Description

Technical Field

[0001] This utility model relates to the field of health pot sensor technology, and in particular to a health pot sensor structure. Background Technology

[0002] With the improvement of people's living standards and the increasing emphasis on health and wellness, the health-preserving kettle, as a small household appliance that can conveniently perform health-preserving operations such as brewing tea, making soup, and stewing, has been widely used in the market. The functionality of the health-preserving kettle is inseparable from its internal sensor structure, which plays a key role in accurately controlling the working status of the kettle and ensuring its health-preserving effects.

[0003] Existing sensor structures for health-preserving kettles have several shortcomings in practical use. Firstly, some sensor structures have low testing accuracy, making it difficult to accurately detect parameters such as temperature inside the kettle. This results in inaccurate control of heat and time during tea brewing and soup simmering, affecting the health benefits and the taste of beverages and food. Secondly, some sensor structures have poor thermal conductivity, leading to slow heat transfer and delayed temperature response. Furthermore, their pressure resistance is limited, and their waterproofing is inadequate, making them susceptible to water intrusion and damage, reducing the sensor's lifespan and reliability. In addition, the thermistors used in traditional sensor structures suffer from long response times and poor consistency, which not only affects the efficiency of the health-preserving kettle but may also lead to performance instability between different batches of products.

[0004] Therefore, it is necessary to design a sensor structure for the health pot to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a sensor structure for health-preserving kettles. This sensor structure has advantages such as high testing accuracy, fast heat conduction in encapsulation, high pressure resistance and waterproof function, fast response time of the thermistor, high consistency, long service life and stable reliability, providing a strong guarantee for improving the performance of health-preserving kettles.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A sensor structure for a health-preserving kettle includes a housing. A terminal block is located at the upper end of the housing. A first wire is connected to the right side of the terminal block, and a grounding terminal is connected to the right side of the first wire. A thermistor is located inside the housing. The right sides of the two pins of the thermistor extend to the outside and are fixedly connected to a second wire. A latch is connected to the right side of both second wires. A rubber shell is located on the right side of the latch, and a connecting terminal is fixedly connected to the right side of the latch. An insertion groove is located on the left inner wall of the rubber shell, and the connecting terminal extends into the insertion groove.

[0008] Preferably, two first heat-shrink tubings are fixedly connected to the right side of the housing, and the connection points of the two pins of the two thermistors and the second wire are located inside the corresponding first heat-shrink tubings. A second heat-shrink tubing is provided on the right side of the housing, and the two first heat-shrink tubings are located inside the second heat-shrink tubing.

[0009] Preferably, the first heat shrink tubing is white and the second heat shrink tubing is black.

[0010] Preferably, an identification tube is fitted onto the first wire, and the identification tube has a white grounding symbol.

[0011] Preferably, the terminal block is a 4mm copper sheet, and the housing is made of SUS304 stainless steel.

[0012] Preferably, the length of the first wire is 140±10mm.

[0013] Compared with existing technologies, the advantages of this device are:

[0014] 1. Compared with existing technologies, the thermistor used in the sensor structure of this health pot has precise parameter settings. This high-precision parameter setting enables the sensor to more accurately sense temperature changes, thereby achieving accurate detection of the temperature inside the health pot. This avoids the problem of inaccurate heat and time control during tea brewing and soup making due to insufficient testing accuracy, greatly improving the health benefits and the taste of beverages and food.

[0015] 2. Compared with existing technologies, the outer shell of this device is made of SUS304 stainless steel, combined with a carefully designed heat-shrink tubing encapsulation structure. This encapsulation method not only has a fast heat conduction speed, enabling rapid heat transfer and achieving a fast temperature response, but also has high pressure resistance, effectively resisting external pressure. At the same time, the excellent waterproof design prevents water from entering the sensor, avoiding damage due to moisture and affecting its service life, greatly improving the stability and reliability of the sensor structure;

[0016] 3. Compared with existing technologies, the thermistor in the sensor structure of this health pot has a faster response time and higher consistency. The fast response time allows the health pot to adjust its working state in a timely manner according to temperature changes, improving work efficiency. The good consistency ensures stable performance between different batches of products, providing users with a more stable and reliable experience, effectively solving the problems of slow response and unstable performance of traditional thermistors.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1 A sensor structure for a health-preserving kettle includes a housing 1. A terminal block 2 is located at the upper end of the housing 1. The terminal block 2 is a 4mm copper strip, which has good conductivity, ensuring stable current transmission and meeting the electrical connection requirements of the health-preserving kettle during operation. The housing 1 is made of SUS304 stainless steel, which is corrosion-resistant and has high strength, effectively protecting internal components such as the thermistor 3, extending the sensor's lifespan. Its smooth surface makes it easy to clean, meeting the environmental requirements of the health-preserving kettle. A first wire 5 is connected to the right side of the terminal block 2. The length of the first wire 5 is 140±10mm. This length design ensures that the first wire 5 meets connection requirements without being too long to cause tangling or too short to affect installation. A grounding terminal 8 is connected to the right side of the first wire 5. The grounding terminal 8 effectively conducts static electricity or abnormal current generated by the sensor to the ground, preventing damage to the sensor and other components of the health-preserving kettle, ensuring electrical safety. The housing 1 houses a thermistor 3. The two pins of the thermistor 3 extend to the outside and are fixedly connected to a second wire 6. The connection between the second wire 6 and the thermistor 3 pins employs a reliable connection process, ensuring stable signal transmission from the thermistor 3 to subsequent circuits and avoiding signal instability caused by loose connections. A latch 10 is connected to the right side of both second wires 6. A housing 11 is located on the right side of the latch 10, and a connecting terminal 9 is fixedly connected thereto. An insertion slot is located on the left inner wall of the housing 11, and the connecting terminal 9 extends into this slot. The connecting terminal 9 serves to collect and transfer the electrical signals from the second wires 6. Its reasonable structural design ensures reliable connection with the second wires 6 and subsequent components, enabling smooth signal transmission. The housing 11 protects the connecting terminal 9 from external physical damage, dust, and moisture, improving its stability and lifespan. The thermistor 3 has a nominal resistance value at 25 degrees Celsius. The material constant of thermistor 3 ,in The material constant of the thermistor 3 is given when the temperature changes from 25 degrees Celsius to 50 degrees Celsius.

[0021] Two first heat-shrink tubing 4 are fixedly connected to the right side of the outer casing 1. After being heated and shrunk, the first heat-shrink tubing 4 can tightly wrap the connection between the pins of the thermistor 3 and the second wire 6, providing insulation, moisture protection, and fixation. This further improves the reliability of the connection and prevents short circuits or poor contact caused by external factors. The connection between the two pins of the two thermistors 3 and the second wire 6 is located inside the corresponding first heat-shrink tubing 4. A second heat-shrink tubing 12 is provided on the right side of the outer casing 1. The second heat-shrink tubing 12 provides secondary protection for the two first heat-shrink tubing 4, enhancing the protective performance of the entire sensor structure and better resisting external mechanical impacts and environmental corrosion. The two first heat-shrink tubing 4 are located inside the second heat-shrink tubing 12. The first heat-shrink tubing 4 is white, and the second heat-shrink tubing 12 is black. The white first heat-shrink tubing 4 has good moisture-proof and insulation properties, while the black second heat-shrink tubing 12 has high temperature resistance and anti-aging properties.

[0022] The first wire 5 is fitted with an identification tube 7, which has a white grounding symbol. The white grounding symbol on the identification tube 7 can clearly indicate the grounding attribute of the first wire 5, making it convenient for installers to quickly identify and confirm during installation and maintenance. This avoids safety hazards and equipment failures caused by wiring errors, and improves the efficiency and accuracy of installation and maintenance.

[0023] The functional principle of this invention can be explained through the following operation: The sensor is installed on the liquid level plate inside the health pot. When the liquid level inside the pot changes, the sensor on the liquid level plate can detect the rise and fall of the liquid level in real time. The sensor converts the liquid level change information into an electrical signal and can accurately output the electrical signal corresponding to the liquid level information.

[0024] The output electrical signal is transmitted to the control circuit via the second wire 6 connected to the sensor. The control circuit analyzes and processes the received electrical signal, and determines whether the liquid level is within the normal range according to the preset program and algorithm. When the liquid level is lower than the preset minimum liquid level, the control circuit will issue a corresponding instruction, which can remind the user to add liquid through the display module, or control the kettle to stop working to prevent dry burning.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
