 300 rotates, the abutment 412 compresses the elastic element 411. When the water outlet connector 300 rotates to the position where the purified water outlet 310 faces downwards, in this position, the abutment 412 moves towards the stop part 420 under the elastic force of the elastic element 411 and engages with the stop part 420. At this time, the water outlet connector 300 is not easy to continue rotating, that is, it requires relatively large force to continue rotating. This can achieve a sense of gear position, and when the abutment 412 engages with the stop groove, it will make a "click" sound to remind the user that the water outlet connector 300 has been rotated to the purified water outlet position, thereby improving the user experience.

[0047] For example, when the desired position is the water rinsing position, when the water outlet 300 rotates, the abutment 412 compresses the elastic element 411. When the water outlet 300 rotates to the position where the water outlet 310 faces upward, the abutment 412 moves towards the stop 420 under the elastic force of the elastic element 411 and engages with the stop groove. At this time, the water outlet 300 is not easy to continue rotating, that is, it requires relatively large force to continue rotating. This can achieve a sense of position, and when the abutment 412 engages with the stop groove, it will make a "click" sound to remind the user that the water outlet 300 has been rotated to the water rinsing position, thereby improving the user experience.

[0048] In this embodiment, two stop slots can be provided, arranged opposite each other. For example, when the water outlet connector 300 is rotated to the position where the purified water outlet 310 faces downward, the abutment 412 engages in the lower stop slot. When the water outlet connector 300 is rotated to the position where the purified water outlet 310 faces upward, the abutment 412 engages in the upper stop slot. This allows the water outlet connector 300 to engage with the corresponding stop slot regardless of whether the purified water outlet 310 is in the purified water outlet position or the purified water rinsing position, providing a sense of engagement.

[0049] For example, the elastic element 411 can be a spring or other component with elastic deformation capability. The abutment element 412 can be a marble or a bullet.

[0050] Reference Figure 2 , Figure 4 and Figure 11 As shown, in some embodiments, the outer wall of the water outlet connector 300 is provided with an installation hole 320, and the elastic abutment structure 410 is provided in the installation hole 320.

[0051] In other words, in this embodiment, the elastic abutment structure 410 can be set on the water outlet connector 300, and the stop part 420 can be set inside the water outlet pipe 200, which facilitates manufacturing and processing.

[0052] Furthermore, the outer wall of the water outlet connector 300 is provided with a mounting hole 320. Placing the elastic abutment structure 410 in the mounting hole 320 can not only save the radial dimension of the entire structure, but also guide the movement of the elastic abutment structure 410.

[0053] Reference Figure 2 , Figure 4 , Figure 11 and Figure 16 As shown, in some embodiments, the other end of the water outlet pipe 200 is provided with a bend joint 240 that communicates with the tap water channel 220 and the purified water channel 210. A bushing 250 is provided on the bend joint 240, the water outlet joint 300 is inserted into the bushing 250, and the stop part 420 is provided on the inner edge of the bushing 250.

[0054] The inner edge of the bushing 250 is provided with a first limiting part 251, and the outer wall of the elbow joint 240 is provided with a second limiting part 241. The first limiting part 251 and the second limiting part 241 cooperate to restrict the bushing 250 from rotating relative to the elbow joint 240.

[0055] In practice, the bushing 250 and the elbow joint 240 are relatively fixed, meaning that the bushing 250 does not rotate with the rotation of the outlet joint 300. At this time, the first limiting part 251 on the bushing 250 can be a slit, and the second limiting part 241 on the outer wall of the elbow joint 240 is also a slit, that is, the relative rotation of the two is restricted by the cooperation of the two slits.

[0056] Alternatively, in other implementations, one of the first limiting part 251 and the second limiting part 241 is a limiting buckle, and the other is a limiting slot that cooperates with the limiting buckle.

[0057] Reference Figure 11 As shown, in some embodiments, an annular groove 330 is provided on the outer wall of the water outlet connector 300, and a connector 340 that rotates and engages with the water outlet connector 300 is provided in the annular groove 330. The connector 340 is connected to the water outlet pipe 200.

[0058] In practice, to facilitate the rotational engagement between the water outlet connector 300 and the water outlet pipe 200, an annular groove 330 can be provided on the water outlet connector 300, and a connector 340 can be provided on the annular groove 330. That is, the water outlet connector 300 can rotate relative to the connector 340, and the connector 340 is connected to the water outlet pipe 200, meaning that the connector 340 remains relatively stationary.

[0059] Alternatively, in other implementations, the water outlet connector 300 and the water outlet pipe 200 can be rotatably connected by the cooperation of ball bearings and grooves.

[0060] For example, connector 340 includes a non-closed annular snap fastener to facilitate opening both ends of the non-closed annular snap fastener and engaging it in the annular groove 330. For example, the non-closed annular snap fastener can be a C-type snap fastener such as a semi-circular snap fastener or a three-quarter circular snap fastener.

[0061] Reference Figure 11 As shown, in some embodiments, the water outlet pipe 200 is provided with a first connection hole, and the connector 340 is provided with a second connection hole. The water outlet pipe 200 and the connector 340 are connected by fasteners 350 passing through the first connection hole and the second connection hole.

[0062] For example, one of the first connecting hole and the second connecting hole can be a threaded hole, and the other can be a smooth hole, and the fastener 350 can be a screw or bolt. Alternatively, both the first connecting hole and the second connecting hole can be smooth holes, and the fastener 350 can be a fastening pin.

[0063] In specific implementation, the first connecting hole and the second connecting hole can both be one or both can be at least two. When both are provided with at least two, the at least two first connecting holes are spaced apart along the circumference of the connector 340, and the at least two second connecting holes correspond one-to-one with the first connecting holes. The fasteners 350 are also provided with at least two and correspond one-to-one with the first and second connecting holes, so as to further improve the connection stability between the water outlet pipe 200 and the connector 340 through the cooperation of the at least two first connecting holes, the second connecting holes and the fasteners 350.

[0064] In a specific implementation, the water outlet connector 300 may include a purified water pipe 360, a purified water interface 370, and a purified water housing 380. The purified water pipe 360 ​​is provided with an annular groove 330, the purified water interface 370 is provided on the purified water pipe 360, and the purified water outlet 310 is provided on the purified water interface 370. The purified water housing 380 covers the portion of the purified water pipe 360 ​​located outside the water outlet pipe 200, and the purified water housing 380 is provided with a clearance opening at a position corresponding to the purified water interface 370, allowing the purified water interface 370 to pass through.

[0065] Reference Figures 1 to 10 As shown, in some embodiments, the faucet body 100 includes a body shell 130 and an intermediate valve core seat 140 disposed within the body shell 130.

[0066] The main body shell 130 is provided with a first water inlet pipe 150 for external clean water to flow in, a second water inlet pipe 160 for external cold water to flow in, and a third water inlet pipe 170 for external hot water to flow in.

[0067] The intermediate valve core seat 140 has a first water inlet channel 141, a second water inlet channel 142, a third water inlet channel 143, a first water outlet channel 144, and a second water outlet channel 145. The first water inlet pipe 150, the first water inlet channel 141, and the first water outlet channel 144 are connected to form a clean water flow channel 110. The second water inlet pipe 160, the third water inlet pipe 170, the second water inlet channel 142, the third water inlet channel 143, and the second water outlet channel 145 are connected to form a tap water flow channel 120.

[0068] In practice, when tap water is needed, the tap water channel 120 can be kept open while the clean water channel 110 is disconnected. External cold water flows through the second inlet pipe 160 to the second inlet channel 142, and external hot water flows through the third inlet pipe 170 to the third inlet channel 143. After mixing in the intermediate valve core seat 140, the hot water flows through the second outlet channel 145 to the tap water channel 220 and is then discharged through the tap water outlet 230, thus realizing the tap water output.

[0069] When purified water is needed, the purified water channel 110 can be kept open while the tap water channel 120 is disconnected. The external purified water flows through the first inlet pipe 150 to the first inlet channel 141, and then through the first outlet channel 144 to the purified water channel 210 before being discharged through the purified water outlet 310.

[0070] Reference Figures 1 to 6 As shown, in some embodiments, the faucet also includes a water purification valve core 500. The water purification valve core 500 includes a water purification valve core flow channel and a first inlet and a first outlet located at both ends of the water purification valve core flow channel. The first inlet is connected to the first water inlet channel 141, and the first outlet is connected to the first water outlet channel 144. The water purification valve core 500 is used to control the on / off state between the first inlet and the first outlet.

[0071] The faucet also includes a mixing valve core 600, which has a mixing channel and two inlets and a mixing outlet located in the mixing channel; the second water inlet channel 142 and the third water inlet channel 143 are respectively connected to the two inlets, and the mixing outlet is connected to the second water outlet channel 145. The mixing valve core 600 is used to control the on / off connection between the two inlets and the mixing outlet.

[0072] In other words, when tap water is needed, the mixing valve core 600 controls the connection between the two inlets and the mixing outlet, while the purification valve core 500 controls the disconnection between the first inlet and the first outlet. At this time, external cold water flows through the second inlet pipe 160 to the second inlet channel 142 and then flows into the mixing channel through one inlet. External hot water flows through the third inlet pipe 170 to the third inlet channel 143 and then flows into the mixing channel through another inlet. After mixing in the mixing channel, the water flows through the second outlet channel 145 to the tap water channel 220 and then is discharged through the tap water outlet 230, thus achieving tap water output. Specifically, the outlet water temperature can be adjusted by adjusting the mixing valve core 600. The specific adjustment structure and principle are described in relevant technical documents and will not be elaborated here.

[0073] When purified water is needed, the mixing valve core 600 controls the disconnection between the two inlets and the mixing outlet, while the purified water valve core 500 controls the connection between the first inlet and the first outlet. At this time, the external purified water flows through the first inlet pipe 150 to the first inlet channel 141, then through the first inlet to the purified water valve core channel, then through the first outlet and into the first outlet channel 144, then into the purified water channel 210 and finally out through the purified water outlet 310.

[0074] In practice, a valve core adapter 700 is provided between either the second water inlet channel 142 or the third water inlet channel 143 and the mixing valve core 600. The specific requirement for the valve core adapter 700 can be determined based on the height of the mixing valve core 600 or the shape of the faucet body 100.

[0075] Specifically, the valve core adapter 700 may have a first adapter inlet channel 710 connected to the second inlet channel 142, a second adapter inlet channel 720 connected to the third inlet channel 143, and an adapter outlet channel 730 connecting the first adapter inlet channel 710, the second adapter inlet channel 720, and the mixing valve core 600.

[0076] In practice, a water purifier 800 is installed on the first water inlet pipe 150 to purify the water and form clean water that flows into the first water inlet channel 141.

[0077] In practice, an aerator 900 is installed at the tap water outlet 230 to select the water flow rate according to actual needs.
