[0001] The present application relates to the technical field of drinking water appliances, and particularly relates to a liquid heating container. BACKGROUND

[0002] The liquid heating container usually comprises an inner container and a heating disc. The inner container is used for containing liquid, and the heating disc is connected with an electric circuit. The heating disc converts electric energy into heat to heat the liquid. Generally, the heating disc is fixedly connected to the bottom of the inner container, which makes the liquid heating container inconvenient to clean. In addition, during the heating process, the heat generated by the heating disc is first transferred to the inner container and then to the liquid through the inner container, which results in a large heat loss and affects the heating efficiency. CONTENT OF THE UTILITY MODEL

[0003] The present application provides a liquid heating container to provide a liquid heating container with high heating efficiency and convenient cleaning.

[0004] The liquid heating container provided by the present application comprises:

[0005] An outer shell comprising a first cavity with an upward opening;

[0006] A heating disc arranged in the first cavity;

[0007] An inner container arranged above the heating disc and detachably connected with the outer shell. The bottom of the inner container is provided with a heating hole penetrating through the inner container along the thickness direction.

[0008] When the inner container is fixedly connected with the outer shell, the heating hole is closed by the heating disc, and the inner container and the heating disc jointly form a sealed cavity for containing liquid.

[0009] The liquid heating container provided by the present application comprises an outer shell, a heating disc and an inner container. The outer shell comprises a first cavity with an upward opening. The heating disc is arranged in the first cavity. The inner container is arranged above the heating disc. The inner container is detachably connected with the outer shell. The bottom of the inner container is provided with a heating hole penetrating through the inner container along the thickness direction. When the inner container is fixedly connected with the outer shell, the heating hole is closed by the heating disc, and the inner container and the heating disc jointly form a sealed cavity for containing liquid. Thus, the liquid can directly contact the heating disc, the heat loss is reduced, and the heating efficiency is improved. In addition, the inner container is detachably connected and fixed, which facilitates the disassembly and cleaning of the inner container, improves the cleanliness of the liquid heating container, and improves the use experience of the liquid heating container. The inner container is fixedly connected with the outer shell, and the outer shell provides support and fixing force for the inner container. Thus, only the extrusion force of contact sealing exists between the heating disc and the inner container, which prevents the deformation or rupture of the heating disc caused by repeated disassembly and assembly of the inner container, and prolongs the service life of the liquid heating container.

[0010] Optionally, the upper surface of the heating disc is provided with a first annular protrusion opposite to the heating hole, and an outer periphery of the first annular protrusion is sleeved with a sealing ring in sealing cooperation with the lower surface of the inner container. On the one hand, the first annular protrusion and the heating disc form a heating groove therebetween, and the liquid is heated in the smaller heating groove, so that the heat is more concentrated, the heat diffusion loss is reduced, and rapid heating can be achieved by smaller heating power; on the other hand, under the action of the axial extrusion force, the sealing ring is in sealing cooperation with the end surface of the heating hole, which can increase the sealing cooperation area and increase the reliability of the sealing cooperation, and by adjusting the axial extrusion force, the reliability of the sealing cooperation can be ensured, and the service life of the liquid heating container can be prolonged.

[0011] Optionally, the upper surface of the heating disc is provided with a second annular protrusion concentrically arranged at the outer ring of the first annular protrusion, and the second annular protrusion and the first annular protrusion form an annular groove therebetween, and the sealing ring is arranged in the annular groove. The inner and outer annular protrusions limit the radial deformation of the sealing ring, reduce or avoid the radial deformation of the sealing ring, and make the sealing ring deform as much as possible in the axial direction, so that the elastic force of the sealing ring in the axial direction can be increased, and the sealing effect can be further improved.

[0012] Optionally, the sealing ring comprises: a main body portion embedded in the annular groove, the thickness of the main body portion being less than the depth of the annular groove; two sealing protrusions protruding from the upper side of the main body portion, the sealing protrusions being in sealing cooperation with the lower surface of the inner container, and the two sealing protrusions being provided with a gap on the side close to each other and abutting against the first annular protrusion and the second annular protrusion on the side away from each other. The main body portion and the annular groove cooperate with each other to position and fix the sealing ring, prevent the sealing ring from being twisted or displaced abnormally, affect the sealing cooperation between the sealing ring and the inner container, and isolate the sealing ring in the annular groove as much as possible to reduce the exposure of the sealing ring, thereby reducing or avoiding the direct contact between the sealing ring and the liquid; the two sealing protrusions form two independent seals, effectively reducing the risk of leakage of the liquid heating container, and the first annular protrusion and the second annular protrusion laterally support the sealing protrusions, reduce the lateral bending of the sealing protrusions, and increase the reliability of the sealing cooperation.

[0013] Optionally, the diameter of the heating hole is 20mm-30mm, which can realize rapid heating and reliable sealing effect.

[0014] Optionally, the bottom of the first cavity is provided with a threaded hole, the heating disc is provided with a through hole corresponding to the threaded hole, and the liquid heating container further comprises: a first nut arranged between the through hole and the threaded hole; a second nut arranged at the end of the threaded hole away from the through hole; and a bolt penetrating through the through hole and sequentially connected to the first nut, the threaded hole and the second nut. Thus, the height of the heating disc can be adjusted, and the heating disc can be stably and reliably locked at the expected height, so that reliable sealing cooperation between the heating disc and the inner container can be formed.

[0015] Optionally, the shell further comprises a second cavity with an opening facing one side, and the second cavity is located below the first cavity; and the liquid heating container further comprises a battery box which is detachably connected to the second cavity. Thus, the liquid heating container can be heated by weak electricity, and the demand for outdoor use of the liquid heating container can be met. Moreover, the battery box is mounted and detached from one side of the liquid heating container, and the liquid heating container does not need to be lifted when the battery box is detached, so that the operation is more convenient.

[0016] Optionally, the outer edge of the mouth of the inner container is exposed to the top of the shell, the outer side wall of the shell is provided with a protrusion, and the liquid heating container further comprises a connecting piece which is hinged to the outer edge of the mouth and can be flipped in the up-down direction to lock or unlock the connecting piece with the protrusion. The user only needs to flip the connecting piece up and down to lock or unlock the inner container, so that the disassembly and assembly of the inner container are simplified. Moreover, the connecting piece is exposed to the top of the shell, and the user operates the connecting piece on the top of the shell, so that the operation space is larger and the user is less likely to be scalded. In addition, the connecting piece is close to the top of the inner container, so that the whole inner container is stressed, the shaking or vibration of the inner container can be reduced, the stability of the inner container is increased, and the reliability of the sealing cooperation is increased.

[0017] Optionally, the top of the shell is provided with an insertion part which is covered with a flexible piece; the mouth of the inner container is provided with an outward-turned edge which surrounds an insertion slot with an opening downward between the outward-turned edge and the inner container; the insertion part is inserted into the insertion slot; and the flexible piece separates the insertion part and the insertion slot from each other. Thus, the inner container can be reliably positioned to prevent the inner container from shaking in the shell, and the inner container has flexible floating spaces in the radial direction and the axial direction, so that the influence of the machining error and the assembly error is reduced.

[0018] Optionally, the connecting piece comprises a connecting part, two arm parts are respectively arranged at the two ends of the connecting part in the length direction of the connecting part, and one end of each arm part away from the connecting part is hinged to the edge of the mouth. When the connecting piece is locked with the protrusion, the connecting part is hung on the lower side of the protrusion, so that the protrusion can provide a downward force to the connecting part as a whole, and the reliability of the connection between the connecting piece and the protrusion is increased.

[0019] It should be understood that the general description and the following detailed description are only exemplary and do not limit the present application. BRIEF DESCRIPTION OF DRAWINGS

[0056] The accompanying drawings, which are incorporated herein and constitute part of this specification, illustrate embodiments consistent with the application and serve to explain the principles of the application. DETAILED DESCRIPTION

[0057] In order to make the purposes, technical solutions and advantages of the application clearer, the application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the application and not to limit the application.

[0058] In the description of the application, unless explicitly defined and limited, the terms "first", "second" are only used for the purpose of description, and cannot be understood as indicating or implying relative importance; unless otherwise specified or explained, the term "multiple" means two or more; the terms "connection", "fixation" and the like should be understood in a broad sense, for example, "connection" can be fixed connection, can also be detachable connection, or integral connection, or electrical connection; can be directly connected, or indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the application can be understood according to the specific circumstances.

[0059] In the description of the specification, it needs to be understood that the "upper", "lower" and other orientation words described in the embodiments of the application are described in the angle shown in the drawings, and should not be understood as the limitation of the embodiments of the application. In addition, in the context, it also needs to be understood that when referring to one element connected to another element "on" or "under", it can not only be directly connected to another element "on" or "under", but also indirectly connected to another element "on" or "under" through an intermediate element.

[0060] As shown in Figure 1 and Figure 2 The embodiments of the application provide a liquid heating container, which comprises a shell 1, a heating disc 2 and an inner container 3. The shell 1 constitutes the external form of the liquid heating container, and the shell 1 can be made of a heat insulation material such as plastic. The shell 1 comprises a first cavity 11 which is open upward. The heating disc 2 can contain a heating element such as PTC to convert electrical energy into heat. The heating disc 2 is arranged in the first cavity 11, so that the shell 1 plays a role of supporting, protecting and heat insulating the heating disc 2. The inner container 3 is arranged above the heating disc 2 and detachably connected with the shell 1. The bottom of the inner container 3 is provided with a heating hole 31 which penetrates the inner container 3 along the thickness direction. When the inner container 3 is connected and fixed to the shell 1, the heating disc 2 closes the heating hole 31. The heating disc 2 and the inner container 3 jointly form a sealed cavity for containing liquid, so that the liquid can directly contact the heating disc 2, reducing heat loss and improving heating efficiency. In addition, the inner container 3 is connected and fixed in a detachable manner, which can facilitate the disassembly and cleaning of the inner container 3, improve the cleanliness of the liquid heating container and improve the use experience of the liquid heating container. The inner container 3 is connected and fixed to the shell 1, and the shell 1 provides a supporting and fixing force to the inner container 3. Therefore, only a contact sealing extrusion force exists between the heating disc 2 and the inner container 3, so that the damage of the heating disc 2 caused by repeated disassembly and assembly of the inner container 3 can be prevented, and the service life of the liquid heating container is prolonged.

[0061] Specifically, the heating hole 31 is arranged within the contour of the heating disc 2, so that the heating disc 2 can completely cover and close the heating hole 31. A sealing ring 23 can be arranged between the heating disc 2 and the inner container 3. The sealing ring 23 can be any sealing ring 23 with elasticity and meeting the food hygiene requirements, such as an O-ring. The sealing ring 23 surrounds the heating hole 31, for example, the sealing ring 23 is in sealing cooperation with the hole wall of the heating hole 31, or the sealing ring 23 is in sealing cooperation with the end surface of the heating hole 31, so as to prevent the liquid from leaking from the heating hole 31.

[0062] A power switch 16 can be installed on the outer shell 1 to control the liquid heating container to start or stop heating. A bracket 112 can be installed at the bottom of the first cavity 11, and the heating plate 2 is connected and fixed to the bracket 112. The bracket 112 can be integrally formed with the outer shell 1, or it can be connected to the outer shell 1 by screws or other means. The liquid heating container may also include a container lid 8, which covers the opening of the inner liner 3 to reduce heat loss and improve heating efficiency.

[0063] Furthermore, the outer casing 1 also includes a second cavity 12 with an opening facing one side, located below the first cavity 11. The liquid heating container also includes a battery box 7, which houses a primary or rechargeable battery and is detachably connected to the second cavity 12. This allows the liquid heating container to be heated by low-voltage electricity, meeting the needs of outdoor use. Moreover, the battery box 7 can be installed and removed from one side of the liquid heating container, eliminating the need to lift the container during installation and removal, making operation simpler.

[0064] like Figures 1-4 As shown, the outer edge of the opening of the inner liner 3 is exposed on the top of the outer shell 1, and a protrusion 13 is provided on the outer side wall of the outer shell 1. The liquid heating container also includes a connector 33, which is hinged to the outer edge of the opening and can be rotated vertically to lock or unlock the connector 33 and the protrusion 13. The user only needs to rotate the connector 33 vertically to lock or release the inner liner 3, simplifying the disassembly and assembly of the inner liner 3. Furthermore, since the connector 33 is exposed on the top of the outer shell 1, the user can operate the connector 33 from the top of the outer shell 1, providing a large operating space and reducing the risk of burns. In addition, the connector 33 is close to the top of the inner liner 3, so that the inner liner 3 is subjected to force as a whole, which can reduce the shaking or vibration of the inner liner 3, increase the stability of the inner liner 3, and thus increase the reliability of the sealing fit.

[0065] Furthermore, the connector 33 includes a connecting portion 331, with an arm 332 at each end along its length. The end of the arm 332 away from the connecting portion 331 is hinged to the edge of the opening. When the connector 33 and the protrusion 13 are locked, the connecting portion 331 is hooked onto the lower side of the protrusion 13, thereby allowing the protrusion 13 as a whole to provide a downward force on the connecting portion 331, increasing the reliability of the connection between the connector 33 and the protrusion 13.

[0066] Furthermore, the top of the outer shell 1 is provided with an annular insertion portion 14, which is covered by a flexible element 15 with an inverted U-shaped cross-section. The opening of the inner liner 3 is provided with an outwardly flanged edge 32, which forms a downward-opening slot 34 with the inner liner 3. The insertion portion 14 is inserted into the slot 34, and the flexible element 15 separates the insertion portion 14 from the slot 34. That is, the flexible element 15 fills the gap between the insertion portion 14 and the slot 34. This not only provides reliable positioning for the inner liner 3, preventing it from shaking inside the outer shell 1, but also allows the inner liner 3 to have flexible floating space in both the radial and axial directions, reducing the impact of processing and assembly errors.

[0067] like Figures 5-7 As shown, the upper surface of the heating plate 2 has a first annular protrusion 21 facing the heating hole 31. The outer diameter of the first annular protrusion 21 is not less than the diameter D of the heating hole 31. A sealing ring 23 is fitted around the outer periphery of the first annular protrusion 21, and the sealing ring 23 is in a sealing fit with the lower surface of the inner liner 3. On the one hand, the first annular protrusion 21 and the heating plate 2 form a heating groove. The liquid is heated in a smaller heating groove, which can concentrate the heat more and reduce the heat diffusion loss, thereby achieving rapid heating with a smaller heating power. On the other hand, under the action of axial extrusion force, the sealing ring 23 and the end face of the heating hole 31 form a sealing fit, which can increase the sealing fit area and increase the reliability of the sealing fit. It can also ensure the reliability of the sealing fit by adjusting the axial extrusion force, thus extending the service life of the liquid heating container.

[0068] Furthermore, the upper surface of the heating plate 2 is provided with a second annular protrusion 22, which is concentrically arranged around the outer ring of the first annular protrusion 21. An annular groove is formed between the second annular protrusion 22 and the first annular protrusion 21, and the sealing ring 23 is disposed in the annular groove. The inner and outer annular protrusions provide radial limiting for the sealing ring 23, reducing or avoiding radial deformation of the sealing ring 23, and allowing the sealing ring 23 to deform as much as possible along the axial direction. This increases the elastic force of the sealing ring 23 along the axial direction, further improving the sealing effect.

[0069] Furthermore, the sealing ring 23 includes a main body 231 and two sealing ribs 232. The sealing ribs 232 protrude from the upper side of the main body 231 and are in a sealing fit with the lower surface of the inner liner 3. The main body 231 is fitted into the annular groove, and the thickness of the main body 231 is less than the depth of the annular groove. This not only positions and fixes the sealing ring 23, preventing abnormalities such as torsion or displacement of the sealing ring 23 that would affect the sealing fit between the sealing ring 23 and the inner liner 3, but also isolates the sealing ring 23 as much as possible within the annular groove, reducing the exposure of the sealing ring 23 and thus reducing or avoiding direct contact between the sealing ring 23 and the liquid. The two sealing ribs 232 are spaced apart on their adjacent sides, forming two independent seals, effectively reducing the risk of leakage from the liquid heating container. The two sealing ribs 232 are positioned opposite each other and abut against the first annular protrusion 21 and the second annular protrusion 22 respectively, thereby providing lateral support to the sealing ribs 232, reducing the lateral bending of the sealing ribs 232, and increasing the reliability of the sealing fit.

[0070] Furthermore, the top of the sealing rib 232 is a flat surface, through which the sealing rib 232 contacts the lower surface of the inner liner 3. This increases the contact area between the sealing rib 232 and the inner liner 3, thereby increasing the reliability of the sealing fit, and also makes the sealing rib 232 more evenly stressed, thus preventing abnormalities such as lateral bending of the sealing rib 232.

[0071] Furthermore, the diameter D of the heating hole 31 is 20mm to 30mm. For example, the diameter D of the heating hole 31 can be 20mm, 21mm, 22mm, 23mm, 24mm, 25mm, 26mm, 27mm, 28mm, 29mm, or 30mm, etc., which can achieve both rapid heating and easy reliable sealing. When the diameter D of the heating hole 31 is less than 20mm, the heat is too concentrated, which can easily lead to abnormalities such as local overheating; when the diameter D of the heating hole 31 is greater than 30mm, the sealing area is too large, making sealing more difficult and prone to abnormalities such as water leakage.

[0072] Furthermore, the bottom of the first cavity 11 (e.g., on the bracket 112) is provided with a threaded hole 111, and the heating plate 2 is provided with a through hole 24 corresponding to the threaded hole 111. The liquid heating container also includes a first nut 4, a second nut 5, and a bolt 6. The first nut 4 is disposed between the through hole 24 and the threaded hole 111, the second nut 5 is disposed at the end of the threaded hole 111 away from the through hole 24, and the bolt 6 passes through the through hole 24 and is sequentially connected to the first nut 4, the threaded hole 111, and the second nut 5, thereby adjusting the height of the heating plate 2 and reliably locking the heating plate 2 at the expected height, so that a reliable sealing fit can be formed between the heating plate 2 and the inner liner 3.

[0073] Specifically, the first nut 4 is used to lock or loosen the heating plate 2. That is, when the first nut 4 is tightened, it abuts against the lower surface of the heating plate 2, and the heating plate 2 is locked between the nut and the first nut 4. The second nut 5 is used to lock or loosen the bolt 6. That is, when the second nut 5 is tightened, it abuts against the bottom of the bracket 112, and the bolt 6 is locked. When both the first nut 4 and the second nut 5 are loosened, the bolt 6 can be screwed into or out of the threaded hole 111, thereby adjusting the height of the bolt 6 to create upward or downward space for the heating plate 2. When the bolt 6 is adjusted to the correct position (i.e., the heating plate 2 and the inner liner 3 can form a sealing fit), tightening the first nut 4 and the second nut 5 ensures that the heating plate 2 is stably and reliably maintained at the expected height, preventing the sealing from failing due to loosening of the heating plate 2 during use.

[0074] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
