Description

Technical Field

Automatic water dispensing devices usually include a base, a kettle that is electrically connected to the base, a dispensing spout that is connected to the kettle, a pumping mechanism, and a control panel. By operating the corresponding button on the control panel, the pumping mechanism can be activated to pump water from the kettle to the dispensing spout, without having to pick up the kettle to pour it out.

[0034] The core of this utility model is to provide an electric heating kettle for an automatic liquid dispensing device, which can avoid the problems of scale and yellowing, make cleaning easier, and allow the heating component to be separated from the liquid passage hole on the kettle body by a certain distance, thereby avoiding the phenomenon of cracking of the less strong liquid passage hole due to drastic temperature changes in the heating component, and ensuring better safety of the overall structure.

[0035] 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.

[0036] An embodiment of the electric heating kettle for an automatic liquid dispensing device provided by this utility model is as follows: Figure 1 As shown, Figure 1 This is a schematic diagram of an embodiment of an electric heating kettle for an automatic liquid dispensing device provided by this utility model. The electric heating kettle may include:

[0037] The kettle body 1 is a one-piece molded glass kettle body. This type of kettle body 1 has no seams, thus reducing hygiene dead spots and the probability of leakage. Since there are no seams, no adhesives or other organic materials are used, thus better ensuring food safety. The kettle body 1 has a liquid passage hole 11. This liquid passage hole 11 is located on the side of the kettle body 1 to connect the inside and outside of the kettle body 1, and is separated from the heating component 2. This reduces the impact of the heating component 4 at high temperatures on the structural strength of the liquid passage hole 11. In this embodiment, the heating component 2 is located at the bottom of the kettle body 1. The vertical distance between the center of the liquid hole 11 and the bottom wall of the pot body 1 is preferably 10mm to 50mm. The smaller this vertical distance, the more difficult the drilling process becomes, and the easier it is to damage the pot body 1. If the vertical distance is too large, that is, the opening position of the liquid hole 11 is higher, the water inlet or outlet position is higher, the required pipe assembly 4 is longer, which increases the difficulty of hiding the pipe assembly 4. Moreover, when water is drawn from the liquid hole 11, it is easy to cause a lot of residual liquid in the pot body 1 that cannot be discharged. The shape of the liquid 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.

[0038] Heating component 2 is used to heat the kettle body 1. Specifically, heating component 2 is located below the bottom surface of kettle body 1 and is in contact with kettle body 1. It is electrically connected to the relevant heating circuit. After the power is turned on, current flows through heating component 2, which can realize the conversion from electrical energy to heat energy. The generated heat energy can be transferred to the bottom surface of kettle body 1 through heat conduction and finally to the liquid inside kettle body 1, so that the temperature of the liquid continuously rises. Since heating component 2 is located below the bottom surface of kettle body 1, it is far away from the liquid passage hole 11 opened on the side of kettle body 1. This liquid passage hole 11 is the weakest area of ​​the integrally formed glass kettle body and is more likely to crack under the action of thermal expansion and contraction compared with other parts. By keeping it away from heating component 2, direct contact with high-temperature heating component 2 is avoided, which can reduce the occurrence of this problem and thus better ensure the safety of this electric heating kettle.

[0039] The liquid coupling 3 is separated from the heating component 2. This liquid coupling 3 can realize the liquid inlet operation of the kettle body 1, the liquid outlet operation of the kettle body 1, or a single liquid inlet or outlet operation. It can be set at a certain distance below the heating component 2 to avoid being affected by the high temperature of the heating component 2. Therefore, the liquid coupling 3 itself will not be overheated, softened and deformed due to high temperature, thus affecting its normal function, nor will it release gas due to overheating. The gap between the two can be achieved by a certain type of heat insulation component. The gap distance can be determined according to actual needs and is not limited here.

[0040] The piping assembly 4 has its first end passing through the liquid inlet 11 and communicating with the internal space of the kettle body 1. Its second end is connected to the liquid coupling 3 to sequentially connect the internal space of the kettle body 1, the piping assembly 4, and the liquid coupling 3. This piping assembly 4 has a certain length, and its function is to allow the liquid inside the kettle body 1 to flow out of the kettle while maintaining a certain distance between the liquid coupling 3 and the liquid inlet 11. The liquid coupling 3 can be connected to the relevant dispensing mechanism of the automatic dispensing device. In this case, when the user presses the relevant dispensing button of the automatic dispensing mechanism, the liquid coupling 3 can connect the entire liquid piping. Under the pumping action, the liquid in the internal space of the kettle body 1 can sequentially pass through the piping assembly 4, the liquid coupling 3, and the relevant dispensing mechanism, and then flow out from the dispensing spout. 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 dispensing of liquid from an all-glass kettle while ensuring hygiene and safety.

[0041] As can be seen from the above technical solution, the embodiment of the electric heating kettle for automatic liquid dispensing device provided by this utility model adopts an integrally molded glass kettle body. Compared with the existing solution that combines stainless steel parts and glass parts, it not only eliminates the splicing part between stainless steel and glass, but also reduces the problem of rough stainless steel surface and easy scaling, which can reduce the occurrence of scale and yellowing, and is more convenient to clean. Moreover, since the liquid passage hole 11 is separated from the heating component 2 by a certain distance, it can reduce the probability of the low-strength liquid passage hole 11 cracking due to drastic temperature changes in the heating component 2, ensuring that the overall structure has better safety. Furthermore, since the internal space of the kettle body 1, the pipe assembly 4 and the liquid coupling 3 are connected in sequence by the pipe assembly 4, the liquid coupling 3 can be connected to the pumping mechanism of the automatic liquid dispensing device, thus realizing automatic liquid dispensing.

[0042] Continue to refer to Figure 1In one specific embodiment of the aforementioned kettle body, the aforementioned pipeline assembly 4 may include a liquid-passing connector 41 and a connecting pipe 42 that are interconnected. The liquid-passing connector 41 passes through the liquid-passing hole 11 and extends into the internal space of the kettle body 1. One end of the liquid-passing connector 41 located in the internal space can be bent at a certain angle toward the bottom surface of the kettle and extend a certain distance toward the bottom surface of the kettle. This allows its end to be closer to the bottom of the kettle, thereby allowing the liquid at the bottom of the kettle body 1 to be pumped out, resulting in less liquid residue at the bottom of the kettle. Of course, this liquid-passing connector 41 can also adopt other bending forms according to actual needs, as long as it can guide the liquid inside the kettle body 1 through the kettle body to the connecting pipe 42 for liquid discharge. Moreover, the connecting pipe 42 is located in... The connecting tube 42 can be made of a relatively flexible material on the outside of the kettle body 1. This allows for easy bending while maintaining sufficient strength to prevent collapse under natural conditions that could affect liquid flow. This also facilitates free placement on the outside side and below the bottom of the kettle body 1. Liquid inside the kettle body 1 passes sequentially through the liquid inlet 41 and the connecting tube 42 to reach the liquid coupler 3. The length of the connecting tube 42 depends on the distance between the end of the liquid inlet 41 located on the outside of the kettle body 1 and the inlet end of the liquid coupler 3. The internal diameter can be determined based on the required liquid flow rate; a larger internal diameter can be used when a faster flow rate is needed, and vice versa. (Reference) Figure 1 and Figure 6 The electric kettle may also include a handle 102, and part of the piping assembly 4 can be housed within the handle 102. Specifically, the connecting pipe 42 is preferably hidden inside the handle 102, so that the connecting pipe 42 is not visible from the outside, making it more aesthetically pleasing. In some other cases, the liquid coupling 3 can also achieve the function of liquid inlet, in which case the entire liquid flow direction is reversed, which will not be elaborated here. It should also be noted that the liquid connector 41 can be made of inorganic materials, such as stainless steel, which will not rust and contaminate the liquid after prolonged immersion in liquid. It can also be made of organic materials that do not release harmful substances, which can be selected according to actual needs. The aforementioned connecting pipe 42 can be made of silicone, which has food-grade safety and will not pose a health risk to users. Moreover, this silicone connecting pipe can ensure a sealed connection with the liquid connector 41, ensuring that there is no leakage from the connection between the two. Of course, other materials can also be selected to make this piping assembly according to actual needs, and no restrictions are imposed here.

[0043] Further reference Figure 1It also includes a sealing ring 5, which has an inner ring surface 51 and an outer ring surface 52. This sealing ring 5 is installed between the pipe assembly 4 and the wall of the liquid inlet 11. The inner ring surface 51 abuts against the circumferential surface of the pipe assembly 4, ensuring a better seal and preventing leakage from this location. Furthermore, the outer ring surface 52 abuts against the wall of the liquid inlet 11, further enhancing the seal and preventing leakage. Therefore, using this sealing ring 5 improves the sealing effect of the most leak-prone part of this all-glass kettle, thereby further enhancing the safety of the kettle body 1. During installation… First, the sealing ring 5 can be fitted onto the outer periphery of the liquid-passing connector 41. Then, the liquid-passing connector 41 can be inserted into the liquid-passing hole 11, so that the sealing ring 5 is located between the pipeline assembly 4 and the hole wall of the liquid-passing hole 11. The inner ring surface 51 and the outer ring surface 52 of the sealing ring 5 are respectively pressed against the circumferential surface of the pipeline assembly 4 and the hole wall of the liquid-passing hole 11. The specific pressing method is not limited. For example, a deformable sealing ring 5 can be selected, whose radial thickness is slightly larger than the distance between the pipeline assembly 4 and the hole wall of the liquid-passing hole 11. After the sealing ring 5 is inserted into this space, an interference fit is formed, so it is not easy to fall off after tightening, and the sealing effect will be better.

[0044] Further, continue to refer to Figure 1The sealing ring 5 protrudes from the inner wall of the kettle body 1 on the side facing the internal space of the kettle body 1. That is, the sealing ring 5 extends a certain distance into the internal space of the kettle body 1. The electric heating kettle also includes a baffle 6, which is located inside the kettle body 1 and sleeved on the outside of the pipe assembly 4. This baffle 6 and the pipe assembly 4 can be fixed together. The baffle 6 and the side of the sealing ring 5 facing the internal space of the kettle body 1 are pressed together, so that the baffle 6 can press the side of the sealing ring 5 to better seal that part of the liquid passage hole 11; and / or the side of the sealing ring 5 away from the internal space of the kettle body 1 protrudes from the outer wall of the kettle body 1. That is, the sealing ring 5 can extend a certain distance outside the kettle body 1, so that after tightening, a certain degree of compression can be formed at this part, which can form a better sealing effect at this part; the end of the pipe assembly 4 that protrudes from the kettle body 1 is formed with external threads (not shown). A nut 7 is connected to the external thread. The nut 7 abuts against the side of the sealing ring 5 facing away from the internal space of the pot body 1. When the nut 7 is tightened to the pipe assembly 4, the pipe assembly 4 can drive the baffle 6 on it to continuously press the side of the sealing ring 5 facing the internal space of the pot body 1. In some cases, the sealing ring 5 can be pressed so tightly by the baffle 6 that it cannot be seen from the outside, achieving a greater degree of tightness and sealing effect in this part. The nut 7 can also continuously press the side of the sealing ring 5 facing away from the internal space of the pot body 1. In some cases, the side of the sealing ring 5 facing away from the internal space of the pot body 1 can also be pressed so tightly by the nut 7 that it cannot be seen from the outside, similarly achieving a greater degree of tightness and sealing effect in this part. Of course, in other cases, a part of both sides of the sealing ring 5 can be left visible from the outside, which can be selected according to actual needs.

[0045] Continue to refer to Figure 1 In one specific embodiment of this utility model, based on the above embodiment, it may further include a kettle base 8. This kettle base 8 is fixed to the kettle body 1. The space formed inside the kettle base 8 can accommodate the heating component 2, the liquid coupling 3, and a portion of the pipeline assembly 4. The kettle base 8 is provided with heat dissipation grooves in its circumference. Figure 1(Not shown) The shape of this heat dissipation groove can be rectangular, round, oval, etc., and other shapes and sizes can be selected according to actual needs. There are no restrictions here, as long as the interior of the kettle base 8 can exchange heat with the external environment. This heat dissipation groove can quickly dissipate the high-temperature gas inside the kettle base 8 to the surrounding environment, ensuring that the interior does not overheat, thereby further accelerating the heating speed of the liquid inside the kettle body 1; and / or the electric heating kettle may also include a heat insulation plate 9 disposed in the kettle base 8. This heat insulation plate 9 can thermally isolate certain components from the heating assembly 2 to avoid being affected by high temperature. The surface of the heat insulation plate 9 may have openings for heat dissipation. The heat vent 91 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 inside the heat insulation plate 9. When the liquid coupling 3 is located inside the kettle base 8, the heat insulation plate 9 separates the heating component 2 and the liquid coupling 3. This prevents the high temperature of the heating component 2 from affecting the liquid coupling 3, thus ensuring that the liquid coupling 3 can work normally for a longer period of time. The heat insulation plate 9 can have a certain height according to actual needs so that there is a sufficiently large distance between the heating component 2 and the liquid coupling 3. Of course, in some other embodiments, the liquid coupling 3 may not be located inside the kettle base 8.

[0046] As can be seen, the base 8 of the kettle body can protect the various internal components from damage caused by external impacts. Moreover, the central control circuit board of the kettle body 1 can be arranged inside the base 8. The central control circuit board can be connected to the temperature detection component and the liquid level detection component to obtain the corresponding temperature and liquid level signals and control related functions. The temperature detection component and the liquid level detection component can be installed on the kettle body 1. The temperature detection component can be used to detect the temperature of the liquid inside the kettle body 1 and display it, so that the user can know the liquid temperature in real time and avoid accidents such as scalding. The liquid level detection component can be used to detect the position of the liquid level inside the kettle body 1, which can provide a basis for whether the liquid needs to be added. During installation, both components can be covered with an insulating layer and placed on the outer wall of the kettle body 1. A first detection through-hole and a second detection through-hole can be opened on the side wall of the kettle body 1. The temperature detection component can extend into the kettle body 1 through the first detection through-hole to directly contact the liquid, thus making the temperature test more accurate. The liquid level detection component can extend into the kettle body 1 through the second detection through-hole to directly contact the liquid, which also ensures more accurate liquid level detection. This liquid level detection component can detect the liquid level based on pressure, capacitance signal, or other methods. There are no restrictions here. Of course, a third detection through-hole can also be opened on the liquid connector 41 or connecting pipe 42, so that the temperature detection component and the liquid level detection component can extend into the liquid connector 41 or connecting pipe 42 through the third detection through-hole. Alternatively, the temperature detection component and the liquid level detection component can also be inserted into the kettle body 1 without being fixed to the liquid connector 41 or connecting pipe 42. These can be selected according to actual needs. In some specific implementations, the central control circuit board may also have a temperature protection unit. This temperature protection unit is used to disconnect the heating component 2 from the power supply when the temperature of the heating component 2 exceeds the preset temperature. This can avoid the risk of fire caused by dry burning and better ensure the safety of the kettle during operation.

[0047] Further reference Figure 1 The base 8 of the kettle can accommodate the heating component 2; the heating component 2 may include a heating plate 21 and a thermally conductive adhesive 22 disposed between the heating plate 21 and the kettle body 1, and the heating plate 21 is bonded and fixed to the kettle body 1 by the thermally conductive adhesive 22.

[0048] Alternatively, the base 8 of the kettle body can house the heating component 2; the heating component 2 may include a heating plate 21, a thermally conductive adhesive 22 disposed between the heating plate 21 and the kettle body 1, and an enhanced thermally conductive layer 23 disposed between the thermally conductive adhesive 22 and the kettle body 1.

[0049] It should be noted that the thermally conductive adhesive 22 can be made of thermally conductive silicone. This type of thermally conductive silicone can not only firmly bond the heating plate 21 to the kettle body 1, but also has good thermal conductivity, which can quickly transfer the heat generated by the heating plate to the kettle body 1 to heat the liquid inside. Moreover, the enhanced thermal conductivity layer 23 can be a nano-coating, such as a nano-copper coating or a nano-aluminum coating, coated on the bottom surface of the kettle body 1. It has a large specific surface area, so it can enhance the heat transfer rate and allow the heat generated by the heating plate 21 to be conducted to the glass kettle body 1 more quickly, so as to achieve faster heating of the liquid inside the kettle. It should also be noted that when a glass kettle is used, a glass kettle with a flat bottom can be selected. The flatness tolerance of the bottom surface can preferably be 0.10mm to 0.50mm, and the bottom thickness can preferably be 1.0mm to 2.2mm. The heating plate is also preferably flat, and its surface flatness tolerance can preferably be 0.02mm to 0.30mm, and the smoothness can preferably be grade ▽2 or above.

[0050] Furthermore, the connection between the aforementioned liquid transfer connector 41 and the vessel body 1 can also be implemented in various other ways, see reference. Figure 2 , Figure 2 This is a schematic diagram of a second implementation of the connection between the liquid inlet connector and the kettle body. The first end of the liquid inlet connector 41 passes through the liquid inlet hole 11, and a first extension edge 411 is provided at the part of the liquid inlet connector 41 near the inner side wall 12 of the kettle body. The first extension edge 411 is connected to the inner side wall 12 of the kettle body. It can be seen that the first extension edge 411 can be kept parallel to the inner side wall 12 of the kettle body. Therefore, when the first extension edge 411 is fixed on the inner side wall 12, it can ensure sufficient sealing performance and prevent leakage from this part. The specific connection method is to apply glue locally between the two. It is preferable to apply glue in the middle part rather than at the edge of the first extension edge 411. This can ensure that the glue is ultimately sealed inside and will not come into contact with the liquid. In addition, a sealing ring can be added between the first extension edge 411 and the inner side wall 12 to enhance the sealing performance, depending on actual needs.

[0051] Or, refer to Figure 3 , Figure 3 This is a schematic diagram of a third implementation of the connection between the liquid transfer connector and the kettle body. The first end of the liquid transfer connector 41 is provided with a second extension edge 412 near the outer wall 13 of the kettle body. The second extension edge 412 is connected to the outer wall 13 of the kettle body. Specifically, it can be seen that the second extension edge 412 is parallel to the outer wall 13 of the kettle body to achieve a tight connection and ensure that there is no leakage. Moreover, a sealing ring can be added between the second extension edge 412 and the outer wall 13 according to actual needs to further enhance the sealing performance.

[0052] refer to Figure 4 , Figure 4This is a schematic diagram of a fourth implementation of the connection between the liquid transfer connector and the kettle body. The first end of the liquid transfer connector 41 passes through the liquid passage hole 11. A first sealing ring 413 and a first fixing member 414 for tightly contacting the first sealing ring 413 with the inner wall 12 of the kettle body are fitted onto the portion of the liquid transfer connector 41 near the outer wall 13 of the kettle body. A second sealing ring 415 and a second fixing member 416 for tightly contacting the second sealing ring 415 with the outer wall 13 of the kettle body are fitted onto the portion of the liquid transfer connector 41 near the outer wall 13 of the kettle body. In a specific implementation, threads can be provided on the liquid transfer connector 41 at positions corresponding to the first fixing member 414 and the second fixing member 416. 6 can be a bolt. When connecting and tightening, the first sealing ring 413 can be put on the liquid inlet 41 and close to the inner wall 12 of the pot body. Then, the second sealing ring 415 can be put on the liquid inlet 41 and close to the outer wall 13 of the pot body. Then, the first fastener 414 can be put on the liquid inlet 41 and tightened. This can fix the first sealing ring 413 to the inner wall 12 tightly together. Finally, the second fastener 416 can be put on the liquid inlet 41 and tightened. This can fix the second sealing ring 415 to the outer wall 13 tightly together. In this way, sealing and firm connection are achieved from both the inside and outside of the pot body. This redundant design can ensure that the pot body's sealing performance is maintained for a longer time.

[0053] Or, refer to Figure 5 , Figure 5 This is a schematic diagram of a fifth implementation of the connection between the liquid transfer connector and the kettle body. The first end of the liquid transfer connector 41 passes through the through hole 11, and a third extension edge 410 is provided at the part of the liquid transfer connector 41 near the inner wall 12 of the kettle body. The third extension edge 410 is connected to the inner wall of the kettle body by a sleeved third sealing ring 417. A fourth sealing ring 418 and a third fixing member 419 are sleeved at the part of the liquid transfer connector 41 near the outer wall 13 of the kettle body for tightly contacting the fourth sealing ring 418 and the outer wall 13 of the kettle body and for tightly contacting the third sealing ring 417 and the inner wall 12 of the kettle body. Specifically, the third fixing member 419 can be attached to the liquid transfer connector 41. The fixing part 419 is threaded at the corresponding position. The third fixing part 419 can be a bolt. In this case, when the third fixing part 419 is tightened, the threaded engagement can drive the liquid connector 41 to move to the outside of the kettle body. This can drive the first extension edge 411 to press the third sealing ring 417 onto the inner wall 12, thereby achieving sealing and fixing of the inner wall. Finally, the third fixing part 419 can press the fourth sealing ring 418 onto the outer wall 13, thereby achieving sealing and fixing of the outer wall. It can be seen that in this implementation method, only one fixing part is used to achieve simultaneous sealing and fixing of the inner and outer walls of the kettle body, which saves production costs.

[0054] In addition, the connection between the liquid inlet connector 41 and the pot body 1 can also be implemented in a sixth way. In this way, the pot body 1 can preferably be a glass pot body, the liquid inlet connector 41 can preferably be a glass liquid inlet connector, and the glass liquid inlet connector and the glass pot body are connected together by welding. This way, the two can be fixed into a whole, so as to ensure that the connection between the two is more sealed and firm. Specifically, this whole can be manufactured directly during the initial manufacturing, or the glass pot body can be manufactured first, and then the glass liquid inlet connector 41 can be connected to the all-glass pot body 1 into a whole by welding.

[0055] In another specific embodiment of the electric kettle for the automatic liquid dispensing device described above, a filter screen can be fixed at the first end of the pipeline assembly 4. This allows the liquid to be filtered before it reaches the first end of the pipeline assembly 4, preventing impurities in the liquid from entering the pipeline assembly 4 and further improving the hygiene of the liquid. In one specific implementation, the pore size of the filter screen is preferably 0.2mm to 1.0mm, for example, 0.2mm, 0.5mm, 0.8mm, 1.0mm, etc. The appropriate pore size can be selected according to actual needs. The smaller the pore size, the finer the filtration. Other pore sizes outside this range can also be selected, which is not limited here.

[0056] refer to Figure 6 , Figure 6 This is an overall schematic diagram of the automatic liquid dispensing device and the electric kettle. The automatic liquid dispensing device 10 includes a device base 101 and a liquid dispensing nozzle disposed on the device base 101. Figure 6 (Not shown), the device base 101 is electrically connected to the heating component 2, and the device base 101 is equipped with a pump mechanism ( Figure 6 (Not shown), the first interface of the pump mechanism is connected to the internal space of the pot body 1 through the liquid coupling 3, and the second interface of the pump mechanism is connected to the liquid outlet.

[0057] In this configuration, as long as the user presses the relevant dispensing button, the liquid coupling 3 is activated. Liquid, pumped by the pumping mechanism, flows through the pipe assembly 4 from the through-hole 11 of the kettle body 1, then through the liquid coupling 3 and the pumping mechanism, finally flowing out from the dispensing nozzle. This achieves automatic dispensing. Alternatively, the liquid flow can be reversed to achieve automatic filling. In another implementation, this automatic dispensing device can also be a water purification device, which can be achieved by adding appropriate water purification components, thus enabling automatic dispensing of purified water.
