It takes time for the water to cool down to a certain temperature before it is suitable for drinking or preparing formula, which reduces the user experience. If the lid is opened to cool the water, there is a risk of water contamination, which is not conducive to drinking or use. Utility Model Content

[0003] The main purpose of this invention is to provide an electric water bottle that improves the heat dissipation efficiency of the inner liner.

[0004] To achieve the above objectives, the electric water bottle proposed in this utility model includes:

[0005] Inner liner;

[0006] The outer shell has the inner liner inside, and a heat dissipation gap is formed between the inner liner and the outer shell. The outer shell has a first air outlet and a second air outlet that communicate with the heat dissipation gap. The first air outlet and the second air outlet are arranged at intervals along the height direction of the outer shell.

[0007] An air supply device, connected to the heat dissipation gap, is used to supply air to the inner liner through the heat dissipation gap;

[0008] Heating element for heating the inner liner; and

[0009] A water pump is used to supply water to the inner tank.

[0010] In one embodiment, the electric water bottle further includes a base, the air supply device is disposed on the base, and the outer casing is detachably mounted on the base;

[0011] The outer casing also has an air inlet that connects to the heat dissipation gap, and the air supply device is connected to the air inlet.

[0012] In one embodiment, the first air outlet and / or the second air outlet are respectively disposed on two sides of the outer casing that are opposite to each other in the circumferential direction.

[0013] In one embodiment, the first air outlet is located near the bottom side of the inner liner.

[0014] In one embodiment, the electric water bottle further includes an air guide structure, which is configured to make the flow direction of the airflow through the air inlet form an angle with the center line of the inner liner.

[0015] In one embodiment, the airflow direction through the air inlet is inclined upwards;

[0016] And / or, the air inlet is oriented at an angle;

[0017] And / or, the air inlet is provided with an air inlet grille, and the air inlet grille is inclined.

[0018] In one embodiment, the electric water bottle further includes a temperature measuring device disposed at the bottom of the inner liner.

[0019] In one embodiment, the electric water bottle further includes an electrical coupling assembly disposed between the inner liner and the outer shell;

[0020] And / or, the inner liner is provided with a water inlet, the base is provided with a water outlet coupled to the water inlet, and the water outlet is connected to the water pump.

[0021] In one embodiment, the base is provided with a mounting cavity, an air inlet and an air outlet communicating with the mounting cavity, the air outlet communicating with the air inlet, and the air supply device being disposed inside the mounting cavity.

[0022] In one embodiment, the air supply device includes a bracket and a fan. The bracket is connected to the cavity wall of the mounting cavity and has an air supply channel communicating with the air outlet. The fan is fixed to the air supply channel.

[0023] In one embodiment, the airflow through the outlet is inclined upwards.

[0024] And / or, the air outlet is tilted upwards;

[0025] And / or, the air outlet direction of the air supply channel is inclined upwards;

[0026] And / or, the air outlet is provided with an air outlet grille, and the air outlet grille is inclined upwards in the air guiding direction.

[0027] In the technical solution of this utility model, the outer shell is provided with a first air outlet and a second air outlet, the inner liner is installed inside the outer shell, and a heat dissipation gap is formed between the inner liner and the outer shell, so as to facilitate the use of the air supply device to send air to the inner liner through the heat dissipation gap to dissipate heat and improve the heat dissipation efficiency of the inner liner.

[0028] Specifically, due to the arrangement of the first and second air outlets, the airflow within the heat dissipation gap has at least two major heat exchange paths. After the airflow enters the heat dissipation gap, part of the airflow flows along the gap and exits through the first air outlet, while the other part flows along the gap and exits through the second air outlet. During this process, the airflow continuously exchanges heat with the inner liner, using multiple long heat exchange paths to accelerate the cooling of the inner liner. Furthermore, combined with the spacing between the first and second air outlets along the height of the outer shell, when the hot air around the inner liner is heated and rises naturally, the descending cold air can achieve counter-current heat exchange with the rising hot air. This helps improve the uniformity of heat exchange and reduces the risk of significant differences in water temperature stratification. At the same time, by utilizing the temperature uniformity within the heat dissipation gap, the airflow resistance can be reduced to a certain extent, increasing the airflow speed. This helps to shorten the user's waiting time and also makes it easier to reduce the requirements for the air supply device, such as reducing the energy consumption and noise of the air supply device.

[0044] Because electric kettles and other liquid heating containers boil or heat water to very high temperatures, it is not suitable for direct drinking or use. It takes time for the water to cool down to a certain temperature before it is suitable for drinking or preparing formula, which reduces the user experience. If the lid is opened to cool the water, there is a risk of water contamination, which is not conducive to drinking or use.

[0045] To solve this technical problem, this utility model proposes an electric water bottle.

[0046] Please see Figures 1 to 4In one embodiment of this utility model, the electric water bottle includes an inner liner 10, an outer shell 20, a ventilation device 30, a heating element 53, and a water pump 54. The inner liner 10 is housed inside the outer shell 20, and a heat dissipation gap 24 is formed between the inner liner 10 and the outer shell 20. A first air outlet 22 and a second air outlet 23 communicating with the heat dissipation gap 24 are provided on the outer shell 20. The first air outlet 22 and the second air outlet 23 are arranged at intervals along the height direction of the outer shell 20. The ventilation device 30 communicates with the heat dissipation gap 24 and is used to deliver air to the inner liner 10 through the heat dissipation gap 24. The heating element 53 is used to heat the inner liner 10. The water pump 54 is used to supply water to the inner liner 10, thereby improving the heat dissipation efficiency of the inner liner 10.

[0047] In the technical solution of this utility model, the outer shell 20 is provided with a first air outlet 22 and a second air outlet 23, the inner liner 10 is installed inside the outer shell 20, and a heat dissipation gap 24 is formed between the inner liner 10 and the outer shell 20, so that the air supply device 30 can supply air to the inner liner 10 through the heat dissipation gap 24 to dissipate heat and improve the heat dissipation efficiency of the inner liner 10.

[0048] Specifically, due to the arrangement of the first air outlet 22 and the second air outlet 23, the airflow within the heat dissipation gap 24 has at least two major heat exchange paths. That is, after the airflow enters the heat dissipation gap 24, part of the airflow flows along the heat dissipation gap 24 and flows out through the first air outlet 22, while part of the airflow flows along the heat dissipation gap 24 and flows out through the second air outlet 23. During this process, the airflow continuously exchanges heat with the inner liner 10, using multiple long heat exchange paths to accelerate the cooling of the inner liner 10. Furthermore, combined with the spaced arrangement of the first air outlet 22 and the second air outlet 23 in the height direction of the outer shell 20, when the hot air around the inner liner 10 is heated and rises naturally, the descending cold air can achieve counter-current heat exchange with the rising hot air, which is beneficial to improving the heat exchange uniformity and reducing the risk of significant differences in water temperature stratification. At the same time, by utilizing the temperature uniformity within the heat dissipation gap 24, the airflow resistance can be reduced to a certain extent, and the air velocity can be increased, thereby helping to shorten the user's waiting time and also facilitating the reduction of requirements on the air supply device 30, such as reducing the energy consumption and noise of the air supply device 30.

[0049] Please see Figures 1 to 4 In this embodiment of the invention, the electric water bottle further includes a base 40, the air supply device 30 is disposed on the base 40, and the outer shell 20 is detachably installed on the base 40. This allows the user to easily remove the outer shell 20 with the inner liner 10 and add water or clean the inner liner 10, thereby improving the ease of use of the electric water bottle. However, this design is not limited to this; in other embodiments, the outer shell 20 and the base 40 are an integral structure.

[0050] When the base 40 and the outer shell 20 are detachably connected, the outer shell 20 is also provided with an air inlet 21 that connects to the heat dissipation gap 24. The air supply device 30 is connected to the air inlet 21 to ensure that the airflow generated by the air supply device 30 can enter the heat dissipation gap 24 through the air inlet 21, thereby realizing the flow of air in the heat dissipation gap 24 and heat exchange with the inner liner 10, thereby achieving the cooling of the inner liner 10.

[0051] Please see Figure 1 and Figure 3 In this embodiment of the present invention, the first air outlet 22 and / or the second air outlet 23 and the air inlet 21 are respectively disposed on two sides of the outer shell 20 that are opposite to each other in the circumferential direction. In this way, the airflow blown out of the air inlet 21 needs to cross the inner liner 10 when it flows to the first air outlet 22 and / or the second air outlet 23. Compared with the air inlet 21, the first air outlet 22 and the second air outlet 23 being located on the same side of the inner liner 10, the airflow can have a longer heat exchange path, increase the area where the airflow directly exchanges heat with the inner liner 10, reduce the water temperature stratification difference, and improve the cooling efficiency of the inner liner 10.

[0052] Optionally, in an embodiment of this utility model, the first air outlet 22 is disposed near the bottom side of the inner liner 10. Specifically, the air inlet 21 may be further positioned between the first air outlet 22 and the second air outlet 23. It is understood that the second air outlet 23 is located above the first air outlet 22. In this case, the second air outlet 23 may be directly above the first air outlet 22, or the second air outlet 23 and the first air outlet 22 may be offset. The air inlet 21, located between the first air outlet 22 and the second air outlet 23, can extend the heat exchange path of the airflow to the corresponding first air outlet 22 and second air outlet 23, thereby improving the heat exchange effect. Of course, in other embodiments, the air inlet 21 is disposed near the bottom side of the inner liner 10; or the air inlet 21 is disposed near the top of the inner liner 10.

[0053] Optionally, in an embodiment of this utility model, the electric water bottle further includes an air guide structure. The air guide structure is used to make the flow direction of the airflow through the air inlet 21 form an angle with the center line of the inner liner 10. In this way, compared with the airflow blowing vertically towards the inner liner 10, the airflow blowing towards the inner liner 10 at a certain angle increases the area where the airflow directly exchanges heat with the inner liner 10, which facilitates the transfer of heat and the flow of air on the surface of the inner liner 10, thereby achieving heat dissipation.

[0054] Specifically, in an embodiment of this utility model, the airflow direction through the air inlet 21 is inclined upwards; such as Figure 3As shown, the airflow entering from the air inlet 21 is tilted upwards and blown out. Part of the airflow diffuses towards the top of the inner liner 10 and flows to the second air outlet 23. At this time, a large amount of airflow after heat exchange is blown out from the second air outlet 23, and a small amount of airflow can flow downwards towards the first air outlet 22 and exchange heat with the rising hot air in a countercurrent. Because the airflow direction through the air inlet 21 is tilted upwards, the path of some airflow diffusing towards the bottom of the inner liner 10 is extended, which facilitates the airflow to fully exchange heat with the rising hot air. Part of the airflow after heat exchange flows to the first air outlet 22, and the other part can diffuse towards the top of the inner liner 10 and flow to the second air outlet 23. In this way, the wind resistance can be reduced and the wind speed can be increased, so that users do not have to wait too long to get warm water. At the same time, the requirements of the electric water bottle on the air supply device 30 can be reduced, which is conducive to reducing the energy consumption of the air supply device 30. It can also reduce noise by reducing the turbulence of airflow. Of course, in other embodiments, the airflow direction through the air inlet 21 is inclined downwards.

[0055] Please see Figure 2 In an embodiment of this utility model, the air inlet 21 is tilted, that is, the angle between the center line of the air inlet 21 and the wall surface where the air inlet 21 is located is not equal to 90 degrees. When the airflow direction through the air inlet 21 is tilted upward, the air inlet 21 is tilted upward.

[0056] Please see Figure 2 In an embodiment of this utility model, the air inlet 21 is provided with an air inlet grille 25, which is inclined, that is, the air guiding direction of the air inlet grille 25 is inclined. At this time, the air guiding direction of the air inlet grille 25 can be parallel to the extension direction of the center line of the air inlet 21. Of course, the angle between the center line of the air inlet 21 and the wall surface where the air inlet 21 is located can be equal to 90 degrees. When the airflow direction through the air inlet 21 is inclined upward, the air guiding direction of the air inlet grille 25 is inclined upward.

[0057] Please see Figure 1 In this embodiment of the invention, the electric water bottle further includes a temperature measuring device 51 disposed at the bottom of the inner liner 10. This temperature measuring device 51 is used to detect the temperature within the heat dissipation gap 24. Since the heat dissipation gap 24 surrounds the outer side of the inner liner 10, the temperature within the heat dissipation gap 24 can more accurately reflect the actual water temperature of the inner liner 10, ensuring the measurement accuracy of the temperature measuring device 51. When the first air outlet 22 and / or the second air outlet 23 and the air inlet 21 are respectively disposed on opposite sides of the outer shell 20 in its circumferential direction, the temperature measuring device 51 can be disposed away from the air inlet 21 and the air supply device 30, facilitating the measurement of the temperature after heat exchange and further improving the accuracy of the measured temperature. The temperature measuring device 51 can be configured as a temperature probe.

[0058] Optionally, in an embodiment of the present invention, the electric water bottle further includes an electrical coupling component 52 disposed between the inner liner 10 and the outer shell 20. The periphery of the electrical coupling component 52 is provided with a surrounding plate 26. The surrounding plate 26 can block the airflow from flowing toward the electrical coupling component 52, reduce the impact of the airflow on the electrical coupling component 52, and thus ensure the normal operation of the electric water bottle.

[0059] In addition, such as Figure 1 As shown, the bottom of the inner liner 10 is also provided with a heating element 53 and a temperature measuring device 51. The heating element 53 is used to heat the water in the inner liner 10. Both the heating element 53 and the temperature measuring device 51 are located inside the enclosure 26, which can make reasonable use of the space inside the enclosure 26 while ensuring their operation, thereby improving the overall compactness of the electric water bottle.

[0060] Optionally, in an embodiment of this utility model, the inner liner 10 is provided with a water inlet, and the base 40 is provided with a water outlet coupled to the water inlet. The water outlet is connected to the water pump 54. Thus, the water inlet penetrates the outer shell 20, and the base 40 is provided with a water inlet pipe 55 that can be connected to the water outlet and the water inlet. The water inlet pipe 55 is connected to the water pump 54. Thus, under the action of the water pump 54, when the outer shell 20 is installed on the base 40, water can be added to the inner liner 10 through the water inlet using the water inlet pipe 55 that connects the water pump 54 and the water outlet, thereby improving the convenience of adding water to the electric water bottle.

[0061] Optionally, in an embodiment of this utility model, the base 40 is provided with an installation cavity 41, an air inlet 42 and an air outlet 43 communicating with the installation cavity 41, the air outlet 43 communicating with the air inlet 21, and the air supply device 30 being disposed within the installation cavity 41. In this way, the air supply device 30 is effectively hidden within the installation cavity 41, improving the overall aesthetics of the base 40, while ensuring the normal operation of the air supply device 30. Furthermore, since the air inlet 42 communicates with the air outlet 43 through the installation cavity 41, when the outer shell 20 is installed on the base 40, under the action of the air supply device 30, the airflow outside the electric water bottle enters the installation cavity 41 through the air inlet 42 and flows to the air outlet 43. Then, the air outlet 43 communicates with the air inlet 21, and the airflow is finally blown into the heat dissipation gap 24 through the air inlet 21, thereby achieving heat dissipation of the inner liner 10 and reducing the water temperature.

[0062] Optionally, in an embodiment of this utility model, the air supply device 30 includes a bracket 32 ​​and a fan 31. The bracket 32 ​​is connected to the cavity wall of the mounting cavity 41 and has an air supply channel 321 communicating with the air outlet 43. The fan 31 is fixed to the air supply channel 321. This arrangement facilitates the secure mounting of the fan 31 on the base 40 via the bracket 32, improving the assembly reliability of the fan 31. It also facilitates docking with the air outlet 43 via the air supply channel 321, improving alignment efficiency. The fan 31 can be configured as an axial flow fan 31. When the wind resistance within the heat dissipation gap 24 is low and the wind speed is high due to the setting of the first air outlet 22 and the second air outlet 23, the fan 31 can reduce its rotation speed, thereby improving the energy-saving effect of the air supply device 30. At the same time, it provides a quieter and more comfortable environment for users by operating with low noise.

[0063] Optionally, in an embodiment of this utility model, the airflow direction through the air outlet 43 is inclined upwards; such as Figure 3 As shown, the airflow from the outlet 43 is blown out at an upward angle, and the airflow entering through the inlet 21 is also blown out at an upward angle. Part of the airflow diffuses toward the top of the inner liner 10 and flows to the second outlet 23. At this time, a large amount of airflow after heat exchange is blown out from the second outlet 23, and a small amount of airflow can flow downward toward the first outlet 22 and exchange heat with the rising hot air in a countercurrent. Because the airflow direction through the inlet 21 is set to be upward, the path of some airflow diffuses toward the bottom of the inner liner 10 is extended, which facilitates the airflow to fully exchange heat with the rising hot air. Part of the airflow after heat exchange flows to the first outlet 22, and the other part can diffuse toward the top of the inner liner 10 and flow to the second outlet 23. In this way, the wind resistance can be reduced and the wind speed can be increased, so that users do not have to wait too long to get warm water. At the same time, the requirements of the electric water bottle on the air supply device 30 can be reduced, which is conducive to reducing the energy consumption of the air supply device 30. It can also reduce noise by reducing the turbulence of the airflow. Of course, in other embodiments, the airflow direction through the air inlet 21 is inclined downwards.

[0064] Please see Figure 2 In one embodiment of the present invention, the air outlet 43 is inclined upwards, that is, the angle between the center line of the air outlet 43 and the wall surface where the air outlet 43 is located is not equal to 90 degrees. Of course, in other embodiments, the air outlet 43 is inclined downwards.

[0065] Please see Figure 2In one embodiment of the present invention, the air outlet direction of the air supply channel 321 is inclined upward. In this case, the air outlet direction of the air supply channel 321 can be parallel to the extension direction of the center line of the air outlet 43, which effectively reduces the risk of airflow turbulence caused by the inconsistency between the air outlet direction of the air supply channel 321 and the orientation of the air outlet 43. Of course, in other embodiments, the air outlet direction of the air supply channel 321 is inclined downward.

[0066] Please see Figure 2 In one embodiment of the present invention, the air outlet 43 is provided with an air outlet grille 44, and the air outlet grille 44 is inclined upwards. In this case, the air outlet grille 44 can be parallel to the extension direction of the center line of the air outlet 43. Of course, in other embodiments, the air outlet grille 44 is inclined downwards.

[0067] In addition, by setting the air inlet grille 25 and the air outlet grille 44, when the outer shell 20 and the base 40 are used separately, excessively large openings are avoided at the air inlet 21 and the air outlet 43, thus improving the safety of using the electric water bottle. The setting of the air inlet grille 25 and the air outlet grille 44 can ensure the smooth passage of air while ensuring the integrity of the appearance of both the outer shell 20 and the base 40.

[0068] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
