Description

Technical Field

[0001] This invention belongs to the field of gas stove technology, specifically, it relates to a gas stove and its magnetic control knob assembly. Background Technology

[0002] As a non-contact control element, the magnetic control knob achieves rotation adjustment function based on the principle of magnetic induction. Its core advantage lies in avoiding problems such as component wear and dust intrusion caused by physical contact, effectively improving the durability and operational reliability of the component. It is currently widely used in household appliances such as gas stoves, gas water heaters, and range hoods.

[0003] Existing magnetic control knob technology is mostly designed with a single rotation adjustment function as its core, and cannot realize pressing operation. It lacks the ability to perform combined rotation and pressing operations, which makes it difficult to meet the diverse operation needs of complex control scenarios of home appliances, and greatly limits its application scenario expansion and functional adaptability.

[0004] To address the aforementioned technical deficiencies, a magnetic control knob with a press control function has been proposed in related technologies. This magnetic control knob has two magnetic poles of the main magnet arranged horizontally, and is equipped with an infrared sensing module and a magnetic sensing chip to detect the axial displacement change and circumferential rotation angle of the main magnet, thereby realizing independent recognition and signal output of pressing and rotating operations.

[0005] However, this technical solution, which uses an infrared sensing module for pressure detection, has several drawbacks: First, the sensing accuracy of the infrared sensing module is easily affected by factors such as ambient light, oil stains, and dust accumulation. In appliance applications with high levels of oil fumes and dust, such as kitchens, it is prone to problems such as failure to recognize pressure signals and false triggering, reducing the accuracy of operation control. Second, the separate structure of the infrared sensing module and the magnetic sensing chip increases the number of internal components and wiring complexity of the magnetic control knob, which not only increases the overall manufacturing cost but also increases the probability of component failure, hindering mass production and subsequent maintenance. Third, the infrared sensing detection method requires high axial displacement accuracy of the main magnet, necessitating strict control of assembly gaps, which increases the difficulty of the product assembly process. Assembly errors can further affect the recognition effect of pressure operation, making it difficult to balance production efficiency and operational stability.

[0006] In view of this, the present invention is hereby proposed. Summary of the Invention

[0007] The technical problem to be solved by this invention is to overcome at least some of the shortcomings of the prior art and provide a magnetic control knob assembly. By configuring a single sensor to sense the magnetic field changes of the magnet during rotation and sliding operations, the invention can accurately identify rotation and sliding operations. This achieves accurate and stable identification of both rotation and sliding operations with a single sensor, while taking into account the structural simplicity, detection reliability, and production adaptability of the magnetic control knob assembly.

[0024] It should be noted that these accompanying drawings and textual descriptions are not intended to limit the scope of the invention in any way, but rather to illustrate the concept of the invention to those skilled in the art by referring to specific embodiments. Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0026] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are 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.

[0027] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0028] As mentioned earlier, existing magnetic control knobs suffer from increased costs and unstable signals due to the separate sensing elements. Therefore, this invention provides a magnetic control knob assembly, including a fixing part, a knob part, and a sensor. The fixing part has a receiving groove, and the knob part is positioned above the fixing part. The knob part has a sensing magnet with two magnetic poles horizontally symmetrically distributed along a vertical center line. The sensing magnet is located in the receiving groove and rotates and slides within it. The sensor is configured to sense changes in the magnetic field of the sensing magnet during rotation and / or sliding within the receiving groove. This solution uses a single sensor to detect changes in the magnetic field of the magnet during rotation and / or sliding operations, enabling integrated detection and accurate identification of rotation and sliding operations. It achieves accurate and stable identification of both rotation and sliding operations with a single sensor, while maintaining the structural simplicity, detection reliability, and production adaptability of the magnetic control knob assembly. This makes it more suitable for complex home appliance applications with high levels of oil fumes and dust, such as kitchens, improving the overall durability and user experience of the magnetic control knob assembly.

[0029] Figures 1 to 20 A partial structural schematic diagram of a gas stove 1 and its magnetic control knob assembly 100 according to an exemplary embodiment of the present invention is shown. It should be noted that the gas stove 1 includes a control panel 200 facing the user. The connection and positional relationships of the various components of the magnetic control knob assembly 100 are described below, taking a horizontally positioned control panel 200 as an example.

[0030] like Figures 1 to 17 As shown, the magnetic control knob assembly 100 includes a fixing part 10, a knob part 20, and a sensor. The fixing part 10 and the knob part 20 are mounted on the side of the control panel facing the user, while the sensor is mounted on the side of the control panel facing away from the user. The extension direction of the "vertical center line" described in the text is along the normal direction of the control panel. Figure 4 and Figure 5 .

[0031] Specifically, the fixing part 10 is used to be fixedly connected to the control panel of the gas stove. It has a receiving groove. The knob part 20 is essentially the operating part when the user operates the magnetic control knob assembly 100. The knob part 20 can rotate axially relative to the central axis of the fixing part 10. It is located above the fixing part 10. The knob part 20 is provided with a sensing magnet 24. The two magnetic poles of the sensing magnet 24 are horizontally symmetrically distributed along the vertical center line. Figure 11 As shown, the sensing magnet 24 is located in the receiving groove and can rotate and slide up and down in the receiving groove; when the sensing magnet 24 rotates and / or slides in the receiving groove, the magnetic pole arrangement can cause a significant change in the direction and / or magnitude of the surrounding magnetic field. At this time, the sensor can sense the change in the magnetic field, thereby identifying the rotation adjustment and sliding press confirmation of the magnetic control knob assembly 100.

[0032] As an example, the sensor is a magnetic induction sensing component with a Hall chip as its core element.

[0033] In the above solution, the magnetic field signals of the two actions are detected by a single sensor, eliminating the need for an additional infrared module, simplifying the structure and improving anti-interference capabilities.

[0034] In some implementations, such as Figure 2 and Figure 6 As shown, the fixing part 10 includes an inner base 11, which has an inner groove 111 and a first outer groove 112 surrounding the outer side of the inner groove 111. The inner groove 111 forms the receiving groove. The first outer groove 112 has a plurality of mounting slots 113 arranged circumferentially, and a plurality of fixing magnets 17 are correspondingly arranged in each of the mounting slots 113. The two magnetic poles of the fixing magnets 17 are distributed at both ends of the axial direction along the vertical center line. It can be understood that the first outer groove 112 and the inner groove 111 are arranged coaxially to ensure the symmetry of the magnetic field distribution.

[0035] In the above scheme, refer to Figure 19 and 20 As shown, a positioning magnet 321 for engaging with the fixed magnet 17 is provided on the side of the control panel 200 facing away from the user. The positioning magnet 321 and the fixed magnet 17 have opposite magnetic poles. The attraction force between the positioning magnet 321 and the fixed magnet 17 achieves a fixed connection between the fixing part 10 and the control panel 200. In addition, the matching magnetic pole layout of the fixed magnet 17 and the sensing magnet 24 can enhance the recognition of magnetic field changes and improve the detection accuracy of the sensor; the circumferentially uniformly arranged fixed magnets 17 can form a symmetrical magnetic field, avoiding misjudgment caused by the deviation of a single magnetic field; the positioning design of the mounting slot 113 facilitates the batch assembly of the fixed magnets 17 and improves production efficiency.

[0036] Preferably, the fixing part 10 further includes a fixing cover 16, which has a clearance hole. The fixing cover 16 is disposed over the opening of the first outer groove 112, and the clearance hole avoids the receiving groove. This can achieve axial positioning of the fixing magnet 17, preventing the fixing magnet 17 from shifting due to vibration during long-term use and ensuring magnetic field stability. At the same time, the fixing cover 16 can also seal the first outer groove 112 to prevent oil fumes and dust from entering and contaminating the fixing magnet 17, improving the durability of the component. Moreover, the structure is simple and easy to disassemble and maintain later.

[0037] It should be noted that, depending on the application scenario, the fixed magnet 17 and the mounting slot 113 can be evenly spaced 6 to 10 times in the circumferential direction, and this invention does not impose any limitation here.

[0038] Optionally, the inner groove 111 and the first outer groove 112 are integrally formed on the inner base 11. For example, the inner base 11 is made of a light-transmitting plastic material.

[0039] During the assembly process, multiple fixed magnets 17 are embedded one by one into the mounting slots 113 of the first outer groove 112, ensuring that the fixed magnets 17 are tightly fitted to the mounting slots 113 without loosening or displacement. Their magnetic pole directions correspond to the magnetic pole directions of the induction magnet 24, forming a stable initial magnetic field environment. When the induction magnet 24 rotates or slides up and down, the magnetic fields of the two interact to generate a recognizable change signal, which is transmitted to the sensor. After the fixed cover 16 is closed, its lower surface abuts against the upper surface of the fixed magnet 17 to limit its movement, preventing the fixed magnet 17 from axially moving within the first outer groove 112. The diameter of the clearance hole is slightly larger than or equal to the opening size of the receiving slot to ensure that there is no contact interference when the induction magnet 24 moves.

[0040] In some implementations, such as Figure 4 , Figure 5 and 8 As shown, the knob part 20 includes a knob base 21, the knob base 21 is provided with a hollow induction magnet mounting part 211, the induction magnet 24 is fixed in the induction magnet mounting part 211, the induction magnet mounting part 211 is located in the receiving groove and can rotate and slide around the central axis of the receiving groove.

[0041] As an example, the knob base 21 is integrally formed to form the hollow sensing magnet mounting part 211. The sensing magnet 24 is interference-fitted or fixed in the hollow cavity of the sensing magnet mounting part 211 by an adhesive to ensure that the two move synchronously. The sensing magnet mounting part 211 is inserted into the receiving groove and can rotate flexibly around the central axis of the receiving groove and slide up and down along the axial direction.

[0042] Optionally, a limiting rib 214 is provided on the inner side wall of the induction magnet mounting part 211, and the induction magnet 24 is in interference contact with the limiting rib 214.

[0043] Furthermore, the outer side wall of the induction magnet mounting part 211 is provided with a plurality of protruding ridges 212 spaced apart along the circumference, and a recess 213 is naturally formed between two adjacent protruding ridges 212; wherein, the inner wall of the receiving groove has a radially retractable protrusion 122, and as the induction magnet mounting part 211 rotates, the protrusion 122 sequentially forms an insertion engagement with the plurality of recesses 213.

[0044] Specifically, after the sensing magnet mounting part 211 is inserted into the receiving groove, the protrusion 122 abuts against the outer wall of the sensing magnet mounting part 211 under its own elastic action. When the sensing magnet mounting part 211 is rotated, the ridge 212 squeezes the protrusion 122 to make it radially contract. After passing the ridge 212, the protrusion 122 elastically resets and embeds into the recess 213, forming a single insertion fit and completing a gear shift.

[0045] In other words, the protruding ridges 212 and the recessed portions 213 are alternately distributed circumferentially along the induction magnet mounting portion 211 to form a gear positioning structure. When the user rotates the knob portion 20, the protruding portion 122 is engaged with the multiple recessed portions 213 in sequence under the elastic force to realize gear position feedback, so that the user can clearly perceive the change in gear position.

[0046] It should be noted that, depending on the different requirements for gear precision in the application scenario, the number of protrusions 212 can be adaptively set in the circumferential direction, and this invention does not impose any limitations on this.

[0047] In the above solution, the insertion and cooperation of the protrusion 122 and the recess 213 provides the user with clear tactile feedback of the gear position, avoids excessive or insufficient operation due to lack of positioning sense when rotating, and improves the accuracy of operation; the protrusion 122 can extend and retract radially to ensure smooth cooperation and no jamming.

[0048] Preferably, the plurality of recesses 213 extend axially, and as the induction magnet mounting part 211 slides and rotates, the protrusion 122 sequentially forms an interlocking engagement with the plurality of recesses 213; this allows the user to clearly perceive the change in gear position when rotating the knob part 20 while sliding, thereby generating a gear position feel during sliding operation.

[0049] Specifically, the axial extension length of the recess 213 matches the sliding stroke of the induction magnet mounting part 211. When the induction magnet mounting part 211 is slid, the protrusion 122 moves synchronously along the axial direction of the recess 213. During the rotation, it can still be inserted into the recess 213, ensuring stable gear feedback under both sliding and rotating combined actions.

[0050] The above-mentioned solution of the present invention breaks through the limitation of single rotation gear feedback, realizes full-range gear recognition of sliding rotation compound operation, and further improves the operation accuracy; the elongated recessed part 213 can reduce the cooperation resistance during sliding and ensure smooth sliding action.

[0051] Preferably, the protruding surface of the convex ridge 212 is a smooth surface with an arc transition design. This means that the top surface and both sides of the convex ridge 212 are rounded, so that when the protruding part 122 contacts the convex ridge 212, it is a surface contact rather than an edge contact. This not only provides guidance for the protruding part 122, making the gear shifting feel smoother and avoiding the jamming or difficult operation caused by the pressure of the edge, thus improving the user's operating experience, but also reduces frictional resistance, reduces frictional wear between the convex ridge 212 and the protruding part 122 during rotation, and extends the service life of both.

[0052] Furthermore, a through groove 117 is provided on the side wall of the receiving groove, the through groove 117 connects the receiving groove with the first outer groove 112 on the outside, and provides an installation channel for the protrusion 122.

[0053] like Figure 10 As shown, the fixing part 10 also includes a paddle 12, which is made of elastic material and includes two symmetrically arranged elastic arms 121. The ends of the two elastic arms 121 are bent inward and connected to form a "V"-shaped protrusion 122. The roots of the two elastic arms 121 are movably connected to the first outer groove 112. The protrusion 122 passes through the through groove 117 and extends into the receiving groove, where it is inserted into the recessed part 213.

[0054] Preferably, a limiting part 115 is provided at the bottom of the first outer groove 112, and the roots of the two elastic arms 121 abut against the limiting part 115 for limiting.

[0055] Specifically, when the lever 12 is assembled, the roots of the two elastic arms 121 respectively fit against the bottom wall of the first outer groove 112 and are limited by the corresponding limiting part 115. The protrusion 122 passes through the through groove 117 and abuts against the outer wall of the induction magnet mounting part 211. The elastic arm 121 naturally opens to provide radial elastic force, so that the protrusion 122 fits tightly against the induction magnet mounting part 211. When the induction magnet mounting part 211 is rotated, the ridge 212 squeezes the protrusion 122, causing the elastic arm 121 to open and deform outward. After passing the ridge 212, the elastic arm 121 returns to its original position, and the protrusion 122 is embedded in the recess 213.

[0056] In the above solution, the paddle 12 is integrally molded, with a simple structure and low cost. The elasticity of the elastic arm 121 can ensure a stable fit between the protrusion 122 and the recess 213, while also having good telescopic adaptability. The elastic telescopic of the protrusion 122 is achieved by using a single paddle 12, eliminating the need for additional elastic components and simplifying the assembly process.

[0057] Optionally, a retaining groove 115 is formed at the bottom of the first outer groove 112 corresponding to the root of the elastic arm 121. During assembly, the retaining groove engages with the retaining part 115 to restrict the circumferential and axial displacement of the paddle 12 within the first outer groove 112, ensuring that the protrusion 122 is always aligned with the through groove 117. This avoids the paddle 12 shifting during long-term use, causing the protrusion 122 to deviate from the through groove 117, thus ensuring the stability of the gear feedback structure. The retaining and fixing method is simple, facilitating quick assembly and subsequent replacement of the paddle 12.

[0058] Preferably, two levers 12 are symmetrically arranged in the receiving groove, and the two levers 12 are arranged symmetrically along the central axis of the receiving groove.

[0059] Specifically, the through slots 117 and limiting parts 115 corresponding to the two paddles 12 are symmetrically arranged. After assembly, the two protrusions 122 simultaneously abut against the outer wall of the induction magnet mounting part 211 and are synchronously inserted into the recessed part 213. The symmetrically arranged paddles 12 can provide balanced radial elastic force, avoiding uneven wear or rotational jamming caused by uneven force on the induction magnet mounting part 211; at the same time, it enhances the tactile feedback of the gear position, making the feedback clearer and more stable, and improving the reliability of operation.

[0060] Optionally, the lever 12 is formed by bending stainless steel wire.

[0061] In some implementations, such as Figure 7 As shown, the inner base 11 also has a second outer groove 114 surrounding the outer side of the inner groove 111, the second outer groove 114 being disposed opposite to the first outer groove 112; a support member 13 is fixedly provided in the second outer groove 114, the support member 13 having a support portion 131, the support portion 131 being inserted into the through groove 117 and abutting against the protrusion 122.

[0062] Specifically, the first outer groove 112 and the second outer groove 114 are located on the upper and lower sides of the inner base 11, respectively, forming a symmetrical groove layout. A support member 13 is fixed in the second outer groove 114 by fasteners (screws, clips, etc.) or adhesive. The support member 13 has a support portion 131 extending in the axial direction of the receiving groove. The support portion 131 is inserted axially into the through groove 117 and abuts against the protrusion 122, providing a reverse support force for the protrusion 122.

[0063] In other words, such as Figure 5 As shown, after the support member 13 is assembled and fixed, the support part 131 extends into the through groove 117, and its end face abuts against one side of the protrusion 122 of the lever 12. When the knob part 20 slides and rotates at the same time, the protrusion 122 is squeezed and deformed downward by the protrusion 212. The support part 131 can limit its excessive deformation and avoid fatigue damage to the elastic arm 121.

[0064] The above solution limits the elastic deformation of the paddle 12 to prevent the elastic arm 121 from being overstretched or bent and failing due to long-term frequent operation, thus extending the service life of the paddle 12; at the same time, it improves the stress stability of the protrusion 122 and avoids excessive deformation from affecting the gear feedback accuracy.

[0065] Preferably, such as Figure 4 As shown, the inner base 11 is connected to an anti-slip pad 14, which is made of flexible anti-slip materials such as silicone and rubber, and covers the bottom contact surface of the inner base 11.

[0066] Specifically, the anti-slip pad 14 is bonded and fixed to the bottom of the inner base 11 with adhesive backing to ensure a tight fit without air bubbles. After assembly, the anti-slip pad 14 contacts the mounting surface of the home appliance, fills the gaps and provides friction, which can enhance the friction between the inner base 11 and the mounting surface, prevent the components from shifting during operation, and improve installation stability. The flexible material can buffer the vibration of operation, reduce noise, and at the same time prevent dirt and water stains from the mounting surface from penetrating the inner base 11, thus playing a protective role.

[0067] In some embodiments, an annular flange 116 is provided on the outer side wall of the inner base 11, and an elastic reset member 25 is sandwiched between the annular flange 116 and the knob base 21. The elastic reset member 25 is configured to have an elastic force that automatically resets the knob base 21 after it slides down, thereby realizing the automatic rebound function of the sliding action.

[0068] Specifically, the elastic reset member 25 is sleeved on the outside of the inner base 11, with its upper end abutting the lower surface of the knob base 21 and its lower end abutting the upper surface of the annular flange 116. In its natural state, the elastic reset member 25 is in a slightly compressed state, providing upward support for the knob base 21. When the knob base 21 is pressed down and slids downward, the elastic reset member 25 is further compressed and stores elastic potential energy. After being released, the elastic potential energy is released, pushing the knob base 21 upward to reset to its initial position. This achieves automatic reset of the pressing action, eliminating the need for manual lifting by the user and improving operational convenience. The supporting effect of the elastic reset member 25 keeps the knob base 21 in a stable initial position, avoiding magnetic field deviation caused by gravity and ensuring detection accuracy.

[0069] Preferably, the fixing part 10 further includes an outer base 15, the outer base 15 abutting against the annular flange 116 to form a limiting groove, and one end of the elastic reset member 25 is embedded in the limiting groove to realize the positioning and installation of the elastic reset member 25.

[0070] Specifically, the outer base 15 and the inner base 11 are fixed by a snap fastener, and their inner sidewalls are fitted with the outer sidewalls of the annular flange 116 to form a limiting groove. The lower end of the elastic reset member 25 is embedded in the limiting groove to restrict its circumferential displacement and ensure that the elastic reset member 25 always extends and contracts along the axial direction.

[0071] In other words, by circumferentially limiting the elastic reset member 25, the elastic reset member 25 is prevented from twisting and deforming during rotation, thus extending its service life; at the same time, the force on the elastic reset member 25 is made more uniform, ensuring that the reset action is smooth and stable without deviation or jamming.

[0072] Preferably, the elastic reset member 25 is a spring, specifically a compression spring, whose inner diameter is adapted to the outer side wall of the inner base 11 and whose outer diameter matches the size of the limiting groove.

[0073] When assembling, the compression spring is sleeved on the outside of the inner base 11, with both ends fitting against the knob base 21 and the bottom of the limiting groove, respectively, to ensure that the spring axis coincides with the axis of the induction magnet mounting part 211 without tilting or offset.

[0074] Compression springs have the advantages of stable elastic recovery performance, long service life, and low cost, making them suitable for frequent sliding operation scenarios. Their compact structure makes them easy to install in limited spaces, and the elastic force is adjustable, allowing for precise matching of the reset force according to the weight of the knob.

[0075] In some implementations, such as Figure 4 and Figure 5 As shown, the knob part 20 also includes a knob housing 22, which covers the outside of the knob base 21 and is connected to the knob base 21, for example by fastening with buckles or screws, to ensure that the two rotate and slide synchronously, while also serving a decorative and protective function.

[0076] Specifically, after the knob housing 22 is fitted onto the knob base 21, it is secured and positioned by circumferential snap-fit, or by a screw threaded through the top of the knob housing 22 and the knob base 21. After assembly, the knob housing 22 is secure, its surface is flush with the knob base 21, and there are no steps or protrusions. This shielding and protecting the knob base 21 and its internal structure prevents the intrusion of oil fumes and dust, improving the cleanliness and durability of the components; it also increases the user's contact area, making it easier to apply force and improving operating comfort.

[0077] Preferably, the knob housing 22 extends axially to the outer side of the outer base 15, and its inner sidewall is clearance-fitted with the outer sidewall of the outer base 15. It can be limited to rotate relative to the outer base 15, that is, the knob housing 22 does not rub against the outer base 15 when it rotates, and axial movement is avoided by structural limitation.

[0078] Optionally, refer to Figure 11 As shown, the inner diameter of the extended section of the knob housing 22 is slightly larger than the outer diameter of the outer base 15, forming a small fitting gap. Simultaneously, the inner side of the knob housing 22 is provided with two axially spaced limiting protrusions 223, and the outer side of the outer base 15 is provided with a limiting step 151. Together, these elements, along with a reset elastic element, restrict the axial displacement of the knob housing 22 to within the interval defined by the two limiting protrusions 223, thereby confirming the sliding-rebound distance of the knob portion 20. Furthermore, the limiting protrusions 223 and the limiting step 151 can be a continuous structure or an intermittent structure.

[0079] In the above solution, the axial length of the knob housing 22 is extended to further improve the protection range and prevent foreign objects from entering through the gap between the knob base 21 and the outer base 15; the limiting structure can prevent the knob housing 22 from sliding down excessively, protect the elastic reset member 25 and the internal structure, and at the same time ensure smooth rotation without interference.

[0080] Furthermore, the knob housing 22 includes an annular housing 221 and a knob cover 222 covering the upper opening of the annular housing 221. The two are fixed by snap-fit ​​or ultrasonic welding to form a complete housing structure.

[0081] The annular housing 221 is fixedly connected to the knob base 21, causing the knob base 21 to move synchronously; the knob cover 222 closes the opening of the annular housing 221, forming an aesthetically pleasing top appearance. The two limiting protrusions 223 mentioned above are provided on the inner sidewall of the annular housing 221.

[0082] Preferably, the knob cover 222 is made of a light-transmitting material, such as transparent PC or acrylic. A light-shielding sheet 23 is provided between the knob cover 222 and the knob base 21. The light-shielding sheet 23 can be printed with markings, scales, and other patterns to achieve a light-transmitting display function.

[0083] Specifically, the light-shielding plate 23 is fixed to the knob base 21 with adhesive backing and is located below the knob cover 222. Its printed pattern corresponds to the knob's gear position. When the component is equipped with an indicator light, light can pass through the non-printed area of ​​the light-transmitting cover and the light-shielding plate 23 to display the current gear position or working status. This enables a visual display of the gear position or working status, and combined with the tactile feedback of the gear position, it further improves the accuracy of operation. The combined design of the light-transmitting cover and the light-shielding plate 23 enriches the appearance while avoiding exposure of the internal structure, thus improving aesthetics.

[0084] The assembly method of the fixing part 10 and the knob part 20 of the magnetic control knob assembly 100 provided by the present invention is as follows: First, the knob cover 222 and the light shield 23 are sequentially installed into the annular housing 221 to form the knob housing 22; then, the sensing magnet 24 is installed into the sensing magnet mounting part 211 of the knob base 21, and then the knob base 21 together with the sensing magnet 24 is installed into the knob housing 22 and fixed by the buckle to complete the assembly of the knob part 20.

[0085] Insert the support member 13 into the second outer groove 114 of the inner base 11 from the bottom side, so that the support part 131 is inserted into the through groove 117. Then, insert the paddle 12, the fixing magnet 17, and the fixing cover 16 into the first outer groove 112 of the inner base 11 from the top side to complete the assembly of the fixing part 10.

[0086] Finally, the elastic reset member 25, the fixing part 10, and the outer base 15 are sequentially installed into the knob housing 22 and secured by the outer base 15 and the knob housing 22. Finally, the anti-slip silicone pad is attached to the bottom of the inner base 11 to complete the overall installation.

[0087] In another embodiment, such as Figures 12 to 17 As shown, the elastic reset member 25 is removed, and the press reset function of the knob part 20 is achieved by the mutual repulsion of the two magnets.

[0088] Specifically, in this implementation, such as Figure 12 and Figure 13 As shown, the fixed magnet 17 is configured as a ring structure. Correspondingly, the first outer groove 112 does not have multiple mounting slots 113; the ring-shaped fixed magnet 17 is directly installed in the ring-shaped first outer groove 112. Furthermore, the knob base 21 is provided with a third outer groove 215 surrounding the outside of the sensing magnet mounting portion 211. A reset magnet 26 is disposed in the third outer groove 215. The reset magnet 26 is positioned opposite the fixed magnet 17, and their opposing magnetic poles are the same. Thus, when the knob portion 20 and the fixing portion 10 are assembled, the mutual repulsion between the reset magnet 26 and the fixed magnet 17 provides a reset pushing force for the knob portion 20.

[0089] Furthermore, in this embodiment, as Figures 14 to 17As shown, the outer wall of the induction magnet mounting part 211 does not have protruding ridges, and a first limiting structure 2111 is provided on the outer side of the induction magnet mounting part 211; at the same time, a rotating part 18 is provided in the inner groove 111, and the rotating part 18 has a through second receiving groove 181. A second limiting structure 182 is provided on the inner wall of the second receiving groove 181. The induction magnet mounting part is installed in the second receiving groove 181, and after being circumferentially limited by the first limiting structure 2111 and the second limiting structure 182, the knob base 21 can drive the rotating part 18 to rotate synchronously in the inner groove 111. It should be noted here that the first limiting structure 2111 and the second limiting structure 182 only provide circumferential limiting and do not provide axial limiting. The knob base 21 can slide up and down axially relative to the rotating part 18.

[0090] In this embodiment, a plurality of protruding ridges 212 are provided on the inner sidewall of the inner groove 111, and a recess is formed between two adjacent protruding ridges 212; the rotating part 18 is provided with an elastic positioning component 19, and as the rotating part 18 rotates, the elastic positioning component 19 sequentially forms an insertion engagement with the plurality of recesses.

[0091] Specifically, the rotating part 18 has a blind hole 183 extending radially; the elastic positioning component 19 includes an elastic element 191 and a steel ball 192. The elastic element 191 is disposed in the blind hole 183, and the end of the elastic element 191 abuts against the steel ball 192. As the rotating part 18 rotates, the arc-shaped surface of the steel ball 92 sequentially forms an interlocking fit with a plurality of the recesses, so that the knob has a clear gear feel when it is turned, and the user can intuitively perceive the switching of the fire level, avoiding over-adjustment or under-adjustment, and improving the operating experience.

[0092] like Figure 18 As shown, the present invention also provides a gas stove, including a control panel 200, a magnetic control knob assembly 100, and a display box 330 disposed at the lower end of the control panel 200. The fixing part 10 and the knob part 20 are attracted and fixed to the positioning magnet 321 at the bottom of the control panel 200 by a fixing magnet 17, as shown in the figure. Figure 18 As shown. After assembly, the knob housing 22 is exposed on the surface of the control panel 360. Users can perform operations such as gear adjustment and function switching by rotating and sliding the knob. The control panel 200 is made of a light-transmitting material. The display box 330 is equipped with a light-emitting element 310. The fixing part 10 and the knob part 20 are correspondingly arranged with the light-emitting element 310, so that the light emitted by the light-emitting element 310 passes through the control panel 200 and is displayed on the knob housing 22 of the knob part 20.

[0093] Compared to the method of illuminating the control panel 200 with the light-emitting element 310, the above solution allows the light emitted by the light-emitting element 310 to be displayed on the inner base 11 and the knob cover 222, ensuring that the user can observe the light effect displayed on the fixing part 10 and the knob part 20 at the first time, thereby ensuring that the user can judge the flame size of the gas stove 1 at the first time.

[0094] like Figure 19 and Figure 20 As shown, the display box 300 includes an upper housing 331, and the upper housing 331 is provided with a positioning seat 332 for mounting a positioning magnet 321; wherein, there is a gap between the positioning seat 332 and the upper housing 331, and the light-emitting element 310 is located below the gap, so that the light emitted by the light-emitting element 310 shines upward from the gap position.

[0095] Preferably, the positioning seat 332 has a circular structure, and an annular gap is formed between the positioning seat 332 and the upper housing 331.

[0096] To ensure that the light emitted by the light-emitting element 310 can be smoothly emitted to the fixing part 10 and the knob part 20, the control panel 200 of the gas stove 1 is made of a light-transmitting material, and a positioning seat 332 for installing the positioning magnet 321 is provided on the upper housing 331 of the display box 300. An annular gap is provided between the positioning seat 332 and the upper housing 331, so that the light emitted by the light-emitting element 310 shines upward from the position of the annular gap, so that the light emitted by the light-emitting element 310 penetrates the control panel 200 and is displayed on the fixing part 10 and the knob part 20.

[0097] By placing the light-emitting element in the display box, the power supply for the light-emitting element can be integrated into the display box, thus avoiding the problem of separately powering the light-emitting element and simplifying the structural complexity of the stove.

[0098] Optionally, the positioning seat 332 and the upper housing 331 are integrally formed structures; The positioning seat 332 and the upper housing 331 are connected by a plurality of spaced thin ribs 334; Preferably, the light-emitting element 310 consists of a plurality of LED beads spaced apart along a ring direction, with the LED beads and the thin ribs 334 arranged alternately.

[0099] To ensure that both the positioning seat 332 and the annular gap are simultaneously provided on the upper housing 331 of the display box 300, the positioning seat 332 and the upper housing 331 are connected by a thin rib 334. This ensures that the positioning seat 332 and the upper housing 331 are integrally formed, while also creating an annular gap between them. Furthermore, the multiple LED beads of the light-emitting element 310 are staggered with the thin rib 334 to prevent the thin rib 334 from interfering with the LED beads.

[0100] Furthermore, the thin rib 334 is provided on the side of the positioning seat 332 and the upper housing 331 facing the light-emitting element 310, and a distance is left between it and the upper end face of the upper housing 331 and the positioning seat 332, so as to ensure that the light is evenly projected onto the range of the fixing part 10 and the knob part 20 without shadows, thereby reducing the light loss and deviation of the light-emitting element 310.

[0101] Optionally, multiple positioning magnets 321 are provided, and the multiple positioning magnets 321 are arranged sequentially on the positioning base 332 along the circumferential direction; during positioning, the multiple fixed magnets 17 and the multiple positioning magnets 321 are attracted and connected in a one-to-one correspondence.

[0102] Optionally, sensor 340 is located in positioning base 332 and is used to detect the rotation angle and distance of induction magnet 24; display box 300 is provided with circuit board 311, on which control unit and light-emitting element 310 can be provided. Control unit controls the light-emitting element 310 to change the light according to the movement of induction magnet 24 detected by sensor 340; wherein, circuit board 311 can also realize the integrated setting of control unit, light-emitting element 310 and other electrical equipment to ensure that control unit can synchronously control multiple devices.

[0103] To further enhance the user's awareness of the light-emitting element 310, the light emitted by the light-emitting element 310 is not only displayed on the fixed part 10 and the knob part 20, but the movement of the fixed part 10 and the knob part 20 can also be detected by a sensor 340 located on one side of the display box 300. Specifically, the sensor 340 monitors the rotation angle of the knob part 20 relative to the positioning part 100 and the displacement distance of the knob part 20 relative to the positioning part 100. The control unit controls the lighting effect of the light-emitting element 310 based on the movement status of the knob part 20 detected by the sensor 340, so that the user can judge the flame status of the gas stove 1 at the first time.

[0104] More specifically, during startup, the user first presses down and rotates the knob 20. When the sensor 340 detects the pressing action of the knob 20, the control unit controls the light-emitting element 310 to emit light and controls the light of the light-emitting element 310 to flash in the form of a breathing light. As the knob 20 is rotated, the control unit controls the light-emitting element 310 to change color. For example, the control unit can preset multiple combustion stages, and the color of each combustion stage is different. When ignition is successful, according to the rotation angle of the knob 20 detected by the sensor 340, the control unit controls the light-emitting element 310 to emit light of the corresponding color according to the preset combustion stage, so that the user can judge the flame status of the gas stove 1 in time.

[0105] Furthermore, the control unit may also include a control program for the placement state of the fixing part 10 and the knob part 20. When the user installs the fixing part 10 and the knob part 20 in the designated position of the gas stove 1, the sensor 340 detects the sensing magnet 24 of the fixing part 10 and the knob part 20. At this time, the control unit controls the light-emitting element 310 to emit light. If no other action of the knob part 20 is detected within one minute, the control unit controls the light-emitting element 310 to turn off.

[0106] Furthermore, sensor 340 can be a Hall sensor.

[0107] Preferably, the positioning base 332 is provided with a first fixing plate 350 for fixing the positioning magnet 321, and the first fixing plate 350 and the positioning base 332 are connected by a snap-fit ​​connection. More preferably, the sensor 340 is disposed on the first fixed plate 350.

[0108] Specifically, in order to ensure that the positioning magnet 321 is stably installed in the positioning seat 332, a first fixing plate 350 is provided on the positioning seat 332 for fixing the positioning magnet 321, so that the positioning magnet 321 is stably installed in the positioning seat 332; furthermore, the sensor 340 is located below the first fixing plate 350, while ensuring the installation stability of the sensor 340.

[0109] In the embodiments of this application, the inner base 11 and the knob cover 222 respectively form a light-transmitting path, and the light emitted by the light-emitting element 310 illuminates the control panel 200, the inner base 11 and the knob cover 222 in sequence; in addition, the sensing magnet 24 is disposed in the sensing magnet mounting part 211 of the inner base 11, so that the movement between the sensing magnet 24 and the knob part 20 is consistent, ensuring that the sensor 340 can accurately determine the displacement and rotation angle of the knob part 20, and ensuring that the control unit can accurately control the light-emitting element 310 to emit light of the corresponding color.

[0110] In the embodiments of this application, a light-shielding plate 23 may be provided between the inner base 11 and the knob cover 222, so that the light emitted by the light-emitting element 310 can form a ring light in the light-transmitting path formed by the combination of the inner base 11 and the knob cover 222; the inner base 11 may also be provided with a positioning groove for installing the light-shielding plate 23, so that the inner base 11 and the knob cover 222 are kept in a tight fit. If a gap is formed between the inner base 11 and the knob cover 222, the brightness of the light emitted by the light-emitting element 310 will be reduced, affecting the user's experience.

[0111] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
