And a physical switch module is arranged outside the shell.

Furthermore, the power module is connected with other modules and the physical switch module in the shell and supplies power, the signal output end of the acceleration sensor is connected with the control unit module, and the signal output end of the timer is connected with the control unit. The signal output end of the control unit module is connected with the functional switch module. The signal output end of the physical switch module outside the shell is connected with the functional switch module. And the signal output end of the functional switch module is connected with and controls the opening and closing of the motor containing the fan blades and the heating module.

Furthermore, a physical switch module outside the shell is connected with a functional switch module in the shell, a control instruction can be sent to the functional switch module through the operation of the physical switch module, and the signal output end of the functional switch module is connected with and controls the opening and closing of the motor containing the fan blade and the heating module.

Further, when the physical switch module is switched from the off state to the on state, the physical switch module sends a control instruction to the function switch module, the function switch module starts the motor containing the fan blades and the heating module, and the blower is in the on state. When the blower is in an on state, the acceleration sensor and the timer output acceleration state information and timing data to the control unit module. If the acceleration sensor senses the acceleration generated by the blower in a certain direction, and the acceleration state information shows that the blower is in a motion state, the control unit module does not send a control instruction to the function switch module, and the blower continues to be kept in a starting state. If the acceleration state information shows that the blower is in a static state, the control unit module counts the time length of the blower in an open and static state through the acceleration state information of the acceleration sensor and timing data of the timer. If the time length of the blower in the opening and static state exceeds the set safe working time threshold time length, such as 5 seconds, the control unit module sends a control instruction to the function switch module, the motor containing the fan blades and the heating module are closed, the blower is switched from the opening state to the closing state, and at the moment, the blower can be adjusted to the opening state again in a mode of firstly closing the physical switch module and then re-opening the blower.

Further, when the physical switch module is in the off state, the blower is always in the off state.

The utility model has the advantages that: when a user starts the blower to be used through the physical switch module (namely, the user normally starts the blower to be used), the acceleration sensor and the timer in the blower record the motion state of the blower in real time, and the blower is automatically controlled to be in the starting state or to be closed according to the motion state of the blower. When the user normally uses the hair drier, the hair drier can be shaken or moved generally, namely, the hair drier moves, the acceleration sensor can accurately sense the acceleration generated by the hair drier in a certain direction, and at the moment, the hair drier can continue to work normally in an opening state. When the blower in the opening state is in the abnormal working state of long-time rest, the acceleration sensor cannot sense the acceleration generated by the blower in a certain direction, and the timer can accurately record the time length. When the duration of the abnormal working state that the blower is started and is static exceeds the set safe working time threshold duration (for example, 5 seconds), the control unit module sends a control instruction to the function switch module, and the motor containing the fan blades and the heating module are closed, so that the blower is switched from the starting state to the closing state, and safety accidents such as scalding of the skin of a user or firing of flammable materials caused by the fact that the blower is fixed to blow hot air in the same direction for a long time can be effectively prevented.
