Abstract
Description
Technical Field
[0001] This utility model relates to the field of electromagnetic heating appliances, and in particular to a waterproof 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 a significant drawback: 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. Therefore, the existing temperature measurement method has a major hidden danger in preventing liquid leakage and needs further improvement. Utility Model Content

[0028] Example
[0029] Reference Figures 1 to 3 The present invention proposes a waterproof temperature measuring structure for an all-glass IH heating health pot, comprising: an all-glass pot body 10, a base 20, a telescopic spring 30, an elastic rubber cover 40, and a temperature sensor 50.
[0030] 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 temperature measuring hole 23; the temperature sensor 50 is fixed to the elastic rubber cover 40; the outer edge of the elastic rubber cover 40 is snapped into the temperature measuring hole 23, and the telescopic spring 30 is installed on the lower side of the temperature sensor 50.
[0031] In this invention, the elastic cap 40 serves as the core sealing component. Its outer edge is tightly fitted into the temperature sensing hole 23 of the microcrystalline plate 22, forming a reliable water-tight barrier. This completely prevents overflowing liquid from entering the base 20 through this path, thereby greatly improving the product's safety and long-term reliability in humid environments. Simultaneously, this structure achieves waterproofing while maintaining accurate temperature sensing and response speed. The telescopic spring 30 continuously provides upward thrust to the temperature sensor 50, ensuring stable and sufficient contact between its top and the magnetic conductive film layer 11 at the bottom of the glass container. This reduces temperature measurement lag and errors, enabling the IH heating system to achieve more precise temperature control. The elastic cap 40 integrates the dual functions of fixing the sensor and providing a seal. The microcrystalline plate 22 itself, as a supporting platform, does not require significant modifications to the existing base 20 structure, making the overall solution easy to assemble and manufacture, with good manufacturability and economy.
[0032] In this embodiment, a ceramic sleeve 51 is provided at the top of the temperature sensor 50. The high temperature resistance and low thermal conductivity of ceramic materials can effectively block some of the high-temperature heat generated by the electromagnetic heating module 21 from being directly conducted to the sensor, preventing it from being damaged or having inaccurate measurements due to overheating, thereby improving the reliability, durability and temperature measurement accuracy of the sensor.
[0033] In this embodiment, the elastic cap 40 has a central through hole 41 in its center; the ceramic sleeve 51 is embedded in the central through hole 41; or the elastic cap 40 is injection molded onto the ceramic sleeve 51. Both "embedding" and "secondary injection molding" ensure a strong, stable, and sealed integrated structure between the ceramic sleeve 51 and the elastic cap 40. This integrated design avoids relative displacement or gaps between components, further enhancing the overall structural strength and waterproof sealing effect, while also facilitating production and assembly.
[0034] Furthermore, the inner wall of the central through hole 41 and the outer wall of the ceramic sleeve 51 are provided with matching annular ribs 42 and annular grooves 52. The interlocking of the annular ribs 42 and annular grooves 52 forms a reinforced locking structure similar to a "labyrinth seal." This significantly increases the bonding force and sealing contact area between the ceramic sleeve 51 and the elastic rubber cap 40, effectively preventing loosening or separation during long-term use or due to thermal expansion and contraction, ensuring the long-term structural integrity and sealing reliability of the core temperature sensing component.
[0035] In this embodiment, the elastic cap 40 has an upward-arching center, and the temperature sensor 50 is located in the center of the elastic cap 40. Designing the center of the elastic cap 40 to be arched upwards provides it with a certain degree of elasticity and deformation space. This structure allows the center of the cap to elastically deform when the kettle is placed down, providing a gentler cushioning to prevent damage to the sensor or the bottom of the kettle. Furthermore, its rebound force assists the spring, ensuring a tight and secure contact between the sensor and the bottom of the kettle.
[0036] Specifically, the bottom of the all-glass vessel 10 has an upward-facing recessed temperature sensing part 12; the tip of the temperature sensor 50 can extend into the recessed temperature sensing part 12. The upward-facing recessed temperature sensing part 12 on the bottom of the all-glass vessel creates a natural positioning and accommodating space. This design allows the tip of the temperature sensor 50 to extend into it, which not only enables more accurate measurement of the temperature in the central region of the liquid inside the vessel and reduces interference from edge effects, but also provides some mechanical protection for the sensor, preventing scratches to the sensor head when the vessel is moved horizontally.
[0037] 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 temperature measuring 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 temperature measuring 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 temperature measuring hole 23. The cap outer wall 43 is attached to the hole wall, thus achieving the main seal. The upper annular outer edge 44 is attached to the upper edge of the temperature measuring hole 23, forming the first sealing edge to prevent lateral overflow. The lower annular flange 45 is attached to the lower edge of the temperature measuring hole 23, forming the second reverse sealing barrier and securing the microcrystalline plate 22 from below. This "upper and lower clamping" structure greatly extends the possible liquid penetration path, resulting in an extremely significant and stable sealing effect.
[0038] Furthermore, the lower annular flange 45 is provided with a sealing groove 46 for applying sealant. The sealing groove 46 in the lower annular flange 45 provides a designated space for applying sealant. This allows for secondary reinforcement sealing during production by applying sealant, and the use of adhesive can be flexibly selected according to different waterproofing requirements, greatly improving the process adaptability and ultimate waterproofing capability of the structure.
[0039] 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 temperature measuring 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 passage 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 50, and the lower end abuts against the inner cavity of the mounting seat body 61. The abutment flange 62 abuts against the lower side of the lower annular flange 45: providing stable and reliable lower support and limiting for the entire elastic rubber cover 40 assembly. The wire passage hole: standardizes the routing of the wire harness and avoids the risk of interference or wear caused by messy wiring. The lower end of the telescopic spring 30 abuts against the inner cavity of the mounting seat body 61: providing a stable force application base for the spring and ensuring that the direction of the lifting force is always vertically upward.
[0040] Furthermore, the mounting body 61 is provided with a drain hole 63, the top of which connects to the inner cavity of the mounting body 61. Even if a very small amount of liquid accidentally breaks through the multiple seals above, or accumulates in the inner cavity of the mounting body due to condensation or other reasons, the drain hole 63 can promptly drain it to the non-electrical area below or the outside of the base 20, instead of allowing it to accumulate and soak the sensor and wiring harness. This fundamentally eliminates the risk of malfunction due to internal water accumulation and improves the stability of the system.
[0041] 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.
