Abstract

The invention relates to the technical field of hair dryers, and discloses a constant temperature control method of a hair dryer. The hair dryer comprises an air duct, a handle and a self-heating body, the resistance value of the self-heating body changes along with the change of the temperature of the self-heating body, and the self-heating body is arranged in the air duct. A fan, a motor and a heating wire are arranged in the air duct. A main board is arranged in the handle, and a temperature detection circuit, a control unit and a power control circuit are arranged on the main board. The temperature detection circuit measures the resistance value of the self-heating body and feeds back a resistance value signal to the control unit, and the control unit controls heating of the heating wire through the power control circuit according to the received resistance value signal so that air blown out of the air outlet of the air duct can be in a constant-temperature state. Through the powercontrol circuit, heating of the heating wire can be controlled, and air blown out of the air duct is in a constant-temperature state. The self-heating body is arranged in the air duct and deviates from the high-temperature environment of the air outlet, installation is convenient and time-saving, the temperature error of the self-heating body is small, the feedback sensitivity is high, and high-precision constant-temperature control over the hair dryer is achieved.

Description

technical field [0001] The patent of the present invention relates to the technical field of hair dryers, in particular, to a constant temperature control method of hair dryers. Background technique [0002] With the improvement of the quality of life, hair dryers have become a necessity in people's daily life, and every household is basically equipped with a hair dryer. [0003] In the prior art, the constant temperature control method of the hair dryer is to use a temperature sensor, a thermistor or an infrared element to detect the temperature of the wind blown out of the air outlet of the hair dryer, and to feed back the detected information to the main board, and then through The main board controls the working state of the motor or heating wire, so as to achieve the purpose of temperature control. [0004] At present, the temperature sensor needs to be configured with matching parts, and it is installed in a high-temperature environment near the air outlet, which not ...
