Description

Technical Field

[0001] This invention relates to the field of electric kettle technology, and in particular to an electric kettle panel control component and interactive control method. Background Technology

[0002] As a common household appliance, the user experience is directly affected by the ease of interaction and intuitive display of the control panel components of an electric kettle. In existing technology, electric kettle control panels typically use separate knobs and buttons. Knobs are used to adjust temperature or function, buttons are used to start or switch modes, and the display area is located elsewhere on the panel (such as an LED digital tube or LCD screen). However, when adjusting, users need to frequently shift their gaze between the knob and the display area, resulting in disjointed operation. Furthermore, the knobs themselves lack dynamic display capabilities, failing to provide real-time visual feedback on the currently adjusted parameters (such as temperature color zoning). Moreover, there is a lack of direct linkage feedback between the physical buttons on the panel and the main display area; users can only determine the trigger status through the button's backlight or beeping sound after pressing it, without a synchronized visual response on the main display area, resulting in a lack of interactivity. Therefore, there is an urgent need for an electric kettle control panel component that integrates button, knob, and display functions with intuitive interactive feedback. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an electric kettle panel control component and interactive control method.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: On one hand, the present invention provides an electric kettle panel control assembly, comprising: A PCB board having a rotary encoder module and a trigger switch, wherein the rotary encoder module has a fixed part and a rotating part that can rotate relative to each other; The knob housing is fixedly connected to the rotating part and is used to rotate under external force to generate an adjustment signal; The display module is fixedly connected to the fixing part and coaxially arranged with the knob housing; the display module can be pressed axially relative to the knob housing to trigger the trigger switch to generate a confirmation signal; A reset element is disposed between the display module and the knob housing, for resetting the display module after it is pressed; The panel button module includes at least one physical button, which is located on the PCB board. When the physical button is triggered, the display module provides corresponding display feedback.

[0005] Furthermore, the display module includes a latching component, a light-blocking component, a light-emitting disk, a display patch, and a light-transmitting mask. The latching component has a trigger post extending towards the PCB board in the center, which is used to abut the trigger switch when pressed. The light-blocking component is fixed to the latching component and has at least one light-transmitting hole. The light-emitting disk is clamped and fixed between the latching component and the light-blocking component, and a first LED light source is provided on the light-emitting disk. The display patch is attached to the outer surface of the light-blocking component and has a display pattern corresponding to the light-transmitting hole. The display pattern is transmitted and displayed when the first LED light source is lit. The light-transmitting mask covers the display patch and is fixedly connected to the latching component.

[0006] Furthermore, the panel button module also includes a panel patch and a light guide column. The panel patch covers the physical button, and the light guide column is integrally or linked with the physical button. The PCB board is also provided with a second LED light source, and the light emitted by the second LED light source is conducted through the light guide column to the light-transmitting marking area on the panel patch.

[0007] Furthermore, the first LED light source includes a variety of first-temperature LED beads, and the display pattern includes a temperature display area corresponding to the variety of first-temperature LED beads; the second LED light source includes a variety of second-temperature LED beads, and the light-transmitting marking area includes a temperature marking corresponding to the variety of second-temperature LED beads.

[0008] Furthermore, the first LED light source also includes a variety of first function operation button LED beads, the display pattern also includes a function operation button display area corresponding to the variety of first function operation button LED beads, the second LED light source also includes a variety of second function operation button LED beads, and the light-transmitting marking area also includes function operation button markings corresponding to the variety of second function operation button LED beads.

[0009] Furthermore, the first LED light source also includes a plurality of ambient LED beads, which are arranged circumferentially, and the display pattern also includes an annular ambient display area corresponding to the ambient LED beads.

[0010] Furthermore, the knob housing and the rotating part are fixedly connected by a first snap-fit ​​member, the first snap-fit ​​member including a first snap hole and a first snap-fit ​​protrusion that cooperate with each other, as well as a first positioning groove and a first embedding part that cooperate with each other; the fastener and the fixing part are fixedly connected by a second snap-fit ​​member, the second snap-fit ​​member including a second snap hole and a second snap-fit ​​protrusion that cooperate with each other, as well as a second positioning groove and a second embedding part that cooperate with each other.

[0011] On the other hand, the present invention also provides an interactive control method based on the above-mentioned electric kettle panel control component, comprising: In response to any physical button in the trigger panel button module, a function control signal corresponding to that physical button is generated; Based on the function control signal, the first LED light source in the display module corresponding to the function of the physical button is synchronously controlled to light up or change color. Based on the function control signal, the electric kettle function corresponding to the physical button is executed.

[0012] Furthermore, the step of synchronously controlling the first LED light source in the display module corresponding to the function of the physical button to light up or change color according to the function control signal includes: When the physical button that is triggered is the temperature setting button, the first temperature LED in the control display module corresponding to the temperature range is lit up, and the temperature display area displays the corresponding temperature color. When the triggered physical button is a function operation button, the corresponding first function operation button LED in the control display module lights up, and the corresponding function icon is displayed in the function operation button display area.

[0013] Furthermore, it also includes: A start signal is generated in response to the panel control components being powered on; Based on the start signal, control multiple ambient LED beads to light up; After all the ambient LED beads are lit, control the multiple ambient LED beads to enter a breathing light mode with periodic brightness changes.

[0014] The advantages of this invention compared to existing technologies are as follows: By fixing the knob housing to the rotating part of the rotary encoder module and fixing the display module to the fixed part and setting them coaxially, the display content always faces the user and does not rotate with the knob during rotation adjustment, improving the convenience of parameter reading; at the same time, the display module can be pressed axially independently of the knob housing to trigger a confirmation signal, and with the help of the reset element, the press rebound is realized, highly integrating the two operation logics of rotation selection and press confirmation into the same knob structure, making the operation smooth and the feel clear; in addition, by setting up a panel button module and synchronously controlling the corresponding first LED light source in the display module to light up or change color when it is triggered, a direct visual linkage between the physical buttons and the main display area is established, and the user can get clear button operation feedback from the display module in the center of the knob without shifting their gaze, significantly enhancing the intuitiveness and consistency of human-computer interaction.

[0019] The technical solution of the present invention will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0022] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0023] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.

[0024] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0025] like Figures 1 to 8As shown, this embodiment of the invention provides a control assembly for an electric kettle panel. The assembly includes a PCB board 4, a knob housing 3, a display module 2, a reset element 7, and a panel button module 1. The PCB board 4 serves as the circuit support and signal processing core of the entire control assembly, and is equipped with a rotary encoder module 5 and a trigger switch 6. The rotary encoder module 5 has electronic components, such as a rotary encoder or rotary potentiometer, with a relatively rotatable fixed part 51 and a rotating part 52. The fixed part 51 remains stationary, while the rotating part 52 can rotate around an axis under external force and output an electrical signal corresponding to the rotation angle or gear position. The trigger switch 6 can be a tactile switch, a membrane switch, or a micro switch, used to generate a confirmation signal in response to a pressing action. The knob housing 3 is a shell component for the user to hold and rotate, and it is fixedly connected to the rotating part 52 of the rotary encoder module 5. When the user applies a rotational torque, the knob housing 3 drives the rotating part 52 to rotate together, and the rotary encoder module 5 generates an adjustment signal accordingly. This adjustment signal can be used to set the target temperature of the electric kettle or select the operating mode. The display module 2 is fixedly connected to the fixing part 51 of the rotary encoder module 5 and is coaxially arranged with the knob housing 3. Since the display module 2 is connected to the fixing part 51, and the fixing part 51 does not rotate with the rotating part 52, the display module 2 maintains a fixed position during the rotation of the knob housing 3, and its displayed content does not rotate with the knob housing 3, thus facilitating information reading from a fixed angle. Simultaneously, the display module 2 can be pressed axially relative to the knob housing 3; that is, the user can press the display module 2 towards the PCB board 4, causing axial displacement of its entirety or a portion, thereby triggering the trigger switch 6 located below it to generate a confirmation signal. A reset element 7 is disposed between the display module 2 and the knob housing 3, specifically one or more compression springs, spring sheets, or elastic rubber parts. When the user releases the pressure, the reset element 7 provides elastic restoring force, causing the display module 2 to automatically return to its initial unpressed position for the next press confirmation. The panel button module 1 includes at least one physical button 11, which is mounted on the PCB board 4 and located on the side of the knob housing 3. The physical buttons 11 can be used to directly activate specific functions, such as boiling, keeping warm, timer, or power switch. When a user triggers any physical button 11, the microcontroller on the PCB board 4 responds to the trigger signal and controls the display module 2 to display feedback corresponding to the button's function, such as illuminating the corresponding icon or changing the display color. This structural design allows the display module 2 at the center of the knob not only to display the rotation adjustment parameters but also to serve as the primary visual feedback area for the operation of the physical buttons 11. This allows the user to confirm the validity of the button operation without taking their eyes off the knob area, significantly improving the focus and intuitiveness of the interaction.

[0026] By connecting the display module 2 to the fixing part 51 of the rotary encoding module 5 and the knob housing 3 to the rotating part 52, the display content does not rotate with the knob during rotation adjustment, making it easy to read. The display module 2 can be pressed independently and configured with a reset element 7, integrating the rotation selection and press confirmation operations into the same knob structure, making the operation smooth and the feel clear. When the panel button is triggered, the display module 2 is driven to provide feedback, establishing a visual linkage between the button and the main display area, improving human-computer interaction and user experience.

[0027] exist Figure 4 In the illustrated embodiment, the display module 2 includes a mounting bracket 21, a light-blocking component 22, a light-emitting disk 23, a display patch 24, and a light-transmitting cover 25. The mounting bracket 21 serves as the support frame for the display module 2, and has a trigger post extending towards the PCB board 4 at its center. The trigger post is aligned with the trigger switch 6; when the user presses the display module 2, the trigger post directly contacts and triggers the trigger switch 6. The light-blocking component 22 is fixed to the mounting bracket 21. The light-blocking component 22 is made of opaque or semi-transparent plastic material with light-blocking function, and has at least one light-transmitting hole 221. The shape and position of the light-transmitting hole 221 correspond to the information area to be displayed. The light-emitting disk 23 is clamped and fixed between the mounting bracket 21 and the light-blocking component 22, and has a first LED light source. The first LED light source can be a surface-mount LED or a through-hole LED, and its color and quantity are determined according to design requirements. The display patch 24 is attached to the outer surface of the light-blocking component 22. The display patch 24 has a display pattern printed or etched on it, corresponding to the light-transmitting hole 221. The display pattern can be a temperature value, function icon, water level indicator, etc. When the first LED light source is lit, light passes through the light-transmitting hole 221 on the light-blocking component 22, illuminating the corresponding display pattern on the display patch 24 from the back, causing the pattern to be displayed. A light-transmitting mask 25 covers the display patch 24 and is fixedly connected to the fastener 21. The light-transmitting mask 25 is made of transparent or semi-transparent material, protecting the display patch 24 from external contamination and wear while allowing the displayed light to pass through. The entire display module 2, as an independent sub-component, can be pre-assembled and then installed onto the fixing part 51 of the rotary encoder module 5, facilitating production and maintenance.

[0028] The layered structure of the fastener 21, light-blocking component 22, light-emitting disk 23, display patch 24, and light-transmitting mask 25 enables the zoned transmission display of the display pattern. The light-blocking component 22 effectively prevents light crosstalk between adjacent light-transmitting holes 221, ensuring the clarity and contrast of the displayed content.

[0029] exist Figure 3In the illustrated embodiment, the panel button module 1 further includes a panel patch 12 and a light guide post 13. The panel patch 12 covers the physical button 11, and its surface can be printed with text or icons indicating the button functions. The panel patch 12 can be made of a flexible material such as silicone or film to facilitate elastic deformation when pressed. The light guide post 13 is integrally or linked with the physical button 11. The light guide post 13 is made of a light-transmitting material, with its lower end close to the PCB board 4 and its upper end close to the back of the panel patch 12. The PCB board 4 is also provided with a second LED light source 14, the position of which is aligned with the lower end of the light guide post 13. When the second LED light source 14 is lit, light enters the light guide post 13 and is transmitted to the light-transmitting marking area on the panel patch 12 through total internal reflection or refraction, thus illuminating the button markings on the panel patch 12. When the user presses the panel patch 12, the touch switch below the physical button 11 is triggered, and the light guide column 13 moves down with the button, but the light guide path of the light guide column 13 can still maintain the effective transmission of light.

[0030] The light guide pillars 13 can be designed as multiple independent light guide pillars 13 corresponding to different buttons, or an integrated light guide plate can be used to cover multiple button areas. In addition, the second LED light source 14 can use LEDs of different colors to distinguish the functional states of different buttons, such as white backlight when in standby mode and blue backlight when activated.

[0031] The light from the second LED light source 14 on the PCB board 4 is precisely transmitted to the light-transmitting marking area of ​​the panel patch 12 through the light guide column 13, realizing local backlighting of the buttons, so that users can clearly identify the button functions even in low light environment.

[0032] exist Figure 6In the illustrated embodiment, the first LED light source includes various first-temperature LED beads 231. For example, the knob housing 3 can rotate 16 increments, with a temperature range of 25-100 degrees Celsius, corresponding to blue, green, yellow, and red LED beads in four different colors for four temperature ranges: 25-40 degrees Celsius, 45-60 degrees Celsius, 65-80 degrees Celsius, and 85-100 degrees Celsius. The display pattern includes temperature display areas corresponding to these first-temperature LED beads 231. For example, four fan-shaped areas or four independent icon areas are divided on the display patch 24, each area corresponding to a temperature range. The second LED light source 14 also includes various second-temperature LED beads, and the light-transmitting marking area on the panel patch 12 also includes temperature markings corresponding to the second-temperature LED beads. For example, the panel has four temperature setting buttons for 40 degrees Celsius, 60 degrees Celsius, 80 degrees Celsius, and 100 degrees Celsius. Each button has a corresponding color second LED bead below it, and the button markings themselves are also printed or translucent in that color. When the user rotates the knob to select the target temperature or when the water temperature reaches the target temperature, only the first temperature LED bead 231 corresponding to that temperature range is lit, and the display module 2 displays the corresponding color; when the user directly presses the temperature setting button on the panel, the corresponding second LED bead lights up, and at the same time, the corresponding first temperature LED bead 231 in the display module 2 also lights up simultaneously, forming dual color feedback.

[0033] Different temperature ranges are represented by color partitions, allowing users to quickly identify the currently set temperature range by color without having to read specific numbers; the temperature indicators on the panel buttons are consistent with the color feedback of display module 2, enhancing the consistency of operation.

[0034] exist Figure 6 In the illustrated embodiment, the first LED light source also includes various first function operation button LED beads 232, such as LED beads corresponding to functions like boiling, keeping warm, timer, and dechlorination. The display pattern also includes a function operation button display area corresponding to these first function operation button LED beads 232, that is, a corresponding function icon area is set on the display patch 24. The second LED light source 14 also includes various second function operation button LED beads, and the light-transmitting marking area on the panel patch 12 also includes function operation button markings corresponding to the second function operation button LED beads. When the user presses a function button on the panel (such as boiling), the second function operation button LED bead corresponding to that button lights up, and at the same time, the corresponding first function operation button LED bead 232 in the display module 2 also lights up simultaneously, displaying a boiling icon, such as a bubble pattern of boiling water, on the display patch 24. In this way, the user can obtain intuitive function confirmation from the display module 2 at the center of the knob the moment the button is pressed.

[0035] exist Figure 6In the illustrated embodiment, the first LED light source further includes multiple ambient LED beads 233, which are arranged circumferentially along the display module 2. For example, a ring of 16 white LED beads is arranged around the outer edge of the light-emitting disk 23. The display pattern also includes an annular ambient display area corresponding to these ambient LED beads 233, i.e., an annular light-transmitting area on the display patch 24. When the ambient LED beads 233 are lit, light shines outward from the annular area of ​​the knob cover, forming a halo around the center of the knob. The ambient LED beads 233 can be controlled independently of the temperature display beads and function button beads to provide device status prompts (such as standby, working, completed) or power-on animation effects.

[0036] The circumferentially arranged ambient LED beads 233 enrich the visual expression of the display module 2, which can convey status information in addition to temperature and function, and also enhance the product's appearance appeal.

[0037] exist Figure 4 , Figure 7 and Figure 8 In the illustrated embodiment, the knob housing 3 and the rotating part 52 of the rotary encoder module 5 are fixedly connected by a first snap-fit ​​member. The first snap-fit ​​member includes a first snap hole 32 and a first snap protrusion 521 that cooperate with each other, as well as a first positioning groove 522 and a first insert 31 that cooperate with each other. For example, the inner sidewall of the knob housing 3 is provided with a plurality of first snap protrusions 521, while the outer sidewall of the rotating part 52 is provided with corresponding first snap holes 32; or vice versa. The first positioning groove 522 and the first insert 31 are used to ensure that the knob housing 3 and the rotating part 52 are accurately positioned in the circumferential direction, preventing slippage or eccentricity during rotation. Similarly, the fastener 21 and the fixing part 51 of the rotary encoder module 5 are fixedly connected by a second snap-fit ​​member. The second snap-fit ​​member includes a second snap hole 511 and a second snap protrusion 212 that cooperate with each other, as well as a second positioning groove 512 and a second insert 211 that cooperate with each other. The second positioning groove 512 and the second insert 211 can also be designed as a foolproof structure, for example, the upper and lower parts have different dimensions, so that the fastener 21 can only be installed on the fixing part 51 in one correct direction, avoiding assembly errors. The fixing method of snap-fit ​​and positioning eliminates the need for additional fasteners and improves assembly efficiency.

[0038] like Figures 1 to 9 As shown, this embodiment of the invention also provides an interactive control method based on the above-mentioned electric kettle panel control component, the method including the following steps: S10-S30.

[0039] S10. In response to any physical button 11 in the trigger panel button module 1, generate a function control signal corresponding to that physical button 11.

[0040] The signal can be a digital code or a level change, indicating which button was pressed and the corresponding function of the button (such as setting the temperature to 40 degrees, starting boiling, etc.).

[0041] S20. According to the function control signal, synchronously control the first LED light source in the display module 2 corresponding to the function of the physical button 11 to light up or change color.

[0042] For example, if the temperature setting button 60 degrees is pressed, the first temperature LED 231 corresponding to the green temperature range in display module 2 will light up, and the temperature display area on display patch 24 will also turn green. If the "keep warm" function button is pressed, the first function operation button LED 232 corresponding to the keep warm icon area in display module 2 will light up.

[0043] S30. Based on the function control signal, execute the electric kettle function corresponding to the physical button 11.

[0044] For example, starting the heating to the set temperature, starting the heat preservation cycle, etc.

[0045] For steps S10-S30, the triggering of the panel buttons is directly linked to the display feedback of the display module 2. When operating the buttons, the user can obtain clear visual confirmation without taking their eyes off the knob area, which improves interaction efficiency and user experience.

[0046] In some embodiments, differentiated display feedback is provided for different types of buttons. Specifically, when the triggered physical button 11 is a temperature setting button, the first temperature LED bead 231 in the control display module 2 corresponding to the temperature range is illuminated, and the temperature display area displays the corresponding temperature color. For example, pressing the 45-60 degree button illuminates the green LED bead in the display module 2, and the temperature display area displays green. When the triggered physical button 11 is a function operation button, the corresponding first function operation button LED bead 232 in the control display module 2 is illuminated, and the corresponding function icon is displayed in the function operation button display area. For example, pressing the dechlorination button illuminates the LED in the dechlorination icon area of ​​the display module 2, and the icon is displayed as a pattern of bubbles rising from the water.

[0047] By using different display elements to provide feedback for two different types of buttons—temperature setting and function operation—users can easily determine whether they are adjusting the temperature or turning on a function based on the displayed content, making it easier for them to distinguish between them.

[0048] In some embodiments, the interactive control method based on the above-described electric kettle panel control component further includes the following steps: When the panel control component is connected to a power source (e.g., an electric kettle plugged into a power outlet), the control component detects the power connection and generates a start signal. Then, based on the start signal, it controls multiple ambient LED beads 233 in display module 2 to light up sequentially, for example, in a clockwise or counter-clockwise order. Each bead lights up and remains lit before lighting the next, until all ambient LED beads 233 are lit. After all are lit, all ambient LED beads 233 enter a breathing light mode with periodic brightness changes, i.e., the brightness gradually increases and then decreases again, repeating cyclically. Throughout the initialization process, or at least after all ambient LED beads 233 are lit, the first LED light source corresponding to the power indicator pattern in display module 2 (e.g., the LED corresponding to the power switch icon on display patch 24) lights up to its first color (e.g., red) to indicate to the user that the device is powered on and in standby mode.

[0049] The sequential lighting of the 233 ambient LED beads can be configured for specific durations, such as a total duration of 6 seconds with each bead spaced 0.375 seconds apart. The breathing light mode cycle can be set to 2 seconds. The power indicator can also use a flashing method, for example, the power icon flashes at a slower frequency in breathing light mode.

[0050] The sequential lighting of the 233 ambient LED beads and the breathing light effect provide users with a clear visual feedback when the device is turned on, enhancing the sense of technology and quality of the device.

[0051] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
