Method and device for controlling a battery-based hair dryer

Abstract

The present invention relates to the technical field of hair dryer control, in particular to a method and device for controlling a battery-type hair dryer, which includes obtaining real-time data of the current battery voltage through a battery detection circuit; To reversely deduce the program to adjust the duty cycle value to achieve constant power wind heating control; adjust the duty cycle value according to the obtained real-time data of the battery voltage and the set gradual wind speed to control the voltage value at both ends of the motor to achieve within a certain period of time Gradual wind speed adjustment. The control method of the battery-type hair dryer provided by the present invention uses the battery detection circuit to obtain the real-time data of the current battery voltage, and then controls the temperature and wind speed within a preset range through a software algorithm, which meets the needs of the hair surface for the wind temperature, Make the human body feel the touch of the wind temperature basically the same before and after. It not only achieves the effect of maintaining a constant temperature and continuously adjusting the wind speed, but also saves battery power and increases battery life.

Description

technical field [0001] The invention relates to the technical field of hair dryer control, in particular to a method and equipment for controlling a battery hair dryer. Background technique [0002] Hair dryer is a common heating equipment in daily life. According to different power sources, it is mainly divided into AC hair dryer and battery type hair dryer. temperature. The battery-type hair dryer needs to be powered by batteries, so the heating power cannot be very large, usually only one or two hundred watts, and the battery voltage will slowly drop during the actual work process, so that the power of the hair dryer will gradually decrease. Small. Because of the reduction of its power, the temperature of the wind blown by the hair dryer decreases, and the heat provided by it is not enough for the evaporation and absorption of water, and cannot meet the comfortable temperature required by people to blow hair. [0003] For example, the application number is CN2019223040...

Problems solved by technology

However, its disadvantage is that, on the one hand, the power of this type of hair dryer is low, which cannot meet the needs of people's hair surface for air temperature; on the other hand, the air temperature cannot be adjusted, and it is difficult for users to adjust , making the difference between the experience in the early stage and the post-blowing period is quite large
