[0033] As Figures 1 to 4 shown, the present utility model provides a kettle body structure. The kettle body structure 100 includes a kettle body assembly 10, a heating plate assembly 20, a heat conduction pad 30, and a bottom shell assembly 24. The heat conduction pad 30 is located between the kettle body assembly 10 and the heating plate assembly 20. The heating plate assembly 20 is located inside the bottom shell assembly 24, and the bottom shell assembly 24 covers the heating plate assembly 20. The heating plate assembly 20 can generate heat, and the kettle body assembly 10 is set as a container structure. The heating of the heating plate 22 can heat the liquid in the kettle body assembly 10.

[0034] The kettle body assembly 10 includes a heating kettle body 11 integrally formed into a container shape. Preferably, the heating kettle body 11 is made of glass material to form an integral container structure. Optionally, the kettle body assembly 10 is equipped with a handle 13 and a kettle lid 12 to achieve the functions of convenient carrying and opening / closing at the opening.

[0035] The heating plate assembly 20 is detachably installed at the bottom of the heating kettle body 11, and the heating plate assembly 20 is provided with a heating element. Optionally, the heating plate assembly 20 can be adopted. The two side surfaces of the heat conduction pad 30 are respectively attached to the heating kettle body 11 and the heating plate assembly 20. The heat conduction pad 30 is made of a material with high heat conductivity. Preferably, the heat conduction pad 30 is made of a heat conduction material with a stable form and an appropriate elastic deformation effect. For example, the heat conduction pad 30 adopts a flexible heat conduction pad, a heat conduction insulating elastic rubber, a heat conduction tape, and other heat conduction materials.

[0036] The heating element generates heat when powered on, and the heat conducting pad 30 is used to transfer the heat of the heating element to the kettle body assembly 10. Among them, the heat conducting pad 30 can concentrate the heat emitted by the heating plate assembly 20 on a specified area of the heating kettle body 11, thereby improving the heat concentration, enhancing the evenness of heat reception, and reducing heat loss. The heat conducting pad 30 has an appropriate elastic deformation effect, and the heating plate assembly 20 is connected to the heating kettle body 11, so that the heat conducting pad 30 can closely fit the heating kettle body 11. Optionally, the heating kettle body 11 is made of glass material, and the heat conducting pad 30 can also adapt to the shape fluctuations of the bottom of the heating kettle body 11 and always maintain a close fit state. Optionally, the heat conducting pad 30 can be laid on the bottom of the heating kettle body 11 to form a full-bottom heating. Optionally, the heat conducting pad 30 is annular to form an annular local high-temperature heating. Optionally, the heat conducting pad 30 can be set in the combined shape of an annulus and bumps, so that the temperature in the area covered by the heat conducting pad 30 rises, realizing controllable heating in the specified heating area.

[0037] Preferably, the thickness of the heat conducting pad 30 is set to t, where 0.3 mm ≤ t ≤ 6 mm. Specifically, the thickness of the heat conducting pad 30 can be set to 0.3 mm, 0.5 mm, 0.8 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 5 mm, 6 mm, etc. The thickness of the heat conducting pad 30 can be flexibly adjusted according to design requirements to achieve good heat conduction effect and installation tightness.

[0038] Preferably, the heating kettle body 11 is of an integral structure, with no gaps and clearances at the bottom, and no glue and rubber seals. The internal liquid is not affected, and the structure is simplified.

[0039] As Figures 2 to 6 shown, the heating plate assembly 20 is detachably assembled to the bottom of the heating kettle body 11 to form a connection structure. Optionally, the heating plate assembly 20 and the bottom of the heating kettle body 11 are connected by a clamp. Or, the heating plate assembly 20 is connected to the connection structure member fixed on the outer peripheral wall of the heating kettle body 11. For example, a connection frame is adhesively connected or embedded on the outer peripheral wall of the heating kettle body 11, and the heating plate assembly 20 is connected to the connection frame by screws.

[0040] In an embodiment, the heating kettle body 11 is provided with a snap groove 111 with an annular depression, and the heating plate assembly 20 is snap-connected to the snap groove 111 and presses the heat conducting pad 30 to fit the heating kettle body 11. The snap groove 111 is a depression structure formed by the depression of the outer peripheral wall of the heating kettle body 11, so that the outer peripheral wall of the heating kettle body 11 can cooperate with the snap structure of the heating plate assembly 20 for snap connection, thereby improving the connection convenience between the heating kettle body 11 and the heating plate assembly 20.

[0041] Optionally, the heating plate assembly 20 is provided with at least two adapted snap ribs 211, and the at least two snap ribs 211 are spaced apart to be snap-connected to the snap groove 111 from different angles. The heating kettle body 11 is inserted into the space between the at least two snap ribs 211 until the barbs on the snap ribs 211 are snapped into the snap groove 111, achieving elastic snap connection, which is convenient for connection and simplifies the connection structure.

[0042] In one embodiment, the heating plate assembly 20 includes a snap plate 21, a heating plate 22 mounted on the snap plate 21, and a heat insulation member 23. The heat conduction pad 30 covers one side surface of the heating plate 22, and the heat insulation member 23 is used to block the heat emitted from the other side surface of the heating plate 22. The heat insulation member 23 is made of a heat insulation material or a material with a low thermal conductivity to block the outward transfer of heat, thereby reducing the heat energy loss, concentrating the heat on the side of the heat conduction pad 30, and thus reducing the energy consumption.

[0043] The snap plate 21 is snap-connected to the heating kettle body 11, and the heating plate 22 is electrically connected to the power supply. The snap plate 21 defines the heating plate 22 and the heat insulation member 23 and is integrally connected to the heating kettle body 11. Optionally, the snap plate 21 includes a concave mounting cavity, and the heating plate 22 and the heat insulation member 23 are located in the mounting cavity. The mounting cavity is a concave space, the heat insulation member 23 is located at the bottom of the mounting cavity, and the heating plate 22 is located at the opening of the mounting cavity. The mounting cavity can not only limit the mounting positions of the heating plate 22 and the heat insulation member 23, but also keep the heat concentratedly output from the opening of the mounting cavity, control the heat dissipation area, and further improve the heat concentration effect.

[0044] At least two snap ribs 211 are provided on the snap plate 21 and are distributed around the mounting cavity. The at least two snap ribs 211 are snap-connected to the heating kettle body 11. The heating plate 22 and the heat insulation member 23 are located in the mounting cavity. When the snap plate 21 is hooked to the snap groove 111 through the snap ribs 211, the heating plate 22 has a pre-tightening force in the direction towards the heating kettle body 11, further improving the fitting effect between the heating plate 22 and the heating kettle body 11 through the heat conduction pad 30.

[0045] The heating plate assembly 20 includes a clamping ring 40, and the clamping ring 40 tightly clamps and connects the snap plate 21 to the heating kettle body 11. The clamping ring 40 is a ring structure to tightly clamp the snap plate 21, thereby tightly connecting the snap plate 21 and the heating kettle body 11 and not easily loosening. The clamping ring 40 correspondingly clamps at the snap connection part between the snap plate 21 and the heating kettle body 11, thereby preventing the snap plate 21 from being unhooked.

[0046] Further, the heating plate assembly 20 includes a limiting member 50, and the limiting member 50 is installed at the top of the mating portion of the snap disk 21 and the bottom shell assembly 24. The limiting member 50 surrounds the overlapping portion of the bottom shell assembly 24 and the heating kettle body 11 and extends into the mating gap between the snap disk 21 and the heating kettle body 11. The limiting member 50 is of an annular structure. Preferably, at least part of the limiting member 50 is made of an elastic material to achieve elastic support and sealing. For example, the limiting member 50 is made of a silicone material.

[0047] The limiting member 50 is sleeved on the top of the snap disk 21 and the bottom shell assembly 24 to close the mating gap between the snap disk 21 and the bottom shell assembly 24, which can not only prevent water vapor from entering, but also seal the mating gap between the bottom shell assembly 24 and the heating kettle body 11, improving the tightness of the fit.

[0048] Further, the snap disk 21 includes a deformation groove 212 extending from the edge towards the center. The deformation groove 212 locally weakens the snap disk 21, thereby improving the overall elastic deformation effect of the snap disk 21. On the basis of maintaining the axial structural strength, it can expand in the direction of the deformation groove 212, facilitating the heating kettle body 11 to be buckled along the snap rib 211 and resetting after the snap rib 211 is engaged with the snap groove 111, improving the convenience of assembly.

[0049] In a preferred embodiment, the heating plate assembly 20 includes at least one elastic member 27 installed on the snap disk 21, and the at least one elastic member 27 elastically pushes against the heating plate 22 to press tightly against the heat conducting pad 30. Among them, the elastic members 27 are distributed at intervals around the center of the heating plate; or, the elastic members 27 are located at the center of the heating plate to achieve elastic pushing of the heating plate 22. The elastic member 27 can adopt an elastic structure such as a compression spring, a disc spring, a corrugated rubber ring, etc. Preferably, a plurality of elastic members 27 are distributed at intervals around the center of the heating plate, so that the heating plate has an elastic pre-tightening force towards the heating kettle body 11 to push the heat conducting pad 30 to closely adhere to the heating kettle body 11. At the same time, the snap disk 21 receives the elastic pre-tightening force transmitted by the elastic member 27, so that the snap rib 211 is closely engaged with the snap groove 111, making the snap disk 21 and the heating kettle body 11 closely connected and avoiding gaps, abnormal noises and vibrations.

[0050] Preferably, the snap disk 21 is provided with a plurality of positioning columns 213 distributed at intervals, and the elastic member 27 is sleeved on the positioning columns 213 to avoid dislocation. For example, the snap disk 21 is evenly distributed with four, six, eight, ten, or twelve positioning columns 213, and each positioning column 213 is sleeved with a compression spring, and the other end of the compression spring abuts against the heating plate 22.

[0051] Such as Figures 2 to 6As shown, in one embodiment, the kettle body structure 100 includes a water level monitoring component 26 installed on the kettle body assembly 10. The water level monitoring component 26 is used to detect the water level in the heating kettle body 11.

[0052] Furthermore, the kettle body structure 100 includes a water temperature monitoring component 28 installed on the kettle body assembly 10. The water temperature monitoring component 28 is used to detect the water temperature in the heating kettle body 11. The water temperature monitoring component 28 is located at the bottom of the heating kettle body 11 and can output an electrical signal according to the water temperature in the heating kettle body 11, so as to remind the user or control the power on and off.

[0053] Optionally, the kettle body structure 100 can be directly connected to the mains through a wire, or can be used in cooperation with the base device 200.

[0054] As Figure 1 、 Figure 2 and Figure 6 As shown, in one embodiment, the base device 200 disclosed in the above embodiment is applied to a liquid heater. Among them, the liquid heater includes the base device 200 and the kettle body structure 100. The base device 200 is provided with a conductive component 202, and the bottom shell component 24 is erected on the base device 200. The heating plate component 20 is electrically connected to the conductive component 202.

[0055] The base device 200 is connected to the mains through a plug component. The heating plate component 20 is electrically connected to the conductive component 202 through a conductive joint component 25, so as to realize the placement and electrical connection of the kettle body structure 100 on the base device 200. Further preferably, the base device 200 is provided with a charging cavity 201, and the conductive component 202 is located at the bottom of the charging cavity 201.
