Description

Technical Field

[0001] This utility model relates to the field of electromagnetic heating appliances, and in particular to a waterproof and anti-dry-burning temperature measuring structure for an all-glass iH heating health pot. Background Technology

[0002] Induction heating (IH) technology has been widely used in small kitchen appliances such as electric kettles and rice cookers due to its advantages of high efficiency, precision, and safety. In recent years, all-glass kettles have become a new market favorite due to their aesthetic appeal, chemical stability, and ease of cleaning. Applying IH technology to all-glass kettles typically requires coating the bottom of the glass with a magnetically conductive film layer (such as stainless steel or ferrite) to generate an eddy current effect for heating.

[0003] Currently, most all-glass IH heating health pots employ a protection technology that places a single temperature sensor in the center of the pot's bottom. This sensor is typically mounted in the middle of the base using a spring-loaded telescopic structure to achieve contact temperature measurement with the bottom of the pot. However, this structure has significant drawbacks: when liquid accidentally overflows to the upper part of the base, it can easily seep into the base through the gap between the temperature sensor and the mounting hole, causing internal electronic components to become damp, short-circuit, or corrode, thus affecting the product's reliability and safety; it also lacks timely feedback response for dry-boil detection when water is scarce. Therefore, further improvements are needed. Utility Model Content

[0014] Optionally, the base is provided with a temperature measuring mounting seat; the temperature measuring mounting seat is located below the central recess; the temperature measuring mounting seat includes a barrel-shaped mounting seat body and an abutment flange extending outward from the upper side of the outer edge of the mounting seat body; the mounting seat body is provided with a wire passing hole for the wire harness to pass through; the abutment flange abuts against the lower side of the lower annular flange; the upper end of the telescopic spring abuts against the temperature sensor, and the lower end abuts against the inner cavity of the mounting seat body.

[0015] The beneficial effects of this utility model are: 1. Excellent waterproof and leak-proof performance: By using an elastic cap structure that is snapped into the central hole of the microcrystalline plate, a complete seal is achieved for the opening of the temperature measuring area, effectively blocking the path of liquid seeping into the base from the contact surface between the pot and the base.

[0025] Example Reference Figures 1 to 3 The waterproof anti-dry-boil temperature measuring structure of the all-glass iH heating health pot proposed in this utility model includes: an all-glass pot body 10, a base 20, a telescopic spring 30, an elastic rubber cover 40, and an anti-dry-boil temperature measuring module 50. The bottom of the all-glass kettle body 10 is provided with a magnetic conductive film layer 11; the base 20 is provided with a working area; an electromagnetic heating module 21 is provided below the working area; a microcrystalline plate 22 is provided above the working area; the microcrystalline plate 22 has a central embedded hole 23; the anti-dry-burning temperature measuring module 50 is fixed to the elastic rubber cover 40; the outer edge of the elastic rubber cover 40 is snapped into the central embedded hole 23, and the telescopic spring 30 is installed on the lower side of the anti-dry-burning temperature measuring module 50; the anti-dry-burning temperature measuring module 50 includes a temperature sensor 51 and a liquid level sensor 52.

[0026] The beneficial effects of this utility model are: 1. Excellent waterproof and leak-proof performance: By using an elastic cap 40 structure to be snapped into the central hole 23 of the microcrystalline plate 22, a complete seal is achieved for the opening of the temperature measuring area, effectively blocking the path of liquid seeping from the contact surface between the pot body and the base 20 into the interior of the base 20, avoiding problems such as internal circuit short circuits and component corrosion caused by overflow, and greatly improving the electrical safety and long-term reliability of the product.

[0027] 2. Dual protection mechanism for more timely and accurate anti-dry-burning response: The anti-dry-burning temperature measurement module 50 integrates a temperature sensor 51 and a liquid level sensor 52, which can monitor the temperature and liquid level at the bottom of the kettle in real time, enabling rapid identification and feedback of water shortage and dry-burning. The system can cut off the heating power in time, fundamentally eliminating the risk of dry-burning and significantly improving the safety of use.

[0028] 3. Compact structure and stable and reliable installation: The telescopic spring 30 structure ensures good contact between the temperature measuring module and the magnetic conductive film layer 11 at the bottom of the pot, improving the accuracy of temperature detection; the elastic rubber cover 40 not only serves as a seal but also has a certain buffering performance, so that the overall structure can maintain stable and reliable temperature measurement and protection functions even in frequent use.

[0029] In this embodiment, the elastic cap 40 has an upward-curving center, and the anti-dry-burning temperature measuring module 50 is disposed in the center of the elastic cap 40. The structure of the elastic cap 40 with the center arched has good elastic deformation capability, which can not only ensure that the anti-dry-burning temperature measuring module 50 above maintains stable contact with the bottom of the pot, but also generate sufficient clamping force between the outer edge of the cap and the embedded hole of the microcrystalline plate 22, thereby enhancing the reliability of the sealing effect.

[0030] In this embodiment, the bottom of the all-glass kettle body 10 is provided with an upward-facing recessed temperature measuring part 12; the top of the temperature sensor 51 can extend into the recessed temperature measuring part 12. This improves temperature measurement accuracy and response speed: the recessed temperature measuring part 12 at the bottom of the kettle provides a natural housing space for the temperature sensor 51, ensuring a tight and close fit between the sensor tip and the heat-conducting area of ​​the kettle bottom, reducing thermal resistance, and making temperature detection more accurate and faster. Because the middle of the glass kettle is convex, when the water level is less than the convex surface, the liquid level sensor 52 activates, determining that the recessed temperature measuring part 12 is short of water, and heating can be stopped. At this time, there is still residual liquid around the convex area of ​​the glass kettle, and the buffer time for continued heating allows the liquid level sensor 52 to activate first, effectively reducing the risk of dry burning.

[0031] In this embodiment, a ceramic sleeve 53 is provided at the top of the temperature sensor 51; a central through hole 41 is provided in the middle of the elastic cap 40; the ceramic sleeve 53 is embedded in the central through hole 41; or the elastic cap 40 is injection molded onto the ceramic sleeve 53. Enhanced durability and insulation: The ceramic sleeve 53 has excellent wear resistance, high temperature resistance and electrical insulation, which can protect the temperature sensor 51 from mechanical wear and high temperature impact, and ensure electrical safety; whether embedded or injection molded, a seamless connection between the ceramic sleeve 53 and the elastic cap 40 is achieved, completely blocking the path that liquid may leak along the sensor surface, forming a double seal, and the connection structure is very stable.

[0032] Furthermore, the central through hole 41 and the outer wall of the ceramic sleeve 53 are provided with several matching limiting ribs 42 and limiting grooves 54. Through the cooperation of the limiting ribs 42 and limiting grooves 54, the ceramic sleeve 53 is prevented from rotating or loosening inside the rubber cover, ensuring the uniqueness and accuracy of the assembly position, and ensuring that the sensor is always in the optimal working position. At the same time, this interlocking structure also enhances the strength and reliability of the overall connection.

[0033] In this embodiment, a through hole is provided at the top of the ceramic sleeve 53, and the liquid level sensor 52 is attached below the through hole. This achieves non-contact detection: by attaching the capacitive liquid level sensor 52 below the through hole of the ceramic sleeve 53, the sensor can detect the liquid level inside the vessel through the ceramic medium without direct contact with the liquid or the vessel body, thus achieving reliable non-contact detection and avoiding contamination and corrosion.

[0034] In this embodiment, the temperature sensor 51 is an NTC temperature sensor 51; the liquid level sensor 52 is a capacitive liquid level sensor 52. The NTC temperature sensor 51 features high sensitivity, low cost, and high reliability, making it very suitable for temperature monitoring in such small household appliances. The capacitive liquid level sensor 52 has no moving mechanical parts, long lifespan, low power consumption, and is very suitable for detection through non-metallic media (such as glass and ceramics), providing accurate and durable detection.

[0035] In this embodiment, the outer edge of the elastic cap 40 is provided with a cap outer wall 43; the cap outer wall 43 is attached to the wall of the central embedded hole 23; the upper side of the outer edge of the cap outer wall 43 extends outward to form an upper annular outer edge 44, which is attached to the upper edge of the central embedded hole 23; the lower side of the outer edge of the cap outer wall 43 extends outward to form a lower annular flange 45, which is attached to the lower edge of the central embedded hole 23. A multi-layered three-dimensional sealing system is constructed: the contact between the cap outer wall 43 and the hole wall forms the first seal; the upper annular outer edge 44 presses against the upper edge of the embedded hole to form the second top seal; and the lower annular flange 45 presses against the lower edge of the embedded hole to form the third bottom seal. This "sandwich" type sealing structure completely blocks all possible paths for liquid entry from the top, bottom, and sides, resulting in an extremely significant waterproof effect.

[0036] Furthermore, the lower annular flange 45 is provided with a sealing groove 46 for filling with sealant. The design of the sealing groove 46 allows for the filling of sealant during assembly, achieving a combination of mechanical compression sealing and chemical bonding sealing, which greatly enhances the long-term stability and reliability of the sealing interface.

[0037] In this embodiment, the base 20 is provided with a temperature measuring mounting seat 60; the temperature measuring mounting seat 60 is located below the central recess 23; the temperature measuring mounting seat 60 includes a barrel-shaped mounting seat body 61 and an abutment flange 62 extending outward from the upper side of the outer edge of the mounting seat body 61; the mounting seat body 61 has a wire-passing hole for the wire harness to pass through; the abutment flange 62 abuts against the lower side of the lower annular flange 45; the upper end of the telescopic spring 30 abuts against the temperature sensor 51, and the lower end abuts against the inner cavity of the mounting seat body 61. Providing a stable mounting base: The temperature measuring mounting seat 60 provides a stable and independent mounting space for the entire anti-dry-burning temperature measuring module 50 and the telescopic spring 30, ensuring the stability of the component's operation. The cooperation between the abutment flange 62 and the lower annular flange 45 ensures that the elastic force of the telescopic spring 30 can be effectively transmitted upward, pressing the entire elastic rubber cover 40 sealing system, while also constituting part of the sealing structure itself.

[0038] Furthermore, the mounting body 61 is provided with a drain hole 63, the top of which is connected to the inner cavity of the mounting body 61. Even in extreme cases where a very small amount of liquid breaks through the multiple seals above, the drain hole 63 can promptly guide and discharge this liquid to the outside of the mounting body 61.

[0039] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
