[0001] This utility model relates to the field of water purification equipment control technology, specifically to a push-button knob and a water purifier faucet. Background Technology

[0002] Traditional water purifier faucets typically use simple knobs or buttons to adjust basic parameters such as water temperature and flow. This operating mode is not only monotonous and lacks an intuitive visual feedback mechanism, making it difficult for users to obtain real-time status information during operation, but the internal structure of the knobs or buttons is also relatively simple and lacks integration, often leading to many inconveniences during equipment maintenance or repair. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned defects or problems in the background technology and provide a push-button knob and a water purifier faucet. This push-button knob has a high degree of integration, combines intuitive visual feedback and easy maintenance, and meets the needs of users.

[0004] To achieve the above objectives, the various embodiments of this utility model adopt the following technical solutions, but are not limited to the following solutions:

[0005] The first technical solution relates to a push-button knob, including a base with an opening opposite to the pressing direction; a base connected to the base in the pressing direction that is pressable and non-rotating, and having a mounting groove with an opening opposite to the pressing direction; a light guide on the base; a knob rotatably connected to the base and limited relative to the base in the pressing direction, and having several magnets that move synchronously with the knob's rotation; the light guide located near the bottom periphery of the knob's outer wall; and a circuit board fixed in the mounting groove of the base, which integrates a button element, a light element, and several Hall effect sensors evenly distributed circumferentially. The Hall effect sensors cooperate with the magnets to form a sensing area to detect the function selection when the knob is rotated. When the knob is rotated to a preset function position, the light emitted by the light element forms different colored light rings around the knob through the light guide, with different function positions corresponding to the display colors of the light rings. When the knob is pressed, the base abuts against the base, triggering the button element to select the corresponding function position.

[0006] The second technical solution is based on the first technical solution, which includes an elastic element installed between the base and the seat body. The elastic element acts on the base so that the knob returns to its initial position after being pressed and released.

[0007] The third technical solution is based on the first technical solution, wherein the number of magnets is two, which are symmetrically distributed at 180 degrees along the circumference of the knob.

[0008] The fourth technical solution is based on the second technical solution. In this solution, a boss is provided on the side of the base facing the opening. The bottom of the mounting groove of the base is provided with a through hole facing the boss. The through hole is covered with a button cap and the button cap abuts against the boss. The circuit board abuts against the button cap. When the knob is pressed, the boss transmits the pressing force to the button element through the button cap to trigger the button element.

[0009] The fifth technical solution is based on the fourth technical solution, wherein the button cap is made of waterproof silicone material and is fixedly connected to the base through a secondary encapsulation process.

The housing and the cover are fixedly connected to each other to prevent rotation. The cover is located in the mounting groove and is rotatably connected to the base. It also has a limiting fit with the base in the pressing direction. A magnet is installed on the cover. The cover has a gear slot with an opening facing the bottom of the housing groove and located in the mounting groove. Several spring pins are engaged in the gear slot. The inner wall of the base has several gear grooves that cooperate with the spring pins. The spring pins pass through the gear slots and abut against the inner wall of the base. When the knob is rotated, the spring pins deform. When rotated to the preset gear, the spring pins abut against the bottom of the gear groove to achieve gear positioning and tactile feedback.

[0011] The seventh technical solution is based on the sixth technical solution, wherein the base is provided with an annular groove around its periphery, the cover is placed on the base and is provided with buckles that are adapted to the annular groove along the circumferential direction, and the buckles are engaged in the groove to prevent the cover from detaching from the base in the opposite direction of pressing.

[0012] The eighth technical solution is based on the fourth technical solution, wherein the base is provided with a limiting part that protrudes radially from its outer peripheral surface, the limiting part is provided with a stepped limiting surface that adapts to the outer shell and the cover to limit the movement of the outer shell and the cover relative to the base in the pressing direction; the limiting part is provided on the opening of the seat body and there is a clearance gap between the limiting part and the seat body to allow a pressable connection to be formed between the base and the seat body.

[0013] The ninth technical solution is based on the eighth technical solution. In this solution, the base is made of light-transmitting plastic material, and the limiting part and the groove wall of the mounting groove form a light guide part. The light emitted by the light element is diffusely reflected by the cover covering the bottom surface of the mounting groove, and passes through the groove wall of the mounting groove and is obliquely led out along the gap of the limiting part to form a light ring in the circumference of the knob side wall.

[0014] The tenth technical solution is based on the second technical solution, wherein the base and the seat body are connected by a first screw, the connection positions are evenly distributed along the circumference of the seat body, and the elastic element is sleeved on the first screw.

[0015] The eleventh technical solution is based on any one of the first to tenth technical solutions, wherein a water purifier faucet includes a panel assembly; the panel assembly includes a display panel, a main board and the aforementioned push knob; the display panel extends along a direction perpendicular to the pressing direction, and the push knob is located at one end of the display panel.

[0016] The twelfth technical solution is based on the eleventh technical solution. In this solution, the display panel is equipped with function indicators that cooperate with the light ring display, a temperature indicator for the real-time temperature of the water from the faucet, a child lock button, a temperature adjustment button, a water replenishment button, and a filter replacement indicator.

[0018] As can be seen from the above description of the various embodiments of the present utility model, compared with the prior art, the various embodiments of the present utility model have the following beneficial effects:

[0019] In the first technical solution and related embodiments, the push-button knob integrates both rotation and pressing operation modes. Rotation of the knob allows selection of different function levels. Several Hall effect sensors evenly distributed circumferentially, in conjunction with radially symmetrically arranged magnets, detect the knob's rotational position, thus enabling function level selection and improving the sensitivity of function level switching. When the knob is rotated to a preset function level, the light element forms different colored light rings circumferentially through the light guide structure on the knob's side wall, providing the user with intuitive visual feedback and clearly indicating the currently selected function level. Furthermore, pressing the knob activates the button element, thereby controlling the call to the selected function level. Overall, the push-button knob is convenient to operate, provides intuitive feedback, and enhances the user experience. The circuit board integrates button elements, light elements, and Hall effect sensors, achieving a high degree of integration, simplifying the wiring process, reducing the number of wires, facilitating subsequent sealing and potting processes, meeting more stringent waterproof requirements, and further broadening its application scenarios and scope of application.

[0020] In the second technical solution and related embodiments, the built-in elastic element ensures that the knob can quickly and stably return to the initial position after being pressed, making it convenient for the user to perform the next operation.

[0021] In the third technical solution and related embodiments, a sensing area is formed by a pair of magnets distributed at 180 degrees and multiple groups of Hall elements evenly arranged on the PCB, which facilitates the selection and recall of functions, reduces costs, and improves the sensitivity (angle) of function switching.

[0022] In the fourth technical solution and related embodiments, the push-button knob achieves an efficient pressing force transmission mechanism through the cooperation of a boss on the base with a corresponding through hole and button cap on the base. When the user presses the knob, the button cap first contacts the boss and directly transmits the pressing force to the button element on the circuit board, activating the selected function. This design simplifies the structural complexity of the pressing operation, ensures the stability and accuracy of the pressing force, and improves the knob's response speed.

[0023] In the fifth technical solution and related embodiments, the waterproof silicone material possesses excellent waterproof and moisture-proof properties, effectively isolating moisture and humidity from corroding the internal electronic components of the knob, thus improving the knob's waterproof rating and lifespan. Simultaneously, the silicone material also exhibits good elasticity and wear resistance, ensuring the button cap maintains a good feel and durability during prolonged use. Furthermore, the application of a secondary overmolding process further enhances the stability and reliability of the connection between the button cap and the base. This process, through injection molding or bonding, firmly fixes the button cap to the base, effectively preventing loosening or detachment due to long-term use or external impact.

[0024] In the sixth technical solution and related embodiments, the outer shell and the cover are fixedly connected by an anti-rotation method to ensure the stability of the connection between the outer shell and the cover during the rotation of the knob, preventing displacement of the two. Simultaneously, the cover and the base are rotatably connected, allowing the knob to switch between different function levels. Only the combination of the outer shell and the cover rotates, making it easier to adjust the knob's rotation feel and avoiding the influence of various factors on the knob's feel. The cover is positioned relative to the base in the pressing direction to ensure the stability of the knob during rotation and pressing. When the knob is rotated to the preset level, the spring pin will abut against the bottom of the level groove, achieving level positioning and tactile feedback, improving the ease of operation of the knob, and allowing the user to intuitively feel the change in the currently selected function level.

[0025] In the seventh technical solution and related embodiments, a stable and reliable connection between the cover and the base is achieved through the annular groove around the base and the matching buckle design on the cover, resulting in higher efficiency and structural stability. This buckle and groove matching method also facilitates the assembly and disassembly of the knob, making maintenance easy.

[0026] In the eighth technical solution and related embodiments, the limiting part on the base achieves the limiting of the outer shell and the cover in the pressing direction. The limiting part protrudes radially from the outer peripheral surface of the base, and the limiting surface has a stepped structure to adapt to the shape of the outer shell and the cover, ensuring that they can be stably maintained in the preset position during the pressing process without accidental displacement. The clearance design between the limiting surface and the base body allows relative movement between the base and the base body, making the pressing process smooth and unobstructed.

[0027] In the ninth technical solution and related embodiments, in traditional designs, the lighting elements typically employ a top-emitting method. This method often leads to problems such as spotting and uneven light emission in the halo. To solve these problems, a large number of lighting elements are often required, which not only increases costs but also enhances the complexity of production and installation. However, this design utilizes a base made of translucent plastic material. The light emitted by the lighting elements undergoes primary diffuse reflection and scattering, passing through the mounting groove wall and obliquely through the gap along the limiting surface, ultimately forming a uniform light ring around the circumference of the knob's side wall. This side-emitting method makes the light softer and more uniform, avoiding the halo spotting and uneven light emission problems of traditional top-emitting methods, reducing the number of LEDs, and lowering costs.

[0028] In the tenth technical solution and related embodiments, the push-button knob is connected to the base and seat body by a first screw, achieving a stable structural connection. An elastic element fitted onto the first screw provides stable support and a good tactile feel for the button. The first screw connections are evenly distributed circumferentially, ensuring the button's balance and stability during pressing. This first screw connection method facilitates maintenance and replacement, effectively reducing after-sales costs.

[0029] In the eleventh technical solution and related embodiments, the water purifier faucet integrates multiple functions into one unit, achieving an efficient, convenient, and intelligent water purification experience through a panel assembly, body assembly, water channel assembly, and pipe fittings. The push-button knob in the panel assembly provides a stable and tactile operating experience, and its light ring display, in conjunction with the function level indicators on the display panel, intuitively shows the current working status of the faucet.

[0030] In the twelfth technical solution and related embodiments, the display panel is also equipped with a temperature indicator, which can display the temperature of the water coming out of the faucet in real time, providing users with accurate temperature information so that users can adjust the water temperature as needed. In addition, the inclusion of a child lock button, a temperature adjustment button, a water refill button, and a filter replacement indicator further enriches the functionality of the faucet and improves the safety and convenience of use.

[0031] In the thirteenth technical solution and related embodiments, the snap-fit ​​and water-sealed connection between the panel assembly and the body assembly ensures the electrical safety of the mainboard. The snap-fit ​​fixing of the water channel assembly and the body assembly simplifies the installation process and improves the stability and reliability of the structure. The anti-rotation connection between the pin fittings and the body assembly, as well as the use of anti-loosening nuts, effectively prevents the pin fittings from loosening during long-term use, improving the stability and durability of the faucet structure.

[0046] In the claims, description and accompanying drawings of this utility model, the terms "comprising", "having", and variations thereof are used to mean "including but not limited to".

[0047] See Figures 1 to 7 ,like Figure 1 As shown, a push-button knob includes a base 7, a base 6, a knob 5, a circuit board 8, and an elastic element 9.

[0048] Seat 7, such as Figure 1 and Figure 2As shown, it has a structure with an opening opposite to the pressing direction for accommodating and securing other components of the pressing knob. The base 7 is preferably made of plastic or metal to ensure its strength and durability. The opening of the base 7 is designed with a structure that mates with the base 6 to ensure a tight connection and transmission of pressing force during pressing. A boss 71 is provided on the side of the base 7 facing the opening, and the boss 71 is located in the middle of the base 7.

[0049] Base 6, such as Figure 1 , Figure 2 and Figure 4 As shown, the base 6 is made of translucent plastic and has a mounting groove 61 with an opening opposite to the pressing direction for mounting internal components such as the circuit board 8. The base 6 and the seat 7 are connected by a pressable and anti-rotation mechanism, ensuring that the base 6 will not rotate when the knob 5 is rotated. The base 6 and the seat 7 are connected by a first screw 72, achieving a stable structural connection. The connection positions of the first screw 72 are evenly distributed around the circumference of the seat 7, ensuring the balance and stability of the pressing knob during the pressing process. The first screw 72 connection method facilitates maintenance and replacement, effectively reducing after-sales costs.

[0050] The base 6 also has a limiting structure that cooperates with the knob 5 to limit the movement distance of the knob 5 in the pressing direction. For example... Figure 4 As shown, the inner wall of the base 6 is provided with several stop grooves 64, and the base 6 has a limiting part 66 that protrudes radially from its outer peripheral surface. The limiting part 66 has a stepped limiting surface 67 to accommodate the knob 5. The limiting part 66 covers the opening of the seat body 7 and has a clearance gap 73 between it and the seat body 7 to allow a pressable connection between the base 6 and the seat body 7. The clearance gap 73 between the limiting surface 67 and the seat body 7 is designed to allow relative movement between the base 6 and the seat body 7, making the pressing process smooth and unobstructed.

[0051] like Figure 2 and Figure 5 As shown, the base 6 is provided with a light guide. When the knob 5 is rotated to a preset function position, the light emitted by the light element forms different colored light rings 56 around the knob 5 through the light guide. Different function positions correspond to the display colors of the light rings 56. Specifically, the limiting part 66 and the groove wall of the mounting groove 61 form a light guide. The light emitted by the light element is diffusely reflected by the cover 52 covering the bottom surface of the mounting groove 61, and passes through the groove wall of the mounting groove 61. It is then led out along the limiting part 66 obliquely towards the light path 60 and the clearance gap 73, forming a light ring 56 around the side wall of the knob 5.

[0052] The light emitted by the lighting element passes through the wall of the mounting groove 61 and is diagonally guided through the clearance gap 73 along the limiting part 66, forming a light ring 56 around the side wall of the knob 5. The design of the light guide allows the light to be evenly distributed around the knob 5, creating a clear and eye-catching indication effect. In traditional designs, the lighting element usually adopts a top-emitting method, which often leads to problems such as spotting and uneven light emission in the halo. To solve these problems, a large number of lighting elements are often required, which not only increases costs but also increases the complexity of production and installation. This design uses a base 6 made of light-transmitting plastic material, and combines the light emitted by the lighting element with diffuse reflection and scattering of the light by the cover 52 covering the bottom surface of the mounting groove 61. The light then passes through the wall of the mounting groove 61 and diagonally through the clearance gap 73 along the limiting part 66, ultimately forming a uniform light ring 56 around the side wall of the knob 5. This side-emitting method makes the light softer and more uniform, avoiding the halo spotting and uneven light emission problems caused by traditional top-emitting methods, reducing the number of LEDs, and lowering costs.

[0053] The mounting groove 61 has a through hole 62 at its bottom, directly opposite the boss 71. A button cap 63 is placed over the through hole 62, and the button cap 63 abuts against the boss 71. When the knob is pressed, the boss 71 transmits the pressing force through the button cap 63. Specifically, the button cap 63 is made of waterproof silicone and is fixedly connected to the base 6 using a secondary encapsulation process. The waterproof silicone material has excellent waterproof and moisture-proof properties, effectively isolating moisture and humidity from corroding the internal electronic components of the knob 5, thus improving the waterproof rating and lifespan of the knob 5. Simultaneously, the silicone material also has good elasticity and wear resistance, ensuring that the button cap 63 maintains a good feel and durability during prolonged use. Furthermore, the application of the secondary encapsulation process further enhances the stability and reliability of the connection between the button cap 63 and the base 6. This process, through injection molding or bonding, firmly fixes the button cap 63 to the base 6, effectively preventing loosening or detachment due to long-term use or external impact.

[0054] Knob 5, as Figure 1 and Figure 2 As shown, it is the main component operated by the user. It is rotatably connected to the base 6 and is positioned relative to the base 6 in the pressing direction. Several magnets 54 are symmetrically arranged radially. When the knob 5 is rotated, it drives the magnets 54 mounted on it to rotate synchronously.

[0055] The knob 5 comprises two parts: a housing 51 and a cover 52. The housing 51 has an opening in the pressing direction and fits onto the cover 52. The housing 51 and the cover 52 are connected by an anti-rotation fixing mechanism to ensure that they will not separate during rotation. Specifically, the housing 51 has an opening groove facing the pressing direction, and the cover 52 is fitted onto the bottom of the opening groove. The cover 52 has corresponding latches and slots to limit its movement during rotation. At the same time, the housing 51 and the cover 52 are fixed together by screws to ensure a secure connection between them.

[0056] Cover 52, such as Figures 1 to 3 As shown, the cover 52 has an opening along the pressing direction, suitable for covering the mounting groove 61 of the base 6, and forms a rotatable connection with the base 6, while also being positioned and engaged with the base 6 in the pressing direction. Specifically, the base 6 has an annular groove 65 around its periphery, and the cover 52 is placed on the base 6 and has a buckle 55 along its periphery that matches the annular groove 65. The buckle 55 engages in the groove to prevent the cover 52 from detaching from the base 6 in the direction opposite to the pressing direction. Through the design of the annular groove 65 around the base 6 and the buckle 55 that matches the cover 52, a stable and reliable connection between the cover 52 and the base 6 is achieved, resulting in higher efficiency and structural stability. This engagement method of the buckle 55 and the groove also facilitates the assembly and disassembly of the knob 5, making maintenance easier.

[0057] The stepped limiting surface 67 of the limiting portion 66 of the base 6 is adapted to the outer shell 51 and the cover 52 to limit the movement of the outer shell 51 and the cover 52 relative to the base 6 in the pressing direction. Specifically, the limiting portion 66 protrudes radially from the outer peripheral surface of the base 6, and the limiting surface 67 has a stepped structure facing away from the pressing direction toward the outer shell 51 and the cover 52 and adapts to the shape of the outer shell 51 and the cover 52, ensuring that the outer shell 51 and the cover 52 can abut against the limiting surface 67 during the pressing process and that no accidental displacement occurs. The limiting portion 66 on the base 6 achieves the limiting of the outer shell 51 and the cover 52 in the pressing direction.

[0058] Magnets 54 are mounted on knob 5 and arranged symmetrically radially. Specifically, there are two magnets 54, symmetrically distributed 180 degrees circumferentially. In this embodiment, magnets 54 are mounted on cover 52. Figure 2 and Figure 3 As shown, the cover 52 has a stop groove 59 with an opening facing the bottom of the outer shell 51 and located in the mounting groove 61. The stop groove 59 has a pair of mounting holes 57 symmetrically arranged radially at 180 degrees for mounting a pair of magnets 54. When the outer shell 51 is rotated, it drives the cover 52 to rotate, and the magnets 54 move synchronously.

[0059] The cover 52 is also provided with several radially protruding spring pins 53. Specifically, several spring pins 53 are engaged in the gear position groove 59. The spring pins 53 pass through the gear position groove 59 and abut against the inner wall of the base 6. The inner wall of the gear position groove 59 is provided with a side hole 58, which faces the mounting groove 61 of the base 6. The spring pins 53 are in a semi-open U-shape, with both sides of the U-shape engaged in the gear position groove 59. The bottom of the U-shape extends out of the side hole 58 and cooperates with the gear position groove 64 of the base 6 for gear positioning. When the knob 5 is rotated, the spring pins 53 deform; when rotated to the preset gear position, the spring pins 53 abut against the bottom of the gear position groove 64 to achieve gear positioning and tactile feedback. Specifically, there are two spring pins 53.

[0060] In this embodiment, the outer shell 51 and the cover 52 are fixedly connected by an anti-rotation method to ensure the stability of the connection between the outer shell 51 and the cover 52 during the rotation of the knob 5, preventing displacement of the two. Simultaneously, the cover 52 and the base 6 are rotatably connected, allowing the knob 5 to switch between different function levels. Only the combination of the outer shell 51 and the cover 52 rotates, making it easier to adjust the feel of the knob 5 and avoiding the influence of various factors on the feel of the knob 5. The cover 52 is positioned relative to the base 6 in the pressing direction to ensure the stability of the knob 5 during rotation and pressing. When the knob 5 is rotated to the preset level, the spring pin 53 abuts against the bottom of the level groove 64, achieving level positioning and tactile feedback, improving the ease of operation of the knob 5, and allowing the user to intuitively feel the change in the currently selected function level.

[0061] Circuit board 8, such as Figure 1 As shown, it is fixed in the mounting groove 61 of the base 6 and abuts against the button cap 63. The circuit board 8 integrates button elements, lighting elements, and several Hall effect sensors evenly arranged circumferentially. Specifically, the circuit board 8 is a PCB printed circuit board 8.

[0062] A Hall effect sensor, in conjunction with a magnet 54 on knob 5, forms a sensing area to detect the function selection when knob 5 is rotated. When the knob is in its initial position, the magnet 54 on the knob has a specific magnetic field distribution relative to the Hall effect sensor. At this time, the Hall effect sensor outputs a corresponding initial electrical signal based on the strength and direction of the magnetic field. This electrical signal represents an initial function level or state. When the user rotates knob 5, the magnet 54 on knob 5 rotates accordingly. Because the position and direction of the magnet 54 change, the distribution of the magnetic field also changes accordingly. The Hall effect sensor senses this change in the magnetic field in real time and converts it into a change in electrical signal. Circuit board 8 collects and analyzes the electrical signal output by the Hall effect sensor. Through a pre-set algorithm and threshold, the system can accurately identify the current position of knob 5, thereby determining the corresponding function level.

[0063] Circuit board 8 is connected to an external power supply and controller via wires or other means to enable signal transmission and control.

[0064] In this embodiment, a pair of magnets symmetrically distributed at 180 degrees and multiple sets of Hall elements evenly arranged on the PCB (printed circuit board) are used to form the sensing area. This design facilitates the selection and recall of different functions according to needs, helps reduce costs, and improves the sensitivity of function switching (especially the response speed of angle switching).

[0065] The button element abuts against the button cap 63. When the knob is pressed, the boss 71 transmits the pressing force to the button element through the button cap 63 to activate the button element. The efficient pressing force transmission mechanism is achieved through the cooperation between the boss 71 on the base 7, the corresponding through hole 62 on the base 6, and the button cap 63. When the user presses the knob, the button cap 63 first contacts the boss 71 and directly transmits the pressing force to the button element on the circuit board 8, activating the selected function. This design simplifies the structural complexity of the pressing operation, ensures the stability and accuracy of the pressing force, and improves the response speed of the knob 5.

[0066] Elastic element 9, such as Figure 1 and Figure 2 As shown, it is installed between the base 6 and the seat 7 to provide elastic feedback when the knob is pressed and to return the knob 5 to its initial position after the press is released. The elastic element 9 is preferably made of spring or elastic rubber to ensure its elasticity and durability. In this embodiment, the elastic element 9 is a spring, which is sleeved on the first screw 72. The connection positions of the first screw 72 are evenly distributed along the circumference of the seat 7. The elastic element 9 sleeved on the first screw 72 provides stable support and good tactile feedback for the button.

[0067] When the knob is pressed, the base 7 presses against the base 6, the button element is activated to control the selection of function levels, and the elastic element 9 acts on the base 6 so that the knob 5 returns to its initial position after being pressed and released.

[0068] In this embodiment, the push-button knob integrates both rotation and pressing operation modes. Rotating the knob 5 allows selection of different function levels. Several Hall effect sensors evenly distributed circumferentially, in conjunction with radially symmetrically arranged magnets 54, detect the rotational position of the knob 5, enabling function level selection and improving the sensitivity of function level switching. When the knob 5 is rotated to a preset function level, the light element forms different colored light rings 56 circumferentially through the light guide structure on the side wall of the knob 5, providing the user with intuitive visual feedback and clearly indicating the currently selected function level. Furthermore, pressing the knob activates the button element, thereby controlling the recall of the selected function level. The built-in elastic element 9 ensures that the knob 5 quickly and stably returns to its initial position after being pressed, facilitating the user's next operation. Overall, this push-button knob is convenient to operate, provides intuitive feedback, and enhances the user experience. The circuit board integrates button components, lighting components, and Hall effect sensor components. The high degree of integration simplifies the wiring process, reduces the number of wires, facilitates subsequent sealing and potting processes, meets more stringent waterproof requirements, and further broadens its application scenarios and scope of application.

[0069] A type of water purifier faucet, such as Figure 1 , Figures 5 to 7 As shown, it includes a panel assembly 1, a body assembly 2, a water channel assembly 3, and a pin fitting 4.

[0070] Panel component 1, such as Figure 1 As shown, the system includes a display panel 10, a main board 13, and the aforementioned push-button knob. The display panel 10 extends perpendicular to the pressing direction, and the push-button knob is located at one end of the display panel 10. Specifically, the base 7 is located at one end of the display panel 10 and is integrally formed with the display panel 10. The main board 13 is installed between the display panel 10 and the body assembly 2. Specifically, the display panel 10 and the body assembly 2 are fixed together by screws. The main board 13 is a PCB hard-brush circuit board 8. A light-transmitting PET film 11 and a light-blocking plate 12 are also installed between the main board 13 and the display panel 10. The light-transmitting PET film 11 can maintain a high light transmittance, so that when light passes through the film, only a small amount of light energy is absorbed or scattered, and most of the light energy is retained and used for display, improving the brightness and clarity of the image. The main function of the light-blocking plate 12 is to isolate light, ensuring a more uniform distribution of light on the display panel 10 and reducing stray light interference.

[0071] Display panel 10, such as Figure 5 As shown, it features function indicator lights that work in conjunction with the light ring 56, a temperature indicator 15 for the real-time water temperature from the faucet, a child lock button 16, a temperature adjustment button 17, a water refill button 18, and a filter replacement indicator 19. The specific functions and operating instructions are as follows:

[0072] Press the knob: Rotate or press the button to turn on the water purifier. When turned on, the faucet interface light will perform a self-check and illuminate.

Rotating the knob 5 allows you to select cold water, warm water (green light), or hot water (red light). After selection, you need to press the button to confirm water dispensing.

[0073] The function indicator 14, in conjunction with the light ring 56, displays the following: When knob 5 is selected to cold water, the cold water indicator lights up, and light ring 56 displays blue. When knob 5 is selected to warm water, the warm water indicator lights up, and light ring 56 displays green. When knob 5 is selected to hot water, the hot water indicator lights up, and light ring 56 displays red.

[0074] The temperature display shows the real-time temperature of the water coming out of the faucet. A flame icon is located in the lower right corner of the temperature display to indicate the working status of the hot water tank; the flame illuminates as a red light when heating and extinguishes when keeping the water warm.

[0075] The child lock button 16 is illuminated by default when the water purifier is turned on. For safety, child lock 16 must be unlocked before selecting warm or hot water.

[0076] The temperature adjustment button 17 is used to select the temperature of the hot water tank. To the right of the temperature adjustment button 17, there are three adjustable display levels, corresponding to 98°, 90°, and 80°, which light up in turn.

[0077] The water replenishment button 18 is used for manually replenishing the hot water tank. The three bars in the middle indicate the real-time water temperature display: three bars indicate a water level above 80%, two bars indicate a water level between 80% and 20%, and one bar indicates a water level below 20%.

[0078] The filter replacement indicator 19 displays the real-time status of the filter cartridge. It displays white when the cartridge lifespan is above 20%, orange between 20% and 5%, and red below 5%. In these cases, it is recommended to replace the filter cartridge promptly to ensure water quality safety.

[0079] Body component 2, such as Figure 5 As shown, it includes an upper body 21 and a lower body 22. The panel assembly 1 is snapped into and watertightly connected to the body assembly 2. Specifically, the upper body 21 has a housing and a tube. The housing extends in the vertical pressing direction and is adapted to the panel assembly 1. The housing and the panel assembly 1 are connected by a snap-fit ​​55 and are watertightly connected. The tube extends in the pressing direction and is adapted to the lower body 22. The tube and the lower body 22 are fixed by side screws.

[0080] The water channel assembly 3 includes the water channel body, hot and cold silicone tubing, an exhaust pipe, and a waterproof data cable fixed to the water channel body. The water channel assembly 3 is snapped into the body assembly 2.

[0081] The pin fitting 4 is restricted from moving in the pressing direction by a lock nut 42 and is anti-rotationally connected to the main body assembly 2. Specifically, the inner wall of the lower body 22 is provided with several grooves circumferentially, and the pin fitting 4 is provided with a locking block 41 protruding from its axial direction and adapted to the groove in the direction of the inner wall of the lower body 22, so as to prevent the pin fitting 4 from disengaging from the lower body 22 in its extension direction, and is locked by a lock nut 42.

[0082] In this embodiment, the water purifier faucet integrates multiple functions into one unit, achieving an efficient, convenient, and intelligent water purification experience through the panel assembly 1, body assembly 2, water channel assembly 3, and pipe fittings 4. The push-button knob in the panel assembly 1 provides a stable and tactile operating experience, and its light ring 56, in conjunction with the function level indicator on the display panel 10, intuitively displays the current working status of the faucet. The display panel 10 also features a temperature indicator 15, which can display the temperature of the water coming out of the faucet in real time, providing users with accurate temperature information so that they can adjust the water temperature as needed. In addition, the inclusion of a child lock 16, temperature adjustment button 17, water refill button 18, and filter replacement indicator 19 further enriches the functionality of the faucet and enhances its safety and convenience.

[0083] In this embodiment, the snap-fit ​​and water-sealed connection between the panel assembly 1 and the body assembly 2 ensures the electrical safety of the main board 13. The snap-fit ​​fixing of the water channel assembly 3 and the body assembly 2 simplifies the installation process and improves the stability and reliability of the structure. The anti-rotation connection between the pin fitting 4 and the body assembly 2, as well as the use of the anti-loosening nut 42, effectively prevents the pin fitting 4 from loosening during long-term use, improving the stability and durability of the faucet structure.
