Abstract

The invention relates to a motor-based control circuit, an electric hair dryer and a physiotherapeutic apparatus. The motor-based control circuit comprises a motor unit, a first switch unit, a heatingunit and a second switch unit. The motor unit includes a motor. The switch unit includes a first switch and a second switch. When receiving a motor operation control signal transmitted by a motor control line and a low-voltage signal output by the first switch, the motor is started and outputs a switch control signal to the control end of the second switch unit. The second switch unit switches onthe input end of the second switch unit and the output end of the second switch unit according to the switch control signal. The heating unit is started and generates heat when the input end and output end of the second switch unit are switched on and when heating unit receives a high-voltage signal output by the second switch. The heating unit activates the heating function only after the motoris started. Therefore, the motor-based control circuit avoids thermal failure and safety accidents caused by the lack of an air cooling system.

Description

technical field [0001] The invention relates to the technical field of motor control, in particular to a motor-based control circuit, hair dryer and physiotherapy equipment. Background technique [0002] The motor consists of a motor body and a driver, and is a self-controlled product. Motors have been widely used in various instrument products due to their strong controllability. For example, in hair dryers, motors can be used to control the speed of the fan impeller, thereby realizing the adjustment of the wind speed of the hair dryer. However, most of the existing hair dryers have adjustable hot air and cold air functions, and the adjustment function of the hair dryer is mainly completed by two multi-throw switches. Specifically, power is supplied to the motor through one of the switches to form a motor ( The low wind gear and the high wind gear of the fan); the on and off of the heating wire is controlled by another switch to form the low-level hot air and the high-leve...
