Abstract

The invention relates to an intelligent and safe electric heating blanket which comprises a blanket body, a heating element composed of a nickel alloy low-voltage heating wire is arranged inside the blanket body, and a high-precision temperature sensor is set inside the heating element. The intelligent and safe electric heating blanket also comprises a control device with a MCU operation control unit, the regulation of the temperature range of 15 DEG C to 50 DEG C is achieved by controlling a MOS switch. The intelligent and safe electric heating blanket also comprises an isolation transformerDC power supply which outputs low-voltage direct current with the voltage lower than 24V. According to the invention, the hidden danger of the electric shock of a human body is fundamentally solved, the electromagnetic interference is completely eliminated, and the realization of the acquisition precision of + / -0.2 DEG C through an internal software algorithm is facilitated. The MCU operation control unit achieves the regulation of the temperature range of 15 DEG C to 50 DEG C by controlling the MOS switch, the control structure is simple, the loss is small, the response speed is fast. Vref can realize the instantaneous voltage rise to a safe voltage range, the heating power can be quickly increased, the reduction of a startup warm-up time is facilitated, and the acarus killing function isrealized.

Description

technical field

[0001] The invention relates to the technical field of electric heating, in particular to an intelligent safety electric blanket and a heating method that can not only ensure the absolute safety of users, but also realize temperature control on the basis of meeting the temperature requirements of different regions of the human body. Background technique

[0002] The common electric blanket is a kind of contact electric heating appliance. It weaves or sews the special soft cable electric heating element whose insulation performance reaches a certain safety standard into the blanket in the shape of a snake. When it is energized, it can generate appropriate heat. Some of the heat is balanced and constant, and some can be controlled and adjusted.

[0003] Different electric blankets have their own outstanding features, for example, they are innovative in terms of power consumption, temperature regulation, ease of use, range of use, and durability.
