Electric heating pad power cut-off device and method

Abstract

The invention relates to an electric heating pad power cut-off device and method. The electric heating pad is provided with an induction component. The induction component and an electric heating wireembedded in the mattress are separately embedded to enable initialization of the set time of a timing sensor by short circuit of the power supply. The induction component comprises a box body which is split and provided with a storage cavity; a current flow part which is arranged in the storage cavity of the box body and connected to the timing sensor by an electric wire; and current circulationballs which are arranged on the current flow part and freely and movably perform the short circuit function of the current. The current flow part comprises an aluminum plate having a circular shape and presenting to be curved downward from the outer peripheral edge to the center; an insulating member which is coated on the entire upper surface of the aluminum plate so as to cut off conduction of the current; and positive and negative copper wires which are coated in a snail-like shape on the upper surface of the insulating member from the center with a spacing at which the current circulationballs can be contacted.

Description

technical field [0001] The present invention relates to an electric heating pad, especially a power cut-off device and method of the electric heating pad, that is, if the mat (Mat) is not shaken within a certain period of time when the power is turned on, it is regarded as not in use The mat automatically cuts off the power. Background technique [0002] Generally speaking, the electric heating pad will bury the electric heating wires that emit heat after receiving the power supply at a certain distance inside the mat that is made into a predetermined size according to the purpose of use. The heating wire embedded in the mat heats up the mat, allowing the user to rest or sleep in a warm state. [0003] This existing heating pad (10) such as figure 1 As shown, it includes a mattress (20), an electric heating wire (30) embedded in the above-mentioned mat, a power regulator (40) that operates the on and off of the power supply under the state connected to the above-mentioned ...

Problems solved by technology

[0005] However, if the aforementioned electric heating pad is not used when the power is turned on by the user, the power supply needs to be turned off (off) to stop the power supply and save power, and it can also prevent fire hazards caused by overheating. If it is not used, especially when there is no one at home for a long time, there may be a danger of safety accidents such as fire alarms caused by overheating. Therefore, a power cut-off device is installed on the power conditioner so that it will automatically turn off after the set time has passed. Cut off the power, regardless of whether the user is using the mat or the user is not there, the power will be automatically cut off as long as the set time is reached, so as to reduce power waste or prevent fire caused by overheating when the user is not there. Accidents are dangerous, but when the set time is reached during use, the power will be automatically cut off and the power needs to be turned on again, and such situations will cause users to feel complicated and annoying
