Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0044] In related technologies, household appliances often require structures to dissipate heat and cool the liquid in the reservoir 100, such as electric kettles that need to cool down quickly after boiling water. Natural cooling or forced air cooling of the outer wall of the reservoir 100 is commonly used. However, forced air cooling of the outer wall of the reservoir 100 is inefficient and slow. Some heat dissipation solutions add heat dissipation fins 300 to the outer wall surface to increase the heat dissipation area; however, when the reservoir is large, a large number of heat dissipation fins 300 are required, resulting in high costs.

[0045] The embodiments of this utility model are described with reference to... Figures 1-6 As shown, a liquid cooling device and an electric water bottle are provided. The liquid cooling device includes: a liquid storage box 100 with a liquid storage cavity 110; a flow-dispersing component 200 disposed in the liquid storage box 100, which is adapted to drive the liquid in the liquid storage cavity 110 to circulate; a cooling fan 400 for cooling the liquid storage box 100; and a drive motor 500, wherein there is one drive motor 500, and one end of the motor shaft of the drive motor 500 is connected to the flow-dispersing component 200 and the other end is connected to the cooling fan 400 to drive the flow-dispersing component 200 and the cooling fan 400 to work.

[0046] It is understood that in this embodiment, a liquid storage chamber 110 is formed inside the liquid storage box 100, which can store liquid. When it is necessary to cool the liquid in the liquid storage chamber 110, the flow-dispersing component 200 can be activated, driving the liquid in the liquid storage box 100 to flow. During this process, the liquid exchanges heat with the walls of the liquid storage box 100, transferring heat to these walls. Because the liquid continuously flows and mixes under the action of the flow-dispersing component 200, the liquid in the liquid storage box 100 can be cooled evenly, improving the cooling efficiency. At the same time, this circulating cooling method can also adjust the operating speed of the flow-dispersing component 200 as needed to achieve precise adjustment of the liquid cooling efficiency.

[0047] Meanwhile, in some embodiments, heat dissipation can be accelerated by installing heat sinks, fans or other heat dissipation devices on the outside of the liquid storage box 100, thereby achieving rapid cooling of the liquid.

[0048] It should be noted that the liquid in the storage box 100 can be hot water, or other liquids such as juice, coffee, milk, or milk tea. This embodiment does not make any specific limitations.

[0049] Further, refer to Figure 4 As shown, there is one drive motor 500. One end of the motor shaft of the drive motor 500 is connected to the turbulence component 200, and the other end is connected to the cooling fan 400 to drive the turbulence component 200 and the cooling fan 400 to work.

[0050] Understandably, since the turbulence component 200 and the cooling fan 400 always work simultaneously, connecting the turbulence component 200 and the cooling fan 400 to the same drive motor 500 shaft can ensure that they operate synchronously and reduce energy consumption.

[0051] Using a single drive motor 500 to simultaneously drive both the baffle assembly 200 and the cooling fan 400 avoids the energy waste associated with using two independent motors. Because they operate synchronously, the motor speed and power can be adjusted according to actual needs to achieve optimal energy efficiency. Furthermore, reducing the number of motors and their associated connections and transmission devices makes the entire cooling system more compact and space-saving, helping to lower manufacturing and maintenance costs. Moreover, since the baffle assembly 200 and the cooling fan 400 are driven by the same motor, their coordinated operation is more stable and reliable, which helps reduce system failures and downtime, improving overall system performance.

[0052] The liquid cooling device according to an embodiment of the present invention includes a liquid storage box 100 and a flow-dispersing component 200. The liquid storage box 100 forms a liquid storage cavity 110. The flow-dispersing component 200 is disposed in the liquid storage box 100 and is adapted to drive the liquid flow in the liquid storage cavity 110. It also includes a cooling fan 400 for cooling the liquid storage box 100. There is one drive motor 500, and one end of the motor shaft of the drive motor 500 is connected to the flow-dispersing component 200, and the other end is connected to the cooling fan 400 to drive the flow-dispersing component 200 and the cooling fan 400 to work. The flow-driving component 200 drives the liquid flow in the liquid storage chamber 110, enabling the liquid in the liquid storage chamber 110 to continuously exchange heat with the wall of the liquid storage box 100, thereby accelerating the cooling speed of the liquid and improving the cooling efficiency. The flow also allows the liquid to fully contact the wall of the liquid storage box 100, thus achieving more uniform and efficient heat exchange. Furthermore, the flow-driving component 200 and the cooling fan 400 are connected to the same motor shaft of the drive motor 500, which can ensure that the two operate synchronously and reduce energy consumption.

[0053] According to one embodiment of the present invention, reference is made to... Figure 4 As shown, the turbulence assembly 200 includes an impeller 240, which is disposed in the liquid storage chamber 110 and is adapted to drive the liquid flow in the liquid storage chamber 110.

[0054] In this embodiment, one end of the drive motor 500 is connected to the impeller 240, and the other end is connected to the cooling fan 400. When the impeller 240 rotates, it can drive the liquid in the liquid storage chamber 110 to flow, thereby achieving more uniform and efficient heat exchange. Combined with the air blowing of the cooling fan 400, it promotes the continuous heat exchange between the liquid in the liquid storage chamber 110 and the wall of the liquid storage box 100, thereby accelerating the cooling speed of the liquid and improving the cooling efficiency.

[0055] According to one embodiment of the present invention, reference is made to... Figure 1 and Figure 2 As shown, the turbulence assembly 200 includes a circulation pump 210 and an outlet pipe 230 and an inlet pipe 220 connected to the circulation pump 210. Both the outlet pipe 230 and the inlet pipe 220 are connected to the liquid storage chamber 110. The circulation pump 210 is adapted to drive the liquid to circulate between the liquid storage chamber 110, the outlet pipe 230 and the inlet pipe 220.

[0056] When cooling of the liquid in the storage chamber 110 is required, the circulation pump 210 can be started. The circulation pump 210 drives the liquid from the storage box 100 through the outlet pipe 230 into the circulation pump 210, and then back into the storage box 100 through the inlet pipe 220. The circulation pump 210 drives the liquid in the storage chamber 110 to circulate between the storage chamber 110, the outlet pipe 230, and the inlet pipe 220, so that the liquid in the storage chamber 110 can continuously exchange heat with the walls of the storage box 100, the outlet pipe 230, and the inlet pipe 220, thereby accelerating the cooling rate of the liquid and improving the cooling efficiency. Moreover, the circulation flow allows the liquid to fully contact the walls of the storage box 100, the outlet pipe 230, and the inlet pipe 220, thereby achieving more uniform and efficient heat exchange. During this process, the liquid exchanges heat with the walls of the liquid storage box 100, as well as the walls of the outlet pipe 230 and the inlet pipe 220, transferring heat to these walls. Because the liquid continuously flows and mixes under the action of the circulating pump 210, the liquid in the liquid storage box 100 can be cooled evenly, improving cooling efficiency.

[0057] For example, the cooling fan 400 can also cool at least one of the outlet pipe 230 and the inlet pipe 220 to further improve cooling efficiency.

[0058] According to one embodiment of the present invention, reference is made to... Figure 1 and Figure 2 As shown, at least one of the water outlet pipe 230 and the water inlet pipe 220 is provided with heat dissipation fins 300 on its exterior.

[0059] Understandably, in this embodiment, the main function of the heat dissipation fins 300 is to increase the heat dissipation area, thereby accelerating the transfer of heat from the liquid to the surrounding environment. The heat dissipation fins 300 of the outlet pipe 230 and inlet pipe 220 not only improve heat dissipation efficiency but also help maintain a stable liquid temperature. When the liquid circulates between the storage box 100, outlet pipe 230, circulation pump 210, and inlet pipe 220, the heat dissipation fins 300 help the liquid quickly dissipate heat, achieving rapid cooling and improving cooling efficiency.

[0060] When the liquid flows through the outlet pipe 230 and the inlet pipe 220 under the action of the circulating pump 210, the liquid exchanges heat with the pipe walls of the outlet pipe 230 and the inlet pipe 220. After the heat exchange, the temperature of the pipes will rise or fall accordingly. By providing heat dissipation fins 300 on the outside of at least one of the outlet pipe 230 and the inlet pipe 220, the contact area between the pipes and the surrounding air can be greatly increased, thereby accelerating the transfer and dissipation of heat and effectively improving the heat dissipation efficiency of the liquid cooling device.

[0061] It should be noted that the design of the heat dissipation fins 300 can be optimized according to specific application scenarios and requirements. For example, parameters such as the number, shape, size, and spacing of the fins can be adjusted based on factors such as the properties of the liquid, flow rate, temperature difference, and environmental conditions. Furthermore, the material of the heat dissipation fins 300 can be selected from materials with good thermal conductivity, corrosion resistance, and ease of processing, such as aluminum or copper.

[0062] According to one embodiment of the present invention, reference is made to... Figure 1 and Figure 2 As shown, the water outlet pipe 230 and the water inlet pipe 220 are arranged side by side on the same side of the liquid storage box 100, and the heat dissipation fins 300 on the outside of the water outlet pipe 230 abut against the heat dissipation fins 300 on the outside of the water inlet pipe 220; or, the heat dissipation fins 300 are an integral structure, and the heat dissipation fins 300 form mounting holes 301, through which the water outlet pipe 230 and the water inlet pipe 220 pass.

[0063] In an optional embodiment, the outlet pipe 230 and the inlet pipe 220 are arranged side by side on the same side of the liquid storage box 100, and the heat dissipation fins 300 on the outside of the outlet pipe 230 abut against the heat dissipation fins 300 on the outside of the inlet pipe 220. On the one hand, the side-by-side arrangement of the pipes and the abutting heat dissipation fins 300 make the entire device more compact in structure, reducing the space occupied, and suitable for space-constrained occasions. On the other hand, due to the close contact between the heat dissipation fins 300 on the outside of the outlet pipe 230 and the heat dissipation fins 300 on the outside of the inlet pipe 220, heat can be transferred and dissipated more quickly between the two pipes, realizing rapid heat exchange, improving the overall heat dissipation efficiency, helping to reduce the temperature of the liquid in the pipes, and improving cooling efficiency.

[0064] In another alternative embodiment, the heat dissipation fins 300 are an integral structure, and the heat dissipation fins 300 have mounting holes 301 through which the water outlet pipe 230 and the water inlet pipe 220 pass. The integral structure of the heat dissipation fins 300 can provide a continuous heat dissipation surface, effectively increasing the heat dissipation area. When the heat from the water outlet pipe 230 and the water inlet pipe 220 is transferred to the heat dissipation fins 300, the heat can be quickly dissipated to the surrounding environment through the heat dissipation fins 300, thereby improving the heat dissipation efficiency.

[0065] During manufacturing, the integrated heat sink fins 300 can be directly fitted with mounting holes 301 at preset positions. This manufacturing method is simple and direct, requiring no complex processes and making processing convenient. Furthermore, the integrated heat sink fins 300 simplify the installation process. Users simply insert the outlet pipe 230 and inlet pipe 220 into the corresponding mounting holes 301, eliminating the need for additional fixing or connection steps, significantly saving installation time and costs. The integrated design of the heat sink fins 300 also enhances its structural stability and improves reliability.

[0066] According to one embodiment of the present invention, reference is made to... Figure 2 and Figure 3 As shown, the heat dissipation fins 300 include a mounting portion 310 and a plurality of heat dissipation ribs 320. The mounting portion 310 is adapted to be sleeved on the outside of the water outlet pipe 230 or the water inlet pipe 220. The plurality of heat dissipation ribs 320 are arranged at intervals along the circumference of the mounting portion 310.

[0067] It is understood that in this embodiment, the heat dissipation fins 300 include a mounting portion 310 and a plurality of heat dissipation ribs 320. The mounting portion 310 is designed to be sleeved on the outside of the water outlet pipe 230 or the water inlet pipe 220. This design ensures that the heat dissipation fins 300 can fit tightly against the pipe, thereby maximizing the heat dissipation effect.

[0068] Meanwhile, multiple heat dissipation fins 320 are spaced circumferentially along the mounting section 310, increasing the surface area of ​​the heat dissipation fins 300 and thus increasing the contact area with air, improving heat dissipation efficiency. When the liquid temperature inside the pipe is high, heat is transferred through the pipe to the heat dissipation fins 300, and then dissipated into the surrounding air through the heat dissipation fins 320. The spacing between the heat dissipation fins 320 ensures sufficient airflow between them, further ensuring the heat dissipation effect.

[0069] According to one embodiment of the present invention, reference is made to... Figure 2 and Figure 6 As shown, the cooling fan 400 is provided with an air inlet 410 and an air outlet 420. The air inlet 410 is adapted to communicate with the outside, and the air outlet 420 faces at least one of the heat dissipation fins 300 and the liquid storage box 100.

[0070] Understandably, in this embodiment, the cooling fan 400 blows air onto at least one of the heat sink fins 300 and the liquid reservoir 100 to improve their heat dissipation efficiency. The cooling fan 400 works by using a motor to drive the fan blades to rotate, generating airflow. The air inlet 410 of the cooling fan 400 is connected to the outside, ensuring sufficient airflow. The air outlet 420 directly faces the heat sink fins 300 and / or the liquid reservoir 100, blowing the generated airflow towards these heat sources. When the cooling fan 400 is working, the airflow it generates carries away heat from the surfaces of the heat sink fins 300 and the liquid reservoir 100, thereby reducing their temperature.

[0071] In some implementations, to further improve heat dissipation efficiency, the air outlet 420 of the cooling fan 400 can be directly aimed at the surface of the heat dissipation fins 300 and the liquid storage box 100, ensuring that the generated airflow can directly act on the heat dissipation surface, thereby maximizing the heat dissipation effect.

[0072] For example, the speed and airflow of the cooling fan 400 can be adjusted according to the specific needs of the cooling device. When the cooling demand is high, the speed of the cooling fan 400 can be increased accordingly to generate a stronger cooling airflow. When the cooling demand is low, the speed of the cooling fan 400 can be appropriately reduced to reduce noise and energy consumption.

[0073] In an optional implementation, the air inlet 410 has a larger area, or there are multiple air inlets 410, allowing more air to enter the cooling fan 400 to dissipate heat from the heat dissipation fins 300 and the liquid reservoir 100, thus improving heat dissipation efficiency. Multiple air inlets 410 can be positioned in different locations, such as on opposite sides of the cooling fan 400, ensuring that the cooling fan 400 can draw in air evenly, improving the overall heat dissipation effect.

[0074] It should be noted that the cooling fan 400 can be an axial fan, a DC cooling fan, a centrifugal cooling fan, a cross-flow fan, or a mixed-flow fan, etc., and can be selected according to the specific application scenario and requirements. This embodiment does not impose any specific limitations on this.

[0075] According to one embodiment of the present invention, reference is made to... Figure 2 and Figure 6 As shown, the cooling fan 400 is located at the bottom of the liquid storage box 100, and the bottom of the liquid storage box 100 is provided with an air guide 120 to guide the air from the air outlet 420 to the side of the liquid storage box 100.

[0076] Understandably, in this embodiment, the cooling fan 400 is located at the bottom of the liquid storage box 100, and the airflow blows from bottom to top, achieving effective heat dissipation of the wall surface of the liquid storage box 100. An air guide 120 is provided at the bottom of the liquid storage box 100, which can effectively guide the airflow generated by the cooling fan 400 to the ground side of the liquid storage box 100, thereby improving heat dissipation efficiency.

[0077] In one specific embodiment, the cooling fan 400 is located at the bottom of the liquid reservoir 100, with its air outlet 420 directly facing the interior of the liquid reservoir 100. When the cooling fan 400 operates, it blows out airflow, which first contacts the bottom of the liquid reservoir 100. To ensure that the cool air can evenly cover the bottom of the liquid reservoir 100 and effectively remove heat, the bottom of the liquid reservoir 100 is designed with an air guide 120. The function of the air guide 120 is to guide the airflow generated by the cooling fan 400 to the side of the liquid reservoir 100. It can be a specially designed air duct, air guide plate, or other structure to ensure that the airflow can flow smoothly and cover a larger area of ​​the liquid reservoir 100. Through this design, the airflow can more effectively remove heat from the side of the liquid reservoir 100, reducing the overall temperature of the liquid reservoir 100.

[0078] According to one embodiment of the present invention, reference is made to... Figure 2 and Figure 5 As shown, it also includes a housing 600, which has a receiving cavity, and the cooling fan 400, the liquid storage box 100 and the turbulence assembly 200 are at least partially disposed in the receiving cavity.

[0079] It is understood that in this embodiment, the outer casing 600 forms a closed cavity for accommodating key components such as the cooling fan 400, the liquid reservoir 100, and the airflow deflector 200. In some embodiments, the cooling fan 400 and the liquid reservoir 100 can be placed entirely within the cavity, providing protection for them. The outer casing 600 may have an opening communicating with the air inlet 410 of the cooling fan 400 to allow air to enter. The circulation pump 210 can be located outside the cavity for easy maintenance and upkeep. In other embodiments, the cooling fan 400, the liquid reservoir 100, and the airflow deflector 200 can be completely enclosed within the cavity of the outer casing 600. This design can be tailored to specific usage requirements, and this embodiment does not impose any specific limitations on this.

[0080] According to one embodiment of the present invention, reference is made to... Figure 1 and Figure 2 As shown, the water outlet pipe 230 and the water inlet pipe 220 are arranged along the height direction of the liquid storage box 100, and the water outlet pipe 230 and the water inlet pipe 220 are connected to the bottom of the liquid storage chamber 110.

[0081] It is understood that in this embodiment, after the circulation pump 210 is started, liquid is drawn from the bottom of the liquid storage chamber 110 through the outlet pipe 230. The drawn liquid can be pressurized by the circulation pump 210 and then introduced back into the bottom of the liquid storage chamber 110 through the inlet pipe 220. During this process, the liquid exchanges heat with the wall of the liquid storage box 100 and the walls of the outlet pipe 230 and the inlet pipe 220 to achieve heat transfer and dissipation.

[0082] Since both the outlet pipe 230 and the inlet pipe 220 are connected to the bottom of the liquid storage chamber 110, the circulation pump 210 can directly draw liquid from the bottom of the liquid storage chamber 110 for circulation. This rapid flow of liquid at the bottom of the liquid storage chamber 110, driven by the circulation pump 210, quickly removes heat and improves cooling efficiency. Furthermore, the bottom inlet and outlet design of the liquid storage box 100 ensures that the liquid within the liquid storage chamber 110 is fully mixed and flows, preventing the formation of dead zones or areas with uneven temperature.

[0083] In an optional embodiment, both the outlet pipe 230 and the inlet pipe 220 include a straight pipe section 201, a connecting section 202, and a horizontal pipe section 203 connected in sequence. The straight pipe section 201 is arranged along the height direction of the liquid storage box 100, and the horizontal pipe section 203 can be arranged along the length or width direction of the liquid storage box 100. The connecting section 202 connects the straight pipe section 201 and the horizontal pipe section 203. In this way, the circulation pump 210 can be arranged directly above the liquid storage box 100, making the overall structure of the cooling device more compact and reducing the volume occupied by the liquid cooling device.

[0084] The straight pipe section 201 is installed along the height of the liquid storage box 100, typically starting from or near the bottom of the liquid storage box 100 and extending upwards to the connecting section 202. The main function of the straight pipe section 201 is to ensure that liquid can be directly drawn from or injected into the liquid storage box 100, thereby fully utilizing the liquid within the liquid storage box 100 and avoiding dead zones or areas with uneven temperature. The connecting section 202 connects the straight pipe section 201 and the horizontal pipe section 203. The connecting section 202 is a curved pipe section used to change the direction of liquid flow. The horizontal pipe section 203 can be installed along the length or width of the liquid storage box 100, depending on the overall layout of the cooling device and the installation space. The main function of the horizontal pipe section 203 is to guide the liquid to the inlet or outlet of the circulating pump 210. Due to the special design of the outlet pipe 230 and the inlet pipe 220, the circulating pump 210 can be positioned directly above the liquid storage box 100. This layout not only saves horizontal space but also makes the entire cooling device structure more compact and stable.

[0085] By combining the straight pipe section 201, the connecting section 202, and the horizontal pipe section 203, the total length of the pipeline is effectively increased, which directly leads to an increase in the heat exchange area. During liquid flow, a longer pipe means more liquid contact with the pipe wall, thereby increasing the opportunity for heat exchange. This increased heat exchange area helps improve the heat dissipation efficiency of the cooling device, enabling it to lower the liquid temperature more quickly.

[0086] In other embodiments, the outlet pipe 230 and the inlet pipe 220 can be arranged in a spiral pattern, which also increases the pipe length, heat exchange area, and improves liquid cooling efficiency. Furthermore, the spiral arrangement of the pipes helps improve the mixing of the liquid within the storage box 100. Because the pipes extend in a spiral shape in three-dimensional space, the liquid experiences more disturbance and rotation during flow, which helps reduce temperature stratification and dead zones, resulting in a more uniform liquid temperature. On the other hand, the spiral pipe design helps increase the residence time of the liquid within the pipe, allowing for more thorough heat exchange between the liquid and the pipe wall.

[0087] According to one embodiment of the present invention, reference is made to... Figure 1 and Figure 2 As shown, the liquid storage box 100 is provided with an outlet 102 and an inlet 101 that communicates with the outside. The outlet 102 is connected to the bottom of the liquid storage chamber 110 through a pipeline, and the inlet 101 is located at the top of the liquid storage chamber 110; or, the liquid storage box 100 has an inlet and an outlet that communicate with the outside.

[0088] In one optional embodiment, the liquid storage box 100 is provided with an outlet 102 and an inlet 101 that communicates with the outside. The outlet 102 is connected to the bottom of the liquid storage chamber 110 through a pipeline, and the inlet 101 is located at the top of the liquid storage chamber 110.

[0089] The outlet 102 can be located on the top or side of the liquid storage box 100 to facilitate the addition of liquid and connection to an external liquid source, such as a water pipe or water tank, for adding liquid to be cooled into the liquid storage box 100. For example, in some embodiments, hot water heated by an electric kettle can enter the liquid storage chamber 110 through the inlet 101, then circulate through the turbulence assembly 200, and dissipate heat through the cooling fan 400 and cooling fins 300. The outlet 102 connects to the bottom of the liquid storage chamber 110 to ensure that the liquid in the liquid storage box 100 can be fully removed during use, reducing liquid residue. When liquid needs to be cooled, it is added to the liquid storage box 100 through the inlet 101. After the liquid has been circulated and cooled for a period of time, the cooled liquid can be discharged from the liquid storage box 100 through the outlet 102.

[0090] In another alternative embodiment, the inlet 101 and the outlet 102 can be combined into one interface, that is, only one inlet and outlet are provided, and water supply and drainage are achieved by pressurizing and pumping water. This design simplifies the structure of the liquid storage box 100, reduces the number of interfaces, reduces manufacturing costs and usage complexity, and can also improve the sealing performance of the liquid storage box 100 to a certain extent.

[0091] According to a second aspect of the present invention, an electric water bottle is provided, including a liquid cooling device and a heating device as described in any of the above embodiments. The heating device is disposed in a liquid storage box 100 to heat the liquid in the liquid storage box 100.

[0092] It is understood that the electric water bottle in this embodiment is a multifunctional device that can both heat and cool liquids. It mainly includes a liquid storage box 100, a heating device, and the aforementioned liquid cooling device. This design allows users to quickly heat or cool liquids as needed.

[0093] In this embodiment, the liquid storage box 100 can be used to store liquids that need to be heated or cooled, and the heating or cooling of the liquid is achieved by controlling the operation of a heating device or a liquid cooling device. The heating device can be disposed at the bottom or side of the liquid storage box 100 to heat the liquid in the liquid storage box 100, or it can be disposed in the liquid storage cavity 110 to directly heat the liquid in the liquid storage cavity 110. For example, the heating device can be an electric heating element, such as a heating tube or heating plate, which generates heat by heating with an electric current and transfers the heat to the liquid storage box 100 and the liquid therein.

[0094] In some implementations, the heating device has a temperature control system that allows the user to set a target temperature and automatically adjust the heating power to maintain a constant liquid temperature. Users can easily set heating parameters, such as the target temperature and heating time, via the control panel.

[0095] According to one embodiment of the present invention, the electric water bottle also includes a bottle body, the bottle body having a liquid storage space and a liquid outlet communicating with the liquid storage space, the heating device being adapted to heat the liquid in the liquid storage space, and the liquid storage box 100 being connected between the liquid storage space and the liquid outlet.

[0096] For example, the inner liner of the bottle has a liquid storage space, which serves as the main water storage part of the electric water bottle and has a large volume for storing liquids to be heated (such as water). The heating device can be used to heat the water in the liquid storage space. The liquid storage box 100 is located between the liquid storage space and the liquid outlet. The liquid storage box 100 has a smaller volume than the liquid storage space and is used to receive the boiling water flowing out of the liquid storage space and to cool it quickly. The cooled boiling water flows out through the liquid outlet and is supplied to the user. By setting the liquid storage box 110 in the electric water bottle for cooling, the cooling time of boiling water can be greatly shortened, meeting the user's urgent need for drinking warm or cold water.

[0097] It is understood that since the liquid cooling device has the beneficial effects of the above embodiments, the electric water bottle will have the corresponding beneficial effects of the above embodiments. The specific implementation method can be referred to the above embodiments, and will not be repeated in this application.

[0098] Finally, it should be noted that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of the present utility model do not depart from the spirit and scope of the technical solutions of the present utility model and should be covered within the protection scope of the present utility model.
