Description

Technical Field

[0001] This utility model relates to the field of household appliances, and in particular to a food processing machine. Background Technology

[0002] To meet users' processing needs, existing food processing machines typically have multiple processing functions. Corresponding to these functions, these machines usually have function buttons for users to select. These function buttons are usually located on the outside of the main unit, and users access the corresponding functions by operating these buttons. However, this approach has the following technical problems: Setting up traditional buttons and corresponding indicators requires buttons to correspond to specific functions, which becomes difficult to arrange effectively on the outside of the main unit when there are many functions; alternatively, selecting functions via buttons requires multiple operations when selecting later functions, increasing the number of steps for the user and also increasing the risk of accidental activation.

[0003] As an improvement, an existing technical solution employs an encoder and an operating knob. For example, Chinese Patent No. CN201920690074.0 discloses a food processing machine, including a base with a built-in motor and a mixing cup mounted above the base. An encoder is mounted on the control panel, surrounding the switch buttons. The encoder includes a fixed ring and a rotating ring. An indicator light, electrically connected to the control panel, is located between the control panel and the buttons. The user operates the knob to rotate the encoder and select the corresponding function; the indicator light shows whether the food processing machine is in the activated state.

[0004] The above solution utilizes the rotation of an encoder, reducing the number of function settings, and the rotation operation is more convenient and faster than buttons. However, this solution still has the following shortcomings: since the indicator light can only show whether the food processor is on, the user cannot accurately determine the processing status of the food processor, especially when handling long cooking functions, which will greatly reduce the user experience. Adding a display screen and other functional modules would increase the structural complexity and cost of the food processor. Summary of the Invention

[0005] The purpose of this utility model is to provide a food processing machine that is easy to operate. Based on the existing easy-to-operate knobs and encoders, it solves the technical problems of existing food processing machines having single functions, structural complexity caused by the need for additional display structures, and poor display effects. In this way, it provides a food processing machine that integrates operation and display functions, is easy to operate, and has a good display effect.

[0006] To solve the above-mentioned technical problems, this utility model provides a convenient food processing machine, including a main unit and processing components. The main unit includes a housing with mounting holes and a knob assembly disposed at the mounting holes. The knob assembly includes: a knob bracket disposed at the mounting holes and fixed to the inner wall of the housing; a control board mounted on the knob bracket, with a button and an encoder surrounding the button on the side facing the mounting holes; a display module including a button bracket, a display board, a display bracket, and a display panel arranged sequentially from the inside to the outside. The button bracket is circumferentially limited and slidably disposed along the axial direction to trigger the button. The display board is electrically connected to the control board and has a display unit on the side facing outwards. The display bracket is attached to the outside of the display board and has independent light-transmitting slots to separate the display units. The display panel is attached to the outside of the display bracket to block the light-transmitting slots; and a knob sleeved on the outer periphery of the display module and connected to the encoder to operate the encoder.

[0007] Preferably, the knob assembly further includes an indicator component, which includes an indicator light disposed inside the housing and electrically connected to the control board. The housing has an indicator position that displays the corresponding function when the indicator light is lit.

[0008] Preferably, the indicator component further includes an opaque focusing bracket and a light-transmitting lampshade. The focusing bracket is fitted over the indicator light and has a light-transmitting hole, and the lampshade is positioned at the top of the light-transmitting hole and abuts against the inner wall of the housing.

[0009] Preferably, the housing is further provided with an indicator hole forming an indicator position, and the lampshade is provided with an indicator post inserted into the indicator hole.

[0010] Preferably, multiple indicator lights are provided and disposed on the control panel and surrounding the outer periphery of the encoder, and the focusing bracket is provided with a light-transmitting hole corresponding to the indicator light and the focusing bracket is integrally formed with the knob bracket.

[0011] Preferably, the display module further includes a display film sandwiched between the display bracket and the display panel, the display film being adhered to the display bracket.

[0012] Preferably, the encoder includes a fixed ring on the inner circumference and a rotating ring on the outer circumference, the button bracket is inserted into the fixed ring, and the button bracket and the fixed ring are provided with mutually cooperating grooves and protrusions.

[0013] Preferably, the knob assembly further includes a spring for pushing the button bracket, the spring being sleeved around the outer periphery of the button.

[0014] Preferably, the encoder includes a fixed ring on the inner circumference and a rotating ring on the outer circumference, the knob is sleeved on the outer circumference of the rotating ring, and a buckle is provided between the knob and the rotating ring to cooperate with each other.

[0015] Preferably, the knob sidewall is further provided with an outwardly extending baffle, which is located inside the housing and covers the mounting hole.

[0016] After adopting the above technical solution, this utility model has the following technical advantages.

[0017] 1. The food processing machine of this utility model directly sets a knob assembly at the mounting hole of the machine housing. Compared with the prior art, the knob assembly includes a knob bracket, a control board, a display module, and a knob. The control board, display module, and knob are mounted on the knob bracket, and then the knob bracket and the machine housing are used for installation, making the installation between the knob assembly and the machine housing convenient and the structure simple. Furthermore, the display module is sleeved inside the knob. The display module includes a display panel, a display bracket, and a display panel. The display panel displays the corresponding functions and instructions during processing according to the actual functions and processing process. The display bracket and display panel protect the display panel and make the display... The display panel offers superior visibility, allowing users to intuitively understand the current working status and progress of the food processor. Specifically, the display module, positioned in the center of the knob, is prevented from rotating circumferentially; users can only rotate the knob and press the display module, ensuring the display content remains in a preset positive position for easy observation. The knob is directly fitted around the display module; users operate the knob to activate the encoder on the control board to select functions, viewing the selection in real-time on the display module and confirming the function by pressing the display module, making operation more convenient. Furthermore, the centralized structure reduces the installation requirements of the main unit; the casing only needs mounting holes, ensuring structural stability and reliability, and effectively reducing the risk of water ingress into the main unit.

[0018] 2. Furthermore, the food processor also includes an indicator component, which includes an indicator light disposed within the housing. The indicator light is electrically connected to the control board to display the corresponding information under the control of the control board. A corresponding function indicator is provided on the outside of the housing. This ensures that when the food processor is not in operation or when no corresponding function is selected, the corresponding function is not displayed, or only the status of the housing itself is displayed. When the user selects a corresponding function, the indicator light illuminates, and the corresponding function is displayed on the housing, allowing the user to more intuitively observe the currently selected function. In particular, frequently used functions of the food processor can be set to be displayed on the indicator on the housing, while functions that are used less frequently by the user are only displayed through the display module, making user operation more convenient.

[0019] 3. Further, an opaque focusing bracket and a translucent lampshade are provided. The opaque focusing bracket is fitted over the indicator light to prevent light leakage and to concentrate the light onto the indicator position on the housing. The translucent lampshade guides the light to the corresponding indicator position, ensuring both concentrated light and effective indication without increasing the indicator's brightness. The lampshade abuts against the inner wall of the housing, further preventing light leakage and ensuring structural stability and reliability between the indicator component and the housing.

[0020] 4. The housing is provided with corresponding indicator holes, and the lampshade is provided with indicator posts inserted into the indicator holes. The indicator holes can penetrate the housing, allowing the indicator posts to be directly exposed, providing a more intuitive indication of the corresponding function. Alternatively, the indicator light can not penetrate the housing; instead, a blind hole can be provided on the inner wall of the housing, with the indicator light inserted into the indicator hole. When no function is selected, the exterior of the housing remains unchanged; only when the indicator light is lit does the corresponding indicator position illuminate through the blind hole, thus improving the overall display effect of the host. These differences can meet different host requirements. For example, when using a host with a metal housing, the light from the indicator light cannot penetrate the housing at all, and usually only a penetrating indicator hole can be provided. However, when using a plastic housing that allows partial light penetration, a blind hole can be provided, allowing the indicator light to pass through the housing and display the corresponding indicator position.

[0021] 5. The indicator lights are directly mounted on the control panel, reducing the need for separate indicator light installations. Multiple indicator lights surround the encoder, and the focusing bracket has corresponding light-transmitting holes for each indicator light. Furthermore, the focusing bracket and the knob bracket are integrally formed, ensuring synchronized installation of the encoder and indicator lights when the control panel and knob bracket are in place. Moreover, with multiple indicator lights directly mounted on the control panel and corresponding indicator positions on the machine housing, different indicator positions can be used to meet various indication needs for food processing machines with different functions, thus improving versatility.

[0022] 6. Although the display bracket and the display panel can isolate the functional display areas on the display panel, different products may have different installation positions between the display bracket and the display panel. Therefore, a perfect fit between the universal display panel and the display bracket cannot be guaranteed, resulting in a risk of light leakage between them. Further, a display film is provided and adhered to the display bracket. The display film effectively covers the light-transmitting grooves of the display bracket, preventing light leakage between the grooves and thus ensuring the display effect of the display module.

[0023] 7. The encoder directly sets a fixed ring and a rotating ring on the control panel. The fixed ring is used to install the button, and the fixed ring and the button are provided with mutually cooperating grooves and protrusions to prevent the button from rotating circumferentially and to allow the button to be easily operated to slide axially to push and trigger the button. This makes it convenient for users to select a function by rotating the encoder and then directly press the display component to determine the selected function, making the operation more convenient.

[0024] 8. Further, a spring is provided to push the button bracket to ensure that the display component can return to its original position in a timely manner after the button is triggered. The spring sleeved on the outer periphery of the button can make the reverse force on the button uniform, and avoid the button and the knob bracket from rubbing against each other when subjected to local force, thus preventing the button from failing to reset effectively.

[0025] 9. A locking buckle is directly provided between the knob and the rotating ring to cooperate with each other. When the knob is sleeved on the outer circumference of the rotating ring, it can be directly installed in place, making the installation more convenient, stable and reliable, and effectively ensuring the operation effect.

[0026] 10. Further, an outwardly extending baffle is provided on the side wall of the knob, and the baffle is located inside the housing and covers the mounting hole, so as to effectively seal the mounting hole and prevent water or dust from entering through the mounting hole, thus ensuring that the food processing machine is safer.

[0045] like Figures 1-10As shown, this application provides a convenient food processor, which includes a main unit 900 and processing components (not shown). The main unit 900 and the processing components can be integrated, for example, the food processor can be a rice cooker or an integrated food processor with the processing components directly installed in the main unit; or, the main unit 900 and the processing components can be separate, for example, the food processor can be a separate blender, juicer, water pot, tea beverage equipment for making tea and milk tea, etc. Preferably, the processing assembly contains a processing component, and the main unit 900 contains a motor that drives the processing component to rotate, thereby processing the food placed in the processing assembly; or, the main unit 900 and the processing assembly can be provided with an electrical coupler, the processing assembly is provided with a heating module, and the main unit 900 supplies power to the processing assembly to make the heating module work to process the food placed in the processing assembly. For general food processing machines, an operation module is usually required to select the corresponding function. Therefore, the specific form of the food processing machine is not limited. Food processing machines that include the knob assembly described in this application are all covered by the protection scope of this application.

[0046] The main unit 900 includes a housing 901 and a knob assembly. The housing 901 has a mounting hole 910, and the knob assembly is disposed at the mounting hole and at least partially exposed outside the housing 901. The knob assembly includes a knob bracket 1, a control board 2, a display module 3, and a knob 4. The control board 2, display module 3, and knob 4 are mounted on the knob bracket 1, which is fixed inside the housing 901 and located at the mounting hole 910, so that the knob 4 is exposed outside the housing 901. The control board 2 is located inside the housing 901. A button 21 and an encoder 6 are provided on the side of the control board 2 facing the mounting hole (i.e., the outside of the main unit 900), and the encoder 6 surrounds the outer periphery of the button 21.

[0047] The display module 3 includes a button bracket 31, a display panel 32, a display support 33, and a display panel 35 arranged sequentially from the inside to the outside (i.e., from the inside to the outside of the host 900). The display module is assembled with the knob bracket 1 and the control board 2. The button bracket 31 is slidably disposed along the axial direction of the display module 3 and can trigger the button 21. Simultaneously, the button bracket 31 is circumferentially limited and cannot rotate circumferentially. The user can trigger the button 21 by pressing the display panel 35 and causing the button bracket 31 to move. The display panel 32 is electrically connected to the control board 2, and a display unit 321 is provided on the outward-facing side of the display panel 32. The display unit 321 can be a display screen or a digital tube. When the user operates the knob assembly, the display unit 321 displays the corresponding function. The display support 33 is attached to the outer side of the display panel 32, and the display support 33 has a light-transmitting groove 331 corresponding to the display unit 321. The user can view the content displayed by the display unit 321 through the light-transmitting groove 331. When the display unit 321 is a display screen, the light-transmitting groove 331 can be configured to completely transmit light through the entire display unit 321; when the display unit 321 is a digital tube, multiple light-transmitting grooves 331 are configured and are independent of each other, separating the multiple digital tubes to avoid interference between them when they are lit separately. The display panel 35 is attached to the outside of the display bracket 33 to block the light-transmitting grooves 331, so that the display module displays more uniformly and the display effect is better.

[0048] The inner side of the knob 4 is connected to the encoder 6, and the outer side is sleeved on the outer periphery of the display module. The user can operate the knob 4 to drive the encoder 6 to work, so that the food processing machine can select the corresponding function and display it on the display module. The user can further press the display module to confirm the corresponding function.

[0049] Compared to existing traditional encoder and indicator light structures, this application integrates a display module in the central area of ​​the knob and encoder. Firstly, the combination of the knob and encoder offers greater convenience and speed compared to traditional function selection, allowing for the addition or removal of function selections based on settings, making it more intelligent and convenient to operate. Secondly, when the user operates the knob, the display module within it promptly displays the corresponding function, allowing the user to confirm the selected function by directly pressing the display module, which is quick and easy. Furthermore, when executing a function, the display module provides a more intuitive display of the current working progress, such as the current working time and temperature, enabling the user to directly observe and understand the processing status, thus facilitating the use of the food processor. Moreover, the centralized structure and function of the knob assembly allow for quicker and more efficient assembly via a centralized knob bracket, while also ensuring the safety and reliability of the knob assembly.

[0050] Specifically, this utility model provides a convenient food processor. Preferably, the knob assembly further includes an indicator component 5, which, together with the display module 3, displays the corresponding functions. Preferably, multiple indicator components 5 can be provided, displaying functions frequently used by the user. Furthermore, the food processor preferably defaults to frequently used functions upon startup and displays these functions externally to the main unit 900 via the indicator components 5. Users can directly press the display module 3 to select the corresponding function without needing to operate the knob. Of course, users can also operate the knob 4 to select frequently used functions and further display more less frequently used functions via the display module, thereby expanding the function selection of the food processor and making it more convenient for users.

[0051] Preferred, such as Figures 2-6As shown, the encoder 6 includes a fixed ring 62 located on the inner circumference and a rotating ring 61 located on the outer circumference. The rotating ring 61 and the fixed ring 62 are arranged adjacent to each other. The button 21 is located inside the fixed ring 62, preferably at the center of the fixed ring 62. The knob 4 has a knob mounting hole 40 extending axially along the rotation center of the knob 4. The knob mounting hole 40 passes through the knob 4, and the display module 3 is located at the knob mounting hole 40. The knob 4 includes a knob operating ring 41, a baffle 42, and a knob fixing ring 43 connected to each other. The knob operating ring 41 extends out of the main unit through the mounting hole 910. The outer circumference of the knob operating ring 41 is provided with anti-slip ribs 411, which provide anti-slip function when the user operates the knob 4. The baffle 42 extends radially outward along the outer side wall of the knob 4. When the knob assembly is installed inside the mounting hole 910, the baffle 42 blocks the mounting hole 910. The knob fixing ring 43 is sleeved on the outer periphery of the rotating ring 61, and the inner end of the knob fixing ring 43 is provided with a knob buckle 44. Correspondingly, the rotating ring 61 is provided with a rotating ring buckle 611. When the knob 4 is installed on the encoder 6, the knob buckle 44 and the rotating ring buckle 611 engage with each other to ensure that the rotating ring 61 can be rotated when the user operates the knob 4. Preferably, the rotating ring 61 is provided with a rotating ring groove 612 at the rotating ring buckle 611, and the rotating ring buckle 611 is disposed at the rotating ring groove 612. Understandably, in order to better ensure the cooperation between the knob 4 and the rotating ring 61, the knob 4 and the rotating ring 61 are provided with grooves and protrusions that engage with each other, so as to ensure effective driving between the knob 4 and the rotating ring 61.

[0052] Preferably, the knob bracket 1 includes a bracket body 11, with a bracket mounting hole 12 in the central area of ​​the bracket body 11 and a plurality of bracket fixing posts 13 on the outer periphery of the bracket mounting hole 12. The bracket body 11 has a bracket limiting rib 14, a bracket buckle 15 and a bracket positioning post 16 on the side facing the control panel 2. The control panel 2 is fixedly connected to the knob bracket 1 through the bracket limiting rib 14, the bracket buckle 15 and the bracket positioning post 16. The knob bracket 1 also includes a connecting rib 17 connecting the bracket fixing posts 13. Preferably, the inner side of the housing 901 is provided with a housing mounting post 911, and the knob bracket 1 is further fixedly connected to the housing mounting post 911 through the bracket fixing post 13 to fix the knob assembly inside the host 900.

[0053] like Figures 4-8As shown, the display module 3 also includes a display film 34 sandwiched between the display bracket 33 and the display panel 35. Specifically, the button bracket 31 is inserted into the fixing ring 62 to be fixedly connected to the control board 2. The button bracket 31 is provided with a button buckle 311. The inner side of the fixing ring 62 is provided with a buckle or slot (not shown) that cooperates with the button buckle 311. The outer side wall of the button bracket 31 is also provided with a button protrusion 312. The inner side wall of the fixing ring 62 is provided with a corresponding fixing ring groove 621. The cooperation of the button buckle 311 and the slot, and the button protrusion 312 and the fixing ring groove 621, prevents the button bracket 31 from rotating circumferentially, but allows the button bracket 31 to move axially along the fixing ring 62, so that the button post 315 located at the rear end of the button bracket 31 can push and trigger the button 21. Preferably, the knob assembly further includes a spring 36 for pushing the button bracket 31. One end of the spring 36 abuts against the button bracket 31 and is sleeved on the outer periphery of the button post 315, and the other end abuts against the control plate 2 and is sleeved on the outer periphery of the button 21. The button bracket 31 is axially limited by the cooperation of the button latch 311 and the slot to prevent the button bracket 31 from falling off. The spring 36 pushes the button bracket 31 to reset after the user presses it, ensuring that the button bracket 31 is always in the predetermined position. The button bracket 31 has a button ring rib 313 at the other end opposite to the button latch 311, and the button ring rib 313 is provided with a button fixing hole 314.

[0054] Preferably, the display unit 321 is a multi-digit digital tube disposed on the outside of the display panel 32. The display bracket 33 has a light-transmitting groove 331 that cooperates with the multi-digit digital tube. The light-transmitting groove 331 is arranged one-to-one with the digital tube to avoid mutual interference of the light from the digital tubes, which would affect the user's observation. The display film 34 is pasted on the outside of the display bracket 33 to close the light-transmitting groove 331. Preferably, the display film 34 is made of a light-transmitting material, so that the user can better observe the display content of the display panel 32 from the outside. The display panel 35 is located on the outermost side of the display module 3. The outer surface of the display panel 35 is also provided with a display area 351, which allows the user to easily observe the display status of the display area 351 and intuitively understand the currently selected function.

[0055] The sidewall of the display panel 32 is provided with a display panel notch 322 corresponding to the button fixing hole 314. The display bracket 33 is provided with a display bracket fixing post 333 corresponding to the button fixing hole 314. The display module is provided with a first screw 371, which passes through the button fixing hole 314, the display panel notch 322, and the button fixing hole 314 to fix the display bracket 33 and the display panel 32 to the button bracket 31. The display panel 32 is also provided with a display panel fixing hole 323. The display bracket 33 is provided with a corresponding display bracket mounting hole 332. The display mask 34 is provided with a corresponding mask mounting hole 341. The display panel 35 is provided with a corresponding display panel fixing post 352. The display module 35 is provided with a second screw 372, which passes through the display panel fixing hole 323, the display bracket mounting hole 332, and the mask mounting hole 341 in sequence and locks with the display panel fixing post 352. Thus, the display module 3 is assembled, and then, through the button bracket 31 and the fixing ring 62, the display module 3 is installed in the knob mounting hole 40 of the knob 4. The user operates the knob 4 to adjust and select the functions of the food processor, and presses the display module to confirm the selected function. During operation, the display module can also display the current working status of the function in real time, allowing the user to more intuitively understand the current work progress, making it more convenient for the user to operate and use the food processor.

[0056] like Figures 5-10 As shown, the indicator assembly of the housing 901 includes an indicator light 53, a focusing bracket 52 fitted over the indicator light 53, and a lampshade 51 located between the focusing bracket 52 and the housing 901. An indicator position 54 corresponding to the indicator light 53 is also provided on the outer side. Preferably, the indicator light 53 is mounted on the control panel 2 and illuminates according to the control of the control panel 2. The focusing bracket 52 is made of an opaque material and has a light-transmitting hole 521. Preferably, the focusing bracket 52 is integrally formed with the knob bracket 1. When the knob bracket 1 and the control panel 2 are assembled, the focusing bracket 52 is fitted over the indicator light 53, and the indicator light 53 extends into the light-transmitting hole 521. The lampshade 51 is located at the opening end of the light-transmitting hole 521 and is made of a light-transmitting material. Thus, the light from the indicator light 53 passes through the light-transmitting hole 521 and then through the lampshade 51, illuminating the inner wall of the housing 901. Preferably, the inner wall of the housing 901 is provided with an indicator hole 912 corresponding to the indicator position 54, and the lampshade 51 is provided with an indicator post 511 inserted into the indicator hole 912.

[0057] The indicator hole 912 can penetrate the housing 901, or the indicator hole 912 can not penetrate the housing 901. For example, when the housing 901 is made of an opaque material such as stainless steel, the indicator hole 912 penetrates the housing 901, allowing the indicator post 511 to protrude and the light from the indicator light 53 to leak out. When the housing 901 is made of plastic and can partially transmit light, the indicator hole 912 can be set as a non-penetrating blind hole. In areas where the indicator hole 912 is not provided, the housing can block the light from the indicator light 53, while in areas where the indicator post 511 extends, the housing 901 is insufficient to block the light from the indicator light 53. Thus, the indicator light 53 can illuminate the area of ​​the indicator position 54.

[0058] The housing 901 is further provided with an outer positioning ring 913 and an inner positioning ring 914 on the inner side corresponding to the indicator position 54. The focusing bracket 52 is inserted into the outer positioning ring 913, and the lampshade 51 is clamped between the focusing bracket 52 and the housing 901, so that the lampshade 51 abuts against the inner positioning ring 914. In this way, the focusing bracket 52 and the lampshade 51 are stably and reliably set on the inner wall of the housing 901.

[0059] The indicator lights 53, spotlight brackets 52, and lampshades 51 can be configured in multiples according to the needs of the food processor. For example, in this embodiment, four indicator lights 53, spotlight brackets 52, and lampshades 51 are configured and surround the outer periphery of the encoder 6. Correspondingly, the same number of indicator positions 54 on the main unit are configured one-to-one. When the user operates the food processor, it usually jumps to the preferred function immediately upon powering on. At this time, the user can directly press the display module to trigger the button to start the corresponding function without operating the knob and encoder; or, the user can select the corresponding function by rotating the knob. The frequently used functions can be displayed on the indicator positions for easy selection and confirmation by the user; when the function selected by the user is not displayed on the indicator positions, it can also be displayed through the display module, thus increasing the function selection of the food processor. Furthermore, during the operation of the food processing machine, the display module can also display the processing status of the current processing program in a timely manner, such as the current processing temperature and processing time, so that users can directly observe and understand the required status; the display module can also remind users of information such as ingredients that need to be added during the processing, based on the current processing program.

[0060] Using the food processing machine described in this application, an integrated, one-piece knob assembly allows users to control the machine by operating the knob and display module in the same location, eliminating the need to select multiple areas of the machine and making it more convenient. During operation, the display module and indicator assembly provide timely feedback on the machine's current operating status, facilitating user operation and access to relevant information, thus enhancing the user experience.

[0061] Understandably, the food processing machine may only have a display module and not an indicator component. For example, the display module may directly display the corresponding processing information on a screen, allowing the user to intuitively observe the selected function and dynamic information of the processing process through the screen.

[0062] Understandably, the indicator component may be configured with an integrated focusing bracket and lampshade, and a light-transmitting hole for light transmission in the central area.

[0063] It is understood that the indicator component can be set separately and fixed inside the housing. For example, the indicator component includes a separately set indicator light panel, a separately set spotlight bracket and lampshade, etc., and is fixedly set on the inner wall of the housing.

[0064] Understandably, an elastic structure such as an elastic silicone pad or elastic sheet can be provided between the button bracket and the control board to push the button bracket to reset. Alternatively, mutually repelling magnetic components can be provided between the button bracket and the control board; or even, a closed space can be provided between the button bracket and the control board, utilizing the air pressure within the closed space to achieve button bracket reset.

[0065] Understandably, the display module can be attached to the display bracket by directly applying a soft material to the back of the display panel, without applying the display film.

[0066] Understandably, the display module can be directly fixed to the control board without the fixing ring.

[0067] Understandably, the main unit is also provided with a seal at the mounting hole, which is clamped between the housing and the knob, to prevent water from entering through the mounting hole.

[0068] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model. All equivalent changes and modifications made in accordance with the present utility model are covered by the scope of the claims of the present utility model, and will not be listed here.
