Description of the Invention: [Technical Field] The present invention relates to a cup cover structure having a thermoelectric element, and more particularly to an endothermic power generation by a thermoelectric element for using electric energy for detecting the temperature inside the display cup or subsequent Cup lid construction for cooling/heating. [Prior Art] In recent years, many electronic products have become sophisticated, streamlined, and miniaturized. Therefore, how to maintain the stability of products has become an important technical issue, in which the electrical energy generated by electronic products and the large amount of heat generated during operation, It becomes a major factor affecting stability. If the internal components of the product are overheated, it will cause permanent damage to the product. To overcome this problem, many electronic products have used thermoelectric cooling chips with heat sinks and cooling fans to help critical components such as CPUs dissipate quickly. The so-called thermoelectrically cooled wafer is formed by arranging particles of a plurality of n-type and p-type semiconductor materials and connecting the n-type and Ρ-type semiconductor materials with a plurality of metal conductors, and in the thermoelectrically cooled wafer. The two sides have an insulating ceramic sheet, wherein after a direct current is applied to the metal electrodes at both ends of the thermoelectrically cooled wafer, the electrons pass through the germanium-type semiconductor, thereby absorbing heat, and when the n-type semiconductor is discharged, the heat is released. An η/ρ module 'has heat from one side to the other, causing a temperature difference, forming a cold side and a heating side. This is called the Peltier effect. On the other hand, if the two sides of the thermoelectrically cooled wafer are stored in 201144170::degree f', a reverse temperature difference can be generated between the n and p semiconductors. This is the so-called Seebeck effect.
時至7日’熱電致冷晶片除了應用在電腦或家電等 電子產品之外’亦有許多業麵其顧於各式生活用品 中。例如，中華民國公告第漏92號新型專利揭示一 種保咖杯，其中保溫杯本體内具有—發溫元件、一散熱 片及-散熱風扇，發溫元件為致冷晶片，其接收一外部 電源’進而對保溫杯内之液體騎致冷或致熱^再者， 中華民國公告第MM3578麟型專㈣種冷熱雙 用變溫杯座結構，其係在一杯座内設置致冷熱晶片，其 接收一外部電源，以加熱或冷卻放置在杯座上的杯體。 另外，中華民國公告第M363268號新型專利揭示一種 可自行供電並顯示溫度之液體容器，其係在一容器本體 (即杯體）内底部設置一電路板、一溫度感應器、一溫度 顯示器、一溫差發電組件及一蓄電元件，在容器本體盛 有熱水時’該溫差發電組件能將熱能轉換成電能，以儲 存於蓄電元件，並用於該溫度感應器及溫度顯示器，以 顯示杯内溫度。 然而’上述熱電致冷晶片相關用品設計在實際使用 上仍具有下述問題，例如：第580892號之發溫元件内 建於保溫杯本體内，且需外接電源，使得發溫元件僅能 用於同一杯體，無法轉用到其他杯體，同時因杯體需設 置電源線或電源孔，使得杯體清洗時容易造成杯體内部 的電子元件受潮損壞，而影響使用壽命。第M283578 201144170 號之致冷熱晶片設於杯座雖可適用於各種杯體，但仍需 外接電源’且杯座體積較大，容易佔用空間，而造成使 用上的不便性。第M363268號之溫差發電組件雖可用 於發電及供電顯示溫度，但因其内建於容器本體(杯體） 内底部，故仍存在無法轉用到其他杯體，以及杯體清洗 時容易造成杯體内部的電子元件受潮損壞等問題，因而 影響使用壽命。同時，該溫差發電組件並未用於提供致 冷/致熱功能。再者，由於熱能通常通過蒸氣往上傳遞 及逸散，因此若將該溫差發電組件設於杯體内底部，則 無法在杯體内底部有效接收大部分的熱能，故會影響發 電效率’同時在杯底量測到的溫度亦非液體最高溫度 值。此外，若將熱電元件及溫度顯示器等設於杯體中， 則僅能用於同一杯體’無法設計成通用型式應用於不同 杯體或既有杯體，故會限制使用裕度。 故’有必要提供一種具有熱電元件的杯蓋構造，以 解決習知技術所存在的問題。 【發明内容】 本發明之主要目的在於提供一種具有熱電元件的杯 蓋構造，其中杯蓋係藉由熱電元件來吸收杯内熱能進行 發電，並將電能用於偵測顯示杯内溫度或後續用於致冷 /致熱工作，因而有利於提升杯蓋類產品之功能性及杯 類產品之使用便利性。 本發明之次要目的在於提供一種具有熱電元件的杯 201144170 蓋構造，其中熱電元件係設置於杯蓋内部，由於杯蓋與 杯體分開設置’因此對杯體進行清洗不致造成杯蓋内部 元件受潮，因而有利於提高杯蓋類產品之使用壽命。 本發明之另一目的在於提供一種具有熱電元件的杯 蓋構造，其中杯蓋另可設計成通用型式，以適用於各種 杯體之不同開口尺寸’因此有利於擴大杯蓋類產品之應 用範圍。 為達上述之目的，本發明提供一種具有熱電元件的 杯蓋構造，其包含··一杯蓋，具有一内部空間；以及， 一熱電模組，設於該杯蓋之内部空間内，且設有：一控 制電路；一充電電池，電性連接該控制電路；一熱電元 件，設於該杯蓋之底部，且電性連接該控制電路，其中 該控制電路用以切換該熱電元件與充電電池之間的From the 7th to the 'hot-heat-cooled wafers, in addition to electronic products such as computers and home appliances, there are many industries that take care of all kinds of daily necessities. For example, the Republic of China Announcement No. 92 new patent discloses a cup of coffee cup, wherein the body of the heat preservation cup has a temperature generating element, a heat sink and a cooling fan, and the temperature generating element is a cooling chip, which receives an external power source. In turn, the liquid in the thermos cup is cooled or heated. In addition, the Republic of China Announces the MM3578 Lin type special (four) type of hot and cold dual-purpose temperature-changing cup holder structure, which is provided with a hot and cold wafer in a cup, which receives an external A power source to heat or cool the cup placed on the cup holder. In addition, the Republic of China Announcement No. M363268 discloses a liquid container capable of self-powering and displaying temperature, which is provided with a circuit board, a temperature sensor, a temperature display, and a bottom in a container body (ie, a cup body). The thermoelectric power generation component and a power storage component, when the container body is filled with hot water, the thermoelectric power generation component converts thermal energy into electrical energy for storage in the electrical storage component, and is used for the temperature sensor and the temperature display to display the temperature inside the cup. However, the design of the above-mentioned thermoelectrically cooled wafer related articles still has the following problems in practical use. For example, the temperature generating component of No. 580892 is built in the body of the thermal insulation cup, and requires an external power supply, so that the heating element can only be used for The same cup can not be transferred to other cups. At the same time, the cup body needs to be equipped with a power cord or a power hole, so that the cleaning of the cup body easily causes the electronic components inside the cup to be damaged by moisture, which affects the service life. The cold heat chip of No. M283578 201144170 is suitable for various cups, but it still needs an external power supply. The cup holder is large in size and easy to occupy space, which causes inconvenience in use. The temperature difference power generation component of M363268 can be used for power generation and power supply display temperature, but because it is built in the bottom of the container body (cup body), it still cannot be transferred to other cups, and the cup is easy to be cupped when cleaning. The electronic components inside the body are damaged by moisture and the like, thus affecting the service life. At the same time, the thermoelectric power generation assembly is not used to provide a cooling/heating function. Furthermore, since the thermal energy is usually transmitted and escaped by the vapor, if the thermoelectric power generation component is placed at the bottom of the cup body, most of the heat energy cannot be effectively received at the bottom of the cup body, thereby affecting the power generation efficiency. The temperature measured at the bottom of the cup is also not the highest liquid temperature. Further, if a thermoelectric element, a temperature display or the like is provided in the cup body, it can be used only for the same cup. The general-purpose type cannot be designed to be applied to different cups or existing cups, so that the use margin is limited. Therefore, it is necessary to provide a cup cover structure having thermoelectric elements to solve the problems of the prior art. SUMMARY OF THE INVENTION The main object of the present invention is to provide a cup cover structure having a thermoelectric element, wherein the cup cover absorbs heat energy in the cup by the thermoelectric element to generate electricity, and the electric energy is used to detect the temperature inside the display cup or subsequent use. For cooling/heating work, it is beneficial to improve the functionality of the lid-type products and the ease of use of the cup-type products. A secondary object of the present invention is to provide a cup 201144170 cap structure having a thermoelectric element, wherein the thermoelectric element is disposed inside the cup cover, since the cup cover is disposed separately from the cup body, so cleaning the cup body does not cause the inner component of the cup cover to be damp. Therefore, it is beneficial to improve the service life of the lid type products. Another object of the present invention is to provide a cup construction having a thermoelectric element, wherein the cup cover can be designed in a universal form to accommodate different opening sizes of the various cups, thus facilitating the expansion of the application range of the cup-type product. In order to achieve the above object, the present invention provides a cup cover structure having a thermoelectric element, comprising: a cup cover having an inner space; and a thermoelectric module disposed in the inner space of the cup cover and provided a control circuit; a rechargeable battery electrically connected to the control circuit; a thermoelectric element disposed at the bottom of the cup cover and electrically connected to the control circuit, wherein the control circuit is configured to switch the thermoelectric element and the rechargeable battery Between

Next, hot water or other hot beverage (e.g., hot tea or hot coffee, etc.) is injected into the cup 2, and the lid 1 is covered with the lid 1 at the opening of the cup 2. At this time, since the hot water in the cup 2 generates a large amount of radiant heat energy or high temperature vapor upward, the radiant heat energy or the high temperature vapor will rise, and conduct heat to the lower side of the thermoelectric element 33 at the bottom of the lid 1 for insulation. Ceramics. As a result, the thermal energy will cause a temperature difference between the upper and lower sides of the thermoelectric element 33 (e.g., a temperature difference between 25 ° C and 90 ° C), so that the thermoelectric element 33 can use the temperature difference to generate electricity. . The electric energy can be stored in the rechargeable battery 32 via the control circuit 31, and used to drive the temperature display unit 34 and the temperature sensor 35, thereby displaying the temperature inside the cup (for example, displaying 90 ° C), so that the user can visually judge the cup. Internal water temperature. 11 201144170 Furthermore, under certain usage requirements, the user can also switch to the "power generation/storage," function of the switch 36 to enable the thermoelectric element 33 to generate electricity and simply store electrical energy without displaying temperature. The control circuit 31 completely stores the electrical energy in the rechargeable battery 32, and is not used to drive the temperature display unit 34 and the temperature sensor 35. After storing the power for a period of time, the user can switch to the switch again. The "heating" or "cooling" of the 36" enables the shaft electrical unit 33 to be subjected to mechanical heat or refrigeration to heat or cool the original liquid or another liquid in the cup 2. Thus, the present invention The above design is advantageous for improving the functionality and ease of use of the product of the cup cover. Please refer to Figures 4, 5, 6, 7 and 8 to disclose the second, third and fourth aspects of the present invention, respectively. The cup cover structure of the fifth and sixth embodiments having a thermoelectric element is similar to the first embodiment of the present invention, and generally uses the same component name and figure number. As shown in Figures 4, 5 and 6, the second , the third and fourth embodiments are different The bottom of the cup cover (ie, the lower surface) is suitably provided with a threaded joint 11 so as to be affixed to the opening of the cup 2, and is located around the thermoelectric module 3 at the bottom of the lid 1 A heat insulating layer 13 may be provided to prevent heat loss. Further, as shown in Fig. 7, the fifth embodiment is provided with a flange at a suitable position on the bottom (i.e., the lower surface) of another type of cup cover 1. 12, so that the snap-in card is coupled to the inner edge of the opening of the cup 2. If necessary, the temperature sensor 35 can also be selectively protruded from the bottom surface of the cup cover in the form of a protruding rod so as to approach or extend Entering the surface of the liquid in the cup 2 to measure the value closer to the actual maximum temperature of the liquid. As shown in Fig. 8 12, 201144170 No, the sixth embodiment is attached to the bottom of a disc-shaped lid 1 (i.e., The surface of the lip is selected to be provided with an elastic pad body 14. When the cup cover 1 is provided with the elastic pad body 14, the cup cover 1 is used as a universal cup cover, which is suitable for various cup bodies 2 The different opening sizes are therefore beneficial for expanding the range of applications for the lid products. In addition, the lid 1 of the present invention may be of other types, and the type of the lid 1 is not intended to limit the present invention. In other embodiments of the invention, the outer surface of the lid 1 is in a suitable position (for example, an upper surface or The circumferential surface can also be selectively provided with a power supply hole (not shown) electrically connected to the control circuit 31. Thus, the present invention can selectively output the stored energy of the rechargeable battery 32 to the power supply via the power supply hole. An external device, such as powering a mobile phone or a small fan; or alternatively, an external power can be input to the rechargeable battery 32 via the power hole to supplement the rechargeable battery 32 for subsequent use in driving the battery The thermoelectric element 33 can perform heating or cooling work. As described above, compared with the conventional thermoelectrically cooled wafer related article design, it is built into the cup itself or the cup holder, so that the component is easily damaged and cannot be applied to various cups. The disadvantages are not applied to the lid structure. The invention of FIGS. 1 to 6 is provided with the thermoelectric element 33 in the lid 1 for absorbing the heat energy in the cup 2 for power generation and using electric energy. It is useful for improving the functionality and ease of use of the lid-type product by displaying the temperature inside the cup or for subsequent cooling/heating work. Since the thermoelectric element 33 is disposed inside the lid 1 of the present invention and the lid 1 is generally disposed separately from the cup 2, the cleaning of the cup 2 does not result in 13 201144170 causing the inside of the lid 1 The components are damp, which helps to improve the service life of the lid products. Further, as shown in Fig. 6, the lid 1 can be designed in a general-purpose type to be applied to different opening sizes of the various cups 2, thereby facilitating the expansion of the application range of the lid-type products. The present invention has been disclosed in its preferred embodiments, and is not intended to limit the invention, and the present invention may be modified and modified without departing from the spirit and scope of the invention. The scope of protection is subject to the definition of the scope of the patent application.
