Description of the Invention: [Technical Field] The present invention relates to an irreversible temperature warning device, and more particularly to a warning device structure that can adjust a required warning temperature to alert the user. [Prior Art] Currently, there are many kinds of inorganic color-changing pigments which are known to irreversibly display temperature, and are mainly sulfates, nitrates, chromates, sulfides containing elements such as lead, nickel, cobalt, iron, cadmium, lithium, and zinc. And other compounds. In general, the foregoing oxides are often used as ceramic color-changing pigments at higher temperatures (8 〇 (rc or more), and their color-changing mechanism involves thermal decomposition, oxidation or solid phase reaction, which provides the desired color when the ceramic is fired. Although inorganic color-changing materials have better temperature resistance, the color-changing temperature is biased, and the use in low-temperature fields is limited. At present, low-temperature inorganic color-changing materials (loot: below) are mainly Co and Ni inorganic salts with crystal water, and the main principle of color change is It is the gain or loss of crystal water that causes color change, for example: αα22ς^12Ν4ΐ()Η2〇^ c〇c “ ”N4+1qH9〇辛刀色—天监一 ^

The biggest disadvantages are: 1. The temperature cannot be adjusted, 2. The changed color cannot be adjusted, and 3 cannot be used to make the warning device below room temperature. Generally, irreversible temperature warning devices are used in the temperature monitoring market of machinery and equipment. Since the temperature limit of use of various types of machinery and equipment is different, so the temperature cannot be adjusted, it cannot be designed for a specific use environment or machine, which causes inconvenience in use and even affects the function of the warning device. Since the current irreversible temperature warning device does not provide the customer with the ability to select colors, the user can only choose the existing color. However, because the color cannot be adjusted, the user cannot make a link between color management and crisis management, or the design conforms to the color change of the product. The low-temperature warning device is a part that is more suitable for people's livelihood, such as fresh milk, cosmetics, yogurt, fish, shrimp, etc. Therefore, if you can design an irreversible temperature warning device for low temperature use, you can cut the current irreversible temperature-sensitive products into the market where you live in a normal life. The business opportunities that can be expanded are not limited. In addition, many consumers expect that there can be a simple device (such as a tape or a label) that can indicate the target temperature of the device, from ambient 1263040 4 to 44, the ambient temperature experienced. Change; or whether the subject matter of the device's warning is more than 1 degree in the interval between personnel inspections. For example, this device may be suitable for monitoring the freshness of fresh foods (eg fish, shrimp 'fresh milk, meat) or special products (lips and medicines), confirming the temperature during production, transportation and storage. Increased, which affects product quality; in addition, this warning device can also be used to monitor whether a machine has exceeded the operating temperature to prevent possible malfunctions. Therefore, the inventor of the present invention wants to design an irreversible temperature alarm device to overcome the above shortcomings, and is inexpensive and can be fully supplied for people's livelihood. SUMMARY OF THE INVENTION The main object of the present invention is to provide an anti-temperature warning device that can warn temperature and color according to environmental or manufacturer requirements, and the adjustable temperature range is -5 〇.卜_ For the above purpose, the device has at least one protective layer, a display layer, and a temperature control layer, and the adhesive layer, the display layer, and the temperature control layer are sequentially contacted and closed in accordance with the situation, and the rear view is followed. It is desirable to include an adhesive layer under the temperature control layer. According to the above configuration, the temperature control layer produces a phase change between the solid and the liquid phase due to the set temperature, and utilizes the sensible layer to absorb the temperature control layer which becomes a liquid phase due to the temperature (this layer can be used according to the customer. For the color requirement, add the general dye), and turn the display of the original white (or set to a safe color) into a color that is set to be dangerous, and the warning function is achieved. [Embodiment] The present invention relates to an irreversible temperature warning agricultural installation. As shown in Fig. 1, the apparatus includes a protective layer 10' having a first major surface and a second major surface 12. a display layer 20 having a first major surface 21 and a second major surface 22, wherein the first major surface of the display layer 2" is in contact with the second major surface 12 of the protective layer 10; a temperature control layer 3? a main surface 31 and a second main surface 32, wherein the first main surface 31 of the temperature control layer 30 is in contact with the second main surface 22 of the display layer 2A; the adhesive layer 40' has a first main surface 41 and a second main surface The surface 42, the first main surface 41 of the intermediate adhesive layer 40 is in contact with the other-surface 32 of the temperature control layer 30, and the substrate is separately described as follows: Protective layer: The present invention The protective layer Π) may be a transparent or translucent natural or artificial product & its main function is to protect the surface of the device from other factors such as weather, dust, handling or use. The same as 1263040 T, in In some embodiments, the protective layer ίο can also be designed to accommodate a variety of printing techniques, printing or pattern changes, including printing techniques such as inkjet printing, gravure printing, letterpress printing, screen printing, and the like. In addition, the protective layer 10 can also be multi-layered The film is disclosed in, for example, U.S. Patent No. 6,117,530. The protective layer 1G can be used to adhere the protective layer to other parts of the device by means of a viscous material. Alternatively, it can be laminated at a high temperature. The method of sticking to other parts of the device eliminates the need to use an adhesive layer. Display layer · · · The display layer 20 of the present invention has the main function of transporting fluid and displaying the color of the fluid on the display layer 2 The first main surface 2 causes the device to produce a color change warning function. The display layer 2 is made of a hydrophilic or lipophilic material according to the design of the temperature control layer 30. For example, the display layer 2〇 It may be a porous film or coating; a hydrophilic or lipophilic fiber based f, such as various papers. In many applications, the display layer 20 may be colored, white or any other set to be safe. Color. Overall, when the irreversible temperature warning device has not reached the set temperature, the display layer 2 is = bright, and the user cannot widen the display through the display 2.

The phase change material may be an organic compound that is lipophilic or hydrophilic (or a combination of both) or It is an inorganic compound or a combination of organic and inorganic. In general, the temperature control layer 3 is in a liquid state in which the temperature is lower than the set temperature (4), and the temperature is higher than the set temperature. And use this phase change function as a way to set the warning temperature. The temperature control layer 30 of the present invention can fix the dye or pigment in the temperature control layer 30 in the solid state; in the liquid state, it can carry the dye or pigment to enable the dye and pigment to pass through the second main surface 22 of the display layer 20, The purpose of being recognized by the transparent protective layer 10 is achieved.
