Description

Technical Field

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

[0002] Currently, liquid heating containers such as electric kettles, food processors, soy milk makers, and electric kettles are widely used in household life. Due to the excellent light transmittance of glass, for liquid heating containers with glass bodies, a shielding part is provided to cover the working components below the container body. This shielding part is usually located on the horizontal wall surface after the lower end of the glass container body is bent inwards, for example, the textured shielding in Chinese patent CN219629334U or the frosted shielding in CN 208371545 U. At the same time, to improve the accuracy of water level detection and temperature measurement, water level sensors, temperature sensors, and other detection elements are usually installed on the outer wall of the container body. To improve the overall craftsmanship and user experience of the container, a vertical shielding film is printed along the height of the container body to cover the detection elements.

[0003] However, the lower end of the glass container's side wall bends inward to form a corner, connecting the side wall to the bent transverse wall. This corner is typically unshielded, yet objects may be placed there in practice. Because the corner is unshielded, objects placed there will still be exposed to the user due to the discontinuity of the existing shielding area, affecting the user experience and the overall aesthetic appeal of the container. Furthermore, the processing techniques for the longitudinal shielding film and the transverse wall shielding differ, or because the transverse wall shielding is generally circumferential while the longitudinal shielding film is non-circumferential, resulting in inconsistent shapes. This makes it difficult to use the same process to make them continuous. Additionally, the curved shape of the corner increases the complexity of positioning and other processing steps. Therefore, both directly extending the longitudinal shielding film and extending the transverse wall shielding as a whole increase the complexity of the tooling. Therefore, when there are objects that need to be covered at the corners of a glass container, how to ensure that the objects are completely covered without increasing the tooling complexity of the covering parts on the glass container has become a problem that needs to be solved in this field. Utility Model Content

[0004] This application provides a liquid heating container to solve the problem that, in order to ensure that the object is completely blocked when there is an object that needs to be blocked at the corner of the glass container, the prior art would significantly increase the tooling complexity of the blocking film on each part of the glass container.

[0005] The technical solution adopted in this application is as follows:

[0006] This application provides a liquid heating container, including a glass container body, a detection element, and a non-transparent adhesive. The glass container body includes a longitudinal sidewall, a transverse wall extending toward the center of the container body, and a corner connecting the longitudinal sidewall and the transverse wall. A first shielding film is covered on the longitudinal sidewall, and a second shielding film is covered on the transverse wall. The first shielding film and the second shielding film are spaced apart at the corner. One side of the adhesive covers the gap and is adhered to the glass container body, and the other side of the adhesive is adhered to the detection element.

[0007] Furthermore, the adhesive is a thermally conductive double-sided adhesive, one side of which is sequentially connected to the first shielding film, the spacer, and the second shielding film.

[0008] Furthermore, the upper end of the adhesive is adhered to the first shielding film, the lower end is adhered to the second shielding film, and a tensile force is formed on the area covered by the adhesive in the interval, so that the adhesive adheres to the outer wall of the corner in a non-adhesive manner.

[0009] Furthermore, the first shielding film is a vertical strip, the second shielding film is an annular surface or a plane extending radially, and the width of the adhesive is the same as the width of the first shielding film.

[0010] Furthermore, the detection element includes at least one of a water detection component and a temperature sensing component, wherein the water detection component and / or the temperature sensing component are adhered to the side of the adhesive member facing away from the glass container.

[0011] Furthermore, the detection element also includes a wire, and the water detection component and / or the temperature sensing component are connected to the coupler via the wire, which is adhered to the side of the adhesive member facing away from the glass container.

[0012] Furthermore, the liquid heating container also includes a heat insulation component, which is connected to an adhesive component located on the outer periphery of the temperature sensing component to form a heat insulation cavity. The temperature sensing component is placed in the heat insulation cavity, and the thermal conductivity of the heat insulation component is less than that of silicone rubber.

[0013] Furthermore, the insulation component is tightly attached to the temperature sensing component on the side facing the temperature sensing component.

[0014] Furthermore, the side of the insulation component facing the outer wall of the glass container is the first side, and the outer periphery of the first side is adhered to an adhesive component located on the outer periphery of the temperature sensing component, so that the first side deforms to fit the temperature sensing component.

[0015] Furthermore, the insulation component is EVA foam or rubber-plastic foam; or the thermal conductivity of the insulation component is less than 0.1 W / (m·K).

[0016] Compared with the prior art, the beneficial effects of this application are as follows:

[0017] This application provides a non-transparent adhesive at the gap between the first and second shielding films. One side of the adhesive can cover the gap at the corner and adhere to the glass container body, while the other side fixes the detection element to the glass container body by adhesion. This not only fixes the detection element but also shields the object located at the corner. Furthermore, it eliminates the need to add processing steps at the corner to extend the first or second shielding film, and can achieve sufficient shielding of the object at the corner without increasing the complexity of the tooling.

[0018] Furthermore, this application uses thermally conductive double-sided adhesive with a high thermal conductivity as the adhesive component to ensure the timeliness of the temperature measurement data of the detection element and avoid delays. Moreover, the thermally conductive double-sided adhesive is an integral adhesive structure, so that the first shielding film, the adhesive component, and the second shielding film are all adhered to the glass container body. This can further ensure the stability of the connection between the detection element and the glass container body and avoid any gaps that may exist between the first shielding film, the adhesive component, and the second shielding film, thereby improving the shielding effect.

Detailed Implementation

[0027] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0029] Furthermore, it should be understood in the description of this application that the terms "top," "bottom," "inner," "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0030] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0031] In this application, unless otherwise expressly specified and limited, the "above" or "below" of the second feature can mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. In the description of this specification, references to terms such as "implementation," "example," "a particular embodiment," "example," or "specific example," etc., indicate that the specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described can be combined in any suitable manner in one or more embodiments or examples.

[0032] Unless otherwise specified, the outer wall / outer wall surface in this application can be any outer wall surface of the glass container body, such as the outer wall surface of the side wall of the glass container body, the outer wall surface of the transverse wall extending from the lower end of the side wall towards the center of the container body, the outer wall surface of the corner connecting the side wall and the transverse wall, etc., or any outer wall surface of the glass container body covered with a shielding film. Among them, the transverse wall includes at least annular transverse walls and planar transverse walls; the detection element includes a temperature measuring element, a water measuring element, a wire, or a combination of two or three of them; the specific limitation, such as "the outer wall at the corner is usually not provided with a shielding film", refers to the outer wall surface at the corner of the glass container body and is in a transparent and unobstructed state.

[0033] To improve the shielding effect on glass containers, current research includes shielding of the container's sidewalls and the annular step below the sidewall's bend. However, it does not address shielding at the junction of the sidewall and the transverse wall, i.e., the corner. For liquid heating containers with corners at the lower end of the sidewalls, there is usually a gap between the shielding film on the longitudinal sidewall and the transverse shielding film extending towards the center of the container at the aforementioned corner. The outer glass wall at the corner is usually unshielded, which means that objects located on the outer wall at the corner (including the detection element itself) are exposed to the user's view, affecting the user experience and the overall aesthetics of the container. However, in practical applications, the longitudinal shielding film is usually screen-printed onto the longitudinal sidewalls of the glass container, while the shielding portion of the transverse wall is usually covered by lamination or electroplating onto the outer surface of the transverse wall. Due to the different processing techniques of the two shielding films, or because the shielding portion of the transverse wall is generally covered circumferentially while the longitudinal shielding film is not circumferentially covered, the shapes of the two shielding parts are inconsistent, making it difficult to use the same process to make them continuous. Extending the shielding increases processing costs, and the shape of the corner outer wall is curved. Whether it is screen printing, lamination, electroplating, or other processing methods, it will increase the processing steps such as positioning. Therefore, whether directly extending the longitudinal shielding film or extending the shielding portion of the transverse wall as a whole, it will significantly increase the complexity of the tooling.

[0034] To achieve adequate obscuring of objects at corners without increasing tooling complexity, and considering that the detection element itself needs to be fixed to the glass container via connectors, this application proposes using non-transparent adhesives. The size and position of the adhesive (e.g., the first adhesive) used to fix the detection element are adjusted so that one side covers the unobscurified corner gap and connects to the glass container to achieve adequate obscuring of the corner object, while the other side connects to the detection element to fix it. Since the entire side is adhesive, other objects can also be adhered and fixed. Thus, without adding components, this application achieves obscuring of corner objects simultaneously without increasing tooling complexity by reusing adhesives, improving the aesthetics of the glass container and the user experience.

[0035] The technical solution of this application will now be clearly and completely described with reference to the accompanying drawings.

[0036] In one embodiment, such as Figures 5-6 As shown, the liquid heating container includes a glass container body 100, a detection element, and a non-transparent adhesive 600. The glass container body 100 includes a longitudinal sidewall, a transverse wall extending toward the center of the container body, and a corner 1001 connecting the longitudinal sidewall and the transverse wall. A first shielding film 601 is covered on the longitudinal sidewall, and a second shielding film 602 is covered on the transverse wall. The first shielding film 601 and the second shielding film 602 are spaced apart at the corner 1001. One side of the adhesive 600 covers the gap and is bonded to the glass container body 100, and the other side of the adhesive 600 is bonded to the detection element.

[0037] The aforementioned solution involves providing a non-transparent adhesive 600 at the gap between the first shielding film 601 and the second shielding film 602. One side of the adhesive 600 covers the corner gap and adheres to the glass container body 100, while the other side fixes the detection element to the glass container body 100 via adhesion. This achieves both the fixation of the detection element and the shielding of objects located at the corner, without requiring additional processing steps at the corner to extend the first or second shielding film 601 or 602. It achieves sufficient shielding of objects at the corner without increasing tooling complexity, improving the overall craftsmanship and user experience of the glass container. Furthermore, the adhesive 600's overall adhesiveness also enables the fixation of objects at the corner.

[0038] The connection methods between the adhesive component 600 and the outer wall of the glass container body 100 include overall bonding and partial bonding.

[0039] In some embodiments, the adhesive 600 is a double-sided adhesive structure, which can be achieved using thermally conductive double-sided adhesive. Specifically, the side of the thermally conductive double-sided adhesive facing the container body sequentially connects the first shielding film 601, the spacer (located on the outer wall of the corner 1001), and the second shielding film 602 from top to bottom to achieve overall adhesion, while the other side is used to adhere and fix the detection element. The advantage of this embodiment is that by using thermally conductive double-sided adhesive with a high thermal conductivity as the adhesive 600, the timeliness of the temperature measurement data by the detection element is ensured, avoiding delays. Furthermore, the thermally conductive double-sided adhesive is an integral adhesive structure, allowing the first shielding film 601, the adhesive 600, and the second shielding film 602 to be continuously adhered to the glass container body 100, which further ensures the stability of the connection between the detection element and the glass container body 100 and avoids any gaps that may exist between the first shielding film 601, the adhesive 600, and the second shielding film 602, thereby improving the shielding effect.

[0040] In some embodiments, the adhesive 600 is partially double-sided, with the area covering the gap on its container-facing side not being adhesive. Specifically, the upper end of the adhesive 600 facing the container is adhered to the first shielding film 601, and the lower end is adhered to the second shielding film 602, creating a two-way tensile force on the area covered by the adhesive 600, so that the area covered by the adhesive 600 is tightly adhered to the outer wall of the corner 1001 in a non-adhesive manner. The other side of the adhesive 600 is fixed with the adhesion detection element.

[0041] In some other embodiments, depending on the location of the detection element, the upper edge of the adhesive 600 can be made to coincide with the lower edge of the first shielding film 601, or the lower edge can be made to coincide with the upper edge of the second shielding film 602, thereby saving processing costs while fixing and shielding the detection element.

[0042] In the aforementioned embodiments, whether it is overall adhesion or partial adhesion, when the side of the adhesive 600 facing away from the container body is generally adhesive, the detection element can be adhered to the side wall, corner 1001 and / or transverse wall of the glass container body 100 through the adhesive 600.

[0043] For example, the detection element can be a separate water detection component or a temperature sensing component, or a combination of both, with the water detection component and / or temperature sensing component adhered to the side of the adhesive 600 facing away from the glass container body 100. When both water detection and temperature sensing components are provided simultaneously, to further reduce tooling complexity, they are placed adjacent to each other, and the width of the adhesive 600 can simultaneously cover both the water detection component and the temperature sensing component. Furthermore, the detection element also includes a wire for connecting the temperature sensing component / water detection component to the bottom coupler / controller. In this case, the side of the adhesive 600 facing away from the container body can also be connected to the wire, fixing and blocking the wire located at the corner 1001 interval. Furthermore, when the liquid heating container also includes the aforementioned insulation component 102, the adhesive 600 can use a first adhesive 501, and the insulation component 102 is bonded to the first adhesive 501 located on the outer periphery of the temperature sensing component by a non-thermal conductive second adhesive to form an insulation cavity, thereby connecting it to the container body.

[0044] It should be noted that the transverse wall in the foregoing embodiments is defined as a wall surface extending toward the center of the container (or radially extending when the container is cylindrical), and the wall surface includes smooth planes, uneven planes, horizontal planes, and walls that are slightly inclined relative to the horizontal plane.

[0045] Furthermore, the first shielding film 601 is a vertical strip, and the second shielding film 602 is a radially extending annular surface or a plane. The width of the adhesive 600 is the same as the width of the first shielding film 601. Specifically, when the transverse wall extends towards the center of the container until it forms a plane, this transverse wall is the bottom of the container. In this case, the second shielding film 602 is a plane that can cover the entire bottom of the container to shield the structure of the bottom of the container. When the transverse wall extends towards the center of the container for a certain distance and then changes direction to continue extending downward, the transverse wall is an annular step. The second shielding film 602 is an annular surface that covers the outer wall of the annular step to shield the structure at the bottom of the corresponding gap of the annular step.

[0046] It should be noted that, Figure 6 The shown transverse wall is only one embodiment. In the figure, the transverse wall extends a certain distance towards the center of the container, then changes direction and continues to extend downward. After extending downward for a certain distance, it bends again to form a second corner, and then extends back towards the center of the container until it forms a flat surface. At this point, the transverse wall and all its extensions constitute the bottom of the container. Where the process allows, there can be multiple second corners formed by the bend, meaning it can be bent multiple times. The shape of the container bottom is not limited. In the aforementioned embodiment, the second shielding film 602 can cover the entire outer wall of the container bottom to shield the structure below the container. In other embodiments, the liquid heating container may not have a bottom surface. That is, the transverse wall extends a certain distance towards the center of the container, then changes direction and extends downward. After extending a certain distance, it can be assembled with components such as the heating plate, without needing to close to form a flat or other shaped container bottom. In this case, the second shielding film 602 can cover the outer wall of the transverse wall and its vertical extensions to shield the structure below the container.

[0047] In some embodiments, the first shielding film 601 is screen-printed onto the outer wall surface of the longitudinal sidewall, and / or the second shielding film 602 is electroplated or sprayed onto the outer wall surface of the transverse wall.

[0048] Furthermore, to improve the accuracy of liquid temperature measurement inside glass containers, existing technologies place silicone rubber or elastic thermally conductive elements between the temperature sensing element on the outer wall and the handle. The pressure from the silicone rubber or elastic thermally conductive elements presses the temperature sensing element against the outer wall of the container, thus fixing it in place. The internal liquid temperature is then obtained by measuring the temperature of the outer wall. Compared to the indirect method of measuring liquid temperature by placing the temperature sensing element at the bottom of the heating plate, this method, placing it on the outer wall, improves the accuracy of liquid temperature measurement to some extent. However, in temperature measurement of glass containers, thin-film thermistors (Negative Temperature Coefficient Thermistors) are typically used as the temperature sensing element to better conform to the outer wall of the container. Thin-film NTCs are double-sided temperature sensing elements, meaning that the measured temperature is affected by both the temperature of the outer wall and the external environment of the container. Therefore, when placing the temperature sensing element on the outer wall for liquid temperature measurement, existing technologies using elastic elements such as silicone rubber as pressing components to fix the temperature sensing element cannot avoid, and may even increase, the influence of the external environment on the temperature of the sensing element. For example, the thermal conductivity of ordinary silicone rubber is approximately 0.2–0.3 W / (m·K), and can reach over 10 W / (m·K) after filling. During prolonged use of liquid heating containers, even ordinary silicone rubber can cause the temperature of the NTC (Near-Temperature Collector) on the side facing away from the container's outer wall to be affected by the temperature of the external air. This means that the temperature measured by the NTC is actually the result of the combined effect of the outer wall temperature and the ambient temperature. Furthermore, elastic elements such as silicone rubber have poor thermal diffusion properties. When the temperature rise of the outer wall acts on the NTC, it also acts on the silicone rubber, causing the silicone rubber to heat up and be difficult to cool down. During continuous use of the liquid heating container, the temperature measured by the NTC will actually be the result of the combined effect of the outer wall temperature and the silicone rubber temperature. In addition, existing technologies that place a single-ended glass-sealed NTC on the bottom wall of the glass container use a heat insulation sleeve between the NTC temperature probe and the heating plate to reduce the interference of the heating plate's heat on the NTC temperature measurement. Although the solution takes into account the influence of the heating plate on temperature measurement, one end of the heat insulation sleeve will still be in direct contact with the heating plate and heat up. Moreover, the heat insulation sleeve is hollow and its size is larger than that of the NTC, making it difficult to form a relatively sealed space. Therefore, the NTC will still be affected by the temperature of the heat insulation sleeve itself and the external ambient temperature when measuring temperature.

[0049] To address the problems existing in the prior art, this application provides a temperature sensing component on the outer glass wall of the liquid heating container, while using an insulation component connected to the outer glass wall to form a relatively sealed insulation cavity. The temperature sensing component is placed in this insulation cavity. The insulation component itself heats up very slowly and can block heat transfer between the temperature sensing component and the external environment, so that the temperature measured by the temperature sensing component comes almost entirely from the outer glass wall and is not affected by the heat of the insulation component itself or the external environment.

[0050] In one embodiment, such as Figures 1-2As shown, the liquid heating container is a health pot, including a glass container body 100, a temperature sensing component 101, and a heat insulation component 102. The temperature sensing component 101 is attached to the outer wall of the container body, and the heat insulation component 102 is connected to the outer wall of the container body located on the periphery of the temperature sensing component 101 to form a heat insulation cavity. The temperature sensing component 101 is placed in the heat insulation cavity, and the thermal conductivity of the heat insulation component 102 is less than that of ordinary silicone rubber.

[0051] Preferably, the insulation component 102 can be EVA (Ethylene vinyl acetate) foam, rubber-plastic foam, PE (Polyethylene) foam, or glass wool; or the thermal conductivity of the insulation component 102 is less than 0.1 W / (m·K). For example, the insulation component 102 uses rubber-plastic foam (environmentally friendly), with a thermal conductivity of 0.03–0.05 W / (m·K), far less than that of ordinary silicone rubber (0.2–0.3 W / (m·K). Due to its extremely low thermal conductivity, when forming an insulation cavity with the outer wall of the container surrounding the temperature sensing component 101, the insulation component 102 can both block heat transfer from the temperature sensing component 101 to the outside of the insulation cavity and block heat transfer from the external environment to the temperature sensing component 101. Furthermore, the rubber-plastic foam itself has a lower heat accumulation capacity than silicone foam, resulting in a smaller temperature rise within the same time period. Therefore, it can further ensure that the temperature measurement of the temperature sensing component 101 is not affected, improving the accuracy of temperature measurement.

[0052] Furthermore, the insulation component 102 must also possess the characteristic of not absorbing water. Since steam is easily generated during the use of the liquid heater, if the insulation component 102 (e.g., glass wool) has good water absorption, it can easily damage the temperature sensing component 101, shorten its service life, and affect the detection accuracy. Of course, those skilled in the art will understand that a water-blocking structure, such as a silicone part or a shielding part 103, can be provided around the insulation component 102 to achieve a sealed and waterproof effect.

[0053] Furthermore, the health-preserving kettle also includes a shielding component 103, which covers the heat-insulating component 102 and is connected to the outer wall of the container. Of course, those skilled in the art will understand that the heat-insulating component 102 in the above technical solution can also be exposed without the shielding component 103. In this embodiment, the shielding component 103 is the handle of the health-preserving kettle. One end of the handle is connected to the upper end of the glass container body 100, and the other end is connected to the base of the health-preserving kettle. Its side facing the container body can completely cover the temperature-sensing component 101 and the heat-insulating component 102 located on the outer wall of the container, while providing a grip function, combining practicality and aesthetics. In some other embodiments, the position of the handle is adapted to the position of the temperature-sensing component 101 on the outer wall of the container, for example, located in the upper half of the outer wall of the container; the shielding component 103 can also be other added components, such as a shielding piece adapted to the shape of the heat-insulating component 102, specifically used to cover the heat-insulating component 102. In some other embodiments, such as... Figure 3As shown, the health pot also includes a water detection component 104, which is located on one side of the temperature sensing component 101 and is attached to the outer wall of the container.

[0054] In this embodiment, the insulation component 102 has extremely poor thermal conductivity, which can effectively reduce the heat conduction between the temperature sensing component 101 and the environment on the side away from the outer wall of the container, blocking the external environment from transferring heat to the temperature sensing component 101 and avoiding the influence of the external environment on the temperature measurement of the temperature sensing component. On the other hand, the insulation component 102 can prevent heat from spreading outward, and its own temperature change is smaller than that of existing silicone components. That is, the temperature of the insulation component 102 itself is not easily affected by the temperature rise of the outer wall of the glass, and has less impact on the subsequent temperature measurement of the temperature sensing component 101. As a result, the temperature data measured by the temperature sensing component 101 comes almost entirely from the outer wall of the glass container 100, improving the accuracy of measuring the internal liquid temperature of the container by the temperature of the outer wall.

[0055] It should be noted that the temperature sensing component 101 can be a thin-film NTC component, which uses two insulating films to clamp the NTC sensor and the wires used to connect the sensor and the coupler between them. Therefore, when the temperature sensing component 101 is attached to the outer wall of the container, the shape of the flexible insulating film can fit tightly against the outer wall of the container, ensuring the accuracy of the temperature measurement on the outer wall.

[0056] Furthermore, such as Figure 4 As shown, the insulation component 102 is tightly attached to the temperature sensing component 101 on the side facing it. This tight contact means there are no gaps between the insulation component 102 and the temperature sensing component 101, theoretically eliminating gaps in the insulation cavity 1021 and further improving the insulation effect. In other embodiments, there may be extremely small gaps between the insulation component 102 and the temperature sensing component 101 to ensure the best possible insulation effect.

[0057] In some embodiments, the side of the insulation member 102 facing the outer wall of the container is a first side 1022, and the outer periphery of the first side 1022 is adhered to the outer wall of the container located on the outer periphery of the temperature sensing component 101, so that the first side 1022 deforms to fit the temperature sensing component 101. Figure 4This is a cross-sectional view showing the adhesion of the outer wall of the container, the temperature sensing component 101, and the insulation component 102. The shaded area represents the insulation cavity 1021 formed by the connection between the insulation component 102 and the outer wall of the container. The outer periphery of the first surface 1022 of the insulation cavity 1021 is adhered to the outer wall of the container, forming a regular or irregular ring at the adhesion point. The inner curve shape of this ring matches the outer edge shape of the temperature sensing component 101 for better fit. The junction between the adhesion point and the part attached to the temperature sensing component (part A in the figure) undergoes slight deformation, allowing the first surface 1022 to tightly adhere to all other surfaces of the temperature sensing component that are not attached to the outer wall of the container. This ensures that there are almost no gaps between the temperature sensing component 101 and the insulation component 102, thereby ensuring good insulation performance. At the same time, the junction applies a certain pressure to the temperature sensing component 101, making the temperature sensing component 101 (especially the soft temperature sensing component) adhere more firmly to the outer wall of the container. Based on this, the insulation component 102 is bonded to the temperature sensing component 101 in an adhesive manner. That is, while the outer periphery of the first surface 1022 is bonded to the outer wall of the container, the remaining part of the first surface 1022 is bonded to all other surfaces of the temperature sensing component 101 that are not bonded to the outer wall of the container, thereby further reducing the gap between the two and improving the insulation effect.

[0058] In some embodiments, the outer wall of the container is covered with a shielding film to shield the temperature sensing component 101 and / or the insulation component 102, thereby improving the aesthetics of the glass container and the user experience. In this case, the outer periphery of the first surface 1022 is adhered to the shielding film located on the outer periphery of the temperature sensing component 101, so that the insulation component 102 is indirectly connected to the container body.

[0059] It should be noted that the first surface 1022 can be a flat surface or an irregular surface to adapt to the shape of the temperature sensing component 101. The first surface 1022 can be a flexible material, and its area must be large enough to cover all surfaces of the temperature sensing component 101 that are not attached to the outer wall of the container. Using a flexible material allows for better fit to irregular curved surfaces and reduces the likelihood of springback, resulting in a more secure connection. In some embodiments, the first surface 1022 may also remain unchanged, simply covering the temperature sensing component 101 with its sufficiently large area to provide wrapping and insulation.

[0060] Furthermore, the temperature sensing component 101 is bonded to the outer wall of the container body using a first adhesive, and the insulation component 102 is connected to the outer wall of the container body located around the temperature sensing component using a second adhesive. The thermal conductivity of the first adhesive is greater than that of the second adhesive. Figure 2As shown, one side of the first adhesive adheres to and covers the side of the temperature sensing component 101 facing the outer wall of the container, or it may be slightly smaller than this side. The other side is adhered to the outer wall of the container, so that the temperature sensing component 101 is fixed to the outer wall of the container. Since the side of the temperature sensing component 101 facing the outer wall is the direct source for measuring the temperature of the outer wall, the first adhesive used for connection needs to have good thermal conductivity to reduce the delay in temperature measurement. Therefore, an adhesive material with a high thermal conductivity, such as thermally conductive double-sided tape, should be used.

[0061] The second adhesive adheres to and covers one side of the insulation component 102 facing the outer wall of the container, where it contacts the outer periphery (in this case, the second adhesive is in the form of a regular or irregular ring), or covers the entire surface of the insulation component 102 facing the outer wall of the container, while the other side is directly or indirectly connected to the outer wall of the container, so that the insulation component 102 is fixed to the outer wall of the container and forms an insulation cavity. Since the insulation cavity needs to be insulated, the second adhesive must also have the same properties; its thermal conductivity needs to be sufficiently low, at least less than that of the first adhesive, to prevent the temperature of the outer wall from being transferred to the insulation component 102 and affecting the accuracy of continuous temperature measurement.

[0062] In this embodiment, a first adhesive with a high thermal conductivity is used to bond the temperature sensing component, and a second adhesive with a low or almost non-thermal conductivity is used to bond the insulation component 102. This ensures that the internal temperature of the liquid is quickly transferred to the temperature sensing component 101, reducing delay, and also prevents the insulation component 102 from absorbing heat and affecting the accuracy of continuous temperature measurement.

[0063] In some embodiments, the second adhesive is bonded to the first adhesive 501 to connect the insulation element 102 to the outer wall of the container. For example... Figure 5 As shown, the area of ​​the first adhesive 501 is larger than the area of ​​the side of the insulation component 102 facing the outer wall of the container, so that while fixing the temperature sensing component 101 to the outer wall of the container, other components, such as the water detection component, are also fixed to the outer wall of the container. Specifically, one side of the first adhesive 501 is adhered to the outer wall of the container, and the other side is directly adhered to the temperature sensing component 101 and the water detection component 104, which can simultaneously cover the temperature sensing component 101, the insulation component 102, and the water detection component 104. At this time, the insulation component 102 is indirectly connected to the outer wall of the container through the first adhesive 501 and the second adhesive. Specifically, the outer periphery of the first surface 1022 of the insulation component 102 is adhered to the first adhesive 501 located on the outer periphery of the temperature sensing component 101 through the second adhesive, so that the first surface 1022 deforms and fits the temperature sensing component 101.

[0064] In some embodiments, the temperature sensing component 101 is adhered to the outer wall of the container, and / or the insulation component 102 includes an insulation layer and an adhesive layer, the adhesive layer being used to connect the insulation layer to the outer wall of the container located on the periphery of the temperature sensing component. In this embodiment, the side of the insulation component 102 facing the outer wall of the container has its own adhesive layer, allowing the insulation component to be directly adhered to the outer wall of the container located on the periphery of the temperature sensing component 101, or to be connected to the outer wall of the container by adhering to the first adhesive 501 in the aforementioned embodiments. The adhesive layer can be made of the same material as the second adhesive in the aforementioned embodiments, ensuring the insulation effect of the insulation cavity. The built-in adhesive layer allows for a wider range of applications for the insulation component 102.

[0065] It should be noted that the fixed positions of the temperature sensing component 101, water detection component 104 and other detection elements in the foregoing embodiments are not limited to the outer wall at the lower end of the side wall of the glass container 100 shown in the figure in actual applications. They can also be set on the outer wall at other positions of the side wall or on other outer wall surfaces of the glass container 100, such as the outer wall surface of the transverse wall extending toward the center of the container.

[0066] The liquid heating container in this application can also be a soymilk maker or other heaters with a glass container body. The shape of the glass container body is not limited; it can be cylindrical, square, or other shapes. The glass container body can be an all-glass container body, or it can be a glass kettle body with openings at the top and bottom combined with a heating plate.
