Description

Technical Field

[0001] This application relates to the field of household appliances, and more particularly to a liquid heating container. Background Technology

[0002] Existing liquid heating containers typically have glass windows to allow users to observe the liquid level. However, due to the complex installation structure of the glass window and the obstruction of view by other components of the container, the glass window is not convenient for users to observe when the liquid level is low. Utility Model Content

[0003] This application provides a liquid heating container that solves the problem in the prior art where transparent windows make it inconvenient to observe low liquid levels inside the container.

[0004] This application provides a liquid container, including a control board; an inner liner for holding liquid; a water outlet pipe including a first conductive pipe, a second conductive pipe, and an insulating pipe, wherein along the height direction of the liquid heating container, both ends of the insulating pipe are respectively connected to the first conductive pipe and the second conductive pipe, and the end of the first conductive pipe away from the insulating pipe is connected to the inner liner; a first conductive element is installed on the outer wall of the first conductive pipe and is electrically connected to the control board; a second conductive element is installed on the outer wall of the second conductive pipe and is electrically connected to the control board.

[0005] In the above scheme, when the user is not taking water, the outlet pipe and the inner tank form a communicating vessel structure, meaning the liquid level in the outlet pipe is the same as the liquid level in the inner tank. When the user is not taking water, if the liquid level in the outlet pipe exceeds the top of the insulating tube and is located inside the second conductive tube, the first and second conductive components can be connected through the liquid in the outlet pipe and the first and second conductive tubes. At this time, a closed circuit can be formed between the first and second conductive components and the control board, and the controller on the control board (e.g., a microcontroller) can receive the corresponding signal. If the liquid level in the outlet pipe does not exceed the top of the insulating tube, the first and second conductive components are in an open insulation state. At this time, an open circuit is formed between the first and second conductive components and the control board, and the controller on the control board (e.g., a microcontroller) cannot receive the corresponding signal. The control board can determine the liquid level in the inner tank based on the signal received. When the first conductive element is disconnected from the second conductive element, the control board will not receive the corresponding signal. Based on this, it can be determined that the liquid level in the inner tank is too high as preset, thereby realizing the low liquid level detection function of the liquid heating container and reducing the risk of dry burning of the liquid heating container.

[0006] The liquid heating container provided in this embodiment can determine whether the liquid level in the inner tank is too low by receiving signals from the control board, eliminating the need for visual inspection by the user. This results in more accurate judgments and a better user experience. Furthermore, the elimination of a transparent window on the outer shell simplifies the structure and allows for greater innovation in the appearance and functional layout of the liquid heating container. In this embodiment, the water outlet pipe serves as both the liquid outlet and the liquid level detection pipe, achieving a unified function and eliminating the need for a separate liquid level detection pipe, further simplifying the structure of the liquid heating container. The first and second conductive components are respectively disposed on the outer walls of the first and second conductive tubes, and do not directly contact the liquid, thus not affecting the user's drinking water safety. Moreover, compared to conventional liquid level sensors, the first and second conductive components are not affected by water temperature, resulting in a lower probability of failure and improving the reliability of the liquid level detection results.

[0007] In one possible design, at least a portion of the first conductive tube is located inside the insulating tube; and / or, at least a portion of the second conductive tube is located inside the insulating tube.

[0008] In the above scheme, when at least a portion of the first conductive tube is located inside the insulating tube, it ensures that the water in the first conductive tube flows accurately into the insulating tube without flowing out, reducing the risk of leakage at the connection between the first conductive tube and the insulating tube. Similarly, when at least a portion of the second conductive tube is located inside the insulating tube, it ensures that the water in the insulating tube flows accurately into the second conductive tube without flowing out, reducing the risk of leakage at the connection between the second conductive tube and the insulating tube. Therefore, when at least a portion of both the first and second conductive tubes are located inside the insulating tube, it is beneficial to improve the sealing performance of the outlet pipe and reduce the risk of leakage.

[0009] In one possible design, the inner wall of the insulating tube is provided with a first receiving groove, and the end of the first conductive tube is limited to the bottom wall of the first receiving groove along the length direction of the insulating tube; and / or, the inner wall of the insulating tube is provided with a second receiving groove, and the end of the second conductive tube is limited to the bottom wall of the second receiving groove along the length direction of the insulating tube.

[0010] In the above scheme, when the first conductive tube extends into the insulating tube, its end can be positioned and engaged with the bottom wall of the first receiving groove along the length of the insulating tube. This controls the length of the first conductive tube extending into the insulating tube, reducing the risk of relative movement between the first conductive tube and the insulating tube when the liquid heating container shakes. This ensures that the end of the insulating tube remains at a preset height, improving the installation stability and reliability of the insulating tube, and thus enhancing the accuracy and reliability of the low-level detection function of the liquid heating container. Similarly, when the second conductive tube extends into the insulating tube, its end is positioned and engaged with the bottom wall of the second receiving groove along the length of the insulating tube. This controls the length of the second conductive tube extending into the insulating tube, reducing the risk of relative movement between the second conductive tube and the insulating tube when the liquid heating container shakes, and enhancing the installation stability and reliability of the second conductive tube. Therefore, when the insulating tube is equipped with both a first receiving groove and a second receiving groove, it improves the installation stability of the second conductive tube and the insulating tube, and also enhances the accuracy and reliability of the low-level detection function of the liquid heating container.

[0011] In one possible design, the liquid heating container further includes a first seal, at least a portion of which covers the connection between the first conductive tube and the insulating tube; and / or, the liquid heating container further includes a second seal, at least a portion of which covers the connection between the second conductive tube and the insulating tube.

[0012] In the above solution, the first sealing element can seal the connection between the first conductive tube and the insulating tube, further reducing the risk of water leakage at the connection. Similarly, the second sealing element can seal the connection between the first conductive tube and the insulating tube, further reducing the risk of water leakage at the connection. When both the first and second sealing elements are provided, it is beneficial to further improve the sealing performance of the water outlet pipe and reduce the risk of water leakage from the water outlet pipe.

[0013] In one possible design, the first seal includes a first cover and a second cover, the inner diameter of the first cover being larger than the inner diameter of the second cover, the first cover being used to wrap the connection between the first conductive tube and the insulating tube; the second cover being used to wrap the first conductive tube; and / or, the second seal includes a third cover and a fourth cover, the inner diameter of the third cover being larger than the inner diameter of the fourth cover, the third cover being used to wrap the connection between the second conductive tube and the insulating tube; the fourth cover being used to wrap the second conductive tube.

[0014] In the above scheme, the first covering part is used to wrap the connection between the first conductive tube and the insulating tube, serving as a seal. The second covering part is used to wrap the first conductive tube, and its inner wall can fit against the outer wall of the first conductive tube, which not only further improves the sealing effect of the first seal, but also improves the installation stability of the first seal and reduces the risk of the first seal falling off. Similarly, the third covering part is used to wrap the connection between the second conductive tube and the insulating tube, serving as a seal. The fourth covering part is used to wrap the second conductive tube, and its inner wall can fit against the outer wall of the second conductive tube, which not only further improves the sealing effect of the second seal, but also improves the installation stability of the second seal and reduces the risk of the second seal falling off. When the first seal is provided with the first and second covering parts, and the second seal is provided with the third and fourth covering parts, it is beneficial to further improve the sealing performance of the water outlet pipe, thereby reducing the risk of water leakage from the water outlet pipe.

[0015] In one possible design, the first conductive element is a metal clamp, which is sleeved on the first conductive tube; and / or, the second conductive element is a metal clamp, which is sleeved on the second conductive tube.

[0016] In the above scheme, firstly, metal clamps can meet the conductivity requirements; secondly, clamps are inexpensive, simple in structure, and easy to install and disassemble; moreover, the size of the clamps is adjustable to accommodate different sizes of first or second conductive tubes. Therefore, when metal clamps are selected as the first conductive component, it is convenient to adjust the installation position of the first conductive component on the first conductive tube, and also convenient to install and disassemble the first conductive component. Similarly, when metal clamps are selected as the second conductive component, it is convenient to adjust the installation position of the second conductive component on the second conductive tube, and also convenient to install and disassemble the second conductive component. When both the first and second conductive components are metal clamps, it is beneficial to reduce the cost of the liquid heating container and improve the flexibility of the internal structure of the liquid heating container.

[0017] In one possible design, the first conductive tube is located below the inner liner along the height direction of the liquid heating container.

[0018] In the above scheme, the first conductive tube is located below the inner liner, meaning the height of the top of the first conductive tube does not exceed the height of the bottom wall of the inner liner. This ensures that the insulating tube is at a suitable height, avoiding an excessively high preset liquid level due to the top of the insulating tube being too high, which would be detrimental to the low liquid level detection function of the liquid heating container.

[0019] In one possible design, the liquid heating container further includes an indicator light, which is electrically or signal-connected to the control board; when the first conductive element and the second conductive element are disconnected, the control board controls the indicator light to turn on; when the first conductive element and the second conductive element are connected, the control board controls the indicator light to turn off.

[0020] In the above scheme, when the first and second conductive components are disconnected, the control board does not receive the corresponding signal. Based on this, it determines that the liquid level in the inner tank is lower than the preset level. At this time, the control board can output a signal to the indicator light to turn it on, allowing the user to add water to the inner tank or stop heating the liquid, thus preventing the liquid heating container from drying out. When the first and second conductive components are connected, the control board receives the corresponding signal and determines that the liquid level in the inner tank is higher than the preset level. At this time, the control board can output a signal to the indicator light to turn it off, allowing the user to know that water does not need to be added to the inner tank. Therefore, by setting an indicator light, the liquid level in the inner tank can be displayed to the user, achieving an intelligent liquid level reminder effect for the liquid heating container, which improves the user experience.

[0021] In one possible design, the liquid heating container further includes an alarm, which is electrically or signal-connected to the control board; when the first conductive element and the second conductive element are disconnected, the control board controls the alarm to turn on; when the first conductive element and the second conductive element are connected, the control board controls the alarm to turn off.

[0022] In the above scheme, when the first and second conductive components are disconnected, the control board does not receive the corresponding signal. Based on this, it determines that the liquid level in the inner tank is lower than the preset level. At this time, the control board can output a signal to the alarm to activate it, allowing the user to add water to the inner tank or stop heating the liquid, thus preventing the liquid heating container from drying out. When the first and second conductive components are connected, the control board receives the corresponding signal and determines that the liquid level in the inner tank is higher than the preset level. At this time, the control board can output a signal to the alarm to deactivate it, allowing the user to know that adding water to the inner tank is not currently necessary. Therefore, by setting an alarm, the user can be alerted to the liquid level in the inner tank, achieving an intelligent liquid level reminder effect for the liquid heating container, which improves the user experience.

[0023] In one possible design, the liquid heating container further includes an inner shell, and the inner liner is installed inside the inner shell; the outer wall of the inner liner is provided with a limiting protrusion, and the inner wall of the inner shell is provided with a limiting step, and at least a portion of the limiting protrusion overlaps with the limiting step.

[0024] In the above scheme, at least part of the limiting protrusion overlaps with the limiting step. The combination of the limiting protrusion and the limiting step can limit the inner liner, prevent the inner liner from sinking, and prevent the inner liner from shaking inside the inner shell. At the same time, the limiting step can support the limiting protrusion, which helps to improve the installation stability of the inner liner. Attached Figure Description

[0060] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0061] It should be noted that the directional terms such as "upper," "lower," "left," and "right" described in the embodiments of this application are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when it is mentioned that an element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.

[0062] This application provides a liquid heating container, such as... Figure 1 and Figure 2 As shown, the liquid heating container includes an inner liner 1, a water outlet pipe 2, a water outlet 9, and an outer shell 8. The inner liner 1 is installed inside the outer shell 8 and is used to hold liquid. The water outlet pipe 2 is installed in the gap between the inner liner 1 and the outer shell 8, and is connected to the water outlet 9 and the bottom of the inner liner 1 respectively. One end of the water outlet 9 is located inside the outer shell 8 to connect with the water outlet pipe 2, and at least part of the other end extends out of the outer shell 8 to communicate with the outside. The liquid in the inner liner 1 can flow to the outside through the water outlet pipe 2 and the water outlet 9 for the user to drink.

[0063] like Figure 2 As shown, the water outlet pipe 2 specifically includes a first conductive pipe 21, a second conductive pipe 22, and an insulating pipe 23. Along the height direction Z of the liquid heating container, both ends of the insulating pipe 23 are connected to the first conductive pipe 21 and the second conductive pipe 22, respectively. The end of the first conductive pipe 21 away from the insulating pipe 23 is used to connect to the inner liner 1, that is, the first conductive pipe 21 is located below the insulating pipe 23 and the second conductive pipe 22. The liquid heating container also includes a first conductive element 3, a second conductive element 4, and a control board (not shown in the figure). The control board is installed inside the outer shell 8, specifically below the inner liner 1. The first conductive element 3 is installed on the outer wall of the first conductive pipe 21, and the first conductive element 3 leads out a signal line and a DC ground line to achieve electrical connection with the control board. The second conductive element 4 is installed on the outer wall of the second conductive pipe 22, and the second conductive element leads out a signal line and a DC ground line to achieve electrical connection with the control board.

[0064] In this embodiment, when the user is not taking water, the water outlet pipe 2 and the inner tank 1 form a communicating vessel structure, meaning the liquid level in the water outlet pipe 2 is the same as the liquid level in the inner tank 1. When the user is not taking water, if the liquid level in the water outlet pipe 2 exceeds the top of the insulating pipe 23 and is located inside the second conductive pipe 22, the first conductive element 3 and the second conductive element 4 can be connected through the liquid in the water outlet pipe 2 and the first conductive pipe 21 and the second conductive pipe 22. At this time, a closed loop can be formed between the first conductive element 3, the second conductive element 4 and the control board, and the controller on the control board (e.g., a microcontroller) can receive the corresponding signal. If the liquid level in the water outlet pipe 2 does not exceed the top of the insulating pipe 23, the first conductive element 3 and the second conductive element 4 are in an insulated disconnected state. At this time, an open circuit is formed between the first conductive element 3, the second conductive element 4 and the control board, and the controller on the control board (e.g., a microcontroller) cannot receive the corresponding signal. That is, the control board can determine the liquid level in the inner tank 1 based on the signal reception. When the first conductive element 3 and the second conductive element 4 are disconnected, the control board will not receive the corresponding signal. Based on this, it can be determined that the liquid level in the inner tank 1 is too high as the preset liquid level, thereby realizing the low liquid level detection function of the liquid heating container and reducing the risk of dry burning of the liquid heating container.

[0065] The height of the top of the insulating tube 23 is the preset liquid level. When the liquid level in the outlet pipe 2 is lower than the top of the insulating tube 23, the control board does not receive the corresponding signal and can determine that the liquid level in the inner tank 1 is too low. Therefore, the preset liquid level can be changed by adjusting the installation position of the insulating tube 23 in the height direction Z of the liquid heating container, or by adjusting the length of the insulating tube 23 in the height direction Z of the liquid heating container. It can be understood that when the top of the insulating tube 23 is lower than the bottom wall of the inner tank 1, the first conductive element 3 and the second conductive element 4 are only disconnected when there is no water in the inner tank 1. That is, the control board will only make a judgment that the liquid level is too low because it does not receive the corresponding signal when there is no water in the inner tank 1.

[0066] The liquid heating container provided in this embodiment can determine whether the liquid level in the inner tank 1 is too low by receiving signals from the control board, eliminating the need for visual observation by the user. This results in more accurate judgments and a better user experience. Furthermore, the elimination of a transparent window on the outer shell 8 simplifies its structure and allows for greater innovation in the appearance and functional layout of the liquid heating container. In this embodiment, the water outlet pipe 2 serves both as the liquid outlet pipe when water is dispensed from the liquid heating container and as the liquid level detection pipe, achieving a combined effect of outlet and detection pipes. This eliminates the need for a separate liquid level detection pipe, further simplifying the structure of the liquid heating container. The first conductive element 3 and the second conductive element 4 are respectively disposed on the outer walls of the first conductive tube 21 and the second conductive tube 22, and do not directly contact the liquid, thus not affecting the user's drinking water safety. Moreover, compared to conventional liquid level sensors, the first conductive element 3 and the second conductive element 4 are not affected by water temperature, resulting in a lower probability of failure and improved reliability of the liquid level detection results.

[0067] In this embodiment, the first conductive tube 21 can be a metal tube or a graphite tube, or other conductive composite material tube. Similarly, the second conductive tube 22 can be a metal tube or a graphite tube, or other conductive composite material tube. The insulating tube 23 can be a plastic tube.

[0068] In one specific implementation, such as Figure 2 As shown, along the height direction Z of the liquid heating container, the first conductive tube 21 is located below the inner liner 1, meaning the height of the top of the first conductive tube 21 does not exceed the height of the bottom wall of the inner liner 1. This ensures that the insulating tube 23 is at a suitable height, preventing the preset liquid level from being too high due to the top of the insulating tube 23 being too high, which would be detrimental to the liquid heating container's low liquid level detection function.

[0069] Preferably, one end of the first conductive tube 21 connected to the insulating tube 23 extends vertically along the height direction Z of the liquid heating container, while the other parts are arranged horizontally below the inner liner 1 along the radial direction X of the liquid heating container, which helps to save space and improve the space utilization rate inside the liquid heating container.

[0070] In one specific implementation, such as Figure 3 As shown, when at least a portion of the first conductive tube 21 is located inside the insulating tube 23, it can be ensured that the water inside the first conductive tube 21 flows accurately into the insulating tube 23 without flowing out, thus reducing the risk of water leakage at the connection between the first conductive tube 21 and the insulating tube 23.

[0071] Furthermore, a first receiving groove 231 can be provided on the inner wall of the insulating tube 23. When the first conductive tube 21 extends into the insulating tube 23, the end of the first conductive tube 21 can be limited and matched with the bottom wall of the first receiving groove 231 along the length direction of the insulating tube 23, thereby controlling the length of the first conductive tube 21 extending into the insulating tube 23. This reduces the risk of relative movement between the first conductive tube 21 and the insulating tube 23 when the liquid heating container shakes, thereby ensuring that the end of the insulating tube 23 can remain at a preset height. This is beneficial to improving the installation stability and reliability of the insulating tube 23, thereby improving the accuracy and reliability of the low liquid level detection function of the liquid heating container.

[0072] Similarly, such as Figure 4 As shown, when at least a portion of the second conductive tube 22 is located inside the insulating tube 23, it can be ensured that the water inside the insulating tube 23 flows accurately into the second conductive tube 22 without flowing out, thus reducing the risk of water leakage at the connection between the second conductive tube 22 and the insulating tube 23.

[0073] Furthermore, a second receiving groove 232 can be provided on the inner wall of the insulating tube 23. When the second conductive tube 22 extends into the insulating tube 23, the end of the second conductive tube 22 and the bottom wall of the second receiving groove 232 are limited and matched along the length direction of the insulating tube 23, thereby controlling the length of the second conductive tube 22 extending into the insulating tube 23. This reduces the risk of relative movement between the second conductive tube 22 and the insulating tube 23 when the liquid heating container shakes, which is beneficial to improving the installation stability and reliability of the second conductive tube 22.

[0074] Therefore, when at least a portion of the first conductive tube 21 is located inside the insulating tube 23, and at least a portion of the second conductive tube 22 is located inside the insulating tube 23, it is beneficial to improve the sealing performance of the outlet tube 2 and reduce the risk of leakage from the outlet tube 2. When the insulating tube 23 is simultaneously provided with the first receiving groove 231 and the second receiving groove 232, it is beneficial to improve the installation stability of the second conductive tube 22 and the insulating tube 23, and also beneficial to improve the accuracy and reliability of the low liquid level detection function of the liquid heating container.

[0075] In one specific implementation, such as Figure 3 As shown, the liquid heating container also includes a first sealing element 5. At least a portion of the first sealing element 5 wraps around the connection between the first conductive tube 21 and the insulating tube 23, thereby sealing the connection and further reducing the risk of leakage. The first sealing element 5 can be made of silicone or rubber, which not only provides a good seal but also has a certain degree of elasticity, facilitating its installation.

[0076] Specifically, the first sealing element 5 includes a first covering portion 51 and a second covering portion 52, wherein the inner diameter of the first covering portion 51 is larger than the inner diameter of the second covering portion 52. The first covering portion 51 is used to wrap around the connection between the first conductive tube 21 and the insulating tube 23, thereby sealing the connection. The second covering portion 52 is used to wrap around the first conductive tube 21, and its inner wall can fit against the outer wall of the first conductive tube 21. This not only further improves the sealing effect of the first sealing element 5, but also improves the installation stability of the first sealing element 5 and reduces the risk of the first sealing element 5 falling off.

[0077] In one specific implementation, such as Figure 4 As shown, the liquid heating container also includes a second sealing element 6. At least a portion of the second sealing element 6 wraps around the connection between the second conductive tube 22 and the insulating tube 23, thereby sealing the connection and further reducing the risk of leakage. The second sealing element 6 can be made of silicone or rubber, providing not only a good sealing effect but also a certain degree of elasticity, facilitating its installation.

[0078] Specifically, the second sealing element 6 includes a third covering portion 61 and a fourth covering portion 62. The inner diameter of the third covering portion 61 is larger than the inner diameter of the fourth covering portion 62. The third covering portion 61 is used to wrap around the connection between the second conductive tube 22 and the insulating tube 23, thus sealing the connection. The fourth covering portion 62 is used to wrap around the second conductive tube 22, and its inner wall can fit against the outer wall of the second conductive tube 22. This not only further improves the sealing effect of the second sealing element 6, but also improves the installation stability of the second sealing element 6 and reduces the risk of the second sealing element 6 falling off.

[0079] In this embodiment, when the first sealing element 5 and the second sealing element 6 are provided simultaneously, it is beneficial to further improve the sealing performance of the water outlet pipe 2, so as to reduce the risk of water leakage from the water outlet pipe 2.

[0080] When the first sealing member 5 is provided with a first covering part 51 and a second covering part 52, and the second sealing member is provided with a third covering part 61 and a fourth covering part 62, it is beneficial to further improve the sealing performance of the water outlet pipe 2 and reduce the risk of water leakage from the water outlet pipe 2.

[0081] It should be noted that when the second seal 6 is made of insulating material, the first conductive element 3 and the second conductive element 4 can only achieve conductivity when the liquid level in the outlet pipe 2 exceeds the end of the second seal 6. That is, when the second seal 6 is provided, the height of the top of the second seal 6 is the height of the preset liquid level.

[0082] In one specific implementation, such as Figure 2As shown, the first conductive element 3 is a metal clamp, which is sleeved on the first conductive tube 21, and / or the second conductive element 4 is a metal clamp, which is sleeved on the second conductive tube 22.

[0083] First, metal clamps can meet the requirements of conductivity. Second, clamps are inexpensive, simple in structure, easy to install and disassemble, and the size of clamps can be adjusted to fit different sizes of the first conductive tube 21 or the second conductive tube 22.

[0084] Therefore, using a metal clamp as the first conductive element 3 facilitates adjusting its installation position on the first conductive tube 21, and also makes it convenient to install and remove the first conductive element 3. Similarly, using a metal clamp as the second conductive element 4 facilitates adjusting its installation position on the second conductive tube 22, and also makes it convenient to install and remove the second conductive element 4. When both the first conductive element 3 and the second conductive element 4 are metal clamps, it helps to reduce the cost of the liquid heating container and improve the flexibility of the internal structure of the liquid heating container.

[0085] In one specific embodiment, the liquid heating container also includes an indicator light, which is electrically or signal-connected to the control board. When the first conductive element 3 and the second conductive element 4 are disconnected, the control board does not receive a corresponding signal and determines that the liquid level in the inner liner 1 is lower than a preset level. At this time, the control board can output a signal to the indicator light to turn it on, so that the user can add water to the inner liner 1 or stop heating the liquid in the inner liner 1 according to the indicator light's prompt, thus preventing the liquid heating container from drying out. When the first conductive element 3 and the second conductive element 4 are connected, the control board receives a corresponding signal and determines that the liquid level in the inner liner 1 is higher than the preset level. At this time, the control board can output a signal to the indicator light to turn it off, so that the user knows that water does not need to be added to the inner liner 1. Therefore, by setting an indicator light, the liquid level in the inner liner 1 can be indicated to the user, achieving an intelligent liquid level reminder effect for the liquid heating container, which is beneficial to improving the user experience.

[0086] Specifically, a display panel (not shown in the figure) can be provided on the outer shell 8 of the liquid heating container, and indicator lights can be installed on the display panel. The display panel can be located on the front, side, or top surface of the outer shell 8, and this embodiment does not limit this. The display panel can also be provided with various control buttons that are electrically or signal-connected to the control board. The control board can control other electrical components that are electrically or signal-connected to the control board to turn on or off according to the user's operation of the buttons.

[0087] like Figure 2As shown, the liquid heating container also includes a heating assembly 10, which is disposed on the outer bottom wall of the inner liner 1 and is used to heat the liquid in the inner liner 1. The heating assembly 10 can be electrically or signal-connected to the control board. When the first conductive element 3 and the second conductive element 4 are disconnected, the control board does not receive the corresponding signal and determines that the liquid level in the inner liner 1 is lower than the preset liquid level. At this time, the control board can output a signal to the heating assembly 10 to control the heating assembly 10 to turn off. When the first conductive element 3 and the second conductive element 4 are connected, the control board receives the corresponding signal and determines that the liquid level in the inner liner 1 is higher than the preset liquid level. At this time, the control board can output a signal to the heating assembly 10 to control the heating assembly 10 to turn on, thereby achieving the intelligent heating effect of the liquid heating container.

[0088] In one specific embodiment, the liquid heating container also includes an alarm, which is electrically or signal-connected to the control board. When the first conductive element 3 and the second conductive element 4 are disconnected, the control board does not receive a corresponding signal and determines that the liquid level in the inner tank 1 is lower than a preset level. At this time, the control board can output a signal to the alarm to activate it, allowing the user to add water to the inner tank 1 or stop heating the liquid in the inner tank 1 according to the alarm's prompt, thus preventing the liquid heating container from drying out. When the first conductive element 3 and the second conductive element 4 are connected, the control board receives a corresponding signal and determines that the liquid level in the inner tank 1 is higher than the preset level. At this time, the control board can output a signal to the alarm to deactivate it, allowing the user to know that water does not need to be added to the inner tank 1. Therefore, by setting an alarm, the user can be informed of the liquid level in the inner tank 1, achieving an intelligent liquid level reminder effect for the liquid heating container, which is beneficial to improving the user experience.

[0089] Specifically, the alarm can be installed on the display panel to achieve integration of the display panel, or it can be installed in other locations on the surface of the housing 8, or it can be installed inside the housing 8; this embodiment does not impose any limitations on this. The alarm can specifically be a buzzer or other components with audible warning functions.

[0090] In one specific implementation, such as Figure 2 As shown, the liquid heating container also includes an inner shell 7, which is disposed inside the outer shell 8. The inner liner 1 is installed inside the inner shell 7, and the inner shell 7 serves to insulate the water. Figure 5 As shown, the outer wall of the inner liner 1 is provided with a limiting protrusion 11, and the inner wall of the inner shell 7 is provided with a limiting step 71. At least a portion of the limiting protrusion 11 overlaps with the limiting step 71. The cooperation between the limiting protrusion 11 and the limiting step 71 can limit the inner liner 1, prevent the inner liner 1 from sinking, and also prevent the inner liner 1 from shaking inside the inner shell 7. At the same time, the limiting step 71 can support the limiting protrusion 11, which is beneficial to improving the installation stability of the inner liner 1.

[0091] In one specific implementation, such as Figure 6 As shown, the outer casing 8 is equipped with a detachable top cover 81, and the top cover 81 is equipped with a handle 83. The user can install or remove the top cover 81 by using the handle 83 to facilitate adding water to the inner tank 1. In addition, the top cover 81 is also equipped with a steam port 82, through which steam in the inner tank 1 can flow to the outside, thereby balancing the internal and external air pressure of the liquid heating container and improving the safety of the liquid heating container.

[0092] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
