Description

Technical Field

[0001] The utility model relates to the field of cooking equipment, in particular to a liquid heating device. Background Art

[0002] The electric thermos of the related art usually has a container body with a volume of more than two liters, and the container body is used to hold liquid. The bottom of the container body has a heating plate, which heats the liquid in the container body. After reaching the set temperature, the water pump pumps the liquid in the container body to the water outlet to provide the liquid. However, it usually takes a long time for the liquid in the container body to reach the set temperature, and the liquid at the set temperature cannot be provided in time. Utility Model Content

[0003] Therefore, the purpose of the present invention is to provide a liquid heating device to at least solve the problem that hot water cannot be produced in time due to a long time to boil water.

[0004] One aspect of an embodiment of the utility model provides a liquid heating device, which includes: a container body, used to hold liquid; an inner liner cover, which is arranged in the container body and surrounds a heating chamber with the bottom wall of the container body, a liquid inlet is provided on the inner liner cover, which is used to supply the liquid in the container body to the inner liner cover, and a liquid outlet is provided on the bottom wall of the container body, which is connected to the heating chamber and is used to provide the liquid in the heating chamber to the outside of the container body; a heating component, which is arranged on the lower surface of the bottom wall of the container body corresponding to the position of the heating chamber.

[0005] The liquid heating device provided in the embodiment of this aspect has an inner shell provided inside the container body, the volume of the heating chamber in the inner shell is smaller than the volume of the container body, and the heating component is arranged on the outer surface of the bottom wall of the container body corresponding to the position of the heating chamber, so as to concentrate the heating of the liquid in the smaller heating chamber. Compared with the related art in which the heating component needs to heat the liquid in the entire container body, the heating component can concentrate and quickly heat a small amount of liquid in the heating chamber, so that the liquid in the heating chamber quickly reaches the set temperature and is then discharged through the liquid outlet on the bottom wall of the container body. This greatly shortens the heating time, thereby facilitating the liquid heating device to provide the user with liquid of the set temperature in a timely manner.

[0006] In addition, the liquid outlet is directly arranged in the area where the inner tank cover is located and connected to the heating chamber, so that a portion of the liquid at the set temperature in the heating chamber is preferentially discharged through the liquid outlet without being disturbed by the liquid outside the inner tank cover, thereby enabling the liquid heating device to provide liquid at the set temperature in a timely manner.

[0007] In some embodiments, the volume of the heating chamber is less than one-half of the volume of the container body. The smaller the volume of the heating chamber, the faster the liquid inside it is heated to the set temperature. Therefore, the volume of the heating chamber is designed to be less than half of the volume of the container body. Compared with the heating component directly heating the liquid in the entire container body, the heating time can be shortened, allowing the user to obtain the liquid at the set temperature faster, improving the user experience.

[0008] In some embodiments, the volume of the heating chamber accounts for less than one quarter of the volume of the container body. The smaller volume of the heating chamber can greatly shorten the heating time, allowing the user to obtain liquid at a set temperature more quickly.

[0009] In some embodiments, the volume of the heating chamber is greater than or equal to 200 ml and less than or equal to 500 ml. Most water containers such as cups or bottles have a volume of 500 ml or less, so the volume of the heating chamber is between 200 ml and 500 ml, so that the liquid in the heating chamber heats up quickly and is conducive to meeting the drinking water needs of users.

[0010] In some embodiments, the outer edge of the heating component does not exceed the bottom edge of the inner shell, which means that the outer edge of the heating component is located inside the bottom edge of the inner shell in the horizontal direction, so that the heating component can concentrate on heating the liquid in the inner shell and avoid heat dispersion.

[0011] In some embodiments, the heating component includes a heating pipe, or the heating component includes a heat conducting plate and a heating pipe located on the lower surface of the heat conducting plate. The bottom wall of the container body is usually made of a heat conducting material, so the heating pipe can be directly arranged on the bottom wall of the container body, or the heating pipe can heat the liquid in the inner liner cover through the heat conducting plate and the bottom wall of the container body.

[0012] In some embodiments, the heating chamber has a guide channel connected to the liquid inlet, and the guide channel is used to extend the flow path of the liquid from the liquid inlet to the liquid outlet.

[0013] In these embodiments, the flow path of the liquid from the liquid inlet to the liquid outlet is extended by utilizing the flow guide channel. Then, when the liquid in the inner liner cover is heated to the set temperature and flows out from the liquid outlet, the flow guide channel can delay the unheated liquid in the container body from quickly entering the inner liner cover and flowing toward the liquid outlet. During this period, it is beneficial for the liquid at the set temperature in the inner liner cover to enter the liquid outlet more and preferentially, thereby increasing the amount of liquid at the set temperature that the user can quickly obtain.

[0014] In some embodiments, the guide channel extends along the circumference of the inner liner cover, so that the liquid introduced from the liquid inlet can flow along the circumference of the inner side wall of the inner liner cover.

[0015] In these embodiments, the guide channel can extend roughly along the circumference of the inner tank cover, so that after the liquid enters the heating chamber, it can flow roughly along the circumference of the inner wall of the inner tank cover and away from the position of the liquid outlet, greatly extending the flow path of the liquid from the liquid inlet to the liquid outlet.

[0016] In some embodiments, the flow guiding channel is formed by enclosing the flow guiding tube, which has a simple structure and is easy to process.

[0017] In some embodiments, guide ribs are provided on the inner side of the inner liner cover or the bottom wall of the container, and the guide ribs, the inner wall of the inner liner cover, and the bottom wall of the container body together enclose a guide channel. The structure is simple and easy to process. In some embodiments, guide ribs are provided on the inner wall of the inner liner cover or the bottom wall of the container body to extend the flow path from the liquid inlet to the liquid outlet. When the liquid in the inner liner cover is heated to the set temperature and flows out of the liquid outlet, the guide ribs can prevent the unheated liquid in the container body from quickly entering the inner liner cover and flowing to the liquid outlet. During this period, it is beneficial for the liquid at the set temperature in the inner liner cover to enter the liquid outlet more and preferentially, thereby increasing the amount of liquid at the set temperature that the user can quickly obtain.

[0018] In some embodiments, a groove is provided in the middle of the bottom wall of the container body, the bottom of the inner liner cover is embedded in the groove, the liquid outlet is provided on the bottom wall of the groove, and the heating component is provided below the bottom wall of the groove and does not exceed the outer edge of the bottom wall of the groove.

[0019] In these embodiments, a groove is provided on the bottom wall of the container body, so that the inner liner cover can be accurately installed in the container body by aligning the position of the groove, thereby improving assembly efficiency. Moreover, the heating component is arranged below the bottom wall of the groove, and the distance from the non-recessed portion of the bottom wall of the container body is increased, and the heat can be transferred to the groove side wall of the groove to heat the liquid in the inner liner cover, which is conducive to concentrating the heat generated by the heating component into the heating cavity, thereby improving heating efficiency.

[0020] In some embodiments, the bottom of the inner liner cover is welded to the bottom wall of the container body. The inner liner cover and the container body are firmly connected, and the two are sealed together, thereby preventing liquid outside the inner liner cover from entering the heating chamber through the gap between the inner liner cover and the bottom wall of the container body.

[0021] In some embodiments, the inner liner cover is detachable and can be placed in the container body. When the inner liner cover needs to be cleaned, the inner liner cover can be removed from the container body for cleaning, which is convenient for cleaning. When the container body needs to be cleaned, the inner liner cover can also be removed, which is convenient for cleaning the inside of the container body, avoiding the inconvenience of cleaning due to the obstruction or interference of the inner liner cover, and avoiding the accumulation of impurities at the bottom corners of the inner liner cover. In addition, when not needed, the inner liner cover can also be removed, so that there is enough space in the container body to accommodate other liquids or ingredients to be heated.

[0022] In some embodiments, a magnetic member is disposed on the lower surface of the bottom wall of the container body, and the magnetic member is used to adsorb the liner cover onto the bottom wall of the container body.

[0023] In these embodiments, the inner liner cover is fixed to the bottom wall of the container body by magnetic attraction. On the one hand, the inner liner cover can fit tightly to the bottom wall of the container body to prevent the liquid outside the inner liner cover from entering the heating chamber in large quantities through the gap between the inner liner cover and the bottom wall of the container body. On the other hand, it is convenient to take and put the inner liner cover. It can be taken out by simply pulling the inner liner cover outwards to overcome the magnetic attraction. When the inner liner cover is placed in the container body, the magnetic part can rely on the magnetic attraction to guide the inner liner cover to move to a specified position, which is conducive to the correspondence between the heating component and the inner liner cover. Moreover, under the influence of the magnetic attraction, the inner liner cover can be stably installed in the container body and is not easy to move. In addition, the magnetic part is located on the lower surface of the bottom wall of the container body, with a simple structure, and will not affect the internal structure of the container body, and there is no risk of water leakage.

[0024] In some embodiments, a groove is provided in the middle portion of the bottom wall of the container body, and the heating component is provided below the bottom wall of the groove and does not exceed the outer edge of the bottom wall of the groove; the bottom of the inner liner cover has a flange structure extending outward, and the flange structure is built on the bottom wall surface of the container body at the outer periphery of the groove, and a magnetic part is provided at the outer periphery of the groove for adsorbing the flange structure on the bottom wall of the container body.

[0025] In these embodiments, by providing a groove on the bottom wall of the container body, the heating component is provided below the bottom wall of the groove, and the magnetic component is provided on the periphery of the groove to avoid the heating component, so that the magnetism of the magnetic component can be prevented from being affected by the high temperature of the heating component and becoming ineffective. Specifically, the heat generated by the heating component needs to pass through the bottom wall and the side wall of the groove to continue to be transferred outward to the magnetic component, and the bottom wall and the side wall of the groove will first exchange heat with the liquid in the heating chamber, and then continue to transfer heat outward, and the heat transferred out is very small, so the probability of failure of the magnetic component can be effectively reduced.

[0026] In addition, the bottom of the inner liner cover has a flange structure extending outward, and the flange structure cooperates with the magnetic part to increase the magnetic attraction area, which is conducive to the stable installation of the inner liner cover in the container body without movement.

[0027] In some embodiments, the liquid heating device also includes: a container cover, which is arranged at the top opening of the container body; a stabilizing structure, which is arranged at the bottom of the container cover or the top of the inner liner cover, and the stabilizing structure is provided with air holes, and the container cover presses the inner liner cover against the bottom wall of the container body through the stabilizing structure.

[0028] In these embodiments, when the container lid is closed on the container body, the inner liner cover is pressed against the bottom wall of the container body by the stabilizing structure below. Even during the heating process, the inner liner cover will not move in the container body, which is beneficial for the corresponding distribution of the heating cavity and the heating component up and down.

[0029] In some embodiments, the bottom of the inner liner cover has a first elastic pad, and the inner liner cover contacts the bottom wall of the container body through the first elastic pad. On the one hand, it can prevent the inner liner cover and the bottom wall of the container body from being worn due to rigid friction, and on the other hand, it can make the inner liner cover and the bottom wall of the container body relatively sealed, preventing the liquid outside the inner liner cover from entering the heating chamber in large quantities through the gap between the inner liner cover and the bottom wall of the container body.

[0030] In some embodiments, based on the situation that the stabilizing structure is arranged at the bottom of the container cover, a second elastic pad is arranged at the bottom of the stabilizing structure or the top of the inner liner cover, and the stabilizing structure contacts the inner liner cover through the second elastic pad; based on the situation that the stabilizing structure is arranged at the top of the inner liner cover, a third elastic pad is arranged at the top of the stabilizing structure or the bottom of the container cover, and the container cover contacts the stabilizing structure through the third elastic pad. Rigid friction can be avoided and wear can be reduced.

[0031] In some embodiments, the liquid inlet is arranged at the bottom of the side wall of the inner container cover, which is beneficial for allowing the liquid to enter the heating chamber through the liquid inlet when there is less liquid in the container.

[0032] In some embodiments, an air outlet is provided at the top of the inner liner cover, and the height of the air outlet is higher than the rated liquid level height of the container body. On the one hand, it is convenient for exhaust. On the other hand, the high position of the air outlet can prevent the liquid outside the inner liner cover from entering the heating chamber through the air outlet, thereby causing the relatively small heating chamber surrounded by the inner liner cover to fail.

[0033] In some embodiments, the inner liner cover includes a hollow cover body and a hollow air column. The hollow cover body is trumpet-shaped with openings at the top and bottom. The larger opening of the trumpet-shaped one side faces the bottom of the container body. The liquid inlet is arranged at the bottom of the side wall of the hollow cover body. The hollow air column is connected to the top opening of the hollow cover body and extends vertically upward. The top opening of the hollow air column is configured as an air outlet. The inner liner cover has a simple structure, and the trumpet-shaped hollow cover body has the characteristics of being distributed over a large area corresponding to the heating component and having a small capacity, which is conducive to quickly heating the liquid in the heating chamber to a set temperature. Moreover, the hollow air column has a small volume, which is convenient for exhaust. When the inner liner cover and the container body are detachably connected, it is also convenient for the user to hold the hollow column to take and place the inner liner cover.

[0034] In some embodiments, the liquid heating device further comprises a housing and a pump body disposed in the housing, the housing has a water outlet, the container body is disposed in the housing, and the pump body is connected to the liquid outlet and the water outlet through a pipeline for pumping liquid to the water outlet, thereby realizing the automatic liquid discharge function of the liquid heating device.

[0061] In electric thermoses of related art, the volume of the container body for holding liquid is generally large, with a small one being two liters and a large one being five liters, ten liters or even more. When the user needs hot water, the heating plate at the bottom of the container body will heat the entire container body, and the heating time is relatively long, resulting in the user being unable to drink hot water in time, resulting in a poor user experience.

[0062] Based on this, an embodiment of the utility model provides a liquid heating device, so that the heating component 30 can concentrate on heating a small amount of liquid without heating the liquid in the entire container body 10, which is conducive to the small amount of liquid quickly reaching the set temperature, so that the user can quickly obtain liquid at the set temperature.

[0063] The following will be combined Figures 1 to 6 The liquid heating device provided in the embodiment of the utility model is introduced.

[0064] like Figures 1 to 3 As shown, one aspect of an embodiment of the utility model provides a liquid heating device, which includes: a container body 10, used to hold liquid; an inner tank cover 20, which is arranged in the container body 10 and surrounds a heating chamber 210 with the bottom wall of the container body 10, and a liquid inlet 220 connecting the inside and the outside is provided on the inner tank cover 20, and a liquid outlet 110 is provided on the bottom wall of the container body 10, and the liquid outlet 110 is connected to the heating chamber 210, and is used to provide the liquid in the heating chamber 210 to the outside; a heating component 30, which is arranged on the lower surface of the bottom wall of the container body 10 corresponding to the position of the heating chamber 210.

[0065] The liquid heating device provided by the embodiment of this aspect has an inner shell 20 arranged inside the container body 10, the volume of the heating chamber 210 in the inner shell 20 is smaller than the volume of the container body 10, and the heating component 30 is arranged on the lower surface of the bottom wall of the container body 10 corresponding to the position of the heating chamber 210, so as to concentrate the heating of the liquid in the heating chamber 210 with a smaller volume. Compared with the related art in which the heating component 30 needs to heat the liquid in the entire container body 10, the heating component 30 can concentrate and quickly heat a small amount of liquid in the heating chamber 210, so that the liquid in the heating chamber 210 quickly reaches the set temperature, and then is discharged through the liquid outlet 110 on the bottom wall of the container body 10, which greatly shortens the heating time, thereby facilitating the liquid heating device to provide liquid of the set temperature in a timely manner.

[0066] In addition, the liquid outlet 110 is directly arranged in the area where the inner tank cover 20 is located and connected to the heating chamber 210, so that the liquid with the set temperature in the heating chamber 210 is preferentially discharged through the liquid outlet 110 without being disturbed by the liquid outside the inner tank cover 20, thereby achieving the liquid heating device providing the set temperature liquid in a timely manner.

[0067] In addition, the container body 10 can still be designed to have a larger volume to store a large amount of liquid, so that the liquid heating device can have the functions of storing a large amount of liquid and quickly heating a small amount of liquid.

[0068] In a specific application, after the liquid is injected into the container body 10, the liquid can enter the heating chamber 210 through the liquid inlet 220 on the inner liner cover 20, and the liquid inside and outside the inner liner cover 20 reaches a balanced state. When heating is required, the heating component 30 heats the liquid in the heating chamber 210 centrally. During the heating process, although the inner and outer spaces of the inner liner cover 20 are still connected through the liquid inlet 220, as the temperature rises, the pressure inside the inner liner cover 20 increases, and the liquid outside the inner liner cover 20 is not easy to enter the heating chamber 210 through the liquid inlet 220, and the existence of the liquid inlet 220 will not significantly affect the rapid heating of the liquid to the set temperature. After the heating is completed, the liquid at the set temperature in the heating chamber 210 can flow out from the lower liquid outlet 110, so that the liquid heating device can provide the liquid at the set temperature in time.

[0069] Of course, after a certain amount of liquid flows out of the heating chamber 210, the liquid inside the container body 10 and outside the inner liner cover 20 will enter the heating chamber 210 again through the liquid inlet 220 to neutralize the liquid temperature. Before this, the user can obtain a certain amount of liquid at a set temperature without the need for reheating. Of course, it can also be heated according to the user's needs.

[0070] Furthermore, if Figures 1 to 3As shown, the liquid inlet 220 is arranged at the bottom of the side wall of the inner container cover 20. This is beneficial for the liquid to enter the heating chamber 210 through the liquid inlet 220 when there is less liquid in the container body 10.

[0071] Furthermore, if Figures 1 to 3 As shown, an air outlet 230 is provided at the top of the inner liner cover 20, and the height of the air outlet 230 is higher than the rated liquid level height of the container body 10. On the one hand, it is convenient for exhaust. On the other hand, the high position of the air outlet 230 can prevent the liquid outside the inner liner cover 20 from entering the heating chamber 210 through the air outlet 230, thereby causing the relatively small heating chamber 210 surrounded by the inner liner cover 20 to fail.

[0072] Furthermore, in some embodiments, the volume of the heating chamber 210 is less than one-half of the volume of the container body 10. The smaller the volume of the heating chamber 210, the faster the liquid inside it is heated to the set temperature. Therefore, the volume of the heating chamber 210 is designed to be less than half of the volume of the container body 10. Compared with the heating component 30 directly heating the liquid in the entire container body 10, the heating time can be shortened, so that the user can obtain the liquid at the set temperature faster, thereby improving the user experience.

[0073] In some embodiments, the volume of the heating chamber 210 accounts for less than one third of the volume of the container body 10. The smaller volume of the heating chamber 210 can greatly shorten the heating time, so that the user can obtain the liquid of the set temperature more quickly.

[0074] As an example, the volume of the heating chamber 210 occupies less than one quarter of the volume of the container body 10 .

[0075] For example, the volume of the heating chamber 210 accounts for one fifth of the volume of the container body 10. When the volume of the container body 10, the amount of water in the container body 10 and other parameters are the same, the heating time with and without the inner liner cover 20 is compared. In the related art, the heating component 30 directly heats the water in the entire container body 10, and the heating time to reach the predetermined temperature is T, while in this embodiment, only one fifth of the volume of water needs to be heated, and the heating time to reach the predetermined temperature is about one quarter T, which greatly shortens the heating time, so that the user can quickly drink water at the desired temperature.

[0076] In a specific application, after water is added to the container body 10, there is water inside and outside the inner liner cover 20 and a balanced state is reached. When the user wants to boil water, the corresponding temperature is selected through the display operation component of the liquid heating device. The bottom of the heating component 30 is provided with a temperature probe 90. After comparing the temperature detected by the temperature probe 90 with the corresponding temperature set by the user, the heating component 30 is heated. Due to the presence of the inner liner cover 20, most of the heat of the heating component 30 will be concentrated to quickly heat the water in the inner liner cover 20, and the water can quickly reach the desired temperature. After the water temperature rises, steam will be discharged through the air outlet 230 at the top of the inner liner cover 20.

[0077] For another example, the volume of the heating chamber 210 accounts for one tenth of the volume of the container body 10 .

[0078] Of course, the smaller the volume of the heating chamber 210, the less time it takes for the liquid inside to reach the set temperature. However, if the volume of the heating chamber 210 is too small, it is not possible to provide the user with an appropriate amount of liquid at the set temperature. Therefore, further, in some embodiments, the volume of the heating chamber 210 is greater than or equal to 200 ml and less than or equal to 500 ml.

[0079] The capacity of most water containers such as cups or bottles is 500 ml or less. Therefore, the capacity of the heating chamber 210 is between 200 ml and 500 ml. The liquid in the heating chamber 210 heats up quickly and is conducive to meeting the drinking water needs of users.

[0080] Furthermore, in some embodiments, the heating chamber 210 has a guide channel (not shown in the figure) connected to the liquid inlet 220 , and the guide channel is used to extend the flow path of the liquid from the liquid inlet 220 to the liquid outlet 110 .

[0081] In these embodiments, the flow path of the liquid from the liquid inlet 220 to the liquid outlet 110 is extended by using the diversion channel. When the liquid in the inner liner cover 20 is heated to the set temperature and flows out from the liquid outlet 110, the diversion channel can delay the unheated liquid in the container body 10 from quickly entering the inner liner cover 20 and flowing toward the liquid outlet 110. During this period, it is beneficial for the liquid at the set temperature in the inner liner cover 20 to enter the liquid outlet 110 more and preferentially, thereby increasing the amount of liquid at the set temperature that the user can quickly obtain.

[0082] In addition, since the flow path from the liquid in the container body 10 to the liquid outlet 110 is extended, when the heating component 30 is constantly heating, the corresponding design is beneficial for heating this part of the liquid to the set temperature before it flows into the liquid outlet 110, which can further increase the amount of liquid at the set temperature that the user can quickly obtain.

[0083] As an example, the flow guide channel extends along the circumference of the inner liner cover 20, so that the liquid introduced from the liquid inlet 220 can flow circumferentially along the inner side wall of the inner liner cover 20. Specifically, the flow guide channel can extend roughly along the circumferential direction of the inner liner cover 20, so that the liquid flows roughly along the inner side wall of the inner liner cover 20 after entering the heating chamber 210, and can be away from the liquid outlet 110 roughly located at the center of the bottom wall of the container body 10, greatly extending the flow path of the liquid from the liquid inlet 220 to the liquid outlet 110.

[0084] As an example, the guide channel extends in a spiral shape, with one end of the guide channel connected to the liquid inlet 220 and the other end connected to the liquid outlet 110. The flow path of the liquid from the liquid inlet 220 to the liquid outlet 110 is also greatly extended. In the process of the liquid in the heating chamber 210 reaching the set temperature and flowing out from the liquid outlet 110, even if the liquid in the container body 10 enters the heating chamber 210 through the liquid inlet 220, it needs to flow along the spiral guide channel and perform heat exchange. During this period, most of the liquid at the set temperature near the liquid outlet 110 in the guide channel can flow out from the liquid outlet 110 first, which is conducive to increasing the amount of liquid at the set temperature that the user can quickly obtain.

[0085] The guide channel may extend in a variety of directions, which are not listed here one by one.

[0086] As an example, the flow guide channel is enclosed by a flow guide pipe, which has a simple structure and is easy to process. The flow guide pipe can be fixed on the inner liner cover 20, and one end is connected to the liquid inlet 220.

[0087] As an example, a guide rib is provided on the inner side of the inner liner cover 20 or the bottom wall of the container body 10, and the guide rib, the inner wall of the inner liner cover 20, and the bottom wall of the container body 10 together enclose a guide channel. The structure is simple and convenient for processing. In addition, when the guide rib is provided on the inner wall of the inner liner cover 20, there is no need to provide a protruding guide rib on the bottom wall of the container body 10, which facilitates cleaning of the container body 10.

[0088] For example, the guide ribs divide the heating chamber 210 into a spiral guide channel. Or there are multiple guide ribs, which divide the heating chamber 210 into a wave-shaped guide channel that fluctuates up and down. The number and shape of the guide ribs are not limited to the above examples, and are not listed here one by one.

[0089] Furthermore, in some embodiments, Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6As shown, the outer edge of the heating component 30 does not exceed the bottom edge of the inner shell 20. Here, the outer edge of the heating component 30 is located on the inner side of the bottom edge of the inner shell 20 in the horizontal direction, so that the heating component 30 can concentrate on heating the liquid in the inner shell 20 and avoid heat dispersion.

[0090] The heating component 30 includes a heating pipe 310 . The bottom wall of the container body 10 is usually made of a heat-conducting material, so the heating pipe 310 can be directly arranged on the bottom wall of the container body 10 .

[0091] Or Figure 1 , Figure 2 , Figures 4 to 6 As shown, the heating component 30 includes a heat conducting plate 320 and a heating pipe 310 located on the lower surface of the heat conducting plate 320. The heating pipe 310 can heat the liquid in the inner liner cover 20 through the heat conducting plate 320 and the bottom wall of the container body 10.

[0092] Regarding the connection method between the inner shell 20 and the container body 10, further, in some embodiments, such as Figures 1 to 3 As shown, a groove 120 is provided in the middle of the bottom wall of the container body 10, the bottom of the inner tank cover 20 is embedded in the groove 120, the liquid outlet 110 is provided on the bottom wall of the groove 120, and the heating component 30 is provided below the bottom wall of the groove 120 and does not exceed the outer edge of the bottom wall of the groove 120.

[0093] In these embodiments, a groove 120 is provided on the bottom wall of the container body 10, so that the inner liner cover 20 can be accurately installed in the container body 10 by aligning the position of the groove 120, thereby improving assembly efficiency. Moreover, the heating component 30 is arranged below the groove bottom wall of the groove 120, and the distance from the non-recessed portion of the bottom wall of the container body 10 is increased, and the heat can be transferred to the groove side wall of the groove 120 to heat the liquid in the inner liner cover 20, which is conducive to concentrating the heat generated by the heating component 30 into the heating chamber 210, thereby improving heating efficiency.

[0094] Furthermore, in some embodiments, the bottom of the inner liner cover 20 is welded to the bottom wall of the container body 10. The inner liner cover 20 and the container body 10 are firmly connected, and the two are sealed together, thereby preventing the liquid outside the inner liner cover 20 from entering the heating chamber 210 through the gap between the inner liner cover 20 and the bottom wall of the container body 10.

[0095] Furthermore, in some embodiments, the inner liner cover 20 is detachable and placed in the container body 10. When the inner liner cover 20 needs to be cleaned, the inner liner cover 20 can be taken out from the container body 10 for cleaning, which is convenient for cleaning. When the container body 10 needs to be cleaned, the inner liner cover 20 can also be taken out, which is convenient for cleaning the inside of the container body 10, avoiding the inconvenience of cleaning due to the obstruction or interference of the inner liner cover 20, and avoiding the accumulation of impurities at the bottom corners of the inner liner cover 20. In addition, when not needed, the inner liner cover 20 can also be taken out, so that there is enough space in the container body 10 to accommodate other liquids or ingredients to be heated.

[0096] In some embodiments, Figure 4 and Figure 5 As shown, a magnetic member 50 is disposed on the lower surface of the bottom wall of the container body 10 , and the magnetic member 50 is used to adsorb the inner liner cover 20 on the bottom wall of the container body 10 .

[0097] In this embodiment, the inner liner cover 20 is fixed to the bottom wall of the container body 10 by magnetic attraction. On the one hand, the inner liner cover 20 can be tightly fitted on the bottom wall of the container body 10 to prevent the liquid outside the inner liner cover 20 from entering the heating chamber 210 in large quantities through the gap between the inner liner cover 20 and the bottom wall of the container body 10. On the other hand, it is convenient to take and put the inner liner cover 20. It can be taken out by simply overcoming the magnetic attraction and pulling the inner liner cover 20 outward. When the inner liner cover 20 is placed in the container body 10, the magnetic part 50 can rely on the magnetic attraction to guide the inner liner cover 20 to move to the specified position, which is conducive to the correspondence between the heating component 30 and the inner liner cover 20. Moreover, under the influence of the magnetic attraction, the inner liner cover 20 can be stably installed in the container body 10 without being easily moved. In addition, the magnetic part 50 is located on the lower surface of the bottom wall of the container body 10, has a simple structure, will not affect the internal structure of the container body 10, and does not have the risk of water leakage.

[0098] As an example, Figure 4 and Figure 5 As shown, a groove 120 is provided in the middle of the bottom wall of the container body 10, and the heating component 30 is arranged below the bottom wall of the groove 120 and does not exceed the outer edge of the bottom wall of the groove 120; the bottom of the inner tank cover 20 has a flange structure 260 extending outward, and the flange structure 260 is built on the bottom wall surface of the container body 10 at the periphery of the groove 120, and the magnetic part 50 is arranged at the periphery of the groove 120, which is used to adsorb the flange structure 260 on the bottom wall of the container body 10.

[0099] The magnetic member 50 may be a magnetic ring, disposed below the bottom wall of the container body 10 and distributed circumferentially around the groove 120. The magnetic member 50 may also be in block shape and the number is at least two, and at least two magnetic members 50 are distributed circumferentially around the groove 120 at intervals.

[0100] By providing the groove 120 on the bottom wall of the container body 10, the heating component 30 is provided below the bottom wall of the groove 120, and the magnetic component 50 is provided on the periphery of the groove 120 to avoid the heating component 30, it is possible to prevent the magnetism of the magnetic component 50 from being affected by the high temperature of the heating component 30 and becoming ineffective. Specifically, the heat generated by the heating component 30 needs to pass through the bottom wall and the side wall of the groove 120 to continue to be transferred outward to the magnetic component 50, and the bottom wall and the side wall of the groove 120 will first perform heat exchange with the liquid in the heating chamber 210, and then continue to transfer heat outward, and the heat transferred out is very small, so the probability of failure of the magnetic component 50 can be effectively reduced.

[0101] In addition, if Figure 4 and Figure 5 As shown, the bottom of the inner liner cover 20 has a flange structure 260 extending outward, and the flange structure 260 cooperates with the magnetic member 50 to increase the magnetic attraction area, which is conducive to the stable installation of the inner liner cover 20 in the container body 10 without movement.

[0102] In other embodiments, Figure 6 As shown, the liquid heating device also includes: a container cover 40, which is covered at the top opening of the container body 10; a stabilizing structure 60, which is arranged at the bottom of the container cover 40 or the top of the inner liner cover 20, and the stabilizing structure 60 is provided with air holes. The container cover 40 presses the inner liner cover 20 against the bottom wall of the container body 10 through the stabilizing structure 60.

[0103] In these embodiments, when the container cover 40 is closed on the container body 10, the inner liner cover 20 is pressed against the bottom wall of the container body 10 by the stabilizing structure 60 below. Even during the heating process, the inner liner cover 20 will not move in the container body 10, which is beneficial for the corresponding distribution of the heating cavity 210 and the heating component 30 up and down.

[0104] Furthermore, the bottom of the inner liner cover 20 has a first elastic pad (not shown in the figure), and the inner liner cover 20 contacts the bottom wall of the container body 10 through the first elastic pad. On the one hand, it can prevent the inner liner cover 20 and the bottom wall of the container body 10 from being worn due to rigid friction, and on the other hand, it can make the inner liner cover 20 and the bottom wall of the container body 10 relatively sealed, and prevent the liquid outside the inner liner cover 20 from entering the heating chamber 210 in large quantities through the gap between the inner liner cover 20 and the bottom wall of the container body 10.

[0105] Based on the situation that the stabilizing structure 60 is arranged at the bottom of the container cover 40, a second elastic pad (not shown in the figure) is arranged at the bottom of the stabilizing structure 60 or the top of the inner container cover 20, and the stabilizing structure 60 is in contact with the inner container cover 20 through the second elastic pad.

[0106] Based on the situation that the stabilizing structure 60 is arranged on the top of the inner container cover 20, the top of the stabilizing structure 60 or the bottom of the container cover 40 has a third elastic pad (not shown in the figure), and the container cover 40 contacts the stabilizing structure 60 through the third elastic pad. Rigid friction can be avoided and wear can be reduced.

[0107] Regarding the specific structure of the inner shell 20, further, in some embodiments, as Figures 1 to 6 As shown, the inner liner cover 20 includes a hollow cover body 240 and a hollow air column 250. The hollow cover body 240 is in the shape of a trumpet with openings at the top and bottom. The larger opening of the trumpet faces the bottom of the container body 10. The liquid inlet 220 is arranged at the bottom of the side wall of the hollow cover body 240. The hollow air column 250 is connected to the top opening of the hollow cover body 240 and extends vertically upward. The top opening of the hollow air column 250 is configured as an air outlet 230.

[0108] The inner liner cover 20 has a simple structure, and the trumpet-shaped hollow cover body 240 has the characteristics of being distributed over a large area corresponding to the heating component 30 and having a small capacity, which is conducive to quickly heating the liquid in the heating chamber 210 to a set temperature. In addition, the hollow air column 250 has a small volume, which is convenient for exhaust. When the inner liner cover 20 and the container body 10 are detachably connected, it is also convenient for the user to hold the hollow column to take and place the inner liner cover 20.

[0109] Furthermore, in some embodiments, Figure 1 , Figure 3 and Figure 6 As shown, the liquid heating device further includes a housing 70 and a pump body 80 disposed in the housing 70, the housing 70 is provided with a water outlet 710, the container body 10 is disposed in the housing 70, and the pump body 80 is connected with the liquid outlet 110 and the water outlet 710 through a pipeline 810, so as to pump liquid to the water outlet 710. The automatic liquid discharge function of the liquid heating device is realized.

[0110] Further, in some embodiments, the liquid heating device is an electric thermos. Of course, the liquid heating device can also be an electric kettle, a health kettle or other drinking water equipment, a beverage machine, etc.

[0111] Although the embodiments of the present invention have been described in detail above, those skilled in the art may make various modifications and variations to the embodiments of the present invention without departing from the spirit and scope of the present invention. It should be understood that, in the opinion of those skilled in the art, these modifications and variations will still fall within the spirit and scope of the embodiments of the present invention as defined in the claims.
