Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to an electric kettle and an automatic liquid dispensing device. Background Technology

[0002] Automatic liquid dispensing devices equipped with transparent glass containers are favored by consumers due to their aesthetic appeal, hygiene, and ease of use. However, these devices have the following drawbacks: The glass containers typically require through-holes for the detection elements to enter and monitor temperature / liquid level. This not only increases manufacturing complexity but also potentially compromises the structural strength of the glass container, making it prone to cracking during heating. Furthermore, the bottom of the glass container usually has a heating element. When this element is in direct or tight contact with the bottom of the glass container, the significant difference in their coefficients of thermal expansion and uneven heat transfer at the contact surface can easily lead to localized overheating or increased stress, resulting in cracking. Utility Model Content

[0003] To address the above problems, this utility model provides an electric kettle and an automatic liquid dispensing device, which can effectively prevent glass containers from cracking during the heating process.

[0004] This utility model provides an electric kettle, comprising:

[0005] The glass container is a one-piece molded structure. The glass container has a bottom surface and a side wall. The side wall has liquid passage holes that are spaced apart from the bottom surface.

[0006] The heat-conducting plate has a disc-shaped surface and a peripheral protrusion. The disc-shaped surface is separated from and opposite the bottom surface of the glass container. The peripheral protrusion is located on the outer periphery of the disc-shaped surface and protrudes towards the bottom surface of the glass container. The bottom surface of the glass container, the disc-shaped surface, and the peripheral protrusion enclose and form a filling space.

[0007] A flexible thermally conductive silicone rubber layer is filled in the filling space and bonded to the disc-shaped surface and the bottom surface of the glass container.

[0008] The heating element is fixed to the side of the heat-conducting plate away from the bottom of the glass container;

[0009] A liquid coupling is located on the side of the heating assembly furthest from the glass container and is spaced apart from the heating assembly; and

[0010] The piping assembly has its first end passing through a liquid inlet and communicating with the interior of the glass container, and its second end connected to a liquid coupling.

[0011] According to the above technical solution, the number of openings in the glass container is reduced, which can effectively improve the structural strength and reduce the risk of the glass container cracking. At the same time, a heat-conducting plate is set between the heating component and the glass container. The heat of the heating component is transferred to the glass container through the flexible thermally conductive silicone rubber layer filled in the heat-conducting plate, which is conducive to improving the heat conduction effect and heating uniformity. Meanwhile, the flexible thermally conductive silicone rubber layer can buffer the expansion of the heat-conducting plate to a certain extent and prevent the glass container from cracking.

[0012] Optionally, it also includes a sealing ring having an inner annular surface and an outer annular surface. The sealing ring is installed between the pipeline assembly and the wall of the fluid passage, with the inner annular surface abutting against the circumferential surface of the pipeline assembly and the outer annular surface abutting against the wall of the fluid passage. The outer diameter of the first end and / or the second end of the sealing ring in the axial direction is larger than the outer diameter of the portion of the sealing ring located inside the fluid passage; or it may further include:

[0013] The sealing ring has an inner ring surface and an outer ring surface. The sealing ring is installed between the pipeline assembly and the wall of the liquid passage hole. The inner ring surface abuts against the circumferential surface of the pipeline assembly, and the outer ring surface abuts against the wall of the liquid passage hole. The outer diameter of the first end and / or the second end of the sealing ring in the axial direction is greater than the outer diameter of the portion of the sealing ring located inside the liquid passage hole.

[0014] A baffle protrudes from the circumferential surface of the piping assembly and abuts against the end of the sealing ring facing the interior space of the glass container.

[0015] The above technical solution improves the sealing performance between the pipeline assembly and the liquid passage, reducing the chance of leakage.

[0016] Optionally, the heating element is a heating tube with wires connected to both ends. The electric kettle also includes: a power socket surrounding the liquid coupling; and a heat insulation plate disposed between the heating element and the power socket. The heat insulation plate has a central portion and an outer peripheral bend. The outer peripheral bend extends from the outer periphery of the central portion of the heat insulation plate towards the glass container. The central portion of the heat insulation plate has a wire hole through which the power supply wire passes, and the outer peripheral bend has multiple heat dissipation holes evenly distributed in the circumferential direction.

[0017] According to the above technical solution, the heat insulation plate can effectively prevent the heat generated by the heating element from being transferred downwards to the power socket and the liquid coupling, thus avoiding high temperatures affecting the service life of the power socket and the liquid coupling. Furthermore, the heating element's wires must pass through the wire hole before connecting to the power socket, effectively ensuring the separation between the heating element and the power socket; simultaneously, the heat dissipation holes in the heat insulation plate provide a heat dissipation channel, preventing heat from accumulating at the bottom of the glass container and causing the bottom temperature of the glass container to become excessively high.

[0018] Optionally, it also includes: a kettle base, the kettle base being configured as a bowl shape, the bottom center of the kettle base being recessed and forming an opening for installing the liquid coupling, and the side wall of the kettle base having kettle base heat dissipation holes corresponding to the heat dissipation holes of the heat insulation plate.

[0019] According to the above technical solution, the heat dissipation holes on the base of the kettle can further carry away the heat dissipation holes of the heat insulation plate from the base of the kettle, effectively ensuring the heat dissipation effect.

[0020] Optionally, it also includes: a sealing ring, the top end face of which is formed to abut against the outer edge of the bottom surface of the glass container, the bottom end face of which has an outer convex ring and an inner convex ring, the outer periphery of the pot body base is inserted between the outer convex ring and the inner convex ring, and the outer periphery of the heat insulation plate is bent against the inner side of the inner convex ring.

[0021] According to the above technical solution, the sealing ring can make the structure more compact and provide reliable sealing.

[0022] Optionally, it also includes a temperature / level detection element, including a detection head, which is attached to the outer surface of the sidewall of the glass container, and the attachment position of the detection head is adjacent to the setting position of the liquid passage hole.

[0023] According to the above technical solution, the detection head of the temperature / liquid level detection element is attached to the outer surface of the side wall for septum detection, which can completely avoid the need to make additional holes for the detection element on the glass container; at the same time, the detection head is adjacent to the liquid passage hole, which makes it easy to cover and shield it with the handle.

[0024] Optionally, it also includes: a handle that covers and shields the temperature / level sensing element, the liquid passage, and at least a portion of the piping assembly.

[0025] According to the above technical solution, it can protect relatively fragile detection elements and pipeline components, while making the appearance simpler and more aesthetically pleasing.

[0026] Optionally, it also includes: a circuit board, installed inside the handle, a temperature / level sensing element connected to the circuit board, and the circuit board also communicating with the power socket via a signal line.

[0027] According to the above technical solution, the internal space of the handle can be fully utilized, avoiding the need for additional circuit boards and making the structure more compact. By setting up a circuit board, the output terminal of the temperature / liquid level detection element is connected to the power socket via the circuit board, reducing the number of pins on the connection terminal of the temperature / liquid level detection element and simplifying the circuit layout. Furthermore, placing the circuit board on the handle, maintaining an appropriate distance from the heating component, helps optimize the working environment of the circuit board and improves its lifespan. Simultaneously, the circuit board can control the current input from the power socket to the heating component, thereby controlling the operation of the heating component accordingly.

[0028] Optionally, the power socket is fixed to the heat insulation plate using a positioning mounting bracket, and heat insulation cotton is provided between the positioning mounting bracket and the heat insulation plate.

[0029] According to the above technical solution, the heat insulation effect can be further guaranteed, thereby further ensuring the service life of the plug-in socket and the liquid coupling located below the positioning mounting part.

[0030] Optionally, the end of the tubing assembly located inside the glass container is coaxially arranged with the liquid inlet, and the vertical distance between the center of the liquid inlet and the bottom of the glass container is not less than 5 mm; or the end of the tubing assembly located inside the glass container extends towards the bottom of the glass container, and the vertical distance between the center of the liquid inlet and the bottom of the glass container is not less than 5 mm.

[0031] According to this technical solution, by limiting the aforementioned vertical distance and extending the pipeline assembly towards the bottom of the glass container, the risk of glass container breakage caused by drilling at too low a position can be reduced.

Detailed Implementation

[0048] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0049] refer to Figure 1 and Figure 2 An electric kettle 100 according to this embodiment includes:

[0050] The glass container 10 is a one-piece molded structure, having a bottom surface and side walls. The side walls have liquid passage holes 11 spaced apart from the bottom surface. Specifically, the one-piece molded structure of the glass container 10 eliminates seams, reducing hygiene dead zones and the probability of leakage. Since there are no seams, adhesives and other organic materials are not used, thus better ensuring food safety. The liquid passage holes 11 are located on the side walls of the glass container 10 to connect the interior and exterior, and are separated from the heating element 30, reducing the impact of the heating element 30 at high temperatures on the structural strength of the liquid passage holes 11. In this embodiment, the heating component 30 is located at the bottom of the glass container 10. The vertical distance between the center of the liquid passage hole 11 and the bottom surface of the glass container is not less than 5mm, and preferably 5mm to 50mm. The smaller the vertical distance, the more difficult the drilling process becomes, which can easily damage the glass container 10. If the vertical distance is too large, that is, the opening position of the liquid passage hole 11 is higher, the water inlet or outlet position is higher, and the required pipeline component 50 is longer, which increases the difficulty of hiding the pipeline component 50. Moreover, when water is drawn from the liquid passage hole 11, it is easy to cause a lot of residual liquid in the glass container 10 that cannot be discharged. The shape of the liquid passage hole 11 can be, but is not limited to, circular or square. Its shape, size, opening position and other parameters can be selected according to actual needs, and are not limited here. Preferably, the end of the tubing assembly 50 located inside the glass container 10 can be coaxially arranged with the liquid inlet 11, or extend towards the bottom of the glass container 10, so that the end of the tubing assembly 50 located inside the glass container 10 is not at the same height as the liquid inlet 11, thereby moving the drilling position upward and reducing the risk of damage to the glass container due to drilling.

[0051] refer to Figure 3 The heat-conducting plate 20 has a disc-shaped surface 21 and a peripheral protrusion 22. The disc-shaped surface 21 is spaced apart from and opposite the bottom surface of the glass container. The peripheral protrusion 22 is located on the outer periphery of the disc-shaped surface 21 and protrudes towards the bottom surface of the glass container. The bottom surface of the glass container, the disc-shaped surface 21, and the peripheral protrusion 22 enclose a filling space. Specifically, the heat-conducting plate 20 has a disc-shaped surface 21 facing the bottom surface of the glass container and spaced apart from it. The disc-shaped surface 21 helps to increase the contact area between the heat-conducting plate 20 and the bottom surface of the glass container. The peripheral protrusion 22 is provided on the outer periphery of the disc-shaped surface 21 and protrudes towards the bottom surface of the glass container, so that the bottom surface of the glass container, the disc-shaped surface 21, and the peripheral protrusion 22 enclose a filling space, which is filled with a flexible thermally conductive silicone rubber layer.

[0052] refer to Figure 3In this embodiment, a plurality of through grooves 23 are also provided on the heat-conducting plate 20. The through grooves 23 extend through the upper and lower end faces of the heat-conducting plate 20 along the axial direction of the heat-conducting plate 20. The heating component 30 at least partially covers the through grooves 23, which can buffer the thermal expansion of the heat-conducting plate 20 caused by the heating component 30 heating the heat-conducting plate 20, and further prevent the glass container 10 from being stretched and breaking. At the same time, the plurality of through grooves 23 are distributed along the circumferential direction of the disc-shaped surface 21. The through grooves 23 extend from the middle of the heat-conducting plate 20 to the outer edge of the heat-conducting plate 20, which can fully buffer the thermal expansion of the heat-conducting plate 20, further preventing the glass container 10 from shattering. The through grooves 23 also help to expel air bubbles in the flexible thermally conductive silicone rubber layer and improve thermal conductivity. In some embodiments, in order to buffer the above-mentioned thermal expansion, a plurality of non-through grooves may also be provided on the heat-conducting plate 20.

[0053] A flexible thermally conductive silicone rubber layer fills the filling space and is bonded and fixed to the disc-shaped surface 21 and the bottom surface of the glass container. Specifically, a heating component 30 is provided on the side of the heat-conducting disc 20 away from the glass container 10. When the heat-conducting disc 20 is heated by the heating component 30, the heat-conducting disc 20 can transfer heat to the flexible thermally conductive silicone rubber layer, and then the flexible thermally conductive silicone rubber layer can transfer heat to the glass container 10. When the heat-conducting disc 20 is heated, it will undergo thermal expansion, and the flexible thermally conductive silicone rubber layer can buffer the expansion of the heat-conducting disc 20 to a certain extent, preventing the glass container 10 from cracking. The flexible thermally conductive silicone rubber layer connects the heat-conducting disc 20 to the bottom surface of the glass container, so that the heat-conducting disc 20 is in close contact with the bottom of the glass container 10, increasing the heat conduction area, which is beneficial to improving the heat conduction effect and the uniformity of heating. Moreover, because a high-temperature curing silicone rubber material is used, it will not volatilize like the grease in thermally conductive silicone grease, which would lead to a decrease in thermal conductivity. Its performance is stable under long-term high-temperature operation.

[0054] Furthermore, the flexible thermally conductive silicone rubber layer flows into the filling space and, after high-temperature curing, bonds the bottom surface of the glass container to the disc-shaped surface 21. This method achieves the fixation of the flexible thermally conductive silicone rubber layer without the need for additional adhesives or components, simplifying the process. Simultaneously, the peripheral protrusions 22 prevent the flow of the flexible thermally conductive silicone rubber layer within the filling space from overflowing and facilitate the filling of the thermally conductive silicone layer. Moreover, the peripheral protrusions 22 ensure that the filling space has a certain depth, guaranteeing a certain thickness for the flexible thermally conductive silicone rubber layer, thereby improving the flexibility of the thermally conductive silicone and ensuring better cushioning performance during thermal expansion, preventing the glass container 10 from shattering.

[0055] refer to Figure 4The heating component 30 is fixed to the side of the heat-conducting plate 20 away from the bottom surface of the glass container and is used to heat the glass container 10. The heating component 30 is located below the bottom surface of the glass container 10 and is in contact with the glass container 10. It is electrically connected to the relevant heating circuit. After the power is turned on, current flows through the heating component 30, which realizes the conversion from electrical energy to heat energy. The generated heat energy can be transferred to the bottom surface of the glass container 10 through heat conduction and finally to the liquid inside the glass container 10, so that the temperature of the liquid continuously rises. Since the heating component 30 is located below the bottom surface of the glass container 10, it is far away from the liquid passage hole 11 opened on the side of the glass container 10. This liquid passage hole 11 is the weakest area of ​​the integrally formed glass container 10 and is more likely to crack under thermal expansion and contraction than other parts. By keeping it away from the heating component 30, direct contact with the high-temperature heating component 30 is avoided, which can reduce the occurrence of this problem and thus better ensure the safety of this electric kettle 100.

[0056] The liquid coupling 40 is located on the side of the heating assembly 30 away from the glass container 10 and is separated from the heating assembly 30. Specifically, the liquid coupling 40 is separated from the heating assembly 30. This liquid coupling 40 can realize liquid inlet operation, liquid outlet operation, or single liquid inlet or outlet operation of the glass container 10. It can be set at a certain distance below the heating assembly 30 to avoid being affected by the high temperature of the heating assembly 30. Therefore, the liquid coupling 40 itself will not overheat and soften due to high temperature, thus affecting its normal function, nor will it release gas due to overheating. The separation between the two can be achieved by a certain type of heat insulation component. The separation distance can be determined according to actual needs and is not limited here.

[0057] The piping assembly 50 has its first end passing through the liquid passage 11 and communicating with the interior of the glass container 10, and its second end being connected to the liquid coupling 40. Specifically, the first end of the pipe assembly 50 passes through the liquid passage 11 and communicates with the internal space of the glass container 10, and the second end is connected to the liquid coupling 40 to sequentially connect the internal space of the glass container 10, the pipe assembly 50, and the liquid coupling 40. This pipe assembly 50 has a certain length, and its function is to allow the liquid inside the glass container 10 to flow outward while maintaining a certain distance between the liquid coupling 40 and the liquid passage. The liquid coupling 40 can be connected to the relevant liquid dispensing mechanism of the automatic liquid dispensing device 200. In this case, when the user presses the relevant liquid dispensing button of the automatic liquid dispensing mechanism, the liquid coupling 40 can connect the entire liquid pipeline. Under the pumping action, the liquid in the internal space of the glass container 10 can sequentially pass through the pipe assembly 50, the liquid coupling 40, and the relevant liquid dispensing mechanism, and then flow out from the dispensing nozzle. The liquid mentioned here includes, but is not limited to, water and milk, and can also be beverages such as coffee and juice. It is not limited here. It can be seen that this solution can achieve automatic liquid dispensing of the entire glass pot while ensuring hygiene and safety.

[0058] In this embodiment, the piping assembly 50 may include a liquid-passing connector 51 and a connecting pipe 52 that are interconnected. The liquid-passing connector 51 passes through the liquid-passing hole 11 and extends into the internal space of the glass container 10. The connecting pipe 52 is located on the outside of the glass container 10. This connecting pipe 52 can be made of a relatively soft material, which makes it easy to bend, while also requiring it to have a certain strength to avoid collapsing under natural conditions and affecting the liquid flow. This makes it easier to freely arrange on the outside of the side and below the bottom of the glass container 10.

[0059] The liquid in the glass container 10 passes through the liquid inlet 51 and the connecting pipe 52 in sequence to reach the liquid coupler 40. The length of the connecting pipe 52 depends on the distance between the end of the liquid inlet 51 located outside the glass container 10 and the liquid inlet end of the liquid coupler 40. The internal diameter can be determined according to the actual required liquid discharge speed. When a faster liquid discharge speed is required, the internal diameter can be set to be larger, and vice versa.

[0060] In other cases, the liquid coupling 40 can also function as a liquid inlet, in which case the liquid flow direction is reversed; this will not be elaborated further. It should also be noted that the liquid connector 51 can be made of inorganic materials, such as stainless steel, which will not rust and contaminate the liquid after prolonged immersion. Alternatively, it can be made of organic materials that do not release harmful substances; the choice depends on the specific needs. The connecting pipe 52 can be made of silicone, which is food-grade safe and poses no health risk to users. Furthermore, this silicone connecting pipe 52 ensures a sealed connection with the liquid connector 51, preventing leakage at the joint. Of course, other materials can also be used to manufacture this piping assembly 50, and no restrictions are imposed here.

[0061] In this embodiment, a sealing ring 12 is provided between the pipeline assembly 50 and the wall of the liquid inlet 11. This sealing ring 12 has an inner ring surface and an outer ring surface. The sealing ring 12 is installed between the pipeline assembly 50 and the wall of the liquid inlet 11. The inner ring surface abuts against the circumferential surface of the pipeline assembly 50, which ensures a better sealing effect and better prevents leakage from this position. Moreover, the outer ring surface abuts against the wall of the liquid inlet 11, further improving the sealing effect and preventing leakage from this position. It can be seen that using this sealing ring 12 can improve the sealing effect of the most leak-prone part of this all-glass kettle, thereby further enhancing the safety of the kettle body. To further enhance the sealing effect, during installation, the sealing ring 12 can be first fitted onto the outer periphery of the liquid-passing connector 51, and then the liquid-passing connector 51 can be inserted into the liquid-passing hole 11, so that the sealing ring 12 is located between the pipe assembly 50 and the hole wall of the liquid-passing hole 11. The inner and outer annular surfaces of the sealing ring 12 abut against the circumferential surface of the pipe assembly 50 and the hole wall of the liquid-passing hole 11, respectively. The specific abutmentation method is not limited; for example, a deformable sealing ring 12 can be selected, with a radial thickness slightly larger than the distance between the pipe assembly 50 and the hole wall of the liquid-passing hole 11. After the sealing ring 12 is inserted into this space, an interference fit is formed, making it less likely to fall off after tightening, resulting in a better sealing effect. Preferably, the outer diameter of the first end and / or the second end of the sealing ring 12 in the axial direction is larger than the outer diameter of the portion of the sealing ring 12 located inside the liquid-passing hole 11 to ensure a good sealing effect at the liquid-passing hole. In this embodiment, the outer diameter of the end of the sealing ring 12 located inside the glass container is larger than the outer diameter of other parts of the sealing ring 12.

[0062] Furthermore, refer to Figure 11The sealing ring 12 protrudes from the inner wall of the glass container 10 on the side facing the internal space of the glass container 10. That is, the sealing ring 12 extends a certain distance into the internal space of the glass container 10. The electric kettle also includes a baffle 17, which is located inside the glass container 10 and is fitted onto the outside of the pipeline assembly 50 (i.e., the outer diameter of the baffle 17 is larger than the diameter of the liquid passage 11, and the baffle 17 protrudes from the circumferential surface of the pipeline assembly 50). This baffle 17 and the pipeline assembly 50 can be integrated (e.g., the pipeline assembly partially forms a structure with an outer diameter larger than the inner diameter of the liquid passage). (Simplified device structure) or separate components, preferably, the baffle 17 is integrally formed into the pipeline assembly 50, and the baffle 17 and the sealing ring 12 are pressed against the side facing the internal space of the glass container 10, so that the baffle 17 can press against this side of the sealing ring 12 to better seal this part of the liquid passage 11; and / or the side of the sealing ring 12 away from the internal space of the glass container 10 protrudes from the outer wall of the glass container 10, that is, the sealing ring 12 can extend a certain distance outside the glass container 10, so that a certain degree of sealing can be formed at this part after fastening. The compression of the seal can create a more effective seal at this location. One end of the pipe assembly 50 extending out of the glass container 10 has an external thread (not shown), and a nut 18 is connected to this thread. The nut 18 abuts against the side of the sealing ring 12 facing away from the interior space of the glass container 10. When the nut 18 is tightened to the pipe assembly 50, the pipe assembly 50 drives the baffle 17 fitted on it to continuously press the side of the sealing ring 12 facing away from the interior space of the glass container 10. In some cases, the baffle 17 can press the sealing ring 12 so tightly that it is almost invisible from the outside, achieving a greater degree of tightness and sealing at this location. The nut 18 can also continuously press the side of the sealing ring 12 facing away from the interior space of the glass container 10. In some cases, the side of the sealing ring 12 facing away from the interior space of the glass container 10 can also be pressed by the nut 18 so tightly that it is invisible from the outside, similarly achieving a greater degree of tightness and sealing at this location. Of course, in other cases, a portion of both sides of the sealing ring 12 can remain visible from the outside; this can be selected according to actual needs.

[0063] In this embodiment, a filter screen can be fixed at the first end of the pipeline assembly 50, so that the liquid can be filtered before it reaches the first end of the pipeline assembly 50, preventing some impurities in the liquid from entering the pipeline assembly 50 and further improving the hygiene of the liquid.

[0064] The electric kettle 100 also includes a power socket 60, which is arranged around the liquid coupling 40; and a heat insulation plate 70, which is disposed between the heating element 30 and the power socket 60. Specifically, the heating element 30 is placed inside the heat insulation plate 70. The heat insulation plate 70 can thermally isolate the heating element 30 from the liquid coupling 40 and the power socket 60, thereby preventing excessive temperature from affecting the service life of the power socket 60 and the liquid coupling 40.

[0065] Heating component 30 is a heating element, and wires 31 are connected to both ends of the heating element. (See reference) Figure 5 The heat insulation plate 70 has a central portion and an outer peripheral bend. The outer peripheral bend extends from the outer periphery of the central portion towards the glass container 10. The central portion has a wire hole 71 through which the power supply line 31 passes, and the outer peripheral bend has multiple heat dissipation holes 72 evenly distributed in the circumferential direction. Specifically, the wire 31 of the heating component 30 can pass through the wire hole 71 and be electrically connected to the plug-in socket 60 outside the heat insulation plate 70, so that the heating component 30 can be disposed inside the heat insulation plate 70 and spaced apart from the bottom of the heat insulation plate 70. The heat dissipation holes 72 on the outer peripheral bend allow the heat generated by the heating component 30 to dissipate, preventing high temperatures from affecting the service life of the plug-in socket 60 and the liquid coupling 40.

[0066] refer to Figure 2 , Figure 6 The electric kettle 100 also includes a positioning mounting piece 80. The plug-in base 60 is fixed to the heat insulation plate 70 using the positioning mounting piece 80, and heat insulation cotton is provided between the positioning mounting piece 80 and the heat insulation plate 70. Specifically, the plug-in base 60 is fixed to the heat insulation plate 70 using the positioning mounting piece 80. The liquid coupling 40 and the plug-in base 60 surrounding the liquid coupling 40 are respectively installed in the positioning mounting piece 80 and located below the heat insulation plate 70. By providing heat insulation cotton between the positioning mounting piece 80 and the heat insulation plate 70, the heat insulation effect can be further improved.

[0067] refer to Figure 5 In this embodiment, the central part of the heat insulation plate is also provided with a first mounting hole 73 for mounting and fixing the heat insulation plate 70 to the heating assembly 30 below, and a second mounting hole 74 for mounting and fixing with the positioning mounting member 80.

[0068] refer to Figure 4 The heat-conducting plate 20 is provided with a heating component 30 on one side, and a first mounting post 24 and a second mounting post 25 are arranged thereon. The first mounting post 24 matches the first mounting hole 73. The bottom of the first mounting post 24 is provided with a connection hole. After aligning the connection hole with the first mounting hole 73, the heat insulation plate 70 is fixedly installed below the heat-conducting plate 20 by screwing in the screw.

[0069] In this embodiment, after the heat insulation plate 70 is installed via the first mounting post 24 and the first mounting hole 73, the first mounting post 24 can also provide support and fixation, so that the heat-conducting plate 20 with the heating component 30 is stably placed in the internal space of the heat insulation plate 70 and is spaced above the bottom surface of the heat insulation plate 70. This provides sufficient internal space so that the heat from the heating component 30 can be dissipated through the heat dissipation holes 72 on the outer circumferential bending portion of the heat insulation plate. The heat dissipation holes 72 of the heat insulation plate can be elongated, circular, elliptical, or other shapes. The shape, number, and size are not limited here, as long as they can quickly dissipate the heat from the internal space of the heat insulation plate 70.

[0070] The second mounting post 25 has a connecting hole at its bottom, and its length is longer than that of the first mounting post 24. After the heat insulation plate 70 is installed and fixed by the first mounting post 24 and the first mounting hole 73, the second mounting post 25 will be inserted into the second mounting hole 74 and exposed at the bottom of the heat insulation plate 70. (Reference) Figure 6 The positioning mounting part 80 has a fixing part 81 on its outer periphery. The fixing part 81 has a hole. By aligning the fixing part 81 with the hole of the second mounting post 25 and screwing in the screw, the positioning mounting part 80 can be fixedly installed below the heat insulation plate 70.

[0071] Furthermore, one of the second mounting posts 25 is disposed between the two ends of the wires 31 of the heating assembly 30. The second mounting post 25 and the wires 31 pass through the wire hole 71 together, and the second mounting post 25 is sequentially connected to the positioning mounting member 80 and the plug-in upper seat 60. In this embodiment, the positioning mounting member 80 is also provided with a plug-in upper seat connection hole 82, and the plug-in upper seat 60 is provided with a corresponding mounting part (not shown in the figure) corresponding to the plug-in upper seat connection hole 82. After alignment, screwing in the screws can further stabilize the positioning mounting member 80 above the plug-in upper seat 60.

[0072] In this embodiment, the combined connection of the above-described structures makes the overall structure more compact. Furthermore, three of each of the first and second mounting posts 24 are arranged in a triangular pattern, effectively ensuring the stability of the heat-conducting plate 20 after installation and the stability of the positioning mounting component 80. The number and arrangement of the first mounting post 24, second mounting post 25, first mounting hole 73, second mounting hole 74, plug-in connector hole 82, and fixing part 81 can be set according to actual usage requirements, as long as it satisfies the stable installation of each component; no specific limitations are made here.

[0073] refer to Figure 7The electric kettle 100 also includes a kettle base 90, which is bowl-shaped. The bottom center of the kettle base 90 is recessed, forming an opening 91 for mounting the liquid coupling 40. The side wall of the kettle base 90 has kettle base heat dissipation holes 92 corresponding to the heat dissipation holes 72 of the heat insulation plate. Specifically, the kettle base 90 is arranged around the outside of the heat insulation plate 70. By aligning the kettle base heat dissipation holes 92 with the heat insulation plate heat dissipation holes 72, the heat dissipated from the heat insulation plate heat dissipation holes 72 can be dissipated to the outside through the kettle base heat dissipation holes 92, further improving the heat dissipation effect. The number and arrangement of the kettle base heat dissipation holes 92 can be adjusted according to actual heat dissipation needs, as long as a good heat dissipation effect is achieved; no specific limitation is made here. Furthermore, the kettle base 90 is made of plastic, which effectively prevents high temperatures from damaging the structure of the kettle base 90.

[0074] refer to Figure 7 and Figure 8 In this embodiment, the opening 91 is provided with a power socket mounting hole 93 around its periphery, and the power socket 60 is provided with a mounting member 61 on its outer periphery. The connection between the kettle body base 90 and the power socket 60 can be realized through the power socket mounting hole 93 and the mounting member 61, and the power socket 60 and the liquid coupling 40 inside the power socket 60 are respectively located at the opening 91.

[0075] refer to Figure 9 The electric kettle 100 also includes a sealing ring 110. The top end face of the sealing ring 110 is configured as an arc surface 111 that abuts against the outer edge of the bottom surface of the glass container. The bottom end face of the sealing ring 110 has an outer convex ring 112 and an inner convex ring 113. (Reference) Figure 2 The outer periphery of the kettle base 90 is inserted between the outer convex ring 112 and the inner convex ring 113, and the outer circumferential bent portion of the heat insulation plate 70 abuts against the inner side of the inner convex ring 113. Specifically, the sealing ring 110 enables a more compact structure and ensures a sealing effect. At the same time, the bottom end of the arc surface 111 is connected to the inner wall surface 114 of the sealing ring 110, which corresponds to the outer peripheral side surface of the heat conduction plate 20, so as to further stabilize the position of the heat conduction plate 20.

[0076] refer to Figure 10The electric kettle 100 also includes a temperature / level detection element, including a detection head 13. The detection head 13 is attached to the outer surface of the side wall of the glass container, and the attachment position of the detection head 13 is adjacent to the location of the liquid passage hole 11. Specifically, the detection head 13 may include a detection head 13 for detecting water temperature and water level. The detection head 13 is attached to the outer surface of the side wall of the glass container and can detect the water temperature and water level inside the glass container 10 in a non-contact manner. It eliminates the need to open a through hole in the glass container 10 for inserting the temperature / level detection element into the glass container 10, which can effectively reduce the number of openings in the glass container 10, improve structural strength, and reduce the risk of breakage. At the same time, the liquid inside the glass container 10 will flow out through the liquid passage hole 11. By placing the detection head 13 adjacent to the liquid passage hole 11, the water temperature and water level can be detected more accurately.

[0077] In this embodiment, a metal part with good thermal conductivity can also be used to seal the liquid passage hole 11. When the liquid flows through the liquid passage hole 11 through the pipeline assembly 50, it can be detected by the temperature detection element adjacent to the liquid passage hole 11, which can further improve the accuracy of temperature detection.

[0078] refer to Figure 11 and Figure 12 The electric kettle 100 also includes a handle 15, which covers and conceals the temperature / liquid level detection element, the liquid inlet 11, and at least a portion of the tubing assembly 50. Specifically, the handle 15 has a corresponding receiving space inside, and at least a portion of the tubing assembly 50 can be accommodated inside the handle 15, so that the tubing assembly 50, the temperature / liquid level detection element, and the liquid inlet 11 are not visible from the outside, making the overall appearance more aesthetically pleasing.

[0079] refer to Figure 10 The electric kettle 100 also includes a shielding layer 14, coated on the outer surface of the glass container sidewall, with the coating area covering the location of the temperature / liquid level detection element. Specifically, after the handle 15 covers and shields the temperature / liquid level detection element, the shielding layer 14 further shields the element, preventing the user from observing it from other angles of the transparent glass container 10, thus improving the overall aesthetics. Simultaneously, the outer surface of the glass container 10 is relatively smooth, making it easy for the detection head 13 to fall off during direct attachment, affecting its use. The shielding layer 14 provides sufficient space for the detection head 13, ensuring it can reliably adhere to the outer surface of the glass container sidewall, thus guaranteeing effective detection.

[0080] refer to Figure 11 and Figure 12The electric kettle 100 also includes a circuit board 16, which is installed inside the handle 15. A temperature / liquid level detection element is connected to the circuit board 16. The circuit board 16 is also communicatively connected to the power socket 60 via a signal line. In some embodiments, the temperature / liquid level detection element may be directly electrically connected to the power socket 60 without going through the circuit board 16. In some embodiments, the chip of the temperature / liquid level detection element is installed on the circuit board 16, and the chip is electrically connected to the detection head 13 via a wire. The circuit board 16 is also communicatively connected to the power socket 60 via a signal line. Specifically, the heating element is electrically connected to the power socket 60, and the chip on the circuit board 16 can obtain water level / temperature information accordingly through the temperature / liquid level detection element. Meanwhile, circuit board 16 is also connected to the power connector 60 via a signal line. The power connector 60 is electrically connected to the heating element. Based on the current input to the heating element from the power connector 60, heating information such as the heating temperature and heating on / off status of the heating element can be obtained. Circuit board 16 can control the current input to the heating element from the power connector 60 according to the water level / temperature information and the heating information to control the working state of the heating element. For example, when the liquid level inside the glass container 10 is detected to be lower than a preset value, the heating element can be stopped to prevent dry burning. In addition, by installing circuit board 16 inside handle 15, the internal space of handle 15 can be fully utilized, making the overall structure more compact. It also facilitates the concealment of the wires connected to the temperature / liquid level detection element and helps to isolate the heating component 30 from circuit board 16, reducing the temperature of the environment in which circuit board 16 is located and improving the service life of circuit board 16. By setting circuit board 16 so that the output terminal of the temperature / liquid level detection element is connected to the power connector 60 through circuit board 16, the number of pins of the connection terminal of the temperature / liquid level detection element is reduced, simplifying the circuit layout.

[0081] refer to Figure 8 and Figure 13 The second end of the pipeline assembly 50 includes a connecting pipe 52. The liquid coupling 40 includes an adapter cap 41 and a water valve 43. The connecting pipe 52 is connected to the side wall opening of the adapter cap 41. The top of the adapter cap 41 passes through the limiting hole 83 located in the center of the positioning mounting part 80. The water valve 43 is connected to the bottom of the adapter cap 41 and is connected to the connecting pipe 52 through the internal cavity of the adapter cap 41.

[0082] refer to Figure 6 and Figure 8 The positioning mounting component 80 is provided with a limiting rod 84 at a position corresponding to the extension path of the connecting pipe 52. The limiting rod 84 abuts against the connecting pipe 52. The adapter cap 41 also includes a limiting edge 42, which is provided on the side wall of the adapter cap 41. The top of the limiting edge 42 abuts against the lower surface of the positioning mounting component 80.

[0083] Specifically, by inserting the top of the adapter cap 41 into the limiting hole 83, the top of the limiting edge 42 on the side wall of the adapter cap 41 abuts against the lower surface of the positioning mounting part 80 and the circumferential inner edge of the limiting hole 83, and the limiting rod 84 presses against the connecting pipe 52, the liquid coupling 40 can be fixed accordingly, thereby providing a stable liquid outlet / inlet channel between the glass container 10, the pipeline assembly 50 and the liquid coupling 40.

[0084] Further, refer to Figure 2 and Figure 14 The automatic liquid dispensing device 200 of this embodiment includes the electric kettle 100 described in this embodiment. The automatic liquid dispensing device 200 also includes a lower plug-in socket 120, which is matched with the upper plug-in socket 60 of the electric kettle 100.

[0085] refer to Figure 2 The ejector pin 121 is located in the center of the plug-in base 120, corresponding to the water valve 43 at the bottom of the electric kettle 100. It is configured to open the ball bearing 431 inside the water valve 43 to form a liquid passage. Specifically, the water valve 43 has a water passage 432 with a tapered opening towards the adapter cap 41. The ball bearing 431 is placed in this water passage 432, and when it is in the water passage 432, it will block the water passage 432. In this embodiment, the ball bearing 431 can be held in the water passage 432 by gravity, or a spring can be provided inside the adapter cap 41 to hold the ball bearing 431, further ensuring that the ball bearing 431 can be stably placed in the water passage 432.

[0086] When the upper plug 60 is plugged into the lower plug 120, the pin 121 in the lower plug 120 will push open the ball 431, making the water passage 432 unobstructed. At this time, the glass container 10, the pipeline assembly 50 and the liquid coupling 40 are interconnected, and liquid can be dispensed / injected.

[0087] When the upper plug-in connector 60 separates from the lower plug-in connector 120, the ejector pin 121 retracts, and the ball bearing 431 falls back into the water passage 432 under gravity to block the water passage 432. Alternatively, if a spring is installed inside the adapter cap 41, the spring can return to its original position after the ejector pin 121 retracts, thus keeping the ball bearing 431 in place and blocking the tapered opening of the water passage 432.

[0088] In this embodiment, the ejector pin 121 may also be fitted with a spring. When the upper plug-in seat 60 and the lower plug-in seat 120 are plugged in, the ejector pin 121 will be subjected to a downward force and move downward accordingly. The spring fitted on the ejector pin 121 will be compressed and deformed accordingly. At the same time, the ejector pin 121 will enter the water passage 432 to push open the ball bearing 431. After the upper plug-in seat 60 and the lower plug-in seat 120 are separated, the ball bearing 431 will automatically fall and block the water passage 432. At the same time, the spring fitted on the ejector pin 121 will restore its deformation, causing the ejector pin 121 to reset and move upward.

[0089] refer to Figure 14 The automatic liquid dispensing device 200 in this embodiment also includes a device base 201 and a liquid dispensing nozzle disposed on the device base 201. The lower plug-in base 120 is placed in the device base 201. After the lower plug-in base 120 and the upper plug-in base 60 are plugged into each other, they can be electrically connected to the heating component 30. At the same time, the ejector pin 121 will lift the ball 431 to form a liquid passage between the glass container 10, the pipeline assembly 50 and the liquid coupling 40. The device base 201 is provided with a pumping mechanism. The first interface of the pumping mechanism is connected to the internal space of the glass container 10 through the liquid coupling 40, and the second interface of the pumping mechanism is connected to the liquid dispensing nozzle.

[0090] In this configuration, as long as the user presses the relevant dispensing button, the liquid, pumped by the pumping mechanism, flows through the liquid coupling 40 and the pipeline assembly 50 from the liquid inlet 11 of the glass container 10. After passing through the liquid coupling 40 and the pumping mechanism, it finally flows out from the dispensing nozzle, achieving automatic dispensing. Alternatively, the liquid flow can be reversed to achieve automatic filling. In another embodiment, this automatic dispensing device 200 can also be an automatic dispensing device 200 with a water purification function, which can be achieved by adding a corresponding water purification component, thus realizing the automatic dispensing of purified water.

[0091] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
