[0039] Electric thermos can boil water for users to drink, but the boiled water cannot be drunk or used immediately. It takes some time for the water to cool down to a certain temperature before it is suitable for drinking and making milk powder, etc. This requires users to spend a lot of time waiting. It takes about 10 hours for a 5L electric thermos to cool down from boiling to 45℃ naturally; if the lid is opened for cooling, there is a possibility that the boiled water will be contaminated.

[0040] In order to solve the above problems, the utility model provides a liquid heating container. Figure 1 A schematic diagram of a partial structure of an embodiment of a liquid heating container provided by the utility model; Figure 2 for Figure 1 A schematic cross-sectional view of a liquid heating container; Figure 3 for Figure 1 A is an enlarged schematic diagram.

[0041] See also Figure 1 to Figure 2The liquid heating container 100 includes a main body 1 and an air supply device 2. The main body 1 includes a shell 11 and an inner tank 12 arranged in the shell 11. The shell 11 is provided with an air inlet 11a and an air outlet 11b. The direction of the air inlet 11a is inclined with respect to the center line of the inner tank 12; the air supply device 2 is used for supplying air from the air inlet toward the air inlet 11a to blow air to the inner tank 12 for heat dissipation.

[0042] It can be understood that the air inlet 11a can be an air inlet hole opened on the shell 11 and penetrating the wall thickness of the shell 11, and the air outlet direction defined by the hole wall of the air inlet hole is at an angle to the center line of the inner liner 12; in order to make the air supply angle more directional, the air supply direction of the air supply device 2 is set at an angle to the center line of the inner liner 12; it can also be that an air supply duct is formed on the outer peripheral wall of the shell 11, and the extension direction of the air supply duct is set at an angle to the center line of the inner liner 12; of course, the method of making the air inlet direction at an angle to the center line of the inner liner 12 is not limited to the above example, and technical personnel in the relevant field may make other changes under the inspiration of the technical essence of the embodiments of this specification, but as long as the functions and effects achieved are the same or similar to the embodiments of this specification, they should be covered within the protection scope of the embodiments of this specification.

[0043] In order to make the air supply path longer, the air outlet 11b can be set on the leeward side away from the air inlet 11a, that is, when the air inlet 11a is facing upward, the air outlet 11b is set at a position close to the bottom side of the shell 11; when the air inlet 11a is facing downward, the air outlet 11b is set at a position close to the upper side of the shell 11.

[0044] It should be noted that the air on the surface of the inner liner 12 is taken away due to the oblique blowing, and fresh air is brought into contact with the surface of the object. This can increase the contact area between the object and the air, promote heat transfer and heat dissipation. And the airflow formed by the oblique blowing can enhance the convective transfer of heat. The airflow takes away the hot air on the surface of the inner liner 12 and replaces it with cooler air, thereby speeding up the heat transfer. Compared with the airflow blowing vertically, a thin boundary layer will be formed on the surface of the object. The flow of this layer of air enhances convective heat transfer, which can effectively take away the hot air and avoid remaining around the object to form a relatively static air layer, which hinders the transfer of heat.

[0045] In the technical solution provided by the utility model, an annular cavity a is defined between the shell 11 and the liner 12, and an air inlet 11a and an air outlet 11b connected to the cavity a are provided on the shell 11, and the air supply device 2 is used to supply air to the air inlet 11a to blow air and dissipate heat to the liner 12. Because the direction of the air inlet 11a is inclined with respect to the center line of the liner 12, the wind from the air inlet 11a blows at a certain angle relative to the liner 12. Toward the inner tank 12, the area for direct heat exchange with the inner tank 12 is larger, and the difference in water temperature stratification is reduced. When the airflow flows from the air outlet 11b into the cavity a, it first flows in a direction away from the air outlet 11b, and then is reflected by the inner wall surface of the cavity a, and then flows to the air outlet 11b. The airflow continuously exchanges heat with the inner tank 12 on the way to the air outlet 11b, and can have a longer heat exchange path, so that the inner tank 12 can be cooled quickly.

[0046] In this embodiment, the air inlet 11a and the air outlet 11b are close to the same side in the height direction of the shell 11. It should be noted that the same side close to the height direction of the shell 11 may be that the air inlet 11a and the air outlet 11b are arranged on the lower side of the middle part of the shell 11; or the air inlet 11a and the air outlet 11b are arranged on the upper side of the middle part of the shell 11; or the air inlet 11a is arranged at the bottom of the shell 11, and the air outlet 11b is arranged on the lower side of the middle part of the shell 11; or the air inlet 11a is arranged at the top of the shell 11, and the air outlet 11b is arranged on the upper side of the middle part of the shell 11, but it is not necessarily that the air inlet 11a and the air outlet 11b are arranged on the top or bottom of the shell 11.

[0047] In this way, the air inlet 11a and the air outlet 11b are placed close to the same side of the shell 11 in the height direction. The airflow flowing into the air inlet 11a moves in the direction away from the air outlet 11b and then turns back to the air outlet 11b. The flow path of the airflow is close to the height distance of the two shells 11, and the heat exchange path of the airflow is longer.

[0048] Furthermore, in order to ensure the safety of the user, in this embodiment, the air inlet 11a and the air outlet 11b are arranged near the bottom side of the shell 11. It should be noted that the liquid heating container 100 includes a cover body covering the opening of the inner pot 12, and generally the opening of the inner pot 12 is arranged at the upper end, so that the air inlet 11a and the air outlet 11b are arranged near the bottom side of the shell 11, and the high-temperature airflow after heat exchange is discharged from the air outlet 11b on the bottom side, so as to avoid the user being scalded by the high-temperature airflow when opening the cover to use water.

[0049] Furthermore, the air inlet 11a and the air outlet 11b are disposed on opposite sides of the housing 11 in the circumferential direction thereof. In addition, the air inlet 11a and the air outlet 11b are disposed close to the bottom side of the housing 11, and the airflow entering from the air inlet 11a needs to flow back to the air outlet 11b located at the bottom of the housing 11 after being blown out upwardly. Compared with disposing the air inlet 11a and the air outlet 11b on the same side, the airflow has a longer heat exchange path.

[0050] Further, in this embodiment, the direction of the air inlet 11a is set at an acute angle to the center line of the inner liner 12, and the angle between the direction of the air inlet 11a and the center line of the inner liner 12 is greater than or equal to 15° and less than or equal to 75°. When the angle range is between 15° and 75°, the angle within this range can make the airflow interact with the surface of the object normally, increase the contact area and convection effect, thereby improving the heat dissipation efficiency. Preferably, the angle between 30 and 45 degrees is the best effect.

[0051] In this embodiment, a cavity a connecting the air inlet 11a and the air outlet 11b is defined between the shell 11 and the inner liner 12, and a partition 3 is provided between the shell 11 and the inner liner 12, and the partition 3 is used to divide the cavity a into two sub-cavities 1a, the air inlet 11a is formed in one of the sub-cavities 1a, and the air outlet 11b is formed in the other sub-cavity 1a; the two sub-cavities 1a are connected. In this way, the airflow entering the air inlet 11a needs to pass through the connecting channel connecting the two sub-cavities 1a, and then flow through the air outlet 11b, so that the airflow can fully exchange heat with the cavity walls of the two sub-cavities 1a, thereby taking away heat and achieving efficient cooling.

[0052] It should be noted that the partition 3 can be two convex ribs protruding from the inner wall of the shell 11, and the side end surfaces of the two convex ribs abut against the outer peripheral wall of the inner liner 12, so as to divide the cavity a into two sub-cavities 1a.

[0053] It should also be noted that the two sub-cavities 1a are connected, and a connecting portion may be provided on the partition 3, or a connecting portion may be provided on the shell 11 or even on the inner tank 12. The specific design can be based on actual conditions, and the embodiments of this specification do not limit this.

[0054] In this embodiment, the two sub-cavities 1a are connected at positions close to the upper and lower ends. It can be understood that when the air inlet 11a is set at a position close to the bottom side of the shell 11, the channel connecting the two sub-cavities 1a can be set at a position close to the upper side of the two sub-cavities 1a, and the air outlet 11b is set at a position close to the bottom side of the shell 11; when the air inlet 11a is set at a position close to the upper side of the shell 11, the channel connecting the two sub-cavities 1a can be set at a position close to the bottom side of the two sub-cavities 1a, and the air outlet 11b is set at a position close to the upper side of the shell 11; in this way, the air inlet 11a is far away from the connected position, so that the heat exchange path of the airflow can be longer, and the heat exchange path lengths in the two sub-cavities 1a are basically the same, and the heat exchange efficiency on both sides of the corresponding inner tank 12 is basically the same.

[0055] Specifically, in this embodiment, the air inlet 11a and the air outlet 11b are arranged near the bottom side of the housing 11, and the two sub-cavities 1a are connected at a position near the upper end; the partition 3 extends in the height direction, and the air inlet 11a is arranged to be tilted upward. In this way, the air inlet 11a and the air outlet 11b are arranged near the bottom side of the housing 11 to ensure the safety of the user, and the two sub-cavities 1a are connected at a position near the upper end, so that the airflow is from bottom to top and then from top to bottom, making the heat exchange path the longest.

[0056] It should be noted that, in addition to being configured as axial ribs extending up and down, the partition portion 3 may also be configured as convex ribs extending in a straight line, or as S-shaped convex ribs. Of course, other possible shapes may also be used, and the specific shapes may be determined based on actual conditions, and the embodiments of this specification do not limit this.

[0057] In order to enable the user to know the water temperature of the inner tank 12 in time, in the present embodiment, the liquid heating container 100 also includes a temperature measuring device 4, and the temperature measuring device 4 is used to measure the temperature of the sub-cavity 1a having the air outlet 11b. Because the sub-cavity 1a having the air outlet 11b is located in the second half of the entire heat exchange path, the temperature in the sub-cavity 1a can better reflect the actual water temperature of the inner tank 12. Therefore, the temperature measuring device 4 can measure the water temperature more accurately.

[0058] In this embodiment, the temperature measuring device 4 is disposed close to the air outlet 11b. The temperature measuring device 4 is far away from the air supply device 2, and the measured temperature is more accurate.

[0059] Specifically, in this embodiment, the shell 11 is penetrated by a first air supply channel 1c, and the extension direction of the first air supply channel 1c is set at an acute angle with the center line of the inner liner 12, and the first air supply channel 1c forms the air inlet. In this way, when the air supply device 2 blows air from the air inlet 11a toward the inner liner 12, the airflow flows along the extension direction of the first air supply channel 1c, and finally dissipates the heat of the inner liner in a direction that is at an acute angle to the center line of the inner liner 12.

[0060] In this embodiment, the air supply device 2 includes a fan, and the fan is preferably an axial flow fan. The air outlet of the fan is arranged toward the air inlet 11a, and the axis of the fan is arranged in parallel with the extension direction of the first air supply channel 1c. In this way, the air outlet direction of the fan is consistent with the extension direction of the first air supply channel 1c, so as to avoid the airflow blown by the fan changing direction when flowing through the first air supply channel 1c and causing airflow turbulence. The liquid heating container 100 also includes a mounting bracket fixedly connected to the shell 11, and the mounting bracket is used to mount the fan.

[0061] Specifically, in the present embodiment, the liquid heating container 100 further includes an electric coupling component 5 and an annular shielding portion 6, wherein the electric coupling component 5 is disposed between the inner pot 12 and the shell 11; the annular shielding portion 6 is disposed between the inner pot 12 and the shell 11, and is sleeved on the periphery of the electric coupling component 5. In this way, the annular shielding portion 6 can block the airflow from flowing toward the electric coupling component 5, thereby preventing the electric coupling component 5 from being affected by the airflow. The temperature measuring device 4 can be a temperature probe disposed near the electric coupling component 5. With such a configuration, all electronic components that need to be connected to a power source can be disposed in the annular shielding portion 6, thereby making the overall layout reasonable and compact.

[0062] Furthermore, a water inlet is provided on the inner tank 12, and the liquid heating container 100 also includes a water outlet seat 7, and a water inlet pipe 8 which can be connected with the water inlet is provided on the water outlet seat 7. In this way, when the main body 1 is installed on the water outlet seat 7, the water inlet pipe 8 can be connected with the water inlet on the inner tank 12, so as to supply water to the inner tank 12.

[0063] Furthermore, in this embodiment, the main body 1 is detachably mounted on the water outlet seat 7 , and the air supply device 2 is disposed on the water outlet seat 7 . When the main body 1 is removed, the user can add water to the inner tank 12 by himself without relying on the water inlet pipe 8 .

[0064] Specifically, in order to ensure the overall appearance of the water outlet seat 7 and the shell, in this embodiment, the water outlet seat 7 has an installation cavity b, and the air supply device 2 is arranged in the installation cavity b. In order to facilitate the airflow to be driven by the air supply device 2, an air inlet 7a and an air outlet 7b are arranged on the installation cavity b, and the air outlet 7b is connected to the air inlet 11a. In this way, the air supply device 2 is arranged in the installation cavity b, so that the air supply device 2 can be inside the water outlet seat 7. On the one hand, it can prevent dust from entering and ensure the appearance of the water outlet seat 7. On the other hand, when the air supply device 2 is working, the airflow can flow from the air inlet 7a to the air outlet 7b, and finally blow to the air inlet 11a, forming a stable airflow direction inside the water outlet seat 7.

[0065] Specifically, in order to enable the air supply device 2 to maintain the stability of the direction of the airflow and reduce wind resistance during the air supply process, in the present embodiment, the shell is provided with a first air supply channel 1c forming the air inlet; the water outlet seat is provided with a second air supply channel 7c, and the second air supply channel 7c forms the air outlet 7b. When the main body is installed to the water outlet seat, the second air supply channel 7c is aligned with and connected to the first air supply channel 1c, and the extension direction of the second air supply channel 7c is parallel to the extension direction of the first air supply channel 1c. In this way, when the airflow flows through the first air supply channel 1c and the second air supply channel 7c, the wind resistance is small.

[0066] Furthermore, in this embodiment, the liquid heating container further comprises a first grille 91, which is arranged in the first air supply channel 1c; and / or the liquid heating container further comprises a second grille 92, which is arranged in the second air supply channel 7c. In this way, by providing the grilles, when the main body and the water outlet seat are disassembled for use, it is avoided that too large openings are formed in the first air supply channel 1c and the second air supply channel 7c, and the first grille 91 and the second grille 92 can ensure the passage of air flow while also ensuring the integrity of the appearance of the shell and the water outlet seat.

[0067] Specifically, in a specific embodiment, the liquid heating container 100 includes an electric thermos. It should be noted that the electric thermos is usually used to heat and keep water warm. The electric thermos also includes a heating element, a temperature control device and a heat preservation layer. The user can pour water into the electric thermos and then heat the water temperature by plugging it in. Once the water reaches the set temperature, the temperature control device will automatically turn off the heating element to keep the water temperature unchanged. In order to facilitate users to drink the water quickly after it boils, the air supply device 2 supplies air to the air inlet to blow air to the inner tank to dissipate heat. The wind from the air inlet blows toward the inner tank at a certain angle relative to the inner tank, so that the area of ​​direct heat exchange with the inner tank is larger, which is convenient for rapid cooling.

[0068] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
