[0047] The present utility model provides a liquid heating container, which can be an electric kettle, a health kettle, etc.

[0048] Please refer to Figures 1 to 5 , in an embodiment of the present utility model, the liquid heating container includes:

[0049] A container body 1 having a receiving cavity 11. The container body 1 further includes a heating device, and the heating device can heat the liquid in the receiving cavity 11; and

[0050] A lid assembly 2 detachably installed on the container body 1, and the lid assembly 2 can cover the receiving cavity 11. The lid assembly 2 is provided with a heat dissipation structure. The inner side of the heat dissipation structure communicates with the receiving cavity 11, and the outer side communicates with the external space of the liquid heating container, and can enable the receiving cavity 11 to exchange air flow with the external air to cool the liquid in the receiving cavity 11.

[0051] Specifically, a receiving cavity 11 is provided in the container body 1, and the container body is provided with a heating device. The heating device can heat the liquid in the receiving cavity 11, so that the liquid in the receiving cavity 11 reaches a boiling state. The lid assembly 2 is detachably installed on the container body, which facilitates the disassembly and cleaning of the lid assembly, and further facilitates the cleaning of the liquid heating container. And the lid assembly 2 can cover the receiving cavity 11. When the lid assembly 2 covers the receiving cavity 11, it can be hermetically connected to the container body 1 through a sealing structure such as a sealing ring, thereby improving the sealing performance of the liquid heating container and further improving the heating efficiency of the liquid heating container; the lid assembly 2 can also be opened relative to the receiving cavity 11, which facilitates the user to add water.

[0052] The capacity of the liquid heating container is generally large, so the boiled water needs a long cooling time before it can be drunk by the user. For example, it takes about 9 hours for 5L of boiled water to cool down naturally from boiling to 45°C, which brings great inconvenience to the user. If the cover is opened directly for cooling, the accommodating chamber 11 is directly opened, which is easy to pollute the water source during the cooling process. Therefore, a heat dissipation structure is provided on the cover assembly 2, and the inner side of the heat dissipation structure is connected to the accommodating chamber 11, and the outer side is connected to the external space of the liquid heating container, so that the accommodating chamber 11 is connected to the external space through the heat dissipation structure, and the low-temperature air in the external space is introduced into the accommodating chamber 11, so as to directly dissipate the heat for the liquid surface in the accommodating chamber 11, and at the same time, the high-temperature gas in the accommodating chamber 11 can be discharged, so as to complete the heat exchange between the accommodating chamber 11 and the external low-temperature air, so as to cool the liquid in the accommodating chamber 11, so as to assist the liquid in the accommodating chamber 11 in heat dissipation, thereby accelerating the cooling efficiency of the liquid heating device and reducing the waiting time for users.

[0053] Compared with the prior art, the container body 1 includes an outer shell and an inner liner arranged in the outer shell, and a heat dissipation structure is arranged at the base of the outer shell, and the heat dissipation structure cools the surface of the inner liner to achieve the purpose of cooling the liquid in the accommodating cavity 11. In this solution, the external low-temperature gas can directly cool the surface of the liquid, further improving the cooling efficiency of the liquid heating device.

[0054] The inner side of the heat dissipation structure is the side of the accommodating cavity 11 that the heat dissipation structure faces, and the outer side of the heat dissipation structure is the side of the heat dissipation structure that faces away from the accommodating cavity 11. The heating device can be arranged at the base of the container body 1 to indirectly heat the liquid in the accommodating cavity 11 by heating the inner tank, or it can be directly extended into the accommodating cavity 11 to directly heat the accommodating cavity 11.

[0055] In the embodiments of the present invention, please refer to Figures 1 to 5 The heat dissipation structure includes an exhaust channel 21 provided in the cover assembly 2, and an exhaust device 22 is provided in the exhaust channel 21, the exhaust channel 21 is used to discharge the gas in the accommodating chamber 11 to the external space, and the exhaust device 22 is used to accelerate the airflow velocity in the exhaust channel 21. Specifically, the inner side of the exhaust channel 21 is connected to the accommodating chamber 11, and the outer side is connected to the external space, and is used to discharge the steam in the accommodating chamber 11 to the external space. The exhaust device 22 is provided in the exhaust channel 21, and the exhaust device 22 is used to accelerate the airflow velocity in the exhaust channel 21, thereby accelerating the airflow exchange between the accommodating chamber 11 and the external air, and further accelerating and improving the cooling efficiency of the liquid heating device.

[0056] To introduce the external low-temperature gas into the accommodating chamber 11, the structure of the cover assembly 2 itself or the matching gap between the cover assembly 2 and the container body 1 can be utilized, such as utilizing the connection between the water outlet and the accommodating chamber 11, or a through hole can be directly set on the shell cover assembly to facilitate the introduction of the external low-temperature gas into the accommodating chamber 11.

[0057] In another embodiment of the present utility model, the heat dissipation structure includes an intake passage 23 provided in the cover assembly 2, and an intake device is provided in the intake passage 23. The intake passage 23 is used to introduce external low-temperature gas into the accommodation chamber 11, and the intake device is used to accelerate the air flow rate in the intake passage 23. To discharge the high-temperature steam in the accommodation chamber 11 to the external space, the structure of the cover assembly 2 itself or the fitting gap between the cover assembly 2 and the container body 1 can be utilized. For example, by using the connection between the water outlet and the accommodation chamber 11, or a through hole can be directly provided on the cover assembly 2, so as to facilitate discharging the high-temperature steam in the accommodation chamber 11 to the external space.

[0058] Please refer to Figures 4 to 8 , in the embodiment of the present utility model, the exhaust device 22 includes an exhaust box 221 and an exhaust fan 222 provided in the exhaust box 221. An exhaust hole 223 is provided on one side of the exhaust box 221 facing the external space, and a steam inlet hole 224 communicating with the accommodation chamber 11 is also provided on the exhaust box 221. Specifically, when the exhaust fan 222 operates, a negative pressure area is formed on the side facing the accommodation chamber 11, so as to discharge the high-temperature steam in the accommodation chamber 11 to the external space. And the exhaust fan 222 is provided in the exhaust box 221, which helps to improve the structural integrity of the exhaust device 22, can also protect the exhaust fan 222, and is convenient for the installation of the exhaust device 22 on the cover assembly 2. An exhaust hole 223 is provided on one side of the exhaust box 221 facing the external space, and a steam inlet hole 224 communicating with the accommodation chamber 11 is also provided on the exhaust box 221, so that after the high-temperature steam in the accommodation chamber 11 enters the exhaust passage 21, it further enters the interior of the exhaust box 221 through the steam inlet hole 224 and is discharged through the exhaust hole 223.

[0059] To facilitate the installation of the exhaust fan 222, in this embodiment, the exhaust box 221 includes a box body 2214 and a box cover 2215 that are spliced with each other. The exhaust fan 222 is detachably installed in the box body 2214, and the box cover 2215 covers the box body 2214. Thus, it is convenient for the disassembly and assembly of the exhaust device 22, and thus convenient for the user to clean. And in order to ensure the overall sealing effect of the exhaust box 221, a first sealing ring 2216 is provided on the periphery of the splicing part of the box body 2214 and the box cover 2215, so as to reduce the possibility of accidental air leakage at the splicing part of the box body 2214 and the box cover 2215. In other embodiments, the exhaust box 221 is integrally formed, and the exhaust fan 222 is not detachably installed in the exhaust box 221. In other embodiments, the exhaust device 22 can be directly configured as an exhaust fan 222, and the exhaust fan 222 is provided in the exhaust passage 21.

[0060] Further, the exhaust box 221 includes a top wall 2211 and a bottom wall 2212 which are oppositely arranged, and side walls 2213 arranged between the top wall 2211 and the bottom wall 2212; the exhaust hole 223 is arranged on the top wall 2211, and the steam inlet hole 224 is arranged on the side wall 2213, and the steam inlet hole 224 is located between the exhaust fan 222 and the bottom wall 2212. Specifically, the top wall 2211 is the side wall 2213 of the exhaust box 221 facing the external space, and the bottom wall 2212 is the side wall 2213 of the exhaust box 221 facing the accommodation cavity 11. The exhaust hole 223 is arranged on the top wall 2211, so as to facilitate the exhaust of the exhaust box 221. The steam inlet hole 224 is arranged on the side wall 2213, and the steam inlet hole 224 is located between the exhaust fan 222 and the bottom wall 2212, so that the high-temperature steam entering the exhaust passage 21 enters the exhaust box 221 from the side wall 2213 of the exhaust box 221. Compared with the steam inlet hole 224 being arranged on the bottom wall 2212 of the exhaust box 221, in this solution, on the one hand, the flow path of the high-temperature steam flowing into the exhaust box 221 can be extended, so as to further promote the liquefaction of the high-temperature steam and reduce the discharge of water vapor. On the other hand, it can also reduce the possibility that the water vapor liquefied in the exhaust box 221 flows back to the accommodation cavity 11 through the steam inlet hole 224, thereby reducing the possibility of condensate water polluting the water source and reducing the psychological discomfort of users.

[0061] To reduce the possibility of condensate water flowing back to the accommodation cavity 11 through the steam inlet hole 224, in an embodiment of the present utility model, a receiving groove is arranged at the bottom of the exhaust box 221, and the receiving groove is used to receive the liquid formed by the liquefaction of the water vapor in the exhaust box 221. Specifically, the receiving groove is used to collect the liquefied condensate water in the exhaust box 221, so as to temporarily store the condensate water. The user can pour out the condensate water from the exhaust box 221 regularly. Therefore, the cover assembly 2 is provided to be detachable, so as to facilitate the pouring out of the condensate water. Compared with the cover assembly 2 being rotatably installed on the container body 1, it can also avoid the condensate water flowing back to the accommodation cavity due to the rotation of the cover assembly 2 relative to the container body 1. In this embodiment, the steam inlet hole 224 is arranged on the side wall 2213, and the steam inlet hole 224 is at a certain distance from the bottom wall 2212, so that the bottom wall 2212 and a part of the side wall 2213 below the steam inlet hole 224 jointly enclose to form the receiving groove, so that there is no need to additionally process a receiving groove on the bottom wall 2212. In other embodiments, the bottom wall 2212 can also be partially recessed downward to form a receiving groove, or a groove-shaped structure can be formed on a part of the bottom wall 2212.

[0062] Of course, in other embodiments, the steam inlet hole 224 can be arranged on the bottom wall 2212, or arranged on both the bottom wall 2212 and the side wall 2213 on the side away from the exhaust fan 222 at the same time. The exhaust hole 223 can also be arranged on the side wall 2213 close to the top wall 2211. At this time, the exhaust box 221 protrudes from the outer surface of the cover assembly 2.

[0063] Further, the exhaust device 22 is detachably installed in the exhaust passage 21. Specifically, the exhaust device 22 is detachably installed in the exhaust passage 21. On the one hand, it facilitates the daily cleaning of the exhaust device 22 and the cover assembly 2, reducing the possibility of dirt accumulation in the installation gap between the exhaust device 22, the cover assembly 2, and the exhaust device 22 and the cover assembly 2. On the other hand, it facilitates pouring out the condensed water in the exhaust box 221.

[0064] Among them, the exhaust device 22 can be installed in the exhaust passage 21 through a snap-fit structure, or in the form of interference or transitional fit, or through fasteners. In other embodiments, the exhaust device 22 is not detachably installed in the exhaust passage 21, such as the exhaust device 22 is directly bonded in the exhaust passage 21.

[0065] And in the embodiment of the present utility model, the exhaust device 22 is installed outside the exhaust passage 21. Compared with the exhaust device 22 installed inside the exhaust passage 21 or on the side of the exhaust passage 21 facing the accommodation cavity 11, on the one hand, it facilitates the disassembly of the exhaust device 22, and on the other hand, it increases the distance between the exhaust device 22 and the accommodation cavity 11, so that the water vapor in the accommodation cavity 11 can be liquefied to a certain extent before entering the exhaust device 22, which helps to reduce the discharge of water vapor. In other embodiments, the exhaust device 22 is installed inside the exhaust passage 21; or, the exhaust device 22 is installed on the side of the exhaust passage 21 facing the accommodation cavity 11, or the exhaust device 22 directly fills the entire exhaust passage 21, the steam inlet hole 224 of the exhaust device 22 is directly communicated with the accommodation cavity 11, and the exhaust hole 223 of the exhaust device 22 is directly communicated with the external space.

[0066] To ensure the exhaust effect, there needs to be a certain distance between the exhaust fan 222 and the bottom wall 2212 to facilitate the exhaust fan 222 to discharge high-temperature steam. In the embodiment of the present utility model, the distance between the exhaust fan 222 and the bottom wall 2212 is greater than or equal to 3 mm and less than or equal to 8 mm. Please refer to Figure 8 , the distance between the exhaust fan 222 and the bottom wall 2212 is D, and the distance between the exhaust fan 222 and the bottom wall 2212 is the distance between the lower surface of the exhaust fan 222 and the inner surface of the bottom wall 2212. If the distance between the exhaust fan 222 and the bottom wall 2212 is less than 3 mm, the space between the bottom wall 2212 of the exhaust fan 222 is small, and the negative pressure area formed is small, which is not conducive to the high-temperature steam entering the exhaust box 221 and affects the exhaust effect of the exhaust device 22; if the distance between the exhaust fan 222 and the bottom wall 2212 is greater than 8 mm, the overall thickness of the exhaust box 221 is thicker, and the corresponding thickness required for the cover assembly 2 is also thicker, which is not conducive to the lightweight of the product and also increases unnecessary material costs.

[0067] For the convenience of installing the exhaust fan 222, in the embodiment of the present utility model, please refer to Figure 7 , a positioning member 225 is further provided in the exhaust box 221, and the positioning member 225 is used to position the exhaust fan 222. Specifically, in this embodiment, the positioning member 225 is configured as a plurality of positioning posts provided on the bottom wall 2212, and the exhaust fan 222 is installed on the positioning posts, so as to position the installation height and installation position of the exhaust fan 222, thereby ensuring the distance between the exhaust fan 222 and the bottom wall 2212. In addition, the positioning member 225 can also provide a supporting effect for the exhaust fan 222. For the convenience of installing the exhaust fan 222, the positioning member 225 has a positioning end, and the exhaust fan 222 is provided with a positioning groove. During installation, the positioning end is inserted into the positioning groove, so that there is no need to provide an additional fixing structure to fix the exhaust fan 222.

[0068] For the convenience of installing and disassembling the exhaust device 22, in the embodiment of the present utility model, please refer to Figures 1 to 6 , a handle portion 226 protruding towards the external space is provided on the outer side of the exhaust device 22. Specifically, since the exhaust device 22 is provided in the exhaust passage 21, and in order to ensure the overall appearance integrity of the cover assembly 2, the outer surface of the exhaust box 221 is usually flush with the outer surface of the cover assembly 2. Therefore, the exhaust device 22 is often not easily disassembled. Therefore, the handle portion 226 is provided on the outer side of the exhaust device 22, and the handle portion 226 protrudes towards the external space, so that the user can pull out the exhaust device 22 from the exhaust passage 21 through the handle portion 226, thereby facilitating the installation and disassembly of the exhaust device 22.

[0069] To further facilitate the air exchange between the accommodation cavity 11 and the external space, in the embodiment of the present utility model, the heat dissipation structure further includes an air intake passage 23 provided on the cover assembly 2, and the air intake passage 23 is used to introduce external air into the accommodation cavity 11. As Figure 5 , in the direction indicated by the arrow in the figure, which is the flow direction of the air flow in the cover assembly 2, the high-temperature steam in the accommodation cavity 11 is discharged through the exhaust device 22 via the exhaust passage 21, and its internal pressure drops, thereby introducing external cold air into the accommodation cavity 11, thereby further dissipating heat from the liquid in the accommodation cavity 11. And additionally providing the air intake passage 23 can also accelerate the air exchange between the accommodation cavity 11 and the external space and improve the cooling efficiency of the liquid heating container.

[0070] In an embodiment of the present utility model, a handle groove 24 is provided on a side of the cover assembly 2 facing away from the accommodation cavity 11, and an air inlet end 231 of the air inlet passage 23 is provided in the handle groove 24. Specifically, the handle groove 24 can facilitate a user to open and close the accommodation cavity 11, and is configured in a groove shape, which helps to reduce the overall thickness of the cover assembly 2 and improve the aesthetic degree of the cover assembly 2. And the air inlet end 231 of the air inlet passage 23 is provided in the handle groove 24. Compared with the air inlet end 231 being provided at other positions of the handle groove 24, this solution facilitates the user to hide the air inlet end 231, so that on one hand, it can reduce the entry of external dust or dirt into the accommodation cavity 11 through the air inlet passage 23, and on the other hand, it can improve the overall appearance integrity of the cover assembly 2. In other embodiments, the handle groove 24 can also be configured as a handle groove 24 provided on the outer side of the cover assembly 2 and protruding into the external space.

[0071] Further, the air inlet ends 231 are provided at opposite ends of a side wall 2213 of the handle groove 24. Specifically, the air inlet ends 231 are provided at opposite ends of the side wall 2213 of the handle groove 24, that is, the air inlet ends 231 are provided at opposite ends in the length direction of the handle groove 24, so as to make way for the human hand and reduce the possibility of the human hand directly contacting the air inlet ends 231 when the human hand extends into the handle groove 24, and reduce the pollution of the air inlet ends 231. In addition, the air inlet ends 231 are provided on the side wall 2213 of the handle groove 24, so as to further hide the air inlet ends 231.

[0072] To reduce the pollution of the accommodation cavity 11 by external impurities, in an embodiment of the present utility model, at least a projection of the air inlet end 231 in the vertical direction does not coincide with at least a part of a projection of the remaining section of the air inlet passage 23 in the vertical direction. Specifically, let the remaining section of the air inlet passage 23 except the air inlet end 231 be the main body section. Therefore, at least a projection of the air inlet end 231 in the vertical direction does not coincide with at least a part of a projection of the main body section in the vertical direction, so that there must be a corner between the air inlet section 231 and the main body section. Compared with the air inlet passage 23 that penetrates directly, this solution can extend the air inlet path of the air inlet passage 23, increase the difficulty of external impurities entering the accommodation cavity 11 through the air inlet passage 23, and thus reduce the possibility of external impurities polluting the accommodation cavity 11.

[0073] And at least a projection of the air inlet end 231 in the vertical direction does not coincide with at least a part of a projection of the remaining section of the air inlet passage 23 in the vertical direction. That is, the main body section itself can also be configured as a channel section connected by multiple bends, so as to further extend the flow path of the air inlet passage and reduce the possibility of external impurities polluting the accommodation cavity 11.

[0074] In an embodiment of the present utility model, at least the air outlet end of the air inlet channel 23 is located on the side of the air inlet end 231 away from the exhaust channel 21. That is, the overall air inlet channel extends in a direction away from the exhaust channel 21, which helps to extend the overall air path of the liquid heating container 1, thereby increasing the contact area between the external air flow and the liquid surface and improving the heat dissipation efficiency.

The air inlet channel 23 and the exhaust channel 21 are both provided on the upper cover 25; a first through hole 261 is provided on the side of the lower cover 26 close to the exhaust channel 21, and a second through hole 262 is provided on the side of the lower cover 26 close to the air inlet channel 23. Specifically, the upper cover 25 and the lower cover 26 of the cover assembly 2 are spliced together, and the air inlet channel 23 and the exhaust channel 21 are both provided on the upper cover 25, which facilitates the processing of the cover assembly 2. In this embodiment, a second sealing ring 27 is provided between the lower cover 26 and the container body 1 to seal the gap between the cover assembly 2 and the container body 1 and ensure the sealing degree of the accommodation cavity 11. A first through hole 261 is provided on the side of the lower cover 26 close to the exhaust channel 21, and the first through hole 261 communicates with the exhaust channel 21. The water vapor generated in the accommodation cavity 11 first enters the first through hole 261 and then enters the exhaust channel 21, so that the lower cover 26 can further block the steam from entering the exhaust channel 21, thereby promoting the liquefaction of the steam. A second through hole 262 is provided on the side of the lower cover 26 close to the air inlet channel 23, and the second through hole 262 communicates with the air inlet channel 23, so that the lower cover 26 can further block external dust or impurities from entering the accommodation cavity 11.

The first connector 12 is provided on the side of the container body 1 facing the cover assembly 2. The cover assembly 2 is provided with a second connector 271 electrically connected to the heat dissipation structure, and the side of the second connector 271 facing the container body 1. When the cover assembly 2 covers the accommodation cavity 11, the first connector 12 contacts the second connector 271, thereby realizing the electrical connection between the control module and the heat dissipation structure, facilitating the control module to control the operation of the exhaust device 22, and realizing the electrical connection between the control module and the heat dissipation structure through the contact of the first connector 12 and the second connector 271. Compared with using wire connection, this solution can reduce the wire chaos.

[0077] In order to ensure the stable contact between the first connector 12 and the second connector 271, in the embodiment of the present utility model, the cover assembly 2 is detachably installed on the container body 1, and an installation protrusion 13 is provided inside the accommodation cavity 11.
