Description

Technical Field

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

[0002] Faucets are common household utensils used to control the on-off of water flow. They are installed in the washing sinks, bathtubs, washbasins, etc. in the family kitchen, and some drinking water equipment such as water dispensers, tea bar machines, and water purifiers also have faucets. Taking a water purifier as an example, with the improvement of people's living standards, water purifiers are widely used, and the faucets matching water purifiers have also come into the public view.

[0003] At present, most of the relatively common faucets of water purifiers mostly include a faucet main body and a pure water elbow pipe respectively connected to the faucet main body. The pure water elbow pipe is used to discharge pure water. During the filtration process of the water purifier, wastewater will be generated, especially for RO water purifiers, which will generate a large amount of wastewater during the filtration process and the flushing process of the RO membrane. Most of these wastewaters are discharged into the sewer through the wastewater outlet of the machine body by the wastewater pipe. The wastewater is directly discharged and cannot be reused, resulting in a waste of water resources. At the same time, the wastewater pipe needs to be firmly fixed inside the inlet of the sewer pipe. However, the conventional operation of the water purifier installer is to directly insert the wastewater pipe into the sewer pipe, which makes the wastewater pipe easily pop out to the ground from the inlet of the sewer pipe due to reasons such as pressure buildup and accidental touch. If not noticed, it will cause the wastewater to be discharged onto the ground.

[0004] To solve the above problems, a simple method is to insert the wastewater pipe into a water storage container for collection and utilization, but it is easy to cause the water in the water storage container to overflow, resulting in a poor experience. In addition, a new type of faucet capable of recycling wastewater has emerged on the market. The wastewater of the water purifier is no longer directly discharged into the sewer through the wastewater pipe, but is discharged through the faucet. Specifically, in addition to connecting a pure water elbow pipe to the faucet main body, such a faucet is also connected with a wastewater elbow pipe for discharging wastewater. During the filtration process of the water purifier, after the wastewater switch is turned on, the wastewater elbow pipe discharges wastewater at a fixed flow rate. However, for RO water purifiers, they usually need to be equipped with a function of adjustable wastewater ratio to meet the corresponding filtration requirements and RO membrane flushing requirements. Otherwise, it will affect the normal use, and seriously, it will also affect the optimal flushing frequency, cause fouling of the wastewater ratio, and reduce the service life of the RO membrane. It can be seen that the current faucets with wastewater elbow pipes obviously cannot meet the wastewater discharge requirements of RO water purifiers. Summary of the Utility Model

[0018] Due to the adoption of the above technical solution, the technical effects achieved by this application at least include:

[0019] 1. The faucet provided by the present application is provided with a pure water discharge port and a wastewater discharge port on the faucet body, which can realize the discharge of pure water and wastewater, and is applicable to various common water purifiers on the market, especially suitable for RO water purifiers. During the process of water production or RO membrane flushing, a large amount of wastewater produced can be discharged through the wastewater discharge port of the faucet body. Moreover, most of the space below the faucet is directly opposite to a water receiving container, a washbasin or a sink. Therefore, the wastewater can be discharged into the water receiving container, the washbasin or the sink for domestic water use, realizing secondary utilization, greatly reducing water resource waste, and also solving the problem that when the wastewater is discharged through the wastewater pipe, the wastewater pipe pops out from the inlet of the sewer pipe to the ground, causing water leakage to the ground. Furthermore, the discharge of pure water from the pure water discharge port and the discharge of wastewater from the wastewater discharge port can be carried out simultaneously without interference with each other, ensuring the normal use of the water purifier. More importantly, a wastewater regulating valve is provided in the wastewater discharge channel. The wastewater regulating valve can be driven by a flow regulating member to adjust the water flow rate of the wastewater discharge channel, so that the wastewater regulating valve can be switched between a state of cutting off the wastewater discharge channel and a state of conducting the wastewater discharge channel, and can also adjust the magnitude of the water flow rate, solving the defect of the faucet discharging wastewater at a fixed flow rate, meeting the wastewater discharge requirements of the RO water purifier, further meeting the requirements of different wastewater ratios for the filtration and RO membrane flushing of the RO water purifier, and prolonging the service life of the RO membrane.

[0020] 2. As a preferred embodiment of the present application, the wastewater regulating valve includes a valve core and a valve body sleeved on the valve core. An adjusting channel is formed between the valve core and the valve body. The flow regulating member drives the valve core to move in the valve body to change the size of the opening of the adjusting channel. The larger the opening of the adjusting channel, the greater the amount of water passing through the adjusting channel per unit time, and the greater the wastewater water flow rate. The smaller the opening of the adjusting channel, the smaller the amount of water passing through the adjusting channel per unit time, and the smaller the wastewater water flow rate. Moreover, there are a large number of ways to drive the valve core to move relative to the valve body, which helps to select a method with low cost, reliable use and simple operation to drive the valve core to move.

[0021] 3. As a preferred embodiment of the present application, the flow regulating member moves along a first direction, and the adjusting portion gradually abuts against the wastewater regulating valve from the first end to the second end. Since the adjusting portion is configured to have a structure that gradually thickens from the first end to the second end, during the process that the adjusting portion gradually abuts against the wastewater regulating valve from the first end to the second end, the moving stroke of the wastewater regulating valve gradually increases, and the water flow rate in the wastewater discharge channel gradually increases. When the flow regulating member moves along a second direction, the adjusting portion gradually abuts against the wastewater regulating valve from the second end to the first end, the moving stroke of the wastewater regulating valve gradually shrinks until it resets to the initial state, and the water flow rate in the wastewater discharge channel gradually decreases until the wastewater discharge channel is cut off by the wastewater regulating valve. The moving mode of the flow regulating member has a large selectivity, and a convenient and ergonomic way can be selected according to the user's operation habit to improve the use experience.

[0022] 4. As a preferred embodiment of the present application, the housing includes a mounting portion, a water inlet portion, and a water outlet portion. The water inlet portion extends downward for easy connection to the wastewater pipe of the water purifier, and the water outlet portion extends upward to facilitate setting the wastewater discharge port at a higher position of the faucet body for convenient wastewater discharge. The flow regulating member is disposed in the mounting portion and can drive the wastewater regulating valve to move up and down in the water inlet portion or in the water outlet portion to adjust the water flow rate, further enhancing the simplicity of operation and adjustment.

[0023] 5. As a preferred embodiment of the present application, one end of the flow regulating member is located outside the faucet housing, enabling direct operation of the flow regulating member outside the faucet housing. The other end of the flow regulating member passes through the mounting hole and enters the wastewater discharge channel to contact the wastewater regulating valve. The flow regulating member can rotate in the mounting hole and drive the wastewater regulating valve to act during rotation. Moreover, by restricting the flow regulating member within the rotational degree of freedom, rotating the flow regulating member in one direction can cause the wastewater regulating valve to act in the direction of increasing water flow rate, while rotating in the opposite direction can cause the wastewater regulating valve to act in the direction of decreasing water flow rate. The operation is simple, the movement range of the flow regulating member is small, and the structure of the faucet body is more compact.

[0024] 6. As a preferred embodiment of the present application, the first positioning member abuts against the outer wall of the faucet housing to limit the mounting portion. The first positioning member is further provided with a stop wall that abuts against the flow regulating member to restrict the axial movement of the flow regulating member. Therefore, the first positioning member not only limits the mounting portion and confines the mounting portion in the first avoidance hole to prevent it from retracting into the faucet housing, but also ensures the stability of the flow regulating member in the mounting hole by restricting the axial movement of the flow regulating member, thereby guaranteeing the effectiveness of the water flow rate adjustment.

[0052] For a clearer explanation of the overall concept of this application, the following will be described in detail by way of examples in conjunction with the accompanying drawings of the specification.

[0053] In the following description, many specific details are set forth in order to provide a thorough understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited by the specific embodiments disclosed below.

[0054] In addition, in the description of this application, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", "lateral", "longitudinal", etc. are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to this application.

[0055] In this application, unless otherwise clearly defined and limited, the terms "installed", "connected", "connected to", "fixed", etc. shall be understood in a broad sense.

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.

[0056] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples", etc. 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 descriptions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0057] In the embodiments of the present application, a water faucet capable of discharging wastewater is provided. For the convenience of description and understanding, the following content provided in the present application is elaborated based on 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 the present application.

[0058] As Figures 1 to 13 shown, a water faucet capable of discharging wastewater provided in the present application includes a faucet main body 300. A pure water discharge port and a wastewater discharge port 81 are provided on the faucet main body 300. The faucet main body 300 includes a faucet housing 1 and a wastewater discharge assembly. The wastewater discharge assembly includes a housing 2, a wastewater regulating valve 3, and a flow regulating member 4. The housing 2 is disposed inside the faucet housing 1 and is provided with a wastewater discharge channel 21. The outlet end of the wastewater discharge channel 21 is communicated with the wastewater discharge port 81. The wastewater regulating valve 3 is disposed inside the wastewater discharge channel 21. The flow regulating member 4 is used to drive the wastewater regulating valve 3 to act to regulate the water flow rate of the wastewater discharge channel 21.

[0059] For the water faucet of the present application, a pure water discharge port and a wastewater discharge port 81 are provided on the faucet main body 300, which can realize pure water discharge and wastewater discharge, and is applicable to various common water purifiers on the market, especially RO water purifiers. During the process of water production or RO membrane flushing of the RO water purifier, a large amount of wastewater produced can be discharged through the wastewater discharge port 81 of the faucet main body 300. Moreover, most of the water faucets are directly opposite to a water receiving container, a washbasin or a sink below. Therefore, the wastewater can be discharged into the water receiving container, the washbasin or the sink for domestic water use, realizing secondary utilization, greatly reducing water resource waste, and also solving the problem that the wastewater pipe pops out from the inlet of the sewer pipe to the ground and causes water leakage to the ground when the wastewater is discharged through the wastewater pipe. Moreover, the pure water discharge port discharges pure water and the wastewater discharge port 81 discharges wastewater can be carried out simultaneously, without interfering with each other, ensuring the normal use of the water purifier. More importantly, a wastewater regulating valve 3 is provided inside the wastewater discharge channel 21, and the flow regulating member 4 can be used to drive the wastewater regulating valve 3 to act to regulate the water flow rate of the wastewater discharge channel 21, so that the wastewater regulating valve 3 can be switched between the state of cutting off the wastewater discharge channel 21 and the state of conducting the wastewater discharge channel 21, and the water flow rate can also be adjusted, solving the defect of fixed flow rate of the water faucet for discharging wastewater, meeting the wastewater discharge requirements of the RO water purifier, further meeting the requirements of different wastewater ratios for the filtration and RO membrane flushing of the RO water purifier, and prolonging the service life of the RO membrane. Moreover, when the RO water purifier is installed, the installer can adjust the wastewater flow rate according to the local water quality according to the given standard to make it adapt to the best state of RO membrane filtration and prolong the membrane life.

[0060] Specifically, as Figure 1 、 Figure 2 andFigure 4 As shown, for the convenience of pure water and wastewater discharge, the pure water discharge port can be set at the top of the faucet body 300 and connected to the pure water discharge elbow 5. The wastewater discharge port can also be set at the top of the faucet body 300. However, setting the wastewater discharge port at the top of the faucet body 300 will cause pressure on the top space of the faucet body 300. Therefore, preferably, the wastewater discharge port 81 can be set at the side of the faucet body 300 to achieve side discharge of wastewater, creating a height difference between pure water discharge and wastewater discharge to avoid mutual interference between the two. The inlet end of the wastewater discharge channel 21 can also be connected to a wastewater inlet pipe 6, so that the wastewater produced during the operation of the water purifier flows through the wastewater inlet pipe 6 to the wastewater discharge channel 21.

[0061] The present application does not limit the method of adjusting the water flow rate of the wastewater discharge channel 21 by the wastewater regulating valve 3. Flow regulating valves such as angle valves, needle valves, butterfly valves, diaphragm valves, etc. can be selected, or other suitable structures can also be selected. As a preferred embodiment, as Figure 4 、 Figure 5 and Figure 7 shown, the wastewater regulating valve 3 includes a valve core 31 and a valve body 32 sleeved on the valve core 31. The valve body 32 is relatively fixed to the housing 2. A regulating channel 33 that conducts the inlet end and the outlet end of the wastewater discharge channel 21 is formed by the cooperation between the valve core 31 and the valve body 32. The flow regulating member 4 drives the valve core 31 to move within the valve body 32 to change the size of the opening of the regulating channel 33, thereby achieving the adjustment of the water flow rate. Those skilled in the art can understand that an adjusting channel 33 is formed between the valve core 31 and the valve body 32. The larger the opening of the adjusting channel 33, the greater the amount of water passing through the adjusting channel 33 per unit time, and thus the greater the wastewater water flow rate. The smaller the opening of the adjusting channel 33, the smaller the amount of water passing through the adjusting channel 33 per unit time, and thus the smaller the wastewater water flow rate. Moreover, there are a large number of options for the method of driving the valve core 31 to move relative to the valve body 32, which helps to select a method with low cost, reliable use, and simple operation to drive the valve core 31 to move. In a preferred embodiment, as Figure 5 、 Figure 7 and Figure 11 shown, a limiting protrusion 321 can be provided on the outer wall of the valve body 32, and a limiting groove 22 can be provided on the inner wall of the wastewater discharge channel 21. The valve body 32 is relatively fixed to the housing 2 by the cooperation of the limiting protrusion 321 and the limiting groove 22. Sealing rings can be provided on the inner walls of the valve body 32 and the wastewater discharge channel 21 to ensure that wastewater does not pass through the gap between the inner walls of the valve body 32 and the wastewater discharge channel 21. Sealing rings can also be provided on the valve core 31, so that when the valve core 31 closes the opening of the regulating channel 33, the sealing ring abuts against the valve body 32 to ensure the sealing performance of the closing of the opening of the regulating channel 33.

[0062] Further, as shown in Figure 4 , Figure 5 and Figure 7 , one end of the valve core 31 is provided with a driving portion 311 extending outside the valve body 32. The flow rate adjusting member 4 drives the valve core 31 to move by pushing against the driving portion 311. The waste water regulating valve 3 further includes an elastic member 34 disposed between the valve core 31 and the valve body 32. The elastic member 34 is used to reset the valve core 31 to a position closing the regulating passage 33. The driving portion 311 extends out of the valve body 32, and the flow rate adjusting member 4 can directly act on the driving portion 311 outside the valve body 32 to drive the valve core 31 to move without going deep into the valve body 32, so the structure is simpler. The elastic member 34 is used to reset the valve core 31 to a position closing the regulating passage 33. Specifically, when the flow rate adjusting member 4 drives the valve core 31 to act in the direction of increasing the water flow rate, the elastic member 34 is stretched under the traction of the valve core 31. When the thrust acting on the valve core 31 by the flow rate adjusting member 4 gradually decreases until it disappears, the elastic member 34 restores its deformation and pulls the valve core 31 to reset until the opening of the regulating passage 33 is closed. Specifically, the elastic member 34 can be a spring, and the spring is sleeved on the valve core 31 and limited between the valve core 31 and the valve body 32.

[0063] The application also does not limit the manner in which the flow rate adjusting member 4 drives the waste water regulating valve 3 to act. Preferably, the flow rate adjusting member 4 can drive the waste water regulating valve 3 to act through activities such as translation and rotation. The activity mode of the flow rate adjusting member 4 has a large selectivity, and a convenient and ergonomic manner can be selected according to the user's operation habit to improve the use experience. As a preferred embodiment, as shown in Figure 3 , Figure 4 , Figure 8 and Figure 9 , the flow rate adjusting member 4 is provided with an adjusting portion 41 protruding from the outer wall. The adjusting portion 41 is configured to have a structure that gradually thickens from the first end to the second end; the flow rate adjusting member 4 moves in the first direction, and the adjusting portion 41 gradually abuts against the waste water regulating valve 3 from the first end to the second end, so that the waste water regulating valve 3 acts in the direction of increasing the water flow rate; the flow rate adjusting member 4 moves in the second direction, and the adjusting portion 41 gradually abuts against the waste water regulating valve 3 from the second end to the first end, so that the waste water regulating valve 3 acts in the direction of decreasing the water flow rate. Figure 8 and Figure 9FIG. 0 schematically shows an embodiment in which the adjusting portion 41 extends circumferentially along the flow rate adjusting member 4. Therefore, this solution is adapted to the solution in which the flow rate adjusting member 4 drives the waste water regulating valve 3 to act by rotation. In this embodiment, the flow rate adjusting member 4 rotates in the first direction, and the adjusting portion 41 gradually abuts against the waste water regulating valve 3 from the first end to the second end. Since the adjusting portion 41 is configured to have a structure that gradually thickens from the first end to the second end, during the process that the adjusting portion 41 gradually abuts against the waste water regulating valve 3 from the first end to the second end, the moving stroke of the waste water regulating valve 3 gradually increases, and the water flow rate in the waste water discharge channel 21 gradually increases. When the flow rate adjusting member 4 rotates in the second direction, the adjusting portion 41 gradually abuts against the waste water regulating valve 3 from the second end to the first end, and the moving stroke of the waste water regulating valve 3 gradually decreases until it returns to the initial state, and the water flow rate in the waste water discharge channel 21 gradually decreases until the waste water discharge channel 21 is blocked by the waste water regulating valve 3. Taking the solution in which the aforementioned waste water regulating valve 3 includes a valve core 31, a valve body 32, and the valve core 31 is provided with a driving portion 311 as an example, when the flow rate adjusting member 4 rotates in the first direction, the adjusting portion 41 gradually abuts against the driving portion 311 from the first end to the second end, driving the valve core 31 to move in the direction of increasing the opening of the adjusting channel 33, so that the water flow rate in the waste water discharge channel 21 increases. When the flow rate adjusting member 4 rotates in the second direction, the adjusting portion 41 gradually abuts against the driving portion 311 from the second end to the first end, and the valve core 31 moves in the direction of decreasing the opening of the adjusting channel 33 under the action of the elastic member 34, so that the water flow rate in the waste water discharge channel 21 gradually decreases. As an alternative embodiment, the adjusting portion 41 may also extend in a straight line direction to be adapted to the solution in which the flow rate adjusting member 4 drives the waste water regulating valve 3 to act by linear translation.

[0064] Regarding the structure of the housing 2, as a preferred embodiment, as Figure 4 、 Figure 10 and Figure 11 shown, the housing 2 includes a mounting portion 23, a water inlet portion 24 extending downward from the mounting portion 23, and a water outlet portion 25 extending upward from the mounting portion 23. The waste water discharge channel 21 penetrates through the water inlet portion 24, the mounting portion 23, and the water outlet portion 25. The mounting portion 23 is connected to the faucet housing 1. The flow rate adjusting member 4 is disposed in the mounting portion 23, and the waste water regulating valve 3 is disposed in the water inlet portion 24 or in the water outlet portion 25. Those skilled in the art can understand that the downward extension of the water inlet portion 24 facilitates the connection with the waste water inlet pipe 6 of the water purifier, and the upward extension of the water outlet portion 25 facilitates the setting of the waste water outlet 81 at a relatively high position of the faucet main body 300 to facilitate waste water discharge. The flow rate adjusting member 4 is disposed in the mounting portion 23, and can drive the waste water regulating valve 3 to move up and down in the water inlet portion 24 or in the water outlet portion 25 to achieve the adjustment of the water flow rate, further improving the simplicity of the control adjustment. Figure 4The embodiment in which the waste water regulating valve 3 is arranged in the water inlet part 24 is shown. In the solution where the waste water regulating valve 3 includes a valve core 31 and a valve body 32, when the flow regulating member 4 drives the valve core 31 to move downward, the opening of the regulating channel 33 increases, and when the elastic member 34 drives the valve core 31 to move upward, the opening of the regulating channel 33 decreases.

[0065] As a preferred embodiment under this embodiment, as Figure 4 , Figure 10 and Figure 11 shown, the installation part 23 is provided with an installation hole 26 that penetrates the waste water discharge channel 21 and the outside of the faucet housing 1. One end of the flow regulating member 4 is located outside the faucet housing 1, and the other end passes through the installation hole 26 and enters the waste water discharge channel 21. The flow regulating member 4 can rotate in the installation hole 26 and drive the waste water regulating valve 3 to act during the rotation process. Those skilled in the art can understand that one end of the flow regulating member 4 is located outside the faucet housing 1, so that the flow regulating member 4 can be directly operated outside the faucet housing 1. The other end of the flow regulating member 4 passes through the installation hole 26 and enters the waste water discharge channel 21 to achieve contact with the waste water regulating valve 3. The flow regulating member 4 can rotate in the installation hole 26 and drive the waste water regulating valve 3 to act during the rotation process. Moreover, by limiting the flow regulating member 4 within the rotational freedom, rotating the flow regulating member 4 in one direction can make the waste water regulating valve 3 act in the direction of increasing the water flow rate, and rotating in the opposite direction can make the waste water regulating valve 3 act in the direction of decreasing the water flow rate. The operation is simple, the movement range of the flow regulating member 4 is small, and the faucet main body 300 has a more compact structure. In this embodiment, since the flow regulating member 4 is limited within the rotational freedom, in the solution where the adjusting part 41 is provided on its outer side wall as described above, the adjusting part 41 is provided with a structure extending along its circumferential direction.

[0066] Furthermore, as Figure 1 , Figure 4 and Figure 6 shown, a knob 7 is installed at one end of the flow regulating member 4 located outside the faucet housing 1, so that the flow regulating member 4 can be rotated by operating the knob 7, improving the operation convenience. The knob 7 and the flow regulating member 4 can be relatively fixed in the circumferential direction through a flat hole fit.

[0067] In addition, as Figure 4 , Figure 9 and Figure 11As shown, one end of the flow regulator 4 located within the wastewater discharge passage 21 is provided with a rotating hole 42, and the inner wall of the wastewater discharge passage 21 is provided with a protruding rotating shaft 27. The rotating hole 42 is in rotational fit with the rotating shaft 27. Specifically, during installation, when inserting the flow regulator 4 into the installation hole 26, the rotating shaft 27 just inserts into the rotating hole 42, forming a stop limit for the rotating shaft 27, and can also guide the rotation of the flow regulator 4 through the cooperation of the rotating shaft 27 and the rotating hole 42.

[0068] In a preferred embodiment, as Figure 3 , Figure 4 , Figure 6 and Figure 10 shown, the faucet housing 1 is provided with a first avoidance hole 11. A partial area of the installation part 23 extends out of the faucet housing 1 from the first avoidance hole 11 and is connected with a first positioning member 9. The first positioning member 9 abuts against the outer wall of the faucet housing 1 to limit the installation part 23. The first positioning member 9 is provided with a stop wall 91, and the stop wall 91 abuts against the flow regulator 4 to limit the axial movement of the flow regulator 4. Those skilled in the art can understand that the first positioning member 9 abuts against the outer wall of the faucet housing 1 to limit the installation part 23, and also abuts against the flow regulator 4 through the stop wall 91 to limit the axial movement of the flow regulator 4. Therefore, the first positioning member 9 not only realizes the limitation of the installation part 23, restricts the installation part 23 within the first avoidance hole 11 to prevent it from retracting into the faucet housing 1, but also, by restricting the axial movement of the flow regulator 4, ensures that the flow regulator 4 is stable within the installation hole 26 to guarantee the effectiveness of the water flow regulation. Specifically, the first positioning member 9 can be threadedly connected to the installation part 23 to improve the assembly convenience. During specific installation, first extend the installation part 23 out of the first avoidance hole 11, then insert the flow regulator 4 into the installation hole 26, and then screw the first positioning member 9 onto the installation part 23 until it abuts against the outer wall of the faucet housing 1 to simultaneously form a restriction on the flow regulator 4 and the installation part 23. Finally, install the knob 7 on the outer end of the flow regulator 4. In addition, as Figure 12 and Figure 13 shown, a stop rib 71 can be provided inside the knob 7, and a stop groove 92 can be provided outside the first positioning member 9, so that the stop rib 71 and the stop groove 92 cooperate to limit the rotation angle of the knob 7.

[0069] As a preferred embodiment under this embodiment mode, as Figure 3 and Figure 4As shown, the faucet housing 1 is provided with a second avoidance hole 12. The faucet body 300 further includes an adapter 8. One end of the adapter 8 is connected to the water outlet part 25, and the other end extends out of the faucet housing 1 from the second avoidance hole 12 and is connected with a second positioning member 100. The waste water discharge port 81 is formed in the adapter 8. The second positioning member 100 abuts against the outer wall of the faucet housing 1 to limit the adapter 8. Specifically, the adapter 8 can be an L-shaped adapter, which is convenient for one end to be connected to the upward extending water outlet part 25 of the housing 2, and the other end to pass horizontally through the second avoidance hole 12 on the side of the faucet housing 1. The second positioning member 100 abuts against the outer wall of the faucet housing 1 to limit the adapter 8 and prevent it from retracting into the faucet housing 1. Moreover, the limitation of the installation part 23 by the first positioning member 9 and the limitation of the adapter 8 by the second positioning member 100 together realize the positioning of the housing 2 in the faucet housing 1. Specifically, the second positioning member 100 can be threadedly connected to the adapter 8 to improve the assembly convenience. A sealing ring can be arranged between the second positioning member 100 and the adapter 8 to ensure the sealing between the two and prevent waste water from flowing out through the thread gap between the second positioning member 100 and the adapter 8.

[0070] Further, as Figure 1 , Figure 2 and Figure 4 shown, the faucet further includes a waste water outlet pipe 200. One end of the waste water outlet pipe 200 is inserted into the second positioning member 100 and communicated with the adapter 8 to facilitate waste water discharge.
