Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a dial switch knob structure and stove. Background Technology

[0002] A DIP switch, also known as a DIP code switch, is generally used in the control circuits of household appliances such as stoves, barbecue grills, and microwave ovens, where the switch status and power level are adjusted by manually toggling the switch. It can also be combined with light sources to control and adjust parameters such as light brightness and color.

[0003] Currently available rotary dial switches generally suffer from stiff operation and limited functionality. Traditional knob designs often require complex transmission mechanisms to achieve combined rotation and pressing operations, resulting in cumbersome assembly processes and a high failure rate. Particularly in stove applications, most existing gas valve knobs only offer single mechanical control functions, lacking visual feedback, making it difficult for users to accurately determine the knob's position in dim lighting conditions.

[0004] In addition, traditional knob structures with light displays have the problem of loose fit between the light-emitting unit and the rotating mechanism, which can easily lead to delays or misalignments in the light display, thus affecting the user experience. Utility Model Content

[0005] To address the technical deficiencies mentioned in the background section, the present invention aims to provide a rotary dial structure and stove. By setting a linkage component between the dial body and the rotary dial, precise linkage between rotation operation and light display can be achieved. This makes the dial structure easy to switch on and off and adjust in dimly lit environments, improving not only the product's appearance but also the user experience.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A dial switch knob structure includes a knob body, a dial switch that rotatably engages with the knob body, and a linkage assembly connecting the knob body and the dial switch. The linkage assembly includes a rotating sleeve and a connecting shaft. The rotating sleeve is a cylindrical structure with one open end, and the other end of the rotating sleeve has a through hole adapted to the connecting shaft. Multiple elastic buckles are provided on the inner circumferential surface of the rotating sleeve. The elastic buckles are engaged with the dial switch, and a limiting platform is provided between two adjacent elastic buckles. The limiting platform is connected to the peripheral wall of the rotating sleeve and protrudes from the inner circumferential surface of the rotating sleeve, and the limiting platform and the rotating sleeve are integrally formed. The rotating sleeve is engaged with the dial switch through the elastic buckles and the limiting platform, and is circumferentially fixed. One end of the connecting shaft passes through the through hole and extends into the dial switch, and the other end is connected to the knob body. The connecting shaft moves relative to the dial switch along the axial direction of the knob body, so that the rotating sleeve can rotate together with the dial switch as the knob body rotates.

[0008] Preferably, the peripheral wall of the rotating sleeve is provided with relief grooves on both sides corresponding to the elastic buckle. The relief grooves are M-shaped and the periphery of the relief grooves are connected to the elastic buckle.

[0009] Preferably, the knob body has an open cavity at the bottom, a rotating shaft is provided in the cavity, a non-circular insertion hole is provided in the rotating shaft, a keyway is provided on the circumferential surface of the insertion hole, and the rotating shaft is connected to the connecting shaft by a key.

[0010] Preferably, the dial switch has a central hole for the rotating shaft to pass through, and the dial switch has an annular groove around the central hole. The knob body is inserted into the annular groove and rotates relative to the dial switch through the rotating shaft.

[0011] Preferably, the dial switch includes a base, an LED light panel, a rotary dial, and a cover plate stacked sequentially from bottom to top. The base has a positioning protrusion arranged circumferentially around the central hole. The positioning protrusion is perpendicular to the base, and one end of the positioning protrusion extends into the rotary dial. The LED light panel is detachably connected to the base, and multiple LED light sources are distributed in a circumferential array on the LED light panel. The bottom end of the rotary dial is provided with conductive pins, which are inserted into and electrically connected to the LED light panel. The cover plate covers the outside of the base, and the cover plate has a light-transmitting part at the position corresponding to the LED light source.

[0012] Preferably, the base is further provided with a positioning post, the LED light panel has mounting holes corresponding to the positioning post, and the cover plate is fixedly connected to the positioning post by screws passing through the mounting holes.

[0013] Preferably, the inner surface of the rotary dial is provided with a plurality of positioning grooves distributed circumferentially, and a limiting rib is provided in the positioning groove corresponding to the position of the positioning protrusion, and the limiting rib is engaged with the positioning protrusion; the outer surface of the rotary dial is provided with a limiting groove adapted to the limiting platform and the elastic buckle, and the limiting groove is distributed in an up-and-down staggered interval.

[0014] A stove includes a stove body and a dial switch knob structure. A gas valve is provided in the stove body. The gas valve is externally connected to a gas pipeline, and a valve shaft is connected to the gas valve. The valve shaft passes through the dial switch and is connected to a connecting shaft.

[0015] In summary, the beneficial effects of this utility model are as follows:

[0016] When the dial switch knob structure of this utility model is applied to a stove, pressing and rotating the knob body controls the valve shaft of the gas valve via the control shaft and linkage components, allowing the valve shaft to extend, retract, and rotate, thereby opening the gas valve and adjusting the flame. As the knob body rotates, it drives the rotating sleeve to rotate, causing the dial switch mounted on the sleeve to rotate as well, triggering the light-emitting unit within the dial switch to achieve a light display effect. This not only improves the product's appearance but also makes the knob structure easy to use in dimly lit environments, enhancing the user experience. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1-9 The present invention provides a more detailed description of an embodiment of a dial switch knob structure and a stove.

[0032] Example 1

[0033] A rotary switch 2 structure, such as Figures 1 to 4 As shown, including

[0034] The knob body 1 has an open cavity 11 at the bottom, a rotating shaft 12 is provided in the cavity 11, a non-circular insertion hole 121 is provided in the rotating shaft 12, and a keyway 122 is provided on the circumferential surface of the insertion hole 121.

[0035] The dial switch 2 has multiple arrayed LED light sources 222 inside. The dial switch 2 is provided with a central hole 4 for passing through the rotating shaft 12, and the dial switch 2 is provided with an annular groove 5 around the central hole 4. The knob body 1 is inserted into the annular groove 5 and rotates relative to the dial switch 2 through the rotating shaft 12.

[0036] Linkage component 3 is connected between knob body 1 and DIP switch 2. Linkage component 3 includes rotating sleeve 31 and connecting shaft 32. Rotating sleeve 31 is connected to DIP switch 2 and is circumferentially fixed so that rotating sleeve 31 can rotate with knob body 1. Connecting shaft 32 is connected to rotating shaft 12 by a key. One end of connecting shaft 32 is inserted into socket 121, and the other end passes through through hole 311 and extends into DIP switch 2 so that connecting shaft 32 can move relative to DIP switch 2 along the axial direction of rotating shaft 12.

[0037] Specifically, the knob body 1 is constructed as a cylindrical shape with a closed top and an open bottom. The knob body 1 consists of a knob cover and a top plate. The outer surface of the knob cover is circumferentially provided with anti-slip threads, and the bottom end of the top plate is provided with a connecting strip. The top plate is attached to the top of the knob cover via the connecting strip. To ensure uniform force distribution when the knob body 1 rotates to activate the dial switch 2, and to maintain structural symmetry, thus facilitating mold processing, the upper end of the rotating shaft 12 is connected to the top wall of the top plate and extends along the axis of the knob body 1. The rotating shaft 12 is a hollow cylindrical structure, and its internal non-circular insertion hole 121 allows the connecting shaft 32 to engage and achieve circumferential fixation. This allows the connecting shaft 32 to rotate when the knob body 1 is rotated, thereby causing the rotating sleeve 31, which engages with the connecting shaft 32, to rotate the dial switch 2. The keyed connection between the non-circular insertion hole 121 of the rotating shaft 12 and the connecting shaft 32 ensures precise transmission of rotational torque, while the axial sliding design of the connecting shaft 32 achieves decoupling control of the pressing and rotating actions. The annular groove 5 of the dial switch 2 and the knob body 1 are nested together to form a stable rotation track. Compared with the traditional knob structure, this utility model realizes the combined functions of pressing and rotating to adjust the flame of a single knob through the linkage component 3, and at the same time utilizes the photoelectric conversion characteristics of the dial switch 2 to form a visual operation guide.

[0038] The process by which the linkage component 3 controls the rotation of the dial switch 2 to adjust the LED light source 222 is as follows: by pressing and rotating the knob body 1, the control shaft 12 and the linkage component 3 are used to control the rotation of the dial switch 2; since the knob body 1 will drive the rotating sleeve 31 to rotate during the rotation, the dial switch 2 installed on the rotating sleeve 31 will rotate together, and trigger the light-emitting unit inside the dial switch 2 to achieve the light display effect; this not only improves the appearance of the product, but also makes the knob structure easy to switch on and off and adjust in dim lighting conditions, thus enhancing the user experience.

[0039] In this embodiment, as Figure 5 , 6 As shown, the dial switch 2 includes a base 21, an LED light panel 22, a rotary dial 23, and a cover plate 24 stacked sequentially from bottom to top. The base 21 has a positioning protrusion 211 arranged around the central hole 4, which is perpendicular to the base 21 and one end of the positioning protrusion 211 extends into the rotary dial 23. The LED light panel 22 is detachably connected to the base 21 and is connected to the LED light source 222. The bottom of the rotary dial 23 is provided with a conductive pin 234, which is inserted into and electrically connected to the LED light panel 22. The cover plate 24 is placed on the outside of the base 21 and has a light-transmitting part 241 at the position corresponding to the LED light source 222.

[0040] Specifically, when the knob body 1 rotates, the positioning protrusion 211 of the base 21 is embedded in the positioning groove 231 of the rotary dial 23 to form a circumferential constraint, ensuring that the rotary dial 23 and the knob rotate synchronously. The conductive pin 234 at the bottom of the rotary dial 23 forms a dynamic electrical connection with the LED light panel 22 during rotation, triggering the on / off state of the corresponding LED light source 222 through different contact points. The rotary dial 23, as the central hub for converting mechanical actions and electrical signals, achieves both stepless adjustment and gear positioning through the elastic contact of the conductive pin 234. The linkage between its physical contacts and the LED light source 222 can be customized according to different application scenarios. The array of LED light sources 222 forms a ring-shaped light strip through the light-transmitting part 241 of the cover plate 24, and its brightness and color changes reflect the current operating gear in real time.

[0041] It is worth noting that the positioning protrusions 211 are preferably three in number, and the vertical nesting design of the positioning protrusions 211 and the rotary dial 23 forms a dual guiding function within a limited space. This ensures precise control of the rotation angle and enhances the torsional strength of the structure through the protrusion segments extending into the rotary dial 23. The plug-in connection between the conductive pins 234 and the LED light board 22 breaks through the limitations of traditional welding processes. While ensuring stable signal transmission, it allows the rotary dial 23 to rotate freely. Combined with the modular design of the LED light board 22, different light source components with different light emission modes or colors can be quickly replaced. The synergistic effect of the LED light source array 222 and the rotary dial 23 ensures that the light display is always synchronized with the knob angle. The light-transmitting part 241 on the cover plate 24 is treated with a frosting process to diffuse the light evenly, maintaining clear visibility even in strong light environments. The snap-fit ​​assembly structure between the base 21 and the cover plate 24 achieves an IP54 protection level while retaining a heat dissipation channel for the light source components.

[0042] It is worth noting that, in order to power the LED light source 222 on the LED light board 22, a conductive wire can be led out from the LED light board 22 and connected to an external power source, or a button battery can be installed inside the substrate to provide power.

[0043] In this embodiment, as Figure 6 As shown, a positioning post 212 is also provided on the base 21, and the LED light panel 22 has a mounting hole 221 corresponding to the positioning post 212. The cover plate 24 is fixedly connected to the positioning post 212 by screws passing through the mounting hole 221.

[0044] Specifically, the positioning post 212 of the base 21 and the mounting hole 221 of the LED light board 22 form a self-correcting system, which automatically eliminates accumulated tolerances during assembly. Furthermore, the sealed cavity formed by the base 21 and the cover plate 24 fixed by screws provides dust and water protection for the internal components. The positioning post 212 and the mounting hole 221 work together to enable the LED light board 22 to be quickly positioned and disassembled for maintenance, significantly improving the maintainability of the components.

[0045] In this embodiment, as Figure 8 As shown, the inner surface of the rotary dial 23 has a plurality of positioning grooves 231 distributed around its circumference. The positioning grooves 231 corresponding to the positions of the positioning protrusions 211 are provided with limiting ribs 232, which are engaged with the positioning protrusions 211. The outer surface of the rotary dial 23 is provided with limiting grooves 233 that are adapted to the limiting platform 313 and the elastic buckle 312. The limiting grooves 233 are distributed in an alternating vertical arrangement.

[0046] Specifically, when installing the rotary dial 23, in order to quickly install it onto the base 21 and prevent it from falling off the base 21, a positioning groove 231 that matches the positioning protrusion 211 is opened on the inner side of the rotary dial 23. Since the end of the positioning protrusion 211 has a hook-shaped structure, a limiting rib 232 is set in the positioning groove 231 so that the positioning protrusion 211 can be engaged with the limiting rib 232, thereby completing the quick positioning and installation of the rotary dial 23. Meanwhile, the rotary dial 23 is also connected to the rotary sleeve 31. Therefore, a limiting groove 233 is provided on the outer surface of the rotary dial 23. The limiting groove 233 is set to an upper and lower staggered structure according to the structure of the rotary sleeve 31, so that the rotary dial 23 can be linked with the rotary sleeve 31. The rotation of the rotary sleeve 31 drives the rotary dial 23 to rotate together, thereby triggering and conducting the LED light source 222, so that its light signal forms a ring-shaped dynamic light effect through the light-transmitting part 241 of the cover plate 24, which intuitively displays the current gear or working status.

[0047] In this embodiment, as Figure 9 As shown, the rotating sleeve 31 is a cylindrical structure with one end open, and the other end of the rotating sleeve 31 has a through hole 311 that is adapted to the connecting shaft 32. The rotating sleeve 31 is provided with multiple elastic buckles 312, which are fastened to the dial switch 2, and a limiting platform 313 is provided between two adjacent elastic buckles 312; the limiting platform 313 is connected to the peripheral wall of the rotating sleeve 31 and protrudes from the inner peripheral surface of the rotating sleeve 31, and the limiting platform 313 and the rotating sleeve 31 are integrally formed.

[0048] Specifically, the flexible fit between the elastic buckle 312 and the limiting groove 233 not only reduces assembly difficulty but also improves the smoothness of operation through deformation buffering. The limiting platform 313 can be located on the inner surface of the peripheral wall of the knob body 1, or on the outer surface of the peripheral wall of the knob body 1, or at other locations. The limiting platform 313 protrudes from the inner surface of the knob body 1. When the knob is applied to the dial switch 2, the rotating sleeve 31 is fitted around the dial switch 2, and the limiting platform 313 can abut against the limiting groove 233 located around the dial switch. When dialing is required, the knob body 1 is rotated, and the limiting platform 313 restrains and drives the dial switch of the dial switch 2 to dial.

[0049] To prevent the elastic latch 312 from having sufficient deformation space when the rotating sleeve 31 rotates around the DIP switch 2, clearance grooves 314 are provided on both sides of the peripheral wall of the rotating sleeve 31 corresponding to the elastic latch 312. The clearance grooves 314 have an M-shaped structure, and their periphery is connected to the elastic latch 312. The M-shaped clearance groove 314 structure not only provides deformation space for the elastic latch 312 to accommodate different assembly tolerances, but also enhances rotational stability through the multi-point contact between the limiting platform 313 and the DIP switch 2.

[0050] In addition, the rotating sleeve 31 in this utility model can be adapted to different dial switch 2 structures, which increases the versatility and compatibility of the product. The rotating sleeve 31 connects the knobs that are adapted to different dial switches 2 in the existing products into one unit through the connection method of elastic buckle 312, which can not only save the cost of mold manufacturing, but also simplify the management of materials in production and warehousing.

[0051] Example 2

[0052] A type of stove, such as Figure 4 , 5 As shown, the furnace body 6 and the rotary structure of the dial switch 2 are included. A gas valve 7 is installed inside the furnace body 6. The gas valve 7 is connected to a gas pipeline 8. A valve shaft 9 is connected to the gas valve 7. The valve shaft 9 passes through the dial switch 2 and is connected to the connecting shaft 32.

[0053] Specifically, when the user presses the knob body 1, the connecting shaft 32 moves axially along the rotating shaft 12, pushing the valve shaft 9 of the gas valve 7 to open the gas passage; when the knob body 1 is rotated, the rotating shaft 12 drives the connecting shaft 32 to rotate synchronously through the key connection, thereby driving the valve shaft 9 to adjust the gas flow to achieve fire control. During this process, the rotational force of the knob body 1 is transmitted to the dial switch 2 through the rotating sleeve 31. The elastic buckles 312 distributed circumferentially on the rotating sleeve 31 form a positioning fit with the limiting groove 233 of the dial switch 2, so that the rotating dial 23 inside the dial switch 2 rotates accordingly, triggering the conduction state of different LED light sources 222 on the LED light panel 22. The light signal forms a ring-shaped dynamic light effect through the light-transmitting part 241 of the cover plate 24, intuitively displaying the current gear or working status.

[0054] It should be noted that the knob structure of this utility model can be applied not only to stoves, but also to other household appliances, including but not limited to ovens, portable gas stoves, or air fryers, which have DIP switches.

[0055] In addition, it is worth mentioning that since the stove in this application embodiment includes the dial switch 2 knob structure of the above embodiment, the stove in this application embodiment has the beneficial effects brought by the dial switch 2 knob structure of the above embodiment.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
