Description

Technical field

[0001] This utility model relates to the field of faucets. In particular, this utility model relates to an intelligent, multifunctional faucet. background

[0002] As society develops and living standards rise, so do people's demands for quality of life. However, existing traditional bathroom and kitchen faucets only provide cold or hot and cold tap water, which is not well suited to this higher standard of living. With rising living standards, people are placing greater demands on the quality of their drinking water. To meet market demand, faucets capable of dispensing multiple types of water have already been developed – such as the faucet disclosed in patent number CN218845193U, which integrates cold and hot tap water as well as cold and hot purified water into a single unit.It comprises a faucet body and a control unit: The faucet body consists of a kitchen faucet structure for dispensing cold and hot tap water and a purified water structure for dispensing cold and hot purified water; the control unit comprises a valve body receptacle and a valve body. The kitchen faucet structure is screwed to the valve body receptacle, and the valve body is connected to the valve body receptacle via a press-fit cap and a handle. This faucet integrates cold and hot tap water as well as cold and hot purified water into a single unit, while also offering features such as rinse water dispensing, microbubble water dispensing, and cold and hot purified water to meet the diverse needs of consumers. An electronic control component for securing the power and signal lines is located above the internal structure, and a touch panel is situated above the electronic control component.Through data exchange between the electronic components and the water purifier, information such as the water quality, the temperature system heating, and the filter media lifespan are displayed on the touch panel. The panel displays the following information: cold purified water dispensing button, warm purified water dispensing button, input TDS value, output TDS value, lock button, heating button, water temperature display, low water level indicator, and filter media lifespan indicator. During operation, the desired purified water state (cold water, warm water, bubble water), flow rate, and temperature are selected to obtain the desired purified water.

[0003] In the aforementioned design, however, the selection of pure water relies entirely on the touch panel, and the touch panel presents several problems in its use, primarily as follows: Firstly, the touch panel implements its functions by detecting the touch position and the touch action, thus increasing the likelihood of incorrect operation. Compared to conventional mechanical buttons, the touch panel offers no tactile feedback like pressing a physical button, so the user may be unsure whether they have successfully triggered a specific function and therefore repeatedly presses the button, resulting in low usage efficiency. Secondly, the manufacturing technology of the touch panel is relatively complex – especially for high-precision and highly sensitive touch panels, advanced materials and manufacturing techniques are required.This results in high manufacturing costs for the touch panel, which in turn makes the price of devices with touch panels relatively high. Furthermore, repair costs are also considerable if the device's touch panel fails, as repairs require qualified personnel and equipment.

The third sealing ring 45 rests tightly against the inner wall of the inlet hole 38 to ensure a tight seal.

[0045] A foam generator 33 is arranged at the inlet hole 38 corresponding to the cold clean water pipe 28. The upper part of the foam generator 33 is provided with a flexible sealing material (e.g., rubber) so that the top of the foam generator 33 is tightly connected to the corresponding inlet hole 38. The outer wall of the middle and lower parts of the foam generator 33 is threaded, and the inner wall of the corresponding mounting hole has a thread matching this thread – thus, the middle and lower parts of the foam generator 33 are screwed into the corresponding mounting hole. Both the lower side of the hot water outlet nozzles 32 and the lower side of the foam generator 33 are located within the area of ​​the water outlet opening.

[0046] This technical solution, through the design of the decorative cover 30, the fixing block 31, the first mounting block 291, the second mounting block 292, the insertion holes 38, the mounting holes, the hot water outlet nozzle 32, and the foam generator 33, provides a mounting pipe structure and a mounting station structure that is easy to assemble and disassemble, thus facilitating maintenance. Simultaneously, the stainless steel filter 37, associated with the hot water pipe 27, interrupts bubbles in the hot water and prevents boiling water from splashing and causing burns. The stainless steel filter 37 and the foam generator 33, associated with the cold water pipe 28, ensure a soft and splash-free water flow.

[0047] In another technical solution, the faucet further comprises a fixing plate 34 and a locking nut 35. The size and shape of the fixing plate 34 are adapted to the size and shape of the water outlet opening, and a first water outlet opening (associated with the hot water outlet nozzle 32) and a second water outlet opening 48 (associated with the foam generator 33) are formed on the fixing plate 34. One end of the locking nut 35 is coaxially fixed to a connecting ring 36, and the connecting ring 36 is rotatably connected to the first water outlet opening. The lower part of the hot water outlet nozzle 32 is provided with a thread that is adapted to the locking nut 35. When the locking nut 35 is screwed onto the hot water outlet nozzle 32, the fixing plate 34 is located in the water outlet opening, and the base of the fixing plate 34 is flush with the base of the water outlet opening.

[0048] In this technical solution, the first water outlet opening on the fixing plate 34 corresponds to the lower side of the hot water outlet nozzle 32, and the second water outlet opening 48 corresponds to the lower side of the foam generator 33. One end of the fixed nut 35 is coaxially connected to a connecting ring 36, and the connecting ring 36 is rotatably connected to the first water outlet opening (the rotatable connection can be a clamping connection). The outer wall of the lower part of the hot water outlet nozzle 32 is threaded. When the fixed nut 35 is screwed onto the hot water outlet nozzle 32, the fixing plate 34 is located in the water outlet opening, its base being flush with the base of the water outlet opening, and the lower side of the foam generator 33 is coaxially connected to the second water outlet opening 48.During use, cold purified water flows out through the foam generator 33 and the second water outlet opening 48, while warm purified water exits through the hot water outlet nozzles 32, the locking nut 35, and the first water outlet opening. For practical application—to rotate the connecting ring 36 and thus screw the locking nut 35 onto the hot water outlet nozzle 32—auxiliary bores can be formed on the underside of the connecting ring 36. By inserting an external connecting tube into the auxiliary bores and rotating the connecting tube, the connecting ring 36 can be guided and rotated.

[0049] This technical solution provides a method for covering the water outlet opening through the design of the fixing plate 34, the fixed nut 35, the first water outlet opening, and the second water outlet opening 48. Since the fixing plate 34 is designed without screw holes for fixing, the product has a more aesthetically pleasing appearance.

[0050] In another technical solution, the vertical tube 41 is a stepped tube: The large diameter tube body of the vertical tube 41 is rotatably and tightly connected to the vertical tube body of the triple tube 22, and the small diameter tube body of the vertical tube 41 is located at the bottom of the large diameter tube body.

[0051] The outlet pipe comprises a first connecting pipe 39, a second connecting pipe 40, and an elbow pipe 43: One end of the first connecting pipe 39 is tightly connected to the outlet side of the mixing valve; the second connecting pipe 40 is tightly connected to the end of the first connecting pipe 39 furthest from the mixing valve, and the upper part of the second connecting pipe 40 projects into the large-diameter body of the vertical pipe 41 after passing through the small-diameter body of the vertical pipe 41. The diameter of the elbow pipe 43 is smaller than the inner diameter of the large-diameter body of the vertical pipe 41, and the lower part of the elbow pipe 43 projects into the large-diameter body of the vertical pipe 41 and is screwed to the upper part of the second connecting pipe 40.

[0052] In the above technical solution, the vertical tube 41 comprises a large-diameter tube body and a small-diameter tube body, arranged sequentially from top to bottom and coaxially connected to each other – both forming a stepped tube structure. The large-diameter tube body is rotatably and tightly inserted into the top of the vertical tube body of the triple tube 22, and the small-diameter tube body hangs freely within the vertical tube body of the triple tube 22.

[0053] The first connecting pipe 39 and the second connecting pipe 40 of the outlet pipe are both arranged vertically: The bottom of the first connecting pipe 39 is tightly connected to the mixed water outlet side of the valve body base 23 (this can be a threaded sealing connection or a press fit); the top of the first connecting pipe 39 is tightly connected to the bottom of the second connecting pipe 40 (this can also be a threaded sealing connection or a press fit). The top of the second connecting pipe 40 extends tightly through the small-diameter pipe body and is then located within the large-diameter pipe body.Specifically, an annular groove is formed on the second connecting pipe 40, in which a fourth sealing ring 46 is arranged - the fourth sealing ring 46 lies close to the inner wall of the small diameter pipe body to ensure a seal between the second connecting pipe 40 and the small diameter pipe body.

[0054] The curved tube 43 is a flexible hose made of silicone material, the diameter of which is preferably 3 to 5 mm smaller than the inner diameter of the large-diameter tube body. An internal thread is formed on the inner wall of the lower part of the curved tube 43, and an external thread matching this internal thread is formed on the outer wall of the upper part of the second connecting tube 40. This allows the lower part of the curved tube 43 to project into the large-diameter tube body and be screwed to the upper part of the second connecting tube 40. A further annular groove is formed on the side wall of the second connecting tube 40, which is located inside the curved tube 43. A fifth sealing ring 47 is arranged in this groove. The fifth sealing ring 47 is located below the external thread and rests tightly against the inner wall of the curved tube 43 to ensure a seal between the second connecting tube 40 and the curved tube 43.The water outlet side of the curved pipe 43 is located on the side where the mounting pipe 42 is located, specifically on the side of the mounting pipe 42 that is away from the connection opening.

[0055] In this technical solution, the water flow occurs as follows: The mixed cold and hot tap water is blended in the mixing valve and then flows out through the first connecting pipe 39, the second connecting pipe 40, and the curved pipe 43. The cold purified water in the cold purified water pipe 28 flows out through the corresponding inlet hole 38, the mounting hole, and the second water outlet opening 48. The hot purified water in the hot purified water pipe 27 flows out through the corresponding inlet hole 38, the mounting hole, the locking nut 35, and the first water outlet opening. To draw purified water, the mounting pipe 42 is rotated to the desired angle, and then the rotary control and the pressure-resetting control are operated to select the desired purified water flow.If tap water is to be drawn, the curved tube 43 is rotated to the desired angle, and then the control handle 24 is operated to draw the desired tap water.

[0056] This technical solution, through the design of the stepped pipe, the first connecting pipe 39, the second connecting pipe 40, and the curved pipe 43, provides a structure for the outlet pipe as well as a sealing connection between the vertical pipe 41 and the outlet pipe. This facilitates assembly and ensures a good seal at all connection points, thus effectively preventing leaks.

[0057] In another technical solution, the faucet further includes a shower head 44, which is arranged at the end of the curved pipe 43 furthest from the second connecting pipe 40. Specifically, the shower head 44 can be designed as a two-way shower head (it can deliver two water forms, namely aerated water and jet water). Together with the curved pipe made of silicone material, this allows users to use the shower head 44 at any angle and in any direction, thus improving usability and practicality.

[0058] In another technical solution, first magnets 51 are arranged in the outer circumferential wall of the shower head 44, and second magnets 52 are arranged in the decorative cover 30. The first magnet 51 and the second magnet 52 have opposite polarities, so that the shower head 44 is magnetically connected to the decorative cover 30. Specifically, the shower head 44 is cylindrical, and the outer wall of the decorative cover 30, which is furthest from the mounting tube 42, is shaped to fit the shower head 44. The first magnets 51 are embedded in the outer wall of the shower head 44, which faces the decorative cover 30, and the second magnets 52 are embedded in the outer wall of the decorative cover 30 – both have opposite polarities.When the user moves the shower head 44 near the decorative cover 30 after use, the shower head 44 is automatically secured to the decorative cover 30 by the magnetic attraction between the first magnet 51 and the second magnet 52, thus achieving automatic reset. This technical solution, through the design of the first magnet 51 and the second magnet 52, enables the mounting tube 42 with the shower head 44 to be magnetically fixed via the decorative cover 30 when the tap is not in use. This facilitates tidying and improves the aesthetic appearance.

[0059] In another technical solution, the first magnet 51 and the second magnet 52 are made of samarium-cobalt magnets. The first magnet 51 and the second magnet 52 are square-shaped, with sides measuring 15–20 mm and a thickness of 5–8 mm. The outer surfaces of the first magnet 51 and the second magnet 52 are each provided with a copper foil electromagnetic shield, the copper foil being 0.1–0.2 mm thick. Three first magnets 51 are evenly distributed circumferentially within the shower head 44, and three second magnets 52 are evenly distributed at corresponding positions within the decorative cover 30. Among the three first magnets 51 and the three second magnets 52, the magnetic strength of the magnet located in the center position is 30–50% higher than that of the two surrounding magnets.

[0060] In the above technical solution, the first magnet 51 and the second magnet 52 are made of samarium-cobalt (SmCo) magnets, whose Curie temperature is typically above 700 °C. They are therefore suitable for high-temperature environments and maintain stable magnetic performance even at high temperatures. Furthermore, the coercive field strength (Hc) of samarium-cobalt magnets is typically above 1200 kA / m, giving them strong resistance to demagnetization and corrosion. They can be used in harsh environments without additional coating, with SmCo5 and Sm2Co17 being preferred in practical applications.

[0061] The first magnet 51 and the second magnet 52 are both square-shaped, with a side length of 15-20 mm and a thickness of 5-8 mm. For practical purposes, it is sufficient that the magnetic contact area between the first magnet 51 and the corresponding second magnet 52 is not less than 225 mm². 2 is.

[0062] The outer surfaces of the first magnet 51 and the second magnet 52 are each provided with a copper foil electromagnetic shield, the thickness of which is limited to 0.1–0.2 mm. In practical applications, it is preferred that the shielding performance of the copper foil electromagnetic shield in the frequency range from 100 kHz to 100 MHz is not less than 30 dB.

[0063] Furthermore, there are three first magnets 51 and three second magnets 52, corresponding to each other. The three first magnets 51 are uniformly embedded in the side wall of the shower head 44 in the circumferential direction, and three second magnets 52 are embedded in the decorative cover 30 at corresponding positions. In practical application, it is preferred that the magnetic attraction force provided by any one first magnet 51 and any one second magnet 52 is not less than 2 N, so that the total magnetic attraction force of the combination of three first magnets 51 and three second magnets 52 is not less than 6 N.More specifically: Among the three first magnets 51 and the three second magnets 52, the magnetic strength of the first magnet 51 arranged in the central position is 30-50% higher than that of the two surrounding first magnets 51, and the magnetic strength of the second magnet 52 arranged in the central position is 30-50% higher than that of the two surrounding second magnets 52.

[0064] The aforementioned technical solution, through the use of samarium-cobalt magnets, ensures that a stable magnetic attraction is maintained even in high-temperature environments, thus enabling its use in hot water environments. The arrangement of the copper foil electromagnetic shielding effectively reduces electromagnetic interference and improves the stability and safety of the device. The arrangement of three primary magnets 51 and three secondary magnets 52 increases the connection security between the shower head 44 and the decorative cover 30. By designing the magnetic strength of the central magnet to be 30-50% higher than that of the surrounding magnets, the magnetic attraction in the central area is further strengthened, preventing the shower head 44 from slipping off the decorative cover 30.

[0065] In another technical solution, the rotary and pressure-operated electronic handle comprises the following components: - a housing 1, at one end of which a circular recess is formed and at the other end of which a connecting element 5 is arranged for detachable connection with the tap body 3; - a first PCB plate 6, which is fixedly arranged in the housing 1, wherein a pressure-resettable electronic microswitch 7 and a ring encoder 8 coaxial with the circular recess are arranged at the end of the first PCB plate 6 - the ring encoder 8 is plugged around the pressure-resettable electronic microswitch 7, and a connecting seat 9 is coaxially attached to the rotor of the ring encoder 8, the end of which, furthest from the first PCB plate 6, protrudes from the housing 1; - a cylindrical rotary handle 2, one end of which is coaxially connected to the outer wall of the protruding end of the connecting seat 9; - A key component comprising a key plate 10 and a push rod 11: The key plate 10 is located at the end of the rotary handle 2 furthest from the first PCB plate 6; one end of the push rod 11 is connected to the key plate 10, and the other end slides into the center of the ring encoder 8 and is abutted against the pressure-resettable electronic microswitch 7. When the key plate 10 is pressed by an external force, the push rod 11 transmits the external force to the pressure-resettable electronic microswitch 7; when the external force ceases, the push rod 11 and the key plate 10 return to their initial position under the restoring force of the pressure-resettable electronic microswitch 7; - where the screen 4 is arranged on the housing 1.

[0066] In the above technical solution, a circular recess is formed at one end of the housing 1, and a connecting element 5 is arranged at the other end. The shape of the interior of the housing 1 is not restricted; for ease of manufacture, it is preferably cylindrical and injection-molded from a waterproof plastic material with sufficient strength. The structure of the connecting element 5 is designed for easy connection to the tap body 3 – for example, it can be designed as an internally threaded structure that is screwed onto the tap body 3 to create a detachable connection, thus facilitating maintenance and replacement. For practical purposes, a rubber sealing ring can also be provided on the connecting element 5 to ensure the watertightness of the connection and prevent water leakage.

[0067] A first PCB plate 6 is arranged in the housing 1 and can be fastened by screws or snap-fit ​​connections to ensure stable mounting. A pressure-resettable electronic microswitch 7 and a ring encoder 8 are welded to the area of ​​the first PCB plate 6 that is close to the circular recess. The ring encoder 8 is coaxially aligned with the circular recess and inserted around the pressure-resettable electronic microswitch 7; the ring encoder 8 can be selected as a high-precision photoelectric ring encoder 8. A connecting seat 9 is coaxially connected to the rotor (rotating component) of the ring encoder 8, with one end of the connecting seat 9 protruding from the housing 1. A rotary handle 2 is coaxially connected to the protruding end, and the rotary handle 2 can be connected to the connecting seat 9 by screwing or snap-fit ​​connections.By turning the rotary handle 2, the rotor of the ring encoder 8 can be driven via the connecting seat 9, whereupon the ring encoder 8 detects the angular displacement of the rotary handle 2 and generates an electrical signal. This electrical signal can be used to control the function switching (e.g., pure water at room temperature, cold water, warm water, bubble water, etc.) or the parameter adjustment (e.g., temperature, water volume, etc.).

[0068] The key assembly comprises a keypad 10 and a pushrod 11. The keypad 10 can be made of metallic material to facilitate operation by pressing; it can be attached by adhesive or snapped into place at the end of the rotary handle 2 furthest from the first PCB plate 6. The pushrod 11 is located in the rotary handle 2: one end is abutted against the keypad 10, and the other end slides into the center of the ring encoder 8 and abuts the pressure-resettable electronic microswitch 7. When the keypad 10 is pressed by an external force, the pushrod 11 moves toward the pressure-resettable electronic microswitch 7 and depresses it. Upon actuation, the pressure-resettable electronic microswitch generates an electrical signal used to control the selection of the desired functions or parameters.There are various embodiments for the arrangement of the push rod 11 in the rotary handle 2 – for example: One end of the push rod 11 is arranged on the side wall of the keypad 10, which faces the first PCB plate 6, and the other end slides into the ring encoder 8. The inserted part is adapted to the inner ring of the ring encoder 8 (the shaft body in the stator coaxial with the rotor), so that the inner ring of the ring encoder 8 forms a guide for the push rod 11 and ensures the accuracy of the transmission of the external force.

[0069] Screen 4 is mounted on housing 1 – specifically, it can be inserted into the prepared groove of housing 1. Screen 4 can be selected as a high-resolution OLED screen to achieve a high-resolution display effect and enhance the visual user experience. It can display various information such as the current function and temperature, allowing the user to monitor the device's status at any time. When the user operates the rotary handle 2 to switch or select a function, the corresponding information is displayed on screen 4.

[0070] In the aforementioned technical solution, the operating procedure is as follows: When the user wishes to switch the functions or parameters of the faucet, they monitor the screen 4 and turn the rotary handle 2. The rotary handle 2 simultaneously rotates the connecting seat 9 and the rotor of the ring encoder 8. The ring encoder 8 converts the angular displacement signal, based on the rotation angles of the rotor, into electrical signals that control the function switching or parameter adjustment and are displayed on the screen. Using the display on screen 4, the user can operate the rotary handle 2 to switch between the different functions or parameters until the desired option is found. To confirm the selection of a specific function or parameter, the user simply presses the keypad 10.The external force is transmitted via the pushrod 11 to the pressure-resettable electronic microswitch 7, causing the microswitch to close instantly and generate a selection electrical signal to lock the currently selected functions / parameters. When the external force ceases, the pressure-resettable electronic microswitch springs back due to its own elasticity, actuating the pushrod 11 and the keypad 10 to reset and prepare for the next operation.

[0071] With this technical solution, the design of the housing 1, the circular recess, the connecting element 5, the first PCB plate 6, the pressure-resettable electronic microswitch 7, the ring encoder 8, the connecting seat 9, the rotary handle 2, the keypad 10, the push rod 11 and the screen 4 provides a novel structure of the electronic handle for faucets, which has the following advantageous effects: (1) Multifunctional integration: Through rotary and push operation, users can perform various function switching or parameter adjustments, thereby reducing unnecessary switch buttons and making the device surface more compact and increasing practicality (for example, when applied to a smart kitchen faucet: the screen 4 displays the current functions or parameters, allowing users to intuitively understand and precisely adjust the operating status of the device);(2) High ease of use and good user experience: Users can intuitively view the relevant information on the screen 4 and easily operate it in combination with the rotary handle 2 and the keypad 10, thereby lowering the barrier to use and improving the accuracy and convenience of operation; (3) Easy assembly and maintenance: Firstly, the present utility model can be processed into a product with standardized interfaces and dimensions that can be directly plugged into or mounted into devices, thus simplifying the assembly process and reducing assembly costs; secondly, the electronic handle has a modular design so that users can easily replace or repair the relevant components in the event of a malfunction, thereby reducing maintenance effort and costs;(4) Advantage in terms of value for money: Due to the integrated and modular design of the electronic handle, both the costs for developing molds and the costs for unnecessary buttons are reduced for device manufacturers, which strengthens competitiveness and can meet the needs and preferences of different users.

[0072] In another technical solution, the connecting seat 9 comprises a first tube 901 and a second tube 902, which are coaxially connected. The end of the first tube 901 furthest from the second tube 902 projects into the circular recess, and a first sealing ring 12 is arranged on the immersed end of the first tube 901 – the outer circumferential wall of the first sealing ring 12 rests tightly against the inner wall of the circular recess. The outer circumferential wall of the second tube 902 is snap-fitted to the inner circumferential wall of the rotary handle 2, and the inner circumferential wall of the second tube 902 is snap-fitted to the rotor of the ring encoder 8.

[0073] In the above technical solution, the first tube 901 and the second tube 902 are formed in one piece to ensure their coaxiality. The end of the first tube 901 furthest from the second tube 902 projects into the circular recess, and an annular groove is formed on the tube body of the immersed end in which the first sealing ring 12 is arranged. The first sealing ring 12 rests tightly against the inner wall of the housing 1, thereby ensuring a rotatable sealing connection between the connecting seat 9 and the housing 1, which prevents the ingress of external water or water vapor into the housing 1 and thus prevents damage to the internal components.

[0074] Second locking structures are formed on the inner circumferential wall of the second tube 902, and second locking grooves are machined on the outer circumferential wall of the rotor of the ring encoder 8, which are aligned with the second locking structures – thus creating a locking connection between the second tube 902 and the rotor of the ring encoder 8. To improve the connection reliability, the second locking structures and the second locking grooves are preferably multiple.

[0075] In this technical solution, the assembly process proceeds as follows: First, the first PCB plate 6, on which the ring encoder 8 and the pressure-resettable electronic microswitch 7 are welded, is placed in the housing 1; then, the first sealing ring 12 is mounted on the first tube 901, the second locking structures are aligned with the corresponding second locking grooves, the connecting seat 9 is connected to the rotor of the ring encoder 8 via the locking connection, and simultaneously, the first tube 901 of the connecting seat 9 is inserted into the circular recess of the housing 1; subsequently, the first locking structures are aligned with the corresponding first locking grooves, and the rotary handle 2 is mounted on the connecting seat 9 via the locking connection.During use, the external force drives the rotary handle 2 to rotate, which in turn drives the second tube 902. The second tube 902 then drives the rotor of the ring encoder 8 to rotate, while the first tube 901 rotates against the inner wall of the circular recess. This technical solution allows for easy assembly and disassembly; in addition, the connection exhibits high stability and excellent transmission efficiency.

[0076] In another technical solution, the housing 1 is made of semi-transparent black material; the electronic handle further comprises a pair of mounting plates 14, which are arranged at a distance and coaxially at the end of the housing 1 closest to the faucet body, with the first PCB plate 6 being detachably attached to the mounting plate 14 furthest from the faucet body. A support plate 15 is connected between the pair of mounting plates 14, and the screen 4 is mounted on the support plate 15.

[0077] In the above technical solution, the housing 1 is made of semi-transparent black polycarbonate (PC). Polycarbonate has good mechanical properties, optical properties, and weather resistance – the semi-transparent black appearance not only meets aesthetic requirements but can also conceal the internal structure to a certain extent without blocking the light emitted by the screen 4.

[0078] The pair of mounting plates 14 in the housing 1 are arranged coaxially with the housing 1 and are circular in shape, with their diameter being slightly smaller than the inner diameter of the housing 1 to ensure coaxial mounting within the housing 1. The first PCB plate 6 is mounted on the side wall of the mounting plate 14 closest to the open end of the housing 1 (specifically, by screwing it in place). A support plate 15 is connected between the pair of mounting plates 14, with both ends of the support plate 15 firmly attached to the mounting plates 14. The support plate 15 is positioned eccentrically to the mounting plates 14, and the screen 4 is mounted on its side wall facing the housing 1.For practical use, an OLED screen 4 with a suitable size and resolution is selected for screen 4, whose brightness and contrast ratio should meet the requirements for a clear display under different ambient light conditions.

[0079] In this technical solution, the entire device must be tested before official use, and the testing procedure is as follows: First, the power supply is connected to check that screen 4 illuminates normally and that the displayed content is clear and accurate; then, the visibility of screen 4 is tested under different ambient light intensities, and if necessary, the brightness and contrast settings of screen 4 are adjusted to ensure that the user can clearly read the information on screen 4 under all usage conditions. Finally, the rotary handle 2 is manually turned to check that the ring encoder 8 accurately outputs the signals for function switching or parameter adjustment and that these are correctly displayed on screen 4.The device may only be put into operation after successful testing, and any deviations occurring during the test must be rectified promptly. With this technical solution, the arrangement of the housing 1 made of semi-transparent black material and the support plate 15 used for mounting the screen 4 protects the screen 4 inside the housing 1, thereby preventing interference from the external environment and further increasing the service life of the screen 4.

[0080] In another technical solution, a cup-shaped key cover 16 is arranged coaxially at the end of the pushrod 11 furthest from the first PCB plate 6. The opening of the key cover 16 faces the ring encoder 8, and the opposite end of the key cover 16 is connected to the key plate 10 via adhesive tape. Specifically, the key cover 16 is cylindrical-cup shaped, with its opening facing the first PCB plate 6. The end of the pushrod 11 furthest from the first PCB plate 6 is coaxially and rigidly connected to the base of the key cover 16, and the outer wall of the base of the key cover 16 is connected to the key plate 10 via adhesive tape.For practical purposes, to reduce the horizontal volume of the entire device, an annular receiving chamber 903 can be formed on the side wall of the second tube 902, which faces the key cover 16. The opening end of the key cover 16 is inserted into this chamber to prevent any obstruction of its movement. This design of the key cover 16 achieves two advantages: firstly, its contact area is larger than that of the push rod 11, resulting in a more stable adhesive bond with the key plate 10; and secondly, the arrangement of the push rod 11 on the key cover 16 simplifies manufacturing. In practical applications, the push rod 11 and the key cover 16 are preferably formed as a single piece.

[0081] In another technical solution, a second sealing ring 13 is arranged on the outer circumferential wall of the keypad cover 16. This second sealing ring is located on the side of the second tube 902 furthest from the first tube 901. The outer circumferential wall of the second sealing ring 13 rests tightly against the inner circumferential wall of the rotary handle 2. Specifically, an annular groove is formed on the outer circumferential wall of the keypad cover 16, in which the second sealing ring 13 is arranged. The second sealing ring 13 rests tightly against the inner circumferential wall of the rotary handle 2. This technical solution, through the arrangement of the second sealing ring 13, prevents water from penetrating the interior of the rotary handle 2 and the housing 1 through the gap between the keypad cover 16 and the rotary handle 2, thus protecting the internal electronic components (such as the first PCB 6, the ring encoder 8, the pressure-resettable electronic microswitch 7, etc.).This prevents short circuits and damage due to water ingress, extends the service life of the entire structure of the electronic handle and ensures its reliable operation in the humid environment of the kitchen.

[0082] In another technical solution, a horizontal plate 17 is connected transversely between the pair of mounting plates 14, on which a pair of storage shelves 18 are formed. A second PCB plate 19 for mounting function lights rests on the pair of storage shelves 18. The electronic handle also includes an auxiliary support 20, which is arranged on the horizontal plate 17. Several function light mounting holes 21 are formed on the auxiliary support 20, located above the second PCB plate 19. Several function symbols are provided on the outer wall of the housing 1, which correspond to the multiple function light mounting holes 21.

[0083] Specifically, a horizontal plate 17 is arranged between the pair of mounting plates 14, with both ends of the plate connected to the pair of mounting plates 14. A pair of support shelves 18 are formed on the horizontal plate 17, on which the second PCB plate 19 is mounted. This second PCB plate 19 serves to mount function lights, which are welded to it. The function symbols on the housing 1 can be applied by molding or laser printing and can be designed as symbols for different functions (such as a symbol for pure water at room temperature, a symbol for hot water, an on / off symbol, etc.), depending on practical requirements. When the function lights illuminate, the user can clearly see the current status of the faucet.The auxiliary support 20 comprises a pair of supports and a support body arranged on the pair of supports, the pair of supports being arranged on both sides of the pair of storage shelves 18. The multiple function light mounting holes 21 on the support body are located above the second PCB plate 19, and the function symbols on the housing 1 correspond to the function light mounting holes 21. After several function lights are welded onto the second PCB plate 19, they are inserted or positioned in the corresponding function light mounting holes 21, with the illuminated ends of the function lights being close to the corresponding function symbols so that the user can see them intuitively.

[0084] This technical solution, through the arrangement of the horizontal plate 17, the storage shelves 18, the second PCB plate 19, the auxiliary support 20, the functional light mounting holes 21, and the function symbols, provides a way for the user to intuitively perceive the current state of the faucet. The design of the auxiliary support 20 and the functional light mounting holes 21 allows the functional lights to be fixed in the mounting holes 21, ensuring precise alignment between the functional lights and their corresponding function symbols. This prevents the functional lights from shifting due to external forces or factors without fixation, which would lead to an incorrect alignment between the functional lights and their symbols.

[0085] In another technical solution, the pushrod is snap-fitted to the inner wall of the ring encoder 8, such that the end of the pushrod closest to the first PCB plate 6 slides along the inner wall of the ring encoder 8. Specifically, several slotted grooves are machined on the surface of the end of the pushrod 11 facing the first PCB plate 6. Several projections are machined on the inner wall of the stator 801, which is arranged coaxially in the rotor 802 of the ring encoder 8, and these projections are aligned with the slotted grooves (the projections form the snap-fit ​​structure), with the projections being inserted into the corresponding slotted grooves. When the keypad 10 is pressed by an external force and the pushrod 11 is driven into motion, the pushrod 11 slides along the projections to precisely depress the pressure-resettable electronic microswitch 7. For practical applications, the number of slotted grooves and projections is preferably multiple (e.g.,four), whereby the design with multiple slots and projections can further improve the accuracy of the movement of the push rod 11.

[0086] In another technical solution, keypad 10 features a CD-patterned decorative cover. The design of this cover improves grip comfort, providing a pleasant and comfortable feel during operation and enhancing the user experience. Furthermore, it is characterized by ease of manufacture, abrasion resistance, and an aesthetically pleasing appearance.

[0087] In another technical solution, a polyimide insulating layer is arranged on the inner wall of the functional light mounting hole, and LED lights are welded onto the second PCB plate. The functional symbols are formed into groove structures by laser engraving, and these groove structures are filled with luminescent ink.

[0088] In the above technical solution, the production of the polyimide insulating layer on the inner wall of the functional light mounting hole is carried out as follows: First, the inner wall is sandblasted, then a polyimide insulating layer with a thickness of 50 ± 5 µm is sprayed on.

[0089] SMD2835 LEDs can be selected as LED light sources for the second PCB board. These LEDs are soldered onto the second PCB board using SMD mounting and connected to the main control PCB (main control board) via a 0.5 mm spacing FPC ribbon cable. The response time is ≤80 ms, ensuring a fast response speed.

[0090] The functional symbols are formed into fine grooves by laser engraving (line width 0.3 mm, depth 0.2 mm), which are then filled with luminescent ink (e.g., LUXE 3801). This creates an area with a light transmission of 60–70%, which, together with the LED light sources, forms a brightness contrast ratio of 2:1. In this way, the user can clearly see the symbols even in the dark, and the contrast ratio with the light from the LEDs provides an aesthetically pleasing visual experience.

[0091] The logic for controlling the light of the LED lights via the second PCB board is as follows: - when the rotary control unit switches the water outlet mode, the LED light in the area of ​​the corresponding function symbol illuminates continuously at 100% brightness, i.e. the light of the corresponding function symbol remains permanently on so that the user can easily recognize the currently activated function mode; - Pressing the button for 2 seconds can trigger a cyclical brightness control. The three PWM parameter levels are as follows: Level 1 (low brightness): Frequency 200 Hz, Duty cycle 30%; Level 2 (medium brightness): Frequency 500 Hz, Duty cycle 60%; Level 3 (high brightness): Frequency 1 kHz, Duty cycle 100%.

[0092] The aforementioned technical solution improves the insulating properties and durability by spraying on a polyimide insulating layer (50 ± 5 µm thick). The use of SMD2835 LEDs, connected to the main control PCB via a 0.5 mm spacing FPC flat cable and exhibiting a response time of ≤ 80 ms, ensures the speed and accuracy of the light control. The functional symbols are laser-engraved into groove structures with a line width of 0.3 mm and a depth of 0.2 mm and filled with LUXE 3801 luminescent ink, creating an area with a light transmittance of 60%–70%. This, together with the LEDs, provides a brightness contrast ratio of 2:1, thus improving the visibility and aesthetics of the symbols even in darkness.PWM dimming technology enables multi-stage brightness control of the light, which is both energy-saving and enhances the user experience. Furthermore, the lighting control logic is closely integrated with user controls, providing intuitive visual feedback and thereby increasing the product's interactivity and ease of use. Overall, the highly precise and fast-responding LED lighting control, combined with the intelligent logic, improves the product's visibility, aesthetics, and user experience while simultaneously achieving energy savings.
