Description

Technical Field

[0001] The present invention relates to the field of precise temperature control systems and equipment for liquid heating components, and in particular to a precise temperature control system for a titanium crystal heater and related equipment. Background Art

[0002] Titanium and its alloys have many excellent properties, such as low density, high melting point, high specific strength, corrosion resistance, good high and low temperature performance, non-magnetic properties, low damping of sound waves and vibrations, good biocompatibility, good compatibility with carbon composites, superconductivity, shape memory and hydrogen absorption properties. Therefore, titanium is called "space metal" and "ocean metal" and is increasingly being used in the production of human health.

[0003] Titanium crystal is an inclusion crystal. Its exterior is translucent, yet its interior contains numerous irregularly interlaced, plate-like and banded rutile minerals. These golden and golden-brown minerals radiate a dazzling brilliance under sunlight, making titanium crystal highly valued in the market. Coupled with its potent properties, titanium crystal is also known as the "best of crystals."

[0004] Titanium crystal technology is currently widely used in everyday food and beverage utensils, particularly electrical appliances. Due to the highly dynamic physical properties of titanium crystals, the color and surface finish of titanium crystals vary greatly. However, the temperature control of existing titanium crystal heaters is not precise enough, necessitating improvements. Summary of the Invention

The thermal connection further enhances the efficiency of heat conduction between the titanium-based crystal treated outer layer, the energy storage and heat storage layer, and the heating element. The temperature sensing element detects temperature. The electrical control assembly receives information from the temperature sensing element and controls the heating of the heating element. The two temperature sensing elements are independently connected to the electrical control assembly, allowing them to operate independently, thereby improving the accuracy and stability of the temperature control system. The temperature sensing surfaces of the titanium-based crystal heating element are independently positioned in different temperature distribution zones, allowing the temperature sensing elements to detect different locations and temperatures, providing more comprehensive and complete temperature information, further improving the accuracy and stability of the temperature control system.

[0009] Through the above design, the present invention improves the heat conduction efficiency of the titanium-based crystalline heating component and realizes independent detection of temperature zones by dual temperature sensing elements, thereby achieving precise temperature control with high stability.

[0019] The setting of the titanium-based crystallization-treated outer temperature-sensing plane improves the temperature detection accuracy and stability of the titanium-based crystallization-treated outer temperature-sensing plane.

[0020] Preferably, in the above-mentioned precise temperature control system of the titanium crystal material heater, the energy storage and heat storage layer is spaced around the temperature-sensing plane of the titanium-based crystal-treated outer layer.

[0021] The above design takes into account both the strength of the connection structure and the independence of the temperature-sensing surface of the titanium-based crystallized outer layer.

[0023] The above design improves the temperature detection accuracy and stability of the edge joint.

[0024] Preferably, in the above-mentioned precise temperature control system of a titanium crystal material heater, the temperature sensing plane of the titanium-based crystal heating component is extended from the energy storage and heat storage layer to form an energy storage and heat storage layer temperature sensing plane, the titanium-based crystal treated outer layer is provided with a titanium-based crystal treated outer layer temperature sensing plane, the temperature sensing plane of the titanium-based crystal heating component is also provided on the titanium-based crystal treated outer layer temperature sensing plane of the titanium-based crystal treated outer layer, and the two temperature sensing elements are respectively provided in the energy storage and heat storage layer temperature sensing plane and the titanium-based crystal treated outer layer temperature sensing plane.

[0025] The two temperature sensing elements are respectively arranged in the temperature sensing plane of the energy storage and heat storage layer and the temperature sensing plane of the titanium-based crystallization treated outer layer, so that the detection positions and temperatures of the temperature sensing elements are different, making the temperature information more comprehensive and complete, and adapting to more scenarios, thereby further improving the accuracy and stability of the temperature control system.

[0030] Preferably, in the above-mentioned precise temperature control system for a titanium crystal material heater, the two electrical control elements are electrically connected in series.

[0031] The above design ensures the operational stability of the electrical control components.

[0032] Preferably, in the above-mentioned precise temperature control system of the titanium crystal material heater, the two temperature sensing elements are provided with different triggering temperatures, and the two temperature sensing elements are provided with a triggering sequence.

[0033] This design ensures the accuracy and stability of the temperature control system. Temperature sensors are set to different trigger temperatures in different temperature zones. Triggering any of these sensors will control the temperature. For example, when a titanium-based crystalline heating element heats a titanium cup filled with water, the temperature of the titanium-based crystalline outer layer rises faster than the energy storage layer. However, if the titanium cup is dry-burning due to lack of water, the energy storage layer will rise faster than the temperature of the titanium-based crystalline outer layer.

[0034] Preferably, in the above-mentioned precise temperature control system of the titanium crystal material heater, the triggering action of the temperature sensing element has a corresponding relationship with the operating temperature of the titanium-based crystal heating component.

[0035] This design ensures stable operation of the titanium-based crystal heating component. The temperature sensing element detects the temperature of the titanium-based crystal treated outer layer, with a trigger temperature range of 45°C to 100°C. Before the temperature sensing element detects the temperature reaches the user-set value, it shuts off the power and stops heating, allowing residual heat to raise the temperature to the user-set value.

[0037] This design ensures the stable operation of the titanium-based crystalline heating element. The trigger temperature of the temperature sensing element that detects the energy storage layer is no higher than 130°C. After the power is turned off and heating stops, the residual heat energy causes the titanium-based crystalline heating element to rise to 220°C to 250°C.

[0038] Preferably, in the above-mentioned precise temperature control system of the titanium crystalline material heater, the triggering action of the two temperature sensing elements has a corresponding relationship with the thermal deformation temperature of the titanium-based crystalline heating component.

[0045] The setting of thyristors ensures the stability of electrical control components, takes into account the operating effect and cost of electrical control components, and makes the triggering action of electrical control components more efficient through chip control.

[0046] Preferably, in the above-mentioned precise temperature control system for a titanium crystal material heater, no less than three independent temperature sensing elements are provided in the temperature controller.

[0047] No less than three independent temperature sensing elements improve the accuracy, stability and safety of the temperature control system.

[0050] Compared with the prior art, the present invention has the following beneficial effects:

[0051] 1. This invention accelerates heat transfer and abnormality detection by providing an energy storage layer on the titanium-based crystal treated outer layer, allowing the centralized heating of the heating element to have a buffering and heat storage process, thus enabling the titanium-based crystal heating component to have the heat conduction efficiency and high-precision temperature control function of aluminum components.

[0052] 2. The connection method of the titanium-based crystallized outer layer and the energy storage and heat storage layer in the present invention is brazing, which specifically solves the defect that titanium materials are not easy to weld with other metal materials, making the structural connection and heat conduction method of the titanium-based crystallized heating component more reliable;

[0053] 3.

This allows the temperature controller to more accurately detect and control the temperature of the heating element. Based on the detection results of the two independent temperature sensing elements, the temperature controller can determine the temperature status in different scenarios. This not only verifies the heating function, but also detects welding safety and abnormal heating conditions of related equipment, making the temperature control system more widely applicable and reliable.

[0059] Figure 6 The structure of the titanium-based crystal heating component in the present invention is shown as follows: Figure 2 . DETAILED DESCRIPTION

[0060] The following is combined with Figure 1-6 The present invention is further described in detail with specific embodiments, but they are not intended to limit the present invention:

[0061] like Figure 1 As shown, the titanium-based crystalline heating component 1 is fixedly connected to the temperature controller 2, and a closed-loop control circuit is formed through electrical connection. The titanium-based crystallized outer layer 11 is brazed to the energy storage and heat storage layer 12, and the heating element 13 is thermally conductively connected to the energy storage and heat storage layer 12. The temperature sensing element 211 and the temperature sensing element 212 are independently driven and connected to the electrical control component 22 respectively. The temperature sensing element 211 contacts the energy storage and heat storage layer 12 to detect the temperature of the energy storage and heat storage layer 12. The temperature sensing element 212 contacts the titanium-based crystallized outer layer 11 to detect the temperature of the titanium-based crystallized outer layer 11.

[0062] like Figure 2 As shown, the titanium-based crystallized outer layer 11 is brazed to the energy storage and heat storage layer 12, and the heating element 13 is thermally conductively connected to the energy storage and heat storage layer 12. The heating element 13 is a tubular resistive heating element, and the energy storage and heat storage layer 12 is made of aluminum. The energy storage and heat storage layer 12 extends to form an energy storage and heat storage layer temperature sensing plane 141, and the titanium-based crystallized outer layer 11 forms a titanium-based crystallized outer layer temperature sensing plane 142. The energy storage and heat storage layer 12 surrounds the titanium-based crystallized outer layer temperature sensing plane 142 at intervals. The titanium-based crystallized outer layer 11 and the energy storage and heat storage layer 12 form an edge joint 143, thereby independently setting the temperature sensing plane 14 of the titanium-based crystallized heating component in different temperature distribution zones.

[0063] like Figure 3 As shown, the temperature controller 2 is provided with a temperature sensing element 211, a temperature sensing element 212, and an electrical control component 22. The temperature sensing element 211 and the temperature sensing element 212 are independently driven and connected to the electrical control component 22, independently sensing different temperature distribution areas and triggering the electrical control component 22. The temperature sensing element 211 and the temperature sensing element 212 are provided with a triggering sequence, and their triggering actions correspond to the safe use temperature, thermal deformation temperature and thermal deformation temperature of the titanium-based crystalline heating component 1. The triggering action of the temperature sensing element 212 corresponds to the working temperature of the titanium-based crystalline heating component 1. The temperature controller 2 is also provided with a temperature sensing element 213 with a FUSE function.

[0064] like Figure 4 As shown, the temperature controller 2 is equipped with an electrical control assembly 22, which includes electrical control elements 221 and 222. Electrical control elements 221 and 222 are electrically connected in series. Temperature sensing elements 211 and 212 trigger electrical control elements 221 and 222, respectively. Electrical control element 221 is a relay, and electrical control element 222 is a thyristor.

[0065] like Figure 5 As shown, the temperature-sensing plane 14 of the titanium-based crystalline heating component extends from the energy storage and heat storage layer 12 to form an energy storage and heat storage layer temperature-sensing plane 141. The temperature-sensing plane 14 of the titanium-based crystalline heating component is also arranged on the titanium-based crystallized outer layer temperature-sensing plane 142 of the titanium-based crystallized outer layer 11. The temperature sensing element 211 and the temperature sensing element 212 are respectively arranged in the energy storage and heat storage layer temperature-sensing plane 141 and the titanium-based crystallized outer layer temperature-sensing plane 142. The temperature sensing element 211 and the temperature sensing element 212 independently sense the heat of the temperature-sensing plane 14 of the titanium-based crystalline heating component and trigger the electrical control component 22. The electrical control component 22 is provided with an electrical control element 221, and the temperature sensing element 211 triggers the electrical control element 221. The electrical control element 221 is a relay.

[0066] like Figure 6As shown, the density distribution of the annular corrugated lines describes the heat distribution of the heating element 13 in the titanium-based crystalline heating component 1. Since heat conduction takes time and will be dissipated to a certain extent, the closer to the heating element 13, the relatively denser the heat distribution lines are, and the temperature at the same time point is relatively high, and the correspondence with the working state of the heating element 13 is more sensitive. When setting the temperature-sensing plane 14 of the titanium-based crystalline heating component, it is not the case that the closer to the heating element 13 the better, because if it is too close, the temperature will be too sensitive, and the electrical control component 22 will be frequently triggered, which is also a loss for the operating life of the electrical control element 221 and the electrical control element 222. However, the farther the temperature-sensing plane 14 of the titanium-based crystalline heating component is from the heating element 13, the lower the temperature sensitivity will be. Different usage scenarios have different control over the temperature. In the present invention, the temperature sensing element 211 and the temperature sensing element 212 are set on different temperature sensing planes to detect temperature data of different temperature distribution areas. The trigger temperatures of the temperature sensing elements 211 and 212 are set to different temperature values, so that the detection and triggering of different temperature values ​​can be completed through the order and frequency of the triggering actions in different usage scenarios, thereby achieving precise temperature control of the heating element 13. When the titanium-based crystallized outer layer 11 serves as the working surface in contact with food or water, the temperature-sensing plane 142 of the titanium-based crystallized outer layer is a cold zone. Since its temperature is relatively far away from the heating element 13, the operation of the heating element 13 has a limited impact on its temperature change, making the temperature of food or water relatively easy to detect. The cold zone adds detection of the temperature limit of the titanium-based crystallized outer layer 11 when detecting the temperature of food or water. The trigger temperature of the temperature sensing element 212 is set to the required pre-value relative to the color change temperature limit of the titanium-based crystallized outer layer 11. When it is detected that the temperature of the food or water reaches the pre-value, it is triggered to achieve precise temperature control of the heating element 13. At the same time, the energy storage and heat storage layer temperature sensing plane 141 is a hot zone. The temperature sensing element 211 located in the hot zone simultaneously detects temperature changes in the hot zone. The hot zone is close to the heating element 13 and is relatively sensitive to temperature changes of the heating element 13. It is configured to detect temperature changes of the heating element 13. Based on actual test data, a correspondence between the hot zone temperature and the temperature of the titanium-based crystallized outer layer 11 is set, and this correspondence is converted into a trigger temperature value for the temperature sensing element 211 located in the hot zone. Similar to the cold zone, the trigger temperature of the temperature sensing element 211 is set with a required pre-value relative to the color change temperature limit of the titanium-based crystallized outer layer 11 to ensure detection of the heating element 13, so that the overall triggering and control action does not cause the temperature value of the titanium-based crystallized outer layer 11 to reach the color change temperature limit. In addition, the present invention is provided with two relatively independent temperature sensing elements 211 and 212, which can be set in different action sequences according to actual scenarios, thereby realizing the application of the temperature control system in various scenarios.

The trigger values ​​for temperature sensing elements 211 and 212 are set to different temperatures based on actual test data. Even if one sensing element fails to detect, the other sensing element can still work independently, thus ensuring the reliability of temperature detection.

[0093] This embodiment can also set the temperature sensing element 211 as a thermosensitive bimetallic sensing element, and its trigger temperature is set to the pre-value required by the color change temperature limit of the titanium-based crystallized outer layer 11, and set the temperature sensing element 213 as a sensing element with a FUSE function, and its trigger value is much higher than the trigger value of the temperature sensing element 211. When in use, the temperature sensing element 211 first senses the temperature change of the heating element 13, and controls the switch action frequently and multiple times according to the actual set trigger temperature. The temperature sensing element 211 is a precise and frequently used functional component. When the temperature sensing element 211 causes temperature detection abnormalities due to temperature offset and service life, or even fails, the temperature sensing element 213 triggers the device to enter a permanent power supply path disconnection state, thereby ensuring the safety of the temperature control system application.

[0094] In short, the above description is only a preferred embodiment of the present invention, and all equivalent changes and modifications made within the scope of the patent application of the present invention should fall within the scope of the present invention.
