Description

Technical Field

[0001] This invention relates to the field of faucet technology, and more specifically to a replaceable faucet with a display screen. Background Technology

[0002] Existing faucets with sensor and display functions typically integrate the sensor probe inside the faucet. Their electrical wiring is usually laid out using direct soldering or fixed plug-in methods, resulting in a high degree of overall integration. However, in actual use, electronic components such as the sensor probe may malfunction due to moisture corrosion, circuit aging, or external damage. Because these components are fixedly assembled with the faucet body and internal piping, they lack a quick-disassembly mechanism. This leads to cumbersome and complex operations, sometimes even damaging the original assembly structure, resulting in low replacement efficiency and high maintenance costs. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this invention is to propose a replaceable faucet with a display screen to solve the problems mentioned in the background section above.

[0004] This invention is achieved through the following technical solution: A replaceable faucet with a display screen includes a faucet body, a sensing module, and a power supply module. The sensing module includes a mounting base, which is detachably connected to the faucet body. The mounting base is fixed with a first wire and a sensing probe. The first wire is connected to a second wire passing through the faucet body. The end of the second wire away from the first wire is connected to the power supply module. By pulling the mounting base, the connection point between the first and second wires can be exposed on the faucet body.

[0005] Furthermore, it also includes a display module, which is detachably connected to the faucet body. The display module includes a third wire, which is connected to a fourth wire passing through the faucet body. The end of the fourth wire away from the third wire is connected to the power supply module. By pulling the display module, the connection point between the third wire and the fourth wire can be exposed to the faucet body.

[0006] Furthermore, the faucet body is provided with a mounting groove, the display module is embedded in the mounting groove, and the display module includes a sealing ring that seals against the inner wall of the mounting groove.

[0007] Furthermore, it also includes a water supply assembly, which includes a valve core seat and a temperature regulating valve core connected to the valve core seat. The valve core seat has multiple water passage holes that communicate with the temperature regulating valve core. The water supply assembly also includes multiple water pipes, each of which is inserted into the water passage hole, and each water pipe has an annular groove at one end extending out of the water passage hole. The water supply assembly also includes a retaining plate, which has a retaining part adapted to the annular retaining groove. The retaining plate is detachably connected to the valve core seat to restrict the water pipe from coming out of the water passage hole.

[0008] Furthermore, the temperature control valve core includes a manually controlled water outlet and an electrically controlled water outlet; The water passage includes a cold water inlet channel, a hot water inlet channel, and a mixing water outlet channel. The mixing water outlet channel includes a manually controlled channel, an electrically controlled channel, a mixing chamber, a transition channel, and a water outlet channel. The manually controlled channel connects the manually controlled water outlet and the mixing chamber. The electrically controlled channel connects the electrically controlled water outlet and the transition channel. The transition channel connects the mixing chamber, and the mixing chamber connects to the water outlet. The water pipe includes a cold water pipe, a hot water pipe, and a pull-out pipe. The cold water pipe is inserted into the cold water inlet channel, the hot water pipe is inserted into the hot water inlet channel, and the pull-out pipe is inserted into the water outlet channel. The water supply assembly also includes a solenoid valve. When the faucet is in manual water dispensing mode, the solenoid valve remains normally closed to isolate the water path between the transition channel and the mixing chamber. When the faucet is in electronically controlled water dispensing mode, the solenoid valve can switch between the on and off states to control the start and stop of water dispensing.

[0009] Furthermore, the faucet body includes a lower outer shell and an upper outer shell. The upper outer shell is assembled at the upper end of the lower outer shell, and the upper outer shell can rotate relative to the lower outer shell to adjust the water outlet direction. A water outlet is provided inside the upper outer shell, and the pull tube is connected to the water outlet. The water outlet can be pulled out of the upper outer shell. The fixing seat is sleeved on the outside of the water outlet head and is built into the upper outer shell; the sensing module also includes two symmetrically arranged telescopic parts, which are elastically connected to the fixing seat and are used to snap onto the upper outer shell.

[0010] Furthermore, the lower outer shell is provided with an eccentric hole and a clearance groove, the pull tube passes through the eccentric hole, and the second and fourth wires pass through the clearance groove.

[0011] Furthermore, it also includes at least one water purification pipeline, one end of which is connected to the fixed base, and the other end of which is connected to the water purification equipment.

[0012] Furthermore, the display module includes a first control switch, which is used to control the opening and closing of the sensing module.

[0013] Furthermore, the sensing probe includes two laser chips, which work together to prevent the sensing probe from self-excited.

[0014] The beneficial effects of this invention are as follows: A replaceable faucet with a display screen includes a faucet body, a sensing module, and a power supply module. The sensing module includes a mounting base, which is detachably connected to the faucet body. The mounting base is fixed with a first wire and a sensing probe. The first wire is connected to a second wire passing through the faucet body. The end of the second wire away from the first wire is connected to the power supply module. By pulling the mounting base, the connection point between the first and second wires can be exposed on the faucet body. This invention, by employing a detachable mounting base structure for the sensing module, eliminates the need to completely disassemble the faucet body when the sensing module is damaged, significantly reducing the difficulty of maintaining and replacing the sensing probe.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of aiding understanding the present invention, but does not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0027] Reference Figures 1 to 10 As shown, a replaceable faucet with a display screen includes a faucet body 1, a sensing module 2, a display module 3, and a power supply module. The sensing module 2 includes a fixing base 21, which is detachably connected to the faucet body 1. The fixing base 21 is fixed with a first wire 22 and a sensing probe 24. The first wire 22 is connected to a second wire 23 that passes through the faucet body 1. The end of the second wire 23 away from the first wire 22 is connected to the power supply module. By pulling the fixing base 21, the connection part of the first wire 22 and the second wire 23 can be exposed to the faucet body 1. The display module 3 is detachably connected to the faucet body 1. The display module 3 includes a third wire 31, which is connected to a fourth wire 32 passing through the faucet body 1. The end of the fourth wire 32 away from the third wire 31 is connected to the power supply module. By pulling the display module 3, the connection part of the third wire 31 and the fourth wire 32 can be exposed to the faucet body 1.

[0028] Reference Figures 2 to 4 As shown, when the sensing module 2 is damaged and requires maintenance, first remove the fixing base 21 from the faucet body 1, then pull the fixing base 21 outwards to expose the connection point between the first wire 22 and the second wire 23 to the outside of the faucet body 1. Then, separate and disassemble the first wire 22 and the second wire 23 to allow for individual replacement or repair of the sensing module 2. The operation is simple and quick. The first wire 22 and the second wire 23 are electrically connected via a quick-connect conductive connector, forming a conductive path when plugged in and disconnecting to break the circuit. Therefore, after pulling out the fixing base 21, the wiring can be easily installed and removed.

[0029] Similarly, when the display module 3 is damaged and requires maintenance, first remove the display module 3 from the faucet body 1, then pull the display module 3 outwards, exposing the connection point of the third wire 31 and the fourth wire 32 to the outside of the faucet body 1. Then, separate and disassemble the third wire 31 and the fourth wire 32, allowing the display module 3 to be replaced or repaired individually. The operation is simple and quick. The third wire 31 and the fourth wire 32 are also electrically connected using a quick-connect conductive connector, forming a conductive path when plugged in and disconnecting to break the circuit. This allows for convenient wiring and disassembly operations after pulling out the display module 3.

[0030] Preferably, the power supply module can be arranged in the space under the basin where the faucet is installed. The power supply module is electrically connected to the control unit, display module 3, sensing module 2 and solenoid valve 43 to provide a stable working power supply for each electrical component.

[0031] In summary, this invention adopts a detachable installation structure for the sensing module 2 and the display module 3, and uses quick-connect conductive connectors to achieve rapid wire connection. When the sensing module 2 or the display module 3 malfunctions, it is only necessary to remove the corresponding module and pull it outward to expose the wiring part. There is no need to disassemble the faucet body and internal pipes. The disassembly and assembly process does not require welding or special tools, making maintenance simple and efficient, and facilitating the quick replacement of damaged parts.

[0032] This invention adopts a detachable installation structure for the sensing module 2 and the display module 3, and uses a quick-connect conductive connector to achieve rapid wire connection. When the sensing module 2 or the display module 3 malfunctions, it is only necessary to remove the corresponding module and pull it outward to expose the wiring part. There is no need to disassemble the faucet body and internal pipelines. The disassembly and assembly process does not require welding or special tools, making maintenance simple and efficient, and facilitating the quick replacement of damaged parts.

[0033] Reference Figure 2 As shown, the faucet body 1 is further provided with a mounting groove 121, and the display module 3 is embedded in the mounting groove 121. The display module 3 includes a sealing ring that seals against the inner wall of the mounting groove 121. By using the sealing ring to seal against the inner wall of the mounting groove 121, a reliable sealing structure can be formed between the display module 3 and the faucet body 1, effectively preventing external moisture, water mist, and water stains from entering the mounting groove 121 and the interior of the faucet body 1. This avoids moisture corrosion of the internal circuitry and conductive connectors of the display module 3, thereby preventing problems such as short circuits, poor contact, and component corrosion. This significantly improves the waterproof performance and operational stability of the display module 3 and the entire faucet, and extends the product's service life.

[0034] The faucet body 1 includes an upper outer shell 11 and a lower outer shell 12. The upper outer shell 11 is mounted on the upper end of the lower outer shell 12, and the upper outer shell 11 can rotate relative to the lower outer shell 12 to adjust the water outlet direction. The upper outer shell 11 is provided with a water outlet head 13, which can be pulled out of the upper outer shell 11 to adjust the water outlet range and usage position.

[0035] The present invention is improved as follows: the fixing seat 21 is sleeved on the outside of the water outlet head 13, and the fixing seat 21 is built into the upper outer shell 11; the sensing module 2 also includes two symmetrically arranged telescopic parts 25, and the telescopic parts 25 are elastically connected to the fixing seat 21. When the telescopic parts 25 are not pressed, the outer side of the telescopic parts 25 is flush with the outer wall surface of the upper outer shell 11 and smoothly transitions, achieving a continuous overall appearance; when the telescopic parts 25 are pressed inward, the telescopic parts 25 elastically contract and retract to the inner side of the upper outer shell 11, releasing the limiting fit between them. At this time, the fixing seat 21 and the sensing module 2 can be pulled out from the upper outer shell 11 together, realizing the quick disassembly and separation of the fixing seat 21 and the upper outer shell 11.

[0036] Reference Figure 4As shown, the telescopic part 25 has a built-in elastic reset member. One end of the elastic reset member abuts against the fixed seat 21, and the other end abuts against the telescopic part 25, so that the telescopic part 25 maintains an outward extension tendency in its natural state and forms a snap-fit ​​limit with the upper outer shell 11. When an inward pressing force is applied to the telescopic part 25, the telescopic part 25 compresses the elastic reset member and retracts towards the fixed seat 21, thereby disengaging from the limiting structure of the upper outer shell 11. After the telescopic part 25 is released, under the action of the elastic reset member, the telescopic part 25 automatically resets outward and re-establishes the snap-fit ​​fixation with the upper outer shell 11.

[0037] The press-type telescopic part 25 is used to achieve the detachable snap-fit ​​connection between the fixed base 21 and the upper outer shell 11. No tools are needed for disassembly and assembly. Disassembly and assembly can be completed by simply pressing and pulling. The operation is simple and quick, which facilitates the rapid inspection or replacement of the sensing module 2.

[0038] Reference Figure 1 As shown, the telescopic part 25 smoothly transitions with the outer wall of the upper shell 11 in its natural state, making the overall appearance of the faucet simple and smooth, and improving the overall appearance and aesthetics of the product.

[0039] The fixing seat 21 is sleeved on the outside of the water outlet 13, and the upper outer shell 11 is sleeved on the outside of the fixing seat 21. The sensing module 2 includes two telescopic parts 25. When the telescopic parts 25 are not pressed, the outer side of the telescopic parts 25 smoothly transitions with the upper outer shell 11. When the telescopic parts 25 are pressed, they retract to the inside of the upper outer shell 11, thereby pulling the fixing seat 21 out of the upper outer shell 11 and disassembling the fixing seat 21 from the upper outer shell 11.

[0040] Reference Figures 5 to 10 As shown, in order to realize the water outlet function of the water outlet 13, the faucet of the present invention also includes a water supply component 4, which includes a valve core seat 41 and a temperature regulating valve core 42 connected to the valve core seat 41.

[0041] The valve core seat 41 has multiple water passage holes 411 that communicate with the temperature regulating valve core 42; the water supply assembly 4 also includes multiple water pipes 44, each of which is inserted into the water passage hole 411, and each of the water pipes 44 has an annular groove 444 at one end extending out of the water passage hole 411; the water supply assembly 4 also includes a retaining plate 47, which has a retaining part that matches the annular groove 444. The retaining plate 47 and the valve core seat 41 can be detached and connected by screws or other parts, so as to restrict the water pipes 44 from coming out of the water passage hole 411.

[0042] With the above structure, the water pipe 44 and the valve core seat 41 can achieve universal rotational fit. Several sealing rings are sleeved on the outer periphery of the water pipe 44. The sealing rings are pressed against the inner wall of the water passage hole 411 to achieve sealing. The water pipe 44 is axially limited by the clamping plate 47, so that the water pipe 44 can rotate freely relative to the valve core seat 41 without coming out of the water passage hole 411.

[0043] The water pipe 44 and the valve core seat 41 can be omnidirectionally rotated. The outer circumference of the water pipe 44 is fitted with several sealing rings, which are pressed against the inner wall of the water passage hole 411 to achieve a seal. The water pipe 44 is axially limited by the clamping plate 47, so that the water pipe 44 can rotate freely relative to the valve core seat 41 without coming out of the water passage hole 411.

[0044] Compared to existing technologies, this structure eliminates the need for threaded inserts at the connection between the water pipe 44 and the valve core seat 41, maximizing the wall thickness of the valve core seat 41. This results in higher structural strength under high-pressure water flow, reducing the likelihood of deformation, cracking, and leakage. Furthermore, when the other end of the water pipe 44 is connected to the angle valve via a threaded ring and rotates, the connection between the water pipe 44 and the valve core seat 41 is merely a rotational fit rather than a threaded connection. This prevents the connection from loosening due to torsional stress, effectively avoiding pipe detachment and leakage, and enhancing the stability and reliability of the water supply structure.

[0045] The temperature control valve core 42 is prior art, and the valve core structure disclosed in Chinese patent document CN212672445U can be referred to. This temperature control valve core 42 includes a manually controlled water outlet 421 and an electrically controlled water outlet 422. Correspondingly, the water passage 411 of the valve core seat 41 specifically includes a cold water inlet channel 4111, a hot water inlet channel 4112, and a mixed water outlet channel 4113. The mixed water outlet channel 4113 includes a manually controlled... The system includes a manual flow channel 41131, an electrically controlled flow channel 41132, a mixing chamber 41133, a transition flow channel 41134, and an outlet channel 41135. The manual flow channel 41131 connects to the manual outlet 421 and the mixing chamber 41133. The electrically controlled flow channel 41132 connects to the electrically controlled outlet 422 and the transition flow channel 41134. The transition flow channel 41134 connects to the mixing chamber 41133. The mixing chamber 41133 connects to the outlet.

[0046] The aforementioned water pipe 44 includes a cold water conduit 441, a hot water conduit 442, and a pull-out pipe 443. The cold water conduit 441 and the hot water conduit 442 are respectively used to connect to cold water angle valves and hot water angle valves in households or other usage scenarios. The upper end of the cold water conduit 441 is omnidirectionally fitted with the cold water inlet channel 4111; the upper end of the hot water conduit 442 is omnidirectionally fitted with the hot water inlet channel 4112; and the pull-out pipe 443 is omnidirectionally fitted with the water outlet channel 41135.

[0047] Reference Figure 9 As shown, the red line illustrates the water flow direction in manual water dispensing mode. When the faucet is in manual water dispensing mode, the solenoid valve 43 remains normally closed to isolate the water path between the transition channel 41134 and the mixing chamber 41133. When the user uses the manual water dispensing mode and dispenses water, external cold water enters the temperature regulating valve core 42 through the cold water pipe 441 and the cold water inlet channel 4111, while external hot water enters the temperature regulating valve core 42 through the hot water pipe 442 and the hot water inlet channel 4112. The cold water and hot water are mixed in the temperature regulating valve core 42 according to a set ratio to form warm water. The mixed warm water then flows sequentially through the manual water outlet 421, the manual flow channel 41131, the mixing chamber 41133, the water outlet channel 41135, and the pull-out pipe 443, finally flowing out through the water outlet 13 connected to the pull-out pipe 443.

[0048] Reference Figure 10 As shown, the red line illustrates the water flow direction in the electrically controlled water dispensing mode. When the faucet is in the electrically controlled water dispensing mode, the solenoid valve 43 can switch between the on and off states to control the start and stop of water dispensing. When the solenoid valve 43 is on, the transition channel 41134 and the mixing chamber 41133 are connected to each other to realize induction water dispensing. When the solenoid valve 43 is off, the transition channel 41134 and the mixing chamber 41133 are isolated from each other, and water dispensing stops. When the user uses the electronically controlled water outlet mode and water is dispensed, external cold water enters the temperature regulating valve core 42 through the cold water pipe 441 and the cold water inlet channel 4111, and external hot water enters the temperature regulating valve core 42 through the hot water pipe 442 and the hot water inlet channel 4112. The cold water and hot water are mixed in the temperature regulating valve core 42 according to the set ratio to form warm water. The mixed warm water flows sequentially through the electronically controlled water outlet 422, the electronically controlled channel 41132, the transition channel 41134, the mixing chamber 41133, the water outlet channel 41135, and the pull-out pipe 443, and finally flows out through the water outlet head 13 connected to the pull-out pipe 443.

[0049] When the faucet is in electronically controlled water dispensing mode, the solenoid valve 43 is used to open or close the transition channel 41134 and the mixing chamber 41133. In use, the sensor probe 24 of the sensing module 2 detects the user's approach or hand gestures and transmits the detection signal to the control unit. The control unit controls the solenoid valve 43 to operate based on this signal, opening or closing the transition channel 41134 and the mixing chamber 41133, thereby achieving automatic water dispensing and shut-off of the faucet.

[0050] Reference Figures 7 to 9As shown, the improvement of the present invention is that: the water supply component 4 is further provided with a sensing trigger component 45, the sensing trigger component 45 includes an elastic element 451 and a magnet seat 452 housed in the manual control flow channel 41131, and a magnetic control switch 453 is correspondingly provided on the outside of the valve core seat 41, the magnetic control switch 453 is electrically connected to the control unit; wherein, the elastic element 451 is preferably a spring, the magnet seat 452 includes a magnet and a seat for mounting and fixing the magnet, the magnetic control switch 453 adopts a magnetic control tube in the prior art, and works based on the Hall effect sensing principle. When the magnet approaches the magnetic control switch 453, the magnetic control switch 453 generates a corresponding electrical signal and transmits it to the control unit, the control unit controls the solenoid valve 43 to be in the normally closed state.

[0051] When the temperature regulating valve core 42 is switched to the manual open state, the water circuit is opened, and the water flow acts on the magnet base 452 and pushes it to move, compressing the elastic element 451. The magnet base 452 is displaced to the recognition area of ​​the magnetic control switch 453. After the magnetic control switch 453 senses the magnet, it outputs an electrical signal to the control unit. The control unit controls the solenoid valve 43 to switch to the normally closed state, thereby automatically disabling the sensor-controlled water dispensing function in manual water dispensing mode. By setting the above structure, when the user manually turns on the faucet, the sensor control function is automatically turned off, avoiding the problem of the sensor probe 24 mistakenly detecting actions such as washing hands under the water outlet 13, which could lead to the solenoid valve 43 being mistakenly triggered to dispense water. This ensures stable water dispensing in manual water dispensing mode and eliminates splashing and interference caused by dual water dispensing.

[0052] The improvement of this invention lies in the following: the water supply assembly 4 further includes a partition sleeve 46 that engages with the valve core seat 41, the partition sleeve 46 and the valve core seat 41 forming a partition hole 461; one of the water pipes 44 is a pull-out pipe 443, which passes through the partition hole 461. The partition sleeve 46 independently limits and guides the pull-out pipe 443, allowing the user to ensure a stable and smooth movement path of the pull-out pipe 443 during its movement via the water outlet 13. This prevents interference, compression, or entanglement between the pull-out pipe 443 and the second conductor 23 and the fourth conductor 32, ensuring flexible and reliable pulling action, stable electrical wiring connections, and improved overall faucet reliability.

[0053] Reference Figure 2As shown, the improvement of the present invention is that: at least two purified water pipes 44 are arranged outside the partition sleeve 46. One end of the purified water pipe 44 is connected to the fixed base 21, and the other end of the purified water pipe 44 is connected to the water purification equipment. The two purified water pipes 44 are set independently. Both purified water pipes 44 are used to connect to the external water purification equipment. One of them is a room temperature purified water outlet pipe 44, which is used to directly transport room temperature purified water after treatment by the water purification equipment. The other is a reserved pipe, which can selectively connect to the ice water or sparkling water output by the water purification equipment according to actual use needs to realize the transportation of ice water or sparkling water. The two pipes are independent of each other, which can realize the independent supply and switching of multiple purified water. Furthermore, both purified water pipes 44 are set outside the partition sleeve 46 to avoid interference between the purified water pipes 44 and the pull-out pipe 443.

[0054] Two water purification pipes, each with 44 lines, are connected to the water purifier. One of them is a room temperature purified water outlet pipe, used to output room temperature purified water. The other is a reserved pipe that can be adapted to connect to ice water or sparkling water according to usage needs, so as to realize the independent delivery and switching of multiple purified water lines.

[0055] One end of the water purification pipe 44 is connected to the fixed base 21. The water outlet 13 will not move the water purification pipe 44 during the pulling process, so as not to affect the connection stability and water supply of the water purification pipe 44, and avoid leakage, blockage or detachment of the pipe due to pulling or twisting, thus ensuring continuous and reliable water purification output.

[0056] Reference Figure 2 As shown, the improvement of the present invention lies in the following: the lower outer shell 12 is provided with an eccentric hole 122 and a clearance groove 123. The pull-out tube 443 passes through the eccentric hole 122, and the water purification pipe 44, the second wire 23, and the fourth wire 32 pass through the clearance groove 123. The eccentric hole 122 and the clearance groove 123 separate the pull-out tube 443 from the water purification pipe 44, the second wire 23, and the fourth wire 32. The user, through the water outlet 13, ensures a stable and smooth movement path for the pull-out tube 443 during its movement, preventing interference, compression, or entanglement between the pull-out tube 443 and the water purification pipe 44, the second wire 23, and the fourth wire 32. Simultaneously, the eccentric arrangement of the pull-out tube 443 fully utilizes the internal space of the shell, making the overall layout more compact and reasonable, and improving space utilization.

[0057] Reference Figure 9 As shown, the improvement of the present invention is that a flow sensor 48 is provided in the mixed water flow channel 4113. As a preferred embodiment, the flow sensor 48 is arranged in the water outlet channel 41135, which can ensure that all water flowing through the mixed water flow channel 4113 and output outward passes through the detection area of ​​the flow sensor 48, so as to achieve complete and accurate measurement of water consumption without any measurement omissions.

[0058] The flow sensor 48 collects real-time water flow data through the mixing outlet channel 4113 and transmits the corresponding flow signal to the control unit. The control unit calculates, accumulates, and processes the received real-time flow signal, and then transmits the water consumption data to the display module 3 for real-time visual display. Users can intuitively view the current instantaneous water consumption and cumulative water consumption through the display module 3, and can also realize data management such as daily water consumption statistics and monthly water supply summary, which facilitates real-time monitoring of water consumption and achieves refined water-saving management 44.

[0059] The pull-out tube 443 is sealed and abuts against the inner wall of the water outlet channel 41135 of the valve core seat 41 via an eccentric fitting 4431. Since the outer diameter of the flow sensor 48 is larger than the outer diameter of the pull-out tube 443, the pull-out tube 443 is connected to the valve core seat 41 by setting the eccentric fitting 4431, and the installation position of the pull-out tube 443 is offset to the inside of the mounting screw tube 14 by the eccentric fitting 4431, so as to avoid structural interference between the pull-out tube 443 and the mounting screw tube 14.

[0060] The eccentric pipe fitting 4431 can be detachably connected to the valve core seat 41 by screws. During assembly, first, the flow sensor 48 is installed into the mixing water channel 4113, then the eccentric pipe fitting 4431 is assembled into the mixing water channel 4113, then the pull tube 443 is inserted into the eccentric pipe fitting 4431, and finally the clamping plate 47 is fixedly connected to the valve core seat 41 to complete the assembly and positioning.

[0061] Reference Figure 7 As shown, the improvement of the present invention is that: a temperature sensor 49 is installed on the valve core seat 41, one end of which extends into the mixed water flow channel 4113, so as to detect the outlet temperature of the mixed water in real time and transmit the temperature signal to the control unit.

[0062] Preferably, the sensing section of the temperature sensor 49 extends directly into the mixing chamber 41133. Since the mixing chamber 41133 has ample space, the sensing section can fully contact the thoroughly mixed water, effectively improving the accuracy and response speed of temperature detection. After processing and converting the received temperature signal, the control unit transmits the water temperature data to the display module 3 for real-time digital display, allowing users to intuitively view the current outlet water temperature, achieving visualized water temperature monitoring, and improving safety and ease of operation.

[0063] The improvement of this invention lies in that: the display module 3 includes a first control switch 33, which is used to control the opening and closing of the sensing module 2. When wiping or cleaning the outer surface of the faucet, the user can pre-close the sensing module 2 through the first control switch 33, thereby avoiding accidental water discharge caused by the hand approaching the sensing probe 24, making the cleaning process more convenient and clean, and preventing water splashing due to sensor malfunction.

[0064] The improvement of the present invention is that the display module 3 includes a second control switch 34, which is electrically connected to the food waste disposer via wired or wireless communication, and is used to control the start and stop of the food waste disposer, so as to realize convenient operation of the food waste disposer.

[0065] The improvement of this invention lies in the following: the sensing probe 24 includes two laser chips 241, which synchronously acquire detection signals; the control unit is configured to determine a valid trigger signal only when both laser chips 241 simultaneously detect the user's hand, and a detection signal from a single laser chip 241 will not trigger the water dispensing action. Through the joint logic judgment of the dual laser chips 241, the self-excitation phenomenon caused by false detection of a single probe due to environmental reflection, water droplet splashing, light interference, etc., is avoided, thereby effectively preventing false triggering, continuous triggering, or random triggering of the sensing probe 24, and improving the reliability and anti-interference capability of the sensing control.
