Embodiment 1

[0042] refer to figure 2 As shown, the outer edge of the plug 1 is provided with a heat transfer unit 11, and the outer edge of the heat transfer unit 11 is covered with a thermochromic ink 2, and the thermochromic ink 2 can be printed on the heat transfer unit 11, or coated On the heat transfer unit 11, or spray on the heat transfer unit 11, or immerse the heat transfer unit 11 in the thermochromic ink 2, so that the thermochromic ink 2 is attached thereto; in this embodiment , the heat transfer unit 11 is a colored plastic film.

[0043] When the working temperature of the plug 1 rises abnormally, and the temperature reaches or exceeds the critical color change temperature of the thermochromic ink 2, the thermochromic ink 2 will change color and become transparent, so that the original thermochromic ink 2 covers The color of the heat transfer unit 11 emerges, and the above-mentioned color change can generate a warning effect to the user.

Embodiment 2

[0045] refer to image 3 As shown, the plug 1A is provided with an upper housing 11A and a lower housing 12A. Since the upper housing 11A directly contacts the copper sheet 13A, it can directly sense the working temperature of the copper sheet 13A. The outer edge of the upper housing 11A is covered with a temperature-sensitive discoloration Ink 2A, the thermochromic ink 2A ​​is directly printed on the upper casing 11A.

[0046] When the working temperature accepted by the upper case 11A reaches or exceeds the critical color change temperature of the thermochromic ink 2A, the thermochromic ink 2A ​​becomes transparent, making the color of the upper case 11A previously covered by the thermochromic ink 2A was revealed. And if the upper casing 11A is made of transparent material, the copper sheet 13A and other components inside the plug 1A will be exposed, which also has a warning function.

Embodiment 3

[0048] refer to Figure 4 As shown, the plug 1B is an integral coating type with glue injection, and a groove 11B is provided on the upper edge of the plug 1B. The groove 11B is used for inserting and assembling a piece 12B. The piece 12B is printed with a temperature-sensitive color-changing ink 2B. The temperature-sensitive color-changing ink 2B on the body 12B will turn transparent due to the increase of the working temperature, so that the color of the sheet body 12B covered by the temperature-sensitive color-changing ink 2B is revealed, so as to generate a warning function.

Abstract

This invention relates to one plug overheat alarm method, which comprises the following steps: a, selecting heat conductive unit; b, covering temperature inductive oil ink on the surface of the conductive unit to make the oil ink to receive the transmit temperature; c, locating the transmit unit into plug work temperature position; d, using temperature changing oil ink unit to receive phoneme to monitor plug temperature situations.

Description

technical field [0001] The invention belongs to a method for warning the abnormal temperature of a plug, in particular to a method of coating the surface of the plug with thermochromic ink, and changing the color by sensing the abnormal working temperature of the plug with the thermochromic ink to obtain a safety warning function. Background technique [0002] Improper use of electrical appliances can easily lead to excessive loads, short-circuiting of wires and accidents. Since most short-circuit phenomena cannot be detected in advance, users cannot be warned in real time. Although a small number of electrical appliances have built-in alarms, the manufacturing cost is relatively high. In addition, some electrical appliances are equipped with an overload protection device, which can automatically cut off the power when overloaded to avoid overheating or short circuit, but the overload protection device only has the function of power failure protection, and cannot warn the use...
