Description

Technical fields:

[0001] This utility model relates to the field of panel technology, and in particular to a rice cooker panel. Background technology:

[0002] Existing rice cooker panels generally use physical buttons or have built-in push-button switches with insulating sheets on them. However, there is a gap between the physical buttons and the panel body, which makes them susceptible to moisture and water ingress, leading to short circuits in the internal circuitry and poor waterproofing performance. The insulating sheets on the surface of the built-in push-button switches are generally made of plastic film, which is prone to wear and tear after a period of use, resulting in surface damage. This not only affects the feel and appearance of the rice cooker, but also makes it easy for moisture to seep into the interior. There is an urgent need for a rice cooker panel with better waterproofing performance. Summary of the Invention:

[0003] The purpose of this invention is to provide a rice cooker panel that has good waterproof performance and a long service life, addressing the shortcomings of existing technologies.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a rice cooker panel, comprising a panel layer, a button post, a double-lip sealing ring, a waterproof isolation chamber, a magnetic spring-loaded base, and a micro switch. The panel layer has a through hole through which the button post slidably passes. A first magnetic ring is fixedly fitted at the bottom of the button post. The double-lip sealing ring is disposed between the button post and the inner wall of the through hole. The waterproof isolation chamber is disposed at the bottom of the panel layer. A flexible panel is disposed on the top of the waterproof isolation chamber, and the two ends of the flexible panel are... The magnetic spring base is fixedly connected to the top two sides of the waterproof isolation chamber. The magnetic spring base is set inside the waterproof isolation chamber. A second magnetic ring is set on the magnetic spring base, and the magnetic polarity of the upper surface of the second magnetic ring is opposite to that of the lower surface of the first magnetic ring. The micro switch is set on the magnetic spring base, and the pressing end of the micro switch is close to the bottom of the soft panel. When the button is pressed down, it repels the magnetic spring base, causing the soft panel to press down and abut against the pressing end of the micro switch. The micro switch switches from an electrically disconnected state to an electrically connected state.

[0005] A further improvement to the above scheme is that both the first magnetic ring and the second magnetic ring are made of neodymium iron boron magnets.

[0006] A further improvement to the above solution is that the double-lip sealing ring includes an upper lip and a lower lip, the upper lip being press-fitted to seal the inner wall of the through hole, and the lower lip abutting against the outer wall of the button post.

[0007] A further improvement to the above solution is that the double-lip sealing ring is integrally molded using liquid silicone.

[0008] A further improvement to the above solution is that a limiting tension clamp is also provided on the button post, and the limiting tension clamp is detachably provided on the button post by screws.

[0009] A further improvement to the above scheme is that the inner wall edge of the through hole is provided with an r-angle.

[0010] A further improvement to the above solution is that a hydrophobic groove is formed on the soft surface plate, and a water-absorbing resin is provided at the outlet of the hydrophobic groove.

[0011] A further improvement to the above scheme is that a stainless steel shielding layer is provided around the magnetic rebound base.

[0012] The beneficial effects of this utility model are as follows: This utility model includes a panel layer, a button post, a double-lip sealing ring, a waterproof isolation chamber, a magnetic rebound base, and a micro switch. A through hole is formed in the panel layer, through which the button post slidably passes. A first magnetic ring is fixedly fitted at the bottom of the button post. The double-lip sealing ring is disposed between the button post and the inner wall of the through hole. The waterproof isolation chamber is disposed at the bottom of the panel layer, and a flexible panel is disposed on the top of the waterproof isolation chamber, with both ends of the flexible panel fixedly connected to the micro switch. On both sides of the top of the waterproof isolation chamber, the magnetic rebound base is disposed inside the waterproof isolation chamber. A second magnetic ring is disposed on the magnetic rebound base, and the magnetic polarity of the upper surface of the second magnetic ring is opposite to that of the lower surface of the first magnetic ring. The micro switch is disposed on the magnetic rebound base, and the pressing end of the micro switch is close to the bottom of the soft panel. When the button column is pressed down to repel the magnetic rebound base and cause the soft panel to press down and abut against the pressing end of the micro switch, the micro switch switches from an electrically disconnected state to an electrically connected state.

[0013] This utility model features a double-lip sealing ring in the panel layer through-hole, working in conjunction with an internal waterproof isolation chamber to achieve a double sealing effect. The double-lip sealing ring prevents moisture from seeping into the interior, while the internal waterproof isolation chamber protects the internal circuit structure. The first magnetic ring at the bottom of the button post works in conjunction with the second magnetic ring on the magnetic rebound base to achieve magnetic repulsion and rebound. Combined with the friction between the double-lip sealing ring and the button post, this achieves a button damping effect, resulting in a better button feel. The magnetic rebound reduces mechanical damage to the button, extends its service life, and provides excellent waterproof performance, enabling it to adapt to the high-temperature operating environment of rice cookers.

[0017] Explanation of reference numerals in the attached diagram: Panel layer 1, Through hole 11, R-angle 12, Button post 2, First magnetic ring 21, Limiting and loosening clamp 22, Double lip sealing ring 3, Upper lip 31, Lower lip 32, Waterproof isolation chamber 4, Soft panel 41, Drainage groove 411, Water-absorbing resin 412, Magnetic rebound base 5, Second magnetic ring 51, Stainless steel shielding layer 52, Micro switch 6. Detailed implementation method:

[0018] The present invention will be further described below with reference to the accompanying drawings, such as... Figure 1-3 As shown, this utility model provides a rice cooker panel, including a panel layer 1, a button post 2, a double-lip sealing ring 3, a waterproof isolation chamber 4, a magnetic spring-loaded base 5, and a micro switch 6. A through hole 11 is provided on the panel layer 1, through which the button post 2 slidably passes. A first magnetic ring 21 is fixedly fitted at the bottom of the button post 2. The double-lip sealing ring 3 is disposed between the button post 2 and the inner wall of the through hole 11. The waterproof isolation chamber 4 is disposed at the bottom of the panel layer 1, and a soft panel 41 is disposed on the top of the waterproof isolation chamber 4. Both ends of the soft panel 41 are fixedly connected to the top sides of the waterproof isolation chamber 4. The magnetic spring-loaded base 5 is disposed inside the waterproof isolation chamber 4, and a second magnetic ring 51 is disposed on the magnetic spring-loaded base 5. The magnetic polarity of the upper surface of the second magnetic ring 51 is opposite to that of the lower surface of the first magnetic ring 21. The micro switch 6 is disposed on the magnetic spring-loaded base 5, and the pressing end of the micro switch 6 is close to the bottom of the soft panel 41. When the button post 2 is pressed down... When the soft panel 41 is pressed down by the magnetic repulsion and rebound base 5 and comes into contact with the pressing end of the micro switch 6, the micro switch 6 switches from an electrically disconnected state to an electrically connected state. The through hole 11 of the panel layer 1 is provided with a double-lip sealing ring 3, which, together with the internal waterproof isolation chamber 4, achieves a double sealing effect. The double-lip sealing ring 3 prevents moisture from seeping into the interior, and the internal waterproof isolation chamber 4 protects the internal circuit structure. The first magnetic ring 21 at the bottom of the button post 2, together with the second magnetic ring 51 on the magnetic repulsion and rebound base 5, achieves magnetic repulsion and rebound. Combined with the friction between the double-lip sealing ring 3 and the button post 2, a button damping effect is achieved, resulting in a better button feel. The magnetic rebound reduces mechanical damage to the button, has a longer service life, and has good waterproof performance, which can adapt to the high-temperature operating environment of rice cookers. Among them, the soft panel 41 of this utility model is made of waterproof silicone material, which can achieve elastic recovery while being waterproof. Of course, it can also be made of other soft waterproof materials, and this utility model is not limited to this.

[0019] Both the first magnetic ring 21 and the second magnetic ring 51 of this utility model are made of neodymium iron boron magnets. Neodymium iron boron magnets have strong high temperature resistance and will not demagnetize even in the high temperature environment of rice cookers, thus ensuring the tactile feedback of the buttons.

[0020] This utility model double-lip sealing ring 3 includes an upper lip 31 and a lower lip 32. The upper lip 31 is press-fitted to seal the inner wall of the through hole 11, and the lower lip 32 abuts against the outer wall of the button post 2. The upper lip 31 statically seals the gap between the inner wall of the through hole 11 and the button post 2, and the lower lip 32 rolls and deforms as the button post 2 slides to achieve dynamic sealing. The upper lip 31 and the lower lip 32 work together to provide a double seal, resulting in good waterproof performance.

[0021] The double-lip sealing ring 3 of this utility model is integrally molded from liquid silicone, which can adapt to the use environment with large temperature differences, prevent aging from causing a decrease in waterproof performance, and at the same time prevent aging and hardening from causing a stiff button feel.

[0022] The button post 2 of this utility model is also provided with a limiting tension clamp 22. The limiting tension clamp 22 is detachably set on the button post 2 by screws. The tension clamp can abut against the top lower wall of the panel layer 1 to realize the limiting of the button post 2, and prevent the button from popping out too much due to magnetic repulsion. When the magnetic ring is used for a long time, the repulsion will inevitably weaken. The gap between the button post 2 and the magnetic rebound base 5 can be adjusted by adjusting the limiting tension clamp 22 to ensure stable friction and prevent the button feel from being affected by uncontrolled repulsion.

[0023] The inner wall edge of the through hole 11 of this utility model is provided with an R angle 12, which can be polished by laser to transform the acute angle of the inner wall edge of the through hole 11 into a rounded corner of r0.05mm, so as to avoid the acute angle cutting the double lip sealing ring 3 and reducing the waterproof performance.

[0024] The flexible panel 41 of this utility model has a hydrophobic groove 411, and a water-absorbing resin 412 is provided at the outlet of the hydrophobic groove 411. Even if liquid accidentally seeps into the panel layer 1, the liquid will be guided into the water-absorbing resin 412 through the hydrophobic groove 411, ensuring the normal operation of the internal micro switch 6 circuit.

[0025] The magnetic rebound base 5 of this utility model is provided with a stainless steel shielding layer 52 on its periphery to prevent the magnetic force of the magnetic rebound base 5 from interfering with the micro switch 6.

[0026] Of course, the above are only preferred embodiments of this utility model. Therefore, all equivalent changes or modifications made in accordance with the structure, features and principles of this utility model patent application are included in the scope of this utility model patent application.
