[0028] As Figures 1 to 9 The liquid heater with automatic temperature control shown in the figure, including heating seat 1, with the heating seat 1 is connected with the container 2, for heating the container 2 heating assembly 3, the heating seat 1 is equipped with the electric control assembly 4 connected with the heating assembly 3, for detecting temperature and with the electric control assembly 4 is connected with the sensor 5, for containing the sensor 5 limit chamber 6, the sensor 5 is equipped with temperature detection end 51, the limit chamber 6 is equipped with the first limit chamber opening 61 for the temperature detection end 51 to stretch out, the limit chamber 6 is arranged along the horizontal direction, the limit chamber 6 is equipped with the support part 62 of the sensor 5, the sensor 5 is close to the bottom of the container 2 or the heating assembly 3, to adjust the power of the heating assembly 3 through the electric control assembly 4.

[0029] The utility model discloses a limit chamber limit sensor is set up in horizontal direction, utilizes the support part to stabilize the support sensor, effectively avoids the deformation or failure problem of spare part in traditional temperature measuring assembly because of frequent up and down plug -in and plug -out, when the sensor is close to or contacts the container bottom or heating assembly of liquid heater, will not produce frequent displacement, and the temperature detection end can keep the position fixed, thereby guaranteeing the accuracy of temperature detection.

[0030] Optionally, in some embodiments, the temperature sensor can be set to detect remotely by non-contact, and can also be set to contact the object.

[0031] Specifically, the temperature detection end of the sensor detects the temperature of the container bottom or the heating assembly surface by being close to the container bottom or the heating assembly, using infrared detection, air convection detection and the like.

[0032] Of course, in some embodiments, the temperature detection end of the sensor can contact the container bottom or the heating assembly, and can adjust the power of the heating assembly according to the detected temperature condition through the electric control assembly, so that the liquid heater can realize accurate automatic temperature control function. The heating assembly makes the liquid reach a suitable temperature during the heating process, or maintains the temperature stable during the holding stage, which can rely on the sensor to feedback information in time and be effectively regulated and controlled by the electric control assembly, improve the accuracy of heating and temperature control of the liquid heater, better meet the needs of users for liquid heating use of different temperature drinks, and thus enhance the practicability and user experience of the product.

[0033] In addition, the horizontally arranged limit chamber enables the sensor to be arranged horizontally, which can reduce the displacement in the vertical direction when the sensor contacts the object during the contact process of the container bottom or the heating assembly, and can also reduce the deformation and failure of the temperature measuring assembly during the up and down plug-in and plug-out process, so that the sensor can work normally in a long time high temperature environment, and the service life of the liquid heater is prolonged.

[0034] Compared with the temperature measuring assembly of the prior art which is composed of multiple parts and takes a long time to assemble, the utility model sets the sensor in the limit chamber, does not need to additionally set a bracket or an elastic body, reduces the space occupied by the temperature measuring assembly, effectively reduces the time and labor cost consumed in the assembly process, and improves the production and assembly efficiency.

[0035] Optionally, in some embodiments, the temperature sensor can be set to detect remotely by non-contact, and can also be set to contact the object.

[0031] Specifically, the temperature detection end of the sensor detects the temperature of the container bottom or the heating assembly surface by being close to the container bottom or the heating assembly, using infrared detection, air convection detection and the like.

[0032] Of course, in some embodiments, the temperature detection end of the sensor can contact the container bottom or the heating assembly, and can adjust the power of the heating assembly according to the detected temperature condition through the electric control assembly, so that the liquid heater can realize accurate automatic temperature control function.

[0033] In addition, the horizontally arranged limit chamber enables the sensor to be arranged horizontally, which can reduce the displacement in the vertical direction when the sensor contacts the object during the contact process of the container bottom or the heating assembly, and can also reduce the deformation and failure of the temperature measuring assembly during the up and down plug-in and plug-out process, so that the sensor can work normally in a long time high temperature environment, and the service life of the liquid heater is prolonged.

[0034] Compared with the temperature measuring assembly of the prior art which is composed of multiple parts and takes a long time to assemble, the utility model sets the sensor in the limit chamber, does not need to additionally set a bracket or an elastic body, reduces the space occupied by the temperature measuring assembly, effectively reduces the time and labor cost consumed in the assembly process, and improves the production and assembly efficiency.

[0035] Optionally, in some embodiments, the temperature sensor can be set to detect remotely by non-contact, and can also be set to contact the object.

[0036] Optionally, in some embodiments, the sensor exposed to the opening of the first limiting chamber can be the entire temperature detection end, a temperature detection end occupying a local area of ​​the sensor, or a detection component that integrates other functions and has temperature detection function.

[0037] Specifically, this utility model is applied in the fields of health-preserving kettles, flower teapots, and electric kettles.

[0038] like Figures 7 to 9 The liquid heater with automatic temperature control shown has a heating base 1 with a first connecting part 11 extending from the inner wall of the heating base 1 toward the center of the heating base 1, and a second connecting part 12 located between the first connecting part 11 and the center of the heating base 1. A supporting part 62 is disposed on the second connecting part 12. The lower end surface of the first connecting part 11 is higher than the upper end surface of the supporting part 62. The first connecting part 11 and the supporting part 62 enclose the limiting chamber 6 in the vertical direction.

[0039] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, by using the first connecting part and the supporting part extending from the inner wall of the heating seat towards the center to enclose and form a limiting chamber in the vertical direction, there is no need to add too many external structures to accommodate the sensor. This can make efficient use of the internal space of the heating seat and also helps to make the structure of the entire liquid heater more compact.

[0040] Specifically, the support part is set in the second connecting part, and the sensors can be stably placed in the limiting chamber. The first connecting part can restrict the upward movement of the sensor, and the support part can restrict the downward movement of the sensor, thereby ensuring that the sensor can stably contact the bottom of the container or the heating component, ensuring the accuracy of temperature detection and the normal realization of temperature control function.

[0041] In some embodiments, the lower end face of the first connecting part is higher than the upper end face of the supporting part. The inner wall of the heating seat, the lower end face of the first connecting part, the side wall of the second connecting part, and the upper end face of the supporting part are used to enclose the limiting chamber, so that the limiting chamber forms a space that can fix the sensor, which plays a certain supporting and isolation role for the sensor.

[0042] Furthermore, when assembling the liquid heater, the operator can easily place the sensor into the limiting chamber formed in the horizontal direction between the first connecting part and the second connecting part, and in the vertical direction between the first connecting part and the support part. When inspecting, repairing or replacing, the operator can quickly locate the sensor, thereby saving maintenance time and costs.

[0043] Optionally, in some embodiments, the sensor can be inserted into or removed from the opening of the first limiting chamber.

[0044] In some embodiments, the first connecting portion may be a protrusion with a cavity that extends partially upward, so that the limiting cavity is a defined space, or it may be a protruding structure that extends upward in a ring shape so that the limiting cavity is arranged in a ring shape on the periphery of the inner wall of the heating seat.

[0045] Optionally, in some embodiments, the upper surface of the first connecting portion may be higher than the upper surface of the second connecting portion, or the upper surface of the first connecting portion may be flush with the upper surface of the second connecting portion. When the supporting portion is located below the upper surface of the second connecting portion, the sensor can be fixed and limited as long as the distance between the first connecting portion and the supporting portion in the vertical direction is sufficient for the sensor to extend into.

[0046] like Figures 7 to 9 The liquid heater shown has an automatic temperature control. The first limiting chamber opening 61 is located on the upper side of the second connecting part 12, and the lower side of the limiting chamber 6 has a second limiting chamber opening 63 for the sensor 5 to extend into.

[0047] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, the opening of the first limiting chamber on the upper side of the second connecting part exposes the upper side of the temperature detection end, which facilitates the contact between the bottom of the container or the bottom of the heating assembly and the upper side of the sensor.

[0048] Furthermore, the first limiting chamber opening of the second connecting part and the supporting part are arranged opposite to each other. The second limiting chamber opening on the lower side of the limiting chamber makes it convenient for the installer to insert the sensor from bottom to top into the second limiting chamber opening, and then lock the sensor between the supporting part and the first limiting chamber opening.

[0049] like Figures 2 to 9 The liquid heater with automatic temperature control shown has an upwardly extending flange 13 between the first connecting part 11 and the second connecting part 12. The heating base 1 has a first channel opening 14 located between the inner wall of the heating base 1 and the flange 13, a second channel opening 15 located at the bottom of the heating base 1, and a connecting channel 16 located between the first channel opening 14 and the second channel opening 15.

[0050] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, both the first connecting portion and the second connecting portion are located on the heating base and on the side closer to the container. In some embodiments, when the container extends into the surface of the heating base, the protruding edge can support the container, and an insulating surface is formed between the container and the protruding edge, limiting the continuous loss of heat towards the first connecting portion. In some embodiments, the protruding edge can block the continuous loss of heat between the center of the second connecting portion and the heating base towards the first connecting portion.

[0051] Specifically, the first channel opening, the second channel opening, and the connecting channel form a heat dissipation channel, which can promptly dissipate heat between the container and the heating base, preventing excessive heat accumulation inside the heating base. This reduces the risk of performance degradation, aging, or even damage to components due to prolonged exposure to high temperatures, ensuring the stable operation and service life of the entire liquid heater. Hot air flows from the higher-temperature first channel opening along the connecting channel to the bottom second channel opening, accelerating the heat dissipation process through air convection, thereby improving heat dissipation efficiency.

[0052] In addition, the upwardly extending convex edge between the first connecting part and the second connecting part can enhance the stability of the first connecting part and the second connecting part, and also strengthen the thickness and strength of the heating seat structure. This makes the heating seat less prone to deformation and cracking when subjected to temperature changes, component weight and external impact, thereby ensuring the structural stability of the limiting chamber.

[0053] like Figures 2 to 5 The liquid heater shown has an automatic temperature control. The heating assembly 3 is provided with a heating plate 31 covering the area of ​​the second connection part 12. The bottom of the heating plate 31 is close to the upper side of the temperature detection end 51.

[0054] Optionally, in some embodiments, the heating plate is positioned in the area between the center of the second connecting part and the heating base. The convex edge is used to limit the heat loss of the heating plate towards the first connecting part. The bottom of the heating plate is close to the upper side of the temperature detection end, so that the sensor can perceive the temperature change of the heating plate more closely and directly. This provides more accurate temperature feedback to the electronic control components, enables more precise adjustment of the power of the heating components, and ensures that the liquid heating can reach the ideal set temperature and maintain stability.

[0055] Alternatively, in some embodiments, the heating plate contacts the container and directly heats the bottom of the container.

[0056] Optionally, in some embodiments, the heating plate can be heated by means of an electric ceramic stove, an induction cooker, a heating wire, etc.

[0057] like Figure 6The automatic temperature control liquid heater shown, the sensor 5 is equipped with the control piece 54 located in the limiting chamber 6 and electrically connected with the temperature detection end 51, the wiring end 55 electrically connected with the control piece 54 and the electric control component 4 respectively, and the water level detection end 52 electrically connected with the control piece 54, wherein the water level detection end 52 is a non-contact liquid level sensor.

[0058] Optionally, in some embodiments, the control piece is an MCU chip, the wiring end can be used for connecting a wire by reading and processing the data of the temperature detection end and the water level detection end.

[0059] Further, as the preferred embodiment of the utility model but not limited, the sensor integrates temperature detection, water level detection and control reading data functions, which can further simplify the system structure, reduce the number of required components, thereby reducing the overall cost and installation complexity. Because the connection points between components are reduced, the failure rate can also be reduced.

[0060] In addition, the non-contact liquid level sensor is used as the water level detection end, which avoids the performance decline or failure problem of the traditional contact sensor caused by liquid corrosion, high temperature environment, sediment accumulation or mechanical wear. The non-contact sensor can accurately measure the liquid level and is not affected by the conductivity and viscosity of the liquid, has lower maintenance cost and longer service life. The water level detection end can timely detect abnormal conditions such as water overflow and dry burning, thereby prolonging the service life of the liquid heater.

[0061] Specifically, in some embodiments, the container is made of glass material, and the water level detection end of the utility model is suitable for non-metal containers. The non-contact liquid level sensor detects the liquid by penetrating the outer wall of the non-metal container such as plastic, glass, ceramic, etc. and sensing the liquid, and the sensing distance can reach 20mm. It does not need to be in direct contact with the liquid, has high stability, high sensitivity, strong anti-interference ability, is not affected by external electromagnetic interference, has wide application range and strong sensing ability.

[0062] As shown in Figure 6 and Figure 9 The automatic temperature control liquid heater shown, the water level detection end 52 is arranged along the horizontal direction and located at the first limiting chamber opening 61, the sensor 5 is equipped with the detection opening 53 located at the water level detection end 52, the temperature detection end 51 is arranged in the detection opening 53, and the control piece 54 and the wiring end 55 are located on one side close to the second limiting chamber opening 63.

[0063] Further, as the preferred embodiment of the utility model but not limited, the water level detection end is arranged along the horizontal direction and located at the first limiting chamber opening, which can be closer to the container and can more directly and accurately detect the change of the liquid level.

[0064] Optionally, in some embodiments, the detection opening exposes the temperature-sensing element (such as a thermistor, thermocouple, or RTD) at the temperature sensing end directly to the environment, reducing the obstruction of heat conduction by the heating assembly's housing. Free airflow allows the sensor to contact the ambient temperature more evenly, reducing localized temperature deviations.

[0065] Additionally, the control components and wiring terminals are located on the side near the opening of the second limiting chamber, making sensor installation and maintenance more convenient. The control components are positioned away from the container or the heating element, better preventing them from being exposed to high temperatures for extended periods, thus extending their lifespan.

[0066] like Figures 2 to 9 The liquid heater with automatic temperature control shown includes a heating base 1 comprising a housing 7 and a base 8 connected to the housing 7. The housing 7 has a housing connecting end 71 and a housing channel 72 connected to the first channel opening 14. The base 8 has a base mating end 81 that mates with the housing connecting end 71 and a base channel 82 that communicates with the housing channel 72 and the second channel opening 15 respectively. The housing channel 72 and the base channel 82 together form the connecting channel 16.

[0067] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, the operator can first install the electronic control components, sensors, and other components inside the housing, and then enclose the housing channel and the base channel to form a connecting channel. The housing connecting end and the base mating end are then connected to ensure a stable connection between the housing and the base. The housing and the base support each other and work together to enhance the overall structural strength of the heating base. The layout of the heat dissipation channel inside the heating base is more stable and less prone to deformation or blockage due to external forces such as squeezing or collision. This ensures that hot air can flow smoothly from the opening of the first channel through the connecting channel to the opening of the second channel, maintaining a good heat dissipation effect and preventing heat accumulation inside the heating base due to damage to the heat dissipation channel, which would affect the normal operation and service life of the components.

[0068] The shell connection end and the base mating end can be connected by means of snap-fit ​​connection, fastener connection, magnetic connection, mortise and tenon connection, etc.

[0069] like Figures 2 to 9The liquid heater with automatic temperature control shown has a base 8 with a base receiving cavity 83. The base receiving cavity 83 has an air inlet 84, an exhaust port 85 located at the bottom of the base 8, a first base connecting end 86 located at the bottom of the base 8 and extending upward, and a heat dissipation device 87 connected to the first base connecting end 86. The exhaust port 85 and the heat dissipation device 87 are arranged opposite to each other. The housing 7 has an operating component 73 connected to the electronic control component 4.

[0070] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, during operation, cold air from the outside can enter the base cavity through the air inlet, carrying away the heat generated inside the heating seat, and then the hot air is discharged from the exhaust port. The heat dissipation device is arranged opposite to the exhaust port, which can further enhance the heat exchange effect.

[0071] Specifically, the housing is equipped with operating components that connect to the electronic control assembly, allowing users to conveniently perform various operations when using the liquid heater, such as adjusting the heating temperature, setting the heating time, and selecting different heating modes. The location of the operating components on the housing makes them easily visible and operable by the user, enhancing the user experience.

[0072] In addition, the base can better support the weight of the container, heating components and other parts above the heating seat, and share the external pressure. The connection between the base and the heat dissipation device also helps to optimize the force distribution inside the base. Of course, the base has multiple support feet 80 on the lower side, which can further improve the stability of the base, improve heat dissipation efficiency, and ensure the structural safety and reliability of the entire liquid heater.

[0073] Alternatively, the heat dissipation device may be a cooling fan or a cooling fan with fins.

[0074] Optionally, the first base connection end and the heat dissipation device can be connected by means of snap-fit ​​connection, fastener connection, magnetic connection, mortise and tenon connection, etc.

[0075] The operating components can be operated via buttons, knobs, or electronic touchscreens.

[0076] like Figures 2 to 5 The liquid heater with automatic temperature control shown has a base accommodating cavity 83 with a second base connecting end 88 extending from bottom to top and a fixing member 89 connected to the second base connecting end 88. The fixing member 89 is used to connect with the electronic control component 4 or the heating component 3 so that the electronic control component 4 or the heating component 3 can be arranged opposite to the heat dissipation device 87.

[0077] Furthermore, as a preferred embodiment of this utility model and not a limitation, a fixing member is connected via the second base connection end. This fixing member is used to connect to the electronic control component or heating component, allowing the electronic control component or heating component to be positioned opposite the heat dissipation device. This enables the heat generated by the electronic control component or heating component during operation to be transferred to the heat dissipation device in the shortest distance and most direct manner. The shortened heat transfer path means that heat can be absorbed and dissipated by the heat dissipation device more quickly, effectively preventing heat accumulation around these critical components. This ensures that the electronic control component and heating component are always in a suitable temperature environment, maintaining stable performance, reducing the risk of failure due to high temperatures, and improving the reliability and service life of the entire liquid heater.

[0078] Specifically, the second base connection end and fixing parts provide a stable connection method for the electrical control components or heating components, which can effectively prevent the electrical control components or heating components from becoming loose or displaced, and ensure that they maintain a relatively stable layout relationship with the heat dissipation device in their predetermined positions, thus ensuring the continuous and effective heat dissipation function. At the same time, it also enhances the integrity and stability of the entire internal structure of the liquid heater, enabling it to better withstand external forces and reduce problems such as poor wiring connections caused by component shaking.

[0079] Alternatively, the second base connection end and the fixing component can be connected by means of snap-fit ​​connection, fastener connection, magnetic connection, mortise and tenon connection, etc.

[0080] Example 1

[0081] like Figures 1 to 9 The liquid heater with automatic temperature control shown includes a heating base 1, a container 2 connected to the heating base 1, and a heating assembly 3 for heating the container 2. The heating base 1 is provided with an electronic control assembly 4 electrically connected to the heating assembly 3, a sensor 5 for detecting temperature and connected to the electronic control assembly 4, and a limiting chamber 6 for accommodating the sensor 5. The sensor 5 is provided with a temperature detection end 51. The limiting chamber 6 is provided with a first limiting chamber opening 61 for the temperature detection end 51 to extend out. The limiting chamber 6 is arranged in a horizontal direction and is provided with a support part 62 for supporting the sensor 5. The sensor 5 is close to the bottom of the container 2 or the heating assembly 3 so that the power of the heating assembly 3 can be adjusted by the electronic control assembly 4.

[0082] This utility model uses a horizontally positioned limiting chamber 6 to limit the sensor 5, and a support part 61 to stably support the sensor 5. This effectively avoids the problem of component deformation or failure caused by frequent up-and-down insertion and removal in traditional temperature measuring components. When the sensor 5 comes into contact with the bottom of the container 2 or the heating component 3, it will not be frequently displaced, and the temperature detection end 51 can maintain a fixed position, thereby ensuring the accuracy of temperature detection.

[0083] The sensor 5 is arranged in a horizontal direction, only the temperature detection end 51 is in the heating area, and other parts can be arranged in the limiting chamber 6 away from the heating area, so that the sensor can work stably for a long time.
