Description

Technical Field

[0001] The invention relates to the field of containers, and in particular to a liquid heating container. Background Art

[0002] The health pot structure in the prior art includes a container cover, a container body, a heating plate assembly, an upper coupler, a bottom shell and a base. The bottom shell is connected to the lower end of the container body and encloses a receiving cavity, the upper coupler and the heating plate assembly are both arranged in the receiving cavity, and the upper coupling piece is located between the heating plate assembly and the bottom wall of the bottom shell. The upper coupler of the above structure needs to occupy a large axial height of the bottom shell, resulting in a high height of the bottom shell, which affects the user's storage and visual appearance. Summary of the invention

[0003] Therefore, an object of the present invention is to provide a liquid heating container to solve at least one of the problems existing in the above-mentioned prior art or related art.

[0004] The first aspect of the present invention provides a liquid heating container, comprising: a bottom shell, in which a heating component and a first coupling member are arranged; a container body, which is connected to the bottom shell, and the container body comprises a container side wall and a container bottom wall, and the container bottom wall comprises a protruding area protruding toward the interior of the container body, and a accommodating cavity capable of accommodating the heating component and the first coupling member is formed between the lower surface of the protruding area and the bottom shell.

[0005] The liquid heating container provided in the embodiment of this aspect has a bottom wall that protrudes toward the inside of the container body to form an inwardly convex structure, and the heating component and the first coupling component are hidden between the protruding area and the bottom wall of the bottom shell. The setting of the protruding area can provide partial accommodation space for the heating component and the first coupling component, thereby reducing the axial height of the bottom shell occupied by the heating component and the first coupling component, and further reducing the height of the bottom shell, making it easier for users to store it and improving the aesthetics of the product.

[0006] In some embodiments, the top wall of the protruding area is a planar structure. The planar structure allows the heating component in the bottom shell to fit better with the top wall, and the heating component has high heat transfer efficiency and fast heat transfer rate to the bottom wall of the container.

[0007] In some embodiments, the diameter D of the top wall of the protruding area is greater than or equal to the diameter d of the first coupling member. In this way, the size of the protruding area is sufficient to accommodate the first coupling member, which is conducive to installing the first coupling member in the space formed by the protruding area. In addition, since the top surface of the heating component matches the protruding area, the heating component is designed in a flat structure at the top. Therefore, setting the top wall of the protruding area as a flat structure is also conducive to the fixed installation of the first coupling member and the heating component.

[0008] In some embodiments, the protrusion height of the protruding area is greater than or equal to 10 mm and less than or equal to 20 mm. Within this range, on the one hand, it is possible to avoid the problem that the height of the bottom shell is still too high due to the protrusion height being too small, resulting in insufficient axial height of the expanded bottom shell, and the expanded axial space is not enough to accommodate the first coupling member; on the other hand, it is possible to avoid the protrusion height being too large, resulting in processing difficulties.

[0009] In some embodiments, the bottom wall of the container further includes an annular area arranged on the periphery of the protruding area, and the annular area is a plane structure or an arc surface structure. The annular area with a plane structure has a simple structure and is easy to process and produce; the annular area with an arc surface structure has a smoother and more seamless connection with the protruding area.

[0010] In some embodiments, the protruding area further includes a connecting wall connecting the annular area and the top wall of the protruding area, and the connecting wall is a plane structure or a curved surface structure. The connecting wall with a plane structure is simple in structure and easy to process and produce; the connecting wall with a curved surface structure is conducive to increasing the heat conduction area, can reduce the heat per unit area of ​​the connecting wall, and effectively prevent the bottom from being burnt.

[0011] In some embodiments, when the annular region is a planar structure, the angle between the connecting wall and the annular region is greater than or equal to 90°. This arrangement can make it possible to avoid a cleaning dead angle between the connecting wall and the annular region as much as possible, facilitate cleaning, and facilitate cleaning of the container body.

[0012] In some embodiments, when the annular region is a planar structure, the width of the annular region is greater than or equal to 3 mm. This arrangement makes the width of the annular region wide enough to facilitate cleaning and facilitate cleaning of the container body.

[0013] In some embodiments, when the annular region is a concave arc surface structure, the annular region is tangent to the connecting wall, and the radius of the annular region is greater than or equal to 1.5 mm. This arrangement can make it possible to avoid a cleaning dead angle between the connecting wall and the annular region as much as possible, facilitate cleaning, and facilitate cleaning of the container body.

[0014] In some embodiments, the heating assembly includes: a steel plate connected to the bottom of the container body, the steel plate is provided with a boss adapted to the lower surface of the protruding area; a heat-conducting bracket is provided on the lower surface of the steel plate; and a heating element is provided on the lower surface of the heat-conducting bracket. In this arrangement, the boss of the steel plate is located in the cavity formed by the outer surface of the protruding area. Since the boss is adapted to the protruding area, on the one hand, it is beneficial for the heating assembly to transfer heat to the bottom wall of the container. On the other hand, it can also make the axial accommodation height between the bottom shell and the steel plate larger, providing partial accommodation space for the first coupling element, thereby reducing the axial height of the bottom shell occupied by the first coupling element, and then reducing the height of the bottom shell, which is convenient for users to store and improves the aesthetics of the product. Furthermore, a heat-conducting bracket is provided between the steel plate and the heating element, which can improve the heat transfer efficiency between the heating element and the steel plate.

[0015] In some embodiments, the container body is a glass container body, and the liquid heating container further includes: a thermal pad, which is sandwiched between the steel plate and the bottom wall of the container, the thermal pad is in contact with the lower surface of the protruding area, and the lower surface of the thermal pad is in contact with the upper surface of the steel plate. In this arrangement, the container body is a glass container body, that is, the side walls and the bottom wall of the container are both made of glass. The glass material is safe and suitable for holding a variety of solutions. It can be used for making tea, porridge, soup and other food materials, and has good safety performance. In addition, the all-glass container body is more aesthetically pleasing. Furthermore, the provision of the thermal pad can fill the gap between the bottom wall of the container and the upper surface of the steel plate, thereby improving the heat transfer efficiency and uniformity of the heating component to the container body, so that the container body is heated more evenly and heated at a faster rate.

[0016] In some embodiments, the container sidewall is a glass sidewall, the steel plate is sealed to the lower end of the container sidewall, the steel plate forms the container bottom wall, and the protruding area is formed on the steel plate. In this configuration, the steel plate forms the container bottom wall, so that the heating component is in direct contact with the liquid in the container body, and the heating efficiency is higher than that of the container bottom wall made of glass.

[0039] The following will be combined Figures 1 to 8 A liquid heating container provided in an embodiment of the present invention is introduced.

[0040] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, a first aspect of an embodiment of the present invention provides a liquid heating container, comprising: a bottom shell 10, in which a heating component 20 and a first coupling member 110 are arranged; a container body 30, the container body 30 is connected to the bottom shell 10, the container body 30 comprises a container side wall 310 and a container bottom wall 320, the container bottom wall 320 comprises a protruding area 321 protruding toward the inside of the container body 30, and the lower surface of the protruding area 321 and the bottom shell 10 enclose a receiving cavity that can accommodate the heating component 20 and the first coupling member 110.

[0041] The liquid heating container provided in the embodiment of this aspect has a bottom wall 320 that protrudes toward the inside of the container body 30 to form an inwardly convex structure. The heating component 20 and the first coupling member 110 are hidden between the protruding area 321 and the bottom wall of the bottom shell 10. The setting of the protruding area 321 can provide partial accommodation space for the heating component 20 and the first coupling member 110, thereby reducing the axial height of the bottom shell 10 occupied by the heating component 20 and the first coupling member 110, thereby lowering the height of the bottom shell 10, making it easier for users to store them and improving the aesthetics of the product.

[0042] In some embodiments, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, the top wall 322 of the protruding area 321 is a planar structure. The planar structure allows the heating component 20 in the bottom shell 10 to fit better with the top wall 322, and the heat transfer efficiency and speed of the heating component 20 to the bottom wall 320 of the container are high.

[0043] Furthermore, in some embodiments, the liquid heating container also includes a temperature control unit 80, which is disposed on the heating component 20. The top wall 322 of the protruding area 321 is set as a planar structure. The heating component 20 is designed to be flat, which can also increase the contact area between the temperature control unit 80 and the surface of the heating component 20, making the temperature control more sensitive.

[0044] In some embodiments, Figure 1 As shown, the diameter D of the top wall 322 of the protruding area 321 is greater than or equal to the diameter d of the first coupling member 110. In this way, the size of the protruding area 321 is sufficient to accommodate the first coupling member 110, which is conducive to installing the first coupling member 110 in the space formed by the protruding area 321. In addition, since the top surface of the heating component 20 matches the protruding area 321, the heating component 20 is designed in a flat structure at the top. Therefore, setting the top wall 322 of the protruding area 321 as a flat structure is also conducive to the fixed installation of the first coupling member 110 and the heating component 20.

[0045] In some embodiments, the protrusion height of the protrusion area 321 is greater than or equal to 10 mm and less than or equal to 20 mm. Within this range, on the one hand, it is possible to avoid the problem that the height of the bottom shell 10 is still too high due to the protrusion height being too small, and the expanded axial space is not enough to accommodate the first coupling member 110; on the other hand, it is possible to avoid the protrusion height being too large, which causes processing difficulties.

[0046] In some embodiments, Figure 1 As shown, the distance between the lower surface of the top wall 322 of the protruding area 321 and the lower surface of the bottom wall of the bottom shell 10 is a first spacing H1, wherein the first spacing H1 is equal to the sum of the thickness of the thermal pad 60, the thickness of the steel plate 210 and the thermal bracket 220, and the height of the first coupling member 110; the distance between the highest point of the lower surface of the annular area 323 and the lower surface of the lowest position of the heating component 20 is a1, the distance between the lower surface of the lowest position of the heating component 20 and the upper surface of the bottom wall of the bottom shell 10 is a2, and the thickness of the bottom wall of the bottom shell 10 is a3, wherein the protruding height H of the protruding area 321 = H1-a1-a2-a3. It can be understood that the lowest position of the heating component 20 is the bottom wall of the groove 211. Such an arrangement allows the components arranged in the space between the bottom shell 10 and the bottom wall 320 of the container to be densely distributed in the axial height and to occupy as little excess axial space as possible, thereby reducing the height of the bottom shell 10 as much as possible, making it convenient for users to store and improving the aesthetics of the product. In addition, the height of the protruding area 321 is set to have the above-mentioned dimensional relationship with each component, and the height of the protruding area 321 can also be adapted to the size of the component arranged between the bottom shell 10 and the protruding area 321, so that the top wall 322 of the protruding area 321 can better fit the heating component 20.

[0047] It is understandable that the distance a2 between the lower surface of the lowest position of the heating component 20 and the upper surface of the bottom wall of the bottom shell 10 cannot be too small, otherwise the heating component 20 will be too close to the bottom shell 10, causing the bottom shell 10 to be overheated or even melted.

[0048] In some embodiments, Figure 2 , Figure 3 and Figure 4 As shown, the container bottom wall 320 also includes an annular area 323 arranged on the periphery of the protruding area 321, and the annular area 323 is a plane structure or an arc surface structure. The annular area 323 with a plane structure has a simple structure and is easy to process and produce; the annular area 323 with an arc surface structure is more smoothly connected to the protruding area 321. Figure 2 The annular region 323 of the container body 30 is a schematic structural diagram of a planar structure; Figure 3 , Figure 4 It is a structural schematic diagram showing that the annular region 323 of the container body 30 is a circular arc surface structure.

[0049] In some embodiments, Figure 2 As shown, when the annular region 323 is a planar structure, the angle a between the connecting wall 324 and the annular region 323 is greater than or equal to 90°. This arrangement can make it possible to avoid a cleaning dead angle between the connecting wall 324 and the annular region 323 as much as possible, facilitate cleaning, and facilitate cleaning of the container body 30.

[0050] In some embodiments, Figure 2 As shown, when the annular region 323 is a planar structure, the width W of the annular region 323 is greater than or equal to 3 mm. This arrangement makes the width W of the annular region 323 wide enough to facilitate cleaning and facilitate cleaning of the container body 30.

[0051] In some embodiments, Figure 3 and Figure 4 As shown, when the annular region 323 is a concave arc surface structure, the annular region 323 is tangent to the connecting wall 324, and the radius R of the annular region 323 is greater than or equal to 1.5 mm. In this way, there is no cleaning dead corner between the connecting wall 324 and the annular region 323 as much as possible, which is convenient for cleaning and conducive to cleaning of the container body 30.

[0052] In some embodiments, Figure 2 , Figure 3 and Figure 4As shown, the protruding area 321 also includes a connecting wall 324 connecting the annular area 323 and the top wall 322 of the protruding area 321, and the connecting wall 324 is a plane structure or a curved surface structure. The connecting wall 324 with a plane structure has a simple structure and is easy to process and produce; the connecting wall 324 with a curved surface structure is conducive to increasing the heat conduction area, can reduce the heat per unit area of ​​the connecting wall 324, and effectively prevent the bottom from being burnt. Figure 2 , Figure 3 The connecting wall 324 of the container body 30 is a schematic structural diagram of a curved surface structure; Figure 4 It is a schematic structural diagram of the connecting wall 324 of the container body 30 being a planar structure.

[0053] Regarding the specific structure of the heating component 20, in some embodiments, such as Figure 1 , Figure 6 and Figure 8 As shown, the heating assembly 20 includes: a steel plate 210, connected to the bottom of the container body 30, and provided with a boss matched with the lower surface of the protruding area 321 on the steel plate 210; a heat-conducting bracket 220, arranged on the lower surface of the steel plate 210; and a heating element 230, arranged on the lower surface of the heat-conducting bracket 220. In this way, the boss of the steel plate 210 is located in the cavity enclosed by the outer surface of the protruding area 321. Since the boss is matched with the protruding area 321, on the one hand, it is beneficial for the heating assembly 20 to transfer heat to the container bottom wall 320, and on the other hand, it can also make the axial accommodation height between the bottom shell 10 and the steel plate 210 larger, providing a partial accommodation space for the first coupling element 110, thereby reducing the axial height of the bottom shell 10 occupied by the first coupling element 110, and further reducing the height of the bottom shell 10, which is convenient for users to store and improves the aesthetics of the product. Furthermore, a heat-conducting bracket 220 is provided between the steel plate 210 and the heating element 230 , which can improve the heat transfer efficiency between the heating element 230 and the steel plate 210 .

[0054] Furthermore, in some embodiments, the heat-conducting bracket 220 is an aluminum plate, which has good thermal conductivity and can transfer the heat of the heating element 230 to the aluminum plate more quickly, and then to the steel plate 210 .

[0055] Furthermore, in some embodiments, the heating element 230 is a heating tube. Specifically, the heating tube is welded to the aluminum plate, and the aluminum plate is welded to the steel plate 210. The welding connection is resistant to high temperatures and is not easy to loosen.

[0056] In the first embodiment of the present application, Figures 1 to 6As shown, the container body 30 is a glass container body 30, and the liquid heating container further includes: a heat conductive pad 60, which is sandwiched between the steel plate 210 and the container bottom wall 320, and the heat conductive pad 60 is in contact with the lower surface of the protruding area 321, and the lower surface of the heat conductive pad 60 is in contact with the upper surface of the steel plate 210. In this way, the container body 30 is a glass container body 30, that is, the container side wall 310 and the container bottom wall 320 are both made of glass. The glass material is safe and suitable for holding a variety of solutions, and can be used for a variety of ingredients such as tea, porridge, and soup, with good safety performance. In addition, the all-glass container body 30 is also more aesthetically pleasing. Furthermore, the setting of the heat conductive pad 60 can fill the gap between the container bottom wall 320 and the upper surface of the steel plate 210, which improves the heat transfer efficiency and heat transfer uniformity of the heating component 20 to the container body 30, so that the container body 30 is heated more evenly and the heating rate is faster.

[0057] In some embodiments, the material of the container body 30 is preferably high borosilicate glass. High borosilicate glass has good high temperature resistance and high mechanical strength and hardness. It can be made into thin-walled but durable glass products and is suitable for products that need to withstand a certain amount of pressure or impact.

[0058] Further, as an example, optionally, the thermal pad 60 can be made of thermally conductive silicone or thermally conductive graphite. Thermally conductive silicone has excellent thermal conductivity and insulation properties, and thermally conductive silicone has a certain flexibility, can adapt to irregular surfaces, and has good adhesion to most metal and non-metal materials; thermally conductive graphite is a material with excellent thermal conductivity, and has the advantages of high thermal conductivity, light weight, good thermal stability and environmental protection.

[0059] In some embodiments, as an example, optionally, Figure 1 , Figure 6 and Figure 7 As shown, a circle of grooves 211 are provided on the steel plate 210 at a position opposite to the container side wall 310, which are used to connect with the container side wall 310. Specifically, glue or other adhesives 240 are placed in the grooves 211, and the container side wall 310 is inserted into the grooves 211 and bonded to the grooves 211 by glue or other adhesives 240, thereby realizing the connection between the container side wall 310 and the steel plate 210.

[0060] Furthermore, in some embodiments, Figure 1 , Figure 6 and Figure 7As shown, the lower end of the container side wall 310 shrinks inward to form a closing portion 311, and the closing portion 311 is inserted into the groove 211 and bonded to the groove 211 by glue or other adhesives 240. Specifically, since the closing portion 311 is formed by the lower end of the container side wall 310 shrinking inward, the outer diameter of the closing portion 311 is smaller than the outer diameter of the container side wall 310, forming a stepped structure with a larger upper portion and a smaller lower portion. The closing portion 311 with a smaller diameter is matched with the groove 211, so that the outer peripheral side wall of the bottom shell 10 can be roughly flush with the container side wall 310, thereby improving the aesthetics.

[0061] Furthermore, in some embodiments, Figure 1 , Figure 6 and Figure 7 As shown, the closing portion 311 also includes a stopper portion extending generally in a horizontal direction toward the interior of the container body 30 , and the stopper portion abuts against the upper surface of the bottom shell 10 to achieve axial positioning of the bottom shell 10 and the container body 30 .

[0062] In some embodiments, the container body 30 is made of glass, and the wall thickness of the container bottom wall 320 is smaller than the wall thickness of the container side wall 310 .

[0063] In these embodiments, the container side walls 310 and the container bottom wall 320 are both made of glass, and the wall thickness of the container bottom wall 320 is less than that of the container side walls 310. By setting the container bottom wall 320 thinner than the container side walls 310, the thermal conductivity of the container bottom wall 320 is better, and heat can be introduced into the container body 30 in time, thereby accelerating the heating of the food and shortening the cooking time. In addition, the container side walls 310 are set to be thicker than the container bottom wall 320, while ensuring the heating effect, the structural strength of the container body 30 is enhanced, thereby reducing the risk of the container body 30 being broken by collision, and improving the reliability and safety of the container body 30.

[0064] In some embodiments, the thickness of the container sidewall 310 is greater than 3 mm and less than or equal to 5 mm. Within this range, on the one hand, the problem that the container sidewall 310 is too thin, resulting in a low structural strength of the container sidewall 310 and easy breakage during use is avoided; on the other hand, the problem that the container sidewall 310 is too thick, resulting in an increase in the weight of the container body 30, inconvenience for users, unnecessary increase in material input, and waste of materials is avoided.

[0065] 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 too thin and prone to rupture during use is avoided, and on the other hand, the problem of the container bottom wall 320 being too thick and resulting in poor thermal conductivity and slow heating efficiency is avoided. In addition, a thicker container bottom wall 320 will also increase the weight of the container body 30, which is inconvenient for users to use, increases unnecessary material input, and causes material waste.

[0066] In some embodiments, when 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. In this way, the thickness of the container side wall 310 is different from that of the container bottom wall 320 through the tube glass molding process, and has the advantages of high transparency, chemical stability, high temperature and high pressure resistance, high mechanical strength, etc.

[0067] In some embodiments, Figure 5 and Figure 6 As shown, the liquid heating container also includes a base 90, on which is disposed a second coupling member 910 that cooperates with the first coupling member 110. When the bottom shell 10 is placed on the base 90, the first coupling member 110 and the second coupling member 910 are plugged into each other to enable electrical components such as the heating member 230 in the bottom shell 10 to be powered on.

[0068] In some embodiments, Figure 1 , Figure 5 and Figure 7 As shown, the liquid heating container further includes: a handle 50, which is connected to the container body 30, and the upper end of the handle 50 is clamped on the top of the container side wall 310, or a fixing ring is provided on the upper end of the container body 30, and the upper end of the handle 50 is connected to the fixing ring by a screw, and the lower end of the handle 50 is connected to the bottom shell 10. In this way, the container body 30 can be taken by the handle 50, making it more convenient to take and put the container body 30.
