The switch assembly 2 is arranged at the water outlet end 801 of the water pipe 8 and is connected with the water pipe 1, so as to control the water purifying water in the water pipe 1.

[0066] Therefore, the water purifying device is arranged on the faucet, the direct drinking water purifying output function of the faucet is added, the integrated supply of cold water, hot water and water purifying water of the faucet is effectively realized, and compared with the prior art, the water purifying water in the water purifying device is controlled by the independent switch assembly 2, the overall structure of the faucet is effectively simplified, and the manufacturing cost of the faucet is reduced.

[0067] In one embodiment, the water pipe 8 has an outlet end 801 and an inlet end 802. The water purification pipe 1 is disposed inside the water pipe 8, and a flow channel 800 is formed between the water pipe 8 and the water purification pipe 1.

[0068] Specifically, such as Figures 1 to 4 As shown in the embodiment of this application, the water purification pipe 1 is disposed within the water pipe 8, and the water pipe 8 is divided into three independent water supply circuits: a cold water supply circuit, a hot water supply circuit, and a purified water supply circuit. The cold water supply circuit and the hot water supply circuit are formed by a flow channel 800 between the water pipe 8 and the purified water pipe 1. The flow channel 800 can be a single channel, allowing the cold water supply circuit and the hot water supply circuit to be the same channel; alternatively, the flow channel 800 can be two channels, used to respectively form the cold water supply circuit and the hot water supply circuit. The flow channel 800 has a first opening 8001 and a second opening 8002. The first opening 8001 is located at the outlet end 801 of the water pipe 8, allowing cold and hot water to enter the flow channel 800 for transportation, and allowing purified water to enter the purified water pipe 1 for transportation. The second opening 8002 is located at the inlet end 802, used to output cold water, hot water, and purified water.

[0069] The faucet also includes a faucet assembly 9, which can be connected to the water pipe 8 to deliver cold water, hot water, and purified water to the water pipe 8. The faucet assembly 9 is equipped with a purified water inlet pipe 901 and cold / hot water inlet pipes 902. The purified water inlet pipe 901 is connected to the inlet 102 of the purified water pipe 1 via a purified water inlet connector 13 to improve the reliability of the connection between the purified water inlet pipe 901 and the inlet 102 of the purified water pipe 1.

The hot and cold water inlet pipe 902 can also be a single pipe, so that both cold and hot water are transported through the hot and cold water inlet pipe 902. In this case, the hot and cold water inlet pipe 902 is connected to the second opening 8002 of the flow channel 800 to ensure the transport efficiency of cold and hot water.

[0070] In addition, the faucet described in this application also includes a quick-connect fitting 14 for a water purifier pipe. The quick-connect fitting 14 can connect the water purifier inlet connector 13 to the inlet 102 of the water purifier pipe 1 to further improve the sealing performance between the water purifier inlet pipe 901 and the inlet 102 of the water purifier pipe 1; or, the quick-connect fitting 14 can also connect the switch assembly 2 to the outlet 101 of the water purifier pipe 1 to further improve the sealing performance between the switch assembly 2 and the outlet 101 of the water purifier pipe 1.

[0071] Furthermore, the faucet described in this application also includes a first sealing element 3 and a first anti-slip element 4. The first sealing element 3 is disposed between the water pipe 8 and the switch assembly 2 to ensure the sealing performance between the water pipe 8 and the switch assembly 2. The first anti-slip element 4 is disposed between the water pipe 8 and the switch assembly 2 to prevent the rotating shaft 203 from rubbing against other metal parts in the faucet when rotating, thereby improving the stability and reliability of the rotating shaft 203.

[0072] In addition, the faucet described in this application also includes a second sealing element 10, a second anti-slip element 11, and an anti-wear ring 12. The second sealing element 10 is disposed between the water pipe 8 and the faucet assembly 9 to ensure the sealing performance between the water pipe 8 and the faucet assembly 9. The second anti-slip element 11 is disposed between the water pipe 8 and the faucet assembly 9 to prevent friction or shaking during assembly of the water pipe 8 and the faucet assembly 9. The anti-wear ring 12 is disposed on the outer surface of the water inlet end 802 of the water pipe 8 to improve the assembly feel when assembling the water pipe 8 and the faucet assembly 9.

[0073] In one embodiment, the faucet assembly 9 further includes a handle assembly 903 and a valve core 904, the valve core 904 being disposed between the hot and cold water inlet pipe 902 and the second opening 8002, and the handle assembly 903 being capable of driving the valve core 904 to open or close.

[0074] Specifically, such as Figure 3 As shown, the faucet assembly 9 of this application embodiment effectively ensures the quality of the cold and hot water delivered by the faucet by placing the valve core 904 between the hot and cold water inlet pipes 902 and the second opening 8002. Furthermore, this application also uses the handle assembly 903 to control the opening or closing of the valve core 904, effectively ensuring the water delivery effect of the faucet.

[0075] The handle assembly 903 has a first state, a second state and a third state. In the first state, the handle assembly 903 drives the valve core 904 to open, and the cold and hot water inlet pipe 902 delivers cold water to the flow passage 800. In the second state, the handle assembly 903 drives the valve core 904 to open, and the cold and hot water inlet pipe 902 delivers hot water to the flow passage 800. In the second state, the handle assembly 903 drives the valve core 904 to close, and the cold and hot water inlet pipe 902 stops delivering cold water or hot water to the flow passage 800.

[0076] In one embodiment, the faucet further comprises a bubbler 6 and a sealing connection shaft 7. The bubbler 6 is arranged at the water outlet end 801 of the water pipe 8. The bubbler 6 comprises a first outlet 601 and a second outlet 602. The first outlet 601 is in communication with the water outlet 101 of the purified water pipe 1 through the switch assembly 2, and the second outlet 602 is in communication with the first opening 8001 of the flow passage 800. One end of the sealing connection shaft 7 is connected with the top shaft 202, and the other end of the sealing connection shaft 7 is connected with the bubbler 6.

[0077] Specifically, as shown in Figure 1 and Figure 2 The bubbler 6 according to the embodiment of the application can be a double-water-path bubbler or a three-water-path bubbler.

[0078] For example, when the bubbler 6 is a double-water-path bubbler, the bubbler 6 comprises a first outlet 601 located at the center of the bubbler 6 and a second outlet 602 located at the periphery of the first outlet 601. The first outlet 601 is in communication with the water outlet 101 of the purified water pipe 1 through the switch assembly 2, and is used for outputting purified water. The second outlet 602 is in communication with the first opening 8001 of the flow passage 800, and is used for outputting cold water and hot water. When the bubbler 6 is a three-water-path bubbler, the bubbler 6 comprises a first outlet 601 located at the center of the bubbler 6 and a second outlet 602 located at the periphery of the first outlet 601. At this time, the second outlet comprises a first sub-outlet and a second sub-outlet. The first sub-outlet is arranged at the periphery of the first outlet 601, the second sub-outlet is arranged at the periphery of the first sub-outlet, and the first sub-outlet is located between the first outlet 601 and the second sub-outlet. Thus, the first outlet 601 is in communication with the water outlet 101 of the purified water pipe 1 through the switch assembly 2, and is used for outputting purified water. The first sub-outlet is in communication with the cold water supply water path of the flow passage 800, and is used for outputting cold water. The second sub-outlet is in communication with the hot water supply water path of the flow passage 800, and is used for outputting hot water.

[0079] Therefore, the water faucet can effectively improve the output effect of cold water, hot water and pure water through the setting of the bubbler 6.

[0080] In addition, the sealing connecting shaft 7 is used to connect the top shaft 202 and the bubbler 6, so that the sealing performance between the top shaft 202 and the bubbler 6 is effectively improved, the pure water pipe 1 is completely isolated from the flow channel 800, and the influence of the cold and hot water in the flow channel 800 on the water quality of the pure water is further avoided.

[0081] In addition, the sealing connecting shaft 7 is used to connect the top shaft 202 and the bubbler 6 in a bridging manner, so that the reliability of the connection between the top shaft 202 and the bubbler 6 is effectively improved, and the overall structure of the water faucet is simplified.

[0082] In one embodiment, the water faucet further comprises an anti-tripping device 5, the anti-tripping device 5 is arranged at the water outlet end 801, and the rotating shaft 203 further comprises a groove (not shown in the figure), which is in clamping connection with the anti-tripping device 5.

[0083] Specifically, as shown in Figure 1 and Figure 2 the water outlet end 801 of the water pipe 8 of the embodiment of the application is further provided with a groove (not shown in the figure) for accommodating the anti-tripping device 5, the groove has a groove depth greater than the thickness of the anti-tripping device 5, so that after the anti-tripping device 5 is installed in the groove, a certain gap is formed between the anti-tripping device 5 and the bottom wall of the groove.

[0084] Therefore, when the rotating shaft 203 is assembled, the anti-tripping device 5 can be pressed towards the bottom wall of the groove, so that the rotating shaft 203 is effectively prevented from falling off the water outlet end 801 of the water pipe 8.

[0085] In one embodiment, the water faucet further comprises an indicator lamp 15 and a sensor (not shown in the figure), the indicator lamp 15 is electrically connected with the sensor, and the sensor is arranged at the switch assembly 2; when the pure water passes through the switch assembly 2, the indicator lamp 15 is turned on.

[0086] Specifically, as shown in Figure 4 the indicator lamp 15 of the embodiment of the application is arranged at the faucet assembly 9, the sensor is arranged at the switch assembly 2, and the indicator lamp 15 is electrically connected with the sensor. The sensor can detect whether the pure water passes through the switch assembly 2.

[0087] For example, when the switch assembly 2 is opened, the purified water passes through the switch assembly 2, the indicator light 15 is turned on, and the faucet delivers the purified water; when the switch assembly 2 is closed, the purified water does not pass through the switch assembly 2, and the indicator light 15 is turned off.

[0088] Therefore, the use performance of the purified water device is effectively improved by the cooperation of the indicator light 15 and the sensor.

[0089] In addition, the switch assembly 2 is further provided with a filter element (not shown in the figure) for filtering the purified water passing through the switch assembly 2. The switch assembly 2 is further provided with a detection device (not shown in the figure) for detecting the filter element, which is used to detect the filtering performance of the filter element. The detection device can be electrically connected with the indicator light 15 to remind the user to replace the filter element when the filtering performance of the filter element does not meet the use requirement.

[0090] The indicator light 15 has a first state and a second state. In the first state, the switch assembly 2 is opened, the purified water passes through the switch assembly 2, and the indicator light 15 is turned on in blue. In the second state, the detection device detects that the filtering performance of the filter element does not meet the use requirement, and the indicator light 15 is turned on in red.

[0091] Of course, the indicator light 15 can also have other reminding modes. For example, in the first state, the indicator light 15 is turned on (here, the color displayed by the indicator light 15 is not limited, and the indicator light 15 can be turned on in blue, red, or yellow, etc.). In the second state, the indicator light 15 flashes, and those skilled in the art can select according to actual needs, which is not specifically limited herein.

[0092] In the above embodiments, the focus is on the differences between the various embodiments, and the different optimization features between the various embodiments can be combined to form a more optimal embodiment as long as they are not contradictory. Considering the brevity of the writing, it will not be repeated here.
