Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to a liquid heating container. Background Technology

[0002] In existing liquid heating containers, such as electric kettles, the solubility of dissolved air decreases as the temperature gradually rises during the initial heating process. These gases expand upon heating and escape from the liquid, forming small bubbles. As the liquid approaches its boiling point, the water at the bottom rapidly vaporizes into steam. This steam condenses into small bubbles and, due to its lower density than water, floats to the surface, vibrating and producing a hissing sound. When the liquid reaches its boiling point and begins to boil, the formation and rise of bubbles become very vigorous. The water at the bottom continues to vaporize, forming numerous steam bubbles. These bubbles may merge into larger bubbles as they rise and burst upon reaching the surface, releasing a large amount of steam, resulting in a loud gurgling sound. This excessive noise negatively impacts the user experience.

[0003] Therefore, providing a liquid heating container that operates relatively quietly during use has become a problem that needs to be solved. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a liquid heating container, wherein the liquid heating container includes a container body, a heating part, and a noise suppression part. The container body has a receiving cavity; the heating part is disposed below the bottom wall of the container body for heating the bottom wall of the container body; the noise suppression part is disposed in the receiving cavity and located at the bottom of the receiving cavity, and the noise suppression part has a roughness Ra value on an uneven surface at the millimeter level, for reducing or suppressing bubbles generated by the liquid heating container when heating the liquid.

[0005] According to the liquid heating container provided in this embodiment, when the heating unit is working, it can heat the bottom wall of the container body and heat the liquid in the containment cavity through heat transfer. As heating continues, the temperature of the liquid in the containment cavity gradually increases, and bubbles begin to form inside the liquid heating container. Because the noise suppression part provided in the containment cavity has a roughness Ra value on the order of millimeters, this roughness Ra surface can reduce or suppress the bubbles generated by the liquid heating container when heating the liquid. Compared with existing liquid heating containers that can generate large bubbles, the liquid heating container of this application produces relatively less noise during the escape of small bubbles, achieving noise reduction and quieter operation, thereby improving the user experience.

[0006] In some embodiments, the roughness Ra value of the uneven surface is 1mm-5mm.

[0007] In these embodiments, the uneven surface with a roughness Ra value of a preset value can further improve the suppression effect on the size of bubbles generated by the liquid heating container when heating the liquid, and can be manufactured based on the existing powder sintering method, so as to simplify the manufacturing of the noise suppression part, thereby simplifying the manufacturing of the liquid heating container.

[0008] In some embodiments, the uneven surface includes a recessed region and a protruding region, the surfaces of which are respectively uneven. This further refines the surface structure of the noise suppression section, thereby further reducing the size of the formed bubbles (avoiding the formation of large bubbles) and improving the noise reduction effect. Simultaneously, the uneven surface increases the contact area with the liquid, resulting in high heat transfer efficiency and thus improving the heating efficiency of the liquid heating container.

[0009] In some embodiments, the noise suppression part is a molecular sieve plate, and the projection of the molecular sieve plate on the bottom wall of the container body at least covers the area corresponding to the heating part. Positioning the molecular sieve plate relative to the heating part maximizes its use in suppressing bubble size, thereby improving noise reduction.

[0010] In some embodiments, the molecular sieve plate is in contact with the bottom wall of the container body, and the upper surface of the molecular sieve plate has an uneven surface with a roughness Ra value on the order of millimeters. During the heating process of the liquid heating container, the upper surface of the molecular sieve plate serves as a bubble-forming surface. Due to its uneven surface with a roughness Ra value on the order of millimeters, the size of the formed bubbles can be limited, thereby achieving the purpose of noise reduction.

[0011] In some embodiments, the heating element is annular, and the molecular sieve plate is circular with a central hollow area that allows liquid to pass through. This reduces the amount of raw materials required for manufacturing while ensuring noise reduction, thereby lowering the manufacturing cost of the liquid heating container. The central hollow area also ensures normal liquid flow, improving the safety of the liquid heating container during use. The molecular sieve plate is detachably installed within the container body, thus improving assembly efficiency and facilitating maintenance and replacement.

[0012] In some embodiments, the molecular sieve plate has a predetermined distance H between itself and the bottom wall corresponding to the heating element. The lower surface of the molecular sieve plate and the sidewall of the central hollow area are uneven surfaces with a roughness Ra value on the order of millimeters. During the heating process of the liquid heating container, large bubbles are not generated due to the distance limitation between the molecular sieve plate and the bottom wall area corresponding to the heating element. Furthermore, small and medium-sized bubbles that are generated are broken down into smaller bubbles by the lower surface of the molecular sieve plate and the lower end of the sidewall of the central hollow area. At this time, the molecular sieve plate is equivalent to a bubble-breaking plate. Through the blocking and breaking effect of the molecular sieve plate, small and medium-sized bubbles can be effectively destroyed and the formation of large bubbles can be suppressed, thereby reducing noise.

[0013] In some embodiments, the molecular sieve plate is mounted on the side wall or bottom wall of the container body, and a preset distance H is provided between it and the bottom wall region corresponding to the heating part, wherein 0 mm < H ≤ 5 mm. In other embodiments, the outer side of the molecular sieve plate is mounted on the outer peripheral edge region of the bottom wall, and in the region corresponding to the heating part, the lower surface of the molecular sieve plate is provided with the preset distance H between it and the bottom wall, wherein 0 mm < H ≤ 5 mm.

[0014] In these embodiments, molecular sieve plates can be mounted on the side or bottom wall of the container body in various forms to better accommodate the installation requirements of some existing liquid heating containers.

[0015] In some embodiments, the central hollow area is circular, and the radius of the circle does not exceed 2cm. This allows liquid to pass through normally while ensuring noise suppression, thus ensuring the safety of the liquid heating container. At the same time, the circular design also maintains the aesthetic appearance of the liquid heating container and enhances the overall aesthetics of the product.

[0016] In some embodiments, the molecular sieve plate is sintered from molecular sieve particles with rough surfaces. By densely packing these rough-surfaced particles, the molecular sieve plate can, on the one hand, utilize the rough surfaces of the molecular sieve particles to produce a molecular sieve plate with a surface roughness Ra value on the order of millimeters. On the other hand, the internal pores of the molecular sieve particles can balance the heating conditions at the bottom of the liquid heating container, preventing bubbles from forming due to localized overheating at the bottom, thereby further reducing the noise of the liquid heating container.

[0017] In some embodiments, the molecular sieve particles have a particle size of 2 micrometers to 10 micrometers, which can facilitate the formation of a molecular sieve plate with the required density of molecular sieve particles to achieve noise reduction.

[0018] In some embodiments, the pore size of the molecular sieve particles is If the pore size of the molecular sieve plate is smaller than This means that the pore size of the molecular sieve itself is too small, and its effect on balancing the heating uniformity at the bottom of the liquid heating container is not significant, thus its noise reduction effect is also not significant; if the pore size of the molecular sieve plate is larger than... This means that the pores of the molecular sieve itself are too large, and its effect on balancing the heating uniformity of the bottom of the liquid heating container is not obvious. Therefore, the effect of improving noise reduction is not obvious, and it will also affect the strength of the molecular sieve plate.

[0019] In some embodiments, the molecular sieve particles include one of sodium-based molecular sieve particles, potassium-based molecular sieve particles, and calcium-based molecular sieve particles, which can form molecular sieve plates of various types, enabling the manufacture of multiple types of liquid heating containers, thereby expanding the types of liquid heating containers and allowing for preferential settings based on actual needs.

[0020] In some embodiments, the thickness of the molecular sieve plate is 0.3cm-1cm, which can meet the strength requirements of the molecular sieve plate and is easy to install and use. Attached Figure Description

[0038] Furthermore, in the description of the examples, detailed descriptions of well-known related components or functions will be omitted when it is believed that such detailed descriptions would lead to a vague interpretation of the present invention.

[0039] The following will combine Figures 1 to 5 This invention introduces a liquid heating container provided by an embodiment of the present invention.

[0040] An embodiment of the present invention provides a liquid heating container, wherein the liquid heating container includes a container body 10, a heating part 30, and a noise suppression part 20. Wherein, as... Figures 1 to 4 As shown, the container body 10 has a receiving cavity, the heating part 30 is disposed below the bottom wall 11 of the container body 10 for heating the bottom wall 11 of the container body 10, and the noise suppression part 20 is disposed in the receiving cavity and located at the bottom of the receiving cavity. The noise suppression part 20 has a rough surface 21 with a roughness Ra value of millimeters for reducing or suppressing bubbles generated by the liquid heating container when heating liquid.

[0041] According to the liquid heating container provided in this embodiment, when the heating unit 30 is working, it can heat the bottom wall of the container body 10 and heat the liquid in the containment cavity through heat transfer. As heating continues, the temperature of the liquid in the containment cavity gradually increases, and bubbles begin to be generated in the liquid heating container. Since the noise suppression unit 20 provided in the containment cavity has a roughness Ra value of millimeters on an uneven surface 21, this uneven surface 21 can reduce or suppress the bubbles generated by the liquid heating container when heating the liquid. Compared with the liquid heating containers of the prior art that can generate large bubbles, the liquid heating container of this application produces relatively little noise during the escape of small bubbles generated in the process of use, which can achieve the purpose of noise reduction and is quieter, thereby improving the user experience.

[0042] According to this invention, the noise suppression part 20 has a roughness Ra value on a millimeter-level uneven surface 21. As an example, the roughness Ra value of the uneven surface 21 is 1mm-5mm. Further, the roughness Ra value of the uneven surface 21 is 1mm-2mm, 1mm-3mm, 1mm-4mm, 2mm-3mm, 2mm-4mm, 2mm-5mm, 3mm-4mm, 3mm-5mm, or 4mm-5mm.

[0043] In these embodiments, the uneven surface 21 with a roughness Ra value of a preset value can further improve the suppression effect on the size of bubbles generated by the liquid heating container when heating the liquid, and can be manufactured based on existing powder sintering methods, thereby simplifying the manufacturing of the noise suppression part 20 and thus simplifying the manufacturing of the liquid heating container. Of course, it should be noted that this utility model does not limit the manufacturing method of the noise suppression part 20 with uneven surface 21. Those skilled in the art can also choose other modifications under the teachings of this application, such as obtaining the noise suppression part 20 with uneven surface 21 by sandblasting, machining, and chemical etching.

[0044] In some embodiments, the uneven surface 21 includes a recessed region 211 and a protruding region 212, the surfaces of which are respectively uneven. This further refines the surface structure of the noise suppression part 20, thereby further reducing the size of the formed bubbles (avoiding the formation of large bubbles) and improving the noise reduction effect. At the same time, the uneven surface can increase the contact area with the liquid, resulting in high heat transfer efficiency, thereby improving the heating efficiency of the liquid heating container.

[0045] like Figure 5 As shown, the surface of each protruding region 212 and recessed region 211 is uneven; in other words, the surface of each protruding region 212 and recessed region 211 is not smooth, but has a series of protrusions and depressions.

[0046] In these embodiments, the surface of the noise suppression unit 20 not only includes a primary uneven structure, but also has multiple secondary uneven structures distributed on each primary uneven structure, thereby forming a multi-layered uneven surface 21. In this invention, the uneven surface 21 is the aforementioned primary uneven structure, and the uneven surface is the aforementioned secondary uneven structure. The primary uneven structure can reduce the size of the bubbles to reduce noise, while the secondary uneven structure can further reduce the size of the bubbles, optimize the noise reduction effect, and thus improve the user experience.

[0047] As a specific example, the unevenness is at the micrometer level; specifically, the unevenness is an unevenness with a roughness Ra value of 2-5 micrometers.

[0048] According to this application, the noise suppression part 20 is a molecular sieve plate. Hereinafter, the noise suppression part 20 according to this invention will be described in detail with reference to the molecular sieve plate, so as to make the content of this invention more complete.

[0049] In some embodiments, the noise suppression part 20 is a molecular sieve plate. Using a molecular sieve plate as the noise suppression part 20 makes it easy to manufacture a noise suppression part 20 with a roughness Ra value on the order of millimeters, thereby reducing or suppressing bubbles generated by the liquid heating container when heating the liquid, thus achieving the purpose of noise reduction. Furthermore, if necessary, a molecular sieve plate with a further refined rough structure can be formed by stacking molecular sieve particles with rough surfaces to further optimize the noise reduction effect.

[0050] In existing technologies, during the heating process of a liquid in a liquid heating container (initial heating, near boiling, or boiling stage), the generated bubbles are mainly concentrated in the area corresponding to the heating component (or heating element). Specifically, taking the boiling stage as an example, the heat generated by the heating component during operation causes the liquid temperature in that area to rise rapidly, reaching or exceeding the liquid's boiling point, thereby triggering the formation of a large number of bubbles.

[0051] In some embodiments, the projection of the molecular sieve plate onto the bottom wall 11 of the container body 10 at least covers the area corresponding to the heating part 30. Here, the heating part 30 can also be referred to as a heating element. As an example, the heating element includes one of a heating wire, a heating tube, and a heating plate. The "area corresponding to the heating part 30" here can refer to the area enclosed by the heating element, which is the area where heat and bubbles are most concentrated. By aligning the molecular sieve plate with the heating part 30, this invention can maximize the use of the molecular sieve plate to suppress the size of bubbles, thereby achieving the purpose of improving and reducing noise.

[0052] According to an embodiment of the present invention, the outline of the molecular sieve plate is adapted to the outline of the heating part 30. Thus, after the two are installed in their corresponding positions, it is easy to ensure that the projection of the molecular sieve plate on the bottom wall 11 of the container body 10 at least covers the area corresponding to the heating part 30.

[0053] According to this utility model, the molecular sieve plate can be in complete contact with the bottom wall 11 of the container body 10, so as to serve as the bottom of the liquid heating container together with the bottom wall 11 of the container body 10, or it can be at a preset distance from the bottom wall 11 of the container body 10. Both of these settings can suppress the size of bubbles and reduce noise, thereby improving the user experience.

[0054] The liquid heating container of this utility model will be described in detail below with reference to the embodiments.

[0055] According to a first aspect of this invention, the projection of the molecular sieve plate onto the bottom wall 11 of the container body 10 at least covers the area corresponding to the heating part 30. The molecular sieve plate can be in complete contact with the bottom wall 11 of the container body 10, serving together with the bottom wall 11 of the container body 10 as the bottom wall of the liquid heating container. In this case, the upper surface of the molecular sieve plate serves as the upper surface of the bottom wall of the liquid heating container, and bubbles are formed on the upper surface of the molecular sieve plate during operation of the liquid heating container. Compared to a liquid heating container with an in-plane bottom wall, a liquid heating container with an inner bottom wall having a rough surface 21 at the millimeter level provides more bubble nucleation points due to the roughness, thus limiting the size of the bubbles in the early stages of formation and making it less likely for them to grow into excessively large bubbles. That is, a liquid heating container with a bottom wall having a rough surface at the millimeter level will limit the size of the bubbles during heating, making it easier to form smaller bubbles. These small bubbles rise relatively slowly in the liquid, reducing disturbance on the liquid surface and thus helping to reduce noise. In addition, during the boiling stage, as bubbles are continuously generated and rise, influenced by the flow of heated liquid and the interaction between bubbles, although bubbles generated at a certain position on the bottom wall at different times may merge at a certain height in the containment cavity during the continuous heating of the liquid heating container to form relatively large bubbles, the overall size of the merged bubbles will be smaller than that in the prior art because the size of the formed bubbles is relatively small. Thus, the noise generation can be further reduced due to the relatively small overall size of the accumulated bubbles.

[0056] In addition, when the molecular sieve plate is in complete contact with the bottom wall, the molecular sieve plate can be formed with uniform heating by means of its own pore structure, so as to balance the heating uniformity of the bottom of the liquid heating container, avoid local overheating affecting the size of the generated bubbles, and thus further reduce noise.

[0057] Furthermore, it should be noted that although a rough surface may increase the number of bubbles formed to some extent, the impact of the number is negligible compared to the impact of the size. The main advantage of this application lies in the small size of the formed bubbles. Small bubbles produce relatively less noise during their escape, thus achieving noise reduction and resulting in a quieter liquid heating container, improving the user experience.

[0058] Based on bubble diameter, small bubbles are denoted as R1, medium bubbles as R2, and large bubbles as R3, where R1 is less than 1 mm, 1 mm ≤ R2 ≤ 5 mm, and R3 > 5 mm. Existing liquid heating containers typically form large, small, and medium bubbles. Compared to existing technologies, the bubble size formed by the liquid heating container according to this invention can be effectively suppressed, resulting in mostly small bubbles and a small number of medium bubbles. Therefore, compared to existing technologies, this invention can effectively reduce bubble size, thereby reducing noise during use and improving the user experience.

[0059] In some embodiments, the molecular sieve plate is in contact with the bottom wall 11 of the container body 10, and the upper surface of the molecular sieve plate is a roughness Ra surface 21 with a roughness Ra value on the order of millimeters. Specifically, the molecular sieve plate with a roughness Ra surface 21 on the order of millimeters is disposed on the bottom wall 11 of the container body 10 and forms a tight fit with the bottom wall 11 of the container body 10. During the heating process of the liquid heating container, the upper surface of the molecular sieve plate serves as a bubble formation surface. Because it has a roughness Ra surface 21 with a roughness Ra value on the order of millimeters, it can limit the size of the formed bubbles, thereby achieving the purpose of noise reduction.

[0060] According to this invention, a molecular sieve plate is installed in a container body 10. In some embodiments, the molecular sieve plate is detachably installed in the container body 10, which improves assembly efficiency and facilitates maintenance and replacement. Specifically, during assembly, a receiving groove can be pre-formed on the side wall 12 of the container body 10. When assembling the liquid heating container, the molecular sieve plate can be placed in the receiving groove and pressed against the side wall 12 of the container body 10 by the bottom wall 11 of the container body 10. In other embodiments, the molecular sieve plate is fixedly installed in the container body 10, which ensures the stability of the molecular sieve plate installation and prevents it from moving during liquid heating, thus avoiding any impact on the suppression of bubbles.

[0061] As an example, the heating element 30 is annular, and the molecular sieve plate can be circular or have a central hollow structure. When the molecular sieve plate has a central hollow structure, the size of the hollow portion is no larger than the central area of ​​the bottom wall 11 (the central area of ​​the bottom wall 11 is the area not covered by the heating element 30; since the heating element 30 is not present in this area, large bubbles will not be generated, and therefore the noise suppression element 20 does not need to be provided). This reduces manufacturing materials while ensuring noise reduction, thereby lowering the manufacturing cost of the liquid heating container. As a specific example, the molecular sieve plate can be annular, and correspondingly, the central hollow area is circular, with a diameter not exceeding 2 cm. This allows for normal liquid flow while ensuring noise suppression, guaranteeing the safety of the liquid heating container. Simultaneously, the circular design maintains the aesthetic appearance of the liquid heating container, enhancing the overall aesthetic appeal of the product. It should be noted that the shape of the central hollow portion can be square, circular, or elliptical; this invention does not impose further limitations on this.

[0062] like Figure 3 and Figure 4 As shown, the liquid heating container includes a container body 10, a heating element 30, and a noise suppression element 20. The container body 10 has a receiving cavity. The heating element 30 is disposed below the bottom wall 11 of the container body 10 and is used to heat the bottom wall 11. The molecular sieve plate is circular and is disposed in the receiving cavity at the bottom of the cavity. Specifically, the upper surface of the molecular sieve plate has a surface roughness Ra value on the order of millimeters, and the lower surface is in close contact with the upper surface of the bottom wall, together with the bottom wall 11 forming the bottom wall of the liquid heating container. In use, the heat generated by the heating element is uniformly transferred to the molecular sieve plate through the bottom wall, raising the temperature of its upper surface, promoting the vaporization of the internal liquid, and forming microbubbles on the upper surface of the molecular sieve plate.

[0063] In some embodiments, the molecular sieve plate is a sintered molecular sieve plate, specifically formed by sintering molecular sieve particles with rough surfaces. By densely packing these rough-surfaced molecular sieve particles, the molecular sieve plate can, on the one hand, utilize the rough surfaces of the molecular sieve particles to create a surface with a roughness Ra value on the order of millimeters. On the other hand, the internal pores of the molecular sieve particles can balance the heating conditions at the bottom of the liquid heating container, preventing bubbles from forming due to localized overheating at the bottom, thereby further reducing the noise of the liquid heating container. As an example, the roughness Ra value of the rough surface of the molecular sieve particles is 2 micrometers to 5 micrometers.

[0064] In some embodiments, the particle size of the molecular sieve particles is 2 micrometers to 10 micrometers, which can facilitate the formation of the required molecular sieve plate by means of the close packing of molecular sieve particles, so as to achieve the purpose of noise reduction.

[0065] In some embodiments, the pore size of the molecular sieve particles is If the pore size of the molecular sieve plate is smaller than This means that the pore size of the molecular sieve itself is too small, and its effect on balancing the heating uniformity at the bottom of the liquid heating container is not significant, thus its noise reduction effect is also not significant; if the pore size of the molecular sieve plate is larger than... This means that the pores of the molecular sieve itself are too large, and its effect on balancing the heating uniformity of the bottom of the liquid heating container is not obvious. Therefore, the effect of improving noise reduction is not obvious, and it will also affect the strength of the molecular sieve plate.

[0066] In some embodiments, the molecular sieve particles include one of sodium-based molecular sieve particles, potassium-based molecular sieve particles, and calcium-based molecular sieve particles, and the types of molecular sieves that can form molecular sieve plates are diverse, enabling the manufacture of various types of liquid heating containers, thereby expanding the types of liquid heating containers and allowing for preferential settings based on actual needs.

[0067] In some embodiments, the thickness of the molecular sieve plate is 0.3cm-1cm, which can meet the strength requirements of the molecular sieve plate and is easy to install and use.

[0068] According to a second aspect of the present invention, the molecular sieve plate may also have a predetermined distance from the bottom wall 11 of the container body 10 corresponding to the heating part 30. The projection of the molecular sieve plate on the bottom wall 11 of the container body 10 at least covers the area corresponding to the heating part 30. This predetermined distance can limit / destroy the generation of large bubbles (here, the molecular sieve plate is equivalent to a bubble-breaking plate), thereby reducing the size of bubbles generated by the liquid heating container during the heating process, thus achieving the purpose of noise reduction. It should be noted that, according to the second aspect of the present invention, except for the difference in the installation position and shape requirements of the molecular sieve plate compared with the first aspect of the present invention, other aspects can be referred to the relevant description of the molecular sieve plate according to the first aspect of the present invention. Specifically, for the manufacturing material and thickness of the molecular sieve plate, please refer to the relevant description of the molecular sieve plate according to the first aspect of the present invention. The differences will be described in detail below, while the similarities will not be repeated.

[0069] As an example, the heating element 30 is annular, the molecular sieve plate is circular, and it has a central hollow area that allows liquid to pass through. As an example, the size of the central hollow area is no larger than the central area of ​​the bottom wall 11, where the central area of ​​the bottom wall 11 is the area not covered by the heating element 30. Since this area does not have the heating element 30, large bubbles will not be generated, thus eliminating the need for the noise suppression element 20. In this way, while ensuring noise reduction, manufacturing materials can be reduced, thereby lowering the manufacturing cost of the liquid heating container. Furthermore, the central hollow area ensures normal liquid flow, improving the safety of the liquid heating container. As a specific example, the shape of the central hollow area can be square, circular, or elliptical; this invention does not impose further limitations on this. More specifically, the molecular sieve plate can be annular, and the diameter of the central hollow area does not exceed 2 cm.

[0070] like Figure 1 and Figure 2 As shown, the liquid heating container includes a container body 10, a heating element 30, and a noise suppression element 20. The container body 10 has a receiving cavity, and the heating element 30 is disposed below the bottom wall 11 of the container body 10 for heating the bottom wall 11. A molecular sieve plate has a central hollow area that allows liquid to pass through. It is disposed in the receiving cavity and located at the bottom of the cavity. Specifically, it is installed on the side wall of the container body 10 and has a predetermined distance H between it and the bottom wall corresponding to the heating element 30. The lower surface and inner surface of the molecular sieve plate have a roughness Ra value on the order of millimeters, used to break up small and medium-sized bubbles and suppress the formation of large bubbles.

[0071] In some embodiments, the molecular sieve plate has a predetermined distance H between itself and the bottom wall 11 corresponding to the heating section 30. The lower surface of the molecular sieve plate and the sidewall of the central hollow area have a surface roughness Ra value on the order of millimeters. During the heating process of the liquid heating container, large bubbles are not generated due to the distance limitation between the molecular sieve plate and the bottom wall area corresponding to the heating section 30. Furthermore, the generated small and medium bubbles are broken down into smaller bubbles by the lower surface of the molecular sieve plate and the lower end of the sidewall of the central hollow area. At this time, the molecular sieve plate is equivalent to a bubble-breaking plate. Through the blocking and breaking effect of the molecular sieve plate, small and medium bubbles can be effectively destroyed and the formation of large bubbles can be suppressed, thereby reducing noise.

[0072] According to this utility model, molecular sieve plates can be installed on the side wall 12 or bottom wall 11 of the container body 10 in various forms to better adapt to the installation requirements of some existing liquid heating containers.

[0073] In some embodiments, the molecular sieve plate is installed on the side wall 12 or bottom wall 11 of the container body 10, and there is a preset distance H between it and the bottom wall area corresponding to the heating part 30, wherein 0mm < H ≤ 5mm.

[0074] In other embodiments, the outer side of the molecular sieve plate is installed on the outer peripheral edge region of the bottom wall 11. In the region corresponding to the heating part 30, there is a preset distance H between the lower surface of the molecular sieve plate and the bottom wall 11, wherein 0 mm < H ≤ 5 mm.

[0075] like Figure 1 As shown, the edge of the bottom wall 11 has a boss that protrudes upward relative to the middle region of the bottom wall 11. The outer side of the molecular sieve plate is supported on the boss and abuts against the side wall 12. The inner side of the molecular sieve plate is disposed on the middle region of the bottom wall 11 and has a preset distance H between it and the bottom wall 11 of the container body 10.

[0076] According to this utility model, the liquid heating container includes one of an electric kettle, a soy milk maker, a blender, a tea maker, and a coffee maker, which can solve the noise problems of the above-mentioned small household appliances during use.

[0077] While the embodiments of the present invention have been described in detail above, those skilled in the art can make various modifications and variations to the embodiments of the present invention without departing from the spirit and scope thereof. However, it should be understood that, in the view of those skilled in the art, these modifications and variations will still fall within the spirit and scope of the embodiments of the present invention as defined in the claims.
