In this way, the heat-conducting support 220 is arranged between the support disc 210 and the heating element 230, which can improve the heat transfer efficiency between the heating element 230 and the support disc 210.

[0071] In some embodiments, the heat-conducting support 220 is an aluminum plate, which has good heat-conducting performance and can quickly transfer the heat of the heating element 230 to the aluminum plate and then to the support disc 210.

[0072] In some embodiments, the heating element 230 is a heating tube, and specifically, the heating tube is welded to the aluminum plate, and the aluminum plate is welded to the support disc 210, which has high temperature resistance and is not easy to loosen.

[0073] In some embodiments, the support disc 210 is a stainless steel disc, which has the advantages of good safety, good corrosion resistance, and fast heat transfer.

[0074] In some embodiments, as shown in Figure 1 、 Figure 19 and Figure 20 , the liquid heating container further comprises a heat-conducting pad 60 clamped between the support disc 210 and the container bottom wall 320, and the heat-conducting pad 60 is in contact with the outer side wall of the container bottom wall 320. In this way, the heat-conducting pad 60 can fill the gap between the container bottom wall 320 and the upper surface of the support disc 210, which can improve the heat transfer efficiency and uniformity of the heating assembly 20 to the container body 30, so that the container body 30 is heated more uniformly and at a faster rate.

[0075] Further, as an example, the heat-conducting pad 60 can be made of heat-conducting silica gel or heat-conducting graphite. The heat-conducting silica gel has excellent heat-conducting and insulating properties, and has certain flexibility, can adapt to irregular surfaces, and has good adhesion to most metal and non-metal materials; the heat-conducting graphite is a material with excellent heat-conducting properties, has high thermal conductivity, light weight, good thermal stability, and environmental protection, and the like.

[0076] In some embodiments, as shown in Figure 2 , the container bottom wall 320 is a planar structure; or as shown in Figure 4 , Figure 6 , Figure 8 , Figure 10 and Figure 18 , the container bottom wall 320 is provided with a first protruding portion 321 protruding towards the inside of the container body 30, and the top surface of the first protruding portion 321 is a planar structure; or as shown in Figure 3 , Figure 12 , Figure 14 and Figure 16 , the container bottom wall 320 is provided with a second protruding portion 322 protruding towards the outside of the container body 30, and the bottom surface of the second protruding portion 322 is a planar structure. In this way, the structure of the container bottom wall 320 has multiple choices; wherein the planar structure of the container bottom wall 320 has the advantages of simple structure and stable placement; the first protruding portion 321 protruding inward is arranged on the container bottom wall 320, and the support disc 210 of the heating assembly 20 is arranged in the same shape, which has a convexity protruding into the first protruding portion 321 from the outside of the container bottom wall 320, so that the first protruding portion 321 expands the contact area between the container bottom wall 320 and the heating assembly 20 compared with the planar structure, thereby improving the heat transfer efficiency of the heating assembly 20 to the container bottom wall 320; further, since part of the structure of the heating assembly 20 and the first coupling member 110 protrudes into the first protruding portion 321, the height of the bottom shell 10 occupied by the heating assembly 20 and the first coupling member 110 can be reduced, thereby reducing the height of the bottom shell 10; the second protruding portion 322 protruding outward is arranged on the container bottom wall 320, and the support disc 210 of the heating assembly 20 is arranged in the same shape, which has a groove 211 capable of accommodating the second protruding portion 322, so that the second protruding portion 322 expands the contact area between the container bottom wall 320 and the heating assembly 20 compared with the planar structure, thereby improving the heat transfer efficiency of the heating assembly 20 to the container bottom wall 320.

[0077] In the second embodiment of the present application, as shown in Figure 18 and Figure 19 ​As shown, the lower end of the container side wall 310 is provided with a protruding rib 330 which protrudes outward in the radial direction, and the protruding rib 330 forms the connecting portion. In this way, the protruding rib 330 of the container side wall 310 protrudes outward in the radial direction to form the connecting portion, which is part of the structure of the container side wall 310 and does not need to be additionally provided, thereby simplifying the structure of the container body 30. Compared with the scheme in which the fixing rib 340 serves as the connecting portion, the connecting portion does not need to be additionally welded, so that the processing process of the container body 30 is simpler and the cost is lower. In addition, compared with the concave structure, the protruding rib 330 is less likely to hide dirt, which is conducive to improving the cleanliness and aesthetics of the product.

[0078] Further, in some embodiments, as shown in Figure 18 and Figure 19 , the liquid heating container further comprises a fixing ring 40, the inner side wall of the fixing ring 40 is provided with a recessed portion matched with the protruding rib 330, the fixing ring 40 is sleeved on the protruding rib 330, and the fixing ring 40 is connected with the support disc 210. In this way, the fixing ring 40 is sleeved on the protruding rib 330, the fixing ring 40 can clamp the protruding rib 330, the recessed portion on the fixing ring 40 is matched with the protruding rib 330, and the cooperation of the protruding rib 330 and the recessed portion can increase the connecting strength between the container side wall 310 and the fixing ring 40, so that the container side wall 310 and the fixing ring 40 have connecting force in the axial direction and connecting force in the radial direction, thereby preventing the connection between the two from being loose. Further, the fixing ring 40 is also connected with the support disc 210, thereby realizing the connection between the container body 30, the fixing ring 40 and the support disc 210.

[0079] Further, in some embodiments, as an example, optionally, as shown in Figure 18 and Figure 19 , the fixing ring 40 comprises a ring body sleeved on the protruding rib 330, and a fixing plate connected with the lower end of the ring body and extending towards the support disc 210, and the fixing plate is connected with the support disc 210. As an example, optionally, the fixing plate is located above the support disc 210, the lower surface of the fixing plate is provided with a stud, and the support disc 210 is provided with a threaded hole at a position corresponding to the stud, and a fastener such as a screw or a threaded rod is locked in the stud through the threaded hole.

[0080] In some embodiments, the container body 30 is a glass container body 30, and the wall thickness of the container bottom wall 320 is smaller than the wall thickness of the container side wall 310.

[0081] In these embodiments, the container side wall 310 and the container bottom wall 320 are both made of glass material, which is safe and suitable for containing various solutions, and can be used for cooking tea, porridge, soup and other food materials, and has good safety performance. Moreover, the all-glass container body 30 also has better aesthetics. Further, the wall thickness of the container bottom wall 320 is smaller than that of the container side wall 310. By setting the container bottom wall 320 to be thinner than the container side wall 310, the heat conduction performance of the container bottom wall 320 is better, and heat can be promptly conducted into the container body 30, thereby accelerating the heating of the food material and shortening the cooking time. In addition, by setting the container side wall 310 to be thicker than the container bottom wall 320, the structural strength of the container body 30 is enhanced while the heating effect is ensured, thereby reducing the risk of the container body 30 being broken by impact and improving the reliability and safety of the container body 30 in use.

[0082] In some embodiments, the material of the container body 30 is preferably high borosilicate glass, which has good high-temperature resistance, high mechanical strength and hardness, and can be made into thin-walled but durable glass products, which are suitable for products that need to withstand certain pressure or impact force.

[0083] In some embodiments, the thickness of the container side wall 310 is greater than 3 mm and less than or equal to 5 mm. Within this range, on the one hand, the problem of the container side wall 310 being easily broken in use due to its small structural strength is avoided, and on the other hand, the problem of the container body 30 being too heavy due to the large thickness of the container side wall 310 is also avoided, which is inconvenient for users to use, increases unnecessary material investment, and causes material waste.

[0084] In some embodiments, the thickness of the container bottom wall 320 is greater than or equal to 3 mm and less than or equal to 4 mm. Within this range, on the one hand, the problem of the container bottom wall 320 being easily broken in use due to its small thickness is avoided, and on the other hand, the problem of the container bottom wall 320 having poor heat conduction performance due to its large thickness, which causes slow heating efficiency, is also avoided. Moreover, the thick container bottom wall 320 also causes the container body 30 to be too heavy, which is inconvenient for users to use, increases unnecessary material investment, and causes material waste.

[0085] In some embodiments, in the case where the thickness of the container bottom wall 320 is different from that of the container side wall 310, the container body 30 is a tube glass container. By setting the thickness of the container side wall 310 to be different from that of the container bottom wall 320, the tube glass forming process can be used to achieve the different thicknesses of the container side wall 310 and the container bottom wall 320, and the tube glass has the advantages of high transparency, chemical stability, high temperature and pressure resistance, high mechanical strength, etc.

[0086] In some embodiments, as shown in FIG. 1, the container body 30 is a tube glass container, and the container side wall 310 and the container bottom wall 320 have different thicknesses. Figure 1 and Figure 21As shown in the drawings, the liquid heating container further comprises a handle 50 connected with the container body 30, the upper end of the handle 50 is clamped at the top end of the container side wall 310, or a handle 50 fixing ring is sleeved on the upper end of the container body 30, the upper end of the handle 50 is connected with the handle 50 fixing ring through a screw, and the lower end of the handle 50 is connected with the bottom shell 10. In this way, the container body 30 can be taken by the handle 50, so that the taking and placing of the container body 30 is more convenient.

[0087] In some embodiments, as shown in Figure 1 、 Figure 19 and Figure 21 , the liquid heating container further comprises a lid 70 covering the container mouth of the container body 30.

[0088] In some embodiments, as shown in Figure 1 , the liquid heating container further comprises a base 80, the base 80 is provided with a second coupling part 810 matched with the first coupling part 110, when the bottom shell 10 is placed on the base 80, the first coupling part 110 and the second coupling part 810 are inserted and matched, so that the electric elements such as the heating element 230 in the bottom shell 10 are powered on.

[0089] In some embodiments, the liquid heating container can be an electric kettle, a health pot, a coffee pot and the like.
