Liquid heating container

Abstract

This application provides a liquid heating container, including a container body with an inner cavity; and a container lid, including a lid body and a sealing assembly. The lid body has an air inlet channel, a pressure relief hole, and an exhaust channel. The pressure relief hole communicates with the inner cavity and the exhaust channel, respectively, and the air inlet channel communicates with both the inner cavity and the exhaust channel. The sealing assembly is installed on the lid body and is used to open the air inlet channel, allowing steam in the inner cavity to flow through the air inlet channel to the exhaust channel. The sealing assembly is also used to close the air inlet channel when the liquid heating container is tilted, preventing liquid in the inner cavity from flowing through the air inlet channel to the exhaust channel. The sealing assembly enables the liquid heating container to prevent tipping, reducing the risk of liquid leaking out of the inner cavity through the air inlet and exhaust channels when the container is tilted. The pressure relief hole can continuously release pressure and exhaust air, preventing the steam in the inner cavity from being unable to escape when the air inlet channel is closed, thus avoiding safety hazards and improving the user experience.

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 reducing internal pressure. However, if the container is tilted, liquid may leak out through the venting channel, causing leakage. Utility Model Content

[0003] This application provides a liquid heating container that can solve the problem of easy water leakage from the exhaust channel when the liquid heating container is tilted in the prior art.

[0004] This application provides a liquid heating container, comprising: a container body having an inner cavity; and a container lid including a lid body and a sealing assembly. The lid body has an air inlet channel, a pressure relief hole, and an exhaust channel. The pressure relief hole is connected to the inner cavity and the exhaust channel, respectively, and the air inlet channel is connected to both the inner cavity and the exhaust channel. The sealing assembly is installed on the lid body and is used to open the air inlet channel to allow steam in the inner cavity to flow through the air inlet channel to the exhaust channel. The sealing assembly is also used to close the air inlet channel when the liquid heating container is tilted, thereby preventing liquid in the inner cavity from flowing through the air inlet channel to the exhaust channel.

[0005] In the above solution, under normal conditions (when the liquid heating container is not tilted), the sealing component opens the air inlet channel, allowing steam in the inner cavity to flow to the exhaust channel. When the liquid heating container tilts (when the user pours water or when the liquid heating container accidentally tilts), the sealing component closes the air inlet channel to prevent liquid in the inner cavity from flowing to the exhaust channel. Therefore, by setting the sealing component, the anti-tipping function of the liquid heating container can be achieved, reducing the risk of liquid in the inner cavity leaking out through the air inlet and exhaust channels when the liquid heating container tilts. The pressure relief hole is connected to both the inner cavity and the exhaust channel, allowing steam generated by heating the liquid in the inner cavity to flow to the exhaust channel through the pressure relief hole, thus venting to the outside. When the liquid heating container tilts, the sealing component does not block the pressure relief hole, meaning the pressure relief hole can continuously release pressure and exhaust air, preventing the steam in the inner cavity from being unable to escape when the air inlet channel is closed, thus avoiding safety hazards and improving the user experience.

[0006] In one possible design, the sealing assembly includes a bracket and a sealing element, the bracket being fixedly installed on the cover; the bracket and the cover form a first accommodating space, the first accommodating space being connected to the inner cavity, the air inlet channel and the pressure relief hole respectively; the sealing element is movably installed in the first accommodating space, and when the liquid heating container is tilted, the sealing element can move within the first accommodating space to close the air inlet channel.

[0007] In the above scheme, under normal conditions, the sealing component is moved away from the air intake channel by gravity, keeping the air intake channel open. Part of the steam inside the cavity flows to the exhaust channel via the first receiving space and the air intake channel, while another part flows to the exhaust channel via the first receiving space and the pressure relief hole. When the liquid heating container is tilted, the sealing component moves relative to the support under gravity within the first receiving space to close the air intake channel. At this time, the steam inside the cavity flows to the exhaust channel only along the path of the first receiving space and the pressure relief hole. By setting a structure where the support and the sealing component cooperate, a separate control device is not required. The sealing component can open or close the air intake channel solely under the action of gravity, simplifying the structure of the sealing assembly and making it more convenient for users to operate.

[0008] 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.

[0009] 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.

[0010] In one possible design, there is an included angle α between the sidewall and the bottom wall of the first part, wherein the included angle α satisfies: 110°≤α≤140°.

[0011] In the above scheme, when the included angle α satisfies: 110°≤α≤140°, the sealing component is more likely to slide along the inclined surface when the liquid heating container is tilted, which helps to improve the reliability of the sealing component.

[0012] In one possible design, the bracket further includes an air inlet pipe fixedly connected to the bracket body, and the first accommodating space communicates with the inner cavity through the air inlet pipe.

[0013] In the above scheme, under normal conditions, at least part of the first part is housed within the intake pipe. This improves the stability of the sealing component and increases the capacity of the first accommodating space, facilitating rapid steam discharge. A certain gap exists between the sealing component and the intake pipe, allowing steam in the inner cavity to flow into the first accommodating space through this gap, and then flow to the exhaust channel via the intake passage and / or pressure relief hole.

[0014] In one possible design, the container lid further includes a base plate fixedly installed on the lid body, the base plate and the lid body forming a second receiving space, and the sealing assembly located in the second receiving space; the base plate is provided with a through hole, and at least a portion of the air intake pipe extends into the inner cavity through the through hole.

[0015] In the above scheme, the base plate can limit the air intake pipe, which helps to improve the installation stability of the bracket body, thereby improving the reliability of the sealing component.

[0016] In one possible design, the side wall of the support body is provided with a hollow section, and the first receiving space communicates with the inner cavity through the hollow section.

[0017] In the above scheme, the hollowed-out part facilitates steam flow and helps improve the steam discharge efficiency.

[0018] In one possible design, the container lid further includes a baffle movably mounted on the bracket and located at the end of the air intake passage away from the sealing assembly; the baffle is used to open the air intake passage when the steam pressure in the air intake passage is greater than a preset value; the baffle is also used to close the air intake passage when the steam pressure in the air intake passage is less than or equal to the preset value.

[0019] In the above scheme, when the steam pressure in the inlet channel is less than or equal to a preset value, the baffle can close the inlet channel under gravity to prevent steam from flowing into the exhaust channel, thereby reducing the amount of steam discharged. This prevents 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 support under the action of steam pressure to open the inlet channel. The steam in the inlet channel can then flow into the exhaust channel to achieve rapid pressure relief and exhaust, improving the safety of the liquid heating container. By installing the baffle on the support, not only are parts saved and installation of the baffle facilitated, but the installation accuracy and stability of the baffle are also improved, ensuring that the baffle can accurately cover the inlet channel, thereby improving the reliability of the baffle.

[0020] In one possible design, the container body includes a fixedly connected body and a bottom cover, with a steam pipe installed inside the body, the two ends of which are respectively connected to the exhaust channel and the bottom cover.

[0021] In the above solution, 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, preventing steam from flowing out from the top of the container and scalding the user.

[0022] In one possible design, the body includes an inner liner and an outer shell, the inner liner being installed inside the outer shell, and a vacuum cavity being formed between the outer wall of the inner liner and the inner wall of the outer shell; the steam pipe is installed inside the vacuum cavity.

[0023] In the above scheme, the vacuum chamber is beneficial to improve the heat preservation and insulation effect of the container. The steam pipe is installed in the vacuum chamber, which not only makes reasonable use of the idle space inside the container, but also does not affect the capacity of the inner cavity.

[0024] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit this application. Attached Figure Description

[0082] 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

[0083] 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.

[0084] 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.

[0085] 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.

[0086] 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.

[0087] 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.

[0088] 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.

[0089] The following describes the water outlet structure of container lid 2, such as... Figure 2 As 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 25 is also provided at the water outlet 214, which is used to open or close the water outlet 214. Figure 3As shown, when the outlet valve 25 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 25 closes the outlet hole 214, the outlet valve 25 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 26, which is rotatably mounted inside the cover body 21. The water outlet button 26 has a pressing part 261 and a driving part 262. At least a portion of the pressing part 261 is exposed outside the cover body 21, and the end of the water outlet valve 25 away from the outlet hole 214 is slidably mounted on the driving part 262. Figure 3 As shown, when water needs to be poured out, the user can press down on the pressing part 261 so that the driving part 262 can drive the water outlet valve 25 away from the water outlet 214, thereby opening the water outlet 214. Figure 2 As shown, a return spring 263 is installed on the drive unit 262. The two ends of the return spring 263 abut against the drive unit 262 and the cover 21, respectively. During the process of the pressing part 261 being pressed and the drive unit 262 moving upwards, the return spring 263 is in a compressed state. Therefore, when the water is poured out, the user only needs to stop pressing down on the pressing part 261, and the drive unit 262 will reset under the restoring force of the return spring 263, thereby driving the water outlet valve 25 to move towards the water outlet hole 214 to close the water outlet hole 214. Therefore, by setting the water outlet valve 25 and the water outlet button 26, 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 from the water outlet 124 and causing leakage when the liquid heating container is accidentally tilted, thus improving the safety of the liquid heating container.

[0090] 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 213. The air inlet channel 211 is connected to the inner cavity 11 and the exhaust channel 213, respectively, and the exhaust channel 213 is used to connect with 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 213 to achieve the effect of exhaust and pressure relief, and avoid excessive pressure in the inner cavity 11, which may cause safety hazards.

[0091] This embodiment also includes a blocking component 22. For example... Figure 2 As shown, the sealing assembly 22 is installed on the cover 21. Under normal conditions, the sealing assembly 22 is used to open the air intake passage 211, so that the steam in the inner cavity 11 can flow to the exhaust passage 213 through the air intake passage 211. 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 22 is used to close the air inlet channel 211 to prevent the liquid in the inner cavity 11 from flowing to the exhaust channel 213 through the air inlet channel 211. Therefore, by setting the sealing component 22, 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 213 when the liquid heating container is tilted.

[0092] In this embodiment, as Figure 2 As shown, the cover 21 is also provided with a pressure relief hole 212, which is connected to the inner cavity 11 and the exhaust channel 213 respectively. The steam generated by heating the liquid in the inner cavity 11 can also flow through the pressure relief hole 212 to the exhaust channel 213, thereby flowing to the outside to achieve exhaust. Figure 3 As shown, when the liquid heating container is tilted, the sealing component 22 does not block the pressure relief hole 212, meaning the pressure relief hole 212 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 212 can be one or more; this embodiment does not limit this.

[0093] It should be noted that the diameter of the pressure relief hole 212 is small. When the liquid heating container is tilted, the risk of the liquid in the inner cavity 11 flowing to the exhaust channel 213 through the pressure relief hole 212 is small. Even if a small amount of liquid flows to the exhaust channel 213 through the pressure relief hole 212, it still meets the safety standards for liquid heating containers and will not cause any safety hazards.

[0094] In one specific implementation, such as Figure 2 As shown, the sealing assembly 22 includes a bracket 221 and a sealing element 222. The bracket 221 is fixedly installed on the cover 21, and the bracket 221 and the cover 21 form a first receiving space 223. The first receiving space 223 is connected to the inner cavity 11, the air intake channel 211, and the pressure relief hole 212. The sealing element 222 is movably installed in the first receiving space 223. Under normal conditions, the sealing element 222 is moved away from the air intake channel 211 by gravity, so that the air intake channel 211 is in an open state. Part of the steam in the inner cavity 11 can flow to the exhaust channel 213 through the first receiving space 223 and the air intake channel 211, and another part of the steam can flow to the exhaust channel 213 through the first receiving space 223 and the pressure relief hole 212. Figure 3As shown, when the liquid heating container is tilted, the sealing element 222 can move relative to the support 221 within the first receiving space 223 under the action of gravity, thereby closing the air intake passage 211. At this time, the steam in the inner cavity 11 flows to the exhaust passage 213 only along the path of the first receiving space 223 and the pressure relief hole 212. By setting the structure in which the support 221 cooperates with the sealing element 222, there is no need to set a separate control device. The sealing element 222 can open or close the air intake passage 211 under the action of gravity alone, which simplifies the structure of the sealing assembly 22 and makes it more convenient for users to operate.

[0095] In another embodiment, the pressure relief hole 212 may not be connected to the inner cavity 11 through the first receiving space 223, but may be directly connected to the inner cavity 11.

[0096] In one specific implementation, combined with Figure 4 As shown, the bracket 221 includes a bracket body 221a, which is fixedly connected to the cover 21 and forms a first receiving space 223. The inner sidewall of the bracket body 221a is provided with an inclined surface 221aa. The sealing member 222 includes a first part 222a and a second part 222b fixedly connected. The first part 222a has a frustum structure. When the liquid heating container is tilted, the sidewall of the first part 222a can slide and engage with the inclined surface 221aa to increase the moving speed of the sealing member 222, thereby enabling the sealing member 222 to quickly close the air intake channel 211. The second part 222b 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 member 222.

[0097] like Figure 5 As shown, there is an included angle α between the side wall and the bottom wall of the first part 222a, which satisfies the condition: 110°≤α≤140°. Specifically, it can be 110°, 115°, 120°, 125°, 130°, 135°, or 140°, and this embodiment does not limit this. If the included angle α is too small (e.g., less than 110°) or too large (e.g., greater than 140°), it will affect the sliding fit between the side wall of the first part 222a and the inclined surface 221aa, causing the sealing component 222 to easily stop during sliding and fail to close the air intake passage 211. Therefore, when the included angle α satisfies: 110°≤α≤140°, the sealing component 222 is more likely to slide along the inclined surface 221aa when the liquid heating container is tilted, thereby improving the reliability of the sealing component 22.

[0098] Combination Figure 4 and Figure 6As shown, the bracket 221 also includes an air inlet pipe 221b fixedly connected to the bracket body 221a, and the first accommodating space 223 communicates with the inner cavity 11 through the air inlet pipe 221b. In normal operation, at least a portion of the first part 222a is accommodated in the air inlet pipe 221b, which improves the stability of the sealing member 222 and increases the capacity of the first accommodating space 223, facilitating rapid steam discharge. Specifically, in normal operation, there is a certain gap between the sealing member 222 and the air inlet pipe 221b, through which steam in the inner cavity 11 can flow into the first accommodating space 223 and then flow to the exhaust channel 213 via the air inlet channel 211 and / or the pressure relief hole 212.

[0099] In this embodiment, under normal conditions, if the steam pressure inside the intake pipe 221b is too high and pushes up the sealing member 222, causing the intake channel 211 to close, the pressure relief hole 212 can release pressure and exhaust air, thereby ensuring the internal and external pressure balance of the container cover 2, which helps the sealing member 222 to quickly reset and ensures that the intake channel 211 can work normally.

[0100] like Figure 4 As shown, the side wall of the support body 221a can also be provided with a hollow portion 221ab. The first receiving space 223 is connected to the inner cavity 11 through the hollow portion 221ab, which is beneficial to improving the steam discharge efficiency. The number of hollow portions 221ab can be one or more, and this embodiment does not limit this.

[0101] In this embodiment, the intake pipe 221b and the perforated portion 221ab 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 221ab can ensure smooth steam discharge when the intake pipe 221b is blocked.

[0102] In one specific implementation, such as Figure 2 and Figure 3 As shown, the container lid 2 also includes a base plate 23, which is fixedly installed on the lid body 21. The base plate 23 has multiple water passage holes 233. Liquid in the inner cavity 11 flows through the water passage holes 233 to the water outlet hole 214, meaning the base plate 23 has a filtering function, which improves the user experience. The base plate 23 and the lid body 21 form a second receiving space 231, within which the sealing assembly 22 is located. The base plate 23 also has a through hole 232, through which at least a portion of the air inlet pipe 221b extends into the inner cavity 11. In this case, the base plate 23 can limit the movement of the air inlet pipe 221b, improving the installation stability of the support body 221 and thus enhancing the reliability of the sealing assembly 22.

[0103] The base plate 23 can be made of stainless steel, which has the advantages of high structural strength and easy cleaning.

[0104] In this embodiment, the steam in the inner cavity 11 can also enter the second accommodating space 231 through the water passage 233, and then enter the first accommodating space 223 through the hollow part 221ab, which increases the steam discharge path and helps to improve the steam discharge efficiency.

[0105] In one specific embodiment, the container cap 2 further includes a baffle 24, which is movably mounted on the end of the air intake passage 211 away from the sealing assembly 22, such as... Figure 6 As shown, when the steam pressure in the intake channel 211 is less than or equal to a preset value, the baffle 24 can close the intake channel 211 under the action of gravity, thereby preventing the steam in the intake channel 211 from flowing to the exhaust channel 213, 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 7 As shown, when the steam pressure in the air intake channel 211 is greater than the preset value, the baffle 24 can move relative to the cover 21 under the action of steam pressure to open the air intake channel 211. The steam in the air intake channel 211 can flow to the exhaust channel 213 to achieve rapid pressure relief and exhaust, thereby improving the safety of the liquid heating container.

[0106] It should be noted that the preset steam pressure value 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 24 with one of different materials or weights, and this embodiment does not limit the adjustment method.

[0107] In this embodiment, the baffle 24 can be slidably or rotatably connected to the cover 21, or slidably or rotatably connected to the bracket 221. This embodiment takes the rotatable connection between the baffle 24 and the bracket 221 as an example to describe the installation structure of the baffle 24 in detail.

[0108] like Figure 6 As shown, the baffle 24 includes a baffle body 243, a limiting rib 241, and a rotating shaft 242. The baffle body 243 is used to open or close the air intake passage 211, and the rotating shaft 242 is used to realize the rotatable connection between the baffle 24 and the bracket 221. Figure 7 As shown, the limiting rib 241 is used to abut against the cover 21 during the rotation of the baffle 24 relative to the bracket 221, so as to limit the rotation angle of the baffle 24 and prevent the baffle 24 from failing to reset itself due to excessive rotation angle. This ensures that the baffle 24 can automatically close 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 24.

[0109] like Figure 4As shown, the bracket 221 also includes a mounting portion 221c and a fixing post 221d. The fixing post 221d is fixedly connected to the cover 21 so that the bracket body 221a and the cover 21 can form a first receiving space 223. The cover 21 is provided with a mounting hole corresponding to the mounting portion 221c. At least a portion of the mounting portion 221c passes through the mounting hole to be rotatably connected to the rotating shaft 242, so that the baffle 24 and the bracket 221 form a rotatable connection, which helps to improve the connection stability between the cover 21, the baffle 24, and the bracket 221. Moreover, by mounting the baffle 24 on the bracket 221, not only can parts be saved and the installation of the baffle 24 be facilitated, but the installation accuracy of the baffle 24 can also be improved, ensuring that the baffle body 243 can accurately cover the air intake channel 211, thereby improving the reliability of the baffle 24. In addition, the mounting hole can also limit the mounting portion 221c, which helps to improve the installation stability of the bracket 221. In one specific embodiment, the container lid 2 further includes a partition 27 and a sealing ring 28. The partition 27 is fixedly connected to the lid body 21, and the partition 27 and the lid body 21 form a steam chamber 271. The steam chamber 271 communicates with the air inlet channel 211 and the air outlet channel 213, respectively. A baffle 24 is installed inside the steam chamber 271. Along the height direction of the container lid 2, the sealing ring 28 is clamped between the partition 27 and the lid body 21. By setting the partition 27 and the sealing ring 28, steam can be prevented from flowing towards the water outlet button 26, thereby reducing the risk of steam flowing out from the top of the container lid 2 and scalding the user.

[0110] In this embodiment, the water dispensing button 26 can be rotatably mounted on the partition 27 to reduce the number of parts and thus reduce the volume of the container lid 2.

[0111] 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 213 and the bottom cover 13, respectively. The steam in the exhaust channel 213 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 it to overheat, improving the user's convenience and comfort.

[0112] 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.

[0113] like Figure 1As 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.

[0114] 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.

[0115] 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.
