Intelligent heating blanket and control method thereof

Abstract

The invention discloses an intelligent heating blanket which comprises a heating blanket body, a power supply, a controller, a relay and a temperature sensor and a prompting device arranged in the heating blanket body, the heating blanket body is connected to commercial power via the relay, the power supply, relay, temperature sensor and prompting device are all connected with the controller, andthe power supply is connected with the temperature sensor. The intelligent heating blanket uses electronics including the sensor, a single-chip microcomputer, an LCD display screen and a relay in theprior art, so that the structure is simple and the cost is low; and functions are comprehensive, the heating blanket can be powered on / off automatically according to whether there is a user as well asthe surface temperature of the heating blanket, and the heating blanket can be powered on / off via a mobile terminal.

Description

technical field [0001] The invention relates to the technical field of electric heating blankets, in particular to an intelligent electric heating blanket and a control method thereof. Background technique [0002] Electric blankets are warming products that almost every household has. Generally, there is a built-in resistance wire. After the power is turned on, the current flows through the resistance wire to generate heat, so as to achieve the effect of keeping the bed warm. Because of its low price and convenient use, it is widely used. [0003] Electric blankets in the prior art generally include an electric blanket body and a switch. The switch is provided with two or three temperature levels, and people can use the switch to adjust the temperature of the electric blanket. However, this kind of electric blanket can only manually adjust the temperature of the electric blanket, which becomes very inconvenient after the user falls asleep. It should be turned off before go...

AI Technical Summary

Problems solved by technology

However, this kind of electric blanket can only manually adjust the temperature of the electric blanket, which becomes very inconvenient after the user falls asleep. It should be turned off before going to bed. If the user forgets to turn off the electric blanket before going to sleep, then, Users are often woken up by heat in the second half of the night

If the user forgets to turn off the electric blanket, there will be serious safety hazards in the electric blanket working for a long time when no one is using it, and it may even cause various accidents such as fire.

Therefore, the current electric blankets do not have the functions of automatic temperature adjustment and automatic shutdown, and users cannot set the opening time according to their own needs. The functions of the existing electric blankets are not perfect, so further improvement is needed in the electric blanket technology.

[0004] On the whole, the functions of the electric blankets in the prior art mainly have the following deficiencies: 1. The existing electric blankets are not intelligent enough to control the automatic opening and closing of the electric blankets according to the actual temperature; 2. It is impossible to judge whether someone uses the electric blankets, And when no one is using the electric blanket, turn off the electric blanket; 3. It is impossible to control the opening and closing of the electric blanket through the mobile terminal; 4. It is impossible to control the temperature of the electric blanket within the range set by the user
