Description

Technical Field

[0001] This application relates to the field of household appliances, and more particularly to a liquid heating container. Background Technology

[0002] Liquid heating containers typically consist of a container body and a lid. The lid has a venting channel, allowing steam inside the container to escape and reduce internal pressure. However, if the venting channel is always open, the temperature inside the container will drop too quickly, affecting the heating rate of the liquid heating container. Utility Model Content

[0003] This application provides a liquid heating container that can solve the problem of low heating efficiency in existing liquid heating containers.

[0004] This application provides a liquid heating container, comprising: a container body having an inner cavity; a container lid including a lid body and a baffle, the lid body having an air inlet channel and an air outlet channel, the outlet of the air inlet channel communicating with the air outlet channel; a sealing assembly including a bracket and a sealing member, the bracket being fixedly installed on the lid body and forming a first accommodating space with the lid body, the first accommodating space communicating with the inner cavity and the inlet of the air inlet channel respectively, the sealing member being movably installed within the first accommodating space; when the liquid heating container is tilted, the sealing member can move within the first accommodating space to close the inlet of the air inlet channel; the baffle is located at the outlet of the air inlet channel and is movably installed on the bracket, the baffle being used to open the outlet of the air inlet channel when the gas pressure in the air inlet channel is greater than a preset value; the baffle is also used to close the outlet of the air inlet channel when the gas pressure in the air inlet channel is less than or equal to the preset value.

[0005] In the above scheme, the steam generated by heating the liquid in the inner cavity can flow to the outside through the inlet and outlet channels to achieve the effect of venting and depressurizing, avoiding excessive pressure in the inner cavity and potential safety hazards. A baffle is movably installed at the outlet of the inlet channel. When the steam pressure in the inlet channel is less than or equal to a preset value, the baffle can close the outlet of the inlet channel under gravity, preventing steam in the inner cavity from flowing to the outlet channel, thereby reducing the amount of steam discharged and preventing the temperature in the inner cavity from dropping too quickly, which is beneficial to improving the heating rate and heat preservation effect of the liquid heating container. When the steam pressure in the inlet channel is greater than the preset value, the baffle can move relative to the cover under the action of steam pressure to open the outlet of the inlet channel, allowing steam in the inner cavity to flow to the outlet channel for rapid depressurization and venting, improving the safety of the liquid heating container. Under normal conditions, the sealing component moves away from the inlet of the inlet channel under gravity, opening the inlet of the inlet channel and allowing steam in the inner cavity to flow to the outlet channel. When the liquid heating container is tilted (either when a user pours water or when the container is accidentally tilted), the sealing component moves within the first accommodating space under gravity to close the inlet of the air intake channel, thereby preventing liquid in the inner cavity from flowing through the air intake channel to the exhaust channel. Therefore, by incorporating the sealing component, the liquid heating container can be prevented from tipping over, reducing the risk of liquid leaking out through the air intake and exhaust channels when the container is tilted. When the baffle is mounted on the bracket, it is integrated with the sealing component, which not only saves parts and makes efficient use of the space within the cover, but also improves the installation accuracy of the baffle, ensuring it precisely covers the air intake channel, thus enhancing its reliability.

[0006] In one possible design, the bracket is provided with a mounting portion, and the cover is provided with a mounting hole corresponding to the mounting portion; at least a portion of the mounting portion passes through the mounting hole and is movably connected to the baffle.

[0007] In the above solution, at least a portion of the mounting part passes through the mounting hole and is movably connected to the baffle, facilitating the installation of the baffle and improving the assembly efficiency of the container lid. Furthermore, the mounting hole also provides a limiting effect on the mounting part, enhancing the installation stability of the bracket.

[0008] In one possible design, the baffle includes a rotating shaft that is rotatably connected to the mounting portion.

[0009] In the above scheme, the baffle and the bracket are rotatably connected by a rotating shaft and a mounting part. When the gas pressure in the air intake channel is greater than a preset value, the baffle can rotate to open the outlet of the air intake channel under the action of the gas pressure; when the gas pressure in the air intake channel is less than the preset value, the baffle can rotate to close the outlet of the air intake channel under the action of gravity.

[0010] In one possible design, the baffle is provided with a limiting rib, which is used to abut against the cover during the rotation of the baffle relative to the mounting part.

[0011] In the above scheme, the limiting rib can limit the rotation angle of the baffle, preventing the baffle from failing to reset itself due to excessive rotation angle. This ensures that the baffle can automatically close the outlet of the intake channel under the action of gravity when the gas pressure in the intake channel is less than or equal to the preset value, thus improving the reliability of the baffle.

[0012] In one possible design, an abutment protrusion is provided at the outlet of the air intake channel, and the baffle can abut against the abutment protrusion when closing the outlet of the air intake channel.

[0013] In the above design, the baffle can engage with the abutting protrusion to limit its rotation angle, facilitating its upward rotation under steam pressure and further improving its reliability. Furthermore, when the baffle closes the outlet of the air inlet channel, it remains horizontal under the support of the abutting protrusion, enhancing its stability.

[0014] In one possible design, the sealing element includes a first part, which is a frustum structure; the support includes a support body, which is used to form the first receiving space with the cover, and the inner sidewall of the support body is provided with an inclined surface, so that when the liquid heating container is tilted, the sidewall of the first part can slide with the inclined surface.

[0015] In the above scheme, when the liquid heating container is tilted, the side wall of the first part can slide and engage with the inclined surface to increase the moving speed of the sealing component, thereby enabling the sealing component to quickly close the air intake channel.

[0016] In one possible design, the container lid further includes a partition, which is fixedly connected to the lid body; the partition and the lid body form a steam cavity, which is connected to the outlet of the air inlet channel and the exhaust channel respectively, and the baffle is located in the steam cavity.

[0017] In the above solution, by setting a baffle, steam can be prevented from flowing towards the water outlet button, thereby reducing the risk of steam flowing out from the top of the container lid and scalding the user, and improving the sealing performance of the exhaust structure.

[0018] In one possible design, the container lid further includes a sealing ring, which is clamped between the partition and the lid body along the height direction of the container lid.

[0019] In the above scheme, setting a sealing ring helps to improve the sealing effect between the partition and the cover, thereby further improving the sealing performance of the exhaust structure.

[0020] In one possible design, the cover is also provided with a pressure relief hole, which is connected to the inner cavity and the exhaust channel respectively.

[0021] In the above solution, the pressure relief hole can continuously release pressure and exhaust air to avoid the safety hazard caused by the inability of steam in the inner cavity to be discharged when the air intake channel is closed, thus improving the user experience.

[0022] In one possible design, the container body includes a fixedly connected main body and a bottom cover, with a steam pipe installed inside the main body, the two ends of which are respectively connected to the exhaust channel and the bottom cover.

[0023] In the above solution, the two ends of the steam pipe are connected to the exhaust channel and the bottom cover, respectively. The steam in the exhaust channel can flow to the bottom cover through the steam pipe and then to the outside through the bottom cover, thus preventing the steam from flowing out from the top of the container and scalding the user.

[0085] The accompanying drawings, which are incorporated in and form part of this specification, illustrate embodiments consistent with this application and, together with the description, serve to explain the principles of this application. Detailed Implementation

[0086] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0087] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0088] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0089] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0090] It should be noted that the directional terms such as "upper," "lower," "left," and "right" described in the embodiments of this application are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when it is mentioned that an element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.

[0091] This application provides a liquid heating container, such as... Figure 1 As shown, the liquid heating container includes a container body 1, a container lid 2, and a base 3. The container body 1 includes a main body 12 and a bottom cover 13 fixedly connected. The main body 12 has an inner cavity 11 for holding liquid, and a heating element 15 is disposed within the space enclosed by the main body 12 and the bottom cover 13. When the container body 1 is placed on the base 3, the base 3 supplies power to the heating element 15 to heat the liquid in the inner cavity 11, thus realizing the heating function of the liquid heating container. The container lid 2 is fastened to the container body 1 and has a water outlet structure. The main body 12 has a water outlet 124, and the liquid in the inner cavity 11 is discharged outward from the water outlet 124 through the water outlet structure, thus realizing the water discharge function of the liquid heating container. In addition, the container body 1 also has a handle 16 fixedly connected to the main body 12, which allows the user to hold or move the liquid heating container, making it more convenient to use.

[0092] The following describes the water outlet structure of container lid 2, such as... Figure 2As shown, the container lid 2 includes a lid body 21, on which a water outlet 214 and a water outlet channel 215 are provided. A water outlet valve 27 is also provided at the water outlet 214, which is used to open or close the water outlet 214. Figure 3 As shown, when the outlet valve 27 opens the outlet hole 214, the liquid in the inner cavity 11 can flow through the outlet hole 214 to the outlet channel 215, and thus flow out through the outlet spout 124; when the outlet valve 27 closes the outlet hole 214, the outlet valve 27 can prevent the liquid in the inner cavity 11 from flowing to the outlet channel 215. The container cover 2 also includes a water outlet button 28, which is rotatably mounted inside the cover body 21. The water outlet button 28 has a pressing part 281 and a driving part 282. At least a portion of the pressing part 281 is exposed outside the cover body 21, and the end of the water outlet valve 27 away from the outlet hole 214 is slidably mounted on the driving part 282. Figure 3 As shown, when water needs to be poured out, the user can press down on the pressing part 281 so that the driving part 282 can drive the water outlet valve 27 away from the water outlet 214, thereby opening the water outlet 214. Figure 2 As shown, a return spring 283 is installed on the drive unit 282. The two ends of the return spring 283 abut against the drive unit 282 and the cover 21, respectively. During the upward movement of the drive unit 282 and the pressing part 281, the return spring 283 is in a compressed state. Therefore, when the water is poured out, the user only needs to stop pressing the pressing part 281, and the drive unit 282 will reset under the restoring force of the return spring 283, thereby driving the water outlet valve 27 to move closer to the water outlet hole 214 to close the water outlet hole 214. Therefore, by setting the water outlet valve 27 and the water outlet button 28, the water outlet of the liquid heating container can be controlled, preventing the high-temperature liquid in the inner cavity 11 from flowing directly out of the water outlet 124 and causing leakage when the liquid heating container is accidentally tilted, thus improving the safety of the liquid heating container.

[0093] The container lid 2 is also equipped with a venting structure, such as... Figure 2 As shown, the cover 21 is provided with an air inlet channel 211 and an exhaust channel 212. The air inlet channel 211 is connected to the inner cavity 11 and the exhaust channel 212, respectively, while the exhaust channel 212 is used to connect to the outside. The steam generated by heating the liquid in the inner cavity 11 can flow to the outside through the air inlet channel 211 and the exhaust channel 212 to achieve the effect of venting and depressurizing, preventing excessive pressure in the inner cavity 11 and thus avoiding safety hazards. Figure 4As shown, the container lid 2 also includes a baffle 22, which is movably installed at the outlet of the air inlet channel 211. When the steam pressure in the air inlet channel 211 is less than or equal to a preset value, the baffle 22 can close the outlet of the air inlet channel 211 under the action of gravity, thereby preventing steam in the inner cavity 11 from flowing to the exhaust channel 212 through the air inlet channel 211, thus reducing the amount of steam discharged, so as to avoid the temperature in the inner cavity 11 dropping too quickly, which is beneficial to improving the heating rate and heat preservation effect of the liquid heating container. Figure 5 As shown, when the steam pressure in the air inlet channel 211 is greater than the preset value, the baffle 22 can move relative to the cover 21 under the action of steam pressure to open the outlet of the air inlet channel 211. The steam in the inner cavity 11 can flow to the exhaust channel 212 through the air inlet channel 211 to achieve rapid pressure relief and exhaust, thereby improving the safety of the liquid heating container.

[0094] It should be noted that the preset steam pressure refers to the safe pressure value of the liquid heating container during use. This preset value can be adjusted as needed, and this embodiment does not limit the specific value of the preset value. Specifically, the preset value can be adjusted by replacing the baffle 22 with one of different materials or weights, and this embodiment does not limit the adjustment method.

[0095] In this embodiment, the baffle 22 can be slidably or rotatably connected to the cover 21, or slidably or rotatably connected to the bracket 231. This embodiment takes the rotatable connection between the baffle 22 and the bracket 231 as an example to describe the installation structure of the baffle 22 in detail.

[0096] In one specific implementation, such as Figure 4 As shown, the baffle 22 includes a baffle body 223, a limiting rib 221, and a rotating shaft 222. The baffle body 223 is used to open or close the outlet of the air intake channel 211, and the rotating shaft 222 is used to realize the rotatable connection between the baffle 22 and the bracket 231. Figure 5 As shown, the limiting rib 221 is used to abut against the cover 21 during the rotation of the baffle 22 relative to the bracket 231, so as to limit the rotation angle of the baffle 22 and prevent the baffle 22 from failing to reset itself due to excessive rotation angle. This ensures that the baffle 22 can automatically close the outlet of the air intake channel 211 under the action of gravity when the gas pressure in the air intake channel 211 is less than or equal to the preset value, thereby improving the reliability of the baffle 22.

[0097] In one specific implementation, such as Figure 4As shown, an abutment protrusion 213 is provided at the outlet of the air intake passage 211. When the baffle 22 closes the outlet of the air intake passage 211, the baffle body 223 can abut against the abutment protrusion 213 to limit the rotation angle of the baffle 22, making it easier for the baffle 22 to flip upward under the action of steam pressure, thereby further improving the reliability of the baffle 22. Moreover, when the baffle 22 closes the outlet of the air intake passage 211, the baffle body 223 can be in a horizontal state under the support of the abutment protrusion 213, which helps to improve the stability of the baffle 22.

[0098] Specifically, the abutting protrusion 213 can be a ring structure arranged around the circumference of the air intake channel 211, or it can be multiple split structures arranged at intervals around the circumference of the air intake channel 211. This application embodiment does not limit this.

[0099] In one specific implementation, combined with Figure 2 and Figure 6 As shown, the container lid 2 also includes a partition 24, which is fixedly connected to the lid body 21. The partition 24 and the lid body 21 form a steam chamber 241, which is connected to the outlet of the air inlet channel 211 and the exhaust channel 212, respectively. A baffle 22 is located inside the steam chamber 241. By setting the partition 24, steam can be prevented from flowing towards the water outlet button 28, thereby reducing the risk of steam flowing out from the top of the container lid 2 and scalding the user, and improving the sealing performance of the exhaust structure.

[0100] like Figure 6 As shown, in this embodiment, the water dispensing button 28 can be rotatably mounted on the partition 24 to reduce the number of parts and thus reduce the volume of the container lid 2.

[0101] Combination Figure 2 and Figure 7 As shown, the container lid 2 also includes a sealing ring 25. Along the height direction of the container lid 2, the sealing ring 25 is sandwiched between the partition 24 and the lid body 21. The sealing ring 25 helps to improve the sealing effect between the partition 24 and the lid body 21, thereby further improving the sealing performance of the exhaust structure. Specifically, as... Figure 7 As shown, a mounting groove 216 can be provided on the cover 21, and at least a portion of the sealing ring 25 is accommodated in the mounting groove 216, which can improve the installation stability of the sealing ring 25 and thus help improve the reliability of the sealing ring 25.

[0102] In one specific implementation, such as Figure 2 As shown, the container lid 2 also includes a sealing assembly 23, which is installed on the lid body 21. Under normal conditions, the sealing assembly 23 is used to open the inlet of the air intake passage 211, allowing steam in the inner cavity 11 to flow through the air intake passage 211 to the exhaust passage 212. Figure 3As shown, when the liquid heating container is tilted (when the user pours water or when the liquid heating container is accidentally tilted), the sealing component 23 is used to close the inlet of the air inlet channel 211 to prevent the liquid in the inner cavity 11 from flowing to the exhaust channel 212 through the air inlet channel 211. Therefore, by setting the sealing component 23, the anti-tipping function of the liquid heating container can be realized, reducing the risk of liquid in the inner cavity 11 leaking out through the air inlet channel 211 and the exhaust channel 212 when the liquid heating container is tilted.

[0103] In one specific implementation, such as Figure 2 As shown, the sealing assembly 23 includes a bracket 231 and a sealing element 232. The bracket 231 is fixedly installed on the cover 21, and the bracket 231 and the cover 21 form a first receiving space 233. The first receiving space 233 is connected to the inlet of the inner cavity 11 and the air intake channel 211, respectively. The sealing element 232 is movably installed in the first receiving space 233. Under normal conditions, the sealing element 232 is moved away from the air intake channel 211 by gravity, so that the inlet of the air intake channel 211 is in the open state, and the steam in the inner cavity 11 can flow to the exhaust channel 212 through the first receiving space 233 and the air intake channel 211. Figure 3 As shown, when the liquid heating container tilts, the sealing element 232 can move relative to the support 231 under the action of gravity within the first receiving space 233, thereby closing the entrance to the air intake channel 211. By setting the structure in which the support 231 and the sealing element 232 cooperate, there is no need to set a separate control device. The sealing element 232 can open or close the air intake channel 211 under the action of gravity alone, which simplifies the structure of the sealing assembly 23 and makes it more convenient for users to operate.

[0104] In one specific implementation, combined with Figure 4 and Figure 8 As shown, the bracket 231 includes a mounting part 231a, a fixing post 231b, and a bracket body 231c. The fixing post 231b is fixedly connected to the cover 21 so that the bracket body 231c and the cover 21 can form a first receiving space 233. Furthermore... Figure 9As shown, the cover 21 is provided with a mounting hole 217 corresponding to the mounting part 231a. At least a portion of the mounting part 231a passes through the mounting hole 217 and is rotatably connected to the rotating shaft 222, so that the baffle 22 and the bracket 231 form a rotatable connection, which helps to improve the connection stability between the cover 21, the baffle 22, and the bracket 231. Moreover, by mounting the baffle 22 on the bracket 231, the baffle 22 and the sealing assembly 23 can be integrated together, which not only saves parts and makes reasonable use of the space inside the cover 21, but also helps to improve the installation accuracy of the baffle 22, ensuring that the baffle body 223 can accurately cover the outlet of the air intake channel 211, thereby improving the reliability of the baffle 22. In addition, the mounting hole 217 can also limit the mounting part 231a, which helps to improve the installation stability of the bracket 231.

[0105] In one specific implementation, such as Figure 8 As shown, the sealing component 232 includes a first part 232a and a second part 232b that are fixedly connected. The first part 232a has a frustum structure. The inner wall of the support body 231c is provided with an inclined surface 231ca. When the liquid heating container is tilted, the side wall of the first part 232a can slide against the inclined surface 231ca to increase the moving speed of the sealing component 232, thereby enabling the sealing component 232 to quickly close the air intake channel 211. The second part 232b has a cylindrical structure, which is convenient for handling and installation. Moreover, the cylindrical structure has a larger surface area, which is beneficial to improving the sealing effect of the sealing component 232.

[0106] Combination Figure 4 and Figure 8 As shown, the bracket 231 also includes an air inlet pipe 231d fixedly connected to the bracket body 231c, and the first accommodating space 233 communicates with the inner cavity 11 through the air inlet pipe 231d. In normal operation, at least a portion of the first part 232a is accommodated within the air inlet pipe 231d, which improves the stability of the sealing member 232 and increases the capacity of the first accommodating space 233, facilitating rapid steam discharge. Specifically, in normal operation, there is a certain gap between the sealing member 232 and the air inlet pipe 231d, allowing steam in the inner cavity 11 to flow into the first accommodating space 233 through this gap and then flow to the exhaust channel 212 via the air inlet channel 211.

[0107] like Figure 8 As shown, the side wall of the support body 231c can also be provided with a hollow portion 231cb. The first receiving space 233 is connected to the inner cavity 11 through the hollow portion 231cb, which is beneficial to improving the steam discharge efficiency. The number of hollow portions 231cb can be one or more, and this embodiment does not limit this.

[0108] In this embodiment, the intake pipe 231d and the perforated portion 231cb can be optionally provided, or both can be provided simultaneously. When both exist simultaneously, it is beneficial to further improve the steam discharge efficiency. The perforated portion 231cb can ensure smooth steam discharge when the intake pipe 231d is blocked.

[0109] In one specific implementation, such as Figure 2 and Figure 3 As shown, the container lid 2 also includes a base plate 29, which is fixedly installed on the lid body 21. The base plate 29 has multiple water passage holes 291. Liquid in the inner cavity 11 flows through the water passage holes 291 to the water outlet hole 214, meaning the base plate 29 has a filtering function, which improves the user experience. The base plate 29 and the lid body 21 form a second receiving space 292, and the sealing assembly 23 is located within the second receiving space 292. Figure 4 As shown, the base plate 29 is also provided with a through hole 293. At least part of the air intake pipe 231d extends into the inner cavity 11 through the through hole 293. At this time, the base plate 29 can limit the air intake pipe 231d, which is conducive to improving the installation stability of the bracket body 231, thereby improving the reliability of the sealing component 23.

[0110] The base plate 29 can be made of stainless steel, which has the advantages of high structural strength and easy cleaning.

[0111] In this embodiment, the steam in the inner cavity 11 can also enter the second accommodating space 292 through the water passage 291, and then enter the first accommodating space 233 through the hollow part 231cb, which increases the steam discharge path and helps to improve the steam discharge efficiency.

[0112] In one specific implementation, such as Figure 2 As shown, the cover 21 is also provided with a pressure relief hole 26, which is connected to the inner cavity 11 and the exhaust channel 212 respectively. The steam generated by heating the liquid in the inner cavity 11 can also flow through the pressure relief hole 26 to the exhaust channel 212, thereby flowing to the outside to achieve exhaust. Figure 3 As shown, when the liquid heating container is tilted, the sealing component 23 does not block the pressure relief hole 26, meaning the pressure relief hole 26 can continuously release pressure and exhaust air. This prevents the steam in the inner cavity 11 from being unable to escape when the air intake channel 211 is closed, thus avoiding potential safety hazards and improving the user experience. The number of pressure relief holes 26 can be one or more; this embodiment does not limit this.

[0113] It should be noted that the diameter of the pressure relief hole 26 is small. When the liquid heating container is tilted, the risk of liquid in the inner cavity 11 flowing to the exhaust channel 212 through the pressure relief hole 26 is small. Even if a small amount of liquid flows to the exhaust channel 212 through the pressure relief hole 26, it still meets the safety standards for liquid heating containers and will not cause any safety hazards.

[0114] In another embodiment, the pressure relief hole 26 may not be connected to the inner cavity 11 through the first receiving space 233, but may be directly connected to the inner cavity 11.

[0115] In summary, under normal conditions, the small amount of steam in the inner cavity 11 of the liquid heating container provided in this embodiment can flow directly to the exhaust channel 212 through the pressure relief hole 26. When there is a large amount of steam in the inner cavity 11, the steam pressure can push up the baffle 22, thereby venting steam to the exhaust channel 212 simultaneously through the air inlet channel 211 and the pressure relief hole 26. When the liquid heating container is tilted, the inlet of the air inlet channel 211 is closed by the sealing component 23, and the steam in the inner cavity 11 can flow to the exhaust channel 212 through the pressure relief hole 26. That is, the liquid heating container provided in this embodiment can combine the advantages of no leakage when tilted, high heating efficiency, and fast pressure relief rate.

[0116] In one specific implementation, such as Figure 1 As shown, a steam pipe 14 is installed inside the main body 12. The two ends of the steam pipe 14 are connected to the exhaust channel 212 and the bottom cover 13, respectively. The steam in the exhaust channel 212 can flow through the steam pipe 14 to the bottom cover 13 and then to the outside through the bottom cover 13, preventing steam from flowing out from the top of the container body 1 and scalding the user. Moreover, the steam does not pass through the handle 16 during its flow through the steam pipe 14, thus preventing the handle 16 from being affected by the temperature of the steam pipe 14 and causing an increase in temperature, thereby improving the user's convenience and comfort.

[0117] The steam pipe 14 can be made of metal or plastic, and can be a straight pipe or a bent pipe, or of other shapes. The specific design can be made according to actual needs and is not limited here.

[0118] like Figure 1 As shown, a thermostat 131 and a switch assembly 132 are provided inside the bottom cover 13. When steam from the steam pipe 14 flows into the bottom cover 13, the thermostat 131 can detect the temperature of the steam discharged from the steam pipe 14. When the temperature is greater than or equal to a preset value (generally 100°C), the thermostat 131 can control the switch assembly 132 to cut off the circuit, prevent dry burning, and improve the safety of using the liquid heating container.

[0119] In one specific embodiment, the body 12 includes an inner liner 121 and an outer shell 122. The inner liner 121 is installed inside the outer shell 122 and forms an inner cavity 11. A vacuum cavity 123 is formed between the outer wall of the inner liner 121 and the inner wall of the outer shell 122. The vacuum cavity 123 helps to improve the heat preservation and insulation effect of the container body 1. In this embodiment, the steam pipe 14 can be installed inside the vacuum cavity 123, which not only makes reasonable use of the unused space inside the container body 1, but also does not affect the capacity of the inner cavity 11.

[0120] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
