Existing kettle heating devices typically have an electric heating component installed at the bottom of a heating plate, which is in direct contact with the heated liquid. Because the entire heating plate is in contact with the heated liquid, the temperature of the area in the heating plate where the electric heating component is installed is higher than that of other areas. This causes more intense vaporization in the area where the electric heating component is installed during boiling, and the resulting bubbles are larger, making boiling very intense and even causing overflow, creating a dangerous situation.

[0023] The following describes the embodiments of the present invention in detail with reference to the accompanying drawings.
[0024] like Figures 1 to 4 As shown, a heating device of this embodiment, the heating device 1 includes: a heating plate 11 in direct contact with the heated liquid and an electric heating component 12 connected to the bottom of the heating plate 11, the surface of the heating plate 11 in contact with the heated liquid is provided with an isolation layer 111 for separating the heating plate 11 into a direct heating area 1101 and a heat insulation area 1102, the isolation layer 111 is made of high temperature resistant material, and the heating plate 11 is provided with an accommodating groove 1103 for accommodating the isolation layer 111, the heat insulation area 1102 is composed of the area where the isolation layer 111 is located, and the direct heating area 1101 is composed of the area of the heating plate 11 not covered by the isolation layer 111. The utility model provides an isolation layer for separating the heating disk into a direct heating zone and an insulation zone on the heating disk of the heating device, so that the surface of the heating disk can be separated into a direct heating zone and an insulation zone. Because the temperature of the surface of the insulation zone is lower than the temperature of the surface of the direct heating zone, bubbles will only be generated in the direct heating zone. Moreover, the direct heating zone is very finely separated by the isolation layer, and the temperature of the surface of the direct heating zone is more uniform, which can reduce the generation of bubbles, reduce the intensity of boiling, and improve safety.
[0025] In this embodiment, the direct heating zone 1101 comprises a plurality of mutually separated circular bosses 112 disposed on the heating plate 11. The diameter of each of the circular bosses 112 ranges from 1 mm to 2 mm, and the isolation layer 111 is disposed between adjacent circular bosses 112. When boiling water, each of the circular bosses 112 generates bubbles, allowing the direct heating zone to uniformly generate multiple small bubbles and prevent violent boiling.
[0026] In addition, the direct heating zone may also be of other shapes. For example, the direct heating zone 1101 includes a plurality of concentric rings (not shown) arranged on the heating plate 11, and the isolation layer 111 is arranged in the intervals between adjacent concentric rings.
[0027] In this embodiment, in order to ensure the use effect, the thickness of the isolation layer 111 is 0.15 mm to 0.2 mm.
[0028] In this embodiment, the upper surface of the isolation layer 111 is flush with the direct heating area 1101 , and the isolation layer 111 is completely located in the accommodating groove 1103 , which can prevent the isolation layer from falling off and improve the service life.
[0029] In this embodiment, the direct heating area 1101 and the heating plate 11 are integrally formed.
[0030] In this embodiment, the heating plate 11 is made of stainless steel or titanium, and the isolation layer 111 is made of Teflon.
[0031] like Figure 5-7 As shown, a kettle of this embodiment comprises: a kettle bottom 2, a kettle body 3, and the above-mentioned heating device 1. The lower end of the kettle body 3 is provided with an opening 301, and the heating device 1 is sealedly connected to the opening 301. A heating chamber 302 for holding water is provided between the kettle body 3 and the heating device 1. The kettle body 3 is connected to the kettle bottom 2 and is further provided with a spout 31 and a lid 32. The kettle of this utility model can reduce the intensity of boiling when boiling water, and has the advantage of high safety.
[0032] To achieve the tea-brewing function, in this embodiment, a tea strainer assembly 4 is provided within the kettle body 3. The tea strainer assembly 4 comprises a steam pipe 42, a steam collecting hood 43, and a tea basket 41 for placing tea leaves. The steam collecting hood 43 has a steam inlet 430 located directly above the heating plate 11. The steam pipe 42 connects the steam collecting hood 43 with the tea basket 41 to direct steam from the steam collecting hood 43 into the tea basket 41. The bottom of the tea basket 41 is provided with a tea-leafing hole 410. When the water in the kettle boils, small bubbles are transported along the steam collecting hood and steam pipe into the tea basket, achieving high-temperature tea brewing.
