Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this utility model. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0026] like Figures 1 to 5 As shown, this utility model provides a liquid heater, which includes a body device 10 and a base device 20 that are assembled together. The body device 10 is placed on the base device 20 to form an assembly connection.

[0027] The kettle body assembly 10 includes a kettle body component 11 and a rubber base component 12. The kettle body component 11 can contain liquid. The bottom of the kettle body component 11 is provided with a heating layer 111, which is an electromagnetic induction coating. The base device 20 and the heating layer 111 are electromagnetically connected to achieve electromagnetic induction heating.

[0028] The kettle body 10 and the base 20 are independently designed. The base 20 uses electromagnetic induction to create a waterproof structure and prevent leaks. The heating layer 111 and the base 20 are heated by electromagnetic induction, eliminating the need for direct electrical contact and preventing water-related electrical conductivity issues.

[0029] The heating layer 111 is located at the bottom of the kettle body assembly 11, and the rubber bottom assembly 12 is fastened to the bottom of the kettle body assembly 11 and covers the heating layer 111, forming a heating cavity between the rubber bottom assembly 12 and the kettle body assembly 11. The heating layer 111 can directly heat the bottom of the kettle body assembly 11, while the rubber bottom assembly 12 confines the heat from the other side of the heating layer 111 within the heating cavity, thereby preventing heat leakage and reducing heat loss. The rubber bottom assembly 12 can be made of rubber or plastic.

[0030] The rubber base assembly 12 is fastened to the body assembly 11 and covered with a heating layer 111 to form a heating cavity. The heat from the heating layer 111 is not easily radiated out of the heating cavity, thereby improving the heating efficiency of the body assembly 11 and reducing energy loss.

[0031] The rubber base assembly 12 has a groove structure and is snapped onto the body assembly 11. The rubber base assembly 12 is elastically fastened to the body assembly 11, ensuring a tight fit. The fit gap of the rubber base assembly 12 allows for pressure relief of the heating chamber while preventing expansion, thus improving the tightness of the connection.

[0032] Optionally, the adhesive base assembly 12 is provided with at least one venting micropore 121, which is connected to the heating chamber. During the fastening process of the adhesive base assembly 12, gas is discharged through the venting micropore 121.

[0033] In one embodiment, the pot body assembly 11 includes a pot body main body, which is made of glass or ceramic material. The pot body main body is an integral container structure, wherein the pot bottom part and the pot body part are integrally formed, resulting in good integrity.

[0034] Furthermore, the heating layer 111 is a metal layer that is attached to the bottom of the kettle body assembly 11. The metal layer is attached to the bottom of the kettle body assembly 11 with an adhesive to improve the tightness of the bond.

[0035] In another embodiment, the heating layer 111 is a metal layer sprayed onto the kettle body assembly 11. The heating layer 111 is formed by spraying the kettle body assembly 11 with a metal spraying process, resulting in high spray uniformity and high adhesion. The heating layer 111 is a spray-coated layer, which provides good heating effect.

[0036] In one embodiment, the rubber base assembly 12 includes a rubber base cover with a receiving groove, and the heating layer 111 is located within the receiving groove. The rubber base cover is a concave cover structure made of rubber material, the receiving groove is a concave space, and the inner side of the receiving groove is provided with a snap-fit ​​rib structure.

[0037] The bottom periphery of the pot body assembly 11 has a recessed snap-fit ​​groove 112. The snap-fit ​​groove 112 is located on one side of the bottom of the pot body. The bottom wall dimension of the pot body is smaller than the middle dimension of the pot body, so that the snap-fit ​​rib structure can be snapped into the snap-fit ​​groove 112.

[0038] The snap-fit ​​groove 112 is an arc-shaped concave snap-fit ​​groove 112 structure. The rubber base cover snaps into the snap-fit ​​groove 112. The outer peripheral wall size of the rubber base assembly 12 is less than or equal to the outer peripheral wall size of the body assembly 11. The outer peripheral walls of the rubber base assembly 12 and the body assembly 11 are flush. The outer peripheral wall of the rubber base assembly 12 is slightly smaller than the outer peripheral wall of the body assembly 11 to facilitate installation.

[0039] In one specific embodiment, the rubber base cover includes a base plate portion 123 and a ring-shaped fastener portion 122 surrounding the base plate portion 123. The ring-shaped fastener portion 122 is elastically fastened to the bottom of the kettle body assembly 11. The end of the ring-shaped fastener portion 122 has a fastening rib structure. The minimum dimension of the fastening rib structure is smaller than the dimension of the fastening groove 112, so that the fastening rib structure is elastically tensioned and fastened to the fastening groove 112 to achieve a locking connection.

[0040] In one embodiment, the rubber base cover is made of heat-insulating material and has a high-temperature resistant structure to facilitate the installation of elastic clips. The rubber base cover can block heat transfer, causing heat to concentrate at the bottom of the kettle body assembly 11.

[0041] In another embodiment, the rubber base assembly 12 includes a heat insulation element 113, which is integrally formed with the rubber base cover. The heat insulation element 113 is a heat insulation pad or heat insulation plate, and is located at the bottom of the receiving groove to achieve maximum heat insulation coverage. The rubber base cover can be elastically connected to the kettle body assembly 11, and the heat insulation element 113 achieves a heat-insulating fit, making assembly convenient.

[0042] In one embodiment, the base device 20 includes a base assembly 21 and an electromagnetic coil 22 mounted on the base assembly 21. The base assembly 21 is provided with a receiving groove, and the electromagnetic coil 22 is located in the receiving groove and corresponds to the heating layer 111. When the electromagnetic coil 22 is energized, an electromagnetic field can be generated. The heating layer 111 is within the range of the electromagnetic field, forming an induced current and generating heat, thereby heating the liquid.

[0043] The base assembly 21 is equipped with a coil holder 211, into which an electromagnetic coil 22 is embedded to achieve electromagnetic induction. The base assembly 21 adopts a shell structure to house the electromagnetic coil 22, thereby avoiding exposed conductive parts and reducing the risk of electric shock from water leakage.

[0044] In one embodiment, the base device 20 is provided with a temperature measuring component 23, which detects the liquid temperature inside the body assembly 11 beyond the area covered by the rubber base assembly 12. The temperature measuring component 23 can detect the liquid temperature in the body of the pot, and the detection area is far away from the heating layer 111 at the bottom of the body assembly 11, thereby improving the accuracy of temperature detection.

[0045] Preferably, the base device 20 is provided with a storage groove 212, the depth of which is greater than the height of the rubber base assembly 12. The body assembly 11 is snapped into the storage groove 212, which not only ensures stable assembly but also protects the body assembly 11.

[0046] Preferably, the temperature measuring component 23 is located on the wall of the storage slot 212 and faces the body of the kettle to detect the temperature of the kettle body. Optionally, the temperature measuring component 23 adopts non-contact temperature detection to avoid damaging the integrity of the kettle body.

[0047] Other embodiments of the present invention will readily occur to those skilled in the art upon consideration of the specification and practice of the disclosure herein. This application is intended to cover any variations, uses, or adaptations of the present invention that follow the general principles of the present invention and include common knowledge or customary techniques in the art not disclosed herein.
