[0024] The technical solutions in the embodiments of this utility model will now be clearly and completely described in conjunction with the accompanying drawings.

[0025] Reference Figures 1 to 7 A heating base includes a base body 1, which includes a protrusion 11 on its upper end and an upwardly projecting portion, and a temperature sensing component 2 disposed within the protrusion 11. The temperature sensing component 2 includes a connector 21 disposed on the protrusion 11 and movable back and forth, a temperature sensing probe 22 inserted into the connector 21 and extending out of the protrusion 11, a cover plate 23 detachably disposed within the protrusion 11 and located behind the connector 21, and a spring 24 disposed between the connector 21 and the cover plate 23. This placement of the temperature sensing component 2 on the protrusion 11 allows for more accurate temperature detection of the kettle body 7. Furthermore, the components of the temperature sensing component 2 are assembled using snap-fit ​​mechanisms before being connected to the inner shell 12, facilitating assembly, thereby improving production efficiency and saving labor time; it also aligns with the product's minimalist aesthetic concept, further enhancing its overall appearance.

[0026] In this design, the protrusion 11 and the base 1 are integrally formed. The base 1 includes an inner shell 12 and an outer shell 13 disposed outside the inner shell 12. The inner shell 12 has an opening 121 for the temperature sensor 22 to extend out. This integral design of the protrusion 11 and the base 1 saves on the number of molds and reduces production costs; furthermore, the integral structure improves the overall rigidity and sealing of the base 1.

[0027] In this design, the connector 21 has a socket 211 that mates with the temperature probe 22. The temperature probe 22 includes a cylinder 221 inserted into the socket 211 and a limiting flange 222 located on the outside of the cylinder 221 and abutting against the rear side of the connector 21. The temperature probe 22 is a cylindrical NTC sensor, which not only has a simple design but also accurately senses the temperature of the kettle through point contact, providing more real-time, efficient, and precise transmission. Furthermore, the engagement of the socket 211 and the limiting flange 222 allows for quick installation and secure fixation of the temperature probe 22, preventing loosening or detachment during use.

[0028] In this design, the diameter of the insertion hole 211 gradually decreases from front to back. Several elastic latches 212 are provided on the rear side of the connector 21 along the outer edge of the insertion hole 211, and the limiting protrusion 222 abuts against the rear side of the elastic latches 212. This conical insertion hole 211 facilitates the insertion and alignment of the temperature sensor 22, reducing assembly difficulty. Simultaneously, the elastic latches 212 provide flexible fixation, allowing the temperature sensor 22 to move slightly to adapt to temperature changes, reducing stress concentration and preventing component breakage.

[0029] In this design, the connector 21 is provided with several guide holes 213, and the inner housing 12 is provided with a guide shaft 122 that mates with the guide holes 213. This ensures the precise movement trajectory of the connector 21 through the cooperation of the guide holes 213 and the guide shaft 122, preventing skewing or jamming, and ensuring that the temperature probe 22 always maintains perpendicular contact with the kettle body 7, thereby improving detection accuracy.

[0030] In this design, the front side of the cover plate 23 is provided with several plugs 231, the inner housing 12 is provided with a connecting shaft 123 that engages with the plugs 231, and the protrusion 11 is provided with a limiting structure that limits the installation position of the cover plate 23. This design of the plugs 231 and connecting shaft 123 makes the installation of the cover plate 23 simple and quick, allowing for disassembly without tools; simultaneously, the limiting structure ensures accurate positioning of the cover plate 23, avoids installation errors, and improves assembly efficiency and structural consistency. Specifically, the limiting structure includes several ribs 124 located on the outside of the connecting shaft 123 to limit the insertion distance of the plugs 231, and a limiting protrusion 131 located on the outer housing 13 that abuts against the rear side of the cover plate 23. The limiting protrusion 131 can be several ribs located on the side wall of the outer housing 13.

[0031] In this design, the base 1 further includes a heating plate 3 mounted on the inner housing 12 and a heat insulation cover 4 positioned between the inner housing 12 and the heating plate 3. This effectively solves the problem of product melting due to excessively high temperatures of the machine's heating plate column, thereby improving product safety and durability and protecting consumer safety.

[0032] In this design, the outer casing 13 is equipped with a control panel. The control panel includes a PC surface patch 5 covering the side wall of the outer casing 13, and a decorative frame 6 that presses and fixes the PC surface patch 5 to the outer casing 13. The decorative frame 6 is fixed to the outer casing 13 by a snap-fit ​​mechanism. This snap-fit ​​fixing method reduces the use of screws, simplifies the production process, and improves production efficiency. At the same time, the overall design conforms to the minimalist aesthetic of the product, making the product appearance more simple and elegant.

[0033] Reference Figure 8This utility model also provides a liquid heater, employing the heating base described above, with a kettle body 7 placed on the base 1. The bottom of the kettle body 7 contacts the temperature sensor 22, allowing the heating plate 3 to heat the kettle body 7. Temperature setting and display are achieved through a control panel. This liquid heater inherits all the advantages of the heating base, offering precise temperature control, efficient heating, and reliable safety. It is suitable for various liquid heating scenarios, such as boiling water and brewing tea, meeting diverse user needs.

[0034] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
