Overheat alarm device for power line of household electrical appliance

Abstract

The invention discloses an overheat alarm device for a power line of a household appliance, and belongs to the technical field of overheat alarm devices. According to the overheat alarm device, an overheat driven-adjustment spring, a light-reflecting alarm ball and a sound production alarm ball are adopted, when the power line is overheated, under the heat conduction effect of a line pasting heat conduction sheet and a heat conduction rod, the overheat driven-adjustment spring can recover to a high-temperature phase shape, so that the alarm function of the light-reflecting alarm ball and the sound production alarm ball is triggered, a light-reflecting alarm block in the light-reflecting alarm ball can give an alarm through light reflection, and a warning whistle in the sound production alarm ball can give a sound to give an alarm, so that the overheat alarm device can give an alarm to people through sound and light modes, and people can find an overheating phenomenon of the power line in time, therefore, the safety problem caused by overheating of the power line is effectively reduced, the safety performance is greatly improved. The device can be directly matched with an existing power line so as to be used, does not need to modify the power line, is simple to operate, does not need a power supply, and is high in practicability.

Description

technical field [0001] The invention relates to the technical field of overheating alarm devices, and more specifically, relates to an overheating alarm device for power cords of household appliances. Background technique [0002] Household appliances mainly refer to various electrical appliances and electronic appliances used in homes and similar places. Also known as civil appliances, household appliances. Household appliances liberate people from heavy, trivial and time-consuming housework, create a more comfortable and beautiful living and working environment that is more conducive to physical and mental health, and provide rich and colorful cultural and entertainment conditions. necessities of life. [0003] Household appliances are usually equipped with a power cord for connection to the socket. After a long-term use of the power cord, it is easy to cause the power cord to overheat due to aging or poor quality of the socket. If it is not handled in time, it will not ...

[0003] Household appliances are usually equipped with a power cord for connection to the socket. After a long-term use of the power cord, it is easy to cause the power cord to overheat due to aging or poor quality of the socket. If it is not handled in time, it will not only cause the power cord damage, and it is easy to damage electrical appliances, and even cause a fire in serious cases

[0004] In the prior art, the leakage protector is usually equipped in the household power supply system. Although the leakage protector has overload and short-circuit protection functions, it can be used to protect the overload and short-circuit of the circuit or electrical appliances, but in some cases, the overheating of the power line will not trigger Leakage protector, and people do not touch the power line, and it is difficult to find that the power line is overheated, causing overheating of the power line will easily cause safety problems, and there is a huge potential safety hazard
