Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0029] The following is combined Figures 1 to 6 This application describes a liquid heating container.

[0030] A liquid heating container according to an embodiment of this application is provided, please refer to... Figures 1 to 4 The liquid heating container includes a container body 100, which includes a body 110 and a bottom structure 120. The body 110 includes a neck structure 111 and a mounting part 112, with the mounting part 112 connected to the neck structure 111. The bottom structure 120 includes a first bottom plate 1212, a first side wall 1211, a second bottom plate 1214, and a second side wall 1213. The second side wall 1213 is located outside the first side wall 1211. The first side wall 1211 is connected to the first bottom plate 1212. The first side wall 1211, the second bottom plate 1214, and the second side wall 1213 are connected to form a mating groove 1230. The mounting part 112 is inserted into the mating groove 1230. The minimum inner diameter of the neck structure 111 is less than or equal to the inner diameter of the first side wall 1211.

[0031] According to the liquid heating container of this application, the traditional method of combining the bottom and body 110 of a liquid heating container by adhesive bonding is changed. By inserting the lower end of the body 110 into the mating groove 1230, the body 110 and the bottom structure 120 form a layered fit on the side of the liquid heating container, which completely eliminates the possibility of glue gaps in the bottom of the traditional liquid heating container. The minimum inner diameter of the neck structure 111 is less than or equal to the inner diameter of the first side wall 1211, which can effectively block the mating groove 1230. When liquid is poured into the container or food is placed in it, due to the restriction of the neck structure 111, it is difficult for the liquid or food to enter the mating groove 1230 from the side during the flow or placement process.

[0032] It is understandable that the first sidewall 1211 is connected to the first base plate 1212 and surrounds the first base plate 1212. The first base plate 1212 is the bottom plane of the bottom structure 120. During use, it will come into contact with the heating source and play a role in conducting heat.

[0033] The second sidewall 1213 is fixedly connected to the first sidewall 1211 via the second base plate 1214. A vertically extending mating groove 1230 is formed between the second sidewall 1213, the second base plate 1214, and the first sidewall 1211. The shape and size of the mating groove 1230 can be carefully designed according to the specifications of the kettle body 110 to ensure a tight fit after the kettle body 110 is inserted, without any loosening. Of course, in some possible embodiments, the mating groove 1230 can be filled with a gel-like substance, which achieves a fixed connection and seal between the bottom structure 120 and the kettle body 110.

[0034] The body 110 is the part used to hold liquid, and its lower end is designed to be inserted into the mating groove 1230. When assembling the liquid heating container, the lower end of the body 110 must be inserted vertically into the mating groove 1230.

[0035] It should be noted that the side-connection method used in this application is completely different from the traditional method of directly bonding the bottom and body 110 of a liquid heating container. In this application, the liquid heating container uses a mating groove 1230 inserted into the lower end of the body 110, allowing the body 110 and the bottom structure 120 to form a layered fit on the side of the liquid heating container. This layered fit completely eliminates the problem of glue gaps at the bottom of traditional liquid heating containers, improving the hygiene performance of the container and allowing users to use it with greater peace of mind.

[0036] In one embodiment, the minimum inner diameter of the neck structure 111 is less than or equal to the maximum inner diameter of the first sidewall 1211. For example, if the first sidewall 1211 is a slope or an arc surface, the minimum inner diameter of the neck structure 111 being less than or equal to the maximum inner diameter of the first sidewall 1211 can ensure that the neck structure 111 blocks the mating groove 1230.

[0037] According to one embodiment of this application, the first base plate 1212 is lower than the second base plate 1214 along the vertical direction. In the application of liquid heating containers, especially for glass containers, thermal expansion and contraction is a key concern. Glass, as a common container material, exhibits the physical property of thermal expansion and contraction. When a liquid heating container is heated, the bottom of the container is in direct contact with the heat source, such as a heating plate, causing the bottom temperature to rise rapidly. The upper part of the container, being farther from the heat source, experiences a relatively slower temperature rise, thus creating a temperature difference inside the container.

[0038] This temperature difference causes different parts of the glass container to expand at different rates. If the first base plate 1212 and the second base plate 1214 are at the same level, they will be subjected to the same thermal stress during thermal expansion and contraction. Because the components in the bottom structure 120 are tightly connected, these thermal stresses are difficult to release effectively and will gradually accumulate at the joints or inside the glass. When the accumulated stress exceeds the glass's tolerance limit, cracks will appear in the glass, and in severe cases, it may even shatter, causing not only liquid leakage but also potential injury to the user.

[0039] In this embodiment, during thermal expansion and contraction, the first base plate 1212 and the second base plate 1214, due to their different positions, will expand or contract in different directions and to different degrees. This difference allows thermal stress to be dispersed and alleviated to a certain extent, preventing stress concentration in a particular area. For example, during heating, the first base plate 1212 heats up faster and expands relatively more, while the second base plate 1214 heats up more slowly and expands less. This difference between the two prevents excessive stress concentration at the joint, thereby reducing the possibility of the glass cup cracking due to thermal expansion and contraction. This design effectively improves the safety and service life of glass liquid heating containers, providing users with a more reliable user experience.

[0040] In one embodiment, the height difference between the first base plate 1212 and the second base plate 1214 is H1, where H1 is 1mm-8mm.

[0041] According to one embodiment of this application, the mating groove 1230 is adapted to be filled with a gel-like substance to seal the gap between the lower end of the body 110 and the bottom structure 120.

[0042] In practical applications, after the lower end of the kettle body 110 is inserted into the mating groove 1230 to complete the initial connection, there may still be some tiny gaps that are difficult to detect with the naked eye between the kettle body 110 and the bottom structure 120. These gaps may cause a series of problems during the liquid heating process. For example, when the liquid expands due to heat, the pressure increases, and the liquid may seep out from these gaps. This not only wastes the liquid but may also damage the surface on which the container is placed. In extreme cases, if the leaked liquid comes into contact with the heating source, it may even cause a safety accident.

[0043] To address these issues, this embodiment employs a method of filling the mating tank 1230 with a gel-like substance. When selecting the gel-like substance, factors such as its adhesion, sealing properties, and high-temperature resistance are comprehensively considered. For example, silicone sealant is a commonly used gel-like substance. It possesses excellent adhesion and sealing properties, and after curing, it forms a soft and elastic sealing layer, effectively filling gaps. Simultaneously, silicone sealant also exhibits a certain degree of high-temperature resistance, capable of withstanding the high temperatures generated during liquid heating without losing its sealing effect due to temperature increases.

[0044] Of course, other gel-like substances can be used besides silicone sealant; no specific restrictions are made here.

[0045] When filling the gel-like substance, a specialized filling tool can be used to evenly fill the mating groove 1230, ensuring that every part of the gap is fully filled. After filling, and after a period of curing, the gel-like substance will form a stable sealing layer, completely sealing the gap between the lower end of the body 110 and the bottom structure 120.

[0046] By filling the gap with a gel-like substance in the mating groove 1230 to seal the gap, the liquid heating container of this application not only retains the advantages of the original layered mating structure, such as eliminating the gap of hidden glue, improving hygiene performance and connection stability, but also further solves the possible liquid leakage problem, improves the safety and reliability of the container, and provides users with a better and more reliable user experience.

[0047] According to one embodiment of this application, along the vertical direction, the upper edge of the second sidewall is equal to or higher than the upper edge of the first sidewall. When assembling the pot body, the silicone sealant moves upwards, first filling the gap between the first sidewall 1211 and the mounting portion 112, preventing water or food from accumulating in this gap during later use.

[0048] In one embodiment, the height difference between the upper edge of the second sidewall 1213 and the upper edge of the first sidewall 1211 is H2, where H2 is 1mm-3mm.

[0049] According to one embodiment of this application, the first sidewall 1211 and the first base plate 1212 are integrally formed.

[0050] In the traditional field of liquid heating vessel manufacturing, the first base plate 1212 and the first sidewall 1211 are usually manufactured separately. These two independent components are first fabricated, and then joined together using welding, bonding, or other assembly methods. However, this traditional manufacturing method has many problems. During assembly, due to factors such as machining precision and assembly processes, it is difficult to ensure a completely tight fit between the first base plate 1212 and the first sidewall 1211, inevitably leaving some gaps. These gaps may seem small, but they can have serious consequences in actual use.

[0051] These crevices provide a breeding ground for bacteria, which can easily hide and multiply in them. Because the crevices are narrow, they are very difficult to clean, and long-term use of such containers can have adverse effects on the user's health.

[0052] To address these issues, this embodiment integrates the first sidewall 1211 and the first base plate 1212, as well as the second base plate 1214 and the second sidewall 1213. Structurally, there is no gap between the first base plate 1212 and the first sidewall 1211, completely eliminating the risk of liquid leakage and bacterial growth. Regardless of the external force applied to the container or the usage environment, excellent sealing performance is guaranteed, ensuring that liquid will not leak from the bottom. Simultaneously, the seamless structure makes cleaning easier; users can clean the saucer using conventional cleaning methods, effectively ensuring the hygiene of the container.

[0053] In this embodiment, the first sidewall 1211 is located on the inner side and plays an important role in directly connecting with the key part of the lower end of the kettle body 110, thus providing positioning and initial support. The second sidewall 1213 is located on the outer side and works in conjunction with the first sidewall 1211 to surround and reinforce the connection part from the outside, forming a stable connection environment and effectively preventing the kettle body 110 from shaking or falling off due to external forces during use.

[0054] The lower end of the kettle body 110 is provided with a neck structure 111 that tapers inward and a mounting portion 112. The inward taper of the neck structure 111 changes the shape of the lower end of the kettle body 110, allowing the mounting portion 112 to be more prominent or have a specific geometric shape. This design not only enhances the structural strength of the lower end of the kettle body 110 but also facilitates the connection with the first side wall 1211. The mounting portion 112 partially inserts into a mating groove 1230, which is a space specifically reserved for the mounting portion 112, and its shape and size precisely match the mounting portion 112. When the mounting portion 112 is inserted into the mating groove 1230, a fit is formed between the two. At the same time, the mating groove 1230 also serves as a guide and positioning tool. During assembly, the operator only needs to align the lower end of the kettle body 110 with the mating groove 1230 to easily achieve accurate insertion, greatly improving the efficiency and precision of assembly.

[0055] According to one embodiment of this application, the first base plate, the second base plate, and the second sidewall are integrally formed.

[0056] According to one embodiment of this application, please refer to Figure 1 and Figure 6 A sealing ring 500 is provided between the first side wall 1211 and the lower end of the body 110, and the neck structure 111 part abuts against the sealing ring 500.

[0057] The sealing ring 500 can be made of a material with excellent elasticity and flexibility, such as rubber. When installed between the first side wall 1211 and the lower end of the body 110, it can deform appropriately due to its own elasticity, fit tightly against the surfaces of the first side wall 1211 and the lower end of the body 110, fill the tiny gap between them, and form a reliable and tight sealing barrier.

[0058] From a sealing perspective, when the container is statically filled with liquid, the sealing ring 500 provides a static seal, effectively preventing liquid leakage from the connection points and ensuring stable storage of the liquid inside the container. The sealing ring 500 works closely with the connection structures of the neck structure 111, the mounting portion 112, and the first sidewall 1211 to form a complete sealing system. The sealing ring 500 can further fill any possible tiny gaps, enhancing the sealing effect.

[0059] According to one embodiment of this application, the height of the second sidewall 1213 along the vertical direction is equal to or higher than the height of the first sidewall 1211 along the vertical direction.

[0060] The height of the second sidewall 1213 in the vertical direction is equal to or higher than the height of the first sidewall 1211 in the vertical direction. It is used to guide the silicone sealant to fill the assembly gap between the lower end of the pot body 110 and the first sidewall 1211 during the assembly process, eliminating liquid residue space. This allows the silicone sealant to be squeezed and preferentially move upward to fill the assembly gap between the lower end of the pot body 110 and the first sidewall 1211 during the assembly of the pot body 110, forming a continuous sealing interface and preventing liquid or food residue from accumulating in the gap during use.

[0061] According to one embodiment of this application, the distance between the first sidewall 1211 and the second sidewall 1213 is d, where d is greater than 3 mm.

[0062] If the distance d is too small, on the one hand, the heating plate and the bottom of the glass may interfere with each other during assembly due to manufacturing errors or assembly deviations, causing the bottom of the glass to be subjected to additional mechanical stress; on the other hand, the heat transfer is too concentrated during heating, and the bottom of the glass cannot dissipate heat evenly in time, resulting in excessively high local temperatures and a large temperature difference with other parts, which in turn generates thermal stress that exceeds the glass's tolerance limit, causing the glass to break.

[0063] In one embodiment, the size of d is 6-7 mm.

[0064] Silicone sealant is used to fill the assembly gap between the lower end of the vessel body 110 and the first sidewall 1211 to form a sealing interface. If the distance d is too large, too much silicone sealant needs to be used to ensure a good seal, which not only increases material costs but also affects assembly efficiency and sealing quality due to uneven application and dripping. In practical applications, a distance of 6-7mm is preferred, providing a buffer space for the bottom of the glass, allowing heat to be transferred and diffused more evenly, reducing the concentration of thermal and mechanical stress, effectively avoiding the risk of glass breakage, and allowing for reasonable control of silicone sealant usage while ensuring a good seal, thus optimizing cost and performance.

[0065] According to one embodiment of this application, a liquid heating container includes a heating element 200, which is connected to a bottom structure 120.

[0066] The heating element 200 is connected to the bottom structure 120. This connection method ensures the stability of the heating element 200 during container use.

[0067] In one embodiment, the heating element 200 is bonded to the first base plate 1212 using silicone adhesive. Silicone adhesive has excellent bonding properties, enabling it to firmly bond the heating element 200 to the first base plate 1212.

[0068] In one embodiment, the heating element 200 is provided with electronic devices such as a heating tube and a temperature sensor.

[0069] In one embodiment, the liquid heating container includes an aluminum plate 400 disposed between the heating element 200 and the bottom structure 120. The aluminum plate 400 is used to increase the heating area. The heating element 200 transfers heat to the aluminum plate 400, and the aluminum plate 400 can disperse the heat to various locations on the aluminum plate 400, thereby increasing the heating area.

[0070] According to one embodiment of this application, the liquid heating container includes a container shell 300, which is fixedly connected to the container body 100, and the bottom structure 120 is located inside the container shell 300.

[0071] The outer shell 300 protects the bottom structure 120 and provides a stable space for the assembly of the body 110 and the saucer.

[0072] In one embodiment, the container shell 300 is attached to the neck structure 111.

[0073] Finally, it should be noted that the above embodiments are only used to illustrate this application and are not intended to limit this application. Although this application has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of this application do not depart from the spirit and scope of the technical solutions of this application and should be covered within the scope of the claims of this application.
