Description

Technical Field

[0001] The present application relates to the technical field of faucets, and particularly to a faucet. Background Art

[0002] Faucets are common household utensils used to control the on-off of water flow. Faucets are installed in the washing sinks, bathtubs, washstands, etc. in the family kitchen, and some drinking water equipment such as water dispensers, tea bar machines, and water purifiers also have faucets. Taking the water purifier as an example, with the improvement of people's living standards, water purifiers are widely used. Due to different drinking habits, some users like to drink normal temperature water, while some users like to drink hot water. Therefore, the integrated normal temperature and hot water purifier that can prepare normal temperature water and hot water has emerged, and the faucet that matches the integrated normal temperature and hot water purifier has also come into the public view.

[0003] At present, most of the faucets that match the integrated hot and cold water purifier commonly seen include a faucet housing and a water outlet nozzle disposed inside the faucet housing. The faucet drains water outward through the water outlet nozzle. Specifically, a hot water outlet cavity and a cold water outlet cavity are provided inside the water outlet nozzle. Hot water is discharged through the hot water outlet cavity, and normal temperature water is discharged through the cold water outlet cavity, solving the problem that the normal temperature water and hot water in the traditional water outlet nozzle are discharged through the same cavity, resulting in the mixing of normal temperature water and hot water, causing the temperature of the normal temperature water to be too high or the temperature of the cold water to be too low. The problem with this type of faucet currently is that: since a large amount of steam is generated during the discharge of hot water, when the hot water and steam are discharged together, the steam is likely to affect the water type of the hot water, causing the water column to float and tilt, increasing the risk of hot water splashing. To improve the above problems, most current water outlet nozzles are provided with exhaust ports to enable the steam to be discharged through a separate exhaust port, promoting the separation of water and vapor. There are various forms of the setting positions of the exhaust ports, but mainly include the following three: 1. The upper exhaust form, specifically setting the exhaust port at the top of the water outlet nozzle. This form is not very applicable to faucets with a display screen at the top. It is difficult to open a passage to avoid the exhaust port at the position where the display screen is set on the top of the faucet. Moreover, the mist generated by the upward discharge of steam is not conducive to the touch of the display screen; 2. The lower exhaust form, specifically setting the exhaust port at the bottom of the water outlet nozzle. In this form, the cold water outlet, the hot water outlet, and the exhaust port are arranged together on the bottom wall of the water outlet nozzle, resulting in all three ports being reduced in size, which is not conducive to large-flow drainage, increasing the water receiving time and poor experience, and the water flow is likely to enter the exhaust port during drainage; 3. The rear exhaust form, specifically setting it at the rear of the water outlet nozzle and connecting to an exhaust pipe extending towards the rear end of the faucet housing. This form has a long steam discharge path and a complex structure. The mist formed behind the faucet is likely to wet the wall, causing the wall to mildew. Moreover, further speaking, for the above three exhaust forms, exhaust ports need to be opened on the water outlet nozzle. In addition to the necessary cold water outlet and hot water outlet, the additional exhaust port increases the structural complexity of the water outlet nozzle and the manufacturing and processing costs become higher. Therefore, how to improve the defects existing in the faucet exhaust method is a technical problem to be solved in the faucet technology field. Utility Model Content

[0004] This application provides a faucet. The steam enters the cold water outlet channel through the steam channel for discharge, so as to solve the technical problems of the defects existing in the forms such as upper exhaust, lower exhaust, and rear exhaust of the current faucet and the increase in structural complexity caused by opening the exhaust port.

[0005] The technical solution adopted by this application is as follows:

[0006] A faucet, comprising a water outlet nozzle and a flow dividing device fitted below the water outlet nozzle. The water outlet nozzle is provided with a hot water outlet cavity and a cold water outlet cavity. The flow dividing device is provided with a hot water outlet channel and a cold water outlet channel surrounding the hot water outlet channel. The hot water outlet cavity communicates with the hot water outlet channel, and the cold water outlet cavity communicates with the cold water outlet channel. The water outlet nozzle and the flow dividing device cooperate to enclose a steam channel, and the steam channel communicates with the hot water outlet channel and the cold water outlet channel, so that when hot water is discharged from the hot water outlet channel, steam can be discharged through the steam channel and the cold water outlet channel.

[0007] The faucet provided by the present application further includes the following additional technical features:

[0008] The flow dividing device includes a water outlet shaft extending in the vertical direction. The hot water outlet channel is formed inside the water outlet shaft, and the cold water outlet channel is formed outside the water outlet shaft. A gap is provided between the top of the water outlet shaft and the bottom wall of the water outlet nozzle to enclose the steam channel.

[0009] A guide pipe communicating with the hot water outlet cavity is provided at the bottom of the water outlet nozzle. The guide pipe is inserted into the water outlet shaft from top to bottom, and the gap between the guide pipe and the water outlet shaft communicates the hot water outlet channel with the steam channel.

[0010] The hot water outlet channel includes a cylindrical section and a conical section from top to bottom. The inner diameter of the conical section gradually decreases from top to bottom, and the guide pipe is inserted into the cylindrical section.

[0011] A guide portion is provided at the bottom of the guide pipe. The gap between the guide portion and the inner wall of the water outlet shaft gradually increases from top to bottom.

[0012] Steam guide ribs are provided at the bottom of the water outlet nozzle. The steam guide ribs surround the water outlet shaft, and the gap between the steam guide ribs and the water outlet shaft communicates the steam channel with the cold water outlet channel.

[0013] A hot water flow retarder is provided in the hot water outlet channel. The installation position of the hot water flow retarder is lower than the steam channel, and the hot water flow retarder is a mesh structure with water passing mesh holes.

[0014] The flow dividing device includes a housing and an embedded bracket. The housing is vertically through, and the embedded bracket is embedded in the housing. The hot water outlet channel is provided in the embedded bracket, and the cold water outlet channel is formed between the embedded bracket and the housing.

[0015] A cold water flow retarder is provided in the cold water outlet channel. The installation position of the cold water flow retarder is lower than the steam channel, and the cold water flow retarder is a mesh structure with water passing mesh holes.

[0016] The faucet further includes a faucet housing and a decorative ring. The faucet housing is provided with a water outlet port. The water outlet nozzle is fixed inside the faucet housing. The decorative ring is threadedly connected to the faucet housing and, together with the water outlet nozzle, clamps the flow dividing device up and down within the water outlet port.

[0017] Due to the adoption of the above technical solutions, the technical effects achieved by this application at least include:

[0018] 1. In the faucet provided by this application, the water outlet nozzle is provided with a hot water outlet chamber and a cold water outlet chamber, so that hot water can be discharged through the hot water outlet chamber and normal temperature water can be discharged through the cold water outlet chamber, realizing the separate chamber and separate flow discharge of normal temperature water and hot water, and solving the problem of mixed water of normal temperature water and hot water. On this basis, a flow dividing device is correspondingly arranged below the water outlet nozzle. The flow dividing device is provided with a hot water outlet channel and a cold water outlet channel surrounding the hot water outlet channel. The hot water outlet channel is arranged in the middle, and the cold water outlet channel is arranged in a surrounding manner, forming a water outlet form in which hot water comes out from the center of the flow dividing device and normal temperature water comes out from the outer ring. For hot water with generally small water outlet flow rate, the gathering and guiding effect of the central arrangement of the hot water outlet channel makes the hot water come out in a beam shape, which helps to prevent the hot water from drifting obliquely, optimize the water type, and reduce the splashing phenomenon. For normal temperature water with generally large water outlet flow rate, the water comes out through the cold water outlet channel in the outer ring. The channel area is large, reducing the phenomenon of water outlet nozzle backpressure and increasing the outer diameter of the water outlet water column. More importantly, the water outlet nozzle and the flow dividing device cooperate to enclose a steam channel. The steam channel communicates with the hot water outlet channel and the cold water outlet channel, so that when the hot water outlet channel discharges hot water, the steam can be discharged through the steam channel and the cold water outlet channel, forming a downward exhaust form, solving the defects of the upward exhaust form that it is difficult to avoid the display screen and the fog affects the operation of the display screen, and solving the defects of the rear exhaust form that the exhaust path is long and the structure is complex. Moreover, there is no need to open an exhaust port on the bottom wall of the water outlet nozzle, making the structure of the water outlet nozzle simple, which is beneficial to expanding the areas of the cold water outlet and the hot water outlet, increasing the water discharge per unit time, and shortening the waiting time for receiving water. In addition, the temperature in the cold water outlet channel is much lower than that in the hot water outlet channel. After the steam enters the cold water outlet channel, it can form condensed water under the influence of low temperature, reducing the generation of fog. Moreover, most of the area below the faucet is a water receiving container, a washbasin or a pool. Therefore, the condensed water dripping into the water receiving container, the washbasin or the pool basically has no adverse effect.

[0019] 2. As a preferred embodiment of the present application, the hot water outlet channel is formed inside the outlet shaft, and the cold water outlet channel is formed outside the outlet shaft. There is a gap between the top of the outlet shaft and the bottom wall of the outlet nozzle to enclose a steam channel, so that the steam channel connects the top of the hot water outlet channel with the cold water outlet channel. When the hot water flows downward through the hot water outlet channel, the steam flows to the cold water outlet channel at a higher position, enabling the water vapor to be separated as much as possible. It also helps to extend the discharge path of the steam in the cold water outlet channel. On the one hand, it facilitates the condensation of more steam. On the other hand, at the initial stage of the faucet discharging hot water, since the steam needs to pass through the steam channel and the cold water outlet channel and is not discharged from the faucet, it reserves the user's reaction time and avoids scalding by effective steam.

[0020] 3. As a preferred embodiment of the present application, the guide pipe is inserted into the outlet shaft from top to bottom. The gap between the guide pipe and the outlet shaft connects the hot water outlet channel with the steam channel. On the one hand, the guide pipe can pre-converge the hot water in the hot water outlet cavity into a bundle and then stably guide it into the outlet shaft. On the other hand, when the hot water flows downward, the steam needs to flow upward through the gap between the guide pipe and the outlet shaft to reach the steam channel, promoting the reverse flow separation of water vapor and extending the steam discharge path. Moreover, on the basis of allowing the steam to pass through, the gap between the guide pipe and the outlet shaft effectively prevents the hot water from flowing into the steam channel, thereby reducing the risk of the hot water blocking the steam channel and the hot water discharging from the cold water outlet channel.

[0021] 4. As a preferred embodiment of the present application, the steam guide ribs surround the outlet shaft. The gap between the steam guide ribs and the outlet shaft connects the steam channel with the cold water outlet channel. The steam guide ribs guide the steam to discharge downward, effectively preventing the cold water outlet channel from being blocked by air and ensuring smooth steam discharge.

[0022] 5. As a preferred embodiment of the present application, a hot water flow retarder is installed in the hot water outlet channel. The hot water flow retarder is a mesh structure with water passing mesh holes. On the one hand, it makes the hot water flow passing through the hot water flow retarder have a foaming effect, and the generated bubbles enhance the scouring force of the water when they burst. On the other hand, under the resistance of the hot water flow retarder, the softness of the water outlet is improved, the water outlet pattern is improved, and it also helps with the separation of water vapor, enabling more steam to condense or be discharged through the steam channel and the cold water outlet channel.

[0023] 6. As a preferred embodiment of the present application, the hot water outlet channel includes a cylindrical section and a conical section. The diversion pipe is inserted into the cylindrical section. The inner diameter of the cylindrical section remains the same from top to bottom, which is convenient for the insertion of the diversion pipe. Moreover, after the diversion pipe is inserted into the cylindrical section, it can ensure that there is a sufficiently large gap between the diversion pipe and the water outlet axis to connect the hot water outlet channel and the steam channel, facilitating the upward flow of steam. The inner diameter of the conical section gradually decreases from top to bottom. On the one hand, at the lower position of the conical section, the smaller the water outlet area, which helps to gather the hot water into a bundle, making the hot water column straighter and not skewed. On the other hand, as the area of the conical section decreases from top to bottom, the hot water is more abundant, leaving less flow space for the steam, which helps to promote the separation of water and vapor, enabling more steam to flow into the steam channel.

[0024] 7. As a preferred embodiment of the present application, a hot water flow retarder is provided in the hot water outlet channel. The installation position of the hot water flow retarder is lower than that of the steam channel. The hot water flow retarder is a net-like structure with water passing mesh holes. On the one hand, it makes the hot water flow passing through the hot water flow retarder have a foaming effect, and the bubbles generated enhance the scouring force of the water when they burst. On the other hand, under the resistance of the hot water flow retarder, the softness of the water outlet is improved, the water outlet pattern is improved, and it also helps to separate water and vapor, enabling more steam to condense or be discharged through the steam channel and the cold water outlet channel.

For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0048] In the description of this specification, the description with reference to terms such as "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of this application. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0049] In the embodiments of this application, a faucet is provided. For the convenience of description and understanding, the following content provided in this application is all elaborated on the basis of the illustrated product structure. Of course, those skilled in the art can understand that the above structure is only a specific example and schematic description, and does not constitute a specific limitation on the technical solution provided in this application.

[0050] As Figures 1 to 10 shown, a faucet provided in this application includes a water outlet nozzle 1 and a flow dividing device 2 fitted below the water outlet nozzle 1. The water outlet nozzle 1 is provided with a hot water outlet cavity 11 and a cold water outlet cavity 12. The flow dividing device 2 is provided with a hot water outlet channel 21 and a cold water outlet channel 22 surrounding the hot water outlet channel 21. The hot water outlet cavity 11 communicates with the hot water outlet channel 21, and the cold water outlet cavity 12 communicates with the cold water outlet channel 22. The water outlet nozzle 1 and the flow dividing device 2 cooperate to enclose a steam channel 3. The steam channel 3 communicates with the hot water outlet channel 21 and the cold water outlet channel 22, so that when hot water is discharged through the hot water outlet channel 21, steam can be discharged through the steam channel 3 and the cold water outlet channel 22.

[0051] For the faucet of this application, the water outlet nozzle 1 is provided with a hot water outlet cavity 11 and a cold water outlet cavity 12, so that hot water can be discharged through the hot water outlet cavity 11, and normal temperature water is discharged through the cold water outlet cavity 12, realizing the separate cavity and separate flow discharge of normal temperature water and hot water, and solving the problem of mixed water formed by the discharge of normal temperature water and hot water in the same cavity. Specifically, as Figure 5As shown in the figure, a partition wall 13 can be arranged inside the water outlet nozzle 1. The inner cavity of the water outlet nozzle 1 is separated into a hot water outlet cavity 11 and a cold water outlet cavity 12 by the partition wall 13. The water outlet nozzle 1 is provided with a hot water inlet 14 corresponding to the hot water outlet cavity 11 and a normal temperature water inlet 15 corresponding to the cold water outlet cavity 12.

[0052] On the basis of the separate discharge of normal temperature water and hot water, a flow splitting device 2 is correspondingly arranged below the water outlet nozzle 1. The flow splitting device 2 is provided with a hot water outlet channel 21 and a cold water outlet channel 22 surrounding the hot water outlet channel 21. The hot water outlet channel 21 is arranged in the middle, and the cold water outlet channel 22 is arranged in a surrounding manner, forming a water outlet form in which hot water is discharged from the center of the flow splitting device 2 and normal temperature water is discharged from the outer ring. For the hot water with a generally small water discharge flow, the converging and guiding effect of the central arrangement of the hot water outlet channel 21 makes the hot water discharge in a beam shape, which helps to prevent the hot water from drifting obliquely, optimize the water type, and reduce the splashing phenomenon. For the normal temperature water with a generally large water discharge flow, it is discharged through the cold water outlet channel 22 on the outer ring. The channel area is large, which reduces the phenomenon of the water outlet nozzle 1 being blocked by normal temperature water pressure and can increase the outer diameter of the water column discharged.

[0053] More importantly, the water outlet nozzle 1 and the flow splitting device 2 cooperate to enclose a steam channel 3. The steam channel 3 communicates with the hot water outlet channel 21 and the cold water outlet channel 22, so that when the hot water outlet channel 21 discharges hot water, steam can be discharged through the steam channel 3 and the cold water outlet channel 22, forming a downward exhaust form, solving the defects of the upward exhaust form that it is difficult to avoid the display screen and the fog affects the operation of the display screen, and solving the defects of the rear exhaust form that the exhaust path is long and the structure is complex. Moreover, there is no need to open an exhaust port on the bottom wall of the water outlet nozzle 1, making the structure of the water outlet nozzle 1 simple, which is beneficial to expanding the areas of the cold water outlet and the hot water outlet, increasing the water discharge volume per unit time, and shortening the waiting time for receiving water. In addition, the temperature in the cold water outlet channel 22 is much lower than that in the hot water outlet channel 21. After the steam enters the cold water outlet channel 22, it can form condensed water under the influence of low temperature, reducing the generation of fog. And most of the areas below the faucet are directly opposite to the water receiving container, washbasin or pool. Therefore, the condensed water dripping into the water receiving container, washbasin or pool basically has no adverse effects.

[0054] As a preferred embodiment of the present application, as Figure 3 、 Figure 4 、 Figure 6 and Figure 7As shown, the flow dividing device 2 includes a water outlet shaft 241 extending in the vertical direction. The hot water outlet channel 21 is formed within the water outlet shaft 241, and the cold water outlet channel 22 is formed outside the water outlet shaft 241. A gap is provided between the top of the water outlet shaft 241 and the bottom wall of the water outlet nozzle 1 to form the steam channel 3. Those skilled in the art can understand that in order to facilitate the effective separation of steam during the hot water discharge process, the steam channel 3 should be as far away as possible from the bottom outlet of the hot water outlet channel 21 to reduce the amount of steam carried by the hot water when it is discharged from the bottom outlet. Therefore, by providing a gap between the top of the water outlet shaft 241 and the bottom wall of the water outlet nozzle 1 to form the steam channel 3, the steam channel 3 connects the top of the hot water outlet channel 21 with the cold water outlet channel 22. During the downward flow of hot water through the hot water outlet channel 21, steam flows towards the cold water outlet channel 22 at a higher position, enabling the separation of water vapor as much as possible. It also helps to extend the discharge path of steam within the cold water outlet channel 22. On the one hand, it is convenient for more steam to condense. On the other hand, at the initial stage of the faucet discharging hot water, since steam needs to pass through the steam channel 3 and the cold water outlet channel 22 and is not discharged from the faucet, it reserves the user's reaction time and avoids scalding by effective steam.

[0055] As a preferred embodiment of this embodiment, as Figure 3 、 Figure 4 and Figure 6 shown, a diversion pipe 16 communicating with the hot water outlet cavity 11 is provided at the bottom of the water outlet nozzle 1. The diversion pipe 16 is inserted into the water outlet shaft 241 from top to bottom. The gap between the diversion pipe 16 and the water outlet shaft 241 connects the hot water outlet channel 21 with the steam channel 3. The diversion pipe 16 connects the hot water outlet cavity 11 and the hot water outlet channel 21. The diversion pipe 16 is inserted into the water outlet shaft 241 from top to bottom, and the gap between the diversion pipe 16 and the water outlet shaft 241 connects the hot water outlet channel 21 with the steam channel 3. On the one hand, the diversion pipe 16 can pre-converge the hot water in the hot water outlet cavity 11 into a bundle and then stably guide it into the water outlet shaft 241. On the other hand, when the hot water flows downward, steam needs to flow upward through the gap between the diversion pipe 16 and the water outlet shaft 241 to reach the steam channel 3, promoting the reverse flow separation of hot water and steam and extending the steam discharge path. Moreover, on the basis of allowing steam to pass through, the gap between the diversion pipe 16 and the water outlet shaft 241 effectively prevents hot water from flowing into the steam channel 3, thereby reducing the risk of hot water blocking the steam channel 3 and hot water being discharged from the cold water outlet channel 22.

[0056] Furthermore, in this embodiment, as Figure 3 and Figure 8As shown, the hot water outlet channel 21 includes a cylindrical section 211 and a conical section 212 from top to bottom. The inner diameter of the conical section 212 gradually decreases from top to bottom, and the diversion pipe 16 is inserted into the cylindrical section 211. Specifically, the inner diameter of the cylindrical section 211 of the hot water outlet channel 21 remains the same from top to bottom, which is convenient for the insertion of the diversion pipe 16. Moreover, after the diversion pipe 16 is inserted into the cylindrical section 211, it can also ensure that there is a sufficiently large gap between the diversion pipe 16 and the water outlet shaft 241 to connect the hot water outlet channel 21 with the steam channel 3, facilitating the upward flow of steam. The inner diameter of the conical section 212 of the hot water outlet channel 21 gradually decreases from top to bottom. On the one hand, at the lower position of the conical section 212, the smaller the water outlet area, which helps to gather the hot water into a bundle, making the hot water column straighter and not skewed. On the other hand, as the area of the conical section 212 decreases from top to bottom, the hot water is more filled, leaving less flow space for the steam, which helps to promote the separation of water and steam, enabling more steam to flow into the steam channel 3.

[0057] Furthermore, in this embodiment, as Figure 4 shown, a diversion portion 161 is provided at the bottom of the diversion pipe 16, and the gap between the diversion portion 161 and the inner wall of the water outlet shaft 241 gradually increases from top to bottom. Specifically, regarding the structure of the diversion portion 161, it can be set as a chamfer formed by cutting at the bottom edge of the diversion pipe 16, and the gap between the position where the chamfer is located and the inner wall of the water outlet shaft 241 is enlarged, facilitating the upward flow of the steam in the hot water outlet channel 21 into the gap between the diversion pipe 16 and the water outlet shaft 241.

[0058] As a preferred embodiment of this implementation manner, as Figure 3 、 Figure 4 and Figure 6 shown, steam diversion ribs 17 are provided at the bottom of the water outlet nozzle 1. The steam diversion ribs 17 surround the water outlet shaft 241, and the gap between the steam diversion ribs 17 and the water outlet shaft 241 connects the steam channel 3 with the cold water outlet channel 22. Through this design, when the steam is discharged from the steam channel 3 towards the cold water outlet channel 22, the steam diversion ribs 17 guide the steam to be discharged downward, effectively avoiding the phenomenon of air blockage in the cold water outlet channel 22 and ensuring smooth steam discharge.

[0059] As a preferred implementation manner of this application, as Figures 2 to 4As shown, a hot water slow flow member 4 is provided in the hot water outlet channel 21. The installation position of the hot water slow flow member 4 is lower than that of the steam channel 3. The hot water slow flow member 4 is a net-like structure with water passing mesh holes. On the one hand, it makes the hot water flow passing through the hot water slow flow member 4 have a foaming effect, and the generated bubbles enhance the scouring force of the water when they burst. On the other hand, under the resistance of the hot water slow flow member 4, the softness of the water outlet is improved, the water outlet water pattern is improved, and it also helps with water-vapor separation, enabling more steam to be condensed or discharged through the steam channel 3 and the cold water outlet channel 22. Further, a support portion for supporting the hot water slow flow member 4 can be provided on the inner wall of the water outlet shaft 241. The support portion can be designed as a step formed on the inner wall of the water outlet shaft 241 to stably support the hot water slow flow member 4 through the step.

[0060] Regarding the specific structure of the flow splitting device 2, as a preferred embodiment of the present application, as Figure 2 shown Figure 9 in, the flow splitting device 2 includes a housing 23 and an embedded bracket 24. The housing 23 penetrates up and down. The embedded bracket 24 is embedded in the housing 23. The hot water outlet channel 21 is provided in the embedded bracket 24. A cold water outlet channel 22 is formed between the embedded bracket 24 and the housing 23. Since the hot water outlet channel 21 is provided in the embedded bracket 24, in the technical solution where the flow splitting device 2 includes a water outlet shaft 241 extending in the vertical direction and the hot water outlet channel 21 is formed in the water outlet shaft 241, the water outlet shaft 241 can be formed in the center of the embedded bracket 24, and a cold water outlet channel 22 is formed between the outer wall of the water outlet shaft 241 and the housing 23. Compared with designing the flow splitting device 2 as an integral structure, designing it as a split structure composed of the housing 23 and the embedded bracket 24 facilitates the respective processing and forming, reduces the demolding difficulty, and also facilitates the installation of other components beneficial to improving the water outlet water pattern and helping with water-vapor separation in the housing 23 or the embedded bracket 24 and then assembling the housing 23 and the embedded bracket 24 together. As Figure 3 shown Figure 7 in, Figure 8 it can be made such that the embedded bracket 24 further includes a positioning portion 242 extending outward in the circumferential direction of the water outlet shaft 241. The housing 23 supports the positioning portion 242 upward and radially limits the positioning portion 242 to ensure the relative fixation of the housing 23 and the embedded bracket 24 in the vertical direction and the radial direction.

[0061] Further, as Figure 2 shown Figure 3As shown, a cold water slow flow member 5 is provided in the cold water outlet channel 22. The installation position of the cold water slow flow member 5 is lower than that of the steam channel 3. The cold water slow flow member 5 is a mesh structure with water passing mesh holes. On the one hand, it makes the normal temperature water flow passing through the cold water slow flow member 5 have a foaming effect, and the generated bubbles enhance the scouring force of the water when they burst. On the other hand, when the steam passes through the cold water slow flow member 5, it contacts the cold water slow flow member 5 over a large area, and the low temperature of the cold water slow flow member 5 can be used to promote the condensation of the steam.

[0062] As a preferred embodiment of the present application, as Figure 1 , Figure 2 and Figure 10 shown, the faucet further includes a faucet housing 6 and a decorative ring 7. The faucet housing 6 is provided with a water outlet port 61. The water outlet nozzle 1 is fixed inside the faucet housing 6. The decorative ring 7 is threadedly connected to the faucet housing 6 and, together with the water outlet nozzle 1, clamps the flow dividing device 2 up and down inside the water outlet port 61. In a preferred embodiment, the water outlet nozzle 1 can be fixed inside the faucet housing 6 by screws. After the water outlet nozzle 1 is fixed in place inside the faucet housing 6, the assembled flow dividing device 2 is installed below the water outlet nozzle 1. Finally, the decorative ring 7 is threadedly connected to the faucet housing 6, so that the flow dividing device 2 is clamped up and down between the water outlet nozzle 1 and the decorative ring 7. In a preferred embodiment, as Figure 10 shown, the bottom of the decorative ring 7 can be turned inward to form a limiting flange 71, and the limiting flange 71 abuts against the bottom of the housing 23 of the flow dividing device 2, so as to clamp the flow dividing device 2 at the bottom of the flow dividing device 2. In another preferred embodiment, as Figure 3 , Figure 6 and Figure 10 shown, a limiting ring rib 18 extending downward can be provided at the bottom of the water outlet nozzle 1. The flow dividing device 2 is embedded in the limiting ring rib 18 and is in radial contact with the limiting ring rib 18, so as to limit the radial movement of the flow dividing device 2 through the limiting ring rib 18.
