Description

Technical Field

[0001] This utility model relates to the field of electronic handle structures. More specifically, this utility model relates to a novel faucet electronic handle structure. Background Technology

[0002] With social development and improved living standards, people's demands for quality of life have also increased, leading to the emergence of new types of faucets. For example, patent CN218845193U discloses a faucet that integrates hot and cold tap water and hot and cold purified water. It includes a faucet body and a control device. The faucet body includes a kitchen faucet structure for hot and cold tap water dispensing and a water purification structure for hot and cold purified water dispensing. The control device includes a valve core seat and a valve core. The kitchen faucet structure is threadedly connected to the valve core seat, and the valve core is connected to the valve core seat via a pressure cap and a handle. This faucet integrates hot and cold tap water and hot and cold purified water, and also features… It features flushing, microbubble water output, and hot and cold water purification functions to meet various consumer needs. An electronic control component for securing the power signal cable is located above the inner cavity. Above the electronic control component is a touch panel. Through data exchange between the electronic control component and the water purifier, the water quality, heating temperature, and filter life information are displayed on the touch panel. The panel displays information such as cold water extraction, hot water extraction, inlet TSD value, outlet TDS value, lock button, heating button, water temperature display, water shortage display, and filter life display. During use, users select the desired water purification state (cold water, hot water, aerated water) as well as the water flow rate and temperature to obtain the desired purified water.

[0003] However, the above design relies entirely on the touch panel for water purification, which presents several problems, primarily as follows: Firstly, touch panels function by detecting touch position and action, leading to a high probability of misoperation. Furthermore, unlike traditional mechanical buttons, touch panels lack the tactile feedback of physical buttons, making it difficult for users to determine if they have successfully triggered a function, resulting in repeated operations and low efficiency. Secondly, the manufacturing process of touch panels is relatively complex, especially for high-precision, high-sensitivity panels, which require advanced materials and manufacturing technologies. This results in higher manufacturing costs, leading to higher prices for devices using touch panels. Moreover, repair costs are also high when the touch panel malfunctions, as repairs require specialized technicians and equipment.

[0004] Therefore, there is an urgent need for an electronic handle structure that does not rely on a touch panel, in order to reduce unnecessary buttons and be convenient and efficient to use. Utility Model Content

[0005] One object of this invention is to solve at least the problems described above and to provide at least the advantages that will be explained later.

[0006] Another objective of this invention is to provide a novel electronic faucet handle structure. By rotating the handle and pressing the button in conjunction with the display screen, users can select the desired function / parameter by referring to the display screen, reducing unnecessary switches and buttons. This makes the faucet convenient to use, highly efficient, low in cost, and easy to maintain.

[0007] To achieve these objectives and other advantages according to the present invention, a novel faucet electronic handle structure is provided, comprising:

[0008] The outer casing has a circular groove at one end and a connector that can be detachably connected to the faucet body at the other end.

[0009] A display screen is mounted on the housing;

[0010] A first PCB board is fixed inside the housing. A spring-loaded electronic micro switch and a ring encoder coaxial with the circular slot are provided at one end of the first PCB board near the circular slot. The ring encoder is sleeved outside the spring-loaded electronic micro switch. A connecting seat is coaxially provided on the moving part of the ring encoder. The end of the connecting seat away from the first PCB board extends out of the housing.

[0011] A cylindrical rotating handle, one end of which is coaxially connected to the outer wall of the protruding end of the connecting seat;

[0012] The button assembly includes a button plate and a pressing rod. The button plate is located on the end of the rotary handle away from the first PCB board. One end of the pressing rod is connected to the pressing rod, and the other end slides into the center of the ring encoder and is attached to the spring-loaded electronic micro switch. When an external force presses the button plate, the pressing rod transmits the external force to the spring-loaded electronic micro switch. When the external force disappears, the pressing rod and the button plate are reset under the rebound action of the spring-loaded electronic micro switch.

[0013] Preferably, the connecting seat includes a first tube and a second tube coaxially connected. The end of the first tube away from the second tube extends into the circular slot. A first sealing ring is fitted on the extended end of the first tube, and the outer circumferential wall of the first sealing ring is tightly fitted to the inner wall of the circular slot. The outer circumferential wall of the second tube is engaged with the inner circumferential wall of the rotary handle, and the inner circumferential wall of the second tube is engaged with the moving part of the ring encoder.

[0014] Preferably, the outer casing is made of a semi-transparent black material; it also includes a pair of mounting plates, which are spaced apart and coaxially disposed at one end of the outer casing near the faucet body. The first PCB board is detachably connected to the mounting plate away from the faucet body. A support plate is connected between the pair of mounting plates, and the display screen is mounted on the support plate.

[0015] Preferably, the end of the button lever away from the first PCB board is provided with a circular groove-shaped button cover, the groove of the button cover facing the ring encoder, and the back end of the button cover is connected to the button piece by adhesive tape.

[0016] Preferably, a second sealing ring is provided on the outer circumferential wall of the button cover. The second sealing ring is located on the side of the second tube away from the first tube, and the outer circumferential wall of the second sealing ring is tightly fitted to the inner wall of the circular groove.

[0017] Preferably, a horizontal plate is horizontally connected between a pair of mounting plates, and a pair of shelves are provided on the horizontal plate. A second PCB board for mounting functional lights is placed on the pair of shelves. The system also includes an auxiliary bracket, which is provided on the horizontal plate. The auxiliary bracket has multiple functional light mounting holes located above the functional PCB board. Multiple functional icons are provided on the outer wall of the housing, and each functional icon corresponds to one of the multiple functional light mounting holes.

[0018] Preferably, the button lever is snap-fitted to the inner wall of the ring encoder, so that the end of the button lever near the first PCB board slides along the inner wall of the ring encoder.

[0019] Preferably, the button piece is a CD-patterned decorative cover.

[0020] This utility model has at least the following beneficial effects:

[0021] This invention provides a novel electronic faucet handle structure by designing a housing, circular slot, connector, first PCB board, spring-loaded electronic micro switch, ring encoder, connector, rotary handle, button plate, pressing rod, and display screen. Through the coordinated operation of the rotary handle, pressing rod, and display screen, during use, the rotary handle is rotated while referring to the display screen, causing the ring encoder's rotor to rotate. The ring encoder acquires the angular displacement of the rotary handle and converts it into an electrical signal. This electrical signal can be used to control the switching of usage modes (such as room temperature water, ice water, sparkling water) or parameters (such as temperature), and is displayed on the screen. By pressing the pressing rod, external force is transmitted to the spring-loaded micro switch. Under external force, the spring-loaded micro switch generates an electrical signal, which can be used to control the selection of the desired usage mode or parameter. Overall, compared to existing designs that directly use a touch panel to select / select the desired usage mode, function, or parameter, this invention reduces unnecessary switch buttons and is convenient to use, highly efficient, low-cost, and easy to maintain.

[0022] Other advantages, objectives and features of this invention will be partly apparent from the following description, and partly understood by those skilled in the art through study and practice of this invention. Attached Figure Description

Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0028] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0029] like Figure 1-3 As shown, this utility model provides a novel electronic faucet handle structure, comprising:

[0030] The outer casing 1 has a circular groove at one end and a connector 5 that can be detachably connected to the faucet body at the other end.

[0031] Display screen 4 is mounted on the housing 1;

[0032] A first PCB board 6 is fixed inside the outer casing 1. A spring-loaded electronic micro switch 7 and a ring encoder 8 coaxial with the circular slot are provided at one end of the first PCB board 6 near the circular slot. The ring encoder 8 is sleeved outside the spring-loaded electronic micro switch 7. A connecting seat 9 is coaxially provided on the moving part of the ring encoder 8. The end of the connecting seat 9 away from the first PCB board 6 extends out of the outer casing 1.

[0033] A cylindrical rotating handle 2, one end of which is coaxially connected to the outer wall of the protruding end of the connecting seat 9;

[0034] The button assembly includes a button piece 10 and a pressing rod 11. The button piece 10 is located on the end of the rotary handle 2 away from the first PCB board 6. One end of the pressing rod 11 is connected to the pressing rod 11, and the other end slides into the center of the ring encoder 8 and is attached to the spring-loaded electronic micro switch 7. When the button piece 10 is pressed by an external force, the pressing rod 11 transmits the external force to the spring-loaded electronic micro switch 7. When the external force disappears, the pressing rod 11 and the button piece 10 are reset under the spring-loaded action of the spring-loaded electronic micro switch 7.

[0035] In the above technical solution, one end of the outer shell 1 is provided with a circular groove and the other end is provided with a connector 5. The inner cavity shape of the outer shell 1 is not limited in any way, but for ease of processing, it is preferred that the outer shell 1 be made into a cylindrical shape. The outer shell 1 is made of waterproof and strong plastic material by injection molding. The structure of the connector 5 is not limited, as long as it is convenient to connect with the faucet body. For example, it can be designed as an internal thread structure to connect with the faucet body by thread, so as to achieve a detachable connection, which is convenient for maintenance and replacement. In actual design, a rubber sealing ring can also be equipped at the connector 5 to ensure the water tightness of the connection and prevent water leakage.

[0036] The outer casing 1 contains a first PCB board 6, which can be fixed with screws or clips to ensure stable installation. A spring-loaded electronic micro switch 7 and a ring encoder 8 are soldered onto the area near the circular slot on the first PCB board 6. The ring encoder 8 is coaxial with the circular slot and is sleeved outside the spring-loaded electronic micro switch 7. The ring encoder 8 can be a high-precision photoelectric ring encoder. A connecting seat 9 is coaxially connected to the moving part (i.e., the rotating component) of the ring encoder 8. One end of the connecting seat 9 extends out of the outer casing 1, and a rotating handle 2 is coaxially connected to the extended end of the connecting seat 9. The rotating handle 2 can be connected to the connecting seat 9 by screws or snap-fit ​​connections. Rotating the rotating handle 2 will drive the moving part of the ring encoder 8 to rotate through the connecting seat 9. The ring encoder 8 then obtains the angular displacement of the rotating handle 2 and generates an electrical signal. This electrical signal can be used to control the switching of usage modes (such as room temperature water, cold water, hot water, sparkling water, etc., the same below) or parameters (such as temperature, water volume, etc., the same below).

[0037] The button assembly includes a button plate 10 and a pressing rod 11. The button plate 10 can be made of metal for easy pressing operation. The button plate 10 is located at the end of the rotary handle 2 away from the first PCB board 6 by adhesive or snap-fit. The pressing rod 11 is located inside the rotary handle 2. One end of the pressing rod 11 abuts against the button plate 10, and the other end slides into the center of the ring encoder 8 and is attached to the spring-loaded micro-electronic switch. Thus, when an external force presses the button plate 10, the pressing rod 11 moves towards the spring-loaded micro-electronic switch, thereby pressing the spring-loaded micro-electronic switch. When the switch is pressed, it generates an electrical signal, which can be used to control the selection of the desired usage mode or parameters. There are various ways to set the pressing rod 11 in the rotary handle 2. Here is one example: one end of the pressing rod 11 is located on the side wall of the button plate 10 near the first PCB board 6, and the other end slides into the ring encoder 8. The part of the pressing rod 11 that extends into the ring encoder 8 is adapted to the size of the inner ring of the ring encoder 8 (the inner ring is the shaft in the ring encoder stator that is coaxial with the rotor), so that the inner ring of the ring encoder 8 guides the pressing rod 11, which can ensure the accuracy of external force transmission.

[0038] The display screen 4 is mounted on the outer casing 1. Specifically, the display screen 4 can be embedded in a pre-reserved groove in the outer casing 1. The display screen 4 can be a high-resolution OLED display screen, which can achieve high-definition display effect and enhance the user's visual experience. The display screen 4 can display a variety of information, such as the current usage mode and temperature, so that users can understand the environmental conditions and equipment status at any time. When the user operates the rotating handle 2 to perform switching operations or select operations, the information is displayed on the display screen 4.

[0039] In the above technical solution, during use, when the user needs to switch the faucet's operating mode or parameters, they observe the display screen 4 and then rotate the rotary handle 2. The rotary handle 2 drives the connecting seat 9 and the moving part of the ring encoder 8 to rotate synchronously. The ring encoder 8 converts the angular displacement signal into an electrical signal according to the rotation angle of the moving part. This electrical signal is used to control the switching of operating modes or parameters and is displayed on the display screen. The user can switch between various operating modes or parameters by operating the rotary handle 2 according to the display screen 4, so as to switch to the desired operating mode or parameter. When the user observes the display screen 4 and operates the rotary handle 2 to switch to a certain operating mode or parameter, they only need to press the button piece 10. The external force is transmitted to the spring-loaded electronic micro switch 7 through the pressing rod 11. The micro switch closes instantly, generating a selected electrical signal. This electrical signal is used to lock the currently selected operating mode / parameter. When the external force disappears, the spring-loaded electronic micro switch 7 relies on its own elastic rebound to drive the pressing rod 11 and the button piece 10 to reset, ready for the next operation.

[0040] The beneficial effects of adopting this technical solution are as follows: by designing the outer shell 1, circular slot, connector 5, first PCB board 6, spring-loaded electronic micro switch 7, ring encoder 8, connector 9, rotating handle 2, button piece 10, pressing rod 11, and display screen 4, a new type of faucet electronic handle structure is provided, which has the following beneficial effects: (1) Multifunctional integration: through rotation and pressing operations, users can switch between different usage modes or adjust parameters, reduce unnecessary switch buttons, make the device interface more concise and practical. For example, when applied to a smart kitchen faucet, the current usage mode or parameters are displayed on the display screen 4, and users can intuitively understand the working status of the device and make precise adjustments; (2) Operation convenience and user experience: through the display screen 4. Users can view it intuitively and operate it easily with the rotating handle 2 and button 10, which reduces the difficulty of use and improves the accuracy and convenience of operation; (3) Ease of installation and maintenance: On the one hand, this utility model can be processed into products with standardized interfaces and sizes, which can be directly plugged into or installed in the equipment, simplifying the installation process and reducing the installation cost. On the other hand, since the design of electronic handles is usually more modular, when a fault occurs, users can easily replace or repair the relevant parts, reducing the difficulty and cost of maintenance; (4) Cost-effectiveness advantage: This electronic handle adopts an integrated and modular design, which reduces the development mold cost and unnecessary button cost of equipment manufacturers, has strong competitiveness, and can meet the needs and preferences of different users.

[0041] In another technical solution, the connecting seat 9 includes a first tube 901 and a second tube 902 coaxially connected. The end of the first tube 901 away from the second tube 902 extends into the circular slot. A first sealing ring 12 is sleeved on the extended end of the first tube 901, and the outer circumferential wall of the first sealing ring 12 is tightly fitted to the inner wall of the circular slot. The outer circumferential wall of the second tube 902 is engaged with the inner circumferential wall of the rotary handle 2, and the inner circumferential wall of the second tube 902 is engaged with the moving part of the ring encoder 8.

[0042] In the above technical solution, the connecting seat 9 includes a first tube 901 and a second tube 902 coaxially connected. The first tube 901 and the second tube 902 are integrally formed to ensure their coaxiality. The end of the first tube 901 away from the second tube 902 extends into the circular groove. An annular groove is provided on the tube body of the first tube 901 that extends into the circular groove. A first sealing ring 12 is provided in the annular groove. The first sealing ring 12 is tightly attached to the inner wall of the outer shell 1 to ensure the rotational sealing connection between the connecting seat 9 and the outer shell 1, and to prevent external environment such as water and water vapor from entering the outer shell 1 and affecting the components inside the outer shell 1.

[0043] The second tube 902 extends coaxially into the rotary handle 2 at one end away from the first tube 901. A first snap-fit ​​structure is machined on the outer circumference of the second tube 902, and a first slot adapted to the first snap-fit ​​structure is machined on the inner circumference of the rotary handle 2, so that the second tube 902 and the rotary handle 2 are snap-fit ​​connected. To improve connection stability, multiple first snap-fit ​​structures and first slots are preferably designed. A second snap-fit ​​structure is provided on the inner circumference of the second tube 902, and a second slot structure adapted to the second snap-fit ​​structure is machined on the outer circumference of the moving part of the ring encoder 8, so that the second tube 902 and the moving part of the ring encoder 8 are snap-fit ​​connected. To improve connection stability, multiple second snap-fit ​​structures and second slots are preferably designed.

[0044] In this technical solution, during assembly, the first PCB board 6, with the ring encoder 8 and the spring-loaded micro-electronic switch soldered together, is first installed inside the housing 1. Then, the first sealing ring 12 is installed on the first tube 901, so that the second snap-fit ​​structure corresponds to the corresponding second slot. The connecting seat 9 is connected to the moving part of the ring encoder 8 using a snap-fit ​​connection. At the same time, the first tube 901 of the connecting seat 9 is inserted into the circular slot of the housing 1. Then, the first snap-fit ​​structure is aligned with the corresponding first slot, and the rotating handle 2 is installed on the connecting seat 9 using a snap-fit ​​connection. In use, external force rotates the rotating handle 2, which drives the second tube 902 to rotate. The second tube 902 drives the moving part of the ring encoder 8 to rotate, while the first tube 901 rotates on the inner wall of the running slot. The beneficial effects of this technical solution are that it is convenient for assembly and disassembly, the connection is stable, and the transmission effect is good.

[0045] In another technical solution, the outer shell 1 is made of semi-transparent black material; it also includes a pair of mounting plates 14, which are spaced apart and coaxially disposed at one end of the outer shell 1 near the faucet body. The first PCB board 6 is detachably connected to the mounting plate 14 away from the faucet body. A support plate 15 is connected between the pair of mounting plates 14, and the display screen 4 is mounted on the support plate 15.

[0046] In the above technical solution, the outer shell 1 is made of semi-transparent black material. Semi-transparent black polycarbonate (PC) material can be used to manufacture the outer shell 1. Polycarbonate has good mechanical properties, optical properties, and weather resistance. The semi-transparent black appearance satisfies aesthetic requirements and can hide the internal structure to a certain extent, while not obstructing the light transmitted through the display screen 4. A pair of mounting plates 14 are provided inside the outer shell 1. The pair of mounting plates 14 are coaxially arranged with the outer shell 1. Specifically, the shape of the mounting plates 14 is designed to be circular, with a diameter slightly smaller than the inner diameter of the outer shell 1, to ensure coaxial installation inside the outer shell 1. Of the pair of mounting plates 14, the one closer to the outer shell 1... The first PCB board 6 is installed on the side wall of the mounting plate 14 near the open end of the shell 1. Specifically, the first PCB board 6 is screwed onto the mounting plate 14. A support plate 15 is provided between the pair of mounting plates 14. The two ends of the support plate 15 are respectively fixed to the pair of mounting plates 14. The support plate 15 is located at the eccentric position of the mounting plate 14. The display screen 4 is installed on the side wall of the support plate 15 near the shell 1. When the display screen 4 is actually used, an OLED display screen 4 of appropriate size and resolution is selected. Its brightness and contrast should be able to meet the clear display requirements under different ambient light conditions.

[0047] In this technical solution, the device can be tested before its official use, specifically as follows: Power on the device and check if the display screen 4 can light up normally and if the displayed content is clear and accurate. Test the visibility of the display screen 4 under different ambient light intensities. If necessary, adjust the brightness and contrast settings of the display screen 4 to ensure that users can clearly read the information on the display screen 4 in various usage scenarios. Manually rotate the rotary handle 2 and observe whether the ring encoder 8 can accurately output the signal used to switch functions / parameters and display it correctly on the display screen 4. When the test is normal, it can be used. Any abnormalities that occur during the test can be dealt with promptly. The beneficial effect of this technical solution is that by setting a semi-transparent black outer shell 1 and a support plate 15 to mount the display screen 4, the display screen 4 can be protected inside the outer shell 1, avoiding interference from the external environment and further improving the service life of the display screen 4.

[0048] In another technical solution, the end of the button lever away from the first PCB board 6 is coaxially provided with a circular groove-shaped button cover 16. The groove opening of the button cover 16 faces the ring encoder 8, and the back end of the button cover 16 is connected to the button piece 10 by adhesive tape. Specifically, the button cover 16 is cylindrical groove-shaped, with its groove opening facing the first PCB board 6. The end of the pressing rod 11 away from the first PCB board 6 is coaxially fixed to the bottom of the groove of the button cover 16. The outer wall of the groove bottom of the button cover 16 is connected to the button piece 10 by adhesive tape. In actual use, in order to reduce the lateral movement of the overall device... The volume can be adjusted so that an annular receiving cavity 903 can be machined on the side wall of the second tube 902 facing the button cover 16. The slotted end of the button cover 16 is inserted into the receiving cavity 903 to avoid interference with the movement of the button cover 16. The beneficial effects of this technical solution are that, by designing the button cover 16, on the one hand, the end face area of ​​the button cover 16 is larger than that of the pressing rod 11, and when it is connected to the button piece 10 with adhesive tape, the contact area is larger, making the connection relatively stable. Secondly, setting the pressing rod 11 on the button cover 16 is convenient for processing. In actual use, it is preferable to integrally form the pressing rod 11 and the button cover 16.

[0049] In another technical solution, a second sealing ring 13 is provided on the outer circumferential wall of the button cover 16. The second sealing ring 13 is located on the side of the second tube 902 away from the first tube 901, and the outer circumferential wall of the second sealing ring 13 is tightly fitted with the inner circumferential wall of the rotary handle 2. Specifically, an annular groove (not shown in the figure) is provided on the outer circumferential wall of the button cover 16, and the second sealing ring 13 is provided in the annular groove. The second sealing ring 13 is tightly fitted with the inner circumferential wall of the rotary handle 2. The beneficial effect of this technical solution is that by setting the second sealing ring 13, water can be prevented from seeping into the rotary handle 2 and the housing 1 from the gap between the button cover 16 and the rotary handle 2, thereby protecting the internal electronic components, such as the first PCB board 6, the ring encoder 8, and the spring-loaded electronic micro switch 7, avoiding short circuits and damage caused by water seepage, thereby extending the service life of the entire electronic handle structure and ensuring its normal and reliable operation in the humid environment of the kitchen.

[0050] In another technical solution, a horizontal plate 17 is horizontally connected between a pair of mounting plates 14. A pair of shelves 18 are provided on the horizontal plate 17, and a second PCB board 19 for mounting functional lights is placed on the shelves 18. An auxiliary bracket 20 is also included, which is mounted on the horizontal plate 17 and has multiple functional light mounting holes 21 located above the functional PCB board. Multiple function icons are provided on the outer wall of the housing 1, and each function icon corresponds one-to-one with a functional light mounting hole 21. Specifically, a horizontal plate 17 is provided between the pair of mounting plates 14. The horizontal plate 17 is connected to a pair of mounting plates 14 at both ends. A pair of shelves 18 are provided on the horizontal plate 17, and a second PCB board 19 is mounted on the shelves 18. The second PCB board 19 is used to mount function lights, and the function lights are soldered to the second PCB board 19. Function icons are provided on the outer casing 1 corresponding to the function lights. These function icons can be printed on the outer casing 1 using molding or laser printing. The function icons can be symbols representing different functions, such as room temperature water icons, hot water icons, switch icons, etc., designed according to actual needs. When the function light is on, the user can clearly see the illuminated area on the outer casing 1. The system includes function icons to provide a clearer understanding of the current status of the faucet; furthermore, it also includes an auxiliary support 20, which includes a pair of legs and a frame mounted on the legs. The legs are positioned on either side of a pair of supports 18. The frame has multiple function light mounting holes 21 located above the second PCB board 19. The outer casing 1 has multiple function icons that correspond one-to-one with the function light mounting holes 21. When multiple function lights are soldered onto the second PCB board 19, the lights are inserted or arranged in the corresponding function light mounting holes 21, with the light-emitting end of the light close to the corresponding function light mounting hole 21. The corresponding function icons are provided for users to view intuitively. The beneficial effects of adopting this technical solution are that by setting up the horizontal plate 17, the shelf 18, the second PCB board 19, the auxiliary bracket 20, the function light mounting hole 21, and the function icons, a user can intuitively understand the current status of the faucet. By designing the auxiliary bracket 20 and the function light mounting hole 21, the function lights can be confined within the function light mounting hole 21, ensuring that the function lights and their corresponding function light icons are accurately matched. This avoids the situation where the function lights are displaced under external force or external factors without any restraint, resulting in the function lights and function icons not matching.

[0051] In another technical solution, the button lever is snapped into the inner wall of the ring encoder 8, so that the end of the button lever near the first PCB board 6 slides along the inner wall of the ring encoder 8. Specifically, the surface of the end of the pressing rod 11 facing the first PCB board 6 is machined with multiple slots. In the ring encoder 8, the inner wall of the stator 801, which is coaxially disposed in the rotor 802, is machined with multiple protrusions that are adapted to the slots (the protrusions are the snap-in structures). The protrusions are inserted into the corresponding slots. When an external force presses the button piece 10 and drives the pressing rod 11 to move, the pressing rod 11 moves along the protrusions to accurately press the spring-loaded electronic micro switch 7. In actual use, the number of slots and protrusions is preferably multiple, such as four. The design of multiple slots and protrusions can further improve the accuracy of the pressing rod 11 when it moves.

[0052] In another technical solution, the button piece 10 is a CD-patterned decorative cover. The design of the CD-patterned decorative cover can enhance the feel and give the user a delicate and comfortable feeling during operation, thereby improving the user experience. It is also easy to process, wear-resistant, and aesthetically pleasing.

[0053] The number of devices and processing scale described herein are for the purpose of simplifying the description of this utility model.
