A hair perming device and its temperature control circuit are disclosed. The temperature control circuit for a hair perming device is electrically connected with a heater of the hair penning device and comprises a main control module and a trigger module. The main control module controls the trigger module to be switched on such that a control signal outputted by the main control module can be sent to the heater for heating, and meanwhile for detects a working state of the trigger module. When a failure of the trigger module is detected, the main control module controls the trigger module to be switched off such that a continuous heating of the heater is stopped. When a failure of the trigger module is detected, the electrical power supply path of the heater is disconnected, and a continuous heating of the heater is stopped for avoiding excessive high temperature.
A temperature control circuit for a hair perming device electrically connected with a heater of the hair perming device, comprising a main control module and a trigger module, wherein the main control module is used for controlling the trigger module to be switched on such that a control signal outputted by the main control module can be sent to the heater for heating, and meanwhile the main control module is used for detecting a working state of the trigger module, wherein when a failure of the trigger module is detected, the main control module is used for controlling the trigger module to be switched off such that a continuous heating of the heater is stopped.
A hair perming device comprising a power supply input, a heater and a temperature control circuit, wherein the heater is connected in series between the power supply input and the temperature control circuit, wherein the temperature control circuit comprises a main control module and a trigger module, wherein the main control module is used for controlling the trigger module to be switched on such that a control signal outputted by the main control module can be sent to the heater for heating, and meanwhile the main control module is used for detecting a working state of the trigger module, wherein when a failure of the trigger module is detected, the main control module is used for controlling the trigger module to be switched off such that a continuous heating of the heater is stopped.
