(3) summary of the invention
In order to overcome deficiency of the prior art, the utility model provides a kind of higher DC electrothermal blanket of security that adopts Switching Power Supply and have warning function.
The technical scheme in the invention for solving the technical problem is:
A kind of DC electrothermal blanket, comprise electric blanket, be located at heating element heater and the controller of controlling electric blanket work in the electric blanket, described controller comprises and carries out the powered switch power module, the data of input are handled and are generated the MCU central control module of control signal or demonstration signal, the switch module of control opening and closing, regulate the module of transferring the files of electric blanket heating power size, the display module that shows fault and state according to the demonstration signal of MCU central control module output, regulate and control the heating element heater PWM control module of heat time heating time according to the module of transferring the files, the output of switch power module connects the power input of MCU central controller, the output of the module of transferring the files connects the signal input part of MCU central control module, the output of MCU central control module connects the input of display module and PWM control module, and switch module connects the MCU central control module.
The Switching Power Supply power supply, accomplished isolation fully with human body, realize the real safe and reliable of electric blanket in the past, the module of transferring the files is input to the MCU central control module with signal, after handling, signal is transferred to the PWM control module, the PWM control module is adjusted the heat time heating time of heating element heater, i.e. the heating power size thus according to the signal modulation output pulse width of input.Export simultaneously when the MCU central control module carries out control signal output again and show that signal is to display module.
Controller also comprises detecting the buzzer output module of reporting to the police under non-loaded load detection module and the immunization with gD DNA vaccine, the output of load detection module connects the input of MCU central control module, and the input of buzzer output module connects the output of MCU central control module.When responsible detection module detects when non-loaded, send alarm signal by the MCU central control module and give the buzzer output module, buzzer generation alarm, and be shown to the user by display module.
Controller also comprises the heat driven module, and the output of described PWM control module connects the input of described heat driven module.The PWM control module modulates heat time heating time to heating element heater by the pulsewidth of regulation and control output pulse, and by the heat driven module heating element heater is driven.
The module of transferring the files is electrically connected with the gear adjuster, and described gear adjuster comprises low grade, middle-grade and high-grade.The user is by selecting to adjust the heating power size to the gear on the gear adjuster.
The beneficial effects of the utility model are: the utility model adopts Switching Power Supply to power, the isolation fully with human body has been accomplished in Switching Power Supply power supply, realizes the real safe and reliable of electric blanket, and non-loaded warning function is arranged, judge for the client more intuitively.
(4) description of drawings
