Body condense into vapor and caused by mask use it is uncomfortable；By being monitored in real time to the temperature on the inside of mask body, then root
Pwm pulse is controlled according to real time temperature, can effectively be avoided too high or too low for temperature on the inside of mask body.
Detailed description of the invention
Fig. 1 is the structural block diagram that mask is heated in first embodiment of the invention.
Fig. 2 is the flow chart of the middle detection system of first embodiment of the invention method for heating and controlling.
Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with drawings and the embodiments,
The present invention will be described in further detail.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention,
It is not intended to limit the present invention.
With reference to Fig. 1, first embodiment of the invention provides a kind of heating mask, including mask body, further includes:
Heating unit, for being heated to the air entered on the inside of mask body；
Acquisition unit, for acquiring the temperature parameter on the inside of mask body；
Processor,
Storage medium stores a plurality of instruction in the storage medium, the processor is made when described instruction is executed by processor
The collected temperature parameter of the acquisition unit is received, and controls the adjusting pwm pulse for inputting the heating unit.
It should be noted that heating mask of the invention includes but is not limited to protective face mask, breathing mask etc..Of the invention
Temperature on the inside of mask body can be controlled by the adjusting pwm pulse of control input heating unit by heating mask, so as to keep away
Exempt from the too low stimulation caused by user of environment temperature；The gas that can also effectively avoid user to breathe out simultaneously condenses into water steaming
Gas and caused by mask use it is uncomfortable.
Further, the heating mask further includes power supply unit, and said supply unit is used to supply for the heating unit
Electricity.
Further, said supply unit can be battery, can also be external power supply.
Further, the acquisition unit is temperature sensor.Mask body can be monitored in real time by temperature sensor
