Description

Technical Field

[0001] The present application relates to the technical field of health-preserving kettles, and in particular to a heating base and a health-preserving kettle. Background Art

[0002] A health kettle is a small household appliance designed for healthy living. It typically has multiple functions, such as brewing tea, stewing soup, cooking porridge, and keeping food warm. Made of heat-resistant glass or stainless steel, these kettles offer excellent insulation and corrosion resistance. Their compact size makes them easy to store, making them suitable for modern homes and offices.

[0003] However, most of the heating bases of existing health kettles use KSD temperature controllers to start and stop the heating disc, and are unable to collect the heating temperature of the heating disc in real time to adjust the heating power of the heating disc, thereby failing to keep the heating disc in the optimal heating state. Therefore, technicians in this field urgently need to develop a new type of health kettle to meet actual application needs. Utility Model Content

[0004] The main purpose of this application is to provide a heating base to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, the present application proposes a heating base, comprising a housing and a PCB circuit board disposed on the housing, a heating plate disposed within the housing and connected to the PCB circuit board, and a heat shield disposed under the heating plate to separate the heating plate from the heating plate, wherein a connecting post is provided on the underside of the heating plate, penetrating downwardly through the heat shield and extending from the underside of the heat shield;

[0006] The heating base further includes a temperature sensor disposed on the lower side of the heat insulation cover, one end of the temperature sensor is connected to the connecting column, and the other end is connected to the PCB circuit board.

[0007] As described above, the heating base has a first heat-insulating cavity formed between the heat-insulating cover and the heating plate.

[0008] As described above, the heating base further includes a reflective cover arranged outside the heat insulation cover and connected to the heat insulation cover.

[0009] As described above for the heating base, the reflective cover and the heat insulating cover form a second heat insulating cavity.

[0013] In the heating base as described above, the temperature sensor is an NTC temperature sensor.

[0014] The present application also provides a health-preserving kettle, comprising the heating base as described above, and a kettle body that can be placed on the heating base.

[0015] As described above, the health-preserving kettle, the heating base further comprises a temperature acquisition sensor provided on the shell and located on the upper side of the heating plate and connected to the PCB circuit board for acquiring the temperature of the kettle body.

[0016] Compared with the prior art, the above application has the following advantages:

[0017] 1. The present application uses the temperature sensor provided on the lower side of the heat insulation cover to collect and obtain the actual working temperature of the heating disk in real time, convert it into a real-time temperature signal and transmit it to the PCB circuit board, and then adjust the heating power of the heating disk in real time through the control circuit on the PCB circuit board, so that the heating disk is in the optimal heating state in real time, and at the same time it is beneficial to ensure that the temperature of the heating disk and the environment in which the heating disk is located is within the set temperature range, thereby preventing the heating disk and the attached connecting parts from overheating and other faults; in addition, the design of the heat insulation cover can effectively isolate the heat generated by the heating disk, preventing the heat from being directly transferred to the outside of the shell, thereby protecting the safety of the user and reducing the impact of heat on the surrounding environment.

[0018] 2.

Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0027] In one embodiment of the present application, Figures 1 to 4 As shown, a heating base includes a housing 1 and a PCB circuit board 2 arranged on the housing 1, a heating plate 3 arranged in the housing 1 and connected to the PCB circuit board 2, and a heat shield 4 provided on the lower side of the heating plate 3 to separate the heating plate 3. The lower side of the heating plate 3 is provided with a connecting column 31 that downwardly penetrates the heat shield 4 and extends to the lower side of the heat shield 4;

[0028] The heating base further includes a temperature sensor 5 provided on the lower side of the heat shield 4 . One end of the temperature sensor 5 is connected to the connecting post 31 , and the other end is connected to the PCB 2 .

[0029] The heating base of the present application uses the temperature sensor 5 provided on the lower side of the heat insulation cover 4 to enable real-time collection and acquisition of the actual working temperature of the heating disk 3, which is then converted into a real-time temperature signal and transmitted to the PCB circuit board 2, and then the heating power of the heating disk 3 is adjusted in real time through the control circuit on the PCB circuit board, so that the heating disk 3 is in the optimal heating state in real time, and at the same time is conducive to ensuring that the temperature of the heating disk and the environment in which the heating disk is located is within the set temperature range, thereby preventing the heating disk and the attached connecting parts from overheating and other faults; in addition, the design of the heat insulation cover 4 can effectively isolate the heat generated by the heating disk 3, preventing the heat from being directly transferred to the outside of the shell 1, thereby protecting the safety of the user and reducing the impact of heat on the surrounding environment.

[0030] Furthermore, a first heat-insulating cavity 100 is formed between the heat-insulating cover 4 and the heating plate 3 , which has the advantage of delaying the downward conduction of heat from the heating plate 3 .

[0031] Furthermore, the heating base also includes a reflective cover 6 arranged on the outside of the heat insulation cover 4 and connected to the heat insulation cover 4. The advantage of this is that it can further delay the downward conduction of heat from the heating plate 3, and at the same time it is beneficial to reflect and conduct heat to the heating plate 3, thereby increasing the heating rate of the heating plate 3 and reducing power consumption, thereby achieving energy saving and emission reduction effects.

[0032] Furthermore, the reflector cover 6 and the heat insulation cover 4 form a second heat insulation cavity 200. This has the advantage of forming a secondary delay in the downward conduction of heat from the heating plate 3.

[0033] Furthermore, the heating base also includes a fastening mounting bracket 7 provided on the lower side of the reflector 6 for fastening the reflector 6 , the purpose of which is to achieve a fastening connection effect.

[0034] Furthermore, a third heat-insulating cavity 300 is formed between the fastening mounting frame 7 and the reflector 6. The advantage of this cavity is that it can delay the downward conduction of heat from the heating plate 3 three times.

[0035] Furthermore, the heating base also includes a mounting bracket 8 arranged inside the fixing mounting frame 7, and a temperature fuse 9 arranged on the mounting bracket 8 and connected to the PCB circuit board 2. The advantage is that when an abnormally high temperature is detected, the power supply can be immediately cut off or the working state of the heating plate 3 can be adjusted, thereby avoiding safety hazards caused by overheating.

[0036] Furthermore, the temperature sensor 5 is an NTC temperature sensor, which has the advantages of high sensitivity, fast response speed, good insulation and sealing, resistance to mechanical collision, and resistance to bending.

[0037] The present application also provides a health pot, comprising the above-described heating base and a pot body 2000 that can be placed on the heating base. The heating base also includes a temperature acquisition sensor 10 disposed on the housing 1, located above the heating disk 3, and connected to the PCB circuit board 2 for acquiring the temperature of the pot body 2000. The temperature acquisition sensor 10 is preferably an infrared temperature sensor. The heating base of the present application uses the temperature sensor 5 disposed on the underside of the heat shield 4 to enable real-time acquisition of the actual operating temperature of the heating disk 3. The temperature signal is then converted into a real-time temperature signal and transmitted to the PCB circuit board 2. The control circuit on the PCB circuit board then adjusts the heating power of the heating disk 3 in real time, thereby ensuring that the heating disk 3 is in an optimal heating state in real time. This helps ensure that the temperature of the heating disk and the surrounding environment of the heating disk are within a set temperature range, thereby preventing the heating disk and its associated connecting parts from overheating. In addition, the design of the heat shield 4 effectively isolates the heat generated by the heating disk 3, preventing the heat from being directly transferred to the outside of the housing 1, thereby protecting the safety of the user and reducing the impact of heat on the surrounding environment.
